Method of transmitting information about a pre-coding matrix of a terminal in a multiple node system

A first user equipment for transmitting precoding matrix information to a base station in a multi-node system, the first user equipment comprising:

• a radio frequency (RF) unit for transmitting and receiving a radio signal;
• and
• a processor connected to the RF unit, for controlling the RF unit,
• wherein the processor controls the RF unit to measure a downlink channel of a first node using a reference signal of the first node, measure a downlink channel of a second node using a reference signal of the second node, and transmit precoding matrix information for the first user equipment based on the measured downlink channel of the first node and the measured downlink channel of the second node.

A base station for receiving precoding matrix information from a first user equipment in a multi-node system, comprising:

• a radio frequency (RF) unit for transmitting and receiving radio signals;
• and
• a processor connected to the RF unit, for controlling the RF unit,
• wherein the processor controls the RF unit to transmit information on reference signals for demodulation transmitted by a second node to the first user equipment and to receive precoding matrix information from the first user equipment.
