Method for reducing coexistence interference of multiple networks and terminal

Abstract

The invention provides a method for reducing coexistence interference of multiple networks and a terminal, and the method comprises the steps: obtaining a first working channel of a first network anda second working channel of a second network if the terminal employs the first network and the second network for communication at the same time; if the first working channel and the second working channel meet the harmonic interference condition and the harmonic noise of the receiving signal of the interfered network is greater than a preset threshold, adjusting a power amplifier in a signal transmitting link of the interfered network so as to reduce the harmonic noise of the receiving signal of the interfered network; wherein the interference network is the network with the minimum frequencyof the frequency band where the working channel is located in the first network and the second network, and the interfered network is the network with the maximum frequency of the frequency band where the working channel is located in the first network and the second network. According to the method, by improving the linearity of the power amplifier, the harmonic noise of an interfered network receiving signal is reduced, so that the terminal performance is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and a terminal for reducing coexistence interference of multiple networks. Background technique [0002] At present, the fifth-generation mobile communication technology (5G) wireless communication technology has been promoted and commercialized. At the same time, the fourth-generation mobile communication technology (4G) wireless communication technology is still an important communication wireless communication technology. In the future, 4G wireless communication technology and 5G wireless communication technology will exist at the same time. [0003] At present, multiple networks can be used inside the terminal at the same time, for example, when the terminal uses 4G network and 5G network at the same time. The n77 frequency band, n78 frequency band and n79 frequency band of 5G are mainly concentrated in the 3.3GHz to 4.2GHz frequency band. The seco...
