本文首先基于补充信道分配方法和 cdma2 0 0 0 1 x高速分组数据业务吞吐量的关系 ,分析了共享补充信道方式的必要性。然后 ,针对其实现过程中所要涉及到的几个关键问题——补充信道的活动集切换、分组数据调度算法、功控模式和系统的帧偏移分配等进行了讨论 ,并分别提供了相应的解决方案 This paper first analyzes the necessity of sharing supplementary channel based on the relationship between complementary channel allocation and cdma2 0 0 0 1 x high-speed packet data service throughput. Then, several key issues to be involved in its implementation, such as active set switching of complementary channels, packet data scheduling algorithm, power control mode and system frame offset assignment, are discussed and the corresponding solution
