Method, device, and system for transmitting or receiving uplink control channel in wireless communication system

A method of wireless communication by a User Equipment (UE) operates in a wireless communication system, the wireless communication method comprising:

• transmitting uplink control information (UCI) which includes hybrid automatic repeat request acknowledgment (HARQ-ACK) information representing a response to a downlink channel having been received from a base station, a scheduling request (SR) representing whether to request for uplink resource allocation, and a beam recovery request (BR) representing whether to request for recovery for a beam failure,
• when a number of bits of the UCI does not exceed 2, transmitting the UCI using a physical uplink control channel (PUCCH) format 0 generated by cyclic-shifting a base sequence based on a second CS value, wherein a first CS value is determined based on the HARQ-ACK information, wherein a CS offset is determined based on request information representing a request to be transmitted from the UE to the base station, wherein the second CS value representing a degree of cyclic-shifting the base sequence to be used in a PUCCH based on the first CS value and the CS offset, wherein a transmission resource of the PUCCH format 0 is one resource block representing 12 subcarriers in a frequency domain, and
• when the number of bits of the UCI exceeds 2, transmitting the UCI using a PUCCH format 2,
• wherein when the number of bits of the UCI exceeds 2, the UCI includes one or more bits representing the HARQ-ACK information, one or more bits representing the SR, and one or more bits representing BR.
