Abstract

A carrier aggregation power headroom reporting method is disclosed. User equipment selects from one of four possible definitions of a single parameter used to calculate the power headroom of the user equipment. The user equipment uses the parameter to calculate the power headroom for two different equations. The two results are transmitted to the enhanced base station.
