Per-area signal measurements for RIS security detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in 5G NR, face challenges in detecting and addressing issues with reconfigurable intelligent surfaces (RIS) such as security attacks or damage, which can lead to compromised beam quality and coverage, and lack efficient methods for determining active security attacks or weak signal strength across areas.
Innovation Solution
Assigning a primary node per area to collect and report measurements from multiple UEs, allowing the network node to analyze these measurements and determine if an RIS is compromised, enabling remedial actions like activating backup RIS or adjusting TRP power to maintain communication quality.

Engineering Contradiction Analysis
1Reliability
If per-area measurement reporting is implemented to detect RIS compromise, then security detection capability is improved, but network signaling overhead and complexity increase
Solution Approach 1:
The system divides the network into multiple areas, each with a designated primary node responsible for collecting measurements from UEs in that area. This segmentation distributes the measurement collection responsibility across multiple primary nodes rather than requiring all UEs to report to a single central entity, reducing overall network signaling overhead while maintaining comprehensive security monitoring coverage.
Solution Approach 2:
Primary nodes act as intermediary entities between UEs and the network. Instead of UEs directly communicating with the network for measurement reporting, the primary node collects measurements from multiple UEs in its area and consolidates the information before reporting to the network, thereby reducing redundant signaling and processing overhead.
2Measurement precision
If multiple UEs report measurements to a primary node for area-based analysis, then measurement coverage and detection accuracy are improved, but processing time and energy consumption increase
Solution Approach 1:
The system pre-configures primary nodes for each area before measurement collection begins. This preliminary assignment of primary nodes to specific areas allows for organized and efficient measurement collection, reducing the time required for dynamic node selection and coordination during the actual measurement process.

AI summary
In an aspect, a primary node receives a first request, originating from a network node, to report measurements collected for communication with the network node within an area. The primary node also receives the measurements from multiple UEs in the area. The primary node further reports measurement information collected from the multiple UEs within the area.
