Millimeter-Wave Full Duplex Radios: New Challenges and Techniques

Equipping millimeter-wave (mmWave) systems with full duplex capability would accelerate and transform next-generation wireless applications forge a path for new ones. Full mmWave transceivers could capitalize on the already attractive features of communication by supplying spectral efficiency gains latency improvements while also affording future networks deployment solutions in form interference management backhaul. Foreseeable challenges obstacles making reality are presented this article along noteworthy unknowns warranting further investigation. With these novelties mind, we lay out potential - beyond active self-interference cancellation that harness spatial degrees freedom bestowed dense antenna arrays to enable simultaneous transmission reception in-band.
