Description

The TD-SCDMA system multi-carrier high-speed downstream grouping inserts implementation method
Technical field
The present invention relates to field of mobile communication, particularly (Time DivisionSynchronization Code Division Multiple Access, TD-SCDMA) in the system, a kind of multi carrier wave high-speed downlink grouping inserts implementation method to TD SDMA.
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.
The AMC technology is determined current channel capacity according to the situation (channel condition information CSI) of channel, determines suitable code modulation mode etc. according to capacity, so that send information to greatest extent, realizes than higher speed; And at each user's variations, but AMC can both provide the Modulation and Coding Scheme of respective change, thereby has improved the transmission rate and the availability of frequency spectrum.
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.After the receiving terminal reception information, if error situation in error correcting capability, then carries out error correction automatically, if exceeded the error correcting capability of error correcting code, but can detect, then receiving terminal feeds back to the corresponding signal of transmitting terminal, requires transmitting terminal to retransmit.
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 is carried out N-Channel SAW (See And Wait) Protocol (N channel stop-and-wait protocol), and 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 processID (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.
According to present 3GPP agreement, in the TD-SCDMA system, sub-district and carrier frequency are corresponding one by one.The channel resource configuration method that HSDPA in the single-carrier cell is relevant is: 1 HS-DSCH, many HS-SCCH are with every HS-SCCH HS-SICH one to one.When network side is UE configuration HS-DSCH resource, dispose 1～4 HS-SCCH, constitutes 1 HS-SCCH collection, dispose simultaneously and every HS-SCCH HS-SICH one to one.In carrying out the HS-DSCH data transmission procedure, each HS-DSCH TTI, Node B sends the relevant control channel of HS-DSCH at a HS-SCCH channel, and UE obtains these information by reading this channel, and sends feedback information on a HS-SICH channel corresponding with this HS-SCCH.In Node B side, each HS-DSCHTTI at certain UE, selects a HS-SCCH to use to UE by MAC-hs, promptly sends the relevant control channel of HS-DSCH to this UE on this HS-SCCH channel.In the UE side, if having a HS-SCCH to distribute to UE, do not use by its HS-SCCH collection, this HS-SCCH collection of UE continuous monitoring then, compare by the sign that reads " UE sign " information and UE self on the HS-SCCH, therefrom search for that HS-SCCH that is given this UE by actual allocated, up to the HS-SCCH channel that finds to distribute this UE, next TTI begins, only monitor and receive this HS-SCCH, use the control information of its carrying to receive the HS-DSCH data, and on a HS-SICH channel of this HS-SCCH correspondence, send feedback information, up at certain TTI, UE can not read the UE sign that conforms to oneself at this HS-SCCH, maybe can not read this HS-SCCH, then UE monitors the HS-SCCH collection that is assigned with again, is worth finding a HS-SCCH who distributes to this UE.
Foregoing description is about the HSPDA of TD-SCDMA system technology in the present 3GPP agreement.Yet, TD-SCDMA system in the 3GPP agreement is a single-carrier system at present, i.e. corresponding carrier frequency in sub-district, the spectrum width of single carrier frequency is 1.6M, because TD-SCDMA adopts the TDD mode of relative arrowband, theoretical peak speed on the single carrier wave can reach 2.8Mbps, and available descending peak rate is on the low side on the single carrier wave, can not satisfy the demand of operator to the high-speed packet data service in future well.Therefore, need be that some technological improvements are carried out on the basis with single-carrier cell HSDPA technology, to satisfy operator's demand higher to high-speed packet data service.
