An antenna system includes at least a first antenna processing unit, APU1, and a second antenna processing unit, APU2, adjacently connected to each other through a serialized front haul. Each one of the APU1 and APU2 has at least two antenna elements. The antenna elements of APU1 are connected to their respective Radio Frequency, RF, chains via a first beamforming unit, and the antenna elements of APU2 are connected to their respective RF chains via a second beamforming unit. A network node configures the first beamforming unit and the second beamforming unit such that an absolute value of an angular difference between at least one of the beam directions generated by the first beamforming unit and each of the beam directions generated by the second beamforming unit exceeds or is equal to a threshold value.
A method performed by a network node for configuring an antenna system of the network node, which antenna system comprises at least a first antenna processing unit, APU1, and a second antenna processing unit, APU2, adjacently connected to each other through a serialised front haul, and each one of the APU1 and APU2 comprising at least two antenna elements,
A non-transitory computer storage medium storing a computer program comprising instructions, which when executed by a processor, causes the processor to perform method for configuring an antenna system of a network node, which antenna system comprises at least a first antenna processing unit, APU1, and a second antenna processing unit, APU2, adjacently connected to each other through a serialised front haul, and each one of the APU1 and APU2 comprising at least two antenna elements, the antenna elements of APU1 being connected to their respective Radio Frequency, RF, chains via a first beamforming unit, and the antenna elements of APU2 being connected to their respective RF chains via a second beamforming unit, the method comprising:
A network node for configuring an antenna system of the network node, which antenna system comprises at least a first antenna processing unit, APU1, and a second antenna processing unit, APU2, adjacently connectable to each other through a serialised front haul, and each one of the APU1 and APU2 comprising at least two antenna elements, the antenna elements of APU1 being connectable to their respective Radio Frequency, RF, chains via a first beamforming unit, and the antenna elements of APU2 being connectable to their respective RF chains via a second beamforming unit, the network node configured to:
