Abstract

In a multi-level power transmission scheme, an access point transmits at one power level, while repeatedly transmitting at a burst power level for short periods of time. For example, a femto cell may transmit a beacon with periodic high power bursts of short duration, while the femto cell transmit power also undergoes high power bursts aligned with the beacon bursts. In a network listen-based power control scheme, an access point listens for one or more parameters sent over-the-air by the network and then defines transmit power based on the received parameter(s). In some aspects, beacon transmit power may be set based on a defined outage radius parameter and the total received signal power on a channel. In some aspects, access point transmit power may be set based on a defined coverage parameter and the received energy associated with signals from access points of a certain type.

First claim

What is claimed is:

1. A method of communication, comprising:
receiving radiofrequency signals on a radio channel at an access point;
determining total received signal power associated with the radio channel based on the received radiofrequency signals; and
determining beacon transmit power for the access point based on the total received signal power and a defined path loss target that corresponds to an outage region within which transmission of a beacon by the access point c…
