Method and device for determining power
Technical field
[0001]
The present invention relates to the field of communications, in particular to a method and device for determining power.
Background technique
[0002]
In the random access (RA, Random Access) process, the user equipment (UE, User Equipment) sends message 1 (MSG1) to the network side to make a random access request, and the network side sends message 2 (MSG2) in a broadcast manner. In MSG2, the network side indicates the backoff time used by the user equipment that has not successfully received a random access response (RAR, Random Access Response).
[0003]
In addition, the random access process can be divided into Contention Based Random Access (CBRA) and Contention-Free Random Access (CFRA). In CBRA, UEs share random access preamble (Random Access Preamble), therefore, random access conflicts may occur between multiple UEs; while in CFRA, network equipment can specify random access preamble for UEs to avoid Conflicts with the random access process of other UEs.
[0004]
It should be noted that the above introduction to the technical background is only set forth to facilitate a clear and complete description of the technical solutions of the present invention and to facilitate the understanding of those skilled in the art. It should not be considered that the above technical solutions are well-known to those skilled in the art just because these solutions are described in the background art part of the present invention.
[0005]
Summary of the invention
[0006]
In the research of the New Radio (NR, New Radio) system, at the Media Access Control (MAC, Media Access Control) layer, the random access (RA, Random Access) process may include the following steps: Step 1. Random process initiation; Step 2. Wireless channel quality based on the configured synchronization signal block (SSB, Synchronizing Signal Block) and/or Channel State Information Reference Signal (CSI-RS, Channel State Information Reference Signal) resources and whether there is a corresponding dedicated resource/preamble, etc. Factor, select an SSB or CSI-RS resource, or select an SSB at will; Step 3. Select and/or use the RA resource corresponding to the selected SSB or CSI-RS resource to send the corresponding SSB or CSI-RS resource Random access preamble; Step 4. For the UE that successfully receives the random access response (RAR, Random Access Response), in the case of CBRA, the RA is completed when the conflict is resolved, and when the conflict is not resolved, return to step 2 to reselect Resources and resend the random access preamble. In the case of CFRA, the RA is completed. For UEs that have not successfully received the RAR, return to step 2 to reselect resources and resend the random access preamble.
[0007]
Each time step 3 above is executed, the MAC layer will indicate to the lower layer the target received power corresponding to the random access preamble sent this time, so that the physical layer can calculate the corresponding random access preamble transmission power.
[0008]
In the case of retransmitting the random access preamble, due to the power boost mechanism, the target received power indicated by the MAC layer to the lower layer can be slowly increased, so that the uplink retransmission can be sent with the power equal to or slightly higher than the previous transmission. Not only is it conducive to successful reception on the network side, it will not cause too much interference to other UEs. Use the counter related to the power boost to determine whether the current transmission increases the target received power compared to the last transmission, that is, PREAMBLE_POWER_RAMPING_COUNTER.
[0009]
According to the current mechanism, from the perspective of resource selection, only when the selected SSB does not change, the counter related to the power increase will increase by 1, so that the target received power indicated to the lower layer will increase. In other cases, the counter remains unchanged.
[0010]
In addition, according to the current mechanism, when deciding whether to increase the counter related to power increase by 1, the MAC layer also needs to consider whether the counter suspension indication is received from the physical layer. When this instruction is received, the counter related to the power increase remains unchanged. Among them, if the UE changes the spatial transmission filter before the physical random access channel (PRACH, Physical Random Access Channel) retransmission, then the physical layer will notify the MAC layer to suspend the counter related to power increase, and the transmission counter suspension indication .
[0011]
Therefore, if the current mechanism is used to determine whether to increase the power, the following problems exist: the current mechanism only considers the selection of SSB, so whether it is the current random access resource selection process or the previous random access resource selection In the process, as long as the CSI-RS resource is selected, the power increase will not be triggered, so the current power when the random access preamble is sent is the same as before. In extreme cases, when the CSI-RS resource is selected every time the random access preamble is retransmitted, the power boost mechanism cannot be applied in the random access preamble retransmission process, which may lead to useless retransmissions and increase the UE It also causes the network side to fail to receive the random access preamble correctly, which reduces the success rate of random access.
[0012]
The embodiment of the present invention provides a method and device for determining power. According to the change of any one of the selected SSB and CSI-RS resources, it is determined whether to increase the target received power, so as to consider the selection of CSI-RS resources.

[0058]
Example 1
[0059]
The embodiment of the present invention provides a power determination method, which is applied to the user equipment side.
[0060]
FIG. 2 is a schematic diagram of a method for determining power in Embodiment 1 of the present invention. As shown in Figure 2, the method includes:
[0061]
Step 201: Determine whether to increase the target received power according to the change of any one of the selected synchronization signal block (SSB) and channel state information reference signal (CSI-RS) resources,
[0062]
Wherein, the selected SSB or CSI-RS resource is used to determine a random access (RA) resource, and the target received power is used to determine the transmission power of a random access preamble.
[0063]
In this way, according to the change of any one of the selected SSB and CSI-RS resources, it is determined whether to increase the target received power, so that the selection of CSI-RS resources is considered, and the power can be increased if necessary and unnecessary repetition can be avoided. Transmission, thereby improving the success rate of random access and reducing the power consumption of the UE.
[0064]
In this embodiment, the selected SSB or CSI-RS resource may be, for example, selecting an SSB based on the wireless channel quality of the configured SSB and/or CSI-RS resource and whether there is a corresponding dedicated resource/preamble and other factors. Or CSI-RS resources, or choose an SSB at will.
[0065]
In this embodiment, the purpose of selecting the SSB or CSI-RS resource is to determine the RA resource corresponding to the selected SSB or CSI-RS resource and the index of the random access preamble, and the user equipment can use the RA resource to send the index The indicated random access preamble.
[0066]
In this embodiment, the SSB or CSI-RS resource and the RA resource and the index of the random access preamble may have a mapping relationship. For example, the mapping relationship may be pre-configured to the user equipment on the network device side.
[0067]
In this embodiment, the target received power is used to determine the transmission power of the random access preamble, that is, the power at which the user equipment sends the random access preamble.
[0068]
For example, the user equipment uses the smaller value between the maximum power P CMAX,f,c (i) configured on the network equipment side and (target received power + path loss) to send the random access preamble. Wherein, the target received power can be notified by the MAC layer, and the path loss can be obtained by subtracting the reference signal received power (RSRP, Reference Signal Receiving Power) value after high-level filtering from the reference signal power provided by the system information.
[0069]
In this embodiment, the change of any one of the selected SSB and CSI-RS resources may include: the change of the type of the selected resource, and/or the change of the specific physical resource configured by the selected resource.
[0070]
In this embodiment, when determining the change of any one of the selected SSB and CSI-RS resources, the currently selected SSB or CSI-RS resource can be compared with the previous selection result, or it can be selected next. Compare the selected SSB or CSI-RS with all previous selection results.
[0071]
For example, the method may also include:
[0072]
Step 202: According to the comparison result between the currently selected SSB or CSI-RS resource and the previously selected SSB or CSI-RS resource, or according to the currently selected SSB or CSI-RS resource and the previously selected SSB and/or CSI-RS resource. The comparison result of the RS resources determines the change of any one of the selected SSB and CSI-RS resources.
[0073]
For example, according to the type of currently selected SSB or CSI-RS resource and the comparison result of the configured physical resource with the type of resource selected last time and the configured physical resource, or according to the type of currently selected SSB or CSI-RS resource And the comparison result of the configured physical resources with the types of all previously selected resources and the configured physical resources to determine the change of any of the selected SSB and CSI-RS resources.
[0074]
In this embodiment, the type of SSB or CSI-RS resource selected refers to whether SSB or CSI-RS resource is selected, that is, SSB and CSI-RS resources belong to different types of resources.
[0075]
In this embodiment, the configured physical resource refers to the physical resource specifically configured for the SSB or CSI-RS resource, for example, which frequency and/or which symbols or time slots are the physical resources configured for the selected SSB , Which frequency and/or which symbols or time slots are the physical resources configured by the selected CSI-RS resource.
[0076]
In this embodiment, to determine whether the physical resources configured by the SSB or CSI-RS resources are the same, the judgment can be made according to whether the SSB index or the CSI-RS resource ID is the same, that is, the SSB configurations of different indexes are different CSI-RS resources with different IDs are also configured with different physical resources.
[0077]
In this example, SSBs with different indexes are referred to as different SSBs, and CSI-RS resources with different IDs are referred to as different CSI-RS resources. In other words, different SSBs are configured with different physical resources, and different CSI-RS resources are also configured with different physical resources.
[0078]
The following will exemplify how to determine the change of any one of the selected SSB and CSI-RS resources according to the comparison result in step 202.
[0079]
First of all, the case where SSB is currently selected is explained.
[0080]
For example, if the current selection is SSB, the previous selection is SSB, and the two SSBs are the same, make sure that the selected SSB has not changed;
[0081]
For example, when SSB is currently selected, and the currently selected SSB is the same as one of all previously selected SSBs, it is determined that the selected SSB has not changed;
[0082]
For example, when the currently selected SSB is the CSI-RS resource selected last time, and the currently selected SSB is the same as the quasi-co-located SSB with the previously selected CSI-RS resource, it is determined that the selected SSB has not changed;
[0083]
For example, when the currently selected SSB is the same as the SSB that is quasi-colocated with one CSI-RS resource among all the previously selected CSI-RSs, it is determined that the selected SSB has not changed.
[0084]
For example, for the current selection of SSB, for other cases than the above example, it can be determined that the selected SSB has changed.
[0085]
Secondly, an explanation will be given on the case where the CSI-RS resource is currently selected.
[0086]
For example, when the CSI-RS resource is currently selected, the CSI-RS resource was selected last time, and the two CSI-RS resources are the same, it is determined that the selected CSI-RS resource has not changed;
[0087]
For example, when the currently selected CSI-RS resource is the same as one of all CSI-RS resources previously selected, it is determined that the selected CSI-RS has not changed;
[0088]
For example, when the CSI-RS resource is currently selected, the SSB resource selected last time, and the SSB quasi-colocated with the currently selected CSI-RS resource is the same as the previously selected SSB, it is determined that the selected CSI-RS resource is not change;
[0089]
For example, for the currently selected CSI-RS resource, for other cases than the above example, it can be determined that the selected CSI-RS resource has changed.
[0090]
In this embodiment, for some cases, when the quasi-colocation relationship between the CSI-RS resource and the SSB is considered or the quasi-colocation relationship is not considered, the result of determining whether the selected CSI-RS resource changes may be different.
[0091]
For example, the CSI-RS resource currently selected is the CSI-RS resource selected last time. The two CSI-RS resources are different, but the SSB that is quasi-colocated with the currently selected CSI-RS resource is the same as the previously selected CSI-RS resource. The CSI-RS resource quasi-co-location SSB is the same. When considering the quasi-co-location relationship between the CSI-RS resource and the SSB, it can be determined that the selected CSI-RS resource has not changed, or it can also be determined as the selected CSI-RS The resource has changed. When the quasi co-location relationship between the CSI-RS resource and the SSB is not considered, it can be determined that the selected CSI-RS resource has changed.
[0092]
For another example, the currently selected CSI-RS resource is different from all the previously selected CSI-RS resources. However, the currently selected CSI-RS resource quasi-colocated SSB and the previous At least one of the selected CSI-RS resources has the same quasi-co-located SSB. When the quasi-co-located relationship between CSI-RS resources and SSB is considered, it can be determined that the selected CSI-RS resources have not changed Or, it can also be determined that the selected CSI-RS resource has changed. When the quasi co-location relationship between the CSI-RS resource and the SSB is not considered, it can be determined that the selected CSI-RS resource has changed.
[0093]
In this embodiment, for the two cases mentioned above, when determining whether the selected CSI-RS resource changes, whether to consider the quasi-colocation relationship between the CSI-RS resource and the SSB, and whether to consider the quasi-colocation relationship The rules for determining the relationship may be pre-defined or pre-configured by the network device side.
[0094]
In the following, corresponding to the above step 202 and step 201, the specific manner of determining whether to increase the target received power according to the change of any one of the selected SSB and CSI-RS resources is exemplarily described.
[0095]
For example, in the case that any one of the selected SSB and CSI-RS resources has not changed, it is determined to increase the target received power.
[0096]
In this way, when the selected SSB or CSI-RS resources are not changed, the transmission power of the retransmitted random access preamble can be increased, and the power increase mechanism can be reasonably used to improve the success rate of random access.
[0097]
Below, an exemplary solution is given to determine the respective conditions for increasing the target received power and not increasing the target received power.
[0098]
For example, in solution 1) when the selected SSB is changed, it is determined not to increase the target received power; when the selected SSB is changed, it is determined to increase the target received power.
[0099]
In this way, a reasonable process can be performed for the situation that the CSI-RS resource is currently selected and has not changed, that is, the power is increased.
[0100]
For example, Solution 2) Determine to increase the target received power when any of the selected SSB and CSI-RS resources has not changed; except for the case where any of the selected SSB and CSI-RS resources has not changed In other cases, determine not to increase the target received power.
[0101]
In this way, for the current situation where the same resource is selected as before, for example, both SSB or CSI-RS resources are selected, reasonable processing can be performed.
[0102]
For example, solution 3) In the case where any one of the selected SSB and CSI-RS resources is changed, it is determined not to increase the target received power; except for the case where any one of the selected SSB and CSI-RS resources is changed In other cases, determine to increase the target received power.
[0103]
In this way, for the current situation where the same resource is selected as before, for example, both SSB or CSI-RS resources are selected, reasonable processing can be performed.
[0104]
For example, solution 4) When the selected SSB is changed or the SSB that is quasi-colocated with the selected CSI-RS resource is changed, it is determined not to increase the target received power; when the selected SSB is changed and the selected CSI-RS is changed In other cases other than the case where the resource quasi-co-located SSB changes, it is determined to increase the target received power.
[0105]
In this way, the quasi-co-location relationship between the CSI-RS resource and the SSB is considered, so that no matter what kind of resource is currently selected, reasonable processing can be performed. In this embodiment, for solution 2), for example, when the selected SSB type changes or the selected CSI-RS resource type changes, or the selected SSB or CSI-RS resource type does not In the case of a change but the selected physical resource changes, it is determined not to increase the target received power.
[0106]
In this embodiment, the type of SSB or CSI-RS resource selected refers to whether SSB or CSI-RS resource is selected, that is, SSB and CSI-RS resources belong to different types of resources. For example, if the SSB is currently selected, and the CSI-RS resource was selected last time, the type of the selected SSB has changed.
[0107]
In this embodiment, the configured physical resource refers to the physical resource specifically configured for the SSB or CSI-RS resource, for example, which frequency and/or which symbols or time slots are the physical resources configured for the selected SSB , Which frequency and/or which symbols or time slots are the physical resources configured by the selected CSI-RS resource. For example, the current selection is SSB, and the previous selection is also SSB, but the physical resources configured for the two selected SSBs are different, the selected SSB type does not change but the physical resource transmission changes.
[0108]
In this way, when the selected resource type changes or the selected resource type does not change but the physical resource changes, the power is not increased, which can reduce unnecessary power consumption of the user equipment.
[0109]
In step 201, determining whether to increase the target received power according to the change of any one of the selected SSB and CSI-RS resources. After determining whether the target received power is increased, the method may further include:
[0110]
Step 203: Determine whether the counter related to power increase increases by 1 according to whether the target received power is increased;
[0111]
Step 204: In the case of determining to increase the target received power, increase the counter related to the power increase by 1; and
[0112]
Step 205: If it is determined that the target received power is not to be increased, keep the counter related to the power increase unchanged.
[0113]
In steps 203-205, increasing the target received power can be achieved by various methods, for example, increasing the target received power can be achieved by adding 1 to a power-related counter. According to whether to increase the target received power, it is determined whether the counter related to the power increase is increased by 1, and the counter is increased by 1 according to the determined result or the counter is maintained unchanged.
[0114]
That is to say, according to whether to increase the target received power, maintain the counter related to the power increase to achieve the increase of the target received power or not. When the counter is increased by 1, the target received power is increased, and when the counter does not change , The target received power is not increased.
[0115]
In this embodiment, it may also be that in step 201, according to the change of any one of the selected SSB and CSI-RS resources, it is directly determined whether the power-related counter increases by 1. For example, it may be that any one of the selected SSB and CSI-RS resources changes, and the counter remains unchanged; otherwise, the counter is increased by 1.
[0116]
In other words, it can be determined whether the power-related counter is incremented by one according to the change of any one of the selected SSB and CSI-RS resources.
[0117]
In this embodiment, the counter related to power boosting may be a counter related to power boosting shared by SSB and CSI-RS resources, such as PREAMBLE_POWER_RAMPING_COUNTER; it may also be a counter related to power boosting dedicated to SSB, for example, PREAMBLE_POWER_RAMPING_COUNTER_SSB, And/or, a counter related to power boost dedicated to CSI-RS resources, for example, PREAMBLE_POWER_RAMPING_COUNTER_CSIRS. Which counter to use can be configured by the network device side.
[0118]
For example, in the case of determining to increase the target received power,
[0119]
When the counters related to power boost shared by SSB and CSI-RS resources are configured, add 1 to the counter related to power boost shared by SSB and CSI-RS resources.
[0120]
When the SSB-specific power boost-related counters and/or the CSI-RS resource-specific power boost-related counters are configured, if SSB is currently selected, the SSB-specific power boost-related counters Plus 1, when the CSI-RS resource is currently selected, the counter dedicated to the CSI-RS resource and related to power increase is increased by one.
[0121]
In this embodiment, through the above steps 203-205, the maintenance of the counter related to the power increase is completed. After that, the method may further include:
[0122]
Step 206: Calculate the target received power according to the product of the difference between the value of the counter related to the power boost and the preset value and the preset step length, the initial value of the target received power, and the preamble parameter.
[0123]
In step 206, the method for calculating the target received power may also be different according to the difference of the counters related to the power boost used by the user equipment.
[0124]
For example, in the case of using a counter related to power boost shared by SSB and CSI-RS resources, the target received power can be calculated according to the following formula (1):
[0125]
Target received power = preambleReceivedTargetPower+DELTA_PREAMBLE+
[0126]
(PREAMBLE_POWER_RAMPING_COUNTER–1)×preamblePowerRampingStep(1)
[0127]
Among them, preambleReceivedTargetPower represents the initial value of the target received power, DELTA_PREAMBLE represents the preamble parameter, PREAMBLE_POWER_RAMPING_COUNTER represents the value of the counter shared by the SSB and CSI-RS resources related to power boosting, 1 represents the preset value 1, and preamblePowerRampingStep represents the preset step length.
[0128]
In this embodiment, the initial value of the target received power, the preamble parameter, and the preset step size may be pre-configured on the network device side.
[0129]
For example, in the case of using SSB dedicated counters related to power boosting and/or CSI-RS resource dedicated counters related to power boosting, the target received power can be calculated according to the following formula (2):
[0130]
Target received power=preambleReceivedTargetPower+DELTA_PREAMBLE+(PREAMBLE_POWER_RAMPING_COUNTER_SSB+PREAMBLE_POWER_RAMPING_COUNTER_CSIRS–k)×preamblePowerRampingStep
[0131]
(2)
[0132]
Among them, preambleReceivedTargetPower represents the initial value of the target received power, DELTA_PREAMBLE represents the preamble parameter, PREAMBLE_POWER_RAMPING_COUNTER_SSB represents the value of the SSB dedicated power up-related counter, PREAMBLE_POWER_RAMPING_COUNTER_CSIRS represents the CSI-RS resource dedicated power up-related counter value, and k represents the value of the power up-related counter dedicated to the CSI-RS resource. Set the value to k, and preamblePowerRampingStep represents the preset step length.
[0133]
In this embodiment, the initial value of the target received power, the preamble parameter, and the preset step size may be pre-configured on the network device side.
[0134]
In this embodiment, when the network device is configured with SSB dedicated counters related to power boost and CSI-RS resource dedicated counters related to power boost, the user equipment can use these two counters or use one of them.
[0135]
In this embodiment, in the case of using SSB dedicated counters related to power boosting and/or counters dedicated to power boosting for CSI-RS resources, the preset value may be dedicated to power boosting according to the resources used. The number of related counters, the initial value of the SSB dedicated power boost-related counter, and/or the initial value of the CSI-RS resource dedicated power boost-related counter are determined.
[0136]
For example, some exemplary situations are listed below.
[0137]
1) Only the SSB dedicated counter related to power boosting is used, and the initial value of the counter is 1, then the preset value is 1;
[0138]
2) Only the counter related to power boost dedicated to CS-RS resources is used, and the initial value of the counter is 1, then the preset value is 1;
[0139]
3) SSB dedicated counters related to power boosting are used, and counters dedicated to power boosting of CS-RS resources are also used, and the initial values ​​of the two counters are both 1, then the preset value is 2;
[0140]
4) Only the SSB dedicated counter related to power boost is used, and the initial value of the counter is 0, then the preset value is 0;
[0141]
5) Only a counter related to power boost dedicated to CS-RS resources is used, and the initial value of the counter is 0, then the preset value is 0;
[0142]
6) The SSB dedicated counter related to power boosting is used, and the CS-RS resource dedicated counter related to power boosting is also used, and the initial values ​​of the two counters are both 0, then the preset value is 0;
[0143]
7) The SSB dedicated counter related to power boost is used, and the initial value of the counter is 0; the CS-RS resource dedicated counter related to power boost is also used, and the initial value of the counter is 1, then the The default value is 1;
[0144]
8) The SSB dedicated counter related to power boost is used, and the initial value of the counter is 1; the CS-RS resource dedicated counter related to power boost is also used, and the initial value of the counter is 0, then The default value is 1.
[0145]
In step 206, the parameters shared by the SSB and CSI-RS resources, or the parameters dedicated to the SSB or CSI-RS resources may also be used to calculate the target received power.
[0146]
For example, according to the difference between the value of the counter related to power boost and the preset value, the product of the preset step size dedicated to SSB or CSI-RS resource or both, SSB or CSI-RS resource dedicated or both can be used The initial value of the target received power and the preamble parameters dedicated to SSB or CSI-RS resources or both are used to calculate the target received power.
[0147]
For example, regardless of whether the SSB or CSI-RS resource is currently selected, the target received power is calculated according to the above formula (1).
[0148]
For another example, the target received power is calculated using parameters dedicated to the currently selected resource.
[0149]
For example, when SSB is currently selected, the following formula (3) can be used to calculate the target received power:
[0150]
Target received power =
[0151]
preambleReceivedTargetPower_SSB+DELTA_PREAMBLE_SSB+(PREAMBLE_POWER_RAMPING_COUNTER–1)×preamblePowerRampingStep_SSB
[0152]
(3)
[0153]
Among them, preambleReceivedTargetPower_SSB represents the initial value of the target received power dedicated to SSB, DELTA_PREAMBLE_SSB represents the preamble parameter dedicated to SSB, PREAMBLE_POWER_RAMPING_COUNTER represents the value of the counter related to power boosting, 1 represents the preset value 1, and preamblePowerRampingStep_SSB represents the preset step size dedicated to SSB .
[0154]
In this embodiment, the initial value of the SSB dedicated target received power, the preamble parameter, and the preset step size may be pre-configured on the network device side.
[0155]
For example, in the case that CSI-RS is currently selected, the following formula (4) can be used to calculate the target received power:
[0156]
Target received power =
[0157]
preambleReceivedTargetPower_CSIRS+DELTA_PREAMBLE_CSIRS+(PREAMBLE_POWER_RAMPING_COUNTER–1)×preamblePowerRampingStep_CSIRS
[0158]
(4)
[0159]
Among them, preambleReceivedTargetPower_CSIRS represents the initial value of target received power dedicated to CSI-RS resources, DELTA_PREAMBLE_CSIRS represents the preamble parameter dedicated to CSI-RS resources, PREAMBLE_POWER_RAMPING_COUNTER represents the value of the counter related to power boosting, 1 represents the preset value 1, and preamblePowerRampingStep_CSIRS represents CSI -Preset step size dedicated to RS resources.
[0160]
In this embodiment, the initial value of the target received power dedicated to the CSI-RS resource, the preamble parameter, and the preset step size may be pre-configured on the network device side.
[0161]
In this embodiment, the above steps 202-206 are optional steps.
[0162]
FIG. 3 is another schematic diagram of the method for determining power in Embodiment 1 of the present invention. As shown in Figure 3, the method includes:
[0163]
Step 301: Determine whether to send the hang-up indication of the counter related to the power increase according to whether the spatial transmission filter is changed;
[0164]
Step 302: Determine whether to increase the target received power according to the change of any one of the selected SSB and CSI-RS resources and whether the suspension indication of the counter related to the power increase is received.
[0165]
In step 301, when the physical layer changes the spatial domain transmission filter, it sends a suspension instruction of the counter related to the power boost to the MAC layer. When the physical layer does not change the spatial domain transmission filter, the suspension instruction is not sent.
[0166]
In step 302, when the MAC layer receives the suspend indication, it keeps the counter related to the power increase unchanged, that is, does not increase the target received power. When the MAC layer does not receive the suspend indication, according to the selected SSB Determine whether to increase the target received power according to the change of any one of the CSI-RS resources. The specific determination method is the same as that of step 201 in FIG. 2 and will not be repeated here.
[0167]
In this embodiment, the method may further include:
[0168]
Step 303: Determine whether to change the spatial transmission filter according to the selected SSB or CSI-RS resource, or according to the random access resource corresponding to the selected SSB or CSI-RS resource and the index of the random access preamble.
[0169]
In this embodiment, step 303 is an optional step.
[0170]
For example, in the case of random access preamble retransmission, or in the case of random access preamble initial transmission or retransmission, and before the MAC layer starts to perform the random access preamble transmission process, the MAC layer will The index of the selected SSB or the ID of the selected CSI-RS resource or the index of the SSB quasi-colocated with the selected CSI-RS resource is sent to the physical layer, or the MAC layer sends the selected SSB or CSI-RS resource to the physical layer The random access resource and the index of the random access preamble are sent to the physical layer.
[0171]
In addition, if the MAC layer has completed the random access preamble transmission process, it may no longer provide the above information to the physical layer and only provide the target received power. In addition, if there is an RA-RNTI, this information is also provided.
[0172]
In this way, the following problem in the prior art can be solved: when there is reciprocity between the uplink wireless status and the downlink wireless status, the spatial transmission filter is associated with the resource selected by the MAC layer. Based on the current interaction between the physical layer and the MAC layer, the physical layer does not know the result of MAC layer resource selection when determining the spatial transmission filter. This may cause the physical layer to erroneously provide a suspend indication for the MAC layer, or erroneously fail to provide a suspend indication for the MAC layer, resulting in a wrong decision on whether to increase power.
[0173]
In other words, it is possible to provide a suspend indication for the MAC layer reasonably, so as to reasonably decide whether to increase the power.
[0174]
It can be seen from the above embodiment that according to the change of any one of the selected SSB and CSI-RS resources, it is determined whether to increase the target received power, thus considering the selection of CSI-RS resources, the power can be increased and combined if necessary Useless retransmissions are avoided, thereby improving the success rate of random access and reducing UE power consumption.

[0179]
Step 402: Determine to increase the target received power when the selected SSB is changed.
[0180]
In this embodiment, when determining whether the selected CSI-RS resource changes, the quasi-co-location relationship between the CSI-RS resource and the SSB is not considered.
[0181]

[0187]

[0189]
It can be seen from the above embodiment that according to the change of any one of the selected SSB and CSI-RS resources, it is determined whether to increase the target received power, thus considering the selection of CSI-RS resources, the power can be increased and combined if necessary Useless retransmissions are avoided, thereby improving the success rate of random access and reducing UE power consumption. In addition, a reasonable process can be performed for the situation that the CSI-RS resource is currently selected and has not changed, that is, the power is increased.

[0193]
Step 501: In the case that any one of the selected SSB and CSI-RS resources has not changed, determine to increase the target received power;
[0194]
Step 502: In other cases than the case where any one of the selected SSB and CSI-RS resources has not changed, it is determined not to increase the target received power.
[0195]
In this embodiment, when determining whether the selected CSI-RS resource changes, the quasi-co-location relationship between the CSI-RS resource and the SSB is not considered.
[0196]
In this embodiment, for the case where any one of the selected SSB and CSI-RS resources is not changed, please refer to the description in Embodiment 1.
[0197]
For example, the case where any one of the selected SSB and CSI-RS resources has not changed may include any of the following cases:
[0198]
1) SSB is currently selected, SSB was selected last time, and the two are the same;
[0199]

[0205]
Hereinafter, the method of this embodiment will be exemplarily described for the switching scenario.
[0206]
In the case of handover, the network device may only provide dedicated random access resources and random access preambles corresponding to the CSI-RS resources for the user equipment. In this case, CSI-RS resources that meet the radio link quality conditions will be selected preferentially. In this way, in all resource selection processes, only CSI-RS resources will be selected, and it is a normal situation not to select SSB.
[0207]
For example, during the initial transmission of the random access preamble, the CSI-RS resource with CSI-RS resource ID=3 is selected. In the first random access preamble retransmission, the CSI-RS resource with CSI-RS resource ID=4 is selected, and the power-related counter remains unchanged. In the second random access preamble retransmission, the CSI-RS resource with CSI-RS resource ID=3 is selected. If only compared with the previous transmission, the power-related counter remains unchanged; if all transmissions are considered , The power-related counter increases by 1.
[0208]
In addition, in the case of handover, during a certain resource selection, if all CSI-RS resources configured with dedicated random access resources do not meet the radio link quality conditions, then the public random access corresponding to the SSB can be selected The resource performs random access preamble retransmission.
[0209]
For example, during the initial transmission of the random access preamble, the CSI-RS with CSI-RS resource ID=3 is selected. In the first random access preamble retransmission, the CSI-RS with CSI-RS resource ID=4 is selected, and the power-related counter remains unchanged. In the second random access preamble retransmission, the SSB with SSB index=1 is selected, and the power-related counter remains unchanged.
[0210]
It can be seen from the above embodiment that according to the change of any one of the selected SSB and CSI-RS resources, it is determined whether to increase the target received power, thus considering the selection of CSI-RS resources, the power can be increased and combined if necessary Useless retransmissions are avoided, thereby improving the success rate of random access and reducing UE power consumption. In addition, for the current situation where the same resource is selected as before, for example, both SSB or CSI-RS resources are selected, reasonable processing can be performed.

[0222]
4) The currently selected CSI-RS resource is different, and the currently selected CSI-RS resource is different from all the previously selected CSI-RS resources.
[0223]
In this embodiment, the method for increasing the target received power and not increasing the target received power can be the same as that described in Embodiment 1, that is, according to whether the target received power is increased, it is determined whether the counter related to the power increase is increased by 1, and According to the determined result, the counter is increased by 1 or the counter is kept unchanged.
[0224]
In addition, the specific method of using which counter or parameter to calculate the target received power can be the same as that described in Embodiment 1, and will not be repeated here.

[0226]
Hereinafter, the method of this embodiment will be exemplarily described for the switching scenario.
[0227]
In the case of handover, the network device may only provide dedicated random access resources and random access preambles corresponding to the CSI-RS resources for the user equipment. In this case, CSI-RS resources that meet the radio link quality conditions will be preferentially selected. In this way, in all resource selection processes, only CSI-RS resources are selected, and it is normal that no SSB is selected.
[0228]
When the random access preamble is initially transmitted, the CSI-RS resource with CSI-RS resource ID=3 is selected. In the first random access preamble retransmission, the CSI-RS resource with CSI-RS resource ID=4 is selected, and the power-related counter remains unchanged. In the second random access preamble retransmission, the CSI-RS resource with CSI-RS resource ID=3 is selected. If only compared with the previous transmission, the power-related counter remains unchanged; if all For transmission, the power-related counter is incremented by 1.
[0229]
In addition, in the case of handover, in a certain resource selection, if all CSI-RS configured with dedicated random access resources do not meet the radio link quality conditions, then the public random access resources corresponding to the SSB can be selected for Retransmission of the random access preamble.
[0230]
For example, during the initial transmission of the random access preamble, the CSI-RS resource with CSI-RS resource ID=3 is selected. In the first random access preamble retransmission, the CSI-RS resource with CSI-RS resource ID=4 is selected, and the power-related counter remains unchanged. In the second random access preamble retransmission, the SSB with SSB index=1 is selected, and the power-related counter is incremented by 1.
[0231]
It can be seen from the above embodiment that according to the change of any one of the selected SSB and CSI-RS resources, it is determined whether to increase the target received power, thus considering the selection of CSI-RS resources, the power can be increased and combined if necessary Useless retransmissions are avoided, thereby improving the success rate of random access and reducing UE power consumption. In addition, for the current situation where the same resource is selected as before, for example, both SSB or CSI-RS resources are selected, reasonable processing can be performed.

[0256]
In step 702, for example, in the case where the currently selected SSB is the same as the previously selected SSB, or in the case where the currently selected SSB is the same as at least one of all the previously selected SSBs, or in the case where the currently selected SSB is the same When the SSB is the same as the SSB that is quasi-colocated with the previously selected CSI-RS resource, or when the currently selected SSB is the same as at least one of the SSBs that are quasi-colocated with all the previously selected CSI-RS resources Or, when the currently selected CSI-RS resource is the same as the previously selected CSI-RS resource, or, at least one of the currently selected CSI-RS resource and all the previously selected CSI-RS resources are the same In the case, or, the currently selected CSI-RS resource is different from the previously selected CSI-RS resource and the SSB that is quasi-colocated with the currently selected CSI-RS resource is quasi-co-located with the previously selected CSI-RS resource When the configured SSB is the same, or, the currently selected CSI-RS resource is different from all the previously selected CSI-RS resources, and the SSB that is quasi-colocated with the currently selected CSI-RS resource is the same as all the previously selected CSI-RS resources.

[0257]
In this embodiment, the method for increasing the target received power and not increasing the target received power can be the same as that described in Embodiment 1, that is, according to whether the target received power is increased, it is determined whether the counter related to the power increase is increased by 1, and According to the determined result, the counter is increased by 1 or the counter is kept unchanged.
[0258]
In addition, the specific method of using which counter or parameter to calculate the target received power can be the same as that described in Embodiment 1, and will not be repeated here.
[0259]
In addition, the method of this embodiment may also include determining the suspension indication of the counter, and determining whether to increase the target received power according to the change of any one of the selected SSB and CSI-RS resources and whether the suspension indication is received, The specific implementation method is the same as that described in Embodiment 1, and will not be repeated here.
[0260]
Hereinafter, the method of this embodiment will be exemplarily described in a scenario where the random access process is triggered due to beam failure recovery.
[0261]
When the random access process is triggered due to beam failure recovery, the network device may configure both CSI-RS and SSB dedicated random access resources for beam failure recovery, and also configure some or all of the CSI-RS resources Quasi-co-located SSB.
[0262]
For example, when the random access preamble is first transmitted, the MAC layer selects the random access resource corresponding to the SSB with SSB index=1; when the random access preamble is retransmitted for the first time, the MAC sublayer selects CSI-RS The CSI-RS resource with resource ID=3 (which is quasi-colocated with the SSB with SSB index=1) can be considered that the selected CSI-RS resource has not changed, and the counter related to power increase is increased by 1.
[0263]
It can be seen from the above embodiment that according to the change of any one of the selected SSB and CSI-RS resources, it is determined whether to increase the target received power, thus considering the selection of CSI-RS resources, the power can be increased and combined if necessary Useless retransmissions are avoided, thereby improving the success rate of random access and reducing UE power consumption. In addition, since the quasi-co-location relationship between CSI-RS resources and SSB is considered, reasonable processing can be performed no matter what kind of resource is currently selected.

Example 6
[0265]
The embodiment of the present invention also provides a power determination method, which is applied to the network equipment side, and corresponds to the power determination method applied to the user equipment side in Embodiments 1-5.
[0266]
FIG. 8 is a schematic diagram of a method for determining power according to Embodiment 6 of the present invention. As shown in Figure 8, the method includes:
[0267]
Step 801: Configure the user equipment with a counter related to power boost shared by SSB and CSI-RS resources, or a counter related to power boost dedicated to SSB and a counter related to power boost dedicated to CSI-RS resources; and/or
[0268]
Step 802: Configure the user equipment with parameters shared by the SSB and CSI-RS resources for calculating the target received power, or parameters dedicated to the SSB and CSI-RS resources for calculating the target received power.
[0269]
For example, the SSB-specific parameters used to calculate the target received power include at least one of the following parameters: SSB-specific preset step size, SSB-specific target received power initial value, and SSB-specific preamble parameters,
[0270]
The CSI-RS resource-specific parameters used to calculate the target received power include at least one of the following parameters: a preset step size dedicated to CSI-RS resources, a target received power initial value dedicated to CSI-RS resources, and CSI-RS resource dedicated The preamble parameter.
[0271]
In this embodiment, the network device configures the counter related to power increase and/or the parameter for calculating the target received power to the user equipment according to the above steps, so that the user equipment can use the relevant counter and parameter to calculate the target according to the configuration. For the specific calculation method of the received power, refer to the record in Embodiment 1, which will not be repeated here.
[0272]
In this embodiment, for example, the method may further include:
[0273]
Step 803: Configure to the user equipment a rule whether to consider the quasi-co-location relationship between the CSI-RS resource and the SSB when determining whether the selected CSI-RS resource is changed; and/or

Step 804: Configure a rule for determining whether the selected CSI-RS resource is changed and/or the relationship between the CSI-RS resource and the SSB quasi-co-location in consideration of the relationship between the CSI-RS resource and the SSB quasi-co-location.
[0275]
For example, the currently selected CSI-RS resource is also the CSI-RS resource selected last time. The two CSI-RS resources are different, but the SSB that is quasi-colocated with the currently selected CSI-RS resource is the same as the previously selected CSI-RS resource. The CSI-RS resource quasi-co-location SSB is the same. When considering the quasi-co-location relationship between the CSI-RS resource and the SSB, it can be determined that the selected CSI-RS resource has not changed, or it can also be determined as the selected CSI-RS The resource has changed, and determining whether it has changed is regulated by the configuration rule; when the quasi-co-location relationship between the CSI-RS resource and the SSB is not considered, it can be determined that the selected CSI-RS resource has changed.
[0276]
For another example, the currently selected CSI-RS resource is different from all the previously selected CSI-RS resources. However, the currently selected CSI-RS resource quasi-colocated SSB and the previous At least one of the selected CSI-RS resources has the same quasi-co-located SSB. When the quasi-co-located relationship between CSI-RS resources and SSB is considered, it can be determined that the selected CSI-RS resources have not changed Or, it can also be determined that the selected CSI-RS resource has changed, and the determination of whether the change has occurred is regulated by the configuration rule; when the quasi-co-location relationship between the CSI-RS resource and the SSB is not considered, it can be determined as The selected CSI-RS resource has changed.
[0277]
In this embodiment, the quasi-co-location relationship can be configured through RRC dedicated signaling.
[0278]
In addition, the quasi-co-location relationship can be configured through measurement object configuration, and/or the quasi-co-location relationship can be configured together with the candidate beam.
[0279]
In this embodiment, the relationship between the CSI-RS resources and the SSB quasi-co-location may include: CSI-RS resources and any SSB quasi-co-location; or, CSI-RS resources and all SSBs are not quasi-co-location Relationship; or, the CSI-RS resource is quasi-colocated with at least one predefined or pre-configured SSB.
[0280]
In this embodiment, the execution order of the above steps 801-804 is not limited.
[0281]
It can be seen from the foregoing embodiment that by configuring the user equipment with SSB and/or CSI-RS resource-related counters related to power increase and/or parameters for calculating target received power, the user equipment can be configured according to the configuration and according to The change of any one of the selected SSB and CSI-RS resources determines whether to increase the target received power, thus considering the selection of CSI-RS resources, the power can be increased if necessary and unnecessary retransmissions can be avoided, thereby The success rate of random access is improved and the power consumption of the UE is reduced.

Example 10
[0346]
An embodiment of the present invention also provides a user equipment, and the user equipment includes the power determining apparatus as described in Embodiment 8.
[0347]
FIG. 14 is a schematic block diagram of the system configuration of user equipment according to Embodiment 10 of the present invention. As shown in FIG. 14, the user equipment 1400 may include a processor 1410 and a memory 1420; the memory 1420 is coupled to the processor 1410. It is worth noting that this figure is exemplary; other types of structures can also be used to supplement or replace this structure to implement telecommunication functions or other functions.
[0348]
In one embodiment, the function of the power determination device may be integrated into the processor 1410. Wherein, the processor 1410 may be configured to determine whether to increase the target received power according to changes in any one of the selected synchronization signal block (SSB) and channel state information reference signal (CSI-RS) resources. The SSB or CSI-RS resource is used to determine a random access (RA) resource, and the target received power is used to determine the transmission power of a random access preamble.
[0349]
For example, in the case that any one of the selected SSB and CSI-RS resources has not changed, it is determined to increase the target received power.
[0350]
For example, in a case where the selected SSB changes, it is determined not to increase the target received power; in other cases than the selected SSB changes, it is determined to increase the target received power.
[0351]
For example, in the case that any one of the selected SSB and CSI-RS resources does not change, it is determined to increase the target received power; except for the case where any one of the selected SSB and CSI-RS resources does not change In other cases, it is determined not to increase the target received power.

For example, in the case where any one of the selected SSB and CSI-RS resources is changed, it is determined not to increase the target received power; other than the case where any one of the selected SSB and CSI-RS resources is changed In this case, it is determined to increase the target received power.
[0353]
For example, in the case where the selected SSB changes or the SSB quasi-colocated with the selected CSI-RS resource changes, it is determined not to increase the target received power; when the selected SSB changes and the selected CSI-RS resource changes In other cases than the case where the quasi-co-located SSB is changed, it is determined to increase the target received power.
[0354]
For example, the processor 1410 may be further configured to: in the case of determining to increase the target received power, increase a counter related to power increase shared by the SSB and CSI-RS resources by 1, or increase the SSB dedicated power to the power increase counter. The related counter or the CSI-RS resource dedicated counter related to power increase is incremented by 1.

For example, the power determining device can be configured as a chip connected to the processor 1410, and the function of the power determining device can be realized through the control of the processor 1410. .

As shown in FIG. 14, the user equipment 1400 may further include: a communication module 1430, an input unit 1440, a display 1450, and a power supply 1460. It is worth noting that the user equipment 1400 does not necessarily include all the components shown in FIG. 14; in addition, the user equipment 1400 may also include components not shown in FIG. 14, and reference may be made to related technologies.
[0358]
As shown in FIG. 14, the processor 1410 is sometimes called a controller or an operating control, and may include a microprocessor or other processor devices and/or logic devices. The processor 1410 receives input and controls the operation of various components of the user equipment 1400. operating.
[0359]
Wherein, the memory 1420 may be, for example, one or more of a cache, a flash memory, a hard drive, a removable medium, a volatile memory, a non-volatile memory, or other suitable devices. A variety of data can be stored, and programs that execute related information can also be stored. And the processor 1410 can execute the program stored in the memory 1420 to implement information storage or processing. The functions of other components are similar to the existing ones, so I won't repeat them here. Each component of the user equipment 1400 may be implemented by dedicated hardware, firmware, software, or a combination thereof, without departing from the scope of the present invention.
[0360]
It can be seen from the above embodiment that according to the change of any one of the selected SSB and CSI-RS resources, it is determined whether to increase the target received power, thus considering the selection of CSI-RS resources, the power can be increased and combined if necessary Useless retransmissions are avoided, thereby improving the success rate of random access and reducing UE power consumption.
