## Abstract

Disclosed is a method performed by a terminal in a wireless communication system including receiving, from a base station, physical uplink control channel (PUCCH) configuration information including first information on a number of plural slots for repetition of a PUCCH transmission, second information on a number of consecutive symbols for the PUCCH transmission, and third information on at least one physical resource block (PRB) for the PUCCH transmission, receiving, from the base station, downlink control information (DCI), determining the plural slots for the repetition of the PUCCH transmission starting from a first slot indicated to the terminal by the DCI, based on the PUCCH configuration information, and transmitting, to the base station, a PUCCH at the determined plural slots based on the at least one PRB according to the third information, wherein each of the determined plural slots has the number of consecutive symbols for the PUCCH transmission according to the second information and the terminal does not perform the PUCCH transmission at a slot having a number of symbols available for PUCCH transmission smaller than the number of consecutive symbols for the PUCCH transmission according to the second information.

## Claims

### Claim 1

A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, physical uplink control channel (PUCCH) configuration information including information on a number of plural slots for repetition of a PUCCH transmission, information on an index of a first physical resource block (PRB), and information on an index of a second PRB;
receiving, from the base station, a downlink control channel;
determining the plural slots for the repetition of the PUCCH transmission starting from a first slot indicated by the downlink control channel, based on slot format information per slot; and
transmitting, to the base station, a PUCCH over the determined plural slots,
wherein the PUCCH transmission according to the first PRB and the second PRB is identical at each of the determined plural slots, and
wherein the PUCCH transmission in each of the determined plural slots has a same number of consecutive symbols for the PUCCH identified based on the downlink control channel.

### Claim 2 (depends on 1)

The method of claim 1,
wherein the slot format information is configured by a semi-static signalling.

### Claim 3 (depends on 1)

The method of claim 1,
wherein the downlink control channel is for scheduling a physical downlink shared channel (PDSCH), and
wherein hybrid automatic repeat request-acknowledgement information for the PDSCH is transmitted on the PUCCH.

### Claim 4

A method performed by a base station in a wireless communication system, the method comprising:
transmitting, to a terminal, physical uplink control channel (PUCCH) configuration information including information on a number of plural slots for repetition of a PUCCH transmission, information on an index of a first physical resource block (PRB), and information on an index of a second PRB;
transmitting, to the terminal, a downlink control channel; and
receiving, from the terminal, a PUCCH over the plural slots,
wherein the plural slots are determined based on slot format information per slot, starting from a first slot indicated by the downlink control channel,
wherein the PUCCH transmission according to the first PRB and the second PRB is identical at each of the determined plural slots, and
wherein the PUCCH transmission in each of the determined plural slots has a same number of consecutive symbols for the PUCCH identified based on the downlink control channel.

### Claim 5 (depends on 4)
