Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wireless communication standards lack specific procedures for time-domain channel property (TDCP) measurement and reporting, including time restrictions and CPU occupation, which are crucial for high-speed railway and expressway scenarios.
Innovation Solution
The proposed methods define time restrictions and CPU occupation schemes for TDCP reporting by specifying the selection of Tracking Reference Signal (TRS) occasions and their measurement intervals, based on CSI report settings and reference resources, to ensure accurate and efficient TDCP reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If TDCP measurement and reporting procedures are established, then measurement precision and communication efficiency are improved, but device complexity and protocol overhead increase
Solution Approach 1:
The patent segments the TDCP measurement process into distinct components: TRS occasion selection, channel property measurement, and report generation. This segmentation allows for manageable complexity in each component while achieving precise overall measurement. The TRS occasions are selected based on specific criteria (periodic or aperiodic) which divides the measurement task into recognizable patterns.
Solution Approach 2:
The patent implements preliminary action by pre-configuring TRS occasions and measurement parameters before actual TDCP measurement. The network device configures TRS resources and the wireless device prepares measurement settings in advance, so that when measurement is needed, the process can proceed efficiently without complex real-time decisions.
2Measurement precision
If multiple TRS occasions are used for measurement, then measurement precision is improved, but CPU occupation time increases
Solution Approach 1:
The patent employs periodic action through the use of periodic TRS occasions for TDCP measurement. Instead of continuously measuring, the system performs measurements at predetermined periodic intervals, which reduces CPU occupation time while maintaining measurement precision through consistent periodic sampling. The periodicity is configured based on channel variation characteristics.
Solution Approach 2:
The patent applies dynamics by allowing flexible configuration of TRS occasion timing and measurement parameters based on actual channel conditions. The system can adjust measurement frequency and TRS selection dynamically to balance between measurement precision and CPU time consumption, rather than using fixed rigid schedules.
3Productivity
If time restriction for channel measurement is implemented, then productivity is improved, but measurement precision may deteriorate
Solution Approach 1:
The patent applies local quality by implementing time restriction specifically for certain measurement components while maintaining broader measurement capabilities. The time restriction is applied locally to TRS occasion selection and report generation timing, allowing efficient processing for critical measurements while preserving accuracy for essential channel property characterization.
Solution Approach 2:
The patent uses parameter changes to balance productivity and measurement precision. By adjusting measurement parameters such as TRS occasion spacing, measurement duration, and reporting timing, the system can optimize the trade-off between processing efficiency and measurement accuracy based on specific operational requirements.
