[0036] This disclosure provides embodiments of a communication method, a communication device, a communication system, and a storage medium.

[0037] In a first aspect, embodiments of this disclosure provide a communication method executed by a terminal, the method comprising:

[0038] One or more first reference signal resources are determined, the first reference signal resources being determined based on the indicated TCI state;

[0039] If the first reference signal resource satisfies the first event, a first report corresponding to the first reference signal resource is sent.

[0040] In the above embodiments, the terminal can determine one or more first reference signal resources based on the indicated Transmission Configuration Indication state (indicated TCI state), and when the first reference signal resource satisfies a first event, the terminal will send a first report corresponding to the first reference signal resource. Therefore, the embodiments of this disclosure can clearly determine the first reference signal resource used to trigger the first report, thereby facilitating the successful transmission of the first report. Furthermore, in the method of the embodiments of this disclosure, the first reference signal resource is determined based on the indicated TCI state; therefore, the first reference signal resource determined by the terminal will be related to the terminal's transmission configuration (such as the beam quality of the terminal's current beam). Thus, when the first report is triggered based on the first reference signal resource, the accuracy of the first report can be ensured. Meanwhile, in this embodiment of the disclosure, the terminal triggers the sending of the first report based on a first event. By flexibly setting the first event, the terminal can send the first report in a timely and accurate manner at the appropriate time, avoiding situations where "the reporting interval configured by the network device is too short, resulting in the content of two reports being the same without change, thus wasting signaling, or the reporting interval configured by the network device is too long, which may result in the terminal not reporting when the transmission configuration changes because the reporting time has not yet arrived, thus affecting communication quality." Therefore, the method of this embodiment of the disclosure can reduce signaling overhead and also ensure timely reporting when beam quality changes, thus guaranteeing communication quality.

[0041] In conjunction with some embodiments of the first aspect, in some embodiments, the indicated TCI state is used for at least one of the following:

[0042] Physical downlink control channel (PDCCH) transmission;

Thus, including the measurement value of the first reference signal resource in the first report ensures the accuracy and validity of the first report. Furthermore, after receiving the first report from the terminal, the network device can determine the beam quality of the terminal's current beam based on the first report. When the beam quality of the terminal's current beam is low, the device can schedule the terminal to use other beams with better beam quality for communication, thereby ensuring the terminal's communication performance.

[0120] In the above embodiments, it is explained how the terminal determines the first reference signal resource based on the indicated TCI state, and the specific content included in the first report when the type of the first reference signal resource is different. This makes it easier for the terminal to accurately determine the first reference signal resource and accurately send the first report, ensuring the accuracy and effectiveness of the first report and guaranteeing communication performance.

[0121] In conjunction with some embodiments of the first aspect, in some embodiments, the CSI-RS measurements and SSB measurements in the first report are arranged according to a first rule; the first rule includes: the CSI-RS measurements are located before the SSB measurements, or the SSB measurements are located before the CSI-RS measurements.

[0122] Wherein, the first rule is agreed upon by the protocol, and / or the first rule is configured by the network device.

[0123] In the above embodiments, the arrangement rules between the CSI-RS measurement values ​​and the SSB measurement values ​​in the first report are explained. Thus, the terminal and network device can have a unified understanding of the "arrangement rules between the CSI-RS measurement values ​​and the SSB measurement values ​​in the first report". Therefore, the first report can include only the CSI-RS measurement values ​​and the SSB measurement values, and does not need to include other explanatory content. Furthermore, the network device can accurately determine which measurement values ​​in the first report correspond to CSI-RS and which measurement values ​​correspond to SSB based on the arrangement rules, thereby saving the communication resources required for the first report and reducing communication overhead.

Furthermore, the first report can include the measurement value and / or ID of at least one first reference signal resource that satisfies the first event, ensuring the accuracy and validity of the first report.

[0128] The measured value of the first reference signal resource is lower than the first threshold value;

[0129] The sum of the measured value of the first reference signal resource and the first offset value is lower than the second threshold value.

This achieves successful measurement of the first reference signal and successful transmission of the first report, enabling the network device to schedule the terminal's communication beam based on the first report, thus ensuring communication quality.

The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0423] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0425] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0426] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0427] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), 6th generation mobile communication system (6G), 6G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future Generation Radio Access (FX), Global System for Mobile Communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), and IEEE 802.16 (WiMAX, a registered trademark), IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0428] Optionally, to ensure beam-based communication quality, terminals typically perform beam measurements and report beam reports to the network device based on the measurement results. This allows the network device to schedule higher-quality beams for channel and / or signal transmission and reception based on the beam measurement results in the beam report, thereby improving communication efficiency. Optionally, in a communication system, when a terminal sends a beam report to the network device, the network device typically configures the reporting timing for the beam report to the terminal first, and then the terminal reports the beam report based on the timing configured by the network device. Optionally, the network device typically configures the terminal to report beam reports periodically, semi-persistently, or non-periodically. However, in reality, changes in beam quality are what terminals are most aware of in a timely manner, and the reporting timing configured by the network device (such as the period length for periodic reporting or the timing for non-periodic reporting) may not be the most appropriate. For example, if the reporting interval is too short, the optimal beam in two reports may be the same, resulting in no change and wasted signaling. If the reporting interval is too long, a situation may arise where "when the beam quality changes, it is not reported because the reporting time has not yet arrived," thus affecting communication quality. Currently, an event-triggered beam reporting method has been proposed to solve the above problems. That is, the terminal measures the reference signal corresponding to the current beam (or serving beam). If the measured value of the reference signal corresponding to the current beam meets the trigger event, the terminal sends a beam report. This achieves timely and accurate beam reporting, reduces beam reporting latency, and eliminates the need for network equipment to configure the beam reporting timing for the terminal, thereby reducing signaling overhead.

[0429] Optionally, in some embodiments, the terminal can typically determine the reference signal corresponding to the current beam based on the indicated transmission configuration indication state (indicated TCI state). However, how the terminal specifically determines the reference signal corresponding to the current beam based on the indicated TCI state is a problem that needs to be solved.

[0430] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, this embodiment of the disclosure relates to a communication method for a communication system 100; the method includes:

[0431] Step 2101: The network device sends the indicated TCI state to the terminal.

[0439] Sounding reference signal (SRS) transmission.

[0440] Optionally, the indicated TCI state may include a Unified Transmission Configuration Indication state (unified TCI state). In some embodiments, the indicated TCI state can be used for both uplink and downlink transmissions simultaneously. In this case, the indicated TCI state can be used for at least two of PDCCH, PDSCH, PUCCH, PUSCH, DMRS, CSI-RS, and SRS transmissions. For example, the indicated TCI state can be used for both PDCCH and PUCCH transmissions, or it can be used for both PDSCH and PUSCH transmissions.

[0441] Optionally, indicatedTCIstate includes at least one of joint Transmission Configuration Indication state (jointTCIstate), TCIstate, Down Link Transmission Configuration Indication state (DLTCIstate), and Up Link Transmission Configuration Indication state (ULTCIstate).

[0442] Optionally, in some embodiments, the indicated TCI state can be used to indicate one or more reference signal resources. For example, in some embodiments, the indicated TCI state can be used to indicate two different CSI-RSs, which may include a CSI-RS corresponding to quasi-colocation type (QCL Type) A and a CSI-RS corresponding to QCL Type D. Optionally, the resource set associated with the CSI-RS corresponding to QCL Type A is configured to track reference signal information (trs-info), and the resource set associated with the CSI-RS corresponding to QCL Type D is configured to repetition. In other embodiments, the indicated TCI state can be used to indicate a CSI-RS associated with both QCL Type A and QCL Type D, and the resource set associated with this CSI-RS is configured to track reference signal information. In some other embodiments, the indicated TCI state can be used to indicate a CSI-RS associated with QCL Type A and QCL Type D, the CSI-RS being associated with two resource sets configured to track reference signal information and repeat, wherein one of the resource sets associated with the CSI-RS is configured to track reference signal information and the other resource set associated with the CSI-RS is configured to repeat.

[0444] Optionally, in some embodiments, the first reference signal resource can be the reference signal resource corresponding to the terminal's current beam (or: serving beam, current beam, etc.). The first reference signal resource can be used to trigger the sending of a first report. For example, when the first reference signal resource meets a first event, the terminal can be triggered to send a first report. The first report can be, for example, a beam report of the beam corresponding to the first reference signal resource.

[0450] Optionally, in some embodiments, when the first reference signal resource satisfies the first event described above, it indicates that the quality of the terminal's current beam is poor. In this case, the terminal needs to send a first report to the network device so that the network device can schedule a better quality communication beam for the terminal based on the first report, thereby ensuring the communication quality of the terminal.

Optionally, the fourth reference signal resource may be an SSB, and the fourth reference resource may be the QCL source of the CSI-RS indicated by the indicated TCI state.

[0456] In some embodiments, when the indicated TCI state indicates a CSI-RS and the resource set associated with that CSI-RS is configured to track reference signal information and repeat, the network device may identify the fourth reference signal resource and the CSI-RS indicated by the indicated TCI state as the first reference signal resource.

[0479] Optionally, in some embodiments, when the indicated TCI state indicates the CSI-RS corresponding to QCL Type A and the CSI-RS corresponding to QCL Type D, the terminal can determine the CSI-RS corresponding to QCL Type D as the first reference signal resource, and / or, the terminal can receive the first signaling and determine the first reference signal resource based on the first signaling. For a detailed description of this part, please refer to the steps described above.

[0480] Optionally, in some embodiments, when the indicated TCI state indicates the CSI-RS corresponding to QCL Type A and the CSI-RS corresponding to QCL Type D, the terminal can determine the second reference signal resource and the CSI-RS corresponding to QCL Type D as the first reference signal resource respectively to obtain two first reference signal resources, and / or, the terminal can receive the second signaling and determine the first reference signal resource based on the second signaling.

[0484] Optionally, in some embodiments, when the indicated TCI state indicates a CSI-RS, and the resource set associated with that CSI-RS is configured to track reference signal information and repeat, the terminal may determine the fourth reference signal resource and the CSI-RS indicated by the indicated TCI state as the first reference signal resource, and / or, the terminal may receive a sixth signaling and determine the first reference signal resource based on the sixth signaling.

[0485] Step 2106: The first reference signal resource satisfies the first event, and the terminal sends the first report corresponding to the first reference signal resource.

[0486] For a detailed description of the first event, please refer to step 2102 above.

[0487] Optionally, the first report may include at least one of the following:

For example, when the first report contains measurements corresponding to two first reference signal resources, the second indication information may only indicate the type of the first reference signal resource corresponding to the first measurement value, while the type of the first reference signal resource corresponding to the other measurement value is different from the type of the first measurement value.

[0495] Optionally, in some embodiments, when at least one first reference signal resource satisfies a first event, the terminal sends a first report corresponding to the first reference signal resource, wherein the first report may include the measurement value and / or ID of at least one first reference signal resource that satisfies the first event.

[0496] For example, when the indicated TCI state indicates the CSI-RS corresponding to QCL Type A and the CSI-RS corresponding to QCL Type D, the terminal may send a first report corresponding to the first reference signal resource when at least one of the second reference signal resource and the CSI-RS corresponding to QCL Type D satisfies the first event. In other embodiments, when the indicated TCI state indicates a CSI-RS and the resource set associated with that CSI-RS is configured to track reference signal information, the terminal may send a first report corresponding to the first reference signal resource when the third reference signal resource satisfies the first event. In still other embodiments, when the indicated TCI state indicates a CSI-RS and the resource set associated with that CSI-RS is configured to track reference signal information and repeat, the terminal may send a first report corresponding to the first reference signal resource when at least one of the fourth reference signal resource and the CSI-RS indicated by the indicated TCI state satisfies the first event.

[0497] In some embodiments, the content included in the first report may differ when the type of the first reference signal resource is different.

[0498] Optionally, in some embodiments, when the first reference signal resource includes a CSI-RS corresponding to QCLType D, the first report may include at least one of the following: the CSI-RS ID of the CSI-RS corresponding to QCLType D, the measured value of the CSI-RS corresponding to QCLType D, and first indication information.

[0499] For example, in some embodiments, the first report may include the CSI-RS measurement value corresponding to QCLType D; or, the first report may include first indication information and the CSI-RS measurement value corresponding to QCLType D. Alternatively, the first report may include the CSI-RS measurement value corresponding to QCLType D and the CSI-RS ID corresponding to QCLType D. Or, the first report may include first indication information, the CSI-RS measurement value corresponding to QCLType D, and the CSI-RS ID corresponding to QCLType D.

[0500] Optionally, in some embodiments, when the first reference signal resource includes the second reference signal resource and the CSI-RS corresponding to QCLType D, the first report may include at least one of the following: the CSI-RS ID of the CSI-RS corresponding to QCLType D, the measurement value of the CSI-RS corresponding to QCLType D, the SSB ID of the SSB, the measurement value of the SSB, first indication information, and second indication information.

[0501] For example, in some embodiments, the first report may include the CSI-RS measurement value and the SSB measurement value corresponding to QCLType D; or, the first report may include first indication information, second indication information, the SSB measurement value, and the CSI-RS measurement value corresponding to QCLType D. Alternatively, the first report may include first indication information, the SSB measurement value, and the CSI-RS measurement value corresponding to QCLType D. Alternatively, the first report may include second indication information, the SSB measurement value, and the CSI-RS measurement value corresponding to QCLType D.

[0503] For example, in some embodiments, the first report may include the measured value of the SSB, or the first report may include first indication information and the measured value of the SSB. Alternatively, the first report may include the measured value of the SSB and the SSB ID. Or, the first report may include first indication information, the measured value of the SSB, and the SSB ID.

[0504] Optionally, in some embodiments, when the first reference signal resource includes a CSI-RS indicated by an indicated TCI state, the first report may include at least one of the following: a CSI-RS ID indicated by an indicated TCI state, a measurement value of the CSI-RS indicated by an indicated TCI state, and first indication information, which may be used to indicate that the type of the first reference signal resource is CSI-RS.

[0505] For example, in some embodiments, the first report may include the CSI-RS measurement value indicated by the indicated TCI state; or, the first report may include first indication information and the CSI-RS measurement value indicated by the indicated TCI state. Alternatively, the first report may include the CSI-RS measurement value indicated by the indicated TCI state and the CSI-RS ID indicated by the indicated TCI state. Or, the first report may include first indication information, the CSI-RS measurement value indicated by the indicated TCI state, and the CSI-RS ID indicated by the indicated TCI state.

[0506] Optionally, in some embodiments, when the first reference signal resource includes the fourth reference signal resource, the first report may include at least one of the SSB ID of the SSB, the measured value of the SSB, and first indication information, which may be used to indicate that the type of the first reference signal resource is SSB.

[0507] For example, in some embodiments, the first report may include the measured value of the SSB, or the first report may include first indication information and the measured value of the SSB. Alternatively, the first report may include the measured value of the SSB and the SSB ID. Or, the first report may include first indication information, the measured value of the SSB, and the SSB ID.

[0508] Optionally, in some embodiments, when the first reference signal resource includes a fourth reference signal resource and a CSI-RS indicated by a TCI state, the first report may include at least one of the following: the CSI-RS ID of the CSI-RS indicated by the TCI state, the measurement value of the CSI-RS indicated by the TCI state, the SSB ID of the SSB, the measurement value of the SSB, first indication information, and second indication information. The first indication information may be used to indicate that the type of the first reference signal resource includes CSI-RS or SSB. Optionally, the second indication information is used to indicate at least one of the following: the type of at least one of the two first reference signal resources, or the types of the two first reference signal resources are different.

[0509] For example, in some embodiments, the first report may include the CSI-RS measurement value indicated by the TCI state and the SSB measurement value; or, the first report may include first indication information, second indication information, the SSB measurement value, and the CSI-RS measurement value indicated by the TCI state. Alternatively, the first report may include first indication information, the SSB measurement value, and the CSI-RS measurement value indicated by the TCI state. Alternatively, the first report may include second indication information, the SSB measurement value, and the CSI-RS measurement value indicated by the TCI state. Alternatively, the first report may include the CSI-RS measurement value indicated by the TCI state, the CSI-RS ID of the CSI-RS indicated by the TCI state, the SSB ID of the SSB, and the SSB measurement value. Alternatively, the first report may include first indication information, second indication information, the CSI-RS measurement value indicated by the TCI state, the CSI-RS ID of the CSI-RS indicated by the TCI state, the SSB ID of the SSB, and the SSB measurement value.

[0510] It should be noted that in some embodiments, the terminal and network device can have a unified understanding of "which reference signal resources the first reference signal resource includes and / or what the first report includes." For example, the terminal and network device can uniformly understand that the first reference signal resource includes the CSI-RS corresponding to QCLType D, and the first report includes the measured value of the CSI-RS corresponding to QCLType D. Alternatively, the terminal and network device can uniformly understand that the first reference signal resource includes the CSI-RS corresponding to QCLType D, and the first report includes the first indication information and the measured value of the CSI-RS corresponding to QCLType D. This ensures that the network device accurately determines the beam quality of the terminal based on the first report, so that the network device can accurately perform beam scheduling on the terminal, thus guaranteeing the communication quality between the terminal and the network device.

[0511] Optionally, in some embodiments, the CSI-RS measurement value and the SSB measurement value in the first report can be arranged according to a first rule; optionally, the first rule may include: the CSI-RS measurement value precedes the SSB measurement value, or the SSB measurement value precedes the CSI-RS measurement value. In some embodiments, the first rule may be agreed upon by a protocol, and / or the first rule may be configured by a network device.

[0512] For example, in some embodiments, when the first report includes CSI-RS measurements and SSB measurements, but not CSI-RS ID and SSB ID, the terminal can arrange the CSI-RS and SSB measurements in the first report based on a pre-agreed and / or pre-configured first rule. This allows the network device, upon receiving the first report, to accurately determine which measurements correspond to CSI-RS and which correspond to SSB based on the first rule. This ensures that the terminal and network device have a unified understanding of the "arrangement rule for CSI-RS and SSB measurements in the first report," guaranteeing the accuracy of the first report. Furthermore, it eliminates the need to include at least one of the CSI-RS ID, SSB ID, first indication information, or second indication information in the first report to distinguish between CSI-RS and SSB measurements, thus saving communication resources required for the first report and reducing communication overhead.

[0513] Step 2107: The network device performs beam scheduling based on the first report.

[0514] Optionally, the network device can determine the beam quality of the terminal's current beam based on the measurement values ​​of the first reference signal resource in the first report (such as the measurement values ​​of CSI-RS and / or SSB). When the beam quality of the terminal's current beam is poor, the network device can schedule a beam with better quality for the terminal to communicate, thereby ensuring the communication quality of the terminal.

[0515] In summary, in the above embodiments, the terminal can determine one or more first reference signal resources based on the indicated Transmission Configuration Indication state (indicated TCI state), and when the first reference signal resource satisfies a first event, the terminal will send a first report corresponding to the first reference signal resource. Therefore, the embodiments of this disclosure can clearly determine the first reference signal resource used to trigger the first report, thereby facilitating the successful transmission of the first report. Furthermore, in the method of the embodiments of this disclosure, the first reference signal resource is determined based on the indicated TCI state; therefore, the first reference signal resource determined by the terminal will be related to the terminal's transmission configuration (such as the beam quality of the terminal's current beam). Thus, when the first report is triggered based on the first reference signal resource, the accuracy of the first report can be ensured. Meanwhile, in this embodiment of the disclosure, the terminal triggers the sending of the first report based on a first event. By flexibly setting the first event, the terminal can send the first report in a timely and accurate manner at the appropriate time, avoiding situations where "the reporting interval configured by the network device is too short, resulting in the content of two reports being the same without change, thus wasting signaling, or the reporting interval configured by the network device is too long, which may result in the terminal not reporting when the transmission configuration changes because the reporting time has not yet arrived, thus affecting communication quality." Therefore, the method of this embodiment of the disclosure can reduce signaling overhead and also ensure timely reporting when beam quality changes, thus guaranteeing communication quality.

[0516] The communication method involved in the embodiments of this disclosure may include at least one of steps 2101 to 2107. For example, step 2101 may be implemented as a separate embodiment, step 2102 may be implemented as a separate embodiment, step 2103 may be implemented as a separate embodiment, and step 2101+S2102 may be implemented as a separate embodiment, but is not limited thereto.

[0517] In this implementation or embodiment, unless there is contradiction, each step can be independent, arbitrarily combined or exchanged in order, optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementations or other embodiments.

[0694] In this implementation or embodiment, unless there is contradiction, each step can be independent, arbitrarily combined or exchanged in order, optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementations or other embodiments.

[0695] Figure 5 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 5, the present disclosure relates to a communication method for a communication system, which includes a network device and a terminal. The method includes at least one of the following:

[0696] Step 5101: The terminal determines one or more first reference signal resources.

[0697] Step 5102: When the first reference signal resource satisfies the first event, the terminal sends the first report corresponding to the first reference signal resource to the network device.

[0698] The optional implementation methods of steps 5101-5102 can be found in the above embodiments.

[0699] In some embodiments, the above methods may include the methods described in the embodiments on the communication system side, terminal side, network device side, etc., which will not be repeated here.

[0700] The communication method involved in the embodiments of this disclosure may include at least one of steps 5101 to 5102. For example, step 5101 may be implemented as a separate embodiment, and step 5102 may be implemented as a separate embodiment, but are not limited thereto.

[0701] In this implementation or embodiment, unless there is contradiction, each step can be independent, arbitrarily combined or exchanged in order, optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementations or other embodiments.

[0702] The following is an exemplary description of the above method.

[0703] In NR, especially in communication bands above frequency range 2 (6GHz), high-frequency channels attenuate rapidly. To ensure coverage, beam-based transmission and reception are required. Current considerations involve configuring base stations with periodic, semi-persistent, or non-periodic beam measurement reports.

[0704] However, changes in beam quality are actually the most timely information that terminals can perceive. The length of the reporting period configured by the base station, or the timing of non-periodic reporting, may not be optimal. With a period that is too short, the optimal K beams might be reported twice with little variation, wasting signaling. With a period that is too long, beam changes might occur before the reporting time, impacting communication quality. Similarly, with non-periodic reporting, the base station might trigger terminal reporting too early or too late, which is not the most suitable timing.

[0705] Related technologies propose determining the current beam based on the indicated TCI state. However, the RS included in the indicated TCI state may fall into two categories: one is the same CSI-RS configured with TRS for both Type A and Type D; the other is a CSI-RS configured with TRS for Type A and a CSI-RS configured with repetition for Type D. Currently, for the first case, where both are configured with TRS and are the same CSI-RS, determining the RS corresponding to the current beam based on this CSI-RS is a problem that needs to be solved, because traditional CSI-RS configured with TRS cannot be used for beam measurement.

[0706] 'typeA':{Doppler shift,Doppler spread,average delay,delay spread}

[0707] 'typeD':{Spatial Rx parameter}.

[0708] This disclosure proposes that in UE-initiated or event-triggered beam reporting, the terminal determines the serving beam, and when the quality of the serving beam is lower than a threshold, reports the beam report corresponding to the serving beam, thereby ensuring the reliability of the triggered event.

[0709] 1. The terminal determines the first reference signal resource. The first reference signal resource is determined based on the terminal's indicated TCI state. When the L1-RSRP / L1-SINR of the first reference signal resource (hereinafter, L1-RSRP will be used as an example) meets the first event, the terminal reports the beam report corresponding to the first reference signal resource.

[0710] 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, indicated TCI state, joint TCI state, DL TCI state, UL TCI state, unified TCI state, common TCI state, spatialrelationinfo, etc.

[0711] b) The indicated TCI state can be used for the transmission of at least two of PDCCH, PDSCH, PUCCH, PUSCH, DMRS, CSI-RS, and SRS.

[0712] 2. Based on 1, the beam report includes at least one of the following:

[0713] a) CSI-RS resource ID;

[0714] b) SSB ID;

[0715] c) The L1-RSRP corresponding to the CSI-RS resource ID;

[0716] d) L1-RSRP corresponding to SSB ID;

[0717] e) A 1-bit indicator field indicates the type of RS, which may be SSB or CSI-RS.

[0718] 3. Based on 2, beam reports include the following multiple scenarios.

[0719] a) Beam Reporting only includes L1-RSRP. That is, in this case, the RS base station and terminal corresponding to the indicated TCI state for serving beam or current beam have a consistent understanding, which also includes any of the following cases.

[0720] i.Case 1: The indicated TCI state indicates two CSI-RS IDs, that is, the CSI-RS ID corresponding to QCL Type A and the CSI-RS ID corresponding to QCL Type D are different. Therefore, the RS used for measuring the serving beam or current beam is the CSI-RS ID corresponding to QCL Type D. So the beam report only contains L1-RSRP, which tells the base station that it contains the L1-RSRP corresponding to the CSI-RS ID corresponding to QCL Type D.

[0721] 1. Alternatively, explicit signaling, RRC / MAC CE / DCI indicates that the RS corresponding to the service beam is CSI-RS.

[0722] ii.Case 2: The indicated TCI state indicates a CSI-RS ID, that is, the CSI-RS ID corresponding to QCL Type A indicated by the indicated TCI state is the same as the CSI-RS ID corresponding to QCL Type D, and the resource set associated with this CSI-RS resource ID is configured with trs-info. Then the RS used for serving beam or current beam measurement is the SSB of the QCL source of this CSI-RS ID. Therefore, the beam report only contains L1-RSRP, which tells the base station that it contains the L1-RSRP corresponding to this SSB.

[0723] 1. Alternatively, explicit signaling, RRC / MAC CE / DCI indicates that the RS corresponding to the service beam is SSB.

[0724] b) The beam report includes the CSI-RS ID and L1-RSRP.

[0725] i. For example, Case 1 mentioned above.

[0726] ii. or Case 3: The indicated TCI state indicates a CSI-RS ID, that is, the CSI-RS ID corresponding to QCL Type A indicated by the indicated TCI state is the same as the CSI-RS ID corresponding to QCL Type D, and the resource set associated with this CSI-RS resource ID is configured with trs-info, and the other associated resource set is configured with repetition.

[0727] 1. The RS used for service beam or current beam measurement can be the CSI-RS ID, so the beam report includes the CSI-RS ID and L1-RSRP.

[0728] a) Or explicit signaling, RRC / MAC CE / DCI indicates that the RS corresponding to the service beam is CSI-RS.

[0729] 2. Since the RS used for serving beam or current beam measurements can be either a CSI-RS ID or the SSB of the QCL source of that CSI-RS ID, the beam report here does not need to directly indicate the CSI-RS ID. Only a 1-bit indicator field is needed to indicate whether the RS type is CSI-RS (with repetition configured) or SSB.

[0730] c) The beam report includes the SSB ID and L1-RSRP.

[0731] i. For example, case 2 above.

[0732] ii. or Case 3: The indicated TCI state indicates a CSI-RS ID, that is, the CSI-RS ID corresponding to QCL Type A indicated by the indicated TCI state is the same as the CSI-RS ID corresponding to QCL Type D, and the resource set associated with this CSI-RS resource ID is configured with trs-info, and the other associated resource set is configured with repetition.

[0733] 1. The RS used for service beam or current beam measurement can be the QCL source SSB of the CSI-RS ID, so the beam report includes the SSB ID and L1-RSRP.

[0734] a) Or explicit signaling, RRC / MAC CE / DCI indicates that the RS corresponding to the service beam is SSB.

[0735] 2. Since the RS used for serving beam or current beam measurements can be either a CSI-RS ID or the SSB of the QCL source of that CSI-RS ID, the beam report here does not need to directly indicate the SSB ID. Only a 1-bit indicator field is needed to indicate whether the RS type is CSI-RS (with repetition configured) or SSB.

[0736] d) Beam reports include two L1-RSRPs.

[0737] i. For example, case 1 and case 3 mentioned above; or only case 3.

[0738] 1. The beam report includes the L1-RSRP corresponding to CSI-RS and SSB respectively.

[0739] a) Or explicit signaling, RRC / MAC CE / DCI indicates that the RS corresponding to the service beam is CSI-RS and SSB.

[0740] 2. The default rule stipulates that the first L1-RSRP corresponds to CSI-RS and the second L1-RSRP corresponds to SSB.

[0741] e) The beam report includes two L1-RSRPs and the RS-related information corresponding to the L1-RSRPs.

[0742] i. For example, case 1 and case 3 above; or only case 3.

[0743] 1. The beam report includes the L1-RSRP corresponding to CSI-RS and SSB respectively.

[0744] a) Or explicit signaling, RRC / MAC CE / DCI indicates that the RS corresponding to the service beam is CSI-RS and SSB.

[0745] 2. RS-related information can be at least one of the following:
