Abstract: One embodiment of the present specification provides a method by which a user equipment (UE) reports channel quality. According to the method, the UE can receive a channel state information-interference measurement (CSI-IM) configuration of first and second transmission points (TPs). Here, the CSI-IM configuration includes at least three configurations for the CSI-IM, and the at least three configurations for CSI-IM can include a first CSI-IM configuration for measuring interference to the first TP caused by the second TP, a second CSI-IM configuration for measuring interference to the second TP caused by the first TP, and a third CSI-IM configuration for measuring interference from other interference sources. Therefore, according to the channel quality reporting method, the UE can feed a channel quality indicator (CQI) measured using the first CSI-IM configuration and a CQI measured using the third CSI-IM configuration back to the first TP.

Abstract: With increasing user requirements for social networking services (SNS), communication between user equipments (UEs) at a physically close distance, i.e., device to device (D2D) communication, is needed. D2D communication is performed on the basis of the discovery between UEs. However, D2D communication between UEs may cause interference to communication with an existing system, i.e., a base station. Thus, one aspect of the present invention provides a user equipment comprising a transceiver capable of removing self-interference.
