摘要：A mobile communication apparatus with an antenna array and a mobile
communication method therefore, wherein the apparatus includes a base station with anantenna array and a mobile station, wherein the mobile station determines a channeldownlink characteristic for each antenna, determines long-term information and short-term information, converts the determined long-term information and short-terminformation 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 thelong-term information and short-term information, multiplies a multiplexed dedicatedphysical channel signal by the respective weights, adds respective pilot channel signals tothe products, and transmits the results of the additions through the antenna array to themobile station. The present invention allows more users to use the same bandwidththrough efficient feedback bandwidth utilization and maximized diversity andbeamforming effects.
