1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station, downlink control information (DCI) on a physical downlink control channel (PDCCH), the DCI scheduling downlink data for the UE;
receiving the downlink data on a physical downlink shared channel (PDSCH) based on the received DCI; and
transmitting, to the base station, hybrid automatic repeat request acknowledgement (HARQ-ACK) information in response to the reception of the downlink data,
wherein the transmission of the HARQ-ACK information is associated with a first PDSCH processing capability or a second PDSCH processing capability,
wherein the first PDSCH processing capability has a PDSCH processing time slower than a PDSCH processing time of the second PDSCH processing capability, and
wherein the first PDSCH processing capability is applied to the PDSCH scheduled by the PDCCH with the DCI in case that the downlink data is multicast data.
