Methods, systems, and devices for wireless communications are described. Aspects of the present disclosure provide for a user equipment (UE) performing contention-based access to utilize historical pathloss measurements to identify available resources for beamformed sidelink communications. The historical pathloss measurements may be obtained by the UE, by one or more other UEs, or both, where the UE may combine its own historical pathloss measurements with historical pathloss measurements obtained at the one or more other UEs. Such historical pathloss measurements may allow the UE to determine if one or more beam combinations associated with the resources may cause unacceptable interference (e.g., interference satisfying a threshold) while reducing signaling overhead associated with exchanges of inter-UE coordination messages. Accordingly, the UE may determine to yield transmissions over one or more resources or to yield reception to allow other UEs to utilize the one or more resources.
