CSI Report Priority Determination for L1-SINR Collision Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lack of a defined priority rule for CSI reports carrying Layer 1 Signal to Interference Noise Ratio (L1-SINR) in communication systems leads to collisions and system operation breakdowns when these reports overlap with other CSI reports, as the UE is unsure how to multiplex or drop them.
Innovation Solution
A method and device for determining priority levels of CSI reports, including a processor and memory, which configure the UE to assess and prioritize CSI reports based on their content, allowing for proper multiplexing or dropping when overlaps occur, with specific priority rules defined for L1-SINR reports in relation to other CSI reports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a priority rule for L1-SINR CSI reports is not defined, then the system introduces flexibility in handling new report types, but CSI report collisions cause system operation breakdown
Solution Approach 1:
The patent assigns different priority levels (parameters) to different types of CSI reports. Specifically, it defines that aperiodic CSI reports have higher priority than semi-persistent CSI reports, and semi-persistent CSI reports have higher priority than periodic CSI reports. This parameter-based priority system resolves the contradiction by providing clear operational rules that maintain system reliability while accommodating various report types.
2Productivity
If the UE does not know how to multiplex or drop CSI reports during collision, then the system allows for potential resource utilization flexibility, but the transmission accuracy and system operation become uncertain
Solution Approach 1:
The patent establishes priority rules in advance (before collision occurs) that dictate exactly how the UE should handle overlapping CSI reports. The pre-defined rules specify that higher priority reports should be transmitted while lower priority reports should be dropped or multiplexed accordingly. This preliminary establishment of operational guidelines ensures transmission accuracy is maintained while allowing flexible resource utilization.

AI summary
A method and a device for determining a priority level of a channel state information (CSI) report are provided. The method includes following operations. The UE determines priority levels of at least two CSI reports, the at least two CSI reports include a first CSI report, and the first CSI report carries Layer 1 Signal to Interference Noise Ratio (L1-SINR). The priority levels of the at least two CSI reports are used to multiplex the at least two CSI reports or drop at least a part of the at least two CSI reports in response to that there is an overlapping part in time domain resources of the at least two CSI reports.
