Sidelink Resource Timing for Type-1 Grants and Cross-RAT Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack a clear method for determining the sidelink transmission timepoint for type-1 configured grant and cross-RAT scheduling in sidelink communication, affecting the stability and flexibility of the transmission process.
Innovation Solution
A method and system for configuring sidelink transmission resources that involve receiving scheduling information from a network device, allowing the terminal to determine the start timepoint of sidelink transmission as the first available resource in a resource pool not earlier than a target timepoint, associated with a time-related parameter derived from the terminal or scheduling information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If type-1 configured grant and cross-RAT scheduling are used for sidelink transmission, then resource allocation flexibility is improved, but the method for determining transmission timepoint is unclear
Solution Approach 1:
The patent introduces a timeOffset parameter that can be dynamically configured by the network device to adjust the transmission timepoint. This parameter change mechanism allows the system to adapt to different scheduling scenarios (type-1 configured grant and cross-RAT scheduling) by modifying the time offset value, thereby making the transmission timepoint determination clear and controllable while maintaining resource allocation flexibility.
2Loss of time
If terminal autonomously selects transmission resources in mode B, then transmission delay is reduced, but transmission timepoint determination for type-1 SL CG and cross-RAT is unclear
Solution Approach 1:
The patent enables the terminal to autonomously determine its transmission timepoint by calculating the first available resource not earlier than the target timepoint (current timepoint plus timeOffset). This self-service mechanism allows the terminal to independently resolve the transmission timepoint determination issue for type-1 configured grant and cross-RAT scheduling, maintaining the low transmission delay benefit of autonomous resource selection while providing clear timepoint determination rules.

AI summary
Disclosed are a sidelink transmission resource configuration method and system, and a device and a storage medium. In the method, a terminal device can receive scheduling information from a network device, and determine a first available resource, which is not earlier than a target moment, in a resource pool to be a sidelink transmission moment, wherein the target moment is related to a time correlation parameter, and the time correlation parameter can be from the scheduling information or a terminal. According to the method, a sidelink transmission moment of a terminal can be determined, thereby making up for the defect in the prior art of there being a lack of solutions for determining a sidelink transmission moment, and improving the stability and flexibility of a sidelink transmission process.
