AI Technical Summary

Technical Problem

The increase in the number of backscattering devices and data traffic has led to frequent signal collisions, which has affected the communication performance of backscattering IoT devices and increased power consumption.

Method used

Backscattering devices are divided into different categories using a clustering algorithm. They are grouped according to time delay requirements and orthogonal coding parameters. Excitation signals are sent to each group of devices in sequence, and uplink signals returned in batches are received. This method enables the orderly transmission of backscattering device information on a large scale.

Benefits of technology

This reduces the number of times signal collisions and backscattering devices repeatedly transmit information, thereby reducing power consumption and improving communication efficiency.

Abstract

This application discloses a backscatter communication method, apparatus, electronic device, and storage medium, belonging to the field of communications. The method includes: acquiring device information of multiple backscattering devices; the device information includes the latency requirement of each backscattering device; clustering the multiple backscattering devices according to the device information to obtain M groups; determining the average latency of each group of backscattering devices according to the latency requirement; sequentially sending excitation signals to each group of backscattering devices in ascending order of average latency; receiving uplink signals returned by the multiple backscattering devices; the uplink signals are obtained by each backscattering device encoding and modulating the received excitation signals based on corresponding orthogonal coding parameters. This achieves ordered signal transmission of large-scale backscattering device information, reducing collisions and the number of times backscattering devices repeatedly transmit information, thereby reducing power consumption.
