Wireless Traffic Specification Bitmap Grouping for Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems in artificial reality applications, such as VR and AR, face challenges in reducing latency, which can lead to judder and motion sickness due to the delay in rendering images corresponding to user movements, especially when multiple traffic identifiers share similar characteristics but are communicated separately, increasing bandwidth and power consumption.
Innovation Solution
The proposed solution involves grouping or bundling traffic identifiers with similar characteristics into a single traffic specification (TSPEC) element, using a bitmap to indicate valid information and direction, allowing the system to ignore unnecessary traffic stream identifiers and optimize communication by sharing QoS characteristics, thereby reducing latency and improving power efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple traffic identifiers are communicated separately with individual TSPEC elements, then each traffic stream can be managed independently, but bandwidth consumption and power usage increase
Solution Approach 1:
The patent combines multiple traffic identifiers (TIDs) with similar QoS characteristics into a single TSPEC element using a bitmap field. This merging approach reduces the number of separate TSPEC elements needed, thereby decreasing bandwidth consumption and power usage while maintaining independent management capability through the bitmap structure that identifies each TID within the consolidated element.
2Reliability
If multiple traffic identifiers are communicated separately with individual TSPEC elements, then each traffic stream can be managed independently, but communication overhead increases
Solution Approach 1:
Multiple TIDs are merged into a single TSPEC element through the use of a bitmap field that efficiently encodes multiple traffic identifier references. This consolidation reduces the quantity of communication overhead by eliminating redundant TSPEC element structures while preserving the ability to manage each traffic stream independently through the bitmap's individual bit positions.
3Loss of time
If traffic specification is optimized by grouping TIDs, then latency is reduced, but system complexity increases
Solution Approach 1:
The patent introduces a bitmap parameter within the TSPEC element that enables efficient grouping of multiple TIDs. This parameter change allows the system to reduce latency by consolidating traffic specifications while managing complexity through the standardized bitmap structure, which provides a systematic way to handle multiple TIDs without requiring complex configuration logic.
4Productivity
If a bitmap is used to indicate multiple TIDs in a single TSPEC element, then bandwidth efficiency improves, but processing complexity increases
Solution Approach 1:
The bitmap parameter enables efficient encoding of multiple TID references within a compact structure, improving bandwidth efficiency by reducing the number of bytes required to specify multiple traffic streams. The processing complexity is managed through the regular structure of the bitmap, which allows systematic interpretation of each bit position corresponding to a specific TID.
