Abstract

We consider power control for voice users in a wideband CDMA wireless network. We investigate admission control policies that base a new call admission decision not only upon available capacity but also upon the required downlink transmit power and upon the user's willingness to pay. We assume that each voice user has a utility function that describes the user's willingness to pay as a function of downlink SINR. The network is assumed to desire to either maximize total utility of all users or total revenue generated from all users. We present a numerical study of a single cell. We display the optimal power allocation to each user, as a function of the geographical distribution of users, for a selection of different utility function distributions. We demonstrate how prices per code and per unit transmitted power can be used to achieve the optimal power allocation in a distributed fashion, and the variation of these prices with system load.
