Method and device for controlling transmission power for uplink control channel in carrier aggregation system

摘要

Provided are a method of controlling transmission power for an uplink control channel for a terminal to which a plurality of cells are assigned, and a device using the method. The method receives a first set of parameters and a second set of parameters that are used for determining transmission power for the uplink control channel and determines the transmission power for the uplink control channel by using the first set of parameters or the second set of parameters, wherein the first set of parameters or the second set of parameters is used according to one of the cells to which the uplink control channel is transmitted.

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.
