Abstract:
1. A method performed by at least one device of a communication system, the method comprising: determining a signal quality value from received packets transmitted at a first data transmission rate; determining a packet loss indicator value from transmitted packets transmitted at a second different data transmission rate; selecting a third different data transmission rate in response to the signal quality value determined from the received packets transmitted at the first data transmission rate and the packet loss indicator value determined from the transmitted packets transmitted at the second different data transmission rate, wherein the selecting includes selecting the third different data transmission rate from a plurality of available data transmission rates, and each of the plurality of available data transmission rates is different from the first data transmission rate and the second different data transmission rate; transmitting packets at the third different data transmission rate; and generating a confidence value for each of a plurality of available data transmission rates using the signal quality value and the packet loss indicator value.
