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. Particularly, a terminal receives control information from a base station. The terminal selects a terminal-specific codeword or receives allocation information of the terminal-specific codeword on the basis of the control information. The terminal transmits uplink data by using the terminal-specific codeword. The terminal-specific codeword is determined as a codeword having a value with a low peak-to-average power ratio (PAPR), when the terminal is located on the outside of a cell. The terminal-specific codeword is determined as a codeword having a value with a high PAPR, when the terminal is located in the center of the cell.

Abstract: A method by which a terminal transmits feedback information comprises the steps of: determining, in predetermined resource units for receiving the broadcast information in a broadcast resource region, whether broadcast information collides; selecting a first shared resource in a shared resource region corresponding to a first broadcast resource in which the conflict occurs in the broadcast resource region, on the basis of a pre-defined mapping rule of the broadcast resource region and the shared resource region; and transmitting, in the selected first shared resource, feedback information including information on the occurrence of the collision, wherein the broadcast resource region is a resource region, which is defined so as to transmit or receive the broadcast information, and the shared resource region can be determined as a resource region shared between a plurality of terminals. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

Abstract: Provided are a method and an apparatus for transmitting uplink data on the basis of contention in a wireless communication system. Specifically, a terminal receives, from a base station, allocation information for a contention zone in one resource zone. The allocation information includes a configuration field indicating locations and the number of contention zones. The terminal determines whether repetition of uplink data is to be performed, on the basis of downlink channel information. When it is determined that the repetition of uplink data is to be performed, the terminal transmits, to the base station, uplink data through all contention zones indicated by the configuration field. When it is determined that the repetition of uplink data is not to be performed, the terminal transmits, to the base station, uplink data through one contention zone arbitrarily selected from among all the contention zones indicated by the configuration field.
