Research on the enhancement technology based on the 5G wireless access and wireless backhaul integration by Feng BI

“…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.…”
