Abstract
A mobile communication apparatus with an antenna array and a mobile communication method therefore, wherein the apparatus includes a base station with an antenna array and a mobile station, wherein the mobile station determines a channel downlink characteristic for each antenna, determines long-term information and short-term information, converts the determined long-term information and short-term information to a feedback signal, and transmits the feedback signal to the base station. The base station receives the feedback signal, extracts a plurality of weights from the long-term information and short-term information, multiplies a multiplexed dedicated physical channel signal by the respective weights, adds respective pilot channel signals to the products, and transmits the results of the additions through the antenna array to the mobile station. The present invention allows more users to use the same bandwidth through efficient feedback bandwidth utilization and maximized diversity and beamforming effects.
