US 11,700,638 B2 · Collaborative sensing and sharing for sidelink communications

Abstract

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may belong to a group of UEs and may identify a channel sensing schedule for the group of UEs. The channel sensing schedule may include sensing windows and resource reservation windows corresponding to each UE of the group of UEs. The channel sensing schedule may establish a pattern for the sensing windows and resource reservation windows such that the UEs may take turns performing sensing and resource selection. During a sensing window associated with the UE, the UE may sense a set of resources of a sidelink communication link to identify candidate resources. The UE may transmit, to the other UEs of the group, a message indicating results of the sensing, such as an indication of resource reservations, candidate resources, or the like. The other UEs may identify and select candidate resources based on the message.
