The text embodiments of the present disclosure relate to the technical field of wireless communications, and more particularly to a data transmission method, system and device, which are used for solving the problem existing in the prior art that the utilization rate of radio resources is relatively low due to the fact that an orthogonal manner can only reach the inner bound of a multiuser capacity bound. The method in the text embodiments of the present disclosure comprises: conducting, by a sending end, sending processing on signals of one or more user equipment; and conducting non-orthogonal feature pattern mapping on the signals of the one or more user equipment on which the sending processing is conducted, so that signals of different user equipment are superposed at corresponding radio resources, and according to the result of the non-orthogonal feature pattern mapping, sending the processed signals of the one or more user equipment. Since non-orthogonal superposition can be conducted on signals of one or more user equipment at radio resources, non-orthogonal multiple access transmission is realized, thereby increasing the utilization rate of radio resources. |
