AI Technical Summary

⚠Technical Problem

In environmental IoT (A-IoT) systems, the concurrent transmission of a large number of devices on the same time-frequency resources can cause severe hard conflicts, leading to a decrease in system throughput and connection reliability.

⚗Method used

The devices are divided into multiple subgroups, each corresponding to a time block in the access period. The devices autonomously initiate transmission on pre-configured frequency domain resources, and adopt orthogonal or sparse codebook strategies to ensure physical isolation of the devices on the time axis and reduce the signal collision rate.

🎯Benefits of technology

By using physical isolation and codebook strategies along the timeline, the signal collision rate is effectively reduced, ensuring the stable operation of the A-IoT system under high load and improving the system's access reliability and transmission efficiency.

Abstract

The application provides a data transmission method, a communication device, a system and a storage medium, which can be applied to the technical field of wireless communication. In the scheme, when the A-IoT reader monitors that the number of active users in the current cell sharply increases, a time domain grouping offloading strategy is activated, the A-IoT devices in the cell are divided into multiple subgroups, each subgroup corresponds to a time block in the access period, and each A-IoT device is only allowed to initiate uplink data transmission in the time block window corresponding to the subgroup to which the A-IoT device belongs. The scheme requires that the A-IoT device must wait until the specific time block to which the A-IoT device belongs to wake up and establish a connection. By physically isolating the massive concurrent requests on the time axis, the number of potential users competing for the same resource at any time is reduced, the signal collision rate is greatly reduced from the source, and it is ensured that the A-IoT system can still stably run under high load.
