5. A method for wireless communications by a user equipment (UE), comprising:
determining a quasi-co-location (QCL) relationship of an aperiodic sounding reference signal (SRS), wherein:
the determination of the QCL relationship is based on:
an offset parameter associated with a downlink control information (DCI) scheduling at least the aperiodic SRS, and
a threshold value of a time for the UE to switch between beams, and
determining the QCL relationship of the aperiodic SRS comprises determining to use a QCL relationship of a physical downlink control channel (PDCCH) of a control resource set (CORESET) having a lowest identifier (CORESET-ID) when the offset parameter is lower than the threshold value; and
transmitting the aperiodic SRS according to the determined QCL relationship.
