Abstract: Embodiments of this application disclose an interference coordination method and an apparatus. The method includes: A first TDD system and a second TDD system are adjacent asynchronous TDD systems of each other, the first TDD system communicates with UE in a first slot by using a first specified frequency domain resource, and the second TDD system communicates with the UE in a second slot by using a second specified frequency domain resource, where the first specified frequency domain resource is different from the second specified frequency domain resource. Alternatively, the first TDD system modifies a slot configuration of a third slot corresponding to the first slot when communicating with the UE in the first slot, and the second TDD system modifies a slot configuration of a fourth slot corresponding to the second slot when communicating with the UE in the second slot. The first slot and the second slot have same time domain positions and different functions.
