Device-to-device (D2D) communications has gradually become a promising technique to support wireless peer-to-peer services and enhance the overall spectrum utilization. In the meantime, the full-duplex communication technique has also attracted significant research interest recently. In this paper, for the first time, we employ the D2D communication concept in a full-duplex cellular network. In such...
In this paper, we investigate the physical layer security issue in a cellular network with a full-duplex (FD) base station and multiple uplinks and downlinks. We provide a novel cooperative jamming mechanism in order to enhance the secrecy performance for the investigated scenario. The total bandwidth is divided into multiple resource blocks (RBs). In our investigation, each uplink or downlink can...
This paper investigates the performance of bidirectional dynamic networks (BDN) with massive multiple input multiple output (MIMO) systems. In BDN, dynamic allocation of the number of uplink and downlink remote radio heads (RRHs) is proposed, which offers a flexible solution to balance the data traffic asymmetry without requiring the time synchronization. Intuitively, the interference between the...
In this paper, we investigate the resource sharing problem to optimize the system performance in device-to-device(D2D) communications underlaying full-duplex cellular networks. In the investigated scenario, D2D links, cellular uplinks and cellular downlinks are permitted to reuse the same spectrum resources under efficient interference control, leading to a more complicated interference relationship...
