Abstract:
Certain aspects of the present disclosure provide techniques for beam refinement procedures including dynamic signaling and/or selection of beam-switching latency for beam refinement procedures using inter- and/or intra-antenna module beam switching. A method by a base station (BS) includes configuring a user equipment (UE) with one or more reference signal (RS) resource sets. Each of the one or more RS resource sets is associated with a first or second type of beam refinement procedure. The BS receives an indication from the UE of at least a first latency and a second latency, longer than the first latency. The BS dynamically selects, for each RS transmission using one of the configured resource sets, the first or second latency. The BS sends the RS transmissions at the selected latency with respect to downlink control information (DCI) triggering the RS transmissions for the first or second type of beam refinement procedure.
