WLC25-3: Resource Management Policies for Fixed Relays in Cellular Networks

Mobile stations in the cell boundary have poor spectral efficiency due to the path loss and the interference from adjacent cells. Therefore it becomes an important issue to satisfy QoS requirements of each MS at the cell boundary. The deployment of fixed relay stations has been actively considered to solve this spectral efficiency problem at the cell boundary. In this paper, we consider some radio resource management policies that are path selection rule, frequency reuse pattern matching, and frame transmission pattern matching among cells. We evaluate performances of using relays under these policies by varying parameter values such as the relay station´s position and frequency reuse factor. Through Monte Carlo simulations and mathematical analysis, we also suggest some optimal values of parameters and policies.
