  • Patent number: 7664047
    Abstract: An apparatus and corresponding method for deciding whether to perform link adaptation for communication transmitted from a first communication device to a second communication device, where the second communication device examines a signal received from the first communication device and provides a first indication of the quality of the signal. The method includes the steps of: recording at least one first indication of the quality of the signal as received by the second communication device; providing a second indication of the quality of the signal based on the at least one first indication of the quality of the signal; and deciding to perform link adaptation based on the second indication of the quality of the signal. The first indication of the quality of the signal is for example a signal to interference ratio (SIR) estimate. Often, the second indication of the quality of the signal is a changed SIR target value.
