Abstract:
The invention is related to an apparatus comprising: a grouper configured to group antennas into antenna groups, if more antennas suitable for transmission are provided than pilot resources per a time slot; a rotator configured to rotate selected symbols with antenna-specific or antenna group-specific, and/or data symbol-specific phases; a transmitter configured to transmit symbols using a first antenna or antenna group of a user device and the rotated symbols using at least one second antenna or antenna group of the user device.
