    Abstract: Provided are a method and a device for transmitting uplink data by using a non-orthogonal code multiple access scheme in a wireless communication system. Specifically, a terminal receives information on a terminal-specific codebook from a base station. The terminal-specific codebook is included in a codebook for a predefined multi-dimensional modulation. The terminal performs multi-dimensional modulation-based encoding on an information bit on the basis of the terminal-specific codebook so as to generate a complex vector. The terminal performs DFT on the complex vector on the basis of the terminal-specific codebook so as to generate a frequency signal. The terminal transmits uplink data generated by performing IFFT on the frequency signal.
