Method for adaptive formation of cell clusters for cellular wireless networks with coordinated transmission and reception

摘要

The present invention provides a method of forming clusters of cells in a wireless communication system. The method includes accessing information generated by measuring channel conditions for at least one mobile unit and a plurality of cells in the wireless communication system. The method also includes adding more than one of the plurality of cells to at least one cell cluster based on the accessed information and coordinating communication between the cells in each cell cluster and the mobile unit(s).

1. A method of forming clusters of cells in a wireless communication system, comprising:
accessing information generated by measuring a plurality of channel conditions for at least one mobile unit and a plurality of cells in the wireless communication system; adding more than one of the plurality of cells to at least one cell cluster based on the accessed information; establishing at least one interface to exchange information between the cells in said at least one cell cluster; synchronizing communication between the cells in said at least one cell cluster and said at least one mobile unit using timing reference signals transmitted between the cells over said at least one interface; and updating the cells in the at least one cell cluster by establishing or tearing down interfaces between pairs of cells based on measured values of channel conditions, wherein said updates are performed on a time scale determined by a coherence distance of multipath fading in the wireless communication system.
