1. A method of transmitting an Acknowledgement/Negative acknowledgement (A/N) information by a user equipment (UE) in a wireless communication system, the method comprising:
receiving a plurality of Downlink Control Information (DCI) for scheduling a plurality of Physical Downlink Shared Channels (PDSCHs);
obtaining, from each of the plurality of DCI, (i) information related to a PDSCH group of a PDSCH corresponding each of the plurality of DCI and (ii) a Downlink Assignment Index (DAI) for the PDSCH;
receiving the plurality of PDSCHs based on the plurality of DCI;
determining an A/N information corresponding only to at least one PDSCH, among the plurality of PDSCHs, based on at least one DCI for scheduling the at least one PDSCH among the plurality of DCI,
wherein the at least one PDSCH is included in a same PDSCH group with a PDSCH group related to a last received DCI among the plurality of DCI, and
wherein the last received DCI is included in the at least one DCI, and
transmitting the A/N information.
