ISWCS’19 – Workshop on Full Duplex Radio Communications for 5G and Beyond (FDB5G)
27 August 2019 @ 08:00 - 30 August 2019 @ 17:00
Full-duplex (FD) technology, by which devices transmit and receive simultaneously on the same frequency band, can potentially double the
spectral efficiency and allow a more flexible use of the spectrum, therefore making it a promising technology for future wireless networks. However, FD radios suffer from severe self-interference (SI), as well as extra cross interference between the uplink and downlink caused by simultaneous transmissions, which further degrades the overall network performance. To this end, many research groups around the world have proposed new transceiver designs, implemented advanced FD prototypes and have shown that SI can be suppressed almost down to the noise floor. Recently, some realistic field trials have already been completed in order to bring FD technology a step closer to practice. The impact of FD goes much beyond a simple factor of 2 increase in spectral efficiency. SI cancellation technology allows for simultaneous transmission and spectrum sensing which has a major impact on cognitive radio systems and on random access techniques.
This is e.g. being exploited by the Austin startup GenXComm which has shown impressive throughput gains in dense random access systems. Still there are many challenges and open problems in order to achieve the full potential of FD transmission. It is necessary to cope with the self-interference and develop new mechanisms and efficient protocols, while reducing the energy consumption due to the required additional hardware
