Reference Signal Measurement With Terminal Timing Deviation Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In dynamic time division duplex (TDD) scenarios, cross interference between uplink and downlink transmissions in different cells is exacerbated by timing deviations between terminal devices, leading to inaccurate reference signal measurements due to differences in symbol timing.
Innovation Solution
A method and device that determine the timing deviation between terminal devices using indication information, adjusting the timing relationship to ensure accurate measurement of reference signals by synchronizing the reception and transmission times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dynamic TDD configuration is used to adapt to service transmission, then service transmission adaptability is improved, but cross interference between uplink and downlink transmissions in different cells increases
Solution Approach 1:
The patent implements a feedback mechanism where terminal devices measure reference signals and report measurement results to the network side. The network side uses this feedback information to adjust TDD configuration and timing parameters, creating a closed-loop system that adapts to interference conditions dynamically while maintaining service quality.
Solution Approach 2:
The patent introduces dynamic timing adjustment mechanisms where the timing deviation between terminal devices is continuously monitored and adjusted. The system dynamically modifies transmission timing parameters based on real-time interference conditions, allowing the TDD configuration to adapt flexibly to changing network conditions and reduce cross-interference.
2Ease of operation
If timing deviation between terminal devices is not corrected, then measurement simplicity is maintained, but reference signal measurement accuracy deteriorates
Solution Approach 1:
The patent applies preliminary timing correction by having terminal devices obtain indication information about timing deviations before performing reference signal measurements. The timing adjustment is performed in advance, ensuring that when the measurement occurs, the timing deviation has already been corrected, thereby maintaining measurement simplicity while improving accuracy.
Solution Approach 2:
The patent introduces an intermediary mechanism where indication information about timing deviations is exchanged between terminal devices and the network side. This intermediary timing information acts as a mediator that enables accurate reference signal measurements without requiring direct complex synchronization between all terminal devices, thus maintaining operational simplicity while achieving measurement precision.
