A SIC-Based BS Coordination Scheme for Full Duplex Cellular Networks

Full Duplex (FD) in cellular networks is expected to increase the cell spectral efficiency. However, while downlink (DL) efficiency (SE) increases with FD, uplink (UL) SE decreases because of Base Station (BS) interference. In this paper, assuming a three-node model, we propose method based on Successive Interference Cancellation (SIC) reduce BS-to-BS interference present FD networks. The approach consists coordinating BSs enable decoding and suppression undesired signals that impair transmissions. We analyze both distributed Centralized Radio Access Networks (CRAN) architectures. Stochastic geometry used derive coverage probability mean data rate proposed scheme. scenario, UL average increased by 25% our solution compared classical network, scheme still outperforms Half-Duplex (HD) DL. centralized HD 10% 78% UL, preserving gains
