Random Access Reporting for RA Configuration Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-organizing network (SON) solutions lack comprehensive reporting of random access (RA) information, hindering effective optimization of RA configurations, particularly in scenarios involving RA partitioning, Message 3 repetition, synchronization signal block issues, listen before talk failures, secondary cell group activations, beam failure recoveries, and timing advance reports.
Innovation Solution
A method and device for enhanced RA information reporting, including details on RA partition, Message 3 repetition, synchronization signal block issues, listen before talk failures, secondary cell group activations, beam failure recoveries, and timing advance reports, allowing terminal devices to store and transmit this information to network devices for optimized RA configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If comprehensive RA information reporting is implemented, then RA performance optimization is improved, but device complexity and signaling overhead increase
Solution Approach 1:
The patent segments RA information reporting into multiple distinct information elements (IEs), each covering specific RA aspects such as RA partition, Message 3 repetition, synchronization signal block issues, listen before talk failures, secondary cell group activations, beam failure recoveries, and timing advance reports. This segmentation allows the network to selectively request and process only the relevant information needed for specific optimization scenarios, reducing overall reporting complexity while maintaining comprehensive optimization capability.
2Adaptability or versatility
If multiple RA information elements are reported, then network optimization capability is improved, but signaling overhead increases
Solution Approach 1:
The patent implements partial reporting by allowing the network to selectively request specific RA information elements based on current optimization needs rather than requiring complete reporting of all RA parameters. The network can request only the subset of information relevant to the specific optimization scenario, reducing signaling overhead while maintaining adaptability for comprehensive optimization when needed.

AI summary
Embodiments of the present disclosure relate to methods, devices and computer readable media of communication. A terminal device stores and transmits information of a RA procedure to a network device. The information of the RA procedure comprises at least one of the following: information regarding RA partition, information regarding Msg3 repetition, information regarding a TA report, or information regarding the RA procedure triggered due to none of SSBs associated with a CG resource for SDT has RSRP above threshold power, or due to consistent LBT failure recovery, or due to SCG activation, or due to BFR for two sets of BFD-RSs. In this way, a RA configuration may be optimized.
