L1-Post Signaling Block Segmentation for Reliable Decoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional broadcasting/communication systems face challenges in efficiently encoding and decoding control information, particularly L1-post signaling information, due to variations in frame content and decoding performance across different parts of the signaling information.
Innovation Solution
A method and apparatus for segmenting and encoding signaling information into coded blocks, where L1 dynamic information is prioritized at the front to improve decoding performance, and the segmentation scheme is adjusted based on the number of coded blocks and input information bits, allowing for efficient transmission and reception of control information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control information is transmitted using conventional encoding methods, then the transmission process is simple, but the decoding performance of control information is insufficient
Solution Approach 1:
The control information is segmented into multiple coded blocks, where each block contains specific control information elements. This segmentation allows the receiver to decode blocks independently and improves overall decoding performance by distributing control information across multiple encoded segments.
Solution Approach 2:
Different encoding parameters and schemes are applied to different coded blocks based on their specific requirements. For example, L1 configurable information and L1 dynamic information may use different code rates or block sizes, optimizing the decoding performance for each type of control information locally rather than using a uniform approach.
2Reliability
If control information is encoded without segmentation, then the encoding process is simpler, but the decoding performance and reliability are reduced
Solution Approach 1:
L1-post signaling information is divided into multiple coded blocks with specific segmentation patterns. Each block is independently encoded, allowing the receiver to recover control information more reliably even if some blocks are corrupted, thereby improving decoding performance.
Solution Approach 2:
The control information is pre-processed and organized into specific coded blocks before transmission, with predetermined segmentation and encoding schemes. This preliminary organization optimizes the structure for reliable decoding at the receiver end.
3Productivity
If conventional transmission methods are used, then the system is easier to implement, but the efficiency of signaling information transmission is reduced
Solution Approach 1:
The transmission apparatus segments control information into coded blocks that can be transmitted efficiently over the channel. This segmentation improves transmission efficiency by allowing parallel processing and optimized resource allocation for different control information elements.
Solution Approach 2:
The system dynamically adjusts encoding parameters such as code rate, block size, and segmentation patterns based on channel conditions and control information types. This parameter optimization improves transmission efficiency while adapting to different operational scenarios.
