cdma2000-1x中共享补充信道方式的研究与实现

Research and Implementation on Shared SCH of cdma2000-1x

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 。

Based on the relationship between the SCH assignmentpolicies and the throughput of high speed packet data service in cdma2 0 0 0 1 x systems,we analysis the advantage of Shared SCH.Then,we discuss several crucial problems in the implementation of Shared SCH,such as Switching the SCH active set,packetdata scheduler algorithms,power control mode,assigning frame- offset,and so on.And,solutions to them are presented in this paper.
