In this paper we apply constrained optimization techniques to optimally allocate bandwidth and transmit power to the users in a cellular network. We utilize partial frequency reuse with multiple users in the full and partial frequency regions as inter-cell interference mitigation technique. We show that the non-convex sum-rate maximization problem becomes convex under some simplifying assumptions. Moreover, an efficient and problem specific algorithm is developed to solve the problem for a fixed bandwidth allocation. Our results show that in the optimum, the full amount of power is assigned to the users. We further demonstrate that re-allocating the initially outer bandwidth to the inner bandwidth while keeping the power allocation unchanged, results in an increased sum-rate.
