AI Technical Summary

Technical Problem

Existing technologies face challenges in achieving high-precision beam scanning and tracking for reconfigurable intelligent surfaces (RIS) due to their larger area and narrower beams, leading to increased resource costs and difficulty in precise beam alignment.

Method used

A method and apparatus for determining the direction of arrival (DOA) using a reconfigurable intelligent surface (RIS) by configuring a codebook value, measuring a target reference signal reflected by the RIS, and determining the DOA based on the measurement result, which enhances beam scanning precision and reduces tracking difficulty.

Benefits of technology

The method improves beam scanning precision and lowers tracking difficulty by effectively utilizing the RIS's beam scanning resources, enabling more accurate beam alignment and positioning.

Abstract

Embodiments of the present disclosure provide a DOA determining method and device, a storage medium and an electronic device. The method comprises: determining a target reference signal and a codebook value corresponding to the target reference signal, and configuring the codebook value to a reconfigurable intelligent surface (RIS); obtaining a measurement result obtained after the target reference signal is reflected to a receiving end by means of the RIS, and the target reference signal is measured by the receiving end, wherein the RIS correspondingly reflects the reference signal according to the codebook value; and determining a target direction of arrival (DOA) on the basis of the measurement result.
