The invention discloses an interference suppression method in a wireless cellular network, which comprises the following steps: when a second cellular user in active state suffers from the downlink interference of a first cellular base station around, the first cellular base station is notified that a second cellular user currently suffers from the downlink interference thereof; and the first cellular base station re-distributes the spectrum resources used by the first cellular user communicating therewith. The invention further discloses a first cellular base station, a second cellular user and a second cellular base station for implementing the interference suppression method. Through the invention, when a second cellular user in active state suffers from the downlink interference of a first cellular base station around, the first cellular base station can adjust the spectrum resources used by the first cellular user through resource scheduling, so as to reduce the downlink interference on the second cellul
