Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently sharing data-decoding and reference signal information among multiple transmitters to facilitate multi-node passive sensing, particularly in environments where devices rely on high data rates, high reliability, and low latency, such as in 5G and New Radio technologies.
Innovation Solution
A method and apparatus for wireless communication that enable the sharing of reference signal information and data-decoding parameters among multiple transmitters and receivers, allowing for the monitoring and decoding of signals intended for other devices, including the use of transceivers, memory, and processors to facilitate multi-node passive sensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication systems share data-decoding and reference signal information among multiple transmitters, then multi-node passive sensing capability is improved, but system complexity and information management overhead increase
Solution Approach 1:
The patent segments the information sharing process into distinct components: reference signal information is shared separately from data-decoding parameters, and each transmitter-receiver pair has dedicated configuration messages. This segmentation allows the system to enable multi-node passive sensing while managing complexity through modular information exchange rather than comprehensive system-wide sharing.
Solution Approach 2:
The patent introduces configuration messages as intermediary carriers that facilitate information sharing between transmitters and receivers. These messages act as standardized intermediaries that translate complex sensing requirements into manageable communication protocols, reducing system complexity while enabling versatile passive sensing capabilities across multiple nodes.
2Measurement precision
If devices monitor signals intended for other devices, then passive sensing accuracy is improved, but data rate and latency requirements become more stringent
Solution Approach 1:
The patent applies preliminary action by having transmitters send configuration messages containing reference signal information and data-decoding parameters before the actual sensing signals are transmitted. This advance preparation allows receivers to pre-configure their monitoring capabilities, enabling accurate passive sensing without requiring real-time processing that would compromise data rate and latency performance.
3Reliability
If reference signal information is shared for line-of-sight signals targeting other UEs, then sensing reliability is improved, but information management overhead increases
Solution Approach 1:
The patent extracts only the essential reference signal information and data-decoding parameters needed for passive sensing, separating them from the complete communication protocol stack. By taking out only the necessary sensing-related configuration data and sharing it through dedicated configuration messages, the system improves sensing reliability while minimizing information management overhead by excluding unnecessary communication details.
