Radio Parameter Detection Signaling Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of terminal device configurations in wireless communication networks leads to significant signaling overhead, particularly in 5G systems, due to the large number of radio parameters that need to be configured and managed, which affects cell throughput and latency.
Innovation Solution
A machine learning-based approach is employed where the terminal device reports its capability to detect radio parameters, allowing it to determine three sets of parameters: a first set completely, a second set with network assistance, and a third set during initial configuration or a predetermined time, following the behavior of the first and second sets, thereby reducing the need for extensive network configuration and signaling.

Engineering Contradiction Analysis
1Reliability
If the network configures all radio parameters explicitly, then the terminal device can accurately receive downlink channels, but the signaling overhead increases significantly
Solution Approach 1:
The patent segments radio parameters into three distinct sets: (1) parameters the terminal can determine completely autonomously, (2) parameters requiring network assistance information, and (3) parameters requiring full network configuration. This segmentation allows the network to configure only necessary parameters, reducing signaling overhead while maintaining reception accuracy.
Solution Approach 2:
The terminal device is empowered to autonomously determine the first set of radio parameters without any network assistance, and can determine the second set with minimal assistance information. This self-service capability reduces the burden on the network to configure all parameters explicitly, thereby reducing signaling overhead.
2Quantity of substance
If the terminal device autonomously determines all radio parameters, then the signaling overhead is reduced, but the complexity of parameter detection increases
Solution Approach 1:
By dividing radio parameters into three sets based on detection difficulty and network assistance requirements, the patent enables the terminal to handle autonomous detection for the first set (simpler parameters) while receiving assistance for the second and third sets (more complex parameters), thus balancing overhead reduction with detection feasibility.
Solution Approach 2:
The network provides assistance information and configurations in advance before the terminal needs to detect parameters. This preliminary action prepares the terminal with necessary reference data and constraints, making autonomous and assisted parameter detection more manageable and less complex.
3Measurement precision
If the network provides full configuration for all radio parameters, then the terminal can detect parameters accurately, but the configuration message size increases
Solution Approach 1:
The patent extracts and removes the first set of radio parameters from network configuration messages, as these can be autonomously determined by the terminal. Only the second and third sets requiring network assistance are included in configuration messages, significantly reducing their size while maintaining detection accuracy for all parameter sets.
Solution Approach 2:
Instead of providing complete configuration for all parameters (excessive action), the network provides partial configuration only for parameters that cannot be autonomously determined (second and third sets). This partial action is sufficient to achieve accurate parameter detection while minimizing configuration message size.
4Adaptability or versatility
If the terminal device reports detailed capability information, then the network can optimize configuration, but the initial signaling overhead increases
Solution Approach 1:
The capability report is segmented to include only relevant information about the terminal's ability to detect each of the three parameter sets. This structured segmentation allows the network to optimize configuration efficiently without requiring excessive detail, thus balancing adaptability with initial signaling overhead.
