Abstract

This paper investigates the situation where a group of terminals can be simul- taneously connected to several base stations using distinct technologies on non- overlapping frequency bands. We introduce and solve the problem of optimal power allocation (in the sense of the ergodic sum-rate) for the terminals in the uplink, using three types of receivers: the optimum receiver, minimum mean square error and matched filters. Key results from random matrix theory allow us to solve the corresponding optimization problems. Simulations validate our approach and illus- trate the performance gain obtained by using several technologies simultaneously instead of one at a time.
