Investigation on Spatial Reuse by Using Virtual Relay in 60GHz Dense Environment

The directivity characteristic in 60GHz communication brings great potential to do spatial reuse in a dense environment, which usually requires the ability of network to support concurrent connections within the same space. This paper proposed a new approach to achieve interference mitigation and spatial reuse, which use the physical reflector as the virtual relay to forward signal to the target node. The exhaust method is used to perform path selection to maximize the overall channel capacity. Numerical simulations demonstrate that the overall channel capacity can be improved and the outage ratio of link can be decreased.
