Full-duplex (FD) networks promise nearly doubled spectrum efficiency for single links with beyond 100 dB self-interference cancellation capability. However, the performance of FD networking is not that straightforward, as there will be several new types of interference introduced. Hence, it is critical to exploit some radio resource management techniques to combat the annoying interference and inevitably needs to reserve part of radio resources in HD mode to obtain the essential auxiliary information. It is naturally to ask which physical channels and signals could be left in the FD mode and how much system gain FD cellular networks could bring? In this paper, we try to answer these questions. We first propose the feasibility to leave one kind of physical channels or signals in the FD mode and then highlight some potential resource management schemes. We will also demonstrate the system gain of FD networks by leveraging our proposed design and the management techniques. Our simulation results show FD communications leads to promising performance improvement.
