Terminal and communication method using semi-static physical uplink control channel (pucch) resource configuration

An integrated circuit for controlling a terminal, the integrated circuit comprising:

• reception circuitry, which, in operation, receives, by using a User Equipment (UE)-specific higher-layer signaling, a semi-static Physical Uplink Control Channel (PUCCH) resource configuration including a PUCCH resource set, and receives, by using a Downlink Control Information (DCI), an identification of a PUCCH resource to be used for transmitting ACK/NACK to a Physical Downlink Shared Channel (PDSCH), among a plurality of PUCCH resources included in the PUCCH resource set, wherein the PUCCH resource is configured with one or more parameters including information on a number of PUCCH repetitions, wherein the number is 1 (absence of PUCCH repetition) or 2 or more;
• control circuitry, which, in operation, configures a plurality of first transmission occasions for a unit time duration corresponding to a scheduling unit according to the semi-static PUCCH resource configuration;
• and
• transmission circuitry, which, in operation, performs a repeated transmission of uplink control information in the plurality of first transmission occasions according to the number of PUCCH repetitions indicated by the DCI,
• wherein a PUCCH format usable in the repeated transmission of the uplink control information has a defined symbol length equal to or smaller than a threshold value.
