Abstract: 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.

Abstract: A method regulates the transmission power of a transmitter in a radio system, for a transmission of data to a receiver by a radio interface. The receiver determines an actual value for a qualitative parameter of the received signal, makes a comparison with a set value and, thereafter, transmits comparison information on the result of the comparison to the transmitter. Adjustment of the transmission power of the transmitter is made based on a correction value for the set value of the qualitative parameter of the received signal, in addition to comparison information from the receiver.

Abstract: Messages relating to a multimedia broadcast/multicast service are transmitted in a radio communication system, where subscriber stations are informed by a service-dedicated paging display channel prior to the transmission of useful information as a service which is provided for several subscribers.

Abstract: A method and apparatus for data rate matching, wherein elements to be transmitted are distributed over a number of radio frames via an interleaver and are punctured or repeated, with the puncturing or repetition being carried out in such a manner that, when it is related to the original arrangement of the element before interleaving, the pattern avoids puncturing or repetition of adjacent elements, or of elements which are not far apart from one another.

Abstract: 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.

Abstract: 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.

Abstract: According to the invention, transmissions of the second radio station are received in the first radio station in which the operating instruction for transmission power of the second radio station is determined. The operating instruction is transmitted during a following transmission of the first radio station to the second radio station, whereupon the latter takes into account the operating instruction for power regulation during one of its following transmissions. Contrary to prior art, no time invariable or fixed step size is used. An operating instruction is used instead which is related to a variable step size in transmission power regulation. The variable step size is subscriber-dependent and time-dependent regulated by the radio stations.

Abstract: A data communications apparatus, which communicates data frames, includes a converter, which converts a data frame into a data block for transmission. The data block has a size which is different than a size of the data frame. The converter includes a puncturer for puncturing or repeating bits or symbols at positions within the data frame that are determined in accordance with a selection strategy. The selection strategy uses a digital differential analyzer-type algorithm.

Abstract: According to the invention, a service-specific static rate adaptation factor that controls a service-specific quality of service is determined in a manner already known per se. A dynamic rate-oriented rate adaptation factor is determined for a link, whereby said factor adapts the hypothetical volume of data to a volume of data that is available in the next frame while taking into account the adaptation of the service-specific data rate that is yet to be performed. It is possible to pass through several optimization loops if said data volume is not rigidly predetermined as a result of a sufficient number of transmission channels and spread factors. A service-specific rate adaptation factor is determined by combining the static rate adaptation factor and the dynamic link-related rate adaptation factor, whereupon one single and therefore one-step adaptation of the data rate is carried out.

Abstract: A frame is provided for vehicle sliding sunroofs, the frame front member of which is injection molded in one piece from a suitable plastic and has molded-on side arms for the connection of frame side members. Molded-on swivel bearings for supporting the deployment arms of a wind deflector, arranged on the frame front member, are incorporated into the frame front member and the side arms. The wind deflector can be specially fitted to the swivel bearings without the aid of separate fasteners, in that the swivel bearings and the associated swivel bearing pivot pins of the wind deflector are designed in the manner of so-called turn catches.

Abstract: The invention relates to a method for regulating the transmission power of a transmitter (BS) in a radio system, for a transmission of data (D) to a receiver (MS) by means of a radio interface. The receiver (MS) determines an actual value (PR) for a qualitative parameter of the received signal, makes a comparison with a set value (Psoll) and, thereafter, transmits comparison information (TPC) on the result of the comparison to the transmitter. Adjustment of the transmission power (PT) of the transmitter (BS) is made based on a correction value for the set value (Psoll) of the qualitative parameter of the received signal, in addition to comparison information (TPC) from the receiver (MS).

Abstract: The invention relates to a method for transmitting data bits (B) in a communications system. Said bits are allocated to a communications connection and are present in a sequential manner. Transmission channels (Chi) which have been separated according to a CDMA method are provided in the communications system. An individual spread code (SCi) is allocated to said channels respectively. The inventive method comprises the following steps: C≧2 of the transmission channels (Chi) are allocated to the communications connection. Consecutive bits (B) are combined to form bit groups (BG), whereby each group is provided with at least one bit and M bits at the most. Several bit groups (BG) are allocated to each transmission channel (CHi) in such a way that bit groups that were adjacent before allocation are allocated to different transmission channels after the allocation. M≧1 consecutive bits (B) of the bit groups (BG) allocated thereto are combined to form symbols (SY) for each transmission channel (CHi).
