RRC Inactive Measurement Reporting for Faster 5G Network Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G NR networks, the transition of user equipment from an RRC inactive state to a connected state for network configuration delays the initial transmission rate of data services, leading to suboptimal user experience due to inefficient network configuration processes.
Innovation Solution
User equipment in the RRC inactive state determines a valid measurement result and sends an RRC connection message carrying a measurement configuration parameter to the serving base station, allowing network configuration without transitioning to the RRC connected state, thereby reducing signaling overheads and service delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network side device sends a second indication information to indicate that the first cell is a primary cell, then the user equipment can correctly identify the primary cell for PUCCH transmission, but the signaling overhead increases and the configuration process becomes more complex
Solution Approach 1:
The patent extracts the essential identification function from the complex cell configuration process. Instead of using comprehensive second indication information to mark primary cells, the invention uses the existing first indication information (which already identifies the primary cell through its transmission characteristics) as the key identifier. This extraction simplifies the configuration while maintaining reliability.
Solution Approach 2:
The first indication information serves dual purposes: it identifies the primary cell for PUCCH transmission and simultaneously provides the necessary configuration parameters. The system uses the existing indication information's transmission characteristics (time resources, frequency resources) as the identification basis, allowing the indication information to self-identify the primary cell without requiring additional separate marking mechanisms.
2Adaptability or versatility
If the network side device configures multiple cells with similar parameters, then the network can achieve load balancing and traffic offloading, but the user equipment cannot distinguish which cell should be used for PUCCH transmission
Solution Approach 1:
The patent applies local quality by making the first indication information cell-specific in its transmission characteristics. Each cell has unique time resources and frequency resources allocated for its indication information transmission. This local differentiation allows the user equipment to distinguish between multiple cells with similar configuration parameters by detecting which cell's indication information is transmitted in which time-frequency resource, enabling both load balancing and clear cell identification.
3Ease of manufacture
If the user equipment uses existing indication information to identify the primary cell, then the configuration process is simplified, but the network side device cannot flexibly control which cell the user equipment uses for PUCCH transmission
Solution Approach 1:
The patent implements dynamics by making the first indication information configurable and adjustable. The network side device can dynamically modify the time resources and frequency resources allocated for transmitting the first indication information based on real-time network conditions. This dynamic adjustment allows the network to flexibly control which cell the user equipment identifies as the primary cell for PUCCH transmission, while the user equipment simply needs to detect the transmitted indication information to identify the cell, maintaining configuration simplicity.

AI summary
This application relates to the field of communication technologies, to resolve a problem that an initial transmission rate is low when a network device performs network configuration, and provides a network configuration method, user equipment, a network device, and a computer storage medium. The network configuration method is applied to user equipment, and the user equipment is in a radio resource control RRC inactive state. The network configuration method includes: obtaining a measurement result for a camped cell; determining that the measurement result is valid; and sending an RRC connection message to a serving base station, where the RRC connection message is used to request to set up an RRC connection between the user equipment and the serving base station. The RRC connection message carries a measurement configuration parameter, and the measurement configuration parameter is used to indicate the serving base station to complete network configuration.
