基于多波束基站天线的扩容方案探讨

Discussion on expansion scheme based on multi-beam base station antenna

当今的2G、3G、4G系统长期并存使用,在站址资源和频谱资源双重紧张的前提下,有效地解决通信容量不足、覆盖易出现盲区等问题迫在眉睫;多波束天线在缓解站址资源和提高系统容量方面极具优势。基于上述背景,从实际出发,在移动通信领域展开了基于多波束天线的扩容方案研究,创新性地提出了一种可实现天线多波束功能的波束成形网络,分析了该多波束天线在工程应用中的覆盖、RSRP、SINR、切换和重叠覆盖度等指标,验证了该方案能有效地提升系统容量,提高用户感知。

Today,2 G,3 G,and 4 G systems coexist for a long time.Under the premise of double stress on site resources and spectrum resources,it is extremely urgent to effectively solve the problems of insufficient communication capacity and easy coverage of blind spots.Multi-beam antennas have great advantages in mitigating site resources and improving system capacity.Based on the above background and the actual situation,the research on the expansion scheme based on multi-beam antenna was carried out in the field of mobile communication.A beamforming network that could realize the multi-beam function of the antenna was proposed innovatively.The multi-beam antenna was analyzed in engineering application.The coverage,RSRP,SINR,handover and overlapping coverage indicators verify that the scheme can effectively improve system capacity and improve user perception.
