Beam Configuration Of A Smart MMW Repeater For Forwarding RACH Message 1

Abstract:

Various aspects include methods for receiver (RX) beam sweep configuration of a millimeter wave (MMW) repeater during random access channel (RACH) procedures. Various embodiments may include determining two or more different RX beam sweep configurations for one or more RACH occurrences (ROs) associated with a synchronization signal block (SSB), generating a RACH configuration message indicating the two or more different RX beam sweep configurations for the one or more ROs, and sending the RACH configuration message to an MMW repeater. Various embodiments may also include receiving a RACH configuration message indicating two or more different RX beam sweep configurations for one or more ROs associated with an SSB, and controlling one or more RX antennas of the MMW repeater to perform RX beam sweeping during the one or more ROs according to the RACH configuration message to receive a RACH message 1 from a computing device.
