Abstract (en)

[origin: WO2022240981A1] A user equipment (UE) may transmit a first random access message to a base station in a first bandwidth part (BWP), switch from the first BWP to a second BWP, and start a timer following a time gap after transmission of the first random access message in the first BWP, the timer associated with a window of time for receiving a second random access message from the base station in the second BWP. The window of time may be a random access response (RAR) window or a contention resolution window that may extend until the expiration of the timer. The switch from the first BWP to the second BWP may be based on a subcarrier spacing (SCS) change from a first SCS to a second SCS.
