Abstract: A disclosure of the present specification provides a method for determining uplink transmission power by a wireless device. The transmission power determination method may comprise the steps of: determining whether transmission of uplink data uses 64 quadrature amplitude modulation (QAM) or not; determining whether transmission of the uplink data corresponds to multi-clustered transmission or not; determining whether transmission of the uplink data is to be performed through a single carrier or is to be performed through a plurality of carriers according to carrier aggregation; and determining a maximum power reduction (MPR) value, which is to be applied to transmission of the uplink data, according to the determination results. Here, when transmission of the uplink data uses the 64 QAM, corresponds to the multi-clustered transmission, and is performed through the single carrier, a first MPR value may be determined; and, when transmission of the uplink data uses the 64 QAM, corresponds to the multi-clustered transmission, and is performed through the plurality of carriers, a second MPR value may be determined.

Abstract: A disclosure of the present specification provides a method of measuring a neighboring small cell. The method may include the steps of: receiving measurement configuration information from a serving cell; and measuring on the serving cell, the neighboring small cell, and a neighboring macro cell. The measurement configuration information may include one or more of a discovery signal measurement timing configuration (DMTC) and a measurement gap (MG) for the neighboring small cell. In addition, the DMTC may include DMTC periodicity information and information on the occasion section of a discovery signal. When a frequency band in which the serving cell operates, a frequency band in which the neighboring small cell operates, and a frequency band in which the neighboring macro cell operates are all the same, a measurement on the neighboring small cell may be performed for the time section by the DMTC and a measurement on the serving cell may be performed for sections other than the time section by the DMTC.

Abstract: A disclosure of the present specification provides a terminal which uses a frequency band of a mobile satellite service for LTE/LTE-A. The terminal comprises: a first duplexer for separating a transmitted signal and a received signal in band 1 defined in long term evolution (LTE)/LTE-Advanced; a second duplexer for separating a transmitted signal and a received signal in new band 65 which was a mobile satellite service (MSS) band and now is allocated for the terrestrial service; and a selection switch for selecting one of the first duplexer and the second duplexer. Herein, when only band 1 is configured and used, only the first duplexer may be operated by the selection switch. In contrast, when new band 65 is configured and used, wherein the configured band does not overlap the range of band 1, and when new band 65 is configured and used, wherein the configured band overlaps the range of band 1 for carrier aggregation, only the second duplexer may be operated by the selection switch

Abstract: One disclosure of the present specification provides a method for performing measurement based on discovery signals. The method may comprise the steps of: receiving, from cells, discovery signals based on cell-specific reference signals (CRSs); and performing measurement based on the CRS-based discovery signals for a predetermined measurement period. If a measurement bandwidth is six resource blocks (RBs), the predetermined measurement period can be determined by 5*the measurement occasion periodicity of the discovery signals. If the measurement bandwidth is 25 resource blocks (RBs), the predetermined measurement period can be determined by 3*the measurement occasion periodicity of the discovery signals. Also, the discovery signals can be received for a discovery signal occasion duration defined by N consecutive subframes.

Abstract: One embodiment of the present specification provides a method for allocating resources to user equipment (UE) supporting 256 quadrature amplitude modulation (QAM) demodulation. The resource allocation method can comprise the steps of: receiving a channel quality information (CQI) report from the UE; determining, by the UE, whether a backoff of transmission power has been applied to a downlink subframe from which CQI is measured; determining whether the backoff of the transmission power is to be applied to the downlink subframe which is supposed to allocate the resources; and determining a modulation coding scheme (MCS) level on the basis of the CQI and the results of the determination.
