Abstract: One disclosure of the present specification provides a method for identifying a secondary cell on the basis of discovery signals. The method may comprise the step of receiving information on a discovery signal measurement timing configuration (DMTC) and a measurement cycle from a serving cell. The DMTC may include a DMTC periodicity. The measurement cycle may indicate the measurement cycle of an inactivated secondary cell (Scell) by subframe unit.

Abstract: The disclosure of the present invention proposes a method for transmitting a sidelink synchronization signal (SLSS). The method may be performed by a vehicle-to-vehicle (V2V) terminal and comprise: performing measurements during a predetermined evaluation time; determining whether values resulting from performing the measurements are below a threshold value; and if the values resulting from performing the measurements during the predetermined evaluation time are below the threshold value, transmitting the SLSS to a neighboring V2V terminal. If the V2V terminal is in radio resource control (RRC) idle state and if the V2V terminal is configured to use 1.28 s or 2.56 s of a discontinuous reception (DRX) cycle length, the V2V terminal may calculate the predetermined evaluation time by using the number of DRX cycles which is not greater than 3.

Abstract: One disclosure of the present specification provides an interference cancellation reception method. The interference cancellation reception method can comprise the steps of: cancelling an interference caused by a cell-specific reference signal (CRS) from a neighboring cell which is mixed within a signal received from a serving cell; blind-detecting a parameter related to a demodulation reference signal (DMRS) so as to discover whether the signal from the neighboring cell mixed within the received signal is a data channel modulated on the basis of the DMRS; cancelling an interference between the detected DMRS signal and a DMRS signal of the serving cell when the DMRS is detected on the basis of the DMRS-related parameter; blind-detecting a modulation order for the data channel from the neighboring cell; and receiving only the signal from the serving cell through the interference cancellation by the data channel from the neighboring cell on the basis of the modulation order.

Abstract: One embodiment of the present specification provides a method by which user equipment (UE) transmits an uplink signal according to a spectrum emission mask (SEM). The method comprises a step of transmitting the uplink signal on a plurality of carriers when an RF unit of the UE is set to use inter-band carrier aggregation. Here, when the frequency range of a first SEM of a first carrier overlaps the frequency range of a second SEM of a second carrier, any one SEM allowing a higher power spectral density (PSD) can be selected and applied.

More specifically, the present invention comprises the steps of: determining whether a cell-specific reference signal (CRS) that is inserted into a subframe of a pico cell, which corresponds to a multicast broadcast signal frequency network (MBSFN) almost blank subframe (ABS), overlaps with a CRS that is inserted into an MBSFN ABS of the macro cell, when the MBSFN ABS is transmitted from the macro cell; estimating the channel by using a CRS from the pico cell that remains after excluding the CRS that overlaps with the CRS of the macro cell; and decoding the channel which is received from the subframe of the pico cell by using a channel estimation value.
