    Abstract: A disclosure of the present specification provides a method for performing measurement by a terminal which can establish dual connectivity to a first network system and a second network. The method may comprise the steps of: receiving, from a first cell of the first network system, first information relating to a synchronization signal block for a connection to a second cell of a second network system; measuring a time difference between a timing of the first cell and a timing of the second cell; transmitting information on the time difference to the first cell; receiving, from the first cell, second information updated for the synchronization signal block of the first information; and re-configuring a measurement gap for receiving the synchronization signal block on the basis of the second information.

    Abstract: One disclosure of the present specification provides a measurement method. The measurement method comprises the steps of: performing a reference signal received power (RSRP) measurement on the basis of a synchronization signal block (SSB), which is received from a serving cell; performing a received signal strength indicator (RSSI) measurement by using a reference signal, which is received in a bandwidth part (BWP), when a frequency band of the SSB is not included in the BWP, which is set for a terminal; and determining reference symbol received quality (RSRQ) on the basis of the results of the performed RSRP measurement and the performed RSSI measurement.

    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 embodiment of the present invention provides a method for a vehicle-to-everything (V2X) communication terminal applying an on/off power time mask. The method may comprise the step of applying an on/off power time mask in a case where a primary sidelink synchronization signal (PSSS), a secondary sidelink synchronization signal (SSSS) and a physical broadcast channel (PSBCH) are transmitted from one subframe. Here, the on/off time mask may designate an observation period between an SSSS symbol and an adjacent PSSS symbol in the subframe. Power for the PSSS may be turned off at 20 microseconds (μs) before the start of a first SSSS symbol in the subframe. Further, power for the SSSS may be turned on at 20 μs after before the start of the first SSSS symbol in the subframe.

    Abstract: One embodiment of the present specification provides a method by which a wireless device manages a buffer for performing soft combining. The method can comprise the steps of: decoding data received through device-to-device (D2D) communication; determining whether an error exists in the decoded data; determining whether a radio resource control (RRC) connection with a base station is established or/and a carrier aggregation is configured and activated if the error exists; taking at least one from among an instantaneous buffer to be used when the carrier aggregation is activated and a hybrid automatic repeat request (HARQ) buffer to be used when the RRC connection is established, on the basis of whether the RRC connection with the base station is established and whether the carrier aggregation is activated; and storing, in the taken one or more buffers, a soft bit for performing soft combining.
