Sensing Signal Handling for Multi-Node Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile network technologies, particularly in 5G and 6G, face challenges in enabling proper sensing within networks when receiving nodes receive sensing signals from different transmitting nodes, as existing methods require self-transmitting and self-receiving nodes, limiting the ability to coordinate sensing signals effectively between nodes.
Innovation Solution
A method and system for sensing signal handling where a transmitting node or receiving node triggers a sensing signal transmission procedure, exchanging configuration information to ensure the receiving node is prepared to receive the signal, including parameters like bandwidth, waveform, and priority-based resource allocation, allowing for efficient sensing signal transmission between different nodes.

Engineering Contradiction Analysis
1Reliability
If self-transmitting and self-receiving nodes are used, then sensing can be performed within the network, but the receiving node cannot receive sensing signals from different transmitting nodes
Solution Approach 1:
The patent divides the sensing function into separate transmitting nodes and receiving nodes, allowing them to operate independently. The transmitting node sends sensing signals while the receiving node processes them, enabling multi-node sensing coordination without requiring self-transmitting and self-receiving capabilities in a single node.
Solution Approach 2:
The patent introduces a configuration message as an intermediary that carries sensing signal parameters from the transmitting node to the receiving node. This mediator enables the receiving node to properly receive and process sensing signals from different transmitting nodes by providing advance configuration information about signal characteristics.
2Reliability
If configuration information is exchanged between nodes, then the receiving node can be prepared to receive sensing signals, but signaling overhead increases
Solution Approach 1:
The patent applies preliminary action by sending the configuration message before the actual sensing signal transmission. This allows the receiving node to prepare its reception parameters in advance, ensuring reliable signal reception while minimizing the need for repeated configuration exchanges during the sensing process.
Solution Approach 2:
The patent changes the parameters of the configuration message to optimize signaling overhead. By carefully selecting which parameters to include in the configuration message (such as bandwidth, waveform type, and resource allocation), the system achieves adequate reception preparation with minimal signaling overhead.

AI summary
Embodiments of the present disclosure relate to a method of sensing signal handling. A sensing signal transmission procedure is triggered by a transmitting node or a receiving node. A sensing signal is transmitted the transmitting node, which is received by the receiving node. In case the transmitting node triggers the sensing signal transmission procedure, the transmitting node sends a request including a configuration of the sensing signal to the receiving node, the transmitting node asks the receiving node to receive the sensing signal based on the configuration, and the transmitting node transmits the sensing signal based on the configuration. In case the receiving node triggers the sensing signal transmission procedure, the receiving node sends a request including a suitable configuration of the sensing signal to the transmitting node, and the transmitting node transmits the sensing signal based on the suitable configuration to the receiving node.
