OVER-THE-AIR TESTING OF AN ACTIVE ANTENNA SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240322917 titled 'OVER-THE-AIR TESTING OF AN ACTIVE ANTENNA SYSTEM
Simplified Explanation: The patent application describes mechanisms for over-the-air (OTA) testing of an Active Antenna System (AAS) of an End User Terminal (EUT) using beamforming techniques and time/frequency resource grids.
- Beamforming weights are applied to selected resource elements of the time/frequency resource grid to determine beam directions for different types of OTA testing configurations.
- Test signals are transmitted or received over the AAS using the time/frequency resource grid.
Key Features and Innovation:
- OTA testing of AAS of EUT using beamforming.
- Utilization of time/frequency resource grid for test signal transmission.
- Different beamforming weights for various OTA testing configurations.
Potential Applications:
- Telecommunications industry for testing AAS performance.
- Research and development of wireless communication technologies.
Problems Solved:
- Efficient and accurate testing of AAS.
- Optimization of beamforming for different testing scenarios.
Benefits:
- Improved testing accuracy.
- Enhanced performance evaluation of AAS.
- Streamlined OTA testing processes.
Commercial Applications: Potential commercial applications include:
- Telecommunications equipment manufacturers.
- Wireless network operators.
- Research institutions in the field of wireless communications.
Prior Art: Prior art related to this technology may include research papers on beamforming techniques in wireless communication testing.
Frequently Updated Research: Stay updated on advancements in beamforming technology for wireless communication testing to enhance OTA testing processes.
Questions about OTA Testing of AAS: 1. What are the key advantages of using beamforming in OTA testing of AAS? 2. How does the application of different beamforming weights improve the efficiency of OTA testing?
Original Abstract Submitted
there is provided mechanisms for ota testing of an aas of an eut. a method is performed by a network node. the method includes obtaining definition of a test signal to be transmitted or received by the eut in accordance with a time/frequency resource grid. the method includes applying first beamforming weights to first selected resource elements of the time/frequency resource grid that give first beam directions according to a first type of configuration for first ota testing of the aas. the method includes applying second beamforming weights to second selected resource elements of the time/frequency resource grid that give second beam directions according to a second type of configuration for second ota testing of the aas. the method includes initiating transmission or reception of the test signal over the aas using the time/frequency resource grid.
