Abstract: This application provides a communication method and apparatus. The communication method includes: A network device sends a first message to a first terminal device UE, where the first message includes information about a first resource, and the first resource is to be used to transmit a second message; and when the network device receives the second message from the first UE by using the first resource, the network device determines that the first UE is not faulty, where the second message indicates that the first UE is not faulty. Therefore, the network device may determine, based on the second message sent by the first UE, that the first UE is not faulty. This ensures that service reliability is not affected by a fault of a terminal device, avoids forced termination of service transmission, and ensures transmission reliability.

Abstract: In an indication information receiving method, a first terminal device receives first indication information from a first network device, and sends information about at least one HARQ process of the first terminal device to the first network device based on the first indication information, where the information about the at least one HARQ process includes a process number of a first HARQ process. The first terminal device receives first data from the first network device through the first HARQ process. This can improve reliability during data transmission.

Abstract: A data transmission method includes receiving first information. The first information is useable to indicate that a hybrid automatic repeat request (HARQ) function of a HARQ process associated with a first configured grant is enabled or disabled. The first configured grant is configured by radio resource control (RRC) signaling. The method further includes performing data transmission by the first configured grant based on the first information.
