Claim Text:
1. A method for reducing energy consumption in a wireless communication terminal able to simultaneously transmit signals in at least a first frequency band and a second frequency band, said method comprising: extracting control data for signals to be transmitted, for transmission of a first burst of signals in a first frequency band and of a second burst of signals in a second frequency band, comparing transmission instants of the first and second bursts in order to detect whether or not there is a temporal conflict between the transmission instants, and, in the case where there is no temporal conflict and according to the extracted control data, routing the signals of one of the first or second frequency bands from a respective first or second circuit via a summer to a power amplifier of a front-end module of the other circuit of the other frequency band and disconnecting the power amplifier of the front-end module of the circuit of the frequency band of said signals; in the case where there is temporal conflict, verifying the linearity of the power amplifier to determine whether or not to route the signals of the one of the first or second frequency bands from the respective first or second circuit via the summer to the power amplifier of the front-end module of the other circuit of the other frequency band.
