MBSFN Measurement Data Transmission Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for transmitting broadcast-multicast single-frequency network (MBSFN) measurement data result in high transmission overhead due to the reporting of numerous measurement parameters, which complicates network optimization and increases data transmission burden.
Innovation Solution
The proposed solution involves preprocessing the measurement data to reduce its size by calculating differences between measured values or reporting only the worst or average values, thereby reducing the transmission overhead while still enabling effective network optimization and modulation/coding for MBMS transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large number of measurement parameters are reported for network optimization, then the network optimization effectiveness is improved, but the transmission overhead increases
Solution Approach 1:
The patent extracts only the most critical measurement parameters (such as MBSFN RSRP, RSRQ, and CQI) from the complete set of available measurement data. By selecting and reporting only these essential parameters rather than all measured values, the system maintains network optimization effectiveness while significantly reducing the transmission overhead of measurement reports.
Solution Approach 2:
The patent employs simplified measurement reporting mechanisms that use less precise but sufficient parameter representations. Instead of reporting complete and detailed measurement datasets, the system uses condensed parameter sets that are easier and less resource-intensive to transmit, achieving acceptable network optimization with reduced transmission costs.
2Measurement precision
If all measurement parameters are transmitted to the base station, then the measurement precision is improved, but the transmission overhead and data processing complexity increase
Solution Approach 1:
The patent applies different quality levels of measurement data reporting based on local conditions and requirements. Critical parameters such as MBSFN RSRP, RSRQ, and CQI are reported with high precision, while less critical parameters are either omitted or reported with reduced precision. This localized quality approach ensures measurement precision where needed while reducing overall data transmission and processing complexity.
3Manufacturing precision
If multiple measurement parameters are reported for each cell, then the network optimization accuracy is improved, but the transmission time and overhead increase
Solution Approach 1:
The patent implements partial reporting of measurement parameters by selecting only the most essential parameters (MBSFN RSRP, RSRQ, and CQI) for transmission. This partial action approach provides sufficient network optimization accuracy without the need to report all available measurement parameters, thereby reducing transmission time and overhead while maintaining acceptable optimization performance.
