Dynamic Resource Pools for Configured Grant Uplink
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in managing uplink communications due to the challenges of dynamic resource allocation and traffic variability, particularly in scenarios with a large number of reduced-capability user equipment (UEs), leading to increased delay, control overhead, and resource wastage.
Innovation Solution
Implementing dynamic resource pools for configured grant uplink communications, where base stations can adjust the number of resources available to UEs based on traffic thresholds, using mechanisms like statistical multiplexing and adaptive resource allocation to optimize resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dynamic resource allocation is implemented for uplink communications, then resource utilization efficiency is improved, but control overhead and scheduling complexity increase
Solution Approach 1:
The patent applies preliminary action by configuring resource pools in advance with pre-defined resource allocations for configured grant uplink communications. UEs are provided with predetermined resource pools that include multiple resources available for CG UL communications, eliminating the need for dynamic scheduling decisions at transmission time. This preliminary configuration reduces control overhead while maintaining efficient resource utilization through statistical multiplexing.
2Reliability
If the number of configured grant resources is increased to handle traffic variability, then uplink communication reliability is improved, but resource wastage increases
Solution Approach 1:
The patent applies dynamics by enabling flexible adjustment of the number of resources available in configured resource pools based on traffic conditions. The system can dynamically configure resource pools to include different numbers of resources depending on traffic variability and UE activity patterns. This dynamic configuration ensures sufficient resources are available for reliable CG UL communications while avoiding permanent allocation of excessive resources that would lead to wastage during low traffic periods.
3Productivity
If statistical multiplexing is used to optimize resource pools, then resource utilization is improved, but delay in resource allocation increases
Solution Approach 1:
The patent resolves this contradiction by applying preliminary action through pre-configuration of resource pools with multiple pre-allocated resources. UEs have immediate access to predetermined resources within the configured pools without requiring real-time scheduling decisions. This eliminates resource allocation delay while maintaining high resource utilization through statistical multiplexing, as multiple UEs can share the pre-configured resource pools based on their traffic needs.
