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: A method and apparatus for handling a soft buffer size in a wireless communication system is provided. It is assumed that a user equipment (UE) is connected to both a long-term evolution (LTE) system and a new radio access technology (NR) system in dual connectivity. The UE determines a first UE capability for the LTE system and a second UE capability for the NR system, determines a total soft buffer size based on the first UE capability and the second UE capability, and shares the total soft buffer size between the LTE system and the NR system based on at least one of a maximum transport block size (TBS) per transmission time interval (TTI) and a number of carriers used in the NR system.

Abstract: The present invention relates to a method and apparatus for a transmission device to transmit a reference signal in a wireless communication system. Specifically, the method includes: a step for receiving the settings of a resource pool composed of uplink resources; and a step for mapping reference signals and data onto a specific uplink resource on the basis of the resource pool settings and N (where N is a natural number) antennas for the transmission device, and is characterized in that the reference signals are mapped to at least one resource element at a specific location on the specific uplink resource, and the data is mapped on the specific uplink resource excluding the at least one specific location to be mutually orthogonal on the basis of one resource axis among the time-frequency resources and so that the data is continuous depending on the number of antennas. The transmitting device is capable of communicating with at least one of another receiving device, a receiving device related to an autonomous driving vehicle, a base station or a network.
