Abstract
A communications link is adapted based on a quality estimate for a signal transmitted via the communications link. The method comprises receiving and demodulating the transmitted signal, assessing the demodulated signal to derive a first estimate for the signal quality that is to be used in a link adaptation scheme, and further processing and decoding the demodulated signal. Based on at least one of the further processed, non-decoded signal and information obtained prior to conclusion of decoding, a first control signal indicative of the signal quality is generated and utilized to control the link adaptation scheme.
