1. A method performed by a master evolved universal terrestrial radio access network (E-UTRAN) node B (MeNB) in a wireless communication system, the method comprising:
receiving, from a user equipment (UE), capability information including first information on a number of radio frequency (RF) chains supported by the UE, second information on whether the UE supports a measurement gap per cell group or per serving cell, and third information on at least one frequency for which the measurement gap is required;
transmitting, to a secondary next generation node B (SgNB) for a new radio (NR), an SgNB addition request message for an E-UTRAN NR dual connectivity (EN DC), wherein the SgNB addition request message includes the capability information including the first information, the second information and the third information;
receiving, from the SgNB for the NR, an SgNB addition request acknowledge message as a response to the SgNB addition request message, wherein the SgNB addition request acknowledge message includes information on at least one first measurement gap which is based on the first information, the second information and the third information;
transmitting, to the UE, a radio resource control (RRC) connection reconfiguration message including the information on the at least one first measurement gap;
in case that a measurement gap indication timer is running and a measurement for the at least one frequency using the at least one first measurement gap is not supported by the UE, receiving, from the UE, an RRC connection reconfiguration complete message including an indication for requesting at least one second measurement gap for the at least one frequency; and
in case that the measurement gap indication timer expires and the measurement for the at least one frequency using the at least one first measurement gap is not supported by the UE, receiving, from the UE, a capability message including the indication for requesting the at least one second measurement gap for the at least one frequency.
