NR V2X Resource Pool Definitions Within Bandwidth Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resource pool designs for sidelink communications in V2X services do not fully leverage the advantages provided by the NR 5G standard, particularly in terms of bandwidth management and resource allocation efficiency.
Innovation Solution
The proposed solution involves a transceiver configured to utilize bandwidth parts (BWPs) with specific numerologies, which include multiple resource sets for sidelink communications. These resource sets are defined based on different criteria such as communication type, traffic type, operation mode, QoS requirements, and zonal location, allowing for efficient resource allocation and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing resource pool designs are used for sidelink communications, then the basic communication function is maintained, but bandwidth management and resource allocation efficiency do not fully leverage NR 5G standard advantages
Solution Approach 1:
The patent segments the bandwidth into multiple bandwidth parts (BWPs), each with different numerologies and resource pool configurations. This allows the system to allocate resources more efficiently by selecting appropriate BWPs for different communication scenarios, thereby improving resource allocation efficiency while maintaining adaptability through the segmented structure.
Solution Approach 2:
The patent introduces dynamic BWP configuration where the active BWP can be switched based on communication requirements. The resource pools within each BWP are dynamically configured with different parameters (subcarrier spacing, bandwidth, time resources) to adapt to varying V2X communication needs, thus resolving the contradiction between efficiency and adaptability.
2Manufacturing precision
If multiple resource sets with different criteria are defined within a BWP, then resource allocation precision is improved, but system complexity increases
Solution Approach 1:
The patent divides the BWP into multiple resource sets, each associated with different criteria (communication type, traffic type, operation mode, QoS requirements, zonal location). This segmentation enables precise resource allocation for specific use cases while maintaining a structured organization that manages complexity through standardized classification categories.
Solution Approach 2:
Each resource set is designed to serve multiple purposes within its defined criteria, allowing a single resource set configuration to handle various communication scenarios. This multi-functionality reduces the need for entirely separate configurations, thereby improving allocation precision while controlling overall system complexity.

AI summary
A transceiver for a wireless communication system is described. The wireless communication system provides resources to be allocated for respective transmissions in the wireless communication system. The resources include one or more bandwidth parts, BWPs, a BWP having a certain numerology and including a plurality of subcarriers in the frequency domain. At least one of the BWPs includes a plurality of resource sets for a sidelink communication, the plurality of resource sets including at least a first resource set and a second resource set, the first resource set being associated with a first criterium, the second resource set being associated with a second criterium, and the first criterium and the second criterium being different. The transceiver is configured to use resources from one or more of the plurality of resource sets within the one BWP for a communication.
