Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems, particularly in the context of 5G, face challenges in accurately determining radar cross section (RCS) information for target objects, which affects sensing performance and target detection criteria.
Innovation Solution
A sensing node receives assistance data including RCS information from a sensing entity and uses this data to obtain target attributes, or performs sensing measurements to determine RCS information, which it then transmits to the sensing entity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless communication systems perform sensing measurements to determine RCS information, then sensing performance is improved, but measurement precision and detection accuracy are insufficient for reliable target detection
Solution Approach 1:
The patent introduces assistance data as an intermediary element that bridges the gap between sensing measurements and target detection. This assistance data includes RCS information, target object attributes, and detection criteria that mediate the relationship between raw sensing measurements and accurate target detection, enabling reliable detection without requiring perfect measurement precision alone
Solution Approach 2:
The patent applies preliminary action by providing assistance data before the actual target detection process. The assistance data includes pre-determined RCS information and detection criteria that are prepared in advance, allowing the sensing node to make more accurate detection decisions when performing actual sensing measurements, thus improving overall reliability without requiring perfect real-time measurement precision
2Measurement precision
If sensing nodes perform comprehensive sensing measurements to improve detection accuracy, then target detection accuracy is improved, but device complexity and processing requirements increase
Solution Approach 1:
The assistance data acts as an intermediary that simplifies the sensing node's processing requirements. Instead of requiring the sensing node to perform complex comprehensive measurements, the node can use the provided assistance data containing RCS information and detection criteria to achieve accurate target detection with simpler processing
Solution Approach 2:
The sensing node uses the assistance data to serve its own detection needs independently. The assistance data provides the necessary RCS information and detection criteria that enable the sensing node to autonomously perform accurate detection without requiring complex measurement capabilities or extensive processing power
3Productivity
If the sensing node uses assistance data with RCS information to improve detection, then detection efficiency is improved, but loss of information about target object characteristics occurs
Solution Approach 1:
The assistance data serves as an intermediary that efficiently conveys essential target object characteristics without requiring the sensing node to process all possible information. It selectively provides the most relevant RCS information and detection criteria, improving detection efficiency while maintaining necessary information about target characteristics through the mediation of this structured assistance data

AI summary
In some aspects, a sensing node may receive assistance data for a sensing session from a sensing entity, where the assistance data includes at least first radar cross section (RCS) information associated with a first target object, and where the first RCS information may include one or more first parameters indicating a first RCS associated with the first target object. The sensing node may obtain at least one or more first target attributes of the first target object based at least on the first RCS information.
