Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently coordinating multi-static sensing to improve communication reliability and data rates, especially in vehicular environments where mobility and blockages affect communication quality.
Innovation Solution
A roadside unit (RSU) coordinates multi-static sensing by requesting and receiving capability information from communication nodes, transmitting control messages with sensing parameters, and collecting multi-static sensing measurements to determine channel estimates, which are then shared with communication nodes to enhance communication parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-static sensing coordination is implemented to improve communication reliability and data rates, then communication quality is improved, but system complexity increases due to the need for coordinating multiple communication nodes
Solution Approach 1:
The patent introduces a coordinating entity (roadside unit or network entity) that acts as an intermediary to manage multi-static sensing operations. This mediator collects capability information from multiple communication nodes, determines optimal sensing parameters, coordinates the sensing operations, and distributes channel estimates to relevant nodes. By centralizing the coordination function, the system achieves improved communication reliability through coordinated multi-static sensing while the intermediary manages the complexity of coordinating multiple nodes.
2Measurement precision
If multi-static sensing measurements are collected from multiple communication nodes to improve channel estimation accuracy, then measurement precision is improved, but the quantity of data and processing requirements increase
Solution Approach 1:
The patent extracts and utilizes existing sensing measurements from multiple communication nodes that are already performing sensing operations for other purposes. Rather than requiring dedicated sensing hardware or generating entirely new measurement data, the system extracts channel state information and sensing measurements from the normal communication operations of multiple nodes. This extraction approach improves channel estimation accuracy by leveraging available data from multiple sources without proportionally increasing the total data quantity or processing burden.
3Adaptability or versatility
If capability information exchange and coordination messages are transmitted to enable multi-static sensing, then adaptability is improved, but communication overhead and latency increase
Solution Approach 1:
The patent merges the capability information exchange and coordination messaging for multi-static sensing with existing communication protocols and procedures. The coordinating entity utilizes existing signaling mechanisms and message formats already deployed in the wireless communication system to convey sensing capabilities, parameters, and results. By combining multiple functions into existing communication frameworks rather than introducing separate dedicated signaling channels, the system achieves the necessary adaptability for multi-static sensing coordination while minimizing additional communication overhead and latency.

AI summary
Methods, systems, and devices for wireless communications are described. A roadside unit (RSU) may transmit, to a first communication node, a request for multi-static sensing capability information associated with the first communication node. The RSU may receive a report indicating the multi-static sensing capability information for the first communication node. The RSU may transmit, in response to receiving the multi-static sensing capability information, a control message indicating one or more multi-static sensing parameters for the first communication node. The RSU may receive one or more multi-static sensing measurements obtained based at least in part on the one or more multi-static sensing parameters. The RSU may transmit, to the first communication node, a second communication node, or both, one or more channel estimates determined based at least in part on the one or more multi-static sensing measurements.
