基于FAD天线的TD-LTE与TD-SCDMA协同优化方法研究

摘要

In 2013, China Mobile will face pressure of network plan and optimization of 2 hundred thousand of TD-LTE eNode B. According to the situation of TD-LTE and TD-SCDMA with unique FAD smart antenna, method of broadcast beamforming was proposed with different beamforming parameters. Then RF coupling degree of two system was reduced, so independent optimization was realized, ifnally pipeline of coordination optimization was given.%2013年中国移动面临着全网20万站点的建设规模，TD-LTE网络规划和网络优化面临很大压力。本文针对TD-LTE与TD-SCDMA共FAD智能天线场景提出了智能天线广播波束成形方法，采用独立的广播波束成形参数，降低两系统的RF耦合度，最终做到两系统独立优化，最后给出两系统协同优化方法与流程。
