Patent number: 11637573Abstract: An apparatus comprises a digital processing device configured to generate a digital transmission signal, a digital-to-analog converter connected to the digital processing device and configured to convert the digital transmission signal into an analog transmission signal, and a power amplifier connected to the digital-to-analog converter and configured to amplify the analog transmission signal. An antenna filter is connected to the power amplifier and configured to filter the amplified analog transmission signal; the antenna filter is configured to pass frequencies in at least one passband and to attenuate frequencies in at least one stopband. The digital processing device is configured to perform a process of reducing peak power in the digital transmission signal; in this process error components having different frequencies are produced. A frequency spectrum of the error components is manipulated such that a part of the error components is deposited in the stopband of the antenna filter.Type: GrantFiled: October 10, 2022Date of Patent: April 25, 2023Assignee: NOKIA SOLUTIONS AND NETWORKS OYInventors: Gunter Wolff, Radoslaw Ceszkiel, Grzegorz Haza, Björn Jelonnek, Michael Weber

Patent number: 11632747Abstract: Various communication systems may benefit from an improved signaling protocol. For example, communication systems may benefit from an improved network support for a narrowband internet of things in a hosting long term evolution carrier. A method, in certain embodiments, includes shifting a frequency of a downlink long term evolution channel by a pre-determined amount. The shift causes a duplex distance between the downlink long term evolution channel and an uplink long term evolution channel to change. The method includes blanking at least one overlapping radio resource in at least one of the uplink long term evolution channel or an uplink narrowband internet of things channel. The uplink narrowband internet of things channel and the uplink long term evolution channel at least partially overlap. In addition, the method includes receiving data on the uplink narrowband internet of things channel and an additional uplink narrowband internet of things channel at a network entity from a user equipment.Type: GrantFiled: March 15, 2021Date of Patent: April 18, 2023Assignees: Nokia of America Corporation, Nokia Solutions and Networks GMBH & Co.

Patent number: 8837634Abstract: Systems and techniques for signal filtering are described. A bandpass filter is defined so as to provide for a reduced rolloff region so as to avoid interference with an adjacent carrier. Definition of the bandpass filter provides for a frequency response that compensates for loss of signal components in the rolloff region. Definition of the bandpass filter may be based at least in part on characteristics of a specified legacy filter used by devices from which signals may be received or to which signals may be transmitted.Type: GrantFiled: October 5, 2012Date of Patent: September 16, 2014Assignee: Nokia Siemens Networks OyInventors: Gunter Wolff, Radoslaw Ceszkiel
