Method for decoding V2X signal transmitted by means of transmit diversity method in wireless communication system, and terminal using same

摘要

Provided are a method for decoding a V2X signal transmitted by means of a transmit diversity method in a wireless communication system, and a terminal for applying same. The method comprises: determining a first CS index of a first DM-RS associated with a first antenna port on the basis of a CRC of sidelink control information (SCI) received via a PSCCH; determining a second CS index of a second DM-RS associated with a second antenna port on the basis of reserved bits of the SCI; and on the basis of the first DM-RS having the first CS index applied thereto, and the second DM-RS having the second CS index applied thereto, decoding a V2X signal transmitted via the first antenna port and the second antenna port.
