Description

This application claims priority to Chinese Patent Application No. 202311200143.2, filed with the China National Intellectual Property Administration on September 18, 2023 and entitled "ANTENNA STATE CONTROL METHOD, CHIP, ELECTRONIC DEVICE, AND READABLE STORAGE MEDIUM", which is incorporated herein by reference in its entirety. TECHNICAL FIELD This application relates to the field of electronic technologies, and specifically, to an antenna state control method, a chip, an electronic device, and a readable storage medium. BACKGROUND To meet an increasing use requirement of people, forms of electronic devices are increasingly rich. Wearable devices, as electronic devices for daily wear, play an irreplaceable role in people's lives. Usually, the wearable device needs to have a miniaturized appearance to be suitable for daily wear, and further needs to support a plurality of communication standards to meet a plurality of communication requirements of people. A common smartwatch is used as an example. Two antennas are usually disposed in the smartwatch. One antenna is used for cellular mobile communication, and the other antenna is used for Bluetooth communication. However, due to a small volume of the smartwatch, the two antennas are deployed in narrow space of the smartwatch and there is mutual coupling, resulting in poor performance of the antennas and affecting communication quality. SUMMARY This application provides an antenna state control method and apparatus, a chip, an electronic device, a computer-readable storage medium, and a computer program product, to improve antenna performance of a second antenna. According to a first aspect, an antenna state control method is provided, including: obtaining a pre-state of a first communication system, where the pre-state is a state that the first communication system is to enter at a second moment after a first moment; and if the pre-state is a non-working state, outputting a target antenna tuning parameter at the first moment, where the target antenna tuning parameter is used to indicate that an antenna tuning switch is in a target tuning state, the antenna tuning switch is configured to tune a tuning state of a first antenna of the first communication system, and in the target tuning state, antenna performance of a second antenna meets a preset performance requirement. When a Modem of the first communication system does not work, the antenna tuning switch may be switched to a switch logic state that can enable good antenna performance of the second antenna corresponding to a second communication system. In this case, the second antenna may work in a tuning state in which the antenna performance meets the preset performance requirement, to ensure communication quality of the second communication system when the first communication system does not work. In some possible implementations, a time difference between the first moment and the second moment is less than or equal to a preset time difference threshold, to ensure that the target antenna tuning parameter effectively acts on the second antenna when the first communication system does not work, and to ensure the antenna performance of the second antenna. In some possible implementations, the non-working state is a sleep state when the first communication system is in an idle state or a radio resource control RRC connected state. When the Modem is in the idle (Idle) state or the RRC state, the modem periodically enters the sleep state to reduce power consumption. The Modem may output the target antenna tuning parameter at a moment before entering the sleep state to control the antenna tuning switch to switch to the switch logic state that can enable good antenna performance of the second antenna corresponding to the second communication system, to ensure that the antenna performance of the second antenna meets the preset performance requirement. In some possible implementations, the non-working state is a sleep state in a network search cycle. When the Modem is in a network search state, the modem also periodically enters the sleep state. The Modem outputs the target antenna tuning parameter at a moment before entering the sleep state in each network search cycle to control the antenna tuning switch to switch to the switch logic state that can enable good antenna performance of the second antenna corresponding to the second communication system, to ensure that the antenna performance of the second antenna meets the preset performance requirement. In some possible implementations, the non-working state is a state in an airplane mode. When an electronic device enters the airplane mode under an operation of a user, the electronic device does not need to perform communication of the first communication system. In this case, the Modem is in the non-working state. Before the Modem enters the non-working state, the target antenna tuning parameter may be output first to control the antenna tuning switch to remain in
