Description

TECHNICAL FIELD The present specification relates to a wireless communication system, and more particularly, to a method of performing positioning based on a harvesting period in a wireless communication and a device therefor. BACKGROUND Wireless communication systems are being widely deployed to provide various types of communication services such as voice and data. In general, a wireless communication system is a multiple access system capable of supporting communication with multiple users by sharing available system resources (bandwidth, transmission power, etc.). Examples of the multiple access system include a code division multiple access (CDMA) system, a frequency division multiple access (FDMA) system, a time division multiple access (TDMA) system, an orthogonal frequency division multiple access (OFDMA) system, and a single carrier frequency division multiple access (SC-FDMA) system, and a multi carrier frequency division multiple access (MC-FDMA) system. Sidelink (SL) refers to a communication scheme in which a direct link is established between user equipments (UEs) and the UEs directly exchange voice or data without intervention of a base station (BS). SL is considered as a solution of relieving the BS of the constraint of rapidly growing data traffic. Vehicle-to-everything (V2X) is a communication technology in which a vehicle exchanges information with another vehicle, a pedestrian, and infrastructure by wired/wireless communication. V2X may be categorized into four types: vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-network (V2N), and vehicle-to-pedestrian (V2P). V2X communication may be provided via a PC5 interface and/or a Uu interface. As more communication devices require a larger communication capacity, there is a need for improved mobile broadband communication, compared to existing radio access technology (RAT). Accordingly, communication systems that take into account services or UEs sensitive to reliability and latency are under discussion, and the next-generation wireless access technology that takes into account improved mobile broadband communication, massive machine type communication (MTC), and ultra-reliable and low latency communication (URLLC) may be referred to as new RAT or new radio (NR). V2X communication may also be supported in NR.
