    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).

    Abstract: A method of transmitting, by a transmitting device, an orthogonal frequency division multiplexing (OFDM) signal in a wireless communication system, the method including: generating, by a digital module of the transmitting device, a frequency-shifted OFDM baseband signal by performing frequency up-shift of a first signal by a difference between a carrier frequency f0 and a first frequency fbase, wherein the first frequency fbase is, among frequencies corresponding to integer multiples of 128Δf, closest to the carrier frequency f0, and wherein Δf is an OFDM subcarrier spacing; up-converting, by an analog oscillator of the transmitting device, the frequency-shifted OFDM baseband signal by the first frequency fbase to generate an OFDM symbol signal at the carrier frequency f0; and transmitting the OFDM symbol signal at the carrier frequency f0.

    Abstract: A method for receiving, by a base station, channel state information (CSI) in a wireless communication system. The method includes receiving, from a user equipment (UE), UE capability information related to at least one of channel state information-reference signal (CSI-RS) resources or CSI-RS ports; transmitting, to the UE, CSI-RS configuration information that includes information based on the UE capability information; transmitting, to the UE, a CSI-RS using at least one CSI-RS port based on the CSI-RS configuration information; and receiving, from the UE, the CSI, wherein the CSI is based on a measurement, for the CSI-RS, performed by the UE. Further, the UE capability information includes information for i) a maximum number of the CSI-RS resources and ii) a maximum number of the CSI-RS ports related to number of the CSI-RS resources configured based on the maximum number of the CSI-RS resources.
