AI Technical Summary

Technical Problem

Existing technologies fail to effectively manage resource conflicts and collisions between Long Term Evolution (LTE) and New Radio (NR) Side-Link (SL) transmissions on the same channel, necessitating a solution to guarantee high-priority service transmission and avoid resource collisions.

Method used

A method and apparatus for SL resource preemption on the same channel, involving a resource allocation flow based on information from both LTE and NR wireless access modules to determine and preempt resources, reducing collisions and ensuring system performance.

Benefits of technology

The method reduces resource collisions and ensures system performance by executing a resource allocation flow and preemption based on occupied or permitted resources, enhancing transmission efficiency in LTE and NR SL systems.

Abstract

The present invention provides a side-link SL resource preemption method, apparatus, and storage medium in the same channel, the method comprising: executing a resource allocation flow based on first information of a first radio access module of a first terminal and second information of a second radio access module to determine a first resource set; and performing resource preemption based on the first resource set and the second resource set, wherein the second resource set is determined based on resources currently occupied or permitted by the transmission of the first radio access module of the first terminal.
