Abstract: The present invention relates to a Vehicle-to-X (V2X) communication method performed by a terminal in a wireless communication system. The method comprises: determining priority of information related to the V2X communication; selecting a transmission time interval (TTI) on the basis of the priority; and transmitting the information on the basis of the selected TTI. If the information related to the V2X communication is information having high priority, a first TTI is selected, and if the information related to the V2X communication is information having relatively lower priority than the information having high priority, a second TTI is selected.

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.
