Abstract: Provided in one disclosure of the present specification provides a method for transmitting a physical uplink control channel (PUCCH) including uplink control information (UCI), when more than five cells are used by a user equipment (UE) according to carrier aggregation. The method may comprise the steps of: encoding UCI of K bits, which exceeds 20 bits, and outputting encoded bits of N bits; and mapping on resource elements (RE) in an uplink subframe, without applying an orthogonal cover code (OCC) to the encoded N bits, wherein the uplink subframe may include two symbols, and wherein each symbol may include 12 subcarriers on a frequency axis and six or seven symbols on a time axis. The mapping step may be carried out according to a symbol index and from among symbols remaining after excluding symbols for a demodulation reference signal (DMRS) and a subcarrier index.
