Abstract

In this paper, we consider the problem of downlink frequency-time slots and power allocation to the users in an IEEE 802.16 band-AMC system. The allocation is subject to proportional rate constraints and total transmission power. A three-step heuristic scheme whose main step uses an unbalanced transportation problem is presented. The proposed scheme is shown to be a good compromise between the greedy-oriented schemes and a Proportional Rate Constraints (PRC) scheme introduced in the literature. The computational complexity of the proposed scheme allows it to be implemented in real-time with off-the-shelf hardware.
