Claim Text:
1. A method for use in interference reduction for an envelope branch type transmitter in a transceiver that further includes a receiver, the method comprising: determining a target frequency span for reducing interference caused by the envelope branch type transmitter, the determination of the target frequency span being made between at least (i) a first frequency band that corresponds to an adjacent channel to a transmit frequency band for a radio transmission of the envelope branch type transmitter and (ii) a second frequency band that corresponds to a receive band of the receiver, the determination of which of the first frequency band and the second frequency span is the target frequency band being based on at least one of a predetermined setting and a current interference condition; and configuring a differential delay between a signal branch and an envelope branch of the envelope branch type transmitter on the basis of the determined target frequency span, wherein the differential delay is determined based on at least one of selecting the differential delay or the delay adjustment value from a predetermined set of differential delays or delay adjustment values depending on the determined target frequency span and deriving the differential delay based on at least feedback and/or control information from an external device.
