User Equipment Channel Access Mode Selection via Priority Rules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in 5G technology on unlicensed spectra, user equipment faces challenges in determining the appropriate channel access mode when receiving multiple configuration settings from a network device.
Innovation Solution
The method involves a user equipment receiving at least two pieces of configuration information carrying channel access modes from a network device, determining first configuration information based on priorities or specific conditions, and selecting the channel access mode carried in that first configuration information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the user equipment receives multiple pieces of configuration information carrying channel access modes from the network device, then the channel access mode determination becomes more flexible and adaptable, but the complexity of determining the appropriate mode increases
Solution Approach 1:
The patent applies preliminary action by pre-defining priority relationships between different types of configuration information (e.g., RRC configuration vs. DCI configuration) before the user equipment needs to make a determination. This allows the UE to automatically resolve conflicts between multiple configuration information pieces without complex real-time decision-making, thus maintaining flexibility while reducing processing complexity.
Solution Approach 2:
The patent changes the parameter of configuration information validity based on priority rules. By assigning different validity statuses to configuration information from different sources (e.g., marking RRC configuration as valid only when not overridden), the system transforms the complex decision problem into a simpler parameter-based selection process, resolving the contradiction between adaptability and complexity.
2Reliability
If the user equipment performs comprehensive channel access mode determination based on multiple configuration information, then the communication reliability is improved, but the power consumption increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing priority rules and validity conditions for different configuration information types. This allows the user equipment to quickly determine the appropriate channel access mode through straightforward comparison rather than comprehensive analysis, reducing processing time and power consumption while maintaining communication reliability through the structured decision framework.
Solution Approach 2:
The patent extracts the essential decision-making logic from the complex set of configuration information by identifying the key priority relationships and validity conditions. This extraction allows the UE to focus only on the critical determination steps rather than processing all configuration details, thereby reducing power consumption while ensuring reliable communication through the most important configuration parameters.

AI summary
A method for determining a channel access mode is performed by a user equipment and includes: receiving, from a network device, at least two pieces of configuration information carrying channel access modes; determining first configuration information in the at least two pieces of configuration information based on the at least two pieces of configuration information; and determining that a channel access mode of the user equipment is a channel access mode carried in the first configuration information.
