Abstract
Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for beam refinement via physical random access channel (PRACH) repetition. A method that may be performed by a network entity includes determining resources to monitor for a PRACH transmission sent from a user equipment (UE) as part of a random access channel (RACH) procedure, performing receive beam sweeping when receiving PRACH repetitions sent using the determined resources, using results of the receive beam sweeping to refine one or more beams and to select a refined beam of the refined one or more beams, and using the selected refined beam for at least one of receiving a subsequent message from the UE as part of the RACH procedure or sending a subsequent message to the UE as part of the RACH procedure.
