5G communication systems are expected to have 1000 times larger capacity using denser base station, wider communication bandwidth and higher spectral efficiency. Together with millimeter-wave communications, in-band full duplex radio system is one of potential solutions. In-band full duplex radio, which is often called STAR (simultaneous transmit and receive) system can achieve twice higher spectral efficiency theoretically. Generally, the in-band full duplex system is considered impossible due to the strong interference from its own transmitting power (self-interference), and therefore the self-interference cancellation (SIC) is the key aspect of the in-band full duplex system. This talk presents recent research aimed at the self-interference cancellation especially at antenna and RF domain, and its closed loop system to control the RF SIC circuits.
