Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a method for reporting power headroom.

SOLUTION: Power headroom may be reported across all carriers (wideband) for a specific carrier or for a carrier group. The formula used to calculate the power headroom depends on whether the carrier (or a carrier in the carrier group) has a valid uplink grant. If the carrier or carrier group does not have a valid uplink grant the power headroom may be calculated on the basis of a reference grant. The power headroom is calculated by a wireless transmit/receive unit and is reported to an eNodeB.
