Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems, particularly in LTE networks, lack an efficient method for measuring signal energy magnitude (RSSI) from undetected transmission points, leading to issues with interference detection and reporting, especially in scenarios like the 'hidden node' problem, where existing solutions do not provide specific procedures for RSSI measurement and reporting.
Innovation Solution
A terminal device and communication system that employ a measurement method and protocol stack to efficiently measure and report RSSI across multiple frequency bands, utilizing techniques like carrier aggregation and discovery signal measurement timing configurations to improve interference detection and reporting accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RSSI measurement is performed for each frequency to detect interference from undetected transmission points, then interference detection capability is improved, but measurement and reporting complexity increases
Solution Approach 1:
The patent segments the RSSI measurement and reporting process by introducing separate information elements for frequency-specific RSSI measurements. Instead of treating all frequencies uniformly, the system divides measurements into frequency-specific units that can be independently configured and reported, reducing overall complexity while maintaining comprehensive interference detection capability
Solution Approach 2:
The patent adds a frequency dimension to the RSSI measurement framework by introducing frequency-specific information elements and measurement configurations. This dimensional expansion allows the system to track interference across multiple frequencies simultaneously without requiring a completely new measurement architecture, thereby improving detection capability while managing complexity through structured extension
2Measurement precision
If measurement procedure is standardized for each cell, then measurement consistency is improved, but efficiency of reporting measurement results across multiple frequencies deteriorates
Solution Approach 1:
The patent creates a universal measurement framework that can handle both cell-specific and frequency-specific measurements through a common information element structure. The measurement configuration and reporting mechanisms are designed to be multi-functional, supporting standardized cell-based measurements while simultaneously enabling efficient frequency-specific reporting through the same architectural foundation
Solution Approach 2:
The patent merges cell-based and frequency-based measurement approaches into a unified reporting structure. By combining these previously separate measurement paradigms into a single framework that uses shared information elements and configuration mechanisms, the system achieves both measurement consistency across cells and efficient multi-frequency reporting without requiring separate procedural frameworks

AI summary
Provided is a technology related to a terminal device, a base station device, a communication system, a measurement method and an integrated circuit that efficiently perform cell measurement. The base station device configures a primary cell and one or more secondary cells to the terminal device, and indicates a measurement object, a reporting configuration including information indicating a threshold associated with an RSSI report and a report interval, and a measurement identity for linking the reporting configuration and the measurement object, to the terminal device. When, in each configured measurement identity, an associated reporting configuration includes information indicating the threshold associated with the RSSI report and the report interval, the terminal device periodically reports an average value of RSSIs measured in a duration of the report interval, and a percentage of the RSSIs being beyond the threshold as a measurement result.
