Title:
マルチセル協調送信方法
Document Type and Number:
Japanese Patent JP5484819
Kind Code:
B2
Abstract:
The present invention provides a cooperative multi-cell transmission method that can be utilized to implement cooperative transmission in a virtual cell. Sectors composing the virtual cell are real cells and/or full sectors in real cells, any sector among the sectors composing the virtual cell is physically located adjacent to at least one of the other sectors, and each sector of the virtual cell corresponds to a real transmitting node respectively. The method includes: acquiring channel state information between any user and at least one of real transmitting nodes by a main information processing node; performing user scheduling and real transmitting node scheduling based on the channel state information by the main information processing node; and cooperatively transmitting data of one or more scheduled users based on the channel state information by one or more scheduled real transmitting nodes. The method according to an embodiment of the present invention reduces the interference and enhances the system spectral efficiency.
