Solution Overview

Problem

In 5G new radio systems, the Ethernet frame's packet headers require more bytes than the data part, leading to redundant transmission and inefficient use of air interface resources due to the lack of header compression solutions for Ethernet frames.

Innovation Solution

A method for header compression of Ethernet frames is introduced, where a device determines the need for compression based on configuration information and identifies a header compression object within the Ethernet frame, performing compression on this object to reduce redundant header transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If header compression is not performed on Ethernet frames, then the complete header information is transmitted ensuring reliability, but air interface resources are wasted and data transmission efficiency is reduced

Engineering Contradiction:
Improvedata transmission efficiencyVSAvoidair interface resource waste
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The Ethernet frame header is segmented into multiple parts: static parts (destination address, source address) that remain unchanged, and dynamic parts (length/type, VLAN tags, priority) that may vary. Only the necessary dynamic parts are transmitted in full, while static parts are inferred by the receiver, reducing redundant transmission.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the transmission parameter of header information by transmitting only essential fields in full and using compression indicators to signal the receiver about the frame structure. Configuration information and specific information parameters are used to control the compression level and mode, adapting to different transmission scenarios.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If header compression is performed on Ethernet frames, then air interface resources are saved and transmission efficiency is improved, but the device complexity increases due to compression algorithms

Engineering Contradiction:
Improvedata transmission efficiencyVSAvoidcompression algorithm complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent extracts only the essential and variable parts of the Ethernet header for transmission (such as length/type fields, VLAN information when needed), while excluding static information that can be inferred. This extraction approach simplifies the compression mechanism compared to compressing the entire header.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The receiver device is equipped with the ability to self-determine the Ethernet frame structure using configuration information and specific information from the compressed transmission. The receiver can infer static header parts and reconstruct the complete frame without requiring the transmitter to send all original header data, reducing transmission overhead with minimal added complexity.

Inventive Principle:
Principle #25Self-service
