Abstract: A disclosure of the present specification provides a method for selecting a cell for which to perform interference cancellation. The method may comprise the steps of: measuring reception power on the basis of reference signals received from neighboring cells; measuring the reception power of a data channel received from a serving cell; selecting a candidate cell among the neighboring cells by comparing the reception power of the data channel from the serving cell with the reception power from the neighboring cells; performing blind detection only for the candidate cell; measuring the reception power of a data channel from the neighboring cell on the basis of the blind detection; and when the reception power of the data channel from the neighboring cell is larger by at least a threshold than the reception power of the data channel from the serving cell, selecting the candidate channel as a cell for which to perform interference cancellation.

Abstract: A disclosure of the present specification provides a method for receiving a sidelink synchronisation signal (SLSS) for proximity service (ProSe). The method may comprise the steps of: receiving an SLSS from a neighbouring ProSe UE; and measuring a reference signal received power (RSRP) of the SLSS during a pre-determined measurement period. The measurement step can be executed assuming that the SLSS transmission from the neighbouring ProSe UE during the measurement period is not abandoned more than once. The measurement period can be extended if the SLSS transmission from the neighbouring ProSe UE is abandoned more than once.

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: There is provided a method for reducing transmission power. The method may be performed by a vehicle-to-everything (V2X) communication device and comprise: deriving a value of maximum power reduction (MPR); determining a transmission power by using the value of the MPR; and transmitting signals at the determined transmission power. If the signals are a physical sidelink control channel (PSCCH) signal and physical sidelink shared channel (PSSCH) signal and if simultaneous transmissions of the PSCCH signal and the PSSCH signal is configured, the value of the the MPR may be equal to or less than 1.5 dB or 2 dB.

Abstract: Disclosed is a method by which a terminal sets a resource pool for device-to-device communication in a wireless communication system. Particularly, the method comprises the steps of: acquiring information on a scheduling assignment (SA) resource pool through a synchronization step with a specific terminal; detecting a resource allocation SA in the SA resource pool; receiving a first D2D data channel including a resource pool allocation message on the basis of the resource allocation SA; and setting a resource pool for a second D2D data channel including user data and/or a resource pool for a discovery signal, according to the resource pool allocation message.

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.
