摘要:
The invention relates to a method for transmitting data in a radio communications system. According to said method, a radio interface is sub-divided into time slots for transmitting bursts, the data being transmitted in data channels in a time slot. Said data channels are distinguishable by an individual spread code. A terminal burst consisting of data symbols and at least one midamble with known symbols is used for transmitting data in a data channel. At least one parameter relating to the traffic conditions for the radio interface and the ratio of the length of midamble and of a data part with data symbols is adjusted according to the traffic conditions. The inventive method is particularly suitable for use in 3rd generation TD/CDMA mobile radio networks.

In order to compatibly adapt the air interface in a wireless telecommunications system with a CDMA, FDMA and TDMA multiple access component, especially a 'JD-CDMA' telecommunications system with hybrid multiple access techniques, to a GSM-specific/DECT-specific (micro, macro and/or pico-cell specific) telecommunications system, the signaling information configured as a 'stealing flag' to distinguish user channels from signaling channels is arranged in a given time slot structure in such a way that an asymmetric distribution of time slot data with respect to a training data block (midamble) of the time slot structure occurs. The transmission duration of a data element that is contained several times in the time slot structure and that is configured as a 'chip' is measured in such a way that said transmission duration is a harmonic multiple of a reciprocal predetermined pulse frequency, i.e. a GSM/DECT-specific pulse frequency, ranging from 5 to 7.

A process is disclosed for activating the antennas of a radio emitter/receiver, in particular of the base station (FT) or the mobile part (PT) of a cordless telephone having a central processor (DECT-C), a device (RSSI-C) for measuring the field intensity of received signals and if required a threshold value generator (TH-G). In order to determine which emitter antenna is to be activated, for example at the base station, independently from a special information of the mobile part, the central processor (DECT-C) carries out process steps designed in such a way that the field intensities (RSSI1, RSSI2, RSSI3) of signals received during said time intervals (T1.2, T2.2, T3.2) over the antennas (A1, A2) activated during said time intervals (T1.2, T2.2, T3.2) are measured during successive receiving time intervals (T1.2, T2.2, T3.2). Depending on the field intensities (RSSI1, RSSI2) measured in the successive time intervals (T1.2, T2.2) for the emitting time interval (T2.1) and for the receiving time interval (T2.2) following the time interval (T1.2) during which the measurement is carried out, one among several antennas (A1, A2) is activated for sending signals and for receiving signals.

A process and arrangement are disclosed for activating two antennas of a receiving device. The arrangement has a central processor (DECT-C), a device (RSSI-C) for measuring the field intensity of signals received over two antennas (A1, A2) and a threshold value generator (TH-G). The central processor (DECT-C) carries out process steps designed in such a way that during successive time intervals the field intensity of signals received during the corresponding time interval over the antennas (A1, A2) activated during the corresponding time interval is measured. Depending on the field intensities measured during said successive time intervals, the one or the other antenna (A1, A2) is activated for receiving the signals in the time interval that follows the time interval during which the measurement was carried out.

The installation proposed has a central processor (DECT-C), a device (RSSI-C) for measuring the field strength of received signals, a threshold-value generator (TH-C) and two antennae (A1, A2). The central processor (DECT-C) executes operations designed in such a way that various procedures (P1, P2) for the activation of one of several receiver antennae (A1, A2) are executed as a function of the measured field-strength values (RSSI1) of the received signals and in dependence of whether the value exceeds or falls short of a threshold value (THO).
摘要:
In a wireless telecommunications system, e.g. a DECT/GAP system, control mechanisms (i.e. messages, information elements and procedures) of a standard protocol are activated under the overall control of a first telecommunications device in the system in order to execute a special protocol; the control mechanisms serve for the exchange of additional information between the first telecommunications device and a second telecommunications device in the system.

The radio space to be covered by the stationary radio transmitter/receiver device, e.g. the base station of a wireless telephone, is covered by two or more directional aerials (3, 4) each covering a partial radio space thereof; the directional aerial activated being the one in the partial radio space of which the mobile radio transmitter/receiver device, e.g. the mobile part of the wireless telephone, is located (aerial diversity). This invention can be advantageously used in wireless telephones.

The invention relates to a method for identifying a first subscriber (T1) of a telecommunications network (TKN), a receiving terminal (EEE1) for identifying a first subscriber (T1) of a telecommunications network (TKN), and a transmitting terminal (SEE1). According to the inventive method, the identification of the first subscriber (T1) is carried out in such a manner that information of at least one type of information for identifying the first subscriber (T1) is output to at least one receiving terminal (EEE1), whereby the sole output of information of the information type text is excluded on the at least one receiving terminal (EEE1). This method enables identification capabilities to be integrated in a more diverse manner, in particular, multimedia representations are integrated during the identification of the first subscriber (T1) of the telecommunications network (TKN).
摘要:
The invention relates to a virtual assistant, which outputs audible information to a user of a data terminal by means of at least two electroacoustic converters, and to a method for presenting audible information of a virtual assistant for a user of a data terminal. In order to achieve an improved spatially acoustic separation between the information output by the virtual assistant over the electroacoustic converters and additional information output by at least one additional source of sound, the virtual assistant can be spatially positioned by the user of the data terminal. This enables the user to receive and process both information coming from the virtual assistant as well as information coming from the additional source of sound. The synchronous receiving and processing both of the information coming from the virtual assistant as well as that coming from the additional source of sound is at least facilitated for the user.
