Mobile communication apparatus with antenna array and mobile coomunication method therefor

摘要

A mobile communication apparatus with an antenna array and a mobile communication method therefore are provided. A mobile communication apparatus includes a base station with an antenna array and a mobile station, wherein the mobile station which determines a channel downlink characteristic for each antenna using a signal transmitted from the base station, determines long-term information and short-term information based on the correlation of characteristics between channels for each antenna, using the channel downlink characteristic, converts the determined long-term information and short-term information to a feedback signal, and transmits the feedback signal to the base station, and the base station which receives the feedback signal, extracts a plurality of weights from the long-term information and short-term information restored from the received feedback signal, multiplies a multiplexed dedicate 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. <IMAGE>
