Abstract
Apparatuses, systems, and methods for a wireless device to perform methods to implement mechanisms for performing a listen again after talk procedure to detect collisions over an access medium. The wireless device may determine a frequency and configuration of modified transmission frames for transmission over an access medium (licensed or unlicensed) and may further determine a timing of the modified transmission frames within a transmission occasion. The wireless device may detect, during a listening period of the modified transmission frame, a collision and may adjust, based, at least in part, on the detected collision, a remaining transmission schedule for the transmission schedule and/or LBT parameters.
