Description

Technical Field

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

[0002] In the L1 / L2 triggered mobility (LTM) scheme, triggering events are defined to initiate terminal measurement reporting. The terminal performs beam measurements on the serving cell / candidate cell according to the base station's instructions. When the terminal finds that the measurement results meet the conditions defined in the indicated event, it triggers measurement reporting and reports the measurement results. After receiving the terminal's beam measurement results, the base station determines the target cell and indicates the target cell to the terminal. How the terminal determines the measurement resources of the candidate cell / current cell during this process is a crucial issue that needs to be addressed.

[0003] The current single-cell measurement resource indication method is not applicable to LTM. When there are multiple candidate cells, the reference signal type indicated by each candidate cell for LTM may be different. Therefore, the reference signal type of the serving cell may be the same as that of candidate cell 1 and different from that of candidate cell 2, which will lead to inaccurate measurement results reported by the terminal.

Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0184] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of this application. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0185] In the various embodiments of this application, it should be understood that the sequence number of each process described below does not imply the order of execution. 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 this application.

[0186] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0187] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0188] 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.

[0189] Embodiments of this application provide a beam measurement reporting method, apparatus, terminal, and network-side equipment to solve the problem that existing measurement resource determination methods result in inaccurate measurement results reported by the terminal.

[0190] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0191] like Figure 1 As shown, an embodiment of this application provides a beam measurement reporting method, applied to a terminal, specifically including the following steps:

[0192] Step 101: The terminal determines the reference signal measurement resources, which include at least one of the following: the reference signal measurement resources of the serving cell and the reference signal measurement resources of the candidate cell;

[0193] The reference signal measurement resources of the serving cell are determined based on the transmission configuration information sent by the network-side equipment, and the reference signal measurement resources of the candidate cell are determined based on the reference signal measurement resources of the serving cell.

[0194] Alternatively, the reference signal measurement resources of the candidate cell are determined based on the resource configuration information sent by the network-side equipment, and the reference signal measurement resources of the serving cell are determined based on the reference signal measurement resources of the candidate cell and the transmission configuration information sent by the network-side equipment.

[0195] In this embodiment, the network-side device can send transmission configuration information to the terminal, which includes relevant parameters for the terminal's transmission information. The terminal can determine the reference signal measurement resources of the serving cell based on this transmission configuration information.

[0196] When the reference signal measurement resources of the serving cell can be determined, the terminal can determine the reference signal measurement resources of the candidate cell based on the reference signal measurement resources of the serving cell. This ensures that the reference signal measurement resources of the serving cell and the candidate cell are of the same type.

[0197] Network-side equipment can send resource configuration information to the terminal. This resource configuration information can configure the type of reference signal measurement resources for candidate cells. The terminal can determine the reference signal measurement resources of the candidate cells based on this information. To ensure that the reference signal measurement resources of the serving cell are of the same type as those of the candidate cells, the terminal can determine the measurement resources of the serving cell based on the reference signal measurement resources of the candidate cells and the transmission configuration information sent by the network-side equipment. For example, if the QCL RS indicated in the transmission configuration information sent by the network-side equipment is a Phase-tracking Reference Signal (TRS), and the resource configuration information sent by the network-side equipment indicates that the type of reference signal measurement resources of the candidate cells is SSB, then the terminal can determine that the reference signal measurement resources of the serving cell are SSBs quasi-co-located with the TRS.

[0198] Step 102: Perform beam measurement based on the reference signal measurement resources to obtain the measurement results;

[0199] Step 103: If the trigger event is met, send the measurement results to the network-side device.

[0200] In this embodiment, after determining the reference signal measurement resources of the serving cell, the terminal measures the reference signal measurement resources of the serving cell to obtain measurement results; and / or, after determining the reference signal measurement resources of a candidate cell, the terminal measures the reference signal measurement resources of the candidate cell to obtain measurement results. When a triggering event is met, the terminal reports the measurement results to the network-side device. The triggering event can be one or more events; the terminal can report the measurement results when one triggering event is met, or it can report the measurement results when all triggering events are met.

[0201] In embodiments of this application, the terminal can determine the reference signal measurement resources of the serving cell based on the transmission configuration information sent by the network-side device, and determine the reference signal measurement resources of the candidate cell based on the reference signal measurement resources of the serving cell; or, it can determine the reference signal measurement resources of the candidate cell based on the resource configuration information sent by the network-side device, and determine the reference signal measurement resources of the serving cell based on the reference signal measurement resources of the candidate cell and the transmission configuration information sent by the network-side device, thereby ensuring that the reference signal measurement resource types of the serving cell and the candidate cell are the same, and thus ensuring the accuracy of the measurement results reported by the terminal.

[0202] As an optional embodiment, when the reference signal measurement resources of the serving cell are determined based on transmission configuration information sent by the network-side equipment, the transmission configuration information includes Transmission Configuration Indicator (TCI) status information, and determining the reference signal measurement resources includes:

[0203] The reference signal measurement resources of the serving cell are determined based on the quasi-co-located QCL reference signal RS contained in the TCI status information.

[0204] In this embodiment, the transmission configuration information sent by the network-side device includes TCI state information. This can be understood as the transmission configuration information including TCI state information, and may also include other transmission-related information; or it can be understood as the transmission configuration information being the TCI state information. The TCI state information includes QCL RS, and the reference signal measurement resource of the serving cell can be a QCL RS or an SSB quasi-co-located with the QCL RS.

[0205] As an optional embodiment, determining the reference signal measurement resources of the serving cell based on the quasi-co-located QCL reference signal RS included in the TCI state information includes:

[0206] The reference signal measurement resource for determining the serving cell is: the QCL RS contained in the TCI status information;

[0207] Alternatively, the reference signal measurement resource for the serving cell can be determined as: a synchronization signal block (SSB) that has a co-location relationship with the QCL RS contained in the TCI status information.

[0208] In this embodiment, the QCL RS includes at least one of the following: a CSI-RS for beam management, a CSI-RS for mobility management, or a TRS. For example, the TCI state can be a Channel State Information Reference Signal (CSI-RS), which is a TRS, a CSI-RS for mobility, or a CSI-RS for beam management. The reference signal measurement resource of the serving cell can be a QCL RS (such as a CSI-RS or a TRS) included in the TCI state, or the reference signal measurement resource of the serving cell can be a quasi-co-located SSB with a QCL RS included in the TCI state, such as a quasi-co-located SSB with a TRS.

[0209] As an optional embodiment, determining the reference signal measurement resources of the serving cell based on the quasi-co-located QCL reference signal RS included in the TCI state information includes:

[0210] When the network-side device sends at least two TCI status messages, the reference signal measurement resources of the serving cell are determined based on the QCL RS contained in the target TCI status message among the at least two TCI status messages; wherein, the target TCI status message is a predefined TCI status message, or the target TCI status message is determined based on the reference signal received power RSRP of the QCL RS.

[0211] In this embodiment, the network-side device may indicate two TCI state information to the terminal, such as in a Multi-Transmission Receiving Point (mTRP) scenario. In this case, the terminal can determine the reference signal measurement resources of the serving cell based on the QCL RS contained in a fixed TCI state information, for example, by determining the measurement resources of the serving cell based on the QCL RS contained in TCI state0 or TCI state1. When reporting measurement results to the network-side device, the terminal can report the TCI state used or the index of the reference signal measurement resources of the serving cell.

[0212] Alternatively, the terminal can determine the TCI state to use based on the RSRP value of the QCL RS among multiple TCI states indicated by the network side. For example, the RS corresponding to the minimum L1-RSRP value obtained from the QCL RS measurement can be used as the measurement resource of the serving cell, or the RS corresponding to the maximum L1-RSRP value obtained from the QCL RS measurement can be used as the measurement resource of the serving cell. When reporting measurement results to the network-side equipment, the terminal can report the TCI state used or the index of the serving cell reference signal measurement resource.

[0213] As an optional embodiment, when the reference signal measurement resources of the serving cell are determined based on the reference signal measurement resources of the candidate cells and the transmission configuration information sent by the network-side equipment, the determination of the reference signal measurement resources includes:

[0214] From the transmission configuration information sent by the network-side device, the measurement resource with the same reference signal measurement resource type as the candidate cell is determined to be the reference signal measurement resource of the serving cell.

[0215] In this embodiment, the reference signal measurement resources of the serving cell can also be determined based on the reference signal measurement resources of the candidate cell, thereby ensuring the consistency of the reference signal measurement resources between the serving cell and the candidate cell.

[0216] The network-side equipment configures transmission configuration information for the terminal. Based on the type of reference signal measurement resources (RSS) of the candidate cell, the terminal selects a measurement resource of the same type from the transmission configuration as the RSS of the serving cell. For example, if the transmission configuration information is a TCI state, and the QCL RS in this TCI state is either CSI-RS or TRS, and the RSS of the candidate cell is CSI-RS, then the terminal determines that the RSS of the serving cell is CSI-RS.

[0217] As an optional embodiment, when the reference signal measurement resources of the candidate cell are determined based on the reference signal measurement resources of the serving cell, the determination of the reference signal measurement resources includes:

[0218] Based on the type of reference signal measurement resources of the serving cell, an effective set of measurement resources is determined from at least one set of measurement resources associated with the candidate cell as the reference signal measurement resources of the candidate cell; wherein, the set of measurement resources of the same type as the reference signal measurement resources of the serving cell is effective.

[0219] In this embodiment, the reference signal measurement resources of a candidate cell can be determined based on the reference signal measurement resources of the serving cell. The network-side device can configure multiple associated measurement resource sets for the candidate cell, such as an SSB set (setting) composed of SSBs and a CSI-RS setting composed of CSI-RSs. If the terminal determines that the reference signal measurement resources of the serving cell are CSI-RS based on the transmission configuration information sent by the network-side device, then the reference signal measurement resources of the candidate cell can be determined to be the SSBs included in the SSB setting.

[0220] As an optional embodiment, when the reference signal measurement resources of the candidate cell are determined based on resource configuration information sent by the network-side equipment, the resource configuration information is used to configure the type of reference signal measurement resources of the candidate cell; determining the reference signal measurement resources includes:

[0221] Based on the type of reference signal measurement resources configured in the resource configuration information, an effective set of measurement resources is determined from at least one set of measurement resources associated with the candidate cell as the reference signal measurement resources of the candidate cell; wherein, the set of measurement resources of the same type as those configured in the resource configuration information is effective.

[0222] In this embodiment, the network-side device sends resource configuration information to the terminal, which may indicate the type of reference signal measurement resource. For example, the network-side device configures multiple associated measurement resource sets for a candidate cell, such as an SSB setting composed of SSBs and a CSI-RS setting composed of CSI-RSs. If the network-side device also indicates in the resource configuration information that the type of reference signal measurement resource is SSB, then the terminal determines that the reference signal measurement resource of the candidate cell is an SSB included in the SSB setting. Furthermore, the terminal can also determine that the reference signal measurement resource of the serving cell is a TRS quasi-co-located SSB indicated by the TCI state.

[0223] As an optional embodiment, the method further includes:

[0224] The device receives the measurement reporting configuration of candidate cells sent by the network-side equipment, and the measurement reporting configuration is carried through Radio Resource Control (RRC) messages;

[0225] Each candidate cell corresponds to a measurement reporting configuration, and each measurement reporting configuration is associated with at least two measurement resource sets;

[0226] Alternatively, each candidate cell may correspond to two measurement reporting configurations, and each measurement reporting configuration may be associated with a set of measurement resources.

[0227] Alternatively, each candidate cell corresponds to a measurement reporting configuration, and each measurement reporting configuration is associated with at least one set of measurement resources;

[0228] The measurement reporting configuration is configured by the network-side equipment for candidate cells.

[0229] In this embodiment, the network-side device can configure a measurement reporting configuration for candidate cells, send the measurement reporting configuration to the terminal via RRC, and configure the measurement resource set associated with the measurement reporting configuration. Each candidate cell can correspond to one or more measurement reporting configurations, and the measurement reporting configuration can be associated with one or more measurement resource sets.

[0230] For example, the network-side equipment indicates one measurement reporting configuration for each candidate cell. Each report configuration is associated with two or more reference signal measurement resource sets, such as the SSB resource set and the CSI-RS resource set. The user equipment (UE) determines the reference signal measurement resources of the serving cell based on the QCL RS contained in the currently indicated TCI state, and further determines which resource set associated with the candidate cell is effective, ensuring that the measurement resource types of the candidate cell and the serving cell are the same.

[0231] For example, the network-side equipment indicates two report configurations for each candidate cell, with each report configuration associated with one set of measurement resources. The UE determines the reference signal measurement resources of the serving cell based on the QCL RS contained in the currently indicated TCI state, and further determines which report configuration is effective. The set of measurement resources associated with the effective report configuration is of the same type as the reference signal measurement resources of the serving cell.

[0232] For example, the network-side device indicates one report configuration for each candidate cell. This report configuration is associated with one or more reference signal resource sets, such as an SSB resource set, a CSI-RS resource set, or a resource set containing both SSB and CSI-RS resources. The network-side device can indicate the type of reference signal measurement resources in the report configuration (e.g., including a measurement resource set ID in the report). The UE determines the reference signal resource set of the candidate cell based on the reference signal measurement resource type indicated by the network, and then determines the reference signal measurement resource set of the current serving cell.

[0233] As an optional embodiment, sending the measurement result to the network-side device when a trigger event is met includes:

[0234] A triggering event is determined based on third information, wherein the triggering event is associated with the third information, and the association between the triggering event and the third information is configured by the network-side device.

[0235] If the triggering event is met, the measurement result is sent to the network-side device;

[0236] The third information includes at least one of the following:

[0237] (1) The measurement reporting configuration of the candidate cell, such as LTM CSI report configuration or CSI report configuration; wherein, the triggering events associated with a certain measurement reporting configuration include one or more, and the threshold of each triggering event can be the same or different.

[0238] (2) The measurement resource set associated with the candidate cell, such as an LTM CSI resource set or a CSI resource set; each measurement resource set can be associated with one or more trigger events, and the thresholds of each trigger event can be the same or different. For example, one report configuration is associated with two measurement resource sets, one of which contains CSI-RS resources and the other contains SSB resources. One measurement resource set corresponds to one resource set / resource setting. Another example: one report configuration is associated with one measurement resource set, where the measurement resources are either CSI-RS or SSB.

[0239] (3) Candidate cell; the triggering events associated with each candidate cell can be the same or different. For example, the network-side device indicates the association between candidate cells and triggering events. If the triggering events associated with each candidate cell are different, then the event IDs of the triggering events indicated by the network side will be different, as shown in Table 1 below.

[0240] Table 1: Relationship between candidate cells and triggering events.

[0241] Candidate Cell1 Candidate Cell3 Candidate Cell5 Candidate Cell7 eventID-1 eventID-3 eventID-5 eventID-7

[0242] The event ID can represent LTM Event2, LTM Event3, LTM Event4, and LTM Event5.

[0243] (4) Measurement resources of candidate cells, such as LTM CSI resource and CSI resource. If the network-side equipment configures measurement resources for each candidate cell, it can also refer to associating measurement resources with triggering events. Optionally, CSIResource can be a set of CSI-RS (CSI-RS for beam management) or SSBresource, and CSI Resource is used to indicate the beam measurement resources of candidate cells.

[0244] In this embodiment, the terminal can determine the trigger event for measurement reporting based on the association between the trigger event indicated by the network-side device and the third information.

[0245] Optionally, if the third information is associated with at least two triggering events, the parameter thresholds for each triggering event may be different. For example, a report config may be associated with triggering events LTM4 and LTM5, and the absolute thresholds for beam quality used for comparison in these two triggering events may be different.

[0246] As an optional embodiment, the method further includes: obtaining relevant parameters of the triggering event configured by the network-side device, wherein the relevant parameters include at least one of the following:

[0247] The identifier (event ID) that triggered the event;

[0248] The parameter threshold for triggering the event must be met;

[0249] Hysteresis;

[0250] Trigger Time (TTT).

[0251] In this embodiment, the relevant parameters of the triggering event can be configured separately by the network-side device, or configured together with the third information. For example, the relevant parameters are included in the report config, or configured together with the third information and the triggering event.

[0252] As an optional embodiment, the network-side device may indicate relevant parameters of the triggering event based on resources (per-Resource).

[0253] As an optional embodiment, each of the third pieces of information is associated with at least one triggering event;

[0254] The step of sending the measurement result to the network-side device when the trigger event is met includes:

[0255] If the third information is associated with at least two triggering events, the measurement result is sent to the network-side device if all triggering events are satisfied.

[0256] Alternatively, if the third information is associated with at least two triggering events, the measurement result is sent to the network-side device if any one of the triggering events is satisfied.

[0257] In this embodiment, if the third information is associated with multiple triggering events, the terminal can report the measurement result when all triggering events are met, or it can report the measurement result when any one of the triggering events is met.

[0258] As an optional embodiment, the method further includes: receiving updated reference signal measurement resources and / or updated triggering events sent by the network-side device;

[0259] Beam measurement is performed based on the updated reference signal measurement resources to obtain measurement results; and / or, the measurement results are sent to the network-side device based on the updated trigger event.

[0260] In this embodiment, the reference signal measurement resources of the candidate cell and / or serving cell can be dynamically changed or updated, and the triggering event can also be dynamically changed or updated. Network-side equipment can send updated indication information of the reference signal measurement resources and / or updated triggering events via Medium Access Control (MAC) control element (CE) or Downlink Control Information (DCI). For example, the terminal, based on updated transmission configuration information and / or resource configuration information, redetermines the reference signal measurement resources of the serving cell and the candidate cell, and uses the redetermined reference signal measurement resources to perform beam measurement reporting.

[0261] For example, the terminal may still perform beam measurements according to the determined reference signal measurement resources and report the measurement results when the updated trigger event is met. Alternatively, the terminal may re-determine the reference signal measurement resources of the serving cell and the candidate cells based on the updated transmission configuration information and / or resource configuration information, and report the measurement results when the updated trigger event is met.

[0262] The embodiments of this application provide a method for a terminal to determine the measurement resources of the current serving cell and / or candidate cells based on the TCI state and resource configuration information sent by the network side. For example, the reference signal measurement resources of the serving cell are: the QCL RS (CSI-RS) included in the TCI state indicated by the network-side equipment, or the SSB co-located (QCL-ed) with this QCL RS (such as TRS). The reference signal measurement resources of the candidate cell are: two sets of measurement resources (such as an SSB set and a CSI-RS set) are indicated for the candidate cell, and the effective RS set corresponding to the candidate cell is determined according to the RS type of the current beam of the serving cell. The beam measurement reporting trigger event is associated with Report / Resource setting / Resource set / candidate cell to ensure that the terminal can promptly report the beam measurement results triggered by the event, so as to assist the network-side equipment in timely cell handover, and further reduce the beam handover delay or cell handover delay caused by event-triggered LTM.

[0263] The following example illustrates a method in this application for a terminal to determine the reference signal measurement resources of the serving cell, determine the reference signal measurement resources of a candidate cell, and perform event-triggered beam measurement reporting.

[0264] Example 1: Assume the transmission configuration information is a TCI state; the terminal determines the reference signal measurement resources of the serving cell according to the TCI state, and then determines the reference signal measurement resources of the candidate cell: the network side indicates a report config for each candidate cell, associating two resource sets; the terminal determines which measurement resource set the candidate cell uses based on the reference signal in the TCI state indicated by the network side, and the triggered event is associated with the LTM CSI report config.

[0265] The steps for the terminal to implement the beam measurement reporting include:

[0266] Step 11: The base station indicates to the terminal the candidate cells for measurement, including LTM Candidate-1 to LTM Candidate-8;

[0267] The base station instructs the terminal to report measurements in the following ways: event-triggered LTM measurement reporting; and beam measurement reporting when the base station instructs the terminal to meet the leaving condition. The leaving condition refers to the terminal triggering measurement result reporting when the duration of the measurement result (such as the L1-RSRP value) being below the offset-hysteresis value reaches the trigger time (TimeToTrigger). The measurement resource sets associated with the LTM CSI report config are resource set1 (which is the CSI-RS resource set) and resource set2 (which is the SSB resource set).

[0268] The base station instructs the terminal to report N=4 beams, including the current beam of the serving cell. The base station instructs the SR (Survey Reporting Config) to be used by the terminal to request measurement reporting resources. The trigger time is LTM Event 3. The base station instructs the LTM CSI report configuration to be associated with Event LTM3, which can be understood as the third piece of information being the measurement reporting configuration of the candidate cell.

[0269] For each candidate cell, the measurement resources indicated by the base station are as follows:

[0270] LTM-Candidate1:SSB1;

[0271] LTM-Candidate2:SSB2;

[0272] LTM-Candidate3:SSB3;

[0273] LTM-Candidate4:SSB4;

[0274] LTM-Candidate5:SSB5;

[0275] LTM-Candidate6:SSB6;

[0276] LTM-Candidate7:SSB7;

[0277] LTM-Candidate8:SSB8;

[0278] The time-frequency resources of each SSB included above are indicated to the terminal through LTM candidate cell (LTM-Candidate) configuration or LTMMSSB configuration (LTM-SSB-Config). The base station indicates another resource set for each candidate cell as the CSI-RS resource set, and the indication method is similar to that of the SSB resource set mentioned above, so it will not be elaborated here.

[0279] Step 12: The terminal measures the beam quality of the serving cell, for example, by measuring the SSB of the QCL RS co-location in the TCI state indicated by the base station, and obtains the measurement results. The correspondence between the measurement results and the corresponding Synchronization Signal Block Resource Indicator (SSBRI) is as follows: cell0:SSBRI0:5dB;

[0280] Step 13: The terminal selects the SSB resource set of each candidate cell as the measurement resource according to the base station's instructions, and obtains the measurement results (taking L1-RSRP as an example). The correspondence between the measurement results and the corresponding SSBRI is as follows:

[0281] {

[0282] cell1:SSBRI1 L1-RSRP: 5dB;

[0283] cell2:SSBRI2 L1-RSRP: 7dB;

[0284] cell3:SSBRI3 L1-RSRP: 10dB;

[0285] cell4:SSBRI4 L1-RSRP: 5dB;

[0286] cell5:SSBRI5 L1-RSRP: 11dB;

[0287] cell6:SSBRI6 L1-RSRP: 5dB;

[0288] cell7:SSBRI7 L1-RSRP: 11dB;

[0289] cell8:SSBRI8 L1-RSRP: 6dB

[0290] }

[0291] Step 14: At time T1, the terminal compares the filtered measurement results of the serving cell with the measurement results of the candidate cells. It finds that the beam quality measured by candidate cell 3 (LTM-Candidate 3), candidate cell 5 (LTM-Candidate 5), and candidate cell 7 (LTM-Candidate 7) is at least offset + hysteresis = 4dB higher than the beam quality measured by the current serving cell (5dB). This satisfies the event-triggered measurement reporting conditions Event LTM3 and leaving condition, and the terminal triggers the beam measurement result reporting.

[0292] Event LTM3 means that the beam of the candidate cell becomes the amount of offset better than the beam of the serving cell.

[0293] Step 15: If the terminal does not find an available Physical Uplink Shared Channel (PUSCH) resource to send the measurement results, the terminal sends a Scheduling Request (SR) message to request uplink resources for beam measurement result reporting.

[0294] Step 16: The terminal sends a MAC CE on the uplink resources allocated by the base station. The MAC CE carries the following information: the measurement reporting configuration identifier (LTM-CSI-ReportConfigId) or trigger event identifier used by the terminal, the beam measurement results of candidate cells 3, 5, 7, and 2, and the beam measurement results of the serving cell.

[0295] {

[0296] LTM-CSI-ReportConfigId#1 / Event LTM3,

[0297] SSBRI3 L1-RSRP: 10dB;

[0298] SSBRI5 L1-RSRP: 11dB;

[0299] SSBRI7 L1-RSRP: 11dB;

[0300] SSBRI2 L1-RSRP: 7dB;

[0301] Current beam:

[0302] SSBRI0 L1-RSRP: 5dB

[0303] }

[0304] The terminal reports the measurement results three times consecutively according to the reporting amount (IEReportAmount) configured in the measurement reporting configuration.

[0305] Step 17: At time T2, the terminal compares the measurement results of the serving cell and the candidate cell. Assuming that the beam quality of candidate cell 7 (LTM-Candidate 7) is found to be 2 dB lower than the current serving cell's beam quality (offset-hysteresis = 2 dB), satisfying the leaving condition, the terminal triggers beam measurement reporting. The reported beam measurement results exclude the beam measurement results of LTM-Candidate 7. The reported measurement results include:

[0306] {

[0307] SSBRI3 L1-RSRP: 10dB;

[0308] SSBRI5 L1-RSRP: 11dB;

[0309] SSBRI2 L1-RSRP: 7dB;

[0310] Current beam:

[0311] SSBRI0 L1-RSRP: 5dB

[0312] }

[0313] Step 18: The terminal receives the cell handover signaling (MAC CE) sent by the base station, and performs cell handover according to the target cell (e.g., candidate cell 5) indicated in the cell handover signaling, and switches to cell 5.

[0314] Example 2: Assume the transmission configuration information is a TCI state; the terminal determines the reference signal measurement resources of the serving cell according to the instructions of the TCI state, and then determines the reference signal measurement resources of the candidate cell: the network side instructs two report configs for each candidate cell, and each report config is associated with one resource set. The terminal determines which measurement resource set the candidate cell uses based on the reference signal in the TCI state indicated by the network side, and the triggering event is associated with the LTM CSI report config.

[0315] The steps for the terminal to implement the beam measurement reporting include:

[0316] Step 21: The base station indicates to the terminal the candidate cells for measurement, including LTM Candidate-1 to LTM Candidate-8;

[0317] The base station instructs the terminal to report LTM measurements via event-triggered methods. The base station instructs the terminal to provide two LTM CSI report configurations: LTM-CSI-ReportConfig1 and LTM-CSI-ReportConfig2. Each LTM-CSI-ReportConfig is associated with a measurement resource set or measurement resource configuration (LTM-CSI-ResourceConfig). Event-triggered indication information is contained within the LTM-CSI-ResourceConfig.

[0318] The base station instructs the terminal to report N=4 beams, including the current beam report; the base station instructs a dedicated SR for the terminal to request measurement reporting resources: for each candidate cell, the measurement resource set associated with the LTM-CSI-ReportConfig1 indicated by the base station is as follows, and the measurement resource set can be represented by Non-Zero Power CSI-RS (NZP-CSI-RS).

[0319] LTM-Candidate1:NZP-CSI-RS resource set1;

[0320] LTM-Candidate2:NZP-CSI-RS resource set2;

[0321] LTM-Candidate3:NZP-CSI-RS resource set3;

[0322] LTM-Candidate4:NZP-CSI-RS resource set4;

[0323] LTM-Candidate5:NZP-CSI-RS resource set5;

[0324] LTM-Candidate6:NZP-CSI-RS resource set6;

[0325] LTM-Candidate7:NZP-CSI-RS resource set7;

[0326] LTM-Candidate8:NZP-CSI-RS resource set8;

[0327] The instructions for LTM-CSI-ReportConfig2 are similar to those for LTM-CSI-ReportConfig1, except that the LTM-CSI-ResourceConfig associated with LTM-CSI-ReportConfig2 is an SSB resource set.

[0328] Step 22: The terminal measures the beam quality of the serving cell, for example, by measuring the QCL RS in the TCI state indicated by the base station, and obtains the following measurement results: cell0:CRI0:5dB;

[0329] Step 23: The terminal determines the measurement resource type of the candidate cell as CSI-RS according to the measurement resource type of the serving cell. Following the base station's instructions, the terminal activates and measures the measurement resource set (CSI-RS set) of each candidate cell, obtaining the measurement results corresponding to the CSI-RS Resource Indicator (CRI) (taking L1-RSRP as an example), as follows:

[0330] {

[0331] cell1:CRI1 L1-RSRP: 5dB;

[0332] cell2:CRI2 L1-RSRP: 7dB;

[0333] cell3:CRI3 L1-RSRP: 10dB;

[0334] cell4:CRI4 L1-RSRP: 5dB;

[0335] cell5:CRI5 L1-RSRP: 1dB;

[0336] cell6:CI6 L1-RSRP: 5dB;

[0337] cell7:CRI7 L1-RSRP: 3dB;

[0338] cell8:CRI8 L1-RSRP: 6dB

[0339] }

[0340] Step 24: At time T1, the terminal compares the filtered serving cell measurement results with the candidate cell measurement results. It finds that the beam quality of candidate cell LTM-Candidate 3 is higher than the beam quality of the current serving cell by offset+hysteresis=4dB, which satisfies the event-triggered measurement reporting condition LTM3, or the event-triggered measurement reporting condition LTM2 (the beam quality of the serving cell is lower than the pre-indicated threshold (assuming the threshold is 9dB)). The terminal then triggers the beam measurement result reporting.

[0341] Event LTM2 is: the difference between the beam quality of the serving cell and the absolute threshold.

[0342] Step 25: If the terminal does not find an available PUSCH resource to send the measurement results, the terminal sends an SR request message to request uplink resources for reporting beam measurement results.

[0343] Step 26: The terminal sends a MAC CE on the uplink resources allocated by the base station. The MAC CE carries the following information: the measurement reporting configuration identifier (LTM-CSI-ReportConfigId) or trigger event identifier used by the terminal, the beam measurement results of candidate cell 3, and the beam measurement results of the serving cell.

[0344] {

[0345] LTM-CSI-ReportConfigId#1 / Event LTM3,

[0346] CRI3 L1-RSRP: 10dB;

[0347] Current beam:

[0348] CRI0 L1-RSRP: 5dB

[0349] }

[0350] The terminal reported the measurement results three times consecutively according to the ReportAmount instruction.

[0351] Step 28: The terminal receives the cell handover signaling (MAC CE) sent by the base station, and performs cell handover according to the target cell (e.g., candidate cell 3) indicated in the cell handover signaling, and switches to LTM-candidate cell 3.

[0352] Example 3: Assume the transmission configuration information is a TCI state; the terminal determines the reference signal measurement resources of the serving cell based on the TCI state, and then determines the reference signal measurement resources of the candidate cells: the network side instructs two report configs for each candidate cell, each report config is associated with one resource set. The terminal determines which measurement resource set the candidate cell uses based on the reference signals in the TCI state indicated by the network side. Triggering events are associated with LTM CSI Resource sets, and each LTM CSI Resource set is associated with multiple triggering events, each with a different threshold. The measurement resource is CSI-RS.

[0353] The steps for the terminal to implement the beam measurement reporting include:

[0354] Step 31: The base station indicates to the terminal that the candidate cells for measurement are LTM Candidate-1 to LTM Candidate-8;

[0355] The base station instructs the terminal to report LTM measurements via event-triggered methods. The base station instructs the terminal to use two LTM-CSI report configurations: LTM-CSI-ReportConfig1 and LTM-CSI-ReportConfig2. Each LTM-CSI-ReportConfig is associated with a measurement resource set or measurement resource configuration (LTM-CSI-ResourceConfig). Event-triggered instructions are contained within the LTM-CSI-ResourceConfig.

[0356] The indications related to the triggering event include: threshold, hysteresis, trigger time (TimeToTrigger), and the number of reporting cells (reportQuantityCell). The base station instructs the terminal to report N=4 beams, including current beam reporting; the base station instructs a dedicated SR for the terminal to request measurement reporting resources.

[0357] Step 32: The terminal measures the beam quality of the serving cell (measures the QCLRS in the TCI state indicated by the base station), and obtains the following measurement results: cell0:CRI0: 5dB;

[0358] Step 33: The terminal determines the reference signal measurement resource type of the candidate cell as CSI-RS according to the reference signal measurement resource type of the serving cell. Following the base station's instructions, the terminal measures the measurement resource set (CSI-RS set) of each candidate cell, obtaining the measurement results (taking L1-RSRP as an example) as follows:

[0359] {

[0360] cell1:CRI1 L1-RSRP: 5dB;

[0361] cell2:CRI2 L1-RSRP: 7dB;

[0362] cell3:CRI3 L1-RSRP: 10dB;

[0363] cell4:CRI4 L1-RSRP: 5dB;

[0364] cell5:CRI5 L1-RSRP: 1dB;

[0365] cell6:CI6 L1-RSRP: 5dB;

[0366] cell7:CRI7 L1-RSRP: 3dB;

[0367] cell8:CRI8 L1-RSRP: 6dB

[0368] }

[0369] Step 34: At time T1, the terminal compares the measurement results of the serving cell and the candidate cell. It finds that the beam quality of candidate cell LTM-Candidate 3 is 4 dB higher than the current serving cell's quality (offset + hysteresis = 4 dB), satisfying both event-triggered measurement reporting condition LTM3 and event-triggered measurement reporting condition LTM2 (the serving cell's beam quality is lower than a pre-indicated threshold (assuming the threshold is 9 dB)). The terminal then triggers beam measurement result reporting. In this case, beam measurement result reporting is triggered when both Event LTM2 and Event LTM3 are satisfied. Alternatively, beam measurement result reporting can be triggered when either Event LTM2 or Event LTM3 is satisfied.

[0370] Step 35: If the terminal does not find an available PUSCH resource, it will send an SR request for uplink resources for beam measurement result reporting.

[0371] Step 36: The terminal sends a MAC CE on the uplink resources allocated by the base station. The MAC CE carries the following information: the measurement reporting configuration identifier (LTM-CSI-ReportConfigId) or trigger event identifier used by the terminal, the beam measurement results of candidate cell 3, and the beam measurement results of the serving cell.

[0372] {

[0373] LTM-CSI-ReportConfigId#1 / Event LTM3,

[0374] CRI3 L1-RSRP: 10dB;

[0375] Current beam:

[0376] CRI0 L1-RSRP: 5dB

[0377] }

[0378] The terminal reported the measurement results three times consecutively according to the ReportAmount instruction.

[0379] Step 38: The terminal receives the cell handover signaling (MAC CE) sent by the base station, performs cell handover according to the target cell (candidate cell 3) indicated in the cell handover signaling, and switches to LTM-candidate cell 3.

[0380] Example 4: The terminal determines the reference signal measurement resources of the serving cell based on the reference signal measurement resources of the candidate cell. The triggering event for measurement reporting is associated with the candidate cell, and the base station indicates the associated triggering event identifier and related information in the candidate cell configuration.

[0381] The steps for the terminal to implement the beam measurement reporting include:

[0382] Step 41: The base station indicates to the terminal that the candidate cells for measurement are LTM Candidate-1 to LTM Candidate-8;

[0383] The base station instructs the terminal to report in the following ways: event-triggered LTM measurement reporting, the base station instructs the terminal to report N=4 beams, including current beam reporting; the base station instructs a dedicated SR for the terminal to request measurement reporting resources.

[0384] The base station indicates the relevant parameters of the triggering event based on the candidate cell (per candidate). For example, for candidate cell1, it indicates the triggering event LTM-Event3; for candidate cell3, it indicates the triggering condition LTMEvent3.

[0385] Step 42: The terminal, following the base station's instructions, measures the measurement resources of each candidate cell indicated in the LTM channel measurement resource indication (ltm-ResourcesForChannelMeasurement-r18), and obtains the measurement results (taking L1-RSRP as an example) as follows:

[0386] {

[0387] cell1:SSBRI1 L1-RSRP: 5dB;

[0388] cell2:SSBRI2 L1-RSRP: 7dB;

[0389] cell3:SSBRI3 L1-RSRP: 10dB;

[0390] cell4:SSBRI4 L1-RSRP: 5dB;

[0391] cell5:SSBRI5 L1-RSRP: 4dB;

[0392] cell6:SSBRI6 L1-RSRP: 5dB;

[0393] cell7:SSBRI7 L1-RSRP: 3dB;

[0394] cell8:SSBRI8 L1-RSRP: 6dB

[0395] }

[0396] Step 43: The terminal measures the beam quality of the serving cell (measures the SSB of the QCLRS co-located site in the TCI state indicated by the base station), and obtains the following measurement results: cell0:SSBRI0->5dB;

[0397] Step 44: At time T1, the terminal compares the measurement results of the serving cell and the candidate cell. It finds that the beam quality of candidate cell LTM-Candidate 3 is 4 dB higher than the current serving cell's quality (offset + hysteresis), satisfying the event-triggered measurement reporting condition Event LTM 3. The terminal then triggers beam measurement result reporting. Furthermore, the terminal finds that the beam quality of candidate cell LTM-Candidate 2 is higher than the threshold (Threshold_candidate cell) for the candidate cell, while the beam quality of the serving cell is lower than the threshold (Threhsold_serving cell) for the serving cell, satisfying the event-triggered measurement reporting condition Event LTM 5. The terminal then triggers beam measurement reporting. In this case, the terminal reports the measurement results only when both Event LTM 3 and Event LTM 5 are satisfied.

[0398] Event LTM 5: The beam quality of the serving cell is worse than absolute threshold 1, and the beam quality of the candidate cell is better than absolute threshold 2.

[0399] Step 45: If the terminal does not find an available PUSCH resource, it will send an SR request for uplink resources for beam measurement result reporting.

[0400] Step 46: The terminal sends a MAC CE on the uplink resources allocated by the base station. The MAC CE carries the following information: the measurement reporting configuration identifier (LTM-CSI-ReportConfigId) or trigger event identifier used by the terminal, the beam measurement results of candidate cell 2 and candidate cell 3, and the beam measurement results of the serving cell.

[0401] {

[0402] LTM-CSI-ReportConfigId#1 / Event LTM3,

[0403] SSBRI2 L1-RSRP: 7dB;

[0404] SSBRI3 L1-RSRP: 10dB;

[0405] Current beam:

[0406] SSBRI0 L1-RSRP: 5dB

[0407] }

[0408] The terminal reports the measurement results three times consecutively as instructed by IE ReportAmount.

[0409] Step 48: The terminal receives the cell handover signaling (MAC CE) sent by the base station, performs cell handover according to the target cell (candidate cell 3) indicated in the cell handover signaling, and switches to cell 3.

[0410] Example 5: In a single cell, the triggering event is indicated in the measurement report configuration / resource set configuration / measurement resource, which determines the measurement resources of the current beam based on the measurement resource set of the new beam.

[0411] The steps for the terminal to implement the beam measurement reporting include:

[0412] Step 51: In the beam measurement reporting triggered by the event indicated by the base station to the terminal, the triggering event is associated with CSI-ReportConfig; the base station indicates the measurement resources of the new beam to the terminal through the configuration of the CSI resource set.

[0413] The base station indicates in CSI-ReportConfig that the trigger event for measurement reporting is Event-2 / 1 / 7 (the base station can also indicate the event ID in CSI-ResourceConfig), instructing the terminal to report the measurement when the measurement result meets Event-2 / 1 / 7.

[0414] Event-2 is defined as follows: the quality of at least one new beam (such as L1-RSRP) is a threshold value better than the quality of the current beam.

[0415] Event-1 is: The quality of the current beam is worse than a certain threshold.

[0416] Event-7 is: the quality of at least one new beam (such as L1-RSRP) is higher than the beam quality of the M best quality RSs in the activated TCI state information by a threshold value. M is an RRC parameter configured with subjective UE capability signaling.

[0417] The base station instructs the terminal to report N=4 beams, including the current beam. The New beam measurement resource is indicated as CSI-RS resource set 1, which contains the resources {CSI-RS1, CSI-RS2, CSI-RS3, CSI-RS4}.

[0418] Step 52: The base station indicates 64 TCI states to the terminal via RRC, and activates 8 of them using MAC CE. At time n, the base station indicates TCI state 1. The type-D source reference signal (source RS) in TCI state 1 is CSI-RS5. CSI-RS2 belongs to a CSI-RS resource set indicating repetition.

[0419] Step 53: The terminal determines that the type of reference signal measurement resource of the new beam indicated by the base station is CSI-RS. Based on the type of reference signal measurement resource of the new beam, the terminal determines that the reference signal measurement resource of the current beam is type-D source RS: CSI-RS5 in TCIstate1.

[0420] The terminal measures the L1-RSRP of CSI-RS5 and obtains L1-RSRP5 = 3dB. At the same time, the terminal measures CSI-RS resource set 1 in the newbeam measurement resources and obtains L1-RSRP1 = 7dB, L1-RSRP2 = 8dB, L1-RSRP3 = 4dB, and L1-RSRP4 = 5dB.

[0421] Step 54: The terminal compares the quality of the new beam with that of the current beam. It finds that the beam quality of CSI-RS1 for the new beam is 4 dB higher than L1-RSRP5 for the current beam, and the beam quality of CSI-RS2 is 5 dB higher than L1-RSRP5 for the current beam, satisfying the triggering conditions of Event-2 / Event-1 / Event-7. The terminal then triggers the beam measurement reporting for the event.

[0422] Step 55: The terminal sends an SR request message to request uplink resources. The terminal reports the event-triggered beam measurement results on the uplink PUSCH resources scheduled by the base station through DCI format 0_2: CRI1+L1-RSRP1, CRI2+L1-RSRP2, CRI3+L1-RSRP3, CRI4+L1-RSRP4. The terminal uses differential reporting with a quantization bit count of 4 bits and a step size of 2dB.

[0423] Step 56: The base station receives the measurement report result from the terminal and updates the indicated TCI state at the next moment, changing the type D source RS in the TCI state to CSI-RS1.

[0424] Example 6: In a single cell, the triggering event is indicated in the report config / resource set configuration / resource. The base station determines the measurement resources for the new beam based on the reference signal in the TCI state indicated by the base station.

[0425] The steps for the terminal to implement the beam measurement reporting include:

[0426] Step 61: In the beam measurement reporting triggered by the event indicated by the base station to the terminal, the triggering event is associated with CSI-ReportConfig; the base station indicates the measurement resources of the new beam to the terminal through the configuration of CSI-resource set.

[0427] The base station indicates in CSI-ReportConfig that the event ID that triggers the measurement reporting is Event-2 (the base station can also indicate the event ID in CSI-ResourceConfig), instructing the terminal to report the measurement when the measurement result meets Event-2.

[0428] The base station instructs the terminal to report N=4 beams, including the current beam. The indicator for the new beam measurement resources is CSI-RS resource set 1, which contains the resources: {CSI-RS1, CSI-RS2, CSI-RS3, CSI-RS4}.

[0429] Step 62: The base station indicates 64 TCI states to the terminal via RRC, and activates 8 of them using MAC CE. At time n, the base station indicates TCI state 1. The type-D source RS in TCI state 1 is CSI-RS5. CSI-RS2 belongs to a CSI-RS resource set indicating repetition.

[0430] Step 63: The terminal measures the L1-RSRP of CSI-RS5 and obtains L1-RSRP5 = 3dB. At the same time, the terminal measures CSI-RS resource set 1 in the new beam measurement resources and obtains L1-RSRP1 = 7dB, L1-RSRP2 = 8dB, L1-RSRP3 = 4dB, and L1-RSRP4 = 5dB.

[0431] Step 64: The terminal compares the quality of the new beam with the current beam and finds that the beam quality of CSI-RS1 is 4dB higher than the L1-RSRP5 of the current beam, and the beam quality of CSI-RS2 is 5dB higher than the L1-RSRP5 of the current beam, thus satisfying the triggering condition of Event-2. The terminal triggers the beam measurement reporting triggered by the event.

[0432] Step 65: The terminal sends an SR request message to request uplink resources. The terminal reports the event-triggered beam measurement results on the uplink PUSCH resources scheduled by the base station through DCI format 0_2: CRI1+L1-RSRP1, CRI2+L1-RSRP2, CRI3+L1-RSRP3, CRI4+L1-RSRP4. The terminal uses differential reporting with a quantization bit count of 4 bits and a step size of 2dB.

[0433] Step 66: The base station receives the measurement report result from the terminal and updates the indicated TCI state at the next moment, changing the type D source RS in the TCI state to CSI-RS1.

[0434] In this embodiment, the reference signal measurement resources of the serving cell can be: the QCL RS (CSI-RS) included in the currently indicated TCI state, or the SSB QCL-ed with this QCL RS (e.g., TRS). The reference signal measurement resources of the candidate cell can be: indicating two sets of measurement RS (SSB and CSI-RS) for the candidate cell, and determining which RS set of the candidate cell is effective based on the RS type of the current beam of the serving cell. The triggering event of beam measurement reporting is associated with Report / Resource setting / Resource set / candidate cell to ensure that the base station can promptly feedback the beam measurement results triggered by the event to assist the base station in timely cell handover, further reducing the beam handover delay / cell handover delay caused by event-triggered LTM.

[0435] In embodiments of this application, the terminal can determine the reference signal measurement resources of the serving cell based on the transmission configuration information sent by the network-side device, and determine the reference signal measurement resources of the candidate cell based on the reference signal measurement resources of the serving cell; or, it can determine the reference signal measurement resources of the candidate cell based on the resource configuration information sent by the network-side device, and determine the reference signal measurement resources of the serving cell based on the reference signal measurement resources of the candidate cell and the transmission configuration information sent by the network-side device, thereby ensuring that the reference signal measurement resource types of the serving cell and the candidate cell are the same, and thus ensuring the accuracy of the measurement results reported by the terminal.

[0436] like Figure 2 As shown in the embodiments of this application, a beam measurement reporting method is also provided, applied to network-side equipment, including:

[0437] Step 201: The network-side device sends transmission configuration information and / or resource configuration information to the terminal; the transmission configuration information is used to indicate the reference signal measurement resources of the terminal's serving cell; the resource configuration information is used to configure the reference signal measurement resources of the terminal's candidate cells;

[0438] Step 202: The network-side device receives the measurement results sent by the terminal. The measurement results are obtained by beam measurement based on the reference signal measurement resources of the serving cell and / or the reference signal measurement resources of the candidate cell.

[0439] In this embodiment, the network-side device can send transmission configuration information to the terminal, which includes relevant parameters for the terminal's transmission information. The terminal can determine the reference signal measurement resources of the serving cell based on this transmission configuration information.

[0440] When the reference signal measurement resources of the serving cell can be determined, the terminal can determine the reference signal measurement resources of the candidate cell based on the reference signal measurement resources of the serving cell. This ensures that the reference signal measurement resources of the serving cell and the candidate cell are of the same type.

[0441] Network-side equipment can send resource configuration information to the terminal. This resource configuration information can configure the type of reference signal measurement resources for candidate cells. The terminal can determine the reference signal measurement resources of the candidate cells based on the resource configuration information. To ensure that the reference signal measurement resources of the serving cell are of the same type as those of the candidate cells, the terminal can determine the measurement resources of the serving cell based on the reference signal measurement resources of the candidate cells and the transmission configuration information sent by the network-side equipment.

[0442] After determining the reference signal measurement resources of the serving cell, the terminal measures the reference signal measurement resources of the serving cell and obtains the measurement results; and / or, after determining the reference signal measurement resources of a candidate cell, the terminal measures the reference signal measurement resources of the candidate cell and obtains the measurement results. Upon meeting a triggering event, the terminal reports the measurement results to the network-side device.

[0443] In embodiments of this application, the network-side device sends transmission configuration information and / or resource configuration information to the terminal. The transmission configuration information is used to determine the reference signal measurement resources of the serving cell. The terminal can determine the reference signal measurement resources of the candidate cell based on the reference signal measurement resources of the serving cell. The resource configuration information is used to determine the reference signal measurement resources of the candidate cell. The terminal can determine the reference signal measurement resources of the serving cell based on the reference signal measurement resources of the candidate cell and the transmission configuration information, thereby ensuring that the reference signal measurement resource types of the serving cell and the candidate cell are the same, and thus ensuring the accuracy of the measurement results reported by the terminal.

[0444] As an optional embodiment, the transmission configuration information includes TCI status information; the QCL RS included in the TCI status information is used to determine the reference signal measurement resources of the serving cell of the terminal.

[0445] In this embodiment, the transmission configuration information sent by the network-side device includes TCI state information. This can be understood as the transmission configuration information including TCI state information, and may also include other transmission-related information; or it can be understood as the transmission configuration information being the TCI state information. The TCI state information includes QCL RS, and the reference signal measurement resource of the serving cell can be a QCL RS or an SSB quasi-co-located with the QCL RS.

[0446] As an optional embodiment, the reference signal measurement resource of the serving cell is: the QCL RS contained in the TCI state information;

[0447] Alternatively, the reference signal measurement resource of the serving cell is a synchronization signal block (SSB) that has a co-location relationship with the QCL RS contained in the TCI status information.

[0448] In this embodiment, the QCL RS includes at least one of the following: a CSI-RS for beam management, a CSI-RS for mobility management, or a TRS. For example, the TCI state can be a CSI-RS, which is a TRS or a CSI-RS for mobility management, or a CSI-RS for beam management. The reference signal measurement resource of the serving cell can be a QCL RS (such as a CSI-RS or a TRS) included in the TCI state, or the reference signal measurement resource of the serving cell is an SSB quasi-co-located with the QCL RS included in the TCI state, such as an SSB quasi-co-located with the TRS.

[0449] As an optional embodiment, sending transmission configuration information to the terminal includes:

[0450] Send at least two TCI status information to the terminal, wherein the QCL RS included in the target TCI status information of the at least two TCI status information is used to determine the reference signal measurement resources of the serving cell;

[0451] The target TCI status information is either predefined TCI status information or determined based on the RSRP of the QCL RS.

[0452] In this embodiment, the network-side device may indicate two TCI state information to the terminal, such as in an mTRP scenario. In this case, the terminal can determine the reference signal measurement resources of the serving cell based on the QCL RS contained in a fixed TCI state information. For example, the measurement resources of the serving cell can be determined based on the QCL RS contained in TCI state 0 or TCI state 1. Alternatively, the terminal can also determine the TCI state to use based on the RSRP values ​​of the QCL RS in multiple TCI states indicated by the network side. For example, the RS corresponding to the minimum value among the L1-RSRP values ​​obtained from measuring the QCL RS can be used as the measurement resources of the serving cell, or the RS corresponding to the maximum value among the L1-RSRP values ​​obtained from measuring the QCL RS can be used as the measurement resources of the serving cell.

[0453] As an optional embodiment, the resource configuration information is used to configure the type of reference signal measurement resources for the candidate cells of the terminal; the reference signal measurement resources of the candidate cells are: a set of measurement resources of the same type as configured in the resource configuration information from at least one set of measurement resources associated with the candidate cells.

[0454] In this embodiment, the network-side device configures resource configuration information for the terminal, and the terminal determines the type of reference signal measurement resources for the candidate cell based on the resource configuration information. The network-side device can configure multiple associated measurement resource sets for the candidate cell, such as an SSB set (setting) composed of SSBs and a CSI-RS setting composed of CSI-RSs. The network-side device can indicate through the resource configuration information that the type of reference signal measurement resources for the candidate cell is an SSB, thus allowing the terminal to determine that the reference signal measurement resources for the candidate cell are an SSB set.

[0455] The terminal can select a reference signal measurement resource of the same type as the reference signal measurement resource of the candidate cell from the transmission configuration as the reference signal measurement resource of the serving cell. For example, if the transmission configuration information is a TCI state, and the QCL RS in the TCI state is a CSI-RS or a TRS, and the reference signal measurement resource of the candidate cell is a CSI-RS, then the terminal determines that the reference signal measurement resource of the serving cell is a CSI-RS.

[0456] As an optional embodiment, the method further includes: sending the measurement reporting configuration of the candidate cell to the terminal via RRC;

[0457] Each candidate cell corresponds to a measurement reporting configuration, and each measurement reporting configuration is associated with at least two measurement resource sets;

[0458] Alternatively, each candidate cell may correspond to two measurement reporting configurations, and each measurement reporting configuration may be associated with a set of measurement resources.

[0459] Alternatively, each candidate cell may correspond to a measurement reporting configuration, and each measurement reporting configuration may be associated with at least one set of measurement resources.

[0460] In this embodiment, the network-side device can configure a measurement reporting configuration for candidate cells, send the measurement reporting configuration to the terminal via RRC, and configure the measurement resource set associated with the measurement reporting configuration. Each candidate cell can correspond to one or more measurement reporting configurations, and the measurement reporting configuration can be associated with one or more measurement resource sets.

[0461] For example, the network-side equipment indicates one measurement reporting configuration for each candidate cell. Each report configuration is associated with two or more reference signal measurement resource sets, such as the SSB resource set and the CSI-RS resource set. The UE determines the reference signal measurement resources of the serving cell based on the QCL RS contained in the currently indicated TCI state, and further determines which resource set associated with the candidate cell is effective, ensuring that the measurement resource types of the candidate cell and the serving cell are the same.

[0462] For example, the network-side equipment indicates two report configurations for each candidate cell, with each report configuration associated with one set of measurement resources. The UE determines the reference signal measurement resources of the serving cell based on the QCL RS contained in the currently indicated TCI state, and further determines which report configuration is effective. The set of measurement resources associated with the effective report configuration is of the same type as the reference signal measurement resources of the serving cell.

[0463] For example, the network-side device indicates one report configuration for each candidate cell. This report configuration is associated with one or more reference signal resource sets, such as an SSB resource set, a CSI-RS resource set, or a resource set containing both SSB and CSI-RS resources. The network-side device can indicate the type of reference signal measurement resources in the report configuration (e.g., including a measurement resource set ID in the report). The UE determines the reference signal resource set of the candidate cell based on the reference signal measurement resource type indicated by the network, and then determines the reference signal measurement resource set of the current serving cell.

[0464] As an optional embodiment, the method further includes: sending to the terminal the association between the measurement reporting trigger event and third information; wherein the third information includes at least one of the following:

[0465] Measurement reporting configuration for candidate cells; such as LTM CSI report config or CSI report config; wherein, the triggering events associated with a measurement reporting configuration include one or more, and the thresholds of each triggering event can be the same or different.

[0466] The measurement resource set associated with the candidate cell; for example, LTM CSI resource set or CSI resourceset; where each measurement resource set can be associated with one or more trigger events, and the thresholds of each trigger event can be the same or different.

[0467] Candidate cells; the triggering events associated with each candidate cell can be the same or different. For example, the network-side device indicates the association between candidate cells and triggering events. If the triggering events associated with each candidate cell are different, then the event IDs of the triggering events indicated by the network side will be different.

[0468] Measurement resources for candidate cells, such as LTM CSI resource or CSI resource. If network-side equipment configures measurement resources for each candidate cell, it can also refer to associating measurement resources with triggering events. Optionally, CSI resource can be a set of CSI-RS (CSI-RS for beam management) or an SSB resource; CSIResource is used to indicate the beam measurement resources of candidate cells.

[0469] As an optional embodiment, the method further includes: sending relevant parameters of the triggering event to the terminal, wherein the relevant parameters include at least one of the following:

[0470] The identifier that triggered the event;

[0471] The parameter thresholds that trigger the event must be met;

[0472] Lag;

[0473] Trigger time.

[0474] In this embodiment, the relevant parameters of the triggering event can be configured separately by the network-side device, or configured together with the third information. For example, the relevant parameters can be included in the report configuration, or configured together with the association between the third information and the triggering event. The network-side device can indicate the relevant parameters of the triggering event based on resources.

[0475] As an optional embodiment, if the third information is associated with at least two triggering events, the parameter thresholds for each triggering event are different.

[0476] As an optional embodiment, the method further includes: sending updated reference signal measurement resources and / or updated trigger events to the terminal when the reference signal measurement resources and / or trigger events are updated.

[0477] In this embodiment, the reference signal measurement resources of the candidate cell and / or serving cell can be dynamically changed or updated, and the triggering event can also be dynamically changed or updated. Network-side devices can send updated indication information of the reference signal measurement resources and / or updated triggering events via MAC-CE or DCI. For example, the terminal, based on updated transmission configuration information and / or resource configuration information, redetermines the reference signal measurement resources of the serving cell and the candidate cell, and uses the redetermined reference signal measurement resources to perform beam measurement reporting.

[0478] For example, the terminal may still perform beam measurements according to the determined reference signal measurement resources and report the measurement results when the updated trigger event is met. Alternatively, the terminal may re-determine the reference signal measurement resources of the serving cell and the candidate cells based on the updated transmission configuration information and / or resource configuration information, and report the measurement results when the updated trigger event is met.

[0479] In embodiments of this application, the network-side device sends transmission configuration information and / or resource configuration information to the terminal. The transmission configuration information is used to determine the reference signal measurement resources of the serving cell. The terminal can determine the reference signal measurement resources of the candidate cell based on the reference signal measurement resources of the serving cell. The resource configuration information is used to determine the reference signal measurement resources of the candidate cell. The terminal can determine the reference signal measurement resources of the serving cell based on the reference signal measurement resources of the candidate cell and the transmission configuration information, thereby ensuring that the reference signal measurement resource types of the serving cell and the candidate cell are the same, and thus ensuring the accuracy of the measurement results reported by the terminal.

[0480] The above embodiments describe the beam measurement reporting method of this application. The following embodiments will further describe the corresponding device in conjunction with the accompanying drawings.

[0481] Specifically, such as Figure 3 As shown, this application embodiment provides a beam measurement reporting device 300, applied to a terminal, including:

[0482] The first determining unit 310 is used to determine reference signal measurement resources, wherein the reference signal measurement resources include at least one of the following: reference signal measurement resources of the serving cell and reference signal measurement resources of the candidate cell;

[0483] The first acquisition unit 320 is used to perform beam measurement based on the reference signal measurement resources and obtain measurement results.

[0484] The first sending unit 330 is used to send the measurement result to the network-side device when a trigger event is met;

[0485] The reference signal measurement resources of the serving cell are determined based on the transmission configuration information sent by the network-side equipment, and the reference signal measurement resources of the candidate cell are determined based on the reference signal measurement resources of the serving cell.

[0486] Alternatively, the reference signal measurement resources of the candidate cell are determined based on the resource configuration information sent by the network-side equipment, and the reference signal measurement resources of the serving cell are determined based on the reference signal measurement resources of the candidate cell and the transmission configuration information sent by the network-side equipment.

[0487] Optionally, the transmission configuration information includes Transmission Configuration Indicator (TCI) status information, and the first determining unit is specifically used to: determine the reference signal measurement resources of the serving cell based on the quasi-co-located QCL reference signal RS contained in the TCI status information.

[0488] Optionally, the first determining unit is specifically used to: determine from the transmission configuration information sent by the network-side device that the measurement resource with the same reference signal measurement resource type as the candidate cell is the reference signal measurement resource of the serving cell.

[0489] Optionally, the first determining unit is specifically used for:
