OPPORTUNISTIC RELAY SCHEDULING IN WIRELESS COMMUNICATIONS
First Claim
1. A method, comprising:
- maintaining a backhaul link with one or more access points;
determining one or more backhaul link resources over which information is received from the one or more access points over the backhaul link; and
selecting one or more access link resources, based on the one or more backhaul link resources, for communicating with one or more mobile devices over an access link.

Abstract
Systems and methodologies are described that facilitate providing opportunistic relay node communication based on scheduling of other communications in a wireless network. In particular, a relay node can maintain a backhaul link with an access point and an access link with a mobile device to facilitate communicating information therebetween. Time slots during which the backhaul link is active can be determined and avoided during scheduling access link communications with the mobile device. Furthermore, resource assignments from the access point to the mobile device can be monitored and decoded such that time slots associated therewith can also be determined and avoided. Thus, the relay node can communicate with mobile devices in time slots where the backhaul link is inactive and/or the mobile devices are not occupied communicating directly with the access point.
