Terminal Uplink Transmission Capability Reporting for Switching Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inconsistent understanding of uplink transmission channel switching behaviors between terminals and network-side devices leads to errors in terminal uplink transmission, as existing reporting methods do not provide clear guidelines for additional UE capabilities.
Innovation Solution
A method and apparatus for reporting terminal capabilities with different granularities, including first and second capabilities indicating support for uplink transmission within specific switching periods and time periods, based on band pairs, bands, and band combinations, to ensure consistent understanding between terminals and network-side devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple UE capabilities are added for UL Tx switching, then the terminal's transmission capability is improved, but the consistency of understanding between terminal and network-side device deteriorates
Solution Approach 1:
The patent segments the capability reporting into multiple independent capability fields (first capability information, second capability information, third capability information) corresponding to different band pairs and switching scenarios. Each capability field independently indicates whether the terminal can perform UL Tx switching for a specific band pair, allowing the network-side device to accurately understand terminal capabilities without ambiguity, thus resolving the contradiction between enhanced adaptability and understanding consistency.
2Measurement precision
If detailed capability information is reported for each band pair, then the accuracy of switching behavior understanding is improved, but the signaling overhead increases
Solution Approach 1:
The patent applies local quality by making the capability reporting granularity match the specific band pair characteristics. Each capability field (first, second, third capability information) is locally optimized to report only the necessary switching capability for its corresponding band pair, avoiding unnecessary signaling for band pairs where switching is not applicable. This ensures high accuracy where needed while minimizing overall signaling overhead.
