Random Access Mode Selection for Multi-Modal 5G Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing random access methods in wireless communication networks are inefficient for multi-modal communications, leading to increased delays and errors due to the use of inappropriate access modes, particularly in 5G and beyond networks.
Innovation Solution
A method and apparatus that allow a base station to send indication information to a terminal to select an appropriate random access mode based on specific conditions, such as communication type and signal strength, ensuring the random access procedure meets the requirements of the initiated multi-modal service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If four-step random access procedure is used, then reliability is improved, but communication delay increases
Solution Approach 1:
The patent implements dynamic random access mode selection where the terminal adapts between four-step and two-step random access procedures based on real-time conditions such as signal strength and service requirements. This dynamic adjustment allows the system to optimize between reliability and delay by choosing the appropriate mode for each specific scenario, rather than being fixed to one procedure.
2Loss of time
If two-step random access procedure is used, then communication delay is reduced, but reliability deteriorates
Solution Approach 1:
The patent changes the operational parameters of the random access procedure by introducing mode selection based on signal strength thresholds and service type parameters. When signal strength exceeds a threshold and the service is delay-sensitive, the system switches to two-step procedure to reduce delay. When conditions favor stability, it uses four-step procedure to ensure reliability, thus optimizing performance through parameter adjustment.
3Device complexity
If fixed random access mode is used, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The terminal performs self-service by autonomously selecting the appropriate random access mode based on its own assessment of signal strength and service requirements. The system includes self-evaluation mechanisms that compare current conditions against predefined thresholds and automatically adjust the random access procedure without requiring complex network-side control or configuration, thus maintaining low device complexity while achieving high adaptability.

AI summary
A base station in a wireless communication network sends indication information to a terminal or user equipment. The indication information is configured to indicate that the terminal should perform a random access procedure in a target mode when an initiated multi-modal communication or service meets a target condition. The terminal receives the indication information, determines according to the indication information, a target mode for performing random access procedure when an initiated multi-modal communication or service meets a target condition; and performs random access procedure in the target mode when the initiated multi-modal communication or service meets the target condition.
