Abstract: This application relates to the field of communication technologies, and discloses a communication method and apparatus. On example method includes: a backscatter device receives an excitation signal from an exciter. The backscatter device determines a backscatter signal pattern in a backscatter signal pattern set, where the backscatter signal pattern set includes a plurality of backscatter signal patterns, and backscatter reference signals in the plurality of backscatter signal patterns do not overlap in time domain. The backscatter device modulates a backscatter reference signal and a backscatter data signal on the excitation signal based on the determined backscatter signal pattern, to obtain a backscatter signal. The backscatter device sends the backscatter signal to a receiver.

Abstract: Embodiments of the present invention disclose a signal processing method, apparatus, and system, where the method includes: receiving a downlink signal that carries an uplink signal; and performing first interference cancellation on the uplink signal by using an estimated self-interference signal, so that a remaining amount of interference of the uplink signal is less than a first interference threshold, thereby minimizing out-of-band interference of the uplink signal on the downlink signal without using a plurality of radio frequency front-ends or without using a duplexer on a same radio frequency front-end. In the embodiments of the present invention, no duplexer is adopted, and therefore, difficulty and a cost of base station and system layout can be reduced, and extra energy consumption of a mobile terminal can also be reduced.
