Engineering Contradiction Analysis
1Measurement precision
If additional technical equipment and air interface resources are used for radiofrequency sensing, then sensing information quality improves, but resource consumption and system complexity increase
Solution Approach 1:
The patent enables existing communication network components (base stations, air interface resources) to perform dual functions: traditional communication tasks and radiofrequency sensing. By using the same infrastructure for both purposes, the system obtains sensing information without adding dedicated sensing equipment, thus improving measurement precision while avoiding increased device complexity
Solution Approach 2:
The communication network's existing signals and resources are utilized to provide sensing capabilities. The system serves itself by using its own transmission resources and infrastructure to generate the sensing measurements, eliminating the need for external or additional specialized equipment
2Measurement precision
If additional technical equipment and air interface resources are used for radiofrequency sensing, then sensing information quality improves, but resource consumption increases
Solution Approach 1:
The patent makes existing air interface resources serve multiple purposes simultaneously - communication and sensing. By reusing the same frequency resources, time slots, and base station transmissions for both functions, the system improves sensing quality without proportionally increasing resource consumption, as the same resources are being utilized more efficiently
Solution Approach 2:
The system uses its own existing transmission resources to provide sensing capabilities. Rather than allocating separate dedicated resources for sensing, the network leverages its own communication signals and infrastructure, thereby improving measurement precision while minimizing additional resource consumption
