Functional Split Reconfiguration for AI Function Relocation in Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently reconfiguring functional splits between digital units (DUs) and radio units (RUs) to effectively implement artificial intelligence (AI) functions, particularly in 6G communication systems where hardware limitations and environmental constraints impact AI function performance.
Innovation Solution
A method and apparatus that allow for the reconfiguration of functional splits between DUs and RUs by transmitting and receiving functional split reconfiguration messages, enabling the movement of AI functions from RUs to DUs based on reconfiguration information, thereby optimizing AI function performance and addressing hardware constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If AI functions are implemented in RUs, then service continuity is maintained, but hardware limitations and environmental constraints impact AI function performance
Solution Approach 1:
The patent introduces a functional split reconfiguration mechanism that acts as an intermediary between RU and DU, allowing AI functions to be dynamically relocated based on performance requirements while maintaining service continuity through coordinated handover
2Manufacturing precision
If AI functions are relocated from RU to DU, then AI function performance is improved, but system complexity increases
Solution Approach 1:
The patent implements dynamic functional split reconfiguration that allows the system to adaptively move AI functions between RU and DU based on real-time performance requirements, transforming a static architecture into a dynamic one that can optimize performance without permanent complexity
3Manufacturing precision
If functional split reconfiguration is performed, then AI function performance is optimized, but reconfiguration time and signaling overhead increase
Solution Approach 1:
The patent employs preparation phases before actual functional split reconfiguration, where conditions are assessed and resources are pre-allocated, allowing the reconfiguration to execute more quickly when triggered, thus reducing overall reconfiguration time

AI summary
The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). The disclosure relates to a method performed by an radio unit (RU) of a base station in a wireless communication system, particularly, the disclosure may provide a method performed by an RU of a base station in a wireless communication system, comprising preparing for a functional split reconfiguration, receiving a functional split reconfiguration message from a digital unit (DU) of the base station, and reconfiguring a functional split option so that an artificial intelligence (AI) function of the RU is moved to the DU based on split option reconfiguration information included in the functional split reconfiguration message.
