Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radar systems require separate hardware systems for sensing and communication, leading to increased size and cost.
Innovation Solution
Implement a communication apparatus with shared antenna panels for both sensing and communication functions, allowing different panels to be allocated for either function based on need, reducing mutual interference and eliminating the need for separate hardware systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two separate hardware systems (radio frequency circuits and antennas) are used for sensing and communication, then sensing and communication functions can be independently implemented, but the size and cost of the radar system increase
Solution Approach 1:
The patent combines sensing and communication functions into a single hardware system by sharing antenna panels between the two functions. The radar system uses one set of antenna panels that can be dynamically allocated to either sensing or communication operations, eliminating the need for separate dedicated antenna systems while maintaining functional independence through software control and signal processing.
Solution Approach 2:
The antenna panels are designed with multi-functionality, capable of serving both sensing and communication purposes. The system dynamically determines which antenna panels to allocate to sensing and which to communication based on real-time operational requirements, enabling a single hardware component to perform multiple functions that traditionally required separate dedicated systems.
2Adaptability or versatility
If two separate hardware systems are used for sensing and communication, then functional independence is maintained, but costs increase
Solution Approach 1:
By merging sensing and communication into a single hardware platform with shared antenna panels, the patent reduces overall system cost. The elimination of duplicate antenna systems and radio frequency circuits directly lowers manufacturing expenses while functional independence is preserved through dynamic resource allocation and software-based signal separation.
Solution Approach 2:
The universal antenna panel design that supports both sensing and communication operations eliminates the need for purchasing and maintaining separate dedicated hardware systems. This multi-functional approach reduces total cost of ownership while maintaining the ability to independently perform sensing and communication tasks through intelligent resource management.
3Device complexity
If antenna panels are shared between communication and sensing, then hardware size is reduced, but mutual interference between functions increases
Solution Approach 1:
The system dynamically allocates antenna panels to sensing or communication functions based on real-time operational needs. The dynamic determination of which panels to use for which function allows the system to adapt to varying interference conditions and optimize performance, reducing mutual interference through time-varying resource allocation rather than static dedicated assignments.
Solution Approach 2:
The antenna system is segmented into multiple independent antenna panels that can be individually allocated to different functions. This segmentation allows fine-grained control over which panels perform sensing and which perform communication, enabling the system to spatially separate functions and reduce mutual interference by assigning different panels to different operations simultaneously.

AI summary
A communication method and apparatus are provided. The communication apparatus communicates with a device to obtain first information that includes location information and/or motion information of the device, and senses an environment to obtain environment sensing information that includes location information and/or motion information of an object in the environment. The communication apparatus determines a first antenna panel and/or a second antenna panel different from the first antenna panel based on the first information and the environment sensing information, where the first antenna panel is configured to communicate with a first device, and/or is configured to send, to the first device, a signal for sensing information, the second antenna panel is configured to receive sensing signal from the first device. In the communication apparatus, sensing and communication functions can be implemented in a single hardware system, thereby decreasing a size of the communication apparatus and reducing the cost.
