Mixed-Rate Wireless Packet Segmentation and Repetition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, the increasing volume and complexity of information lead to a significant overhead in bandwidth required for physical layer control signals, making it desirable to minimize the number of bits used for signaling and packet acquisition, especially in mixed-rate transmissions.
Innovation Solution
The method involves generating a packet with a plurality of symbols by segmenting an input bit vector into symbol vectors, splitting them into split vectors, and mapping these split vectors using block-level or symbol-level repetition, which are then transmitted, allowing for efficient data transmission with varying data rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the volume and complexity of information communicated wirelessly increases, then the information transmission capability is improved, but the overhead bandwidth required for physical layer control signals increases
Solution Approach 1:
The patent segments the control information into different fields (signal field, data field, training fields) and processes them separately through segmentation and splitting procedures. This allows efficient allocation of bandwidth resources to different control signal components, reducing overall overhead while maintaining complete information transmission capability.
2Productivity
If multiple types of traffic are concurrently sent from an access point to multiple terminals, then the network throughput is improved, but the number of bits required for signaling and packet acquisition increases
Solution Approach 1:
The patent creates a universal packet structure that can handle multiple traffic types concurrently. The segmented and split vector approach allows a single packet format to serve multiple terminals with different traffic requirements, reducing the need for separate signaling for each traffic type while maintaining high network throughput.
3Quantity of substance
If the number of bits used for signaling and packet acquisition is minimized, then the overhead is reduced, but backwards compatibility must be maintained
Solution Approach 1:
The patent applies local quality by maintaining the traditional signal field structure for backwards compatibility while introducing optimized data field segmentation only where needed. This allows legacy devices to interpret the signal field correctly while new devices can utilize the efficient segmented structure for data transmission, reducing overhead without sacrificing compatibility.
