Abstract
Various aspects of this disclosure generally relate to wireless communications. [Solution] In some embodiments, a source user device (UE) may transmit a first sidelink communication to a target UE. The source UE may receive a transmit power control command for a second sidelink communication, at least in part, based on having transmitted the first sidelink communication to the target UE. The source UE may transmit the second sidelink communication using the transmit power determined at least in part based on the transmit power control command. Numerous other embodiments are provided.
