Abstract: The present invention relates to a method of transmitting CSI-RS (channel state information-reference signal) configuration, which is transmitted by a base station in a wireless communication system, and an apparatus therefor. Specifically, the method includes the steps of composing an information element configuring a first CSI (channel state information) subframe set and a second CSI subframe set and transmitting the CSI-RS configuration including at least one or more ZP-CSI-RS configurations (zero power CSI-RS configuration). The CSI-RS configuration includes a first ZP-CSI-RS configuration for a first user equipment to which the information element is not set and a second user equipment to which the information element is set and a second ZP-CSI-RS configuration for the second user equipment only.

Abstract: A method and a first base station are described for setting measurement resources. Information about setting of a blank subframe of a second base station among a plurality of subframes is received. Resources are set in which a terminal will perform measurement using the information about setting of the blank subframe of the second base station. The information about setting of the blank subframe of the second base station includes a bitmap indicating blank subframes and non-blank subframes of the second base station. In addition, the resources in which the terminal will perform measurement are determined among the blank subframes indicated by the bitmap.

Abstract: A method for supporting measurement of a User Equipment (UE) by a first base station in a wireless communication system. The method according to an embodiment includes acquiring, by the first base station, information of a downlink subframe configuration of a second base station; and transmitting, by the first base station, information of measurement objects to the UE. The measurement objects are determined based on the downlink subframe configuration of the second base station. A measurement is performed by the UE in resources indicated based on the information of the measurement objects. The resources are determined as a combination of at least one Orthogonal Frequency Division Multiplexing (OFDM) symbol and at least one downlink subframe. The downlink subframe configuration of the second base station includes information indicating at least one subframe configured as an Almost Blank Subframe (ABS).
