Abstract: Embodiments of this application provide a beam configuration method and apparatus. The method includes: determining base station scheduling information rank, and determining a direction of arrival power spectrum; determining peak information based on the direction of arrival power spectrum; determining, based on the peak information, beam directions that meet power conditions; selecting, based on a preset filtering condition, at least one candidate beam direction from the beam directions that meet the power conditions; and determining a target beam direction of a terminal from the at least one candidate beam direction based on the base station scheduling information rank, a value of a channel quality indicator CQI, and the direction of arrival power spectrum. In this way, a beam configuration manner on a terminal side is more flexible, to meet requirements of different service scenarios, and improve stability of a communications link.
