METHODS AND APPARATUSES FOR NON-ORTHOGONAL MULTIPLE ACCESS RESOURCE UTILIZATION SCALABILITY

摘要

Systems, methods, apparatuses, and computer program products for non-orthogonal multiple access (NOMA) resource utilization scalability are provided. One method may include configuring the number of physical resource blocks (PRBs) allocated for NOMA usage in a cell-specific manner. At least a parameter may be configured and used in determining the number of PRBs allocated for the NOMA. The parameter may refer to at least one of a spreading factor for a spreading based NOMA scheme, or to a repetition number for an interleaver/scrambling based NOMA scheme. The method may also include defining at least one mapping pattern to indicate a mapping of user data to the physical resource blocks.
