Measurement method and device based on SSB
Technical field
[0001]
The present invention relates to the field of communications, in particular to a measurement method and device based on SSB.
Background technique
[0002]
3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) is studying related topics of next-generation wireless communication systems. In the next-generation wireless communication system, for example, in the New Radio (NR, New Radio) system, a synchronization signal block (Sychronization Signal Block, SSB) in a cycle is transmitted in a half sub-frame (half sub-frame), The length of one half subframe is 5ms. In the NR system, for different frequency bands and subcarrier spacing, the time domain position of the SSB in a half-subframe is predefined, and the SSB at different time domain positions is represented by the SSB index (SSB index), and the demodulation in one SSB The reference signal (Demodulation Reference Sgnal, DMRS) and the physical broadcast channel (Physical Broadcast Channel, PBCH) may indicate the SSB index corresponding to the SSB. For example, for the frequency band of 3-6 GHz, one half subframe includes the time domain positions of the predefined 8 SSBs, and these 8 SSBs correspond to the SSB index with a value of 0-7 in a one-to-one correspondence.
[0003]
In the NR system, the network can configure a connected user equipment (User Equipment, UE) to perform measurements and report the measurement results according to the measurement configuration. The measurement configuration is sent to the UE through RRC signaling, for example, through an RRCReconfiguration message. The measurement configuration includes, for example, at least one of the following parameters: measurement objects (MOs, Measurement objects), reporting configurations (Reporting configurations), measurement identities, quantization configurations (Quantity configurations), and measurement gaps (Measurement gaps). The object includes the list of measurement objects that the UE should measure. A measurement object corresponds to the time-frequency domain position and subcarrier spacing (SCS) of a specific reference signal. The report configuration includes the measurement information that the UE should report. The measurement identifier represents the measurement object and The corresponding relationship of the reported configuration, a measurement identifier represents the corresponding relationship between a measurement object and a reported configuration.
[0004]
Specifically, the network may configure the UE to perform measurement based on SSB and/or CSI-RS (CSI reference signals). Taking SSB-based measurement information as an example, the measurement object indicates the time-frequency domain position and SCS of the SSB to be measured.
[0005]
When the UE performs measurement according to the MO, the UE may measure multiple cells corresponding to the MO, and the multiple cells send the SSB at the time-frequency domain position indicated by the MO and the SCS indicated by the MO. The UE can distinguish the SSBs corresponding to different cells by the physical cell ID (PCI) corresponding to the SSBs, that is, consider that the SSBs corresponding to the same PCI belong to the same cell. The multiple cells may include different types of cells, for example, a serving cell, a cell listed in the MO, and a cell not listed in the MO but detected by the UE.
[0006]
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. 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.
[0007]
Summary of the invention
[0008]
In NR Rel-15, the SSB in the SSB transmission window corresponds to the beam one-to-one, or in other words, the SSB time domain position (characterized by the SSB index) in the SSB transmission window corresponds to the beam one-to-one. Moreover, since it is only for the licensed frequency band, generally, the SSB time domain positions corresponding to the SSB sets actually sent in different SSB sending windows are the same. Therefore, the UE can obtain the measurement result of the beam corresponding to the SSB time domain position according to the one-to-one correspondence between the SSB time domain position and the beam, or obtain the measurement result of the corresponding cell based on the measurement of one or more beams, thereby converting The measurement results are reported to the network.
[0009]
However, the inventor found that in NR-U, considering that the transmission of SSB is limited to LBT (Listen Before Talk), in order to ensure cell coverage, an SSB transmission window for sending SSB is added. Time domain position of the candidate SSB. The increase in the number of candidate SSB time-domain positions may increase the complexity and power consumption of UE measurement.
[0010]
On the other hand, because the network device can only send SSB when it detects that the channel is idle, in one SSB sending window, the network device may only send a part of the SSB, or even not send the SSB. The SSB set sent in different SSB sending windows corresponds to The SSB time domain location may be different. Therefore, if the existing method is used for measurement, it may be difficult to ensure the accuracy of the measurement result, which in turn affects the reliability of mobility management.

[0055]
Various implementations of the 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.
[0056]
Example 1
[0057]
The embodiment of the present invention provides an SSB-based measurement method, which is applied to the user equipment side.
[0058]
Fig. 2 is a schematic diagram of an SSB-based measurement method according to Embodiment 1 of the present invention. As shown in Fig. 2, the method includes:
[0059]
Step 201: According to at least one of the quasi co-location (QCL) relationship between the SSBs corresponding to the first cell, the SSB transmission restriction corresponding to the first cell, and the detection result of the SSB of the first cell, Obtain the first measurement result of the first cell;
[0060]
Step 202: Generate measurement information of the first cell according to the first measurement result of the first cell; and
[0061]
Step 203: Send the measurement information to the network.
[0062]
In this way, the first measurement result of the first cell is obtained according to at least one of the QCL relationship between the SSBs corresponding to the first cell, the SSB transmission restriction corresponding to the first cell, and the detection result of the SSB of the first cell, and According to the first measurement result, the measurement information of the first cell is generated and reported, which can effectively improve the accuracy of the SSB-based measurement report and reduce the complexity and power consumption of the SSB-based measurement.
[0063]
In this embodiment, the first cell may be a serving cell or a non-serving cell of the UE. For example, the non-serving cell may be a cell listed in the MO or a cell not listed in the MO but detected by the UE.
[0064]
In this embodiment, the QCL relationship between SSBs may also be referred to as the association relationship between SSBs and beams. When the two SSBs are QCL, it can also be said that the beams associated with the two SSBs are the same. For the convenience of further explanation, the latter method is used below. In this embodiment, one window includes multiple candidate SSB time domain positions (for example, called candidate SSB (time) position), and the UE may try to receive the SSB at each candidate SSB time domain position for measurement. For UE measurement, this window may be called a transmission window or a measurement window, for example, it may be represented as a DRS transmission window, an SMTC window, a DMTC window, and so on. Considering a multi-beam (multi-beam) scenario, a cell may have only one or multiple beams. Since the transmission of SSB is limited to LBT, a beam may require transmission opportunities in one window to ensure coverage. That is, there may be SSBs at different candidate SSB time domain positions associated with the same beam in one window.
[0065]
In an embodiment, the association relationship between the SSB and the beam in a window may be determined according to the corresponding relationship between the candidate SSB time domain position and the beam. And the correlation between the SSB and the beam in different windows is the same.
[0066]
For example, Table 1 shows the correspondence between candidate SSB time domain positions and beams in a window.

Table 1
[0069]
As shown in Table 1, a window includes 8 candidate SSB time domain positions, and the candidate SSB time domain position index (for example, candidate SSB(time) position index) is 0 to 7, and 4 beams are used. , The beam index (for example, beam index, SSB index) is 0 to 3 respectively, where the SSB sent at the candidate SSB time domain position index of 0 and 4 corresponds to the same beam 0, and the candidate SSB time domain position index is 1 The SSB sent with 5 corresponds to the same beam 1, the SSB sent at the candidate SSB time domain position index 2 and 6 corresponds to the same beam 2, and the SSB sent at the candidate SSB time domain index 3 and 7 corresponds to the same Beam 3. Table 1 is only an example. The number of SSBs in a window may also be 10 (SSB SCS=15kHz) or 20 (SSB SCS=30kHz), and the number of beams may be, for example, an integer of 1-8.
[0070]
In another embodiment, the association relationship between the SSB and the beam in one window or different windows may be determined according to the DMRS sequence in the SSB. At this time, if a candidate SSB time domain position corresponds to a DMRS sequence, it can also be determined according to the candidate SSB time domain position; otherwise, it may only be determined according to the sequence.
[0071]
In this embodiment, since the time-domain positions and the number of beams of candidate SSBs in a window of different cells may be different, the association relationship between SSBs and beams corresponding to different cells may also be different.
[0072]
In this embodiment, the SSB transmission restriction includes, for example, at least one of the following: the specified number of SSB transmissions in a window, the maximum number of SSB transmissions in a window, the SSB transmission range in a window, and the corresponding beam in a window. The SSB specifies the number of transmissions and the maximum number of SSB transmissions corresponding to one beam in a window.
[0073]
In this embodiment, since the candidate SSB time domain positions, the number of beams, and the number of SSBs to be transmitted in a window of different cells may be different, the SSB transmission restrictions corresponding to different cells may also be different.
[0074]
In this embodiment, the detection result of the SSB of the first cell refers to the UE's detection result of the SSB sent by the first cell. For example, in one window or multiple windows, the SSB received power corresponding to the time domain position of the candidate SSB The size, the number of SSBs detected by the UE, and the time domain position of the candidate SSB where the detected SSB is located.
[0075]
In step 201, according to the quasi co-location (QCL) relationship between the SSBs corresponding to the first cell, the SSB transmission restriction corresponding to the first cell, and the detection result of the SSB of the first cell At least one, the first measurement result of the first cell is obtained.
[0076]
FIG. 3 is a schematic diagram of a method for implementing step 201 in Embodiment 1 of the present invention. As shown in Figure 3, step 201 includes:
[0077]
Step 301: Obtain a second measurement result of the first cell according to at least one of the QCL relationship between the SSBs corresponding to the first cell, the SSB transmission restriction corresponding to the first cell, and the detection result of the SSB of the first cell. 2. The measurement result is the beam level or the SSB time domain position level; and
[0078]
Step 302: Obtain a first measurement result according to at least one second measurement result.
[0079]
In this embodiment, the first measurement result may be the measurement result of the L3 layer (layer 3), that is, the measurement value of L3 filtering.
[0080]
In this embodiment, the second measurement result may be the measurement result of the L1 layer (layer 1), that is, the measurement value of L1 filtering.
[0081]
The first measurement result is RSRP, RSRQ or SINR, and correspondingly, the second measurement result is SS-RSRP, SS-RSRQ or SS-SINR. That is, if the first measurement result is RSRP, the first measurement result should be obtained according to SS-RSRP.
[0082]
In this embodiment, the second measurement result is SS-RSRP as an example to illustrate how the UE obtains the second measurement result.
[0083]
In step 301, the second measurement of the first cell can be obtained according to at least one of the QCL relationship between the SSBs corresponding to the first cell, the SSB transmission restriction corresponding to the first cell, and the detection result of the SSB of the first cell. result. The second measurement result is beam level (beam level, or beam-specific) or time domain position level (position level, or position-specific). That is, one second measurement result corresponds to one beam or one SSB time domain position (or candidate SSB time domain position).
[0084]
For the case where the second measurement result is the beam level, Table 2 shows the correspondence between candidate SSB time domain positions, beams, and SS-RSRP in one window.

As shown in Table 2, the SS-RSRP as the second measurement result corresponds to beams, that is, one SS-RSRP corresponds to one beam, and different beams correspond to different SS-RSRP. Table 2 is only an example. The number of SSBs in a window may also be 10 (SSB SCS=15kHz) or 20 (SSB SCS=30kHz), and the number of beams may be, for example, an integer from 1 to 8.
[0088]
For the case where the second measurement result corresponds to the time domain position, Table 3 shows the correspondence between the time domain position of the SSB in one window and the SS-RSRP.

[0091]
As shown in Table 3, the SS-RSRP as the second measurement result corresponds to the time domain position, that is, one time domain position corresponds to one SS-RSRP, and different time domain positions correspond to different SS-RSRP. Table 3 is only an example. The number of SSBs in a window may also be 10 (SSB SCS=15kHz) or 20 (SSB SCS=30kHz), and the number of beams may be, for example, an integer of 1-8.
[0092]
Hereinafter, how to obtain the second measurement result in step 301 is exemplarily explained.
[0093]
Case 1) The case where the second measurement result is the beam level will be described.
[0094]
FIG. 4 is a schematic diagram of a method for implementing step 301 in Embodiment 1 of the present invention. As shown in Figure 4, step 301 includes:
[0095]
Step 401: Select an SSB from a plurality of SSBs corresponding to the first beam at different candidate SSB time domain positions in one window; and
[0096]
Step 402: Obtain a second measurement result corresponding to the first beam according to the selected SSB.
[0097]
In step 401, SSBs are selected according to each window, and the number and/or time domain positions of the SSBs selected in different windows may be the same or different.
[0098]
For the case where there is a successfully transmitted SSB in a window, when there is at least one SSB corresponding to the first beam, at least one SSB is selected from the SSB. In addition, there may also be a case where there is no SSB successfully transmitted in the window. , At this time, the SSB is not selected, that is, 0 SSB is selected, or there may be a situation where there are successfully transmitted SSBs in a window but there is no SSB corresponding to the first beam. At this time, the selected one corresponds to the first beam. The number of SSB is also zero.
[0099]
Example 1.1) Obtain the second measurement result of the first cell according to the QCL relationship between the SSBs corresponding to the first cell. For example, according to the QCL relationship between the SSBs corresponding to the first cell, determine whether the SSB at a certain time domain position is used to obtain the second measurement result, that is, according to the QCL relationship between the SSBs corresponding to the first cell, select one A part of the SSB in the window obtains the second measurement result.
[0100]
For example, if the time domain position indexes of the multiple SSBs corresponding to the first beam are 0 and 4, respectively, the SSB with the time domain position index of 4 may be selected, and the SS-RSRP corresponding to the first beam is obtained according to the SSB.
[0101]
Example 1.2) Obtain the second measurement result of the first cell according to the SSB transmission restriction corresponding to the first cell. For example, according to the SSB transmission restriction corresponding to the first cell, determine whether the SSB at a certain time domain position is used to obtain the second measurement result, that is, according to the SSB transmission restriction of the first cell, select a part of the SSB in a window SSB gets the second measurement result.
[0102]
As described above, for example, the SSB transmission restriction corresponding to the first cell may include at least one of the following: the specified number of SSB transmissions in one window, the maximum number of SSB transmissions in one window, and the SSB transmission range in one window.
[0103]
For example, if the specified number of SSBs or the maximum number of SSBs in a window is set to X, and the UE receives an SSB at position x, it will not be based on positions other than x-X+1~x+X-1 in the window The SSB gets SS-RSRP.
[0104]
For example, the SSB sending range in a window is set to N, that is, if the SSB starts to be sent at position n in a window, the SSB cannot be sent at a position after n+N in the window. When the UE receives an SSB at position x, it does not obtain the SS-RSRP based on the SSB at positions other than x-N+1 to x+N-1 in the window.
[0105]
Example 1.3) Obtain the second measurement result of the first cell according to the QCL relationship between the SSBs corresponding to the first cell and the SSB transmission restriction corresponding to the first cell. For example, according to the QCL relationship between SSBs and the SSB transmission restriction, it is determined whether the second measurement result is obtained based on the SSB at a certain time domain position, that is, according to the QCL relationship between the SSBs and the SSB transmission restriction, a window corresponding to the same beam is selected A part of the SSB in the SSB obtains the corresponding second measurement result.
[0106]
As described above, the SSB transmission restriction corresponding to the first cell may also include at least one of the following: the specified number of SSBs corresponding to one beam in one window, and the maximum number of SSBs corresponding to one beam in one window. number.
[0107]
For example, the prescribed number of SSBs corresponding to one beam in one window or the maximum number of SSBs corresponding to one beam in one window is set to Y. For example, when the UE receives Y SSBs corresponding to the beams in a window, the corresponding SS-RSRP is not obtained based on the SSBs of the corresponding beams in other positions in the window.
[0108]
Example 1.4) In addition, based on Examples 1.1 to 1.3, the second measurement result of the first cell can be obtained by further combining the detection result of the SSB of the first cell.
[0109]
For example, according to the SSB transmission restriction of the first cell and the detection result of the SSB of the first cell, it is determined whether the SSB of a certain time domain position is used to obtain the second measurement result, that is, according to the SSB transmission restriction of the first cell and For the detection result of the SSB of the first cell, a part of the SSBs in a window is selected to obtain the second measurement result.
[0110]
Case 2) The case where the second measurement result corresponds to the position in the time domain will be described.
[0111]
FIG. 5 is another schematic diagram of the method for implementing step 301 in Embodiment 1 of the present invention. As shown in Figure 5, step 301 includes:
[0112]
Step 501: Select an SSB from multiple SSBs corresponding to the time domain position of the first SSB in different windows; and
[0113]
Step 502: Obtain a second measurement result corresponding to the time domain position of the first SSB according to the selected SSB.
[0114]
In this embodiment, for the case where the SSB corresponding to the time domain position of the first SSB is successfully transmitted in at least one window, at least one SSB is selected from the SSB corresponding to the time domain position of the first SSB successfully transmitted in the at least one window, For the case where the SSB corresponding to the time domain position of the first SSB is not successfully sent in a window, the number of SSBs corresponding to the time domain position of the first SSB selected is 0.
[0115]
Example 2.1) Obtain the second measurement result of the first cell according to the SSB transmission restriction of the first cell.
[0116]
The specific method of Example 2.1 is similar to that of Example 1.2. The difference is that the second measurement result in Example 2.2 is the SSB time domain position level. Similar content will not be repeated.
[0117]
Example 2.2) Obtain the second measurement result of the first cell according to the QCL relationship between the SSBs corresponding to the first cell and the SSB transmission restriction corresponding to the first cell.
[0118]
The specific method of Example 2.2 is similar to that of Example 1.3, except that the second measurement result in Example 2.2 is the SSB time domain position level. Similar content will not be repeated.
[0119]
Example 2.3) In addition, based on Examples 2.1 to 2.2, the second measurement result of the first cell can be obtained by further combining the detection result of the SSB of the first cell.
[0120]
The specific method of Example 2.3 is similar to that of Example 1.4, the difference is that the second measurement result in Example 2.3 is the SSB time domain position level. Similar content will not be repeated.
[0121]
Above, the implementation method of step 301 has been exemplified.
[0122]
In step 302, a first measurement result is obtained according to at least one second measurement result.
[0123]
In this embodiment, the first measurement result is obtained based on at least one second measurement result. The first measurement result may be cell-level (cell quantity/cell measurement quantity) or beam-level (beam quantity/beam measurement quantity) or position-level (position quantity/position measurement quantity) in time domain. , The second measurement result is the beam level or the position level of the time domain position.
[0124]
For example, the UE may obtain the first measurement result after L3 filtering according to the following formula (1):
[0125]
F n＝(1–a)*F n-1 +a*M n (1)
[0126]
Among them, M n is a value corresponding to at least one recent second measurement result, F n-1 is the first measurement result before the update, F n is the first measurement result after the update, a=1/2 (k/ 4) , k is the filter coefficient filterCoefficient.
[0127]
In this embodiment, the first measurement result used to generate the measurement information is obtained based on multiple M n , and the multiple M n are obtained based on the second measurement results obtained in different time periods. A time period generally includes multiple windows, that is, a second measurement result may be obtained by measuring SSB in multiple windows. Therefore, a first measurement result may be obtained based on the SSB of multiple windows.
[0128]
Hereinafter, the first measurement result obtained from the at least one second measurement result will be exemplarily described.
[0129]
Example 1: When the first measurement result is cell-level and the second measurement result is beam level, for example, Mn = one second measurement result among multiple second measurement results, or Mn = multiple second measurement results The average of the results.
[0130]
Example 2: When the first measurement result is the cell level and the second measurement result is the position level, for example, Mn=one second measurement result among multiple second measurement results, or Mn=multiple second measurement results average of. For another example, for a beam of the first cell, the UE selects one of multiple second measurement results corresponding to the beam or combines the multiple second measurement results according to the QCL relationship between the SSBs corresponding to the first cell to obtain Corresponding to the third measurement result (beam level) of the beam, Mn is obtained according to the multiple third measurement results corresponding to different beams, specifically, Mn=a third measurement result among the multiple third measurement results, or Mn= The average of multiple third measurement results.
[0131]
Example 3: When the first measurement result is beam-level and the second measurement result is beam level, then Mn=the second measurement result, which is the same as the beam corresponding to the first measurement result.
[0132]
Example 4: When the first measurement result is beam-level and the second measurement result is position level, for example, for a beam of the first cell, the UE selects multiple channels according to the QCL relationship between the SSBs corresponding to the first cell. One of the second measurement results of the two corresponding beams or the combination of the multiple second measurement results to obtain the third measurement result of the corresponding beam (beam level), that is, the same as the processing for one beam in Example 2, Mn = The third measurement result, thereby obtaining the first measurement result corresponding to the beam.
[0133]
Example 5: When the first measurement result is the position level, and the second measurement result is the position level, then Mn=the second measurement result, and the second measurement result is the same as the position corresponding to the first measurement result.
[0134]
For example, the second measurement result may be level of the SSB time domain location, the second measurement result may include multiple second measurement results corresponding to different SSB time domain locations, and multiple second measurement results may be selected according to the QCL relationship between the SSBs corresponding to the first cell. One of the two measurement results or multiple second measurement results are combined, and the first measurement result is obtained according to the selected second measurement result or the combined result.
[0135]
In this embodiment, different SSB time domain positions corresponding to multiple second measurement results may correspond to the same beam, that is, multiple second measurement results may correspond to the same beam.
[0136]
For example, since the L1filtering measurement value SS-RSRP as the second measurement result corresponds to the time domain position, and the SSBs of multiple time domain positions in a window may correspond to the same beam, the UE can pass the per Select or combine the SS-RSRP of position (corresponding to the time domain position) to obtain the SS-RSRP' of the per beam (beam level), and then obtain the cell-level and/or beam according to the SS-RSRP' of the per beam The beam-level L3 filtering measurement result is the first measurement result.
[0137]
Above, the implementation method of step 201 has been exemplified.
[0138]
In step 202, the measurement information of the first cell is generated according to the first measurement result of the first cell. FIG. 6 is another schematic diagram of the method for implementing step 202 in Embodiment 1 of the present invention. As shown in Figure 6, step 202 includes:
[0139]
Step 601: Generate measurement information of the beam level of the first cell according to the first measurement result, where the first measurement result of the first cell is beam level, or,
[0140]
Step 602: According to the first measurement result and the QCL relationship between the SSB corresponding to the first cell, generate measurement information of the beam level of the first cell. The information includes the SSB time domain position index, and the two SSB time domain position indexes included in the measurement information correspond to different beams.
[0141]
In step 601, for example, the UE may notify the network of the measurement information of the beam level of a cell by reporting the first measurement result of the beam level and the beam index.
[0142]
In step 602, for example, the UE informs the network of the measurement information of the beam level of a cell by reporting the first measurement result of the SSB time domain position level and the SSB time domain position index, before reporting the measurement information , The UE generates measurement information according to the QCL relationship between the SSBs, where the two SSB time domain position indexes in the measurement information correspond to different beams.
[0143]
In addition, for multiple first measurement results corresponding to multiple SSB time-domain positions of a beam, one of the first measurement results can be selected or multiple first measurement results can be combined, based on the selected first measurement result or combined The result of generating the measurement information corresponding to one beam of the first cell.
[0144]
In step 203, the UE sends the measurement information to the network.
[0145]
For example, measurement information is included in MeasurementReport, and one MeasurementReport may include measurement information of multiple cells corresponding to the same MO.
[0146]
In this embodiment, at least one of the QCL relationship between the SSBs corresponding to the first cell and the SSB transmission restriction corresponding to the first cell is predefined or indicated by the network. Hereinafter, a specific and exemplary description will be given for the situation indicated by the network.
[0147]
As shown in Figure 2, the method may further include:
[0148]
Step 204: Receive indication information, where the indication information indicates at least one of the QCL relationship between the SSBs corresponding to the first cell and the SSB transmission restriction corresponding to the first cell.
[0149]
In this embodiment, the indication information may display or implicitly indicate at least one of the QCL relationship between the SSBs corresponding to the first cell and the SSB transmission restriction corresponding to the first cell.
[0150]
For example, the indication information includes first indication information indicating the QCL relationship between the SSBs corresponding to the first cell and/or second indication information indicating the SSB transmission restriction of the first cell,
[0151]
The first indication information includes: at least one of the number of beams in one window and the SSB group in one window;
[0152]
The second indication information includes: the specified number of SSBs to be sent in a window, the maximum number of SSBs to be sent, the time domain range for sending the SSB, and the specified number of SSBs corresponding to a beam and the maximum number of transmissions in a window At least one of them.
[0153]
In this embodiment, the number of beams in a window may also be referred to as the number of non-QCLed SSBs or the number of DMRS sequences.
[0154]
For example, the QCL relationship between SSBs can be determined according to the following formula (2) or (3):
[0155]
Beam index=mod(t, Q) (2)
[0156]

[0157]
Among them, t is the time domain position index of the candidate SSB in a window, Q1 is the number of consecutive candidate SSB time domain positions corresponding to the same beam, and Q1 is predefined or indicated by the network, for example, Q1=2.
[0158]
In this embodiment, the indication information may be sent by the first cell or by the second cell.
[0159]
In this embodiment, the first cell may be a serving cell or a non-serving cell of the UE, for example, a cell listed in the MO or a cell not listed in the MO but detected by the UE. The second cell may be a serving cell of the UE.
[0160]
For example, the indication information is sent through at least one of physical broadcast channel (PBCH), MAC signaling, and system information.
[0161]
In this case, the indication information may also be used for the UE to send and receive other signals and/or channels in the first cell.
[0162]
In this embodiment, when the indication information is sent by the first cell, the indication information is only used for the measurement of the first cell, or the indication information may also be used for the SSB-based measurement of the second cell, and the second The frequency domain position of the SSB of the cell and the SSB of the first cell are the same as the SCS.
[0163]
For another example, the indication information is sent through RRC signaling. For example, the RRC signaling is dedicated RRC signaling, for example, sent through RRCReconfiguration.
[0164]
In this case, the indication information may be MO-specific (per MO, that is MO-specific) or cell-specific (per cell, that is cell-specific). In addition, it can be used for measurement configurations of intra-frequency measurement and inter-frequency measurement.
[0165]
For example, for the case where the indication information is MO specific, that is, one indication information corresponds to one MO, or in other words, an indication information is included in an MO, and the cell identity associated with the indication information is not specified, the indication information is applicable to the UE The cell corresponding to the MO is measured, and the cell corresponding to the MO refers to the cell that sends the SSB at the time-frequency domain position indicated by the MO and the SCS. In this way, when the first cell is one of the cells corresponding to the MO, after receiving the indication information, the UE can determine the QCL relationship between the SSBs corresponding to the first cell according to the indication information.
[0166]
For the case where the indication information is cell-specific, that is, one indication information corresponds to one cell. For example, one MO includes cell identities and associated indication information of multiple cells (listed cells). When the first cell is one of the multiple cells listed, the UE learns the QCL relationship between the SSBs corresponding to the first cell according to the indication information corresponding to the corresponding cell identifier.
[0167]
Compared with the cell-specific indication mode, the MO-specific indication mode can reduce the signaling overhead. Compared with the MO-specific indication mode, if the QCL relationship between the SSBs of different cells corresponding to the same MO is different, the cell-specific indication mode can help the UE to improve the measurement accuracy.
[0168]
In addition, an MO may also include one MO-specific indication information and one or more cell-specific indication information. When the first cell is the cell corresponding to the MO, but is not the listed cell, in the case that there is no cell-specific indication information, the indication is performed according to the MO-specific indication information.
[0169]
In this embodiment, the QCL relationship between the SSBs corresponding to the first cell may be indicated by the sequence in the SSB of the first cell.
[0170]
For example, it is indicated by the DMRS sequence in the SSB. When the first cell transmits the SSB, when the two SSBs are QCL, the two SSBs use the same DMRS sequence, and the two SSBs may be SSBs in the same window or different windows. In this way, the UE can determine the QCL relationship between the SSBs by detecting the DMRS in the SSB. When the DRMS ​​sequences of two SSBs are the same, the two SSBs are considered to be QCL. The SSB here is the SSB detected by the UE.
[0171]
In this embodiment, when the UE receives the indication information corresponding to the first cell sent by the second cell, and also receives the indication information corresponding to the first cell sent by the first cell, the UE follows the indication sent by the first cell Information is measured based on SSB.
[0172]
It can be seen from the above embodiment that the first cell’s first cell is obtained by at least one of the QCL relationship between the SSBs corresponding to the first cell, the SSB transmission restriction corresponding to the first cell, and the detection result of the SSB of the first cell. The measurement result, and the measurement information of the first cell is generated and reported according to the first measurement result, which can effectively improve the accuracy of the SSB-based measurement report and reduce the complexity and power consumption of the SSB-based measurement.
