Disclosed in the present application are a method, system and device for circumventing far-end interference, which are used to better circumvent far-end interference by means of flexibly adjusting a GP length. The method for circumventing far-end interference provided by the present application includes an interference-receiving station preliminarily determining that there is far-end interference according to far-end interference features, and sending a first dedicated reference signal sequence to an interfering station; the interfering station determining that there is far-end interference according to the first dedicated reference signal sequence, and sending a second dedicated reference signal sequence to the interference-receiving station; the interference-receiving station finally determining that there is far-end interference according to the second dedicated reference signal sequence; and the interference-receiving station and the interfering station circumventing the far-end interference by means of adjusting the GP length.
