    Abstract: One embodiment of the present specification provides a method by which a wireless device manages a buffer for performing soft combining. The method can comprise the steps of: decoding data received through device-to-device (D2D) communication; determining whether an error exists in the decoded data; determining whether a radio resource control (RRC) connection with a base station is established or/and a carrier aggregation is configured and activated if the error exists; taking at least one from among an instantaneous buffer to be used when the carrier aggregation is activated and a hybrid automatic repeat request (HARQ) buffer to be used when the RRC connection is established, on the basis of whether the RRC connection with the base station is established and whether the carrier aggregation is activated; and storing, in the taken one or more buffers, a soft bit for performing soft combining.

    Abstract: One disclosure of the present specification provides a method for receiving interference cancellation. The method for receiving interference cancellation can comprise: a step for cancelling, in signals received from a serving cell, cell-specific reference signals (CRS) from the serving cell, the CRS from a first primary interference cell, and the CRS from a second primary interference cell; a step for comparing the signal size of the serving cell, the signal size of the first primary interference cell, and the signal size of the second primary interference cell; a step for determining whether the CRS of the serving cell conflicts with the CRS of the first primary interference cell or the CRS of the second primary interference cell; and a step for canceling, when it is determined that the CRS' conflict with one other, data signals from the first primary interference cell and data signals from the second primary interference cell in the signals where the CRS are cancelled in the order determined according to the size comparison of signals.

    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.
