Patent ID: 8345618

Claim:
A method of transmitting a control signal in a multiple antenna system, the method comprising: transmitting, by a user equipment, a control signal on a first physical uplink control channel (PUCCH) through a first transmit antenna in an uplink subframe; and transmitting, by the user equipment, the control signal on a second PUCCH through a second transmit antenna in the uplink subframe, wherein the control signal is mapped to a cyclic shifted sequence, the mapped control signal is transmitted by using a pair of resource blocks in the subframe, and one of a pair of resource blocks occupies different subcarriers with the other of the pair of resource blocks, wherein the control signal on the first PUCCH is mapped to a first cyclic shifted sequence and the control signal on the second PUCCH is mapped to a second cyclic shifted sequence, and wherein the control signal on the first PUCCH and the control signal on the second PUCCH are mapped to different cyclic shifted sequences.
