A method for uplink transmitting control information from a user equipment in a wireless communication system comprises selecting a specific point among a plurality of points distributed into a symbol space, corresponding to control information, the symbol space including a modulation dimension and a sequence dimension; mapping a signal corresponding to the specific point with a control channel including single carrier-frequency division multiple access (SC-FDMA) symbols; and transmitting the control channel. Preferably, the specific point belongs to the sequence dimension.

The present invention relates to a method in which user equipment transmits a non-periodic sounding reference signal in a wireless communication system. In detail, the method comprises: a step of receiving a downlink control channel from a base station; a step of decoding a downlink control information (DCI) format contained in the downlink control channel; a step of checking a non-periodic sounding reference signal transmission instruction in the DCI format; and a step of transmitting a non-periodic sounding reference signal to the base station in accordance with the transmission instruction. Preferably, if the downlink control channel is received via an nth subframe, the non-periodic sounding reference signal is transmitted via an (n+k)th subframe (where k≦4).

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 a physical downlink control channel (PDCCH); receiving a physical downlink shared channel (PDSCH) indicated by the PDCCH; and transmitting ACK/NACK for the PDSCH via a physical uplink control channel (PUCCH). A PUCCH format for transmitting ACK/NACK is selected by taking the number of aggregated carriers into account.
