Mobile communication system

摘要

The present invention relates to a mobile communication system having a coordinated communication mode in which radio communication is performed between a user equipment and a plurality of base stations in a coordinated manner and an uncoordinated communication mode in which radio communication is performed between a user equipment and a base station without coordinating with another base station, in which radio communication is performed by selectively using any of the coordinated communication mode and the uncoordinated communication mode. The coordinated communication in which radio communication is performed between a user equipment and a plurality of base stations in a coordinated manner and the uncoordinated communication in which radio communication is performed between a user equipment and a base station without coordinating with another base station are selectively used in an appropriate manner, with the result that a mobile communication system capable of exerting its performance in accordance with a situation can be provided.

主权项

1. A mobile communication system comprising:
a plurality of base stations; and a user equipment which has a coordinated communication mode, in which radio communication is performed between a user equipment and a plurality of base stations in a coordinated manner such that the same data is transmitted or received simultaneously over a separate channel between the user equipment and each of the plurality of base stations, and an uncoordinated communication mode in which radio communication is performed between a user equipment and a base station without coordinating with another base station, wherein radio communication is performed by selectively using any of said coordinated communication mode and said uncoordinated communication mode.
