Abstract

The present application relates to the field of mobile communication, in particular to the beamforming technology in the communication system. In a beam processing method, a plurality of continuous symbols to be transmitted in the form of beams are acquired, and if the plurality of continuous symbols include a switching interval for switching between uplink and downlink, a message is sent to the user equipment in the cell , the message is used to notify the user equipment of information that the base station performs beam switching at the switching interval. Through the solution provided in this application, the time overhead of beam switching can be reduced.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to beamforming technology in a communication system. Background technique [0002] Beamforming technology is a combination of wireless technology and digital signal processing technology, and its purpose is to realize directional transmission or reception of directional signals. [0003] Since the beams transmitted by the base station using the beamforming technology are directional, only the user equipment in the direction of the transmission beam can receive the signal transmitted by the base station with a relatively high signal-to-noise ratio. Therefore, in order to enable the signal of the base station to fully cover all the cells of the base station, the base station needs to continuously switch beams, that is, to form beams in different directions by changing the beam transmission direction. Beamforming technologies include digital beamforming and analog...
