Abstract: One disclosure of the present specification provides a method for simultaneously transmitting, by user equipment (UE), a cellular uplink signal and a proximity service (ProSe) signal. The method may comprise a step of determining the total transmission power PCMAX of the cellular uplink signal and the ProSe signal. Here, the total transmission power PCMAX may satisfy PCMAX_L≤PCMAX≤PCMAX_H. At this time, PCMAX_L may be a lower limit value and PCMAX_H may be an upper limit value. The cellular uplink signal is transmitted in a subframe n, the ProSe signal is transmitted in a subframe m, and subframe n may be considered as a reference subframe if subframe n and subframe m are time asynchronous.

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: Provided is a method for performing measurement by a user equipment (UE). The method may include receiving, by the UE, configuration information on a measurement gap. The UE may be configured with a dual connectivity (DC) to an evolved universal terrestrial radio access (E-UTRA) cell and a new radio access technology (NR) cell. The configuration information on the measurement gap may include a measurement gap length (MGL). The MGL may include one of 3 ms, 4 ms and 6 ms. The method may include determining a total number of slots to be interrupted during the MGL, and performing the measurement during the MGL. The total number of slots to be interrupted may be determined based on a subcarrier spacing (SCS) of the NR cell and the MGL

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: 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.
