Patent ID: 7603136

Claim:
A method to control power transmitted from a node in a wireless network, the method comprising: receiving one or more signals at the node from one or more other nodes of the wireless network; determining a signal-to-interference-plus noise ratio for each signal received from each of the one or more other nodes; transmitting the determined signal-to-interference-plus noise ratio value for each signal received from the one or more other nodes to the respective one or more other nodes; receiving a signal-to-interference-plus noise ratio value from each of the other nodes in the wireless network, wherein the receive signal-to-interference-plus noise ratio value was determined by each of the other nodes; determining a minimum signal-to-interference-plus noise ratio of the node; estimating a rate-of-change of the channel gain; and adjusting signals transmitted from the node to the other nodes based on the determined minimum signal-to-interference-plus noise ratio of the node, the signal-to-interference-plus noise ratio value received from each of the other nodes, and the estimated rate-of-change of the channel gain, wherein a total power level transmitted from the node is maintained near a minimum power level.
