The present invention relates to a method for transmitting channel quality control information using two transmission blocks in a wireless access system that supports hybrid automatic retransmit request (HARQ). The method for transmitting channel quality control information according to one embodiment of the present invention comprises: a step in which a terminal receives a physical downlink control channel (PDCCH) signal including downlink control information (DCI); a step of calculating, using the DCI, the number (Q′) of encoded symbols required for transmitting channel quality control information; and a step of transmitting the channel quality control information via the physical downlink control channel (PDCCH) based on the number of encoded symbols.

The present invention relates to a method for transmitting response information on downlink data through multiple information blocks to be bundled in a wireless system in a time division duplex (TDD) mode. The method for transmitting response information according to the present invention comprises the following steps: coding response information on the downlink data; scrambling the coded response information; and transmitting the scrambled response information to a base station, wherein, if a portion of the bits of the coded response information are information bits that indicate ACK/NACK on the downlink data, the scrambling step involves scrambling the coded response information using a specific scrambling sequence, and the specific scrambling sequence includes information on the number of information blocks to be bundled.

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.

The present invention discloses a method for a terminal to transmit control information in a wireless communication system. The method includes encoding a plurality of pieces of control information and transmitting the plurality of encoded control information and data information through a data channel. During the encoding of the plurality of control information, a channel quality indicator (CQI) and a precoding matrix index (PMI) for an entire frequency band are encoded jointly or separately, and each piece of the plurality of pieces of encoded control information and the data information is mapped into a resource block of the data channel, and is then transmitted.
