The embodiment of this application discloses a beam management method, device and system, which relates to the field of communication and solves the problem of how to shorten the time of beam cooperation between the terminal and TRP. Specific schemes are as follows: the measured beam set size N, N beam indexes, candidate beam set size K and active beam set size L configured by terminal receiving base station; X beams are determined according to the measured beam set size N, N beam indexes, candidate beam set size K and active beam set size L; X beams constitute active beam set; X beams are sent to base station with X beam indexes and X beams. Beam index is the index of X beams included in the set of active beams. The embodiment of this application is used to solve the problem of shortening the time of beam cooperation between the terminal and TRP.
