1  Scopep. 7

The objectives for FR2-1 OTA testing for UEs with multi-panel reception and 4DL layer are as follows:
  • Define a test methodology for RF/RRM/Demodulation requirements testing for devices that can receive simultaneously from multiple Angle of Arrival (AoA).
  • The multiple AoA test setup should enable testing of up to 2 DL Layers with dual polarization for each angle;
    • For RRM, the target should be to allow testing of 4 AoAs with 2 simultaneously active AoAs .
    • Define a test methodology for up to 4 DL MIMO layer demodulation testing.
  • Smartphone form factor should be the first priority, other UE types should also be discussed as 2nd priority
  • Develop the related preliminary uncertainty assessments for the test methodologies
  • The tests shall take the test system reuse, test system complexity and test time into account to keep the whole test costs within a reasonable level.
