Solution Overview
Problem
Existing wireless communication systems struggle to efficiently manage and coordinate multiple modalities of traffic types, such as audio, video, and sensor data, in augmented, virtual, and mixed reality applications, leading to inefficiencies and potential degradation in user experience.
Innovation Solution
A method and device that identify and tag different service data flows (SDFs) for various modalities, allowing coordinated transmission through wireless communication nodes, ensuring appropriate quality of service (QoS) for each modality, thereby enhancing the management of multi-modal traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple modalities of traffic types are transmitted through existing wireless communication systems, then the system can support augmented, virtual, and mixed reality applications, but the coordination and management of multi-modal traffic becomes inefficient and user experience degrades
Solution Approach 1:
The patent segments multi-modal traffic into distinct Service Data Flows (SDFs), where each SDF corresponds to a specific modality (audio, video, sensor data). This segmentation allows the wireless communication system to handle each traffic type separately with dedicated QoS parameters, resolving the coordination inefficiency while maintaining support for diverse traffic types.
Solution Approach 2:
The patent introduces a new dimension for traffic management by mapping SDFs to QoS flows and applying tags at multiple levels (SDF level and QoS flow level). This dimensional approach adds structure to the traffic management system, enabling efficient coordination of multi-modal traffic without compromising versatility.
2Reliability
If tags are generated for each service data flow to indicate association within multi-modal flow, then coordinated transmission is achieved, but the complexity of traffic management increases
Solution Approach 1:
The patent introduces tags as intermediary elements that facilitate the association between SDFs within a multi-modal flow. These tags act as mediators that enable coordinated transmission without requiring complex direct management mechanisms. The tags provide a standardized interface for indicating relationships between different traffic flows, simplifying the overall management complexity.
Solution Approach 2:
The patent changes the management approach by introducing tag parameters that can be applied to SDFs and QoS flows. Instead of complex management protocols, the system uses parameter-based tagging to indicate associations and coordinate transmission. This parameter change transforms the management mechanism from procedure-heavy to parameter-driven, reducing operational complexity.
3Reliability
If quality of service metrics are optimized for each modality, then user experience is enhanced, but the system requires more sophisticated traffic management mechanisms
Solution Approach 1:
The patent applies local quality by assigning specific QoS parameters and tags to individual SDFs based on their modality requirements. Each traffic flow receives customized QoS treatment (e.g., latency constraints for audio, bandwidth for video) without requiring the entire system to be reconfigured. This localized approach enhances QoS for each modality while keeping the overall management mechanism relatively simple through standardized tagging.

AI summary
Systems and methods for multi-modal signaling may include a first device which identifies a plurality of modalities relating to respective traffic types of a multi-modal flow of an application, for traffic of the application to be sent to a second device. The first device may generate a first tag for a first service data flow (SDF) for a first modality and a second tag for a second SDF for a second modality. The first tag and the second tag may indicate an association between the first SDF and the second SDF within the multi-modal flow. The first device may transmit, via a transmitter to a wireless communication node, one or more signals indicating the first tag and the second tag, for transmission of the traffic between the first device and the second device.
