Base Station Data Subsets for LTE-MTC Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LTE network maintenance costs are high due to the need for multiple radio access technologies, and Machine-Type Communications (MTC) devices rely on GSM/GPRS networks for low-cost, low-data rate applications, which limits efficient data communication in cellular systems.
Innovation Solution
A method and system for a base station that groups data into subsets, encodes, and modulates them for transmission, using a communication protocol module to optimize data transmission to receiving devices, allowing for disjoint or overlapping data subsets based on reception quality and coverage targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted using traditional LTE broadcast channels, then coverage is sufficient, but network maintenance costs are high due to multiple radio access technologies
Solution Approach 1:
The patent segments the data transmission process by dividing data into multiple subsets and transmitting them through different channels (dedicated physical data channel and physical broadcast channel). This segmentation allows the system to maintain reliable coverage through broadcast channels while reducing network complexity by enabling MTC devices to use simpler GSM/GPRS infrastructure for low-data-rate applications
2Ease of manufacture
If MTC devices use GSM/GPRS network for low-cost applications, then device cost is reduced, but data communication efficiency is limited
Solution Approach 1:
The patent merges the capabilities of LTE and GSM/GPRS networks by enabling MTC devices to utilize both the LTE broadcast channel for essential network information and the GSM/GPRS network for data transmission. This combination allows devices to maintain low cost while improving data communication efficiency through the more capable LTE infrastructure
3Reliability
If data is grouped into multiple subsets for transmission, then transmission performance is enhanced, but processing complexity increases
Solution Approach 1:
The patent segments data into multiple subsets that are transmitted through different channels with different reliability characteristics. The receiving device can reconstruct the original data by combining subsets from different channels, achieving enhanced transmission performance while managing decoder complexity through the structured segmentation approach
