Abstract
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.
