Beam update techniques in beamformed wireless communications

Abstract:

Methods, systems, and devices for wireless communications are described in which a UE may transmit an indication to a base station that the UE supports a beam update procedure that updates one or more beamforming parameters of one or more transmission beams. The UE may establish a connection with the base station via the one or more transmission beams. The UE may receive a medium access control (MAC) control element (CE) communication to initiate the beam update procedure, the received MAC-CE communication indicating one or more aperiodic sounding reference signal (SRS) resources to be used in the beam update procedure. The UE may perform the beam update procedure, based on the MAC-CE communication, to update one or more beamforming parameters of the one or more transmission beams.
