1. A method for a first apparatus to transmit a physical sidelink control channel (PSCCH) and a physical sidelink shared channel (PSSCH) to a second apparatus, the method including:
determining whether a first demodulation reference signal (DMRS) symbol among a plurality of DMRS symbols for the PSSCH in at least one PSSCH subchannel related to the PSSCH is occupied by a resource area for the PSCCH in a whole frequency band of one PSSCH subchannel among the at least one PSSCH subchannel;
determining a location of a reference symbol in a PSSCH resource in which a second sidelink information (SCI) is mapped based on whether the first DMRS symbol is occupied by the resource area for the PSCCH in the whole frequency band of the one PSSCH subchannel;
mapping the second SCI based on the location of the reference symbol in the PSSCH resource; and
transmitting the second SCI to the second apparatus through the PSSCH.
