The present disclosure relates to a method and device for providing a V2X service in a next generation radio access technology (new RAT). The present embodiments may provide a method and device for performing sidelink communication by a transmission terminal, the method comprising the steps of: receiving, from a base station, one or more pieces of DMRS pattern information and a resource information set comprising information about one or more sidelink resources; selecting, on the basis of the resource information set, one sidelink resource for performing sidelink communication; selecting, on the basis of the selected one sidelink resource, a particular DMRS pattern from among the one or more pieces of DMRS pattern information; and transmitting a PSCCH and a PSSCH in one slot by using the selected sidelink resource, and transmitting, on the basis of the particular DMRS pattern, a DMRS from a particular symbol of the PSSCH.

Method for performing sidelink communication and device therefor

Provided are a method and device for providing vehicle-to-everything (VX) services in next generation wireless access technology (New RAT). The method controls the sidelink HARQ feedback operation by a terminal. A PSSCH scheduled by a PSCCH including sidelink control information is received from a transmitting terminal. Wireless resources of a PSFCH including HARQ feedback information regarding the PSSCH are determined and allocated in one symbol. The PSFCH, allocated in the one symbol, are repeatedly transmitted to the transmitting terminal in two consecutive symbols.

Sidelink HARQ feedback transmission method and device thereof

The present disclosure relates to a method and device for providing a V2X service in a next generation radio access technology (new RAT). The present embodiments provide a method for performing sidelink communication by a terminal and a device therefor, the method comprising the steps of: receiving sidelink synchronization block (SSB) configuration information including synchronization information for sidelink communication; monitoring a SSB monitoring slot configured on the basis of the SSB configuration information; and receiving a SSB in the SSB monitoring slot, wherein the SSB comprises a sidelink primary synchronization signal (S-PSS), a sidelink secondary synchronization signal (S-SSS), and a physical sidelink broadcast channel (PSBCH), and the S-PSS, the S-SSS, and the PSBCH are allocated to N consecutive symbols in the SSB monitoring slot.

The present disclosure relates to a method and a device for providing a V2X service in a next generation radio access technology (new RAT). The present embodiments relate to a method for a terminal to control a sidelink HARQ feedback operation, the method comprising the steps of: receiving, from a transmitting terminal, group cast sidelink data through a physical sidelink shared channel (PSSCH); determining, on the basis of positional information of the transmitting terminal, whether to transmit HARQ feedback information of the group cast sidelink data; and, when it is determined to transmit the HARQ feedback information, transmitting the HARQ feedback information.
