Abstract:
1. An apparatus for transmitting data using a millimeter wave channel, the apparatus comprising: a transmitter (TX) antenna module; a communication-capability-determination module which determines a communication capability of a receiver (RX) antenna module of a receiving station based on communication-capability data transmitted by the receiving station; an antenna-control module which controls the TX antenna module according to a beam-forming mode determined from among a plurality of beam-forming modes based on the communication capability of the RX antenna module and a communication capability of the TX antenna module; and a communication module which transmits data through the TX antenna module, wherein the beam-forming mode determines whether to transmit a TX antenna weight vector (AWV) pattern, whether to receive a feedback response pattern and whether to transmit an RX AWV pattern, and wherein the plurality of beam-forming modes comprises a first beam-forming mode determined when the TX antenna module includes a phased-array antenna, and a second beam-forming mode determined when the TX antenna module does not include the phased-array antenna.
