Sinr Analysis Of Heterogeneous Networks With Hybrid Duplex

In this paper, we propose a novel distance-based hybrid-duplex scheme for heterogeneous networks (HetNets). Assuming each user can select half-or full-duplex mode based on the transmit distance to its serving base station (BS), we derive uplink signal-to-interference-plus-noise-ratio (SINR) and spectral efficiency using stochastic geometry. Our results demonstrate that the proposed distance-based hybrid-duplex HetNet can achieve higher spectral efficiency over a wide range of self-interference cancellation (SIC) capability, while the full-duplex mode only outperforms than the half-duplex HetNet for high SIC capability.
