Title
(EN) SL RELIABILITY ENHANCEMENT BY HALF DUPLEX AND COLLISION DETECTION
Abstract
(EN)

In one aspect, a method of wireless communication includes receiving, by a first user equipment (UE), a first transmission from a second UE for a new radio (NR) sidelink channel. The method also includes receiving, by the first UE, a second transmission from a third UE for the sidelink channel. The method further includes transmitting, by the first UE, a feedback transmission based on a medium contention event for the first and second transmissions of the NR sidelink channel and on a range condition. In additional aspects, the feedback transmission is transmitted based on a quality condition, or both a range condition and a quality condition. Other aspects and features are also claimed and described.
