Abrégé
(EN)
Embodiments of the invention provide a method and a device for transmitting a signal based on resource mapping in an NOMA (Non-Orthogonal Multiple Access) system, and relate to the technical filed ofcommunication, wherein the method comprises the steps of: acquiring preset number of resource groups; for the each resource group, determining a corresponding relationship between each variable node of the resource group and channel nodes in physical resource blocks of the other resource groups to serve as a new corresponding relationship; and transmitting signals to each user according to a corresponding relationship included in the preset number of resource groups and the determined new corresponding relationship. Through adoption of the method provided by the embodiment of the invention, adetection bit error rate of a signal receiver can be reduced, and system reliability can be improved.
