The sending device can correspondingly scatter the excitation signal sent by the base station according to the bit value to be sent, so that the receiving device determines the corresponding bit value according to the energy of the signal received in the sending time interval, and therefore the low-power-consumption or zero-power-consumption backscattering communication is completed by utilizing the excitation signal sent by the base station. The method provided by the embodiment improves the coverage capability of the network, and can be applied to the internet of things, such as MTC, IoT, LTE-M, M2M and the like.)
