Abstract: A communication method that may be applied to a base station is provided. The method includes: obtaining first information; and switching from a narrow beam state to a wide beam state if the first information satisfies a first switching condition, where the narrow beam state indicates that a message is sent by sweeping a target area by using N narrow beams, N is an integer greater than 0, the wide beam state indicates that a message is sent by sweeping the target area by using M wide beams, and M is an integer greater than 0.

Abstract: Example communications methods and apparatus are described. One example method includes generating a first signal by a base station. The base station performs cyclic delay diversity (CDD) weighted processing on the first signal to obtain a second signal, and performs densified beam weighted processing on the second signal to obtain a third signal. The third signal is sent by the base station via an antenna. According to the foregoing method, the CDD weighted processing is performed on the first signal generated by the base station, so that time diversity can be obtained when the first signal is transmitted. In addition, the densified beam weighted processing is performed on the second signal obtained after the CDD weighted processing, so that a quantity of beams scanned by the base station can be increased.

Abstract: A beamforming-based communication method includes: obtaining cell information; when the cell information meets a preset low-load condition, dividing to-be-processed broadcast messages into a plurality of broadcast message groups; determining, based on a preset correspondence between a broadcast message and a broadcast beam, a broadcast beam group corresponding to each broadcast message group and a broadcast beam for sending no broadcast message in each time window; sending the broadcast message group in each time window by using the broadcast beam group; and shutting down, in each time window, the broadcast beam for sending no broadcast message. Some broadcast beams are used in each time window to send the broadcast message, and the broadcast beam for sending no broadcast message is shut down.

Abstract: A method, device and system for regulating power consumption are provided in the embodiments of the present invention. A method for regulating power consumption includes: obtaining, by a base station, an application point and a configuration parameter; sending, by the base station, an indication message to a terminal according to the application point and configuration parameter; regulating, by the base station, the power consumption of the base station by using the configuration parameter at the application point; the configuration parameter comprises cell antenna information or system bandwidth information; the indication message instructs the terminal to use the configuration parameter at the application point. Under the condition that user's normal communication is remained, the number of cell antennas or the cell bandwidth is dynamically changed. This reduces the power consumption of the network device.
