Claim:
1. A method, comprising: determining, by an acknowledgment device in a device-to-device cluster, at least a first modulation and coding scheme for a first retransmission mode, the first retransmission mode based on at least a first set of parameters comprising the first modulation and coding scheme; determining, by the acknowledgement device, at least a second modulation and coding scheme for a second retransmission mode, the second retransmission mode based on at least a second set of parameters comprising the second modulation and coding scheme, wherein the acknowledgement device decodes data from a base station correctly, wherein the first set of parameters and the second set of parameters are determined for subsequent transmission of the data between the acknowledgement device and at least one non-acknowledgement device in the device-to-device cluster, wherein the at least one non-acknowledgement device does not decode the data from the base station correctly; reporting, by the acknowledgment device and before a selection by the base station, at least the first set of parameters and the second set of parameters to the base station; and multicasting, by the acknowledgment device and in response to the selection by the base station, the data according to the first retransmission mode or the second retransmission mode to the at least one non-acknowledgement device, wherein the selection is between the first set of parameters and the second set of parameters.
