Method, apparatus, and system for reporting power headroom in a mobile communication system

摘要

A method, apparatus, and system for efficiently reporting Power Headroom (PH) for optimizing uplink coverage are provided. A method in which user equipment reports power headroom in a mobile communication system includes receiving Power Headroom Report (PHR) configuration information including a PH threshold value from a first base station, determining whether to perform a PHR trigger by comparing the PH value, which indicates the available transmission power of the user equipment, with the PH threshold value, and, when the PH value is less than the PH threshold value, transmitting, to the first base station, PHR-related report information including information corresponding to an influence caused by the scheduling of the first base station.

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.
