Random Access Parameter Reporting for Two-Step and Four-Step Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for reporting random access procedures are not optimized for the two-step random access procedure introduced in Rel-16, leading to poor parameter configuration adaptation.
Innovation Solution
A method and device for reporting a random access parameter list that includes both two-step and four-step random access parameters, allowing the network device to request and receive these lists from the terminal device, enabling adaptive optimization of two-step random access parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing random access reporting methods are used, then the reporting process is simple, but the parameter configuration cannot be adaptively optimized for two-step random access
Solution Approach 1:
The patent segments the random access parameter list into distinct two-step random access parameters and four-step random access parameters. This segmentation allows the system to selectively report and optimize parameters based on the specific random access procedure being used, thereby improving adaptability without unnecessarily increasing complexity for procedures that don't require the new parameters.
Solution Approach 2:
The patent introduces dynamic parameter configuration where the terminal device can adaptively select and report different parameter sets based on the random access procedure type. The network device dynamically requests specific parameter lists (two-step, four-step, or both) based on current network conditions and requirements, enabling flexible optimization rather than static configuration.
2Manufacturing precision
If two-step random access parameters are reported separately, then optimization is improved, but signaling overhead increases
Solution Approach 1:
The patent merges the reporting mechanism for two-step and four-step random access parameters into a unified parameter list structure. This allows both types of parameters to be reported together in a single signaling message rather than requiring separate reporting procedures, thereby reducing signaling overhead while maintaining the ability to precisely optimize each parameter type.
Solution Approach 2:
The patent creates a universal random access parameter list structure that can accommodate both two-step and four-step random access parameters. This multi-functional structure enables the same reporting mechanism to serve multiple purposes - optimizing precision for either procedure type or both simultaneously, depending on network requirements, without requiring separate specialized reporting paths.
