Abstract  Abstract

PROBLEM TO BE SOLVED: To provide methods for user equipment performing power headroom reporting of each of active uplink component carriers employed in communications using carrier aggregation.

SOLUTION: In the communications user equipment includes one or more indicators and/or new MAC control elements in one or more protocol data units transmitted on respective component carriers within a single sub-frame that provides power status information to a base station device. The MAC control elements report a power headroom per user equipment piece. Alternatively the MAC control elements report power headrooms per component carrier and/or power reductions applied to the respective uplink component carriers.
