Abstract:
The present specification relates to 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, the method comprising: a step for receiving a first PDCCH and a second PDCCH from a first transmission node and a second transmission node, respectively; a step for 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; a step for determining the type of HARQ-ACK codebook for the first PDSCH and the second PDSCH; and a step for transmitting HARQ feedback information for the determined HARQ-ACK codebook, wherein the first PDCCH and the second PDCCH include specific HARQ feedback timing information used for the CoMP, and 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.
