Feedback information relating to a mobile communications system using carrier aggregation

摘要

The invention relates to a method for encoding a number of feedback information messages in a mobile radio communications system using carrier aggregation, the method comprising: encoding the number of feedback information messages by a set of codewords, where each feedback information message can be of at least a first kind or a second kind. The method is distinguished by that for at least one feedback information message there is at least one codeword corresponding to information of the first kind and at least one codeword corresponding to information of the second kind, wherein the modulation symbol of one of said at least one codeword corresponding to information of the first kind and the modulation symbol of one of said at least one codeword corresponding to information of the second kind have a maximum distance. The invention also relates to a mobile terminal and radio basestation for a communications system.

1. A method for communication of a number of feedback information messages in a mobile radio communications system using carrier aggregation, the method comprising:
receiving a number of feedback information messages encoded by a set of codewords, where each feedback information message is of at least a first kind or a second kind and each codeword comprises a channel selected from a number of A channels and a modulation symbol selected from a number of S modulation symbols, wherein for a feedback information message there is at least a first codeword corresponding to information of the first kind and at least a second codeword corresponding to information of the second kind, for said feedback information message a modulation symbol of said first codeword and a modulation symbol of said second codeword have a maximum distance, and wherein the codewords comprise the same channel and a different modulation symbol, and wherein for said feedback information message at least one of the S modulation symbols is unused for any codeword comprising said same channel.
