Abstract
Embodiments of the present application provide a beam search method, device, system, electronic equipment and readable medium. The method comprises selecting a terminal radio frequency link from a plurality of terminal radio frequency links as a selected terminal radio frequency link, selecting a plurality of first point columns in a preset terminal beam grid, and receiving a reference signal transmitted by a base station in an omnidirectional manner using a communication beam corresponding to the first point column; determining the average spectral efficiency of the communication beam corresponding to the first point column; determining a terminal high spectral efficiency region in the terminal beam grid based on the difference in average spectral efficiency between the first point columns; determining a target communication beam corresponding to the selected radio frequency link in the terminal high spectral efficiency region; and selecting a communication beam with a direction close to that of the target communication beam as a target communication beam corresponding to other terminal radio frequency links in the plurality of terminal radio frequency links except the selected terminal radio frequency link. The embodiments of the present application effectively reduce the beam search complexity and shorten the time for determining the preferred communication beam.
