A method of coding and transmitting channel quality control information through a physical uplink control channel (PUCCH) is disclosed. The method of transmitting channel state control information (CQI and/or PMI) in a wireless access system includes performing channel coding with respect to the channel state control information according to a payload size of the channel state control information, performing rate matching with respect to the channel state control information coded through channel coding according to physical uplink control channel (PUCCH) format 3, and transmitting the channel state control information using the PUCCH format 3.

The present application relates to a method in which a terminal performs channel interleaving in a multi-antenna wireless communication system. More particularly, the method comprises the following steps: constructing both channel quality indicator (CQI) information and coded data information into preset bit-wide vectors to generate a first interleaver input vector sequence; repeating both rank indicator (RI) information and acknowledgement/negative acknowledgement (ACK/NACK) information per the number (NL) of transmission layers to generate a second interleaver input vector sequence of preset bit-wide vectors and a third interleaver input vector sequence of preset bit-wide vectors; mapping the first interleaver input vector sequence, the second interleaver input vector sequence, and the third interleaver input vector sequence to an interleaver matrix, respectively; and reading the interleaver matrix by a column basis to generate an output vector sequence. The preset bit-wide is defined by the product of a modulation order (Qpm) and the number (NL) of transmission layers.

The present invention relates to a wireless communication system, and more particularly, to a method and apparatus for transmitting uplink control information in a wireless communication system. A method for multiplexing uplink control information and uplink data and for transmitting the multiplexed uplink control information and uplink data according to one embodiment of the present invention comprises the following steps: encoding a first transmission block and a second transmission block to generate a first codeword and a second codeword; mapping the first codeword and the second codeword to one or more layers, respectively; and transmitting, via one or more antenna ports, each layer to which the first codeword and the second codeword are mapped, wherein the uplink control information is multiplexed only to either the first transmission block or to the second transmission block.

A user equipment (UE) transmits uplink control information (UCI) of 3 bits or more to a base station (BS) after modulating the UCI into 1-bit or 2-bit sub-UCI units. Here, the UE maps each 1-bit or 2-bit sub-UCI unit to one of a plurality of corner constellation points regardless of modulation order of data which is multiplexed with the UCI. The corner constellation points are points having a maximum Euclidean distance from among a plurality of constellation points corresponding to the modulation order.
