Handling gaps in uplink transmission in new radio unlicensed

Abstract:

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a set of one or more uplink grants scheduling at least a first uplink transmission and a second uplink transmission during a channel occupancy time of an unlicensed radio frequency spectrum band. The UE may identify a transmission gap between the first uplink transmission and the second uplink transmission of the plurality of uplink transmissions by the UE during the channel occupancy time, the transmission gap exceeding a threshold time. The UE may determine that the transmission gap corresponds to a lost uplink grant. The UE may modify the first uplink transmission or the second uplink transmission based at least in part on the determination that the transmission gap corresponds to the lost uplink grant.
