Power regulation using multi-loop control

5 The method of claim 4 wherein said power adjustment information addressed to said second node is identified by an MCNS primary subscriber ID of said second node.

In a communication system, a method for operating a first node comprising:

• transmitting a series of transmissions from said first node to a second node;
• and
• regulating transmitted power level of said series of transmissions in accordance with power measurements made on said series of transmissions wherein the influence of older ones of said power measurements on said transmitted power level varies with elapsed time since a most recent one of said power measurements.

In a communication system, apparatus for operating a first node comprising:

• a receiver system that receives a series of transmissions from a second node and measures received power levels of said series of transmissions;
• and
• a control processor that sends power adjustment information to said second node to regulate output power level of said second node, wherein influence of older ones of said received power levels on said output power level varies with elapsed time since a last one of said series of transmissions.

The apparatus of 19 wherein said communication system comprises a point to multipoint communication system, said first node comprises a central access point and said second node comprises a subscriber unit.

In a communication system, apparatus for operating a first node comprising:

• a transmitter system that transmits a series of transmissions from said first node to a second node;
• and
• a control processor that regulates transmitted power level of said series of transmissions in accordance with power measurements made on said series of transmissions wherein the influence of older ones of said power measurements on said transmitted power level varies with elapsed time since a most recent one of said power measurements.
