摘要:
A method for operating a user equipment (UE) in a UE group including at least two UEs includes receiving, from a communications controller, network resources information about an allocation of a first set of network resources to the UE group and a transmission indication, where the transmission indication indicates that the UE is selected to transmit in a second set of network resources that is a subset of the first set of network resources. The method further includes transmitting, to other UEs in the UE group utilizing a direct mobile communications (DMC) link associated with the communications controller, a first message including a control indicator in a first subset of the second set of network resources, the control indicator indicating scheduling information for a second subset of the second set of network resources.

An embodiment of a system for operating a communications controller for a group of user equipments engaged in a direct mobile communication (“DMC”) link in a wireless communications system is provided. The communications controller is configured to allocate a set of subframes to the group of UEs for the DMC link, signal the set of allocated subframes to the group of UEs, and signal a length of a sliding window to the group of UEs. In an embodiment, ACK/NACK feedback for communications over the DMC link is aggregated according to the length of the sliding window, and 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. In an embodiment, the length of the sliding window is a number of subframes.

An embodiment of a system for operating a communications controller and a user equipment in a wireless communications system is provided. The communications controller is configured to allocate a first set of subframes to a group of UEs for a DMC link, allocate a second set of subframes to a particular UE in the group of UEs, transmit a first message including information about the first set of subframes to the group of UE, and transmit a second message including information about the second set of subframes to the particular UE. The second set of subframes is a subset of the first set of subframes, and information about the second set includes subframes in which the particular UE may transmit to other UEs in the group of UEs. Subframes in the first set not in the second set are allocated for reception by the particular UE.
