TL;DR: In this paper, a method for reducing inter-cell interference in a wireless communication system according to one embodiment of the present invention is presented, where a first terminal receives, from a first cell, scheduling information for the transmission of a first signal to a second cell; and a step in which the first terminal transmits the first signal on the basis of the scheduling information.

TL;DR: In this paper, a method and apparatus for transmitting and receiving a CSI-Reference Signal (CSI-RS) in a wireless communication system supporting multiple antennas is described, which includes transmitting, at a base station, information of one or more CSI-RS configurations to a mobile station.

TL;DR: In this paper, the authors present a method and an apparatus for inter-cell interference coordination for a transmission point group, where one transmission group comprises a plurality of transmission points, and the interference coordination message can include interference coordination information about each individual transmission point unit within the one transmission point groups, and interference coordination about the overall transmission point units within the same group.

TL;DR: In this article, a method of reporting channel state information (CSI) on a terminal in which a plurality of CSI processes are configured in a wireless communication system according to an embodiment of the present invention includes: measuring a channel based on a CSI reference signal (RS) resource related to one of the CSI processes; measuring interference based on CSI-interference measurement (IM) resources related to the CSI process; determining CSI based on the measured channel and the measured interference; and reporting the CSI through an uplink channel.

TL;DR: In this article, a measurement method and apparatus for inter-cell interference coordination in a wireless communication system is described, which includes the steps of acquiring information of the downlink subframe configuration of a second base station, determining measurement objects of downlink resource of the first base station and transmitting information of measurement objects to the UE, and receiving measurement result for the measurement objects from the UE.
