Ethernet Frame Transmission via Field Removal in 5G Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In industrial environments, the transmission of Ethernet frames in 5G systems requires significant resource overheads due to the relatively small payload and the need to transmit complete frames.
Innovation Solution
The proposed solution involves removing specified fields from Ethernet frames, such as the preamble, start frame delimiter, frame check sequence, length, padding, and extension fields, and then transmitting the frames with these fields removed. The receiving device adds the specified fields back to the frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complete Ethernet frames are transmitted in 5G system, then transmission reliability is maintained, but resource overheads increase significantly
Solution Approach 1:
The patent extracts and removes specified fields (preamble, start frame delimiter, frame check sequence, length, padding, and extension fields) from Ethernet frames before transmission through the 5G system. This extraction reduces the frame size and resource overheads while maintaining transmission reliability through selective field removal that preserves essential data.
2Loss of energy
If specified fields are removed from Ethernet frames, then resource overheads are reduced, but frame structure complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring both transmitting and receiving devices with knowledge of which fields to remove and add. The transmitting device removes specified fields before transmission, and the receiving device is pre-programmed to add the same fields back after reception, thereby managing frame structure complexity through advance preparation rather than complex real-time processing.
3Productivity
If Ethernet frame size is reduced by removing fields, then transmission efficiency improves, but information completeness may be compromised
Solution Approach 1:
The patent implements discarding and recovering by removing specified fields from Ethernet frames during transmission to improve efficiency, then recovering these fields at the receiving end by adding them back to the frames. This ensures that while transmission is optimized, the complete frame information is restored for further processing, preventing any loss of essential information.
