[0002]
Paging can help the network find the terminals in the idle state (RRC_IDLE state) and the inactive state (RRC_INACTIVE state), and notify the system information of the terminals in the idle state, inactive state and connected state (RRC_CONNECTED state), SI) updates and the transmission of information from the Public Warning System (PWS).
[0003]
Figure 1 shows the process of a network device initiating a paging. As shown in Figure 1, the network device initiates a paging process by sending a paging message at the paging moment (Paging Occasion, PO) of the terminal device. In each Discontinuous Reception (DRX, Discontinuous Reception) cycle, the terminal device in the idle state or in the inactive state only monitors paging at one paging moment; while the terminal device in the connected state can be paged at any time notified by the system information Monitor paging at all times.
[0004]
Figure 2 is a schematic diagram of the paging moment on the New Radio (NR, New Radio) authorized frequency band. As shown in Figure 2, according to the system frame number (SFN, System Frame Number) of the paging frame (PF, Paging Frame) in NR and PO index calculation formula, some terminal devices can monitor paging messages on PO1, and some terminal devices can monitor paging messages on PO2.
[0005]
On the other hand, the issue of frequency resources is one of the important topics in the discussion of communication technology. In order to solve the problem of frequency resources, in addition to improving resource utilization, the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) also tried to use more frequency bands, including the use of unlicensed frequency bands, such as NR based on unlicensed frequency bands. Access (NR based access to unlicensed spectrum, NR-U) mechanism.
[0006]
For NR-U, there are the following deployment scenarios:
[0007]
Scenario A: Carrier Aggregation (CA, Carrier Aggregation) between NR and NR-U on the licensed frequency band;
[0008]
Scenario B: Dual Connectivity (DC, Dual Connectivity) between Long Term Evolution (LTE) and NR-U on the licensed frequency band;
[0009]
Scenario C: Independent NR-U;
[0010]
Scenario D: An NR cell where the downlink is on an unlicensed frequency band and the uplink is on a licensed frequency band;
[0011]
Scenario E: Dual connection between NR and NR-U on the licensed frequency band.
[0012]
It should be noted that the above introduction to the technical background is only for the convenience of a clear and complete description of the technical solution of the present invention, and to facilitate the understanding of those skilled in the art.

Summary of the invention
[0014]
When using unlicensed frequency bands to provide services to the terminal, the network equipment and terminal equipment need to monitor the channel before communicating, that is, through listening before talk (LBT, Listen Before Talk) or clear channel assessment (CCA, Clear Channel Assessment) Mechanism to determine whether the channel is free.

Various embodiments of the present invention will be described below with reference to the accompanying drawings. These embodiments are only exemplary, and are not limitations to the present invention.
[0122]
Example 1
[0123]
This embodiment provides a method for configuring and determining paging opportunities. The method is applied to network equipment and is applied to an unlicensed frequency band (NR-U) based on new wireless. The method reuses current parameters without introducing new parameters. To increase the total paging time. Fig. 4 is a schematic diagram of the configuration and the method for determining a paging opportunity in this embodiment. Please refer to Fig. 4, the method includes:
[0124]
Step 401: The network device generates first configuration information, the first configuration information includes a first parameter associated with a paging moment, and the number of paging moments associated with the first parameter is greater than 4 and is an integer multiple of 4. ；
[0125]
Step 402: The network device sends the first configuration information to a terminal device.
[0126]
This embodiment does not limit the manner of generating the above-mentioned first configuration information.
[0127]
In this embodiment, the above-mentioned first parameter is the parameter used in the current standard. The difference from the current standard is that the number of paging moments associated with this parameter is greater than 4 and is an integer multiple of 4. Therefore, through reuse The current standard parameter and the modification of the parameter value increase the paging moment.
[0128]
In this embodiment, the above-mentioned first parameter may include at least one of the following: a parameter indicating the number of paging moments associated with a paging frame; and a first downlink control channel (PDCCH) monitoring moment (monitoring time) indicating the paging moment. occasion) parameters.
[0129]
The above-mentioned "parameter indicating the number of paging moments associated with a paging frame" is, for example, the parameter "ns" in the current standard, and the value of the parameter may be an integer multiple of 4 such as 8, 16, etc. Among them, the paging moment associated with the paging frame may be in the paging frame or not in the paging frame, but in the next radio frame of the paging frame, or the designated radio frame after the paging frame , Or in the next paging frame after the paging frame.
[0130]
The above “parameter representing the first PDCCH monitoring moment at the paging moment” is, for example, the parameter “firstPDCCH-MonitoringOccasionOfPO” in the current standard, and the size of the value included therein can be expanded to an integer greater than 4, such as 8. 16 is an integer multiple of 4. Among them, one paging moment can have one parameter value or multiple parameter values.
[0131]
In this embodiment, after paging moments are added, these paging moments can be used to page a specific terminal device. When the paging moment of the terminal device is more than one, the network device can also configure the terminal device to determine its own The parameter of the index of the paging moment (Y).
[0132]
For example, the network device may send third configuration information to the terminal device. The third configuration information includes the maximum number (Y) of paging moments that the terminal device can monitor. The maximum number can be used as the above-mentioned parameter. The first parameter and the maximum number to determine the index of the own paging moment will be specifically described in Embodiment 2.
[0133]
This embodiment also provides a method for configuring and determining a paging opportunity, which is applied to network equipment and applied to an unlicensed frequency band (NR-U) based on new wireless. Different from the method of reusing current parameters without introducing new parameters in the embodiment shown in FIG. 4, this embodiment also introduces a scale factor on the basis of reusing the current parameters.
[0134]
Fig. 5 is a schematic diagram of the method for configuring and determining a paging opportunity of this embodiment. As shown in Fig. 5, the method includes:
[0135]
Step 501: The network device generates first configuration information, the first configuration information includes a first parameter associated with a paging moment, and the number of paging moments associated with the first parameter is 1, 2 or 4;
[0136]
Step 502: The network device sends the first configuration information to the terminal device, where the number of paging moments configured by the network device is at least determined by the first parameter and the first ratio configured by the network device, or The second ratio determined by the terminal device is determined.
[0137]
In this embodiment, the above-mentioned first parameter is the parameter used in the current standard. In this embodiment, the current parameter and the current possible configuration of the parameter can be reused. For example, the number of associated paging moments can still be 1. , 2 or 4. Different from the current standard, this embodiment also introduces a scale factor, such as the above-mentioned first scale or second scale. The first parameter and the scale factor are used to determine the number of paging moments configured by the network device, for example, The number of paging moments associated with the first parameter is multiplied by the scale factor to obtain the number of paging moments configured by the network device.
[0138]
In this embodiment, the scale factor may be cell-specific or terminal device-specific, and its value may be an integer greater than 1, such as 2, 4, and so on.
[0139]
In an implementation of this embodiment, the scale factor is configured by the network device. For example, the network device may also send second configuration information to the terminal device. The second configuration information includes the scale factor (referred to as the first Ratio). Therefore, the number of the above-mentioned paging moments configured by the network device is determined by at least the above-mentioned first parameter and the first ratio.
[0140]
In this embodiment, the above-mentioned second configuration information may be downlink information carrying discovery reference signals (Discovery Reference Signal, DRS) or system information blocks (for example, the first system information block (SIB1)), etc., thus, the above-mentioned second configuration information A ratio can be explicitly configured by the network equipment and included in the downlink transmission such as DRS or SIB1.
[0141]
In this embodiment, the above-mentioned second configuration information may also be related information based on the SSB. Therefore, the above-mentioned first ratio may be implicitly indicated by the network device.
[0142]
In another implementation of this embodiment, the scale factor is determined by the terminal device. For example, the terminal device may determine the scale factor (referred to as the second scale) based on interference-related measurement results or load-related measurement results. . Therefore, the number of the paging moments configured by the network device is determined by at least the first parameter and the second ratio.
[0143]
For example, the terminal device may be based on at least one of channel occupancy ratio (CR), channel busy ratio (CBR), and success or failure rate or frequency ratio of channel detection (LBT or CCA, etc.) To determine the second ratio.
[0144]
The above-mentioned channel occupancy rate refers to the ratio between the number of transmitted or authorized resources (for example, the number of subchannels) and the total number of resources configured in the transmission pool within a period of time (for example, the time of 1000 subframes before and after the current subframe). The above-mentioned channel busy rate is similar to the channel busy rate in device-to-device (D2D) communication. It can be measured by measuring a certain measurement quantity (such as RSSI) of the resources in the configured transmission pool, and the resources whose result is higher than the threshold 1 can be accounted for. The ratio of the total configured resources is used as the channel busy rate, and the threshold 1 may be defined in the standard or configured by the network device. The success or failure rate of channel detection is no longer explained. The ratio of the number of successes or failures of channel detection may be the ratio of the number of channels considered to be idle or busy (or performing/not transmitting) after the channel detection is passed to the total number of channel detections.
[0145]
In this embodiment, after paging moments are added, these paging moments can be used to page a specific terminal device. When the paging moment of the terminal device is more than one, the network device can also configure the terminal device to determine its own The parameter of the index of the paging moment (Y).
[0146]
For example, the network device may send third configuration information to the terminal device, where the third configuration information includes the parameter Y, and the terminal device uses the first parameter and the parameter Y to determine its own paging moment index, The details will be described in Embodiment 2.
[0147]
In this embodiment, the aforementioned parameter Y may be the maximum number (Y) of paging moments that the terminal device can monitor. In addition, the above-mentioned first ratio may also be used as the parameter, that is, when the above-mentioned first ratio is the maximum number (Y) of paging moments that the terminal device can monitor, the third configuration information may be omitted.
[0148]
Fig. 6 is an example of a paging moment in a DRX cycle. As shown in Fig. 6, the method of this embodiment increases the total paging opportunity.
[0149]
Through the method of this embodiment, by supporting one paging frame to have more paging moments, the total paging moment is increased. Using the method of this embodiment, the number of terminal devices that are paged at the same paging moment is reduced. In this way, when a paging moment fails to send or monitor a paging message due to a channel detection failure, the number of affected terminal devices is reduced. To a certain extent, it alleviates the situation that the channel detection fails and the terminal device cannot be paged due to the failure to send or monitor the paging message.
[0150]
In addition, the method of this embodiment can reuse the current paging mechanism to the greatest extent, including the calculation of the system frame number (SFN) and the paging moment (PO) index of the paging frame on the terminal device side, parameter configuration, etc., which is compatible with current standards and products. The realization impact is small, thereby saving costs.

In an embodiment, the parameter Y may be the maximum number (Y) of paging moments that the terminal device can monitor, and the terminal device may use the first parameter and the maximum number (Y) to determine its own paging moment. index.
[0164]
In an embodiment, the above-mentioned first ratio may be the maximum number (Y) of paging moments that the terminal device can monitor. Therefore, the terminal device can use the first parameter and the maximum number (Y) to determine its own The index of the paging time. In this embodiment, the above-mentioned third configuration information can be omitted.
[0165]
In this embodiment, the index of the paging moment of the terminal device is at least one, and when the index of the paging moment of the terminal device is at least two, the index of the paging moment of the terminal device may be in the time domain. Discrete or centralized.
[0166]
In an embodiment, the terminal device can determine its own paging moment index according to the following formula:
[0167]
i_s mod(ns/Y)=floor(UE_ID/N)mod(ns/Y)
[0168]

[0169]
In this embodiment, the index i_s of the current PO is reused, but the formula for determining i_s is updated, so that different paging moments belonging to the same terminal device are discrete.
[0170]
In another embodiment, the terminal device can determine its own paging moment index according to the following formula:
[0171]
(i_s-n)/Y=floor(UE_ID/N)mod(ns/Y)
[0172]
Among them, n is a variable, representing the sequence number of the paging moment of the terminal device, which can be an integer in the range of [0, Y-1]; i_s is the index of the paging moment of the terminal device, corresponding to the sequence number n; ns is the above-mentioned number A parameter; Y is the above-mentioned maximum number, which can be the above-mentioned first ratio or the above-mentioned parameter Y; UE_ID is the identification of the above-mentioned terminal device; N is the total number of paging frames in the DRX cycle of the terminal device.
[0173]
In this embodiment, the index i_s of the current PO is also reused, but the formula for determining i_s is updated so that the paging moments belonging to the same terminal device are concentrated.
[0174]
In another embodiment, the terminal device can determine its own paging moment index according to the following formula:
[0175]
i_s=floor(UE_ID/N)mod(ns/Y);
[0176]
i_s+1+(n-1)*(ns/Y);
[0177]
Among them, i_s+1 is the index of the first paging moment of the terminal device, i_s+1+(n-1)*(ns/Y) is the index of the nth paging moment of the terminal device, and ns is the index of the first paging moment of the terminal device. A parameter, Y is the above-mentioned maximum number, which can be the above-mentioned first ratio, or the above-mentioned parameter Y, n<=Y, UE_ID is the identification of the terminal device, and N is the total number of paging frames in the DRX cycle of the terminal device .
[0178]
In this embodiment, the definition of i_s is modified, i_s+1 is used to represent the index of the first PO of the terminal device, and the formula for determining i_s is updated so that different paging moments belonging to the same terminal device are discrete. Therefore, the indexes of all paging moments of the terminal equipment are obtained: i_s+1, i_s+ns/Y+1, i_s+2*(ns/Y)+1,..., i_s+1+(n-1)*( ns/Y), n<=Y.
[0179]
In another embodiment, the terminal device can determine its own paging moment index according to the following formula:
[0180]

[0181]

The ratio can also be the aforementioned parameter Y, n<=Y, UE_ID is the identification of the terminal device, and N is the total number of paging frames in the DRX cycle of the terminal device.
[0183]
In this embodiment, the definition of i_s is also modified, i_s+1 is used to represent the index of the first paging moment of the terminal device, and the formula for determining i_s is updated so that different paging moments belonging to the same terminal device are concentrated of. Thus, the indexes of all paging moments of the terminal device are obtained: i_s+1, i_s+2,..., i_s+n, n<=Y.
[0184]
In this embodiment, the terminal device can monitor the paging at part of the paging moments that can be monitored, until a page is received or the network instructs to stop monitoring or monitor all the paging moments; or, the terminal device can also monitor the paging at all the paging moments. Monitor paging at all paging moments.
[0185]
For example, as mentioned above, Y represents the maximum number of paging moments that a terminal device can monitor, which means that a terminal device can monitor a maximum of Y paging moments in a DRX cycle. The terminal device can monitor paging at all its own paging moments, that is, the terminal device monitors Y paging moments; the terminal device can also monitor paging only at part of its own paging moments until it receives a page, or Monitor Y. That is to say, in a DRX cycle, the terminal device monitors paging, and when it receives paging or reaches Y, it stops monitoring. In other words, in multiple paging moments of a terminal device in a DRX cycle, the same paging information can be transmitted, or different content can be transmitted; if the paging content is the same, then the terminal device only monitors part or all of it. Otherwise, the terminal device monitors everything. In addition, the behavior of the terminal device can also be controlled by the network device. For example, the network device notifies the terminal device to stop monitoring at a paging moment or notifies the terminal device that there is no paging, then the terminal device can No more listening.
[0186]
The method of this embodiment increases the total paging moment by supporting more paging moments in one paging frame. Using the method of this embodiment, the number of terminal devices that are paged at the same paging moment is reduced. In this way, when a paging moment fails to send or monitor a paging message due to a channel detection failure, the number of affected terminal devices is reduced. To a certain extent, it alleviates the situation that the channel detection fails and the terminal device cannot be paged due to the failure to send or monitor the paging message.
[0187]
Example 3
[0188]
This embodiment provides a method for configuring and determining a paging opportunity. The method is applied to an unlicensed frequency band (NR-U) based on a new wireless and applied to a network device. Different from Embodiment 1 and Embodiment 2, the method of increasing the total paging moment by extending the paging moment in a paging frame, this embodiment increases the use of the paging moment (PO) by expanding the paging moment (PO) A paging opportunity to page a specific terminal.
[0189]
Fig. 9 is a schematic diagram of the method of configuring and determining a paging opportunity of this embodiment. As shown in Fig. 9, the method includes:
[0190]
Step 901: The network device generates fourth configuration information, where the fourth configuration information includes a second parameter associated with a paging moment, and a paging moment associated with the second parameter includes a first number of downlink control channel listening moments Or include a second number of sets of downlink control channel listening moments, where the first number is related to a synchronization signal block (SSB);
[0191]
Step 902: The network device sends the fourth configuration information.
[0192]
This embodiment does not limit the manner of generating the fourth configuration information.
[0193]
This method expands the paging moment to increase the paging opportunity for paging a specific terminal device, thereby overcoming the reduction of paging opportunity caused by channel detection failure and further possible network devices that cannot find terminal devices or cannot be timely. Adjust the system information update of terminal equipment and the transmission of PWS information.
[0194]
In an implementation of this embodiment, a paging moment associated with the second parameter includes a first number of downlink control channel (PDCCH) listening moments.
[0195]
In this embodiment, one paging moment includes more (first number) continuous PDCCH monitoring moments, as shown in FIG. 10.
[0196]
In this embodiment, the above-mentioned first number is related to SSB, which is defined as Synchronization Signal/Physical Broadcast Channel Block (SS/PBCH Block, Synchronization Signal/Physical Broadcast CHannel Block), referred to as Synchronization Signal Block (SSB) for short.
[0197]
For example, the first number may be at least one of the following, for example: the number of SSBs actually transmitted (S) determined according to the information provided in the first system information block (SIB1); according to the information provided in the first system information block (SIB1) The integer multiple (xS) of the actual transmitted SSB number determined by the information; the number determined by the number of SSBs determined by the information provided by the network (S'); and the integer multiple of the number determined by the number of SSBs determined by the information provided by the network ( xS').
[0198]
The information provided in the foregoing first system information block is, for example, ssb-PositionsInBurst. The aforementioned x may be an integer greater than 1. The information provided by the above-mentioned network is, for example, at least one of the number of actually transmitted SSBs, the offset between candidate time domain SSB positions, and the offset between candidate SSB groups, and the network device can use, for example, downlink control information (DCI) To provide the above-mentioned information, in addition, S'may be the same as or different from the above-mentioned S.
[0199]
The method of this embodiment extends the paging moment in a way that one paging moment includes more continuous PDCCH listening moments; among them, the time for the terminal device to monitor the paging opportunity is concentrated, and the advantage is that the terminal wireless transceiver device is switched on and off. The number of times and the duration of opening remain basically unchanged, so that the terminal energy consumption is not much increased compared to working on the licensed frequency band.
[0200]
In another implementation manner of this embodiment, a paging moment associated with the second parameter includes a second number of downlink control channel listening moments.
[0201]
In this embodiment, one paging moment includes multiple groups (the second number of groups) of continuous PDCCH monitoring moments. In this embodiment, the multiple groups of continuous PDCCH monitoring moments can be continuously mapped to one paging moment, as shown in FIG. 11 As shown, the two sets of PDCCH monitoring moments of PO1 are continuously mapped; or, the above-mentioned multiple sets of continuous PDCCH monitoring moments can also be sequentially mapped to different paging moments. As shown in Figure 12, the two consecutive sets of PDCCH monitoring moments are sequentially mapped to PO1 and PO2.
[0202]
In this embodiment, the above-mentioned second parameter may include at least one of the following information: the value of a second number of initial PDCCH listening moments at a paging moment; and a second number of initial PDCCH listening moments at a paging moment In the time domain, each group of PDCCH monitoring moments are collectively associated (or belong to or mapped) to different paging moments, or each group of PDCCH monitoring moments are sequentially and dispersedly associated (or belong to or mapped) to different paging moments. Call the moment.
[0203]
As shown in Figure 11 and Figure 12, multiple groups of continuous PDCCH monitoring moments are continuously mapped to a PO, which can be a PO corresponding to multiple initial PDCCH values, or an initial PDCCH of a PO includes multiple values, which can be modified by modifying the current parameters It can also be achieved by introducing new parameters, or by modifying current parameters and introducing new parameters.
[0204]
For example, in a method in which an initial PDCCH of a PO includes multiple values, it is assumed that a PO uses two values, and the first two values ​​correspond to the first PO (that is, PO1, including the first group of PO1 and the first group of PO1). Two groups), and the next two values ​​correspond to the second PO (that is, PO2), so that each PO can include multiple consecutive sets of PDCCH monitoring moments.
[0205]
In this example, the foregoing second parameter is, for example, firstPDCCH-MonitoringOccasionOfPO. By modifying this parameter, it is realized that an initial PDCCH of a PO includes multiple values. For example, modify the value of Z in the current field description of the above parameter, where Z is the maximum number of groups of continuous PDCCH listening moments that a PO can include. Z can be predefined or configured by the network; it can be cell-specific or terminal-specific; in different RRC states, it can be the same or different. Figure 13 is an example of the structure of the parameter firstPDCCH-MonitoringOccasionOfPO, in which the content enclosed by the dashed frame is the above-mentioned Z.
[0206]
For another example, in the method of using one PO corresponding to multiple initial PDCCH values, existing parameters can be used and new parameters can be introduced. For example, currently, a PO corresponds to an initial PDCCH value, which is described by the parameter firstPDCCH-MonitoringOccasionOfPO. On this basis, this embodiment adds another parameter firstPDCCH1-MonitoringOccasionOfPO, and the configuration method of the parameter firstPDCCH1-MonitoringOccasionOfP and the above-mentioned parameter firstPDCCH-MonitoringOccasionOfPO It can be the same as the description method. Therefore, through these two parameters, it is realized that one PO corresponds to two initial PDCCH values. FIG. 14 is an example of the structure of the parameter firstPDCCH-MonitoringOccasionOfPO, and FIG. 15 is an example of the structure of the parameter firstPDCCH1-MonitoringOccasionOfPO, and the description of the above-mentioned parameters is shown by a dashed frame.
[0207]
In this example, the above second parameters are firstPDCCH-MonitoringOccasionOfPO and firstPDCCH1-MonitoringOccasionOfP. The names of the above parameters can be changed, and the number is not limited to 2.
[0208]
For another example, in the method where one PO corresponds to multiple initial PDCCH values, the parameter structure can also be modified, for example, the structure of the currently used parameter firstPDCCH-MonitoringOccasionOfPO can be modified. FIG. 16 is an example of the structure of the modified parameter firstPDCCH-MonitoringOccasionOfPO. The description of the above parameters is shown by a dashed frame, where Z is the maximum number of groups of continuous PDCCH monitoring moments that a PO can include. Z can be predefined or configured by the network; it can be cell-specific or terminal-specific; in different RRC states, it can be the same or different.
[0209]
In this embodiment, a new parameter can also be introduced to define the interval between the two sets of PDCCH monitoring moments corresponding to each PO. This parameter can be in units of PDCCH or symbols; in addition, the PDCCH corresponding to each PO can also be determined. The number of groups at the listening moment (the second number group). The number can be defined in the standard or can be configured by the network. In this way, multiple groups of continuous PDCCH monitoring moments can also be continuously mapped to one PO.
[0210]
For example, in this example, the network device may also send fifth configuration information to the terminal device. The fifth configuration information includes the PDCCH listening moments of the second group included in a paging moment associated with the second parameter. Therefore, the above-mentioned interval is defined by introducing new parameters. In addition, the network device may also send sixth configuration information to the terminal device, where the sixth configuration information configures the above-mentioned second quantity, thereby defining the above-mentioned second quantity by introducing a new parameter.
[0211]
As shown in Figure 12, multiple groups of continuous PDCCH listening moments are sequentially mapped to different POs, which can be that one PO corresponds to multiple initial PDCCH values, or one initial PDCCH of one PO includes multiple values, which can be achieved by modifying the current parameters. It can also be achieved by introducing new parameters, or by modifying current parameters and introducing new parameters.
[0212]
For example, in the method of using an initial PDCCH to include multiple values, assuming that a PO uses 2 values ​​and there are 2 POs, then the first and third values ​​correspond to the first PO (that is, PO1), and the The second and fourth values ​​correspond to the second PO (that is, PO2).
[0213]
The method of modifying the parameter or the method of introducing a new parameter or the method of modifying the parameter and introducing a new parameter is the same as that of FIG. 11, and the description is omitted here.
[0214]
The method of this embodiment extends the paging moment by a way that one paging moment includes multiple sets of continuous PDCCH listening moments. For example, the paging moments belonging to the same terminal are gathered together from a time perspective in a continuous mapping manner. The advantage is that the number of times the terminal’s wireless transceiver device is turned on and off and the duration of opening are basically the same, so that the terminal’s energy consumption is not much increased compared to working on the authorized frequency band; another example is that it belongs to the same terminal by mapping according to the sequence of different paging moments. The paging moments are discrete from a time perspective. The advantage is that the probability of LBT failure at these paging moments is reduced, thereby increasing the possibility of finding these terminals or notifying these terminals in time for system information updates and PWS information transmission.
[0215]
In another implementation of this embodiment, the paging moment is extended by extending the duration of the PDCCH monitoring moment. For example, the duration of the PDCCH monitoring moment can be extended to 4 symbols or even greater than 4 symbols.
[0216]
In this embodiment, only the PDCCH monitoring moment used for paging can be extended. For example, the duration of at least one PDCCH monitoring moment included in one paging moment associated with the second parameter is greater than or equal to 4 symbols. . Fig. 17 shows a situation where the PDCCH listening time for paging is extended.
[0217]
In this embodiment, the duration of all PDCCHs can also be extended. For example, the duration of all PDCCHs is greater than or equal to 4 symbols, thereby also extending the PDCCH monitoring time for paging.
[0218]
This embodiment extends the paging moment by extending the duration of the PDCCH monitoring moment; in this method, the time for the terminal to monitor the paging opportunity is concentrated. The advantage is that the number of times the terminal’s wireless transceiver device is switched on and the duration of opening are basically No change, so the terminal energy consumption will not increase much compared to working on the licensed frequency band.
[0219]
In this embodiment, the above-mentioned various embodiments can be used in combination or separately, which is not limited in this embodiment.
[0220]
In this embodiment, in order to assist the terminal device in determining its own paging moment index, the network device may also send third configuration information to the terminal device. The third configuration information may include the maximum paging moment that the terminal device can monitor. The number (Y), therefore, the terminal device can determine its own paging moment index according to the maximum number (Y) in combination with other parameters or configurations.
[0221]
For example, the terminal device may determine the first PDCCH monitoring time number of the i_s+1th PO based on the i_s+1 value of the above parameter firstPDCCH-MonitoringOccasionOfPO, for example, the number of the first PDCCH monitoring time mod p=firstPDCCH-MonitoringOccasionOfPO's i_s+ 1 value, where p=ns/Y, which will be specifically described in the following embodiments.
[0222]
The content of the above third configuration information is the same as that of Embodiment 1, and the description is omitted here, and, as described in Embodiment 1, the third configuration information is optional, that is, the terminal device can also be based on the above The second parameter and other configurations determine the index of the own paging moment.
[0223]
The method of this embodiment reuses the current paging mechanism to the greatest extent, including the configuration of paging frames and paging moment related parameters, the calculation of paging frames and paging moments, etc., thereby reducing research and testing costs and equipment costs.
[0224]
Example 4
[0225]
This embodiment provides a method for configuring and determining a paging opportunity. The method is applied to a new radio-based unlicensed frequency band (NR-U) and applied to a terminal device, which corresponds to the terminal device side of the method in Embodiment 3. The description of the same content as in embodiment 3 will not be repeated.
[0226]

[0232]
For example, the terminal device can determine the above position according to the following relationship:
[0233]
The number of initial downlink control channel monitoring moments mod p=i_s+1 value of firstPDCCH-MonitoringOccasionOfPO;
[0234]
Among them, p=ns/Y, i_s+1 is the position of the start downlink control channel monitoring moment of the first paging moment of the terminal device, ns and firstPDCCH-MonitoringOccasionOfPO are the foregoing second parameters, and Y is the foregoing maximum number.

[0236]
In this embodiment, similar to Embodiment 3, the second parameter may include at least one of the following information: the value of the second number of initial downlink control channel listening moments at a paging moment; and an initial downlink at a paging moment The value of the second number of control channel listening moments; among them, in the time domain, each group of downlink control channel listening moments are collectively associated with different paging moments, or each group of downlink control channel listening moments are sequentially and dispersedly associated with different paging moments. Call the moment.
[0237]
In this embodiment, similar to Embodiment 3, the duration of at least one downlink control channel listening moment included in the at least one paging moment associated with the second parameter may be greater than or equal to 4 symbols.
[0238]
In this embodiment, similar to Embodiment 2, the terminal device can monitor paging on part of the paging opportunities that can be monitored, until a page is received or the network instructs to stop monitoring or monitor all paging opportunities; or the terminal device can also Monitor paging on all paging opportunities that can be monitored.
[0239]
For example, one paging moment may include multiple sets of continuous PDCCH listening moments. The terminal device can monitor paging at all PDCCH monitoring moments of its own paging moment, and the terminal device can also monitor paging only on part of the PDCCH monitoring moments of its own paging moment, until it receives a page, or monitors everything. PDCCH monitoring moment. That is to say, in a DRX cycle, the terminal device monitors the paging, and stops monitoring when it receives the paging or monitors all PDCCH monitoring moments. In other words, in multiple sets of continuous PDCCH monitoring moments in a paging moment, the same paging information can be transmitted, or different content can be transmitted; if the paging content is the same, then the terminal device only monitors part or all of it, Otherwise, the terminal device monitors everything. In addition, the behavior of the terminal device can also be controlled by the network device. For example, the network device notifies the terminal device to stop monitoring during a set of continuous PDCCH monitoring moments or notifies the terminal device that there is no paging, then in the remaining PDCCH monitoring moments of the paging moment, The terminal device can no longer monitor.
[0240]
The method of this embodiment reuses the current paging mechanism to the greatest extent, including the configuration of paging frames and paging moment related parameters, the calculation of paging frames and paging moments, etc., thereby reducing research and testing costs and equipment costs.
[0241]
Example 5
[0242]
This embodiment provides a method for configuring and determining a paging opportunity, and the method is applied to a network device. It is different from the method of increasing the total paging moment by extending the paging moment in a paging frame in Embodiment 1 and Embodiment 2, and it is different from the method in Embodiment 3 and Embodiment 4 by extending the paging moment in the paging frame. The method of expanding the PDCCH monitoring moment to increase the paging opportunity for paging a specific terminal is also different. In this embodiment, a short DRX cycle is applied to increase the paging opportunity for paging a specific terminal.
[0243]
FIG. 19 is a schematic diagram of the method of configuring and determining a paging opportunity of this embodiment. As shown in FIG. 19, the method includes:
[0244]
Step 1901: The network device generates seventh configuration information, where the seventh configuration information includes a third parameter associated with a DRX cycle, and the third parameter is associated with one or more DRX cycles, and the DRX cycle is used for terminal device access NR-based unlicensed frequency bands or NR-based unlicensed frequency bands provide services;
[0245]
Step 1902: The network device sends the seventh configuration information to the terminal device.
[0246]
This embodiment does not limit the manner of generating the seventh configuration information.
[0247]
In this embodiment, the aforementioned third parameter is the same as or different from the parameter associated with the DRX cycle of the NR-based licensed frequency band, and the value of the aforementioned third parameter is smaller than the value of the parameter associated with the DRX cycle of the NR-based licensed frequency band .
[0248]
Therefore, since the value of the third parameter is smaller than the value of the parameter associated with the DRX cycle of the NR-based licensed frequency band, that is, compared to the NR-based licensed frequency band, the DRX cycle becomes shorter. For terminal equipment, one DRX cycle There is a paging moment, when the DRX cycle becomes shorter, the paging paging moment within the same time increases, thereby increasing the paging opportunity for paging a specific terminal.
[0249]
In an implementation of this embodiment, the above-mentioned third parameter is associated with a DRX cycle, and this parameter can be applied when the terminal device resides on the NR-U or is served by the NR-U. In this embodiment, the above-mentioned parameter may be at least one of the following: a terminal-specific DRX cycle configured by RRC; a terminal-specific DRX cycle configured by a higher layer; and a default DRX cycle broadcast in the system information.
[0250]
In another implementation of this embodiment, the above-mentioned third parameter is associated with at least two DRX cycles, and the time domain lengths of the at least two DRX cycles are different. In this embodiment, the third parameter is associated with two DRX cycles with different time domain lengths as an example, that is, one long DRX cycle and one short DRX cycle. For the case where more than two DRX cycles are associated with the third parameter, the two The situation of two DRX cycles is the same, and the description will not be repeated for the situation of more than two.
[0251]
In this embodiment, which DRX cycle to use may depend on the implementation of the terminal, or may be indicated by the network, or may be defined in a regular manner.
[0252]
For example, the network device may send first indication information to the terminal device, where the first indication information indicates one of the above two DRX cycles, and the terminal device uses the DRX cycle indicated by the first indication information to access the NR-based unlicensed frequency band or Services are provided by NR-based unlicensed frequency bands. The foregoing first indication information may be carried by DRX, system information, etc., which is not limited in this embodiment.
[0253]
For another example, the network device may send second indication information to the terminal device, and the second indication information configures or activates the rule for switching between the above two DRX cycles and/or determines the parameters for switching between the two DRX cycles.
[0254]
The aforementioned rule may be at least one of a timer-based rule, a counter-based rule, and a threshold-based rule.
[0255]
The above-mentioned timer-based rule refers to switching to another DRX cycle when the timer associated with one DRX cycle expires.
[0256]
In the timer-based rule, a long to short DRX conversion timer can be maintained. When the long DRX is being applied or the terminal enters the idle or inactive state, the timer is started; once the timer expires, the short DRX is applied immediately or after the current DRX cycle (or the timer value is a multiple of the long DRX cycle) ; If long DRX is currently applied, the timer (re)starts when receiving downlink transmissions on NR-U, such as paging, DRS, and system information; if short DRX is currently applied, when receiving the downlink transmission on NR-U For downlink transmission, such as paging, DRS, and system information, short DRX is applied immediately or after the current DRX cycle.
[0257]
In the timer-based rule, two timers can also be maintained, namely a long-to-short DRX conversion timer and a short-to-long DRX conversion timer. When long DRX is being applied or when the terminal enters idle or inactive state, start the long to short DRX conversion timer and once the timer expires, apply the short DRX; when applying short DRX, start the short to long DRX conversion timer And once the timer expires, long DRX is applied.
[0258]
The above-mentioned counter-based rule refers to switching to another DRX cycle when the number of times of using one DRX cycle reaches the maximum value.
[0259]
In the counter-based rule, the maximum value of consecutive long DRX cycles can be used. Once the number of consecutive long DRX cycles reaches the maximum, short DRX is applied; when downlink transmissions on NR-U, such as paging, DRS, and system information are received, short DRX is applied immediately or after the current DRX cycle.
[0260]
In the counter-based rule, the maximum value of the continuous long DRX cycle and the maximum value of the continuous short DRX cycle (the same or different values) can also be used. Once the number of consecutive long or short DRX cycles reaches the maximum, short or long DRX is applied.
[0261]
In the above threshold-based rule, when the channel measurement result of one DRX cycle exceeds or is less than the threshold, switch to another DRX cycle.
[0262]
In the threshold-based rule, the terminal device can perform measurement. When the measurement result reaches the threshold, or the measurement time reaches T (T can be 0), the DRX conversion is performed; the measurement can be load-related (such as resource usage, Channel occupancy) or interference-related (such as SINR, RSSI) can also be measured in the aforementioned timer-based rule or counter-based rule; further, hysteresis parameters can be used.
[0263]
For example: Use long to short DRX conversion threshold. The terminal performs measurement; when the long-to-short DRX conversion threshold is reached, short DRX is applied; when downlink transmission on NR-U, such as paging, DRS, and system information, is received, short DRX is applied immediately or after the current DRX cycle.
[0264]
For another example, the long-to-short DRX conversion threshold and the short-to-long DRX conversion threshold are used. Once the long-to-short DRX conversion threshold is reached, short DRX is applied; once the short-to-long DRX conversion threshold is reached, long DRX is applied.
[0265]
In this embodiment, the aforementioned parameters for determining the switch between two DRX cycles may include at least one of the following: the value of each timer associated with the timer rule; the maximum value of the DRX cycle associated with the counter rule; and the threshold rule The associated threshold. After the parameter is configured or activated by the second indication information, the terminal device can switch between the above two DRX cycles based on the foregoing rule in combination with the parameter.
[0266]
In this embodiment, the value of the above one or more DRX cycles may be defined in the standard.
[0267]
In this embodiment, if a short DRX cycle is applied, the terminal device can monitor a paging moment in each DRX cycle, or monitor the PDCCH scrambled by SI-RNTI during the paging moment, or during the paging moment Or monitoring the PDCCH scrambled by SI-RNTI outside the paging moment, this embodiment does not specifically limit the behavior of the terminal device.
[0268]
The method of this embodiment increases the paging opportunity for paging a specific terminal by applying a short DRX cycle. In the implementation of applying only one DRX cycle, the current paging mechanism is reused to the greatest extent, including the configuration of paging frames and paging moment related parameters, the calculation of paging frames and paging moments, etc., thereby reducing research and testing costs, Reduce equipment costs. In the implementation of applying the long DRX cycle and the short DRX cycle, it is possible to switch between the two DRX cycles, which increases the paging opportunity and reduces the energy consumption of the terminal.
