Claim:
1. A method for transmitting uplink control information (UCI) in a wireless communication system, the method performed by a user equipment and comprising: receiving a physical downlink shared channel (PDSCH); configuring a subframe for transmitting periodic channel state information (CSI); selecting a first resource or a second resource if a transmission of acknowledgement/not-acknowledgement (ACK/NACK) information for the PDSCH and a transmission of the periodic CSI coincide in the subframe; generating a bit sequence comprising the ACK/NACK information and the periodic CSI; and transmitting the bit sequence in the subframe using the selected resource, wherein the first resource is one fixed resource pre-configured by a higher layer signal and the second resource is one resource indicated by an ACK/NACK resource indicator (ARI) field among a plurality of resources configured by a higher layer signal, wherein the location of the ACK/NACK information and the periodic CSI in the bit sequence is dependent on the selected resource used for transmission of the bit sequence, wherein when the bit sequence is transmitted using the first resource, the periodic CSI is arranged first, based on the most significant bit (MSB) of the bit sequence, and the ACK/NACK information is arranged next, and wherein when the bit sequence is transmitted using the second resource, the ACK/NACK information is arranged first, based on the MSB of the bit sequence, and the periodic CSI is arranged next.
