V2X Resource Allocation via Interest Indications for Multi-RAT Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies for V2X communications on multiple radio access technologies, such as LTE and NR, lack clarity in providing efficient backwards compatibility and advanced features, particularly in supporting simultaneous communications across different radio access technologies.
Innovation Solution
The system determines a change in vehicle-to-everything preference and transmits a remote unit interest indication to a network device, which then allocates resources based on the network's support type for V2X communications, including support for simultaneous communications on multiple radio access technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system supports simultaneous communications on multiple radio access technologies, then the adaptability and versatility of the system is improved, but the device complexity increases
Solution Approach 1:
The patent segments the V2X communication support by introducing separate network V2X support types (first, second, and third types) corresponding to different RATs. This segmentation allows the system to manage multiple radio access technologies independently while maintaining clear identification and allocation mechanisms, thereby reducing the complexity of handling multi-RAT communications.
Solution Approach 2:
The patent implements a universal network device that can support multiple V2X communication types through a single integrated framework. The network device is designed to handle first V2X communications on a first RAT, second V2X communications on a second RAT, and third V2X communications on a third RAT, providing multi-functionality that reduces overall system complexity while maintaining versatility.
2Adaptability or versatility
If the network device provides V2X resources for multiple radio access technologies, then the adaptability is improved, but the resource allocation complexity increases
Solution Approach 1:
The patent applies local quality by providing dedicated resource pools for each V2X communication type. The first resource pool is allocated for first V2X communications on the first RAT, the second resource pool for second V2X communications on the second RAT, and the third resource pool for third V2X communications on the third RAT. This localized resource allocation simplifies the overall resource management by treating each RAT independently while maintaining adaptability.
3Ease of operation
If the system determines and transmits interest indications for V2X preferences, then the ease of operation is improved, but the signaling overhead increases
Solution Approach 1:
The patent implements preliminary action by having the remote unit determine and transmit its V2X interest indication before actual resource allocation occurs. The remote unit indicates its preference for a particular RAT in advance, allowing the network device to prepare and allocate appropriate resource pools proactively. This preliminary indication mechanism simplifies the overall operation by establishing communication preferences early, while the efficient use of interest indication messages minimizes signaling overhead.
