Publication number: 20250338165Abstract: Embodiments of the present disclosure relate to methods, devices, apparatuses, and computer readable medium for macro-diversity transmission in a subnetwork. The method comprises: in response to receiving a first header identification associated with a Time Sensitive Communication (TSC) stream, a first device transmits, to a configuration entity of a transport network, a first stream requirement comprising two or more second identifications. Each of the two or more second identifications is associated with a corresponding second device configured for an interface end station in a first protocol plane. The first device receives communication configuration information indicating second header information from the configuration entity. Then, the first device transmits, to a second device operating as a source interface end station, the first header identification and third header information at least indicating the second header information.Type: ApplicationFiled: June 7, 2022Publication date: October 30, 2025Inventors: Christian MARKWART, Rüdiger HALFMANN, Hua CHAO, Rakash SIVASIVA GANESAN

Patent number: 8260307Abstract: Radio stations in a radio communication system send messages from one radio station to another either directly or via one or several radio stations forwarding the messages by using radio resources. The radio resources are allocated in a decentralized manner to radio stations to send the message. At least one radio station sends information about first radio resources used for sending at least one message to the at least one radio station, the information about the first radio resources being sent by using second radio resources that are allocated to the at least one radio station.Type: GrantFiled: September 13, 2004Date of Patent: September 4, 2012Assignee: Siemens AktiengesellschaftInventors: Rüdiger Halfmann, Matthias Lott, Michael Meincke, Egon Schulz

Patent number: 8175062Abstract: In a communication system, a first transmitting station transmits a transmission signal to a first receiving station for transmitting a sequence of data via a radio interface. The radio interface is monitored with respect to an interference signal from an interference source prior to transmission via at least one of the first transmitting station and the first receiving station. The transmission only begins if the radio interface is sufficiently free from interference for a moment in time.Type: GrantFiled: September 30, 2008Date of Patent: May 8, 2012Assignee: Nokia Siemens Networks GmbH & Co.

Patent number: 8165239Abstract: Data symbols, transmitted by OFDM radio using at least two transmission antennae, are coded by a DSTBC coding and a DSTFBC coding. Two adjacent data symbols of a selected sub-carrier are provided for initializing a DSTFBC coding in a sub-carrier direction and are used for DSTFBC coding of similarly positioned data symbols in further sub-carriers in the sub-carrier. The DSTFBC coding is carried out from the data symbols of the first sub-carrier direction. In each sub-carrier the two data symbols formed by DSTFBC coding are used for initializing a DSTBC coding in the OFDM symbol direction. In the reverse direction, two sequential DSTBC coded data symbols on a first sub-carrier for initializing a DSTFBC coding in a sub-carrier direction and are used for DSTFBC coding of similarly positioned data symbols in further sub-carriers for DSTFBC coding from the data symbols of the first sub-carrier over the adjacent sub-carriers.Type: GrantFiled: December 15, 2006Date of Patent: April 24, 2012Assignee: Nokia Siemens Networks GmbH & Co.

Patent number: 8009755Abstract: In an OFDM multi carrier modulation method, M sub-carriers are used in a frequency band of a broadband mobile radio channel and several symbols are used in a time band. With application of a MIMO multi-antenna method with T transmitting antennae and R receiving antennae, for all sub-carriers and all symbols, a single, pre-determined, channel-matched transmission strategy is used, which is described by a maximum of T*R complex values on the signal side, independent of the species of the MIMO multi-antenna method and independent of the size of the frequency/time bands.Type: GrantFiled: December 12, 2006Date of Patent: August 30, 2011Inventors: Rüdiger Halfmann, Eduard Jorswieck, Egon Schulz, Martin Weckerle

Patent number: 7656962Abstract: The invention relates to a method for transmitting signals in a radio communication system consisting of at least two frequency signal-transmitting channels. At least the first (fcoord) of said frequency channels is used for organizing radio resources, and at least the second (fi) of the frequency channels is used for transmitting signals between the stations of the system where the signal transmission is carried out by the frequency channels from/in a direction of said stations in conformity with a predefined temporal pattern (P1, P2, P3).Type: GrantFiled: February 20, 2004Date of Patent: February 2, 2010Assignee: Siemens AktiengesellschaftInventors: Rüdiger Halfmann, Matthias Lott, Egon Schulz
