This application relate to a communication method and apparatus, a chip system, and an electronic device, and relate to the field of electronic technologies. The method is applied to a first communication module in a first operating system, the first operating system is run on a first processor core, the first communication module is configured to communicate with a second communication module in a second operating system, the second operating system is run on a second processor core, and the first processor core and the second processor core are located in a same electronic device. The method includes: receiving a first request from the second communication module, where the first request indicates an identity of the second communication module; when identity verification of the second communication module succeeds, processing the first request; and sending, to the second communication module, a first response obtained by processing the first request.
