Abstract

A near-field beam search method, including: a base station determines a grid where a terminal is located from at least one type of preset grid of a near-field coverage range of the base station; the base station determines a target transmitting beam codebook according to the grid and a base station transmitting beam codebook set corresponding to the preset grid, where the base station transmitting beam codebook set includes a transmitting beam codebook corresponding to each grid in the preset grid; the base station sends information of the target transmission beam codebook to the terminal, and the terminal determines a target receiving beam codebook from a terminal receiving beam codebook set corresponding to the preset grid according to the information; the base station sends a signal to the terminal by using the target transmitting beam codebook, and the terminal receives the signal by using the target receiving beam codebook.
