ENHANCEMENTS FOR UPLINK BEAM OPERATIONS

Abstract:

An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for uplink (UL) beam selection in a New Radio (NR) network, the processing circuitry is to decode a medium access control (MAC) control element (CE) from a base station. The MAC CE identifies a sounding reference signal (SRS) resource set and a plurality of spatial relationship reference signals. An SRS is selected from the SRS resource set. A beam direction associated with a spatial relationship reference signal of the plurality of spatial relationship reference signals is derived. The spatial relationship reference signal corresponds to the selected SRS. The SRS is encoded for beamforming to transmit the selected SRS in the derived beam direction.
