Abstract :
In order to increase throughput and spectral efficiency in a heterogeneous network including a macro and a femtocell, we propose a combined offloading with In-Band Full Duplex (IBFD) scheme in this paper. Traffic offloading to the femtocell is deployed to transmit network users traffic to a macrocell base station in the uplink. In other words, all or a part of the traffic is offloaded to the femtocell and then transmitted to the macrocell, while the rest of traffic is transmitted to the macrocell directly. In the femtocell, we deploy and investigate IBFD technology, i.e., simultaneous transmit and receive traffic in one frequency band. Furthermore, in order to improve throughput of the network, we propose several scheduling schemes to transmit traffic. Finally, optimal number and position of users who use IBFD or do not use it, are determined. We propose a heuristic solution to find optimal position of IBFD users. Simulation results verify the network throughput improvement and power consumption reduction.
