Abstract:
1. A method of operating a communications controller for a direct mobile communication (DMC) link for a group of user equipments (UEs), the method comprising: allocating a set of subframes to the group of UEs for the DMC link; signaling the set of allocated subframes to the group of UEs; and indicating a length of a sliding window to the group of UEs for UEs of the group of UEs to aggregate acknowledgment and negative acknowledgement (ACK/NACK) feedback for communications over the DMC link according to the length of the sliding window, wherein the aggregated ACK/NACK feedback retains individual ACK and NACK information; wherein the length of the sliding window is determined from the allocated set of subframes, and wherein the ACK/NACK feedback for the communications over the DMC link is determined independently from ACK/NACK feedback for cellular transmission between the communication controller and the group of UEs.
