论文摘要
由于5G和超越细胞网络的小细胞快速致密化，因此很难将有线的高带宽连接到每个小细胞基站，尤其是在缺乏用于纤维部署基础设施的较旧的大都市地区。因此，MMWave Wireless Backhaul被认为是一种具有成本效益和灵活的替代方案，具有支持满足回程交通需求所需的高速传输的潜力。但是，维持高网络的生存能力非常重要，因为基于MMWave通信的网络容易受到短期障碍或不可预见的事件引起的节点故障的影响。因此，为了实现强大的MMWave回程网络，几项作品建议在路边环境中采用三角波拓扑，这可以消除回程链接之间的相互干扰，并为阻塞效应提供鲁棒性。基于这种新颖的拓扑结构，我们研究了一种阻滞类型检测方案，该方案对阻塞效应迅速反应，并有助于各种路径重新配置方法。
Due to the rapid densification of small cells in 5G and beyond cellular networks, deploying wired high-bandwidth connections to every small cell base station is difficult, particularly in older metropolitan areas where infrastructure for fiber deployment is lacking. For this reason, mmWave wireless backhaul is being considered as a cost-effective and flexible alternative that has potential to support the high-rate transmission needed to accommodate backhaul traffic demands. However, maintaining a high network survivability is extremely important since networks based on mmWave communication are susceptible to short-term blockages or node failures caused by unforeseen events. Therefore, to realize a robust mmWave backhaul network, several works propose to adopt a triangular-wave topology in roadside environments, which can eliminate the mutual interference among backhaul links, and provide robustness to blockage effects. Based on this novel topology, we investigate a blockage type detection scheme, which reacts to blockage effects quickly and assists in various path reconfiguration approaches.
