| 摘 要： | 在TD-SCDMA系统中,由于对上下行不对称业务的需求,使得不同小区间的上下行切换点不同,因此会产生严重的小区间干扰(基站和基站间干扰)。提出一种基于移动台位置的抗基站间干扰的动态信道分配(DCA)的改进方案,它通过增大交叉时隙的空间隔离度和减少交叉时隙的使用机率来改善基站间的相互干扰,同时使每个时隙的用户空间分布更加均匀,最大化提高系统容量,改善非对称业务下系统的整体性能。

| Abstract: | In the TD-SCDMA system, the demand of asymmetrical traffic between the up-link and the down-link in different Base Stations and the consequent handoff time difference in different cells will cause serious inter-cell interference. A mobile station position based dynamic channel allocation scheme is proposed to decrease interference between base stations. It is enabled by increasing the space isolation between cross timeslots and decreasing the number of cross slots while achieving a more uniformed spacial distribution in each time-slot, maximizing system capacity, and improving the overall system performance of asymmetrical traffic. |
