Polar Code Block Segmentation for 5G Decoding Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently encoding and decoding polar codes, particularly in determining the number of segmentations and deciding when to perform segmentation, which affects decoding performance in 5G communication systems.
Innovation Solution
A method and apparatus for determining the number of segmentations in a wireless communication system by generating a bit sequence and performing code block segmentation based on the number of bits, allowing for stable and efficient encoding and decoding using polar codes, including the use of a controller to manage segmentation and encoding/decoding processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If code block segmentation is performed for polar code encoding, then decoding performance is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the bit sequence into multiple code blocks based on the total number of bits. When the bit sequence length exceeds a threshold, it is segmented into multiple blocks that are encoded and decoded separately, improving decoding performance while managing complexity through controlled division
Solution Approach 2:
The patent changes the parameter of code block size by dynamically determining the number of segments based on the total bit sequence length. The system adjusts the segmentation parameter adaptively, using different numbers of segments (e.g., 2, 4, or more) depending on the data size, thereby optimizing the balance between decoding performance and processing complexity
2Productivity
If the number of segmentations is increased, then encoding and decoding efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic segmentation where the number of code blocks is not fixed but determined adaptively based on the total number of bits in the bit sequence. The system dynamically selects the segmentation level (e.g., dividing into 2, 4, or more blocks) according to the data size, allowing encoding and decoding efficiency to be optimized for different traffic conditions without manual configuration
Solution Approach 2:
The patent performs preliminary determination of the number of segments before actual encoding begins. The controller calculates the appropriate number of code blocks based on the bit sequence length and prepares the segmentation structure in advance, which streamlines the subsequent encoding and decoding processes by eliminating runtime decision-making complexity
