摘要： 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.

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 method for allocating radio channels in a radio communications system having timeslots includes the steps of allocating the radio channel for the downlink direction to a mobile station as a function of a channel allocation pattern which indicates the transmission power levels for the timeslots. The mobile station corrects the allocation of the radio channel as a function of an interference pattern which indicates the interference power levels in the timeslots. The allocation process results in the transmission power level being distributed as uniformly as possible between the timeslots which are provided for a connection from the radio station in the downlink direction, wherein the allocation process is a function of the occupancy of the timeslots in accordance with the channel allocation pattern. The ability of correcting the allocated timeslot under the control of the mobile station allows to avoid a disadvantageous soft handover, even with a frequency repetition interval equal to unity which is critical with respect to interference.

摘要： In a wireless communication system having at least first and second radio stations located at a network end and connected to a core network, the first radio station receives a registration message from a user station to initially register the user station in a radio station located at the network end, after the user station has been switched on. Subsequently, communication takes place between the core network and the user station. Signaling messages that are to be sent from the core network to the user station are transmitted, at least at the beginning of the communication between the core network and the user station, from the core network to the second radio station, then from the second radio station to the first radio station or another radio station located at the network end, and from the first radio station (or the other radio station) directly to the user station.

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： A method is described in which a signaling message is sent from a first radio station to a second radio station. The message contains information relating to both a frequency channel number and a frequency channel bandwidth, each referring to a common standard bandwidth. The signaling message is received by the second radio station, and the signaled frequency channel is used for transmission and reception purposes. The data relating to the frequency channel number and the bandwidth indicate which frequency channel has to be used. In addition the signal includes information about using radio communication systems with a plurality of non-interconnected frequency bands and with bandwidths intended for various applications.

摘要： A mechanism for controlling resources and/or settings of an access network element like a base station is provided which allows an autonomous reconfiguration of, for example, the antenna configuration based on a set of performance indicators in a base station. The base station can reconfigure itself without the need of operator control so that during periods with low capacity demands the base station will reconfigure correspondingly, which may include a reduction of active cells by turning off the power for a part of the installed equipment.

摘要： The invention relates to a method for increasing the precision during the determination of system parameters dependent on the propagation delay, e.g. for a positional determination, in a mobile communications system with emission diversity, according to which a subscriber data signal and a reference signal are assigned to a subscriber. The subscriber data signal is emitted by at least two antenna devices on the emission side, whereas the reference signal is emitted exclusively by one antenna device on the emission side. The reference signal is used to precisely determine signal propagation delays, upon which the system parameters depend.
