This paper proposes novel buffer-aided relaying selection in a two-hop cooperative network based on virtual full-duplex (VFD) and half-duplex transmission. The proposed scheme consists of five relay selection modes, i.e., two unicast modes, a broadcast mode, a cooperative beamforming mode, and a VFD mode. The broadcast mode allows multiple relay nodes to seamlessly share a common packet, which allows us to solve the inter-relay interference problem imposed on the VFD mode.
