密集城区5G广播波束配置策略研究

Research on 5g broadcast beam configuration strategy in dense urban area

5G移动通信关键技术在于波束赋形,以及波束多样性带来的垂直角度覆盖增益,配置不同的波束赋形权值,小区水平和垂直覆盖增益各不相同。5G TDD 3.5G频段分配17种波束配置模式,开网默认S0模式垂直波宽小、电子下倾调整范围小、电子方位角不能调整、覆盖局限性大。通过结合城区地域特色结合理论模型搭建、仿真支撑、路测数据验证、室内CQT验证、系统指标同步评估、验证结果合理性整体评估的方法,给出适合城区的5G小区广播波束配置组合模式,提升室内外整体覆盖能力。

The key technologies of 5g mobile communication are beamforming,vertical angle coverage gain caused by beam diversity,configuration of different beam configuration weights,horizontal and vertical coverage gain of cell,etc.rent Band 5g TDD 3,5g is divided into 17 beamforming modes.By default,SO mode has smaller vertical wave width,smaller downward tilt range,non adjustable electron azimuth and larger Cover.Based on the regional characteristics of City,This paper presents a 5G cell broadcast beam splicing model suitable for City.Through the establishment of theoretical model and simulation support,the comprehensive coverage ability inside and outside the district is improved.Road survey data verification,indoor CQT verification,system index synchronous evaluation,and comprehensive evaluation of rationality of results.
