Abstract: Wireless communication methods and devices for selective receiver-assisted channel sensing are provided. In some aspects, one or more receivers (e.g., UEs) can be selectively configured to perform receiver-assisted channel sensing (e.g., class A channel sensing) using at least one of trigger signaling and channel sensing configuration by a BS, UE capabilities, or operational mode. For example, a method for wireless communication performed by a user equipment (UE) includes: sensing a channel based on at least one of a receiver-assisted channel sensing trigger, or a UE capability; and transmitting, to a base station (BS) based on the sensing, channel sensing information.

Abstract: Mechanisms for directional channel occupancy monitoring for a frequency band among multiple networks are provided. In one aspect, a method of wireless communication includes monitoring, in a shared frequency band in a plurality of beam directions, for signals associated with one or more wireless networks different from the first wireless network. The monitoring includes: detecting, in the shared frequency band and in at least a first beam direction of the plurality of beam directions, a first signal associated with a second wireless network; and up-dating a channel occupancy list to indicate that at least a portion of the shared frequency band is occupied in at least the first beam direction. The method also includes transmitting, in the shared frequency band, a second signal in a second beam direction of the plurality of beam directions based on the channel occupancy list.
