Abstract: In a radio communication system, a common channel is provided which is allocated to a plurality of subscribers at the same time for data transmission between a base station and a subscriber station. Measurements regarding the transmission quality are carried out on the common channel and their results are available in the base station. If the transmission quality does not meet a defined criterion, the base station transmits a first message to a controlling radio network controller associated therewith, the first message containing information about the transmission quality and about subscriber stations for which a bad transmission quality was measured. The controlling radio network controller sends a second message which informs serving radio network controllers, associated with the subscriber stations having bad transmission quality and responsible for the configuration of the subscriber stations, about the bad transmission quality.

Abstract: The invention relates to a management method for radio resources in a radio telecommunication system, in which a first radio telecommunication system has a first decentralized functional unit for managing radio resources, and a second radio telecommunication system has a second decentralized functional unit for managing radio resources. The first and the second decentralized function unit signal information with respect to a work load of the radio resources to a central functional unit for common radio resource management. The central functional unit evaluates this information and signals information with respect to load targets to at least one of the decentralized functional units, said information being taken into consideration by the decentralized functional unit in an intersystem handover.

Abstract: Disclosed is a valve having a housing with a valve seat for a two-piece flap which is rotatably mounted on a drive shaft. An annular piston seal and an adjacent cover disk are disposed between the first part and the second part of the two-piece flap so as to revolve therearound. The diameter of the cover disk is smaller than the diameter of the annular piston seal which is embodied as a metal ring that is provided with a gap. The invention also relates to the use of the valve as a gas recirculation valve.

Abstract: The invention relates to a management method for radio resources in a radio telecommunication system, in which a first radio telecommunication system has a first decentralized functional unit (serving RRM function) for managing radio resources, and a second radio telecommunication system has a second decentralized functional unit (neighbouring RRM function) for managing radio resources. The first and the second decentralized function unit signal information with respect to a work load (load measurements) of the radio resources to a central functional unit for common radio resource management (CRRM function). The central functional unit (CRRM function) evaluates this information (load measurements) and signals information with respect to load targets to at least one of the decentralized functional units, said information being taken into consideration by the decentralized functional unit in an intersystem handover (ISHO).

Abstract: A position determination method for a set of new points to be surveyed, using a geodetic device and reference points whose positions in an absolute coordinate system are known. The position determination is effected by referencing the new points relative to a set of reference points and measurement of the reference points and of the new points in a relative coordinate system for referencing by the geodetic device—relative measured quantities being registered. Furthermore, the new points and the reference points are updated by successive addition in each case of the measured new points and reference points to the set of new points and set of reference points, respectively, and updating the position determination of the new points taking into account all of the respective actual reference points is effected if a specified minimum coefficient of determination for the referencing is ensured by the actual set of reference points.

Abstract: In the novel method for data transmission via a radio interface in a radio communications system, at least two data channels are assigned to one connection. Each data channel can be distinguished by an individual spread code. In addition to data symbols, midambles with known symbols are transmitted in a data channel. The number of midambles being used for the connection is less than the number of data channels. The method is particularly suitable for use in TD/CDMA 3rd generation mobile radio networks.

Abstract: In order to compatibly adapt a wireless telecommunication system with a CDMA, FDMA and TDMA multiple access component, particularly a hybrid “JD-CDMA” telecommunication system with respect to multiple access methods, to a GSM-specific/DECT-specific (micro-cell, macro-cell and/or Pico cell-specific) telecommunication system with respect to the air interface, signaling information fashioned as “stealing flag” for distinguishing between payload and signaling channels are first arranged such in a provided time slot structure that an asymmetrical division of the time slot data arises with respect to a training data block (midamble) of the time slot structure and, second, the transmission time duration for the provided time slot structure of a data element fashioned as “chip” and contained in the time slot structure is dimensioned such that this is a multiple of a predetermined clock frequency—for example, GSM/DECT-specific clock frequency—covering the numerical range

Abstract: In a method and arrangement for channel allocation in a radio communication system that uses a TD/CDMA subscriber separation method, an allocation of at least one channel is signalled to a radio station by an information element in a signalling message. At least one time slot is thereby selected by a time slot selection sub-information element. Subsequently, at least one CDMA code is selected for each selected time slot with a code selection sub-information element, whereby a number of code selection sub-information elements corresponds to a number of selected time slots.

Abstract: In a method for data transmission in a radio communications system, a radio interface is subdivided into time slots for a transmission of bursts. In this case, the data are transmitted in data channels in a time slot, in which data channels can be distinguished by use of individual spread codes. A finite burst containing data symbols and at least one midamble with known symbols is used for data transmission in a data channel. At least one parameter is determined for the traffic conditions of the radio interface, and a ratio of a length of the midamble and a data part with data symbols is adjusted depending on the traffic conditions. The method is suitable in particular for use in 3rd generation TD/CDMA mobile radio networks.

Abstract: When a laser beam is focussed onto a substrate for the purpose of substrate processing, the optical units such as beam expander, deflecting unit, and optical imaging device prescribe the range of depth of focus in which it is possible to work with a minimum spot size. The difficulty of boring thin holes, especially in thick substrates, is overcome with a second laser beam that is widened via a second beam expander and likewise focused onto the substrate via the deflecting unit and the optical imaging device. The position and the length of the second range of depth of focus can be varied by selecting the magnification of the second beam expander or by maladjustment. Thin holes can also be bored into thick substrates by using the two laser beams one after another.

Abstract: Data is transmitted via a radio interface in a radio communications system in that at least one subscriber signal is transmitted, which has an individual fine structure applied to it and, in addition to data symbols in data sections, contains a midamble with known symbols. The fine structures of the data sections and of the midamble differ. At the transmission end, a sum signal is produced which contains signal sections to which different fine structures are applied. The sum signal is filtered in at least one transmission filter and is transmitted via a transmission channel to a receiving radio station. A control device controls the addition so that different attenuation of the signal sections is compensated for by the filtering. The method is suitable, in particular, for mobile stations having a single or variable data rate, and for base stations for use in 3rd generation TD/CDMA mobile radio networks.
