Abstract
The Worldwide Interoperability for Microwave
Access (WiMAX) can provide wireless services at high rates even
in high mobility, but it can suffer from serious inter-cell
interference (ICI) near the cell boundary. To mitigate the ICI
problem in the downlink of mobile-WiMAX, we consider
combined use of interference avoidance and cancellation
techniques in addition to inter-sector coordination, maximizing
the user capacity in a seamless manner. To make the proposed
scheme realizable, we maximize the geometry capacity. Simulation
results show that the proposed scheme can improve the capacity of
users near the cell boundary over the conventional schemes and
provide flexibility in resource allocation.
