METHOD FOR EXPANSIVELY TRANSMITTING CHANNEL ESTIMATION REFERENCE SIGNAL AND METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING CHANNEL ESTIMATION REFERENCE SIGNAL USING SAME
First Claim
1. A method of transmitting control information for expansive transmission of a channel estimation reference signal, the method comprising:
- determining, by a base station, a first user equipment, which was set to transmit a channel estimation reference signal in a first frequency band, to not transmit a channel estimation reference signal through the first frequency band;
generating first control information instructing a second user equipment to transmit a channel estimation reference signal in the first frequency band; and
transmitting a wireless signal including the generated first control information to the second user equipment.

Abstract
A method for transmitting control information to expansively transmit a channel estimation reference signal comprises the steps of: allowing a base station to determine not to transmit a channel estimation reference signal through a first frequency band, relative to a first user terminal which was set to transmit the channel estimation reference signal in the first frequency band; generating first control information which instructs a second user terminal to transmit the channel estimation reference signal in said first frequency band; and transmitting a wireless signal including said generated first control information to the second user terminal.
