5G超稠密网络中基于多连通性的移动性增强

发布时间：2023-04-19 21:22

　　未来无线网络需要满足高吞吐量的3D视频数据,虚拟现实(VR),社交网络,电子银行,互动游戏等对视频服务爆炸式增长的需求。随着小小区和电子设备的增多,将面临更多的干扰,这些干扰将导致的切换失败。网络密集化缩小了基站(BS)的覆盖范围,并减少了每个BS服务用户数量,从而提高了网络容量。鉴于全球人口在连接、共享性和速率方面的显著增加,UDN(超密集网络)在解决高速数据速率需求方面发挥重要作用。在论文中,分析了基于本地锚节点的双连接结构。使用随机几何工具分析了超密集网络C/U分离双连接结构的下行链路蜂窝网络移动感知模型。然后使用所开发的模型来量化移动性对具有和不具有双连接结构的密集部署增益的影响。数值结果证明了双连接可以提升移动性性能。
