Dynamic Resource Reclamation for Forward Compatibility in NR Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly those using New Radio (NR) technology, face inefficiencies due to statically reserved resources for forward compatibility, which limits flexibility and efficiency, especially when mostly populated with legacy devices.
Innovation Solution
Implementing dynamic reclamation and reconfiguration of resources reserved for forward compatibility, allowing any services or cells/user equipment (UEs) to reuse these resources on a per-slot or periodic basis, based on conditions such as location, interference, and actual usage, through signaling indicating available resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If resources are statically reserved for forward compatibility, then future service deployment is enabled, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent implements dynamic resource allocation by allowing reserved resources to be temporarily reclaimed and reused when not needed for forward compatibility. The network entity can dynamically switch between reserving resources for future services and reusing them for current services based on actual demand, transforming a static reservation system into a dynamic one that adapts to changing conditions.
Solution Approach 2:
The system changes the state parameter of reserved resources from a fixed 'reserved' state to a variable state that can switch between 'reserved' and 'reusable' based on conditions. This parameter change allows the same physical resources to serve different purposes at different times, resolving the contradiction between maintaining forward compatibility and improving current resource utilization.
2Adaptability or versatility
If resources are statically reserved for forward compatibility, then future services can be deployed, but system flexibility deteriorates
Solution Approach 1:
The patent introduces dynamic control mechanisms that allow the system to flexibly adjust resource allocation based on operational needs. The network entity can dynamically determine when to reclaim reserved resources and when to maintain reservations, providing operational flexibility while preserving forward compatibility capabilities when needed.
Solution Approach 2:
The system employs periodic evaluation of resource usage conditions to determine whether reserved resources should be reclaimed or maintained. This periodic action allows the system to rhythmically switch between maintaining forward compatibility and improving operational flexibility, balancing both requirements through time-based control.
3Adaptability or versatility
If reserved resources are not reused, then forward compatibility is maintained, but spectral efficiency deteriorates
Solution Approach 1:
The patent implements a recover mechanism for reserved resources where resources are temporarily discarded from the reserved pool and recovered for current service usage when forward compatibility requirements are not active. This discarding and recovering process allows the system to maximize spectral efficiency by utilizing available resources while maintaining the capability to restore reservations when needed for future compatibility.
Solution Approach 2:
The system enables self-service resource management where reserved resources automatically become available for reuse when not required for forward compatibility, without needing external reallocation. This self-service mechanism improves spectral efficiency by allowing resources to serve current services autonomously while maintaining forward compatibility readiness when activated.
