1. A method by a base station in a wireless communication system, the method comprising:
- transmitting configuration information including a prohibit power headroom report (PHR) timer for a PHR and information indicating whether a PHR format for a user equipment (UE) is an extended PHR to the UE; and
receiving the PHR corresponding to the PHR format from the UE,wherein the PHR is triggered at the UE, when the prohibit PHR timer is expired,wherein the received PHR is the extended PHR including a maximum transmission power generated based on a power management-maximum power reduction (P-MPR) and an indicator indicating whether the UE applies the P-MPR, if the PHR format for the UE is the extended PHR,wherein the received PHR is a normal PHR without the indicator if the PHR format for the UE is not the extended PHR, andwherein the indicator is set to 1 if the maximum transmission power included in the extended PHR is different from a maximum transmission power not applying a power back-off due to a power management.

Abstract
A method and an apparatus for efficiently transmitting or reporting a Power Headroom Report (PHR) of a User Equipment (UE) are provided. The method of transmitting the PHR of the UE in a mobile communication system includes configuring an extended PHR including an indicator corresponding to a variation factor of a maximum transmission power of the UE, and transmitting the extended PHR from the UE to a Base Station (BS). The BS may be notified of a maximum transmission power of the UE and a variation factor corresponding to the maximum transmission power in order to enable efficient scheduling.
