与传统的2G/3G技术相比，TD-LTE采用同频组网的频率复用方式，其小区边缘用户覆盖同小区间干扰存在一定的矛盾。目前中国移动采用较高频点进行组网造成深度覆盖能力不足，使得其网络质量控制和提升存在一定的困难。文章提出一种干扰小区探测方法解决网络结构中的重叠覆盖，并分析采用微站结合宏站组成分层网解决深度覆盖问题，从而有效提升TD-LTE网络质量。
與傳統的2G/3G技術相比，TD-LTE採用同頻組網的頻率複用方式，其小區邊緣用戶覆蓋同小區間榦擾存在一定的矛盾。目前中國移動採用較高頻點進行組網造成深度覆蓋能力不足，使得其網絡質量控製和提升存在一定的睏難。文章提齣一種榦擾小區探測方法解決網絡結構中的重疊覆蓋，併分析採用微站結閤宏站組成分層網解決深度覆蓋問題，從而有效提升TD-LTE網絡質量。

Wireless network planning is one of the most significant factors in mobile communication network construction, which directly affect the net-work performance. For the reason that TD-LTE em-ploys full frequency reuse mode, there is contradic-tion between the user cell edge throughput and the inter cell interference compared with traditional 2G and 3G network. Meanwhile, the depth coverage abil-ity is insufficient because of employing high frequen-cy band, which makes the network quality control difficultly. One method is presented in this paper to solve the overlapping interference problem in net-work structure and one solution is used to enhance the depth coverage capacity by hierarchical network.
