Patent number: 10230482Abstract: A radio transceiver circuit for FDD communication is disclosed. It comprises a transmitter for FDD signal transmission in a first frequency band, a first receiver for FDD signal reception in a second frequency band, separate from the first frequency band, and a duplexer. An output port of the transmitter is operatively connected to a first port of the duplexer for transmitting, through the duplexer, signals in said first frequency band. An input port of the first receiver is operatively connected to a second port of the duplexer for receiving, through the duplexer, signals in said second frequency band. The radio transceiver circuit comprises a second receiver, separate from the first receiver, for reception in said first frequency band. An input port of the second receiver is operatively connected to said first port of the duplexer for receiving, through the duplexer, signals in said first frequency band. A related radio communication apparatus is also disclosed.Type: GrantFiled: July 4, 2017Date of Patent: March 12, 2019Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (publ)Inventors: Lars Sundstrom, Sven Mattison, Anders Wallen

Publication number: 20160126912Abstract: An attenuator control method of a signal processing chain comprising two or more signal processing units is disclosed. One of the two or more signal processing units is a signal attenuator adapted to apply adaptive signal attenuation of an attenuator input signal based on one or more attenuation parameters to provide an attenuator output signal. At least one of the two or more signal processing units has an associated wearout process and a corresponding wearout budget, wherein a wearout event of the wearout process occurs when a level of a wearout indication signal of the signal processing chain is in a wearout region, and wherein the wearout process is modeled by a wearout event cost associated with a corresponding wearout event. The method comprises obtaining an indication of whether a wearout event of the wearout process has occurred.Type: ApplicationFiled: June 13, 2013Publication date: May 5, 2016Inventors: Lars Sundström, Daniele Mastantuono, Sven Mattison, Roland Strandberg
