Dynamic Channel Access Parameter Selection for 5G Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current 5G mobile communications system uses a fixed channel access parameter for the same physical channel, resulting in low channel access flexibility, which can lead to signal delays and failures, especially for higher-priority services.
Innovation Solution
A method to determine a target channel access parameter based on service information, allowing for dynamic monitoring time lengths to improve channel access flexibility, enabling higher-priority services to preempt channel access more effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed channel access parameter is used for the same physical channel, then the system configuration is simple, but the channel access flexibility is low
Solution Approach 1:
The patent segments the channel access parameter configuration by dividing services into different priority levels (first priority, second priority, etc.). Each priority level has its own dedicated channel access parameter, allowing the system to select appropriate parameters based on service requirements. This segmentation enables flexible channel access while maintaining manageable system complexity through structured parameter organization.
Solution Approach 2:
The patent implements dynamic channel access parameter selection by allowing the terminal to choose different parameters based on the priority of the service being transmitted. Instead of using a fixed parameter for all services, the system dynamically adjusts the channel access parameter according to service priority, thereby improving channel access flexibility and responsiveness to different traffic requirements.
2Speed
If a fixed monitoring time length is used, then the channel access process is simple, but higher-priority services experience delays
Solution Approach 1:
The patent applies local quality by assigning different monitoring time lengths to different service priorities. High-priority services are allocated shorter monitoring time lengths to enable faster channel access, while lower-priority services use longer monitoring time lengths. This differentiated approach ensures that critical services experience minimal delay while maintaining overall system functionality.
Solution Approach 2:
The patent implements preliminary action by pre-configuring multiple channel access parameters with different monitoring time lengths before actual channel access occurs. The terminal selects the appropriate pre-configured parameter based on service priority, allowing high-priority services to immediately use optimized parameters without real-time calculation delays, thus reducing signal delay while maintaining access speed.

AI summary
The present disclosure provides a channel access method, a configuration method, a terminal, and a network side device. The channel access method applied to the terminal includes: determining, based on a mapping between service information and a channel access parameter, a target channel access parameter corresponding to first service information, where the first service information is service information triggering a first physical channel; and accessing the first physical channel based on the target channel access parameter.
