    • A mobile communication apparatus having an antenna array and a mobile communication method performed in the mobile communication apparatus, wherein the mobile communication apparatus includes a base station and mobile station, each having an antenna array. The mobile station measures the downlink characteristics of a channel for each antenna from a signal received from a base station, determines long-term information in which the correlation property of the channel for each antenna has been reflected from the measured downlink characteristics, transforms the long-term information into a feedback signal, and transmits the feedback signal to the base station. The base station receives the feedback signal, restores the long-term information from the received feedback signal, performs basis mapping and basis transformation on a dedicated physical channel signal using the restored long-term information, adds the basis-mapped and basis-transformed signal to each of pilot channel signals, and transmits the addition results to the mobile station.
