PROBLEM TO BE SOLVED: To divide data in a wireless communication network.SOLUTION: In order to improve a bandwidth when UE is at a cell edge, data may be divided for the transmission thereof to the user equipment using a plurality of base stations, or in order to improve a handover, data may be divided for the transmission thereof to a plurality of base stations by the user equipment. The data division may be executed in a packet data convergence protocol layer, a radio link control layer or a media access control layer in the user equipment or each base station. In order to reduce an X2 interface load or X2 interface delay carrier aggregation, the data division may also be executed in place in a network node like a serving gateway. |
