Summary: 
There exists an optimum power assignment, which can be obtained by solving a set of linear equations, for multi-cell CDMA networks. According to the direct method, we have to measure all the link gains to solve these linear equations. We propose in this paper an indirect method which allows each base station to only measure the received power for each user in its cell area and the interference from each other-cell. Compared to the direct method, the number of measurements can be largely reduced.
