Technique for generating a protocol data unit signal

Abstract:

A technique for generating a radio signal (504) for transmitting a protocol data unit (PDU) in a radio network is described. The PDU includes a first portion and a second portion. As to a method aspect of the technique, a first signal indicative of the first portion of the PDU is amplified for radio transmission using a power amplifier (630) in a first operating state. The power amplifier is switched from the first operating state to a second operating state different from the first operating state. A second signal indicative of the second portion of the PDU is amplified for radio transmission using the power amplifier in the second operating state, wherein a first bandwidth of the first signal is greater than a second bandwidth of the second signal.
