Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for classifying coverage scenarios in Machine-to-Machine (M2M) communications, such as RSRP-based and cell detection-based approaches, face challenges in tolerances and diversity, leading to uncertainty in determining whether to operate in normal or enhanced coverage mode, especially under varying signal conditions.
Innovation Solution
A method that determines radio conditions and maps them to standardized metrics like RSRP, RSRQ, or RS-SINR, allowing a handler to manage radio resources and adapt operations between conventional and enhanced coverage modes, ensuring consistent behavior across diverse MTC implementations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If RSRP-based or cell detection-based approaches are used to classify coverage scenarios, then coverage classification can be performed, but uncertainty arises in determining operation mode under varying signal conditions due to tolerances and diversity
Solution Approach 1:
The patent changes the parameter used for coverage classification from RSRP-based or cell detection-based metrics to a timing-based parameter (cell detection time). This timing parameter provides more consistent and precise differentiation between normal and enhanced coverage modes, reducing uncertainty in operation mode determination under varying signal conditions.
2Reliability
If coverage enhancing techniques are employed in enhanced coverage mode, then signal reception is improved, but device complexity and energy consumption increase
Solution Approach 1:
The patent implements a self-service mechanism where the device autonomously determines its own coverage mode by measuring cell detection time and comparing it against thresholds. This self-determination eliminates the need for complex network-based classification systems, reducing device complexity while maintaining reliable signal reception through appropriate coverage enhancing techniques.
3Reliability
If coverage enhancing techniques such as signal repetition are used, then signal reception reliability is improved, but energy consumption increases
Solution Approach 1:
The patent implements dynamic adaptation by adjusting coverage enhancing techniques based on the determined coverage mode. In normal coverage mode, standard reception procedures are used with minimal energy consumption. In enhanced coverage mode, coverage enhancing techniques such as signal repetition are activated to improve reliability. This dynamic approach optimizes energy consumption by applying enhancement techniques only when necessary.
