1. A method comprising:
- generating a transmission packet parameter associated with packets transmitted by a device at a first data rate that is selected from a plurality of data rates;
generating a reception packet parameter associated with packets received by the device;
generating confidence values for the plurality of data rates using information comprising the transmission packet parameter and the reception packet parameter;
determining, from the plurality of data rates, a second data rate based on the transmission packet parameter and the reception packet parameter, wherein determining the second data rate is performed based on at least a portion of the confidence values; and
transmitting future packets at the second data rate.

Abstract
Systems and techniques for rate adaptation in wireless communication systems are described. A described technique includes generating a transmission packet parameter associated with packets transmitted by a device at a first data rate; generating a reception packet parameter associated with packets received by the device; determining a second data rate based on the transmission packet parameter and the reception packet parameter; and transmitting future packets at the second data rate.

7. A device comprising:
-
a first section configured to transmit packets at a first data rate and to generate a transmission packet parameter associated with the transmitted packets; a second section configured to receive packets and to generate a reception packet parameter associated with the received packets; and a rate selector to determine a second data rate from a plurality of data rates including the first data rate based on the transmission packet parameter and the reception packet parameter, the second data rate to be used by the first section for transmitting future packets, wherein the rate selector is configured to generate a confidence value for each of the plurality of data rates using information comprising the transmission packet parameter and the reception packet parameter. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17)
