Abstract :
In cdma2000 1xEV, each mobile station determines its data rate based on a reverse activity bit (RAB) broadcasted by the base station and a set of up/down probabilities. In this paper, we propose a new rate control scheme that allows mobile stations to choose between two optimal rates determined by the rise over thermal (RoT) constraints. The base station determines the RAB signal based on the current RoT and estimated parameters of the next frame transmission. The proposed scheme is modelled using a Markov process. Both our simulation and analytical results confirm that the proposed scheme achieves better performance than previously proposed rate assignment schemes.
