    Abstract: One disclosure of the present specification provides a terminal for transmitting and receiving a signal, the terminal supporting dual connectivity between E-UTRA and NR. The terminal comprises: a transceiver for transmitting an uplink signal and receiving a downlink signal by using the dual connectivity; and a processor for controlling the transceiver, wherein the transceiver is configured to use two of E-UTRA operating bands 1, 3, 18, 21, 28, 41, and 42 and NR operating band n79, and when an uplink center frequency of a first operating band among the E-UTRA operating bands and the NR operating band n79 is a first value and a downlink center frequency of the first operating band is a second value, an MSD is preset, and on the basis of a dual uplink operation, the MSD may be applied to reference sensitivity used for receiving the downlink signal.

    Abstract: A disclosure of the present specification provides a method for measuring an interference from a neighboring device. The method may performed by a device and comprise: measuring, by the device, an interference based on a reference signal from a neighboring device, which is served by a neighboring cell; and transmitting, by the device, a measurement report to a serving cell, the measurement report including a measured value of the interference. One or more steps of measuring the interference and transmitting the measurement report may be performed based on configuration information. The configuration information includes one or more of start information, end information, a timer or a threshold.

    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 a relay that supports a time division duplex (TDD) operation for temporally multiplexing a first link, which is either an uplink or downlink, and a second link, which is different from the first link. The method comprises: receiving, by the relay, a first radio signal through a first reception antenna for the first link; limiting, by the relay, an amplification rate of a first transmission antenna for the first link or an amplification rate of a second transmission antenna for the second link, based on an amplitude of the first radio signal; and relaying, by the relay, the first radio signal through the first transmission antenna without decoding the first radio signal if the amplification rate of the second transmission antenna is limited.
