Abstract: A method and apparatus for transmitting and receiving uplink control information in a wireless communication system are disclosed. A method performed by a user equipment in a wireless communication system according to an embodiment of the present disclosure may comprise the steps of: receiving configuration information on PUCCH cell switching; and receiving a PDSCH indicated by downlink control information. Here, HARQ-ACK transmission for the PDSCH may be configured to one of a first HARQ-ACK mode based on a ACK value and a NACK value and a second HARQ-ACK mode based on a NACK value. Based on the HARQ-ACK transmission being allocated to a time interval for PUCCH cell switching, the HARQ-ACK transmission is performed on a switched PUCCH cell or is dropped, according to a HARQ-ACK mode configured to the HARQ-ACK transmission.

Abstract: According to an embodiment, a user equipment (UE) receives downlink control information (DCI) through a physical downlink control channel (PDCCH), determines a downlink resource allocated to the UE based on a frequency domain resource allocation (FDRA) field included in the DCI, and receives a physical downlink shared channel (PDSCH) in the downlink resource, and in this case, based on that a first bandwidth of the UE supported for the PDCCH is different from a second bandwidth of the UE supported for the PDSCH, the UE determines the downlink resource allocated through the FDRA field based on the second bandwidth other than the first bandwidth.

Abstract: A method and apparatus for transmitting and receiving uplink control information in a wireless communication system are disclosed. A method performed by a user equipment in a wireless communication system according to an embodiment of the present disclosure may comprise the steps of: receiving configuration information on one or more SPS configurations; and performing SPS PDSCH reception based on a specific SPS configuration among the one or more SPS configurations. Here, each of the one or more SPS configurations may be associated with one of a first HARQ-ACK mode based on a ACK value and a NACK value, and a second HARQ-ACK mode based on a NACK value. Based on the PUCCH resource related to HARQ-ACK transmission for the SPS PDSCH reception being invalid, the HARQ-ACK transmission may be deferred or dropped according to a HARQ-ACK mode associated with the specific SPS configuration.
