Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently communicating Quality of Service (QoS) elements, particularly in high-throughput scenarios, leading to suboptimal performance and user experience.
Innovation Solution
A mechanism is introduced to signal QoS parameters using a Scalable Coding Scheme (SCS) procedure, enabling precise communication of QoS elements across multiple links, optimizing data transmission and reception.

If traditional QoS communication methods are used in wireless systems, then basic QoS parameters can be transmitted, but the communication efficiency and throughput are suboptimal in high-data-rate scenarios
Solution Approach 1:
The patent applies dynamics by making the QoS element structure adaptable and configurable based on service requirements. The QoS element can dynamically include different parameter combinations (such as 5QI, ARP, GBR, MBR, Maximum Bit Rate, Minimum Bit Rate) depending on the specific service type and quality requirements, allowing the system to optimize between throughput efficiency and parameter accuracy for different traffic flows
Solution Approach 2:
The patent implements parameter changes by introducing a standardized set of QoS parameters that can be selectively applied to different service types. By defining specific parameters like 5QI (5GI Quality of Service Identifier), ARP (Allocation and Retention Priority), GBR (Guaranteed Bit Rate), and MBR (Maximum Bit Rate), the system can adjust the level of detail and precision of QoS signaling to match the requirements of various wireless services, thereby improving both throughput efficiency and reliability
2Reliability
If detailed QoS parameters are communicated for every data flow, then service quality can be optimized, but the signaling overhead and system complexity increase
Solution Approach 1:
The patent applies segmentation by dividing QoS parameters into different categories and levels of detail. Rather than transmitting all possible QoS parameters for every data flow, the system segments parameters into essential ones (like 5QI and ARP) that are always communicated, and additional detailed parameters (like GBR, MBR, Maximum Bit Rate, Minimum Bit Rate) that are only included when specifically required by the service type. This reduces signaling overhead while maintaining service quality
Solution Approach 2:
The patent implements universality by creating a standardized QoS element structure that can serve multiple service types and scenarios. The same basic QoS element framework can accommodate different service requirements by selectively including relevant parameters, making the signaling mechanism universally applicable across diverse wireless services without requiring separate complex signaling procedures for each service type

For example, an apparatus may be configured to cause an Extremely High Throughput (EHT) wireless communication station (STA) to set a control field including presence signaling information corresponding to a plurality of parameter fields, the presence signaling information configured to indicate, for a parameter field of the plurality of parameter fields, whether the parameter field is to be present or absent in a Quality of Service (QoS) element; and to transmit a frame including the QoS element, the QoS element including the control field, wherein the presence or absence of the plurality of parameter fields in the QoS element is configured according to the presence signaling information in the control field.
