多媒体业务的一个显著特点就是上下行链路之间的业务不均衡。TDD模式的移动通信系统很好地解决了这个问题。而对于CDMA/TDD蜂窝系统来说 ,使得系统资源利用率最高的时隙分配方案是必需的。提出了一种CDMA/TDD多媒体业务系统中的最优时隙分配方法 ,分析了在系统干扰的约束下 ,这种时隙分配方法的可行性和性能 ,并且指出了最优时隙分配不仅受小区业务不均衡因子的影响 ,而且要受小区负载不平衡程度的影响。
A notable feature of multimedia services is the business imbalance between the uplink and the downlink. TDD mode of mobile communication system is a good solution to this problem. And for the CDMA / TDD cellular system, make the system resource utilization of the highest slot allocation scheme is necessary. An optimal time slot assignment method in CDMA / TDD multimedia service system is proposed. The feasibility and performance of this slot assignment method are analyzed under the constraints of system interference. It is pointed out that the optimal time slot assignment is not only affected by Cell business imbalance factor, but also affected by the degree of cell load imbalance.
