Abstract

A method and system for implementing hybrid automatic repeat request (H-ARQ)-assisted automatic repeat request (ARQ) in a wireless communication system are disclosed. When an H-ARQ negative acknowledgement (NACK)-to-positive acknowledgement (ACK) error occurs, the H-ARQ receiver sends an H-ARQ NACK-to-ACK error indicator to the H-ARQ transmitter unless a maximum retransmission limit has reached, a maximum time for delivery has expired or a lifespan of the failed packet has expired. The H-ARQ transmitter sends a local NACK to the ARQ transmitter so that the failed packet is recovered at an ARQ level. The H-ARQ receiver sends a local NACK to the ARQ receiver if the H-ARQ receiver does not receive the failed packet before certain conditions occur. The ARQ receiver may send a status report to the ARQ transmitter for recovery of the failed packet.

Description

Be used to implement by the method and system of the auxiliary ARQ of H-ARQ
The application is to be on December 27th, 2006 applying date, and application number is 200680049848.7 divides an application.
Technical field
The present invention relates to wireless communication system.Especially, the present invention relates to a kind of method and system that is used for implementing the auxiliary automatic repetitive requests (ARQ) of mixed automatic repeat request (H-ARQ) at wireless communication system.
Background technology
In the conventional wireless communication system as Wideband Code Division Multiple Access (WCDMA) (WCDMA) the 5/6th edition and so on, high speed data transfer inserts (HSDPA) by high-speed downlink packet and High Speed Uplink Packet inserts the realization of (HSUPA) technology.In order to improve reliability of data transmission, H-ARQ and ARQ have wherein been implemented.
What Fig. 1 showed is conventional wireless communication system 100.System 100 comprises subscriber equipment (UE) 110, Node-B120 and radio network controller (RNC) 130.The H-ARQ entity is positioned at medium access control (MAC) layer 112 of UE 110 and the MAC layer 122 of Node-B 120.Grouping is designated transmission sequence number (TSN) in the H-ARQ transmitter then.The H-ARQ receiver receives grouping and attempts the grouping of this transmission of decoding.If can't decoded packet, that one H-ARQ receiver can be to H-ARQ transmitter loopback negative response (NACK), so that retransmit the grouping of described failure.If be correctly decoded grouping, that one H-ARQ receiver can send affirmative acknowledgement (ACK) to the H-ARQ transmitter for this grouping.When receiving NACK, to greatest extent predetermined if the number of retransmissions of failed packet is lower than, and the permission transmission time of failed packet do not expire as yet, that the one H-ARQ transmitter will retransmit this grouping.Otherwise this failed packet will be dropped and at the ARQ level restoration.
The ARQ entity is positioned at Radio Link control (RLC) layer 114 of UE 110 and the rlc layer 132 of RNC 130.Described ARQ entity is handled the re-transmission of failed packet.The grouping that this ARQ entity recovers those to be lost because the NACK of H-ARQ level is wrong to the ACK erroneous judgement.In rlc layer, it is very complicated that ARQ handles, and it has the option of a lot of running status reports.
When H-ARQ and the coexistence of ARQ function, for example in Universal Mobile Telecommunications System (UMTS) Node-B or the evolved Node-B of Long Term Evolution (LTE) (eNode-B), at this moment can consider auxiliary ARQ operation by H-ARQ.
What Fig. 2 showed is the example by the auxiliary ARQ operation of H-ARQ that proposes for third generation partner program (3GPP) standard.Transmitter 250 comprises ARQ transmitter 252 and H-ARQ transmitter 254.Receiver 260 comprises ARQ receiver 262 and H-ARQ receiver 264.H-ARQ transmitter 254 provides local ACK or local NACK for ARQ transmitter 252.
As shown in Figure 2, local NACK is that (for example because the maximum retransmit restriction) produces when H-ARQ transmitter 254 can't be finished the H-ARQ transmission.ARQ transmitter 252 sends ARQ protocol Data Unit (PDU) x (step 202) to H-ARQ transmitter 254.254 in H-ARQ transmitter sends to H-ARQ receiver 264 (step 204) with this ARQ PDU x.Described ARQ PDU x can't decode, and H-ARQ receiver 264 can send NACK (step 206) to H-ARQ transmitter 254.H-ARQ transmitter 254 then retransmits this ARQ PDU x (step 208) to H-ARQ receiver 264.Yet described ARQ PDU x still can't decode, and H-ARQ receiver 264 can send another NACK (step 210) to H-ARQ transmitter 254.At this moment, the number of retransmissions of ARQ PDU x is determined and reaches maximum retransmission limit (step 212).So H-ARQ transmitter 254 can be to the local NACK (step 214) of ARQ transmitter 252 transmissions about ARQ PDU x.
In addition, local NACK also can produce when H-ARQ transmitter 254 is reported NACK to the ACK mistake at H-ARQ receiver 264.Still with reference to figure 2, ARQ transmitter 252 sends ARQ PDU y (step 216) to H-ARQ transmitter 254.254 in H-ARQ transmitter sends to H-ARQ receiver 264 (step 218) with this ARQ PDU y.ARQ PDU y can't decode, and H-ARQ receiver 264 can send NACK (step 220) to H-ARQ transmitter 254.But for being ACK, and H-ARQ transmitter 254 is considered as ARQ PDU y successfully to transmit NACK by H-ARQ transmitter 254 erroneous judgement.264 of H-ARQ receivers detect NACK to ACK mistake (for example waiting for when PDU ARQ y retransmits via identical H-ARQ at H-ARQ receiver 264 and handling when receiving new PDU) (step 222).Described H-ARQ receiver 264 can send NACK to NACK error indicator (step 224) to H-ARQ transmitter 254.In case receive the NACK-ACK error indicator, that the one H-ARQ transmitter 254 can send local NACK to ARQ transmitter 252, and ARQ PDU y can be in ARQ level be restored (step 226).
Produce when as shown in Figure 2, local ACK is the above-mentioned two kinds of incidents that do not take place at interval at the fixed time about the ARQ grouping.ARQ transmitter 252 sends ARQ PDU z (step 228) to H-ARQ transmitter 254.254 in H-ARQ transmitter is sent to H-ARQ receiver 364 (step 230) with this ARQ PDU z.Described ARQ PDU z successfully decodes, and H-ARQ receiver 264 can send to ARQ receiver 262 (step 232) with this ARQ PDU z, and sends ACK (step 234) to H-ARQ transmitter 254.When not reporting NACK to the ACK mistake in definite interval at the fixed time (step 236), H-ARQ transmitter 254 can send local ACK (step 238) to ARQ transmitter 252.After the local ACK that receives from H-ARQ transmitter 254, ARQ transmitter 252 can abandon this grouping from the emission buffer.
In the above-mentioned example of the ARQ system auxiliary, wherein be to be that the unique important source of omission packet loss removes the complicated second layer (L2) status report mechanism by NACK is become the ACK false supposition by H-ARQ.If cause NACK that the ACK error indicator is lost because of discontinuous transmission (DTX)/ACK mistake or shared channel is lost, that one ARQ transmitter can't recover grouping.Thus, harmless transmission can't guarantee.
Current down link H-ARQ (the 5th edition) does not stipulate the maximum retransmission of grouping.Therefore, H-ARQ transmitter or receiver and do not know the maximum retransmission of each grouping.Suppose that ARQ transmitter and H-ARQ transmitter have identical PDU size.The H-ARQ launching opportunity is informed the H-ARQ receiver with missing segments (being not ARQ PDU).If retransmit ARQ PDU, that one H-ARQ transmitter will retransmit whole group and be not only missing segments.In addition, lost packets how to recover H-ARQ transmission also is unclear.
Summary of the invention
The present invention relates to a kind ofly in wireless communication system, be used to implement by the method and system of the auxiliary ARQ of H-ARQ.The H-ARQ receiver determines whether to have occurred H-ARQ NACK to the ACK mistake.When H-ARQ NACK occurring to the ACK mistake, unless the number of retransmissions of failed packet reaches the maximum delivered time of maximum retransmission limit, failed packet and expires and/or the failed packet expiration of time limit, otherwise the H-ARQ receiver can send the H-ARQ error indicator to the H-ARQ transmitter.The H-ARQ transmitter then can attempt recovering failed packet.If reach maximum retransmission limit, the maximum delivered time expires or the failed packet expiration of time limit, that one H-ARQ launching opportunity sends local NACK to the ARQ transmitter, so that in ARQ level restoration failed packet.If the H-ARQ receiver did not receive failed packet before certain condition occurring, that one H-ARQ receiver can send local NACK to the ARQ receiver.Based on the reception of described local NACK, the ARQ receiver can be to ARQ transmitter status report, so that recover failed packet.

Fig. 3 is according to the signaling diagram of enforcement of the present invention by the processing of the auxiliary ARQ operation of H-ARQ.
Embodiment
Feature of the present invention both can have been introduced integrated circuit (IC), also can be configured in the circuit that comprises a large amount of interconnecting assemblies.
Fig. 3 implements in wireless communication system 300 by the signaling diagram of the processing 400 of the auxiliary ARQ operation of H-ARQ according to of the present invention.System 300 comprises transmitter 310 and receiver 320.Transmitter 310 comprises ARQ transmitter 312 and H-ARQ transmitter 314.320 of receivers comprise ARQ receiver 322 and H-ARQ receiver 324.
ARQ in order to support to assist by H-ARQ according to of the present invention has defined following parameters here:
T Errorindicator: H-ARQ mistake indication timer is defined as the H-ARQ receiver at the time quantum that sends the failed packet re-transmission that should wait for before the HARQ error indicator.For making whole system easy to implement, comparatively preferably keep H-ARQ mistake indication timer constant.But H-ARQ mistake indication timer also can be adjusted based on service quality (9oS) demand.For example, the length of H-ARQ mistake indication timer can interrelate with dispatching priority.
N Retransmission: the maximum retransmission that is allowed for dividing into groups.Described maximum retransmission can be based on the QoS demand, and can dispose according to each COS.
T Delivery: after transmission first, be successfully to transmit the maximum delivered time that grouping is allowed.This maximum delivered time can be based on QoS demand (for example BLER (block error rate), stand-by period or the like), and can dispose according to each COS.
T RecoverySync: concerning synchronous H-ARQ, this parameter be the H-ARQ receiver after having transmitted the H-ARQ error indicator, expect take defeat the grouping time range.
T RecoveryAsync: concerning asynchronous H-ARQ, this parameter be the H-ARQ receiver after having transmitted the ARQ error indicator, expect take defeat the grouping time range.This timer can be associated with the QoS demand, and can dispose according to each COS.For example, the length of this timer can interrelate with dispatching priority.
W HARQ: the window (number of packet just) that should receive failed packet.If at W HARQWith the interior failed packet that do not receive, then suppose this packet loss.
In addition, can also provide the parameter about the grouping time limit (just transmitting the maximum time of grouping) for transmitter 310 and receiver 320 here.This parameter can offer H-ARQ receiver 324 and H-ARQ transmitter 314 by Centroid.If these parameters are according to each COS definition, that youngest can offer these parameters H-ARQ receiver 324 and H-ARQ transmitter 314 at first in service.
The maximum retransmission of grouping and/or time limit are dynamically to change according to the QoS demand.Described maximum retransmission both can be indicated by clearly identify the number of transmissions in the signaling that is associated, and also can indicate by the MAC stream that sign is associated with the maximum transmission times that is disposed.According to first kind of selection, the number of retransmissions of each grouping is to indicate in the control signaling that is associated that is used for transmitting first.According to second kind of selection, each MAC stream can be associated with certain number of retransmissions, in addition, by at the control signaling that the is associated sign MAC stream that is used for transmitting first, can be indicated maximum transmission times.If what use is second kind of selection, that one MAC stream that is identified will be converted into the maximum transmission times by the receiver configuration.In addition, if specific H-ARQ is handled certain the MAC stream that is exclusively used in one group of MAC stream, that youngest also can handle ID via H-ARQ knows maximum retransmission.As selection, in the signaling that is associated, can also be provided for indicating the mark of last transmission.
Will be described with reference to Figure 3 hereinafter according to of the present invention by the auxiliary ARQ operational processes 400 of H-ARQ.H-ARQ transmitter 314 sends grouping (step 402) to H-ARQ receiver 324.If successfully receive this grouping, that one H-ARQ receiver 324 can send to this grouping ARQ receiver 322 (not showing) in Fig. 3.If successfully do not receive this grouping, that one H-ARQ receiver 324 can send NACK (step 404) to H-ARQ transmitter 314.When sent NACK in step 404 after, H-ARQ receiver 324 will determine whether to have taken place H-ARQ NACK to ACK mistake (step 406).In case detect H-ARQ NACK to the ACK mistake, that one H-ARQ receiver 324 will produce H-ARQ NACK to the ACK error indicator, and sends it to H-ARQ transmitter 314 (step 408).
Concerning synchronous H-ARQ transmission, the H-ARQ re-transmission time is for known to the receiver.If H-ARQ receiver 324 receives new grouping when expection retransmits failed packet, unless failed packet has been transmitted maximum retransmission, otherwise H-ARQ receiver 324 will determine to have taken place H-ARQ NACK to the ACK mistake, and will send H-ARQ NACK to the ACK error indicator.
Concerning asynchronous H-ARQ transmission, when not reaching maximum retransmission, on H-ARQ receiver 324, timer T will be set Errorindicator, and H-ARQ receiver 324 can send NACK to H-ARQ transmitter 314 in step 404.If at timer T ErrorindicatorSuccessfully received failed packet at the expiration, that one timer T ErrorindicatorWill be reset to zero, and can not produce H-ARQ NACK the ACK error indicator.If H-ARQ receiver 324 is at timer T ErrorindicatorSuccessfully do not receive failed packet at the expiration, unless the number of transmissions of that one failed packet has reached maximum retransmit restriction, grouping maximum delivered time (T Delivery) expire and/or the failed packet expiration of time limit, otherwise H-ARQ receiver 324 will determine to have taken place H-ARQ NACK to the ACK mistake, and can send H-ARQ NACK to the ACK error indicator to H-ARQ transmitter 314.
H-ARQ NACK sends to H-ARQ transmitter 314 to the ACK error indicator from H-ARQ receiver 324, its announcement be that NACK on H-ARQ transmitter 314 judges by accident ACK.H-ARQ NACK handles with specific H-ARQ the ACK error indicator and the specific cluster of H-ARQ in handling is associated.The TSN that described H-ARQ NACK has comprised H-ARQ manipulation designator (ID) to the ACK error indicator and has been used for identifying the packet ID of H-ARQ processing.
Concerning synchronous ARQ, owing to can use failed transmission and the set time between the error reporting to get in touch H-ARQ NACK is associated with H-ARQ processing ID and grouping TSN to the ACK error indicator, so H-ARQ handles ID and TSN can remove.For instance, if exist four (4) synchronously H-ARQ handle, that one can send H-ARQ NACK to the ACK error indicator to the ACK mistake and after receiving the time t of grouping that TSN is n in that NACK takes place.
H-ARQ NACK can be independent of the H-ARQ operation to the ACK error indicator.This is to realize by the manipulation designator (if necessary) and the time migration of transmission in order to the time of reception of the mistake of sign reception.As selection, H-ARQ NACK can be used as physical layer signal to the ACK error indicator and transmission in the set time skew after having received the erroneous packet that receives.
If can send more than one grouping simultaneously to receiver 320 from transmitter 310, those one these groupings will have the Cyclic Redundancy Check of oneself, and the NACK that can use a H-ARQ NACK ACK error indicator to be sent a plurality of groupings indicates the ACK mistake.Thus, H-ARQ NACK can comprise that to the ACK error indicator a plurality of H-ARQ handle ID, associated packet TSN and/or timing slip.
H-ARQ NACK can also have the CRC of oneself to the ACK error indicator, so that guarantee reliable transmission.Having allowed that like this MAC or rlc layer signaling are used for H-ARQ NACK indicates the ACK mistake.Described H-ARQ NACK both can create in the H-ARQ level the grouping of ACK error indicator, also can create in the ARQ level.
Still with reference to figure 3, in order to ensure receiving H-ARQ NACK to the ACK error indicator, H-ARQ transmitter 314 can send ACK (step 410) to H-ARQ receiver 324.H-ARQ receiver 324 receive break down from the ACK of H-ARQ transmitter 314 or Radio Link before, H-ARQ receiver 324 can repeat to send H-ARQ NACK to the ACK error indicator.
When in step 408, receive H-ARQ NACK to the ACK error indicator after, unless reach maximum retransmission, the maximum delivered time expires and/or the failed packet expiration of time limit, otherwise H-ARQ transmitter 314 will be attempted in H-ARQ level restoration mistake (step 412) by retransmitting failed packet.H-ARQ transmitter 314 can send local ACK to ARQ transmitter 312, so that in ARQ level restoration failed packet (step 414).Preferably, only the maximum delivered time that reaches maximum retransmission, failed packet expire or the situation of the expiration of time limit of failed packet under, H-ARQ transmitter 314 just can send local NACK to ARQ transmitter 312.
In the prior art, in case successfully transmitted grouping, that one H-ARQ receiver 324 can send ACK to H-ARQ transmitter 314, and H-ARQ transmitter 314 can send local ACK to ARQ transmitter 312.According to the present invention, in this case, H-ARQ transmitter 314 both can send local ACK to ARQ transmitter 312, also can not send.
When in step 408, sent H-ARQ NACK to the ACK error indicator after, in step 416, H-ARQ receiver 324 will determine H-ARQ receiver 324 following condition has taken place in one of at least before whether successfully receive failed packet:
1) T RecoverySync(corresponding to H-ARQ transmission synchronously) or T RecoveryAsync(corresponding to asynchronous H-ARQ transmission) expires;
2) receive sequence number and exceed W than failed packet sequence number HARQNew H-ARQ grouping;
3) reach the maximum retransmission of failed packet;
4) timer T DeliveryAt the expiration; And
5) expiration of time limit of failed packet.
If at least one in the aforementioned condition, that one H-ARQ receiver 324 can send local NACK (step 418) to ARQ receiver 322.In case receive local NACK, ARQ receiver 322 can be to ARQ transmitter 312 status report, so that recover failed packet (step 420).When H-ARQ receiver 324 can be discerned the ARQ PDU that needs to recover, the reflection between ARQ PDU and the H-ARQ PDU was incoherent.
After the status report that receives from ARQ receiver 322, the ARQ buffer on the ARQ transmitter 312 can be cleared.The information that has comprised the grouping that receives about success about the status report of failed packet.As selection, ARQ receiver 322 also can successfully receive N continuously grouping or timer at the expiration after status report.As selection, ARQ transmitter 312 can also transmit the poll ARQ receiver 322 afterwards of last grouping in the buffer.The reason of implementing described poll is in order early to recover the NACK of last grouping to the ACK mistake in the H-ARQ level.Concerning data flow, " the poll bit that is used for last grouping " is set is configurable parameter.
For the recovery that improves last grouping in the H-ARQ transmission is handled, after having emptied the H-ARQ buffer, can send special little grouping from H-ARQ transmitter 314 with last grouping indication.By transmitting the particular packet that this has last grouping indication, can guarantee last grouping that recovery is early lost on the H-ARQ level.In case receive this particular packet, H-ARQ receiver 324 can send response to H-ARQ transmitter 314 is counter.This respond packet can be to be used to indicate the new grouping that receives last grouping what the H-ARQ level produced.As selection, this respond packet can also send by use H-ARQ mistake indication grouping, and wherein this H-ARQ mistake indication grouping represents that it is at described little response packet.
As selection,, after the ACK inspection of previous transmission has been called in last packet in the H-ARQ transmit queue, at this moment can send empty transmission in order to reduce signaling consumption.Empty grouping only comprises control information (just not having payload).H-ARQ transmitter 314 can transmit empty grouping after the H-ARQ ACK of last packet in receiving the H-ARQ transmit queue.In case H-ARQ receiver 324 receives empty grouping, that one H-ARQ receiver 324 will confirm to receive last packet and described empty grouping.If on the H-ARQ receiver, successfully do not receive last grouping, and sent NACK in response to described last grouping thus, and this moment, maximum transmission times did not reach as yet, and that youngest can make H-ARQ receiver 324 detection NACK to the ACK mistake by receiving described empty grouping.
Transmitter 310 and receiver 320 can be any network entities in WTRU, base station or WCDMA, CDMA2000 or the third generation (3G) system's Long Term Evolution (LTE)." WTRU " is including, but not limited to subscriber equipment (UE), mobile radio station, fixing or moving user unit, beep-pager, cell phone, personal digital assistant (PDA), computer or any subscriber equipment that can work in wireless environment." base station " be other any kind interface equipment in Node-B, site controller, access point or the wireless environment then.
