Multi-Carrier Sidelink Configuration for 5G V2X Data Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G NR-V2X communication systems are limited by supporting only single-carrier sidelink communication, which restricts data transmission capacity and communication quality, especially for large data requirements.
Innovation Solution
A wireless communication method that allows transmission user equipment (Tx UE) to request and configure multiple carriers for sidelink communication with reception user equipment (Rx UE), enabling the selection of a primary carrier and potentially switching to alternative carriers if the initial primary carrier fails to establish a sidelink connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If single-carrier configuration is used for sidelink communication, then device complexity is reduced, but data transmission capacity is limited
Solution Approach 1:
The patent segments the communication spectrum into multiple carriers (first carrier and second carrier) for sidelink communication. The network device configures different carriers with different parameters (frequency, bandwidth, etc.) to handle different data transmission requirements, thereby increasing overall data transmission capacity while maintaining manageable complexity through structured configuration management.
Solution Approach 2:
The patent transitions from single-carrier to multi-carrier configuration by adding the carrier dimension to the communication system. This allows simultaneous transmission on multiple frequency resources, effectively increasing data transmission capacity by utilizing an additional spectral dimension rather than being constrained to a single carrier.
2Reliability
If single carrier is used for data transmission, then resource allocation is simplified, but communication quality deteriorates when large data communication requirement exists
Solution Approach 1:
The patent implements dynamic resource allocation across multiple carriers where the network device can flexibly assign different carriers (first carrier or second carrier) based on real-time communication requirements, channel conditions, and data volume. This dynamic multi-carrier resource allocation improves communication quality for large data transmissions while maintaining efficient resource utilization through adaptive management.
3Productivity
If multiple carriers are configured for sidelink communication, then data transmission capacity increases, but device complexity increases
Solution Approach 1:
The patent implements self-service mechanisms where the network device autonomously manages multi-carrier configuration based on received indication information. The system automatically determines whether to configure one or two carriers, selects appropriate carrier parameters, and manages resource allocation without requiring complex manual intervention, thereby increasing data transmission capacity while controlling configuration complexity through automated decision-making.
