This paper discusses solutions that provide forward link power allocation based on 3GPP (FDD) standardization reports and that meet the Eb/No required for forward link channels. In addition, we determine the forward link user capacity under a mixed service environment. Cell coverage is derived using the solutions from the forward link user capacity problem and an urban propagation model. These results are achieved with the introduction of various factors, such as the number of users, service types, macro/microcell environments, and others. Our study shows that for IMT-2000 systems offering a mixed service environment, forward link power should be carefully allocated depending on the ratio of users occupied by each service type if one is to achieve optimal cell planning.
