In this paper, three schemes based on the proportional fairness scheduling with power control are proposed for the virtual full-duplex (VFD) scheme by jointly considering the downlink (DL) and uplink (UL) UE pair selection and UL power control. In particular, the optimal scheme is derived via the exhaustive search for the UE pair and UL power. The second scheme reduces the complexity of the UE pair selection via choosing the DL UE and the UL UE separately, and the third scheme further reduces the UL power setting by reducing the candidate UL power levels. The simulation results verify that compared to the VFD scheme without power control, the largest spectral efficiency gain is obtained by the optimal scheme with the highest complexity, while the smallest spectral efficiency gain is achieved by the third scheme with the lowest complexity.
