1. A method performed by a terminal in a communication system, the method comprising:
receiving, from a base station on a physical downlink control channel (PDCCH), wherein physical resource block information for a physical uplink control channel (PUCCH) and a transmission power control command for the PUCCH are included in the PDCCH;
identifying a transmission power for the PUCCH based on the transmission power control command for the PUCCH, path loss information, and a PUCCH transmission power adjustment component, wherein the PUCCH transmission power adjustment component is obtained by a number of PUCCH symbols and the PUCCH transmission power adjustment component is inversely related to the number of the PUCCH symbols; and
transmitting, to the base station, the PUCCH on a physical resource block for the PUCCH in the PUCCH symbols, based on the transmission power.
