Abstract: A method for reducing signal interference and related products are provided. The method is applied to a wireless fidelity (Wi-Fi) circuitry of an electronic device. The method includes the following. Send session establishment request information to a new radio (NR) circuitry. Receive session establishment response information from the NR circuitry. Set a working state of the Wi-Fi circuitry to a first state if it is determined, according to the session establishment response information, that there is signal interference between the Wi-Fi circuitry and the NR circuitry, and a current state of the NR circuitry is an idle state. Adjust the working state of the Wi-Fi circuitry to a second state from the first state if there is still signal interference between the Wi-Fi circuitry and the NR circuitry and the current state of the NR circuitry is a connected state.
