摘要： 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. power for a predetermined first period of time and then with the reduced transmitting power, which matches the mobile station received as the "weakest one", for a predetermined second period of time.

摘要： A radio communications system provides frequency channels which are formed both by time slots and by broadband frequency ranges, and in which information from a plurality of connections is simultaneously transmitted between mobile stations and base stations wherein it is possible to distinguish the information from different connections in accordance with a connection-specific fine structure. Frequency channels are repeatedly provided for time synchronization of the mobile stations in the downward direction in which a signal form is transmitted in addition to information from further connections. The mobile station to be synchronized determines from received signals at least one instant of the arrival of the signal form, which is subsequently used by the mobile station for time synchronization. The system is advantageously applied, for example, in TDD mode for the third mobile communications generation which combines a TDMA and CDMA subscriber separation method.

摘要： The correlations of different channel impulse responses are used to improve, simplify and optimize the assessment of wire-free transmission channels in telecommunications systems. In particular, the different channel and pulse responses are correlated by identifying a similarity between the different responses and driving a mean channel impulse response from the different channel impulse responses when they are identified as similar.

摘要： According to the inventive method for channel estimation, a number of midamble codes is derived from at least two midamble base codes by means of an individual time shift of the respective mitamble base code. A mitamble code is allocated to a first radio station which sends said mitamble code in the form of a burst. A second radio station receives the sent burst, whereby the mitamble code is considered for canal estimation in the second radio station.

摘要： 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 radi o 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 variabl e step size in transmission power regulation. The variable step size is subscriber-dependent and time-dependent regulated by the radio stations.

摘要： According to the invention one or more channels which form a control channel are assigned to a base station for the transmission of control information. This makes it possible to vary the bit rate of the control channel. At least one synchronization sequence is transmitted by the base station and the channel(s) of the control channel correspond to the selection of one or more synchronization sequences and/or a succession of several synchronization sequences. A subscriber station receives the at least one synchronization sequence and determines the configuration of the control channel on the basis of the synchronization sequence recognized and/or the succession of synchronization sequences recognized, which indicate the channel(s). Many variants of a single synchronization sequence and/or the order in which different synchronization sequences are transmitted can, for example, be used to indicate the configuration of the control channel. In this way the presence of a scalable control channel can be indicated already in the synchronization phase and with little additional effort.

摘要： The method involves determining a utilization of a monitoring radio channel, whose operating condition is determined continuously and repeatedly. The utilization is determined through evaluation of a history of the operating condition. An average value of the operating condition over a monitoring period is preferably determined for the evaluation of the history. A value of a size characteristic for the operating condition is preferably determined, whereby it is determined whether the characteristic size under- or oversteps a predetermined threshold over the monitoring period, and whereby short-term variations remain unconsidered for the evaluation of the history of the operating condition.
