Dynamic I2V V2V Resource Sharing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in resource allocation for Infrastructure-to-Vehicle (I2V) and Vehicle-to-Vehicle (V2V) communications, leading to wasted resources due to static partitioning, which does not account for varying traffic needs and channel usage over time and location.
Innovation Solution
Implementing a dynamic resource sharing mechanism between I2V and V2V communications using a shared resource pool, where resources are selected in frequency and time, and priority levels are identified to optimize bandwidth usage and resource reservation, ensuring guaranteed resources for I2V communications while allowing fair prioritization and efficient use of resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If static resource partitioning is used for I2V and V2V communications, then resource allocation is simple and predictable, but resource efficiency deteriorates due to wasted resources that do not account for varying traffic needs and channel usage
Solution Approach 1:
The patent implements dynamic resource sharing where the resource pool is dynamically allocated between I2V and V2V communications based on real-time traffic conditions and channel usage. The system transitions from static partitioning to dynamic allocation, allowing resources to adapt to varying demands while maintaining manageable complexity through structured resource pool management.
Solution Approach 2:
The patent creates a universal resource pool that serves both I2V and V2V communications, allowing the same resources to be shared between different communication types. This multi-functional resource pool improves efficiency by eliminating dedicated resource silos while maintaining clear allocation rules for each communication type.
2Productivity
If dynamic resource sharing is implemented between I2V and V2V communications, then resource efficiency improves, but system complexity increases due to priority level management and resource coordination
Solution Approach 1:
The patent segments the resource pool into distinct allocation zones for I2V and V2V communications, with defined priority levels and access rules. This segmentation manages complexity by creating structured boundaries while allowing dynamic sharing within those boundaries, balancing efficiency gains with system manageability.
Solution Approach 2:
The patent introduces an intermediary resource management mechanism that coordinates between I2V and V2V communications, handling priority arbitration and resource allocation decisions. This intermediary layer simplifies the complexity by centralizing coordination logic and providing clear rules for resource access without requiring complex peer-to-peer negotiation between communication types.
3Reliability
If priority levels are assigned for I2V communication from a unique set, then I2V communication reliability is improved, but V2V communication resources may be deprived
Solution Approach 1:
The patent changes the parameter of resource allocation from static to dynamic, allowing the system to adjust resource distribution based on priority levels while ensuring minimum guarantees for V2V communications. This parameter change enables I2V to receive preferential treatment when needed while preventing complete resource deprivation of V2V through enforced allocation boundaries.
Solution Approach 2:
The patent applies local quality by assigning different priority levels and resource access characteristics to different communication types within the same resource pool. I2V communications receive higher priority in critical scenarios while V2V communications maintain guaranteed minimum resources, creating localized quality differences that satisfy both reliability and fairness requirements.
Data Source
AI summary
Aspects are provided for dynamic resource sharing between V2V and I2V communications. A wireless device selects resources from a shared resource pool in frequency and time. The shared resource pool is shared for I2V communication and communication over a PC5 interface originating from a User Equipment (UE). The wireless device identifies a first priority level for communication from a set of priority levels for I2V communication and UE originated communication. The set of priority levels may comprise at least one priority level unique to the I2V communication.
