Antenna Panel Selection Using Vehicle-to-Vehicle Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems with multiple antenna panels, the sending vehicle device cannot determine which panel is suitable for improving data transmission coverage with a receiving vehicle device.
Innovation Solution
A method involving a sending vehicle device sending control signaling with a source identifier to instruct a receiving vehicle device to measure its antenna panels, and selecting an appropriate panel based on the reported measurement results.

1Area of stationary object
If multiple antenna panels are provided at different positions with different directions, then coverage is improved, but the ability to determine the suitable panel for data transmission is lost
Solution Approach 1:
The receiving vehicle device measures the antenna panels of the sending vehicle device and reports the measurement results back to the sending vehicle device. This feedback mechanism enables the sending vehicle device to determine which antenna panel is suitable for data transmission based on the reported measurement information, thereby resolving the panel selection problem while maintaining multiple panels for coverage improvement
Solution Approach 2:
The receiving vehicle device performs preliminary measurement of the antenna panels before actual data transmission. By measuring and reporting the antenna panel characteristics in advance, the sending vehicle device can select the appropriate panel for subsequent communication, avoiding the need for real-time determination during data transmission

AI summary
A method and an apparatus for selecting an antenna panel. A sending vehicle device: sends a first control signaling. The first control signaling includes a sending source identifier and is configured to instruct a receiving vehicle device to measure antenna panels of the sending vehicle device identified by the second source identifier. The receiving vehicle device measures the antenna panels of the sending vehicle device according to the first control signaling, and reports an antenna panel measurement result. The sending vehicle device receives the antenna panel measurement result and selects a suitable antenna panel according to the antenna panel measurement result.
