5G Random Access Resource Reporting for SSB and CSI-RS Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a more efficient method and device for storing and reporting random access information in next-generation mobile communication systems, particularly related to the reception strength of synchronization signal blocks (SSB) and channel state information-reference signals (CSI-RS) during random access.
Innovation Solution
A method and device that involves storing and reporting first and second resource information related to contention-based and contention-free random access, respectively, by transmitting and receiving messages between a terminal and a base station to efficiently manage random access processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If random access information including SSB and CSI-RS reception strength is reported in detail, then measurement precision is improved, but loss of time increases due to extended reporting duration
Solution Approach 1:
The patent extracts only the essential random access information (SSB and CSI-RS reception strength) from the complete measurement data set, reporting only these critical parameters to the network rather than all available measurement information, thereby reducing reporting time while maintaining measurement precision for the most important metrics
Solution Approach 2:
The patent applies partial action by selectively reporting only certain random access information elements (SSB and CSI-RS reception strength) rather than complete measurement data, achieving sufficient measurement precision for random access decisions without the time cost of reporting all possible measurement parameters
2Reliability
If comprehensive random access information is stored and reported, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent extracts and stores only the critical random access information elements (SSB and CSI-RS reception strength) that are essential for reliable random access operations, eliminating the need to store and process comprehensive measurement data, thereby reducing device complexity while maintaining reliability
Solution Approach 2:
The patent segments the random access information into distinct, manageable components (SSB reception strength and CSI-RS reception strength), storing and processing each separately rather than as a single complex data structure, which reduces device complexity while preserving the reliability needed for accurate random access decisions
