In this paper, we present an approach for power allocation to maximize the effective system throughput with pricing on the downlink in a CDMA system. We present a pricing policy and obtain the optimum powers for the users to maximize the effective system throughput incorporting this pricing policy.We also study the asymptotic behavior of the system (i.e., when the number of users and the available bandwidth are large). We show that in such a system, all users obtain equal SIR at the optimum point irrespective of their locations and processing gains. We also derive an expression for the maximum asymptotic spectral efficiency.
