Abstract
In a radio communication system performing radio communications using multiple antenna ports, a radio base station apparatus transmits a reference signal from each of the antenna ports in multiple patterns corresponding to a plurality of antenna port configurations formed of single antenna elements or groups of antenna elements, and determines the antenna elements that form the respective antenna ports based upon feedback information supplied from a mobile device that has received the reference signal in the multiple patterns.
