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.

Abstract: In the method, a terminal device may send first indication information on a first uplink resource based on information about a spatial relation parameter, to indicate that a link failure occurs in a ith cell in N second cells. The information about the spatial relation parameter is information about a spatial relation parameter used to send a channel and/or a signal of a first cell, and the first uplink resource is an uplink resource of the first cell. Therefore, the network device does not need to configure a plurality of uplink resources that are associated with a plurality of reference signal resources of a second cell and that are used to indicate that a link failure occurs in the second cell, thereby reducing resource overheads.
