Abstract: Disclosed are a method and a device for transmitting uplink control information (UCI) by a terminal in a wireless communication system. The UCI transmission method comprises the steps of: generating an encoding information bit stream by performing channel coding for a UCI bit stream; generating complex modulation symbols by performing modulation for the generated encoding information bit stream; spreading the complex modulation symbols in block-wise on the basis of an orthogonal sequence; and transmitting the spread complex modulation symbols to a base station. The encoding information bit stream is generated by a channel coding for circularly repeating the UCI bit stream.

Abstract: A method for transmitting uplink data in a wireless communication system, and a user equipment (UE) therefore are discussed. The method according to one embodiment includes configuring transmission of a sounding reference signal (SRS) in a subframe of a first component carrier (CC) among a plurality of CCs; and transmitting the uplink data to a base station in the subframe of a second CC among the plurality of CCs. The SRS, whose transmission is configured in the first CC, is not transmitted in a symbol in the subframe of the first CC, when the transmission of the SRS and the transmission of the uplink data happen to overlap in the symbol.
