Accompanying drawing 5 has represented to constitute the base station BTS 1 of transmitter receiver, the principle knot of BTS2 Structure, and accompanying drawing 6 has represented to constitute equally the movement station MS1 of transmitter receiver ... MS5's Theory structure. Base station BTS 1, BTS2 bear from and to movement station MS1 ... the MS5 sending and receiving Message, and movement station MS1 ... MS5 bears from and to base station BTS 1, BTS2 sending and receiving not to be had Line electricity message. There are a transmitting antenna SAN and a reception antenna EAN in the base station for this reason, and moves Moving station MS1 ... MS5 has the public affairs that can control sending and receiving by antenna switch AU Use antenna ANT. At up direction (RX path) base station BTS 1, BTS2 process reception antenna EAN is for example at least from one of them movement station MS1 ... MS5 receives at least one and has frequency/time Between/the radio message FN of coding composition, and movement station MS1 ... MS5 (receives at down direction The path) pass through common antenna ANT for example from least one base station BTS 1, BTS2 receives to have frequently At least one radio message FN of rate/time/coding composition. Wherein radio message FN is The carrier signal that is formed information by the data symbol modulation that has by the broadband expansion.

Upper with received carrier signal filtering and mixed at radio system FEE (receiver) Synthetic intermediate frequency, this proceeds scanning and quantification on the one hand at it. At analog/digital Will be because the signal of multipath propagation distortion inputs to balanced device on radio path after the conversion EQL carries out balance with the major part of distortion and (is called for short: synchronization).

In channel estimator KS, attempt subsequently transmitting the transmission letter of radio message FN thereon The transmission characteristic of road TRC is assessed. Wherein the transmission characteristic of channel is by letter in time domain Road train of pulse response explanation. If transmit leg is (in the present circumstance from movement station MS1 ... MS5 And from base station BTS 1, BTS2) with one special, constitute the additional of training information sequence Radio message FN is given and be subordinated to information with so-called mid portion form additional allocation The time, thereby the response of channel pulse string can be assessed.

, will be included on the common data detector DD that detects all received signals subsequently The signal section of the single mobile station special use in the common signal is revised with known method and is divided From. In the data symbols of revising and after separating will occur on symbol data converter SDW at present Number convert binary data to. Give single time slot allocation correct at demodulation multiplexer DMUX Logic channel with therefore also distribute to different movement stations before, then on demodulator DMOD from Intermediate frequency obtains original bit stream.

On channel-codec KC, the bit sequence that obtains is decoded with the channel mode. With bit information according to channel allocation give to check time slot and signalling time slot or language time slot and, as Fruit in the situation of base station (accompanying drawing 5), for will check to base station controller BSC transmission data with Signaling data and language data are transferred to jointly is responsible for connecing of signaling and speech encoding/language decoder Mouth SS will be and if in the movement station situation (accompanying drawing 6), will check that data and signaling data pass Be defeated by control module and the signaling unit STSE that is responsible for whole signaling and movement station control and will speak The speech transfer of data is given the language codec SPC for language input and language output design.

On the language codec of interface SS on base station BTS 1, the BTS2, language data is become For the data flow predesignated (for example in network side to for 64Kbit/s-stream and from network side To being 13kbit/s-stream).

Carry out the whole control of base station BTS 1, BTS2 at control module STE.

Down direction (transmit path) base station BTS 1, BTS2 through transmitting antenna SAN for example to the major general have frequency/time/a radio message FN of coding composition sends to mobile radio station MS1 at least ... among the MS5 one, and mobile radio station MS1 ... MS5 up direction (transmit path) through common antenna ANT for example to the major general have frequency/time/a radio message FN of coding composition sends at least one base station BTS 1, BTS2.

Distribute in the inspection data that begin on base station BTS 1, the BTS2 and on channel coding-decoder KC, will obtain through interface SS from base station controller BSC and signaling data and language data at transmit path on the accompanying drawing 5 thus and check time slot and signalling time slot or language time slot and these are encoded in the channel mode and become bit sequence.

Transmit path is at mobile radio station MS1 on accompanying drawing 6 thus ... language data that begin on the MS5 and that will obtain from language codec SPC on channel coding-decoder KC and the inspection data that obtain from control unit and signaling unit STSE and signaling data are distributed to and are checked time slot and signalling time slot or language time slot and these are encoded in the channel mode and become bit sequence.

At base station BTS 1, BTS2 with at mobile radio station MS1 ... convert data symbol on each comfortable data symbol transducer DSW of the bit sequence that MS5 obtains.Separately the data symbol coding that each personal user is special on expanding unit SPE is expanded then.On the pulse series generator BG that constitutes by pulse train combination device BZS and multiplexer MUX, on pulse train combination device BZS1, separately a training information sequence is added to the pulse string information that is used for channel estimating on the expanded data symbol and will obtains in this way with the form of mid portion on multiplexer MUX then and be arranged on correct separately time slot.The signal that obtains in this way is transmitted into before transmitting antenna SAN and the common antenna ANT through radio transmission apparatus FSE (transmitter) as radio message FN, at last be modulated into high frequency on each the comfortable modulator MOD of pulse train that obtains and carry out the digital-to-analog conversion.

TDD communication system (time division multiple access) is a communication system, is split up into downlink transmission direction (downlink) and uplink direction (uplink) in the middle of the transmission time frame that is made of a plurality of time slots is preferably in therein.

The TDD communication system that this transmission time frame is arranged for example is that [numeral strengthens (in the past: Europe) radio communication in known DECT system; See 42 (1992) 1/2 months 1 volumes of message technology electronics, Berlin, DE; U.PILGER " structure of DECT-standard ", 23 to 29 pages and ETSI-publication ETS300175-1 ... 9, the DECT-publication of October 1992 and DECT-plenary session interrelates in 1997,1 to 16 pages of February].

Accompanying drawing 7 has represented to have the DECT transmission time frame that the time cycle is 10ms, is made up of 12 " down direction " time slots and 12 " up direction " time slots.Be connected for two-way communication arbitrarily on the frequency of predesignating and select to have " down direction " time slot ZS according to dect standard at downlink transmission direction DL (downlink) and uplink direction UL (uplink) _DOWN" up direction " time slot ZS _UPThe time slot pair of free time, therein at " down direction " time slot ZS _DOWN" up direction " time slot ZS _UPBetween distance be half of DECT when transmission frame length equally according to dect standard.

FDD transmission system (frequency division multiple access) is a radio transmission system, the time frame of forming by a plurality of time slots therein, downlink transmission direction (downlink) be transmitting on first frequency band and transmit on second frequency band in uplink direction (uplink).

With the FDD communication system that time frame transmits in this way, for example be that known gsm system [moves or global system for mobile communications in groups; See 14 (1991) June of information spectroscopy, No. 3, Berlin, DE; A.Mann: " GSM-standard-European digital mobile radio network foundation ", communicate by letter with publication for 137 to 152 pages and put into practice 4/1993, P.Smolka " GSM-radio interface-element and function ", 17 to 24 pages interrelate].

The air interface understanding of GSM-system much is called as the logic channel of transmission path service (bearer service), AGCH channel (permission access channel) for example, BCCH channel (wide search channel), FACCH channel (fast associated control channel), PCH channel (paging channel), RACH channel (direct access communications channels) and TCH channel (traffic channel), its separately function on air interface for example is described in 14 (1991) June of documentation ﹠ info spectroscopy, No. 3, Berlin, DE; A.Mann: " GSM-standard-European digital mobile radio network foundation ", communicate by letter with publication for 137 to 152 pages and put into practice 4/1993, P.Smolka " GSM-radio interface-element and function ", 17 to 24 pages interrelate].

Because (mobile radio of the 3rd generation and IMT-2000) should come into operation WCDMA/FDD operation and TDCDMA/TDD operation jointly in UMTS-scheme framework, effective transition with logic channel and transmission path service (carrying processing) waits in expectation on the air interface of the communication system of the radio communication between the transmitter receiver that moving and/or fixing on code division multiple access and the time division multiple access basis.
