A distributed fixed-step power control algorithm for mobile cellular systems

A distributed fixed-step power control algorithm is presented. It is a simple feedback adjustment algorithm using only local information. In the ideal case where there is no power constraint, it is guaranteed that existing users will not be dropped due to admission of new users. When the constraint on maximum power is imposed, it is shown by simulation that the dropping probability is much lower than the blocking probability. Besides, its convergence property is demonstrated and the issue of power quantization is addressed.
