Abstract: A UE may perform PDSCH reception in a plurality of cells including a primary cell and including a secondary cell configured for PUCCH cell switching, determine a slot n+K on the primary cell, based on a HARQ-ACK feedback timing value K for the PDSCH reception determined among a set of HARQ-ACK feedback timing values configured for the primary cell and on a last slot n overlapping with the PDSCH reception among slots of the primary cell, and transmit 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. The slot m may be a slot including start of the slot n+K among slots of the secondary cell overlapping with the slot n+K.
