Base station and method for performing tdd base station uplink/downlink subframe configuration

Disclosed are a base station and a method for performing TDD base station uplink/downlink subframe configuration. The method comprises: determining a coupling loss between every two base stations of all base stations in a set area; performing clustering on the base stations in the set area according to the coupling loss between the base stations; and a base station performing TDD uplink/downlink subframe configuration according to a clustering result, base stations in a same cluster having to adopt the same TDD uplink/downlink subframe configuration, and base stations in different clusters adopting the same TDD uplink/downlink subframe configuration or different TDD uplink/downlink subframe configurations. The present invention is capable of reducing cross time slot interference brought by flexible subframe configuration of the TDD, and optimizing TDD network system performance.
