Abstract

A communication method of a terminal with another terminal through a sidelink comprises: determining, by a first user device, one or more radio resource control (RRC) configurations comprising information of a demodulation reference signal (DMRS) for vehicle-to-everything (V2X) communication between user devices; determining, based on the one or more RRC configurations, a Physical Sidelink Control Channel (PSCCH) DMRS for a PSCCH; determining, based on a cyclic redundancy code of the PSCCH, an identifier; determining, based on the identifier, an initialization value associated with a Physical Sidelink Shared Channel (PSSCH) DMRS for a PSSCH; and via one or more orthogonal frequency division multiplexing (OFDM) symbols, transmitting, by the first user device to a second user device, the PSCCH DMRS and the PSSCH DMRS.
