Random Access Procedure Reporting for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current random access procedures in wireless networks, such as LTE and 5G, face inefficiencies due to limited reporting of random access procedure information, which hinders optimization of RACH parameters and resource allocation, leading to increased RACH failures and preamble transmissions.
Innovation Solution
Implementing a method where user equipment logs and reports detailed random access procedure information for various trigger types, enabling a machine learning algorithm to adjust RACH parameters and resource allocation based on trigger-specific costs, thereby optimizing RACH performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If detailed random access procedure information is logged and reported for multiple trigger types, then optimization accuracy of RACH parameters is improved, but device complexity and signaling overhead increase
Solution Approach 1:
The patent segments random access procedure information by different trigger types (e.g., scheduling request failure, uplink data arrival, downlink data arrival). Each trigger type is logged and reported separately, allowing the base station to optimize RACH parameters specifically for each trigger type rather than using a generic optimization approach. This segmentation enables precise optimization while managing reporting complexity through structured categorization.
2Adaptability or versatility
If trigger-specific random access procedure information is reported, then RACH parameter optimization for specific scenarios is improved, but information processing overhead increases
Solution Approach 1:
The patent applies local quality by providing different levels of random access procedure information for different trigger types based on their specific optimization needs. For example, scheduling request failure scenarios may require detailed information about preamble transmission attempts, while other scenarios may require less detailed reporting. This allows the system to process only the necessary information for each specific scenario, reducing overall processing overhead while maintaining scenario-specific optimization capability.
3Reliability
If comprehensive random access procedure logging is implemented, then RACH failure reduction is improved, but user equipment resource consumption increases
Solution Approach 1:
The patent implements preliminary action by having user equipment log random access procedure information in advance during actual random access operations. The logged information is prepared and stored locally before being reported to the base station in response to requests. This preliminary logging during normal operations allows comprehensive data collection without requiring additional dedicated resources at the moment of reporting, thereby reducing RACH failures while managing UE resource consumption efficiently.
