In the scenario of multicast D2D communication underlaying a cellular network,a new optimization scheme of clustering strategy and resource allocation is proposed aiming at reducing the co-channel interference caused by channel reuse and increasing the limited capacity of multicast D2D communication caused by the worst channel quality in the cluster. We formulate the optimization problem for maximizing the total system capacity to ensure the minimum SINR for cellular and D2D users,but it is difficult to find the optimal solution. We decompose the problem into two sub-problems, power control sub-problem and clustering and channel allocation sub-problem, to find the sub-optimal solutions. Based on k-medoids clustering algorithm,a channel quality-based clustering algorithm is proposed to improve the multicast D2D capacity. Then, through the joint clustering and channel allocation strategy, the co-channel interference is reduced. Simulation shows that the proposed CQCA significantly improves the minimum throughput of multicast D2D users and results in a great improvement in the total system throughput.
