A SIGNAL ENCODING METHOD AND DEVICE AND A METHOD FOR ENCODING A JOINT FEEDBACK SIGNAL ARE PROVIDED. THE SIGNAL ENCODING METHOD INCLUDES THE FOLLOWING STEPS. WHEN TWO CARRIERS ARE CONFIGURED WITH MULTIPLE-INPUT AND MULTIPLE-OUTPUT (MIMO), HYBRID AUTOMATIC REPEAT REQUEST-ACKNOWLEDGEMENT (HARQ-ACK) SIGNALS OF THE TWO CARRIERS ARE COMBINED INTO A JOINT FEEDBACK SIGNAL.THE JOINT FEEDBACK SIGNAL IS MAPPED INTO A CODEWORD ACCORDING TO PREDETERMINED MAPPING RELATIONSHIP BETWEEN SIGNALS AND CODEWORDS.THEREFORE, THROUGH THE METHOD FOR COMBINING AND ENCODING FEEDBACK SIGNALS OF TWO CARRIERS FOR TRANSMISSION ON A CODE CHANNEL IN A DUAL CELL (DC)-MIMO MODE, BIT ERROR RATIO (BER) AND DETECTION ERROR COST ARE DECREASED, POWER OVERHEAD IS SAVED, AND A CUBIC METRIC (CM) VALUE OF THE SYSTEM IS NOT AFFECTED, THEREBY ENHANCING THE PERFORMANCE OF THE SYSTEM.
