    摘要: According to one embodiment of the present disclosure, provided is a method in which a first device performs sidelink communication. The method may comprise: a step for determining at least one PRS resource for transmitting at least one PRS for sidelink positioning; a step for transmitting, to a second device, the at least one PRS on the basis of the at least one PRS resource; a step for receiving, from the second device, a PSCCH and a PSSCH associated with the PSCCH; a step for determining at least one PSFCH resource for transmitting the PSCCH or at least one PSFCH related to the PSSCH to the second device; and a step for transmitting, to the second device, the at least one PSFCH on the basis of the at least one PSFCH resource.

    摘要: One embodiment relates to a method for a transmission UE (User Equipment) to measure a channel in a wireless communication system, the method comprising: a step in which the transmission UE transmits a channel state information-reference signal (CSI-RS) to a reception UE; and a step in which the transmission UE receives channel state information (CSI) on the basis of the CSI-RS from the reception UE, wherein the CSI-RS is transmitted on a second transmission resource which is wider than a first transmission resource used by the transmission UE, and the CSI indicates a channel state measured on the basis of the second transmission resource.

    摘要: In an embodiment of the present disclosure, proposed is a method in which a first UE transmits a signal to a second UE in a wireless communication system, the method including: a step in which the first UE receives a first signal from the second UE; a step in which the first UE acquires the distance between the first UE and the second UE on the basis of the received first signal; a step in which the first UE selects, on the basis of the calculated distance, a numerology for transmitting a second signal, or a transmit resource in which the numerology is set; and a step in which the first UE transmits the second signal to the second UE on the basis of the selected numerology or the transmit resource. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

    摘要: An embodiment is a method for a user equipment (UE) to transmit a phase-tracking reference signal (PTRS) related to sidelink in a wireless communication system, the method comprising the steps of: generating demodulation reference signals (DMRSs) related to a physical sidelink shared channel (PSSCH); generating a PTRS related to the PSSCH; and transmitting the PTRS and at least a portion of the DMRSs, wherein a DMRS sequence mapped to a prescribed position in a first PSSCH symbol in which the DMRSs are transmitted is used for generating the PTRS, and the prescribed position corresponds to a frequency location at which the PTRS is transmitted and includes a frequency location at which the generated DMRSs are not transmitted.
