The disclosure relates to a method and a device for reporting a beam measurement report. The method includes: obtaining, by a terminal, a beam measurement result, in which the beam measurement result includes channel measurement parameters corresponding to n reference signals RSs included in a set of target RSs and channel measurement parameters corresponding to m other RSs except the set of target RSs, the set of target RSs is corresponding to a set of target transmission configuration indication TCI states; transmitting, by the terminal, the beam measurement report to the network access equipment when the beam measurement result satisfies a preset condition; and receiving, by the terminal, TCI state update information from the network access equipment, in which the TCI state update information is configured to indicate TCI states included in the updated set of target TCI states.
