Methods, systems, and devices for wireless communications are described to reduce interference caused by power leakage. A first user equipment (UE) or a base station may select communication resources for a sidelink communication based on a distance between UEs reserving frequency resources in a same time window. The first UE or the base station may determine a distance parameter between the first UE and one or more other UEs (e.g., including a second UE) reserving frequency resources within the time window. The distance parameter may represent a physical distance between the first and second UEs or a reference signal received power of the second UE as received by the first UE. The first UE or the base station may select communication resources based on whether the distance parameter is below a threshold, and the first UE may communicate the sidelink communication using the selected resources.
