TECHNIQUE FOR RADIO TRANSMISSION UNDER VARYING CHANNEL CONDITIONS

Abstract:

A technique for radio transmitting data is described. As to a method aspect of the technique data to be transmitted to a receiver is represented by at least two partial modulation symbols. Each of the at least two partial modulation symbols is associated to a different layer of the radio transmission to the receiver. A modulation symbol is generated by combining the at least two partial modulation symbols at different power levels according to the associated layer. The modulation symbol is transmitted to the receiver.
