摘要: In this paper, we investigate the physical layer security issue in a cellular network with full-duplex (FD) base station and multiple uplinks downlinks. We provide novel cooperative jamming mechanism order to enhance secrecy performance for investigated scenario. The total bandwidth is divided into resource blocks (RBs). our investigation, each uplink or downlink can acquire at most one RB, RB only be assigned downlink. formulate capacity maximization problem as joint assignment power allocation problem, then propose bipartite graph based propose-and-decide algorithm (BGPDA) solve effectively efficiently. numerical simulations verify efficiency of proposed algorithm.
