Position Configuration Method for Frequency Shift Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing mobile communication systems, an additional frequency shift introduces a position shift that cannot be accurately indicated using existing position numbers, leading to inconsistent understanding between transmitting and receiving parties and disrupting normal signal and communication processes.
Innovation Solution
A position configuration method is introduced, where position configuration information including position shift information or position indication information is determined, allowing for the accurate determination of a target position. This method can directly determine specific cases of position shifts or indicate final positions after shifts, ensuring accurate positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If existing position numbers (NR-ARFCN, E-ARFCN) are used to indicate frequency domain positions, then the system maintains simplicity in position indication, but the position accuracy deteriorates when additional frequency shifts are introduced
Solution Approach 1:
The position indication is segmented into two parts: a base position number (NR-ARFCN or E-ARFCN) and a position shift value. The base position number provides the coarse frequency domain position, while the position shift value provides the fine adjustment. This segmentation allows the system to maintain simplicity in the base indication mechanism while achieving high precision through the additional shift parameter.
2Measurement precision
If position shift information is added to achieve accurate position indication after frequency shift, then the position accuracy improves, but the information complexity increases
Solution Approach 1:
The position indication transitions from a one-dimensional position number to a two-dimensional representation by adding the position shift dimension. The base position number provides the primary dimension, while the position shift provides the secondary dimension. This dimensional expansion enables accurate position indication without requiring a complete redesign of the position configuration system.
3Measurement precision
If a new position indication method is introduced to handle frequency shifts, then the position accuracy improves, but the system complexity increases
Solution Approach 1:
The position shift information is pre-calculated and configured before the actual position determination process. The base position number and position shift value are prepared in advance, allowing the terminal device to simply add them together to obtain the final target position. This preliminary preparation simplifies the execution process while achieving high accuracy.
