Claim:
1. A method of controlling transmission power of an uplink control channel of a user equipment for which a plurality of cells are configured, the method comprising: receiving a first parameter set and a second parameter set which are used to determine the transmission power of the uplink control channel; determining the transmission power of the uplink control channel by using the first parameter set or the second parameter set; and transmitting information on the uplink control channel using the determined transmission power, wherein the first parameter set or the second parameter set is used according to a cell in which the uplink control channel is transmitted among the plurality of cells, and wherein if the cell in which the uplink control channel is transmitted is a primary cell in which the user equipment performs an initial connection establishment procedure or a connection re-establishment procedure with respect to a base station, the first parameter set is used to determine the uplink control channel transmission power.
