Abstract: A communication station includes a transceiving circuit, a radio signal distribution circuit and a control circuit. The radio signal distribution circuit configures an antenna array to communication with a communication device with a first antenna port formation pattern (APFP) and a second APFP based on an elevation beamforming technique. The control circuit configures the transceiving circuit to generate a first reference signal and a second reference signal, and configures the radio signal distribution circuit to configure the antenna array to transmit the first reference signal and the second reference signal respectively with the first APFP and the second APFP to the communication device. The control circuit further configures the transceiving circuit to receive the first channel state information and the second channel state information respectively corresponding to the first reference signal and the second reference signal through the radio signal distribution circuit.
