1. A method for performing measurements, the method performed by a user equipment (UE) and comprising:receiving, by the UE, configuration information on a measurement gap,
wherein the UE is configured with a dual connectivity (DC) to an evolved universal terrestrial radio access (E-UTRA) cell and a new radio access technology (NR) cell,
wherein the configuration information on the measurement gap includes a measurement gap length (MGL),
wherein the MGL includes one of 3 ms, 4 ms and 6 ms,
determining a total number of slots to be interrupted during the MGL,
performing the measurement during the MGL
wherein the total number of slots to be interrupted is determined based on a subcarrier spacing (SCS) of the NR cell and the MGL.
