AI Technical Summary

Technical Problem

In the Internet of Things (IoT) of the environment, existing technologies have not fully explored how to effectively transmit carrier waves to achieve information transmission, resulting in insufficient communication reliability.

Method used

A carrier transmission method is provided, in which a carrier is transmitted through a first communication device, each carrier is associated with one or more D2R transmissions, and the carrier is transmitted at a suitable frequency domain location by satisfying specific conditions or by being instructed by a second communication device, thereby supporting backscatter communication of A-IoT devices.

Benefits of technology

This improves the reliability of D2R transmission in A-IoT devices, ensuring that the carrier is transmitted at the appropriate frequency domain position, thus achieving stable information transmission.

Abstract

A carrier wave transmission method and apparatus, a device and a storage medium, relating to the technical field of communications. The method comprises: a first communication device sends one or more carrier waves, each carrier wave being associated with one or more D2R transmissions, the carrier wave transmissions and the D2R transmissions associated with the carrier waves satisfying a first condition, and / or the carrier transmissions being indicated by a second communication device (1010). The method enables carrier waves to be transmitted at appropriate frequency domain positions, and ensures that A-IOT devices can perform backscattering on the basis of the carrier waves, thereby completing D2R transmission, and improving the reliability of D2R transmission.
