Adaptive Polar Coding Configuration for 5G Processing Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high computational complexity and long processing time of polar coding in 5G systems lead to increased power consumption and inefficient use of radio resources, particularly due to the fixed application of sequential decoding algorithms.
Innovation Solution
Adaptive polar coding configuration is determined based on the capability of user equipment (UE) and channel state, including parameters such as the number of decoders, code length, decoding algorithms, and list size, to optimize processing time and power consumption.

1Measurement precision
If sequential decoding algorithm is applied for polar coding in 5G systems, then decoding accuracy is improved, but processing time and power consumption increase
Solution Approach 1:
The patent applies dynamics by making the polar coding configuration adaptive rather than fixed. The base station determines configuration parameters (number of decoders, code length, decoding algorithm, list size) dynamically based on UE capability and channel state, allowing the system to switch between different decoding strategies to optimize both accuracy and processing time under varying conditions
Solution Approach 2:
The patent changes parameters of the polar coding configuration including number of decoders, code length, decoding algorithm type, and list size. By adjusting these parameters adaptively based on channel conditions and UE capabilities, the system can balance decoding accuracy with processing time and power consumption requirements

3Device complexity
If fixed polar coding configuration is applied, then system complexity is reduced, but adaptability to different channel conditions deteriorates
Solution Approach 1:
The patent transforms the fixed configuration into a dynamic adaptive configuration. The base station determines polar coding configuration parameters based on real-time UE capability information and channel state, enabling the system to adapt to different channel conditions while maintaining manageable complexity through automated decision-making
Solution Approach 2:
The patent implements feedback mechanisms where the base station receives UE capability information and channel state feedback, then uses this information to determine and adjust polar coding configuration parameters. This closed-loop feedback system enables adaptability without requiring complex manual configuration
