An interference coordination method in TDD systems, an apparatus, and a system are disclosed in embodiments of this invention, which relate to the communication field. A interfered cell may distinguish uplink-downlink interference based on the uplink-downlink configuration of the interfering cell, and send the uplink-downlink interference indication information to the interfering cell, so that interference coordination can be performed on uplink-downlink interference by the interfering cell. The method provided in the embodiment of this invention comprises: receiving by an interfered cell a uplink-downlink configuration of an interfering cell sent from the interfering cell; generating by the interfered cell interference indication information for subframes in the interfered cell in a direction opposite to the signal transmission direction in the interfering cell, according to a uplink-downlink configuration of the interfered cell and the uplink-downlink configuration of the interfering cell; sending by the interfered cell the uplink-downlink configuration of the interfered cell and the interference indication information to the interfering cell, to enable the interfering cell to perform interference coordination according to the uplink-downlink configuration of the interfered cell and the interference indication information. |
