摘要

随着通信业务需求日益增长，在构建5G网络时需要重点考虑网络覆盖范围、频谱效率以及运营商的部署运营成本等因素，网络中引入的中继节点可以解决这些问题。但中继节点存在收发自干扰，时分复用虽然可以避免自干扰，但将增加端到端业务时延。为了更好地解决这些问题，重点从无线接入和无线回程之间的资源复用方式、节点定时、保护频带、性能仿真验证方面进行了一体化增强技术研究。提出的一体化增强技术方案既避免了中继节点自干扰，也保证了业务时延需求和用户感知吞吐量。

Abstract

With the increasing requirements for communication services

it is necessary to focus on the factors such as the network coverage

the spectrum efficiency and the deployment and operation cost of operators when building 5G networks.The relay node introduced into the network can solve these problems.However

the relay node has self-interference.Although time-division multiplexing can avoid self-interference

it will increase the end-to-end service delay.In order to better solve these problems

the integrated enhancement technology researches were focused on the aspects of the resource multiplexing mode

the node timing

the guard band and the performance simulation verification between the wireless access and the wireless backhaul.The proposed integrated enhancement technology schemes not only avoid the self-interference of relay node

but also ensure the requirement for the service delay and user perceived throughput.
