Abstract
A method for performing a contention-based non-orthogonal multiple access in a wireless communication system comprises the steps of: selecting a corresponding group from among a plurality of groups for the non-orthogonal multiple access on the basis of a service class of an upper layer; selecting one of a plurality of reference signal sequences and transmitting a reference signal to which the selected reference signal sequence is applied, in a reference signal resource allocated to the selected corresponding group; and transmitting encoded data to which the repetition frequency, corresponding to the selected corresponding group, or a target bit rate is applied.
