Counting Active CSI Resources for UE Processing Complexity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies for wireless communication, specifically in NR (New Radio) systems, face challenges in defining and counting active resources for UE processing complexity related to Beam Management CSI (BM-CSI), particularly in determining when a CSI resource is active and handling multiple resources with the same ID, which affects the UE's processing capability.
Innovation Solution
A method for counting active resources in a slot, where an active resource is defined as the number of CSI resources a UE needs to process simultaneously, considering different reference signals like CSI-RS, CSI-IM, and SSB, with specific counting rules and options for periodic, semi-persistent, and aperiodic configurations, and addressing the uniqueness and double counting of resources.

Engineering Contradiction Analysis
1Adaptability or versatility
If multiple CSI resources with the same ID are configured for different purposes (e.g., L1-SINR, L1-RSRP, PathLoss, BFD, CBD, RLM), then the UE processing capability is improved by having more resources available, but the counting rule becomes unclear and may lead to double counting or incorrect assessment of UE processing complexity
Solution Approach 1:
The patent segments the counting of active resources by dividing it into different time-domain cases (Case 1: all resources active in same slot, Case 2: resources active in different slots). This segmentation provides clear, distinct counting rules for each scenario, eliminating the ambiguity of double counting while maintaining adaptability for multiple CSI resource configurations with the same ID used for different purposes such as L1-SINR, L1-RSRP, PathLoss, BFD, CBD, and RLM.
2Adaptability or versatility
If the definition of active resource time domain behavior is not clearly defined, then the system maintains flexibility in resource configuration, but the UE processing complexity assessment becomes inaccurate
Solution Approach 1:
The patent changes the parameter of resource activation timing by defining two distinct cases: Case 1 where all CSI resources are active in the same slot, and Case 2 where CSI resources are active in different slots. This parameter change approach provides clear, accurate counting rules for each time-domain scenario while maintaining flexibility in resource configuration, thereby resolving the contradiction between adaptability and measurement precision.
