A method and an apparatus for transmitting a hybrid automatic repeat request (HARQ) response of a physical downlink shared channel (PDSCH) may comprise receiving a first semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) from a base station, generating first hybrid automatic repeat request-acknowledgement (HARQ-ACK) information of the first SPS PDSCH, determining a second resource after a first resource when transmission of the first HARQ-ACK information is not performed in the first resource, and transmitting a HARQ-ACK codebook including the first HARQ-ACK information using the second resource to the base station.
