Abstract

The embodiment of the invention provides a beam switching method and device, relates to the technical field of communication, and solves the problem of frequent beam switching caused by short shielding of beams. The method comprises the following steps that network equipment predicts: on a terminal side, the change amplitude of the beam intensity of a first beam at the next moment relative to thebeam intensity at the current moment; if it is determined that the change amplitude is greater than the preset threshold, the network equipment acquires the identifier of the second beam and the azimuth angle of the second beam; the network equipment sends the identifier of the second beam and the azimuth angle of the second beam to the terminal, and acquires the azimuth angle of the first beam from the terminal; the network equipment compares the azimuth angle of the first beam with the azimuth angle of the second beam, and if the azimuth angle of the first beam is equal to the azimuth angleof the second beam, beam switching is not performed; if the azimuth angle of the first beam is not equal to the azimuth angle of the second beam, the terminal switches from the first beam to the second beam. The embodiment of the invention is applied to beam switching.

Description

technical field [0001] Embodiments of the present application relate to the field of communication technologies, and in particular, to a beam switching method and device. Background technique [0002] Millimeter wave has the advantages of wide spectrum, high reliability, good directivity, and extremely short wavelength, but it also has the disadvantage of not being easy to pass through obstacles. [0003] Currently, after receiving the first beam, the receiving end will measure parameters such as signal to interference plus noise ratio (SINR) and reference signal receiving power (RSRP) of the first beam. Then, the receiving end judges the value of the measured parameter and the value of the preset threshold. When it is determined that the value of the measured parameter is smaller than the preset threshold, the receiving end switches from the first beam to the second beam. [0004] In complex urban road environments, millimeter waves are easily blocked by vehicles / building...
