Sidelink MAC Reset Handling for Reusable SL Processes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for processing sidelink (SL) processes in V2X communication lack effectiveness, leading to a decrease in the quantity of available SL processes and impacting data receiving rates and reliability.
Innovation Solution
Implementing methods that include determining unoccupied SL processes by performing MAC reset on RRC connections, releasing association relationships, and clearing buffers to optimize SL processes, thereby allowing reuse for other data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If MAC reset is performed on RRC connection of sidelink, then data receiving reliability is improved, but quantity of available SL processes decreases
Solution Approach 1:
The patent applies the discarding and recovering principle by releasing the association relationship between SL processes and RRC connections. When MAC reset is performed, instead of permanently losing SL process associations, the system releases these associations so that SL processes can be recovered and reused for new data transmissions. This allows the system to maintain data receiving reliability through proper MAC reset while recovering SL process resources for continued use.
2Productivity
If SL processes are released and association relationships are cleared, then data receiving rate is improved, but risk of incorrect data handling increases
Solution Approach 1:
The patent applies preliminary action by determining whether SL processes are unoccupied before releasing their association relationships. The system performs preliminary checks to identify SL processes that are not currently occupied with data transmissions, and only releases associations for these unoccupied processes. This preliminary identification ensures that active data transmissions are not interrupted while allowing resource release for improved data receiving rate, thereby maintaining reliability.
3Adaptability or versatility
If buffers of SL processes are cleared, then resource utilization is improved, but data transmission continuity may be affected
Solution Approach 1:
The patent applies local quality by selectively clearing buffers of specific SL processes based on their occupation status. Instead of clearing all SL process buffers uniformly, the system identifies and clears buffers only for unoccupied SL processes while preserving buffers for processes actively engaged in data transmissions. This localized approach improves resource utilization for available processes while maintaining data transmission continuity for active processes.

AI summary
This application relates to communications technology and provides methods and apparatuses for processing a sidelink process. In an implementation, a terminal device determines to perform media access control (MAC) reset on a radio resource control (RRC) connection of a sidelink and determines that a sidelink process associated with the RRC connection is unoccupied.
