Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in allocating precise uplink transmission resources, leading to resource size indication errors and wasted transmission resources, especially with variable data sizes in applications like cloud gaming and live streaming.
Innovation Solution
The implementation of a precise resource size table, which supplements the base buffer size table by dividing base size ranges into sub-ranges, allowing for more accurate resource size indications through enhanced signaling methods, including the use of a first and second indicator in Buffer Status Reports (BSRs) to determine the exact resource requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a base buffer size table is used for resource allocation, then device complexity is reduced and ease of operation is improved, but measurement precision of resource size requirements deteriorates
Solution Approach 1:
The patent divides the buffer size indication into two segments: a base buffer size table providing coarse-grained resource allocation, and a differential value providing fine-grained adjustment. This segmentation allows the system to achieve precise resource size indication while maintaining manageable table complexity through the separation of coarse and fine adjustment functions.
2Measurement precision
If a base buffer size table is used for resource allocation, then device complexity is reduced, but resource allocation precision deteriorates leading to indication errors
Solution Approach 1:
The patent implements a feedback mechanism where the differential value is calculated based on the difference between the actual buffer size and the base buffer size. This feedback loop enables continuous refinement of resource allocation precision, reducing indication errors and preventing waste of transmission resources by adjusting allocations based on actual needs.
3Measurement precision
If base size ranges are divided into sub-ranges with differential values, then resource size indication precision is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by using different levels of precision for different buffer size ranges. For smaller buffer sizes, the base table provides sufficient precision. For larger buffer sizes where precision is more critical, differential values are introduced. This localized approach to precision maintains overall system simplicity while providing enhanced precision where most needed.
