A method of transmitting a channel quality indicator (CQI)/precoding matrix indicator (PMI) using a PUSCH region in a system employing a MIMO antenna system in which transmission is performed through a plurality of layers includes encoding the CQI/PMI using one channel encoder, and transmitting the encoded CQI/PMI using some or all of the layers. Accordingly, it is possible to transmit uplink control information through a PUSCH region using a plurality of layers. ## Claims ### Claim 1 A method of transmitting control information using an uplink data channel, the method comprising: transmitting control information using a first resource region of a first layer; and transmitting data using a second resource region of a second layer corresponding to the first resource region. ### Claim 2 (depends on 1) The method of claim 1, wherein the control information is CQI/PMI (Channel Quality Indicator and Precoding Matrix Indicator) information. ### Claim 3 (depends on 1) The method of claim 1, further comprising transmitting control information or data using a third resource region of a third layer corresponding to the first resource region. ### Claim 4 (depends on 1) The method of claim 1, further comprising transmitting control information using a third resource region of a third layer corresponding to the first resource region and transmitting data using a fourth resource region of a fourth layer corresponding to the first resource region. ### Claim 5 (depends on 1) The method of claim 1, further comprising transmitting control information using a third resource region of a third layer corresponding to the first resource region, wherein a first part of the control information is transmitted using the first resource region of the first layer and a second part of the control information is transmitted using the third resource region of the third layer. ### Claim 6 (depends on 1) The method of claim 1, wherein a first codeword mapped to the first layer has a higher MCS (Modulation and Coding Scheme) level than a second codeword mapped to the second layer. ### Claim 7 (depends on 1) The method of claim 1, wherein a first codeword mapped to the first layer has a lower codeword number than a second codeword mapped to the second layer when the first codeword and the second codeword have the same MCS level. ### Claim 8 A method of transmitting control information using an uplink data channel, the method comprising: encoding the control information; separating the encoded control information into N parts; and transmitting the N parts of control information using N layers. ### Claim 9 (depends on 8) The method of claim 8, wherein the control information is channel quality indicator (CQI), precoding matrix indicator (PMI), ACK/NACK or rank indicator (RI). ### Claim 10 (depends on 8) The method of claim 8, wherein the N layers are all layers mapped to a same codeword when the control information is CQI/PMI. ### Claim 11 (depends on 8) The method of claim 8, wherein the N is total number of layers when the control information is ACK/NACK or RI. ### Claim 12 A method of transmitting control information using an uplink data channel, the method comprising: encoding the control information; multiplying the encoded control information by a first code and transmitting the control information multiplied by the first code through a first layer; and multiplying the encoded control information by a second code and transmitting the control information multiplied by the second code through a second layer. ### Claim 13 A method of receiving control information using an uplink data channel, the method comprising: receiving a first codeword through a first layer; and receiving a second codeword through a second layer, wherein data is received through a first resource region of the first layer and control information is received through a second resource region of the second layer corresponding to the first resource region when the second codeword has a higher MCS(Modulation and Coding Scheme) level than the first codeword. ### Claim 14 (depends on 13) The method of claim 13, wherein the data received through the first resource region is part of the first codeword.
