    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 codeword for non-orthogonal multiple access. The predefined codeword includes a first spreading code and a second spreading code. The terminal configures a base layer using the first spreading code and configures an enhancement layer using the second spreading code. The terminal transmits a terminal identifier and data to the base station through a competition-based resource which overlappingly uses the base layer and the enhancement layer, wherein the terminal identifier is transmitted through the base layer and the data is transmitted through the enhancement layer.
