A communication station (110) includes a transceiving circuit (113), a radio signal distribution circuit (115) and a control circuit (117). The radio signal distribution circuit (115) configures an antenna array (111) to communication with a communication device (120) with a first antenna port formation pattern (APFP) (210) and a second APFP (220) based on an elevation beamforming technique. The control circuit (117) configures the transceiving circuit (113) to generate a first reference signal and a second reference signal, and configures the radio signal distribution circuit (115) to configure the antenna array (111) to transmit the first reference signal and the second reference signal respectively with the first APFP (210) and the second APFP (220) to the communication device (120). The control circuit (117) further configures the transceiving circuit (113) 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 (115). |
