Abstract
Method and system for power headroom reporting in a mobile device capable of supporting multiple radio transmissions via different channels. The available maximum power variation of a second channel is estimated based on power usage in radio transmission of a first channel. A plurality of measures related to radio transmission via the second channel are them computed. Whether one or more conditions for power headroom reporting of the second channel are met is tested in accordance with a configuration with respect to power headroom reporting. The power headroom is computed based on the estimated power variation relating to the first channel and the radio transmission measures relating to the second channel. A power headroom report is then generated based on the computed power headroom and such a report is then transmitted, typically from the mobile device to a base station.
