Abstract:This paper proposes a novel opportunistic full-duplex (FD) scheme switching among three duplex modes (DMs) of half duplex (HD), three node FD (TNFD) and bidirectional FD (BiFD) for the cellular systems. To this end, we first derive the conditions, by which one of the three DMs achieves larger average spectral efficiency (ASE) than the other two DMs. Specifically, we derive the minimum required self inteference (SI) cancellation factors of user equipments (UEs)/base station for BiFD/TNFD to achieve the highest … Show more
