Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple antenna panels are used for RF sensing, then RF sensing accuracy is improved, but device complexity increases
Solution Approach 1:
The antenna system is segmented into multiple independent antenna panels, each capable of performing RF sensing operations independently. The patent divides the antenna array into separate panels that can be individually configured and controlled, allowing parallel sensing operations while maintaining manageable complexity through modular architecture.
Solution Approach 2:
The patent introduces dynamic configuration capabilities where the network can dynamically select which antenna panels to activate based on sensing requirements. The system can switch between different antenna panel configurations in real-time, enabling flexible adaptation to various sensing scenarios without requiring all panels to be always active, thus reducing overall system complexity.
2Productivity
If each antenna panel performs independent sensing operations, then RF sensing performance is improved, but configuration complexity increases
Solution Approach 1:
Each antenna panel is designed with universal functionality to perform the same basic RF sensing operations independently. The patent ensures that all antenna panels have identical sensing capabilities, allowing them to be interchangeably configured and controlled. This universality simplifies configuration processes while enabling parallel independent operations that improve overall sensing productivity.
Solution Approach 2:
The patent employs parameter-based configuration where different antenna panels can be assigned different operational parameters such as timing offsets, frequency allocations, or beamforming configurations. By changing parameters rather than requiring different hardware architectures, the system achieves independent parallel operations while maintaining configuration simplicity through standardized parameter adjustment mechanisms.
3Measurement precision
If multi-panel RF sensing is implemented, then positioning accuracy is improved, but system configuration complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the network receives information about antenna panel capabilities and sensing results, then uses this feedback to optimize configuration decisions. The system can adaptively select which antenna panels to activate based on real-time feedback about positioning requirements and panel performance, simplifying configuration complexity while maintaining high positioning accuracy through intelligent resource allocation.

AI summary
Aspects presented herein may improve radio frequency (RF) sensing accuracy for an RF sensing node by enabling the RF sensing node to perform RF sensing using multiple antenna/antenna panels. In one aspect, a UE transmits, to a sensing entity, an indication of a capability to perform RF sensing using a set of antenna panels. The UE receives, from the sensing entity based on the indication, a configuration to perform an RF sensing operation using a subset of antenna panels in the set of antenna panels, where each antenna panel in the subset of antenna panels is configured to perform a corresponding RF sensing operation for each antenna panel. The UE performs, based on the configuration, the RF sensing operation via each antenna panel in the subset of antenna panels.
