Abstract
Methods, systems, and devices for wireless communication are described. A base station may transmit, using a first base station beam, a first message to a user equipment (UE). The first message may include a pre-grant communication and a plurality of downlink beam refinement reference signals (D-BRRSs). The base station may receive a second message from the UE in response to the first message. The second message may include a pre-grant acknowledgement and a plurality of uplink beam refinement reference signals (U-BRRSs). The base station may transmit, using a second base station beam, a third message to the UE. A width of the second base station beam may be less than a width of the first base station beam.
