Method for transmitting sidelink signal in wireless communication system

An apparatus for a user equipment (UE) in a wireless communication system, the apparatus comprising:

• at least one processor;
• and
• at least one memory operably coupled to the at least one processor and storing at least one instruction causing the at least one processor to perform operations,
• wherein the operations include:
• mapping a first complex-valued modulation symbol associated with a sidelink control signal to a control resource included in sidelink resources, mapping at least one second complex-valued modulation symbol associated with a sidelink data signal to a data resource included in the sidelink resources, and mapping a preconfigured value to a plurality of subcarriers included in the sidelink resources;
• generating the sidelink control signal and the sidelink data signal by orthogonal frequency division multiplexing (OFDM)-modulating the at least one first complex-valued modulation symbol, the at least one second complex-valued modulation symbol, and the preconfigured value;
• and
• transmitting the sidelink control signal and the sidelink data signal, and
• wherein the plurality of subcarriers include at least one of a first subcarrier having a highest frequency index in the sidelink resources or a second subcarrier having a lowest frequency index in the sidelink resources.
