Abstract
Techniques for a user equipment to perform uplink communication in a wireless communication system. The user equipment performs operations that include: receiving configuration information for a codebook set related with a modulation scheme; receiving a UL grant including a specific codeword index; selecting a codebook based on the specific codeword index included in the codebook set; and transmitting data based on the selected codebook, wherein the codebook set includes a plurality of codebooks predefined for non-orthogonal coded multiple access (NCMA) scheme based communication, and wherein the codebook set is configured based on a spreading factor or an overloading factor.
