Description
Technical field
The present invention relates to network communications technology field, relate in particular to repeating method and system that a kind of high speed downlink packet inserts.
Background technology
High speed downlink packet inserts (HSDPA, High speed downlink packet access) be a kind of modulation and demodulation algorithm that 3GPP proposes in order to satisfy the asymmetric demand of up-downgoing data service in the R5 agreement, it can bring up to 10Mbps to downstream data traffic speed under the situation that does not change the WCDMA network configuration of having built.
This technology is a kind of important technology that the WCDMA networking later stage improves downlink capacity and data service rate, automatically retransmit (HARQ) by adaptive modulation and coding (AMC), mixing, and the series of key techniques such as fast dispatch of base station, realized descending high speed data transfer.In the WCDMA system, the introducing of HSDPA has increased by three kinds of channels, be respectively high-speed physical downlink shared channel (HS-PDSCH) (HS-PDSCH in downlink transmission data information, High Speed PhysicalDownlink Shared Channel), the High-Speed Shared Control Channel (HS-SCCH of transmission Downlink Control Information, High Speed Shared Control Channel) and the transmission uplink feedback information High-Speed Dedicated Physical Control Channel (HS-DPCCH, High Speed Dedicated ControlChannel).
Hybrid automatic re-transmission (HARQ, Hybrid Automatic Repeat Request) is a kind of error correcting technique.The meaning of mixing (Hybrid) is the characteristics that it combines forward error correction (FEC) and re-transmission (ARQ) dual mode.R99/R4 has adopted traditional ARQ method, and functions of retransmission realizes that in Radio Link control (RLC, Radio Link Control) HSDPA has increased the H-ARQ function at NodeB, in order to improve transmission rate and to reduce time delay.
What HSDPA adopted is the HARQ mechanism that multichannel stops grade, described stop-and-wait protocol (Stop﹠amp; Be meant that wait SAW) concerning each channel, channel is waited for and received correct affirmation information, obtains sending next packet again after the confirmation after sending data.This agreement is simple and easy to realize, but the utilance of channel is not high, and multichannel stops waiting and can solve the not high problem of utilance.Be illustrated in figure 1 as the schematic diagram that one two channel stops grade.
As shown in Figure 1, data channel is divided into odd number time slot and even number time slot, is used for discerning different ARQ protocol instances.State of parity is determined by control channel or is determined that by global system information the least significant bit of time slot counter (LSB, Least Significance Bit) can be discerned strange or even channel.Data block arrives from network and makes a start and sort, and makes a start and uses dual channel sorting unit to allow data block to enter strange still even transmitter, and each transmitter is realized conventional ARQ algorithm such as stop at strange or even time slot separately then.With make a start similarly, receiving end has also comprised strange and even receiver, each receiver is equipped with HARQ decoder separately.The HARQ decoder sends data block on feedback channel separately successfully still be failure signal, and strange and even feedback channel is all supported example such as stop separately, in like manner can release the multichannel situation.
For data retransmission, there are two classes to retransmit the merging mode, be called: catch up with merging (CC, Chase Combining) and incremental redundancy technology (IR, Incremental redundancy).
Chase Combining mode just resends Bit data one time on the basis that just passes, and is a kind of simple energy stack that just passes data; When IR Combining retransmits data are handled, can be regarded as the process of a coding.The re-transmission gain of IR Combining is higher than the part of ChaseCombining, is exactly the coding gain of this cataloged procedure.
The HARQ agreement is based on the mechanism of following line asynchronous and uplink synchronous.HARQ takes in row at the UE side joint and merges, and the size decision of UE side internal memory can be adopted which kind of form transmission data of which kind of mode.
In the HARQ agreement, the main feedback acknowledgment of up signaling/(ACK/NACK) unconfirmed; The signaling parameter of down control channel comprises HARQ process identification (PID), new data block indication.For HARQ, recipient and transmit leg are all followed same HARQ process, and each process has unique sign.The new data block indication is used for indicating that current data block is a new data block, is different from re-transmitting data block.Comprise indication information in the data packet head of MAC-hs (Mac-hs is the MAC entity of the processing HS-DSCH transmission channel that defines in 3GPP TS 25.321 agreements), relevant parameter has the priority classification indication to number with data block: priority classification is indicated and is used for distinguishing the different priority of logical channels that is mapped on the same transmission channel; Data block numbering is the sign new data block, is used for identification data block when ordering.
At UMTS Terrestrial radio access network network (UTRAN, UMTS Terrestrial RadioAccess Network, UMTS wherein, Universal Mobile TelecommunicationsSystem, be Universal Mobile Telecommunications System) side relevant with the HARQ agreement scheduling, HARQ entity and HARQ process arranged, its concrete function is as follows respectively:
The scheduling of UTRAN side is used for the data queue with certain attribute is handled.The different priorities that has according to the Frame Protocol content of Iub, the data queue of each priority all is furnished with the time delay property parameters that gets off from RNC, the obtained data-rate information that (NodeB) reports from the base station.Scheduling is dispatched all user terminals (UE) in the sub-district according to the sending order of above parameter decision new data block and re-transmitting data block.
The HARQ entity function of UTRAN side, is provided with the HARQ process identification (PID) at the numbering that is used to queue priority to be set, transmission data block is set.
The HARQ process of UTRAN side is used to determine the deletion (Xnd) of new data block indicated value to be provided with, and for the data of new transmission, the new data block indicated value adds 1, if promptly original value is 0, is 1 if become 1 original value so, becomes 0 so; For the data that retransmit, the new data block indicated value is constant.In addition, the HARQ process is handled up ACK/NACK, reports scheduler, the opportunity of scheduler decision retransmission data or transmission new data.
(r, s) control HARQ retransmits the strategy that merges to regulation, retransmits to merge in the UE side to obtain certain coding gain constantly by parameter among the prior art use agreement 3GPP TS25.212.
But prior art is not stipulated the scheduling strategy that retransmits the user, under multi-user's situation, when the dispatching priority that retransmits the user by other factor affecting such as CQI, when causing dispatching priority very low, this user that need retransmit can occur and always can not get the situation of dispatching, cause NodeB and UE side all can't discharge the re-transmission buffer memory.

Embodiment
Core of the present invention is in user's scheduling process, improves according to the user and attempts the weight that number of retransmissions carries out user's scheduling, reduces the weight of other user's scheduling; When described weight was higher than other the weight of user scheduling, just the number of times of attempting retransmitting according to the user was dispatched each user, and followed stop-and-wait protocol each user's data is sent to receiving terminal; Data retransmission obtains coding gain in receiving terminal and biography data merging just.
Say that more specifically what the present invention solved is the problem that user data retransmits in following the system of stop-and-wait protocol.
Because stop-and-wait protocol is followed in the user's data transmission, when a certain user's data takes defeat, need transmitting terminal to retransmit this user's data, otherwise according to stop-and-wait protocol, system will wait for this user's data, can't carry out follow-up workflow always.
Therefore, must as early as possible the user data that takes defeat be retransmitted to receiving terminal as early as possible.Owing to there are a plurality of users, this just need dispatch this user before transmission.
Have multiple scheduling scheme when the user is dispatched, the present invention selects the highest scheme of weight to dispatch by the adjustment to various scheduling scheme weights.
The scheduling scheme that influences user scheduling includes but not limited to: according to user channel quality indication (CQI) dispatch, period of reservation of number (Wait Time) is dispatched, dispatch and the user attempts number of retransmissions and dispatches according to the Mac_hs queue priority.
The present invention does following setting to various scheduling scheme weights:
The sum total of various machine-processed weights is 1, and when the user attempted the scheduling mechanism weight rising of number of retransmissions, the weight of other scheduling mechanisms reduced.
When through after repeatedly retransmitting, the weight of attempting the scheme that number of retransmissions dispatches according to the user can be higher than the weight of other scheduling schemes, how many dispatched users successively of at this moment attempting number of retransmissions according to the user during system call user are dispatched next user again after a user's data successfully transmits.
Below in conjunction with the specific embodiment of the invention accompanying drawing the present invention is elaborated.
Scheduling to HSDPA user, can set according to actual conditions and carry out with reference to some parameter, the parameter that these can reference includes but not limited to: user channel quality indication (CQI), period of reservation of number (Wait Time) and Mac_hs queue priority and user attempt number of retransmissions.
For the scheme that the indication according to user channel quality is dispatched, can be according to the height order dispatched users of actual conditions setting according to channel quality, for example, at first the high user of scheduling channel quality dispatches other users then from high to low;
For the scheme of dispatching according to period of reservation of number, can dispatch the user according to each user's stand-by period, for example, at first dispatch the longest user of stand-by period, according to stand-by period order dispatched users from high to low;
For the scheme of dispatching according to the Mac_hs queue priority, can dispatch at the height of Mac_hs formation medium priority according to each user, for example, the user that first dispatching priority is high dispatches other users then from high to low;
For attempt the scheme that number of retransmissions is dispatched according to the user, can dispatch according to the concrete condition that each user attempts retransmitting, for example, scheduling earlier attempts retransmitting maximum users, according to attempting number of retransmissions order from more to less, dispatch each user one by one.
The present invention need determine when dispatched users user's scheduling according to which kind of situation is carried out, and promptly determining to dispatch according to user's channel quality still is that the number of times of attempting retransmitting according to period of reservation of number, user Mac_hs queue priority or user is dispatched.
What solve among the present invention is to occur unusual and user data retransmit issue that cause when user's data at receiving terminal, and stop-and-wait protocol is followed in the user's data transmission.Therefore, when a certain user's data takes defeat, need transmitting terminal to retransmit this user's data, otherwise according to stop-and-wait protocol, system will wait for this user's data always, can't carry out follow-up workflow.
Like this, the present invention selects to attempt the number of retransmissions dispatched users according to the user in multiple scheduling mechanism listed above, when certain user's data occurs then dispatching this user once more within a short period of time unusually at receiving terminal, sends this user's data.
Figure 2 shows that the workflow diagram of the embodiment of the invention one.
As shown in Figure 2, workflow of the present invention mainly comprises:
Because the present invention need dispatch the user according to the number of times that the user attempts retransmitting, so user's channel quality, stand-by period and the priority in the Mac_hs formation become the disturbing factor of user's scheduling among the present invention.The present invention realizes that by the weight control to each user's scheduling scheme making system attempt number of retransmissions according to the user dispatches the user.
In embodiments of the present invention, the factor of judgment of HSDPA user's scheduling comprises: A, B, C and Trtrans, wherein A, B, C and Trtrans are the value after the quantification, A represents user's channel quality scheduling mechanism, B represents user's stand-by period scheduling mechanism, C represents user's Mac_hs queue priority scheduling mechanism, and Trtrans attempts the number of retransmissions scheduling mechanism for HSDPA user.
The present invention judges which kind of scheduling mechanism of use by the weight of A, B, C and Trtrans, selects the machine-processed dispatched users of weighted value maximum for use.
The weight of A, B, C and Trtrans is respectively Δ Ai, Δ Bi, Δ Ci, Δ Trtransi, i ∈ { 0, l}, l is a maximum retransmission, wherein i=0 represents just to pass, and l equals the i time re-transmission of other value representation, and having between Δ A-i, Δ Bi, Δ Ci, Δ Trtransi and being worth is 1 relation, be Δ Ai+ Δ Bi+ Δ Ci+ Δ Trtransi=1, the initial value of Δ Ai, Δ Bi, Δ Ci, Δ Trtrans is for being shared proportion in A, B, C and each comfortable number of retransmissions of Trtrans.
System adopts the highest mechanism of weight that the user is dispatched among the present invention, and the sum total of various machine-processed weights is 1, and when the user attempted the scheduling mechanism weight rising of number of retransmissions, the weight of other scheduling mechanisms reduced.
The physical relationship of various user's scheduling mechanisms was during user of the present invention retransmitted, and when the i secondary data sent, each weighted value satisfied:
ΔTrtrans?i＜ΔTrtrans(i+1) i∈{1，l}
ΔAi+1＜ΔAi i∈{1，l}
ΔBi+1＜ΔBi i∈{1，l}
ΔCi+1＜ΔCi i∈{1，l}
Promptly along with the shared weight of the increase number of retransmissions of number of retransmissions will constantly become big, other dispatching priority factors A, the shared weight of B, C is then corresponding reduces, the wherein increment of Δ Trtrans i and Δ Ai, Δ Bi, the reduction of Δ Ci can be according to scheduling needs flexible configuration.
For example, currently do not use the user who dispatches according to number of retransmissions for one, when this user of scheduling carries out transfer of data, when this user data transmission failure of certain reason, then the present invention will improve this user according to the weight of attempting the scheduling mechanism that number of retransmissions dispatches, for example, Δ Trtrans i can be after each data transmission fails 0.03 speed improve and retransmit proportion, and Δ Ai, Δ Bi, Δ Ci reduce by 0.01 respectively in each back weight that retransmits, and the weight raising amount of Δ Trtrans i is identical with the sum total of Δ Ai, Δ Bi, Δ Ci weight reduction amount.After through the failure of n data transfer, the weight of Δ Trtrans i has improved n * 0.03, the weight that has so just improved the scheduling mechanism of dispatching according to number of retransmissions shared proportion in various scheduling mechanisms.The numerical value of Δ Trtrans i raising here can be provided with adjustment, definitely is not 0.03, and the decline numerical value of Δ Ai, Δ Bi, Δ Ci also needn't be identical.
After the user attempts retransmitting once, its weight according to the scheduling mechanism that number of retransmissions is dispatched may be still very little, this system still uses another scheduling mechanism dispatched users, but under normal circumstances, under another kind of scheduling mechanism, this user still can be scheduled, when this user again by inferior re-transmission, be retransmitted the increase of number of times along with the user, this user improves once more according to the weight of the scheduling mechanism that the trial number of retransmissions is dispatched, and the weight of this scheduling mechanism shared proportion in various scheduling mechanisms further improves.
When the user repeatedly attempts transmission, then the user improves constantly according to the weight of attempting the scheduling mechanism that number of retransmissions dispatches, proportion also continues to increase, when this machine-processed weighted value reached predefined certain weighted value, system just adopted according to attempting the scheduling mechanism that number of retransmissions dispatches each user is dispatched.
After the system of selection of determining scheduling scheme, the selection scheduling scheme, dispatched users retransmits user's data, and its concrete grammar is as follows:
When Δ Trtransi reaches predefined weighted value, then use according to the scheduling mechanism of attempting how many dispatched users of number of retransmissions, be sent to receiving terminal with attempting the maximum user data of number of retransmissions.
When Δ Trtransi does not reach predefined weighted value, then use other user's scheduling mechanism scheduling and send the user, here the user who is dispatched therefore according to how many orderings of number of retransmissions, even certain user has attempted repeatedly retransmitting, but this user can't be by priority scheduling.
According to the stop-and-wait protocol that system uses, when receiving terminal does not receive required correct data, just wait for always that till receiving, so the transmitting terminal of system needs to receive correct data always according to certain user's scheduling mechanism dispatched users up to receiving terminal;
Under the effect of stop-and-wait protocol, the continuous dispatched users of transmitting terminal, Trtransi of every scheduling will increase, and other weights reduce, after repeatedly dispatching, the value proportion of Trtransi can progressively improve, when the Trtransi proportion reaches certain preset value, system begins to attempt according to the user the machine-processed dispatched users of number of retransmissions, and preferential the transmission attempted the many user's data of number of retransmissions.After each the re-transmission, the increasing degree of Trtransi can be set according to the concrete condition of current system, and the value of described predefined Trtransi proportion also is by setting according to actual conditions, helping applying in a flexible way of this method like this.
When the user attempts number of retransmissions and reaches the maximum that system allows, then abandon this user's corresponding HARQ process, carry out the transmission of new data.
After transmitting terminal sent to receiving terminal with data retransmission, the first biography data that receiving terminal is preserved the data retransmission received and receiving terminal originally merged, and by data retransmission with just pass the merging of data, obtained coding gain.
For receiving terminal, in order not take too much system resource, it can not indefinitely keep first biography data.Therefore, for the storage setting of receiving terminal abandons the time (Discard Times),, then abandon this HARQ data when data retention time surpasses when abandoning the time.When receiving terminal abandons the HARQ data, can not notify transmitting terminal.
