The invention provides a relative-narrowband-TX-power (RNTP)-based interference suppression method in a long-term evolution (LTE) system. The method comprises the following steps that: in an RNTP period, each base station selects an X% subcarrier with the lowest max{min(tau j')} from all subcarriers as an edge subcarrier; each base station informs another base station adjacent to the base station of not using the edge subcarrier selected by the base station through an RNTP signaling; and when clients are scheduled, each base station schedules a client with a lowest signal-to-interference-to noise-ratio onto the edge subcarrier selected by the base station. Due to the method, an effect of suppressing the interference can be greatly improved.
