1. A method performed by a terminal in a wireless communication system, the method comprising:
identifying that a procedure for providing a first base station with a power headroom report (PHR) is triggered;
identifying that a dual connectivity (DC) between the first base station and a second base station is configured for the terminal;
obtaining a value of type 1 power headroom (PH) for each activated serving cell for the first base station and the second base station;
identifying whether a radio access technology (RAT) of the second base station for the DC is an evolved-universal mobile telecommunications system (UMTS) terrestrial radio access (E-UTRA);
obtaining a value of type 2 PH for a serving cell of the second base station, in case that the identified RAT of the second base station for the DC is the E-UTRA;
generating the PHR including the obtained values of PHs for the first base station and the second base station; and
transmitting, to the first base station, the generated PHR.
