METHOD FOR TRANSMITTING POWER HEADROOM REPORT IN NETWORK SUPPORTING INTERWORKINGS BETWEEN MULTIPLE COMMUNICATION SYSTEMS, AND APPARATUS THEREFOR

摘要

A method for a terminal in a first communication system to transmit a power headroom report in a network supporting interworking of a plurality of communication systems comprises a step for transmitting a power headroom report comprising a power headroom value related to a second communication system, when a predetermined triggering condition occurs in a state in which the terminal is accessing the first and second communication systems simultaneously, wherein the power headroom report can comprise information regarding maximum transmission power for the second communication system.
