Description
Technical field
The present invention relates to a kind of position mapping structure that in mobile communication system, is used to use the reception result of retransmission technique report bag, and a kind of method that is used to send/receive reception result.
Background technology
Usually, radio channel can cause the mistake, the interference between the user, noise of the transmission bag under the influence of multichannel decay etc.The solution of this problem comprises: forward error correction (FEC) scheme, reduce the wrong possibility that takes place by additionally sending redundant information therein; Automatic repetitive requests (ARQ) scheme, when wrong the generation, the repeating transmission of the bag that has made a mistake is requested therein; And mixed automatic retransmission request (HARQ) scheme, it is in conjunction with above two schemes.
In the ARQ scheme, whether the bag that receiver uses affirmation (ACK)/non-affirmation (NACK) signal to announce the transmitter reception is wrong.Ack signal confirms that to transmitter receiver has received corresponding bag.On the contrary, the NACK signal confirms that to transmitter receiver receives corresponding bag failure.If transmitter receives the NACK signal, then transmitter sends to receiver with corresponding bag.
Except reception result therein packet-by-packet to serve as the general ARQ scheme that is identified of basis, also have piece ARO scheme, the reception result of a plurality of therein transmission bags is identified as a whole by piece ARQ message.
Fig. 1 is based on supposition piece ARQ scheme and is applied to the diagrammatic sketch that example in per three bags illustrates the basic conception of general piece ARQ.With reference to Fig. 1, transmitter sends three bags in proper order, promptly wraps # 1, bag # 2 and bag #3.These three bags (bag # 1 is to wrapping #3) have identical destination address (DA), for example DA2.Each bag (bag # 1 is to wrapping #3) is equipped with serial number (SN) and fragment number (FN).SN represents to wrap the order that is sent out from the upper strata.When accidental demand, even the bag with identical SN also can be sent out by a plurality of bags.FN represents to send the order of a plurality of bags of cutting apart by transmission from bag with an identical SN.
SN and the SN of FN and the previous bag that receive and the FN of receiver by the bag that will receive compares and checks whether bag is received continuously and which bag is not received.In the following description, the bag on the SN level will be called as ' SN level bag ', and the bag of cutting apart from SN level bag will be called as ' fragmented packets '.When bag is not called as SN level bag or fragmented packets, when still this bag is called " bag " simply, this means to merge two types above-mentioned bag.
In three bags, first and second bags (bag # 1, bag #2) are the fragmented packets with identical SN (for example SN1) and different FN (for example Frag1, Frag2).Three guarantees (bag #3) are the SN level bags that has with first and second the different SN of SN (for example SN2) that wrap (bag # 1, bag #2).
In Fig. 1, suppose that receiver successfully receives first and three guarantees (bag # 1, bag #3) and receive second bag (bag #2) failure.
Receiver such as above-mentioned be that the configurations piece ACK message and the piece ACK message that will dispose send to transmitter with the reception result.This piece ACK message comprises head and payload.Destination address DA1 is recorded in the head.Destination address DA1 is the address of transmitter.The reception result of the bag that each receives is recorded in the payload.
Use above-mentioned hypothesis, ACK information as corresponding to first and the reception result of three guarantees (bag # 1, bag #3) be recorded, nack message is as being recorded corresponding to second bag (bag #2) reception result.The SN of corresponding bag and FN are recorded in the reception result together.
Transmitter receives piece ACK message.Transmitter successfully receives first and three guarantees (bag # 1, bag #3) and receive second bag (bag #2) failure by piece ACK message confirmation receiver.Thereafter, although do not show in Fig. 1, transmitter is retransmitted second bag (bag #2).
The reception result of the bag of all receptions therein is recorded in an above-mentioned scheme in the piece ACK message and can realizes in many ways.Yet in order to use the message with shortest length, the position mapping scheme is used.
Fig. 2 to Fig. 4 shows the example of the position mapping scheme that is used to confirm reception result.With reference to Fig. 2, piece ACK message comprises that piece ACK begins sequence field and position map field.The position map field is made up of N ACK report field.' N ' is with the corresponding value of maximum S and represents the maximum quantity of the sequence that can be identified.That is, ' N ' can be defined as can be by the allowed maximum amount of the SN level bag of a piece ACK Message Processing.
Being recorded in piece ACK with the SN level bag that mapping is handled in the corresponding message begins in the sequence field.From begin to record the sequence field SN at piece ACK the N that unwraps the beginning continuously each of reception result of bag be recorded in the map field on the throne.
Each ACK report field of forming the position map field be divided into corresponding (M * 8) the individual regional b0 of the quantity of the fragmented packets of at utmost being cut apart from a SN level bag, b1, b2 ..., b (n) ..., b (8 * M-1).Below, this regional b0, b1, b2 ..., b (n) ..., (8 * M-1) will be called as ' reception result information field ' to b.This is because reception result is packet-by-packet being that the basis is identified.Therefore, if reception result represents that with one then M eight bit byte is used to total reception result information field of a SN level bag, therefore a position map field has total length M * N eight bit byte.
For example, when SN=1 is recorded in piece ACK when beginning in the sequence field, the reception result with fragmented packets of SN=1 and FN=n-1 will be recorded among the reception result information field b (n) 210.If receiver successfully receives this fragmented packets, then ' 1 ' be recorded among the reception result information field b (n) 210.Otherwise,, then ' 0 ' be recorded among the reception result field b (n) 210 if receiver receives this fragmented packets failure.This is that expression receives successful designator bit based on hypothesis ' 1 ', and ' 0 ' is the designator bit that expression takes defeat.As another example, be recorded in piece ACK when beginning sequence field when ' 5 ', if fragmented packets has SN=6 and FN=3, then ' 1 ' be set to the 3rd of second eight bit byte.
Fig. 3 shows the above-mentioned general example when the system that is applied to based on IEEE 802.16 standards (802.16), and Fig. 2 shows the identical instances that ought be applied to based on the system of IEEE 802.11e standard (802.11e).
The piece ACK message that shows among Fig. 3 comprises connection ID field, ACK control field and a plurality of ACK MAP field.The ACK control field comprises the field that the quantity of the beginning field that is recorded in it of SN and ACKMAP (m) is recorded in it.ACK MAP field quantitatively equates with the quantity of ACKMAP (m).ACK MAP field have with Fig. 2 in the identical structure of structure of ACK report field.In Fig. 3, each of connection ID field, ACK control field and a plurality of ACK MAP fields is configured to 2 eight bit byte locations.Therefore, piece ACK message has total length ' (m+2) * 2 '.Usually, in 802.16, ' m ' is variable value, and the maximum quantity of fragmented packets is 16.
The piece ACK message that shows among Fig. 4 comprises that BA begins sequence control field and BA position map field.The information of the beginning sequence in the indication record map field on the throne is recorded in BA and begins in the sequence control field.BA position map field is made up of a plurality of ACK MAP fields.Each ACK MAP field have with Fig. 2 in the identical structure of structure of ACK report field.For example, in 802.11e, can carry out the ACK that is used for maximum 64 SN level bags simultaneously and handle, a SN level bag can be divided into 16 fragmented packets.Therefore, when each ACK MAP field was configured to 2 eight octet field, BA position map field must keep 128 octet-sized.
Summary of the invention
As mentioned above, if reception result uses the traditional bit mapping scheme to confirm, then produce the wasting of resources.That is, in the traditional bit mapping scheme, by considering that each SN level bag will be divided into the maximum segment bag and come the configuration bit mapping.Therefore, when wrapping corresponding reception result and be sent out with the SN level, the fragmented packets that this SN level bag is not divided into fragmented packets or is not divided into maximum quantity produces the reception result information field that is not used in the map field on the throne.This reception result information field can be called as resource unnecessary.

Embodiment
Below, preferred embodiment with reference to the accompanying drawings to describe the present invention.Though should note similar parts shown in the different accompanying drawings they represent by similar label.In addition, in the following description, will omit it when known function with when the detailed description of this structure of incorporating into may be blured theme of the present invention.
The present invention proposes to have the message of the structure that the size that makes the field (map field) that comprises according to the information of reception result when fully carrying out the inherent function of confirming reception result can be optimised.In addition, the present invention proposes to have the message of the structure of the size that reduces the position mapping greatly.In the following description, reduce the big or small position mapping configuration method of position mapping by the reception result of only reporting the bag that is not successfully received therein and will be proposed as first preferred embodiment.In addition, therein by reporting that the reception result based on the information that is provided by transmit leg comes the position mapping configuration method of the size of optimization position mapping will be proposed as second preferred embodiment.
Below, with reference to the accompanying drawings first preferred embodiment of the present invention is described in detail.
Can realize the first embodiment of the present invention based on two factors.
At first, PER (PER) in the general wireless data communication system of appointment on more rudimentary.The second, packet loss concentrates on particular moment rather than evenly distributes.
Consider this two factors, if vicious words, the quantity of erroneous packets may be very little, and mistake may be concentrated and occurs in particular moment.Therefore, receive the great majority bag and only receive some bag failures even take defeat also can hope to succeed.
If the ARQ scheme realizes like this: the reception result of the bag that only is not successfully received is identified, and then the amount of information according to the affirmation of reception result can be greatly diminished.Reduction according to the amount of information of the affirmation of reception result means that the size of position mapping reduces.
In the following detailed description, proposed to be used for only reporting piece ACK message with the corresponding reception result of fragmented packets that is not successfully received of the fragmented packets that sends from SN level bag.For this reason, be used to send make reception can by the maximum that piece ACK handles allow SN level bag each success or failure can confirmed designator field (after this, being called as ' SN level map field ') be redefined.In addition, the field (hereinafter referred to as ' ACK reports field ') that is used to send with the corresponding concrete reception result of the SN level bag that is not successfully received is redefined.Here, concrete reporting the result is to make each success or the failure of fragmented packets that reception sends from a SN level bag can confirmed designator.
In order to dispose this ACK message, transmit leg (having the side that receives bag) is to pursue SN is that the basis checks whether there is the bag that is not successfully received.Subsequently, for the bag that is not successfully received, transmit leg will ' take defeat ' to be provided with in SN level map field and give and the corresponding designator of the SN of the bag that is not successfully received.In contrast, for the bag that success receives, transmit leg in SN level map field, ' receiving successfully ' be provided with to the corresponding designator of SN of the bag that successfully receives.
Yet, when a plurality of fragmented packets with identical SN are received, can not only confirm the reception result of these fragmented packets by SN level map field.In this case, need make the grouping bag that is not successfully received can confirmed independent information.
Therefore, in the first embodiment of the present invention, create ACK report field individually according to the SN of the bag that is not successfully received.Be recorded with the corresponding designator of each fragmented packets, promptly designator is that the basis is recorded in the ACK report field to pursue FN.These designators represent to have identical SN fragmented packets the reception success or take defeat.By considering to dispose ACK report field from the maximum quantity of the fragmented packets of a SN level bag.
The piece ACK message that transmit leg will dispose like this sends to the recipient.
Recipient's (having the side that sends bag) confirms the reception success or the failure of each SN level bag by the designator of inspection record in the SN level map field of piece ACK message.When having the SN level bag that is not successfully received, the recipient checks with the SN level that is not successfully received and wraps corresponding ACK report field.The recipient is announced the fragmented packets that is not successfully received by the designator that is recorded in the ACK report field.
Fig. 5 shows the hierarchy bit mapping structure that proposes according to the present invention.
With reference to Fig. 5, the piece ACK message with hierarchy bit mapping structure comprises that piece ACK begins sequence field and position map field.The position map field is made up of SN level map field and wrong SN bag position map field.Mistake SN bag position map field comprises a plurality of ACK report fields (M * m ACK field).Here, ' m ' is corresponding to the quantity of zero (' 0 ') that be set to SN level map field.' M ' is the quantity of the SN level bag that is not successfully received.The SN of the SN level bag that the position mapping in the corresponding message is handled is recorded in piece ACK to begin in the sequence field.At this moment, a SN level bag can be defined as the SN level bag by piece ACK message authentication.Here, should notice that a SN level bag can not be interpreted as the SN level bag that first is not successfully received.
Expression is recorded in the SN level map field according to the designator (hereinafter referred to as ' the quick reference bit of SN ') of the reception result of each SN (receive successfully or fail).The length of SN level map field is by being allowed that the quantity of SN level bag determines by the maximum that piece ACK handles.That is, if can be allowed that the quantity of SN level bag is 8 * N by the maximum that piece ACK handles, then SN level map field has the length of N eight bit byte (8 * N position).Therefore, each of composition SN level map field is used as the quick reference bit of SN that distributes by SN.
Mistake SN bag position map field comprises ACK report field.Because the SN according to the bag that is not successfully received creates ACK report field individually, the quantity of the SN level bag that is successfully received so the quantity of ACK report field must be equal to nothing.Therefore, mistake SN bag position map field has M * m length in octets.Here, M eight bit byte, promptly the total length of ACK report field is a fixed value, so determine the total length (M * m eight bit byte) of wrong SN bag position map field by the quantity (m) of the SN level bag that is not successfully received.
For example, the quantity (m) of the SN level bag that is not successfully received is big more, and the total length (M * m eight bit byte) of mistake SN bag position map field is long more.In contrast, the quantity (m) of the SN level bag that is not successfully received is few more, and the total length (M * m eight bit byte) of mistake SN bag position map field is short more.The SN level bag that if there is no is not successfully received, then wrong SN level bag position map field can not exist.
ACK report field and be set between ' 0 ' the quick reference bit of SN mapping relations and can set up in many ways.In simple example, ACK report field is shone upon in proper order corresponding to the SN order of the quick reference bit of SN.
For example, if hypothesis piece ACK begin the value of sequence field be 5 and the value of SN level map field be 11101011, then two ACK report fields are present in the map field of mistake SN bag position.First of two ACK report fields becomes the position mapping of the SN level bag with SN=8, second position mapping that becomes the SN level bag with SN=10.In addition, can adopting therein, designator is assigned to the scheme that ACK reports field.
The designator that is used for reporting the reception result of each fragmented packets is recorded in ACK report field.Therefore, corresponding to a SN level bag (M * 8) can divided fragmented packets the designator of maximum quantity exist.This be because with by fragmented packets be that reception result is confirmed on the basis.In Fig. 5, by ' b0, b1, b2 ..., b (n) ..., b (8 * M-1) ' come specify indicators.For example, if designator represents that with one then an ACK report field has M length in octets.
Below, will the example that actual disposition has the piece ACK message of structure as shown in Figure 5 be described.
When the grouping bag of cutting apart when all SN level bags from having SN=n+1 was successfully received, the quick reference bit b of (n+1) SN (n) in the SN level map field was set to ' 1 '.Yet even when a fragmented packets is not successfully received, the quick reference bit b of (n+1) SN (n) in the SN level map field also is set to ' 0 '.That is,, also be set to " taking defeat " with the corresponding reference bit fast of the SN of the fragmented packets that is not successfully received even when a fragmented packets is not successfully received.In this case, must provide and make the fragmented packets that is not successfully received can confirmed independent information.
If supposing the fragmented packets with SN=n+1 and FN=n+1 is not successfully received, the quick reference bit of (n+1) SN then, be that b (n) in the SN level map field is set to ' 0 ', the ACK report field (below be called as m ACK report field) that will be mapped to b (n) is assigned to a SN bag position map field.Subsequently, represent that the position that takes defeat is set to (n+1) designator b (n) in the m ACK report field.At this moment, expression receives successful position and is set to removing in the residue designator of (n+1) designator b (n) in the m ACK report field.As an example, ' 0 ' is used as the designator that expression takes defeat, and ' 1 ' is used as expression receives successful designator.
Fig. 6 and Fig. 7 show the example of the message that is used to report reception result when aforesaid the present invention is applied to system based on IEEE 802.11n standard (802.11n).The example that shows among Fig. 6 and Fig. 7 is distinguished from each other by the quantity of the bag that is not successfully received.That is, if the quantity of the MAC service data unit (MSDU) that is not successfully received does not reach threshold value (as 12), then the message structure that shows among Fig. 6 is used.Yet if the quantity of the MSDU that is not successfully received is equal to or greater than threshold value (as 12), the message structure that shows among Fig. 7 is used.
With reference to Fig. 6, piece ACK message comprises that BA control field, BA begin the position map field of sequence control field and BA mistake MSDU.
The BA control field has 2 length in octets.The BA control field comprises position map field and the TID field of BA MSDU.The position map field of BA MSDU is made up of the reception success that is used to represent each SN level bag or the quick reference bit of failure.The position map field of BA MSDU is the zone that also is not used in existing 802.11, and is reused for the present invention.Because the quantity of the MSDU that Fig. 6 hypothesis is not successfully received is lower than 12 situation, so the position map field of BA MSDU is configured with 12 sizes.
In addition, any in the BA control field can be assigned to message indicator.As an example, first in the BA control field can be assigned to message indicator.Message indicator Indication message type.In Fig. 6, ' 1 ' is used as message indicator.
The SN of the SN level bag that the position mapping in the corresponding message is handled is recorded in BA to begin in the sequence control field.The one SN level bag is the bag that the quilt from the bag of the continuous transmission that is used for piece ACK at first sends, and should notice that a SN level bag is not first SN level bag that is not successfully received.
The position map field of BA mistake MSDU is made up of a plurality of ACK MAP fields that quantitatively are no more than 11.The position map field of BA mistake MSDU has with the above wrong SN that describes with reference to Fig. 5 wraps the identical 26S Proteasome Structure and Function of 26S Proteasome Structure and Function of position map field, therefore will omit the detailed description of the position map field of BA mistake MSDU.
With reference to Fig. 7, piece ACK message comprises that BA control field, BA begin the position map field of sequence control field, BAMSDU and the position map field of BA mistake MSDU.
Any one in the BA control field all is assigned to message indicator.As an example, first of the BA control field can be assigned to message indicator.In Fig. 7, ' 0 ' is used as message indicator.In addition, the another one in the BA control field is assigned to successfully designator.This success designator indicates all bags (64 MSDU of hypothesis in Fig. 7) to be successfully received (being specified by ' A ' among the figure).When all SN level bags were successfully received, successful designator was set to ' 1 '.Yet even when a SN level bag is not successfully received, successful designator also is set to ' 0 '.If successful designator is set to ' 1 ', then do not need position map field and the BA erroneous packets position map field of BA MSDU.
The position map field of BA MSDU carry out with the BA control field that is present in as shown in Figure 6 in BA MSDU position map field function identical functions, so will omit detailed description.Only difference is that the position map field of the BA MSDU among Fig. 7 has 64 (8 eight bit byte) size to represent the reception success or the failure of 64 bags between the position map field of two BA MSDU.
The position map field of BA mistake MSDU is by forming with the corresponding ACK MAP of the quantity of the bag that is not successfully received field.The position map field of BA mistake MSDU has with the above wrong SN that describes with reference to Fig. 5 wraps the identical 26S Proteasome Structure and Function of 26S Proteasome Structure and Function of position map field, therefore, also will omit the detailed description to the position map field of BA mistake MSDU.
Below, with reference to the accompanying drawings second preferred embodiment of the present invention is described in detail.
Second embodiment of the present invention hypothesis is used for the system that from the transmit leg to recipient piece ACK claim frame sent with the continuous data frame.Piece ACK claim frame comprises the required information of reception result that sends each Frame.Piece ACK claim frame can be sent out before or after the transmission of Frame.Certainly, can send piece ACK claim frame and Frame simultaneously.
Recipient's receiving data frames and piece ACK claim frame.The recipient serves as that position mapping allocation plan is determined on the basis with the information that receives by piece ACK claim frame, and subsequently according to the position mapping allocation plan configuration bit mapping of determining, thereby the position mapping comprises the reception result of Frame.Confirm the position mapping by piece ACK frame to transmit leg.
In the second embodiment of the present invention, be sent out by piece ACK claim frame about " quantity (m) of the SN level bag that will be sent continuously " and the information of " maximum quantity of fragmented packets (n) ".Usually, if necessary, the SN level bag that has been divided into a plurality of fragmented packets is sent out.The maximum quantity of fragmented packets (n) is the maximum quantity of the fragmented packets that can be packed by the SN level that will be sent out.
In the following description, be used for sending the operation of piece ACK claim frame and the structure of piece ACK claim frame with going through at transmit leg.In addition, be used for the recipient by piece ACK frame report based on by the operation of the reception result of fragmented packets and the structure of piece ACK frame going through.
And, in example of the present invention, given the regularly operation of execution at random with discussing when the quantity (m) of the bag that will be sent continuously and the maximum quantity of fragmented packets.
Below, the operation to transmit leg and recipient according to a preferred embodiment of the invention is described in detail.
Fig. 8 shows the control flow of the operation of explaining transmit leg according to a preferred embodiment of the invention.
With reference to Fig. 8, in step 810, the quantity (m) of definite bag that will be sent out.The determining of ' m ' is subjected to the number affects of the SN level bag that will be sent continuously.Each SN level bag can be split into a plurality of fragmented packets and send.In step 812, the maximum quantity of fragmented packets is determined, and in other words, the cutting state of each SN level bag is proved.That is, the quantity of the fragmented packets of cutting apart from each SN level bag is detected, and is determined from the divided SN level of its maximum segment bag bag.The quantity of the fragmented packets of cutting apart from the SN level bag of finding is confirmed as the maximum quantity (n) of fragmented packets.
In step 814, piece ACK request (BAR) frame is disposed like this: above definite ' m ' and ' n ' are included in the BAR frame.At this moment, the piece ACK that the SN of the SN level bag that is sent out is recorded in the BAR frame begins in the sequence control field.Transmit leg sends to the recipient with the BAR frame.Figure 10 will discuss the structure of BAR frame.
