Patent ID: 7363004

Claim:
A method for generating feedback information for controlling transmission from a transmitting end using a set of feedback symbols, said feedback information comprising a set of feedback words, the method comprising: determining at least one feedback symbol based on at least one signal received from a transmitting end; and determining a feedback word to be transmitted to the transmitting end, said feedback word relating to a determined feedback symbol, using a mapping between a set of feedback symbols and a set of feedback words that takes into account an effect of at least one transmission error in transmitting the feedback word to the transmitting end, said mapping between said set of feedback symbols and said set of feedback words being different from a mapping relating to Gray encoding, wherein determining the feedback word comprises determining a binary feedback word comprised in the feedback word by the mapping between said set of feedback symbols and said feedback words, the mapping minimizing an average square Euclidean distance of feedback symbol errors ensuing from a given number of feedback bit errors.
