SYSTEM AND METHOD FOR TRANSMITTING AND RECEIVING ACKNOWLEDGEMENT INFORMATION

摘要

A system and method for transmitting and receiving acknowledgement information are provided.A method for communication device operations includes: determining a hybrid automatic repeat request (HARQ) response for each component carrier (CC) in a set of configured CCs,thereby producing a set of HARQ responses,generating an information vector from the set of HARQ responses,encoding the information vector,and transmitting the encoded information vector.A sub-vector of one or more bits selected from the information vector is assigned a fixed vector value independent of HARQ responses for CCs not in a set of CCs when the set of CCs is not empty,wherein the set of CCs comprises at least one CC whose HARQ response is equal to Discontinuous Transmission (DTX).
