    摘要: The present invention relates to a method for performing positioning in a cellular-vehicle to everything (C-V2X) system, and a device therefor. A method for performing positioning in a terminal mounted on a positioning vehicle in a C-V2X communication system according to one aspect may comprise the steps of: measuring a time of flight (ToF) by performing road side unit (RSU) and round trip time (RTT) ranging; determining a positioning mode, wherein the positioning mode includes a self-positioning mode and a cooperative positioning mode; measuring the relative positions of surrounding vehicles by using a sensor provided in the positioning vehicle on the basis of the determined positioning mode being the cooperative positioning mode, and storing first positioning measurement information corresponding to the measured relative positions; selecting a surrounding vehicle on which to perform cooperative positioning; transmitting the first positioning measurement information to the selected surrounding vehicle; receiving second positioning measurement information from the selected surrounding vehicle; and determining the current location of the positioning vehicle on the basis of the first and second positioning measurement information.

    摘要: Disclosed are, according to various embodiments, a method for transmitting, by a user equipment (UE), a first collective perception message (CPM) in a wireless communication system supporting a sidelink, and an apparatus therefor. Disclosed are the method and the apparatus therefor, the method comprising the steps of: obtaining first object information on surrounding objects through a sensor; receiving a second CPM including second object information; and transmitting the first CPM including the first object information and location information for the UE, wherein the second CPM further includes information on a location reliability of the second object information, the position information of the UE is corrected by applying an offset, based on the first object information and the second object information being object information for the same object, and the offset is determined by applying a ratio between a first position reliability related to the position information of the UE and the second position reliability included in the second CPM to a distance between an object position based on the first object information and an object position based on the second object information.
