Description
Technical field
The present invention relates to a kind of radio block immediate processing method, refer in particular to a kind of radio block immediate processing method and system thereof that is used for employing bitmap (short bitmap) indication of transfer of data.
Background technology
Along with scientific and technological progress, people are also improving constantly the requirement of mobile communication business and quality, so demand that proposition seamlessly transits to the 3G (Third Generation) Moblie technology, major technique to the evolution of 3G has GPRS (General Packet Radio Service, use packet wireless business), EDGE (Enhanced Data ratesfor GSM Evolution, Enhanced Data rates for GSM Evolution), HSCSD (High Speech CircuitSwitched Data, and the emphasis of research concentrates on and utilizes limited frequency spectrum resources to improve transmission rate and reduce propagation delay time the high speed voice circuit switched data).
GPRS is the packet data exchanged technology of introducing in GSM (Global System for Mobile communications, global system for mobile communications) network.It is superimposed on the gsm system, has prolonged the useful life of GSM, and it is based on the forwarding of packet data package and the statistic multiplexing of channel, thereby the data service that existing GSM is provided has leaped more than the 100Kbps from 9.6Kbps first.Because GPRS still adopts the GMSK the same with GSM (Gaussian Minimum Shift Keying, Guassian Minimum Shift Keying GMSK) modulation system, transmission rate can't reach the 2Mbps of 3G business need, in order fully to satisfy the bandwidth demand that following radio multimedium is used, EDGE provides a transitional scheme from GPRS to the 3G (Third Generation) Moblie.It and UMTS (Universal Mobile Telecommunications System, universal mobile telecommunications system) shared core net, by introducing Iu interface, evolution GSM EDGE Radio Access Network GERAN (GSMEDGE Radio Acesss Network, GSM EDGE wireless access network).
EDGE is a kind of data enhancement mode mobile communication technology based on the GSM/GPRS network, is called the 2.75G technology by people again usually.This technology mainly is to use broadband service, can allow the network of use 800,900,1800,1900MHz frequency range that the partial function of 3G (Third Generation) Moblie network is provided, and its major technique has:
(1) 8PSK modulation realize 3 bit data of carrying on each modulation signal, and GMSK can only be carried the data of 1 bit under kindred circumstances, so maximum transmission rate reaches three times of GPRS.In mobile environment, can stablize and reach 384Kbps, in static situation even can reach the high speed of 2Mbps;
Modulate and coded system, i.e. MCS1～9 for (2) 9 kinds.Wherein MCS1～4 have kept the GMSK modulating mode, and the 8PSK modulation is adopted in MCS5～9, and different MCS have been defined different data block sizes and channel redundancy coding.
(3) link adaptation mechanism, promptly these nine kinds of coded systems of MCS1～9 are divided into 3 groups of (Family A (MCS-3, MCS-6, MCS-8, MCS-9), and Family B (MCS-2, MCS-5, MCS-7) and FamilyC (MCS-1, MCS-4)), in communication process, coded system can change on the same group.Select coded system according to carrier/interface ratio during data re-transmission, when guaranteeing speech quality, the use of maximum Radio Resource.
(4) steadily increase redundancy transmission means (Incremental redundancy) is in the GPRS transfer of data, if error code appears in data block, this data block will retransmit, and is correct until transmission.And in the EDGE technology, introduced the incremental redundancy mode, it is the combination of ARQ (Automatic Repeat request, repetitive requests automatically) and two kinds of technology of FEC.Data block adopts different Punching scheme when retransmitting, and the result in that receiving terminal will transmit at every turn effectively recombinates, and recovers legacy data, thereby has reduced the number of times that retransmits, and has improved the efficient of transmission.
(5) automatically to regulate the size of RLC window in the gprs system be that speed with the GPRS transmission is complementary and fixing to the size of RLC window.Because EDGE provides higher message transmission rate, need to increase the size of RLC window accordingly.Because EDGE has 9 kinds of different channel speeds, the size of RLC window need adapt to different coded systems, regulates automatically again.This characteristic has also improved the efficient of EDGE transfer of data.
In the wireless resource allocation mode, two kinds of different mechanism are used in uplink and downlink.Temporary Block Flow TBF (Temporary Block Flow) is interim connection between mobile station MS and the network N W, only just exists in the process of data forwarding.It is supported in the unidirectional forwarding of LLC (Logic Link Control, the logic link control) Packet Data Unit on the grouping physical channel.A TBF can go up at one or more PDCH (Packet Data Channel, Packet Data Channel) and use Radio Resource.Network has distributed Temporary Block Flow indication TFI (Temporary Flow Identify) for each TBF, and in the TBF of Chu Xianing, the TFI of each TBF is different at the same time.The time slot of distributing to GPRS is called PDCH, the PDCH that network uses for the MS assignment by control information.On the descending PDCH that distributes, MS is by detecting the ownership that TFI discerns this TBF.
In allocation of radio resources and the wireless transmission, the unit that radio block is basic, each radio block is made up of 4 burst.High-rise each LLC frame is made up of a series of RLC pieces, and the transmission of RLC piece is carried by radio block, and because of the difference of coded system, 1 radio block can carry 2 RLC pieces at most.
In the prior art, in order to optimize the transfer of data under the packet switched mode, RLC data block is transmitted in RLC (Radio Link Control, Radio Link control)/MAC (Media Access Control, the medium access control) is subjected to ARQ (Automatic Repeat reQuest under the affirmation mode, automatic repetitive requests) mechanism control is by the information of poll by the RLC data block of MS report related downlink situation and success reception.Polling mechanism is only applicable to downlink data transmission, issues polling request by packet control unit PCU (Packet ControlUnit) control.Transmitting terminal comes the addressing RLC data block with send window, and in send window, RLC data block is expressed as not transmission, wait acknowledge respectively, correctly receives and wrong accepting state.If a RLC piece was not sent out, then be identified as not transmit status,, this piece is designated the wait acknowledge state in case being sent out.Can know after the ACK/NACK information that receives downlink grouped whether the piece that sends is previously correctly received, and corresponding renewal send window.If data block is correctly received, then this piece is identified as correct accepting state (ACK); If receive wrong or lose, then this piece is identified as wrong accepting state (NACK); If do not receive response message, then keep the wait acknowledge state.After send window upgrades, can slide into the position of the data block of first dont answer.
The frequency of poll can be according to the adaptive adjustment of the situation of Radio Link, and when wrong piece rate BLER (BlockError Ratio) rising, poll frequency increases; Otherwise poll frequency reduces.Poll is also considered the scheduling frequency of RLC data block.Figure 1 shows that the hypothesis polling interval is the polling procedure of 12RLC Block under the ARQ mechanism.
Adopt above-mentioned polling technique, could organize to wrap and pass to high level because the rlc layer of MS need be collected whole RLC pieces that the LLC frame comprised.Network by poll after the ACK/NACK report of MS response can know just whether MS correctly receives all descending RLC pieces.Because of poll is to produce at interval, when lost block occurring or when wrong, the piece that network can not be known at once and retransmit wrong piece or lose just can retransmit after having only by the time poll and MS to report the ACK/NACK report.In actual conditions, PCU obtains descending wrong piece or loses the time of the about 150～250ms of report needs of piece, so just produces bigger transmission delay.
In order to solve the defective that exists in the technique scheme, adopt quick A ck/Nack mechanism replenishing as polling mechanism, quick A ck/Nack takies part upstream data space and transmits the Ack/Nack report, and only needs 1 short bitmap (bitmap) indication just can represent the reception condition of corresponding descending RLC block.Because of 1 radio block can carry 2 RLC block (MCS7-9) at most, so need corresponding 1 radio block among the short bitmap with 2bit.Be defined as follows:
The concrete implication of table 1 quick A ck/Nack short bitmap
| 00 | -build mistake-build is correct, but that TFI does not belong to current mobile station-build is correct, and TFI is also correct, but whole RLC data decode mistakes |
| 01 | Build is correct, and TFI is also correct, but the 1st RLC data decode mistake, the 2nd RLC data decode correct ( |
| 10 | Build is correct, and TFI is also correct, but the 1st RLC data decode is correct, the 2nd RLC data decode mistake ( |
| 11 | Build is correct, and TFI is also correct, and all the RLC data are all decoded correctly |
In transmission course, when having many TBF, that short bitmap represents is the RLCblock of all TBF, has the TFI value of appointment when what receive to descending RLC block, and the bit among the short bitmap will be set to 1.When the radio block that receives at moment Tx has polling request, the reception condition of radio block on the 1st descending time slot distributing constantly of the 1st couple of bit bit representation Tx among the short bitmap then, the reception condition of radio block is analogized so backward on the 2nd descending time slot that the 2nd couple of bit bit representation Tx distributes constantly.If also have remaining bit space among the short bitmap, following a pair of bit can represent the position reception condition of radio block on the 1st descending time slot that Tx-1 (being the moment before the 20ms) constantly distributes, analogizes so backward.
With reference to content shown in Figure 2, the operating process of quick A ck/Nack report has been described.The descending time slot that distributes for TBF1 among Fig. 2 is TS0,1,2,3, and Tx MS constantly receives polling request at time slot TS2, and MS sends data at corresponding ascending time slot TS2, and this moment, these data had the ack/nack report information, i.e. short bitmap.2bit (11) expression Tx that the 1st row circle 22 circles are lived constantly the radio block on the descending time slot TS0 correctly receive, the TFI that does not have self in the radio block on the 2nd couple of bit (00) the expression descending time slot TS1, radio block on the 3rd couple of bit (11) the expression descending time slot TS2 correctly receives, and the radio block on the 4th couple of bit (00) the expression descending time slot TS3 receives mistake.Correct in 2bit (10) expression Tx-1 that the 2nd row circle 21 circles the are lived data division decoding of the 1st RLC piece of the radio block carrying on (during preceding 20ms) descending time slot TS2 constantly, the data division decoding error of the 2nd RLC piece.
For the up RLC data block of EGPRS of band short bitmap information, the ES/P field in its block data structure is non-0, and the RS field is to adopt quick A ck/Nack mechanism at 1 o'clock; Non-0 when the ES/P field, and the RS field is to adopt conventional polling mechanism at 0 o'clock, and RRBP only represents the corresponding time of poll of 20ms and 40ms respectively with 1bit.Network side can dynamically be controlled two kinds of Ack/Nack mechanism like this, and the short bitmap in quick A ck/Nack is incorrect to be received, and available conventional poll is confirmed the RLC piece of losing affirmation.
In sum, part and parcel is the time delay compression in the GERAN evolution, and RTTI (Reduced TTI) technology is one of its implementation.Existing radio block is based on 4 burst, is mapped to 1 time slot on 4 continuous T DMA frames, and time span is 20ms, i.e. a TTI.The RTTI method has 2: 4-burst RTTI, divide two kinds of compression of RTTI time domain and frequency domain compressions again, RTTI time domain compressed capability level mainly contains 10ms and 5ms, original 20ms radio block will be mapped to 2 time slots on 2 continuous T DMA frames and 4 time slots on 1 tdma frame respectively, the compression of RTTI frequency domain, consider two situations of carrying, original 20ms radio block is mapped on 2 continuous T DMA frames of 2 carrier waves; The new radio block of 2-burst RTTI is made up of 2 burst (burst), is mapped to 1 time slot on 2 continuous T DMA frames.Fig. 3 represents radio block and the time slot corresponding relation of 4-burst RTTI in the 20ms cycle, and each square is represented a radio block; Solid box among Fig. 4 A is represented existing radio block, and the frame of broken lines among Fig. 4 B is represented the radio block of 2-burst RTTI, and each square is represented 1 burst.As seen, for the travelling carriage that uses the RTTI technology, the indicating means of short bitmap is no longer suitable in the quick A ck/Nack technology, therefore the indication that need stipulate short bitmap again.
