Abstract: To transmit data packets between a transmitter and a receiver, the data packets are transmitted in coded from as coding units. The received data packets are stored in coded or uncoded form in the receiver inside a memory. The receiver notifies the transmitter of the capacity utilization of the memory.

Abstract: 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.

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: In a cellular telecommunications system using wireless telecommunication between mobile parts and base stations, a method of handing off telecommunications connections from uncoordinated, unlicensed operation of the system to coordinated, licensed operation and vice versa. The method requires only simple circuitry and little energy consumption in the mobile parts. Initial monitoring is carried out in the base station, which supports uncoordinated, unlicensed system operation.

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: In order to control the transmitting power provided for point-to-multipoint telecommunications links in a telecommunications system with wireless telecommunication and uncoordinated unlicensed system operation, without significant restriction of the transmitting range, use is made of the fact that the maximum number of mobile stations (MS1 . . . MSn) registered in a base station (BS1) is known. Thus, the base station knows at any time how many and which mobile stations are registered. If all mobile stations are registered (NACT=NSCHED), the base station can match the transmitting power to the mobile station received as the “weakest one”. In other cases, if not all mobile stations are registered (NACT≠NSCHED), the base station will alternately transmit with the maximum transmitting.

The received data packets are stored in coded or uncoded form in the receiver inside a memory. The receiver notifies the transmitter of the capacity utilization of the memory.

Abstract: A method of operating a high speed, error-free data transmission system in a noisy medium includes compressing data determined to be compressible, forward error correcting the data and interleaving the data in a bit matrix memory to enhance the forward error correction. Digital information packets are formulated including a header bearing a packet number, the total packet byte count, any packet number resend request, the data byte count of the actual data and a CRC. The digital information packet is loaded onto a transmitter carousel having a fixed number of sectors. The receiver receives the data, requests resend of any packet (by number) that is defective, error corrects if necessary and sequentially loads the packet onto a receiver carousel. Packets or sequential packet groups are removed from the carousel, selectively decompressed and the data words extracted and sent to the output.

Abstract: An individual parameter with respect to a required receptivity is determined for at least one service, and is sent by a base station, in a radio communications system which offers a number of services for mobile stations via a radio interface in a radio cell. A mobile station receives and evaluates the parameter, then compares the current receptivity of emissions of the base station with the parameter. The service is requested by the mobile station in dependence on the result of the comparison. The invention is suitable for use in TDMA and CDMA transmission systems.

Abstract: A method for transmitting organization information items from a base station to mobile stations in a radio communications system which offers a plurality of services within a radio cell of the base station. The organization information items are subdivided into first and second organization information items on the basis of the services requested at a given moment and only the first organization information items are transmitted. As a result, the currently required information items are made available in a manner that saves resources, yet the integration of new services is made possible. The method is suitable for TDMA/CDMA and CDMA transmission systems.
