UE/gNB transmission detection and impact on reliability

Abstract:

A method of wireless communication includes receiving, by a user equipment (UE) from a base station, downlink transmissions, and performing, by the UE, a listen before talk (LBT) procedure in an LBT occasion provisioned, by the base station, for the UE immediately prior to an uplink transmission that includes an acknowledgement of a downlink transmission. The method also includes transmitting, by the UE to the base station, the uplink transmission based on results of the LBT procedure. In another aspect, a method of wireless communication includes provisioning, by a base station for all served UEs, are LBT occasion immediately prior to an uplink transmission by the UEs. The uplink transmission includes an acknowledgement of a downlink transmission. The method additionally includes transmitting, by the base station to the UEs, downlink transmissions, and receiving, by the base station, the uplink transmission.
