Background technology
Wireless telecommunication system allows wireless device to carry out communication under the situation that does not need wired connection.Because wireless system is integrated in the daily life, so need to support the wireless telecommunication system of multimedia service day by day, these multimedia services are speech, audio frequency, video, archives and page download or the like for example.In order to support the multimedia service of wireless device, developed various wireless telecommunication system and agreement, with the growth demand of the multimedia service of complying with the wireless telecommunications networking.
One of this kind agreement is broadband demal multitask (W-CDMA), and it is delivered by third generation Mobile Communications partnership project (3GPPTM), by the joint research of the machine-processed institute of how tame standard development.The broadcast interface of frequently taking action is opened up for a kind of broadband by W-CDMA system, and it uses direct sequence demal multitask (CDMA).
The communication of this wireless system can comprise single node (single-hop) transmission and multinode (multi-hop) transmission.In the single node wireless transmission, start node directly and destination node carry out communication.In comparison, in the multinode wireless transmission, the start node of wireless system can use one or more intermediate nodes (being sometimes referred to as via node) and carry out communication with destination node.In some system, via node can be described as relay station (relay station), and can be called transmission path with node between destination node with the combination that is connected at start node.The midsequent system can be present in the wireless network of any pattern.
Fig. 1 has multinode to transmit the sketch map of knowing wireless network 100 with the father-in-law of single node transmission.Wireless network 100 shown in Figure 1 is based on the standard of Institute of Electrical and Electronics Engineers (IEEE) 802.16 families.As shown in Figure 1; Wireless network 100 can comprise one or more transmitters (for example base station (BS) 110); One or more relay stations (RS) 120 (comprising RS 120a, 120b and 120c), and one or more subscriber station (SS) 130 (comprising SS 130a, 130b, 130c and 130d).
In wireless network 100; Start node (for example BS 110) and destination node are (for example; SS 130a, SS 130b, SS 130c, SS 130d etc.) between communication, can reach by one or more relay stations (for example, RS 120a, RS 120b, RS 120c etc.).For example, in wireless network 100, RS 120a can receive the data from BS 110, and these data are sent to another relay station (for example, RS 120b).Perhaps, RS 120a can receive the data from another relay station (for example, RS 120b), and is sent to BS 110.In another example, RS 120c can receive the data from RS120b, and these data are sent to subscriber station (for example SS 130a).Perhaps, RS 120c can receive the data from subscriber station (for example SS 130a), and is sent to domination relay station (for example RS120b).These are examples of multinode transmission.In the single node transmission of wireless network 100, can directly reach the communication between start node (for example BS 110) and destination node (for example SS 130d).For example, BS 110 can directly transmit data to SS 130d, and SS 130d can directly transmit data to BS 110.
The wireless system of the wireless network 100 of a kind of for example Fig. 1 can be realized medium access control (MAC) news frame (frame) form, and it uses the standard of IEEE 802.16 families of orthogonal frequency division multiple access (OFDMA).In wireless system 100, the transmission time may be partitioned into a plurality of adjustable length son news frames: cochain (UL) news frame and following chain (DL) news frame.Generally speaking, this UL news frame can comprise a plurality of range finding passages (ranging channels), channel quality information channel (CQICH) and a plurality of UL data Cong Xun (data burst) that comprise data.
DL news frame can comprise: preorder (preamble), news frame control header (FCH), DL figure (DL-MAP), UL figure (UL-MAP) and DL data Cong Xun zone.Preorder can be in order to provide synchronous.For example, this preorder can be in order to adjustment timing off-set, frequency shift (FS) and power.FCH can comprise each news frame control information that connects, and comprises the for example decoding information of SS 130.
DL figure and UL figure can be in order to the passage access of location cochain with following chain communication.That is this DL figure can be provided at the catalogue of access time slot (access slot) position in the present news of the chain down frame, and UL figure can be provided at the present catalogue that goes up the access time slot position in the chain news frame.In this DL figure, this kind catalogue can be one or more DL figure information assembly (MAP Information Element, forms MAPIE).Each MAP IE in this DL figure can comprise several parameters of single connection (that is, with being connected of single SS 130).These parameters can be in order to confirm interrogating in the frame position of data Cong Xun, the length of data Cong Xun, recipient's identity of data Cong Xun, and transmission parameter sub at present.
For example, each MAP IE can comprise: and connection ID (Connection ID, CID), the identity of the destination apparatus of its data discrimination Cong Xun (for example, SS 130a, SS 130b, SS 130c, SS 130d etc.); Following chain use at interval sign indicating number (Downlink Interval Usage Code, DIUC), sign indicating number is used in its expression down chain at interval, following chain transmission be by its define; The OFDMA symbol offset, the skew of the OFDMA symbol that its expression data Cong Xun begins; The subchannel skew, it is represented in order to transmit the minimum pointer OFDMA subchannel of this Cong Xun.Other parameter also can be included among this MAP IE, and for example, (boosting) parameter that raises, OFDMA symbolic representation parameter, subchannel are represented parameter etc.Known MAC header (for example FCH) can be called with MAP IE and be connected the conversion and control data.
DL figure and UL figure all can follow these data Cong Xun zone.Data Cong Xun zone can comprise one or more data Cong Xun.Each data Cong Xun in the data Cong Xun zone can be according to the control pattern of corresponding connection conversion and control data by modulation and coding.Generally speaking, DL figure and UL figure can be called the packet data unit (packet data unit, PDU) or abbreviate packet information as.
The used transmission controlling mechanism of the wireless network 100 of Fig. 1 such as be automatic repeat request (Automatic Repeat Request, ARQ).By using ARQ; The device of wireless system (for example, BS 110, RS120a, 120b and 120c, and SS 130a, 130b, 130c and 130d etc.) can be designed to; When packet information is not received or receives when wrong by the purpose recipient, it can transmit packet data again.The combination that ARQ transmission controlling mechanism can be used ACK, NACK and overtime (timeout) is with the Data transmission transmission state.The ARQ agreement can comprise: stop and wait (Stop-And-Wait (SAW)), get back to N (Go-Back-N) and selectivity and repeat.
In the wireless system that uses ARQ transmission controlling mechanism, when receiving system received (new or transmission) again packet data, receiving system can produce and transmit ACK or NACK conveyer so far.ACK confirms index signal, and it can be included in the message or be additional to message, and can be seen off to transmitter by receiver, has correctly received this transmission data with the expression receiver.NACK is the negative acknowledgment index signal, and it is included in the message or is additional to message, and can be seen off to transmitter by receiver, and the transmission data that received with indication have one or more mistakes.
Fig. 2 is sender Figure 200 of the operation of (end-to-end) ARQ transmission controlling mechanism between end points.As shown in Figure 2, in the distribute type resource configuration system, the next node in the transmission path in each node meeting Resources allocation to relay route.For example, in the distribute type resource configuration system, BS 110 can be RS 120a deploy resources, and it is denoted as the arrow between BS 110 and RS 120a.Likewise, RS 120a can be RS 120b deploy resources, and it is denoted as the arrow between RS 120a and RS 120b.In the centralized resources configuration-system, BS 110 all nodes in can control information transmission to transmission path, RS 120a for example, RS 120b, RS 120c and SS 130a are to accomplish resource distribution.In either case, after resource distribution was accomplished, BS 110 can be via intermediate node RS120a, RS 120b and RS 120c and Data transmission to destination node (SS 130a).In addition, BS 110 can store the data of seeing off copy in buffer.In the example of Fig. 2, this data is made up of eight (8) individual packet datas.
RS 120a can successfully receive this 8 packet datas, and the copy of storage data is to its buffer, and transmits these data to RS 120b.Yet, between RS 120a and RS 120b, maybe be owing to damage, interference, mistake etc. are lost 2 packet datas, so RS 120b possibly receive only 6 packet datas.RS 120b can transmit these 6 packet informations to RS 120c, and store transmit data copy to its buffer.Likewise, RS 120c can receive this 6 packet datas, transmits these 6 packet datas to SS 130a, and store transmit data copy to its buffer.Yet between RS 120c and SS 130a, 3 packet datas possibly lost in addition, cause having only 3 packet datas successfully to be received by SS 130a.When receiving these 3 packet datas, SS 130a can transmit the ACK index signal to BS 110 along the ul transmission path via RS 120c, RS 120b and RS 120c.The ACK index signal can inform that success receives this 3 packet datas.When BS 110 received this ACK index signal, BS 110 can remove these 3 packet datas that identified in buffer.
In case BS 110 has removed buffer, then BS 110 can prepare 3 new packet datas to transfer to SS 130a.In some cases, BS 110 can carry out communication with RS 120a, 120b and 120c, to determine the how transmission again of locator data, can make each RS 120 can receive the correct data of its most directly node in ul direction (that is, upper node).When BS 110 has determined how to locate when transmitting again, BS 110 can then utilize the centralization resource distribution, redeploys these resources along transmission path.Perhaps, carry out the distribute type resource distribution, each node can redeploy resource to next node along transmission path (cochain or following chain) in transmission path.In either case, in case these resources are redeployed, BS 110 can transmit these 3 new packet datas to SS 130a via RS 120a.
RS 120a can receive these data and 2 packet datas between RS 120a and RS 120b, being lost are added data so far, to transfer to RS 120b (that is, Data (2+3 ')) again.RS 120b can receive Data (2+3 '), transmission Data (2+3 ') to RS 120c, and stores new Data (that is, Data (3 ')) to its buffer.Likewise, RS 120c can receive Data (2+3 ') and these 3 packet datas that will between RS120c and SS 130a, be lost are added into Data (2+3 '), uses generation Data (5+3 ').RS 120c can transmit Data (5+3 ') to SS 130a, and the copy of stores new (that is, Data (3 ')) to its buffer.SS 130a can receive new data and transmit data (that is, Data (5+3 ')) again, and via RS 120a, RS 120b and RS 120c the transferring ACK index signal to BS 110.The ACK index signal that is transferred out is to inform to receive 8 packet datas (that is, ACK (5+3 ')), and wherein 3 packages are new data, the attach most importance to data of new transfer of 5 packages.When receiving the ACK index signal, BS 110 can remove its buffer.
Fig. 3 is sender Figure 30 0 of the operation of two-part ARQ transmission controlling mechanism.In the system that uses two-part ARQ transmission controlling mechanism; Access node (intermediate node RS 120a for example; 120b and 120c) return the ACK index signal to transmission node (for example BS 110), whether successfully received to represent present transmission state and this transmission by access node.Access node is the intermediate node (for example, RS 120a, RS 120b, RS 120c etc.) of directly communication to destination node (for example, SS 130a, SS 130b, SS 130c, SS 130d etc.).For example, the access node corresponding to SS 130a can be RS 120c.
Be similar to Fig. 2, Fig. 3 demonstrates, and all nodes that BS 110 can control information transmission to transmission path are to carry out resource distribution in the centralized resources configuration-system.For example, about the transmission path from BS 110 to SS 130a, BS 110 can carry out resource distribution for RS 120a, RS 120b, RS 120c and SS 130a.Under another situation, in the distribute type resource configuration system, each node in this transmission path can be along transmission path (cochain or following chain) deploy resources to next node.For example; About transmission path from BS 110 to SS 130a; BS 110 can carry out from the resource distribution of BS 110 to RS 120a; RS 120a can carry out the resource distribution from RS 120a to RS120b, and RS 120b can carry out the resource distribution from RS 120b to RS 120c, and RS 120c can carry out the resource distribution from RS 120c to SS 130a.In either case, in case resource distribution is accomplished, BS 110 can be via intermediate node RS 120a, RS 120b and RS120c and Data transmission to destination node (SS 130a).In addition, BS 110 can store the data of seeing off copy to buffer.In the example of Fig. 3, these data can comprise eight (8) individual packet datas.
RS 120a can successfully receive this 8 packet datas, and the copy that stores the data that receive is to its buffer, and the transmission data are to RS 120b.RS 120b can successfully receive this 8 packet datas, and the copy that stores the data that receive is to its buffer, and the transmission data are to RS 120c.Yet, between RS 120b and RS 120c, possibly lose 2 packet datas owing to damage, interference mistake etc., so RS 120c possibly only receive 6 packet datas.RS 120c can transmit in advance the ACK index signal to BS 110, to acknowledge receipt of this 6 packet datas.
In addition, RS 120c can transmit 6 the packet information that receives to SS 130a, and store transmit data copy to its buffer.Yet in the transmission between RS 120c and SS 130a, 4 packet datas possibly lost in addition, to cause having only 2 packet datas successfully to be received by SS 130a.Receiving that in 2 packet datas, SS 130a can transmit the ACK index signal to RS 120c.The ACK index signal can successfully be received this 2 packet informations by SS 130a in order to inform.Receiving in the ACK that RS 120c can transmit any data that success is received by SS 130a again.For example, in Fig. 3, RS 120c can be transmitted in transmission between RS 120c and the SS 130a and 4 packet datas of loss again.
When BS 110 received the ACK index signal from RS 120c, BS 110 can remove the buffer that is regarded as 6 packet datas that success receives by RS 120c.In case BS 110 has removed its buffer, then BS 110 can prepare 6 ' individual new packet data to transfer to SS 130a, together with 2 packet datas between RS 120b and RS 120c, losing.In some cases, BS 110 can carry out communication with RS 120a, 120b and 120c, transmits with the localization of determination data, in order to do making each RS 120 can be from receiving correct data along the most directly node of ul direction (that is, upper node) again.Yet in other cases, BS 110 can't carry out communication with RS 120a, 120b and 120c to be transmitted with the localization of determination data again.
When BS 110 has determined how to locate when transmitting again, in the system of centralization resource distribution, BS 110 can then redeploy these resources along transmission path.Perhaps, in the system of distribute type resource distribution, each node can redeploy resource to next node along transmission path (cochain or following chain) in transmission path.In either case, in case these resources are redeployed, BS 110 can transmit Data (2+6 ') to SS 130a via RS 120a.RS 120a can successfully receive Data (2+6 '), and the transmission Data that receives (2+6 ') is to RS 120b, and the copy of storage Data (2+6 ') is in its buffer.RS 120b can successfully receive Data (2+6 '), and the transmission Data that receives (2+6 ') is to RS 120c, and the copy of storage Data (2+6 ') is in its buffer.Likewise, RS 120c can receive Data (2+6 '), and the transmission Data that receives (2+6 ') is to RS 120b, and the copy of storage Data (2+6 ') is in its buffer.In addition, RS 120c can transmit the ACK index signal to BS 110, to acknowledge receipt of successfully the data that received by RS 120c (that is, ACK{2+6 ' }).
SS 130a can receive new data and transmit data (that is, Data (2+6 ')) again, and the transferring ACK index signal is to RS 130c.The ACK index signal can confirm successfully to receive the individual packet information of 2+6 ' (that is, ACK (2+6 ')), and wherein 6 ' individual package is a new data, 2 packages new transfer data of attaching most importance to.Receiving that in the ACK index signal, RS 130c can remove new data and the legacy data in its buffer, wherein these new data data and legacy data are to be designated as successfully received data by SS 130a.
Because the hop count of transmission path increases, compared to the single node wireless network, the error detection of multinode wireless network and the effect of correction are even more important.Therefore, in the multinode transmission, traditional error detection possibly cause cost significantly to increase with correction, the long delay and the wasting of resources.
Described enforcement example is in order to overcome the problems referred to above.

Fig. 6 shows the flow chart of data processing Figure 60 0 in the wireless telecommunication system (for example wireless telecommunication system 400) of the embodiment of the invention.Particularly, Fig. 6 shows that RS 440 receives the processing of packet data from upper (superordinate) RS440, or BS 430 receives packet datas and delivers to the processing of the next (subordinate) RS 440 or SS 450.At this, " the next " is in order to the relative position of a node to another node to be described with " upper ".The next node is to be the node in the following chain stream of waiting to discuss between node and the receiving node SS 450.Upper node is to be the node in the cochain stream of waiting to discuss between node and the BS430.
As shown in Figure 6, RS 440 possibly receive the packet data (step 605) from BS 430 or upper RS 440.Use control information; RS 440 possibly determine whether received packet data will transfer to access RS 440 (for example RS 440c) or SS 450 (step 610); Wherein control information comprise receive in the packet data the packet data header information and/or figure information assembly (informationelement, IE).If this packet data does not transfer to access RS 440 (for example RS 440c) or SS450 (step 610 denys), RS 440 possibly handle and give up the packet data (step 620) of sign like this.In an embodiment, this packet data possibly be contained in and receive in the data packet.Perhaps, this packet data possibly be the data before seen off or follow-up data packet.
Yet if this packet data will be transferred to access RS 440 (for example RS 440c) or SS 450 (step 610 is), RS 440 possibly determine whether the data that receive comprise one or more data packets (step 615) of transmission again.Again the data packet of transmission means, has before transferred to RS 440 but because transmission fault or mistake need the data packet that transmits again.Again the packet data of transmission possibly be included in the data packet with new data, or possibly seen off in only comprising the data packet that transmits data again.In an embodiment, the packet data of transmission possibly be before by the data index signal (indicator) or the identification signal (identifier) of the buffer of RS 440 that RS 440 receives and is stored in again.Whether RS 440 possibly use the resource allocation information of before having been seen off by control station (for example BS 430 or upper RS440), serve as transmission packet data or for transmitting packet data again to determine this packet data.If in this data packet, comprise the single packet data of transmission again, RS440 will determine received data to comprise to transmit packet data again.
If the data that RS 440 decisions receive comprise one or more data packet (steps 615 of transmission again; Be); Then RS 440 possibly transfer to access RS 440 (for example, RS 440c) or SS 450 (step 625) together with the new data packet in the received data again with this packet data.In an embodiment, RS 440 maybe be from obtaining the packet data that will transmit again from its buffer, and use the resource allocation that these data are transmitted again to come to transmit again this packet data.If this packet data is for transmitting data again, then RS 440 possibly receive only the control data from upper BS 430 or RS 440.That is received data possibly only comprise flow and/or application data, and do not have user's data.Do not transmit data (step 615 denys) again if this packet data does not comprise, RS 440 maybe be with the received packet data transmission that comprises control information and/or user's data to access RS 440 (for example, RS 440c) or SS 450 (step 630).
Though be not shown among Fig. 6; If RS 440 is provided with relaying transmit timing device again; When transmitting (step 630) and/or transmitting (step 625) again, the relaying that RS 440 the sets value of transmit timing device again can reflect the RS 440 total round-trip transmission time T between the datum target node therewith Total
Fig. 7 shows the flow chart of data processing Figure 70 0 according to the wireless telecommunication system (for example wireless telecommunication system 400) of an enforcement example of the present invention.Particularly, Fig. 7 shows that RS 440 receives ACK (affirmation) and NACK (negative acknowledgment) index signal from SS 450 or RS 440, to transfer to upper RS 440 or BS 430.
As shown in Figure 7, RS 440 possibly receive ACK or the NACK index signal (step 705) of self-access RS 440 (for example RS 440c) or SS 450.In the data packet of confirming to be seen off by BS 430 which these ACK or NACK index signal possibly successfully received by access RS 440 (for example RS440c) or SS 450 in order to.For example; If BS 430 transmits 8 packet datas (for example data packet 1-8); But access RS 440 (for example RS 440c) or SS 450a receive only 6 data packages (for example data packet 1,3,4,5,6 and 8), and the ACK index signal possibly be that which that successfully receive (for example data packet 1,3,4,5,6 and 8) and/or these 8 data packages is not successfully to receive (for example data packet 2 and 7) in order to confirm in these 8 data packages which.Whether RS440 successfully receives the identification signal of packet data possibly directly and/or indirectly accomplished.That is ACK and/or NACK index signal possibility by confirming received packet data and/or the packet data that does not receive, come directly to confirm received packet data; Or by distinguishing that a certain person who successfully receives packet data provides information, with indirect acknowledgment.
After receiving ACK or NACK index signal, RS 440 possibly relatively be contained in information and the buffer status information (step 710) in ACK or the NACK index signal.In one embodiment, RS 440 possibly compare ACK or NACK index signal information and buffer information, with the packet data of confirming that destination node (that is, SS 450a) receives.Based on this relatively, RS 440 possibly determine whether need a RACK index signal (step 715).If (step 715, not), then RS 440 possibly transfer to upper RS 440 or BS 430 with ACK that receives or NACK index signal not need the RACK index signal.
Yet, RACK index signal (step 715 is) if desired, RS 440 possibly revise received index signal, to comprise RACK index signal (step 720).For example, the RACK index signal that RS440 comprised has received ACK or NACK index signal, and ACK or NACK index signal are transferred to upper RS440 or BS 430 (step 725) with the RACK index signal that is comprised.Perhaps, RS 440 possibly revise header information and successfully received and transferred to the packet data of SS 450 by upper BS 430 or RS 440 to distinguish RS 440.
Fig. 8 shows according to the flow chart of data processing Figure 80 0 of enforcement example in wireless telecommunication system (for example wireless telecommunication system 400) of the present invention.Particularly, Fig. 8 shows, when ACK or NACK index signal not relevant relaying again the transmit timing device expire when being received by RS 440 before the situation of the generation RACK index signal of RS440.
As shown in Figure 8; If this relaying is transmit timing device before RS 440 receives ACK or NACK index signal, expire (step 805) again; Then RS 440 possibly produce the RACK index signal automatically, and the RACK index signal that is produced is sent to upper RS 440 or BS 430 (step 810).When RS 440 produces the RACK index signals automatically, but it is not when receiving from the ACK of SS 450 or NACK index signal, and the information that transfers to upper RS 440 or BS 430 can't comprise ACK or NACK index signal.The substitute is, information will only comprise the RACK information of RS 440.
Fig. 9 implements the error detection of example and sender Figure 90 0 of correction mechanism according to of the present invention one.Particularly, Fig. 9 discloses a kind of embodiment of two sections ARQ, and wherein communication is to result from two sections: at transmitter (for example; BS 430) with access node (for example, RS 440c) between, and (for example at access node; RS 440c) with user's set (for example, SS 450a) between.In Fig. 9; The RACK index signal possibly be transmitted in transmission path relaying ARQ section (that is; Between transmitter and access node), and ACK and/or NACK index signal possibly be transmitted in the access ARQ section (that is, between access node and receiving system) of transmission path.Clearer and more definite, in Fig. 9, ACK and/or NACK index signal possibly be sent to BS 430 from SS 450a, and the RACK index signal possibly be sent to BS 430 from RS 440c.In addition, in the system of the sender mechanism that adopts Fig. 9, can use distribute type or the resource distribution of centralized resources arranged for executing.
As shown in Figure 9, but BS 430 control information transmissions to all nodes in set transmission path, and for example RS 440a, RS 440b, RS 440c and SS 450a are in order to carry out resource distribution (that is, centralized resources configuration).After resource distribution was done, BS 430 can transmit packet data to destination node (for example RS 440c or SS 450a) via one or more intermediate nodes (for example RS 440a, RS 440b and RS 440c).In addition, BS 430 can store in copy to a buffer of seeing packet data off.In the example of Fig. 9, packet data be by 8 data packages (that is, Data (8)) form.
RS 440a can successfully receive Data (8), and the copy that stores packet data is to its buffer, and the transmission packet data is to RS 440b.Likewise, RS 440b can successfully receive Data (8), and the copy that stores packet data is to its buffer, and the transmission packet data is to RS 440c.Yet between the transmission period of RS440b to RS 440c, 2 packet datas maybe be owing to damage, interference, mistake etc. be lost, and RS 440c possibly receive only 6 packet datas (that is, Data (6)).Receiving in the Data (6), RS 440c can produce a RACK index signal (that is, RACK{6}), and transmit the RACK index signal that produced to its upper node R S 440b.The RACK index signal that is produced can confirm 8 data packages that BS 430 is seen off which be successfully to receive by RS 440c.RACK{6} possibly transfer to RS 440a from RS 440b along the ul transmission path, then to BS430.
Except producing and transmit the RACK index signal, RS 440c also can pass on the packet data that received (that is, Data (6)) to SS 450a.Yet between RS 440c and SS 450a, in addition 4 packet datas possibly lost, and cause having only 2 packet datas (that is, Data (2)) successfully to be received by SS 450a.Receiving in the Data (2) that SS 450a can produce and transmit ACK index signal (that is, ACK (2)) to RS 440c, to confirm successfully received 2 packet datas.As above combine the explanation of Fig. 6, RS 440c can relatively contain the information of ACK index signal and the data that were stored in its buffer in the past.Based on this relatively, RS 440c can transfer to SS 450a again with any data that successfully do not received by SS 450a.For example, as shown in Figure 9, RS 440c can be transmitted in 4 packet datas losing between RS 440c and the SS 450a again.Also as shown in Figure 9, SS 450a can successfully receive 4 packet datas.Therefore, SS 450a can produce and transmit an ACK index signal (that is, ACK (4)) and to RS 440c, successfully receive data to indicate it.
When RS 440c transmits any packet data that is lost between RS 440c and the SS 450a again, BS 430 can receive the RACK index signal seen off from RS 440c (that is, RACK{6}).BS 430 decodable code RACK index signals are determining to the transmission state of the packet data of RS 440c, and based on decoding, BS 430 can remove its buffer packet data that is successfully received by RS 440c.BS 430 can prepare new packet data transferring to SS 450a via RS 440c, and new packet data is sent to RS 440c together with any packet data of treating to transmit again.For example, BS 430 can remove 6 Datagrams for successfully being received by RS 440c that are shown in the RACK index signal, and prepares 6 ' individual new data packet for transmission.In addition, BS 430 can redeploy resource along transmission path.
In case these resources are redeployed, BS 430 can transmit the data packet (that is, Data (2+6 ')) of new and transmission again to RS 440a.RS 440a can successfully receive Data (2+6 '), and the copy that stores packet data is to its buffer, and transmits packet data to RS 440b.Likewise, RS 440b can successfully receive Data (2+6 '), and the copy that stores packet data and transmits packet data to RS 440c to its buffer.Receiving in the Data (2+6 ') that RS 440c can produce a RACK index signal (that is, RACK{2+6 ' }), and transmitting the RACK index signal that produced to its upper node R S 440b.The RACK index signal that is produced can be confirmed the individual data package of 2+6 ' being seen off and successfully received by RS 440c by BS 430.The RACK index signal that is produced (that is, RACK{2+6 ' }) possibly transfer to RS 440a from RS 440b along the ul transmission path, then to BS430.
Except producing and transmit the RACK index signal, RS 440c also can pass on the packet data that received (that is, Data (2+6 ')) to SS 450a.Receiving that in the individual packet data of 2+6 ', SS 450a can transmit an ACK index signal to RS 440c, to confirm the individual packet data of successfully received 2+6 '.As above combine the explanation of Fig. 6, RS 440c can relatively contain the information of ACK index signal and the data that were stored in its buffer in the past.Based on this relatively, RS 440c can transfer to SS 450a again with any data that successfully do not received by SS 450a.Yet as shown in Figure 9, SS 450a successfully receives the individual packet data of 2+6 '.
Though Fig. 9 shows the transmission that the ACK index signal begins from SS 450a, SS 450a can transmit the ACK and/or the NACK index signal of any combination.Under a situation, error detection will be proceeded with correction, as stated.Again, though sender Figure 90 0 is presented in the single transmission path enforcement example of using three RS 440, people are contemplated to the number of the RS 440 in a transmission path can be greater or less than the number that is shown.In addition, though be not shown among Fig. 9, between the transmission period of new data and at again between transmission period of data, also can use relaying transmit timing device again.
Figure 10 implements the error detection of example and sender Figure 100 0 of correction mechanism according to of the present invention one.Particularly, Figure 10 shows a kind of embodiment of two sections ARQ, and wherein communication is to result from two sections: at transmitter (for example; BS 430) with access node (for example, RS 440c) between, and (for example at access node; RS 440c) with user's set (for example, SS 450a) between.In Figure 10; The RACK index signal possibly be transmitted in transmission path relaying ARQ section (that is; Between transmitter and access node), and ACK and/or NACK index signal possibly be transmitted in the access ARQ section (that is, between access node and receiving system) of transmission path.Clearer and more definite, in Figure 10, ACK and/or NACK index signal possibly be sent to BS 430 from SS 450a, and the RACK index signal possibly be sent to BS 430 from RS 440c.In addition, the scheme that Figure 10 shows is RS 440c generation and transmits a RACK index signal to BS 430 that RS 440c receives an ACK index signal from SS 450a simultaneously.
In the sender figure of Figure 10, resource distribution can cooperate the explanation that Fig. 9 does and proceed.After accomplishing resource distribution, BS 430 can transmit packet data to destination node (for example SS 450a) via one or more intermediate nodes (for example, RS440a, RS 440b and RS 440c).In addition, BS 430 can store copy to a buffer of seeing packet data off.In the example of Figure 10, packet data system is made up of 8 data packages (that is, Data (8)).
RS 440a can successfully receive Data (8), and the copy that stores packet data is to its buffer, and the packet data that transmission is received is to RS 440b.Likewise, RS 440b can successfully receive Data (8), and the copy that stores packet data is to its buffer, and the packet data that transmission is received is to RS 440c.Yet between the transmission period of RS 440b to RS 440c, 2 packet datas possibly disturb owing to damage, mistake etc. and losing.Therefore, RS 440c possibly receive only 6 packet datas (that is, Data (6)).Receiving Data (6) afterwards, RS 440c can transmit Data (6) to SS 450a, and store transmit packet data copy to its buffer.
Between RS 440c and SS 450a, in addition 4 packet datas possibly lost, and cause having only 2 packet datas (that is, Data (2)) successfully to be received by SS 450a.Receiving in the Data (2) that SS 450a can transmit an ACK index signal (that is, ACK (2)) to RS 440c, to confirm successfully received data packet.Receiving in the ACK index signal (that is ACK (2)), RS 440c can produce a RACK index signal (that is, RACK{6}).The RACK index signal that is produced can confirm 8 data packages that BS 430 is seen off which be successfully to receive by RS 440c.RS 440c received ACK index signal capable of using (that is, ACK (2)) comprise the RACK index signal that produced (that is, RACK{6}), and both are transferred to RS 440b from RS 440c along the ul transmission path, RS 440a is then to BS 430.
Except producing and transmitting the RACK index signal, RS 440c also can attempt being transmitted in again any packet data of losing between RS 440c and the SS 450a.As above combine the explanation of Fig. 6, RS440c can relatively be contained in the information of ACK index signal and the packet data that was stored in its buffer in the past.In other embodiment, ACK index signal information that RS 440c can be more received and the data that stored in the past are to determine the quantity and/or the identification of the data that SS 450a is received.In other embodiment, RS 440c can only check received ACK index signal information.
Based on this relatively, RS 440c can transfer to SS 450a again with any data that successfully do not received by SS 450a.For example, shown in figure 10, RS 440c can be transmitted in 4 packet datas losing between RS 440c and the SS 450a (that is, Data (4)) again.In this, yet SS 450a possibly receive only 4 wherein 3 of data packets of transmission again (that is, Data (3)).Therefore, SS 450a can produce and transmit an ACK index signal confirms successfully to be received by SS 450a to RS 440c 3 data packets of transmission (that is, ACK (3)) again.When RS 440c receive the ACK index signal (that is; ACK (3)) time; RS 440c can compare at present received ACK index signal information (that is, ACK (3)) and in the past received ACK index signal information (that is, ACK (2)); To obtain an ACK index signal, it is confirmed successfully by the quantity and/or the identification of the data of SS 450a reception.In other embodiment, RS 440c can only check received ACK index signal information.In addition, RS 440c can be transmitted in 1 packet data losing between RS 440c and the SS 450a (that is, Data (1)) again.
Receiving successfully in 1 Datagram (that is, Data (1)) that SS 450a can produce an ACK index signal (that is, ACK (1)), and transmitting the ACK index signal that produced to RS 440c.RS 440c can compare at present received ACK index signal information (that is; ACK (1)) with in the past received ACK index signal information (that is; ACK (5)), to obtain the ACK index signal of a renewal, it is confirmed successfully by the quantity and/or the identification of the data of SS 450a reception.In other embodiment, RS 440c can only check received ACK index signal information.In this example, the ACK index signal can be confirmed 6 data packages seeing off and successfully received by SS 450a from RS 440c.
When RS 440c was transmitted in any packet data of losing between RS 440c and the SS 450a again, BS 430 can receive ACK and the RACK index signal of seeing off from RS 440c.BS 430 decodable code ACK and RACK index signal are with the transmission state of the packet data of the access ARQ section of relaying ARQ section and the transmission path of decision transmission path.Based on this decoding, BS 430 can remove the packet data that is successfully received by SS 450a from its buffer.BS 430 can prepare new packet data transferring to SS 450a via RS 440c, and transmit new packet data and any packet data of treating to transmit again to RS 440c.For example, BS 430 can remove 2 Datagrams for successfully being received by SS 450a that are shown in the ACK index signal, and prepares 2 ' individual new data packet for transmission.Though show, but can be disposed again, as above about the explanation of Fig. 9 along the resource of transmission path.
In case these resources are redeployed, BS 430 can transmit the data packet (that is, Data (2+2 ')) of new and transmission again to RS 440a.RS 440a can successfully receive Data (2+2 '), and the copy that stores packet data is to its buffer, and transmits packet data to RS 440b.Likewise, RS 440b can successfully receive Data (2+2 '), and the copy that stores packet data and transmits packet data to RS 440c to its buffer.Receiving in the individual packet data of 2+2 ' that RS 440c can pass on the packet data that received to SS 450a.Receiving that in the Data (2+2 '), SS 450a can transmit an ACK index signal to RS 440c, to confirm the individual packet data of successfully received 2+2 ' (that is, ACK (2+2 ')).As above combine the explanation of Fig. 6, RS 440c can relatively contain the information (that is, ACK (2+2 ')) and the data that were stored in its buffer in the past of ACK index signal.Based on comparing, RS 440c can not transfer to SS 450a again with any data that successfully received by SS 450a.In this, SS450a successfully receives Data (2+2 '), and the ACK index signal can be represented such situation.
RS 440c can compare at present received ACK index signal information (that is, ACK (2+2 ')) and received ACK index signal information in the past, with the quantity of the data confirming successfully to be received by SS 450a and/or identification (that is, ACK (8+2 ')).In this example, 8 initial data packages that the ACK index signal can be confirmed successfully to be received by SS 450a and 2 ' individual new data package.In addition, RS 440c can produce a RACK index signal (that is, RACK{2+2 ' }), confirms the 2+2 ' data packet that is successfully received by RS 440c.Received ACK index signal before the RACK index signal that is produced (that is, RACK{2+2 ' }) can include (that is, ACK (8+2 ')), and see 440a off from RS 440b to RS along the ul transmission path, then to BS 430.
Though Figure 10 shows the transmission that the ACK index signal begins from SS 450a, SS 450a can transmit the ACK and/or the NACK index signal of any combination.Under a situation, error detection will be proceeded with correction, as stated.Again, though sender Figure 100 0 is presented in the single transmission path enforcement example of using three RS 440, people are contemplated to the number of the RS 440 in a transmission path can be greater or less than the number that is shown.In addition, though be not shown among Figure 10, between the transmission period of new data and at again between transmission period of data, also can use relaying transmit timing device again.
Figure 11 implements the error detection of example and sender Figure 110 0 of correction mechanism according to of the present invention one.Particularly, Figure 11 shows a kind of embodiment of two sections ARQ, and wherein communication is to result from two sections: at transmitter (for example; BS 430) with access node (for example, RS 440c) between, and (for example at access node; RS 440c) with user's set (for example, SS 450a) between.In Figure 11; The RACK index signal possibly be transmitted in transmission path relaying ARQ section (that is; Between transmitter and access node), and ACK and/or NACK index signal possibly be transmitted in the access ARQ section (that is, between access node and receiving system) of transmission path.Clearer and more definite, in Figure 11, ACK and/or NACK index signal possibly be sent to BS 430 from SS 450a, and the RACK index signal possibly be sent to BS 430 from RS 440c.
In the sender figure of Figure 11, resource distribution can cooperate the explanation that Fig. 9 does and proceed.After accomplishing resource distribution, BS 430 can transmit packet data to destination node (for example SS 450a) via one or more intermediate nodes (for example, RS440a, RS 440b and RS 440c).In addition, BS 430 can store copy to a buffer of seeing packet data off.In the example of Figure 11, packet data be by 8 data packages (that is, Data (8)) form.
RS 440a can successfully receive Data (8), and the copy that stores packet data is to its buffer, and the packet data that transmission is received is to RS 440b.Likewise, RS 440b can successfully receive Data (8), and the copy that stores packet data is to its buffer, and the packet data that transmission is received is to RS 440c.Yet between the transmission period of RS 440b to RS 440c, 2 packet datas possibly disturb owing to damage, mistake etc. and losing.Therefore, RS 440c possibly receive only 6 packet datas (that is, Data (6)).RS 440c can transmit Data (6) to SS 450a, and store transmit packet data copy to its buffer.Yet between RS 440c and SS 450a, in addition 2 packet datas possibly lost, and cause having only 4 packet datas successfully to be received (that is, Data (4)) by SS 450a.Therefore, SS 450a can transmit an ACK index signal to RS 440c, to confirm successfully received 4 packet datas.
Receiving in the ACK index signal (that is, ACK (4)), RS 440c can produce a RACK index signal (that is, RACK{6}).The RACK index signal that is produced can confirm 8 data packages that BS 430 is seen off which be successfully to receive by RS 440c.RS 440c received ACK index signal capable of using (that is, ACK (4)) comprise RACK{6}, and both are transferred to RS 440b from RS 440c along the ul transmission path, RS 440a is then to BS 430.
Except producing and transmitting the RACK index signal, RS 440c also can attempt being transmitted in again any packet data of losing between RS 440c and the SS 450a.As above combine the explanation of Fig. 6, RS440c can relatively be contained in the information of ACK index signal and the data that were stored in its buffer in the past.Based on this relatively, RS 440c can transmit any data that successfully do not received by SS 450a again.For example, shown in figure 11, RS 440c can be transmitted in 2 packet datas losing between RS 440c and the SS 450a (that is, Data (2)) again.In this example, SS 450a possibly receive only 21 of data packets of transmission again (that is, Data (1)).Therefore, SS 450a can produce and transmit an ACK index signal to RS 440c, with confirm 2 again which (that is, ACK (1)) of the data packets of transmission can successfully be received.
When RS 440c received ACK index signal (that is, ACK (1)), RS 440c can be transmitted in 1 packet data losing between RS 440c and the SS 450a (that is, Data (1)) more again first between transmission period.Receiving successfully in 1 data package that SS 450a can produce an ACK index signal (that is, ACK (1)), and transmitting the ACK index signal that produced to RS 440c.RS440c can compare at present received ACK index signal information (that is, ACK (1)) and in the past received ACK index signal information (that is, ACK (1)), to obtain the ACK index signal (that is, ACK (2)) upgraded.In this example, the ACK index signal of renewal can confirm to transfer to again 2 the data packages that have only of SS 440c.
When RS 440c was transmitted in any packet data of losing between RS 440c and the SS 450a again, BS 430 can receive ACK and the RACK index signal of seeing off from RS 440c.BS 430 decodable code ACK and RACK index signal are with the transmission state of the packet data of the access ARQ section of relaying ARQ section and the transmission path of decision transmission path.In this example, based on this decoding, BS 430 can remove the packet data that is successfully received by SS 450a from its buffer.BS 430 can prepare new packet data transferring to SS 450a via RS 440c, and transmit new packet data and any packet data of treating to transmit again to RS 440c.For example, BS 430 can remove by ACK (4) and be identified as 4 Datagrams that successfully received by SS 450a, and prepares " k " individual new data packet for transmission.In this, k possibly be any integer.Though show, but can be disposed again, as above about the explanation of Fig. 9 along the resource of transmission path.
In case these resources are redeployed, BS 430 can transmit the data packet (that is, Data (2+k)) of new and transmission again to RS 440a.RS 440a can successfully receive Data (2+k), and the copy that stores packet data is to its buffer, and the transmission packet data is to RS 440b.Likewise, RS 440b can successfully receive Data (2+k), and the copy that stores packet data is to its buffer, and the transmission packet data is to RS 440c.Receiving in the Data (2+k) that RS 440c can pass on new and packet data transmission again (that is, Data (2+k ')) to SS 450a.In this, k ' can be any integer, and can be with reference to the new data transmission between RS 440c and SS 450a.In other embodiment, k ' maybe be identical with k.In other embodiment, k ' possibly be different from k.In either case, RS 440c can determine the content of k '.
Receiving that in the Data (2+k '), SS 450a can transmit an ACK index signal to RS 440c, confirming the package (that is, ACK (2+k ')) of successfully received Data (2+k ').As above combine the explanation of Fig. 6, RS 440c can relatively contain the information of ACK index signal and the data that were stored in its buffer in the past.Based on this relatively, RS 440c can transfer to SS 450a again with any data that successfully do not received by SS 450a.Yet shown in figure 11, SS 450a successfully receives the individual packet data of 2+k ', and transmits a corresponding ACK index signal (that is, ACK (2+k ')) to RS 440c.RS 440c can compare at present received ACK index signal information (that is; ACK (2+k ')) and former received ACK index signal information (that is; ACK (2); Obtaining the ACK index signal upgraded, the quantity of the data that it confirms successfully to be received by SS 450a and/or identification (that is, ACK (4+k ')).In this example, the ACK index signal can confirm not to be sent in the past about an ACK 4 initial data packages of BS 430, and the individual new data packet of k ' that is successfully received by SS 450a.
In addition, RS 440c can produce a RACK index signal (that is, RACK{2+k ' }), the package of the Data that confirms successfully to be received by RS 440c (2+k ').The RACK index signal that is produced (that is, RACK{2+k ' }) possibly include ACK index signal (that is, ACK (4+k ')), and sees the 440b to RS along the ul transmission path off from RS 440c, and RS 440a is then to BS 430.
Though Figure 11 shows the transmission that the ACK index signal begins from SS 450a, SS 450a can transmit the ACK and/or the NACK index signal of any combination.Under a situation, error detection will be proceeded with correction, as stated.Again, though sender Figure 110 0 is presented in the single transmission path enforcement example of using three RS 440, people are contemplated to the number of the RS 440 in a transmission path can be greater or less than the number that is shown.In addition, though be not shown among Figure 11, between the transmission period of new data and at again between transmission period of data, also can use relaying transmit timing device again.
Figure 12 implements the error detection of example and sender Figure 120 0 of correction mechanism according to of the present invention one.Particularly, Figure 12 shows a kind of embodiment of two sections ARQ, and wherein communication is to result from two sections: at transmitter (for example; BS 430) with access node (for example, RS 440c) between, and (for example at access node; RS 440c) with user's set (for example, SS 450a) between.In Figure 12; The RACK index signal possibly be transmitted in transmission path relaying ARQ section (that is; Between transmitter and access node), and ACK and/or NACK index signal possibly be transmitted in the access ARQ section (that is, between access node and receiving system) of transmission path.Clearer and more definite, in Figure 12, ACK and/or NACK index signal possibly be sent to BS 430 from SS 450a, and the RACK index signal possibly be sent to BS 430 from RS 440c.In Figure 12, in case RS 440c produces and transmits a RACK index signal to BS 430, then any ACK and/or NACK index signal that receives subsequently possibly transferred to BS 430 by RS 440c.
In the sender figure of Figure 12, resource distribution can cooperate the explanation that Fig. 9 does and proceed.After accomplishing resource distribution, BS 430 can transmit packet data to destination node (for example SS 450a) via one or more intermediate nodes (for example, RS440a, RS 440b and RS 440c).In addition, BS 430 can store copy to a buffer of seeing packet data off.In the example of Figure 12, packet data be by 8 data packages (that is, Data (8)) form.
RS 440a can successfully receive Data (8), and the copy that stores packet data is to its buffer, and the transmission packet data is to RS 440b.Likewise, RS 440b can successfully receive Data (8), and the copy that stores packet data is to its buffer, and the transmission packet data is to RS 440c.Yet between the transmission period of RS440b to RS 440c, 2 packet datas possibly disturb owing to damage, mistake etc. and losing.Therefore, RS 440c possibly receive only 6 packet datas (that is, Data (6)).Therefore, RS 440c can only transmit Data (6) to SS 450a, and store transmit packet data copy to its buffer.Between RS 440c and SS 450a, in addition 4 packet datas possibly lost, and cause having only 2 packet datas (that is, Data (2)) successfully to be received by SS 450a.Receiving that in 2 packet datas, SS 450a can transmit an ACK index signal to RS 440c, to confirm successfully received 2 packet datas.Receiving in the ACK index signal (that is, ACK (2)), RS 440c can produce a RACK index signal (that is, RACK{6}).The RACK index signal that is produced can confirm 8 data packages that BS 430 is seen off which successfully received by RS 440c.RS 440c received ACK index signal capable of using (that is, ACK (2)) comprise RACK{6}, and two index signals are transferred to RS 440b from RS 440c along the ul transmission path, RS 440a is then to BS 430.
Except producing and transmitting the RACK index signal, RS 440c also can attempt being transmitted in again any packet data of losing between RS 440c and the SS 450a.As above combine the explanation of Fig. 6, RS440c can relatively be contained in the information of ACK index signal and the data that were stored in its buffer in the past.Based on this relatively, RS 440c can transmit any data that successfully do not received by SS 450a again.For example, shown in figure 12, RS 440c can be transmitted in 4 packet datas losing between RS 440c and the SS 450a (that is, Data (4)) again.In this example, SS 450a can receive only 4 wherein 3 of data packets of transmission again (that is, Data (3)).Therefore, SS 450a can produce and transmit an ACK index signal to RS 440c, to confirm successfully received 3 data packets of transmission (that is, ACK (3)) again.When RS 440c received ACK index signal (that is, ACK (3)), RS 440c can pass on received ACK index signal to RS 440b from RS 440c along the ul transmission path, and RS 440a is then to BS 430.In addition, RS 440c can be transmitted in 1 packet data losing between RS 440c and the SS 450a (that is, Data (1)) again.Receiving in 1 Datagram (that is, Data (1)) of success, SS 450a can produce an ACK index signal (that is, ACK (1)), and transmits the ACK index signal that produced to RS 440c.Again, when RS 440c received ACK index signal (that is, ACK (1)), RS 440c can pass on received ACK index signal to RS 440b from RS 440c along the ul transmission path, and RS 440a is then to BS 430.This can proceed, and has successfully transmitted all data packets till the SS 450a up to RS 440c.
Though Figure 12 shows the transmission that the ACK index signal begins from SS 450a, SS 450a can transmit the ACK and/or the NACK index signal of any combination.Under a situation, error detection will be proceeded with correction, as stated.Again, though sender Figure 120 0 is presented in the single transmission path enforcement example of using three RS 440, people are contemplated to the number of the RS 440 in a transmission path can be greater or less than the number that is shown.In addition, though be not shown among Figure 12, between the transmission period of new data and at again between transmission period of data, also can use relaying transmit timing device again.Moreover in other embodiment, RS 440c can produce and transmit an independent ACK index signal to BS 430.One independent ACK index signal possibly be an ACK index signal, and it is produced by RS440 (for example, RS 440c).Independent ACK index signal by Event triggered (for example possibly belong to; In one or more ACK and/or NACK index signal is to see off during from receptions such as SS 450a); Maybe possibly be (for example to be triggered termly; Periodic interval in being predetermined is seen off, see off when the transmit timing device expires again at relaying, one or more other timers and/or the sequential incident expires and/or be to see off when surpassing etc.).In addition, in other embodiment, access RS 440 (for example, RS 440c) can produce and transmit an independent RACK index signal to BS 430.For example, if an ACK and/or NACK index signal did not receive from SS 450a before a trigger event produces, then access RS 440 can produce and transmit an independent RACK index signal.The example of trigger event comprises: when receive an ACK index signal from SS 450a; At a distance from when surpass between one periodicity that is predetermined; When one relaying transmit timing device again expires, and when one or more other timers and/or sequential incident expire and/or be to surpass etc.In other embodiments; Access RS 440 (for example; RS 440c) can compare buffer state; Wherein before any trigger event produced, if access RS 440 receives one or more ACK index signals from SS 450, then access RS 440 was accompanied by the one or more ACK index signals that received and produces and transmit a RACK index signal.
Figure 13 implements the error detection of example and sender Figure 130 0 of correction mechanism according to of the present invention one.Particularly, Figure 13 shows a kind of embodiment of two sections ARQ, and wherein communication is to result from two sections: at transmitter (for example; BS 430) with access node (for example, RS 440c) between, and (for example at access node; RS 440c) with user's set (for example, SS 450a) between.In Figure 13; The RACK index signal possibly be transmitted in transmission path relaying ARQ section (that is; Between transmitter and access node), and ACK and/or NACK index signal possibly be transmitted in the access ARQ section (that is, between access node and receiving system) of transmission path.Clearer and more definite, in Figure 13, ACK and/or NACK index signal possibly be sent to BS 430 from SS 450a, and the RACK index signal possibly be sent to BS 430 from RS 440c.In addition, in the embodiment that Figure 13 showed, RS 440c is designed in order to set relaying transmit timing device T again n(for example, T 2), transmit use again for the one or more parts between RS 440c and SS 450a.In this embodiment, work as T 2Expire or transmit when accomplishing the part of data again, RS 440c can transmit one or more ACK and/or RACK index signal to BS 430 after confirming buffer state.
In the sender figure of Figure 13, resource distribution can cooperate the explanation that Fig. 9 does and proceed.After accomplishing resource distribution, BS 430 can transmit packet data to destination node (for example SS 450a) via one or more intermediate nodes (for example, RS440a, RS 440b and RS 440c).In addition, BS 430 can store copy to a buffer of seeing packet data off.In the example of Figure 13, packet data be by 8 data packages (that is, Data (8)) form.
RS 440a can successfully receive Data (8), and the copy that stores packet data is to its buffer, and the transmission packet data is to RS 440b.Likewise, RS 440b can successfully receive Data (8), and the copy that stores packet data is to its buffer, and the transmission packet data is to RS 440c.Yet between the transmission period of RS440b to RS 440c, 2 packet datas possibly disturb owing to damage, mistake etc. and losing.Therefore, RS 440c possibly receive only 6 packet datas (that is, Data (6)), and can produce and transmit a RACK index signal (that is, RACK{6}) to BS 430, to reflect that 6 data are packaged into merit ground and are received by RS 440c.
RS 440c can transmit Data (6) to SS 450a, and the copy of storage transmission packet data is to its buffer.In an embodiment, when transferring to SS 450a with Data (6), RS 440c can set relaying transmit timing device T again 1As stated, supply relaying that each RS 440 uses again the transmit timing device possibly be set a numerical value, it is reflected in the total two-way time between RS 440 and the destination node (for example, SS 450a).In this, relaying is transmit timing device T again 1Possibly be set a numerical value, it is reflected in the total two-way time between RS 440c and the SS 450a.
At the example of Figure 13, Data (6) possibly lose between RS 440c and SS 450a.Therefore, SS 450a can't receive any data, and will can not prepare and/or transmit an ACK or NACK index signal.As above combine the explanation of Fig. 8, the relaying of RS 440c is transmit timing device T again 1To under the situation that does not receive ACK and/or NACK index signal, expire from SS 450a.In case relaying is transmit timing device T again 1Expire, RS 440c can produce an ACK index signal (that is, ACK (0)).The ACK index signal that is produced will reflect do not have the data packet can be by the fact of SS 450a approval.ACK that is produced and RACK index signal can transfer to RS 440b from RS 440c along the ul transmission path, and RS 440a is then to BS 430.In an embodiment, ACK and RACK index signal possibly produce and/or see off simultaneously.In another implemented example, the RACK index signal possibly produced and seen off in the packet data being received by RS 440c of success, but the ACK index signal maybe be at relaying transmit timing device T again 1Produced and seen off when expiring.
Except producing and transmitting the RACK index signal, RS 440c also can attempt being transmitted in again any packet data of losing between RS 440c and the SS 450a.For example, shown in figure 13, RS 440c can be transmitted in 6 packet datas losing between RS 440c and the SS 450a (that is, Data (6)) again.In an embodiment, RS 440c can begin one second relaying transmit timing device T again 2, begin first of packet data simultaneously and transfer to SS 450a again.Implement in the example in another, second relaying is transmit timing device T again 2Maybe with first relaying transmit timing device T again 1Begin simultaneously.Relaying is transmit timing device T again 2Possibly be configured to a numerical value, it is reflected in the total two-way time between RS 440c and the SS 450a.
In this example, SS 450a can receive only 6 wherein 5 of data packets of transmission again (that is, Data (5)).Therefore, SS 450a can produce and transmit an ACK index signal to RS 440c, with confirm 5 again the data packets (that is, ACK (5)) of transmission successfully be received.When RS 440c received ACK index signal (that is, ACK (5)), RS 440c can be transmitted in 1 packet data losing between RS 440c and the SS 450a (that is, Data (1)) again.When successfully receiving 1 Datagram (that is, Data (1)), SS 450a can produce an ACK index signal (that is, ACK (1)), and transmits the ACK index signal that produced to RS 440c.RS 440c can compare at present received ACK index signal information (that is; ACK (1)) with in the past received ACK index signal information (that is; ACK (5)); Obtaining an ACK index signal, the quantity of the data that it confirms successfully to be received by SS 450a and/or identification (that is, ACK (6)).In this example, the ACK index signal can be confirmed successfully 6 data packages that transmit again from RS 440c of being received by SS 450a.
RS 440c can continue to transmit again data, up to relaying transmit timing device T again 2Till expiring.In other embodiment, relaying transmit timing device again possibly transmit for each of packet data again and begins.In other embodiment, the relaying transmit timing device situation that possibly begin again comprises and all relevant transmission attempts again of one group of first transmission data.In either case, in case relaying transmit timing device T again 2Expire, RS 440c can be along the upstream transmission path, from RS 440c transferring ACK index signal (that is, ACK (6)) and/or transmitted the copy (that is, RACK (6)) of RACK index signal in the past to RS 440b, RS 440a is then to BS 430.
Though Figure 13 shows the transmission that the ACK index signal begins from SS 450a, SS 450a can transmit the ACK and/or the NACK index signal of any combination.Under a situation, error detection will be proceeded with correction, as stated.Again, though sender Figure 130 0 is presented in the single transmission path enforcement example of using three RS 440, people are contemplated to the number of the RS 440 in a transmission path can be greater or less than the number that is shown.In addition, though be not shown among Figure 13, between the transmission period of new data and at again between transmission period of data, also can use relaying transmit timing device again.
Figure 14 shows according to the ACK of an enforcement example of the present invention and the sender figure of RACK index signal.Shown in figure 14; BS 430 transmits 8 data packages to RS 440a; RS 440a successfully receives and transmits 8 data packages to RS 440b, and RS 440b successfully receives and transmit these 6 data packages to RS 440c, and RS 440c successfully receives and transmit these 6 data packages to SS450a.Yet SS 450a only successfully receives 3 data packages, and therefore, the ACK index signal that SS 450a is transmitted can inform that success receives 3 Datagrams.
In Figure 14, this ACK index signal that is produced by SS 450a possibly comprise 8 data areas, and SS 450a can confirm 3 data packages that success receives.Though the employed data area of the example of Figure 14 is single position, the figure place of these data areas or configuration and setting can be any.Shown in figure 14, SS 450 possibly produce the ACK index signal of " 11000100 ".SS 450a possibly be sent to RS 440c with the ACK index signal that is produced.
