Spatial Domain Resource Sharing for Overlapping Cells in Indoor Environment

الملخص EN

As microcell wireless systems become more widespread, intercell interference among the access points will increase due to the limited frequency resource.

In the overlapping cell scenario, radio resources should be shared by multiple cells.

Although time and frequency resource sharing has been described in many papers, there is no detailed report on dynamic spatial resource sharing among multiple cells for microcell wireless systems.

Thus, we present the effectiveness of spatial resource sharing among two access points.

We introduce two scenarios based on the zero forcing method; one is the primary-secondary AP scenario and the other is the cooperative AP scenario.

To evaluate the transmission performance of spatial resource sharing, channel matrices are measured in an indoor environment.

The simulation results using the measured channel matrices show the potential of spatial resource sharing.
