Patent ID: 11582804

Abstract:
Systems and methods related to UL communications in a wireless network are provided. A UE receives an indication of a plurality of TXOPs for a RACH procedure from a BS. In an embodiment, the UE starts a timer after either successfully transmitting a random access message to the BS or failing to succeed in any of the TXOPs. In another embodiment, the UE starts the timer at a pre-agreed time after one of the TXOPs, regardless of whether the random access message has been successfully transmitted yet or not. In another embodiment, the UE receives as part of a RACH response an indication of whether the RACH response is split into multiple parts. If the UE does not locate an identifier corresponding to the UE in the RACH response, the UE checks for the indication and, if present, listen for the next RACH response identified from the indication.
