All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms "first," "second," and the like in the description and claims of the present application and in the above-described drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The electronic device according to the embodiment of the present application may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, which have wireless communication functions, and various forms of User Equipment (UE), Mobile Stations (MS), terminal devices (terminal device), and the like.

At present, an existing interference control method is mainly used for solving harmonic interference or adjacent channel interference, and when a Low-Power Wide-Area Network (LPWAN) and a Cellular Network (Cellular) or a Wireless Fidelity (Wi-Fi) exist at the same time:

as shown in fig. 1A, for harmonic interference, the existing solution is to add a filter in the radio frequency transmission path of LPWAN network to suppress its harmonic interference to WIFI and cellular networks, for example: the Sub _1G frequency band of the LPWAN network interferes with WIFI and the high-frequency band of the cellular network, and a filter is added in a radio frequency transmitting channel of the LPWAN network.

As shown in fig. 1B, for adjacent channel interference, the existing solution generally achieves the purpose of increasing the antenna isolation between the two by increasing the spatial distance, so as to solve the mutual interference between adjacent frequency bands of LPWAN and WIFI/cellular network.
