TWO-STAGE RESOURCE SPREAD MULTIPLE ACCESS (RSMA) DESIGN

WIPO Patent Application WO/2019/140239

A1

A two stage scrambling design is provided for generating and decoding Resource Spread Multiple Access (RSMA) modulated streams. A User equipment (UE) scrambles each data stream of a set of data streams using a first scrambling sequence to generate a first set of scrambled data streams, and then scrambles the first set of scrambled data streams using a second scrambling sequence to generate a second set of scrambled data streams, wherein the second scrambling sequence is longer than the first scrambling sequence. The UE then transmits the second set of scrambled data streams. A receiving base station determines the first and second scrambling sequences used by the UE and decodes the transmissions received from the UE based on the determined scrambling sequences.
