Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If beam indication information for sensing signals is determined using the same method as communication signals, then the device complexity is reduced, but the measurement precision of beam direction towards sensing targets deteriorates due to changing relative locations in mobile scenarios
Solution Approach 1:
The patent segments the beam indication information into two distinct parts: communication signal beam indication and sensing signal beam indication. This segmentation allows each type of signal to have its own dedicated beam determination method, enabling the sensing beam to be independently optimized for accuracy while the communication beam follows existing protocols, thus resolving the contradiction between device complexity and measurement precision.
Solution Approach 2:
The patent applies local quality by making the beam indication information specific to the signal type. The sensing beam indication information is locally optimized to account for changing relative locations between transmitting end, receiving end, and sensing targets, while communication beam indication maintains its established structure. This localized optimization ensures high measurement precision for sensing without unnecessarily complicating the overall system.
2Measurement precision
If separate beam indication information is used for sensing signals, then the measurement precision of beam direction is improved, but the device complexity increases due to additional information processing
Solution Approach 1:
The patent merges the determination of beam indication information for sensing signals with the existing beam management framework. By integrating sensing beam indication into the overall beam management process rather than creating a completely separate system, the patent achieves high measurement precision while avoiding excessive device complexity. The sensing beam indication is processed alongside communication beam indication using unified management procedures.
Solution Approach 2:
The patent designs the beam indication information structure to serve multiple functions simultaneously. The same beam indication mechanism is used for both communication signals and sensing signals, allowing the system to maintain high measurement precision for sensing while reusing existing processing infrastructure, thereby minimizing the increase in device complexity.
3Measurement precision
If beams are adjusted frequently to track changing relative locations in mobile scenarios, then the measurement precision is maintained, but the loss of time for beam adjustment increases
Solution Approach 1:
The patent applies preliminary action by determining the beam indication information for sensing signals in advance based on predicted or current location information. The transmitting end or receiving end can calculate appropriate sensing beams before actual sensing operations are needed, considering the mobile nature of the scenario. This preliminary determination reduces the time required for real-time beam adjustments while maintaining measurement precision.
Solution Approach 2:
The patent implements dynamics by making the beam indication information adaptive to changing relative locations. The system dynamically adjusts beam directions based on updated location information between transmitting end, receiving end, and sensing targets. This dynamic adjustment mechanism maintains high measurement precision in mobile scenarios while optimizing the timing and frequency of beam changes to minimize time loss.
