第一方面的实施例Embodiments of the first aspect

本申请实施例提供一种波束管理方法，从终端设备侧进行说明。An embodiment of the present application provides a beam management method, which is described from the terminal device side.

图2是本申请实施例的波束管理方法的一个示意图，如图2所示，该方法包括：FIG. 2 is a schematic diagram of a beam management method according to an embodiment of the present application. As shown in FIG. 2 , the method includes:

201，终端设备接收来自网络设备的配置信息；所述配置信息用于配置波束管理和/或波束上报；201. A terminal device receives configuration information from a network device; the configuration information is used to configure beam management and/or beam reporting;

202，所述终端设备向所述网络设备发起波束上报。202. The terminal device initiates beam reporting to the network device.

值得注意的是，以上附图2仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图2的记载。It is worth noting that FIG. 2 above only schematically illustrates the embodiment of the present application, but the present application is not limited to For example, the execution order of each operation can be appropriately adjusted, and other operations can be added or some operations can be reduced. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description of Figure 2 above.

在一些实施例中，终端设备在条件满足和/或事件触发的情况下，通过MAC CE和/或调度请求(SR)向所述网络设备上报一个或多个波束的信息。In some embodiments, when conditions are met and/or events are triggered, the terminal device reports information of one or more beams to the network device through MAC CE and/or scheduling request (SR).

例如，对于UE发起(initiate)的波束管理，UE可以在某些条件下或者如果某些事件被触发的情况下，自主地向gNB报告一个或多个波束的信息。例如，可以通过已有的MAC CE发送报告，也可以通过新定义的MAC CE发送报告。此外，除了MAC CE之外，UE可以配置有专用SR资源，或者也可以使用现有的SR资源；本申请不限于此，还可以是其他资源。For example, for UE-initiated beam management, the UE may autonomously report information of one or more beams to the gNB under certain conditions or if certain events are triggered. For example, the report may be sent through an existing MAC CE or a newly defined MAC CE. In addition, in addition to the MAC CE, the UE may be configured with a dedicated SR resource or may use an existing SR resource; the present application is not limited thereto and may also be other resources.

在一些实施例中，所述MAC CE包括如下至少之一：信道状态信息参考信号资源指示(CRI，CSI-RS resource indicator)、同步信号块资源指示(SSBRI，SSB resource indicator)、L1-RSRP、L1-SINR、物理层标识、成员载波标识、小区标识、部分带宽(BWP)标识。本申请不限于此，例如可以包括以上的一种信息，也可以包括两种或以上的任意组合，还可以包括其他信息。In some embodiments, the MAC CE includes at least one of the following: channel state information reference signal resource indicator (CRI, CSI-RS resource indicator), synchronization signal block resource indicator (SSBRI, SSB resource indicator), L1-RSRP, L1-SINR, physical layer identifier, component carrier identifier, cell identifier, and partial bandwidth (BWP) identifier. The present application is not limited to this, for example, it may include one of the above information, or any combination of two or more, and may also include other information.

例如，如果报告了多个CRI/SSBRI，MAC CE中可以包括每个CRI/SSBRI的L1-RSRP/L1-SINR。再例如，如果报告了多个CRI/SSBRI，MAC CE中可以包括CRI/SSBRI的L1-RSRP/L1-SINR的差值；例如MAC CE中可以包括一个参考L1-RSRP/L1-SINR以及多个基于该参考L1-RSRP/L1-SINR的差值。For example, if multiple CRI/SSBRI are reported, the MAC CE may include the L1-RSRP/L1-SINR of each CRI/SSBRI. For another example, if multiple CRI/SSBRI are reported, the MAC CE may include the difference of the L1-RSRP/L1-SINR of the CRI/SSBRI; for example, the MAC CE may include a reference L1-RSRP/L1-SINR and multiple differences based on the reference L1-RSRP/L1-SINR.

图3是本申请实施例的波束管理方法的另一示意图。如图3所示，该方法包括：FIG3 is another schematic diagram of a beam management method according to an embodiment of the present application. As shown in FIG3 , the method includes:

301，终端设备接收来自网络设备的配置信息；301, the terminal device receives configuration information from the network device;

例如，配置信息用于配置波束管理和/或波束上报，例如可以包括用于波束管理的参考信号配置，也可以包括用于波束上报的资源配置。For example, the configuration information is used to configure beam management and/or beam reporting, and may include reference signal configuration for beam management, and may also include resource configuration for beam reporting.

302，终端设备进行波束管理；302, the terminal device performs beam management;

例如，终端设备可以根据配置信息，接收网络设备发送的CSI-RS进行波束测量。例如可以进行beam sweeping以选出一个或多个候选波束。关于进行基于AI/ML的波束管理，也可以使用非AI/ML的波束管理；具体内容可以参考相关技术。For example, the terminal device can receive the CSI-RS sent by the network device according to the configuration information to perform beam measurement. For example, beam sweeping can be performed to select one or more candidate beams. Regarding AI/ML-based beam management, non-AI/ML beam management can also be used; for specific content, please refer to the relevant technology.

303，终端设备向网络设备发起波束上报。303. The terminal device initiates a beam report to the network device.

例如，终端设备在某个事件被触发或者某个条件被满足的情况下，自主地发起波束上报。该波束上报可以仅包括当前波束的信息(例如是否质量变差)，也可以包括一个或多个候选波束的信息。For example, when an event is triggered or a condition is met, the terminal device autonomously initiates a beam report. The beam report may include only the information of the current beam (such as whether the quality has deteriorated), or may include a or information of multiple candidate beams.

值得注意的是，以上附图3仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图3的记载。It is worth noting that the above FIG. 3 is only a schematic illustration of the embodiment of the present application, but the present application is not limited thereto. For example, the execution order between the various operations can be appropriately adjusted, and other operations can be added or some operations can be reduced. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description of the above FIG. 3.

以下再对终端设备发起波束上报(例如事件触发)进行示意性说明。The following is a schematic illustration of the terminal device initiating beam reporting (eg, event triggering).

在一些实施例中，不同于当前波束的第一波束的质量超过第一阈值(ΔTH1)且持续第一周期(ΔT1)，则所述波束上报被触发；其中，所述第一周期和/或所述第一阈值被预定义或被配置。In some embodiments, the beam reporting is triggered when the quality of a first beam different from the current beam exceeds a first threshold (ΔTH1) and lasts for a first period (ΔT1); wherein the first period and/or the first threshold are predefined or configured.

图4是本申请实施例的事件触发波束上报的另一示例图。如图4所示，如果UE发现另一个波束(图4所示的候选波束)的质量超过阈值ΔTH1且持续ΔT1，则波束上报被触发。其中阈值(ΔTH1)和/或周期(ΔT1)可以是预定义或可配置的。或者，定时器(T1)可以被预定义或周期性配置，并且如果定时器到期，则波束上报被触发。可以基于L1-RSRP/L1-SINR或假设的BLER(hypothetical BLRE)来评估波束的质量。Figure 4 is another example diagram of event-triggered beam reporting in an embodiment of the present application. As shown in Figure 4, if the UE finds that the quality of another beam (the candidate beam shown in Figure 4) exceeds the threshold ΔTH1 and lasts for ΔT1, the beam reporting is triggered. The threshold (ΔTH1) and/or the period (ΔT1) may be predefined or configurable. Alternatively, the timer (T1) may be predefined or periodically configured, and if the timer expires, the beam reporting is triggered. The quality of the beam may be evaluated based on L1-RSRP/L1-SINR or hypothetical BLER (hypothetical BLRE).

在一些实施例中，不同于当前波束的第一波束的质量超过所述当前波束的质量的量达到第二阈值(ΔTH2)且持续第二周期(ΔT2)，则所述波束上报被触发；其中，所述第二周期和/或所述第二阈值被预定义或被配置。In some embodiments, the beam reporting is triggered when the quality of a first beam different from the current beam exceeds the quality of the current beam by an amount that reaches a second threshold (ΔTH2) and lasts for a second period (ΔT2); wherein the second period and/or the second threshold are predefined or configured.

图5是本申请实施例的事件触发波束上报的另一示例图。如图5所示，如果UE发现另一个波束(图5所示的候选波束)的质量超过当前波束的质量(超过量大于阈值ΔTH2)且持续ΔT2，则波束上报被触发。其中阈值(ΔTH2)和/或周期(ΔT2)可以是预定义或可配置的。或者，定时器(T2)可以被预定义或周期性配置，并且如果定时器到期，则波束上报被触发。可以基于L1-RSRP/L1-SINR或假设的BLER(hypothetical BLRE)来评估波束的质量。Figure 5 is another example diagram of event-triggered beam reporting in an embodiment of the present application. As shown in Figure 5, if the UE finds that the quality of another beam (the candidate beam shown in Figure 5) exceeds the quality of the current beam (the excess is greater than the threshold ΔTH2) and lasts for ΔT2, the beam reporting is triggered. The threshold (ΔTH2) and/or the period (ΔT2) may be predefined or configurable. Alternatively, the timer (T2) may be predefined or periodically configured, and if the timer expires, the beam reporting is triggered. The quality of the beam may be evaluated based on L1-RSRP/L1-SINR or hypothetical BLER (hypothetical BLRE).

在一些实施例中，例如，在波束上报的MAC-CE中，如果仅报告一个CRI/SSBRI，则所报告的CRI/SSBRI是UE偏好(preferred)的，例如，具有最高L1-RSRP/L1-SINR的CRI/SSBRI，该L1-RSRP/L1-SINR的报告可以省略(是可选的)。如果报告了多个CRI/SSBRI，则第一个CRI/SSBRI可以是UE偏好(preferred)的，例如，具有最高L1-RSRP/L1-SINR的CRI/SSBRI。In some embodiments, for example, in the MAC-CE reported by the beam, if only one CRI/SSBRI is reported, the reported CRI/SSBRI is the UE preferred, for example, the CRI/SSBRI with the highest L1-RSRP/L1-SINR, and the report of the L1-RSRP/L1-SINR can be omitted (optional). If multiple CRI/SSBRIs are reported, the first CRI/SSBRI can be the UE preferred, for example, the CRI/SSBRI with the highest L1-RSRP/L1-SINR.

再例如，gNB可以为UE配置周期性/半持续性(periodic/semi-persistent)参考信号(CSI-RS、SSB)以进行监测/测量(或者所有的SSB可以用于测量)。在一个示例中，针对周期性/半持续性参考信号不配置L1-RSRP/L1-SINR上报。在另一示例中，用于波束失败检测(beam failure detection)和波束失败恢复中的新候选波束识别的参考信号可以被UE用于监测波束质量。For another example, the gNB can configure periodic/semi-persistent reference signals (CSI-RS, SSB) for the UE to monitor/measure (or all SSBs can be used for measurement). L1-RSRP/L1-SINR reporting is not configured for periodic/semi-persistent reference signals. In another example, the reference signals used for beam failure detection and new candidate beam identification in beam failure recovery can be used by the UE to monitor beam quality.

又例如，平均(averaged)或过滤(filtered)的层1测量(L1-RSRP/L1-SINR/hypothetical BLER)可用于触发事件。例如，候选波束在特定周期上的平均L1-RSRP超过当前波束特定阈值，则可以触发该事件。For another example, averaged or filtered layer 1 measurements (L1-RSRP/L1-SINR/hypothetical BLER) can be used to trigger an event. For example, the average L1-RSRP of a candidate beam over a specific period exceeds a specific threshold for the current beam, which can trigger the event.

又例如，考虑到载波聚合操作，如果在至少一个CC上，UE发现另一个波束的质量超过特定阈值(ΔTH1)且持续特定周期(ΔT1)，则触发波束上报。或者，考虑到载波聚合操作，如果在至少一个CC上，UE发现另一个波束的质量超过当前波束特定阈值(ΔTH2)且持续特定周期(ΔT2)，则触发波束上报。For another example, considering the carrier aggregation operation, if on at least one CC, the UE finds that the quality of another beam exceeds a specific threshold (ΔTH1) and lasts for a specific period (ΔT1), the beam reporting is triggered. Alternatively, considering the carrier aggregation operation, if on at least one CC, the UE finds that the quality of another beam exceeds the current beam specific threshold (ΔTH2) and lasts for a specific period (ΔT2), the beam reporting is triggered.

在一些实施例中，当前波束的质量低于第三阈值(ΔTH3)且持续第三周期(ΔT3)，则所述波束上报被触发；其中，所述第三周期和/或第三阈值被预定义或被配置。In some embodiments, the beam reporting is triggered when the quality of the current beam is lower than a third threshold (ΔTH3) and lasts for a third period (ΔT3); wherein the third period and/or the third threshold are predefined or configured.

图6是本申请实施例的事件触发波束上报的另一示例图。如图6所示，如果UE发现当前波束的质量低于阈值ΔTH3且持续ΔT3，则波束上报被触发。其中阈值(ΔTH3)和/或周期(ΔT3)可以是预定义或可配置的。或者，定时器(T3)可以被预定义或周期性配置，并且如果定时器到期，则波束上报被触发。可以基于L1-RSRP/L1-SINR或假设的BLER(hypothetical BLRE)来评估波束的质量。Figure 6 is another example diagram of event-triggered beam reporting of an embodiment of the present application. As shown in Figure 6, if the UE finds that the quality of the current beam is lower than the threshold ΔTH3 and lasts for ΔT3, the beam reporting is triggered. The threshold (ΔTH3) and/or the period (ΔT3) may be predefined or configurable. Alternatively, the timer (T3) may be predefined or periodically configured, and if the timer expires, the beam reporting is triggered. The quality of the beam may be evaluated based on L1-RSRP/L1-SINR or hypothetical BLER (hypothetical BLRE).

在一些实施例中，例如，在波束上报的MAC CE中，当前波束(或当前TCI state)的L1-RSRP/L1-SINR被上报。该当前波束(或当前TCI state)可以包括在该MAC CE中，或者，该当前波束(或当前TCI state)也可以不包括在该MAC CE中。UE可以保持测量当前波束(当前TCI state)。例如，UE可以保持监测PDCCH/CORESET。In some embodiments, for example, in the MAC CE reported by the beam, the L1-RSRP/L1-SINR of the current beam (or the current TCI state) is reported. The current beam (or the current TCI state) may be included in the MAC CE, or the current beam (or the current TCI state) may not be included in the MAC CE. The UE may keep measuring the current beam (current TCI state). For example, the UE may keep monitoring the PDCCH/CORESET.

再例如，平均(averaged)或过滤(filtered)的层1测量(L1-RSRP/L1-SINR/hypothetical BLER)可用于触发事件。例如，当前波束在特定周期上的平均L1-RSRP低于特定阈值，则可以触发该事件。As another example, averaged or filtered layer 1 measurements (L1-RSRP/L1-SINR/hypothetical BLER) can be used to trigger an event. For example, the average L1-RSRP of the current beam over a specific period is below a certain threshold, which can trigger the event.

又例如，考虑到载波聚合操作，如果在至少一个CC上，UE发现当前波束(或当前TCI state)的质量低于特定阈值(ΔTH3)且持续特定周期(ΔT3)，则触发波束上报。For another example, considering the carrier aggregation operation, if on at least one CC, the UE finds that the quality of the current beam (or current TCI state) is lower than a specific threshold (ΔTH3) and lasts for a specific period (ΔT3), the beam reporting is triggered.

在一些实施例中，不同于当前波束的第一波束的质量超过第一阈值(ΔTH1)且持续第一周期(ΔT1)，并且当前波束的质量低于第三阈值(ΔTH3)且持续第三周期(ΔT3)，则所述波束上报被触发；其中，所述第一周期和/或所述第一阈值和/或所述第三周期和/或第三阈值被预定义或被配置。 In some embodiments, the beam reporting is triggered when the quality of a first beam different from the current beam exceeds a first threshold (ΔTH1) and lasts for a first period (ΔT1), and the quality of the current beam is lower than a third threshold (ΔTH3) and lasts for a third period (ΔT3); wherein the first period and/or the first threshold and/or the third period and/or the third threshold are predefined or configured.

图7是本申请实施例的事件触发波束上报的另一示例图。如图7所示，如果UE发现当前波束的质量低于阈值ΔTH3且持续ΔT3，并且另一个波束(图7所示的候选波束)的质量超过阈值ΔTH1且持续ΔT1，则波束上报被触发。其中阈值(ΔTH1)和/或周期(ΔT1)和/或阈值(ΔTH3)和/或周期(ΔT3)可以是预定义或可配置的。或者，定时器(T4)可以被预定义或周期性配置，并且如果定时器到期，则波束上报被触发。可以基于L1-RSRP/L1-SINR或假设的BLER(hypothetical BLRE)来评估波束的质量。Figure 7 is another example diagram of event-triggered beam reporting in an embodiment of the present application. As shown in Figure 7, if the UE finds that the quality of the current beam is lower than the threshold ΔTH3 and lasts for ΔT3, and the quality of another beam (the candidate beam shown in Figure 7) exceeds the threshold ΔTH1 and lasts for ΔT1, the beam reporting is triggered. The threshold (ΔTH1) and/or the period (ΔT1) and/or the threshold (ΔTH3) and/or the period (ΔT3) may be predefined or configurable. Alternatively, the timer (T4) may be predefined or periodically configured, and if the timer expires, the beam reporting is triggered. The quality of the beam may be evaluated based on L1-RSRP/L1-SINR or hypothetical BLER (hypothetical BLRE).

此外，在MAC CE中，UE还可以向gNB报告UE偏好的一个或多个波束，即候选波束。例如，如果一个或多个波束的质量超过某个阈值ΔTH4达某个周期(ΔT4)，则可以将该波束报告为候选波束，其中阈值(ΔTH4)和周期(ΔT4)可以是预定义的或可配置的。或者，定时器(T4)可以被预定义或周期性配置。ΔTH4、ΔT4、T4可以分别与ΔTH1、ΔT1、T1相同。In addition, in MAC CE, the UE may also report one or more beams preferred by the UE, i.e., candidate beams, to the gNB. For example, if the quality of one or more beams exceeds a certain threshold ΔTH4 for a certain period (ΔT4), the beam may be reported as a candidate beam, where the threshold (ΔTH4) and the period (ΔT4) may be predefined or configurable. Alternatively, the timer (T4) may be predefined or periodically configured. ΔTH4, ΔT4, T4 may be the same as ΔTH1, ΔT1, T1, respectively.

在一些实施例中，不同于当前波束的第一波束的质量超过所述当前波束的质量的量达到第二阈值(ΔTH2)且持续第二周期(ΔT2)，并且当前波束的质量低于第三阈值(ΔTH3)且持续第三周期(ΔT3)，则所述波束上报被触发；其中，所述第二周期和/或所述第二阈值和/或所述第三周期和/或第三阈值被预定义或被配置。In some embodiments, the beam reporting is triggered when the quality of a first beam different from the current beam exceeds the quality of the current beam by an amount reaching a second threshold (ΔTH2) and lasts for a second period (ΔT2), and the quality of the current beam is lower than a third threshold (ΔTH3) and lasts for a third period (ΔT3); wherein the second period and/or the second threshold and/or the third period and/or the third threshold are predefined or configured.

图8是本申请实施例的事件触发波束上报的另一示例图。如图8所示，如果UE发现当前波束的质量低于阈值ΔTH3且持续ΔT3，并且另一个波束(图8所示的候选波束)的质量超过当前波束的质量(超过量大于阈值ΔTH2)且持续ΔT2，则波束上报被触发。其中阈值(ΔTH2)和/或周期(ΔT2)和/或阈值(ΔTH3)和/或周期(ΔT3)可以是预定义或可配置的。或者，定时器(T5)可以被预定义或周期性配置，并且如果定时器到期，则波束上报被触发。可以基于L1-RSRP/L1-SINR或假设的BLER(hypothetical BLRE)来评估波束的质量。Figure 8 is another example diagram of event-triggered beam reporting of an embodiment of the present application. As shown in Figure 8, if the UE finds that the quality of the current beam is lower than the threshold ΔTH3 and lasts for ΔT3, and the quality of another beam (the candidate beam shown in Figure 8) exceeds the quality of the current beam (the excess is greater than the threshold ΔTH2) and lasts for ΔT2, the beam reporting is triggered. The threshold (ΔTH2) and/or the period (ΔT2) and/or the threshold (ΔTH3) and/or the period (ΔT3) can be predefined or configurable. Alternatively, the timer (T5) can be predefined or periodically configured, and if the timer expires, the beam reporting is triggered. The quality of the beam can be evaluated based on L1-RSRP/L1-SINR or hypothetical BLER (hypothetical BLRE).

此外，在MAC CE中，UE还可以向gNB报告UE偏好的一个或多个波束，即候选波束。例如，如果一个或多个波束的质量超过当前波束某个阈值(ΔTH5)达某个周期(ΔT5)，则可以将该波束报告为候选波束，其中阈值(ΔTH5)和周期(ΔT5)可以是预定义的或可配置的。或者，定时器(T5)可以被预定义或周期性配置。ΔTH5、ΔT5、T5可以分别与ΔTH2、ΔT2、T2相同。In addition, in MAC CE, the UE may also report one or more beams preferred by the UE, i.e., candidate beams, to the gNB. For example, if the quality of one or more beams exceeds a certain threshold (ΔTH5) of the current beam for a certain period (ΔT5), the beam may be reported as a candidate beam, where the threshold (ΔTH5) and the period (ΔT5) may be predefined or configurable. Alternatively, the timer (T5) may be predefined or periodically configured. ΔTH5, ΔT5, T5 may be the same as ΔTH2, ΔT2, T2, respectively.

在一些实施例中，例如，在波束上报的MAC-CE中，如果仅报告一个CRI/SSBRI，则所报告的CRI/SSBRI是UE偏好(preferred)的，例如，具有最高L1-RSRP/L1-SINR的CRI/SSBRI，该L1-RSRP/L1-SINR的报告可以省略(是可选的)。如果报告了多个 CRI/SSBRI，则第一个CRI/SSBRI可以是UE偏好(preferred)的，例如，具有最高L1-RSRP/L1-SINR的CRI/SSBRI。In some embodiments, for example, in the MAC-CE reported by the beam, if only one CRI/SSBRI is reported, the reported CRI/SSBRI is the UE preferred, for example, the CRI/SSBRI with the highest L1-RSRP/L1-SINR, and the reporting of the L1-RSRP/L1-SINR can be omitted (is optional). CRI/SSBRI, the first CRI/SSBRI may be the one preferred by the UE, for example, the CRI/SSBRI with the highest L1-RSRP/L1-SINR.

再例如，在MAC CE中，可以包括当前波束(当前TCI状态)的质量，或者，也可以不包括当前波束(当前TCI状态)的质量。MAC CE的触发可以隐含地携带当前波束的质量不好的信息。For another example, in MAC CE, the quality of the current beam (current TCI state) may be included, or the quality of the current beam (current TCI state) may not be included. The triggering of MAC CE may implicitly carry information that the quality of the current beam is not good.

再例如，UE可以保持测量当前波束(当前TCI state)。例如，UE可以保持监测PDCCH/CORESET。gNB可以为UE配置周期性/半持续性(periodic/semi-persistent)参考信号(CSI-RS、SSB)以进行监测/测量(或者所有的SSB可以用于测量)。在一个示例中，针对周期性/半持续性参考信号不配置L1-RSRP/L1-SINR上报。在另一示例中，用于波束失败检测(beam failure detection)和波束失败恢复中的新候选波束识别的参考信号可以被UE用于监测波束质量。For another example, the UE may keep measuring the current beam (current TCI state). For example, the UE may keep monitoring PDCCH/CORESET. The gNB may configure periodic/semi-persistent reference signals (CSI-RS, SSB) for the UE to monitor/measure (or all SSBs may be used for measurement). In one example, L1-RSRP/L1-SINR reporting is not configured for periodic/semi-persistent reference signals. In another example, reference signals used for beam failure detection and identification of new candidate beams in beam failure recovery may be used by the UE to monitor beam quality.

又例如，平均(averaged)或过滤(filtered)的层1测量(L1-RSRP/L1-SINR/hypothetical BLER)可用于触发事件。例如，当前波束在特定周期上的平均L1-RSRP低于特定阈值，则可以触发该事件。For another example, averaged or filtered layer 1 measurements (L1-RSRP/L1-SINR/hypothetical BLER) can be used to trigger an event. For example, the average L1-RSRP of the current beam over a specific period is below a specific threshold, which can trigger the event.

又例如，考虑到载波聚合操作，如果在至少一个CC上，UE发现当前波束(或当前TCI state)的质量低于特定阈值(ΔTH3)且持续特定周期(ΔT3)，且候选波束的质量超过当前波束的质量(超过量大于阈值ΔTH2)且持续ΔT2，则触发波束上报。For another example, considering the carrier aggregation operation, if on at least one CC, the UE finds that the quality of the current beam (or current TCI state) is lower than a specific threshold (ΔTH3) and lasts for a specific period (ΔT3), and the quality of the candidate beam exceeds the quality of the current beam (the excess is greater than the threshold ΔTH2) and lasts for ΔT2, then the beam reporting is triggered.

以上示意性说明了波束上报的触发，以下再对本申请进一步说明。The above schematically illustrates the triggering of beam reporting, and the present application is further explained below.

在一些实施例中，针对终端设备发起的波束上报，用于波束上报的参数按照成员载波(CC)被配置；所述用于波束上报的参数包括如下至少之一：阈值、周期、定时器，本申请不限于此。In some embodiments, for beam reporting initiated by a terminal device, parameters for beam reporting are configured according to component carriers (CCs); the parameters for beam reporting include at least one of the following: a threshold, a period, and a timer, but the present application is not limited thereto.

在一些实施例中，针对终端设备发起的波束上报，用于波束上报的参数针对所有CC被配置；所述用于波束上报的参数包括如下至少之一：阈值、周期、定时器，本申请不限于此。In some embodiments, for beam reporting initiated by a terminal device, parameters for beam reporting are configured for all CCs; the parameters for beam reporting include at least one of the following: a threshold, a period, and a timer, but the present application is not limited thereto.

在一些实施例中，针对终端设备发起的波束上报，候选波束按照成员载波(CC)被上报，或者，候选波束针对所有CC被上报，或者，候选波束针对部分CC被上报，或者，候选波束针对所有CC的一个子集被上报。In some embodiments, for beam reporting initiated by a terminal device, candidate beams are reported according to component carriers (CCs), or candidate beams are reported for all CCs, or candidate beams are reported for some CCs, or candidate beams are reported for a subset of all CCs.

在一些实施例中，服务波束(或当前TCI状态)被改变，则针对终端设备发起的波束上报的定时器被重启(restarted)。In some embodiments, when the serving beam (or current TCI state) is changed, the timer for the beam report initiated by the terminal device is restarted.

在一些实施例中，多个事件被预定义；一个MAC CE对应一个事件，或者一个或多个事件在一个MAC CE中被指示。In some embodiments, multiple events are predefined; one MAC CE corresponds to one event, or one or more Multiple events are indicated in one MAC CE.

例如，可以定义多个事件(不同类型的事件)，例如，事件类型1、事件类型2等。可以引入多个MAC-CE，例如，每个事件对应一个MAC CE。或者，可以使用相同的一个MAC CE，并且可以在该MAC CE中指示事件类型。For example, multiple events (events of different types) may be defined, such as event type 1, event type 2, etc. Multiple MAC-CEs may be introduced, such as one MAC CE for each event. Alternatively, the same MAC CE may be used, and the event type may be indicated in the MAC CE.

再例如，可以定义多个MAC CE。例如，一个MAC CE用于一个CC，另一个MAC C用于多个CC。For another example, multiple MAC CEs may be defined, for example, one MAC CE is used for one CC, and another MAC CE is used for multiple CCs.

在一些实施例中，针对终端设备发起的波束上报，上报的MAC CE中包括当前波束(或当前TCI状态)质量变差的信息，则TCI切换(TCI switching)被所述网络设备通过DCI触发，或者，波束测量和/或TCI状态更新被所述网络设备通过RRC和/或MAC CE触发。In some embodiments, for the beam report initiated by the terminal device, the reported MAC CE includes information that the quality of the current beam (or current TCI state) has deteriorated, then TCI switching (TCI switching) is triggered by the network device through DCI, or beam measurement and/or TCI state update is triggered by the network device through RRC and/or MAC CE.

例如，对于UE发起的波束管理过程，如果所报告的MAC CE仅包含当前服务波束(当前TCI状态)变差的信息，则gNB接收到该MAC CE之后，gNB可以触发TCI切换(例如通过DCI)。或者，gNB可以触发波束测量，然后进行TCI切换或TCI状态更新。For example, for the beam management process initiated by the UE, if the reported MAC CE only contains information that the current serving beam (current TCI state) has deteriorated, the gNB can trigger TCI switching (e.g., through DCI) after receiving the MAC CE. Alternatively, the gNB can trigger beam measurement and then perform TCI switching or TCI state update.

在一些实施例中，针对终端设备发起的波束上报，上报的MAC CE中包括候选波束信息并且候选波束不在激活的TCI状态中，则TCI状态更新被所述网络设备触发，或者，波束测量被所述网络设备触发。In some embodiments, for beam reporting initiated by a terminal device, the reported MAC CE includes candidate beam information and the candidate beam is not in an activated TCI state, then the TCI state update is triggered by the network device, or the beam measurement is triggered by the network device.

例如，对于UE发起的波束管理过程，如果所报告的MAC CE包含候选波束信息，并且候选波束不在激活的TCI状态内，则gNB接收到该MAC CE之后，gNB可以触发TCI状态更新。或者，gNB可以触发波束测量，然后进行TCI切换或TCI状态更新。For example, for the beam management process initiated by the UE, if the reported MAC CE contains candidate beam information and the candidate beam is not in the activated TCI state, the gNB can trigger a TCI state update after receiving the MAC CE. Alternatively, the gNB can trigger beam measurement and then perform TCI switching or TCI state update.

在一些实施例中，针对终端设备发起的波束上报，上报的MAC CE中包括候选波束信息并且候选波束在激活的TCI状态中，则TCI状态更新被所述网络设备触发，或者，波束测量和/或TCI状态更新被所述网络设备通过RRC和/或MAC CE触发。In some embodiments, for beam reporting initiated by a terminal device, the reported MAC CE includes candidate beam information and the candidate beam is in an activated TCI state, then the TCI status update is triggered by the network device, or the beam measurement and/or TCI status update is triggered by the network device through RRC and/or MAC CE.

例如，对于UE发起的波束管理过程，如果所报告的MAC CE包含候选波束信息，并且候选波束在激活的TCI状态内，则gNB接收到该MAC CE之后，gNB可以触发TCI状态更新。或者，gNB可以触发波束测量，然后进行TCI切换或TCI状态更新。For example, for the beam management process initiated by the UE, if the reported MAC CE contains candidate beam information and the candidate beam is in the activated TCI state, the gNB can trigger a TCI state update after receiving the MAC CE. Alternatively, the gNB can trigger beam measurement and then perform TCI switching or TCI state update.

在一些实施例中，针对终端设备发起的波束上报，上报的MAC CE中包括候选波束信息并且候选波束在激活的TCI状态中，则TCI切换(TCI switching)被所述网络设备通过DCI触发，或者，波束测量和/或TCI状态更新被所述网络设备通过RRC和/或MAC CE触发。 In some embodiments, for beam reporting initiated by a terminal device, the reported MAC CE includes candidate beam information and the candidate beam is in an activated TCI state, then TCI switching is triggered by the network device via DCI, or beam measurement and/or TCI status update is triggered by the network device via RRC and/or MAC CE.

例如，对于UE发起的波束管理过程，如果所报告的MAC CE包含候选波束信息，并且候选波束在激活的TCI状态内，则gNB接收到该MAC CE之后，gNB可以触发TCI切换(例如通过DCI)。或者，gNB可以触发波束测量，然后进行TCI切换或TCI状态更新。For example, for the beam management process initiated by the UE, if the reported MAC CE contains candidate beam information and the candidate beam is in the activated TCI state, after the gNB receives the MAC CE, the gNB can trigger TCI switching (e.g., through DCI). Alternatively, the gNB can trigger beam measurement and then perform TCI switching or TCI state update.

在一些实施例中，针对终端设备发起的波束上报，上报的MAC CE中包括候选波束信息并且候选波束在激活的TCI状态中，则TCI切换(TCI switching)被所述终端设备通过所述MAC CE触发，所述上报的MAC CE被用于波束切换或TCI状态切换。In some embodiments, for beam reporting initiated by a terminal device, the reported MAC CE includes candidate beam information and the candidate beam is in an activated TCI state, then TCI switching is triggered by the terminal device through the MAC CE, and the reported MAC CE is used for beam switching or TCI state switching.

例如，对于UE发起的波束管理过程，如果所报告的MAC CE包含候选波束信息，并且候选波束在激活的TCI状态内，则UE所报告的MAC CE可以用于波束切换或TCI状态切换。在MAC CE中指示的候选波束将用于通信。For example, for the beam management process initiated by the UE, if the reported MAC CE contains candidate beam information and the candidate beam is in the activated TCI state, the MAC CE reported by the UE can be used for beam switching or TCI state switching. The candidate beam indicated in the MAC CE will be used for communication.

再例如，gNB可以确认接收到用于波束报告的MAC CE。UE接收来自gNB用于指示接收到所述MAC CE的确认，并且在所述MAC CE中指示的所述候选波束被所述终端设备和所述网络设备使用。For another example, the gNB may confirm receipt of a MAC CE for beam reporting. The UE receives a confirmation from the gNB indicating receipt of the MAC CE, and the candidate beam indicated in the MAC CE is used by the terminal device and the network device.

在一个示例中，该确认(acknowledge)可以是正常的上行授权，该上行授权调度与承载该MAC CE的PUSCH相同的HARQ进程ID的新传输。In one example, the acknowledgement can be a normal uplink grant that schedules a new transmission with the same HARQ process ID as the PUSCH carrying the MAC CE.

图9是本申请实施例的被MAC CE指示的候选波束的应用时间的一示例图。如图9所示，当gNB接收到用于波束上报的MAC CE并且gNB在与承载该MAC CE的PUSCH相对应的时隙n中发送确认时，将MAC CE中指示的候选波束从时隙n+ΔT6之后的第1个时隙开始应用于通信，其中ΔT6可以是预定义的或可配置的，或者取决于UE能力。FIG9 is an example diagram of the application time of the candidate beam indicated by the MAC CE in an embodiment of the present application. As shown in FIG9, when the gNB receives the MAC CE for beam reporting and the gNB sends a confirmation in the time slot n corresponding to the PUSCH carrying the MAC CE, the candidate beam indicated in the MAC CE is applied to the communication starting from the first time slot after the time slot n+ΔT6, where ΔT6 can be predefined or configurable, or depends on the UE capability.

在一些实施例中，针对终端设备发起的波束上报，上报的MAC CE中包括候选波束信息，则在所述MAC CE中指示的所述候选波束被所述网络设备通过DCI指示为激活的TCI状态。In some embodiments, for the beam report initiated by the terminal device, the reported MAC CE includes candidate beam information, and the candidate beam indicated in the MAC CE is indicated by the network device through DCI as an activated TCI state.

例如，对于UE发起的波束管理过程，如果所报告的MAC CE包含候选波束信息(无论候选波束是否在当前激活的TCI状态内)，则MAC CE中包含的候选波束可以被视为新激活的TCI状态。gNB可以使用DCI来指示新激活的TCI状态。即，gNB不需要进一步发送信令来更新TCI状态列表并通过现有的MAC CE激活TCI状态。For example, for the beam management process initiated by the UE, if the reported MAC CE contains candidate beam information (regardless of whether the candidate beam is within the currently activated TCI state), the candidate beam contained in the MAC CE can be regarded as the newly activated TCI state. The gNB can use DCI to indicate the newly activated TCI state. That is, the gNB does not need to send further signaling to update the TCI state list and activate the TCI state through the existing MAC CE.

再例如，gNB确认接收到用于波束报告的MAC CE。在一个示例中，该确认可以是正常的上行授权，该上行授权调度与承载该MAC CE的PUSCH相同的HARQ进程ID的新传输。As another example, the gNB acknowledges receipt of a MAC CE for beam reporting. In one example, the acknowledgement may be a normal uplink grant that schedules a new transmission with the same HARQ process ID as the PUSCH carrying the MAC CE.

图10是本申请实施例的被MAC CE指示的候选波束的应用时间的一示例图。如图 10所示，当gNB接收到用于波束上报的MAC CE并且gNB在与承载该MAC CE的PUSCH相对应的时隙n中发送确认时，将MAC CE中指示的候选波束从时隙n+ΔT7之后的第1个时隙开始作为激活的TCI状态，其中ΔT7可以是预定义的或可配置的，或者取决于UE能力。FIG. 10 is an example diagram of the application time of the candidate beam indicated by the MAC CE in an embodiment of the present application. As shown in Figure 10, when the gNB receives a MAC CE for beam reporting and the gNB sends an acknowledgment in time slot n corresponding to the PUSCH carrying the MAC CE, the candidate beam indicated in the MAC CE is used as the activated TCI state starting from the 1st time slot after time slot n+ΔT7, where ΔT7 can be predefined or configurable, or depends on the UE capability.

在一些实施例中，对于UE发起的波束管理过程，包含在MAC CE中的候选波束的最大数量，可以与激活TCI状态的现有MAC CE中能够指示的数量相同；例如，候选波束的最高数量为8。或者，包含在MAC-CE中的候选波束的最大数量可以与现有MAC CE不同。In some embodiments, for the UE-initiated beam management process, the maximum number of candidate beams included in the MAC-CE may be the same as the number that can be indicated in the existing MAC-CE with the TCI state activated; for example, the maximum number of candidate beams is 8. Alternatively, the maximum number of candidate beams included in the MAC-CE may be different from the existing MAC-CE.

以上各个实施例仅对本申请实施例进行了示例性说明，但本申请不限于此，还可以在以上各个实施例的基础上进行适当的变型。例如，可以单独使用上述各个实施例，也可以将以上各个实施例中的一种或多种结合起来。The above embodiments are merely exemplary of the embodiments of the present application, but the present application is not limited thereto, and appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

由上述实施例可知，考虑到终端设备侧具有关于波束质量的更及时的信息，终端设备可以发起波束上报或波束管理过程，从而不仅可以保持或提升波束管理的准确性和可靠性，而且可以减少信令开销。It can be seen from the above embodiments that, considering that the terminal device side has more timely information about beam quality, the terminal device can initiate a beam reporting or beam management process, which can not only maintain or improve the accuracy and reliability of beam management, but also reduce signaling overhead.
