FIELD: radio engineering, communication.
SUBSTANCE: invention relates to mobile communication. The disclosure provides a method of controlling physical uplink control channel (PUCCH) power. User equipment (UE) determines a power control parameter nHARQ for a PUCCH format 3 transmission and performs power control on the PUCCH format 3 based on the nHARQ. The disclosure also provides a PUCCH power control apparatus. According to the disclosure, for a TDD system, the power control parameter nHARQ for the PUCCH format 3 transmission may be determined, which efficiently solves the problem regarding power control when feedback is performed in PUCCH format 3.
EFFECT: providing power control.
