摘要:

超密集毫米波蜂窝网络中的移动用户比传统网络中更频繁地经历切换事件,这导致由于阻塞而增加的服务中断时间和性能下降。多连接技术已经被提出来解决这个问题,它也扩展了毫米波通信的覆盖范围。在本文中,我们提出了一种基于双连接的切换方案,移动UE的环境中,他们同时与两个毫米波小区连接,以克服频繁的切换问题。该方案允许移动UE根据测量的SINR在两个毫米波连接之间选择其服务链路,然后相应的基站可以将重复的分组转发给UE。我们比较我们的双连接为基础的计划与传统的单连接为基础的计划,通过ns-3模拟。仿真结果表明,该方案能显著降低切换速率和切换时延.因此,我们认为,双连接为基础的计划,帮助移动用户实现他们需要在超密集的蜂窝环境中的性能目标。

英文摘要:

Mobile users in an ultra-dense millimeter-wave cellular network experience handover events more frequently than in conventional networks, which results in increased service interruption time and performance degradation due to blockages. Multi-connectivity has been proposed to resolve this, and it also extends the coverage of millimeter-wave communications. In this paper, we propose a dual-connection based handover scheme for mobile UEs in an environment where they are connected simultaneously with two millimeter-wave cells to overcome frequent handover problems. This scheme allows a mobile UE to choose its serving link between the two mmWave connections according to the measured SINRs and then the corresponding base stations may forward duplicate packets to the UE. We compare our dual-connection based scheme with a conventional single-connection based scheme through ns-3 simulation. The simulation results show that the proposed scheme significantly reduces handover rate and delay. Therefore, we argue that the dual-connection based scheme helps mobile users achieve performance goals they require in ultra-dense cellular environments.
