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