1. A transmission terminal performing vehicle-to-everything (V2X) communication, the transmission terminal comprising:
a processor configured to generate sidelink control information (SCI); and
a transceiver configured to transmit the generated SCI to a reception terminal through a physical sidelink control channel (PSCCH) and a physical sidelink shared channel (PSSCH),
wherein a decision on whether to allocate a demodulation reference signal (DMRS) of the PSSCH, and the PSCCH, to the same orthogonal frequency division multiplexing (OFDM) symbol is made based on a number of subchannels and at least one size thereof,
wherein, when a number of subchannels is at least two and sizes of the subchannels are at least 20 physical resource blocks (PRBs), the DMRS of the PSSCH, and the PSCCH, are allocated to the same OFDM symbol of a common subchannel.
