Abstract (en)
[origin: WO2005034385A1] A method is discussed for generating feedback information for controlling transmission from a transmitting end using a set of feedback symbols. The feedback information comprises a set of feedback words. At least one feedback symbol is determined based on at least one signal received from the transmitting end. A feedback word to be transmitted to the transmitting end is determined, the feedback word relating to the determined feedback symbol, by a mapping between said set of feedback symbols and said set of feedback words. This mapping takes into account the effect of at least one possible transmission error in transmitting the feedback word to the transmitting end. Furthermore, the mapping is different from a mapping relating to Gray encoding.
