A wireless transceiver and a relay station (RS) including the wireless transceiver, where the wireless transceiver includes multiple antennas; and multiple radio frequency (RF) chain pairs that are connected one-to-one to the antennas and each of which being able to be set to operate on both a downlink frequency and an uplink frequency or to operate only on one of the downlink frequency and the uplink frequency. Each of the RF chain pairs may be able to switch a transmission (Tx) frequency and a reception (Rx) frequency between the downlink frequency and the uplink frequency. For example, each of the RF chain pairs may include a first Tx/Rx band switch that is connected between a local oscillator pair and a mixer pair; and a second Tx/Rx band switch that is connected between an amplifier pair and a duplexer. |
