Abstract
A beam failure recovery method and device are provided. The method includes: after a beam failure event or a beam failure recovery event is triggered, monitoring a physical downlink control channel (PDCCH) scrambled with a C-RNTI in a first CORESET for beam failure recovery; and/or monitoring a PDCCH scrambled with a C-RNTI in a second CORESET, where resources corresponding to the first CORESET are different from resources corresponding to the second CORESET.
