Publication number: 20230118653Abstract: A user equipment, method and computer program for adjusting an effective centre frequency of channel filter in a user equipment to improve the adjacent selectivity when the network is transmitting on an irregular bandwidth channel and the user equipment is receiving the signal via a channel filter that has a wider pass band than the bandwidth of the channel. The method comprises filtering received wireless communication signals at a channel filter. Identifying a preferred centre frequency for the channel filter by: adjusting a centre frequency of the channel filter; determining a level of adjacent channel selectivity of signals filtered by the channel filter; comparing a level of adjacent channel selectivity at different centre frequencies of the channel filter; and identifying the preferred centre frequency as the centre frequency that provides a highest level of adjacent channel selectivity.Type: ApplicationFiled: September 30, 2022Publication date: April 20, 2023Applicant: Nokia Technologies OyInventors: Kim NIELSEN, Faranaz SABOURI-SICHANI, Iwajlo ANGELOW

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. KG, Nokia UK LimitedInventors: Gunter Wolff, Man Hung Ng, Iwajlo Angelow

Publication number: 20100029291Abstract: A method controls a time-based transmission of signals of a subscriber terminal for synchronous reception at a base station of a radio communication system. Upon detection that a determined time offset of received signals is equal to or greater than a predetermined threshold value, a change from one-step control commands to multi-step control commands for controlling the time-based transmission of the subscriber terminal is performed by the base station, or a synchronization procedure is initiated by means of a randomly chosen access channel by the subscriber terminal.Type: ApplicationFiled: October 1, 2007Publication date: February 4, 2010Inventors: Iwajlo Angelow, Mieszko Chmiel

Publication number: 20090046670Abstract: A method for data transmission in a radio communication system, in which data of a plurality of subscribers is combined with the aid of a multiplexing method to form frames, and is transmitted by means of sub-carriers. At least two frame structures are provided for transmission of the frames, with the frame structures differing in the respectively associated number of pilot signals and/or in the distribution or grouping of associated pilot signals. Each subscriber determines an individual progress speed, and each subscriber is allocated to one of at least two speed ranges, depending on the progress speed. A frame structure which is individually associated with the speed range, on the one hand, and an individually associated number of sub-carriers, on the other hand, are used in order to transmit the data from subscribers who are allocated to an identical speed range on the basis of their progress speed.Type: ApplicationFiled: October 11, 2006Publication date: February 19, 2009Inventors: Iwajlo Angelow, Volker Breuer, Mieszko Chmiel
