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: 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.
