Abstract
A method for receiving, by a terminal, a signal on the basis of a non-orthogonal multiple access scheme in a wireless communication system comprises the steps of: receiving, from a base station, control information including information on a codebook selected for the terminal among pre-defined codebooks for non-orthogonal multiple access and information on a codeword selected from the selected codebook; receiving, from the base station, data for the terminal according to scheduling of the control information; and detecting data for the terminal by performing a multi-user detection (MUD) scheme on the basis of the information on the selected codebook and the information on the selected codeword.
