[0069] In some embodiments, the acquisition of data, information, etc., may comply with the laws and regulations of the country where the location is situated.

[0071] 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.

[0072] Currently, the considerations are for base station configurations that provide periodic, semi-persistent, or non-periodic beam measurement reports.

[0073] However, changes in beam quality are actually the most timely information that terminals can obtain. For periodic beam measurement reports, the period length configured by the base station, or for non-periodic beam reports, the timing of non-periodic reporting, may not be optimal. For example, with periodic reporting, if the period is configured too short, the optimal K beams reported in two separate reports might be the same, with little change, wasting signaling. If the period is configured too long, beam changes might occur before the reporting time, affecting communication quality. Similarly, with non-periodic beam reporting, the base station might trigger the terminal to report too early or too late, which is not the most suitable timing.

[0074] In some embodiments, beam measurement reports can be triggered based on an event. Events include, but are not limited to, any of the following:

[0075] Event 1: The current beam quality is below a threshold;

[0076] Event 2: The beam quality of the new beam is higher than the current beam by one threshold;

[0077] Event 3: The current beam quality is below one threshold, and the new beam quality is above another threshold;

[0078] Event 4: The beam quality of the new beam is above a threshold;

[0079] Event 5: The beam quality of the new beam is higher than a threshold of an active beam.

[0080] The current beam described above is the serving beam, determined by the Channel State Information-Reference Signal (CSI-RS) indicated by the indicated Transmission Configuration Indication State (TCIstate) or the Synchronization Signal Block (SSB) of the Quasi-Co Location (QCL) resource of the indicated TCI-RS. The active beam corresponds to the activated TCI state, and its Reference Signal (RS) is determined by the SSB of the QCL source of the activated TCI-RS or the indicated TCI-RS.

[0081] The threshold values ​​for each of the above events can be the same or different.

[0082] Before a terminal can send a beam report, it must meet the following condition: the same new beam and / or the current beam must satisfy the same event in one or more evaluations. More specifically, the beam quality must satisfy the same event in M ​​evaluations within a time window. The beam report can include the beam quality corresponding to the new beam and / or the current beam; what it includes depends on which event it corresponds to.

[0083] In some embodiments, beam reports are transmitted based on the Physical Uplink Shared Channel (PUSCH), and prior to the PUSCH, the terminal may transmit information on the PUCCH. This information may be used to request a Dynamic Grant (DG) PUSCH (i.e., DCI-scheduled) resource (mode A), or to indicate that a beam report will be transmitted on the first Type I Configured Grant (CG) PUSCH (a periodically configured PUCCH resource) resource following the next first quantity symbol (mode B).

[0084] In some embodiments, the format of the beam report for Event 2 is as shown in Table 1.

[0085] Table 1

[0086]

[0087] CRI / SSBRI are both Reference Signal IDs (RSIDs) for the new beam, including CSI-RS ID or SSB ID. Following the N RS IDs are the L1-RSRPs corresponding to those N RS IDs. The value corresponding to the first RSID is L1-RSRP#1, which is the actual value of the L1-RSRP, or absolute value (i.e., not a relative difference). The L1-RSRPs corresponding to the other RSIDs are differential L1-RSRPs, that is, the difference between the actual value of the L1-RSRP for the other RSIDs and the L1-RSRP for the first RSID.

[0088] The last Differential L1-RSRP corresponds to the current beam, which is the difference between the L1-RSRP of the current beam and the L1-RSRP of the first RS ID. Since Event 2's condition is that the new beam is higher than the current beam by a threshold, the quality of the current beam is definitely lower than the new beam. Furthermore, this Differential L1-RSRP of the current beam is only required when the RRC is configured to report it; otherwise, it does not need to be reported.

[0089] However, for Event 1, the condition is that the current beam is below a threshold, and the network also configures a reference signal resource set corresponding to the new beam. When Event 1 is satisfied, the terminal will also measure the new beam in the reference signal resource set and then report the beam. However, it is uncertain whether the current beam quality or the new beam quality is better. Therefore, how to report the beam corresponding to Event 1 in this case is a problem that needs to be solved.

[0090] Therefore, this disclosure provides a communication method in which a terminal sends a report triggered by an event, namely, the quality of the current beam is lower than a first threshold. The report may include a first differential quality, which is the difference between the quality of the current beam and the first threshold. This enables the design of the report content when the event is that the quality of the current beam is lower than the first threshold, thereby improving communication efficiency.

Event 2 is a new beam quality that is higher than the current beam quality, and the difference between the new beam quality and the current beam quality being greater than a third threshold.

[0113] For example, an event could include the current beam quality being below the second threshold and the new beam quality being above the fourth threshold. Event 3 would be the current beam quality being below the second threshold and the new beam quality being above the fourth threshold.

[0114] For example, an event could include the new beam's beam quality being higher than the fourth threshold, with Event 4 being the new beam's beam quality being higher than the fourth threshold.

[0115] For example, an event could include a new beam quality that is higher than the active beam quality, and the difference between the new beam quality and the active beam quality being greater than a fifth threshold. Event 5 is defined as a new beam quality that is higher than the active beam quality, and the difference between the new beam quality and the active beam quality being greater than a fifth threshold.

[0116] In some embodiments, the current beam may also be referred to as the serving beam.

[0117] In some embodiments, the new beam may also be referred to as a candidate beam or a target beam, etc.

[0118] In some embodiments, a beam can be referred to as quasi-colocation (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.

[0119] In other words, the quality of at least one of the current beam and the new beam can be used to assess whether an event is met, thereby triggering a report.

[0120] In some embodiments, the quality of a beam can be a measurement of a reference signal resource. For example, the quality of the current beam can be a measurement of the reference signal resource corresponding to the current beam. As another example, the quality of a new beam can be a measurement of the reference signal resource corresponding to a candidate beam. Here, the measurement of the reference signal resource can be understood as a measurement obtained by measuring the reference signal on the reference signal resource. For example, the measurement can be the layer 1 reference signal receiving power (L1-RSRP), the layer 1 signal-to-interference plus noise ratio (L1-SINR), etc., but is not limited to these.

[0121] In some embodiments, the reference signal resource corresponding to the new beam can be determined based on the configuration information of the reference signal resource set transmitted by the network device. For example, the reference signal resource corresponding to the new beam can be at least one reference signal resource in the reference signal resource set.

[0122] In some embodiments, the reference signal resource (or reference signal corresponding to the current beam) can be determined based on the indicated transmission configuration indication state (indicated TCIstate), or it can be determined based on the indicated TCIstate and the reference signal resource set, which is determined based on the configuration information of the reference signal resource set sent by the network device.

[0123] Optionally, the reference signal resource corresponding to the current beam is determined based on the indicated TCI state, and the reference signal is the CSI-RS corresponding to the quasi-co-location type (QCL Type) D in the indicated TCI state.

[0124] Optionally, the reference signal resource corresponding to the current beam is determined based on the indicated TCI state. The reference signal is the SSB that has a QCL relationship with the CSI-RS. The CSI-RS is the CSI-RS corresponding to the quasi-co-location type (QCL Type) D in the indicated TCI state.

[0125] Optionally, the reference signal resource corresponding to the current beam is determined based on the indicated TCI state and the reference signal resource set. When the resources included in the reference signal resource set are CSI-RS resources, the reference signal resource corresponding to the current beam is a CSI-RS resource, and the reference signal corresponding to the current beam is the CSI-RS corresponding to the quasi-co-address type (QCLType) D in the indicated TCI state.

[0126] Optionally, the reference signal resource corresponding to the current beam is determined based on the indicated TCI state and the reference signal resource set. When the reference signal resource set contains SSB resources, the reference signal resource corresponding to the current beam is an SSB resource, the reference signal corresponding to the current beam is an SSB, and the SSB has a QCL relationship with the CSI-RS corresponding to the quasi-co-address type (QCL Type) D in the indicated TCI state.

[0127] In step S2102, terminal 101 sends second information to network device 102.

[0128] In some embodiments, network device 102 receives second information sent by terminal 101.

[0129] In some embodiments, the second information is used to request a DG PUSCH, or to instruct the terminal to send a report on a Type 1CG PUSCH following the PUCCH. Optionally, the second information may be used to instruct the terminal to send the report on a Type 1CG PUSCH following X time-domain units of the PUCCH, where X is a positive integer. The time-domain unit can be a symbol, a time slot, a millisecond (ms), etc., and this disclosure does not limit this. The value of X can be determined by the terminal, which can report the value of X to the network device. Alternatively, the terminal may report the value of X, or the network device may configure the value of X to the terminal. The value of X can also be agreed upon in a protocol, and the terminal and / or network device can determine the value of X from the protocol.

[0130] For example, if the quality of the current beam and / or the new beam meets the event, the terminal can send second information to the network device on the PUCCH. The network device, upon receiving the second information, can schedule a DG PUSCH for the terminal or determine that the terminal will send a report on a Type 1CG PUSCH X time-domain units later. The terminal can send the report on the DG PUSCH scheduled for it by the network device, or it can send the report on a Type 1CG PUSCH X time-domain units later. Correspondingly, the network device can receive the report on the DG PUSCH scheduled for it, or it can receive the report on a Type 1CG PUSCH X time-domain units later.

[0131] For example, if the network device configures a first mode for the terminal (e.g., mode A in the above embodiment), after receiving the second information, the network device will schedule DG PUSCH resources for the terminal and trigger an event-triggered report in the DCI that schedules the DG PUSCH. The terminal will then send a report on the DG PUSCH, and the network device will receive the report on the DG PUSCH.

[0132] For example, if the network device configures a second mode for the terminal (e.g., mode B in the above embodiment), the network device will pre-configure a Type 1CG PUSCH for the terminal. This Type 1CG PUSCH is associated with the PUCCH used to send the second information. After the terminal sends the second information on the PUCCH, it sends a report on the Type 1CGPUSCH following the second information, and the network device receives the report on the Type 1CG PUSCH. It is understood that the Type 1CGPUSCH includes periodic PUSCH resources, and the PUCCH used to send the second information also includes periodic resources. Therefore, after the terminal sends the second information on a certain periodic PUCCH, it can select the first PUSCH resource after X time-domain units following the PUCCH to send the report. These X time-domain units are used for the report the terminal prepares to send on the PUSCH.

[0133] In some embodiments, the event is that the quality of the current beam is below a first threshold. The terminal may send a report if at least one of the following conditions is met: the measurement value of the current beam satisfies the event M times; or the measurement value of the current beam satisfies the event M times or more within a time window determined by the terminal, where M is a positive integer. Since the terminal may send second information on the PUCCH before sending the report, i.e. before the PUSCH, the terminal may also send second information if at least one of the following conditions is met: the measurement value of the current beam satisfies the event M times; or the measurement value of the current beam satisfies the event M times or more within a time window determined by the terminal, where M is a positive integer.

[0134] Optionally, a second message can be sent on the PUCCH if the measurement value of the current beam satisfies the event M times. Here, M is a positive integer. For example, if M is 1, then the second message can be sent on the PUCCH as long as the measurement value of the current beam satisfies the event once. Alternatively, if M is an integer greater than 1, then the second message is not sent on the PUCCH if the measurement value of the current beam satisfies the event once, but only if the measurement value of the current beam cumulatively satisfies the event M times. The M times can be consecutive M times or non-consecutive M times. For example, non-consecutive M times can be understood as M times satisfying the event and (NM) times not satisfying the event in N consecutive measurements, with these (NM) times distributed among the M measurements. M is a positive integer, and M is less than N.

[0135] For example, assuming M is 3, if an event is satisfied in each of the three consecutive measurements within a time window, it can be considered as M consecutive satisfied events.

[0136] For example, assuming M is 3 and N is 4, if the first two and fourth measurements satisfy the event, but the third measurement does not satisfy the event, then it can be considered as a non-continuous M-times satisfying event.

[0137] Optionally, a second message may be sent on the PUCCH if the number of times the measurement value of the current beam satisfies the event is greater than or equal to M within a time window determined by the terminal. Here, M is a positive integer. It is understood that, in the above optional example, if M is an integer greater than 1, but the interval between the first and Mth satisfying events of the current beam's measurement value is too long, then the previous evaluations may be unreliable, and sending the second message on the PUCCH in this case is also inappropriate. Therefore, in this optional example, a time window can be defined, and the second message is sent on the PUCCH if the number of times the measurement value of the current beam satisfies the event is greater than or equal to M within the time window, thereby making the evaluation more reliable. Here, M times can be consecutive M times or non-consecutive M times within the time window. Examples of consecutive M times and non-consecutive M times can be found in the above embodiments, and will not be repeated here.

[0138] In some embodiments, the terminal may determine a time window so that if the number of times the measurement value of the current beam satisfies the event is greater than or equal to M within the time window determined by the terminal, the second information is sent on the PUCCH.

[0139] It is understandable that a terminal may send the second information if at least one of the following conditions is met: the current beam's measurement value satisfies the event M times; or the current beam's measurement value satisfies the event M times or more within a time window determined by the terminal. Alternatively, the terminal may send the second information directly without checking if the above conditions are met. For example, the terminal may send the second information on the PUCCH, check if the above conditions are met between the PUCCH and PUSCH, and send a report on the PUSCH if at least one of the above conditions is met; otherwise, it may not send a report.

[0140] In some embodiments, the second information is Beam Report Indicator (BRI) information, but it is not limited thereto. This disclosure does not limit the name of the second information.

[0141] In step S2103, network device 102 sends first information to terminal 101.

[0142] In some embodiments, terminal 101 receives first information sent by network device 102.

[0143] In some embodiments, the report is triggered by an event, namely, the current beam quality falling below a first threshold. The report may include a first differential quality, which is the difference between the current beam quality and the first threshold. The inclusion of the first differential quality in the report may be indicated by the network device. For example, if the network device sends first information indicating that the first differential quality should be reported, the report will include the first differential quality. If the network device does not send first information, or if the first information indicates that the first differential quality should not be reported, the report may not include the first differential quality. The first information can be understood as enabling the reporting of the first differential quality.

[0144] For example, the first threshold value could be -100 dBm, and if the current beam quality is -105 dBm, the first differential quality would be 5 dB. Of course, the specific values ​​above are exemplary and this disclosure does not limit them.

[0145] It is understood that step S2103 is optional. The terminal may include the first score quality in the report by default without requiring network device indication, in which case step S2103 can be omitted.

[0146] In step S2104, terminal 101 sends a report to network device 102.

[0147] In some embodiments, network device 102 receives a report sent by terminal 101.

[0148] In some embodiments, the terminal sends a report if at least one of the following conditions is met: the number of times the measurement value of the current beam satisfies the event is M; or the number of times the measurement value of the current beam satisfies the event is greater than or equal to M within a time window determined by the terminal, where M is a positive integer. For details, please refer to the embodiment of step S2102 above, which will not be repeated here.

[0149] In some embodiments, the report may be carried by a PUSCH, for example, on a DG PUSCH or a Type 1 CGPUSCH. Specific details can be found in the embodiments of step S2102 described above, and will not be repeated here.

[0150] In some embodiments, the report also includes at least one of the following:

[0151] The quality of the first reference signal resource in the reference signal resource set;

[0152] Identification of the first reference signal resource;

[0153] The second differential quality is the difference between the quality of the second reference signal resource and the quality of the first reference signal resource in the reference signal resource set.

[0154] Identification of the second reference signal resource.

[0155] Optionally, the report may also include the quality of the first reference resource in the set of reference signal resources. The first reference signal resource can be understood as any one or more reference signal resources, for which the actual quality can be reported. Here, actual quality can also be understood as absolute quality, rather than relative quality. The first reference signal resource is the reference signal resource corresponding to the first new beam.

[0156] For example, the measured value of the reference signal on the first reference signal resource (assumed to be RS#1) is -98 dBm, and the measured value of the reference signal on the second reference signal resource (assumed to be RS#2) is -101 dBm. Both -98 dBm and -101 dBm are actual quality (absolute quality). For the first reference signal resource, its actual quality, i.e., -98 dBm, can be included in the report. For example, for a relatively high-quality reference signal resource, its actual quality can be included in the report; for a relatively low-quality reference signal resource, its relative quality can be included in the report. In the embodiments of this disclosure, because the beam quality of the first reference signal resource is relatively high, its actual quality can be reported.

[0157] Optionally, the report may also include the identifier of the first reference resource in the set of reference signal resources. For example, if the first reference signal resource is a CSI-RS resource, the identifier of the first reference signal resource may be the identifier of the CSI-RS resource. As another example, if the first reference signal resource is an SSB resource, the identifier of the first reference signal resource may be the identifier of the SSB resource.

[0158] Optionally, the report may also include a second differential quality, which is the difference between the quality of the second reference signal resource and the quality of the first reference signal resource in the reference signal resource set. The second reference signal resource can be understood as any one or more reference signal resources, for which their relative quality can be reported. The second reference signal resource is the reference signal resource corresponding to the second new beam.

[0159] For example, the measured value of the reference signal (assumed to be RS#1) on the first reference signal resource is -98 dBm, and the measured value of the reference signal (assumed to be RS#2) on the second reference signal resource is -101 dBm. Both -98 dBm and -101 dBm are actual quality (absolute quality). For the second reference signal resource, its relative quality can be reported, using the actual quality of the first reference signal resource as the reference quality. The relative quality can be the difference between the actual quality of the first and second reference signal resources. For example, 3 dB can be reported, where 3 dB is the difference between -101 dBm and -98 dBm. For example, for a relatively high-quality reference signal resource, the report can include its actual quality; for a relatively low-quality reference signal resource, the report can include its relative quality. In the embodiments of this disclosure, because the beam quality of the second reference signal resource is relatively low, its relative quality can be reported, i.e., the second differential quality can be reported.

[0160] It is understood that, in the embodiments of this disclosure, the quality of the first reference signal resource refers to the actual quality of the first reference resource, the quality of the second reference signal resource refers to the actual quality of the second reference signal resource, the first differential quality refers to the relative quality corresponding to the current beam, and the second differential quality refers to the relative quality corresponding to the second reference signal resource. Specifically, the first differential quality is the difference between the quality of the current beam and a first threshold, meaning the reference value for the first differential quality is the first threshold value; while the second differential quality is the difference between the quality of the second reference signal resource and the quality of the first reference signal resource, meaning the reference value for the second differential quality is the quality of the first reference signal resource. That is, the reference values ​​corresponding to the two differential values ​​in the report triggered by Event1 are different. The differential quality (or differential value) may include, but is not limited to, differential L1-RSRP or differential L1-SINR.

[0161] Optionally, the report may also include an identifier for the second reference signal resource. For example, if the second reference signal resource is a CSI-RS resource, the identifier for the second reference signal resource may be the identifier for the CSI-RS resource. As another example, if the second reference signal resource is an SSB resource, the identifier for the second reference signal resource may be the identifier for the SSB resource.

[0162] In some embodiments, the quality of the first reference signal resource, the first differential quality, and the second differential quality in the report can be bit values ​​corresponding to the quality of the first reference signal resource, the first differential quality, and the second differential quality, respectively. Taking the quality of the first reference signal resource as an example, assuming the quality range of the first reference signal resource is -140dBm to -44dBm, and the quantization interval can be 1dB, it can be indicated using 7 bits: 0000000 indicates -140dBm, 0000001 indicates -139dBm, and 0000010 indicates -138dBm. This disclosure does not provide further examples. For another example, if the quantization interval of the differential quality is 2dB, it can be indicated using 4 bits. If the first differential quality or the second differential quality is 0 to 1dB, it can be quantized as 0000; if the first differential quality or the second differential quality is 0 to 1dB, it can be quantized as 0001; if the first differential quality or the second differential quality is 3 to 5dB, it can be quantized as 0010. This disclosure does not provide further examples. Of course, the specific values ​​mentioned above are merely examples, and this disclosure does not limit them.

[0163] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2104. The order of implementation is not limited. For example, step S2104 may be implemented as a standalone embodiment, but is not limited thereto. For example, step S2101 may be omitted. For example, the network device may send the first information first and then the second information, or it may send the second information first and then the first information, or it may send the first and second information simultaneously. That is, step S2102 may be implemented before step S2103, or it may be implemented after step S2103, or it may be implemented together, but is not limited thereto.

[0164] In some embodiments, steps S2102 to S2104 are optional and may be omitted or substituted in different embodiments.

[0214] Figure 5 is a schematic diagram illustrating a communication method according to an embodiment of the present disclosure. As shown in Figure 5, this embodiment of the present disclosure relates to a communication method, which includes:

[0215] In step S5101, terminal 101 sends a report to network device 102.

[0216] In some embodiments, the above methods may include the methods of the embodiments related to the communication system 100, terminal 101, and network device 102, which will not be described again here.

[0217] This disclosure provides a method for reusing the beam report format corresponding to Event 2 for Event 1 in an event-triggered beam report, as follows:

[0218] In some embodiments, the terminal sends a first report, which corresponds to a report triggered by a first event. The condition for the first event is that the quality of the current beam is lower than a first threshold. The first report includes the first differential quality corresponding to the current beam, and the reference quality of the differential quality is the first threshold.

[0219] In some embodiments, the beam quality is L1-RSRP or L1-SINR.

[0220] In some embodiments, the reference quality is an actual value, such as a first threshold of -100dBm, i.e., the reference quality is -100dBm. If the quality of the current beam is -105dBm, then the differential quality of the current beam is 5dBm, which is the difference between the quality of the current beam (-105dBm) and the reference quality (-100dBm).

[0221] In some embodiments, the terminal receives configuration information for a first reference signal resource set, and the first report includes the RS ID and quality of at least one reference signal resource in the first reference signal resource set.

[0222] In some embodiments, the RS ID of the reference signal resource may include an SSB ID or a CSI-RS ID.

[0223] In some embodiments, the quality of at least one reference signal resource includes at least one of a first quality and a second differential quality, wherein the reference quality of the second differential quality is the first quality.

[0224] In some embodiments, the L1-RSRP of RS#1 in the new beam is -98dBm and that of RS#2 is -101dBm. Therefore, the RSID corresponding to the strongest L1-RSRP, -98dBm, is RS#1. Thus, the L1-RSRP of RSID#1 is the reported actual L1-RSRP value (i.e., the first quality), which is -98dBm. The L1-RSRP of RS#2 is the differential L1-RSRP, which is the difference between -101dBm and -98dBm, i.e., 3dB.

[0225] In some embodiments, both the actual L1-RSRP and the differential L1-RSRP may need to be quantized.

[0226] For example, the actual L1-RSRP range is -140dBm to -44dBm, with a quantization interval of 1dB. It uses 7 bits for indication: 0000000 indicates -140dBm, 0000001 indicates -139dBm, 0000010 indicates -138dBm, and so on.

[0227] For example, the quantization interval of differential L1-RSRP is 2dB. For example, a 4-bit indicator can be used, such as 0000 indicating 0dB, 0001 indicating 2dB, 0010 indicating 4dB, and so on.

[0228] In some embodiments, the terminal receives first information, which is used to enable reporting of the quality of the current beam.

[0229] In some embodiments, the terminal determines a first window, within which the number of times the current beam quality is lower than a first threshold is greater than or equal to M, where M is greater than or equal to 1.M is based on network configuration or protocol agreement.

[0230] In some embodiments, the terminal sends a first report on the PUSCH, which is either the PUSCH scheduled by the base station DCI or the PUSCH of Type 1CG.

[0231] In some embodiments, before sending the first report, the terminal sends first information on the PUCCH. The first information is used to request the base station to schedule PUSCH resources or to indicate that the terminal is about to send the first report.

[0232] In some embodiments, the RS corresponding to the current beam is determined based on at least one of the indicated TCI state and the first set of reference signal resources.

[0233] In some embodiments, the RS corresponding to the CSI-RS resource corresponding to QCL Type D in the Indicated TCI state is the RS corresponding to the current beam, or the SSB of the QCL Type D source of the CSI-RS is the RS corresponding to the current beam.

[0234] In some embodiments, when the resources included in the first reference signal resource set are CSI-RS resources, the RS corresponding to the current beam is a CSI-RS; when the resources included in the first reference signal resource set are SSB resources, the RS corresponding to the current beam is an SSB.
