AI Technical Summary

Technical Problem

In the existing IEEE 802.11be standard, the feedback granularity of measurement reports is insufficient, making it impossible to effectively identify and optimize the Quality of Service (QoS) of specific flow classification services, resulting in resource waste and increased transmission power consumption.

Method used

By including the identifier of the Stream Classification Service (SCS) flow in measurement requests and reports, the feedback granularity of the measurement report is improved. The sender can optimize the sending strategy based on the QoS requirements of the SCS flow, including selecting the appropriate link for data transmission and performing targeted optimization at the receiver.

Benefits of technology

The feedback accuracy of measurement reports is improved, the QoS of specific SCS flows is optimized, resource waste and power consumption are reduced, and the flexibility and throughput of data transmission are enhanced.

Abstract

A communication method and device based on stream classification service are applied to a wireless local area network system supporting an IEEE 802.11 ax next generation Wi-Fi protocol, such as 802.11 be, Wi-Fi 7 or EHT, and 802.11 series protocols such as 802.11 be next generation, Wi-Fi 8, UHR and the like, and can also be applied to a UWB-based wireless personal local area network system, a sensing system and the like. The method comprises the following steps: a receiving end sends a measurement request, correspondingly, a sending end receives the measurement request, and the measurement request comprises an identifier of a stream classification service (SCS) stream; a sending end sends a measurement report, correspondingly, a receiving end receives the measurement report, and the measurement report comprises an identifier of an SCS flow and QoS measurement data of the SCS flow. And the feedback granularity of the measurement report is effectively improved.
