Multi-stage transmit power control scheme for access point
First Claim
1. A method of communication, comprising:
- maintaining information indicative of a desired coverage range for an access point;
receiving signals on at least one carrier frequency at the access point, wherein the signals are received from at least one other access point that transmits on at least one forward link on the at least one carrier frequency, and wherein the signals include a number of messages;
determining signal strength information associated with the signals;
setting transmit power limits for a transmit power algorithm based on the determined signal strength information and the maintained coverage range information; and
controlling transmit power of the access point according to the transmit power algorithm and the number of messages.

Abstract
Transmit power for an access point is controlled based on information received by the access point. For example, an access point may employ one or more algorithms that use messages received from nearby access terminals to maintain an acceptable tradeoff between providing an adequate coverage area for access point transmissions and mitigating interference that these transmissions cause at nearby access terminals. Here, the access point may employ a network listen-based algorithm upon initialization of the access terminal to provide preliminary transmit power control until sufficient information is collected for another transmit power control algorithm (e.g., an access terminal assisted algorithm). Also, the access terminal may employ an active access terminal protection scheme to mitigate interference the access point may otherwise cause to a nearby access terminal that is in active communication with another access point.
