Abstract
A mobile communication device may transmit a signal using a plurality of antenna elements, the signals differing by a transmit diversity parameter, e.g., a phase difference. The mobile communication device may receive a quality-indication signal from a basestation, e.g., a power control bit or signal. A sequence of the power control bits or signals may be used to provide feedback to the mobile communication device to determine a change in a transmit diversity parameter.
