Method for adusting power at a node
First Claim
1. A method for distributed power control in a network, the method comprising:
- determining a transmit power for a plurality of transmitting nodes such that signals sent from each of the transmitting nodes are received at a receiving node at a signal to interference plus noise ratio (SINR) set point;
determining an average rate of information transmitted per transmitting node of the plurality of transmitting nodes;
increasing the SINR at the receiving node of one or more transmitting nodes of the plurality of transmitting nodes; and
decreasing the SINR at the receiving node of one or more other transmitting nodes of the plurality of transmitting nodes;
wherein a total increase in SINR by the one or more transmitting nodes is substantially equal to total decrease in SINR by the one or more other transmitting nodes.

Abstract
In one embodiment, a method for distributed power control in a network is provided. The method determines a transmit power for a plurality of transmitting nodes such that signals sent from each of the transmitting nodes are received at a receiving node at a signal to interference plus noise ratio (SINR) set point. Additionally, the method increases the SINR at the receiving node of one or more transmitting nodes of the plurality of transmitting nodes, and decreases the SINR at the receiving node of one or more other transmitting nodes of the plurality of transmitting nodes; wherein a total increase in SINR by the one or more transmitting nodes is substantially equal to total decrease in SINR by the one or more other transmitting nodes.

8. A method for distributed power control in a network, the method comprising:
-
providing an average rate of information transmitted per transmitting node of a plurality of nodes; comparing a rate of information to be transmitted from a first transmitting node of the plurality of nodes to the average rate of information transmitted per transmitting node of the plurality of nodes; and adjusting a signal to interference plus noise ratio (SINR) of the first transmitting node based on the amount of information to be transmitted by the first transmitting node; wherein the SINR is adjusted in proportion to a difference between the average rate of information transmitted per transmitting node and the rate of information to be transmitted from the first transmitting node. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A network comprising:
-
a plurality of nodes in communication with each other, a receiving node of the plurality of nodes configured to receive a signal transmitted by at least one of a plurality of transmitting nodes of the plurality of nodes, each transmitting node configured to determine a transmit power such that signals sent from each of the transmitting nodes are received at the receiving node at a SINR set point; at least one transmitting node configured to increase its SINR; and at least one other transmitting node configured to decrease its SINR, wherein a total increase in SINR by the at least one transmitting node is substantially equal to a total decrease in SINR by the at least one other transmitting node; wherein each of the plurality of transmitting nodes is configured to determine an amount of information to be transmitted to the receiving node, wherein increasing the SINR of the at least one transmitting node is based on an amount of information to be transmitted, and wherein decreasing the SINR of the at least one other transmitting node is based on an amount of information to be transmitted; wherein a SINR of a signal received by the receiving node is proportional to the amount of information to be transmitted; wherein each transmitting node determines an average rate of information transmitted per transmitting node of the plurality of nodes. - View Dependent Claims (16)
