(English Abstract) |
The Mobile-Worldwide Interoperability for Microwave Access (m-WiMAX) can provide wireless services at high rates even in high mobility. However, the performance of m-WiMAX can seriously be degraded near the cell boundary due to inter-cell interference (ICI). To mitigate the ICI problem in the downlink of mWiMAX, we consider combined use of ICI mitigation techniques with macro beamforming to maximize the user capacity in response to the change of interference environment. The proposed scheme optimally determines the configuration of ICI mitigation techniques using the geometrical information (e.g., the longterm received signal strength of neighboring cells). Simulation results show that the proposed scheme can accurately estimate the user capacity and thus improve the capacity of users near the cell boundary.
