对于当前TD?LTE与TD?SCDMA系统邻频共存的情况，由于两者皆为TDD系统，所以TD?LTE必须与TD?SCD?MA系统的子帧配比兼容以避免系统间干扰；给出了两者共存时兼容的子帧配比，研究了此子帧配比下TD?LTE的两种特殊时隙配比方案SSP5与SSP6，并从下行资源利用情况、单小区下行峰值吞吐量、基站可规避干扰距离等方面将两方案做了对比分析，指出SSP6能够更好地利用系统的下行资源，有利于提升系统容量。

When TD?LTE system coexists with TD?SCDMA system at F and A bands,because both of them are TDD sys?tem,the sub?frame configuration of them must be compatible to avoid the interference between the two systems. The compatible sub?frame configuration is given in this paper. The two special time?gap configurations SSP5 and SSP6 of TD?LTE in this sub?frame configuration are researched. The downlink resource utilization,downlink peak throughput /cell,interference?free distance of SSP5 and SSP6 configurations are analyzed in this paper. The results indicates that SSP6 is better than SSP5 in improvement of system capacity.
