UE SRS Capability Reporting for Flexible Resource Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing communication technologies, the flexible scheduling of User Equipment (UE) by the base station is restricted due to the inability to accurately configure SRS resources based on the varying capabilities of multiple panels in the UE.
Innovation Solution
The proposed solution involves an information transmission method where the UE receives indication information from the network side device and transmits capability information indicating its current SRS transmission capability. This capability information includes details such as the maximum number of SRS resource sets, SRS resources, and SRS resources in each set, allowing the network side device to configure SRS resources more accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the base station configures SRS resources based on the minimum capability report value M, then the configuration is compatible with all panels, but the flexible scheduling of the UE is restricted when the UE switches to a better panel
Solution Approach 1:
The patent implements dynamic capability reporting where the UE reports its current panel capability information to the base station in real-time or periodically. When the UE switches between panels, it updates the capability report to reflect the current panel's M value. This allows the base station to dynamically adjust SRS resource configurations to match the current panel's capabilities, resolving the contradiction between maintaining compatibility and enabling flexible scheduling.
Solution Approach 2:
The patent introduces a feedback mechanism where the UE continuously reports its panel capability information (including the current M value) to the base station. The base station uses this feedback to adjust its SRS resource configuration decisions. This closed-loop feedback system enables the base station to adapt configurations to the current panel state, improving scheduling flexibility while maintaining compatibility.
2Reliability
If the UE reports capability information based on the minimum M value across all panels, then the base station can configure resources for all panels, but the configuration does not match the actual capability of the currently activated panel
Solution Approach 1:
The patent applies local quality by having the UE report capability information specific to the currently activated panel rather than a global minimum across all panels. Each panel may have different capability characteristics, and the reporting mechanism focuses on the local (current panel) properties. This allows the base station to configure SRS resources that precisely match the current panel's capabilities, improving both accuracy and compatibility.
Solution Approach 2:
The patent implements parameter changes by dynamically updating the capability report parameters (particularly the M value) based on which panel is currently activated. When the UE switches panels, the reported capability parameters change to reflect the new panel's characteristics. This enables the base station to adjust configurations with precise parameter matching for the current panel while maintaining overall system compatibility.
