摘要

The uplink spectrum of cellular networks is often underutilized due to the asymmetric behavior of wireless data services. To enhance the efficiency, a full-duplex (FD) cellular system is proposed to reuse the uplink spectrum for concurrent uplink and downlink transmissions. By jointly designing transmit beamforming and power control, a weighted sum-interference power minimization problem is formulated for downlink users to manage the self- interference and multiuser interference with the guaranteed QoS of uplink users. An iterative joint transmit beamforming and power control (TB-PC) algorithm is then proposed to solve the joint design problem based on the dual decomposition. The performance is validated by computer simulation, and the proposed FD scheme can potentially improve the spectrum efficiency when a small serving cell is considered for downlink users, as compared with the conventional half- duplex scheme.
