AI Technical Summary

Technical Problem

Existing sensing technologies have low sensing accuracy in the field of communications, especially when multiple network devices are sensing in a coordinated manner, making it difficult to accurately determine the position and speed of the sensed object.

Method used

By sending configuration information to multiple network devices, distance and Doppler feature information based on two-dimensional surface echo signals are obtained. Combining signal-to-noise ratio and feature vectors, the error is quantized using the Fisher information matrix, and the sensing capabilities of each network device are dynamically evaluated, thereby improving sensing accuracy and robustness.

Benefits of technology

It enables more accurate determination of the position and velocity of the sensed object, improves the sensing accuracy and robustness, reduces the computational burden, and enhances the overall accuracy of collaborative sensing among multiple network devices.

Abstract

The perception method, device and storage medium provided in the application relate to the field of communication technology. The method comprises: each network device in a plurality of network devices perceiving a plurality of two-dimensional surfaces divided according to an elevation angle dimension in a perception area; determining distance-Doppler information corresponding to each two-dimensional surface based on echo signals received by each network device through each two-dimensional surface in the plurality of two-dimensional surfaces; determining Q sets of perception data corresponding to Q perception objects based on the distance-Doppler information corresponding to the plurality of two-dimensional surfaces; and further determining the position and speed of the Q perception objects based on the Q sets of perception data reported by each network device. In this way, the perception accuracy of the perception objects can be improved.
