Buffer Status Reporting to Avoid Duplicate Data Volume Reports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, the current methods for reporting buffer status and delay status result in redundant reporting of data amounts, leading to resource wastage.
Innovation Solution
A method to prioritize and selectively send status reports, ensuring that data amounts are reported only once by configuring logical channels to report delay information or using a packet discard timer to avoid duplicate reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If both BSR and DSR are triggered and sent using the same uplink resource, then delay information and data amount information can be reported, but the data amount of the same data is reported repeatedly, causing resource waste
Solution Approach 1:
The patent extracts the data amount information from the DSR and reports it separately through the BSR. When a DSR is triggered, the terminal device identifies the data amount information contained in the DSR and reports this information through a BSR instead. This separation allows the DSR to focus on carrying delay information while the BSR carries the data amount information, avoiding redundant reporting and saving uplink resources.
2Manufacturing precision
If the terminal device sends both BSR and DSR to report complete status information, then scheduling accuracy is improved, but the complexity of status report management increases
Solution Approach 1:
The patent merges the reporting functions of BSR and DSR by having the terminal device send both reports simultaneously when both are triggered. The BSR carries data amount information while the DSR carries delay information, and both are transmitted together to provide the base station with comprehensive scheduling information. This merging approach maintains high scheduling accuracy while the patent simultaneously reduces management complexity through optimized triggering mechanisms.

AI summary
This application may be applied to the field of communication technologies, and provides a data amount reporting method, an apparatus, and a readable storage medium, to avoid repeatedly reporting a data amount of same data. 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.
