A method for circumventing far-end interference, comprises: determining, (S101; S201), by an interfered station, that there is far-end interference preliminarily according to far-end interference features, and sending a first dedicated reference signal sequence to an interfering station; determining, (S102; S302), by the interfering station, that there is far-end interference according to the first dedicated reference signal sequence, and sending a second dedicated reference signal sequence to the interfered station; determining, (S103; S203), by the interfered station, that there is far-end interference finally according to the second dedicated reference signal sequence; circumventing, (S104; S204), by the interfered station and the interfering station, the far-end interference by adjusting a Guard Period, GP, length, in one of following ways: adjusting the GP length by adjusting a time slot format configuration according to distance information of a detected far-end interference source when a reference signal sequence is continuously detected within first preset time; wherein the distance information of the far-end interference source is determined according to a detection result of the far-end interference source within the first preset time; and detection result information of the far-end interference comprises a base station ID of the far-end interference source and a distance of the far-end interference source, or reporting detection result information of the far-end interference to a centralized control unit or an OAM; wherein the centralized control unit or the OAM determines a base station which needs to adjust the GP length according to the detection result information of the far-end interference and instructs the base station to adjust the GP length by adjusting a time slot format configuration. determining, (S101; S201), by an interfered station, that there is far-end interference preliminarily according to far-end interference features, and sending a first dedicated reference signal sequence to an interfering station; determining, (S102; S302), by the interfering station, that there is far-end interference according to the first dedicated reference signal sequence, and sending a second dedicated reference signal sequence to the interfered station; determining, (S103; S203), by the interfered station, that there is far-end interference finally according to the second dedicated reference signal sequence; circumventing, (S104; S204), by the interfered station and the interfering station, the far-end interference by adjusting a Guard Period, GP, length, in one of following ways: adjusting the GP length by adjusting a time slot format configuration according to distance information of a detected far-end interference source when a reference signal sequence is continuously detected within first preset time; wherein the distance information of the far-end interference source is determined according to a detection result of the far-end interference source within the first preset time; and detection result information of the far-end interference comprises a base station ID of the far-end interference source and a distance of the far-end interference source, or reporting detection result information of the far-end interference to a centralized control unit or an OAM; wherein the centralized control unit or the OAM determines a base station which needs to adjust the GP length according to the detection result information of the far-end interference and instructs the base station to adjust the GP length by adjusting a time slot format configuration. adjusting the GP length by adjusting a time slot format configuration according to distance information of a detected far-end interference source when a reference signal sequence is continuously detected within first preset time; wherein the distance information of the far-end interference source is determined according to a detection result of the far-end interference source within the first preset time; and detection result information of the far-end interference comprises a base station ID of the far-end interference source and a distance of the far-end interference source, or reporting detection result information of the far-end interference to a centralized control unit or an OAM; wherein the centralized control unit or the OAM determines a base station which needs to adjust the GP length according to the detection result information of the far-end interference and instructs the base station to adjust the GP length by adjusting a time slot format configuration.
