Abstract: Provided are a beam management method and apparatus, and a network side device, a terminal and a storage medium. The method comprises: a receiving terminal sending beam information used for beam management, wherein the beam information comprises uplink beam information or downlink beam information; determining, according to the beam information, specified information used for the beam management, wherein the specified information comprises terminal location information and/or beam quality information; and determining, according to the specified information and network deployment information, a sending beam used for signal transmission and/or a change trend of the sending beam, wherein the signal transmission comprises uplink signal transmission or downlink signal transmission. Therefore, the embodiments of the present application solve the problems of large overheads and time delay caused by frequently carrying out beam scanning processes in a high-speed scenario, and optimize a beam management strategy, thereby saving beam scanning time and beam overheads.
