Code Block Segmentation Configuration for 5G Transmission Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Next-generation wireless communication networks, such as 5G, face challenges in dynamically configuring codeblock segmentation to optimize transmission reliability and efficiency, particularly due to varying interference and signal-to-noise ratios, which affect latency and throughput.
Innovation Solution
A base station dynamically configures codeblock segmentation rates based on transmission reliability factors like mobile device speed, location, and signal-to-interference-plus-noise ratios, using multiple input multiple output (MIMO) antennas and prioritizing emergency transmissions, to segment transport blocks into optimal codeblock segments for efficient retransmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If codeblock segmentation is used to improve transmission reliability, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent divides a transport block into multiple codeblock groups, each containing one or more codeblocks. This segmentation allows the system to manage complexity by organizing data into structured units while maintaining transmission reliability through selective retransmission of only failed codeblock groups rather than entire transport blocks.
Solution Approach 2:
The patent dynamically adjusts the codeblock group configuration parameters, including the number of codeblocks per group and the size of each codeblock, based on transmission conditions such as signal-to-noise ratio and interference levels. This allows optimization of reliability while controlling complexity by adapting to channel conditions.
2Productivity
If codeblock segmentation rate is increased to improve throughput, then throughput is improved, but latency increases
Solution Approach 1:
The patent employs dynamic configuration of codeblock segmentation rates based on real-time transmission reliability factors such as mobile device speed, location, and signal-to-interference-plus-noise ratios. The base station adjusts the segmentation rate adaptively, increasing segmentation for high-throughput scenarios and reducing it when latency is critical, thus balancing throughput and latency requirements.
3Adaptability or versatility
If dynamic configuration of segmentation rates is implemented to adapt to varying interference, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the base station determines transmission reliability factors (mobile device speed, location, signal-to-interference-plus-noise ratios) and uses this information to dynamically configure codeblock segmentation rates. The system continuously monitors channel conditions and adjusts segmentation parameters accordingly, enabling adaptability while managing complexity through centralized control at the base station.

AI summary
Various embodiments disclosed herein provide for a codeblock segmentation configuration system. A base station can configure the segmentation rate or segment size, which can control the number of codeblock segments a transport block is segmented into, based on the transmission reliability and predicted interference to a mobile device. An increased number of segments can improve throughput and efficiency when interference is low and signal to noise ratios are high, but can increase latency when interference is high and signal to noise is low. The base station can determine or predict transmission reliability based on the speed of mobile devices, the location and/or distance to the mobile device, as well as the long term signal to noise ratios.
