    Abstract: Disclosed in the present application is a beam failure recovery method and apparatus, a UE, a base station, and a readable storage medium. The method comprises: a UE determines a target reporting mode for beam failure of a first SCell; if the UE detects that beam failure occurs to the first SCell, the UE reports information of beam failure recovery to a base station by using the target reporting mode; the base station performs beam failure recovery of the first SCell according to the detected information indicating that a beam failure event occurs to the first SCell and/or candidate beam information. According to the present application, a UE may perform beam failure reporting of a SCell in a relatively reliable mode or a relatively reliable mode selected by a base station, so that the system is able to use a reliable beam reporting mode of the SCell to perform beam failure recovery of the SCell.
