Uplink transmission power control method and device in wireless cellular communication system

A method performed by a base station in a communication system, the method comprising:

• transmitting, to a terminal via higher layer signaling, a configuration including information associated with a number of physical uplink control channel (PUCCH) symbols for a PUCCH format;
• transmitting, to the terminal on a physical downlink control channel (PDCCH), a power control command for a PUCCH;
• and
• receiving, from the terminal, the PUCCH transmitted based on a transmission power,
• wherein the transmission power is based on the power control command for the PUCCH and a PUCCH transmission power adjustment component, and
• wherein the PUCCH transmission power adjustment component is obtained by the number of the PUCCH symbols for the PUCCH format and the PUCCH transmission power adjustment component is increased as the number of the PUCCH symbols for the PUCCH format is decreased.

A terminal in a communication system, the terminal comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• receive, from a base station via higher layer signaling, a configuration including information associated with a number of physical uplink control channel (PUCCH) symbols for a PUCCH format,
• receive, from the base station on a physical downlink control channel (PDCCH), a power control command for a PUCCH,
• identify a transmission power based on the power control command for the PUCCH and a PUCCH transmission power adjustment component, wherein the PUCCH transmission power adjustment component is obtained by the number of the PUCCH symbols for the PUCCH format and the PUCCH transmission power adjustment component is increased as the number of the PUCCH symbols for the PUCCH format is decreased, and
• transmit, to the base station, the PUCCH based on the transmission power.
