Abstract: A method is provided for transmitting network assistance information in a serving cell in order to perform interference cancellation of a terminal. The serving cell checks whether a traffic load of the serving cell is greater than or less than a first value, and whether a traffic load of a neighbor cell is greater than or less than a second value. The serving cell determines a target for which the interference cancellation is to be performed by the terminal, based on a result of the checking the traffic load of the serving cell and a result of the checking the traffic load of the neighbor cell. The serving cell transmits to the terminal the network assistance information including information regarding the determined target for which the interference cancellation is to be performed.

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: One embodiment of the present specification provides a reception method for a terminal supporting cooperative multi-point (CoMP). The reception method for the terminal may comprise the steps of: receiving a signal which indicates that a channel state indicator-reference signal (CSI-RS) port and a cell-specific reference signal (CRS) port are almost quasi co-located; and determining a frequency offset between a CRS and a demodulation-reference signal (DM-RS), which is quasi co-located with the CRS, on the basis of the signal which indicates that the CSI-RS port and the CRS port are almost quasi co-located. Herein the frequency offset between the CRS and the DM-RS may be within 50 Hz.

Abstract: The present invention relates to a method for measuring a location of a user equipment in a wireless access system for supporting carrier aggregation/multiple cells and an apparatus therefor. Specifically, the method comprises the steps of: enabling the user equipment to receive information on Positioning Reference Signal (PRS) transmission bandwidths of a reference cell and a neighboring cell, enabling the user equipment to reconfigure an operating channel bandwidth of a Radio Frequency (RF) unit when one of the PRS transmission bandwidth of the reference cell and the PRS transmission bandwidth of the neighboring cell belongs to an inactive secondary cell, enabling the user equipment to receive the PRS from the reference cell and the neighboring cell, and enabling the user equipment to measure a Reference Signal Time Difference (RSTD) by using the PRS of the reference cell and the PRS of the neighboring cell.

Abstract: One embodiment of the present specification provides an interference-removed reception method. The interference-removed reception method may comprise the steps of: encoding, in a binary in a physical channel, stored information for an attacker cell which causes interference; performing a comparison between the encoded binary and a new binary in the physical channel received from the attacker cell; and if the binaries match, removing interference caused by the new binary in the physical channel received from the attacker cell by using the encoded binary, and thereby receiving a signal from a serving cell.

Abstract: The present specification provides a method for performing measurements, by a terminal, in a coverage extension area of a small-scale cell in a wireless communication system in which macro cell and the small-scale cell coexist. The method for performing measurements can include the steps of: receiving information about a first subframe on which measurements for the small-scale cell can be performed and information about a second subframe on which measurements for the macro cell can be performed; when an interference cancellation function is set, measuring reference signal received power (RSRP) and a received signal strength indicator (RSSI) for the small-scale cell by driving the interference cancellation function on the first subframe; and measuring RSRP on the second subframe for the macro cell by driving the interference cancellation function and measuring the RSSI for the macro cell without driving the interference cancellation function.

Abstract: A disclosure of the present specification presents a method for executing measurement including: measuring a first and a second logical cell of a base station and measuring a cell of a neighboring base station; and executing cell reselection according to a result of the measuring or transmitting a measurement report including the result of the measuring to the base station. In the method, since the base station operates the first logical cell in a first sub-frame set within a wireless frame and operates the second logical cell in a second sub-frame set within the wireless frame to which power backoff is applied, the measuring of the first logical cell by the base station may be executed in the first sub-frame set and the measuring of the second logical cell by the base station may be executed in the second sub-frame set to which the power-back off is applied.

Abstract: The present disclosure provides a method of performing up-link transmission at a reduced power. According to the method, system information may be received from a base station. The system information may include one or more of first information on an operating band and second information on an up-link bandwidth.

Abstract: A method is provided for assisting measurement of a user equipment (UE). The method is performed by a serving cell for the UE. The serving cell determines whether a cell-specific reference signal (CRS) of the serving cell is to collide with a CRS of a second neighbor cell or whether a CRS of a first neighbor cell is not to collide with the CRS of the second neighbor cell, if the serving cell and the first neighbor cell correspond to aggressor cells to the second neighbor cell corresponding to a victim cell. The serving cell generates a second measurement subframe pattern based on an almost blank subframe (ABS) pattern in response to the determination, and transmits the second measurement subframe pattern for the first and second neighbor cells to the UE.
