Passive Radio Sensing With Partial Configurations for Measurement Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently coordinating passive radio sensing measurements across different transmissions at the sensing receive node without exposing data embedded within the transmitted signals, and in aggregating these measurements effectively for network-wide environmental awareness.
Innovation Solution
A network device provides partial transmission configurations to a sensing receive device, which performs passive radio sensing measurements based on these configurations, including angular and delay domain analyses, and reports the results, while a sensing controller device coordinates the measurements and configurations across multiple nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If passive sensing receives all transmissions from multiple sources, then the quantity of sensed information increases, but the device complexity increases due to difficulty in separating measurements from different transmissions
Solution Approach 1:
The patent segments the transmission configuration information into partial configurations that are selectively provided to sensing receive nodes. Instead of providing complete transmission configurations for all sources, the system provides only the necessary partial configurations (e.g., time-frequency resources, radiation patterns) needed for the node to separate and process measurements from specific transmission sources, thereby reducing processing complexity while maintaining sensing capability.
2Measurement precision
If the network provides complete transmission configurations to sensing nodes, then the measurement precision improves, but the loss of information increases due to exposure of embedded data
Solution Approach 1:
The patent extracts only the necessary configuration parameters needed for passive sensing measurements from the complete transmission configurations. The network provides sensing nodes with partial transmission configurations containing only the minimal required information (time-frequency resources, radiation patterns) necessary for measurement separation, while excluding embedded data and other sensitive information, thus achieving measurement precision without information leakage.
3Productivity
If the network aggregates measurements from multiple sensing nodes, then the productivity of network-wide environmental awareness increases, but the device complexity increases due to coordination requirements
Solution Approach 1:
The patent establishes a universal configuration framework where the network device provides standardized partial transmission configurations that can be applied across multiple sensing nodes. This universal approach enables consistent measurement collection from different nodes without requiring node-specific complex coordination, as the same configuration paradigm can be deployed network-wide to aggregate environmental awareness data efficiently.

AI summary
Various aspects of the present disclosure relate to a network entity, such as a sensing receive device, receives one or more partial transmission configurations from a network device, where the one or more partial transmission configurations include a subset of parameters defining a transmission configuration of a transmit device. The sensing receive device also receives one or more transmitted signals from the transmit device according to the received one or more partial transmission configurations, and transmits a report of passive radio sensing measurements according to a report configuration, the passive radio sensing measurements determined based at least in part on the one or more transmitted signals from the transmit device according to the received one or more partial transmission configurations.
