Abstract: 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.

Abstract: This application provides a communication method, apparatus, and device, and a storage medium. The method includes: A first communication device sends first information to a second communication device, where the first information includes transmission indication information and at least one first code block group CBG of a first transport block TB, and the transmission indication information indicates a length of the first TB and/or a location of the at least one first CBG in the first TB. Based on the transmission indication information in the first information, at least one CBG of the first TB can be transmitted between the first communication device and the second communication device, to avoid always transmitting the entire TB. This reduces information transmission duration, improves transmission efficiency, and reduces resource consumption, to reduce power consumption of the communication devices.
