V2X Terminal Assisted Resource Scheduling via Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In V2X communication networks, the reliability and flexibility of resource scheduling are low due to terminal dependence on serving nodes for resource allocation, leading to failed data transmissions when outside the node's range or with unstable connections, and inefficient resource utilization in self-scheduling modes.
Innovation Solution
A method where terminals can acquire resources through assisted scheduling by other terminals, allowing them to receive configuration information for available resource sets and allocate target resources without direct serving node scheduling, improving resource utilization and scheduling reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal requests resources from a serving node, then resource allocation is centralized and controlled, but data transmission fails when the terminal is outside the serving node's range or connection is unstable
Solution Approach 1:
The patent introduces a second terminal as an intermediary to assist the first terminal in acquiring resources. The second terminal receives resource configuration from the serving node and transmits it to the first terminal, enabling resource acquisition without direct serving node involvement. This mediator approach resolves the contradiction by maintaining centralized resource management while enabling independent operation outside serving node coverage.
Solution Approach 2:
The patent segments the resource allocation process into two independent parts: (1) serving node configures resources for the second terminal, and (2) second terminal assists first terminal in acquiring resources. This segmentation allows the first terminal to obtain resources through an alternative path, improving reliability when direct serving node connection is unavailable.
2Adaptability or versatility
If a terminal performs self-sensing in a resource pool, then the terminal can independently select resources, but resource allocation becomes unreasonable and utilization is low
Solution Approach 1:
The second terminal provides feedback information about resource availability and transmission conditions to the first terminal. This feedback mechanism enables the first terminal to make informed resource selection decisions, combining independent operation with optimized resource allocation based on actual network conditions, thus resolving the contradiction between independence and efficiency.
Solution Approach 2:
The second terminal acts as an intermediary that provides the first terminal with configured resource information from the serving node. This mediator approach allows the first terminal to independently select resources while benefiting from centralized resource management knowledge, improving both adaptability and allocation efficiency.
3Device complexity
If a terminal depends on serving node for resource allocation, then resource management is centralized, but flexibility and reliability of resource scheduling are reduced
Solution Approach 1:
The patent segments resource management functions: the serving node maintains centralized resource configuration for the second terminal, while the second terminal independently assists the first terminal in resource acquisition. This segmentation enables flexible resource scheduling without compromising centralized management, resolving the contradiction between complexity and reliability.

AI summary
Provided are a method of resource acquisition, method for resource scheduling, terminal, serving node, and medium. The resource acquisition method is applied at a first terminal, including: receiving configuration information, transmitted by a second terminal, of an available resource set in a case where a predefined condition is satisfied; acquiring a target resource based on the configuration information of the available resource set, a target resource is used for transmitting service data.
