Abstract: A joint transmission (JT) method and apparatus, the method including selecting, by a network device of a serving cell, a JT user equipment and a coordinated neighboring cell of the JT user equipment, sending, by the network device of the serving cell, a JT user equipment request to a network device of the coordinated neighboring cell, scheduling the JT user equipment and sending scheduling information to the network device of the coordinated neighboring cell, and sending, by the network device of the serving cell, a reference signal and data to the JT user equipment according to the scheduling information, where the reference signal sent by the network device to the JT user equipment by the network device of the serving cell is the same as a reference signal sent by the network device of the coordinated neighboring cell of the JT user equipment to the JT user equipment.

Abstract: A method for partitioning a communications network includes selecting, by a controller, a starting communications controller for a first region in the communications network according to an interference level. The method also includes including, by the controller, a first neighboring communications controller in the first region if an average inter-cell interference level of the starting communications controller and the first neighboring communications controller exceeds a first threshold and closing the first region if the average inter-cell interference level of the starting communications controller and the first neighboring communications controller fails to exceed the first threshold. The method further includes storing information about the first region in a memory.
