摘要
针对5G网络千兆级吞吐量的业务需求,研究两种典型的超密集网络架构的无线回程解决方案。在这两种回程网路架构基础上,提出超密集网络中设备到设备通信的高效传输协议设计。用户设备间可通过多跳中继实现直接通信而无需宏基站的转发。根据超密集网络的毫米波覆盖特性,提出多用户通信的毫米波动态带宽改进机制。仿真和分析结果表明,所提方案与传统通信方案相比,降低了网络的误码率,提升了系统的吞吐量,并且有效改善了通信信道的能效。
Focused on the requirement of Gigabit level throughput of 5G networks,two typical backhaul solutions in ultra-dense networks architectures were studied. Based on these two backhaul network architectures, an efficient transmission protocol design for device-to-device communication in ultra-dense networks was proposed. The user equipment can realize direct communication through multi-hop relay without the need of macro base station forwarding.According to the millimeter-wave coverage characteristics of ultra-dense networks,a millimeter-wave dynamic bandwidth improvement mechanism for multi-user communication was proposed. Simulation and analysis results show that compared with the traditional communication scheme,the proposed scheme reduces the bit error rate of the network,improves the system throughput,and effectively improves the energy efficiency of the communication channel.
