Abstract:
A power headroom calculation method and apparatus of a User Equipment (UE) are provided for a primary cell Power Headroom (PH) calculation in a Long Term Evolution-Advanced (LTE-A) mobile communication system. The method includes determining whether an activated serving cell includes uplink data and/or uplink control signal to be transmitted, and determining PH of the activated serving cell according to whether the activated serving cell has the uplink data and/or uplink control signal.
