Abstract: This application provides an example communication method and an example apparatus. The method includes a first network device generates first indication information to indicate a first downlink resource. Second indication information indicates a second downlink resource. Because the first indication information may indicate whether the second indication information exists, if a terminal device detects the first indication information in the first time unit, and the first indication information indicates that the second indication information does not exist in the first time unit, the terminal device may stop a blind detection process on the second indication information in advance.
