Opportunistic relay scheduling in wireless communications

摘要

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.

主权项

1. A method, comprising:
maintaining, by a relay node, a backhaul link with a base station, the relay node being a relay between the base station and a mobile device, and the base station providing network access to the mobile device; determining, by the relay node, at least one backhaul link resource over which information is received from the base station over the backhaul link; determining, by the relay node, at least one uplink resource over which information is transmitted from the mobile device to the base station; selecting, by the relay node, at least one access link resource for communicating with the mobile device over an access link, the at least one access link resource being different from the at least one backhaul link resource and the at least one uplink resource; and transmitting a resource assignment message to the mobile device based at least in part on the selected at least one access link resource.
