A Power Headroom Report (PHR) method and apparatus for a mobile communication system supporting carrier aggregation are provided. The method for transmitting PHR of a terminal in a mobile communication system includes configuring, when a PHR is triggered for at least one activated serving cell, an extended PHR for the at least one activated serving cell, the PHR being triggered when a change of a downlink path loss in the at least one activated serving cell is greater than a predetermined threshold value, and transmitting the extended PHR.
