Patent ID: 10966164

Abstract:
A user equipment (UE) can include processing circuitry configured to, during a physical random access channel (PRACH) procedure, select a first synchronization signal (SS) block from a plurality of SS blocks within a received SS burst set, the SS block selected based on signal quality measurements of the plurality of SS blocks. A PRACH preamble is encoded for transmission to a base station using a PRACH resource subset corresponding to the selected SS block, the transmission using a UE transmit (Tx) beam of a plurality of available Tx beams and transmit power indicated by a power ramping counter. Upon failing to detect a random access response (RAR) from the base station, a second SS block is selected, the power ramping counter is reset, and the PRACH preamble is encoded for re-transmission using a second PRACH resource subset and transmit power indicated by the reset power ramping counter.
