Abstract: The present invention relates to a method of transmitting uplink control information (UCI), which is transmitted by a user equipment in a wireless communication system. In particular, the method includes the steps of receiving first offset information associated with uplink control information (UCI) transmission in uplink subframes according to uplink-downlink configuration of a serving cell and receiving a power control parameter configuring a first uplink power control subframe set and a second uplink power control subframe set for the uplink subframes. In this case, the first uplink power control subframe set and the second uplink power control subframe set are configured to be independently applied by an offset for transmitting the uplink control information.
