Abstract:
1. A method for reporting Power Headroom (PH) by a User Equipment (UE) in a mobile communication system, the method comprising: receiving Power Headroom Report (PHR) configuration information including a PH threshold from a first base station; determining whether to perform a PHR trigger by comparing a PH value indicating available transmit power of the UE with the PH threshold; and when the PH value is less than the PH threshold, transmitting PHR-related report information, including information corresponding to an influence caused by scheduling of the first base station, to the first base station, wherein whether to perform the PHR trigger is determined by using at least one of a number of Resource Blocks (RBs) allocated to the UE and a Modulation and Coding Scheme (MCS) level by scheduling of the first base station.
