Abstract
A method and system are provided in which a mobile device may be operable for long term evolution (LTE) communication or some other wireless technology via two or more transmit antennas. The device may comprise a power amplifier for each transmit antenna with substantially similar maximum power being provided by both amplifiers. A power headroom value may be determined in the device based on path loss values between the transmit antennas and a base station and the maximum transmit power for each transmit antenna. Transmission via one of the transmit antennas may occur concurrently with transmission via another of the transmit antennas. The device may generate an indication of the determined power headroom value for communication to the base station. The power headroom value may be reported periodically or in response to a change in the power received at the base station.
