Joint radio resource allocation and scheduling in a backhaul constrained multicell OFDMA network

This paper addresses a joint radio resource allocation (RRA) and scheduling problem in a multi-cell OFDMA network in which the backhaul capacity is constrained. The proposed scheme is pursuing both the network utility and fairness among all users in two different levels, the intracell level and the intercell level. Analysis and simulation results suggest the proposed scheme brings better performance for the cell edge users, and manages to build cooperation links between adjacent cells without extra signal overhead for the network.
