Description
Affiliated technical field
The present invention relates to the block data communication in CDMA (code division multiple access) cellular system, in especially mixed automatic retransmission request (HARQ, the Hybrid Automatic Repeat reQuest) system, send technology with receiving block data.
Background technology
In CDMA Cellular System, a plurality of users share identical frequency band and time slot, and the frequency expansion sequence that passes through to distribute is that channel code (address code) realizes multicast.The interference to receiver user that exist in the system this moment generally includes following a few part: other user sends the neighbor cell interference that multiple access disturbs and inter-cell user causes that causes in the self-interference that interchannel noise, subscriber signal Multipath Transmission cause, the residential quarter.In addition, under wireless propagation environment, the received signal quality of travelling carriage also depends on the factors such as distance, path loss, lognormal decline and RAYLEIGH short term rapid fading between base station and travelling carriage.The decline of signal under the impact of various interference and the wireless channel is so that reliable packet data transmission is subjected to very big impact in the CDMA Cellular System.As the basic fundamental that ensures the grouped data reliable transmission, HARQ can effectively correct and recover transmission of packet data mistake under jamming pattern and fading environment.
HARQ comprises forward error correction (FEC, Forward Error Correction) technology and automatic re-send request may (ARQ, Automatic Repeat reQuest) technology two big classes.FEC can effectively protect the transmitting of grouped data within the specific limits by add necessary error correction redundant information in grouped data waiting for transmission.Make mistakes when exceeding the error correction coding protection range in grouped data, simple FEC technology can't guarantee reliable packet data transmission.ARQ deals with the grouped data reception by re-transmission and makes mistakes.HARQ organically combines FEC and ARQ: at first, FEC manages to correct the common mistake of grouped data in transmission course; If when FEC can not correct whole wrong that grouped data occurs in transmission course, then retransmit coding groups by receiving terminal request transmitting terminal.HARQ can significantly improve the packet data transmission reliability owing to had error correction simultaneously and made mistakes retransmission mechanism, and can retransmit the dynamic change of adaptive channel and interference by makeing mistakes.
Because wireless communications environment is usually comparatively abominable, when channel fading and disturbance regime deterioration, for same grouped data, repeatedly retransmitting may appear in HARQ.Too much repeatedly re-transmission can increase transmission delay on the one hand, causes on the other hand the transmission blocking of grouped data at transmitting terminal, has a strong impact on the transmission performance of HARQ system.In existing HARQ system, generally take following methods to improve systematic function:
A, the FEC coding and decoding scheme of selecting to have strong error correcting capability are improved the HARQ systematic function.
FEC coding and decoding scheme with strong error correcting capability is applicable to that channel fading seriously reaches the reliable data communication of disturbing in the abominable situation; But when channel fading and disturbance regime improve, has the valid data transmission that too much error correction redundancy in the FEC coding and decoding scheme of strong error correcting capability is unfavorable for increasing the HARQ system.
B, in conjunction with a code folding, according to the situation of change of channel fading and disturbance regime, makeing mistakes by adjustment retransmits the coding groups form and improves the HARQ systematic function.
According to different channel fadings and disturbance regime, the HARQ system can be by the choose reasonable re-transmission coding groups of makeing mistakes, take full advantage of make mistakes retransmission mechanism and code folding, between the transmission reliability of grouped data and efficiency of transmission, obtain reasonably compromise, that is: the repetition transmission times of grouped data in minimizing channel fading and the disturb worsens situation increases channel fading and disturbs the valid data when improving to transmit.
China's CN01134954 patent application (" in ARQ system, using the blind type link adaptation method of confirming ", Korea S LG Electronics Inc., on June 19th, 2002; ) waiting link adaptation techniques and ARQ system to combine variable many yards transmission: system is according to the affirmative acknowledgement (ACK of receiving terminal feedback, ACKnowledgment) or negative response (NAK, Negative AcKnowledgment) variation of many yards transmission numbers with the adaptive channel condition dynamically adjusted in variation.This patent adopts the purpose of many yards technology, is not the parallel transmission for a plurality of coding groups that corresponding same grouped data is provided, and aims to provide the packet data transmission of variable-data-rate that what namely multi-code transmission was corresponding is many parts of different grouped datas.Europe EP1211840 patent application (Hybrid ARQ with parallel packet transmission, " has the mixed automatic retransmission request that parallel grouping sends ", U.S. Lucent Technologies, on June 5th, 2002) " parallel grouping sends " that proposes, its at be that different coding grouping sends from different time slots in " multichannel stops waiting the ARQ agreement "; In some assigned timeslots, transmitting terminal will only send a coding groups.
In a word, in the sending and receiving processing scheme of existing HARQ, transmitting terminal once only sends a coding groups corresponding to grouped data, or only retransmits a coding groups when makeing mistakes; Receiving terminal can only receive a coding groups corresponding to a grouped data when each the reception, what namely existing HARQ system adopted is the treatment mechanism of serial transmission and serial received.No matter select " having the FEC coding and decoding scheme of strong error correcting capability ", or " in conjunction with the sign indicating number folding; according to the situation of change of channel fading and disturbance regime; adjusting makes mistakes retransmits the coding groups form ", the HARQ systematic function still is subject to serial transmission and serial received treatment mechanism, there are many defectives: one, when channel fading aggravation and disturb worsens, for guaranteeing the transmission of packet data reliability, too much re-transmission repeatedly may appear, and then cause transmitting terminal the grouped data obstruction to occur, reduce the data transmission efficiency of system.Its two, limited code and merged improvement to the HARQ systematic function.No matter code merges is adopted any way of realization---and the cumulative merging of channel code-word symbol and channel code word combination merge, and it is that receiving terminal must have enough redundancies to the improved prerequisite of HARQ systematic function; And the serial (single part) of existing HARQ sends and serial (single part) reception programme can only be utilized time diversity---obtain enough redundancies by the follow-up re-transmission that makes mistakes.They are three years old, can not make full use of the parallel transmission and the parallel receive ability of the many parts of coding groups that prior art provided in the CDMA Cellular System, as interweave and many yards technology and V-BLAST (Vertical Bell labs Layered Space-Timewireless architecture) code diversity and space diversity that transmit diversity techniques provided, with further improvement HARQ systematic function.
The purpose of this invention is to provide a kind of parallel redundancy transmission and the parallel method that receives grouped data that merges in the HARQ system.This method is effectively being utilized on the telecommunication system resources basis, by improving the packet data transmission reliability, reduces the probability that HARQ system transmitting terminal grouped data is blocked and system's appearance retransmits repeatedly, improves the efficiency of transmission of grouped data, improves the HARQ systematic function.
Summary of the invention
The present invention solves its technical problem, and the technical scheme that is adopted is:
A kind of error detection coding by transmitting terminal, Error Correction of Coding, transmission, the reception of receiving terminal, error-correcting decoding, error checking and correction, and receiving terminal feeds back to check information, and parallel redundancy sends and the parallel method that receives grouped data that merges in the HARQ system that the step such as transmitting terminal forms, its characteristics are: the parallel redundancy that is sent as of transmitting terminal sends: the chnnel coding grouping after the Error Correction of Coding, after the perforation of N (N＞1) individual puncture module is processed, generate N perforation coding groups, carrying out number is the parallel transmission of N again; The parallel merging that be received as of receiving terminal receives:, separate perforation and process after N perforation coding groups at parallel receive, namely by N depuncture module, recover N and separate the perforation coding groups; Then, actuating code merge to be processed, namely to each other redundant N separate the perforation coding groups, carry out that code-word symbol is cumulative to be merged and/or code word combination merges, recover and merge chnnel coding and divide into groups, and send error-correcting decoding.
The invention has the beneficial effects as follows: transmitting terminal has been realized the parallel transmission of many parts of perforation coding groups of same grouped data when sending at every turn and makeing mistakes re-transmission; After receiving terminal adopts many parts of perforation of corresponding technology parallel receive coding groups, merge processing by sign indicating number, make full use of the parallel redundant information that sends, effectively utilizing on the telecommunication system resources basis, by improving the packet data transmission reliability, reduce the probability that HARQ system transmitting terminal grouped data is blocked and system's appearance retransmits repeatedly, improve transmission efficiency of packet data, improve the HARQ systematic function.
Above-mentioned parallel transmission and parallel receive adopt and interweave and many yards technology:
Transmitting terminal: the parallel number N that sends equals the orthogonal channel number of codes that the CDMA packet data communication system distributes; By N-1 interleaving block, the decorrelation that interweaves is processed to N perforation coding groups; Re-use N the orthogonal channel code that communication system is distributed, N perforation of parallel transmission coding groups;
Receiving terminal: after N coupling receiver module parallel receive data,, from the parallel receive data of N orthogonal channel, recover N perforation coding groups with (N-1) individual de-interleaving block.
When employing interweaves with the many yards parallel transmissions of technology realization and parallel receive, transmitting terminal uses (N-1) individual interleaving block, the decorrelation that interweaves is processed to the parallel perforation coding groups that sends of N, receiving terminal uses (N-1) individual de-interleaving block, to the coding groups deinterleaving of N parallel receive process to recover N receive the perforation coding groups after, N receives channel fading that the perforation coding groups experiences and interchannel noise close to mutually uncorrelated, merges a performance thereby be conducive to improve code.
Above-mentioned parallel transmission and parallel receive also can adopt the V-BLAST transmit diversity techniques:
Transmitting terminal: the parallel number N that sends equals the transmitting terminal number of transmit antennas; After using the orthogonal channel code spread spectrum of CDMA packet data communication system distribution, from N perforation of the parallel transmission of N transmitting antenna coding groups;
Receiving terminal: use the coupling receiver module, from the reception antenna parallel receive to data, by the V-BLAST signal processing module, recover N the coding groups of boring a hole.
In having disposed the V-BLAST transmit diversity systems of a plurality of emissions, reception antenna, because a plurality of antennas are separated enough far, channel fading and interchannel noise are separate to the impact of parallel N the perforation coding groups that sends, and this character will be conducive to improve code and merge performance.
The hole pattern of an above-mentioned N puncture module and N depuncture module can be accepted the adjustment of packet data communication system adaptively, when grouped data is made mistakes the rising of re-transmission frequency or decline, and the redundancy in corresponding increase or the minimizing perforation coding groups.
The strategy of this dynamic adjustment hole pattern, can be when the channel fading aggravation worsens with disturbance regime, it is more redundant that N the perforation coding groups that generates behind the follow-up coded packet data had, and to reduce the probability that the HARQ system makes mistakes and retransmits, improves the packet data transmission performance; Otherwise the redundant information of N coding groups of minimizing increases efficient packet data transmission to make full use of the wireless channel capacity.The dynamic adjustment of hole pattern can effectively take into account efficiency of transmission and the transmission reliability of grouped data in the HARQ system.
Above-mentioned sign indicating number merges to be handled, promptly separate the perforation coding groups to redundant each other N, carrying out code-word symbol adds up and merges and/or concrete grammar that code word combination merges is, to the merging that adds up of repeating data actuating code word symbol, merge and non-repeating data is carried out code word combination, error-correcting decoding and error checking and correction are sent in the merging chnnel coding grouping of generation.
Through interweaving and many yards technology or V-BLAST transmit diversity techniques are parallel sends and parallel receive N perforation coding groups, and through N depuncture module, the N that recovers solution channel fading and interchannel noise that coding groups experiences of boring a hole is mutually incoherent.Theory analysis and correlative study show that in this case, the cumulative merging of channel code-word symbol can effectively improve the effective signal interference ratio that merges code-word symbol in the chnnel coding grouping; The channel code word combination merges can effectively improve the error-correcting performance that merges the chnnel coding grouping.Therefore, parallel receive to N separate the perforation coding groups through code merge process after, will significantly improve the transmission reliability of grouped data, and then reduce the transmitting terminal grouped data and block, and the repeatedly sending probability that causes because reception makes mistakes of grouped data.
