Predictive Wireless Configuration via Assisting Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless networks lack effective procedures or techniques for configuring wireless nodes to make predictive measurements that can be used to optimize future communication configurations, leading to suboptimal performance due to reactive changes in response to changing channel conditions.
Innovation Solution
A control node receives assisting information from other wireless nodes, which includes measurements taken over a wireless channel. Based on this assisting information, the control node determines a communication configuration to accommodate changes in channel conditions, optimizing future communication settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless networks use reactive configuration changes based on current channel conditions, then the system maintains simplicity in operation, but network performance deteriorates due to obsolete configurations when conditions change rapidly
Solution Approach 1:
The system performs preliminary actions by having wireless nodes make predictive measurements of channel conditions before actual communication occurs. The control node receives assisting information containing these predictive measurements and determines communication configurations in advance, so that when communication happens, the configuration is already optimized for the expected channel conditions rather than being reactive to potentially obsolete measurements.
2Productivity
If wireless networks implement predictive measurements and configuration optimization, then network performance improves by anticipating channel changes, but system complexity increases due to additional measurement and processing requirements
Solution Approach 1:
The system segments the predictive measurement function into separate wireless nodes that perform measurements and report to a control node. This division allows the complexity of predictive measurements to be distributed across multiple nodes rather than concentrated in one complex system, while still achieving optimized network performance through centralized configuration determination.
Solution Approach 2:
The control node acts as an intermediary that receives assisting information containing predictive measurements from wireless nodes and processes this information to determine optimized communication configurations. This intermediary structure simplifies the overall system by centralizing the complex processing logic in the control node while keeping individual wireless nodes relatively simple measurement and reporting units.
3Adaptability or versatility
If wireless nodes make frequent configuration changes to adapt to rapidly changing channel conditions, then adaptability improves, but latency increases due to the time required for measurement, assessment, and reconfiguration
Solution Approach 1:
The system performs configuration determination in advance based on predictive measurements, so that when communication needs to occur, the configuration is already optimized and ready to use. This eliminates the latency associated with real-time measurement and reconfiguration, as the predictive approach anticipates channel conditions beforehand and prepares appropriate configurations proactively.

AI summary
Aspects for predicting communication configurations for a wireless node are provided. Assisting information is measured or assessed at a first wireless node. The assisting information may include clutter and blocker measurements, self-interference measurements, and various beam, frequency, and modulation-related measurements. A control node may determine a communication configuration based on the assisting information. The communication configuration may be predicted for use at a subsequent time period. The first wireless node may receive and approve the configuration. The first wireless node may use the communication configuration in a subsequent communication with a second wireless node. The communication configuration may include, for example, whether the first wireless node will communicate using a full-duplex or half-duplex configuration and the TX/RX beam configuration for the node.
