Methods, systems, and devices for wireless communications are described. A first wireless device, such as a user equipment (UE), may be configured to communicate with one or more other wireless devices (e.g., another UE) via sidelink communications. The first wireless device may receive an indication of a schedule of resources for sidelink communications to be performed over a communication beam, the schedule indicating a set of resources corresponding to a beam configuration for the sidelink communications with a second wireless device. The first wireless device may communicate with the second wireless device via one or more sidelink channels based on configuring the communication beam using the beam configuration over the set of resources. In some examples, the indication of the schedule of resources may be received in a confirmation of the schedule established by the second wireless device or, in some examples, in a request to establish the schedule.
