Abstract: The present application provides a transmission failure recovery method and apparatus, a device, and a storage medium. A reference signal corresponding to a group of control resource sets CORESETs or a beam failure detection reference signal BFD RS set is determined; and a transmission failure recovery request is transmitted to a network device if the reference signal meets a predefined condition, where the transmission failure recovery request is used for indicating the network device to perform transmission failure recovery on the group of CORESETs. Since network device is triggered to enable a transmission failure recovery mechanism on a group of CORESETs when a reference signal corresponding to the group of CORESETs meets a predefined condition, a transmission delay for data on a transmission point with failed beam transmission is reduced, thereby improving communication quality.
