Radio Link Protocol Based SCH Power Control in cdma2000

Fast closed-loop power control is widely used in code division multiple access (CDMA) systems to ensure a minimum received signal quality for circuit-switched services, foremost among which is voice. However, third-generation wireless systems such as cdma2000 often accommodate multiple concurrent services with different quality-of-service constraints. Nevertheless, typical closed loop power control methods still are biased towards only one service. In the cdma2000 reverse link, concurrent services may be accommodated over code-multiplexed channels (namely the fundamental channel FCH and supplemental channel SCH). This paper provides a method for optimizing power control for the SCH in the presence of an FCH when a radio link protocol (RLP) is used. This method achieves less transmission power in most of cases, as well as less RLP delay
