Method for reporting channel state information, method for supporting same, and apparatus for said methods

A method for transmitting, by an enhanced node B (eNB), CSI-RS in a wireless communication system, comprising:

• transmitting CSI-RS resource configuration information to a user equipment (UE);
• and
• transmitting the CSI-RS based on the CSI-RS resource configuration information to the UE,
• wherein the CSI-RS resource configuration information includes information on a CRS related to the CSI-RS, and
• the UE assumes that an antenna port associated with the information on the CRS and an antenna port used to transmit the CSI-RS corresponding to the resource configuration information on the CSI-RS are quasi-co-located.

A user equipment (UE) configured to receive a CSI-RS in a wireless communication system, comprising:

• a radio frequency (RF) unit;
• and
• a processor configured to control the RF unit,
• wherein the processor is configured to receive CSI-RS resource configuration information and to receive the CSI-RS based on the CSI-RS resource configuration information,
• wherein the CSI-RS resource configuration information includes information on a CRS related to the CSI-RS, and
• the UE assumes that an antenna port associated with the information on the CRS and an antenna port used to transmit the CSI-RS corresponding to the CSI-RS resource configuration information are quasi-co-located.

• an RF unit;
• and
• a processor configured to control the RF unit,
• wherein the processor is configured to transmit CSI-RS resource configuration information to a UE and to transmit the CSI-RS based on the CSI-RS resource configuration information to the UE,
• wherein the CSI-RS resource configuration information includes information on a CRS related to the CSI-RS, and
• the UE assumes that an antenna port associated with the information on the CRS and an antenna port used to transmit the CSI-RS corresponding to the CSI-RS resource configuration information are quasi-co-located.
