Problems solved by technology
The radio frequency module is mainly used to transmit radio frequency signals, and the interference signal coupled to the radio frequency module will produce sideband radiation spurious with the main frequency modulation such as GSM / LTE, thus affecting the quality of the transmitted radio frequency signal
[0004] And because the interference signal generated on the power supply has low frequency and strong energy, it cannot be suppressed by means of filter capacitors on the terminal
In one implementation, the sideband radiation spurious problem caused by fast charging is solved by directly unplugging the fast charging source, and this solution has a great impact on the user's charging experience

Embodiments of the present application provide a method, device, and terminal for reducing spurious sideband radiation in a charging scenario. The method includes obtaining the service status of at least one of the call service and the data service of the terminal; At least one of the two data services is in the service state, then determine the first communication frequency band; obtain the current charging power of the charging unit; if the interference frequency generated by the current charging power is greater than or equal to the first frequency interference threshold, then send the first indication to the charging unit information, the first indication information is used to indicate that the current charging power is adjusted to the first target charging power, wherein the interference frequency generated by the first target charging power is less than the first frequency interference threshold, so that the charging power is adjusted to the first target charging power After the power is turned on, the interference frequency generated by the first target charging power is lower than the interference frequency generated by the charging power before adjustment, thereby reducing the generation of sideband radiation spurious to the current communication frequency band.
Description
technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a method, device and terminal for reducing spurious sideband radiation in a charging scenario. Background technique [0002] In order to meet people's demand for fast charging of mobile terminals, fast charging technology has emerged as the times require. The fast charging technology mainly shortens the charging time by increasing the charging power. Although the fast charging technology shortens the charging time, it will generate a strong interference signal on the fast charging source, and the generated interference signal will have a negative impact on some functions of the terminal, thus affecting the user experience. [0003] For example: the radio frequency module used in the terminal includes an internal power module and a radio frequency module. Since the radio frequency module has the problem of poor isolation between the internal power modu...
