We apply constrained optimization techniques to optimally allocate the bandwidth and power to the users in a cellular network. We investigate partial frequency reuse with multiple users in the full and partial frequency regions for inter-cell interference mitigation. We show that the non-convex sum-rate maximization problem becomes convex under certain simplifying assumptions. Moreover, an efﬁcient algorithm is developed to solve the problem for a ﬁxed bandwidth allocation. The optimal solution assigns all available power to the users. Finally, we prove that even without simpliﬁcations the non-convex problems of maximizing the minimum rate among users and minimizing the sum-power are transformable into convex forms.
