Wireless Data Packet Compression Using UDC Protocol
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current New Radio (NR) systems do not support compression for data packet headers or both headers and data portions, leading to performance inefficiencies in wireless communication.
Innovation Solution
A wireless communication method and device that performs compression or decompression operations on data packets using the uplink data compression (UDC) protocol, along with other protocols like Ethernet frame header compression (EHC) and robust header compression (ROHC), to improve system performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If no compression is performed on data packets in NR system, then transmission reliability is maintained, but transmission efficiency deteriorates due to larger packet sizes occupying more wireless resources
Solution Approach 1:
The patent extracts and identifies specific fields within data packets that are suitable for compression, separating them from the overall packet structure. This allows selective compression of identifiable fields while maintaining the integrity of the complete packet, thereby improving transmission efficiency without compromising reliability.
Solution Approach 2:
The patent changes the parameter representation of data packet fields by encoding them in a compressed format. This parameter transformation reduces the size of specific fields while maintaining their informational content, directly addressing the contradiction between packet size and transmission efficiency.
2Productivity
If compression protocols are implemented, then data packet size is reduced improving transmission efficiency, but system complexity increases
Solution Approach 1:
The patent segments the data packet into identifiable fields and applies compression selectively to specific fields rather than the entire packet. This segmentation approach reduces the complexity of implementing compression protocols while still achieving size reduction in critical areas, balancing transmission efficiency with system complexity.
3Quantity of substance
If header compression is performed using ROHC or EHC protocols, then header size is reduced, but data portion compression is not supported limiting overall compression effectiveness
Solution Approach 1:
The patent creates a universal compression approach that can handle multiple types of data packet fields (headers and data portions) through a single identifiable field compression mechanism. This multi-functional capability extends beyond traditional header-only compression to include data portion compression, enhancing adaptability while maintaining a unified protocol structure.
