AI Technical Summary

Technical Problem

Existing Wi-Fi technologies struggle to effectively manage conflicts between IDC services and Wi-Fi services in multi-link devices under ultra-high reliability (UHR) scenarios, leading to decreased network performance and poor user experience.

Method used

By carrying identification information in the radio frame to identify the duration information required for IDC services, and transmitting Wi-Fi PPDU frames in the main link and secondary link, the Wi-Fi service is temporarily stopped before the IDC service is transmitted. The access mechanism of NSTR link pairs is defined to optimize resource allocation to avoid conflicts.

Benefits of technology

It improves the stability of UHR transmission and network performance, reduces interference, and enhances the collaboration capabilities between devices and the overall network efficiency.

Abstract

The embodiment of the invention relates to a communication method, communication equipment and a communication system. The communication method comprises the following steps: determining a first wireless frame; the first wireless frame comprises first identification information, and the first identification information identifies first duration information required for coexistence of an IDC service in a transmission device in a transmission opportunity TXOP of the first device; the first wireless frame is sent; wherein before the IDC service is transmitted, the first device transmits a wireless fidelity physical layer protocol data Wi-FiPPDU frame in a main link and a secondary link, the main link and the secondary link are non-simultaneous transceiving (NSTR) of each other, and a mechanism that the first device comprising an NSTR link pair is respectively accessed in the main link and the secondary link in the presence of the IDC service is defined. The method is suitable for UHR transmission requirements.
