Abstract

An efficient receiving status feedback in multicast communications can improve the system performance considerably. In this paper, we propose a novel compressed hybrid automatic repeat request (HARQ) mechanism for the reliable multicast services in the cellular network controlled Device-to-Device (D2D) communications. Closely located D2D cluster devices transmit the acknowledgement and negative acknowledgement (ACK/NACK) message to a cluster head through D2D links directly, after that the cluster head feeds back the whole D2D cluster receiving status using 2-bit ACK/NACK to the cellular network. Performance analysis and numerical simulation results reveal that the proposed HARQ feedback mechanism is better than the conventional D2D multicast mechanisms in terms of the error probability and signaling overhead.
