[0042] Embodiments of the present disclosure provide a method of beam reporting, a communication device, a communication system, and a storage medium.

[0043] In a first aspect, embodiments of the present disclosure provide a method of beam reporting, performed by a terminal, the method comprising:

[0044] transmitting first information, the first information being used to indicate that the terminal will transmit a beam report;

[0045] receiving second information;

[0046] transmitting or not transmitting the beam report based on the second information.

[0047] In the above embodiments, when the terminal determines that at least one first condition for triggering sending of the beam report is met, the terminal sends first information to the network device to inform the network device that the terminal will send the beam report, then the network device sends second information to the terminal, the second information is used by the terminal to determine whether to send the beam report, and the terminal sends or does not send the beam report based on the second information. It can be seen that, in the method of the present disclosure, when the terminal informs the network device that the terminal will send the beam report, the network device returns a feedback information (i.e., the second information) to the terminal, so that the terminal determines whether to send the beam report based on the feedback information. Based on this, in some embodiments, when the network device receives the first information sent by the terminal, if it is determined that the uplink resource corresponding to the terminal is occupied by other terminals except the terminal, the second information fed back by the network device to the terminal can indicate that the terminal does not send the beam report, or can indicate that the terminal sends the beam report on the uplink resource that is not occupied by other terminals, thereby avoiding collision of beam reports of multiple terminals on the same resource, and ensuring successful sending of the beam reports of multiple terminals.

[0048] In some embodiments of the first aspect, the terminal is configured with a periodic uplink resource.

[0049] The sending or not sending of the beam report based on the second information comprises:

[0050] Determining, based on the second information, whether to send the beam report on the uplink resource after the first information.

[0051] In the above embodiments, when the terminal is configured with a periodic uplink resource, the second information is used by the terminal to determine whether to send the beam report on the uplink resource after the first information, so that, when the network device receives the first information, if it is determined that the uplink resource after the first information of the terminal is occupied by other terminals except the terminal, the second information fed back by the network device to the terminal can indicate that the terminal does not send the beam report, or can indicate that the terminal sends the beam report on the uplink resource that is not occupied by other terminals, thereby avoiding collision of beam reports of multiple terminals on the same resource, and ensuring successful sending of the beam reports of multiple terminals.

[0052] In some embodiments of the first aspect, the second information is used to indicate that the terminal sends or does not send the beam report on the first uplink resource after the first information.

[0053] In some embodiments of the first aspect, the sending or not sending of the beam report based on the second information comprises:

[0054] if the second information indicates that the terminal does not send the beam report on the first uplink resource after the first information, the terminal does not send the beam report on the first uplink resource after the first information.

[0055] if the second information indicates that the terminal does not send the beam report on the first uplink resource after the first information, the terminal does not send the beam report on the first uplink resource after the first information.

[0056] In some embodiments of the first aspect, in some embodiments, the second information is used to indicate that the terminal sends the beam report on an i-th uplink resource after the first information, i being a positive integer.

[0057] The sending or not sending the beam report based on the second information comprises:

[0058] sending the beam report on the i-th uplink resource after the first information.

[0059] In some embodiments of the first aspect, in some embodiments, the second information is used to indicate at least one first probability threshold, the first probability threshold corresponding to an uplink resource after the first information, the first probability threshold being used to indicate a probability of sending a beam report on the uplink resource corresponding to the first probability threshold.

[0060] In some embodiments of the first aspect, in some embodiments, the method further comprises:

[0061] when the terminal does not send the beam report on the first uplink resource after the first information, sending the first information again before a second uplink resource after the first information.

[0062] In some embodiments of the first aspect, in some embodiments, the method further comprises:

[0063] determining a second probability threshold, the second probability threshold being used to indicate a probability of sending the first information, the second probability threshold being determined by a protocol and / or configured by a network device.

[0064] In some embodiments of the first aspect, in some embodiments, the method further comprises:

[0065] not sending the first information before an i-th uplink resource after the first information.

[0066] In the above embodiments, the content indicated by the second information is limited, and a method for how the terminal sends or does not send the beam report based on the second information is provided. Through the method, when the terminal sends the beam report based on the second information, collision of the beam report with other terminals can be successfully avoided, and successful sending of the beam report is achieved. Or, when the terminal determines based on the second information that the beam report of the terminal may collide with the beam report of other terminals, the terminal can not send the beam report, ensuring successful sending of the beam report of other terminals, and improving the success rate of sending the beam report.

[0067] In some embodiments of the first aspect, the method further includes:

[0068] After the terminal sends the beam report, if no acknowledgement feedback sent by the network device is received, the first information is re-sent before the first uplink resource after the uplink resource occupied by the beam report is reached, and / or the beam report is sent on the first uplink resource after the uplink resource occupied by the beam report.

[0069] In some embodiments of the first aspect, the method further includes:

[0070] A third probability threshold is determined, the third probability threshold is used to indicate a probability of sending the first information and / or sending the beam report, and the third probability threshold is determined by a protocol and / or configured by the network device.

[0071] In the above embodiments, after the terminal sends the beam report, if no acknowledgement feedback sent by the network device is received, such as no feedback of the network device is received or negative acknowledgement (NACK) of the network device is received, at this time, it is considered that the beam report is not successfully sent. The terminal can re-send the first information to re-receive the second information sent by the network device, and re-send the beam report based on the second information, and / or the terminal can directly re-send the beam report, thereby achieving repeated sending of the beam report, and improving the success rate of sending the beam report.

[0072] In some embodiments of the first aspect, the sending of the first information includes:

[0073] The first information is sent when at least one first condition is met, and the first condition is used to trigger the terminal to send the beam report.

[0074] In the above embodiments, when at least one first condition is met, the terminal sends first information to inform the network device that the terminal will send a beam report. Therefore, in the method of the present disclosure, whether the terminal sends a beam report is determined based on whether the first condition is met. By flexibly setting the first condition, the terminal can timely and accurately report the beam report at the appropriate time, avoiding the situation that the network device configures a beam report interval that is too short, which may cause the best beams of two reports to be the same without change, thereby wasting signaling, or the network device configures a beam report interval that is too long, which may cause the beam quality to change without reaching the reporting time, thereby affecting the communication quality. Therefore, the signaling overhead can be reduced, and the communication quality can be ensured when the beam quality changes.

[0075] In some embodiments in combination with the first aspect, in some embodiments, the beam report comprises at least one of:

Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0391] Optionally, in a communication system, when a terminal sends a beam report to a network device, the network device usually configures a reporting occasion for the terminal to report the beam report, and then the terminal reports the beam report based on the reporting occasion configured by the network device. Optionally, the network device usually configures the terminal to report the beam report periodically, semi-persistently, or aperiodically. However, in fact, the terminal can learn the change of beam quality in time, and the reporting occasion configured by the network device (such as the period length of periodic reporting or the reporting occasion of aperiodic reporting) may not be the most appropriate. For example, if the reporting interval is too short, the best beams reported twice may be the same, and there is no change, thereby wasting signaling; if the reporting interval is too long, the situation that the beam quality changes but the terminal does not report due to not reaching the reporting occasion may occur, thereby affecting the communication quality. At present, an event-triggered beam report has been proposed to solve the above problems, that is, the terminal determines whether a triggering event is met based on the beam quality of the terminal, and when the triggering event is met, the terminal sends a beam report, thereby realizing timely and accurate reporting of the beam report, reducing the latency of the beam report, and also, the network device does not need to configure a reporting occasion for the terminal to report the beam report, thereby reducing the signaling overhead.

[0392] Optionally, in some embodiments, when the terminal sends a beam report based on a triggering event, the following two methods are introduced:

[0393] Firstly, when the terminal meets the triggering event, the terminal sends an uplink indication (UL indication) to the network device, and the uplink indication is used to inform the network device that the terminal will send a beam report. Optionally, in some embodiments, when the terminal has been configured (such as pre-configured) with periodic or semi-persistent resources for beam reporting, the uplink indication can also be used to indicate that the terminal will send a beam report on the next resources, and then the network device can reserve the next resources for the terminal in advance for beam reporting, so that the terminal can directly send a beam report on the resources subsequently without requesting resources, thereby reducing the latency of the beam report of the terminal. Moreover, when the terminal does not send an uplink indication to the network device, the network device can also schedule the periodic or semi-persistent resources pre-configured to the terminal for other transmissions, thereby improving the resource utilization.

[0394] The second method is that when the terminal satisfies the triggering event, the terminal first sends an uplink indication (UL indication) to the network device, the uplink indication is used to inform the network device that the terminal will send the beam report, and the uplink indication can also request the network device to configure the resource for the beam report, and then the network device can dynamically configure the resource for the beam report to the terminal based on the uplink indication, so that the terminal sends the beam report on the resource, ensuring the timely sending of the beam report.

[0395] However, for the first method, in order to save resources, the pre-configured periodic or semi-persistent resource for the beam report can be shared by multiple terminals. At this time, if the uplink resource indicated by the aforementioned "uplink indication" is occupied by other terminals in advance, if the terminal continues to send the beam report on the resource, it will cause the beam reports of multiple terminals to collide on the same resource, so that the beam reports of multiple terminals are not successfully sent, thereby affecting the normal reporting of the beam report.

[0396] Based on this, the present disclosure provides a beam report method for solving the above technical problems.

[0397] FIG. 2A is an interaction schematic diagram of a beam report method according to an embodiment of the present disclosure. As shown in FIG. 2A, the embodiment of the present disclosure relates to a beam report method for the communication system 100, and the method comprises the following steps:

[0398] In step 2101, the network device configures at least one first condition.

[0399] Optionally, the network device can configure the first condition to the terminal, and the terminal can receive the first condition configured by the network device.

[0400] In some embodiments, the first condition can be used to trigger the terminal to send the beam report, wherein when the terminal satisfies the first condition, the terminal can trigger to send the beam report. In some embodiments, the first condition can also be referred to as a triggering event or other names, which are not limited in the present disclosure.

[0401] Optionally, the "triggering to send the beam report" can be understood as starting to prepare to generate and send the beam report, that is, the beam report has not been sent yet, but will be sent soon.

[0402] Optionally, in some embodiments, the first condition can include one or more of the following:

[0403] The beam quality of the first beam is lower than a first threshold value;

[0404] The beam quality of the second beam is higher than a second threshold value;

[0405] The beam quality of the second beam is higher than the beam quality of the first beam by a first offset value;

[0406] When the first beam is used for an uplink transmission configuration indication state (UL TCI state), a power backoff value of the first beam is higher than a third threshold value;

[0407] When the second beam is used for the UL TCI state, a power backoff value of the second beam is lower than a fourth threshold value;

[0408] When the second beam is used for the UL TCI state, the power backoff value of the second beam is lower than the power backoff value of the first beam by a second offset value.

[0409] Optionally, the first threshold value, the second threshold value, the third threshold value, the fourth threshold value, the first offset value, and the second offset value can be configured by the network device, or can be agreed by a protocol. In addition, the first threshold value, the second threshold value, the third threshold value, and the fourth threshold value can be the same or different. The first offset value and the second offset value can be the same or different.

[0410] Optionally, in some embodiments, the first beam can include at least one of the following:

[0411] A best beam in the last beam report, i.e., a beam with the best beam quality in the last beam report;

[0412] A beam corresponding to a joint transmission configuration indication state (joint TCI state) indicated by the network device recently;

[0413] A beam corresponding to a downlink transmission configuration indication state (DL TCI state) indicated by the network device recently;

[0414] A beam corresponding to an UL TCI state indicated by the network device recently;

[0415] A beam corresponding to a joint TCI state activated by the network device recently;

[0416] A beam corresponding to a DL TCI state activated by the network device recently;

[0417] a beam corresponding to a UL TCI state recently activated by the network device;

[0418] all beams in the last beam report;

[0419] a worst beam in the last beam report, i.e., a beam with the worst beam quality in the last beam report.

[0420] Optionally, in some embodiments, the second beam can include at least one of:

[0421] a non-best beam in the last beam report;

[0422] a beam other than a beam in the last beam report;

[0423] a beam other than a beam corresponding to a joint TCI state recently indicated by the network device;

[0424] a beam other than a beam corresponding to a DL TCI state recently indicated by the network device;

[0425] a beam other than a beam corresponding to a UL TCI state recently indicated by the network device;

[0426] a beam corresponding to a TCI state other than a TCI state recently indicated by the network device in a TCI state list of the first signaling configuration;

[0427] a beam other than a beam corresponding to a joint TCI state recently activated by the network device;

[0428] a beam other than a beam corresponding to a DL TCI state recently activated by the network device;

[0429] a beam other than a beam corresponding to a UL TCI state recently activated by the network device;

[0430] a beam corresponding to a TCI state other than a TCI state recently activated by the network device in a TCI state list of the first signaling configuration;

[0431] a beam corresponding to a TCI state other than a TCI state recently indicated by the network device in the TCI state recently activated by the network device.

[0432] Optionally, the first signaling can be, for example, a radio resource control (RRC) signaling, and the "TCI state recently indicated by the network device" can include, for example, at least one of a joint TCI state recently indicated by the network device, a DL TCI state recently indicated by the network device, and a UL TCI state recently indicated by the network device. Optionally, the "TCI state recently indicated by the network device" can include a TCI state indicated by the network device based on downlink control indicator (DCI) signaling.

[0433] Optionally, the "TCI state recently activated by the network device" may, for example, include at least one of the following: a joint TCI state recently activated by the network device, a DL TCI state recently activated by the network device, and a UL TCI state recently activated by the network device. Optionally, the "TCI state recently activated by the network device" may include a unified TCI state (unified TCI state) activated by the network device based on a first Medium Access Control Control Element (MAC CE), which is used for transmission of at least one channel and / or at least one reference signal, including at least two of the following: a Physical Downlink Control Channel (PDCCH), a Physical Downlink Shared Channel (PDSCH), a Physical Uplink Control Channel (PUCCH), a Physical Uplink Shared Channel (PUSCH), a Channel-state information reference signal (CSI-RS), and a sounding reference signal (SRS). The "TCI state recently activated by the network device" may also include a TCI state of a PDCCH activated by the network device based on a second MAC CE, which is dedicated to transmission of a Control Resource Set (CORESET) corresponding to a CORESET ID indicated in the second MAC CE.

[0434] Optionally, in some embodiments, the first beam may be understood as a current beam of the terminal, and the second beam may be understood as a candidate beam of the terminal. When the "beam quality of the first beam is lower than the first threshold value", it means that the beam quality of the first beam is low, i.e., the beam direction of the first beam is not aligned with the terminal, and the quality of communication based on the first beam may be poor at this time. Therefore, the terminal cannot communicate based on the first beam and needs to switch the beam. Thus, the terminal may send a beam report to enable the network device to configure the terminal to perform beam switching based on the beam report.

[0435] Optionally, in some embodiments, when the "beam quality of the second beam is higher than a second threshold value, or the beam quality of the second beam is higher than the beam quality of the first beam by a first offset value" is satisfied, it means that the beam quality of the second beam is higher, i.e., the beam direction of the second beam is aligned to the terminal, and at this time, the quality of communication based on the second beam is likely to be better, so that the terminal can be triggered to send a beam report to make the network device configure the terminal to perform beam switching based on the beam report.

[0436] Optionally, in some embodiments, when the "power backoff value of the first beam is higher than a third threshold value" is satisfied, it means that in order to meet the maximum permissible exposure (MPE) of the terminal, the power backoff value (i.e., the power value that needs to be reduced) of the first beam is larger, i.e., the uplink transmission power in the beam direction of the first beam is smaller, so that the terminal cannot communicate based on the first beam, and needs to switch the beam, so that the terminal can be triggered to send a beam report to make the network device configure the terminal to perform beam switching based on the beam report.

[0437] Optionally, in some embodiments, when the "power backoff value of the second beam is lower than a fourth threshold value, or the power backoff value of the second beam is lower than the power backoff value of the first beam by a second offset value" is satisfied, it means that in order to meet the MPE of the terminal, the power backoff value (i.e., the power value that needs to be reduced) of the second beam is smaller, i.e., the uplink transmission power in the beam direction of the second beam is larger, so that the terminal can be switched to communicate on the second beam, and at this time, the terminal can be triggered to send a beam report to make the network device configure the terminal to perform beam switching based on the beam report.

[0438] Optionally, the beam report can include at least one of the following:

[0439] At least one first identifier, which can be a resource identifier of the first reference signal resource, and the first reference signal resource can be a reference signal resource that satisfies a first condition;

[0440] A unified TCI state type recommended by the terminal;

[0441] A TCI state corresponding to the first reference signal resource;

[0442] A power headroom corresponding to the first reference signal resource;

[0443] A first indication, which can be used to indicate whether a power management maximum power reduction (P-MPR) corresponding to the first reference signal resource is lower than a first value; the first value can be a protocol agreement and / or a network device configuration;

[0444] A second indication, which can be used to indicate a power backoff value corresponding to the first reference signal resource in order to meet the MPE when the P-MPR corresponding to the first reference signal resource is greater than the first value;

[0445] A third indication, which can be used to indicate a maximum number of SRS antenna ports supported by the first reference signal resource;

[0446] A second identification, which can be an event ID of a first condition triggering the terminal to send a beam report;

[0447] A beam quality of the first reference signal resource;

[0448] A third identification (or reportID or reportconfigID), which can be associated with at least one of the following: the event ID, a determination parameter corresponding to the first condition, the first reference signal resource, a reference signal resource set in which the first reference signal resource is located, and a beam quality type required to be reported;

[0449] A cell identification, which can include a serving cell identification or other cell identification, the serving cell identification can be a cell identification of a serving cell of the terminal, and the other cell identification can be a cell identification of a cell other than the serving cell of the terminal;

[0450] A component carrier index corresponding to the first reference signal resource.

[0451] Optionally, the above-mentioned “the first reference signal resource is a reference signal resource satisfying the first condition” can be understood as, for example, a beam corresponding to the first reference signal resource satisfies the first condition, and the “beam corresponding to the first reference signal resource” can be, for example, a beam used to transmit the first reference signal resource.

[0452] In some embodiments, the above-mentioned first identification can be a synchronization signal block identification (SSB ID), which can be used to indicate an SSB resource; or the first identification can be a CSI-RS ID, which can be used to indicate a CSI-RS resource.

[0453] It should be noted that in some embodiments, when the "beam corresponding to the first reference signal resource" is the second beam, at this time, the "beam corresponding to the first reference signal resource" can be understood as: the new beam (or called target beam) to be switched by the terminal, at this time, if the first identifier is the SSB ID, the beam report can further indicate whether the cell corresponding to the SSB ID is a serving cell or a non-serving cell of the terminal; and if the cell corresponding to the SSB ID is a non-serving cell of the terminal, the beam report can further indicate the index of the non-serving cell corresponding to the SSB ID in the additional Physical Cell Identifier list (additional PCI list). Optionally, the beam report can further indicate the serving cell index corresponding to the reference signal resource identifier (i.e., the first identifier, or the resource identifier), for example, when the terminal is configured with multiple serving cells, the beam report can indicate the serving cell index, servingcellindex or ComponentcarrierID. Optionally, multiple reference signal resource identifiers in one beam report can correspond to the same serving cell index, or correspond to one serving cell index respectively.

[0454] Optionally, the "Unified TCI state type" can include, for example, a joint TCI state or a separate TCI state.

[0455] Optionally, the "TCI state corresponding to the first reference signal resource" can include at least one of a joint TCI state, an UL TCI state, or a DL TCI state.

[0456] Optionally, in some embodiments, when the TCI state corresponding to the first reference signal resource is joint TCI state, if the terminal has indicated in the beam report that the terminal recommended Unified TCI state type is joint TCI state, or if the network device has configured the terminal with Unified TCI state type as joint TCI state and the terminal cannot change the joint TCI state, the terminal does not need to repeatedly report in the beam report that the TCI state corresponding to the first reference signal resource is joint TCI state. In other words, in some embodiments, when the terminal does not report in the beam report that the terminal recommended Unified TCI state type is joint TCI state, and / or the network device configured unified TCI state type can be changed by the terminal, the terminal can report in the beam report that the TCI state corresponding to the first reference signal resource is joint TCI state.

[0457] Optionally, in some embodiments, when the TCI state corresponding to the first reference signal resource is DL TCI state, it can be that the terminal reports in the beam report that the TCI state corresponding to the first reference signal resource is DL TCI state only when the network device configured unified TCI state type is separate TCI state, or when the terminal reports in the beam report that the terminal recommended Unified TCI state type is separate TCI state, or when the terminal does not report in the beam report that the terminal recommended Unified TCI state type.

[0458] Optionally, in some embodiments, when the TCI state corresponding to the first reference signal resource is UL TCI state, it can be that the terminal reports in the beam report that the TCI state corresponding to the first reference signal resource is UL TCI state only when the network device configured unified TCI state type is separate TCI state, or when the terminal reports in the beam report that the terminal recommended Unified TCI state type is separate TCI state, or when the terminal does not report in the beam report that the terminal recommended Unified TCI state type.

[0459] Optionally, in some embodiments, when the third indication is used to indicate the maximum number of SRS antenna ports supported by the first reference signal resource, it is equivalent to indicating the terminal antenna panel (panel) identifier corresponding to the first reference signal resource.

[0460] In some embodiments, the power headroom corresponding to the first reference signal resource, the first indication, the second indication, and the third indication are reported to the network device only when the TCI state corresponding to the first reference signal resource is an UL TCI state. Optionally, the power headroom corresponding to the first reference signal resource, the first indication, the second indication, and the third indication can be used to inform the network device why the terminal sends the beam report. For example, the beam report can be sent due to the MPE of the terminal triggering the first condition, or the beam report can be sent due to the terminal switching the antenna panel (panel).

[0461] Optionally, in some embodiments, the second identifier is a condition identifier of the first condition triggering the terminal to send the beam report. Different first conditions correspond to different condition identifiers. It should be noted that in some embodiments, the condition identifier can implicitly indicate the TCI state corresponding to the reference signal resource. Specifically, for example, each TCI state corresponding to the reference signal resource can correspond to one or more first conditions. Since the first condition has a corresponding relationship with the condition identifier, and the first condition has a corresponding relationship with the TCI state of the reference signal resource, the TCI state of the reference signal resource corresponding to the condition identifier can be implicitly determined based on the condition identifier based on the above-mentioned corresponding relationship after the condition identifier is known. For example, condition 1 is a condition corresponding to reporting the reference signal resource identifier for the DL TCI state, and condition 2 is a condition corresponding to reporting the reference signal resource identifier for the UL TCI state.

[0462] For example, assuming that a certain reference signal resource can be used for UL TCI state or joint TCI state, two TCI states corresponding to the reference signal resource can be associated with a first condition, respectively. Optionally, taking the UL TCI state corresponding to the reference signal resource as an example, the first condition associated with the UL TCI state corresponding to the reference signal resource can include, for example:

[0463] The first event: the beam quality corresponding to the reference signal resource is higher than a first threshold; and

[0464] The second event: a power backoff value of a beam corresponding to the reference signal resource is lower than a fourth threshold value.

[0465] Based on this, when the reference signal resource satisfies the first event and the second event, the TCI state corresponding to the reference signal resource is implicitly determined as the UL TCI state by reporting the first condition identifiers of the first event and the second event.

[0466] In some embodiments, when the second identifier can implicitly indicate the TCI state corresponding to the first reference signal resource, the TCI state corresponding to the first reference signal resource can not be reported in the beam report, thereby saving resource overhead. When the second identifier cannot implicitly indicate the TCI state corresponding to the first reference signal resource, for example, if the correspondence between the first condition and the TCI state of the reference signal resource is not set, the TCI state corresponding to the first reference signal resource can be reported in the beam report.

[0467] Optionally, the "beam quality" may, for example, include at least one of: a Layer 1 Reference Signal Received Power (L1-RSRP), a Layer 1 Signal to Interference plus Noise Ratio (L1-SINR), and an uplink transmission power.

[0468] Optionally, the "determination parameter corresponding to the first condition associated with the third identifier" may, for example, include a threshold corresponding to the first condition, an offset value, a timer, a counter, and the like. For example, the determination parameter corresponding to the first condition can be at least one of the aforementioned "first offset value, second offset value, first threshold value, second threshold value, third threshold value, and fourth threshold value".

[0469] Further, in some embodiments, the above-mentioned “beam” is only an example naming of the present disclosure, which can also be other names, for example, the beam can be referred to as: beam, common beam, spatial Rx parameter, quasi-co location Type (QCL Type) Type D, spatial setting, spatial reception filter, spatial transmission filter, spatial domain filter, TCI state, joint TCI state, DL TCI state, UL TCI state, unified TCI state, common Transmission Configuration Indication state (common TCI state), spatial relation information (spatialrelationinfo), etc.

[0470] Optionally, the above-mentioned common beam can refer to multiple channels or multiple reference signals using the same beam, at this time, using one beam indication signaling can indicate the common beam of multiple channels or multiple reference signals, thereby saving signaling.

[0471] Step 2102, the network device configures a first resource.

[0472] Optionally, the network device can configure the first resource for the terminal, and the terminal can receive the first resource configured by the network device.

[0473] Optionally, the first resource can be used for the terminal to send first information, and the first information can be used for the terminal to inform the network device that the terminal will send a beam report. Optionally, the first information can be sent to the network device when the terminal determines that at least one first condition is met. That is, when the terminal sends the first information, the beam report has not been sent to the network device, but is about to be sent to the network device. In some embodiments, the first information can be the “uplink indication (UL indication)” described in the content before the embodiment of FIG. 2A.

[0474] Optionally, in some embodiments, the different reference signal resources can respectively correspond to first resources, where the first resource corresponding to the reference signal resource can be used to transmit the first information on the first resource corresponding to the reference signal resource when the reference signal resource satisfies at least one first condition. Optionally, the different reference signal resources can include, for example, CSI-RS or SSB. And by making the different reference signal resources respectively correspond to first resources, the network device can determine which reference signal resources triggered the transmission of the beam report based on the resources used by the terminal to transmit the first information, that is, when the network device receives the first information, the terminal has not yet transmitted the beam report, at this time, the network device can already know which first reference signal resources triggered the beam report, and therefore, when the terminal subsequently transmits the beam report to the network device, it can no longer need to report the aforementioned first identifier, thereby saving resource overhead.

[0475] Optionally, in some embodiments, the different first conditions can respectively correspond to first resources, where the first resource corresponding to the first condition can be used to transmit the first information on the first resource corresponding to the first condition when the reference signal resource satisfies the first condition. And by making the different first conditions respectively correspond to first resources, the network device can determine which first conditions triggered the transmission of the beam report based on the resources used by the terminal to transmit the first information, that is, when the network device receives the first information, the terminal has not yet transmitted the beam report, at this time, the network device can already know which first conditions triggered the beam report, and therefore, when the terminal subsequently transmits the beam report to the network device, it can no longer need to report the aforementioned second identifier, and when the condition identifier (i.e., the second identifier) of the first condition can implicitly indicate the TCI state corresponding to the reference signal resource, the beam report can no longer need to report the TCI state corresponding to the first reference signal resource, thereby greatly saving resource overhead.

[0476] Optionally, in some embodiments, the first resource described above can include at least one of the following:

[0477] A random access occasion (RO), for example, a time domain and / or frequency domain resource;

[0478] A scheduling request (SR) resource, for example, a time-frequency resource and / or a sequence;

[0479] Uplink control information (UCI).

[0480] Optionally, the first information can be a preamble carried in Msg 1 or Msg A, or the first information can be carried in a PUCCH. Alternatively, the first information can be carried in an SR.

[0481] For example, when the first resource is an RO, the first information can be a preamble carried in Msg 1 or Msg A; when the first resource is an SR resource, the first information can be carried in an SR; and when the first resource is UCI, the first information can be carried in a PUCCH. The UCI can be UCI other than SR, CSI, and Hybrid Automatic Retransmission Request Acknowledgement (HARQ-ACK) feedback.

[0482] In some embodiments, the first resource can be dedicated to transmitting the first information and cannot be used to transmit other information. For example, when the first resource is an RO, the RO cannot be used for a conventional random access procedure or a random access initiated by a beam failure random access procedure. For another example, when the first resource is an SR, the SR cannot be used for a request for a conventional PUSCH resource, but can only be used to reserve or request a PUCCH or PUSCH resource for a beam report.

[0483] At step 2103, the network device configures a periodic uplink resource for the terminal.

[0484] Optionally, in some embodiments, the periodic uplink resource can be used by the terminal to transmit a beam report. The uplink resource can include at least one of the following, for example:

[0485] a PUSCH;

[0486] a PUCCH.

[0487] At step 2104, the terminal determines at least one first condition.

[0488] For details of the first condition, refer to the description of the above steps.

[0489] Optionally, in some embodiments, the terminal can determine the at least one first condition based on a protocol agreement, and in other embodiments, the terminal can receive at least one first condition configured by the network device.

[0490] At step 2105, the terminal determines a first resource.

[0491] For details of the first resource, refer to the description of the above steps.

[0492] Optionally, in some embodiments, the terminal can determine the first resource based on a protocol agreement, and in some other embodiments, the terminal can receive the first resource configured by the network device.

[0493] Step 2106, the terminal sends the first information.

[0494] Optionally, in some embodiments, the terminal can send the first information to the network device, and the network device can receive the first information. Optionally, the terminal can send the first information when it is determined that at least one first condition is met. The details of the first condition and the first information can be referred to the description of the above steps.

[0495] Optionally, the terminal can send the first information on the first resource. The details of the first resource can be referred to the description of the above steps.

[0496] Step 2107, the network device sends the second information.

[0497] Optionally, in some embodiments, the second information can be used by the terminal to determine whether to send the beam report. For example, in some embodiments, the second information can be used by the terminal to determine whether to send the beam report on the uplink resource after the first information.

[0498] In different cases, the specific indication meaning of the second information can be different, and the method of sending the second information by the network device is described in detail as follows.

[0499] In some embodiments, the second information can be used to indicate that the terminal sends or does not send the beam report on the first uplink resource after the first information. Specifically, in some embodiments, when the first uplink resource after the first information is occupied by other terminals (i.e., terminals other than the terminal sending the first information in the above step 2106), the second information sent by the network device can be used to indicate that the terminal does not send the beam report on the first uplink resource after the first information; in some other embodiments, when the first uplink resource after the first information is not occupied by other terminals, the second information sent by the network device can be used to indicate that the terminal sends the beam report on the first uplink resource after the first information.

[0500] In some embodiments, the second information can be used to indicate that the terminal transmits the beam report on the i-th uplink resource after the first information, where i is a positive integer. Optionally, the i-th uplink resource after the first information can be, for example, an uplink resource that is closest to the first information in time domain and is not occupied by other terminals. For example, assuming that one other terminal occupies the first uplink resource after the first information before the terminal, the second information can be used to indicate that the terminal transmits the beam report on the second uplink resource after the first information; or, assuming that N other terminals occupy the first uplink resource, the second uplink resource, …, the N-th uplink resource after the first information before the terminal, the second information can be used to indicate that the terminal transmits the beam report on the N+1-th uplink resource after the first information.

[0501] In some embodiments, the second information can be used to indicate at least one first probability threshold. Optionally, the first probability threshold can correspond to an uplink resource after the first information, for example, the first probability threshold can be used to indicate the probability of transmitting the beam report on the uplink resource corresponding to the first probability threshold. In some embodiments, the second information transmitted by the network device can be used to indicate at least one first probability threshold only when the first uplink resource after the first information is occupied by other terminals. In addition, the number of uplink resources between the uplink resource corresponding to the first probability threshold indicated by the second information and the first information can be less than or equal to a preset threshold, for example, the preset threshold can be M, where M is a positive integer. For example, when M = 3, it means that the uplink resource corresponding to the first probability threshold indicated by the second information can be separated from the first information by at most 3 uplink resources, and the second information can indicate the first uplink resource, the second uplink resource, the third uplink resource, and the fourth uplink resource that are sequentially adjacent to the first information. In some embodiments, the first probability threshold corresponding to the uplink resource occupied by other terminals can be less than the first probability threshold corresponding to the uplink resource not occupied by other terminals.

[0502] Optionally, the reason for making the first probability threshold corresponding to the uplink resource occupied by other terminals less than the first probability threshold corresponding to the uplink resource not occupied by other terminals is mainly to reduce the probability of the terminal transmitting the beam report on the uplink resource occupied by other terminals and increase the probability of the terminal transmitting the beam report on the uplink resource not occupied by other terminals, thereby reducing the beam report collision probability while ensuring that the beam report of the terminal can be transmitted as soon as possible.

[0503] Specifically, in some embodiments, the first probability threshold can have the following function: after receiving the first probability threshold indicated by the network device through the second information, the terminal will randomly generate a first probability value when it is about to reach the uplink resource corresponding to the first probability threshold, for example, a first probability value is randomly generated before 0-1, when the first probability value is greater than or equal to the first probability threshold, no beam report is sent on the uplink resource, and when the first probability value is less than or equal to the first probability threshold, the beam report is sent on the uplink resource. Based on this, when the first probability threshold corresponding to the uplink resource occupied by other terminals is less than the first probability threshold corresponding to the uplink resource not occupied by other terminals, since the first probability threshold corresponding to the uplink resource occupied by other terminals is smaller (such as 30%), the probability that the first probability value randomly generated by the terminal is less than or equal to the first probability threshold corresponding to the uplink resource occupied by other terminals is lower (i.e. the probability that the randomly generated first probability value is less than 30% is very low), so that the beam report transmission probability on the uplink resource occupied by other terminals is lower, and since the first probability threshold corresponding to the uplink resource not occupied by other terminals is larger (such as 80%), the probability that the first probability value randomly generated by the terminal is less than or equal to the first probability threshold corresponding to the uplink resource not occupied by other terminals is higher, so that the beam report transmission probability on the uplink resource not occupied by other terminals is higher, at this time, the beam report transmission rate on the uplink resource occupied by other terminals is less than the beam report transmission rate on the uplink resource not occupied by other terminals, that is, the terminal is not easy to send the beam report on the uplink resource occupied by other terminals, but is easy to send the beam report on the uplink resource not occupied by other terminals. Therefore, the network device can flexibly set the first probability threshold corresponding to the uplink resource according to the occupation of the uplink resource by other terminals, thereby avoiding the collision of the beam report of the terminal with the beam report of other terminals, while also ensuring that the beam report of the terminal can be successfully sent on the uplink resource not occupied by other terminals, ensuring the success rate of beam report transmission.

[0504] In some embodiments, for the uplink resource occupied by other terminals, the farther the interval is from the first information, the corresponding first probability threshold can gradually increase, so that when the terminal determines whether to send the beam report on the uplink resource according to the corresponding first probability threshold in the order of the appearance of the uplink resource after the first information, the probability of sending the beam report on the next uplink resource can be gradually increased in sequence, thereby greatly increasing the success rate of beam report transmission.

[0505] Based on this, the above content is exemplarily introduced. For example, assuming that one other terminal occupies the first uplink resource after the first information before the terminal, the second information can be used to indicate two first probability thresholds corresponding to the first uplink resource and the second uplink resource after the first information, respectively. The first probability threshold corresponding to the first uplink resource after the first information can be less than the first probability threshold corresponding to the second uplink resource after the first information. For example, the first probability threshold corresponding to the first uplink resource after the first information can be lower than 10%, such as 5%. The first probability threshold corresponding to the second uplink resource after the first information can be higher than 80%, such as 90%. Alternatively, assuming that two other terminals occupy the first uplink resource and the second uplink resource after the first information before the terminal, respectively, the second information can be used to indicate three first probability thresholds corresponding to the first uplink resource, the second uplink resource, and the third uplink resource after the first information, respectively. The first probability threshold corresponding to the first uplink resource after the first information can be less than the first probability threshold corresponding to the second uplink resource after the first information, and the first probability threshold corresponding to the second uplink resource after the first information can be less than the first probability threshold corresponding to the third uplink resource after the first information. For example, the first probability threshold corresponding to the first uplink resource after the first information can be lower than 10%, such as 5%. The first probability threshold corresponding to the second uplink resource after the first information can be lower than 30%, such as 20%. The first probability threshold corresponding to the third uplink resource after the first information can be higher than 80%, such as 90%.

[0506] Step 2108: The terminal sends or does not send a beam report based on the second information.

[0507] Optionally, in some embodiments, when the terminal sends a beam report based on the second information, the terminal can send the beam report to the network device, and the network device can receive the beam report.

[0508] Optionally, in some embodiments, when the second information indicates different meanings, the specific execution method of this step will also be different.

[0509] In some embodiments, when the second information indicates that the terminal sends or does not send a beam report on the first uplink resource after the first information, if the second information indicates that the terminal sends a beam report on the first uplink resource after the first information, the terminal sends a beam report on the first uplink resource after the first information based on the second information; or if the second information indicates that the terminal does not send a beam report on the first uplink resource after the first information, the terminal does not send a beam report on the first uplink resource after the first information based on the second information.

[0510] In some embodiments, when the second information indicates that the terminal is to send the beam report on the i-th uplink resource after the first information, the terminal sends the beam report on the i-th uplink resource after the first information. And, before the i-th uplink resource after the first information, the terminal does not send the first information any more.

[0511] In some embodiments, when the second information indicates at least one first probability threshold, when the uplink resource corresponding to the first probability threshold is about to arrive, the terminal randomly generates a first probability value, for example, the terminal can randomly generate a first probability value between 0 and 1, wherein if the first probability value is greater than or equal to the first probability threshold corresponding to the uplink resource about to arrive, the terminal does not send the beam report on the uplink resource when the uplink resource arrives; if the first probability value is less than or equal to the first probability threshold corresponding to the uplink resource about to arrive, the terminal sends the beam report on the uplink resource when the uplink resource arrives.

[0512] For example, taking the second uplink resource after the first information as an example, assuming that the second information indicates that the first probability threshold corresponding to the second uplink resource after the first information is 20%, when the terminal sends the first information, the second uplink resource after the first information is about to arrive, if the first probability value randomly generated by the terminal is 30%, the terminal does not send the beam report on the second uplink resource after the first information, if the first probability value randomly generated by the terminal is 10%, the terminal sends the beam report on the second uplink resource after the first information.

[0513] It should be noted that in some embodiments, when the second information indicates at least one first probability threshold, the terminal can traverse all the uplink resources corresponding to the first probability thresholds to perform the above operation, that is, the terminal can determine whether to send the beam report on the corresponding uplink resource based on each first probability threshold indicated by the network device. For example, the network device indicates three first probability thresholds, which correspond to the first uplink resource, the second uplink resource and the third uplink resource after the first information in turn, the terminal can determine whether to send the beam report on the first uplink resource, the second uplink resource and the third uplink resource after the first information based on the three first probability thresholds.

[0514] Or, in some other embodiments, the terminal can only perform the above operation based on the first probability threshold corresponding to the first uplink resource after the first information, without performing the above operation based on other first probability thresholds, that is, the terminal can only determine whether to send the beam report on the first uplink resource after the first information based on the first probability threshold corresponding to the first uplink resource, without determining whether to send the beam report on the corresponding uplink resource based on other first probability thresholds.

[0515] Alternatively, in yet some embodiments, the terminal can traverse the uplink resources corresponding to the first probability thresholds until the beam report is successfully transmitted. For example, the network device indicates three first probability thresholds, which in turn correspond to a first uplink resource, a second uplink resource, and a third uplink resource after the first information, the terminal can first determine whether to transmit the beam report on the first uplink resource after the first information based on the first probability threshold corresponding to the first uplink resource, and when it is determined that the beam report is not transmitted on the first uplink resource, determine whether to transmit the beam report on the second uplink resource after the first information based on the first probability threshold corresponding to the second uplink resource, and when it is determined that the beam report is transmitted on the second uplink resource, transmit the beam report and stop operation.

[0516] Step 2109, when the terminal does not transmit the beam report on the first uplink resource after the first information, the terminal performs a first operation.

[0517] Optionally, in some embodiments, the first operation can be that before the second uplink resource after the first information, the first information is directly transmitted again, and the second information transmitted again by the network device is received (i.e., step 2107 is performed again), and whether to transmit the beam report is determined again based on the second information (i.e., step 2108 is performed again).

[0518] Alternatively, in some other embodiments, the first operation can be that before the second uplink resource after the first information, a second probability threshold is determined, the second probability threshold can be used to indicate the probability of transmitting the first information, and the second probability threshold can be agreed by the protocol and / or configured by the network device, and then the terminal randomly generates a second probability value. For example, the terminal can randomly generate a second probability value between 0 and 1, if the second probability value is less than or equal to the second probability threshold, the terminal transmits the first information again before the second uplink resource after the first information, receives the second information transmitted again by the network device (i.e., step 2107 is performed again), and determines whether to transmit the beam report again based on the second information (i.e., step 2108 is performed again). If the second probability value is greater than or equal to the second probability threshold, the terminal does not repeatedly transmit the first information before the second uplink resource after the first information, and does not transmit the beam report on the second uplink resource after the first information.

[0519] It should be noted that in some embodiments, this step 2109 can be performed when the second information in the above step 2107 indicates that the terminal does not send the beam report on the first uplink resource after the first information, or this step 2109 can be performed when the terminal determines not to send the beam report on the first uplink resource after the first information based on the first probability threshold corresponding to the first uplink resource after the first information.

[0520] Step 2110, after the terminal sends the beam report, if no acknowledgement (ACK) sent by the network device is received, the terminal performs a second operation.

[0521] Optionally, the above-mentioned "no ACK sent by the network device is received" can be understood as, for example, no feedback sent by the network device is received, or a negative acknowledgement (NACK) of the network device is received.

[0522] Optionally, in some embodiments, the above-mentioned second operation may, for example, include directly re-sending the first information before the first uplink resource after the uplink resource occupied by the last beam report arrives.

[0523] Optionally, in other embodiments, the above-mentioned second operation may, for example, include re-sending the beam report on the first uplink resource after the uplink resource occupied by the last beam report.

[0524] Optionally, in still other embodiments, the above-mentioned second operation may, for example, include that before the first uplink resource after the uplink resource occupied by the last beam report arrives, the terminal determines a third probability threshold, which is used to indicate the probability of sending the first information and / or sending the beam report; the third probability threshold can be agreed by the protocol and / or configured by the network device; then, the terminal randomly generates a third probability value; for example, the terminal can randomly generate a third probability value between 0 and 1, if the third probability value is less than or equal to the third probability threshold, the terminal re-sends the first information before the first uplink resource after the uplink resource occupied by the last beam report arrives, and / or re-sends the beam report on the first uplink resource after the uplink resource occupied by the last beam report; if the third probability value is greater than or equal to the third probability threshold, no first information is sent before the first uplink resource after the uplink resource occupied by the last beam report arrives, and no beam report is sent on the first uplink resource after the uplink resource occupied by the last beam report.

[0525] Optionally, in some embodiments, the second operation can comprise: determining a third probability threshold, and randomly generating a third probability value; if the third probability value is greater than or equal to the third probability threshold, not sending the first information before the first uplink resource after the uplink resource occupied by the last beam report arrives, and not sending the beam report on the first uplink resource after the uplink resource occupied by the last beam report; and sending the first information before the second uplink resource after the uplink resource occupied by the last beam report arrives, and / or sending the beam report on the second uplink resource after the uplink resource occupied by the last beam report.

[0526] Optionally, in some embodiments, the second operation can comprise: determining a third probability threshold, and randomly generating a third probability value; if the third probability value is greater than or equal to the third probability threshold, not sending the first information before the first uplink resource after the uplink resource occupied by the last beam report arrives, and not sending the beam report on the first uplink resource after the uplink resource occupied by the last beam report; and sending the first information before the second uplink resource after the uplink resource occupied by the last beam report arrives, and / or sending the beam report on the second uplink resource after the uplink resource occupied by the last beam report.

[0527] Optionally, in some embodiments, by making the fourth probability threshold greater than the third probability threshold, the probability of "sending the first information before the second uplink resource arrives after the uplink resource occupied by the last beam report" can be made greater than the probability of "sending the first information before the first uplink resource arrives after the uplink resource occupied by the last beam report", and the probability of "sending the beam report on the second uplink resource after the uplink resource occupied by the last beam report" can be made greater than the probability of "sending the beam report on the first uplink resource after the uplink resource occupied by the last beam report", so that the sending probability of the first information and / or the beam report can be gradually increased with the order of the uplink resources, and the successful sending of the beam report can be ensured.

[0528] In the above embodiments, when the terminal determines that at least one first condition for triggering the sending of the beam report is met, the terminal sends the first information to the network device to inform the network device that the terminal will send the beam report, then the network device sends second information to the terminal, the second information is used by the terminal to determine whether to send the beam report, and the terminal sends or does not send the beam report based on the second information. It can be seen that in the method of the present disclosure, when the terminal informs the network device that the terminal will send the beam report, the network device replies to the terminal with a feedback information (i.e., the second information) so that the terminal determines whether to send the beam report based on the feedback information. Based on this, in some embodiments, when the network device receives the first information sent by the terminal, if it is determined that the uplink resource corresponding to the terminal is occupied by other terminals except the terminal, the second information fed back by the network device to the terminal can indicate that the terminal does not send the beam report, or can indicate that the terminal sends the beam report on the uplink resource not occupied by other terminals, thereby avoiding the collision of the beam reports of multiple terminals on the same resource and ensuring the successful sending of the beam reports of multiple terminals.

For example, step 2101 can be implemented as an independent embodiment, step 2102 can be implemented as an independent embodiment, step 2103 can be implemented as an independent embodiment, step 2101+S2102 can be implemented as an independent embodiment, but not limited thereto.

[0530] In the present embodiment or example, each step can be independent, arbitrarily combined or exchanged in order, and optional modes or examples can be arbitrarily combined, and can be arbitrarily combined with any step of other embodiments or other examples.

[0712] FIG. 5 is an interaction schematic diagram of a beam reporting method according to an embodiment of the present disclosure. As shown in FIG. 5, the embodiment of the present disclosure relates to a beam reporting method for a communication system including a terminal, a network device, the method including at least one of:

[0713] Step 5101, the terminal sends first information.

[0714] Step 5102, the network device receives the first information.

[0716] Step 5104, the terminal receives the second information.

[0717] Step 5105, the terminal sends or does not send a beam report based on the second information.

[0718] The optional implementation of steps 5101-5105 can refer to the above-mentioned embodiment introduction.

[0719] In some embodiments, the above-mentioned method can include the method described in the above-mentioned communication system side, terminal side, network device side, etc. Embodiments will not be repeated here.

[0720] The beam reporting method related by the embodiments of the present disclosure can include at least one of steps 5101-5105. For example, step 5101 can be implemented as an independent embodiment, and step 5102 can be implemented as an independent embodiment, but not limited thereto.

[0721] In the embodiments or examples, each step can be independent, arbitrarily combined or the order exchanged, the optional mode or optional example can be arbitrarily combined, and can be arbitrarily combined with any step of other embodiments or other examples without contradiction.

[0722] The following is an exemplary introduction to the above-mentioned method.

[0723] 1. In response to satisfying a first condition, the terminal sends first information, the first information being used to initiate a beam report. The beam report is carried on PUSCH or PUCCH.

[0724] a) beam can be referred to as beam, spatial Rx parameter, QCL (quasi-co location) Type D, spatial setting, spatial reception filter, spatial transmission filter, spatial domain filter, TCI state, joint TCI state, DL TCI state, UL TCI state, unified TCI state, common TCI state, spatialrelationinfo, etc.

[0725] 2. Based on 1, the terminal receives the second information sent by the base station before sending the beam report on the first PUSCH or PUCCH, and determines whether to send the beam report on the next first PUSCH or PUCCH based on the second information.

[0726] a) The second information indicates whether the terminal sends or does not send the beam report on the next first PUSCH or PUCCH

[0727] i. For example, if the first PUSCH or PUCCH is occupied by other terminals, it indicates not to send; otherwise, it indicates to send

[0728] b) The second information indicates that the terminal sends on the next one, such as the first PUSCH or PUCCH, the second PUSCH or PUCCH, or the third PUSCH or PUCCH……, to send the beam report

[0729] i. Wherein the first, second, third represent the distance of time, the first represents the nearest one in the future, the second represents the next nearest one…… The first, second, third, fourth PUSCH or PUCCH can be periodic PUSCH or PUCCH resources.

[0730] 1. For example, only one other terminal sends UL indication in advance, occupying the first PUSCH or PUCCH, then the base station indicates the terminal to send on the second PUSCH or PUCCH

[0731] 2. For example, there are N other terminals that send UL indication in advance, occupying the first, second, …, N PUSCH or PUCCH, then the base station indicates the terminal to send on the N+1 PUSCH or PUCCH

[0732] c) the second information indicates a probability of transmitting the beam report on the next first PUSCH or PUCCH, or second PUSCH or PUCCH resource, or Nth PUSCH or PUCCH resource

[0733] 1. If only one other terminal transmits the UL indication in advance, occupying the first PUSCH or PUCCH, the base station indicates a higher probability, e.g., higher than 80%, for the terminal to transmit the beam report on the second PUSCH or PUCCH resource

[0734] a) a lower probability, e.g., lower than 10%, for transmitting on the first PUSCH or PUCCH resource

[0735] 2. If N (N is greater than or equal to 2) other terminals transmit the UL indication in advance, occupying the first, second, …, Nth PUSCH or PUCCH, the base station indicates a lower probability, e.g., lower than 30%, for the terminal to transmit on the second PUSCH or PUCCH resource

[0736] 3. According to 2a, if the second information indicates that the terminal does not transmit the beam report on the first PUSCH or PUCCH resource, the terminal transmits the first information again before the second PUSCH or PUCCH resource that appears after the first PUSCH or PUCCH resource.

[0737] a) and then receives the second information transmitted by the base station again to see if the terminal can transmit the beam report on the second PUSCH or PUCCH resource

[0738] b) Further, the terminal randomly determines a probability of transmitting the first information again before the second PUSCH or PUCCH resource, and if the probability is lower than a threshold, e.g., the threshold is 50%, the terminal transmits the first information again, otherwise, the terminal does not transmit the first information and does not transmit the beam report on the second PUSCH or PUCCH resource.

[0739] 4. According to 2b, if the second information indicates that the terminal transmits the beam report on the N+1th PUSCH or PUCCH resource, the terminal can not transmit the first information again before the second, third, …, N+1th PUSCH or PUCCH resource.

[0740] 5. Based on 1, after the terminal transmits the beam report on the first PUSCH or PUCCH resource, the terminal does not receive the acknowledgement feedback from the base station (including not receiving any feedback from the base station, or receiving the NACK feedback from the base station), the terminal transmits the first information again before the second PUSCH or PUCCH resource that appears after the first PUSCH or PUCCH resource.

[0741] a) Further, the terminal randomly determines a probability of sending the first information before sending the first information again on the second PUSCH or PUCCH resource, such as the probability is lower than a threshold, such as the threshold is 50%, then the first information is sent again.

[0742] b) Otherwise, neither the first information is sent nor the beam report is sent on the second PUSCH or PUCCH resource.

[0743] i. And the first information is sent directly before the third PUSCH or PUCCH resource, or a probability is randomly generated again, but this time the threshold can be 80%, that is, the probability of sending the first information is increased.

[0744] 6. According to 1, the beam report includes at least one of the following:

[0745] a) The ID of at least one reference signal resource used to determine the new beam

[0746] i. SSB ID

[0747] 1. Indicating whether it corresponds to a serving cell or a non-serving cell; if it is a non-serving cell, indicating the index of the non-serving cell in the additional PCI list

[0748] ii. CSI-RS ID

[0749] b) Indicating the type of unified TCI state used: joint TCI state or separate TCI state

[0750] c) Indicating that at least one reference signal resource reported is used for

[0751] i. Joint TCI state (if the terminal has indicated in b that the type of unified TCI state is joint, or the base station has configured the type of unified TCI state as joint and the terminal cannot change it, then this can not be needed. That is, if there is no b, and the type of unified TCI state configured by the base station can be changed by the terminal, then this can be included in the beam report)

[0752] ii. or for DL TCI state (only base station config unified TCI state type as separate or terminal indicate unified TCI state type as separate in b is needed or no b)

[0753] iii. or for UL TCI state (only base station config unified TCI state type as separate or terminal indicate unified TCI state type as separate in b is needed or no b). The following is mainly to inform why the new beam needs to be updated, such as because of MPE or because of switching panel.

[0754] 1. Power head room corresponding to reference signal resource

[0755] 2. P: whether the P-MPR corresponding to the reference signal resource is lower than P-MPR_00 (base station config or protocol specifies the value of P-MPR_00)

[0756] 3. MPE: if P shows greater than P-MPR_00, MPE indicates the power backoff value corresponding to the reference signal resource

[0757] 4. the maximum supported number of SRS antenna ports corresponding to reference signal resource

[0758] a) equivalent to the terminal panel identification corresponding to the reference signal resource

[0759] d) indicates the event ID triggered by the first information (if the update of joint TCI state, DL TCI state, UL TCI state corresponds to different events, if the event ID is indicated, it is not necessary to indicate whether the RS resource is used for joint TCI state, DL TCI state, or UL TCI state. Otherwise, event ID and indication of RS resource for joint TCI state, DL TCI state, or UL TCI state can coexist)

[0760] i. One RS resource can correspond to at least one event ID, i.e. can correspond to one or more event IDs. Refer to the event in another disclosure, for example, the RS resource needs to be used for UL TCI state, or joint TCI state, then needs a high L1-RSRP / L1-SINR, and also needs a small MPE.

[0761] e) Indicate the L1-RSRP corresponding to the reported RS resource

[0762] f) Indicate the L1-SINR corresponding to the reported RS resource

[0763] g) Indicate a reportID or reportconfigID, and the ID corresponds to at least the following

[0764] i. event ID

[0765] ii. threshold, offset, timer, counter, etc. corresponding to the event

[0766] iii. Reference signal resource or reference signal resource set

[0767] iv. Report quality: L1-RSRP or L1-SINR

[0768] 7. Based on 1, the first information is carried in Msg 1 or Msg A (Msg A includes Msg 1 and PUSCH) in a random process

[0769] a) The base station configures the random access resource (including RO (RACH occasion, including time domain and frequency domain resources), preamble) corresponding to the beam report initiation dedicated to the beam report initiation. When the terminal needs to initiate the beam report, it first sends the corresponding preamble on the RO corresponding to the beam report initiation dedicated to the beam report initiation. The random access resource dedicated to the beam report initiation cannot be used for random access initiated by non-beam report (such as traditional random access process, beam failure random access process, etc.).

[0770] i. Further, the base station can also configure different CSI-RS or SSB corresponding to the random access resource RO and preamble dedicated to the beam report initiation. When the terminal determines that the beam quality of a certain SSB or CSI-RS meets the triggering condition, it sends the corresponding preamble on the random access resource RO corresponding to the SSB or CSI-RS dedicated to the beam report initiation.

[0771] 8. Based on 1, the first information is carried in SR

[0772] a) The base station configures SR resource (time-frequency resource and sequence) for SR resource dedicated for beam report initiation, which cannot be used for non-beam report initiation.

[0773] i. Further, the base station can also configure SR resource dedicated for beam report initiation corresponding to different CSI-RS or SSB. The terminal sends SR on the SR resource corresponding to the SSB or CSI-RS when it determines that the beam quality of the SSB or CSI-RS meets the triggering condition.

[0774] 9. Based on 1, the first condition includes the triggering event event configured by the base station or preset by the protocol

[0775] i. The current beam L1-RSRP / L1-SINR is lower than the threshold

[0776] 1. The current beam is defined as:

[0777] a) The beam corresponding to the joint / DL TCI state recently indicated / activated by the base station

[0778] ii. The candidate beam L1-RSRP / L1-SINR is higher than the threshold

[0779] 1. The candidate beam is defined as: the beam corresponding to other TCI states in addition to the MAC CE activated by the joint / DL TCI state recently indicated / activated by the base station / or other TCI states in the RRC configured TCI state list

[0780] iii. The candidate beam L1-RSRP / L1-SINR is higher than the current beam by an offset

[0781] 1. The definition of the current beam and the candidate beam is the same as above

[0782] iv. If the current beam is used for uplink TCI state, the power back off is higher than the threshold

[0783] a) The definition of the current beam is the same as before

[0784] v. If the candidate beam is used for uplink TCI state, the power back off is lower than the threshold

[0785] 1. The definition of the candidate beam is the same as before

[0786] vi. The power back off is lower than the current beam by an offset if the candidate beam is used for uplink TCI state
