Device-to-device (D2D) multicast communication is a useful way to improve the communication efficiency of user equipments which are located close to each other. In this paper, the frequency resource sharing problem of D2D multicast communications underlying single frequency network (SFN) system is investigated. Firstly, to avoid the interference between D2D and cellular communication and without consuming...
Device-to-Device (D2D) multicast underlaying a cellular infrastructure has recently investigated. In this paper, we propose a new interference management scheme for D2D multicast to increase the overall capacity and improve resource utilization. The proposed scheme includes two steps. First, in order to mitigate the interference from D2D multicast transmission to cellular networks (CNs), a dynamic...
Multicast beamforming is a challenging problem in wireless networks due to different channel conditions of users. The data rate of a multicast group is dominated by the achievable data rate of the worst case user. Beamforming in multicasting system can provide better performance by maximizing the minimum Signal to Noise Ratio over all receivers in a multi-antenna system. In this paper, we focus on...
