Abstract
Methods, systems, and devices for wireless communications are described. A device may be configured to support multi-beam, or multi-panel operations, or both which may allow multiple sidelink transmissions to occur simultaneously. In some cases, flexible beam-management for the beamformed sidelink communications is implemented to manage the beams. A transmitting UE may indicate transmission beam information to the base station that the base station may use to schedule sidelink transmissions as part of a beam management procedure. The beam management procedure may allow a transmitting UE to update transmission beam information based on the mobility of the sidelink UEs and other environmental factors. In some cases, beam management includes a beam training procedure that may be implemented to refine the sidelink beams, where support for multi-panel and multi-beam operation may allow for multiple beams to be trained simultaneously.
