[0080] In some embodiments, the acquisition of data, information, etc., may comply with the laws and regulations of the country where the location is situated.

[0081] In some embodiments, data, information, etc., may be obtained with the user's consent.

[0082] 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.

[0083] Currently, the considerations are for base station configurations that provide periodic, semi-persistent, or non-periodic beam measurement reports.

[0084] 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.

[0085] In some embodiments, beam measurement reports can be triggered based on an event. Events include, but are not limited to, any of the following: Event 1: The current beam quality is below a threshold; Event 2: The beam quality of the new beam is higher than the current beam by one threshold; Event 3: The current beam quality is below one threshold, and the new beam quality is above another threshold; Event 4: The beam quality of the new beam is above a threshold; Event 5: The beam quality of the new beam is higher than that of an active beam by a threshold.

[0086] 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.

[0087] The threshold values ​​for each of the above events can be the same or different.

[0088] 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.

[0089] 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 number of symbols (mode B).

[0090] For mode A, where the information is PUCCH and PUSCH is dynamically scheduled by the base station, the time interval between PUCCH and PUSCH is determined by the base station's scheduling. If the time interval is long, even if the terminal assesses the beam quality of a new beam and / or the current beam M times before the PUCCH, satisfying the triggering condition of an event, the beam quality of that new beam and / or current beam may change between the PUCCH and PUSCH, causing the event triggering condition to not be met. Therefore, determining the content of the report ultimately submitted by the terminal on the PUSCH is a problem that needs to be solved.

[0091] For mode B, the first piece of information is the PUCCH, and the PUSCH is a semi-persistently allocated PUSCH. The base station can pre-configure the time interval between the PUCCH and PUSCH. Of course, if the time interval between the two is long, the same problem exists in mode A.

[0092] Therefore, this disclosure provides a communication method in which the terminal determines a first time, and the first time is used to determine that the reference signal resource corresponding to the report is a reference signal resource no later than the first time. The report is triggered by an event and carried based on PUSCH. In other words, by determining the first time, it is possible to determine which part of the reference signal resource the content in the report is based on, i.e., based on the reference signal resource no later than the first time. This makes the reported reports more reliable and improves communication efficiency.

[0104] Figure 2 This is a schematic diagram illustrating a communication method interaction according to an embodiment of this disclosure. Figure 2 As shown, this disclosure relates to a communication method for a communication system 100, the method comprising: In step S2101, network device 102 sends first information to terminal 101.

[0105] In some embodiments, terminal 101 receives first information sent by network device 102.

[0106] In some embodiments, the first information is used to determine a first time, the first time is used to determine that the reference signal resource corresponding to the report is a reference signal resource no later than the first time, the report is triggered by an event, and the report is based on PUSCH bearer.

[0107] In some embodiments, reports triggered by events can be carried by a PUSCH. For example, they can be carried by a DGPUSCH, or by a Type 1 CG PUSCH. Before the PUSCH, the terminal can send second information on the Physical Uplink Control Channel (PUCCH) to request the DGPUSCH, or to indicate that the terminal will send the report on a Type 1 CG PUSCH after the PUCCH.

[0108] Optionally, the second information can be used to instruct the terminal to send the report on a Type 1 CGPUSCH after 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. The value of X can also be determined by the network device, which can configure the value of X to the terminal. The value of X can also be agreed upon in the protocol, and the terminal and / or the network device can determine the value of X from the protocol.

[0109] For example, if the beam 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 1 CG PUSCH X time units later. The terminal can send a report on the DGPUSCH scheduled by the network device for the terminal, or it can send a report on a Type 1 CG PUSCH X time units later.

[0110] 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.

[0111] 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 configure a Type 1 CG PUSCH for the terminal in advance. This Type 1 CG 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 1 CGPUSCH following the second information. The network device will receive the report on the Type 1 CG PUSCH. Since the terminal triggers the transmission of the second information on the PUCCH based on the measurement value of the reference signal resources preceding the PUCCH, the reference signal resources corresponding to the report can be the reference signal resources preceding the PUCCH.

[0112] However, between PUCCH and PUSCH, the beam quality of the current beam and / or new beam that satisfies the event before PUCCH may change, for example, becoming unable to satisfy the event, or the beam quality of other new beams may satisfy the event.

[0113] It is understood that the report can be a beamform report, a CSI report, etc., and this disclosure does not limit it. The report may include the identifier of the reference signal resource, the measurement value corresponding to the reference signal resource (measuring the reference signal on the reference signal resource can obtain the measurement value corresponding to the reference signal resource, for example, the measurement value may 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).

[0114] In other words, the content of the report is based on reference signal resources. However, whether the reference signal resources corresponding to the report are reference signal resources before PUCCH, or reference signal resources between PUCCH and PUSCH, or reference signal resources within a certain time point or time window, are technical issues that need to be resolved.

[0115] In this embodiment of the disclosure, by determining the first time, the reference signal resource in the report can be determined to be a reference signal resource no later than the first time, thereby solving the above-mentioned problem.

[0116] It is understandable that reference signal resources include the time domain resources and frequency domain resources of the reference signal. The reference signal resources are no later than the first time, which can be understood as the time domain resources of the reference signal being no later than the first time.

[0117] In some embodiments, the reference signal resources include the reference signal resources corresponding to the current beam and / or the reference signal resources corresponding to the new beam.

[0118] In some embodiments, the reference signal resources corresponding to the new beam can be determined based on configuration information of a set of reference signal resources sent by the network device. For example, the network device sends configuration information of a set of reference signal resources to the terminal, which corresponds to the set of reference signal resources corresponding to the new beam. The reference signal resources corresponding to the new beam can be at least one reference signal resource in that set. The report may include reference signal resources corresponding to the new beam no later than a first time, and these reference signal resources can be determined from the reference signal resources corresponding to the new beam.

[0119] 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 (TCI) state, or it can be determined based on the indicated TCI state 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] 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, and the reference signal corresponding to the current beam is an SSB that has a QCL relationship with the CSI-RS corresponding to the quasi-co-address type (QCL Type) D in the indicated TCI state.

[0124] In some embodiments, the report may include reference signal resources corresponding to the current beam no later than a first time, and the reference signal resources corresponding to the current beam no later than the first time may be determined from the reference signal resources corresponding to the current beam.

[0125] In some embodiments, the activated beam can be determined based on the activated TCI state, and the method for determining it is the same as the method for obtaining the current beam based on the indicated TCI state, which will not be described again here.

[0126] In some embodiments, the current beam may also be referred to as the serving beam.

[0127] In some embodiments, the new beam may also be referred to as a candidate beam or a target beam, etc.

[0128] In some embodiments, the 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.

[0129] In some embodiments, the first information is used to indicate at least one of the following: the time-domain location of the PUCCH; the time-domain location of the PUSCH; and parameters of the Channel State Information Reference Resource (CSI reference resource).

[0130] Optionally, the first information can be used to indicate the time-domain location of the PUCCH. The time-domain location of the PUCCH can be any symbol of the PUCCH or the time slot in which the PUCCH is located. For example, the terminal can determine a first time based on the time-domain location of the PUCCH. For example, the first time can be the time-domain location of the PUCCH or a time before the PUCCH; that is, the reference signal resource corresponding to the report can be a reference signal resource no later than the time-domain location of the PUCCH, or it can be a reference signal resource at a time no later than the time before the PUCCH. For example, the report sent by the terminal to the network device includes the identifier of the reference signal resource no later than the time-domain location of the PUCCH, and / or the measurement value corresponding to the corresponding reference signal resource. Another example is that the report sent by the terminal to the network device includes the identifier of the reference signal resource no later than a time before the PUCCH, and / or the measurement value corresponding to the corresponding reference signal resource. Here, "no later than" includes "earlier than" and "simultaneously." For example, the time-domain location no later than the PUCCH can be an earlier time-domain location or a time-domain location simultaneous with the PUCCH. This disclosure does not provide examples of each instance. The term "first time" can refer to a specific point in time or a time window. For instance, the first time can be a symbol or a time slot; this disclosure does not limit its scope.

[0131] Optionally, the first information is used to indicate the time-domain location of the PUSCH. The time-domain location of the PUSCH can be any symbol of the PUSCH, or the time slot in which the PUSCH is located. For example, the terminal can determine a first time based on the time-domain location of the PUSCH. For example, the first time can be the time-domain location of the PUSCH or a time before the PUSCH; that is, the reference signal resource corresponding to the report can be a reference signal resource no later than the time-domain location of the PUSCH, or it can be a reference signal resource at a time no later than the PUSCH. For example, the report sent by the terminal to the network device includes the identifier of the reference signal resource no later than the time-domain location of the PUSCH, and / or the measurement value corresponding to the corresponding reference signal resource. As another example, the report sent by the terminal to the network device includes the identifier of the reference signal resource at a time before the PUSCH, and / or the measurement value corresponding to the corresponding reference signal resource. Here, "no later than" includes "earlier than" and "simultaneously." For example, the time-domain location no later than the PUSCH can be an earlier time-domain location or a time-domain location simultaneous with the PUSCH. This disclosure does not provide examples of each instance. The "first time" can be a point in time or a time window. For example, the first time can be a symbol or a time slot. Optionally, the reference signal resources preceding the PUSCH can include reference signal resources between the PUCCH and PUSCH, or can include reference signal resources between the PUCCH and PUSCH as well as reference signal resources preceding the PUCCH. That is, the reference signal resources preceding the PUSCH can be partly before the PUCCH and partly between the PUCCH and PUSCH; this disclosure does not limit this.

[0132] Optionally, the first information is used to indicate the parameters of the CSI reference resource. The parameters of the CSI reference resource can be used to determine the time-domain location of the CSI reference resource, and the first time can be the time-domain location of the CSI reference resource. The time-domain location of the CSI reference resource can be the slot in which the CSI reference resource is located, or any symbol within the slot in which the CSI reference resource is located. For example, the parameters of the CSI reference resource include at least one of the following: a first offset value, configured by the network device; a second offset value, which is a carrier aggregation slot offset value; and subcarrier spacing. The time-domain location of the CSI reference resource is determined based on the following formula 1.

[0133] Formula 1 In Formula 1, ,in, For downlink subcarrier spacing, For uplink subcarrier spacing, and It is configured by the higher-layer signaling parameter (configuredca-SlotOffset). n' is the uplink slot of the PUSCH corresponding to sending the CSI report. UL indicates uplink, and DL indicates downlink.

[0134] In some embodiments, for periodic and semi-permanent CSI reporting, if only one CSI-RS / SSBresource is configured for channel measurement, n CSI_ref Greater than or equal to The minimum value is determined as long as the determined time is a valid downlink time slot. If multiple CSI-RS / SSB resources are configured for channel measurement, n CSI_ref Greater than or equal to The minimum value is determined as long as the determined time is a valid downlink time slot.

[0135] In some embodiments, for non-periodic CSI reporting, if the UE is instructed by the DCI to trigger a CSI report in the same time slot as the DCI, n CSI_ref That is, the time slot corresponding to DCI, otherwise n CSI_ref greater than or equal to The minimum value, as long as n - n CSI_ref This represents a valid downlink time slot. Z' is the delay requirement value calculated by CSI. It is a time-domain unit.

[0136] In some embodiments, K offset This is the first offset value, configured by the network device. For example, ,in, K cell,offset Indicated by a cell-specific offset value, K UE,offset Instructed by the Differential Timing Advance Offset Media Access Control Unit (Differential Koffset MAC CE command). If no instruction is given, then... K cell,offset or K UE,offset It can be zero.

[0137] It is understood that the above optional embodiments can be implemented individually or in combination. For example, the first information may only indicate the time domain position of the PUCCH, in which case the terminal can determine the first time based on the time domain position of the PUCCH. Alternatively, the first information may indicate both the time domain position of the PUCCH and the time domain position of the PUSCH, while whether the terminal determines the first time based on the time domain position of the PUCCH or the time domain position of the PUSCH is determined by other methods.

[0138] In some embodiments, the name of the first information is not limited in this disclosure, and it may be, for example, "instruction information", "configuration information", etc.

[0139] In step S2102, terminal 101 determines the first time.

[0140] In some embodiments, the first time includes at least one of the following: the time-domain location of the PUCCH or the time before the PUCCH; the time-domain location of the PUSCH or the time before the PUSCH; and the time-domain location of the channel state information reference resource.

[0141] In some embodiments, the terminal can determine a first time based on first information. For example, the first time can be determined as the time domain location of the PUCCH or a time prior to the PUCCH, based on the time domain location of the PUSCH indicated by the first information. As another example, the first time can be determined as the time domain location of the PUSCH or a time prior to the PUSCH, based on the time domain location of the PUSCH indicated by the first information. Yet another example, the CSI reference resource can be determined based on the parameters of the CSI reference resource indicated by the first information, and the first time can be determined as the time domain location of the CSI reference resource.

[0142] In some embodiments, the terminal may also determine the first time based on other methods. For example, the network device may pre-configure at least one of the parameters of the PUCCH time domain location, the PUSCH time domain location, and the CSI reference resource, and the terminal may determine the first time based on the pre-configured at least one of the above parameters.

[0143] In some embodiments, the first time is the time prior to the PUCCH, and the first time is at least separated from the time domain position of the PUCCH by a second time. For example, the second time can be the processing time. For example, the second time is the processing time required to generate Uplink Control Information (UCI) on the PUCCH, which is used to carry second information, which may be called a beam reporting indication.

[0144] In some embodiments, the first time is the time prior to PUSCH, and there is at least a third time interval between the first time and PUSCH. For example, the third time can be the processing time. For example, the third time is the processing time required to generate the report on PUSCH.

[0145] It is understandable that the second and third times can be the same or different, and this disclosure does not limit this.

[0146] In some embodiments, the terminal determines the first time by: the terminal determining the first time based on the interval between PUCCH and PUSCH.

[0147] Optionally, if the interval between PUCCH and PUSCH is greater than a first threshold, the first time can be the time before PUSCH. For example, if the interval between PUCCH and PUSCH is greater than the first threshold, there may be a significant change in the quality of the current beam and / or a new beam between PUCCH and PUSCH, such as the beam quality becoming unsatisfactory, or the beam quality of another new beam satisfying the requirement. Therefore, the first time can be determined as the time before PUSCH. That is, the measurement value satisfaction event corresponding to the reference signal resource can be determined before PUSCH, and a report can be sent to the network device. The report includes the identifier and / or measurement value corresponding to the reference signal resource before PUSCH. The time before PUSCH can be the time between PUCCH and PUSCH, or it can be the time between PUCCH and PUSCH and the time before PUCCH. For details, please refer to the other embodiments described above, which will not be repeated here.

[0148] It is understood that the reference signal resource can be the reference signal resource corresponding to the current beam and / or the new beam, and the measurement value satisfaction event corresponding to the reference signal resource can be understood as the quality satisfaction event of the current beam and / or the new beam. That is to say, the beam quality includes L1-RSRP or L1-SINR, but is not limited to these.

[0149] Optionally, the measurement value satisfaction event corresponding to the reference signal resource can be a measurement value satisfaction event of the reference signal resource, that is, a measurement value satisfaction event corresponding to the current beam and / or the new beam.

[0150] Optionally, the event where the measurement value of the reference signal resource satisfies the requirement can be an event where M measurements of the reference signal resource satisfy the requirement within a time window no later than the first time, where M is a positive integer. For example, M can be 1, and the event where the measurement value of the reference signal resource satisfies the requirement for 1 measurement within a time window no later than the first time. Alternatively, M can be greater than 1, and the event where two or more measurements of the reference signal resource satisfy the requirement. The M measurements can be consecutive M measurements or non-consecutive M measurements within the time window. For example, non-consecutive M measurements can be understood as M measurements satisfying the requirement and (NM) measurements not satisfying the requirement in N consecutive measurements, with these (NM) measurements distributed among the M measurements. M is a positive integer, and M is less than N.

[0151] 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.

[0152] 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.

[0153] Optionally, if the interval between PUCCH and PUSCH is less than a first threshold, the first time can be the time before PUCCH. For example, if the interval between PUCCH and PUSCH is less than the first threshold, it is possible that there is no significant change in the quality of the current beam and / or the new beam between PUCCH and PUSCH, or in other words, the probability of a significant change in the quality of the current beam and / or the new beam between PUCCH and PUSCH is low. A significant change in the quality of the current beam and / or the new beam could be an event where the quality becomes unsatisfactory, or an event where the quality of another new beam satisfies the requirement. Therefore, the first time can be determined as the time before PUCCH.

[0154] Optionally, if the interval between PUCCH and PUSCH is equal to the first threshold value, the first time can be the time before PUSCH or the time before PUCCH.

[0155] In some embodiments, the first threshold value is configured in the network device or predefined in the protocol. This disclosure does not limit the size of the first threshold value.

[0156] In some embodiments, the event includes at least one of the following: The beam quality of the current beam is below the second threshold. The beam quality of the new beam is higher than that of the current beam, and the difference between the beam quality of the new beam and the beam quality of the current beam is greater than the third threshold. The beam quality of the new beam is higher than the fourth threshold. The beam quality of the new beam is higher than that of the active beam, and the difference between the beam quality of the new beam and the active beam is greater than the fifth threshold.

[0157] For example, an event could include the current beam quality being below a second threshold. Event 1 is the current beam quality being below the second threshold.

[0158] For example, an event could include a new beam having a higher beam quality than the current beam, and the difference between the beam quality of the new beam and the current beam being greater than a third threshold. Event 2 is defined as a new beam having a higher beam quality than the current beam, and the difference between the beam quality of the new beam and the current beam being greater than a third threshold.

[0159] 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.

[0160] 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.

[0161] 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.

[0162] Taking Event 1 as an example, the event can be either a single measurement value of the current beam being greater than the second threshold value, or M measurements of the current beam within a time window no later than the first time being all greater than the second threshold value. This disclosure does not provide examples of each of these scenarios.

[0163] In some embodiments, the first threshold values ​​to the fifth threshold values ​​may be the same or different.

[0164] In step S2103, terminal 101 sends second information to network device 102.

[0165] In some embodiments, network device 102 receives second information sent by terminal 101.

[0166] In some embodiments, the second information is sent based on PUCCH format 0 or format 1.

[0167] In some embodiments, the second information is used to request a DG PUSCH, or to instruct the terminal to send the report on a Type 1 CG PUSCH following the PUCCH. Optionally, the second information may be used to instruct the terminal to send the report on a Type 1 CG PUSCH following X time-domain units of the PUCCH, where X is a positive integer. The time-domain unit may be a symbol, a time slot, a millisecond (ms), etc., and this disclosure does not limit this. The value of X may be determined by the terminal, which may report the value of X to the network device. The value of X may also be determined by the network device, which may configure the value of X to the terminal. The value of X may also be agreed upon in the protocol, and the terminal and / or the network device may determine the value of X from the protocol.

[0168] For example, if the beam 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 1 CG PUSCH after X time units. The terminal can send a report on the DGPUSCH scheduled for the terminal by the network device, or on a Type 1 CG PUSCH after X time units. Correspondingly, the network device can receive the report on the DG PUSCH scheduled for the terminal, or on a Type 1 CGPUSCH after X time units.

[0169] 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.

[0170] 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 1 CG PUSCH for the terminal. This Type 1 CG 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 1 CGPUSCH following the second information, and the network device receives the report on the Type 1 CG PUSCH. It is understood that the Type 1 CGPUSCH 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.

[0171] 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.

[0172] In step S2104, terminal 101 sends a report to network device 102.

[0173] In some embodiments, network device 102 receives a report sent by terminal 101.

[0174] In some embodiments, the terminal may send a report to the network device when a triggering condition is met. For example, the terminal may send a report to the network device via a PUSCH. For instance, the terminal may send a report on a DG PUSCH scheduled by the network device, or it may send a report on a Type 1 CG PUSCH.

[0175] In some embodiments, the report includes at least one of the following: L1-RSRP; L1-SINR; SSB identifier (ID); CSI-RS identification; Activate beam identifier; The third information is used to indicate whether the measured value of the reference signal corresponding to the current beam and / or the new beam meets the conditions for triggering the event.

[0176] Optionally, the report may include L1-RSRP. For example, it may include the L1-RSRP corresponding to the current beam. Or, for example, it may include the L1-RSRP corresponding to the new beam. The L1-RSRP can be corresponding to the current beam, the new beam, or the active beam; this disclosure does not limit this. The L1-RSRP can be an actual value or a differential value. That is, the L1-RSRP can be the actual L1-RSRP or a differential L1-RSRP. The actual value can be understood as an absolute value, and the differential value as a relative value. For example, L1-RSRP #1 can be -98 dBm, and L1-RSRP #2 can be 101 dBm, etc., which are actual values. L1-RSRP #2 can also be 3 dBm, which is a differential value, representing the difference between L1-RSRP #2 and L1-RSRP #1. In this case, L1-RSRP #1 serves as the reference L1-RSRP for L1-RSRP #2.

[0177] Optionally, the report may include L1-SINR. For example, it may include the L1-SINR corresponding to the current beam. Or, for example, it may include the L1-SINR corresponding to the new beam. The L1-SINR can be for the current beam, the new beam, or the active beam; this disclosure does not limit this. The L1-SINR can be an actual value or a differential value. That is, the L1-SINR can be the actual L1-SINR or a differential L1-SINR. The meaning of the differential value can be referred to the above optional examples, and will not be repeated here.

[0178] Optionally, the report may include an SSB identifier. For example, if the reference signal resource corresponding to the current beam and / or the new beam is an SSB resource, the report may include an SSB identifier. The SSB identifier may correspond to the current beam, the new beam, or the active beam; this disclosure does not limit this.

[0179] Optionally, the report may include a CSI-RS identifier. For example, if the reference signal resource corresponding to the current beam and / or the new beam is a CSI-RS resource, the report may include a CSI-RS identifier. The CSI-RS identifier may correspond to the current beam, the new beam, or the active beam; this disclosure does not limit this.

[0180] Optionally, the report may include an activated beam identifier. For example, if the event is that the beam quality of a new beam is higher than that of an activated beam, and the difference between the beam quality of the new beam and the activated beam is greater than a fifth threshold, the report may include the activated beam identifier corresponding to the activated beam. The activation identifier may be a number among multiple activated TCI states activated by the network device for the terminal. For example, if the network device activates 8 activated TCI states for the terminal, and the TCI state IDs from smallest to largest are TCI state ID#1, TCI state ID#2, TCI state ID#3, TCI state ID#7, TCI state ID#8, TCI state ID#9, TCI state ID#15, and TCI state ID#16.

Alternatively, the active beam identifier corresponding to TCI state ID#1 can be 00000001, the active beam identifier corresponding to TCI state ID#2 can be 00000010, the active beam identifier corresponding to TCI state ID#3 can be 00000100, the active beam identifier corresponding to TCI state ID#7 can be 00001000, the active beam identifier corresponding to TCI state ID#8 can be 00010000, the active beam identifier corresponding to TCI state ID#9 can be 00100000, the active beam identifier corresponding to TCI state ID#15 can be 01000000, and the active beam identifier corresponding to TCI state ID#16 can be 1000000. That is, each active beam corresponds to 1 bit. If the bit is displayed as the first value, it indicates that active beam. If the report needs to indicate multiple active beam identifiers, the bits corresponding to multiple active beams can be displayed as the first value. For example, if TCI state ID#1 and TCI state ID#2 are included, the active beam identifier would be 00000011. In this embodiment, the first value can be "1". The first value can also be "0", and the present invention does not impose any restrictions.
