Innovation Solution
A method and device for determining spatial parameter information by prioritizing transmission signals based on configuration information, using Transmission Configuration Indicator (TCI) code points or Control Resource Set (CORESET), and ensuring a time interval threshold is met for effective spatial parameter determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple transmission signals with different spatial parameters are transmitted in the same symbol, then the throughput and frequency spectrum efficiency are improved, but the difficulty of determining spatial parameters increases
Solution Approach 1:
The patent changes the parameter of spatial parameter determination by introducing priority information and time interval thresholds. When multiple transmission signals occupy the same time-frequency resource, the system determines spatial parameters based on priority relationships and timing conditions rather than attempting to handle all signals equally, thus resolving the contradiction between maintaining high throughput and simplifying parameter determination
Solution Approach 2:
The patent applies local quality by differentiating spatial parameter determination based on specific conditions: whether the time interval meets the threshold, whether priority information indicates a specific signal should be used. This allows different determination methods to be applied locally to different signal scenarios, improving overall system efficiency while managing complexity
2Reliability
If priority information and time interval thresholds are introduced for spatial parameter determination, then the reliability of parameter selection is improved, but the device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring priority information and time interval thresholds before transmission occurs. The UE and network equipment are configured with these parameters in advance, so that during actual transmission, the spatial parameter determination can be performed efficiently by comparing against pre-set criteria rather than making complex real-time decisions, thus improving reliability without proportionally increasing complexity
