Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently allocating resources for multi-slot transmissions in XR and Cloud Gaming applications, particularly in managing varying traffic patterns and packet sizes, leading to inefficiencies and potential overlaps in resource usage.
Innovation Solution
Implementing frequency domain adaptive resource configuration for multi-slot allocation, where each transmission block (TB) can have varying sizes and offsets, allowing for flexible resource allocation across different regions and granularities, and using DCI formats to dynamically adjust allocation patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fixed resource allocation is used for multi-slot transmissions, then resource management is simple, but resource utilization efficiency deteriorates due to inability to accommodate varying traffic patterns
Solution Approach 1:
The patent implements dynamic resource allocation where the network node can flexibly adjust frequency domain resource assignments for different transmission blocks within a multi-slot allocation. The resource allocation adapts to varying traffic patterns by allowing different start and length indicators (SLIVs) for different TBs, transforming the static allocation into a dynamic system that responds to actual traffic demands.
Solution Approach 2:
The patent changes the parameters of resource allocation by introducing frequency domain adaptability through multiple SLIV configurations. Each transmission block can have different frequency resource parameters (start position and length), allowing the system to optimize resource usage by adjusting these parameters based on traffic characteristics without changing the overall allocation structure.
2Reliability
If uniform resource allocation is applied to all transmission blocks, then allocation process is simple, but overlaps in resource usage occur due to varying packet sizes and traffic patterns
Solution Approach 1:
The patent applies local quality by allowing different resource allocation parameters for different transmission blocks within the same multi-slot allocation. Each TB can have its own start and length indicators (SLIVs), enabling localized optimization of frequency resources for each TB based on its specific traffic characteristics, thereby preventing overlaps while maintaining manageable complexity through structured configuration.
3Productivity
If flexible frequency domain resource allocation is implemented for each transmission block, then resource utilization efficiency improves, but system complexity increases
Solution Approach 1:
The patent segments the frequency domain resource allocation into multiple independent configurable parameters (different SLIVs for different TBs). This segmentation allows each transmission block to be allocated frequency resources independently, improving bandwidth utilization efficiency while managing complexity by breaking down the allocation process into discrete, manageable segments rather than requiring complex interdependent configurations.
