Abstract:
1. A method of performing data communication through a transceiver using multiple antennas, the method comprising the steps of: determining a data service type of a received signal in a higher layer; generating higher layer information including the data service type, and transmitting the higher layer information to an antenna selection device; selecting at least one antenna corresponding to the data service type included in the higher layer information the multiple antennas among; and employing the selected at least one antenna to perform data communication of the data service type, wherein the antenna selection device performs an antenna selection algorithm to allot a weight factor for each antenna element according to the higher layer information, thereby selecting the at least one antenna having a large weight factor obtained from a predetermined lookup table, the look up table mappings a weight factor and a communication quality of an antenna corresponding to each data service type provided by a base station to a subscriber terminal.
