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.

Abstract: Provided are a method, a user equipment, a device and a recording medium in which: resource allocation information associated with a plurality of symbols is received; symbols which cannot be used for uplink transmission among the plurality of symbols are determined on the basis of the resource allocation information; and the uplink transmission is performed in at least one of the remaining symbols from the plurality of symbols excluding the symbols which cannot be used. The symbols which cannot be used comprise a symbol (DL symbol) in which a slot format is instructed as downlink (DL) and K non-DL symbols immediately after the DL symbol among the plurality of symbols. Each of the K non-DL symbols is a symbol in which a slot format is not instructed as DL, and K is an integer greater than 0.
