Title: BEAM MANAGEMENT METHOD AND DEVICE THEREFOR
Abstract:
Disclosed in the embodiments of the present invention are a beam management method and a device therefor, the method comprising the following steps: a network device sends first information that carries at least one public identifier to a user equipment, wherein the at least one public identifier indicates an association between a transmitted beam of the network device and a received beam of the user equipment; the user equipment monitors the first information that is sent by the network device and that carries the at least one public identifier; the user equipment sends, to the network device, second information that carries a successful reception identifier or a default identifier according to the monitoring result, wherein the successful reception identifier indicates that the user equipment has monitored at least one public identifier, and the default identifier indicates that the user equipment has not monitored the at least one public identifier; and the network device receives the second information that is sent by the user equipment and that carries the successful reception identifier or the default identifier. According to the embodiments of the present invention, a handshake between the associated public identifiers of a base station and a user equipment for transmitted and received beams may be implemented, thereby improving the communication robustness of a beam-based access system.
