The upcoming 5G radio communication systems will be required to achieve as much as a thousand-fold throughput increase over current 4G systems. The increase is a huge challenge that needs to be addressed through different physical layer techniques such as the use of a massive number of antennas and of use of the centimeter- and millimeter-wave spectrum, among others. Still, it is likely that additional and more sophisticated transceiver technologies are required to increase the throughput further, and a technique that overlays these physical-layer techniques is required. In-band full-duplex technology can be complementary to other techniques and double the spectral efficiency , allowing the 5G networks to reach their full potential.
An in-band full-duplex-capable transceiver is able to transmit and receive simultaneously over the same center frequency . With this definition, ...
