    Abstract: 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.

    Abstract: Presented in the present specification is a method for a receiving terminal supporting a sidelink. The receiving terminal according to the present specification acquires a synchronization for setting a symbol boundary, applies the same symbol boundary for a plurality of receiving signals, and can set a receiving window on the basis of the symbol boundary. The receiving terminal can acquire a propagation delay applied to a plurality of wireless signals through a first wireless signal among the plurality of wireless signals, and can adjust a starting time of the receiving window for decoding a second wireless signal through the propagation delay or can feed back information related to a transmission timing to a transmission device for transmitting the second wireless signal. Therefore, an efficient decoding technique for a second wireless signal having a characteristic newer than that of a conventional technique is presented.

    Abstract: The present application provides a method for receiving a downlink signal by a terminal in a wireless communication system. Specifically, the method comprises the steps of: receiving a downlink control signal, a first downlink data signal, a first downlink demodulation reference signal for the first downlink data signal in a first time unit; and receiving a second downlink data signal and a second downlink demodulation reference signal for the second downlink data signal in a second time unit, wherein the downlink control signal includes information on a first antenna port for a reference signal, the first antenna port being quasi-co-located (QCL) with an antenna port for the first downlink demodulation reference signal, and information on a second antenna port for a reference signal, the second antenna port being quasi-co-located (QCL) with an antenna port for the second downlink demodulation reference signal.

    Abstract: The present invention relates to a method and apparatus for transmitting and receiving an acknowledgement/negative-acknowledgement (ACK/NACK) by a terminal for vehicle-to-everything (V2X) communication in a wireless communication system. Particularly, the method comprises the steps of: receiving a configuration for a resource pool for V2X communication; for a particular wireless resource in a resource pool, when a reception time point of a first ACK/NACK and a transmission time of a second ACK/NACK have been simultaneously configured, determining a use of the particular wireless resource; and transmitting and receiving one ACK/NACK selected from the first ACK/NACK and the second ACK/NACK, on the basis of the use of the particular wireless 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.
