ABSTRACT:
Disclosed herein are techniques for power management in wireless networks. Based upon receipt of an indication of the link margin of a receiving wireless device, a transmitting wireless device may adjust its transmit power commensurate with the link margin. The indication of the link margin may be transmitted from the receiving wireless device to the transmitting wireless device periodically. Alternatively, the receiving wireless station may provide the indication of the link margin in response to information received from the transmitting wireless device. In this instance, the indication of the link margin may be included in a piggyback acknowledgement (ACK) frame conventionally used to acknowledge receipt of the information transmitted by the transmitting wireless station.
