Abstract
An apparatus and method for transmitting packet data through at least two transmit antennas in a packet data communication system using transmit antenna diversity. In the packet transmitting apparatus, a feedback information interpreter interprets feedback information including CQIs and antenna weights received from a plurality of UEs requesting a packet data service. A weight generator classifies the antenna weights and selects UEs having orthogonal weights. A transmitter applies the selected weights to packet data destined for the selected UEs and transmits the packet data to the selected UEs simultaneously.
