Simplified Explanation

The present disclosure describes a method and device for a wireless communication system. The method involves receiving configuration information about multiple cells, including a first cell with a higher priority and a second cell with a lower priority. The method also includes receiving a request for HARQ-ACK feedback via DCI (Downlink Control Information) and transmitting an HARQ-ACK codebook for the cells based on the feedback request. The HARQ-ACK information in the codebook is arranged in descending order of the first cell index and HARQ process index. The HARQ-ACK information for the second cell is excluded from the codebook since the first priority is indicated by the DCI.


Original Abstract Submitted

The present disclosure relates to a wireless communication system, and specifically to a method and a device therefor, the method comprising: a step for receiving configuration information about a plurality of cells comprising (i) a first cell having a first HARQ process index and operable with a first priority, and (ii) a second cell having only a second HARQ process index and operating only with a second priority lower than the first priority; a step for receiving an HARQ-ACK feedback request via DCI; and a step for transmitting an HARQ-ACK codebook for the plurality of cells on the basis of the HARQ-ACK feedback request, wherein HARQ-ACK information in the HARQ-ACK codebook is in descending order of first cell index and then HARQ process index, and the HARQ-ACK information about the second cell is excluded from the HARQ-ACK codebook on the basis that the first priority is indicated by the DCI.
