Claim Text:
1. A communication device, comprising: a beamforming link generating unit which generates a first beamforming link between a first antenna of a plurality of antennas of the communication device and an external device, and which is able to generate a second beamforming link between a second antenna of the plurality of antennas of the communication device and the external device; and a transmission/reception unit which transmits data to the external device via each of the first beamforming link and the second beamforming link, and which is able to receive data, wherein the transmission/reception unit comprises: a frame transmitting unit which transmits a sweep frame to the external device via each of a plurality of sectors, wherein each of the plurality of sectors corresponds to a respective one of the plurality of antennas; and a frame receiving unit which receives a feedback frame from the external device, wherein the beamforming link generating unit determines the first antenna and one of the plurality of sectors which corresponds to the first antenna and the second antenna and one of the plurality of sectors which corresponds to the second antenna based on information relating to the received feedback frame, and wherein the beamforming link generating unit generates the first beamforming link using the determined first antenna and the determined sector corresponding to the first antenna, and generates the second beamforming link using the determined second antenna and the determined sector corresponding to the second antenna.
