Method for selecting pucch transmission in a carrier aggregation system and a device therefor

Abstract

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for selecting PUCCH transmission at power limitation situation in a carrier aggregation system, the method comprising: configuring multiple Physical Uplink Control Channels (PUCCHs) for the UE; generating multiple uplink control information, wherein each of the multiple uplink control information is to be transmitted via corresponding PUCCH to the eNB at a same time; selecting one of multiple PUCCHs configured for the UE if the UE is not able to transmit the multiple uplink control information on the multiple PUCCHs at the same time; and transmitting corresponding uplink control information on the selected PUCCH to the eNB.
