Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a beam measurement method, measurement configuration method, apparatus, terminal, and network equipment. Background Technology

[0002] Currently, beam measurement in mobility measurement involves the base station configuring the terminal to perform measurements via RRC (Radio Resource Control). After receiving the measurement configuration, the terminal performs the measurement according to the configuration and obtains the results. If the terminal uses an event-driven approach to report the measurement results, it determines whether the event-driven conditions are met based on the measurement results. These conditions are configured by the base station. When the terminal detects that the measurement results meet the event-driven conditions, it reports the measurement results. However, existing beam measurement reporting in mobility measurement is at Layer 3 (L3), resulting in significant latency and making it unsuitable for beam management in fast-moving scenarios.

The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

All of these systems include terminal equipment and network equipment. The systems may also include a core network component, such as Evolved Packet System (EPS) and 5G system (5GS).

Depending on the configuration and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, and can also be diversity transmission, precoding transmission, or beamforming transmission, etc.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone.

[0182] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0183] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0184] The beam measurement reporting process in mobility measurement is as follows:

[0185] Step 1: The base station configures the terminal to perform measurements via RRC signaling. The configured parameters include:

[0186] a) Measurement Object: The reference signal information provided to the terminal for measurement. The reference signals that can be measured are the Synchronization Signal and PBCH block (SSB) and / or the single-port periodic Channel State Information Reference Signal (CSI-RS).

[0187] b) The reporting configuration indicates which measurement quantity the terminal needs to measure and report (such as Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), or Signal-to-Noise and Interference Ratio (SINR)). It also configures whether the terminal reports measurement results event-driven or periodically. The measurement ID (measId) contains a pointer that associates a reporting configuration with a Measurement Object.

[0188] c) The quantityConfig specifies the L3 filter coefficients used to filter the measurements. A single measconfig can contain a maximum of two quantityConfigs.

[0189] For example, the base station notifies the terminal via the `measObject` parameter under `MeasObjectToAddMod` in the RRC class that the reference signal for measurement is the SSB, with a frequency of 504900. The subcarrier spacing of this SSB is 30kHz. The base station also defines a 5-subframe measurement window with a period of 20ms. The `ReportConfigToAddMod` parameter in the RRC class includes two `reportConfig` values: `reportConfigId 1` and `reportConfigId 2`. Under `reportConfigId 1`, the base station instructs the terminal to report the RSRP measurement, using an event-driven reporting method. The event-driven condition is `event A3` (event A3: Neighbor becomes amount of offset better than PCell / PSCell). `maxReportCells` indicates that a maximum of 3 cells' RSRP values ​​can be reported. `timeToTrigger` indicates that the terminal will report RSRP 320ms after the `event A3` condition is met. The time interval between two reports (`reportinterval`) is 1024ms.

[0190] Step 2: After receiving the measurement configuration, the terminal performs measurements according to the configuration and obtains the measurement results. The measurement model for obtaining cell-level and beam-level measurement results is as follows: Figure 1 As shown.

[0191] At point A, the terminal measures the beams of a certain cell using the resources configured by the base station in the MO and obtains measurement results beam1, beam2, …, beam K. At point A1, the terminal performs layer 1 filtering on the measurement results obtained at point A. Then, the terminal compares the measurement values after layer 1 filtering with a certain threshold configured by the base station to obtain the cell-level measurement result (point B). If the RRC configures the beam selection threshold Threshold, the maximum beam N when obtaining the cell-level measurement result, and there are n (n < N) beams among the beams detected by the UE whose quality is not lower than the configured threshold Threshold, then the cell-level measurement result is equal to the linear average of the measurement results corresponding to these n best beams greater than Threshold. If the quality of the best beam among the beams detected by the UE is lower than the configured threshold Threshold, then the cell-level measurement result is equal to the measurement result corresponding to the best beam detected by the UE. After point B, the terminal performs L3 filtering on the cell-level measurement result to obtain the signal quality of each cell (point C). The terminal compares the cell-level measurement result with the conditions in the reporting criterion. If the reporting criterion is met (such as Event A3: the measurement result of the neighboring cell is better than a certain amount (offset) of the special cell (primary serving cell (PCell) / primary serving cell of the secondary cell group (PSCell))), the terminal performs cell-level measurement reporting.

[0192] Meanwhile, if the terminal is configured to report the beam-level measurement results (IncludeBeamMeasurements included in reportConfig is true), the terminal needs to report the beam-level measurement results. As Figure 2 shown in the lower part, after the terminal performs L3 filtering on the measurement results of K beams in a certain cell (point E), it selects X beams greater than the pre-configured threshold absThreshSS-BlocksConsolidation and reports their indices (SSB resource indicator (SSBRI) / CSI-RS resource indicator (CRI)) and the corresponding beam quality (RSRP / RSRQ / SINR) ( Figure 2 point F in

[0193] Step 3: When the terminal reports measurement results using an event-driven approach, the terminal determines whether the event-driven conditions are met based on the measurement results. These conditions are configured by the base station. When the terminal detects that the measurement results meet the event-driven conditions, such as a cell-level RSRP value exceeding a certain threshold for a sustained period (TimeToTrigger), the terminal reports the measurement results. When reporting the measurement results, the terminal first sends a Scheduling Request (SR) to request uplink resources. Upon receiving this request, the base station sends an Uplink Grant (UL grant) to allocate Physical Uplink Shared Channel (PUSCH) resources. The terminal then transmits the beam measurement results on the PUSCH resources indicated by the UL grant.

[0194] Current mobility measurement reporting is at Level 3, resulting in significant latency and making it unsuitable for beam management in fast-moving scenarios. This application provides a beam measurement method, beam configuration method, apparatus, terminal, and network device to address these issues.

[0195] The beam measurement method, apparatus, and terminal are based on the same application concept, as are the beam configuration method, apparatus, and network equipment. Furthermore, the beam measurement method and beam configuration method are implemented by different entities under the same concept, and their problem-solving principles are similar. Therefore, the various embodiments can be referred to each other, and repeated details will not be elaborated further.

[0196] like Figure 2 As shown, an embodiment of the present invention provides a beam measurement method, including:

[0197] Step 21: The terminal receives resource configuration information for beam measurement sent by the network device; wherein the resource configuration information includes beam measurement resources and first information.

[0198] The first information includes at least one of the following:

[0199] Parameters of the physical cell identifier list;

[0200] Indication information associated with the physical cell identifier;

[0201] The first index of the beam measurement resource implicitly indicates the physical cell identifier.

[0202] For example: If the first information includes parameters of a list of physical cell identifiers, this first information can instruct the terminal to perform beam measurement and beam quality assessment on the cells included in the parameters. As another example: If the first information includes indicator information associated with physical cell identifiers, each beam measurement resource corresponds to one indicator, meaning the physical cell identifier of the beam measurement cell is implicitly indicated through the indicator information corresponding to that beam measurement resource. As yet another example: If the first information includes a first index of the beam measurement resource, the network device side and the terminal side can determine the physical cell identifier corresponding to the beam measurement resource based on system preset rules, thus determining the cell to be measured; that is, the physical cell identifier is implicitly indicated through the first index of the beam measurement resource.

[0203] Step 22: The terminal performs beam measurement based on the beam measurement resources and the first information.

[0204] In this embodiment, the terminal receives resource configuration information for beam measurement sent by the network device, and the resource configuration information includes beam measurement resources and first information. The terminal performs beam measurement based on the beam measurement resources and the first information. The first information includes parameters of a physical cell identifier list, indication information associated with physical cell identifiers, and a first index of the beam measurement resources. The first index implicitly indicates the physical cell identifier, thereby realizing beam measurement for L1 / L2 inter-cell beam management. This solves the problem of large beam measurement reporting delays in existing mobility measurement methods, making them unsuitable for beam management in fast-moving scenarios.

[0205] Optionally, step 21 may specifically include: the terminal receiving a third RRC signaling sent by the network device; wherein the third RRC signaling carries the beam measurement resources and parameters of the physical cell identifier list.

[0206] Optionally, step 22 may specifically include:

[0207] The terminal determines the cell to be used for beam measurement based on the parameters of the physical cell identifier list;

[0208] The terminal performs beam measurement on the cell using the beam measurement resources.

[0209] For example, this resource configuration information is used to instruct the terminal to perform beam measurement and beam quality assessment on the cell list {PCI1, PCI2, PCI3} contained in the parameters, and the resource for beam measurement is the resource set {SSB1, SSB2, SSB3, SSB4}. Then, the terminal performs measurement on the beams in the cell list {PCI1, PCI2, PCI3} on the measurement resource {SSB1, SSB2, SSB3, SSB4} according to the base station's instructions.

[0210] Optionally, step 21 may specifically include: the terminal receiving a second RRC signaling sent by the network device; wherein the second RRC signaling carries the beam measurement resource and the indication information corresponding to the beam measurement resource.

[0211] Optionally, step 22 may specifically include:

[0212] The terminal determines the cell corresponding to the beam measurement resource for beam measurement based on the beam measurement resource and the indication information corresponding to the beam measurement resource;

[0213] The terminal performs beam measurement on the cell using the beam measurement resources.

[0214] For example, the resource configuration information used to instruct the terminal to perform beam measurement uses a resource set {SSB1+indicator1, SSB2+indicator2, SSB3+indicator3, SSB4+indicator4}. Each SSB resource carries an indicator, which is associated with a physical cell identifier. Based on this association, the physical cell identifier associated with the indicator for each beam measurement resource can be determined, thus identifying the physical cell identifier corresponding to each beam measurement resource. This allows the terminal to perform beam measurement on the corresponding beam measurement resource using the beam measurement cell corresponding to the physical cell identifier.

[0215] The association (or mapping) between the indicator and the physical cell identifier can be configured and updated through the first MAC-CE signaling.

[0216] Optionally, the beam measurement method further includes:

[0217] The terminal receives a first Media Access Control-Equipment (MAC-CE) signaling message sent by the network device; wherein the first MAC-CE signaling message carries the mapping relationship between the indication information associated with the physical cell identifier and the physical cell identifier;

[0218] The terminal determines the cell corresponding to the beam measurement resource for beam measurement based on the mapping relationship between the indication information and the physical cell identifier.

[0219] The terminal performs beam measurement on the cell using the beam measurement resources.

[0220] For example, at time n, the network device can configure the mapping relationship between the indicator and the physical cell identifier through the first MAC-CE signaling. Thus, the terminal can determine the physical cell identifier corresponding to each measurement resource based on the configured mapping relationship between the indicator and the physical cell identifier, the beam measurement resources configured by the network device and their corresponding indicators, that is, determine the physical cell identifier corresponding to each beam measurement resource. Thus, the terminal can perform beam measurement on the corresponding beam measurement resource for the beam measurement cell corresponding to the physical cell identifier.

[0221] At time n+k, the network device can update the mapping relationship between the indicator and the physical cell identifier through the first MAC-CE signaling. Thus, the terminal can determine the physical cell identifier corresponding to each measurement resource based on the updated mapping relationship between the indicator and the physical cell identifier, the beam measurement resources configured by the network device and their corresponding indicators, i.e., determine the physical cell identifier corresponding to each beam measurement resource. Thus, the terminal can perform beam measurement on the corresponding beam measurement resource for the beam measurement cell corresponding to the physical cell identifier.

[0222] The association (or mapping) between the indicator and the physical cell identifier can be configured through the first RRC signaling and updated through the first MAC-CE signaling.

[0223] Optionally, the beam measurement method further includes:

[0224] The terminal receives a first RRC signaling sent by the network device; and / or, the terminal receives a second MAC-CE signaling sent by the network device; wherein, the first RRC signaling is used to configure the mapping relationship between the indication information and the physical cell identifier; and the second MAC-CE signaling is used to update the mapping relationship between the indication information and the physical cell identifier.

[0225] The terminal determines the cell corresponding to the beam measurement resource for beam measurement based on the first RRC signaling, and performs beam measurement on the cell on the beam measurement resource; or, the terminal determines the cell corresponding to the beam measurement resource for beam measurement based on the second MAC-CE signaling, and performs beam measurement on the cell on the beam measurement resource.

[0226] For example, at time n, the network device can configure the mapping relationship between the indicator and the physical cell identifier through the first RRC signaling. Thus, the terminal can determine the physical cell identifier corresponding to each measurement resource based on the configured mapping relationship between the indicator and the physical cell identifier, the beam measurement resources configured by the network device and their corresponding indicators, that is, determine the physical cell identifier corresponding to each beam measurement resource. Thus, the terminal can perform beam measurement on the corresponding beam measurement resource for the beam measurement cell corresponding to the physical cell identifier.

[0227] At time n+k, the network device can update the mapping relationship between the indicator and the physical cell identifier through the second MAC-CE signaling. Thus, the terminal can determine the physical cell identifier corresponding to each measurement resource based on the updated mapping relationship between the indicator and the physical cell identifier, the beam measurement resources configured by the network device and their corresponding indicators, that is, determine the physical cell identifier corresponding to each beam measurement resource. Thus, the terminal can perform beam measurement on the corresponding beam measurement resource for the beam measurement cell corresponding to the physical cell identifier.

[0228] Optionally, step 21 may specifically include: the terminal receiving a fourth RRC signaling sent by the network device, the fourth RRC signaling carrying the beam measurement resource and a first index of the beam measurement resource.

[0229] Optionally, step 22 may specifically include:

[0230] The terminal determines the beam measurement resources corresponding to the physical cell identifiers based on the first index of the beam measurement resources.

[0231] The terminal performs beam measurement on the corresponding beam measurement resources for the cell corresponding to the physical cell identifier.

[0232] Optionally, the method may further include:

[0233] The terminal determines the second index of the beam measurement resources corresponding to the physical cell identifiers according to the system's predefined rules;

[0234] The terminal sends the beam measurement result corresponding to the second index to the network device.

[0235] For example, by predefining or preconfiguring the system, a first index implicitly indicates the physical cell identifier. The terminal can then determine the beam measurement resources corresponding to each physical cell identifier based on the first index, and perform beam measurement on the corresponding beam measurement resources for each cell. Furthermore, the terminal re-encodes the beam measurement resources corresponding to the beam measurement cells based on predefined system rules. Specifically, the terminal determines a second index for the beam measurement resources corresponding to each physical cell identifier based on these rules, and reports the beam measurement results to the network device based on this second index (i.e., sends the beam measurement results corresponding to the second index to the network device). At this time, the network device can also determine the second index for the beam measurement resources corresponding to each physical cell identifier based on the predefined system rules, and obtain the corresponding beam measurement results based on the second index.

[0236] Optionally, the beam measurement method further includes:

[0237] The terminal receives beam measurement reporting configuration information sent by the network device;

[0238] The terminal sends the beam measurement results obtained from the beam measurement to the network device based on the beam measurement reporting configuration information.

[0239] The beam measurement reporting configuration information includes:

[0240] Reporting of event-driven beam measurement results;

[0241] Offset of the parameter value that triggered the event;

[0242] Information related to the reporting of event-driven beam measurement results.

[0243] Event-driven beam measurement result reporting can be understood as the terminal reporting beam measurement results when event triggering conditions are met. For example, network devices can configure CSI-ReportConfig via RRC to instruct the terminal to use an event-driven beam measurement result reporting method. This instruction can be achieved by adding the eventTriggered option to reportConfigType in CSI-ReportConfig.

[0244] The parameter value offset of the triggering event can be carried in the higher-layer signaling.

[0245] Optionally, the terminal sends the beam measurement results obtained from the beam measurement to the network device according to the beam measurement reporting configuration information, including:

[0246] Based on the beam measurement results obtained from beam measurement, determine the difference between the beam quality of the neighboring cell and the beam quality of the serving cell;

[0247] If the difference is greater than the offset of the parameter value that triggered the event, the terminal sends the beam measurement result obtained by the beam measurement to the network device.

[0248] Specifically, when the terminal performs beam measurement according to the network device configuration, the terminal determines whether the beam measurement result meets the conditions for triggering an event. If the conditions are met, the terminal reports the beam measurement results obtained after the beam measurement to the network device. For example, the beam measurement result of a neighboring cell (such as the linear average of the L1-RSRP of a set of beams) is better than a certain offset of the primary / serving cell. The value of this offset can be indicated to the terminal by the network device through higher-layer signaling, such as the M-offset parameter included in the EventTriggerConfig mentioned above.

[0249] The relevant information reported in the event-driven beam measurement results report includes at least one of the following: the measurement reporting time interval when the event is triggered, the number of beam measurement reports when the event is triggered, the reporting amount when the event is triggered, and the maximum number of reporting cells supported by the event-triggered reporting.

[0250] Specifically, the terminal can send the beam measurement results obtained from the beam measurement to the network device according to at least one of the following: the measurement reporting time interval when the event is triggered, the number of beam measurement reports when the event is triggered, the reporting amount when the event is triggered, and the maximum number of reporting cells supported by the event-triggered reporting.

[0251] Optionally, the terminal sends the beam measurement results obtained from the beam measurement to the network device, including at least one of the following:

[0252] The terminal sends uplink control information (UCI) to the network device; wherein the UCI carries the beam measurement results; that is, the beam measurement report is reported using the UCI method.

[0253] The terminal sends a third MAC-CE signaling message to the network device; wherein the third MAC-CE signaling message carries the beam measurement result; that is, the beam measurement result is reported using the MAC-CE method.

[0254] The terminal sends the beam measurement results to the network device through the uplink channel reserved by the network device for configuration authorization; that is, it reports the beam measurement report using the UL Configured Grant method.

[0255] The terminal sends the beam measurement results to the network device through the Contention-Free Random Access (CFRA) uplink channel; that is, it reports the beam measurement results using the CFRA method.

[0256] The terminal sends the beam measurement results to the network device through a contention-based random access (CBRA) uplink channel; that is, it reports the beam measurement results using the CBRA method.

[0257] The terminal sending a UCI to the network device includes:

[0258] The terminal sends a scheduling request (SR) to the network device requesting the allocation of uplink resources;

[0259] The terminal receives an uplink license (UL grant) sent by the network device; wherein the UL grant carries uplink resources allocated by the network device to the terminal;

[0260] Wherein, if the SR carries the number of requested resources, the uplink resources are determined based on the number of requested resources; if the SR does not carry the number of requested resources, the uplink resources are determined based on the maximum number of uplink resources required by the terminal report.

[0261] Specifically, the terminal sends SRs and the number of reports on the PUCCH, requesting the base station to allocate uplink resources. The base station allocates uplink resources according to the terminal's request and notifies the terminal of the allocated uplink resources via UL grant. If the terminal's request does not include the number of reports, the base station allocates uplink resources according to the maximum number of uplink resources required by the terminal's reports.

[0262] Optionally, the terminal sends a third MAC-CE signaling message to the network device, including:

[0263] If a PUSCH resource exists, the terminal sends the third MAC-CE signaling on the PUSCH resource.

[0264] Specifically, similar to BFR MAC-CE reporting, a new MAC-CE can be defined, such as an Inter-Cell Beam Management (ICBM) MAC-CE. The terminal transmits the ICBMMAC-CE on the most recently available PUSCH resource. If the terminal cannot find such a PUSCH resource, it sends an SR on the PUCCH to request the base station to allocate uplink resources. The base station allocates uplink resources according to the terminal's request and issues a UL grant to notify the terminal of the allocated uplink resources.

[0265] The terminal sends the beam measurement results to the network device through the uplink channel of CFRA / CBRA, which may include reporting the measurement results using the Physical Random Access Channel (PRACH), such as through MSG3.

[0368] The processor executes any of the methods described in the embodiments of this application according to the obtained executable instructions by calling a computer program stored in memory. The processor and memory may also be physically separated.

[0369] It should be noted that the apparatus provided in this embodiment of the invention can implement all the method steps implemented in the above method embodiment and can achieve the same technical effect. Therefore, the parts and beneficial effects that are the same as those in the method embodiment will not be described in detail here.

[0372] The beam measurement method of this invention has been described above from the perspective of the terminal side. The measurement configuration method on the network device side will be further explained below with reference to the accompanying drawings.

[0373] like Figure 5 As shown, an embodiment of the present invention provides a measurement configuration method, including:

[0374] Step 51: The network device sends resource configuration information for beam measurement to the terminal; wherein, the resource configuration information includes beam measurement resources and first information;

[0375] The first information includes at least one of the following:

[0376] Parameters of the physical cell identifier list;

[0377] Indication information associated with the physical cell identifier;

[0378] The first index of the beam measurement resource implicitly indicates the physical cell identifier.

[0379] For example, network devices can configure CSI-ResourceConfig via RRC to instruct the terminal on the reference signal resources (such as SSB / CSI-RS) for beam measurement and the first information.

[0380] In this embodiment, the network device sends resource configuration information for beam measurement to the terminal, and the resource configuration information includes beam measurement resources and first information. The first information includes parameters of a physical cell identifier list, indication information associated with physical cell identifiers, and a first index of the beam measurement resources. The first index implicitly indicates the physical cell identifier. Thus, the terminal performs beam measurement based on the beam measurement resources and the first information, thereby realizing beam measurement for Layer 1 (L1) / Layer 2 (L2) inter-cell beam management. This solves the problem of large beam measurement reporting delays in existing mobility measurement methods, making them unsuitable for beam management in fast-moving scenarios.

[0494] This invention also provides a processor-readable storage medium storing a computer program that enables the processor to execute the steps in the above-described measurement configuration method, achieving the same technical effect. The parts and beneficial effects identical to those in the method embodiments will not be described in detail here.

[0495] The processor-readable storage medium can be any available medium or data storage device that the processor can access, including but not limited to magnetic memory (e.g., floppy disk, hard disk, magnetic tape, magneto-optical disk (MO)), optical memory (e.g., CD, DVD, BD, HVD), and semiconductor memory (e.g., ROM, EPROM, EEPROM, non-volatile memory (NAND FLASH), solid-state drive (SSD)).

[0496] The measurement configuration method on the network device side and the beam measurement method on the terminal side of the present invention will be described below with reference to specific embodiments:

[0497] Example 1:

[0498] Network devices (such as base stations) configure CSI-ReportConfig and CSI-ResourceConfig via RRC. CSI-ResourceConfig contains a cell list {PCI1, PCI2, PCI3}, instructing the terminal to measure the measurement resources in the cell list {PCI1, PCI2, PCI3}. The resources for beam measurement are the resource set {SSB1, SSB2, SSB3, SSB4}. At the same time, it instructs the terminal to use an event-driven reporting method for reporting beam measurement results (SSBRI+L1-RSRP+PCI), and the condition for triggering event-driven reporting is that the beam measurement results of neighboring cells are better than those of the serving cell by 3dB. The base station configures the maximum number of beams that the terminal can report to be 4.

[0499] The terminal receives base station configuration information and, according to the base station's instructions, performs measurements on measurement resources {SSB1, SSB2, SSB3, SSB4} for the beams in the cell list {PCI1, PCI2, PCI3}. The measurement results are as follows:

[0500] PCI1: L1-RSRP1_1, L1-RSRP1_2, L1-RSRP1_3, L1-RSRP1_4;

[0501] PCI2: L1-RSRP2_1, L1-RSRP2_2, L1-RSRP2_3, L1-RSRP2_4;

[0502] PCI3: L1-RSRP3_1, L1-RSRP3_2, L1-RSRP3_3, L1-RSRP3_4;

[0503] The terminal selects measurement results and linearly averages the L1-RSRP values ​​that are greater than a preset threshold Threshold_RSRP to obtain the measurement results for each cell as follows:

[0504] PCI1: L1-RSRP1_Avg;

[0505] PCI2: L1-RSRP2_Avg;

[0506] PCI3: L1-RSRP3_Avg;

[0507] The terminal compares the beam quality of the serving cell (PCI1) with the beam quality of neighboring cells (PCI2, PCI3) and determines that L1-RSRP2_Avg – L1-RSRP1_Avg is greater than 3dB, thus satisfying the event triggering condition. L1-RSRP3_Avg – L1-RSRP1_Avg is less than 3dB.

[0508] The terminal sends a Service Request (SR) on the PUCCH, requesting the base station to allocate uplink PUSCH resources. The base station allocates uplink resources according to the terminal's request and notifies the terminal of the allocated PUSCH resources via UL grant. The terminal then transmits beam measurement results on the PUSCH resources allocated by the base station.

[0509] {SSBRI1+L1-RSRP2_1+PCI2,SSBRI2+L1-RSRP2_2+PCI2,SSBRI3+L1-RSRP3_2+PCI2,SSBRI4+L1-RSRP2_4+PCI2}.

[0510] The terminal uses the MAC-CE reporting method. In this case, the terminal can transmit Inter-Cell Beam Management (ICBM) MAC-CE on the most recently available PUSCH resource. The ICBM MAC-CE carries the beam measurement results {SSBRI1+L1-RSRP2_1,SSBRI2+L1-RSRP2_2,SSBRI3+L1-RSRP3_2,SSBRI4+L1-RSRP2_4}+PCI2. If the terminal cannot find such a PUSCH resource, it sends an SR on the PUCCH to request the base station to allocate uplink resources. The base station allocates uplink resources according to the terminal's request and sends a UL grant notification to the terminal regarding the allocated PUSCH resources. The terminal then transmits the beam measurement results {SSBRI1+L1-RSRP2_1,SSBRI2+L1-RSRP2_2,SSBRI3+L1-RSRP3_2,SSBRI4+L1-RSRP2_4}+PCI2 on the PUSCH resource allocated by the base station.

[0511] Example 2:

[0512] Network devices (such as base stations) configure CSI-ReportConfig and CSI-ResourceConfig via RRC. CSI-ResourceConfig contains a cell list {PCI1, PCI2, PCI3}, instructing the terminal to measure the measurement resources in the cell list {PCI1, PCI2, PCI3}. The resources for beam measurement are the resource set {SSB1, SSB2, SSB3, SSB4}. Simultaneously, it instructs the terminal to report beam measurement results (SSBRI+L1-RSRP+indicator) using an event-driven reporting method, triggered by a neighboring cell's beam measurement result being 3dB better than the serving cell's. The base station configures the maximum number of beams the terminal can report to be 4. The correspondence between the indicator (i.e., indication information) and PCIs can be implemented by the system through predefined methods. An example of an indicator-PCI correspondence is shown in Table 1.

[0513] Table 1

[0514] Indicator1(00) PCI1 Indicator2(01) PCI2 Indicator3(11) PCI3

[0515] The terminal receives base station configuration information and, according to the base station's instructions, performs measurements on measurement resources {SSB1, SSB2, SSB3, SSB4} for the beams in the cell list {PCI1, PCI2, PCI3}. The measurement results are as follows:

[0516] PCI1: L1-RSRP1_1, L1-RSRP1_2, L1-RSRP1_3, L1-RSRP1_4;

[0517] PCI2: L1-RSRP2_1, L1-RSRP2_2, L1-RSRP2_3, L1-RSRP2_4;

[0518] PCI3: L1-RSRP3_1, L1-RSRP3_2, L1-RSRP3_3, L1-RSRP3_4;

[0519] The terminal selects measurement results and linearly averages the L1-RSRP values ​​that are greater than a preset threshold Threshold_RSRP to obtain the measurement results for each cell as follows:

[0520] PCI1: L1-RSRP1_Avg;

[0521] PCI2: L1-RSRP2_Avg;

[0522] PCI3: L1-RSRP3_Avg;

[0523] The terminal compares the beam quality of the serving cell (PCI1) with the beam quality of neighboring cells (PCI2, PCI3) and determines that L1-RSRP2_Avg – L1-RSRP1_Avg is greater than 3dB, thus satisfying the event triggering condition. L1-RSRP3_Avg – L1-RSRP1_Avg is less than 3dB.

[0524] The terminal sends a Service Request (SR) on the PUCCH, requesting the base station to allocate uplink PUSCH resources. The base station allocates uplink resources according to the terminal's request and notifies the terminal of the allocated PUSCH resources via UL grant. The terminal then transmits beam measurement results on the PUSCH resources allocated by the base station.

[0525] {SSBRI1+L1-RSRP2_1+Indicator2,SSBRI2+L1-RSRP2_2+Indicator2,SSBRI3+L1-RSRP3_2+Indicator2,SSBRI4+L1-RSRP2_4+Indicator2}.

[0526] The terminal uses the MAC-CE reporting method. At this time, the terminal transmits an ICBM MAC-CE on the most recently available PUSCH resource. The ICBM MAC-CE carries the beam measurement results: {SSBRI1+L1-RSRP2_1+Indicator2,SSBRI2+L1-RSRP2_2+Indicator2,SSBRI3+L1-RSRP3_2+Indicator2,SSBRI4+L1-RSRP2_4+Indicator2}. If the terminal cannot find such a PUSCH resource, it sends an SR on the PUCCH to request the base station to allocate uplink resources. The base station allocates uplink resources according to the terminal's request and sends a UL grant notification to the terminal regarding the allocated PUSCH resources. The terminal transmits beam measurement results {SSBRI1+L1-RSRP2_1+Indicator2,SSBRI2+L1-RSRP2_2+Indicator2,SSBRI3+L1-RSRP3_2+Indicator2,SSBRI4+L1-RSRP2_4+Indicator2} on the PUSCH resources allocated by the base station.

[0527] Example 3:

[0528] Network devices (such as base stations) configure CSI-ReportConfig and CSI-ResourceConfig via RRC, indicating that the reference signal resources for beam measurement by the terminal are the resource set {SSB1+indicator1, SSB2+indicator1, SSB3+indicator1, SSB4+indicator1, SSB1+indicator2, SSB2+indicator2, SSB3+indicator2, SSB4+indicator2, SSB1+indicator3, SSB2+indicator3, SSB3+indicator3, SSB4+indicator3}. Each SSB resource carries an indicator (i.e., indication information). The indicator is associated with the physical cell ID, and the initial association is configured via RRC. The association between the indicator and the physical cell is dynamically updated via MAC-CE. For example, at time n, the mapping between an indicator and the physical cell ID is shown in Table 2.

[0529] Table 2

[0530] Indicator1(00) PCI1 Indicator2(01) PCI2 Indicator3(11) PCI3

[0531] At time n+K, the mapping relationship between the indicator and the physical cell is updated via MAC-CE, as shown in Table 3.

[0532] Table 3

[0533] Indicator1(00) PCI3 Indicator2(01) PCI2 Indicator3(11) PCI1

[0534] The terminal is instructed to use an event-driven reporting method for reporting beam measurement results (SSBRI+L1-RSRP+indicator), and the condition for triggering event-driven reporting is that the beam measurement results of the neighboring cell are better than those of the serving cell by 3dB. The maximum number of beams that the terminal can report is configured to be 4.

[0535] The terminal receives base station configuration information and performs measurements on measurement resources {SSB1, SSB2, SSB3, SSB4} at time n+K according to the base station's instructions. The measurement results are as follows:

[0536] PCI1: L1-RSRP1_1, L1-RSRP1_2;

[0537] PCI2: L1-RSRP2_1, L1-RSRP2_2, L1-RSRP2_3;

[0538] PCI3;L1-RSRP3_1, L1-RSRP3_3, L1-RSRP3_4;

[0539] The terminal compares the measurement results with the L1-RSRP value of a preset threshold Threshold_RSRP to obtain the measurement results for each cell:

[0540] PCI1: L1-RSRP1_1;

[0541] PCI2:L1-RSRP2_1,L1-RSRP2_3;

[0542] PCI3: L1-RSRP3_1;

[0543] The terminal linearly averages the beam measurement values ​​of each cell that are greater than a preset threshold to obtain the beam quality of each cell.

[0544] PCI1: L1-RSRP1_Avg.

[0545] PCI2: L1-RSRP2_Avg.

[0546] PCI3: L1-RSRP3_Avg.

[0547] The terminal compares the beam quality of the serving cell (PCI1) with the beam quality of neighboring cells (PCI2, PCI3) and determines that L1-RSRP3_Avg > L1-RSRP1_Avg > L1-RSRP2_Avg, and L1-RSRP3_Avg – L1-RSRP1_Avg is greater than 3dB, satisfying the event triggering condition. The terminal then determines the measurement reporting quantity as:

[0548] SSBRI1+L1-RSRP3_1+indicator 1, SSBRI1+L1-RSRP1_1+indicator3.

[0549] The terminal sends a request for uplink PUSCH resources on the PUCCH, requesting the base station to allocate uplink PUSCH resources, and requests that the base station allocate 2 PUSCH resources. Upon receiving the terminal's request, the base station allocates uplink resources according to the terminal's request and notifies the terminal of the allocated PUSCH resources via UL grant. The terminal then transmits beam measurement results on the PUSCH resources allocated by the base station.

[0550] {SSBRI1+L1-RSRP3_1+indicator 1,SSBRI1+L1-RSRP1_1+indicator 3}.

[0551] Terminals can also transmit beam measurement results on configured grant-based PUSCH resources.

[0552] Example 4:

[0553] The base station configures CSI-ReportConfig and CSI-ResourceConfig via RRC, instructing the terminal to use the resource set {SSB1, SSB2, SSB3, SSB4} as the reference signal resources for beam measurement. At the same time, the base station can implicitly instruct the terminal to perform beam measurement on cell identifiers PCI1, PCI2, and PCI3 based on this reference signal resource index. The reference signal resources to be measured are renumbered according to the system's predefined algorithm, as shown in Table 4.

[0554] Table 4

[0555]

[0556]

[0557] Meanwhile, the base station instructs the terminal to use an event-driven reporting method for reporting beam measurement results (SSBRI+L1-RSRP), and the condition for triggering event-driven reporting is that the beam measurement results of the neighboring cell are better than those of the serving cell by 3dB. The base station configures the maximum number of beams that the terminal can report to be 4.

[0558] The terminal receives base station configuration information and performs measurements on measurement resources {SSB1, SSB2, SSB3, ..., SSB12} according to the base station's instructions. The measurement results are as follows:

[0559] PCI1: L1-RSRP1_1, L1-RSRP1_2, L1-RSRP1_3, L1-RSRP1_4;
