METHOD FOR DETERMINING WHETHER TO PERFORM LINK ADAPTATION IN WCDMA COMMUNICATIONS

摘要

An apparatus and method for deciding whether to perform link adaptation forcommunication transmitted from a first communication device (12) to a secondcommunication device (11), where the second communication device (11) examinesa signal received from the first communication device (12) and provides afirst indication of the quality of the signal. The method includes steps of:recording at least a first indication of the quality of the signal as receivedby the second communication device (11); providing a second indication of thequality of the signal based on the at least one first indication of thequality of the signal; and deciding whether to perform link adaptation basedon the second indication of the quality of the signal. The first indication ofthe signal quality is for example a signal to interference ratio (SIR)estimate. Often, the second indication of the signal quality is a changed SIRtarget value.
