1. A method for selecting beam pairs in a beamforming-based communication system, the method comprising:
receiving, by a user equipment (UE) from a base station (BS), a plurality of transmit (Tx) beams on a plurality of receive (Rx) beams;
determining, by the UE, beam parameters associated with a plurality of Tx and Rx beam pairs changing at a frequency above a first threshold;
deriving, by the UE, a beam selection metric for the plurality of Tx and Rx beam pairs using the beam parameters;
identifying, by the UE, a subset of Tx and Rx beam pairs among the plurality of Tx and Rx beam pairs with the beam selection metric above a second threshold; and
prioritizing scanning of the subset of Tx and Rx beam pairs to select a Tx and Rx beam pair for communication.
