Patent ID: 11147078

Abstract:
A method for a UE includes determining whether a contention-free random access resource associated with a first Synchronization Signal Block (SSB) is received, when received, determining whether a first Synchronization Signal-Reference Signal Received Power (SS-RSRP) of the first SSB is greater than a first threshold, when the first SS-RSRP of the first SSB is greater than the first threshold, selecting, by the processing circuitry, a beam associated with the contention-free random access resource associated with the first SSB for transmitting a random access preamble. If the first SS-RSRP of the first SSB is not greater than the first threshold, the method includes selecting a beam associated with a contention-based random access resource associated with a second SSB for transmitting the random access preamble, where a second SS-RSRP of the second SSB is greater than the first threshold.
