METHOD AND APPARATUS FOR TRANSMITTING IN WIRELESS COMMUNICATION SYSTEM

摘要

In a transmission device in a wireless communication system based on a multi-cell comprised of a plurality of sub-cells, the present invention includes: a transmitter transmitting a signal by a sub-cell to the plurality of sub-cells through a plurality of antennas; a receiver receiving uplink control information from at least one terminal located in at least one sub-sell of the plurality of sub-cells; and a controller determining a virtual matrix for each of the plurality of sub-cells, controlling selecting a pre-coding matrix according to the determined virtual matrix, determining transmission mode based on the received uplink control information, and controlling the transmitter to perform downlink transmission by a sub-cell through antennas designated through the virtual matrix according to the determined transmission mode.
