Patent ID: 8467339

Claim:
A cooperative multi-cell transmission method for implementing cooperative transmission in a virtual cell, wherein sectors composing the virtual cell are one or both of real cells and full sectors of real cells, and further wherein 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 cooperative multi-cell transmission method comprising: acquiring channel state information between any user and at least one of real transmitting nodes by the 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, wherein performing the user scheduling and real transmitting node scheduling based on the channel state information by the main information processing node comprises: determining all possible working mode combinations of the real transmitting nodes; determining a user scheduling result corresponding to each of the possible working mode combinations of the real transmitting nodes based on the channel state information between any user and at least one of the real transmitting nodes; calculating a system throughput or weighted throughput corresponding to each of the possible working mode combinations of the real transmitting nodes based on the channel state information between any user and at least one of the real transmitting nodes and the user scheduling result; and selecting one or more real transmitting nodes corresponding to the working mode combination of the real transmitting nodes with the maximum system throughput or weighted throughput as the scheduled real transmitting nodes, and making one or more users in the user scheduling result corresponding to the working mode combination of the real transmitting nodes with the maximum system throughput or weighted throughput as the scheduled users.
