Description
Technical field
The present invention relates to the digital mobile communication technical field, relate in particular to a kind of data parallel dispatch system and method for in third generation time division SCDMA (TD-SCDMA) system, supporting the down high speed grouping access of multicarrier.
Background technology
A disequilibrium that important feature is the traffic carrying capacity of professional uplink and downlink link of 3-G (Generation Three mobile communication system), the traffic carrying capacity of down link will general traffic carrying capacity greater than up link.At this demand, 3GPP (3rd Generation Partnership Project, third generation collaborative program) has introduced HSDPA (High Speed Downlink Packet Access, high speed downlink packet inserts) characteristic in the 3G standard.
In the HSDPA characteristic, by introducing AMC (Adaptive Modulation and Coding, adaptive coding and modulating), HARQ (Hybrid Automatic Retransmission Request, mix automatic repeat requests) technology and the relevant technology that reduces the network processes time delay, the downlink grouping traffic speed of higher rate is provided, improves spectrum utilization efficiency.
HARQ is a kind of error correction method that traditional ARQ (Automatic Retransmission Request, automatically repeat requests) technology and FEC (Forward Error Correct, forward error correction) technology are combined.The sign indicating number that transmitting terminal sends not only can detect mistake, but also has certain error correcting capability.
In the HSDPA technology, HS-DSCH (High Speed Downlink SharedChannel, high speed descending sharing channel) and MAC-hs (high speed media access control) sublayer have newly been introduced.Realize in Node B at network side MAC-hs, be used for carrying out the transfer of data of HS-DSCH transmission channel.In Node B, each sub-district has a MAC-hs entity (entity), and MAC-hs not only finishes HS-DSCH data processing and scheduling, is in charge of the management and the distribution of HSDPA physical resource simultaneously.MAC-hs comprises that flow control, scheduling/priority control, HARQ function, TFRC select functional entitys such as (Transport Format and Resource Choice, transformat and resource selection).In the MAC-hs entity of Node B side, the corresponding HARQ entity of each UE (subscriber equipment), carry out N-Channel SAW (See And Wait) Protocol (N channel stop-and-wait protocol), what promptly this HARQ entity was carried out is the N-channel-SAW-HARQ agreement.A HARQ entity is corresponding to a plurality of HARQ processes, and in the agreement of present 3GPP about TD-SCDMA, the HARQ entity of a UE can comprise 8 HARQ processes (process) at most, and different HARQ processes identifies by process ID (process number).The corresponding HARQ process of HS-DSCH TTI.In the UE side, MAC-hs entity of a UE comprises the HARQ function, distributes, reorders and the decomposition function entity.HARQ entity wherein and the HARQ entity among the Node B are peer-entities, the HARQ process that comprises similar number, each process forms protocol entity one to one by the process of process Id and Node B side, is used for the reception of MAC-hs PDU (protocol Data Unit) packet.If the data of the reception that receiving terminal is correct, up HS-SICH channel (high-speed shared information channel) feeding back ACK signal then by describing below, the HARQ process of Node B side discharges this packet.Otherwise, if fail correct the reception, the buffer memory soft data, and by HS-SICH feedback NAK signal, the transmitter side process is retransmitted this packet, promptly HARQ entity handles MAC-hs PDU packet retransmits and is undertaken by process.
In TD-SCDMA system HSDPA technology, the new HS-DSCH transmission channel of introducing is mapped on the HS-PDSCH (High Speed Physical Downlink Shared Channel, high-speed physical downlink is shared physical channel) of new introducing.The HS-PDSCH channel is that a plurality of users share in the mode that time-division or sign indicating number divide in the sub-district.The Transmission Time Interval TTI of HS-PDSCH (Transmission TimeInterval) is 5ms.HS-PDSCH carrying be user's business datum, transmit and be used for phase related control information that HS-PDSCH the receives HS-SCCH that follows (High-Speed Shared Control Channel) by new introducing, HS-SICH is used for the transmission of uplink feedback information.Therefore, these three kinds of physical channels are formed a physical layer closed loop, and they all are that the TTI of 5ms is that unit handles and transmits, and this short TTI is the time-varying characteristics of adaptive radio link better.Wherein the control information of carrying on the HS-SCCH channel comprises: HARQ Process ID, redundancy versions, New Data Flag, HS-SCCH cyclic sequence HCSN, UE ID, modulation system MF, transmission block size sign and physical channel resources; The carrying feedback information comprises on the HS-SICH channel: the correct transmission of the modulation system RMF of recommendation, the transmission block of recommendation size RTBS and data is confirmation ACK/NAK whether.In addition, for the transmission of RRC signaling, 3GPP has also defined the accompanied by physical channel of up-downgoing in R5, is used to carry the relevant RRC signaling with HSDPA.
Comparatively speaking, the TD-SCDMA system provides user's peak rate on the low side on single carrier wave, and reason is that the frequency spectrum of single carrier frequency is narrow in the system, only is 1.6MHz.Do not change under the situation of spectrum efficiency, single user 2.8Mbps is provided above peak rate, expanding frequency range is effective means.TD-SCDMA multi carrier wave high-speed downlink packet access technique just is being based on this thinking and is proposing.
When using the HSDPA technology, a plurality of carrier wave upper signal channel resources can that is to say that this user can receive the information that a plurality of carrier waves in this sector send simultaneously for same user's service.In theory, the N carrier system can make N that the user obtains original speed doubly.
There is multiple implementation in TD-SCDMA multi-carrier HSDPA system, and one of them is based on existing 3GPP R5 framework, sends data flow and assigns to each carrier wave at the MAC-hs layer, finishes physical treatment then independently of one another, sends by air interface.Receiving terminal, UE at first receive the data of a plurality of carrier waves, finish each carrier signal demodulation, decoding then, afterwards data are sent to MAC-hs and merge.This has the parallel dispatching of multicarrier with regard to the MAC-hs that requires transmitter side, and promptly MAC-hs dispatches the ability of a user's data of a plurality of carrier wave parallel transmissions in same TTI.
Therefore, how based on above-mentioned TD-SCDMA multi-carrier HSDPA scheme, propose a kind of data parallel dispatch system and method for supporting that the multi carrier wave high-speed downlink grouping inserts, solve data parallel dispatch problem in the multi-carrier HSDPA system, become problem demanding prompt solution in the industry.

Fig. 2 is the schematic diagram according to the data parallel dispatch system of the described multi-carrier HSDPA of embodiments of the invention, between transmitter and the receiver by a plurality of carrier transmission user data.In sending part parallel scheduling entity 100, include transmitting terminal control (Controller) module 101, PDU formats (PDU Formatting) module 102, data distribution (Packet Diverting) module 103, the transmitting terminal multicarrier mixes automatic repeat requests (multi-carrier HARQ, MC HARQ) module 104, in the parallel scheduling entity 200 of receiving unit, comprise receiving terminal control (Controller) module 201, separate format (De-formatting) module 202, data (Packet Conflux) module 203 of confluxing, the receiving terminal multicarrier mixes automatic repeat requests (MC HARQ) module 204.
Wherein, transmitting terminal control module 101 is used at transmitting terminal each user's high-speed data-flow being assigned to one or more carrier waves according to the size of each amount of user data, and by the parallel scheduling to a plurality of carrier waves user data is sent through physical layer; PDU formatting module 102 is used under the control of described control module, according to the Radio Link situation of feeding back on each carrier wave, with the packet with set form of described user data formation corresponding to each specific carriers; Data distribution module 103 is used under the control of described control module, will be assigned to respectively by the packet that described protocol Data Unit formatting module forms on the corresponding carrier wave; The transmitting terminal multicarrier mixes automatic repeat requests module 104, be used under the control of described control module, be sent to separately the automatic repeat requests entity of mixing respectively with being assigned to packet on each carrier wave, walk abreast and mix automatic repeat requests scheduling, finish the transmission control that mixes automatic repeat requests agreement;
Receiving terminal control module 201, be used for receiving terminal control carry out each carrier data reception, converge and submit to; The receiving terminal multicarrier mixes automatic repeat requests module 204, is used under the control of described control module, finishes the reception control of the automatic repeat requests agreement of mixing of the packet on each carrier wave; Data confluence module 203 is used under the control of described control module, finishes the rearrangement according to the order of sequence of each user data package of transmitting on multicarrier; Separate formatting module 202, be used under the control of described control module, remove form control information in the user data package after resetting according to the order of sequence, and the user data transmission that will remove the form control information is to high-rise in high speed media access control sublayer.
Like this, transmitting terminal MAC-d transfer of data is behind the MAC-hs sublayer, under the control of control module 101, form set form packet (data format sees aftermentioned for details) through PDU formatting module 102 with certain-length, packet is assigned to different carrier waves by data distribution module 103.The packet of each carrier wave sends to physical layer through MC HARQ module 104 under the scheduling controlling of control module 101, each carrier wave sends by air interface after physical layer is finished relevant treatment.Receiving terminal is finished each carrier wave physical layer process, under the control of control module 201, finish packet HARQ reception control on the carrier wave by MC HARQ204, after the correct reception of data, submit to data confluence module 203 to finish the reorganization of the data of each carrier wave, at last remove form control information at the MAC-hs layer by separating formatting module 202, transfer of data is to high-rise.
Fig. 3 has described the data packet format schematic diagram that PDU formatting module 202 forms.Upper layer data is transferred to the MAC-hs sublayer with MAC-d PDU form, control module is according to the Radio Link situation of feeding back on each carrier wave, determine the size of the packet that each carrier wave need be dispatched, select suitable MAC-dPDU number, be the N among the MAC-hs Header, each MAC-d PDU of N be concatenated into add that together MAC-hs header forms the packet of set form.In HSDPA, the packet of this set form is MAC-hs PDU.Wherein MAC-hs header comprises: version flag VF (VersionFlag), queue number Queue ID (Queue Identification), order of transmission TSN (TransmissionSequence Number), and the size index of the protocol Data Unit that is connected in series later sign SID (SizeIndex Identifier), protocol Data Unit quantity N (Number of MAC-d PDU), flag bit F (Flag).Its concrete implication is not described in detail at this referring to the correlation technique standard.
Fig. 4 has provided the data distribution schematic diagram of multi-carrier HSDPA.It is the function of data distribution module 103 among Fig. 2.Control module 101 has known that this MAC-hsPDU user data transmits on that carrier wave when the MAC-hs PDU that forms, therefore just once give corresponding carrier wave with each allocation of packets in diverter module 103.As shown in the figure, all carrier waves obtain a MAC-hs PDU successively in a TTI.The packet of each carrier wave is sent to HARQ entity separately respectively under the control of control module 101, finish the transmission control of HARQ agreement.Because the parallel scheduling of a plurality of carrier waves, therefore a TTI exists a plurality of HARQ processes to dispatch simultaneously, so control module 101 need be finished parallel HARQ scheduling in the multi-carrier HSDPA.
Corresponding with transmitting terminal, Fig. 5 has described the function of data confluence module 203, and it mainly finishes the rearrangement according to the order of sequence of a plurality of carrier wave transmitting data bags of a user.Particularly, in each TTI, the a plurality of carrier wave parallel transmission packets of possibility, because the transmission characteristic on the different carrier is different, these data re-transmission situations are not quite similar, and some carrier wave may not need to retransmit, and some carrier wave may need once or repeatedly retransmit, even still can not correctly receive up to abandoning through repeatedly retransmitting, therefore the parallel data that sends in the same TTI wraps in receiving terminal and might not correctly receive in same TTI.In addition, data be submitted to high-rise need sequenced, so confluence module 203 need be finished data and recombinate according to the order of sequence, reassembly algorithm can the merchandiser carrier case under HSDPA identical.Specific algorithm does not repeat them here.
In addition, the invention allows for the configuration of the control channel of the data parallel dispatch that is applicable to multi-carrier HSDPA.It is a plurality of times/ascending control channel parallel transmission.Each following/ascending control channel carries the control information of a parallel transmission packet in a TTI, wherein the down control channel control information transmission is used for the packet reception, and ascending control channel is used for transmitting feedback information, and both are interrelated.
A plurality of following/up parallel control the channel that is disposed, physically can be evenly distributed in a plurality of carrier waves (be on each carrier wave each under one/ascending control channel), also can anisotropically be distributed in (being that some carrier wave can not distribute control channel) on each carrier wave, even all control channels all are distributed on the same carrier wave.But be mutually related down control channel and ascending control channel must transmit on same carrier wave.
Fig. 6 has described the data parallel dispatch entity in conjunction with the channel architecture of designed multi-carrier HSDPA.Merchandiser carrier HSDPA system is the same, and multi-carrier HSDPA comprises three kinds of channel: HS-SCCH, HS-DSCH and HS-SICH.Wherein dispose the channel of a cover HSDPA on each carrier wave independently, comprise HS-SCCH associated with each other, HS-DSCH and HS-SICH.HS-SCCH provides control information for the transmission of HS-DSCH, and HS-SICH provides feedback information to be used to indicate HS-DSCH transmission situation.(Fig. 6 is that example is illustrated with 3 carrier waves, and actual the use is not limited to 3 carrier waves).
Among Fig. 6, three carrier wave C1, C2 and C3 provide data transport service at the subframe N-1 of system, N and N+1 for user A, B and C respectively.Cross over a plurality of carrier transmission in N, N+1 subframe user A data.The N subframe, when A is respectively having on three carrier waves under the packet situation, its control channel HS-SCCH also respectively has a cover on three carrier waves, for the data HS-DSCH on each carrier wave provides control information.Equally, the N+1 data are transmitted on C1 and C2, and its corresponding control channel respectively has a cover on C1 and C2.The corresponding feedback channel of N sub-frame data transmission also comprises three covers, and a cover is respectively arranged on each carrier wave.The feedback channel of N+1 frame data correspondence is each cover on carrier wave C1 and C2.
As optional a kind of mode, when same user's data was transmitted on a plurality of carrier waves, a plurality of control channels physically can be at same carrier wave.For example, 3 among Fig. 6 cover HS-SCCH can be on any one of C1, C2 and C3 corresponding to the control information of N sub-frame data transmission.Similarly, also can on any one of C1, C2 and C3, transmit corresponding to N sub-frame data transmission feedback channel.
Though uplink/downlink control channel HS-SCCH and HS-SICH can be configured on the different carrier neatly, be mutually related HS-SCCH and HS-SICH must be at same carrier waves.
Fig. 7 has described the channel domain structure of HS-SCCH, comprising: transformat indication TRFI, HARQ process number HARQ Process, redundancy versions RV, new data packets are represented NDI, HCSN and UE ID.With respect to single carrier HSDPA system, wherein HARQ Process number because the parallel scheduling of multicarrier, is increased to 5 bits by 3 bits of original single carrier HSDPA system.TRFI also changes to some extent, need add the bit (Carrier Info) of indication carrier wave information therein.Fig. 3 has shown a possible HS-SCCH channel domain structure, and actual the realization is not limited thereto, but no matter adopts what HS-SCCH domain structure, should not influence the HSDPA channel architecture that relates in this patent.
Fig. 8 has described the domain structure of feedback channel HS-SICH, comprising: RTBS, RMF and ACK/NAK.The HS-SICH domain structure merchandiser carrier HSDPA system here identical.
