Abstract
Disclosed in the present application are an antenna beam management method and related device, used for solving the problem in current large-scale antenna technology wherein the overhead of beam management control signaling is large. The method is: a terminal sending related information of a downlink beam of the terminal to a base station so that the base station determines a first downlink sending beam on the basis of the related information of the downlink beam; the terminal receiving notification information related to the first downlink sending beam send by the base station, the notification information comprising indication information that is used by the terminal to determine at least one first downlink receiving beam; the terminal determining the at least one first downlink receiving beam on the basis of the notification information; and the terminal receiving a downlink signal on the basis of the at least one first downlink receiving beam.
