Disclosed are a communication device and a space division duplex method therefor. The communication device comprises at least one first channel, at least one second channel, and at least two antennas which are mutually independent of the first channel and the second channel. The method comprises the steps of: acquiring channel state information between a communication device and an opposite end; according to the channel state information, selecting from the antennas a first antenna corresponding to the first channel and a second antenna corresponding to the second channel; connecting the first channel with the first antenna, and connecting the second channel with the second antenna; and at the same moment and the same frequency resource, using the first channel and the first antenna connected thereto to transmit a signal and the second channel and the second antenna connected thereto to receive the signal, or using the first channel and the first antenna connected thereto to receive the signal and the second channel and the second antenna connected thereto to transmit the signal. |
