The embodiment of the invention provides a signal transmitting method, a device and a communication system. The method includes: transmitting the signal transmitter for multiple user equipment transmission symbols are superimposed to form superimposed symbols; the superposition symbols are the symbol of the rotation rotation formed after the phase; and using the first antenna transmits the superposition of symbols and using the second antenna transmits the rotation symbol. By the embodiment of the invention, the channel conditions of a plurality of user devices can be differentiated so as to give full play to the gain of the NOMA in the microcell.
