1. A near-field beam search method, wherein the method is applied to a terminal and the method comprises:
receiving information of a target transmitting beam codebook sent by a base station; wherein the target transmitting beam codebook is a transmitting beam codebook corresponding to a grid where the terminal is located and being from a base station transmitting beam codebook set corresponding to a preset grid of a near-field coverage range of the base station;
determining, according to the information of the target transmitting beam codebook, a corresponding target receiving beam codebook from a terminal receiving beam codebook set corresponding to the preset grid; and
receiving, using the target receiving beam codebook, a signal sent by the base station using the target transmitting beam codebook.
