A communication method and apparatus are applied to the field of wireless communication technologies. A first communication device receives first indication information sent by a second communication device, where the first indication information is carried on a synchronization link and indicates the first communication device to stop receiving an asynchronous link associated with the synchronization link. The first communication device stops, based on the first indication information, receiving the asynchronous link. The first communication device may further receive second indication information sent by the second communication device, where the second indication information is carried on the synchronization link and indicates the first communication device to start receiving the asynchronous link. The first communication device starts, based on the second indication information, receiving the asynchronous link.
