MTC Terminal Power Reduction via Shared Measurement Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 4G wireless communication systems, MTC terminals face challenges in achieving low power consumption due to the need for repeated measurements of measurement information, which is difficult to achieve with existing technologies.
Innovation Solution
The proposed solution involves a wireless communication system where the eNodeB broadcasts measurement information, allowing MTC terminals to share and use this information instead of performing redundant measurements, thereby reducing power consumption and signaling between the eNodeB and MTC terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If each MTC terminal performs repeated measurements to obtain measurement information, then measurement accuracy is improved, but power consumption increases
Solution Approach 1:
Multiple terminals share measurement information through a common measurement result database. Instead of each terminal performing independent repeated measurements, they combine efforts by having one or fewer terminals perform measurements and share results with others, thereby maintaining measurement accuracy while reducing overall power consumption.
Solution Approach 2:
Measurement information is pre-acquired and stored in a database before being requested by terminals. The measurement results are prepared in advance and can be directly utilized by multiple terminals without requiring them to perform measurements themselves, thus reducing power consumption while ensuring measurement accuracy is available when needed.
2Reliability
If each MTC terminal performs repeated measurements, then reliable communication is improved, but signaling between eNodeB and terminals increases
Solution Approach 1:
Multiple terminals share measurement information through a common database, reducing the number of individual measurement reporting signals. Instead of each terminal sending measurement reports to the eNodeB, terminals can retrieve shared measurement results from the database, thereby maintaining communication reliability while significantly reducing signaling complexity between eNodeB and terminals.
3Reliability
If MTC terminals frequently access the network for measurements, then communication quality is improved, but network access overhead increases
Solution Approach 1:
Measurement information is pre-acquired and stored in a database before being requested by terminals. Terminals can access pre-prepared measurement results without needing to initiate frequent network access procedures, thus maintaining communication quality while reducing network access time and overhead.
