Dynamic Resource Sharing Between WWAN and WLAN
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing resource sharing between different radio access technologies (RATs) such as WWAN and WLAN, leading to suboptimal performance in terms of throughput and resource utilization.
Innovation Solution
A method where user equipment (UE) determines whether to configure for short-term or long-term resource sharing between WWAN and WLAN by assessing performance parameters like channel quality indicators and throughput, and reconfigures resources accordingly to optimize usage across multiple RATs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If resources are statically allocated to a single RAT, then resource configuration simplicity is maintained, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent implements dynamic resource allocation between WWAN and WLAN RATs by allowing the UE to reconfigure resources based on real-time performance parameters. The system transitions from static to dynamic resource sharing, where resources can be allocated to different RATs based on current channel conditions, application requirements, and network state, thereby improving resource utilization efficiency while managing complexity through structured reconfiguration procedures
Solution Approach 2:
The patent changes the allocation parameters of UE resources between different RATs based on performance metrics. By monitoring parameters such as channel quality indicators, throughput, and application requirements, the system adjusts resource allocation parameters dynamically, allowing the same physical resources to be optimized for different RATs under different conditions without requiring additional hardware resources
2Productivity
If resources are shared between WWAN and WLAN, then resource utilization efficiency improves, but performance stability deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the UE continuously monitors performance parameters such as channel quality indicators and throughput for both WWAN and WLAN. Based on this feedback, the system determines whether to maintain current resource allocation or reconfigure resources between RATs. This closed-loop control ensures that resource sharing improves overall utilization while maintaining performance stability by adapting to changing conditions rather than using fixed allocation rules
Solution Approach 2:
The patent performs preliminary assessment of performance parameters before executing resource reconfiguration. By evaluating channel conditions, application requirements, and current resource utilization in advance, the system determines the optimal resource allocation strategy before implementation. This preliminary action prevents premature or inappropriate reconfiguration that could destabilize performance while enabling timely optimization when conditions warrant it
3Productivity
If dynamic resource reconfiguration is implemented, then throughput is improved, but processing overhead increases
Solution Approach 1:
The patent implements partial resource reconfiguration rather than complete reallocation. Instead of reconfiguring all UE resources between RATs, the system selectively reconfigures only the specific resources that need optimization based on performance parameters. This partial action approach achieves throughput improvement by focusing reconfiguration efforts on bottleneck resources while minimizing the processing overhead associated with evaluating and executing comprehensive resource reallocation

AI summary
Aspects of the present disclosure generally relate to wireless communications. In some aspects, a user equipment (UE) may determine whether to configure the UE for a first type of resource sharing or a second type of resource sharing between a first radio access technology (RAT) and a second RAT, wherein one or more UE resources are configured for use with the first RAT. The UE may reconfigure the one or more UE resources for use with the second RAT based at least in part on determining whether to configure the UE for the first type of resource sharing or the second type of resource sharing.
