    Abstract: A method and a device to transmit a reference signal (RS) in a wireless communication system are disclosed. The device transmits control information and a first type RS for demodulating the control information through a control region comprising 1 first OFDM (Orthogonal Frequency Division Multiplexing) symbol of a subframe; and transmits data through a data region comprising a predetermined number of OFDM symbols following the control region of the subframe. Here, the first type RS can be used also for demodulating the data when a predetermined condition is met.

    Abstract: Provided is a non-orthogonal multiple access method, which: randomly selects a physical resource for performing non-orthogonal multiple access among the contention-based data transmission areas defined in advance; selects a reference signal sequence for a contention-based data transmission through the selected physical resource; selects a contention resource for the contention-based data transmission; selects a scrambling sequence to be applied to data transmission in the contention-based data transmission; and transmitting a data channel including data and a reference signal corresponding to the selected reference signal sequence through the selected physical resource, wherein the data channel is transmitted by allowing the selected scrambling sequence to be applied thereto.

    Abstract: A method of receiving a downlink (DL) signal by a user equipment (UE) operating on a frequency band above 6 GHz in a wireless communication system is discussed. The method includes receiving system information including first information related to one or more synchronization signal (SS) and PBCH (SS/PBCH) block groups and second information related to one or more SS/PBCH blocks within each of the one or more of SS/PBCH block groups; and receiving the DL signal in resources other than resources used for the one or more SS/PBCH blocks within each of the one or more of SS/PBCH block groups indicated by the first and second information.

    Abstract: The present invention discloses a method for a base station to transmit a synchronization signal block in a wireless communication system. Particularly, the method includes the steps of mapping a plurality of synchronization blocks to a plurality of symbols within a specific time unit, and transmitting a plurality of the synchronization signal blocks mapped to a plurality of the symbols to a user equipment. In this case, at least one synchronization signal block is mapped to each of half time units having a half-length of the specific time unit.

    Abstract: A method for transmitting an uplink control channel for a terminal configured to support multiple transmission time interval (TTI) lengths in a wireless communication system according to an embodiment of the present invention is performed by the terminal and may comprises the steps of: receiving a first physical downlink shared channel (PDSCH) according to a first TTI length at a first time point; receiving a second PDSCH according to a second TTI length differing from the first TTI length at a second time point; and when TTIs for transmitting uplink control channels for the received first PDSCH and second PDSCH overlap, transmitting uplink control information for the first PDSCH and second PDSCH on a physical uplink control channel (PUCCH) having the shorter TTI length among the first TTI length and the second TTI length.
