英文摘要： For the needs of a large number of high-speed downlink data services in the future of systems with intelligent terminals, we research for data transmission by cellular D2D collaborative of Any-cast mixed services, to achieve efficient wireless resource utilization and reliable data reception. Based on wireless multicast, unicast and broadcast regarded as the special cases in the researches. We study hypergraph-based theory of random walk algorithm to establish a stable cooperative clustering model; on the basis, study cooperative transmission strategies and resource dynamically allocating based on cognitive D2D links in MIMO-OFDM systems, and adopt collaborative Q-learning algorithms among D2D terminals to reduce the computation complexity and solve the problem of multicast cooperative transmission and packet loss repair; using dynamic MIMI-OFDM beamforming optimization algorithm to achieve multicast diversity/multiplexing tradeoff, improve reliability while improving throughput; in the case of heavy traffic load of Any-cast mixed services, study sub-carrier resource random scheduing algorithm by smoothly upgrade-downgrade QoS of unicast users, based on mulitcast groups alliance cooperative and competitive game with the conditions of QoS and GoS performance, in order to admit the maximum number of users while im
