A packet scheduling algorithm based on signal-to-interference-and-noise ratio (SINR) and user priority is here presented for the down-link of distributed broadband wireless systems (DBWS). The approach consists of simultaneously optimizing the set of scheduled users and their transmit power levels with the aim of maximizing the number of scheduled users per joint processing area (or cell) and also satisfying in the best possible way their target requirements (SINR and user priority). In recognition that maximum SINR schedulers suffer from the problem of starvation, the concept of user priority is introduced in our algorithm in order to improve the
performance of previously unfavoured users (e.g., users that are far away from the radiation nodes). Performance analysis in terms of packet throughput and processing complexity demonstrates the benefits of the proposed scheme.
