| abstract |
A method and system for transmitting and receiving data using a plurality of antennas are disclosed. The method of transmitting includes the steps of receiving at a transmitter (50) feedback information from a receiving end (55), wherein said feedback information includes channel quality information (CQI), antenna weight values, and antenna group selection information. The transmitter (50)comprises a switch unit (51) to group the plurality of transmitting antennas into a plurality of antenna groups according to the group selection information included in the feedback information. The data streams (52) are transmitted based on the weight values included in the feedback information to a receiving end (55) through the plurality of antenna groups, wherein each data stream is modulated and coded according to the channel quality information (CQI) in order to obtaimn a maximum data throughput. |
