Abstract
There is provided mechanisms for OTA calibration of an AAS. The AAS comprises N antenna branches, each of which comprises a respective subarray. The subarray of each antenna branch gives rise to a subarray antenna pattern extending over an angular interval. A method is performed by a test equipment. The method comprises obtaining measurement values for each of the antenna branches. At least one measurement value is obtained per each antenna branch. The method comprises determining one calibration factor value per antenna branch using the measurement values and taking the subarray antenna patterns into account. The method comprises applying the determined calibration factor values to the N antenna branches, thereby calibrating the AAS.
