Abstract

Provided is a channel state information (CSI) sharing method and apparatus in a Multiple User Multiple Input Multiple Output (MU-MIMO) environment. Each node may use network-coding to reduce overhead necessary for sharing CSI between all nodes in the MU-MIMO environment. A transmitter may dynamically select, based on the CSI between receivers, a path used for transmitting data to each receiver and a receiver to be used as a relay based on the global CSI. A decoding performance may be improved based on the CSI between the transmitter and the receivers.
