摘　　要：采用转换点配置法,提出TD-LTE在同半帧及异半帧场景下的特殊时隙配置,能够很好地规避与TD-SCDMA的交叉时隙干扰。首次提出单GP优化法,无论是常规CP还是扩展CP,均尽可能地压缩同半帧和异半帧配置下的GP时隙,有效提高了特殊时隙的利用率,非常有利于解决TD-LTE网络建设中的系统规划和优化问题。Due to the same different sub-frame configuration of TD-LTE, it puts forward a solution to avoid the intercept interference with TD-SCDMA. As a result, a new single GP optimization method was given to improve the utilization efficiency of special timeslot for TD-LTE system. Among this method, GP timeslot was compressed as far as possible regardless of normal CP and extended CP, which will give a strong guide to solve the problem in network planning and optimization.
