Apparatus and methods for enhancing multi-beam operation in wireless networks

Abstract

A method of uplink beam selection that includes receiving, by a user equipment (UE), one or more messages comprising configuration parameters of reference signals associated with a plurality of downlink beams comprising a first downlink beam; first determining, based on a beam sweeping process comprising measurement, of the reference signals, a plurality of uplink beams associated with the first downlink beam; second determining a first subset of uplink beams, of the plurality of uplink beams, that satisfy maximum permissible exposure (MPE) limits and that are not subject to link failure; first transmitting, to a base station (BS), a configuration message including configuration parameters of the first subset of the uplink beams; and second transmitting, by the UE, uplink data or control information using one or more beams of the first subset of the uplink beams.
