Abstract: Provided are a method and an apparatus for competition-based transmitting of uplink data in a wireless communication system to which a non-orthogonal multiple access scheme is applied. Particularly, a terminal receives, from a base station, information relating to a predefined modulation pattern for non-orthogonal multiple access. The information relating to the predefined modulation pattern includes a modulation pattern index. The modulation pattern index indicates designation of a terminal-specific modulation order for each resource element in a resource used overlappingly by multiple terminals. The terminal transmits data to the base station using the modulation order designated to each of the resource elements on the basis of the information relating to the predetermined modulation pattern.

Abstract: A method and a device for performing communication by using a non-orthogonal code multiple access scheme in a wireless communication system are provided. Particularly, a terminal receives control information from a base station. The terminal modulates or demodulates a terminal-specific NCC on the basis of the control information. The terminal performs the non-orthogonal code multiple access scheme by using the terminal-specific NCC. The control information includes information on a codeword composed of a Grassmannian sequence. The codeword is included in a codebook predefined for the non-orthogonal code multiple access scheme.

Abstract: According to one embodiment, a distance technique between a transmitter and a receiver for processing a signal in symbol units is presented. According to the embodiment, the transmitter transmits a transmission signal to the receiver through preset first and second frequencies. Then, the transmitter receives, from the receiver, a reception signal corresponding to the transmission signal. The reception signal includes a first reception component corresponding to the first frequency and a second reception component corresponding to the second frequency. The phase difference set by the receiver is applied between the phase of the first reception component and the phase of the second reception component. The phase difference is set on the basis of the difference between a reception time at which the transmission signal is received by the receiver and a processing time at which the transmission signal is processed in the receiver.
