Method and apparatus for transmit power control in wireless networks

摘要

A method and apparatus are described including receiving, by a transmitter, a report from an associated client, setting and using a downlink transmit power level responsive to the report for data transmissions to the associated client, determining a downlink data loss rate and adjusting the downlink transmit power level responsive to the downlink data loss rate, wherein said report includes received signal strength, client transmit power level and one of link margin and receiver sensitivity. Also described are a method and apparatus including receiving, by a receiver, a request for a report, transmitting the requested report, receiving an instruction to use an uplink transmit power level, setting and using the uplink transmit power level, determining an uplink data loss rate and adjusting the uplink transmit power level responsive to the uplink data loss rate, wherein said report includes said received signal strength, client transmit power level and one of said link margin and said receiver sensitivity.

1. A method, said method comprising:
setting an adjustment timer; receiving, by a transmitter, a report from at least one associated client, wherein said report includes data indicating received signal strength, client transmit power level, and at least one of link margin and receiver sensitivity; setting a downlink transmit power level for each of the at least one associated client responsive to said report; using said downlink transmit power level for data transmissions to each of the at least one associated client; upon expiration of said adjustment timer, determining a downlink data loss rate using a number of retransmission requests in a time interval set by said adjustment timer; if said downlink data loss rate is greater than a threshold, adjusting said downlink transmit power level responsive to said downlink data loss rate for each of the at least one associated client; and using a data loss measurement window to maintain status of most recent data transmissions for each of the at least one associated client.
