    Abstract

    Aiming at the heterogeneity of transmission performance in heterogeneous networks (HetNets) consisting of multiple cells, an optimal cell selection and power allocation scheme is proposed to improve QoS and QoE of users. For one UE case, the proposed scheme selects the optimal cell corresponding to the maximum energy efficiency of the UE. In the case of multiple UEs, the QoS and power constrained energy optimization problem is equivalently transformed into two sub-problems, which are power allocation of each UE-cell pair and cell selection of UEs. The two sub-problems are solved respectively by applying Lagrange dual method and Kuhn-Munkres (K-M) algorithm. Numerical results demonstrate the efficiency of the proposed algorithm.
