The invention relates to a device for a radio communications system, the device including: a processing unit; a memory unit; and a transceiver including a transmitter provided with a power amplifier; wherein said device is configurable to: send a request to a base station of said communications system for permission of transmission of one or more data symbols, the one or more data symbols being amplified with the power amplifier in an overdrive regime; receive a grant for such transmission; amplify the one or more data symbols with the power amplifier of the transmitter in the overdrive regime; and transmit the one or more data symbols to the base station.

Method and apparatus for performing permissable amplifying of one or more data symbols using an overdrive regime

Embodiments relate to a multiband transceiver apparatus (), comprising a first transmit path () operable to transmit a first transmit signal (sig) in a first radio frequency band (RF), wherein the first transmit path () comprises an input (), an output () and a first feedback path () from the output towards the input of the first transmit path, a second transmit path () operable to transmit a second signal (sig) in a second radio frequency band (RF), the second radio frequency band (RF) being different from the first radio frequency band (RF), wherein the second transmit path () comprises an input (), an output () and a second feedback path () from the output towards the input of the second transmit path, and a cross-talk canceller () operable to cancel cross-talk from the second feedback path () to the first feedback path () and/or to cancel cross-talk from the first feedback path () to the second feedback path () of the multiband transceiver apparatus ().

Cross-talk cancellation in a multiband transceiver

The invention relates to a method for amplifying a carrier signal (CS) by using a power amplifier (PA), the power amplifier (PA) is feed with a supply voltage (PASV) of a power supply (SMPS). The method comprises the step of adapting a value of the supply voltage (PASV) to a value related to a mean signal power of an input signal (DS) of a power amplifier system (PAS).

Method for amplifying a signal by a power amplifier, power amplifier system, device, computer program product, and digital storage medium thereof
