METHOD OF EFFICIENTLY REPORTING USER EQUIPMENT TRANSMISSION POWER AND APPARATUS THEREOF

摘要

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.

1. A method for receiving a power headroom report (PHR) by a base station (BS) in a mobile communication system, the method comprising:
transmitting configuration information including a periodic PHR timer for the PHR to a user equipment (UE); and receiving the PHR including an indicator associated with a power back-off and a maximum transmission power determined according to a parameter associated with power management from the UE, wherein the PHR is triggered at the UE, when the periodic PHR timer is expired, and wherein the indicator is set to 1 if the determined maximum transmission power is different from a maximum power transmission not applying the power back-off due to the power management.
