Abstract
A mobile communication apparatus with multiple transmission and reception antennas and a mobile communication method therefor are provided. In the mobile communication apparatus including a base station and a mobile station, the base station with at least one transmission antenna restores long-term information, short-term information, a signal to interference and noise ratio (SINR) from a feedback signal received from the mobile station, spatially processes dedicated physical channel (DPCH) signals using basis information generated from the restored long-term information, short-term information, and SINR, and transmits the results of adding pilot channel (PICH) signals to the spatially processed results to the mobile station. The mobile station with at least one reception antenna determines a first characteristic corresponding to the channel downlink characteristic for each of the transmission and reception antennas, from the PICH signals transmitted from the base station, determines the long-term information, the short-term information, and downlink power control information including the SINR, which reflect the first characteristic, converts the determined long-term information, …
