Abstract:
A method and an apparatus for sending and receiving channel state information in network Multiple-Input Multiple-Output (MIMO) wireless communication systems are provided. Hybrid feedback technology is provided to transfer complete Channel State Information (CSI) to a transmitter by efficiently combining limited amounts of long-term channel information and short-term channel information are in a down link MIMO network system.
