This application provides an information indication method. The method includes: determining, by a terminal device, that communication on a first downlink resource fails, where the first downlink resource is a resource configured by a network device for the terminal device; and sending, by the terminal device, first indication information to a network device on a first uplink resource, where the first indication information is used to indicate that the communication on the first downlink resource fails, the first uplink resource is a resource used to carry second indication information, and lengths of respective information bits of the second indication information and the first indication information are the same, but status bits of the information bits are different. When determining that the communication on the first downlink resource fails, the terminal device sends the first indication information to the network device on the resource that carries the second indication information, and reports failure of communication on a downlink resource by reusing an uplink resource allocated to other indication information. Therefore, failure of the communication on the downlink resource is notified to the base station in a timely manner, and resource overheads can be reduced.
