FIG. 4 is based on a GSM-wireless scenario, for example comprising two radio cells and a base transceiver station disposed therein, in which a first base station BTS1 (transceiver) draws a first radio cell FZ1. The second base station BTS2 (transceiver) "illuminates" the second radio cell FZ2 in all directions, and from Figures 1 and 2 the base station BTS1, BTS2 is wireless over the air interface designed for the wireless scenario. Radio unidirectional or bi-directional uplink (UL) (uplink) for transmission channel (TRC) corresponding to mobile stations MS1 ... MS5 (transceiver) in cells FZ1, FZ2 And / or downlink (DL) (downlink) —shows a wireless scenario with channel multiple use according to frequency / time / code multiplex connected by communication. The base stations BTS1 and BTS2 are connected in a known manner (see GSM communication system) to a base station controller (BSC), which is managed and exchanged in the control category of the base station. Perform the function. A base station controller (BSC) is connected to a higher communication network, such as a Public Switched Telecommunication Network (PSTN) via a Mobile Switching Center. The mobile switching center (MSC) is the management station for the communication system shown. The mobile switching center performs complete call management and performs registration of communication subscribers and location monitoring in the network by means of registers (not shown).

FIG. 5 shows the configuration of base stations BTS1 and BTS2 formed of a transceiver, while FIG. 6 shows the configuration of mobile stations MS1 ... MS5 formed of a transceiver. Base stations BTS1 and BTS2 transmit and receive information from and to mobile stations MS1 ... MS5, while mobile stations MS1 ... MS5 transmit and receive information from and to base stations BTS1, BTS2. . For this purpose the base station comprises a transmit antenna (SAN) and a receive antenna (EAN), while the mobile stations (MS1 ... MS5) comprise an antenna (ANT) common to transmission and reception, controllable by an antenna switching connection (AU). do. The base stations BTS1 and BTS2 receive at least one information FN with a frequency / time / code component of at least one mobile station MS1 ... MS5, for example, via the receive antenna ANT in the upward direction (receive path). While receiving, the mobile stations MS1... MS5 have at least one information with frequency / time / code components of, for example, at least one base station BTS1, BTS2 via the common antenna ANT in the downward direction (receive path). Receive (FN). The information FN consists of a wideband extended carrier signal with modulated information consisting of data symbols.

Carrier signals received at the radio receiver (FEE) (receiver) are filtered, mixed and brought to an intermediate frequency. The intermediate frequency was sampled and quantized. After analog / digital conversion, the signal distorted by multipath propagation in the wireless path is fed to the equalizer. The equalizer compensates most of the distortion.

Then, in the channel estimator KS, the transmission characteristics of the transmission channel TRC for transmitting the information FN are evaluated. The transmission characteristics of the channel are represented by the channel pulse response over time. In order for the channel pulse response to be evaluated, the special additional information formed in the training information sequence on the transmitting side (in this case by the mobile station MS1 ... MS5 or the base station BTS1, (BTS2)) in the form of a so-called midamble. It is assigned to the information FN.

Then, in one data detector DD common to all the received signals, the signal components unique to the individual mobile stations included in the common signal are corrected and separated in a known manner. After correction and separation, data symbols are converted into binary data in a symbol / data converter (SDW). The original bit stream is then obtained from the intermediate frequency in the demodulator DMOD, and then in the demultiplexer DMUX individual time slots are assigned to the correct logical channel and accordingly to different mobile stations.

The bit sequence obtained in the channel codec KC is decoded according to the channel. Bit information is assigned to control and signaling time slots or voice time slots depending on the channel, and-in the case of a base station (FIG. 5)-control and signaling data and voice data for signaling and voice coding / for transmission to a base station controller (BSC). It is provided on one interface (SS) in charge of decoding (Sprach-Codec), while in the case of a mobile station (Fig. 6)-control and signaling of the control and signaling unit (STSE) in charge of complete signaling and control of the mobile station. Data and voice data are delivered to a voice codec (SPC) designed for voice input and output.

The voice data in the voice codec of the interface SS at the base stations BTS1 and BTS2 becomes a predetermined data stream (e.g., 64 kbit / s stream in the network direction or 13 kbit / s stream in the network direction).

In the control unit STE, complete control of the base stations BTS1 and BTS2 is made.

The base stations BTS1 and BTS2 transmit at least one information FN with the frequency / time / code components of at least one mobile station MS1 ... MS5, for example, via the transmit antenna SAN in the downward direction (transmission path). While transmitting, the mobile stations MS1 ... MS5 have at least one with a frequency / time / code component of, for example, at least one base station BTS1, BTS2 via a common antenna ANT in an upward direction (transmission path). Information (FN) is transmitted.

Since the transmission path starts at the base stations BTS1 and BTS2 in Fig. 5, the control and signaling data and voice data obtained through the interface SS from the base station controller BSC in the channel codec KC are controlled and signaled in time slots or voice. It is assigned to a time slot, which is coded into a bit sequence according to the channel.

Since the transmission path starts at the mobile stations MS1 ... MS5 in FIG. 6, the control and signaling data obtained from the voice codec (SPC) and the control and signaling unit (STSE) in the channel codec (KC) are controlled and controlled. It is assigned to a signaling time slot or voice time slot, which is coded into a bit sequence according to the channel.

The bit sequences obtained at the base stations BTS1 and BTS2 and the mobile stations MS1 ... MS5 are converted into data symbols by the data / symbol converter DSW. Then, each data symbol is extended by each subscriber individual code in the expansion device (SPE). In a burst generator (BG) consisting of a burst synthesizer (BZS) and a multiplexer (MUX), an extended data symbol of a training format sequence is added to the extended data symbol in the form of a midamble for channel evaluation and said multiplexer (MUX) The burst information obtained in the manner is set to the correct time slot. Then, the obtained burst is high frequency modulated and digital / analog converted in the modulator MOD, and then the signal obtained in the above manner is transmitted as the information FN via the transmitting antenna SAN or the common through the radio transmitting apparatus FSE (transmitter). Radiated from the antenna ANT.

A TDD communication system (Time Division Duplex) is a communication system in which a transmission time frame consisting of a plurality of time slots is preferably divided centrally for the downlink transmission direction (downlink) and the uplink direction (uplink).

TDD communication systems including the transmission time frame include, for example, known DECT systems [Digital Enhanced (formerly European) Cordless Telecommunication; Nachrichtentechnik Elektronik 42 (1992) January / February, No. 1, Berlin, DE; ETSI-Publikation ETS 300175-1 ... 9, October 1992 and DECT-Publikation des DECT-Forum, February 1997, pages 1-16, U. Pilger "Struktur des DECT-Standards", pages 23-29 ]

7 shows a DECT transmission time frame with a duration of 10 ms, consisting of 12 "downlink" time slots and 12 "uplink" time slots. For any two-way communication connection to a frequency scheduled in the downlink direction (downlink) and uplink direction (uplink), the "downlink" time slot (ZS _DOWN ) and the "uplink" time slot (according to the DECT-standard) ZS _up ), one empty time slot pair is selected. The interval between the "downlink" time slot (ZS _DOWN ) and the "uplink" time slot (ZS _UP ) in the time slot pair is half the length (5ms) of the DECT transmission time frame according to the DECT-standard.

A frequency division duplex (FDD) communication system is a communication system in which a transmission time frame consisting of a plurality of time slots is transmitted in a first frequency band in a downlink transmission direction (downlink) and in a second frequency band in an uplink direction (uplink). .

Paging Channel, RACH Channel (Random Access Channel), and TCH-Traffic Channel. Their function in the air interface is described, for example, in the publication Informatik Spektrum 14 (1991) June, No. 3, Berlin, DE; Regarding Publikation telekom praxis 4/1993, P.
