A method and apparatus for transmitting uplink control information in a wireless communication system is disclosed. A method for transmitting uplink control information in a mobile station of a wireless communication system includes performing reverse repetition coding with respect to first uplink control information, and performing joint coding with respect to the reverse repetition coded first uplink control information and second uplink control information. The first uplink control information has higher priority than the second uplink control information.

The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for transmitting acknowledgement/negative ACK (ACK/NACK) in a wireless communication system which supports carrier aggregation, and to an apparatus for the method. A method in which a terminal transmits ACK/NACK in a wireless communication system that supports carrier aggregation comprises the following steps: receiving one or more physical downlink shared channels (PDSCHs); and transmitting ACK/NACK for said one or more PDSCHs via a physical uplink control channel (PUCCH). A PUCCH format for transmitting ACK/NACK is selected by taking the type of the carrier in which said one or more PDSCHs are received into account.

A method for transmitting a signal via physical uplink control channel (PUCCH) in a wireless communication system and an apparatus for performing the method are provided. Control information bits are modulated to generate N1 modulation symbols, wherein N1 is twice a number of subcarriers in one resource block (RB). The modulation symbols are spread by using various orthogonal codes to generate a plurality of sequences and the generated plurality of sequences are transmitted using different slots of a subframe through different antenna ports, each sequence of the plurality of sequences being mapped on a corresponding single carrier frequency division multiple access symbol in a corresponding slot.

A method for transmitting a user equipment (UE)-triggered channel status information (CSI) is disclosed. A UE transmits a preamble to an eNode B (eNB) through a random access channel (RACH) or a CSI RACH. The UE receives a response allocating a CSI feedback resource or allocating a resource for negotiation from the eNB. The UE transmits the CSI and a UE ID, or only the CSI to the eNB through a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH).

A method for configurating a basic signal allocation unit and a method of transmitting signals using the configurated basic signal allocation unit are disclosed. In particular, a basic frequency domain signal allocation unit is configurated by considering at least one selected from the group consisting of a signaling overhead, a size of a coherent bandwidth and a number of divisors among specific numbers and an OFDM symbol number corresponding to a multiple of a subframe unit, each of the specific numbers multiplied to a predetermined subcarrier spacing to enable a result value of the multiplication to have a difference smaller than a prescribed threshold from a divisor of a system bandwidth. And, a time domain unit is configurated by 1-subframe unit. Accordingly, signaling overhead can be efficiently reduced.
