Title:
INFORMATION TRANSMISSION METHOD, DEVICE AND COMMUNICATION SYSTEM SUITABLE FOR NON-ORTHOGONAL MULTIPLE ACCESS
Document Type and Number:
WIPO Patent Application WO/2017/139915
Kind Code:
A1
Abstract:
An information transmission method, device and communication system suitable for non-orthogonal multiple access. The information transmission method comprises: a sending end modulating transfer data into a plurality of constellation symbols; respectively rotating the plurality of constellation symbols a first predetermined angle to obtain a plurality of first symbols; interweaving imaginary and real parts of the plurality of first symbols to obtain a plurality of second symbols; respectively rotating the plurality of second symbols a second predetermined angle to obtain a plurality of third symbols; interweaving imaginary and real parts of the plurality of third symbols to obtain a plurality of fourth symbols; and mapping the plurality of fourth symbols to a plurality of resource particles for transmission. Thus, a higher diversity gain may be obtained, system performance may be further improved, and a larger number of user devices may be reused.
