Abstract: Methods, systems, and devices for wireless communications are described that provide for user equipment (UE) in sidelink communications to agree on transmission directions and a traffic pattern for a sidelink channel, where a transmitting UE has higher priority in channel access than a receiving UE. When establishing a connection via sidelink, two or more UEs may agree on a resource pattern for a set of sidelink resources where a first UE has higher priority than a second UE for a first subset of resources.
