Claim of US Patent No. 10,485,027

1. A method of wireless communication at a user equipment (UE), comprising:identifying data to be transmitted to a base station;
initiating a timer based at least in part on identifying the data;
monitoring for one or more downlink transmissions from the base station, the one or more downlink transmissions indicating scheduled uplink resources allocated for uplink short transmissions (ULSTs);
performing a ULST associated with the identified data using the scheduled uplink resources upon detection of the one or more downlink transmissions from the base station before expiration of the timer; and
initiating, after expiration of the timer and in an absence of the one or more downlink transmissions being detected before expiration of the timer, a listen-before talk (LBT) procedure during a ULST window.
