Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing V2X communication systems in LTE networks face inefficiencies due to peer-to-peer mesh architectures, which result in high costs and incompatibility with infrastructure-based cellular networks, leading to suboptimal spectrum utilization and increased costs for separate spectrum allocation.
Innovation Solution
A wireless communication framework that introduces a scheduler user equipment node to coordinate radio resource allocation among user equipment nodes, enabling direct data transmission and reducing interference through synchronized resource scheduling, while maintaining compatibility with hierarchical network architectures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a peer-to-peer mesh architecture is used for V2X communications, then infrastructure independence is achieved, but spectrum efficiency deteriorates and costs increase
Solution Approach 1:
The patent introduces a scheduler UE as an intermediary node that coordinates resource allocation among multiple UEs. This mediator enables infrastructure-independent operation while achieving centralized-like resource management efficiency, resolving the contradiction between infrastructure independence and spectrum efficiency.
Solution Approach 2:
The patent segments the network into groups managed by scheduler UEs, where each scheduler UE manages a specific group of UEs. This segmentation allows the system to achieve infrastructure independence through distributed scheduling while maintaining efficient resource utilization within each group.
2Adaptability or versatility
If a peer-to-peer mesh architecture is used for V2X communications, then infrastructure independence is achieved, but device complexity increases due to separate spectrum allocation requirements
Solution Approach 1:
The patent enables the PC5 interface to serve dual purposes: direct V2X communications and coordinated resource allocation. The scheduler UE uses the same interface for both data transmission and scheduling control, eliminating the need for separate spectrum allocation and reducing system complexity.
3Loss of energy
If centralized resource scheduling is implemented through a scheduler UE, then spectrum efficiency improves, but control overhead increases
Solution Approach 1:
The patent implements partial centralized scheduling where only resource allocation decisions are centralized through the scheduler UE, while data transmission remains distributed. This partial centralization achieves spectrum efficiency without requiring complete control overhead of traditional centralized systems.
Data Source
AI summary
The described technology is generally directed towards operating a user equipment node as a scheduler user equipment (e.g., which can be a local manager of other nodes in a group). The scheduler user equipment receives a scheduling request for the scheduling of the resources for transmission of data by a transmitter user equipment, and based on the traffic type requested, schedules the transmitter user equipment and receiver user equipment(s) with scheduling data/allocated radio resources. The transmitter user equipment can directly transmit to the receiver user equipment(s) on the allocated radio resources, e.g., without further involvement of the scheduler user equipment/local manager. For cellular data, the scheduler user equipment can schedule the transmitter user equipment to transmit to the scheduler user equipment as a receiver node.
