Solution Overview

Problem

The 5G New Radio (NR) system lacks a processing method for compressing Ethernet packets, leading to inefficient use of transmission resources.

Innovation Solution

A method for determining and processing the state of Ethernet packet headers to enable compression and decompression, using states such as non-compression and compression orders, and decompression states like no context and context states, to optimize packet transmission and reduce resource overhead.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If Ethernet packets are transmitted without compression processing, then transmission reliability is maintained, but transmission resources are wasted

Engineering Contradiction:
Improvetransmission resourcesVSAvoidtransmission reliability
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The patent changes the parameter of packet header representation from uncompressed format to compressed format. It introduces state parameters (compression order, non-compression order) and transforms the header data into a more compact form, reducing transmission resource consumption while maintaining the essential information needed for reliable transmission.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent extracts only the essential information from the Ethernet packet header for transmission. By identifying and transmitting only the necessary fields in a compressed format, it removes redundant data while preserving the core functionality needed for reliable packet delivery and reconstruction at the receiving end.

Inventive Principle:
Principle #2Taking out (Extraction)

2Loss of energy

If compression processing is applied to Ethernet packets, then transmission resources are saved, but processing complexity increases

Engineering Contradiction:
Improvetransmission resourcesVSAvoidprocessing complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent introduces dynamic state management for compression processing, with the compression side device and decomposition side device maintaining corresponding states (compression order, non-compression order, context state, no context state). This dynamic state machine approach allows the system to adaptively switch between compression modes based on current conditions, managing complexity through structured state transitions rather than complex algorithms.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The compression and decompression system uses self-contained state information stored at both transmitting and receiving ends. Each side maintains its own context and state, allowing independent operation without requiring complex coordination protocols. The state information itself serves as the mechanism for both compression and decompression operations.

Inventive Principle:
Principle #25Self-service

3Productivity

If state-based compression processing is implemented, then transmission efficiency is improved, but system complexity increases

Engineering Contradiction:
Improvetransmission efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent performs preliminary actions by establishing compression states and context information in advance at both the compression side device and decomposition side device. By pre-configuring the state machine and context storage before actual compression operations, the system prepares the necessary structures ahead of time, enabling efficient compression without adding complexity during the actual transmission process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The state information and context data serve multiple functions simultaneously: they guide the compression process, enable decompression operations, and maintain synchronization between transmitting and receiving ends. This multi-functional use of state information reduces the need for separate mechanisms for each function, thereby improving efficiency without proportionally increasing system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
