Method for terminal for carrying out uplink communication in wireless communication system, and terminal using method

A user equipment (UE) configured to perform physical uplink control channel (PUCCH) transmission to a base station (BS) in a wireless communication system, the UE comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations comprising:
• receiving, from the BS, a plurality of settings for the PUCCH transmission, wherein each of the plurality of settings includes information identifying a respective one of a plurality of reference signals;
• receiving, from the BS, a signal informing of a setting among the plurality of settings for the PUCCH transmission;
• determining a transmission power for the PUCCH transmission based on at least one power control parameter included in the setting;
• and
• performing the PUCCH transmission using the transmission power.

A method of receiving a physical uplink control channel (PUCCH) by a base station (BS) in a wireless communication system, the method comprising:

• transmitting, to a user equipment (UE), a plurality of settings for a PUCCH transmission by the UE to the BS, wherein each of the plurality of settings includes information identifying a respective one of a plurality of eference signals;
• transmitting, to the UE, a signal informing of a setting among the plurality of settings for the PUCCH transmission;
• and
• receiving, from the UE, the PUCCH of which transmission power is determined based on at least one power control parameter included in the setting.
