Status Report Multiplexing to Avoid Redundant 5G Buffer Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, the current methods for reporting data amounts through Buffer Status Reports (BSR) and Delay Status Reports (DSR) result in redundant reporting of data amounts, leading to resource wastage.
Innovation Solution
A data amount reporting method that prioritizes and selectively sends status reports, avoiding redundant reporting by configuring logical channels to report either data amounts or delay information, and canceling unnecessary reports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If both BSR and DSR are triggered to report data amount and delay information, then comprehensive status information is provided to the base station, but resource waste occurs due to repeated reporting of the same data amount
Solution Approach 1:
The patent extracts the data amount reporting function from the DSR when it would be redundant. Specifically, when a BSR is triggered and covers certain logical channels, the DSR excludes reporting data amounts for those same logical channels, thereby removing the redundant information while preserving the delay information reporting capability of the DSR.
Solution Approach 2:
The patent implements dynamic adjustment of reporting content based on the triggering relationship between BSR and DSR. The reporting behavior adapts according to whether a BSR has been triggered for the same logical channel, making the reporting mechanism flexible and context-dependent rather than static and fixed.
2Loss of information
If multiple status reports are sent simultaneously, then complete status information is reported, but transmission resource occupation increases
Solution Approach 1:
The patent merges the reporting functions of BSR and DSR by allowing them to be multiplexed in the same uplink transmission. When both are triggered, they are combined into a single transmission opportunity, reducing the number of separate transmissions required while maintaining complete status information reporting.
Solution Approach 2:
The patent segments the reporting content within the combined transmission by clearly delineating which logical channels are reported in BSR versus DSR. This segmentation prevents overlap and redundancy while ensuring complete coverage of all necessary status information.
3Reliability
If DSR reports data amount for all logical channels, then complete delay information is provided, but redundancy increases when combined with BSR
Solution Approach 1:
The patent applies different reporting strategies to different logical channels based on local conditions. For logical channels where BSR is triggered, the DSR reports only delay information without data amount. For logical channels where BSR is not triggered, the DSR reports both delay information and data amount. This local differentiation eliminates redundancy while preserving completeness.

AI summary
Related to the field of communication technologies, a data amount reporting method, an apparatus, and a readable storage medium to avoid repeatedly reporting a data amount of same data are provided. The method includes: a first device triggers a first status report, where the first status report includes a data amount and delay information of first data, and the first data is to-be-transmitted data of the first device. The first device triggers a second status report, where the second status report includes a data amount of second data, and the second data is to-be-transmitted data of the first device. The first device sends a target status report by using a first transmission resource, where the target status report includes the data amount of the first data.
