Spatial reuse techniques with wireless network relays
First Claim
1. An apparatus, comprisinga first relay station to relay wireless communications between a base station and a first subscriber station, the first relay station having a computing platform, a modulator, and a demodulator, the first relay station to:
- communicate with the base station using a first time/frequency resource;
andcommunicate with the first subscriber station using a second time/frequency resource;
wherein a second relay station is scheduled to communicate with a second subscriber station using the first time/frequency resource and the second relay station is scheduled to communicate with the base station using the second time/frequency resource;
wherein the first and second time/frequency resources are both periods of time or are both one or more frequencies.

Abstract
In various embodiments of the invention, a relay station in a wireless communications network may communicate with one or more subscriber stations at the same time and/or on the same frequency that the associated base station is communicating with another relay station in the same network. This contrasts with the conventional technique of devoting one time period or frequency exclusively to communications between the base station and the relay stations, and devoting another time period or frequency exclusively to communications between the relay stations and the subscriber stations.
