US Patent 11991541 Link failure recovery method and apparatus

This application provides a link failure recovery method and apparatus. A terminal is configured to send first request information to a network device on the same resource (namely, a first resource) when detecting that a link of any one of a plurality of cells fails or the links of more than one of the plurality of cells fail, to notify the network device that a link of at least one of the cells fails. In this way, in a multi-carrier scenario resource overheads are reduced as compared to the solution of using separate resources to notify link failures in multiple cells.
