4 is based on a GSM-wireless scenario, for example, comprising two radio cells and a base transceiver station disposed therein, wherein 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 stations BTS1, BTS2 are designed for the radio scenario and the radio cell FZ1 ), Wireless one-way or two-way uplink (UL) for the corresponding Transmission Channel (TRC) via a radio interface with a plurality of mobile stations MS1 ... MS5 (transceiver device) at (FZ2) And / or downlink (DL)-illustrates 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 telecommunication network, such as a Public Switched Telecommunication Network (PSTN), via a Mobile Switching Center (MSC). The mobile switching center (MSC) is the management station for the communication system shown. The mobile switching center performs complete call management and authenticates the communication subscribers and monitors the position in the network via registers (not shown).

FIG. 5 shows a general configuration of base stations BTS1 and BTS2 formed of a transceiver, while FIG. 6 shows a general configuration of mobile stations MS1 ... MS5 formed of a transceiver. Base stations BTS1 and BTS2 transmit and receive wireless messages to and from mobile stations MS1 ... MS5, while mobile stations MS1 ... MS5 transmit and receive wireless messages from and to base stations BTS1, BTS2. Send and receive 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 are at least one radio message FN with the frequency / time / code components of at least one mobile station MS1 ... MS5, for example, via the receive antenna ANT on the uplink (receive path). The mobile stations MS1 ... MS5 have at least one with frequency / time / code components of, for example, at least one base station BTS1, BTS2 via a common antenna ANT on the downlink (receive path). Receive a wireless message (FN). The radio message (FN) consists of a carrier signal spread over a wideband 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 is sampled and quantized. After analog / digital conversion, the signal distorted by multipath propagation in the radio path is fed to the equalizer. The equalizer compensates most of the distortion (Stw .: synchronization).

Then, in the channel estimator KS, the transmission characteristic of the transmission channel TRC for transmitting the radio message FN is 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. Assigned to a wireless message (FN).

Then, in one data detector DD common to all the received signals, the individual mobile station specific signal components included in the common signal are equalized and separated in a known manner. After equalization and separation, the data symbols so far present in the symbol / data converter (SDW) are converted to binary data. 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 obtained bit sequence is decoded according to the channel in the channel codec KC. Bit information is allocated 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 the base station controller (BSC). Provided in common to one interface (SS) responsible for decoding (Sprach-Codec), while in the case of a mobile station (FIG. 6) control of the control and signaling unit (STSE) responsible for complete signaling and control of the mobile station. And signaling data and voice data are delivered to a voice codec (SPC) designed for voice input / 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 are at least one radio message FN with a frequency / time / code component of, for example, at least one mobile station MS1 ... MS5 via the downlink (transmission path) transmit antenna SAN. The mobile stations MS1 ... MS5, on the uplink (transmission path), have at least one frequency / time / code component of, for example, at least one base station BTS1, BTS2 via a common antenna ANT. Send one wireless message (FN).

Since the transmission path starts at the base stations BTS1 and BTS2 in FIG. 5, the control and signaling data and the voice data obtained from the base station controller BSC through the interface SS in the channel codec KC are controlled and signaled at the time slot 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 voice data obtained from the voice codec SPC at the channel codec KC and the control and signaling data obtained from the control and signaling unit STSE are controlled. And a signaling time slot or voice time slot, which are 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 spread by each subscriber individual code in a spreading device (SPE). Then in the burst synthesizer (BZS) of the burst generator (BG) consisting of a burst synthesizer (BZS) and a multiplexer (MUX), the spread data symbols of the training format sequence are spread in the form of a midamble for channel evaluation. The burst information added to and obtained in this manner in the multiplexer (MUX) 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 this manner is transmitted as a wireless message FN via the transmitting antenna SAN or the transmitting antenna SAN. Emitted from a common 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 and 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.

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.

FR12). Or the interval AS2 ... AS5 between the "downlink" time slot (ZS ' _DOWN ) and the "uplink" time slot (ZS' _UP ) assigned to different carrier frequencies (FR1 ... FR12) is a time multiplier. And is selected to be part of a flex frame (ZMR) length, wherein the spacings AS2 ... AS5 are fixed or variable. A method for controlling a communication connection in a wireless communication system based on code and time division multiplex between mobile and / or fixed transceivers, the method comprising: Communication system by dividing each of the predetermined carrier frequencies FR1, ..., FR12 into a plurality of time slots ZS'1, ..., ZS'8 having a predetermined time slot duration T _ZS . It is possible to operate in the TDD mode or the FDD mode, and thus the mobile transceiver unit MS1, ..., MS5 within the time slot (ZS'1, ..., ZS'8) or the carrier frequency range. A maximum predetermined number of bidirectional communication connections between the communication subscribers and / or the fixed transmitting and receiving devices BTS1 and BTS2 may be simultaneously established through the uplink and the downlink, and the time slots ZS'1, ..., ZS'8 forms one time multiplex frame (ZMR) for each of the carrier frequencies FR1, ..., FR12, and subscriber signals to be transmitted within the time slot or frequency range are individually assigned to subscribers. In the method that is detachably coupled to the pseudorandom signal (C1, ..., C8) In the uplink and / or downlink, a transmission path service which is required in a communication system and formed as a "bearer service" is bundled in one code plane spread by the pseudorandom signals C1 ... C8. How to. The method of claim 6, A portion of the logical channels of the communication system, such as a control channel for signaling, an AGCH channel, a BCCH channel, a PCH channel, a RACH channel, a TCH channel and / or a FACCH channel, are bundled in the code plane as a transmission path service. Way. The method according to claim 6 or 7, The bundling in a first selection time slot (ZS'1) on downlink and in a second selection time slot (ZS'5) on uplink. The method of claim 8, The first time slot ZS'1 of the time slots ZS'1 ... ZS'8 is allocated to the first selection time slot ZS'1, and the second time slot ZS'5 is assigned to the second selection time slot ZS'5. And a fifth time slot (ZS'5) of time slots (ZS'1 ... ZS'8) is assigned. The method according to claim 6 or 7, In TDD mode, a pair of time slots, "downlink" time slot (ZS ' _Down ) and "uplink" time slot (ZS' _up ), for each communication connection are the same carrier frequency (FR1 ... FR12). Or the interval AS2 ... AS5 between the "downlink" time slot (ZS ' _DOWN ) and the "uplink" time slot (ZS' _UP ) assigned to different carrier frequencies (FR1 ... FR12) is a time multiplier. And selected to be part of a flex frame (ZMR) length, wherein the spacings AS2 ... AS5 are fixed or variable.
