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: A method and a base station for transmitting information for cell measurements, and a method and a user equipment for performing cell measurements are discussed. The method for transmitting information for cell measurements according to an embodiment includes transmitting, by the base station, information indicating a first time domain measurement resource restriction pattern for measurements of a first cell. The first time domain measurement resource restriction pattern indicates which subframe among subframes corresponding to the first time domain measurement resource restriction pattern is used for the measurements of the first cell. The first time domain measurement resource restriction pattern is configured such that a subset of non-almost blank subframes in an almost blank subframe pattern configured in the first cell is used for the measurements of the first cell. The almost blank subframe pattern indicates which subframes are configured as almost blank subframes or as the non-almost blank subframes.

Abstract: A method, performed by a user equipment (UE), is provided for determining uplink transmission power. A radio frequency (RF) unit is configured to use for an uplink transmission a frequency range of 1980 MHz through 2010 MHz or 1920 MHz through 2010 MHz. The UE receives a value of an additional maximum power reduction (A-MPR) from a serving base station (BS) adjacent to a neighboring BS for serving another UE using for an uplink transmission a frequency range of 2010 MHz through 2025 MHz. An uplink signal is transmitted at an uplink transmission power calculated by using the value of the A-MPR. The value of the A-MPR is 11 dB or 15 dB.

Abstract: A method of reducing transmission power. The method according to one embodiment includes calculating a maximum power reduction (MPR) on a maximum output power for transmission with non-contiguous resource allocation in a single component carrier; and transmitting a signal. The MPR is calculated differently depending on a ratio A which is a ratio of a number of simultaneously transmitted resource blocks in a channel bandwidth (NRB_alloc) to a number of aggregated resource blocks in a fully allocated aggregated channel bandwidth (NRB_agg). The MPR is calculated using a first equation when the ratio A is greater than 0 and less than or equal to 0.33. The MPR is calculated using a second equation when the ratio A is greater than 0.33 and less than or equal to 0.77. The MPR is calculated using a third equation when the ratio A is greater than 0.77 and less than or equal to 1.

Abstract: One embodiment of the present specification relates to a method for reducing transmission power. The method for reducing transmission power can comprise the steps of: determining whether set carrier aggregation (CA) corresponds to intra-band non-contiguous CA when the CA is set; determining transmission power by applying maximum power reduction (MPR) when the set CA corresponds to intra-band non-contiguous CA; and reducing power by applying additional MPR to the determined transmission power in order to protect adjacent bands when non-contiguous carriers belong to a specific band.
