Research on Reverse Traffic Channel Rate Control Technology of
CDMA2000 1xEV-DO Revision A System
摘要 首先描述了反向链路的设计原理:为每个MAC流提供不同的QoS控制是通过终端处的分布式速率选择和基站处的资源集中控制相结合的方法来实现的,而整个主线是由参数RoT-RAB-T2P-TxT2P构成闭环控制。接着从数学模型的角度较为详细地介绍了反向业务信道速率控制机制的具体实现过程,并且从理论上说明了控制机制会明显提高反向速率。

Abstract: Firstly describes the design principle of reverse link,and educes that providing
diverse QoS control to each MAC flow is based on the combination of distributed rate
selection at ATs and the centralized resource control at BSs,and the whole masterstroke
is the closed-loop control which is composed of parameters RoT-RAB-T2P-TxT2P.And then
particularly presents the implementation process of reverse traffic channel rate control
mechanism by maths model,and explains that the control mechanism can improve
reverse rate according to the theory.
