An integrated power and rate control algorithm is proposed to satisfy the requirements of both user's data rate and signal quality. This algorithm lets only one representative user in each cell participate in the distributed power control and assigns the power levels to other users according to some constant power ratios. In addition to reducing the computational complexity, the proposed algorithm also gains larger throughput for the same number of iterations and finds a feasible power set faster than the other algorithm does.
