Abstract: Provided are a method and an apparatus for transmitting uplink data in a wireless communication system. 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 the uplink data, a reference signal selected by the terminal and terminal identification information of the terminal from a first overlapping resource utilized by a second terminal. The first terminal receives, as a response for the uplink data, a response signal comprising a terminal identification information field containing terminal identification information corresponding to each reference signal.

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 are a method and an apparatus for transmitting a scheduling request in a wireless communication system. Particularly, a terminal receives, from a base station, allocation information for an SR resource and allocation information for an SPS resource. The terminal transmits a scheduling request through the SR resource or the SPS resource. The allocation information for the SR resource indicates that the SR resource is allocated to a first period. The allocation information for the SPS resource indicates that the SPS resource is allocated to a second period. When the scheduling request is transmitted through the SPS resource, the scheduling request is not transmitted through a predetermined plurality of subframes including the SPS resource.

Abstract: A method and a device for receiving a signal in a wireless communication system to which a multiplex transmission technique is applied are provided. The wireless communication system proposed therein suggests a method for performing multiplex transmission when base stations within a network are synchronized. Particularly, a terminal receives, from a first base station, control information for the transmission of an M number of transmission blocks. The control information includes information for allocating multiplex transmission resources available for the first base station and a second base station during a predetermined subframe. The terminal receives the M number of transmission blocks from the first base station and the second base station via the multiplex transmission resources. Here, the M number of transmission blocks receives from the first base station and the M number of transmission blocks received from the second base station are decoded by using the same reference signal.
