Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitting (Tx) user equipment (UE) may receive, from a plurality of receiving (Rx) UEs, indications of channel busy ratios (CBRs) associated with the plurality of Rx UEs, respectively. The Tx UE may combine the CBRs to obtain a combined CBR associated with the Tx UE. The Tx UE may adjust a resource utilization based at least in part on the combined CBR associated with the Tx UE. Numerous other aspects are described.
