Time-Domain Window Determination for Joint Channel Estimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method for determining time domain windows in joint channel estimation results in uneven distribution, affecting the accuracy of channel estimation due to significant differences in the number of time slots between windows.
Innovation Solution
A method where user equipment (UE) receives indication information from a base station to determine time domain windows, ensuring that the number of time slots in each window is relatively close, thereby achieving even distribution and improving channel estimation accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the existing method for determining time domain windows is used, then the calculation is simple, but the time domain windows are unevenly distributed, affecting channel estimation accuracy
Solution Approach 1:
The patent changes the parameters used in time domain window determination by introducing a first parameter (first number) and a second parameter (second number) that are separately configured. The time domain window is determined based on these parameters rather than using a fixed formula, allowing flexible adjustment to achieve even distribution while maintaining calculation simplicity.
2Measurement precision
If the number of time slots in each time domain window is made equal, then the distribution is even and channel estimation accuracy is improved, but the flexibility to adapt to different scenarios is reduced
Solution Approach 1:
The patent makes the time domain window determination dynamic by using separately configurable first and second parameters. These parameters can be adjusted based on different scenarios such as TDD time slot formats, allowing the system to adapt to various time slot configurations while still achieving even distribution. The dynamic adjustment capability enables the system to handle different numbers of time slots and various communication scenarios flexibly.
