The last decade brought major changes in cellular networks, as explosive growth in data traffic and users capacity demands requires more and more network capacity and backhaul capability. Future wireless technologies have been developing to tackle these challenges. One of the current emerging technologies is the device-to-device (D2D) communications technology. This enables connection within cellular systems between two user equipments (UEs) to communicate with each other directly by reusing cellular radio resources. In this case, D2D is able to offload data traffic from central base stations (BSs) and significantly improve the spectrum efficiency of a cellular system, and hence this is the key technology for the future generation mobile communication systems. With a super greatly increased traffic rate from huge bandwidth of mmWave communications, for higher energy efficiency this should be mitigated. This paper, propose an energy-efficient multicast scheduling scheme, referred to as EMS algorithm, which utilizes both D2D network and concurrent transmissions to achieve more energy efficiency. In this algorithm, a D2D path planning algorithm establishes multi-hop paths between D2D and a concurrent EMS allocates the network links on the D2D paths into different pairs. Then, the transmission power of links is managed by the power control method. Simulation of EMS with various system parameters describes the best performance of algorithm in terms of energy as compared with the state-of-the art methods.
