SELECTIVE DETECTION OF FEEDBACK FOR RESOURCE SELECTION

Abstract:

Aspects relate to resource selection by a first device within a wireless communication network. A second device may reserve resources for a first transmission and a retransmission to at least one third device over a direct link. If the strength of a signal received from the second device is greater than a threshold, the first device may detect feedback from the at least one third device to determine whether there will be a retransmission. If there will not be a retransmission, the first device may add to a candidate set at least one resource that overlaps with at least one of the resources previously reserved for the retransmission. If the signal strength is less than a threshold, the first device may, without detecting the feedback, add to a candidate set of resources at least one resource that overlaps with at least one of the resources previously reserved for the retransmission.
