(EN) A dynamic UE capability message specifying a number of beams to be evaluated within different groups of UE TX beam directions associated with different antenna arrays of UE may be communicated to a transmit receive point (TRP). Each group of UE TX beam directions may include beam directions that are candidates for uplink data transmission. Based on information in the dynamic UE capability message,the TRP can assign SRS resources (for uplink beam management or uplink channel sounding) and/or schedule a multi-layer MIMO uplink transmission in accordance with a UE capability constraint. This mayensure that the SRS resources assignment and/or scheduled multi-layer MIMO uplink transmission is consistent with the UE's beamforming capabilities.
(ZH) 一种可向收发点(transmit receive point,简称TRP)传送的动态UE能力消息,其中,所述动态UE能力消息指定在与UE的不同天线阵列相关联的不同UE TX波束方向组中待评估的波束数量。每个UE TX波束方向组可包括用于上行数据传输的候选波束方向。根据所述动态UE能力消息中的信息,所述TRP可以根据UE能力约束分配SRS资源(用于上行波束管理或上行信道探测)和/或调度多层MIMO上行传输。这可以确保所述SRS资源分配和/或调度的多层MIMO上行传输与所述UE的波束成形功能一致。
