Abstract: A method whereby a user equipment transmits/receives a reference signal for distance measurement in a wireless communication system according to an embodiment of the present invention comprises: a step of receiving, from a base station, a downlink (DL) positioning reference signal (PRS) including sinusoidal components of different angular frequencies; a step of acquiring a phase difference between the sinusoidal components of the DL PRS; a step of transmitting a first uplink (UL) PRS indicating the phase difference, so as to measure a first distance between the user equipment and the base station at a first point of time; and a step of transmitting a second UL PRS so as to measure a second distance between the user equipment, the position of which has changed after the first point of time, and the base station, wherein the user equipment may configure the same phase difference, acquired via the DL PRS before the first point of time, for the second UL PRS, without receiving an additional DL PRS for measuring the second distance. The user equipment is capable of communicating with at least one of another user equipment, a user equipment related to an autonomous driving vehicle, the base station or a network.

Abstract: Provided are a method and equipment for performing device-to-device communication by sharing an uplink resource and a sidelink resource in a wireless communication system. Particularly, a first terminal transmits a reference signal to a base station. The first terminal receives a downlink control signal from the base station. The downlink control signal includes beam limiting information indicating a beam, which is not used for reducing interference with an uplink signal, when the first terminal transmits a sidelink signal. The first terminal transmits the sidelink signal to a second terminal by using beams excluding the beam indicated by the beam limiting information. The sidelink signal is transmitted through a resource pool in which the uplink resource and the sidelink resource are overlapped in time and frequency domains.

Abstract: Provided are a method and an apparatus for transmitting uplink data on the basis of contention in a wireless communication system. Specifically, a terminal receives, from a base station, allocation information for a contention zone in one resource zone. The allocation information includes a configuration field indicating locations and the number of contention zones. The terminal determines whether repetition of uplink data is to be performed, on the basis of downlink channel information. When it is determined that the repetition of uplink data is to be performed, the terminal transmits, to the base station, uplink data through all contention zones indicated by the configuration field. When it is determined that the repetition of uplink data is not to be performed, the terminal transmits, to the base station, uplink data through one contention zone arbitrarily selected from among all the contention zones indicated by the configuration field.

Abstract: According to one embodiment, a distance technique between a transmitter and a receiver for processing a signal in symbol units is presented. According to the embodiment, the transmitter transmits a transmission signal to the receiver through preset first and second frequencies. Then, the transmitter receives, from the receiver, a reception signal corresponding to the transmission signal. The reception signal includes a first reception component corresponding to the first frequency and a second reception component corresponding to the second frequency. The phase difference set by the receiver is applied between the phase of the first reception component and the phase of the second reception component. The phase difference is set on the basis of the difference between a reception time at which the transmission signal is received by the receiver and a processing time at which the transmission signal is processed in the receiver.
