Abstract: One embodiment of the present invention provides a method for a wireless device determining transmission power. The method may comprise the steps of: when asynchronous dual transmissions for vehicle-to-everything (V2X) and a cellular uplink are set, and when a subframe p for cellular uplink transmission and a subframe q for V2X transmission mutually overlap, determining whether the subframe p for cellular uplink transmission precedes the subframe q for V2X transmission; and on the basis of the decision, determining a reference subframe from among the subframe p and the subframe q. Here, the reference subframe may be used for determining the lower limit of a transmission power.

Abstract: One disclosure of the present specification provides a channel estimation method of a user equipment (UE). The method comprising: acquiring a first channel estimate based on a first reference signal allocated to a first resource element of a subframe received from a base station; and removing a second reference signal from a second resource element of the subframe when an additional reference signal is not required, and decoding a data channel multiplexed in the second resource element using a result of channel estimation of an entire channel performed based on the first channel estimate. The second reference signal and the data channel may be multiplexed in the second resource element.

Abstract: A disclosure of the present specification provides a method for performing measurements. The method may performed by a user equipment (UE) comprise: performing, by the UE, measurements; based on that (i) the measurements are for measuring a cross link interference (CLI) and (ii) that the measurements are performed on a sounding reference signal (SRS) from a neighboring UE in a neighboring cell, adjusting a time error between a downlink reference timing in a serving cell and a SRS arrival timing from the neighboring UE. The adjustment is performed based on offset.

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: A disclosure of the present specification provides a method for performing measurement in a wireless device having a plurality of radio frequency (RF) chains for supporting aggregation of multiple carriers. The method may comprise the steps of: receiving, from a base station, information including measurement configuration (MeasConfig) information that includes a measurement gap (MG) for performing inter-frequency measurement; when the number of the received measurement gaps is one, determining, among the multiple carriers, a carrier corresponding to the RF chain to which the one measurement gap is to be applied; and transmitting, to the base station, a measurement report including the result of performing inter-frequency measurement by applying the measurement gap to the RF chain for the determined carrier. When the number of the received measurement gaps is one, the measurement report may include an indication of the carrier to which the measurement gap has been applied.

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.
