Abstract
Provided are a mobile communication apparatus having multiple transmission antennas and multiple reception antennas and a mobile communication method performed in the mobile communication apparatus. In the apparatus a base station restores long-term and short-term information determined in consideration of first characteristics in a mobile station from a feedback signal received from the mobile station spatially processes dedicated physical channel signals using basis information produced from the restored long-term and short-term information and transmits the results of addition of the spatially-processed signals to pilot signals to the mobile station. The mobile station has at least one transmission antenna and the base station has at least one reception antenna. The first characteristics are the characteristics of the downlink channels of the respective transmission and reception antennas. Accordingly long-term and short-term information in which the downlink characteristics of a space channel has been reflected are fed back from the mobile station to the base station thus minimizing the effects of fading interference and noise and maximizing throughput.
