<p>The present application discloses a communication apparatus and a space division duplex method thereon The communication apparatus includes at least one first chain, at least one second chain, and at least two antennas that are mutually independent of the first chain and the second chain. The method includes the following steps: obtaining channel state information between the communication apparatus and a peer end; selecting, according to the channel state information and from the antennas, a first antenna corresponding to the first chain and a second antenna corresponding to the second chain; connecting the first chain to the first antenna, and connecting the second chain to the second antenna; and at a same time-frequency resource, transmitting a signal by using the first chain and the first antenna connected to the first chain and receiving a signal by using the second chain and the second antenna connected to the second chain, or receiving a signal by using the first chain and the first antenna connected to the first chain and transmitting a signal by using the second chain and the second antenna connected to the second chain.</p> |
