Resource Pool Assignment for Bandwidth Part Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, switching between different resource pools is time-consuming, which affects the efficiency of resource allocation and communication performance.
Innovation Solution
The method involves assigning a first plurality of resource pools to a first bandwidth part, where each resource pool corresponds to a different numerology or maximum physical sidelink shared channel duration, and transmitting information indicating this assignment, along with a mapping between a priority list and the resource pools, to enable efficient resource pool management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If resource pools are assigned to different bandwidth parts with different numerologies, then resource allocation flexibility is improved, but switching time between resource pools increases
Solution Approach 1:
The patent divides the resource pool configuration into multiple bandwidth parts, where each bandwidth part contains specific resource pools with designated numerologies. This segmentation allows the system to organize resource pools in a structured manner, enabling faster switching by selecting entire bandwidth parts rather than individual resource pools, thus resolving the contradiction between allocation flexibility and switching time.
Solution Approach 2:
The patent pre-assigns multiple resource pools to each bandwidth part during configuration phase. This preliminary action enables the UE to quickly switch between resource pools by simply switching bandwidth parts without performing time-consuming reconfiguration, thereby reducing switching time while maintaining the ability to allocate resources flexibly across different numerologies.
2Adaptability or versatility
If multiple resource pools with different numerologies are configured, then support for diverse communication requirements is improved, but system complexity increases
Solution Approach 1:
The patent creates bandwidth parts that serve as universal containers for multiple resource pools with different numerologies. Each bandwidth part can hold resource pools suitable for various communication requirements (e.g., different subcarrier spacings for different services), allowing a single bandwidth part structure to handle diverse requirements without creating separate complex configuration structures for each numerology type.
Solution Approach 2:
The patent introduces a hierarchical dimension to resource pool organization by mapping resource pools to bandwidth parts. This additional organizational layer simplifies the system by providing a unified management structure that handles multiple numerologies through a common bandwidth part framework, reducing the complexity that would arise from direct management of numerous individual resource pools with different characteristics.
3Productivity
If resource pools are switched frequently to optimize allocation, then resource utilization efficiency is improved, but communication latency increases
Solution Approach 1:
The patent pre-configures multiple resource pools within each bandwidth part during the initial setup or reconfiguration phases. This preliminary configuration enables the UE to perform rapid resource pool switching by simply activating different bandwidth parts without undergoing time-consuming reconfiguration processes, thus improving resource utilization efficiency while minimizing the latency impact of switching.
