Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently coordinating and integrating communication and radar sensing operations within user equipment (UE), leading to increased complexity, interference, and inefficiency due to separate modules with little coordination, and lack of unified standards.
Innovation Solution
A framework for joint configuration of cellular communication and bistatic object sensing is developed, allowing UEs to transmit or receive sensing signals, with network control over UE configurations, including parameters like waveform, power, and resource allocation, to enable efficient resource use and reduce interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate modules are used for communication and radar sensing, then device functionality is achieved, but device complexity and interference increase
Solution Approach 1:
The patent combines communication and radar sensing operations into a unified framework where a single device performs both functions. The transceiver is configured to alternatively execute communication protocols or radar sensing protocols, merging previously separate modules into one integrated system that reduces complexity while maintaining both functionalities.
Solution Approach 2:
The transceiver is designed as a universal component capable of performing multiple functions - both communication and radar sensing. Through configurable protocol selection, the same hardware infrastructure supports diverse operational modes, eliminating the need for dedicated separate modules and reducing overall device complexity.
2Adaptability or versatility
If separate modules are used for communication and radar sensing, then device functionality is achieved, but interference increases
Solution Approach 1:
The patent implements periodic alternation between communication operations and radar sensing operations. The transceiver switches between these modes in time-divided fashion, ensuring that both functions receive dedicated time slots without simultaneous operation. This periodic action eliminates mutual interference while maintaining both functionalities through temporal separation.
3Productivity
If joint configuration is implemented, then resource efficiency improves, but coordination complexity increases
Solution Approach 1:
The patent introduces dynamic configuration where the transceiver can adaptively switch between communication and radar sensing modes based on real-time conditions. The joint configuration allows flexible resource allocation and protocol selection, optimizing resource efficiency while managing coordination through dynamic rather than static arrangements.

AI summary
Joint configuration of cellular communication and bistatic object sensing involves transmitting, to a UE, a bistatic object sensing configuration. The bistatic object sensing configuration configures the UE to one of receive a sensing signal transmitted by a base station or transmit the sensing signal for reception by the base station. The bistatic object sensing configuration indicates sensing transmission power, waveform, and sensing resources and periodicity for the sensing signal, and may configure the UE to one of receive or transmit an object detection report.
