Terminal Radio Resource Selection for Low-Latency Conflict Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio resource scheduling methods in wireless communication systems face issues such as long user-plane delay, resource wastage, and resource conflicts, particularly in scenarios with varying cell coverage and frequency bands.
Innovation Solution
Terminal devices are enabled to autonomously determine radio resource selection using machine learning models, allowing them to acquire resources without additional delay, while network devices can schedule resources to avoid conflicts and wastage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If radio resources are scheduled for terminal devices, then resource allocation can be controlled, but user-plane delay increases
Solution Approach 1:
The terminal device autonomously selects radio resources for data transmission without requiring network scheduling. The terminal determines whether to perform autonomous resource selection and selects resources from available resource pools, eliminating the need for scheduling requests and grant communications, thus reducing user-plane delay while maintaining controlled resource allocation through autonomous decision-making
2Loss of time
If terminal devices autonomously select radio resources, then user-plane delay is reduced, but resource conflicts may occur
Solution Approach 1:
The terminal device dynamically determines whether to perform autonomous resource selection based on current communication conditions. The system adapts between autonomous selection mode (for low delay requirements) and network-scheduled mode (for conflict-prone scenarios), allowing flexible adjustment of resource allocation strategy according to real-time needs and environmental conditions
Solution Approach 2:
The terminal device receives feedback from the network regarding resource selection performance and communication conditions. Based on this feedback, the terminal adjusts its autonomous resource selection behavior, learning from past experiences to improve resource selection decisions and reduce conflicts while maintaining low latency
3Reliability
If radio resources are scheduled by network, then resource conflicts are avoided, but resource wastage occurs
Solution Approach 1:
The terminal device autonomously selects radio resources from available resource pools based on its own data transmission needs and channel conditions. This self-service approach allows the terminal to request and use exactly the resources it needs without requiring network scheduling overhead, eliminating resource wastage associated with scheduled allocations that may not be fully utilized
4Productivity
If terminal devices autonomously select radio resources, then resource allocation efficiency improves, but device complexity increases
Solution Approach 1:
The terminal device implements autonomous resource selection functionality that enables it to independently determine and select radio resources without network intervention. This self-service capability improves resource allocation efficiency by eliminating scheduling delays and overhead, while the terminal's own intelligence handles the selection complexity internally

AI summary
A communication method, a terminal device, and a communication device are provided. The method includes the following. A terminal device determines whether to autonomously perform radio resource selection; and in a case where the terminal device autonomously performs radio resource selection, the terminal device transmits data and/or buffer data information based on a first radio resource autonomously selected by the terminal device. Based on the disclosure, whether to autonomously perform radio resource selection is determined by the terminal device itself. In some cases, the terminal device may determine to autonomously perform radio resource selection, allowing the terminal device to acquire a resource(s) for data transmission without introducing additional delay. In some cases, the terminal device may determine not to autonomously perform radio resource selection, and a scheduler may schedule the terminal device to allocate a radio resource(s) dedicated to the terminal device, thereby avoiding resource conflicts or resource wastage.
