Disclosed herein are systems, methods, and computer-readable storage devices for reducing inter-cellsite interference during full-duplex communication. A system receives a channel amplitude and a phase estimate between a first station and a second station, the first station and the second station creating inter-cellsite interference on a channel during full-duplex communications. The system calculates a level of the inter-cellsite interference between the first station and the second station based on the channel amplitude and the phase estimate and generates a cancellation signal based on the inter-cellsite interference. The system then communicates the cancellation signal to the first station for transmission with additional data during additional full-duplex communications.
