Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LTE V2X communication systems cannot effectively support future application scenarios such as fully intelligent driving and automatic driving, as they fail to meet the diverse service requirements of different terminals.
Innovation Solution
A resource configuration method and apparatus are developed to meet the service requirements of different terminals in an NR V2X scenario, involving the use of resource indication information to determine the quantity of symbols occupied by the PSCCH, allowing for flexible configuration of resources through time division multiplexing (TDM) and frequency division multiplexing (FDM) between the PSCCH and PSSCH.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a same control region is configured for all terminals that multiplex the PCFICH in LTE V2X, then the system complexity is reduced and ease of operation is improved, but the service requirements of different terminals cannot be met and adaptability deteriorates
Solution Approach 1:
The patent segments the control region configuration by introducing terminal-specific parameters (first parameter for first terminal, second parameter for second terminal) that divide the previously unified control region into differentiated configurations. This allows each terminal to have customized control resource allocation while maintaining systematic management through parameter-based differentiation.
Solution Approach 2:
The patent implements dynamic adaptability by allowing the control region configuration to change based on terminal-specific parameters. The base station dynamically assigns different first parameters to different terminals, enabling the system to adapt to varying service requirements of different terminals rather than using a static unified configuration.
2Ease of manufacture
If LTE V2X communication is used, then the system complexity is reduced and ease of manufacture is improved, but the reliability and throughput for future applications such as fully intelligent driving cannot be met
Solution Approach 1:
The patent applies parameter changes by introducing new configurable parameters (first parameter, second parameter, third parameter) that modify the control region characteristics. These parameter changes enable the system to achieve higher reliability and throughput required for intelligent driving applications while maintaining the familiar LTE V2X framework, effectively upgrading the system capabilities through parameter optimization.

AI summary
This application provides a resource configuration method and apparatus, and relates to the field of communications technologies, to resolve a problem that an existing resource configuration cannot meet service requirements of different terminals in an NR V2X scenario. The method includes: A first terminal obtains resource indication information, and sends sidelink control information and sidelink data information to a second terminal based on the resource indication information. The resource indication information is used to indicate a quantity of symbols occupied by the sidelink control information in one slot or mini-slot. The method is applied to a sidelink communication process.
