Abstract

A user equipment (UE) is configured to vary a number of chains in uplink or downlink communications with a base station (BS). The UE includes a processor coupled to a transceiver. The processor is configured to: identify a full-chain beam for a downlink reception based on a beam sweeping; determine a number of activated chains for an uplink transmission; and determine a sub-chain uplink transmission beam.
