LTE Buffer Status Report Segmentation for Scheduling Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In LTE communications systems, the granularity of buffer status reports per logic channel group leads to inefficient utilization of air interface resources, as the evolved NodeB can only schedule resources based on group priorities, lacking precision.
Innovation Solution
User equipment determines processing indication information based on the type of buffered uplink data and generates a buffer status report that includes this information, allowing the evolved NodeB to perform more precise scheduling and resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the granularity of buffer status report is per logic channel group, then the reporting structure is simple, but the scheduling precision deteriorates and air interface resources cannot be utilized effectively
Solution Approach 1:
The patent segments the buffer status report by introducing multiple buffer status fields (first buffer status field, second buffer status field, third buffer status field) corresponding to different data types (first type, second type, third type) within the same logic channel group. This segmentation allows the eNB to obtain precise buffer status information for each data type, enabling differentiated scheduling decisions while maintaining a unified reporting structure.
2Productivity
If the eNB schedules resources based on logic channel group priority only, then the scheduling process is simple, but the resource allocation efficiency deteriorates
Solution Approach 1:
The patent applies local quality by enabling the eNB to perform differentiated scheduling based on data type characteristics. The eNB can allocate resources with different priorities, modulation and coding schemes, and resource block assignments for different data types (first type, second type, third type) within the same logic channel group, optimizing resource utilization for each data type's specific requirements rather than applying a uniform scheduling approach.

AI summary
Embodiments of the present invention provide a transmission data processing method and devices. The transmission data processing method includes: determining, by user equipment UE, processing indication information according to a type of buffered uplink data, and generating a buffer status report; and sending, by the UE, the buffer status report to a base station eNB, so that the eNB performs scheduling and uplink transmission resource allocation on the UE according to the processing indication information. The transmission data processing method and the devices provided in the embodiments of the present invention avoid a defect that air interface resources cannot be utilized appropriately and effectively when a granularity of a reported buffer status report is per logic channel group, thereby improving effects of scheduling and resource allocation that are performed on UE.
