论文摘要
尽管在蜂窝网络中，全双工和动态时间划分的双工希望提高了频谱效率，但迄今为止，其潜力受到增加的干扰挑战。虽然先前的研究表明，自我干扰可以抑制到足够的水平，但我们表明，两种复式模式的交联干扰，尤其是从基站到基站，是多细胞网络中的剩余挑战，从而限制了上行链路性能。使用低复杂性的波束形成技术，我们表明可以减轻这种干扰，并且全双工和动态的时间划分双工可以大大增加多细胞网络的容量。我们的结果表明，如果我们可以在全双工中控制交叉链接干扰，那么我们几乎可以将多单元网络容量和用户吞吐量加倍。因此，本文中的技术具有潜力，可以使全双工平滑地引入细胞系统。
Although in cellular networks full-duplex and dynamic time-division duplexing promise increased spectrum efficiency, their potential is so far challenged by increased interference. While previous studies have shown that self-interference can be suppressed to a sufficient level, we show that the cross-link interference for both duplexing modes, especially from base station to base station, is the remaining challenge in multi-cell networks, restricting the uplink performance. Using beamforming techniques of low-complexity, we show that this interference can be mitigated, and that full-duplex and dynamic time-division duplexing can substantially increase the capacity of multi-cell networks. Our results suggest that if we can control the cross link interference in full-duplex, then we can almost double the multi cell network capacity as well as user throughput. Therefore, the techniques in this paper have the potentiality to enable a smooth introduction of full-duplex into cellular systems.
