CSI Processing Unit Occupancy for L1-SINR Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in LTE and NR technologies, face challenges in efficiently determining and managing the number of channel state information (CSI) processing units required for layer 1 signal to interference plus noise ratio (L1-SINR) reporting, which affects the accuracy and resource allocation in wireless communication networks.
Innovation Solution
The method involves receiving a CSI reporting configuration that indicates the inclusion of L1-SINR in the CSI report and determining the number of CSI processing units (CPUs) occupied for processing this report, which can be set based on various parameters such as 'cri-SINR', 'ssb-Index-SINR', or equal to the number of CPUs occupied for processing a reference signal received power parameter, allowing for selective updating of the CSI report based on available CPU resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of CSI processing units is increased to improve L1-SINR reporting accuracy, then the measurement precision is improved, but the device complexity and computational overhead increase
Solution Approach 1:
The patent applies partial action by determining CPU occupancy only when L1-SINR reporting is actually configured and needed, rather than always allocating maximum CPU resources. The UE selectively updates CSI reports based on available CPU resources, using only the necessary computational capacity required for L1-SINR calculations when the reporting configuration indicates its inclusion.
Solution Approach 2:
The patent implements dynamic resource allocation by allowing the number of CPUs occupied for CSI processing to vary based on the L1-SINR reporting configuration and available CPU resources. The system adapts the CPU occupancy determination dynamically according to the specific reporting requirements and current resource availability, rather than using a fixed allocation scheme.
2Measurement precision
If CPU resources are allocated for L1-SINR reporting, then the reporting accuracy is improved, but the productivity of other processing tasks decreases due to resource consumption
Solution Approach 1:
The patent applies partial action by allocating CPU resources specifically and only when L1-SINR reporting is configured. The UE determines CPU occupancy selectively based on the reporting configuration, using resources partially and only when necessary for L1-SINR calculations, rather than continuously consuming CPU resources for CSI processing.
Solution Approach 2:
The patent changes the parameter of CPU occupancy based on the L1-SINR reporting configuration. When L1-SINR reporting is configured, the CPU occupancy parameter is adjusted to reflect the additional computational requirements. This parameter change allows the system to adapt resource allocation dynamically, balancing L1-SINR reporting accuracy with overall processing productivity.
3Loss of time
If selective updating of CSI reports is implemented based on CPU resources, then the loss of time for unnecessary processing is reduced, but the ease of operation increases due to resource management complexity
Solution Approach 1:
The patent applies preliminary action by determining CPU occupancy in advance based on the L1-SINR reporting configuration before actual CSI processing occurs. The UE evaluates the reporting configuration and determines the required CPU resources beforehand, allowing selective updating of CSI reports based on pre-assessed resource availability, thus avoiding unnecessary processing time loss.
Solution Approach 2:
The patent implements feedback by using the determined CPU occupancy information to guide subsequent CSI report updating decisions. The system monitors CPU resource availability and adjusts CSI processing accordingly, creating a feedback loop where resource status informs processing decisions, optimizing the balance between time efficiency and operational complexity.
