Abstract: An approach is described to for new radio (NR) antenna test function (ATF) measurements by a user equipment (UE). The approach includes measuring a first average phase of receive signals on resource elements that carry secondary synchronization signals (SS) received by a reference individual receiver branch. The approach also includes measuring a second average phase of the receive signals on the resource elements that carry secondary synchronization signals received by one other individual receiver branch different from the reference individual receiver branch. The approach further includes determining a difference between the first average phase and the second average phase. An indication of the difference is reported to test equipment.
