“…The authors in [17]- [19] proposed a hybrid-duplex scheme for HetNets by utilizing tools from the stochastic geometry and analyzed signal-to-interferenceplus-noise ratio (SINR) distribution, area spectral efficiency (ASE), achievable rate and throughput for both DL and Uplink (UL) channels and have shown that Hybrid-duplex scheme outperforms both pure-HD and pure-FD HetNets. In another research direction [20]- [22], the investigations of energy efficiency (EE) and local delay are conducted in conventional HetNets by considering HD mode for all links. However, these methods are inefficient for FD/Hybrid systems due to the SI and suffered interference from the FD users on the receiver of interest.…”

Heterogeneous networks (HetNets) as a combination of macro cells and small cells are used to increase the cellular network's capacity, and present a perfect solution for highspeed communications. Increasing area spectrum efficiency and capacity of HetNets largely depends on the high speed of backhaul links. One effective way which is currently utilized in HetNets is the use of full-duplex (FD) technology that potentially doubles the spectral efficiency without the need for additional spectrum. On the other hand, one of the most critical network design requirements is delay, which is a key representation of the quality of service (QoS) in modern cellular networks. In this paper, by utilizing tools from the stochastic geometry, we analyze the local delay for downlink (DL) channel, which is typically defined as the mean number of required time slots for a successful communication. Given imperfect self-interference (SI) cancellation in practical FD communications, we utilize duplex mode (half-duplex (HD) or FD) for each user based on the distance from its serving base station (BS). Further, we aim to investigate the energy efficiency (EE) for both duplexing modes, i.e., HD and FD, by considering local delay. We conduct extensive simulations to validate system performance in terms of local delay versus different system key parameters.
