摘要
由于大规模阵列天线和波束赋形等新技术的应用,5G网络在覆盖能力、性能要求和应用场景等方面相对于4G存在明显差异,传统的4G重叠覆盖标准已经不再适用。本文基于实际测试结果,分析了5G重叠覆盖对用户感知的影响,并针对用户感知提出了基于速率损失的5G重叠覆盖标准,以及基于感知速率和电平区间的5G重叠覆盖标准。根据5G网络的现状和发展情况,可选择合适的5G重叠覆盖标准指导结构优化工作。
Due to the application of new technologies such as large-scale array antennas and beamforming,5G networks are signifi cantly diff erent from 4G in terms of coverage capabilities,performance requirements,and application scenarios.The traditional 4G overlapping coverage standards are no longer applicable.Based on actual test results,this paper analyzes the impact of 5G overlap coverage on user perception,and proposes 5G overlap coverage standards based on rate loss and 5G overlap coverage standards based on perceived rate and level range for user perception.According to the current status and development of 5G networks,suitable 5G overlapping coverage standards can be selected to guide structural optimization.
