Method for transmitting/receiving uplink signal between base station and terminal in wireless communication system, and device for supporting same

A method of transmitting a Physical Uplink Control Channel (PUCCH) signal by a User Equipment (UE) to a base station (BS) in a wireless communication system, the method comprising:

• determining a PUCCH configuration based on a combination of a higher layer signaling and downlink control information (DCI),
• wherein a plurality of candidates for a number of symbols for the PUCCH signal and a plurality of candidates for information on a symbol index for the PUCCH signal are configured via the higher layer signaling,
• wherein a certain number of symbols for the PUCCH signal among the plurality of candidates for the number of symbols for the PUCCH signal and a certain information on the symbol index for the PUCCH signal among the plurality of candidates for the information on the symbol index for the PUCCH signal are determined as the PUCCH configuration based on the DCI;
• and
• transmitting the PUCCH signal based on the PUCCH configuration.
