METHOD AND DEVICE FOR REPORTING AND OBTAINING POWER HEADROOM

摘要

Disclosed are a method and device for reporting and obtaining power headroom. The method comprises: user equipment (UE) configuring a maximum transmit power (Pcmax); the UE using the Pcmax to calculate power headroom (PH); and the UE reporting the Pcmax and the PH to a base station. In embodiments of the present invention, the UE uses configured Pcmax to calculate power headroom (PH) and reports the Pcmax and the PH to the base station, so that the base station obtains the Pcmax and the PH at the same time, and thus the base station can use the PH accurately according to the Pcmax.
