Abstract:
Disclosed is method and apparatus for communication using common feedback information in multiple antenna system. According to this method, a receiving side device receives rank Ni signals from a transmitting side device with a first type multiple antenna transmission scheme at a first receiving opportunity, and receives rank Nj signals from the transmitting side device with a second type multiple antenna transmission scheme at a second receiving opportunity, where Ni>Nj. The feedback information of this method is common feedback information comprising a combination of a first feedback information for the rank Ni signals and a second feedback information for the rank Nj signals. For this, the first type multiple antenna transmission scheme uses the second type multiple antenna transmission scheme for transmission of rank Nj signals among the rank Ni signals received at the first receiving opportunity.
