Abstract

The embodiment of the invention discloses a method and device for controlling harmonic interference. The method is applied to a dual-connection communication system, and comprises the following steps:acquiring a first harmonic interference signal causing harmonic interference to a downlink signal of a second connection belonging to dual connection from a first uplink signal of the first connection belonging to the dual connection transmitted by a transmitter; adjusting the first harmonic interference signal to a target amplitude and a target phase; and superposing the adjusted first harmonicinterference signal with a received signal received by the receiver to control a second harmonic interference signal generated by the transmission of the first uplink signal in the received signal, the received signal comprising the downlink signal and the second harmonic interference signal. The method and device provided by the embodiment of the invention are low in complexity, do not increase the size of the terminal equipment, and can effectively control harmonic interference.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and in particular to a method and device for controlling harmonic interference. Background technique [0002] With the evolution of the communication system, terminal equipment usually needs to achieve dual reception and dual transmission in the case of dual connections. In this case, the nonlinearity of the internal RF device of the terminal equipment may cause self-interference problems in the terminal equipment. The wave interference problem is more serious. In the related art, the harmonic interference is reduced by adding an electromagnetic shield structure, but this will increase the volume of the terminal device. Contents of the invention [0003] Embodiments of the present application provide a method and device for controlling harmonic interference, which are beneficial to eliminating harmonic interference existing in dual connectivity communication. [0004] In ...
