APPARATUS FOR TRANSMITTING AND RECEIVING DOWNLINK DATA IN WIRELESS COMMUNICATIONS SYSTEM SUPPORTING COOPERATION BETWEEN TRANSMISSION POINTS AND METHOD THEREFOR

摘要

Disclosed are an apparatus for transmitting and receiving a downlink data in a wireless communications system supporting cooperation between transmission points and a method therefor. A method for transmitting a downlink data in a wireless communications system includes the steps of: transmitting the information on resources management collection including the CSI-RS information for measuring the terminal received bower to a terminal; receiving a report of the received power measurement of the CSI-RS corresponding to the resources management collection from the terminal; determining the measurement collection including the CSI-RS information for the terminal to infer a channel based on the received power measurement report; and transmitting the resources mapped with data to the terminal based on the measurement collection.
