Research on Mixed Planning Method of 5G and LTE

Abstract

5G will enter the stage of large-scale commercial deployment. It can be said that "quick deployment of 5G network" is the choice that telecom operators must make now. Due to the need to seize the 5G competition and the smooth evolution of the architecture, most domestic and foreign operators currently adopt the NSA solution. However, how to implement 5G network deployment can achieve accurate delivery of network resources and avoid waste of network resources and investment costs in 5G network deployment. In view of this problem, at the same time, the current 5G is still in the early stage of development, and there is no experience of large-scale planning and deployment. This paper proposes a hybrid planning method of 5G and LTE under the NSA mode. Firstly, the analysis introduces 5G network performance, NSA networking mode, system network planning indicators, and summarizes 5G network planning indicators, business forecasting, frequency planning, capacity planning and so on. Then, through the uplink and downlink budget, the coverage of 5G and LTE is determined. Finally, the grid analysis method is used to deploy the 5G network, and the simulation results are analyzed. The simulation results show that the proposed method can maintain the existing network structure and reduce the cost of network construction, so that operators can quickly deploy 5G on existing LTE sites, which has important guiding significance for the construction and deployment of the previous 5G network.
