    摘要: The present invention relates to an uplink power control method and user equipment, which involve determining a power correction factor by considering the number of antenna ports. According to the present invention, even when a base station transmits the same power control information to the user equipment, the user equipment maps the power control information to another power correction factor and determines an uplink transmission power depending on an uplink transmission condition. Thus, uplink power control can be performed in a more efficient manner.
