Accompanying drawing 4 has for example been represented for example to have two radio plots and has been arranged to have base station (transmission base station) therein on gsm radio communication plan basis, wherein first base station BTS 1 (transmitter receiver) makes first radio plot FZ1 and second base station (transmitter receiver) make second radio plot FZ2 omnirange " radiation ", with have channel from attached Fig. 1 and 2 according to the radio communication scheme of frequency division multiple access/TDMA/CDMA and repeatedly utilize, therein with base station BTS 1, BTS2 is through being the air interface of radio communication conceptual design and a plurality of radio plot FZ1 that is positioned at, mobile radio station MS1...MS5 (transmitter receiver) among the FZ2 is general by radio, perhaps two-way, on corresponding transmission channel TRC (transmission channel), be connected and can connect in the radio communication of up direction UL (uplink) and/or down direction DL (downlink).Base station BTS 1, BTS2 (see the GSM-radio communications system) and are connected with base station controller BSC (base station controller) that base station controller is born frequency management and function of exchange in a known manner in the control range of base station.Base station controller BSC is at its radio circuit that passes through mobile exchange station MSC (mobile switching centre) and upper level on the one hand, and for example PSTN (public switched communication network) is connected.Mobile exchange station MSC represents communication system administrative center.It is born whole call managers and has the integrator of grouping (not having expression) identification communication user and the monitoring of the orientation on network.

Accompanying drawing 5 has represented to constitute the base station BTS 1 of transmitter receiver, the theory structure of BTS2, and accompanying drawing 6 has represented to constitute equally the theory structure of the mobile radio station MS1...MS5 of transmitter receiver.Base station BTS 1, BTS2 bear from send to mobile radio station MS1...MS5 and receive message, and mobile radio station MS1...MS5 bear from send and receive radio message to base station BTS 1, BTS2.There are a transmitting antenna SAN and a reception antenna EAN in the base station for this reason, and mobile radio station MS1...MS5 has a common antenna ANT that can control transmission and receive by antenna switch AU.For example receive at least one from one of them mobile radio station MS1...MS5 at least at up direction (RX path) base station BTS 1, BTS2 through reception antenna EAN to have frequency/time/the radio message FN of coding composition, and mobile radio station MS1...MS5 at down direction (RX path) by common antenna ANT for example from least one base station BTS 1, BTS2 receives to have frequency/time/at least one radio message FN of coding composition.Wherein radio message FN is by the carrier signal of being made of information the data symbol modulation that has of broadband expansion.

Go up received carrier signal filtering and be mixed into an intermediate frequency at radio system FEE (receiver), this proceeds scanning and quantification on the one hand at it.After analog/digital conversion, will the major part of distortion be carried out balance (be called for short: synchronization) because the signal of multipath propagation distortion inputs to equalizer EQL on radio path.

Attempting transmitting the transmission characteristic of the transmission channel TRC of radio message FN subsequently in channel estimator KS thereon assesses.Wherein the transmission characteristic of channel responds explanation by the channel pulse string in time domain.If transmit leg (in the present circumstance from mobile radio station MS1...MS5 and from base station BTS 1, BTS2) is special with one, the additional information that constitutes the training information sequence is given with so-called mid portion form additional allocation and when being subordinated to radio message FN, thereby the response of channel pulse string can be assessed.

, the signal section that is included in the single mobile station special use in the common signal is revised with known method and separated to all received signals on the common data detector DD that detects subsequently.Convert binary data at the data symbol of revising and after separating will occur at present on symbol data transducer SDW.On the demodulation multiplexer DMUX single time slot allocation given correct logic channel and so also distribute to different mobile radio stations before, on demodulator DMOD, obtain original bit stream then from middle frequency.

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, if under the situation of base station (accompanying drawing 5), in order to check that to the base station controller BSC transmission data and signaling data and language data are transferred to the interface SS that is responsible for signaling and speech encoding/language decoder jointly, if and under the mobile radio station situation (accompanying drawing 6), will check that data and signaling data are transferred to the control unit of being responsible for whole signaling and mobile radio station control and signaling unit STSE and language data is transferred to the language codec SPC that designs into language input and language output.

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

On control unit STE, carry out the The whole control of base station BTS 1, BTS2.

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

Inspection data that obtain in the language data that begins on the mobile radio station MS1...MS5 and will obtain from language codec SPC on channel coding-decoder KC with from control unit and signaling unit STSE at transmit path on the accompanying drawing 6 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 thus.

At base station BTS 1, BTS2 with on each comfortable data symbol transducer DSW of bit sequence that mobile radio station MS1...MS5 obtains, convert data symbol to.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 BZS, 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 with 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.

By means of accompanying drawing 8 and 9 narration embodiments of the invention.

Accompanying drawing 8 has represented that from the time frame of accompanying drawing 1 to 3 with from the DECT transmission time frame of accompanying drawing 7 (improved) TDD time division multiple access frame ZMR has 8 time slot ZS ｀ 1...ZS ｀ 8, wherein preceding four time slot ZS ｀ 1...ZS ｀ 4 is arranged to be used for downlink transmission direction DL and back four time slot ZS ｀ 5...ZS ｀ 8 are arranged to be used for uplink direction UL.Just owing to the expression reason of accompanying drawing 9 channel assignment tables reduces to " 8 " and for the present invention not influence according to accompanying drawing 1 and 3 from " 16 " with the number of time slot.Opposite number of time slot, (for example coding, frequency etc.) can change arbitrarily more or less according to communication system as other physical resource.

Accompanying drawing 9 has been represented according to the channel assignment table that has frequency division multiple access composition, code division multiple access composition and time division multiple access composition channel on the accompanying drawing 8 time division multiple access frame bases.The time division multiple access composition of this table includes according to accompanying drawing 8 has the time slot ZS ｀ 1...ZS ｀ 8 that TDD distributes.The frequency division multiple access composition includes 12 frequency FR1...FR12, and the code division multiple access composition includes 8 codings (pseudo-random signal) C1...C8.

On first frequency FR1, will constitute the transmission path service of " bearer service ", the logic channel of communication system for example, as be used for the control channel of signaling, the AGCH channel, BCCH channel, PCH channel, the RACH channel, TCH channel and/or FACCH channel, these need in communication system down link direction and/or up direction, concentrate on the code plane by coding C1...C8 expansion.Prove that for above-mentioned communication system this is concentrated is suitable, because avoided time slot thus, i.e. unnecessary the taking of " time " resource.

Accompanying drawing 9 has been represented favourable form of implementation, according to this in that first selects time slot as fixing (agreement) predesignated on first time slot ZS of downlink transmission direction ｀ 1 on first frequency FR1, select time slot with (agreement) predesignated second that conduct on the 5th time slot ZS ｀ 5 of uplink direction is fixing, favourable is used for the concentrated of above-mentioned transmission path service with all coding C1...C8 separately.It would, of course, also be possible to be less than or, if can provide when using, also can utilize more coding more than eight codings.

On accompanying drawing 9 in the concentrating of expression, the C1...C8 that for example encodes distributes like this, the control channel and the AGCH channel that a coding are used for signaling, an other coding is used for BCCH channel and PCH channel and six codings of remainder are preserved and the TCH channels of gifting, and coding C1...C8 distributes like this, a coding is used for the RACH channel, an other coding is used to transfer the FACCH channel of indication and six codings of remainder TCH channel of still preserving and gift.

Can also continue to improve the performance of frequency spectrum benefit and/or communication system, if as shown in Figure 9 for different connectivity scenarios, will be separately physical resource " coding, frequency, time " communicate to connect when occupying first connectivity scenario VSZ1, second connectivity scenario VSZ2, the 3rd connectivity scenario VSZ3, the 4th connectivity scenario VSZ4 and the 5th connectivity scenario VSZ5 at the identical a plurality of two-way TDD different of downlink transmission direction with part with uplink direction part.For example communicate to connect to use first group of G1 that oblique hacures and declivity hacures represent and communicate to connect the second group of G2 that represents with the declivity hacures and be subordinated to each connectivity scenario VSZ1...VSZ5.Wherein each group includes at least one two-way communicating to connect.

The first group of G1 that communicates to connect in first connectivity scenario VSZ1 takies six codings-first C1 that encodes on second time slot ZS ｀ 2 at downlink transmission direction on second frequency FR2, second coding C2, the 3rd coding C3, the 4th coding C4, the 5th coding C5 and the 6th coding C6-and on the 6th time slot ZS ｀ 6 of downlink transmission direction, also take six coding C1...C6, and the second group of G2 that communicates to connect also takies first coding C1 taking on the 4th the time slot Z ｀ S4 at downlink transmission direction on second frequency FR2 on first coding C1 and the 8th time slot ZS ｀ 8 in the uplink direction.

The 4th time slot ZS ｀ 4 and second time slot ZS ｀ 2 are " down direction " time slot ZS _DOWN, and the 6th time slot ZS ｀ 6 and the 8th time slot ZS ｀ 8 are " up direction " time slot ZS _UP

For communicating to connect at " down direction " time slot ZS in each that organize on G1, the G2 _DOWN" up direction " time slot ZS _UPBetween first distance A S1, according to prior art (seeing accompanying drawing 7), be the length of half time division multiple access frame ZMR.Therefore distance A S1 is a mark of time division multiple access frame ZMR length, and this moment, the numerical value of mark was 0.5.

The first group of G1 that communicates to connect in second connectivity scenario VSZ2 also takies six coding C1...C6 taking on the 4th the time slot ZS ｀ 4 at downlink transmission direction on the 4th the frequency FR4 on six codings C1...C6 and the 7th the time slot ZS ｀ 6 in the uplink direction, and the second group of G2 that communicates to connect takies first coding C1 and second coding C2 taking on second time slot ZS2 at downlink transmission direction on the 4th the frequency FR4 on coding C1...C4 and the 5th the time slot ZS ｀ 5 in the uplink direction.

The 4th time slot ZS ｀ 4 and second time slot ZS ｀ 2 are " down direction " time slot ZS _DOWN, as on first connectivity scenario VSZ1, and the 7th time slot ZS ｀ 7 and the 5th time slot ZS ｀ 5 are " up direction " time slot ZS _UP

For communicating to connect at " down direction " time slot ZS in each that organize on G1, the G2 _DOWN" up direction " time slot ZS _UPBetween the length of second distance A S2 be a mark (distance of part) of time division multiple access frame ZMR length, this moment, the size of mark was fixed for being greater than or less than 0.5, the second distance A S2 of numerical value.

Taking four coding C1...C4 and on the 5th frequency FR5, taking six coding C1...C6s and seven coding C7 and eight coding C8 at the 8th time slot ZS ｀ 8 in the uplink direction at second time slot ZS ｀ 2 of downlink transmission direction on the 6th the frequency FR6 at downlink transmission direction at first group of G1 that the 3rd connectivity scenario VSZ3 communicates to connect, and second group of G2 of communication connection taking coding C1...C3 and taking coding C1...C4 at the 5th time slot ZS ｀ 5 in the uplink direction on the 5th frequency FR5 at the 3rd time slot ZS ｀ 3 on the 6th the frequency FR6 at downlink transmission direction.
