1. A method of transmitting hybrid automatic repeat request (HARD) acknowledgement (ACK) (HARQ-ACK) information by a user equipment in a wireless communication system, the method comprising:
performing physical downlink shared channel (PDSCH) reception in a plurality of cells including a primary cell and including a secondary cell configured for physical uplink control channel (PUCCH) cell switching;
determining a HARQ-ACK feedback timing value K for the PDSCH reception among a set of HARQ-ACK feedback timing values configured for the primary cell;
determining a slot n+K on the primary cell based on a last slot n overlapping with the PDSCH reception among slots of the primary cell and on the HARQ-ACK feedback timing value K; and
transmitting the HARQ-ACK information for the PDSCH reception in a slot m on the secondary cell, based on using the secondary cell for transmission of the HARQ-ACK information for the PDSCH reception based on the PUCCH cell switching,
wherein the slot m is a first slot among slots of the secondary cell overlapping with the slot n+K.
