METHOD AND APPARATUS OF DATA TRANSMISSION BASED ON MULTI-CELL COOPERATION

摘要

PURPOSE: A method and an apparatus of transmitting data based on multi cell cooperation are provided to realize MU-MIMO(Multi-User Multiple-Input Multiple-Output) while reducing interference between terminals. CONSTITUTION: Information about adjacent cells participating in cooperative transmission is transmitted to a terminal(S410). Feedback information for selecting a beam forming mode for multi cell cooperation is received from a terminal(S420). The feedback information includes statistical information of exterior interference due to the adjacent cells. The beam forming mode about the terminal is selected based on the feedback information(S430). A base station informs the selected beam forming mode to the terminal(S440). Data to which a beam forming vector is applied is transmitted to the terminal(S450).
