典型场景下5G天线波束权值研究

Research on 5G Antenna Beam Weight in Typical Scenarios

5G NR系统采用波束赋形技术。不同权值赋形的广播波束,增强不同组网场景下广播信道、同步信号的覆盖范围,更好地匹配小区覆盖范围和用户分布。根据不同场景选择适合自身覆盖需求的波束配置方案,能够解决当前小区覆盖能力有限以及受周围环境干扰等问题,适用于不同组网场景。基于此,结合实际场景问题,深入探究基站的下倾角、高度以及距离与需要覆盖区域的高度和宽度之间的关系,匹配出适配的波束覆盖方案,并给出典型场景下5G权值建议。

The 5G NR system adopts beam shaping technology.Broadcast beams with different weights can enhance the coverage of broadcast channels and synchronization signals in different networking scenarios,and better match the cell coverage and user distribution.Select a beam configuration scheme suitable for its own coverage requirements according to different scenarios,which can solve the problems of limited coverage capacity of the current cell and interference from the surrounding environment,and is suitable for different networking scenarios.Based on this,combined with the actual scene problems,the relationship between the inclination,height,and distance of the base station and the height and width of the area to be covered is deeply explored,and the adaptive beam coverage scheme is matched,and the 5G weight recommendations in typical scenarios are given.
