Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in connection with minimizing D2D overhead resource usage. In one example, a first UE is equipped to measure a first received power value from a second UE with which the first UE has a D2D link, and a received power value from each UE of one or more other UEs, determine whether the received power value from any of the one or more other UEs is greater than a relevant interferer threshold, and transmit the received power value for any of the one or more other UEs for which the received power value is determined to be greater than the relevant interferer threshold. In an aspect, the relevant interferer threshold may be based on a fractional value of the first received power value.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a resource assignment from a serving base station for a device-to-device (D2D) link with a transmitter, attempts to receive a data packet from the transmitter based on the resource assignment, sends an acknowledgment (ACK) only to the serving base station when reception of the data packet succeeds, and sends a negative acknowledgment (NACK) only to the transmitter when the reception of the data packet fails. In an aspect, the apparatus receives a resource assignment from a serving base station for a D2D link with a receiver, sends a data packet to the receiver based on the resource assignment, and assumes the data packet is successfully received at the receiver unless a NACK is received from the receiver, wherein the NACK indicates a failed reception of the data packet at the receiver.

Abstract: A method, a computer program product, and an apparatus are provided. The apparatus determines a degree of a link based on interference observed from at least one other link, determines a priority of the link based on the determined degree, and decides whether to yield based on the determined priority. The priority of the link may further be based on a determined data rate of the link. The apparatus may transmit the priority to another device via a request to send (RTS) signal and/or a clear to send (CTS) signal. The apparatus may also determine a priority associated with an active link and decide whether to yield to the active link by comparing the determined priority of the link with the priority of the active link.
