Abstract  Abstract

claims a method for reporting power headroom. power headroom can be reported in all carriers (bandwidth) wherein said report can be for a particular carrier or one carrier group. for calculating a power headroom of formula depends on the carrier (or carrier group) has a valid uplink grant. If the carrier wave or carrier group does not have a valid uplink grant then can be a standard authorization to calculate power headroom. the power margin is by a wireless transmit/receive unit calculates and reports to the eNodeB.

A method for reporting power headroom is disclosed. 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 based on a reference grant. The power headroom is calculated by a wireless transmit/receive unit and is reported to an eNodeB.
