Dynamic Communication Frame Header Formatting for Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face inefficiencies in processing headers, particularly in high data rate communications where large headers at the receiver cause bottlenecks, and in low data rate communications where minimizing header overhead is crucial to increase system capacity.
Innovation Solution
The method involves formatting communication frames to place all headers at the beginning of the frame for large payload packets, optimizing processing efficiency, and arranging headers with their associated payloads for smaller packets, depending on the communication type, such as VoIP or high throughput data communications like UMB or LTE.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If headers are placed with their associated payloads in low data rate communications, then header overhead is minimized and system capacity is increased, but processing efficiency deteriorates in high data rate communications
Solution Approach 1:
The patent implements dynamic header formatting that adapts to communication conditions. The transmitter determines whether to place headers at the beginning of frames or with associated payloads based on real-time assessment of communication type (low vs. high data rate), allowing the system to optimize for either header overhead reduction or processing efficiency depending on the scenario
Solution Approach 2:
The invention changes the structural parameter of frame formatting based on communication requirements. By varying the header placement position (before payload vs. with payload) according to data rate conditions, the system transforms a static formatting approach into a flexible one that can address both contradictory requirements under different operating conditions
2Productivity
If headers are placed at the beginning of frames for high data rate communications, then processing efficiency is improved, but header overhead increases for low data rate communications
Solution Approach 1:
The system dynamically adjusts header placement based on communication type detection. For high data rate communications, headers are placed at the beginning of frames to enable efficient processing. For low data rate communications, headers are placed with their associated payloads to minimize overhead, thus adapting the formatting strategy to current operational needs
Solution Approach 2:
The invention modifies the frame structure parameter (header position) based on assessed communication conditions. This parameter change allows the system to achieve processing efficiency improvements when needed while avoiding unnecessary overhead increases, as the formatting is adjusted to match the actual communication requirements
3Device complexity
If a fixed frame format is used, then system complexity is reduced, but adaptability to different communication types deteriorates
Solution Approach 1:
The patent creates a universal frame formatting mechanism that can serve multiple communication types through a single adaptive system. The transmitter is designed to detect communication type and automatically adjust header formatting accordingly, allowing one system to handle both low data rate (overhead-sensitive) and high data rate (processing-sensitive) communications without requiring separate formatting systems
Solution Approach 2:
Rather than maintaining multiple fixed formats, the invention implements a dynamic formatting system that transitions between different header placement strategies based on communication conditions. This dynamic approach maintains system simplicity while achieving versatility, as the same system adapts its behavior rather than requiring separate dedicated systems for each communication type

AI summary
Methods and apparatus for formatting headers for data packets within a communication frame for use in a wireless communication system are presented. Formatting headers includes determining the size of a wireless communication frame, and formatting the payloads and associated headers within the communication frame according to the determined size. This formatting includes placing headers at the beginning of the frame before the data packets corresponding to the headers to optimize processing of the headers at a receiver. Formatting may also include formatting the headers according to a first format within the frame when the determined frame size is below a predetermined size to optimize the size of the headers, and formatting according to a second format within the frame when the size of the data packet is equal to or greater than the predetermined size to optimize processing for frames having large data packets.
