Direct link relay in a wireless network
First Claim
1. In a wireless network comprising an access point communicating with at least a first wireless device and a second wireless device, a method comprising:
- receiving, at the first wireless device, uplink information from the second wireless device via a direct wireless link between the first and second wireless device, wherein a destination of the uplink information includes a networked device communicable with the access point; and
relaying at least a portion of the uplink information from the first wireless device to the access point for transmission to the networked device.

Abstract
Disclosed herein are exemplary techniques for power conservation in a wireless network. A wireless device identifies another wireless device suitable to act as a relay node. Uplink information is transmitted to the other wireless device, which is in turn relayed to an access point for transmission to its destination. Downlink information may be transmitted directly from the access point to the wireless device. The use of a relay node may reduce transmit power consumption as the relay node may be closer to, or support a higher transmit rate, than the access point with which the wireless device is associated.
