Abstract: Provided are a method and a device for performing communication using a non-orthogonal code multiple access scheme in a wireless communication system. Specifically, a terminal divides a terminal identifier into a first field, a second field, a third field and a fourth field and selects a first reference signal, a second reference signal, a third reference signal and a fourth reference signal. On the basis of the first reference signal, the second reference signal, the third reference signal or the fourth reference signal, the terminal transmits contention-based data to a base station. The first reference signal is selected on the basis of the first field and the maximum number of reference signals. The second reference signal is selected on the basis of the second field and the maximum number of reference signals. The third reference signal is selected on the basis of the third field and the maximum number of reference signals. The fourth reference signal is selected on the basis of the second field and the maximum number of reference signals.
