Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face inefficiencies in radio resource configuration, leading to increased call dropping and radio link failures, particularly due to inefficient configuration parameters received from base stations, which adversely affect spectral efficiency and signaling overhead.
Innovation Solution
A wireless device sends information to a base station, which comprises a distributed unit and a central unit, allowing the central unit to provide configuration parameters to the distributed unit for determining optimal configuration settings for the wireless device and other devices in the cell, thereby improving communication efficiency and power usage.

Engineering Contradiction Analysis
1Reliability
If the base station sends configuration parameters to wireless devices, then the wireless communication can be established and maintained, but the signaling overhead increases and spectral efficiency decreases
Solution Approach 1:
The patent changes the parameter transmission approach from downlink (base station to device) to uplink (device to base station). The wireless device autonomously determines configuration parameters based on its own measurements and capabilities, then reports only the determined parameters to the base station. This reduces the amount of data transmitted and eliminates the need for the base station to send extensive configuration parameter sets, thereby reducing signaling overhead and improving spectral efficiency while maintaining communication reliability.
2Ease of operation
If the base station provides configuration parameters to wireless devices, then the communication setup is simplified, but the device complexity and processing burden increase
Solution Approach 1:
The patent implements self-service by enabling the wireless device to autonomously determine its own configuration parameters based on its measurements, capabilities, and channel conditions. The device performs the configuration determination itself rather than relying on the base station to provide all parameters. This shifts the processing burden to the device but simplifies the overall system operation and reduces signaling overhead, as the device only needs to report the determined parameters rather than process extensive base station configurations.
3Extent of automation
If traditional configuration parameter transmission is used, then the base station maintains control over device configuration, but call dropping and radio link failures increase
Solution Approach 1:
The patent inverts the traditional configuration approach by having the wireless device determine configuration parameters autonomously rather than the base station controlling all configuration decisions. The device uses its own measurements and capabilities to determine optimal parameters, then reports them to the base station for confirmation. This inversion gives the device more autonomy to adapt to changing conditions, reducing call dropping and radio link failures while maintaining base station oversight through the reporting mechanism.
