5G FEC Coding Scheme Selection via RRC Connection Request
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G wireless systems, existing technologies lack an efficient method to dynamically select the appropriate Forward Error Correction (FEC) coding scheme for signaling and control messages based on the capabilities of end devices, leading to suboptimal error correction and potential performance issues due to varying channel conditions.
Innovation Solution
A coding selection service is implemented where 5G networks determine the FEC coding scheme by analyzing data from end devices in connection request messages, allowing for the selection of Turbo, LDPC, or other coding schemes based on channel conditions, enabling adaptive coding for improved communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed FEC coding scheme is used for all end devices, then device complexity is reduced and ease of operation is improved, but communication reliability deteriorates due to varying channel conditions and device capabilities
Solution Approach 1:
The patent applies preliminary action by having end devices pre-determine and report their FEC coding capabilities to the network before actual data transmission. The network stores this capability information and uses it to select appropriate coding schemes in advance, avoiding real-time decision complexity during transmission while ensuring reliable communication matched to device capabilities and channel conditions
2Reliability
If adaptive FEC coding scheme selection is implemented based on channel conditions, then communication reliability is improved, but device complexity and system complexity increase due to the need for capability tracking and dynamic selection
Solution Approach 1:
The patent applies self-service by enabling end devices to autonomously determine their own FEC coding capabilities and report them to the network. Each device independently assesses its own capabilities without requiring complex centralized analysis, reducing overall system complexity while maintaining adaptive error correction performance matched to actual device and channel conditions
3Adaptability or versatility
If multiple FEC coding schemes are supported and dynamically selected, then adaptability to different channel conditions is improved, but ease of operation deteriorates due to the complexity of managing multiple coding options
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the FEC coding scheme parameter based on channel conditions and device capabilities. The system changes the coding parameter (Turbo, LDPC, or other schemes) according to measured channel quality and reported device capabilities, enabling adaptability to varying conditions while maintaining operational simplicity through automated parameter selection rather than manual configuration
