Abstract: Provided are a method and a device for setting a space division connection between terminals for V2X communication in a wireless communication system. Specifically, a second terminal requests a connection setting with a first terminal from a base station. The second terminal measures a signal of the first terminal and generates a first beam group pair comprising a transmission beam group of the first terminal, which has a large signal size, and a reception beam group of the second terminal. When the second terminal receives a signal of a third terminal by using the reception beam group of the second terminal, the second terminal measures a signal of the third terminal and generates a second beam group pair comprising a transmission beam group of the third terminal, which has a large signal size, and the reception beam group of the second terminal.

Abstract: Provided is a method and device for receiving a signal in a wireless communication system to which a multiple-transmission technique is applied. A proposed wireless communication system proposes a method for maximizing packet transmission within a target time in multiple paths. Specifically, a terminal receives, from a first base station, multiple-transmission activation information and control information for transmission of a transmission block. The terminal decodes the multiple-transmission activation information and the control information, and receives the transmission block from the first base station and a second base station. At this time, the multiple-transmission activation information includes a multiple-transmission activation indicator indicating that the first base station and the second base station can transmit the transmission block until a preconfigured time.

Specifically, a first terminal transmits a random access preamble for requesting a connectionless transmission. The first terminal receives a random access response comprising scheduling information of the uplink data. The first terminal transmits uplink data and a reference signal from a first resource configured on the basis of scheduling information of the uplink data and information indicating the CP length of the reference signal.
