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.

Abstract: Provided are a method and equipment for transmitting uplink data by using a non-orthogonal code multiple access technique in a wireless communication system. Particularly, a terminal receives, from a base station, allocation information on physical resource blocks. The terminal acquires a spreading factor on the basis of the number of physical resource blocks included in the allocation information. The terminal determines a NoMA codebook set on the basis of the spreading factor. The terminal transmits uplink data generated on the basis of terminal-specific codewords included in the NoMA codebook set.
