Patent number: 8989168Abstract: Data rates of simultaneous radio transmissions of data are matched for services over a connection between a base station and a subscriber station by determining a service-specific rate matching factor for one of the services based on a steady-state rate matching factor and a dynamic rate matching factor. The dynamic connection-oriented rate matching factor is based on the steady-state matching factor. The dynamic-connection oriented rate matching factor matches a sum of a volume of data for the services over the connection to a volume of data available in a next frame of data. In addition, the data is compressed or expanded for the one of the services based on the corresponding service-specific rate matching factor.Type: GrantFiled: June 16, 2008Date of Patent: March 24, 2015Assignee: Siemens AktiengesellschaftInventors: Anja Klein, Reinhard Koehn, Joern Krause, Volker Sommer, Thomas Ulrich

Method, mobile station and base station for establishing connections in a radiocommunications system
Patent number: 8229489Abstract: A radio communication system, for example a TDMA/CDMA radio communication system, has at least one base station recurringly offering frequency channels for a random access for mobile stations in an upstream direction. The mobile station that requests a connection setup measures a reception power of a signal sent in a downstream direction by the base station and sets a transmission power for sending an access radio block to the base station dependent on the measured reception power. A variable transmission power control can thus be implemented at the mobile station side with the assistance of the measured reception power of the signal transmitted on the part of the base station, being also capable of being implemented for random access of the mobile stations, this having previously always occurred with maximum transmission power.Type: GrantFiled: October 26, 1998Date of Patent: July 24, 2012Assignee: Siemens AktiengesellschaftInventors: Anja Klein, Michael Färber, Christian Lüders -
Patent number: 8180914Abstract: A system and method to delete overload in a data stream are described. A method of an embodiment of the invention may analyze data quality information in a data stream and delete data items that are found to be of lower than a desired data quality. In one embodiment, data items may be evaluated according to maximize a particular aspect of the utility of the data in a data stream. In one embodiment, a system of an embodiment of the invention may evaluate data quality in a data stream to suggest one or more actions to be performed to improve the data quality in the data stream.

Patent number: 7106705Abstract: For a communication system (e.g. UMTS with CDMA radio interface), the invention draws a distinction between services with high and low data rate dynamics and uses a matched type of signaling for the transport formats currently being used. The data rate of the data for a service can fluctuate greatly and/or rapidly over time (high dynamics), or may fluctuate only a little and/or slowly (low dynamics). The data for the services are transmitted via a common physical channel, with in-band signaling being used for signaling the transport format for the services with high data rate dynamics, and with signaling in a separate channel being used for the services with low data rate dynamics.Type: GrantFiled: November 25, 1999Date of Patent: September 12, 2006Assignee: Siemens AGInventors: Christoph Mecklenbräuker, Michael Benz, Anja Klein, Reinhard Köhn, Jörn Krause, Christian Menzel, Enric Mitjana, Erik Newton, Martin Öttl, Dave Randall, Armin Sitte, Jean-Michel Traynard, Thomas Ulrich

Patent number: 7088697Abstract: According to the invention, signalling of the used common channels is carried out implicitly via the data rate. Several combinations of channels (spread codes) are only permitted as an alternative for particular data rates of the individual services. Transmission capacity is saved since it is not necessary to reserve individual bits inside the TFCI parameter uniquely for the allocation of said common channels to different connections. The invention is especially useful in the downlink of the FDD modus of UMTS mobile radio systems.Type: GrantFiled: December 1, 1999Date of Patent: August 8, 2006Assignee: Siemens AktiengesellschaftInventors: Michael Benz, Anja Klein, Reinhard Koehn, Volker Sommer

Patent number: 7068629Abstract: A method and radio communication system for synchronizing subscriber stations, wherein a time slot is assigned to a number of base stations for transmitting at least one synchronization sequence and adjacent base stations use a different time offset with respect to the beginning of the time slot for transmitting the synchronization sequence. Thus, superposition can be precluded even in the case of a synchronized operation of the base stations. So that the subscriber station can still determine the beginning of the time slot, the time offset is transmitted. The time offset corresponds to the choice of one or more synchronization sequences and/or the sequence of a number of synchronization sequences. The information relating to the time offset is transmitted coded in this manner.Type: GrantFiled: September 3, 1999Date of Patent: June 27, 2006Assignee: Siemens AktiengesellschaftInventors: Michael Benz, Anja Klein, Armin Sitte, Thomas Ulrich, Michael Faerber, Meik Kottkamp, Volker Sommer
