Claim:
1. A method for transmitting uplink control information performed by a User Equipment (UE) in a wireless communication system, comprising: generating a plurality of hybrid ARQ acknowledgements (HARQ-ACKs); selecting, from among a plurality of resource indices, one first resource index for a first antenna port and two second resource indices for a second antenna port corresponding to the plurality of HARQ-ACKs; transmitting, through the first antenna port to a base station (BS), a first modulation symbol corresponding to the plurality of HARQ-ACKs and a first reference signal for demodulating the first modulation symbol; and transmitting, through the second antenna port to the BS, a second modulation symbol corresponding to the plurality of HARQ-ACKs and a second reference signal for demodulating the second modulation symbol, wherein a transmission resource for the first modulation symbol, a transmission resource for the first reference signal, a transmission resource for the second modulation symbol, and a transmission resource for the second reference signal are defined by the following equation: [Equation] where p wherein n
