Abstract
A system for transmitting data is provided. The system includes a first station having a processor to format source data into data frames and idle frames, and a module to transmit the data and idle frames. A second station is in communication with the first station and has a module to receive the data frames and idle frames and a processor configured to detect an absence of an expected data frame, transmit a plurality of repeat negative acknowledgements if the absent expected data frame is not received, transmit a negative acknowledgement corresponding to the absent expected data frame, determine whether a rate of idle frames exceeds a predetermined threshold and reduce transmission of repeat negative acknowledgements when the rate of idle frames does not exceed the predetermined threshold. The first station may be a base station and the second station may be a mobile station.
