Performance Evaluation of a Massive MIMO Intercell Interference Prediction Method

Abstract

This paper presents a massive MIMO intercell interference prediction method. Despite the deployment of 4G in Lagos, Nigeria urgently needs to upgrade to a 5G network in order to quickly meet the demand for a wide range of multimedia services. The downstream and uplink data capacities of 5G networks are no less than 300 and 60 Mbps, respectively, with a penetration rate of at least 95% at any moment of time; Based on the local data of Huawei Nigeria Co., Ltd. in Lagos, Nigeria, a 5G intercellular interference prediction scheme based on LTE performance index is proposed. The performance of the currently deployed LTE network is evaluated using performance metrics such as uplink and downlink capability, and a possible intercellular interference mitigation technology is recommended for the deployment of 5G network in Lagos. The identified key performance indicators include air simulation, carrier jamming to noise ratio, RLC peak throughput, coverage probability, and map-based model. The static inter-cell PFR algorithm has good CINR coverage for low CINR values (near the cell edge), while the Hard FFR algorithm has good CINR coverage for high CINR values (near the central region). While large-scale antenna systems will allow for all-digital array architecture, which helps to maximize beamforming flexibility, But the cost is a major challenge with the evolution of the pilot affecting pollution with general SINR constraints, limits being able to create the correct beam pattern using a large number of elements, it is necessary to adjust the phase and amplitude of each antenna unit and configure the antenna beam to control full digital processing and redistribution. The relatively poor performance in Fig. 2, Fig. 3 and Fig. 4 indicates that there is no coordination algorithm in the network, which also affects the network OTA performance. In summary, in order to improve the spectrum efficiency and system throughput, it is recommended to use the static intercell interference technology for future deployment of the 5th generation system in Nigeria.
