1. A method for wireless communication by a user equipment (UE), comprising:
obtaining information for performing a beam refinement procedure, wherein the information indicates which channel state information reference signals (CSI-RSs) of a set of CSI-RSs are to be transmitted by a base station using a same transmit beam;
deciding, based on the information, which receive beams of a plurality of receive beams to use for receiving the CSI-RSs transmitted by the base station, wherein the receive beams used by the UE for receiving the CSI-RSs are different from the transmit beam used by the base station to transmit the CSI-RSs; and
receiving the CSI-RSs in accordance with the decision.
