USER EQUIPMENT SIDE ENHANCED CLEAR CHANNEL ASSESSMENT LENGTH INDICATION

Abstract:

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a grant scheduling an acknowledgement feedback transmission for the grant. The UE may identify, based at least in part on a first timing associated with the grant, a second timing associated with the acknowledgment feedback transmission, or a combination thereof, a duration for a channel clearance procedure to be performed before transmitting the acknowledgement feedback transmission. The UE may perform the channel clearance procedure using the identified duration. The UE may transmit the acknowledgement feedback transmission based at least in part on a result of the channel clearance procedure.
