Abstract
A user equipment (UE) includes a request receipt component, an interference component, and a grant/deny component. The request receipt component is configured to receive a first signal indicating a request to transmit to the UE from a first transmitting UE and to receive one or more additional signals indicating that one or more additional transmitting UEs are requesting to transmit to corresponding target UEs. The interference component identifies, based on a received power of the first signal and the one or more additional signals, one or more potentially incompatible UEs. The incompatible UEs may include at least one of the one or more additional transmitting UEs. The grant/deny component is configured to send a signal indicating a block on transmission by the one or more incompatible UEs.
