CSI Processing Unit Counting for Doppler Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently processing channel state information (CSI) reports, particularly when these reports include Doppler shift measurements, per-path Doppler measurements, or per-beam-per-path Doppler measurements, due to limitations in determining the required number of CSI processing units (CPUs).
Innovation Solution
A method and apparatus for a user equipment (UE) to obtain a CSI report associated with a multi-symbol downlink reference signal, which indicates a report quantity related to Doppler shift or per-path/per-beam Doppler measurements, and to count the necessary number of CPUs for processing the CSI report based on the report quantity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the system processes comprehensive CSI reports including Doppler shift measurements, per-path Doppler measurements, or per-beam-per-path Doppler measurements, then the measurement precision and reliability are improved, but the device complexity and CPU resource requirements increase
Solution Approach 1:
The patent segments the CSI processing task by introducing a CSI processing unit counter that tracks and manages CPU resource allocation specifically for Doppler measurement processing. This segmentation allows the system to handle complex CSI reports with detailed Doppler measurements (shift, per-path, per-beam-per-path) while maintaining controlled CPU resource usage through structured unit counting and management.
2Reliability
If the system allocates more CPU resources for processing detailed CSI reports, then the processing capability and reliability are improved, but the loss of time for resource allocation and management increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring and tracking CSI processing units through a dedicated counter mechanism. The system prepares and manages the allocation of CPU resources for Doppler measurements in advance, rather than allocating resources ad-hoc when processing is needed. This preliminary structuring of resource management reduces the time loss associated with dynamic resource allocation while ensuring reliable processing capacity is available.
3Ease of operation
If the system uses standardized CPU allocation for CSI processing, then the ease of operation is improved, but the adaptability to different measurement types (Doppler shift, per-path, per-beam-per-path) decreases
Solution Approach 1:
The patent applies dynamics by creating an adaptive CSI processing unit counter that can dynamically adjust to different measurement types. The counter mechanism is designed to accommodate varying levels of measurement detail (from basic Doppler shift to comprehensive per-beam-per-path measurements) while maintaining a standardized operational framework. This dynamic structure allows the system to easily operate with different measurement configurations without sacrificing adaptability.
