In the method for radio link failure recovery, a user equipment (UE) detects that a handover failure occurs, and when the UE has a stored conditional handover (CHO) configuration, or when the UE has a stored conditional handover (CHO) configuration and CHO recovery is enabled, the UE reverts back to a configuration used in a source cell. The configuration used in the source cell includes one or more of a physical layer dedicated configuration, a medium access control (MAC) layer configuration, or a semi-persistent SPS configuration.
