Title:
METHOD AND APPARATUS FOR CONTROLLING HARMONIC INTERFERENCE
Document Type and Number:
WIPO Patent Application WO/2020/220196
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application are a method and apparatus for controlling harmonic interference. The method is applicable to a dual-connectivity communication system. The method comprises: collecting, from a first uplink signal of first connectivity belonging to dual connectivity transmitted by a transmitter, a first harmonic interference signal causing harmonic interference to a downlink signal of second connectivity belonging to the dual connectivity; adjusting the first harmonic interference signal to a target amplitude and a target phase; and superposing the adjusted first harmonic interference signal with a received signal received by a receiver to control a second harmonic interference signal generated by 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 apparatus provided in the embodiments of the present application are low in complexity, do not increase the size of a terminal device, and can effectively control harmonic interference.
