5G NR Parameter Configuration for Phase Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of 5G NR technology, ensuring power consistency and phase continuity within a time window for joint channel estimation is challenging, particularly due to the need for precise configuration of parameter information related to the time window and demodulation reference signal (DMRS) bundling size, which existing methods fail to address effectively.
Innovation Solution
A method and apparatus for configuring parameter information, including window size and DMRS bundling size, where the window size is greater than or equal to the DMRS bundling size, to ensure power consistency and phase continuity during joint channel estimation, involving explicit or implicit configuration through signaling messages or resource parameter mapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parameter information is not configured or configured incorrectly, then the system complexity is reduced, but power consistency and phase continuity cannot be ensured
Solution Approach 1:
The network device performs preliminary configuration of parameter information (window size and DMRS bundling size) before joint channel estimation is executed. This advance configuration ensures that the terminal device has the necessary parameters ready to maintain power consistency and phase continuity, resolving the contradiction by preparing the system in advance rather than dealing with complexity during execution.
Solution Approach 2:
The patent introduces specific parameter changes (window size and DMRS bundling size) that the network device configures for the terminal. By changing and controlling these parameters, the system ensures power consistency and phase continuity during joint channel estimation, while the configuration is managed through standardized signaling mechanisms to control complexity.
2Adaptability or versatility
If window size and DMRS bundling size are configured independently without constraints, then the adaptability is improved, but phase continuity may be destroyed
Solution Approach 1:
The patent applies local quality by imposing a specific constraint (window size ≥ DMRS bundling size) on the relationship between parameters. This local constraint ensures that while the system maintains adaptability through configurable parameters, the phase continuity is preserved by ensuring the time window is sufficiently large to contain the DMRS bundling operations without disruption.
Solution Approach 2:
The patent enables dynamic configuration of window size and DMRS bundling size parameters while maintaining the constraint relationship. The network device can adjust these parameters dynamically based on channel conditions and traffic requirements, and the terminal adapts accordingly, ensuring both adaptability and phase continuity through coordinated parameter changes.
