1. A base station system comprising:
multiple antenna arrangements, each of the antenna arrangements having an array antenna where multiple antenna elements are two-dimensionally or three-dimensionally arranged, wherein each of the multiple antenna elements is a dual or multi polarized antenna element; and
a base station logic coupled to the multiple antenna arrangements,
wherein the base station logic is configured to control at least one of the multiple the antenna arrangements to:
transmit, to one or more user equipments, at least one first downlink signal using a first polarization, at least one second downlink signal using a second polarization, and at least one third downlink signal using a third polarization, wherein each one of the at least one first downlink signal, the at least one second downlink signal, and the at least one third downlink signal carries a corresponding unique identifier, and
receive, from the one or more user equipments, the corresponding unique identifier associated to at least one of the at least one first, second, and third downlink signals,
wherein the first polarization, the second polarization, and the third polarization are different from each other.
