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.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives downlink data from a base station via a downlink resource, sends the downlink data to a user equipment (UE) via an uplink resource, receives uplink data from the UE via the uplink resource, and sends the uplink data to the base station via the uplink resource. The apparatus also determines at least one of an observed downlink signal-to-interference-plus-noise ratio (SINR) or an observed uplink interference. The apparatus then broadcasts a relay availability based on the determination that the at least one of the downlink SINR observed is greater than a first threshold or the uplink interference at the relay is less than a second threshold.

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, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be an eNB. The eNB informs UE(s) of a change in at least one of a first configuration for transmission of ACKs/NACKs by the UE(s) for DL transmissions received by the UE(s) or a second configuration for reception of ACKs/NACKs by the UE(s) for UL transmissions sent by the UE(s). The eNB indicates to the UE(s) one or more resources in which the UE(s) is to transmit the ACKs/NACKs for the received DL transmissions or is to receive the ACKs/NACKs for sent UL transmissions. The eNB indicates to the UE(s) a subset of the DL transmissions to the UE(s) for which the UE(s) is to transmit the ACKs/NACKs or a subset of the UL transmissions by the UE(s) for which the UE(s) is to receive the ACKs/NACKs.
