[0078] In some embodiments, the acquisition of data, information, etc., may comply with the laws and regulations of the country where the location is situated.

[0079] In some embodiments, data, information, etc., may be obtained with the user's consent.

[0080] Furthermore, each element, each row, or each column in the table of this disclosure can be implemented as an independent embodiment, and any combination of any element, any row, or any column can also be implemented as an independent embodiment.

[0081] For beam-based transmission and reception, the current consideration is to configure base stations with periodic, semi-persistent, or non-periodic beam measurement reports.

[0082] However, changes in beam quality are actually the most timely information that terminals can detect. The reporting period length configured by the base station, or the timing of non-periodic reporting, may not be optimal. If the period length is too short, the optimal K beams reported in two separate reports might be the same, indicating minimal change and wasted signaling. Conversely, if the period length is too short, beam changes might occur before the reporting time, impacting communication quality. Similarly, with non-periodic reporting, the base station might trigger terminal reporting too early or too late, which is not the most suitable timing.

[0083] In some embodiments, a UE-initiated, event-triggered beam measurement report is introduced. For example, several triggering events are defined, and when an event is met, the terminal sends a beam report. These events include the following:

[0084] Event 1: The current beam is below the first threshold.

[0085] Event 2: The new beam is of better quality than the current beam (second threshold).

[0086] In some embodiments, high-frequency bands and massive MIMO (Massively Multi-Analog Antennas) are introduced to provide higher spectral efficiency. Massive MIMO can provide greater beamforming gain, effectively compensating for transmission losses caused by high-frequency bands. For a UE in the far field, the electromagnetic waves arriving at the UE from different antenna ports or elements are plane waves, and the optimal transmit beam for the UE is approximately the same. If the UE is in the near field, the electromagnetic waves received by the UE are spherical waves, and the beam for the UE is a three-dimensional (3D) beam surrounding the target UE. Therefore, the optimal transmit beam for the same UE is different for different antenna ports on the base station side.

[0087] Taking near-field beam reporting as an example, how to determine the event that triggers beam reporting is a problem that needs to be solved.

[0088] Therefore, this disclosure provides a communication method in which a terminal receives first information, which can indicate a trigger event. The trigger event is used to trigger a report, and the triggered report includes at least one of second information, third information, and a first measurement value. The second information is an identifier of a reference signal resource, and the third information is an identifier of the port association of the reference signal resource. In other words, through the embodiments of this disclosure, trigger events can be configured for different antenna ports corresponding to different optimal beams, thereby improving the accuracy of beam reporting and increasing communication efficiency.

[0100] Figure 2 is a schematic diagram of a communication method interaction according to an embodiment of the present disclosure. As shown in Figure 2, this embodiment of the present disclosure relates to a communication method for a communication system 100, the method including:

[0101] In step S2101, network device 102 sends first information to terminal 101.

[0102] In some embodiments, terminal 101 receives first information sent by network device 102.

[0103] In some embodiments, the first information is used to indicate a triggering event, which triggers a report. The report includes at least one of the following: second information; third information; and a first measurement value. For example, the terminal can measure a reference signal to obtain a second measurement value. If the second measurement value satisfies the triggering event indicated by the first information, a report is sent to the network device. The reference signal can be a reference signal on a reference signal resource. For example, for a single-port reference signal resource, the reference signal can be a reference signal received by the terminal on a reference signal resource on one port. As another example, for a multi-port reference signal resource, the reference signal can be a reference signal received by the terminal on the same reference signal resource on multiple ports.

[0104] Optionally, the report may include second information. The second information is information about the reference signal resource. Different reference signal resources correspond to different second information. For example, the second information may be an identifier of the reference signal resource. For instance, the reference signal resource corresponding to the current beam and the reference signal resource corresponding to the candidate beam are different. If the current beam satisfies the trigger event, then the second information is the identifier of the reference signal resource corresponding to the current beam. If the candidate beam satisfies the trigger event, then the second information is the identifier of the reference signal resource corresponding to the candidate beam. The current beam satisfying the event can be understood as the measured value of the reference signal on the reference signal resource corresponding to the current beam (i.e., the second measured value corresponding to the current beam) satisfying the trigger event. The candidate beam satisfying the event can be understood as the measured value of the reference signal on the reference signal resource corresponding to the candidate beam (i.e., the second measured value corresponding to the candidate beam) satisfying the trigger event.

[0105] For ease of description, the reference signal resource corresponding to the current beam will be referred to as the first reference signal resource, and the reference signal resource corresponding to the candidate beam will be referred to as the second reference signal resource. If there is a reference signal resource that is not limited to the first or the second, it can be used as the reference signal resource of the current beam, the reference signal resource of the candidate beam, or a reference signal resource that is not associated with any beam.

[0106] For example, assume that reference signal resource #1 is a first reference signal resource, and that reference signal resource #1 is a multi-port reference signal resource, with ports #1-1 and #1-2 corresponding to reference signal resource #1, and reference signal resource #2 is a second reference signal resource. If the measured value of the reference signal received at port #1-1 of reference signal resource #1 satisfies a trigger event, the report may include second information, which may be #1, corresponding to reference signal resource #1. If the measured value of the reference signal on reference signal resource #2 satisfies a trigger event, the report may include second information, which may be #2, corresponding to reference signal resource #2.

[0107] Optionally, the report may include third information. This third information is port information. For example, the reference signal resource may be a multi-port reference signal resource. Different ports may correspond to different current beams. If a current beam satisfies a trigger event, the third information corresponding to the port of that current beam can be reported. Similarly, different ports may correspond to different candidate beams. If a candidate beam satisfies a trigger event, the third information corresponding to the port of that candidate beam can be reported. Furthermore, different ports may correspond to different beam types; for example, some ports may correspond to the current beam, and some to candidate beams. That is, the port corresponding to the current beam and the port corresponding to the candidate beam can be different. If the current beam satisfies a trigger event, the third information corresponding to the port of the current beam can be reported; if a candidate beam satisfies an event, the third information corresponding to the port of the candidate beam can be reported.

[0108] Optionally, the current beam and the candidate beam may correspond to the same reference signal resources, but different ports. That is, the current beam and the candidate beam may correspond to the same second information, but different third information.

[0109] Optionally, the reference signal resources corresponding to the current beam and the candidate beam are different, but the ports are the same. That is, the current beam and the candidate beam can correspond to different second information, but to the same third information.

[0110] Optionally, the current beam and the candidate beam correspond to different reference signal resources and different ports. That is, the current beam and the candidate beam can correspond to different second information and different third information. Optionally, if the current beam and the candidate beam correspond to different reference signal resources, that is, the corresponding second information is different, when the report includes the second information, the network device can determine whether the report was triggered by the current beam or the candidate beam.

[0111] Optionally, if the current beam and the candidate beam correspond to different ports of the same reference signal resource, that is, the corresponding second information is the same but the corresponding third information is different, when the report includes the third information, the network device can determine whether the report is triggered by the current beam or the candidate beam.

[0112] Optionally, if the current beam and the candidate beam correspond to different reference signal resources, and the reference signal resources are multi-port reference signal resources, when the report includes second information and third information, the network device can determine whether the report is triggered by the current beam or the candidate beam based on the second information and the third information. Based on the third information, it can determine which port's current beam or which port's candidate beam is triggered by the report.

[0113] For example, assume that reference signal resource #1 is a first reference signal resource, and that reference signal resource #1 is a multi-port reference signal resource, with ports #1-1 and #1-2 corresponding to reference signal resource #1, and reference signal resource #2 is a second reference signal resource. If the measured value of the reference signal received at port #1-1 of reference signal resource #1 satisfies a trigger event, the report may include third information, which may be #1-1, corresponding to port #1-1 of reference signal resource #1. If the measured value of the reference signal received at port #1-2 of reference signal resource #1 satisfies a trigger event, the report may include third information, which may be #1-2, corresponding to port #1-2 of reference signal resource #1.

[0114] For example, assume that reference signal resource #2 is a second reference signal resource, and that reference signal resource #2 is a multi-port reference signal resource, with ports including port #2-1 and port #2-2. If the measured value of the reference signal received at port #2-1 of reference signal resource #2 satisfies a trigger event, the report may include third information, which can be #2-1, corresponding to port #2-1 of reference signal resource #2. If the measured value of the reference signal received at port #2-2 of reference signal resource #2 satisfies a trigger event, the report may include third information, which can be #2-2, corresponding to port #2-2 of reference signal resource #2.

[0115] For example, assume that reference signal resource #1 is both a first reference signal resource and a second reference signal resource. The ports corresponding to reference signal resource #1 include port #1-1 and port #1-2. Port #1-1 corresponds to the current beam, and port #1-2 corresponds to a candidate beam. That is, the current beam and the candidate beam correspond to different ports of the same reference signal resource. If the measured value of the reference signal received at port #1-1 satisfies a trigger event, then the current beam satisfies the trigger event, and the report can include third information, which can be #1-1. If the measured value of the reference signal received at port #1-2 satisfies the trigger event, then the candidate beam satisfies the trigger event, and the report can include third information, which is #1-2.

[0116] For example, assume that reference signal resource #1 is a first reference signal resource, reference signal resource #2 is a second reference signal resource, and the ports corresponding to reference signal resource #1 include port #1 and port #2, while the ports corresponding to reference signal resource #2 include port #2 and port #3. That is, the first and second reference signal resources may correspond to the same port. If the measured value of the reference signal received at port #1 satisfies the trigger event, then the current beam satisfies the trigger event, and the report may include third information, which is #1. If the measured value of the reference signal received at port #3 satisfies the trigger event, then the candidate beam satisfies the trigger event, and the report may include third information, which is #3. If the measured value of the reference signal received at port #2 satisfies the trigger event, it may be either the current beam or a candidate beam that satisfies the trigger event. The terminal can determine whether the current beam or a candidate beam satisfies the trigger event and report the second and third information. For example, if the current beam satisfies the trigger event, then the second information #1 and the third information #2 are reported. If the candidate beam meets the trigger event, then report the second information #2 and the third information #2.

[0117] Optionally, the report may include a first measurement value. For ease of description, this disclosure refers to the measurement value obtained by the terminal for evaluating whether the trigger event is met as the second measurement value, and the measurement value reported to the network device as the first measurement value.

[0118] In some embodiments, the first measurement and / or the second measurement includes at least one of the following: Layer 1 reference signal received power (L1-RSRP); Layer 1 signal to interference plus noise ratio (L1-SINR); Layer 3 reference signal received power (L3-RSRP); Layer 3 signal to interference plus noise ratio (L3-SINR); Layer 3 Reference Signal Received Quality (L3-RSRQ); Channel State Information (CSI); Channel Quality Indicator (CQI); Precoding Matrix Indicator (PMI); RANK Indicator (RI), but is not limited thereto.

[0119] In some embodiments, the first measurement value and the second measurement value may be the same or different. For example, the second measurement value is a measurement value that satisfies a trigger event, and the first measurement value is a measurement value reported by the terminal to the network device. The terminal may report the measurement value that satisfies the trigger event to the network device, in which case the first measurement value and the second measurement value are the same. The terminal may report the measurement value that satisfies the trigger event together with other measurement values ​​to the network device, or it may only report other measurement values.

[0120] For example, if the measurement value of the current beam satisfies a trigger event, the terminal can report only the measurement value of the current beam. In this case, both the first and second measurements include only the measurement value of the current beam, and the first and second measurements are identical. Alternatively, the terminal can report both the measurement values ​​of the current beam and candidate beams. In this case, the first measurement value includes both the measurement values ​​of the current beam and candidate beams, while the second measurement value includes only the measurement value of the current beam. The first and second measurements are different. Finally, the terminal can also report only the measurement values ​​of candidate beams. In this case, the first measurement value includes the measurement values ​​of candidate beams, while the second measurement value includes the measurement value of the current beam. The first and second measurements are different.

[0121] For example, if the measurement value of a candidate beam satisfies a trigger event, the terminal can report only the measurement value of the candidate beam. In this case, both the first and second measurements include only the measurement value of the candidate beam, and the first and second measurements are identical. Alternatively, the terminal can report both the measurement value of the current beam and the measurement value of the candidate beam. In this case, the first measurement value includes both the measurement value of the current beam and the measurement value of the candidate beam, while the second measurement value includes the measurement value of the candidate beam, and the first and second measurements are different. Finally, the terminal can report only the measurement value of the current beam. In this case, the first measurement value includes the measurement value of the current beam, while the second measurement value includes the measurement value of the candidate beam, and the first and second measurements are different.

[0122] For example, if the measurement value of the current beam corresponding to a port of a reference signal resource satisfies a trigger event, the terminal can report only the measurement value of the current beam corresponding to that port. In this case, both the first and second measurements include only the measurement value of the current beam corresponding to that port, and the first and second measurements are identical. Alternatively, the terminal can report the measurement value of the current beam corresponding to that port, as well as the measurement values ​​of other current beams or candidate beams. These other current beams can be the current beams corresponding to other ports of the same reference signal resource. In this case, the first measurement value includes the measurement values ​​of multiple current beams, corresponding to multiple ports, while the second measurement value includes the measurement value of one current beam; the first and second measurements are different. Or, the first measurement value includes the measurement values ​​of the current beam and candidate beams, while the second measurement value only includes the measurement value of the current beam; the first and second measurements are different. The terminal may also report only the measurement values ​​of other current beams or candidate beams. In this case, the first measurement value includes the measurement values ​​of other current beams or candidate beams, and the second measurement value includes the measurement value of the current beam that satisfies the trigger event. The first measurement value and the second measurement value are different.

[0123] For example, if the second measurement used to evaluate a triggering event is L1-RSRP, while the first measurement included in the report is L1-SINR or CSI, then the first and second measurements are different. For instance, L1-RSRP, L1-SINR, and CSI corresponding to the current beam can be measured. If L1-RSRP is lower than the first threshold value in the triggering event, L1-SINR or CSI can be reported in the report. As another example, L1-RSRP, L1-SINR, and CSI corresponding to a candidate beam can be measured. If L1-RSRP is higher than the second threshold value in the triggering event, L1-SINR or CSI can be reported in the report. It is understood that the examples given in this disclosure are merely illustrative and not limiting.

[0124] For example, if the second measurement value used to evaluate the triggering event is L1-RSRP, and the first measurement value included in the report is also L1-RSRP, then the first and second measurements are the same. For instance, the L1-RSRP corresponding to the current beam can be measured. If the L1-RSRP is lower than the first threshold value in the triggering event, L1-RSRP can be reported in the report. As another example, the L1-RSRP, L1-SINR, CSI, etc., corresponding to candidate beams can be measured. If the L1-RSRP is higher than the second threshold value in the triggering event, L1-RSRP can be reported in the report; if the L1-SINR is higher than the second threshold value in the triggering event, L1-SINR can be reported in the report. In other words, the second threshold value in the triggering event can be different for different types of measurements, or it can be the same second threshold value; this disclosure does not limit this.

[0125] For example, assume that reference signal resource #1 is a first reference signal resource, and reference signal resource #1 is a multi-port reference signal resource, and the ports corresponding to reference signal resource #1 include port #1-1 and port #1-2, and reference signal resource #2 is a second reference signal resource. If the measured value of the reference signal received by port #1-1 of reference signal resource #1 satisfies the trigger event, the second measured value is the measured value of the reference signal received by port #1-1 of reference signal resource #1, and the first measured value can be the measured value of the reference signal received by port #1-1 of reference signal resource #1, then the first measured value and the second measured value are the same. If the first measured value can be the measured value of the reference signal received by port #1-1 of reference signal resource #1, and the measured value of the reference signal received by port #1-2 of reference signal resource #1, then the first measured value and the second measured value are different. If the second measured value can be the measured value of the reference signal on reference signal resource #2, then the first measured value and the second measured value are different. This disclosure does not provide specific examples, but is not limited thereto.

[0126] In some embodiments, the third information includes at least one of the following: port identifier; port group identifier; antenna port identifier; antenna port group identifier; antenna subarray identifier; antenna element group identifier; CSI-RS port identifier; CSI-RS port group identifier; antenna identifier; antenna group identifier; Transmission Configuration Indicator (TCI state) identifier; TCI state group identifier; Control Resource Set Pool Index identifier; Transmission and Receiving Point (TRP) identifier.

[0127] In some embodiments, the ports in the various embodiments of this disclosure can be replaced by port groups, antenna ports, antenna port groups, antenna subarrays, antenna element groups, CSI-RS ports, CSI-RS port groups, etc. For example, the first reference signal resource is a multi-port reference signal resource, which can correspond to multiple port groups, and each port group can correspond to a current beam. As another example, the second reference signal resource is a multi-port reference signal resource, which can correspond to multiple antenna subarrays, and each antenna subarray can correspond to a candidate beam. This disclosure does not list all cases, but is not limited to them.

[0128] In some embodiments, if the reference signal resource is a single-port reference signal resource, different reference signal resources can correspond to different antennas. If the reference signal resource is a multi-port reference signal resource, different ports can correspond to different antennas.

[0129] In some embodiments, the triggering event includes at least one of the following: the second measurement value of the current beam is lower than a first threshold; the second measurement value of the candidate beam is higher than a second threshold; the second measurement value of the candidate beam is higher than the second measurement value of the current beam, and the difference between the second measurement value of the candidate beam and the second measurement value of the current beam is higher than a third threshold.

[0130] In some embodiments, the triggering event may include a second measurement value of the first beam being lower than a first threshold. The second measurement value of the first beam may include a second measurement value of a current beam, or the average of the second measurement values ​​of N current beams, where N is a positive integer greater than 1. For example, if the triggering event indicated by the first information includes a second measurement value of the first beam being lower than the first threshold, the terminal may measure the reference signal on the first reference signal resource to obtain a second measurement value of a current beam or N current beams. If the second measurement value of a current beam is lower than the first threshold, the triggering event is determined to be satisfied; or, if the second measurement values ​​of N current beams are lower than the first threshold, the triggering event is determined to be satisfied. If the triggering event is determined to be satisfied, the terminal may send a report to the network device. The content of the report may be as described in the above embodiments, and will not be repeated here. For example, the reference signal resource may be a single-port reference signal resource, and the terminal may have only one current beam; therefore, the second measurement value of the first beam may be the second measurement value of a single current beam. For example, the reference signal resource can be a multi-port reference signal resource, where each port can correspond to one current beam, and the reference signal resource can correspond to multiple current beams. In this case, the second measurement value of the first beam can be the second measurement value of one of the multiple current beams, or it can be the average of the second measurement values ​​of N current beams. For example, for a near-field terminal, the reference signal resource can be a multi-port reference signal resource. Alternatively, the reference signal resource can be a single-port reference signal resource, where each reference signal resource can correspond to one current beam, and multiple reference signal resources can correspond to multiple current beams. In this case, the second measurement value of the first beam can be the second measurement value of one of the multiple current beams, or it can be the average of the second measurement values ​​of N current beams.

[0131] For example, assume that reference signal resource #1 is a first reference signal resource, and that reference signal resource #1 is a multi-port reference signal resource, with ports including port #1-1 and port #1-2. A trigger event can be determined to be satisfied based on the measurement value of the current beam corresponding to port #1-1 being lower than a first threshold. For example, if the measurement value of the reference signal received at port #1-1 is lower than the first threshold, then a trigger event is determined to be satisfied. Similarly, a trigger event can be determined to be satisfied based on the measurement value of the current beam corresponding to port #1-2 being lower than the first threshold. For example, if the measurement value of the reference signal received at port #1-2 is lower than the first threshold, then a trigger event is determined to be satisfied. Alternatively, a trigger event can be determined to be satisfied based on the average value of the measurements at ports #1-1 and #1-2 being lower than the first threshold. For example, if the measured value of the reference signal received at port #1-1 is measured value 1-1, and the measured value of the reference signal received at port #1-2 is measured value 1-2, and the average value of measured value 1-1 and measured value 1-2 is lower than the first threshold value, then the trigger event is determined to be satisfied.

[0132] For example, assume that both reference signal resource #1 and reference signal resource #2 are first reference signal resources. A trigger event can be determined to be satisfied based on the measurement value of the current beam corresponding to reference signal resource #1 being lower than a first threshold. For example, if the measurement value of the reference signal received by reference signal resource #1 is lower than the first threshold, then the trigger event is determined to be satisfied. Similarly, a trigger event can be determined to be satisfied based on the measurement value of the current beam corresponding to reference signal resource #2 being lower than the first threshold. For example, if the measurement value of the reference signal received by reference signal resource #2 is lower than the first threshold, then the trigger event is determined to be satisfied. Alternatively, a trigger event can be determined to be satisfied based on the average of the measurement values ​​of reference signal resources #1 and #2 being lower than the first threshold. For example, if the measurement value of the reference signal received by reference signal resource #1 is measurement value 1-1, and the measurement value of the reference signal received by reference signal resource #2 is measurement value 1-2, and the average of measurement value 1-1 and measurement value 1-2 is lower than the first threshold, then the trigger event is determined to be satisfied.

[0133] It is understandable that, for a multi-port first reference signal resource, one port of the first reference signal resource corresponds to one current beam, and the first reference signal resource corresponds to multiple current beams. The second measurement value of the first beam can be the second measurement value of one beam among the multiple beams, or it can be the average of the second measurement values ​​of N beams among the multiple beams. Therefore, how to select this one or N current beams from the multiple current beams is a technical problem that needs to be solved. That is, which one or which N ports' corresponding current beams are used to evaluate whether they are below a first threshold value is a technical problem that needs to be solved. The information corresponding to the ports of the reference signal resource is third information. This disclosure provides a method for determining the third information corresponding to the first beam:

[0134] In some embodiments, the third information corresponding to the first beam is: specified third information, which is configured by the network device or predefined in the protocol; or, arbitrary third information, which is determined by the terminal; or, the third information corresponding to the minimum second measurement value, wherein the minimum second measurement value is the smallest second measurement value among multiple ports corresponding to the second measurement values, wherein the multiple ports are multiple ports corresponding to the indicated Transmission Configuration Indication State (indicated TCI state), each port corresponding to one second measurement value, and the second measurement value corresponding to one port is obtained based on the measurement of the reference signal received on the reference signal resource corresponding to the one port; or, the third information corresponding to the maximum second measurement value, wherein the maximum second measurement value is the largest second measurement value among multiple ports corresponding to the second measurement values, wherein the multiple ports are multiple ports corresponding to the indicated TCI state, each port corresponding to one second measurement value, and the second measurement value corresponding to one port is obtained based on the measurement of the reference signal received on the reference signal resource corresponding to the one port; or, the third information corresponding to the specified indicated TCI state, wherein the specified indicated TCI state is configured by the network device or predefined in the protocol.

[0135] Optionally, the third information corresponding to the first beam can be specified third information. The specified third information can be configured by the network device or predefined in the protocol. For example, the network device can be configured to specify one or more pieces of third information. The terminal can determine the specified third information based on the network device's configuration and determine whether the trigger event is satisfied based on whether the second measurement value of the current beam corresponding to the specified third information is lower than a first threshold. Alternatively, the protocol can predefine specified third information. The terminal can determine the specified third information based on the protocol and determine whether the trigger event is satisfied based on whether the second measurement value of the current beam corresponding to the specified third information is lower than a first threshold.

[0136] Optionally, the network device can directly configure the first beam in the trigger event as the first beam corresponding to the specified third information when configuring the trigger event. That is, the second measurement value of the first beam in the trigger event can be the second measurement value of the current beam corresponding to a specified third information, or the second measurement value of the first beam in the trigger event can be the average of the second measurement values ​​of the current beams corresponding to N specified third information. The trigger event can be caused by the second measurement value of the first beam corresponding to the specified third information being lower than a first threshold. The first beam corresponding to the third information can be a single current beam corresponding to one third information, or N current beams corresponding to N third information. Alternatively, the trigger event can be caused by the second measurement value of a single current beam corresponding to a specified third information being lower than a first threshold. Alternatively, the trigger event can be caused by the average of the second measurement values ​​of the N current beams corresponding to N specified third information being lower than a first threshold. Each specified third information corresponds to one current beam.

[0137] Optionally, when configuring the trigger event, the network device may not configure the first beam in the trigger event to be the first beam corresponding to the specified third information, but the terminal may determine the first beam in the trigger event to be the first beam corresponding to the specified third information according to the actual situation.

[0138] Optionally, the third information corresponding to the first beam can be any third information. This arbitrary third information is determined by the terminal. For example, the terminal can determine the third information corresponding to the first beam based on the actual situation.

[0139] Optionally, the third information corresponding to the first beam can be the third information corresponding to the minimum second measurement value. The minimum second measurement value is the smallest of the second measurement values ​​corresponding to multiple ports. The multiple ports are those corresponding to the indicated Transmission Configuration Indication (TCI) state. Each port corresponds to a second measurement value, and the second measurement value corresponding to a port is obtained based on the measurement of the reference signal received on the reference signal resource corresponding to that port. The indicated TCI state is configured by the network device for the terminal. The Quasi-Co Location (QCL) Type D of the indicated TCI state can indicate the first reference signal resource. For example, if the QCL Type D of the indicated TCI state indicates a Channel State Information-Reference Signal (CSI-RS) resource, and there is a quasi-colocation relationship between the CSI-RS and the Synchronization Signal Block (SSB), then the first reference signal resource can be either a CSI-RS resource or an SSB resource. It is understood that the first reference signal resource is a multi-port reference signal resource; that is, the first reference signal resource can correspond to multiple ports. Therefore, one indicated TCI state can correspond to one or more ports, and the port information is the third information. In other words, one indicated TCI state can correspond to one or more third information pieces. Multiple indicated TCI states correspond to multiple third information pieces. Among the multiple ports corresponding to one or more indicated TCI states, the port with the smallest second measurement value can be used as the port corresponding to the first beam. That is, the third information corresponding to the smallest second measurement value can be used as the third information corresponding to the first beam. It can be understood that the third information with the smallest second measurement value can be a single third information piece (in the case where the second measurement value of the first beam is the second measurement value of a current beam), or it can be the top N third information pieces sorted from smallest to largest second measurement value (in the case where the second measurement value of the first beam is the average of the second measurement values ​​of N current beams). The third information corresponding to the smallest second measurement value can be understood as the information of one or more ports with the smallest measurement value obtained by measuring the reference signal received from multiple ports.

[0140] For example, assume that the QCL Type D of the indicated TCI state indicates a CSI-RS resource. The terminal can determine that the CSI-RS resource is a first reference signal resource. If the CSI-RS resource is a multi-port reference signal resource, the terminal receives CSI-RS at multiple ports of the CSI-RS resource and measures multiple second measurement values. Assume that the ports corresponding to the CSI-RS include port #1-1, port #1-2, and port #1-3. The terminal receives CSI-RS at port #1-1 and measures second measurement value 1-1. Correspondingly, it receives CSI-RS at port #1-2 and measures second measurement value 1-2, and receives CSI-RS at port #1-3 and measures second measurement value 1-3. Assume that the second measurement values ​​are ordered from smallest to largest as second measurement value 1-2 < second measurement value 1-3 < second measurement value 1-1. It is understood that the above CSI-RS resource and port situation are merely exemplary, and this disclosure is not limited thereto.

[0141] In this exemplary case, if the number of third information items with the smallest second measurement value is one, that is, the second measurement value of the first beam is the second measurement value of a current beam, since the second measurement value 1-2 is the smallest second measurement value, the third information item corresponding to the first beam can be #1-2, that is, the corresponding port #1-2. If the second measurement value 1-2 is lower than the first threshold value, it can be determined that the trigger event is met, and the terminal can send a report to the network device.

[0142] In this exemplary case, if the number of third information items with the smallest second measurement value is N, that is, the second measurement value of the first beam is the average of the second measurement values ​​of N current beams (assuming N is 2), since the second measurement value 1-2 and the second measurement value 1-3 are the two smallest second measurement values ​​among the three second measurement values, the third information corresponding to the first beam can be #1-2 and #1-3, that is, corresponding to port #1-2 and port #1-3. If the average of the second measurement value 1-2 and the second measurement value 1-3 is lower than the first threshold value, it can be determined that the trigger event is met, and the terminal can send a report to the network device.

[0143] Optionally, the third information corresponding to the first beam can be the third information corresponding to the maximum second measurement value. The maximum second measurement value is the largest second measurement value among multiple ports corresponding to the second measurements. These multiple ports are ports corresponding to the indicated TCI state, each port corresponding to a second measurement value. The second measurement value for a port is obtained based on a measurement of the reference signal received on the reference signal resource corresponding to that port. That is, among the multiple ports corresponding to one or more indicated TCI states, the port with the largest second measurement value can be used as the port corresponding to the first beam. The port information is the third information; that is, the third information corresponding to the maximum second measurement value can be used as the third information corresponding to the first beam. It can be understood that the third information with the largest second measurement value can be a single piece of third information (in the case where the second measurement value of the first beam is the second measurement value of a current beam), or it can be the top N pieces of third information sorted from largest to smallest (in the case where the second measurement value of the first beam is the average of the second measurements of N current beams). The third information corresponding to the largest second measurement value can be understood as the identifier associated with one or more ports that have the largest measurement value after measuring the reference signal received from multiple ports. This identifier is the third information corresponding to the smallest second measurement value.

[0144] For example, assume that the QCL Type D of the indicated TCI state indicates a CSI-RS resource. The terminal can determine that the CSI-RS resource is a first reference signal resource. If the CSI-RS resource is a multi-port reference signal resource, the terminal receives CSI-RS at multiple ports of the CSI-RS resource and measures multiple second measurement values. Assume that the ports corresponding to the CSI-RS include port #1-1, port #1-2, and port #1-3. The terminal receives CSI-RS at port #1-1 and measures second measurement value 1-1. Correspondingly, it receives CSI-RS at port #1-2 and measures second measurement value 1-2, and receives CSI-RS at port #1-3 and measures second measurement value 1-3. Assume that the second measurement values ​​are ordered from smallest to largest as second measurement value 1-2 < second measurement value 1-3 < second measurement value 1-1. It is understood that the above CSI-RS resource and port situation are merely exemplary, and this disclosure is not limited thereto.

[0145] In this exemplary case, if the number of third information items with the largest second measurement value is one, that is, the second measurement value of the first beam is the second measurement value of a current beam, since the second measurement value 1-1 is the largest second measurement value, the third information item corresponding to the first beam can be #1-1, that is, the corresponding port #1-1. If the second measurement value 1-1 is lower than the first threshold value, it can be determined that the trigger event is met, and the terminal can send a report to the network device.

[0146] In this exemplary case, if the number of third information items with the largest second measurement value is N, that is, the second measurement value of the first beam is the average of the second measurement values ​​of N current beams (assuming N is 2), since the second measurement value 1-3 and the second measurement value 1-1 are the two largest second measurement values ​​among the three second measurement values, the third information corresponding to the first beam can be #1-3 and #1-1, that is, corresponding to port #1-3 and port #1-1. If the average of the second measurement value 1-3 and the second measurement value 1-1 is lower than the first threshold value, it can be determined that the trigger event is met, and the terminal can send a report to the network device.

[0147] Optionally, the third information corresponding to the first beam can be the third information corresponding to a specified indicated TCI state. For example, each indicated TCI state can correspond to one third information, and the third information corresponding to the first beam can be the third information corresponding to a specified indicated TCI state. Here, the specified indicated TCI state is configured in the network device or predefined in the protocol.

[0148] Optionally, the first beam can be the beam of the reference signal corresponding to the specified indicated TCI state. For example, if there are multiple indicated TCI states, and the specified indicated TCI state is the first indicated TCI state, then one or more beams corresponding to the CSI-RS in the first indicated TCI state can be used as the first beam, that is, as the current beam used to evaluate whether the trigger event is satisfied. Alternatively, one or more beams corresponding to the SSB that has a QCL relationship with the CSI-RS can be used as the current beam used to evaluate whether the trigger event is satisfied. For example, if the CSI-RS or SSB corresponds to one beam, the trigger event can be determined to be satisfied when the second measurement value corresponding to that beam is lower than the first threshold value. As another example, if the CSI-RS or SSB corresponds to multiple beams, the trigger event can be determined to be satisfied when the second measurement value of one of the multiple beams is lower than the first threshold value. Among these, one of the multiple beams can be determined in a similar manner to other embodiments of this disclosure, which will not be described in detail here. For example, if CSI-RS or SSB corresponds to multiple beams, a trigger event can be determined to be satisfied when the average of the second measurements of N beams among the multiple beams is lower than a first threshold. The N beams among the multiple beams can be determined in a similar manner to other embodiments of this disclosure, and will not be elaborated further here.

[0149] In some embodiments, the N current beams are the top N current beams of the terminal, sorted from largest to smallest according to the second measurement value, or the N current beams are the top N current beams of the terminal, sorted from smallest to largest according to the second measurement value.

[0150] For example, assume the first reference signal resource is a multi-port reference signal resource, and the corresponding ports include port #1-1, port #1-2, port #1-3, port #1-4, and port #1-5. The terminal receives the reference signal on the first reference signal resource at port #1-1 and measures the second measurement value 1-1. Correspondingly, it receives the reference signal on the first reference signal resource at port #1-2 and measures the second measurement value 1-2. The other ports are similarly measured, obtaining the second measurement values ​​1-3, 1-4, and 1-5 respectively. Assume the second measurement values ​​are ordered from smallest to largest as follows: second measurement value 1-2 < second measurement value 1-3 < second measurement value 1-1 < second measurement value 1-5 < second measurement value 1-4. Then, the order from largest to smallest is: second measurement value 1-4 > second measurement value 1-5 > second measurement value 1-1 > second measurement value 1-3 > second measurement value 1-2.

[0151] In this exemplary case, if N is 1, since the second measurement value 1-2 is the smallest second measurement value (i.e., the first second measurement value sorted from smallest to largest), the N current beams can be the current beams corresponding to ports #1-2. Since the second measurement value 1-4 is the largest second measurement value (i.e., the first second measurement value sorted from largest to smallest), the N current beams can be the current beams corresponding to ports #1-4.

[0152] In this exemplary case, if N is 2, since the second measurement values ​​1-2 and 1-3 are the first two second measurement values ​​sorted from smallest to largest, the N current beams can be the current beams corresponding to ports #1-2 and #1-3. Similarly, since the second measurement values ​​1-4 and 1-5 are the first two second measurement values ​​sorted from largest to smallest, the N current beams can be the current beams corresponding to ports #1-4 and #1-5.

[0153] In this exemplary case, if N is 3, since the second measurement values ​​1-2, 1-3, and 1-1 are the top 3 second measurement values ​​sorted from smallest to largest, the N current beams can be the current beams corresponding to ports #1-2, #1-3, and #1-1. Since the second measurement values ​​1-4, 1-5, and 1-1 are the top 3 second measurement values ​​sorted from largest to smallest, the N current beams can be the current beams corresponding to ports #1-4, #1-5, and #1-1.

[0154] This disclosure does not limit the size of N, nor is it limited to the examples given above.

[0155] In some embodiments, the size of N is configured in the network device or predefined in the protocol.

[0156] In some embodiments, the indicated TCI state in the above embodiments can be configured using at least one of RRC, MAC CE, and DCI. For example, if RRC configures only one TCI state for any third information, then that TCI state is the indicated TCI state corresponding to that third information. As another example, if RRC configures multiple indicated TCI states for any third information, but MAC CE activates only one, then the activated MAC CE is the indicated TCI state corresponding to that third information. As yet another example, if RRC configures multiple indicated TCI states for any third information, and MAC CE activates multiple states, then the DCI indicates the indicated TCI state corresponding to that third information.

[0157] In some embodiments, the triggering event may include a second measurement value of the second beam being higher than a second threshold value. The second measurement value of the second beam may include the second measurement value of a candidate beam, or the average of the second measurement values ​​of M candidate beams, where M is a positive integer greater than 1. For example, if the triggering event indicated by the first information includes a second measurement value of the second beam being higher than the second threshold value, the terminal can measure the reference signal on the second reference signal resource to obtain the second measurement value of the candidate beam. If the second measurement value of one candidate beam is higher than the second threshold value, the triggering event is satisfied. Alternatively, if the average of the second measurement values ​​of the M candidate beams is higher than the second threshold value, the triggering event is satisfied. If the triggering event is satisfied, the terminal can send a report to the network device. The content of the report is as described in the above embodiments, and will not be repeated here. For example, the network device can configure a set of reference signal resources for candidate beams for the terminal. The set of reference signal resources includes one or more second reference signal resources. One second reference signal resource may correspond to one candidate beam. Alternatively, one port of one second reference signal resource may correspond to one candidate beam. Therefore, for multi-port second reference signal resources, one second reference signal resource corresponds to multiple candidate beams. For example, for a near-field terminal, one port of a second reference signal resource can correspond to one candidate beam. If the set of reference signal resources includes only one second reference signal resource, and one second reference signal resource corresponds to one candidate beam, then the second measurement value of the second beam is the second measurement value of one candidate beam. If the set of reference signal resources includes multiple reference signal resources, and one reference signal resource corresponds to one or more candidate beams, then the second measurement value of the second beam can be the second measurement value of one of the multiple candidate beams, or it can be the average of the second measurement values ​​of M candidate beams.

[0158] In some embodiments, M and N can be the same or different.

[0159] It is understandable that, for a multi-port second reference signal resource, and where the measurement value of the second beam is the measurement value of a candidate beam, the technical problem to be solved is how to select this candidate beam from multiple candidate beams. In other words, for each port of the second reference signal resource corresponding to one candidate beam, determining which candidate beam corresponding to which port is used to evaluate whether it exceeds a second threshold value is a technical problem to be solved. Port information is considered third information, and the second beam corresponds to third information. This disclosure provides a method for determining the third information corresponding to the second beam:

[0160] In some embodiments, the third information corresponding to the second beam is: specified third information, which is configured by the network device or predefined in the protocol; or, arbitrary third information, which is determined by the terminal; or the third information corresponding to the minimum second measurement value, wherein the minimum second measurement value is the smallest second measurement value among multiple ports corresponding to the second measurement values, wherein the multiple ports are multiple ports corresponding to the indicated Transmission Configuration Indication State (indicated TCI state), each port corresponding to one second measurement value, and the second measurement value corresponding to one port is obtained based on the measurement of the reference signal received on the reference signal resource corresponding to the one port; or, the third information corresponding to the maximum second measurement value, wherein the maximum second measurement value is the largest second measurement value among multiple ports corresponding to the second measurement values, wherein the multiple ports are multiple ports corresponding to the indicated TCI state, each port corresponding to one second measurement value, and the second measurement value corresponding to one port is obtained based on the measurement of the reference signal received on the reference signal resource corresponding to the one port; or, the third information corresponding to the specified indicated TCI state, wherein the specified indicated TCI state is configured by the network device or predefined in the protocol.

[0161] It is understood that the method for determining the third information corresponding to the second beam is similar to the method for determining the third information corresponding to the current beam, and can be referred to the above embodiments for details, which will not be repeated here. For example, the indicated TCI state can indicate the second reference signal resource. If the second reference signal resource is a multi-port reference signal resource, then the indicated TCI state can correspond to multiple third information. In this case, the third information corresponding to the second beam can be the third information with the smallest second measurement value among the multiple third information, or the third information with the largest second measurement value among the multiple third information. As another example, the indicated TCI state can indicate the second reference signal resource. If the reference signal resource set of the candidate beam includes multiple second reference signal resources, and each second reference signal resource is a single-port second reference signal resource, corresponding to one third information, then different indicated TCI states can correspond to different third information. In this case, the third information corresponding to the second beam can be the third information corresponding to the specified indicated TCI state, which is configured in the network device or predefined in the protocol.

[0162] Optionally, when there are multiple indicated TCI states, the specified indicated TCI state can be the first indicated TCI state. The first indicated TCI state may include third information, in which case the candidate beam corresponding to the specified first indicated TCI state can be the candidate beam corresponding to that third information; or the candidate beam corresponding to the specified first indicated TCI state can be a candidate beam belonging to the same reference signal resource set as the CSI-RS in the first indicated TCI state. Alternatively, the candidate beam corresponding to the specified first indicated TCI state can be a candidate beam belonging to the same reference signal resource set as the SSB. Here, the SSB and the CSI-RS in the first indicated TCI state have a QCL relationship. Alternatively, the candidate beam corresponding to the specified first indicated TCI state can be determined based on a reference signal resource, which corresponds to the same TRP as the CSI-RS in the first indicated TCI state, and the candidate beam corresponding to the first indicated TCI state can be the candidate beam corresponding to that reference signal resource.

[0163] Optionally, the network device can directly configure the second beam in the trigger event as the second beam corresponding to the specified third information when configuring the trigger event. That is, the second measurement value of the second beam in the trigger event can be the second measurement value of a candidate beam corresponding to a specified third information, or the second measurement value of the second beam in the trigger event can be the average of the second measurement values ​​of N candidate beams corresponding to specified third information. The trigger event can be caused by the second measurement value of the second beam corresponding to the specified third information being higher than a second threshold. The second beam corresponding to the third information can be a single candidate beam corresponding to one third information, or N candidate beams corresponding to N third information. Alternatively, the trigger event can be caused by the second measurement value of a single candidate beam corresponding to a specified third information being higher than a second threshold. Alternatively, the trigger event can be caused by the average of the second measurement values ​​of N candidate beams corresponding to N specified third information being higher than a second threshold. Each specified third information corresponds to one candidate beam.

[0164] Optionally, when configuring the trigger event, the network device may not configure the second beam as the second beam corresponding to the specified third information, but the terminal may determine the second beam in the trigger event as the second beam corresponding to the specified third information based on the actual situation.

[0165] In some embodiments, the M candidate beams are the top M candidate beams among all candidate beams of the terminal, sorted from largest to smallest according to the second measurement value; or, the M candidate beams are the top M candidate beams among all candidate beams of the terminal, sorted from smallest to largest according to the second measurement value.

[0166] It is understood that the method for determining the M candidate beams is similar to the method for determining the N current beams, and can be referred to the above embodiments, which will not be repeated in this disclosure.

[0167] In some embodiments, the size of M is configured in the network device or predefined in the protocol.

[0168] In some embodiments, the triggering event may include a second measurement value of the second beam being higher than a second measurement value of the first beam, and the difference between the second measurement value of the second beam and the second measurement value of the first beam being higher than a third threshold. The second measurement value of the first beam may include a second measurement value of a current beam, or the average of N second measurement values ​​of current beams, where N is a positive integer greater than 1. The second measurement value of the second beam may include a second measurement value of a candidate beam, or the average of M second measurement values ​​of candidate beams, where M is a positive integer greater than 1. For example, if the triggering event indicated by the first information includes a second measurement value of the second beam being higher than a second measurement value of the first beam, and the difference between the second measurement value of the second beam and the second measurement value of the first beam being higher than a third threshold, the terminal may measure the reference signal on the first reference signal resource and the reference signal on the second reference signal resource respectively to obtain the second measurement value of the current beam and the second measurement value of the candidate beam. If the second measurement value of a candidate beam is higher than the second measurement value of a current beam, and the difference between the second measurement value of the candidate beam and the second measurement value of the current beam is higher than a third threshold, then the triggering event is determined to be satisfied. Alternatively, if the average of the second measurements of the N current beams is higher than the average of the second measurements of the M candidate beams, and the difference between the average of the second measurements of the N current beams and the average of the second measurements of the M candidate beams is higher than a third threshold, then the trigger event is determined to be satisfied. If the trigger event is determined to be satisfied, the terminal can send a report to the network device. The content of the report can be as described in the above embodiments, and will not be repeated here. The second measurements of the candidate beams and the measurements of the current beams are similar to those in the above trigger event, and will not be repeated here.

[0169] In some embodiments, if the triggering event includes a second measurement value of the second beam being higher than a second measurement value of the first beam, and the difference between the second measurement value of the second beam and the second measurement value of the first beam being higher than a third threshold, the first beam and the second beam in the triggering event may correspond to the same third information. For example, a third piece of information can be determined, and the first beam and the second beam corresponding to the third information are used to evaluate whether the event is satisfied. For example, if a third piece of information is determined, and the second measurement value of the second beam corresponding to the third information is higher than the second measurement value of the first beam corresponding to the third information, and the difference is higher than a third threshold, then the triggering event is determined to be satisfied.

[0170] In some embodiments, if the triggering event includes a second measurement value of the second beam being higher than a second measurement value of the first beam, and the difference between the second measurement value of the second beam and the second measurement value of the first beam being higher than a third threshold, the first beam and the second beam in the triggering event may correspond to different third information. For example, two pieces of third information may be determined, and the event may be evaluated based on the first beam corresponding to one piece of third information and the second beam corresponding to the other piece of third information. For example, if two pieces of third information are determined, and the second measurement value of the first beam corresponding to one piece of third information is higher than the second measurement value of the second beam corresponding to the other piece of third information, and the difference is higher than a third threshold, then the triggering event is determined to be satisfied.

[0171] In some embodiments, the first threshold, the second threshold, and the third threshold may be the same or different.

[0172] In some embodiments, at least one of the first threshold value, the second threshold value, and the third threshold value may be configured by the network device or may be predefined by the protocol.

[0173] In some embodiments, the first information includes at least one of the following: a trigger event; a threshold value corresponding to the trigger event, the threshold value including at least one of a first threshold value, a second threshold value, and a third threshold value; and a third identifier, the third identifier being used to indicate an association relationship, wherein at least one of the following values ​​is different in different association relationships: trigger event, threshold value corresponding to the trigger event, reference signal resource, reference signal resource set, and first measurement value type.

[0174] Optionally, the first information includes a triggering event. For example, the first information may include a triggering event, i.e., the triggering event may be explicitly indicated.

[0175] Optionally, the first information includes a threshold value corresponding to the triggering event. For example, if the triggering event is a second measurement value of the first beam that is lower than the first threshold value, the first information may include the first threshold value. If the first information includes the first threshold value, it may also implicitly indicate that the second measurement value of the triggering event is the first beam that is lower than the first threshold value. As another example, if the triggering event is a second measurement value of the second beam that is higher than the second threshold value, the first information may include the second threshold value. If the first information includes the second threshold value, it may also implicitly indicate that the second measurement value of the triggering event is the second beam that is higher than the second threshold value. As yet another example, if the triggering event is a second measurement value of the second beam that is higher than the second measurement value of the first beam, and the difference between the second measurement value of the second beam and the second measurement value of the first beam is higher than a third threshold value, the first information may include the third threshold value. If the first information includes the third threshold value, it may also implicitly indicate that the triggering event is the second measurement value of the second beam that is higher than the second measurement value of the first beam, and the difference between the second measurement value of the second beam and the second measurement value of the first beam is higher than the third threshold value.

[0176] Optionally, the first information includes a third identifier. The third identifier is used to indicate the association relationship, and the values ​​of at least one of the following are different in different association relationships: trigger event, threshold value corresponding to the trigger event, reference signal resource, set of reference signal resources, and type of first measurement value.

[0177] For example, one association is: the trigger event value is the second measurement value of the first beam being lower than the first threshold value; the threshold value corresponding to the trigger event, i.e., the first threshold value is X; the reference signal resource value is reference signal resource #1, which can correspond to the first beam; the reference signal resource set value is reference signal resource set #2, which can correspond to the second beam; the first measurement value type is L1-RSRP, and this association corresponds to the third identifier #1. Another association is: the trigger event value is the second measurement value of the second beam being higher than the second threshold value; the threshold value corresponding to the trigger event, i.e., the second threshold value is Y; the reference signal resource value is reference signal resource #3, which can correspond to the first beam; the reference signal resource set value is reference signal resource set #4, which can correspond to the second beam; the first measurement value type is L1-RSRP, and this association corresponds to the third identifier #2.

[0178] For example, if the first information includes the third identifier #1, the terminal can determine that the triggering event is that the second measurement value of the first beam is lower than the first threshold value, where the first threshold value is X, and the reference signal resource corresponding to the first beam is reference signal resource #1, the reference signal resource corresponding to the second beam is reference signal resource #2 in the reference signal resource set #2, and the type of the first measurement value is L1-RSRP. That is, the terminal can measure the reference signal on reference signal resource #1, or receive and measure the reference signal on reference signal resource #1 at one or N ports of reference signal resource #1, thereby obtaining the L1-RSRP corresponding to one or more current beams. If the L1-RSRP of a current beam is less than X, or the average value of the L1-RSRPs of multiple current beams is less than X, then the triggering event is determined to be satisfied, and the terminal sends a report to the network device.

[0179] For example, if the first information includes the third identifier #2, the terminal can determine that the triggering event is that the second measurement value of the second beam is higher than the second threshold value, the second threshold value is Y, and the reference signal resource corresponding to the second beam is reference signal resource #4 in reference signal resource set #4, and the type of the first measurement value is L1-RSRP. That is, the terminal can measure the reference signal on reference signal resource #4, or receive and measure the reference signal on reference signal resource #1 at one or N ports of reference signal resource #4, thereby obtaining the L1-RSRP corresponding to one or more candidate beams. If the L1-RSRP of a candidate beam is greater than Y, or the average value of the L1-RSRP of multiple candidate beams is greater than Y, then the triggering event is determined to be satisfied, and the terminal sends a report to the network device.

[0180] It is understood that the values ​​of each item in different associations may be partially the same or completely different. For example, in the example above, the type of the first measurement value is the same in the association corresponding to the third identifier #1 and the association corresponding to the third identifier #2, while the values ​​of the other items are all different. However, the above example is only an exemplary case, and this disclosure is not limited thereto.

[0181] In some embodiments, the first measurement value includes at least one of the following: a first measurement value of the serving cell; and a first measurement value of other cells besides the serving cell. For example, other cells besides the serving cell may be neighboring cells of the serving cell. For example, the terminal may report the first measurement value of the serving cell to the network device, such as reporting the measurement value of the current beam of the serving cell, the measurement value of the candidate beam of the serving cell, etc. As another example, the terminal may report the first measurement value of neighboring cells to the network device, such as reporting the measurement value of the current beam of the neighboring cell, the measurement value of the candidate beam of the neighboring cell, etc., thereby enabling the network device to more comprehensively consider the beam situation of the terminal's serving cell and other cells besides the serving cell, which facilitates better beam indication, beam switching, and cell handover and reselection, etc.

[0182] In some embodiments, the first information may further include at least one of the following: an identifier of the serving cell; and identifiers of other cells besides the serving cell. For example, if the first information includes the identifier of the serving cell, the terminal may send a report based on the current beam and / or candidate beam of the serving cell satisfying a trigger event. Alternatively, the terminal may report a first measurement value corresponding to the serving cell. Again, for example, if the first information includes the identifier of other cells besides the serving cell, the terminal may send a report based on the current beam and / or candidate beam of that cell satisfying a trigger event. Alternatively, the terminal may report a first measurement value corresponding to that cell.

[0183] In some embodiments, the current beam may also be referred to as the serving beam.

[0184] In some embodiments, the candidate beam may also be referred to as the new beam or the target beam.

[0185] In some embodiments, a beam can be referred to as quasi-co-location (QCL) Type D, spatial Rx parameter or spatial reception parameter, spatial Tx parameter or spatial transmission parameter, spatial setting, spatial relation info, spatial reception filter, spatial transmission filter, spatial domain filter, TCI state, indicated TCI state, joint TCI state, downlink TCI state, uplink TCI state, unified TCI state, common TCI state, etc.

[0186] In some embodiments, the name of the first information is not limited, and it may be, for example, "instruction information", "configuration information", etc.

[0187] In step S2102, terminal 101 determines the second measurement value of the first beam and / or the second measurement value of the second beam.

[0188] In some embodiments, if the triggering event indicated by the first information is that the second measurement value of the first beam is lower than a first threshold, the terminal can determine the second measurement value of the first beam. If the triggering event indicated by the first information is that the second measurement value of the second beam is higher than a second threshold, the terminal can determine the second measurement value of the second beam. If the triggering event indicated by the first information includes both of the above triggering events, the terminal can determine the second measurement value of the first beam and the second measurement value of the second beam. If the triggering event indicated by the first information is that the second measurement value of the second beam is higher than the second measurement value of the first beam, and the difference between the second measurement value of the second beam and the second measurement value of the first beam is higher than a third threshold, the terminal can determine the second measurement value of both the first beam and the second measurement value of the second beam.

[0189] In some embodiments, the second measurement of the first beam is obtained based on measurements of any of the following: a first CSI-RS, the first CSI-RS being a CSI-RS indicated by a quasi-co-location type D of an indicated TCI state; a first synchronization signal block SSB, the first SSB having a quasi-co-location relationship with the first CSI-RS; a second CSI-RS, the second CSI-RS being a CSI-RS used for mobility measurements; a second SSB, the second SSB being an SSB associated with the second CSI-RS; and a resource element RE corresponding to third information, the third information including third information corresponding to at least one of the following: the first CSI-RS, the first SSB, the second CSI-RS, and the second SSB.

[0190] Optionally, the second measurement value of the first beam is obtained based on a measurement of the first CSI-RS. The first CSI-RS is a QCL Type D-indicated CSI-RS with an indicated TCI state, where the indicated TCI state can be used to indicate the reference signal resource corresponding to the first beam. That is, the first CSI-RS corresponds to the first beam, and measuring the first CSI-RS can obtain the second measurement value corresponding to the first beam. For example, if the first CSI-RS resource is a single-port reference signal resource, then measuring the first CSI-RS can obtain a measurement value corresponding to the first beam.

[0191] Optionally, the second measurement value of the first beam is obtained based on the measurement of the first SSB, which has a quasi-co-addressable relationship with the first CSI-RS. In other words, the first SSB is the SSB of the QCL resource of the first CSI-RS. Therefore, the first beam corresponding to the first CSI-RS is also the first beam corresponding to the first SSB, and the second measurement value corresponding to the first beam can be obtained by measuring the first SSB. For example, if the first SSB resource is a single-port reference signal resource, a measurement value corresponding to the first beam can be obtained by measuring the first SSB.

[0192] Optionally, the second measurement value of the first beam is obtained based on a measurement of the second CSI-RS, which is a CSI-RS used for mobility measurements. For example, the second CSI-RS is used for mobility management to determine the random access occasion (RO) and preamble during the random access process. For instance, during random access, the terminal can perform channel quality measurements based on the CSI-RS to select the RO and preamble corresponding to the SSB associated with the best CSI-RS, and send the best preamble on the best RO to initiate random access. The CSI-RS corresponding to the best RO and the best preamble is the second CSI-RS, which is also the CSI-RS corresponding to the terminal's first beam after random access is completed. Therefore, the second measurement value corresponding to the first beam can be obtained by measuring the second CSI-RS.

[0193] For example, a second measurement value of the first beam can be obtained based on a second CSI-RS measurement even when the terminal is not configured with an indicated TCI state.

[0194] Optionally, the second measurement value of the current beam is obtained based on the measurement of the second SSB, which is the SSB associated with the second CSI-RS. Since the second SSB is associated with the second CSI-RS, the current beam corresponding to the second CSI-RS is also the current beam corresponding to the second SSB. By measuring the second SSB, the second measurement value corresponding to the first beam can be obtained.

[0195] For example, a second measurement value of the first beam can be obtained based on a second CSI-RS measurement even when the terminal is not configured with an indicated TCI state.

[0196] Optionally, the second measurement value of the first beam is obtained based on the measurement of the resource element RE corresponding to the third information, which includes at least one of the following third information: first CSI-RS, first SSB, second CSI-RS, and second SSB.

[0197] For example, if the first CSI-RS resource is a multi-port reference signal resource, then one or more second measurement values ​​corresponding to the current beam can be obtained by measuring the resource elements (REs) corresponding to one or N ports in the multi-port resource. Here, an RE can be a subcarrier on a symbol, but is not limited to this. The REs corresponding to one or N ports of the first CSI-RS resource are equivalent to one or N third pieces of information corresponding to the first CSI-RS. In other words, if the first CSI-RS resource is a multi-port reference signal resource, then one or more second measurement values ​​corresponding to one or N third pieces of information corresponding to the first CSI-RS resource can be obtained by measuring the REs.

[0198] For example, the ports corresponding to the first CSI-RS resource are port #1-1, port #1-2, and port #1-3, respectively. Port #1-1 corresponds to RE #1 (e.g., symbol 1 + subcarrier 1), and the third information corresponding to port #1-1 is #1-1. Port #1-2 corresponds to RE #2 (e.g., symbol 1 + subcarrier 2), and the third information corresponding to port #1-2 is #1-2. Port #1-3 corresponds to RE #3 (e.g., symbol 1 + subcarrier 3), and the third information corresponding to port #1-3 is #1-3. That is, third information #1-1 corresponds to RE #1 and corresponds to a current beam. Third information #1-2 corresponds to RE #2 and corresponds to a current beam. Third information #1-3 corresponds to RE3 and corresponds to a current beam. The terminal can measure RE #1 corresponding to third information #1-1 to obtain a second measurement value for a current beam. The terminal can measure RE2 corresponding to the third information #1-2 to obtain a second measurement value for the current beam. The terminal can measure RE#1 and RE2 corresponding to the third information #1-1 and the third information #1-2 to obtain the second measurement values ​​for the two current beams, and calculate the average value as the second measurement value for the first beam, that is, evaluate whether the trigger event is satisfied based on the average value.

[0199] It is understood that the above examples of REs are examples of REs with the same symbol corresponding to different ports of the same CSI-RS resource, but this disclosure is not limited to this and the symbols may also be different.

[0200] It is understandable that measuring the RS refers to measuring the received power on the RE where the RS is located. When the RS corresponds to a single port, measuring the RS means measuring the received power on all REs occupied by the RS. If the RS is a multi-port reference signal resource, measuring the values ​​of different ports means measuring the power on the REs occupied by different ports of the RS respectively.

[0201] It is understood that at least one of the first SSB, the second CSI-RS, and the second SSB corresponds to the third information. An example of how the RE corresponding to the third information is used to measure the current beam can be found in the first CSI-RS, which will not be repeated here.

[0202] In some embodiments, the terminal can determine a second measurement value of a candidate beam based on a second reference signal resource in the reference signal resource set corresponding to the candidate beam configured in the network device. For example, the second measurement value of the candidate beam can be obtained by measuring the reference signal on the second reference signal resource. Alternatively, the second measurement value of one or N candidate beams can be obtained by measuring the reference signal received at one or N ports of the second reference signal. The second measurement value of one candidate beam, or the average of the second measurement values ​​of N candidate beams, is used to evaluate whether a trigger event is satisfied.

[0204] In some embodiments, network device 102 receives a report sent by terminal 101.

[0248] This disclosure provides a method for defining events that trigger beam reporting by a near-field terminal, as follows:

[0249] In some embodiments, the terminal receives first information, which is used to indicate a triggering event. The triggering event is used to trigger a first report. The first report includes at least one of the following: Reference Signal IDentity (RS ID) (for example, it may be the second information in the above embodiments), L1-RSRP / L1-SINR, and third information (IDentity, ID).

[0250] In some embodiments, the second ID includes at least one of the following: port ID, port group ID, antenna port ID, antenna port group ID, antenna subarray ID, antenna element group ID, CSI-RS port ID, CSI-RS port group ID, antenna ID, and antenna group ID.

[0251] Alternatively, in this case, the reference signal resource used for beam scanning is a multi-port resource, corresponding to different antennas.

[0252] In some embodiments, the second ID further includes: TCI state ID, TCI state group ID, CORESETPoolIndex ID, TRP ID, and resource set ID.

[0253] Alternatively, in this case, the reference signal resource used for beam scanning is a single-port resource, and different reference signals correspond to different antennas, antenna panels, or antenna subarrays.

[0254] In some embodiments, the triggering event includes at least one of the following:

[0255] a) The measured value of the reference signal resource corresponding to the current beam is below the threshold;

[0256] b) The measured value of the reference signal resource of the current beam corresponding to the specified second ID is lower than the threshold;

[0257] c) The measured value of the reference signal resource of the candidate beam is higher than the threshold;

[0258] d) The measured value of the reference signal resource of the candidate beam for the specified second ID is higher than the threshold;

[0259] e) The measured value of the reference signal resource of the candidate beam is higher than the measured value of the reference signal resource of the current beam by an offset value;

[0260] f) The measured value of the reference signal resource of the first candidate beam with the second ID is higher than the measured value of the reference signal resource of the current beam with the second ID by one offset.

[0261] In some embodiments, in the conventional method, there is only one current beam, namely the CSI-RS indicated by QCL Type D corresponding to the indicated TCI state by the base station, or the SSB of the QCL source of that CSI-RS. This CSI-RS or SSB serves as the current reference signal resource. However, in 6G near-field applications, as described in the background, different second IDs correspond to different optimal transmission beams. Therefore, an enhancement to the definition of the current beam is proposed, including at least one of the following:

[0262] a) The current beam corresponding to the specified second ID is the current beam. For example, the specified second ID is the base station configuration, such as indicated in the first information.

[0263] b) The current beam corresponding to the default second ID is the current beam. For example, the protocol may agree on a default second ID, such as the current beam corresponding to the second ID with the smallest ID.

[0264] c) The current beam corresponding to any second ID is the current beam. For example, the terminal determines it itself.

[0265] d) Among all second IDs, the lowest measured value is taken as the measured value of the current beam. For example, the terminal measures the current beam corresponding to all second IDs and finds that the lowest measured value is below a threshold, thus satisfying the event.

[0266] e) Among all second IDs, the measurement value with the highest value is taken as the measurement value of the current beam. For example, if the terminal measures the current beam corresponding to all second IDs and finds that the measurement value with the highest value is below a threshold, then the event is satisfied.

[0267] f) The average of N measurements across all second IDs is used as the measurement value for the current beam. For example, if the terminal measures the current beam corresponding to all second IDs and finds that the average of the N measurements is below a threshold, the event is satisfied. For example, the value of N is configured by the base station or agreed upon by the protocol; if the base station does not configure it, N is 1. N represents either the largest or smallest number of measurements. N is less than or equal to the number of second IDs for which the base station has configured beams for the terminal.

[0268] It should be noted that the second ID mentioned above includes the second ID for which the base station has configured the indicated TCI state for the terminal. This applies to cases where the terminal has already been configured with the indicated TCI state. The base station configures the indicated TCI state for the terminal through at least one of RRC, MAC, CE, and DCI.

[0269] In some embodiments, if RRC configures only one TCI state for any second ID, then that TCI state is an indicated TCI state.

[0270] In some embodiments, for any second ID, RRC is configured with multiple indicated TCI states, while MAC CE is only activated with one. The one activated by MAC CE is the indicated TCI state.

[0271] In some embodiments, for any second ID, RRC is configured with multiple indicated TCI states, and MAC CE is activated with multiple states, then the one indicated by DCI is an indicated TCI state.

[0272] In some embodiments, if the beams corresponding to different second IDs are beams of different ports of the same reference signal resource, that is, the reference signal resource is also a multi-port reference signal resource, and each port can indicate a different beam, then when the terminal measures the measurement value of each second ID, it only measures the RE corresponding to the second ID to obtain the measurement value, and one RE corresponds to one subcarrier on one symbol.

[0273] In some embodiments, if the terminal is not configured with an indicated TCI state by the base station, the terminal selects the SSB or CSI-RS of the RO (RACH occasion) and preamble as the RS for the current beam to be measured during the random access process, or the RE corresponding to a certain second ID of the SSB or CSI-RS as the RE for the current beam to be measured.

[0274] In some embodiments, compared to triggering event a), triggering event b) is an event directly configured by the base station, which is specific to the second ID.

[0275] In some embodiments, if the second ID is configured with an indicated TCI state, the RS used for measurement by the current beam is the CSI-RS of QCL Type D with the indicated TCI state, or the SSB of the QCL source of the CSI-RS, or the RE of the second ID corresponding to the SSB or CSI-RS. Otherwise, during the terminal random access process, the SSB or CSI-RS of the selected RO (RACH occasion) and preamble on the second ID determined is used as the RS used for measurement by the current beam, or the RE of the second ID corresponding to the SSB or CSI-RS.

[0276] In some embodiments, a candidate beam is defined as follows: the base station configures a reference signal resource set corresponding to a new beam for the terminal. One reference signal resource corresponds to one new beam, or a second ID of a reference signal resource corresponds to one candidate beam. For different events, the base station can configure one or more reference signal resource sets corresponding to new beams (configurable through first information), and simultaneously configure the current beam information corresponding to the new beam reference signal resource set. That is, if the terminal has multiple current beams, the base station can configure multiple new beam reference signal resource sets, corresponding one-to-one with the multiple current beams. Alternatively, it can configure one new beam reference signal resource set, and the terminal determines the current beam corresponding to that reference signal resource set itself.

[0277] In some embodiments, the definition of the candidate beam is the same as the definition of the current beam, and will not be repeated here.

[0278] In some embodiments, the second ID of the candidate beam can correspond one-to-one with the second ID of the current beam. For example, if the current beam is the measurement value corresponding to the specified second ID, then the candidate beam is also the measurement value corresponding to the same second ID.

[0279] In some embodiments, the second ID of the candidate beam and the second ID of the current beam can be arbitrarily combined. For example, if the current beam is the measurement value corresponding to a specified second ID, then the candidate beam can also be the measurement value corresponding to a different second ID, or the maximum measurement value, or the minimum measurement value, or the average of N measurement values, etc.

[0280] In some embodiments, for triggering events e) and f), the two second IDs may be the same or different.

[0281] In some embodiments, the first information includes at least one of the following:

[0282] a) Configure RRC signaling to trigger events, as well as related thresholds, offsets, etc. The terminal then reports the event when it meets the trigger conditions.

[0283] b) Or RRC signaling configuration trigger event, and related thresholds, offset, etc., and then after MAC CE activation or DCI indication event ID or configID, the terminal will report when the trigger event is met.

[0284] Optionally, an association can also be configured during RRC configuration. For example, the trigger event and its associated threshold or offset can be associated with a reference signal resource or resource set (including CMR and / or IMR; the reference signal resource can be periodically, semi-persistent, or non-periodically transmitted), and with the reported measurement L1-RSRP or L1-SINR, the reporting type (semi-persistent or non-periodic transmission report), and an associated ID. Then, MAC CE or DCI can directly activate or indicate the ID. If it is a DCI indication, the CSI request field can be directly reused or extended.

[0285] In some embodiments, after the triggering condition is met, a report can be submitted once or multiple times, and the time interval between each report can be configured.

[0286] In some embodiments, the first report may include the beam value of the serving cell, or a cell other than the serving cell, such as a neighboring cell whose Physical Cell ID (PCI) is configured for the terminal.

[0287] In some embodiments, the first report may include a serving cell index and cell identifiers of neighboring cells.

[0288] This disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0289] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0290] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).

[0291] Figure 6a is a schematic diagram of the terminal structure proposed in an embodiment of this disclosure. As shown in Figure 6a, the terminal 6100 may include at least one of a transceiver module 6101 and a processing module 6102.
