Abstract: A method for a terminal to transmit hybrid automatic repeat and request (HARQ) feedback information in a wireless communication system supporting coordinated multiple point (CoMP) transmission includes: receiving a first PDCCH and a second PDCCH from a first transmission node and a second transmission node, respectively; receiving, from the first transmission node and the second transmission node, a first PDSCH and a second PDSCH scheduled by the first PDCCH and the second PDCCH, respectively; determining HARQ-ACK codebook for the first PDSCH and the second PDSCH; and transmitting HARQ feedback information for the determined HARQ-ACK codebook. The first and second PDCCHs include specific HARQ feedback timing information used for the CoMP. When a reception occasion for the first PDSCH and a reception occasion for the second PDSCH overlap, the HARQ feedback information is transmitted on a slot corresponding to the value indicated by the specific HARQ feedback timing information.
