Transmit power control of wireless communication devices
First Claim
1. A method for transmit power control of transmitting wireless device, the method comprises:
- transmitting, by the transmitting wireless device, a packet to a targeted wireless device via a wireless channel at a first power level;
determining, by the targeted wireless device, signal strength of the packet received via the wireless channel to produce a determined signal strength;
determining, by the targeted wireless device, adequacy of the first power level based on the determined signal strength;
when the first power level is not adequate, determining, by the targeted wireless device, a second power level for the transmitting wireless device based on the determination of the adequacy of the first power level; and
transmitting, by the targeted wireless device, a packet indicating the second power level to the transmitting wireless device via the wireless channel.

Abstract
A method and apparatus for controlling transmit power of a wireless communication device includes processing that begins when a transmitting wireless communication device transmits a packet to a targeted wireless device via a wireless channel of a communication system at a 1st power level. The processing continues by having the targeted wireless device determining signal strength of the packet received via the wireless channel. The processing then continues when the targeted and/or transmitting device determines the adequacy of the 1st power level based on the determined signal strength. If the 1st power level is adequate, the transmitting wireless device continues to transmit information at the 1st power level. If, however, the 1st power level is not adequate, the transmitting communication device adjusts its transmit power up or down to provide an adequate power level.
