Abstract
The invention discloses a base station and a method of configuring TDD uplink-downlink subframes for base stations, and the method includes: determining a coupling loss between every two of base stations in a preset region; clustering the base stations in the preset region according to the coupling loss between every two of the base stations; and the base stations configuring TDD uplink-downlink subframes according to results of clustering, wherein the base stations in the same cluster are configured with the same TDD uplink-downlink subframe configuration, and the base stations in different clusters are configured with the same TDD uplink-downlink subframe configuration or different TDD uplink-downlink subframe configurations. The invention can lower interference across time slots due to flexible configuration of TDD subframes and optimize the performance of a TDD network system.
