    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.

    Abstract: A disclosure of the present specification provides a method for transceiving data in a next generation mobile communication system. The method may comprise a step of receiving system information from a base station. The system information may comprise: system band information; information regarding a first uplink center frequency and a second uplink center frequency for an uplink band within the system band; and information regarding a first downlink center frequency and a second downlink center frequency for a downlink band within the system band. The method may comprise: a step of receiving, from the base station, a control signal to change the downlink band to a second downlink center frequency; and a step of tuning a radio frequency (RF) unit in order to switch the downlink band from the first downlink center frequency to the second downlink center frequency.

    Abstract: An embodiment of the present invention relates to a method by which a base station transmits a downlink signal in wireless communication system, the method including the steps of: transmitting a demodulation-reference signal (DMRS) approval; determining a long-term channel property from the DMRS of a first slot of an uplink sub-frame received by responding to the DMRS approval; receiving a first reference signal from a second slot of the sub-frame on the basis of the determined long-term channel property; determining a short-term channel property from the first reference signal; determining a pre-coding matrix from the long-term channel property and the short-term channel property; and transmitting a downlink signal through the determined pre-coding matrix.

    Abstract: A method for transmitting a signal by a Device-to-Device (D2D) User Equipment (UE) is disclosed. The method includes mapping a block of complex-valued symbols to Physical Resource Blocks (PRBs), and generating and transmitting a Single Carrier Frequency Division Multiple Access (SC-FDMA) signal after the mapping. If frequency hopping is used during the mapping, a lowest PRB index of the PRBs is changed between a first PRB index and a second PRB index according to a change in a transmission number for a transport block. If the block of complex-valued symbols is a D2D communication signal, the transmission number for the transport block is replaced with a subframe index of a D2D resource pool.
