LTE Data Volume Reporting via Logical Channel Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In carrier aggregation systems, it is challenging for the network side to determine data volumes transmitted under different transmission modes due to the lack of clear reporting mechanisms for duplicated and non-duplicated data.
Innovation Solution
The method involves reporting data volumes using different logical channels, logical channel groups, destination addresses, or destination address identifiers, allowing the network side to distinguish between duplicated and non-duplicated data, and configuring reliability and priority information accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data duplication transmission is implemented using multiple RLC entities and logical channels, then reliability of data transmission is improved, but the network side cannot distinguish data volumes transmitted under different transmission modes
Solution Approach 1:
The patent segments data volume reporting by creating separate reporting mechanisms for duplicated and non-duplicated data. It divides the buffer status reporting into multiple parts, where each part corresponds to a specific RLC entity or logical channel group, enabling the network side to distinguish data volumes for different transmission modes while maintaining the reliability benefits of data duplication.
Solution Approach 2:
The patent introduces a new dimension for data volume reporting by using logical channel group identifiers and RLC entity identifiers as additional dimensions. This allows the network side to differentiate between duplicated and non-duplicated data volumes without affecting the transmission reliability, effectively adding an identification layer to the existing data transmission framework.
2Measurement precision
If separate reporting mechanisms are implemented for duplicated and non-duplicated data, then data volume distinguishability is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal reporting mechanism where the same buffer status reporting procedure is used for both duplicated and non-duplicated data. The reporting structure remains consistent, but additional identifier fields (logical channel group identifier, RLC entity identifier) are incorporated to enable differentiation. This multi-functional approach allows a single reporting mechanism to serve multiple purposes without significantly increasing system complexity.
Solution Approach 2:
The patent embeds identification information within the existing buffer status reporting structure. Rather than creating separate reporting systems, it nests the logical channel group identifiers and RLC entity identifiers inside the conventional buffer status report format. This nested approach allows precise data volume measurement while minimizing the increase in system complexity by reusing existing reporting frameworks.

AI summary
The present invention discloses a method for reporting a data volume of data duplication, user equipment, a network device, and a computer storage medium, where the method includes: sending information about data volumes of to-be-reported duplicated data and non-duplicated data to a network side, where the information about the data volumes of the duplicated data and the non-duplicated data is distinguished by using at least one of the following information: a logical channel, a logical channel group, a destination address, and a destination address identifier.
