In recent years, along with the development of radio communication system base station designing technique, wireless device control (REC) node and wireless device (RE) node in the radio base station trend towards physical separation, for example, the RE node can be near antenna, and the REC node is positioned at is convenient to access place.The REC node is carried out base band signal process, and each RE node is changed between base band and radio frequency, and by one or more antenna emissions or reception information.The REC node is by independently dedicated optical links and/or current source road are connected with a plurality of long-range RE nodes.Each link from the REC node to the descending transmission data of RE node, from the RE node to REC node uplink data.
Data mutual between REC node and the RE node comprise user data and control data.Wherein, user data is meant the user's operating data that is sent to subscriber equipment (or be sent to radio base station from subscriber equipment) from radio base station.User data is pressed plural form and is transmitted, and therefore claims that also the user data of plural form is the IQ data, and wherein " I " corresponding to the real part or the in-phase component of complex signal, and " Q " is corresponding to the imaginary part or the quadrature component of complex signal.Via a physical I r link, can send several IQ data flow, each IQ data flow is corresponding to the data of an antenna (being called antenna carrier (AxC)) of a carrier wave.An AxC is relevant with the amount of user data that an antenna that passes through a carrier wave receives or sends.
Control data mutual between REC node and the RE node comprises: operation maintenance data (C﹠amp; The M data), synchrodata, identification data (as frame number).Wherein, operation maintenance data (C﹠amp; The M data) be used for the communication interface between REC node, RE node, REC node and the RE node is carried out Operations,Administration And Maintenance, comprise polytype data such as parameter configuration class message, condition managing class message, alarm management class message, version management class.When synchrodata is meant interaction data between REC node and the RE node synchronously and timing information, can be used to detect the border of super group, frame and correlation number.Can be multiplexed on the Ir link by IQ data and the synchrodata of Time Division Multiplexing mode the different antennae carrier wave.Identification data is used for frame of unique identification.
Mutual in order to realize REC node and RE data between nodes, at Wideband Code Division Multiple Access (WCDMA) (WCDMA) system general public wave point (CPRI:Common Public RadioInterface) agreement has been proposed, in this agreement, the RE node utilizes a plurality of antenna carrier, receive or the transmission data by radio frequency interface, the REC node is separated with the RE node and is connected by transmission link.The control data and the user data that generate carry out between REC node and RE node by transmission link alternately.Wherein, user data comprises a plurality of data flow, the data of single carrier wave on the corresponding individual antenna of each data flow.Control data and user data are by the synthetic Time Division Multiplexing frame of time division multiplexing mode.
The internodal interface circuit speed of regulation REC node and RE is 614.4Mbps, 1.2288Gbps or 2.4576Gbps in the CPRI agreement.Line speed at 1.2288Gbps, and employing frame structure as shown in Figure 1, as can be seen from Figure 1, the basic frame of a TDM is made up of 16 words, each word accounts for the 16bit position, in the basic frame, first word (16bit) is used for transmitting control data, and remaining word is used for transmitting user data.In addition, as shown in Figure 2, a basic frame comprises 16 * 16=256bit, is combined into the superframe of a TDM by 256 basic frames, is combined into a WCDMA radio frames by 150 superframes.

Embodiment
Below in conjunction with Figure of description the embodiment of the invention is elaborated.
In the TD-SCDMA system, a TD-SCDMA frame is made up of two TD-SCDMA subframes, as shown in Figure 3, TD-SCDMA subframe includes business time-slot (TS0～TS6), uplink pilot time slot (UpPTS), descending pilot frequency time slot (DwPTS) and protection be (GP) at interval; Wherein, downlink business time slot and descending pilot frequency time slot are used to transmit downlink data, are called descending time slot; Uplink service time slot and uplink pilot time slot are used to transmit upstream data, are called ascending time slot.
Based on the design feature of above-mentioned TD-SCDMA subframe, in the embodiment of the invention, consider that data mutual between REC node and the RE node are carried out part separates and transmit.Concrete processing is as follows:
In data mutual between REC node and the RE node, the operation maintenance data in the control data separates transmission with other control data.The REC node transmits the downstream operation service data to the RE node in the ascending time slot of TD-SCDMA subframe; The RE node transmits the upstream operation service data to the REC node in the descending time slot of TD-SCDMA subframe.Wherein, can pass through the interactive interfacing data between REC node and the RE node, as can be used for the interface of interaction data between REC node and the RE node by Ir interface or other.
After operation maintenance data isolated from control data, the REC node utilized the descending time slot of TD-SCDMA subframe, transmitted down user data and other control data except that operation maintenance data to the RE node, as synchrodata and identification data (frame number); The RE node utilizes the ascending time slot of TD-SCDMA subframe, transmits uplink user data and other control data except that operation maintenance data to the REC node, as synchrodata and identification data.
In control data mutual between REC node and the RE node, operation maintenance data accounts for very big proportion in the The whole control data, therefore, utilize and above-mentionedly operation maintenance data is isolated from control data and separated the embodiment method that transmits at uplink and downlink timeslot with other control data, can make between REC node and the RE node when interaction data, the proportion of control data declines to a great extent in the TD-SCDMA subframe, thereby make more time slot be used to transmit user data, when therefore each data flow in user data adopts the sampling of 16bit position, can make the number of the data flow of transmitting user data reach 24, satisfy 3 sector/carrier waves in the TD-SCDMA system, every sector/carrier wave uses the demand of the smart antenna application scene of unit 8.
A TD-SCDMA frame can be made up of super group of a plurality of TDM, can be made up of the group of a plurality of TDM for super group of a TDM.As shown in Figure 4, group with an instantiation of the component relationship of TD-SCDMA frame is, is combined into a TDM super group (Z represents frame number by variable) by 64 groups (representing frame number by variable X), surpasses by 200 to be combined into a TD-SCDMA frame.In the enforcement, a super group takies 50 microsecond durations, and a TD-SCDMA frame takies 10 milliseconds of durations.
An instantiation is in the TD-SCDMA subframe, to utilize Ts1 and UpPTS to transmit descending C﹠amp; M Data utilizes Ts0 and DwPTS to transmit up C﹠amp; M Data.
For descending, total (864+160) * 768 bit/768 bits=1024 Group can be used as Control plane.Among the embodiment, give 1024 subchannels with downstream operation maintenance class data allocations.Each subchannel is made up of the Group that comprises 768 bits, and the composition of each Group as shown in Figure 5.
For up, (864+96) * 768 bit/768 bits=960 Group can be used as Control plane.Among the embodiment, give 960 subchannels with upstream operation maintenance class data allocations.Each subchannel is made up of the Group that comprises 768 bits, and the composition of each Group as shown in Figure 5.
Among Fig. 5, the shared size of data of four generic operation service datas (parameter configuration class message, condition managing class message, alarm management class message, version management class message) and reserved (reservation) is a signal, concrete shared neglect the needs in the real network greatly and decides.
In addition, because initial synchronisation needs synchronization character continuous, therefore the initial synchronisation data are placed on C﹠amp; In the M Data.
As shown in Figure 6, the group of a TDM frame is made up of 24 words, and each word accounts for the 32bit position, and a group comprises 24 * 32=768bit.Different with the frame structure of CPRI agreement in the prior art, the embodiment of the invention is after isolating operation maintenance data from control data, in a group, need not with the long control data that transmits except that operation maintenance data of a word (16bit), and can be with the control data except that operation maintenance data, as synchrodata, identification data (frame number) boil down to 1bit, take a lowest order in the word, and remaining bit can be used for transmitting user data, makes the ratio of user data in whole group great by raising.
The bit that dash area shown in Figure 6 takies for the control data of transmission except that operation maintenance data.Because this bit is arranged in the significant bits of whole group of lowest order byte, therefore, it is very little that it transmits influence for user data of whole group, and approximate can be considered is used to transmit user data with whole group, thereby the speed of radio base station data streams is obviously accelerated.
Among Fig. 6, each Group is made up of 24 words, and index is W=0...23.The byte number that comprises among each word represents that with T each word is corresponding to octet, and the bit in each byte is represented with B=0......7.The value of T depends on aggregate date rate, and this aggregate date rate is called as the Ir line bit rate.The total length of word is 32bit in this example, and promptly the value of T is 4, and obtainable data transfer rate is 1228.8Mbps.Utilize in can word of addressing everybody of index B and index T.B=0 wherein, T=0 is a lowest order.First bit that will have the word of index W=0 is used as control word, first bit of first word that is each Group is promptly X.0.0 as Start of Super-Group, SGN and BFN (synchrodata and identification data), and the remaining bits among the basic Group is used to transmit user data.
A plurality of transmission sequence is represented on the right side of Fig. 6 with the direction of arrow.If represent each bit from the low level to a high position in the byte, behind the 8B/10B coding, begin ten code characters " ABCDEI FGHJ " are sent as serial data stream from " A " with " ABCDEFGH ".Promptly in the 8B/10B coding, a bits of coded is added in three highest orders, another bits of coded is added in five lowest orders.
Certainly, the situation that control data except that operation maintenance data shown in Figure 6 takies 1bit only is an instantiation in the embodiment of the invention, in the embodiment of the invention, also can make control data except that operation maintenance data take the significant bits of other word in the group, for example, the significant bits of choosing different words in group successively is used for the transmission of the control data except that operation maintenance data.Certainly, the sum of the significant bits of the shared word of control data in group except that operation maintenance data can not surpass (15bit), this is because after taking 16bit, the word that transmits user data in group can only have 15, also can't satisfy 3 sector/carrier waves in the TD-SCDMA system this moment, every sector/carrier wave uses the demand of the smart antenna application scene of unit 8.
Based on above-mentioned situation, can one threshold value be set according to user's request and system capability, the sum of the significant bits of the shared word of control data in group except that operation maintenance data must not surpass this threshold value, to satisfy 3 sector/carrier waves in the TD-SCDMA system, every sector/carrier wave uses the demand of the smart antenna application scene of unit 8.Certainly, this threshold value must not surpass 15.
Corresponding 64 subchannels of super group, the control word index (Ns) of from 0 to 63, one subchannel of the index range of subchannel has four probable values--and 0,1,2 and 3.By equation X=Ms+16 * Ns to the control word index in the excess of export group.
The synchronization suchannel of each super group as shown in Figure 7.Wherein, synchrodata arrives the 7th control word of Ms=7 and Ns=0 corresponding to the 0th control word at Ms=0 and Ns=0 place.As mentioned above, by the synchrodata that comprises in this control word of RE node detection realize between REC node and the RE node synchronously and regularly.The least-significant byte of SGN is corresponding to the 16th control word at Ms=0 and Ns=1 place the 23rd control word to Ms=7 and Ns=1 place, and the most-significant byte of SGN arrives the 39th control word of Ms=7 and Ns=2 corresponding to the 32nd control word at Ms=0 and Ns=2 place.The least-significant byte of BFN is corresponding to the 8th control word at Ms=8 and Ns=0 place the 15th control word to Ms=15 and Ns=0, and the 24th control word at the most-significant byte of BFN and Ms=8 and Ns=1 place arrives the 31st control word of Ms=15 and Ns=1.Other control words are all as reserved.
In the enforcement, be multiplexed on the Ir link by user data, synchrodata, the identification data of Time Division Multiplexing mode with the different antennae carrier wave.Because synchrodata, identification data only take the significant bits of word in the group, therefore can under the prerequisite that does not influence the user data quality, realize synchronously and timing.
