Technique For Generating a Protocol Data Unit Signal

A method of generating a radio signal for transmitting a protocol data unit (PDU) in a radio network, wherein the PDU includes a first portion and a second portion, the method comprising:

• amplifying a first signal indicative of the first portion of the PDU for radio transmission using a power amplifier in a first operating state;
• switching the power amplifier from the first operating state to a second operating state different from the first operating state;
• and
• amplifying a second signal indicative of the second portion of the PDU 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.

A device for generating a radio signal for transmitting a protocol data unit (PDU) in a radio network, wherein the PDU includes a first portion and a second portion, the device comprising:

• processing circuitry;
• memory containing instructions executable by the processing circuitry whereby the device is operative to:
• amplify a first signal indicative of the first portion of the PDU for radio transmission using a power amplifier in a first operating state;
• switch the power amplifier from the first operating state to a second operating state different from the first operating state;
• and
• amplify a second signal indicative of the second portion of the PDU 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.
