Energy-Efficient Downlink Power Control and Scheduling for CDMA Non-Real Time Data

The performance of CDMA systems highly depends on the success in managing interference arising from both inter-cell and intra-cell transmissions. Interference management in terms of power control has been widely studied. In this paper we consider non-real time data services, where in addition to power control, there is the possibility of scheduling intra-cell transmissions. One such schedule is to use time division so that users transmit in a one-by-one fashion within each cell. We combine this form of scheduling with a suggested distributed power control algorithm for the inter-cell interference management. We show that the algorithm converges to a power allocation that supports the non-real time data users with the minimum power while meeting requirements on average data rate.
