Resource Allocation for Directional V2X Sidelink Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current V2X communication systems fail to ensure efficient resource allocation and improved transmission performance, particularly in scenarios requiring confidential and directional internal communication for automatic platooning, where resource utilization efficiency is compromised due to non-secure and non-directional signal transmission.
Innovation Solution
A resource allocation method and device that sense configured resource pools, select optimal time-frequency resources, and transmit data using beams, ensuring efficient resource utilization and secure, directional communication by determining transmission and reception resources based on beam directionality and channel conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beamforming and directional transmission are implemented for secure communication, then transmission security and directionality are improved, but device complexity and resource allocation difficulty increase
Solution Approach 1:
The resource pool is segmented into multiple sub-pools, each dedicated to specific beam directions or transmission groups. This segmentation allows independent resource management for each directional beam, simplifying the allocation process while maintaining security through isolated resource assignment.
Solution Approach 2:
Resources are pre-configured and pre-allocated to different beam directions and transmission groups before actual data transmission. This preliminary action establishes a structured resource framework that guides subsequent directional transmissions, reducing real-time allocation complexity.
2Productivity
If multiple resource pools are configured for different transmission groups, then resource allocation efficiency is improved, but system complexity increases
Solution Approach 1:
The multiple resource pools are designed with universal structures and standardized configuration parameters, allowing them to serve different transmission groups while following common management rules. This multi-functionality approach enables efficient resource allocation across groups without proportionally increasing system complexity.
3Reliability
If beam-based directional communication is used, then transmission performance and security are improved, but resource sensing and selection complexity increase
Solution Approach 1:
The sensing process is localized to specific beam directions and resource sub-pools rather than requiring global resource pool analysis. Each transmission group senses only its designated directional resources, reducing sensing complexity while maintaining transmission performance through focused local optimization.

AI summary
The present disclosure provides a resource allocation method and a User Equipment (UE). The resource allocation method includes the following steps as configuring one or more resource pools, and sensing, by a UE, each configured resource pool to obtain a result of sensing, selecting, from a set of remaining candidate single time unit resources of each resource pool contained in the result of sensing, one candidate single time unit resource as a transmission resource, and transmitting, via the transmission resource, a packet to be transmitted which is borne by the transmission resource. The present disclosure also provides a method of sidelink communication performed by a control user equipment (CUE), which comprises determining transmission resources and reception resources for internal communication, transmitting data to member user equipments (MUEs) in the determined transmission resources, and receiving data from the MUEs in the determined reception resources.
