1. A method of a terminal in a wireless communication system, the method comprising:
identifying that a medium access control (MAC) reset occurs;
if the MAC reset is performed, stopping a periodic power headroom report (PHR) timer;
receiving, from a base station, information related to an uplink resource;
identifying whether the uplink resource is first allocated for a new transmission since the MAC reset is performed;
when the uplink resource is first allocated for the new transmission since the MAC reset is performed, starting the stopped periodic PHR timer, even without transmitting a PHR;
triggering a PHR, if the started periodic PHR timer expires;
transmitting, to the base station, the triggered PHR ; and
starting the expired periodic PHR timer after triggering the PHR.
