Fig. 12From: 3GPP 3D MIMO channel model: a holistic implementation guideline for open source simulation toolsAntenna array port virtualization applied on system-level for co-pol and cross-pol polarization modes. The antenna ports are denoted as p i with i∈{1,…,4}. The parameters ω q , q∈{1,…,Q} are the phase shifts for static beamforming (e.g., electrical downtilting)Back to article page
