[0045] Determining a first resource, where the first resource is used to carry the beam report;

[0046] The beam report is sent based on the first resource.

[0047] In the above embodiment, when the terminal determines that at least one first condition is met, it sends first information, wherein the first condition is used to trigger the terminal to send a beam report, and the first information is used to indicate that the terminal will send a beam report. Furthermore, the terminal also determines a first resource and sends the beam report on the first resource. Therefore, in the method disclosed herein, the terminal triggers the sending of the beam report based on the first condition. Specifically, the sending of the beam report is triggered when the first condition is met, and is not triggered when the first condition is not met. By flexibly setting the first condition, the terminal can report the beam report promptly and accurately at the appropriate time, avoiding situations where the beam reporting interval configured by the network device is too short, resulting in the same optimal beam being reported twice without change, thus wasting signaling, or where the beam reporting interval configured by the network device is too long, potentially resulting in a beam report not being sent when beam quality changes due to the report timing not being reached, thus affecting communication quality. The method disclosed herein can reduce signaling overhead and ensure timely reporting of beam quality changes, thus ensuring communication quality. Moreover, in the above embodiment, the terminal will also determine the first resource for carrying the beam report, so that the terminal can subsequently successfully send the beam report based on the first resource, ensuring the successful sending of the beam report. The network device can then schedule a beam with higher beam quality based on the beam measurement results in the beam report for sending and receiving channels and / or signals, thereby ensuring communication efficiency.

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0338] Optionally, in a communication system, when a terminal sends a beam report to a network device, the network device usually first configures the reporting timing of the beam report to the terminal, and then the terminal reports the beam report based on the reporting timing configured by the network device. Optionally, the network device usually configures the terminal to report the beam report periodically, semi-persistently, or non-periodically. However, in fact, the change in beam quality is what the terminal can learn most promptly, and the reporting timing configured by the network device (such as the period length of periodic reporting or the non-periodic reporting timing) is not necessarily the most appropriate. For example, if the reporting interval is too short, the best beams reported twice may be the same without change, thereby wasting signaling; if the reporting interval is too long, there may be a situation where "when the beam quality changes, it is not reported because the reporting timing has not arrived", thereby affecting the communication quality. At present, it has been proposed to solve the above problems through event-triggered beam reporting. That is, the terminal determines whether the triggering event is met based on its own beam quality. When the triggering event is met, the terminal is triggered to send a beam report, thereby realizing timely and accurate reporting of the beam report and reducing the delay of the beam report. In addition, there is no need for the network equipment to configure the reporting timing of the beam report to the terminal, thereby reducing the signaling overhead.

[0339] At the same time, in some embodiments, when the terminal sends a beam report based on a trigger event, the following two methods are introduced:

[0340] The first type: When the terminal meets the triggering event, the terminal will first send an uplink indication (UL indication) to the network device. 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 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 resource. The network device can reserve the next resource for the beam report in advance so that the terminal can subsequently send a beam report directly on the resource without requesting resources, thereby reducing the delay of the terminal beam report. In addition, when the terminal does not send an uplink indication to the network device, the network device can also use the above-mentioned periodic or semi-persistent resource scheduling configured to the terminal for other transmissions, thereby improving resource utilization.

[0341] The second type: When the terminal meets the triggering event, the terminal will first send an uplink indication (UL indication) to the network device. The uplink indication is used to inform the network device that the terminal will send a beam report. In addition, the uplink indication can also request the network device to configure resources for the beam report. The network device can dynamically configure the resources 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.

[0342] However, currently these two methods are considered to be performed independently, for example, only the first method is executed, or only the second method is executed. This will lead to the following problems:

[0343] 1. For the first method mentioned above, if the terminal does not send an uplink indication and the period of the configured periodic or semi-persistent resource is too short, there may not be enough time in the time interval between the resource and the uplink indication for the network device to schedule the resource for other transmissions, resulting in a waste of resources.

[0344] 2. For the first method mentioned above, if the terminal sends an uplink indication, but the period of the configured periodic or semi-persistent resource is too long, the time interval between the "time point of sending the uplink instruction" and the resource may be too long. At this time, the terminal needs to wait for a long time to send a beam report on the resource, which will increase the delay of the beam report.

[0345] 3. For the first method mentioned above, if the configured periodic or semi-persistent resource is not dedicated to the terminal, for example, it is shared with at least one other terminal, then the two terminals may collide when sending beam reports on the resource. Then the terminal needs to wait for the next periodic resource to send the beam report again, resulting in a longer delay in the beam report.

[0346] 4. For the second method mentioned above, the terminal needs to wait for the scheduling configuration of the network device, which will also increase the delay.

[0347] Based on this, the present disclosure provides a communication method for solving the above technical problems.

[0348] FIG2A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:

[0351] In some embodiments, the first condition may be used to trigger the terminal to send a beam report, wherein when the terminal satisfies the first condition, the terminal may trigger the sending of the beam report.

[0376] Beams other than the beam corresponding to the UL TCI state most recently indicated by the network device;

[0377] The beams in the TCI state list configured by the second signaling except the beam corresponding to the TCI state most recently indicated by the network device;

[0382] Optionally, the above-mentioned second signaling may be, for example, Radio Resource Control (RRC). Optionally, the above-mentioned "beam corresponding to the TCI state most recently indicated by the network device" may include, for example, at least one of the following: the beam corresponding to the joint TCI state most recently indicated by the network device, the beam corresponding to the DL TCI state most recently indicated by the network device, and the beam corresponding to the UL TCI state most recently indicated by the network device.

Optionally, the "TCIstate most recently activated by the network device" may include a unified transmission configuration indication state (unifiedTCIstate) activated by the network device based on a first medium access control layer control element (MACCE), and the unifiedTCIstate will be used for transmission of at least one channel and / or at least one reference signal, including 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). At least two of them. The “TCIstate most recently activated by the network device” may also include the TCIstate of the PDCCH activated by the network device based on the second MACCE and dedicated to the CORESET transmission corresponding to the control resource set (CORESET) ID indicated in the second MACCE.

[0383] Optionally, in some embodiments, when the above-mentioned "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, that is, the beam direction of the first beam is not aimed at the terminal. At this time, the quality of communication based on the first beam may be poor, and communication based on the first beam is not possible.

[0384] Optionally, in other embodiments, when the above-mentioned "beam quality of the second beam is higher than the 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", it indicates that the beam quality of the second beam is higher, that is, the beam direction of the second beam is aimed at the terminal. At this time, the quality of communication based on the second beam may be better, and communication can be switched to the second beam.

[0385] Optionally, in some further embodiments, when the above-mentioned "power backoff value of the first beam is higher than the third threshold value", it indicates that in order to meet the maximum permissible radiation (MPE) of the terminal, the power backoff value of the first beam (that is, the power value that needs to be reduced) is larger, that is, the uplink transmission power in the beam direction of the first beam is smaller, and communication based on the first beam is not possible.

[0386] Optionally, in some further embodiments, when the above-mentioned "the power backoff value of the second beam is lower than the fourth threshold value, or the power backoff value of the second beam is lower than the power backoff value of the first beam by the second offset value", it indicates that in order to meet the MPE of the terminal, the power backoff value of the second beam (that is, the power value that needs to be reduced) is smaller, that is, the uplink transmission power in the beam direction of the second beam is larger, and then communication can be switched to the second beam.

[0387] Optionally, the beam report may include at least one of the following:

[0388] At least one first identifier, optionally, the first identifier may be a resource identifier of a first reference signal resource; the first reference signal resource may be: a reference signal resource that meets a first condition;

[0389] The unified TCI state type recommended by the terminal;

[0390] TCI state corresponding to the first reference signal resource;

[0391] Power headroom corresponding to the first reference signal resource;

[0392] A first indication, where the first indication may 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 may be a protocol agreement and / or a network device configuration;

[0393] a second indication, where the second indication may be used to indicate: when a P-MPR corresponding to the first reference signal resource is greater than a first value, a power backoff value corresponding to the first reference signal resource in order to meet an MPE;

[0394] A third indication, where the third indication may be used to indicate: a maximum number supported by the SRS antenna port corresponding to the first reference signal resource;

[0395] A second identifier, where the second identifier may be a condition identifier (event ID) of the first condition that triggers the terminal to send a beam report;

[0396] beam quality of the first reference signal resource;

[0397] The third identifier (or called reportID or reportconfigID), which can be associated with at least one of the following: a condition identifier, a judgment parameter corresponding to the first condition, a first reference signal resource, a reference signal resource set where the first reference signal resource is located, and a beam quality type to be reported.

[0398] Optionally, the above-mentioned "first reference signal resource is: a reference signal resource that satisfies the first condition" can be understood as, for example: the beam corresponding to the first reference signal resource satisfies the first condition. Optionally, the "beam corresponding to the first reference signal resource" can be, for example: the beam used to transmit the first reference signal resource.

[0399] For example, in some embodiments, the above-mentioned first identifier can be a synchronization signal block identifier (Synchronization Signal Block identify, SSB ID), which can be used to indicate SSB resources; or, the first identifier can be a CSI-RS ID, which can be used to indicate CSI-RS resources.

[0400] It should be noted that, in some embodiments, when the above-mentioned "beam corresponding to the first reference signal resource" is the aforementioned second beam, then the "beam corresponding to the first reference signal resource" can be understood as: the new beam (or target beam) to which the terminal is about to switch. At this time, if the first identifier is an SSB ID, the beam report can further indicate whether the cell corresponding to the SSB ID is the serving cell (serving cell) of the terminal or a non-serving cell (non-serving cell); and, if the cell corresponding to the SSB ID is the non-serving cell of the terminal, the beam report can further indicate the index (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. For example, when the terminal is configured with multiple serving cells, the serving cell index, serving cell index or component carrier ID can be indicated in the beam report.

[0401] Optionally, the aforementioned “Unified TCI state type” may include, for example, a joint TCI state or a separate transmission configuration indication state (Separate Transmission Configuration Indication state, separate TCI state).

[0402] Optionally, the above-mentioned “TCI state corresponding to the first reference signal resource” may include at least one of a joint TCI state, a UL TCI state, and a DL TCI state.

[0403] Optionally, in some embodiments, when the TCI state corresponding to the first reference signal resource is a joint TCI state, if the terminal has indicated in the beam report that the Unified TCI state type recommended by the terminal is a joint TCI state, or if the network device has configured the Unified TCI state type for the terminal as a joint TCI state, and the terminal cannot change the joint TCI state, then the terminal does not need to repeatedly report in the beam report that the TCI state corresponding to the first reference signal resource is a joint TCI state. In other words, in some embodiments, when the terminal does not report in the beam report that the Unified TCI state type recommended by the terminal is a joint TCI state, and / or the unified TCI state type configured by the network device can be changed by the terminal, the terminal reports in the beam report that the TCI state corresponding to the first reference signal resource is a joint TCI state.

[0404] Optionally, in some embodiments, when the TCI state corresponding to the first reference signal resource is the DL TCI state, it may be when the unified TCI state type configured by the network device is the separate TCI state, or, when the terminal does not report the terminal-recommended Unified TCI state type as the separate TCI state in the beam report, or, when the terminal does not report the terminal-recommended Unified TCI state type in the beam report, the terminal reports the TCI state corresponding to the first reference signal resource as the DL TCI state in the beam report.

[0405] Optionally, in some embodiments, when the TCI state corresponding to the first reference signal resource is the UL TCI state, it may be when the unified TCI state type configured by the network device is the separate TCI state, or, when the terminal does not report the terminal-recommended Unified TCI state type as the separate TCI state in the beam report, or, when the terminal does not report the terminal-recommended Unified TCI state type in the beam report, the terminal reports the TCI state corresponding to the first reference signal resource as the UL TCI state in the beam report.

[0406] 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: an identifier of a terminal antenna panel corresponding to the first reference signal resource.

[0407] In addition, in some embodiments, the above-mentioned "power margin, first indication, second indication, and third indication corresponding to the first reference signal resource" may be reported to the network device only when the TCI state corresponding to the first reference signal resource is the UL TCI state. Optionally, the "power margin, first indication, second indication, and third indication corresponding to the first reference signal resource" can be used to inform the network device why the terminal sends the beam report. For example, the beam report may be sent because the MPE of the terminal triggers the first condition, or the beam report may be sent because the terminal needs to switch the antenna panel.

[0408] Optionally, in some embodiments, the above-mentioned "second identifier is a condition identifier of the first condition for triggering the terminal to send a beam report", wherein different first conditions correspond to different condition identifiers. It should be noted that, in some embodiments, the above-mentioned 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, wherein, since "the first condition and the condition identifier have a corresponding relationship", and "the first condition and the TCI state of the reference signal resource have a corresponding relationship", therefore, after knowing the condition identifier, 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.

[0409] For example, assuming that a certain reference signal resource can be used for a UL TCI state or a joint TCI state, two first conditions can be associated with the two TCI states corresponding to the reference signal resource, respectively. Optionally, taking the UL TCI state corresponding to the reference signal resource as an example for illustration, the two first conditions associated with the UL TCI state corresponding to the reference signal resource may include, for example:

[0410] The first event: The beam quality corresponding to the reference signal resource is higher than the first threshold;

[0411] The second event: the power backoff value of the beam corresponding to the reference signal resource is lower than the fourth threshold.

[0412] Based on this, when the reference signal resource meets the first event and the second event, by reporting the condition identifiers of the first event and the second event, it can be implicitly determined that the TCI stat corresponding to the reference signal resource is the UL TCI state.

[0413] Furthermore, in some embodiments, when the aforementioned second identifier implicitly indicates the TCI state corresponding to the first reference signal resource, the beam report need not report the TCI state corresponding to the first reference signal resource, thereby saving resource overhead. However, when the aforementioned second identifier does not 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 beam report may report the TCI state corresponding to the first reference signal resource.

[0414] Optionally, the above-mentioned "beam quality" may include, for example, at least one of the following: Layer 1 Reference Signal Received Power (L1-RSRP), Layer 1 Signal to Interference plus Noise Ratio (L1-SINR), and uplink transmit power.

[0415] Optionally, the aforementioned “determination parameter corresponding to the first condition associated with the third identifier” may include, for example, a threshold, an offset, a timer, a counter, etc. corresponding to the first condition. For example, the determination parameter corresponding to the first condition may be at least one of the aforementioned “first offset, second offset, first threshold, second threshold, third threshold, and fourth threshold.”

[0416] Furthermore, in some embodiments, the above-mentioned "beam" is only an exemplary name of the present disclosure, and it may also be other names. For example, the beam may be called: 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 relationship information (spatialrelationinfo), etc.

[0417] Optionally, the common beam may refer to multiple channels or multiple reference signals using the same beam. In this case, one beam indication signaling may be used to indicate the common beam of multiple channels or multiple reference signals, thereby saving signaling.

[0418] Step 2102: The network device configures a second resource.

[0419] Optionally, the network device may configure the second resource for the terminal, and the terminal may receive the second resource configured by the network device.

[0420] Optionally, the second resource may be used by the terminal to send first information, which may be used by the terminal to inform the network device that the terminal will send a beam report. Optionally, the first information may be sent to the network device when the terminal determines that at least one first condition is satisfied. That is, when the terminal sends the first information, it has not yet sent a beam report to the network device, but is about to send a beam report to the network device.

[0421] Optionally, in some embodiments, different reference signal resources may respectively correspond to second resources, wherein the second resources corresponding to the reference signal resources may be used to send first information on the second resources corresponding to the reference signal resources when the reference signal resources meet at least one first condition. Optionally, the different reference signal resources may include, for example, CSI-RS or SSB. In addition, by making different reference signal resources correspond to second resources, the network device can determine which reference signal resources triggered the sending of the beam report based on the resources used by the terminal when sending the first information. That is, when the network device receives the first information, the terminal has not yet sent the beam report. At this time, the network device already knows which first reference signal resources trigger the beam report. Therefore, when the terminal subsequently sends a beam report to the network device, it no longer needs to report the aforementioned first identifier, thereby saving resource overhead.

[0422] Optionally, in some other embodiments, different first conditions may correspond to second resources, respectively, wherein the second resources corresponding to the first conditions may be used to send the first information on the second resources corresponding to the first condition when the reference signal resource satisfies the first condition. Thus, by making different first conditions correspond to second resources, the network device can determine which first conditions trigger the sending of the beam report based on the resources used by the terminal when sending the first information. That is, when the network device receives the first information, the terminal has not yet sent the beam report. At this time, the network device can already know which first conditions trigger the beam report. Therefore, when the terminal subsequently sends the beam report to the network device, it is no longer necessary to report the aforementioned second identifier. Moreover, when the condition identifier of the first condition (i.e., the second identifier) ​​can implicitly indicate the TCI state corresponding to the reference signal resource, the beam report no longer needs to report the TCI state corresponding to the first reference signal resource, thereby greatly saving resource overhead.

[0423] Optionally, in some embodiments, the second resource may include at least one of the following:

[0424] Random access channel occasion (RO), such as time domain and / or frequency domain resources;

[0425] Scheduling Request (SR) resources, such as time-frequency resources and / or sequences;

[0426] Uplink Control Information (UCI)

[0427] Optionally, the first information may be a preamble carried in Msg 1 or Msg A, or the first information may be carried in PUCCH, or the first information may be carried in SR.

[0428] For example, when the second resource is RO, the first information can be a preamble carried in Msg 1 or Msg A; when the second resource is SR resource, the first information can be carried in SR; when the second resource is UCI, the first information can be carried in PUCCH.

[0429] Furthermore, in some embodiments, the second resource may be dedicated to sending the first information and may not be used to send any information other than the first information. For example, when the second resource is an RO, the RO may not be used for a traditional random access procedure or a random access initiated by a random access procedure due to beam failure.

[0430] Step 2103: The terminal determines at least one first condition.

[0431] For a detailed introduction to the first condition, please refer to the above step description.

[0432] Optionally, in some embodiments, the terminal may determine at least one first condition based on a protocol agreement; in other embodiments, the terminal may receive at least one first condition configured by a network device.

[0433] Step 2104: The terminal determines the second resource.

[0434] For a detailed introduction to the second resource, please refer to the above step description.

[0435] Optionally, in some embodiments, the terminal may determine the second resource based on a protocol agreement; in other embodiments, the terminal may receive the second resource configured by a network device.

[0436] Step 2105: The terminal determines that at least one first condition is met and sends the first information.

[0437] For a detailed introduction to the first condition and the first information, please refer to the above step description.

[0438] Optionally, the terminal may send the first information on a second resource. For a detailed introduction to the second resource, please refer to the above step description.

[0439] Step 2106: The network device sends a first signaling.

[0440] Optionally, in some embodiments, the network device may send the first signaling to the terminal, and the terminal may receive the first signaling. Optionally, the first signaling may be used to schedule a second uplink resource. The first signaling may be, for example, a downlink control indicator (DCI) signaling; and the second uplink resource may be used by the terminal to send a beam report.

[0441] Optionally, in some embodiments, the terminal may be configured with a first uplink resource, which may be a preconfigured periodic uplink resource. The first uplink resource may also be used for the terminal to send a beam report. Specifically, in some embodiments, the resource used for the terminal to send a beam report is typically a first uplink resource. However, in some cases, the first uplink resource may be unavailable to the terminal, or the period of the first uplink resource may be long. In this case, in order to ensure that the terminal can successfully send the beam report in a timely manner, the network device may schedule a second uplink resource to the terminal through the first signaling to send the beam report.

[0442] The following specifically introduces the situation where the network device sends the first signaling.

[0443] Optionally, in some embodiments, for example, after the network device receives the first information, if the first uplink resource after the first information (for example, it can be the first uplink resource immediately after the first information) is reserved for transmission to other terminals other than the terminal (i.e., the terminal that sends the first information), it means that the first uplink resource is not available to the terminal. In order to ensure that the terminal can successfully send a beam report later, the network device can send a first signaling to schedule a second uplink resource, so that the terminal can subsequently send a beam report based on the second uplink resource scheduled by the first signaling. At this time, the first signaling can be located after the first information and before the first uplink resource (for example, before the first uplink resource immediately after the first information). In addition, the second uplink resource scheduled by the first signaling can be located before the first uplink resource or after the first uplink resource, and the present disclosure does not make specific limitations on this.

[0444] Optionally, in some other embodiments, for example, multiple first information are configured within a period of a first uplink resource. That is, before the first uplink resource, there are multiple first information, and only the last first information is closest to the first uplink resource, while the time interval between the previous first information and the first uplink resource is larger. Then, after the network device receives the first information, if the time interval between the first uplink resource after the first information and the time point when the terminal sends the first information is greater than the second value (that is, the first information is not the first information closest to the first uplink resource), it means that it takes a long time to wait for the first uplink resource. At this time, if the terminal still uses the first uplink resource to send a beam report, it will cause a large beam report delay. Therefore, in order to ensure that the terminal can subsequently send a beam report in a timely manner, the network device can send a first signaling to schedule the second uplink resource in a timely manner, so that the terminal can subsequently send a beam report based on the second uplink resource scheduled by the first signaling. At this time, the first signaling is located after the first information, and the first uplink resource is located after the second uplink resource. For example, the first uplink resource immediately after the first information is located after the second uplink resource scheduled by the first signaling.

[0445] Optionally, the first uplink resource and the second uplink resource may each include at least one of the following:

[0446] PUSCH;

[0447] PUCCH.

[0448] Step 2107: The terminal determines the first resource.

[0449] Optionally, the terminal may first determine whether the second condition is met. When the terminal meets the second condition, the terminal may determine the second uplink resource as the first resource; when the terminal does not meet the second condition, the terminal may determine the first uplink resource as the first resource.

[0450] Optionally, in some embodiments, the second condition may include: the terminal corresponds to a first uplink resource and a second uplink resource, and the terminal receives a first signaling sent by the network device, and the first signaling is located after the first information and before the first uplink resource (for example, the first signaling is located before the first uplink resource immediately after the first information).

[0451] Optionally, in some other embodiments, the second condition may include: the terminal corresponds to a first uplink resource and a second uplink resource, and the terminal receives a first signaling sent by the network device, the first signaling is located after the first information, and the first uplink resource is located after the second uplink resource. For example, the first uplink resource immediately after the first information is located after the second uplink resource scheduled by the first signaling.

[0452] For a detailed introduction to the first uplink resource and the second uplink resource, please refer to the above step description.

[0453] It can be seen from the above content that when the terminal determines the first resource for sending the beam report, it can use the above-mentioned "periodic first uplink resource" and "first signaling scheduled second uplink resource" as alternatives for the first resource, so that the terminal can select the most suitable and lowest latency resource from the "periodic first uplink resource" and "first signaling scheduled second uplink resource" as the first resource for carrying the beam report. Therefore, when the terminal subsequently sends the beam report based on the first resource, it not only ensures the successful sending of the beam report, but also ensures the lowest latency of the beam report, thereby greatly reducing the latency of the beam report.

[0454] Step 2108: The terminal sends a beam report based on the first resource.

[0455] Optionally, the terminal may send a beam report on the first resource. For a detailed introduction to the beam report, please refer to the above step description.

[0456] In the above embodiment, when a terminal determines that at least one first condition is met, it sends first information, wherein the first condition is used to trigger the terminal to send a beam report, and the first information is used to indicate that the terminal will send a beam report. Furthermore, the terminal also determines a first resource and sends the beam report on the first resource. Therefore, in the method disclosed herein, the terminal triggers the sending of a beam report based on the first condition. Specifically, the sending of the beam report is triggered when the first condition is met, and is not triggered when the first condition is not met. By flexibly setting the first condition, the terminal can report the beam report promptly and accurately at the appropriate time, avoiding situations where the network device configures a beam report interval that is too short, resulting in two identical optimal beam reports without change, thus wasting signaling, or a network device configures a beam report interval that is too long, potentially preventing the beam report from being performed when beam quality changes due to the report timing not being reached, thus affecting communication quality. The method disclosed herein can reduce signaling overhead and ensure timely reporting of beam quality changes, thus ensuring communication quality. Moreover, in the above embodiment, the terminal will also determine the first resource for carrying the beam report, so that the terminal can subsequently successfully send the beam report based on the first resource, ensuring the successful sending of the beam report.

[0610] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0611] Figure 5 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 5, the embodiment of the present disclosure relates to a communication method for a communication system including a terminal and a network device. The method includes at least one of the following:

[0612] Step 5101: The terminal determines that at least one first condition is satisfied and sends first information.

[0613] Step 5102: The network device receives the first information.

[0614] Step 5103: The terminal determines the first resource.

[0615] Step 5104: The terminal sends the beam report based on the first resource.

[0616] Step 5105: The network device receives the beam report sent by the terminal on the first resource.

[0617] Optional implementations of steps 5101 to 5105 can be found in the above embodiments.

[0618] In some embodiments, the above method may include the method described in the above embodiments of the communication system side, the first device side, the network device side, etc., which will not be repeated here.

[0619] The communication method involved in the embodiment of the present disclosure may include at least one of steps 5101 to 5105. For example, step 5101 may be implemented as an independent embodiment, and step 5102 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0620] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0621] The following is an exemplary introduction to the above method.

[0622] 1. In response to a first condition being met, the terminal sends first information for initiating a beam report carried on the PUSCH / PUCCH.

[0623] a) The beam can be called 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.

[0624] 2. According to 1, the PUSCH / PUCCH includes at least one of the following

[0625] a) Periodic first PUSCH / PUCCH resource

[0626] b) The second PUSCH / PUCCH resource scheduled by DCI, where DCI follows the first information

[0627] 3. Based on 2, when both a periodic first PUSCH / PUCCH resource and a DCI-scheduled second PUSCH / PUCCH resource exist, how is it determined whether to send a beam report on the first resource or the second resource?

[0628] a) If the DCI corresponding to the second PUSCH / PUCCH resource is before the time t0 of the first PUSCH / PUCCH resource, and t0 is non-negative, the second PUSCH / PUCCH has a higher priority;

[0629] i. In this case, the first PUSCH / PUCCH resource may be shared with other UEs, but the other UEs have already sent UL indications to the NW in advance and have reserved the first PUSCH / PUCCH resource. Therefore, the NW can only dynamically allocate the second PUSCH / PUCCH resource to the UE.

[0630] b) If the second PUSCH / PUCCH resource is t1 before the first PUSCH / PUCCH resource, and t1 is non-negative, the second PUSCH / PUCCH has a higher priority

[0631] i. This situation corresponds to a longer period of the first PUSCH / PUCCH resource. For example, the period of the first PUSCH / PUCCH resource is a multiple of the first message. In this case, only one first message is followed by a first PUSCH / PUCCH resource within a period, while other first messages are not followed by a first PUSCH / PUCCH resource. To reduce latency, the network network can schedule a second PUSCH / PUCCH resource for the terminal using DCI.

[0632] c) In other cases, the first PUSCH / PUCCH resource has a higher priority.

[0633] 4. According to 1, the beam report includes at least one of the following:

[0634] a) The ID of at least one reference signal resource used to determine the new beam

[0635] i.SSB ID

[0636] 1. Indicates whether it corresponds to a serving cell or a non-serving cell; if it is a non-serving cell, indicates the index of the non-serving cell in the additional PCI list

[0637] ii. CSI-RS ID

[0638] b) Indicates the unified TCI state type used: joint TCI state or separate TCI state

[0639] c) indicating that at least one reference signal resource reported is used for

[0640] i. Joint TCI state (This is not required if the terminal has indicated that the unified TCI state type is joint in b, or the base station has configured the unified TCI state type as joint and the terminal cannot change it. In other words, if there is no b, and the unified TCI state type configured by the base station can be changed by the terminal, then this can be included in the beam report)

[0641] ii. Or for DL ​​TCI state (needed only when the base station configures the unified TCI state type as separate or the terminal indicates the unified TCI state type as separate in b) or b is not present)

[0642] iii. Or for UL TCI state (required or not required only when the base station configures the unified TCI state type as separate or the terminal indicates the unified TCI state type as separate in b). The following is dedicated to when reference signal resources are used in UL TCI state, mainly to inform why the new beam needs to be updated, such as due to MPE or due to panel switching.

[0643] 1. Power head room corresponding to reference signal resources

[0644] 2. P: To meet MPE, is the P-MPR corresponding to the reference signal resource lower than P-MPR_00 (the value of P-MPR_00 specified by the base station configuration or protocol)?

[0645] 3.MPE: If P is greater than P-MPR_00, then MPE indicates the power backoff value corresponding to the reference signal resource

[0646] 4. The maximum supported number of SRS antenna ports corresponding to the reference signal resource

[0647] a) Equivalent to the terminal panel identifier corresponding to the reference signal resource

[0648] d) Indicates the Event ID corresponding to the triggering first information (if the updates of the joint TCI state, DL TCI state, and UL TCI state correspond to different events, then indicating the event ID eliminates the need to indicate whether the RS resource is used for the joint TCI state, DL TCI state, or UL TCI state. Otherwise, the event ID and the indication of whether the RS resource is used for the joint TCI state, DL TCI state, or UL TCI state can coexist)

[0649] i. An RS resource can correspond to at least one event ID, meaning it can correspond to one or more event IDs. Referring to the event in another document, if the RS resource is used in the UL TCI state or the joint TCI state, a high L1-RSRP / L1-SINR and a low MPE are required.

[0650] e) Indicates the L1-RSRP corresponding to a reported RS resource

[0651] f) Indicates the L1-SINR corresponding to a reported RS resource

[0652] g) Indicates a reportID or reportconfigID, which is associated with at least one of the following:

[0653] i.event ID

[0654] ii. Event corresponding threshold, offset, timer, counter, etc.

[0655] iii. Reference signal resource or reference signal resource set

[0656] iv.Report quality: L1-RSRP or L1-SINR

[0657] 5. Based on 1, the first information is carried in Msg 1 or Msg A in the random process (Msg A includes Msg 1 and PUSCH)

[0658] a) The base station configures random access resources dedicated to beam report initiation, including RO (RACH occasion, including time and frequency domain resources) and preamble. When a terminal needs to initiate a beam report, it first sends the corresponding preamble on the RO dedicated to beam report initiation. Random access resources dedicated to beam report initiation cannot be used for random access initiated by non-beam reports (such as traditional random access procedures and beam failure random access procedures).

[0659] i. Furthermore, the base station can also configure different CSI-RS or SSB-specific random access resources (ROs) and preambles for 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.

[0660] 6. Based on 1, the first information is carried in SR

[0661] a) The base station configures SR resources (time-frequency resources and sequences). The SR resources are dedicated to beam report initiation and cannot be used for non-beam report initiation.

[0662] i. Furthermore, the base station can also configure SR resources dedicated to beam reporting initiation corresponding to different CSI-RS or SSBs. When the terminal determines that the beam quality of a certain SSB or CSI-RS meets the triggering conditions, it sends an SR on the SR resource corresponding to that SSB or CSI-RS.

[0663] 7. Based on 1, the first condition includes a trigger event configured by the base station or preset by the protocol

[0664] i. The current beam L1-RSRP / L1-SINR is lower than the threshold

[0665] 1. The current beam is defined as:

[0666] a) The best beam in the last beam report, or the beam corresponding to the joint / DL TCI state recently indicated / activated by the base station, or all beams in the last beam report, or the worst beam in the beam report

[0667] ii. The candidate beam L1-RSRP / L1-SINR is higher than the threshold

[0668] 1. Candidate beams are defined as: non-optimal beams in the last beam report, beams other than those included in the last beam report, or beams other than the joint / DL TCI state most recently indicated / activated by the base station

[0669] iii. The candidate beam L1-RSRP / L1-SINR is one offset higher than the current beam

[0670] 1. The definitions of current beam and candidate beam are the same as above

[0671] iv. If the current beam is used in uplink TCI state, the power back off is higher than the threshold

[0672] a) The current beam definition is the same as before

[0673] v. If the candidate beam is used in the uplink TCI state, the power back off is lower than the threshold

[0674] 1. The candidate beam is defined as before

[0675] If the candidate beam is used in the uplink TCI state, the power back off is one offset lower than the current beam.

[0676] The definitions of current beam and candidate beam are the same as above.

[0677] This method reduces the delay of beam reporting and improves resource efficiency by proposing a method of combining preconfigured uplink resources and dynamically scheduled uplink resources, and determines the priority between these two resources to enable the terminal to correctly select the resources for beam reporting.
