FEC Delivery Block Header Fragmentation for Mobile Radio Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, the transmission and reception of Forward Error Correction (FEC) packets result in significant signaling overhead due to header information, leading to increased data loss and reduced radio resource efficiency.
Innovation Solution
The method involves fragmenting FEC delivery block-oriented header information into multiple payload headers within FEC packets, allowing only packet-oriented header information to be included in each payload, thereby reducing the need for transmitting AL-FEC signaling information in every FEC packet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complete header information including AL-FEC signaling is included in every FEC packet, then packet integrity and error correction capability are improved, but signaling overhead increases and radio resource efficiency deteriorates
Solution Approach 1:
The header information is segmented into two types: packet-oriented header information (included in every packet) and FEC delivery block-oriented header information (included only in specific packets). This segmentation allows the system to maintain error correction capability while reducing redundant signaling overhead in each packet transmission.
Solution Approach 2:
Instead of including complete header information in every FEC packet, the invention applies partial action by including only necessary packet-oriented header information in each packet, and uses selective transmission of FEC delivery block-oriented header information in specific packets within the delivery block, thereby reducing overall signaling overhead while maintaining reliability.
2Reliability
If complete header information is transmitted in every FEC packet, then packet integrity is improved, but transmission delay and signaling overhead increase
Solution Approach 1:
Header information is divided into packet-oriented components (essential for each packet) and FEC delivery block-oriented components (shared across multiple packets). This segmentation reduces the amount of data that needs to be transmitted in every packet, thereby reducing transmission delay while maintaining packet integrity through selective inclusion of necessary information.
Solution Approach 2:
Multiple packets share common FEC delivery block-oriented header information, which is transmitted once and applied to the entire delivery block. This merging approach eliminates redundant transmissions of the same information across multiple packets, reducing overall transmission delay while preserving packet integrity.
3Reliability
If AL-FEC signaling information is transmitted in every FEC packet, then error correction reliability is improved, but radio resource efficiency and bandwidth utilization deteriorate
Solution Approach 1:
AL-FEC signaling information is segmented into packet-oriented signaling (included in every packet for immediate error correction needs) and FEC delivery block-oriented signaling (included selectively in specific packets). This segmentation maintains error correction reliability by ensuring necessary signaling is present while improving radio resource efficiency by eliminating redundant signaling transmissions.
Solution Approach 2:
The invention applies partial action by transmitting AL-FEC signaling information only where necessary - packet-oriented signaling in every packet and FEC delivery block-oriented signaling in selected packets - rather than transmitting complete signaling information in every packet. This approach maintains error correction reliability while optimizing radio resource efficiency and bandwidth utilization.

AI summary
An apparatus and method for transmitting/receiving a Forward Error Correction (FEC) packet in a mobile communication system are provided. In the FEC packet transmission method, an FEC packet transmission apparatus transmits an FEC delivery block to an FEC packet reception apparatus. The FEC delivery block includes N payloads. Each of the N payloads includes a payload header. Each payload header included in each of C payloads among the N payloads includes packet oriented header information and an FEC delivery block oriented header information fragment. The packet oriented header information is applied to a related payload, and the FEC delivery block oriented header information fragment is generated by fragmenting FEC delivery block oriented header information applied to the N payloads.
