    Abstract: A disclosed feature of the present specification is to provide a method for transmitting a hybrid automatic repeat request (HARQ) acknowledgement/negative-acknowledgement (ACK/NACK) signal using a sidelink. The method may comprise the steps of: receiving from a transmission terminal data in a first time section within a sidelink subframe n; and transmitting a HARQ ACK/NACK signal in a second time section within the sidelink subframe n. A gap may exist between the first time section and the second time section in the sidelink subframe n. The gap can be used for switching between reception and transmission.

    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.

    Abstract: Disclosed are a method for selecting a transmission resource for a transport block (TB) by a user equipment (UE) in a wireless communication system and an apparatus therefor according to various embodiments. Specifically, disclosed are a method for selecting a transmission resource for a transport block (TB) by a user equipment (UE) in a wireless communication system and an apparatus therefor, the method comprising the steps of: arbitrarily selecting one frequency section from among multiple frequency sections divided from a system band at predetermined frequency intervals, and determining a first transmission resource for transmitting the transport block (TB) on the basis of the arbitrarily-selected frequency section; and transmitting the transport block, using the determined first transmission resource, wherein a guard band, which is a frequency band which is not selected as the first transmission resource, is formed in the arbitrarily-selected frequency section.
