In_Band full duplex deployment in heterogeneous cellular networks

Abstract

In order to imitate the frequency spectrum shortage problem and improve the cellular network coverage in high density areas, In-Band Full Duplex (IBFD) deployment in a heterogeneous network is proposed in this paper. IBFD, the technology of simultaneously transmitting and receiving in one frequency band, combined with a scheduling scheme are applied to a femtocell which acts as a relay to upload the traffic of a high density area to a macrocell. Numerical evaluation of the proposed scheduling scheme shows that the scheme increases the network throughput up to two times when self-interference of IBFD is low.
