Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmission-adjusting wireless node may transmit a first communication via a sidelink channel. The transmission-adjusting wireless node may receive, from a feedback-reporting wireless node, transmission-specific information relating to at least one of a channel quality of the sidelink channel or a power level for the transmission-adjusting wireless node. The transmission-specific information may be based at least in part on the first communication. The transmission-adjusting wireless node may adjust, based at least in part on the transmission-specific information, a transmission property of the transmission-adjusting wireless node to obtain an adjusted transmission property. The transmission-adjusting wireless node may transmit a second communication via the sidelink channel using the adjusted transmission property. Numerous other aspects are provided.
