Abstract
Synchronous adaptive HARQ is utilized to mitigate resource fragmentation. Bitmaps are utilized instead of scheduling uplink grants for retransmission. The location of one or more resource blocks can be changed if there is a release of resources in a location of a corresponding resource block. Changing the location of the one or more resource blocks can group the resource blocks toward a first endof a spectrum. The bitmap can include a retransmission offset and a signal that indicates a direction with respect to the retransmission offset. The direction can be a positive direction or a negativedirection.

Provide each scheme according to the system that can comprise a plurality of equipment, assembly, module etc.Be to be understood that and recognize that each system can also comprise supplementary equipment therefore, assembly, module etc. and/or can not comprise in conjunction with the accompanying drawings all devices discussed, assembly, module etc.In addition, can also use the combination of these methods.
With reference now to Fig. 1,, it shows the multi-address radio communication system 100 according to one or more schemes.Wireless communication system 100 can comprise the one or more base stations with one or more user equipment contact.Each base station provides covering for a plurality of sectors.Three sector base stations 102 comprise a plurality of antenna groups, and antenna groups comprise antenna 104 and 106, and another antenna groups comprise antenna 108 and 110, and the 3rd antenna groups comprise antenna 112 and 114.According to this figure, only each antenna group is shown two antennas, still, each antenna group can utilize more or less antenna.Mobile device 116 is communicated by letter with 114 with antenna 112, wherein antenna 112 and 114 on forward link 120 to mobile device 116 transmission information, and on reverse link 118 from mobile device 116 reception information.Forward link (or down link) is meant the communication link from the base station to the mobile device, and reverse link (or up link) is meant the communication link from the mobile device to the base station.Mobile device 122 is communicated by letter with 106 with antenna 104, wherein antenna 104 and 106 on forward link 126 to mobile device 122 transmission information, and on reverse link 124 from mobile device 122 reception information.
Specify the zone that is used to communicate by letter to be called the sector of base station 102 each antenna group and/or antenna.In one or more schemes, in the zone that each antenna group is designed in the sector or base station 102 is covered with mobile device communication.The base station can be the fixing station that is used for terminal communication.
Usually, when the air interface scheduling of quadrature accessed terminal more than two, synchronous non-self-adapting HARQ can cause the resource segmentation.This resource segmentation can occur on up link and the both downlink.On down link, can solve the resource segmentation with the flexible scheduling format of licenses, cost is the expense of downlink control channel.But on up link, because the single-carrier property of waveform can not solve the resource segmentation problem effectively with synchronous non-self-adapting HARQ.Therefore, as described below, disclosed scheme is utilized synchronous self-adapting to mix automatic repeat requests (HARQ) to alleviate mis-behave.According to disclosed one or more schemes, utilize the bit mapping to replace scheduling uplink to permit and retransmit (ReTx).
Forward Fig. 2 now to, it shows the system 200 that utilizes synchronous self-adapting HARQ to come operation dispatching and comprises radio communication device 202 in wireless communications environment, and radio communication device 202 is depicted as by channel and sends data.Though radio communication device 202 is described as sending data, but radio communication device 202 can also (for example receive data by channel, radio communication device 202 can transmit and receive data simultaneously, radio communication device 202 can transmit and receive data at different time, and perhaps both of these case combines or the like.) radio communication device 202 can be for example base station (for example, base station 102 of Fig. 1 etc.), access terminal (Fig. 1 access terminal 116, Fig. 1 access terminal 122 etc.) etc.
Transmit control channel from the base station, control channel provides permission, for example access permission.Control channel can be followed down-link data channel or uplink data channel.Access terminal and on up link, to transmit, unless the base station provides the permission that accesses terminal and transmit on this up link.On down link, accessing terminal at first decodes to control channel is used for the data that this accesses terminal so that determine whether to exist.If exist and be used for the data that this accesses terminal, access terminal by this so the remainder of data channel is decoded.
Utilizing HARQ to carry out error control, and use HARQ when transmitter continues to send similar " transmission block ", should " transmission block " be the grouping of coding wherein.This transmission block can be used as the different redundancy version that has different coded-bits but relate to identical information bit and sends.Because down link is asynchronous, so at least on down link, the time durations that sends that accesses terminal is definite by network (for example, base station).Up link is synchronous, but network (for example, the base station) determine to access terminal and be used for sending the resource of data, this can produce too much expense in some cases.
For example, be 0 to 25 with resource number, and access terminal and on resource 20 to 25, send.Other accesses terminal and can send on resource 0 to 19, and therefore, will reserve to be accessed terminal by other corresponding to the bit position in the control channel of bit 0 to 19 to send on these resources.If in any one of resource 0 to 25 or all have " 0 " on the resource, this indication transmission is successful and distributes to accessing terminal of this specific resources and wait for that new channel is to send thereon.If from 0 to 25 resource all is " 1 ", indicate the neither one transmission to be successful and to access terminal and retransmit so.
Continue this example, if resource all is " 0 " (perhaps its subclass is set to " 0 ") from 0 to 19, this indicates assigned the accessing terminal of those resources not utilize these resources (for example, transmission is successful).Therefore, according to one or more disclosed schemes, being assigned accessing terminal of resource 20 to 25 can not retransmit on resource 20 to 25, but can retransmit on the one or more resources in the resource that is discharged (being set to " 0 ") 0 to 19.Therefore take the current resource that is not used.Like this, access terminal and to determine to send once more the position of (HARQ).A selection is to transmit on identical resource (20 to 25), but this can cause the resource of segmentation, can alleviate the resource of segmentation by taking the resource of not utilizing.
The problem that transmission on same asset (20 to 25 in the above example) is associated is that the space is by segmentation.This be because, if exist 10 access terminal and 5 stop 5 and do not stop, then the resource that takies has been become random distribution with the resource that will not take.This has limited scheduler, because this space need is filled in scheduling, and because this is distributed in the resource is continuous (being single carrier waveform on its up link), may have empty space so, and other accesses terminal may need this space etc.
Therefore, system 200 can be by moving this resource with specific direction forward or backwards so that the resource compactness alleviates empty spatial division.Then, can use skew, this skew joins compact Resource Block in the frequency spectrum.Therefore, system 200 uses a kind of mechanism and makes the resource compactness, and the ability of using skew is provided and can carrying out frequency hopping etc. thereafter.
Resource place adjuster 204 determines whether to receive " 0 " or " 1 " based on the place of corresponding Resource Block in the bit mapping for what whether change the place.The termination that " 0 " can indicate the HARQ of given transmission block to retransmit.Resource place adjuster 204 can discharge and need based on " 0 " deduction resource that receives can be by other utilization that accesses terminal." 1 " can indicate continuation HARQ to retransmit and resource is not released.According to some schemes, " 0 " can indicate sure affirmation (ACK) and " 1 " can indicate negative affirmation (NACK).
According to the place of Resource Block, bit mapping creator 208 can be created bit and shine upon the place of representing correspondence.In the bit mapping, can indicate the place that is changed by signal, this signal can be a bit.The direction that this signal (or bit) can indicating positions changes, it can be forward or backwards.Transmitter 210 can change into and send bit mapping rather than up link permission.If the position does not change, can not create and/or send the bit mapping so.The termination that the situation of no bit mapping can indicate HARQ to retransmit.
In order to understand disclosed scheme fully, Fig. 3 shows the resource segmentation problem 300 that can be alleviated according to disclosed scheme.Each piece indication least resource piece of 302 marks.Transverse axis 304 express times and the longitudinal axis 306 expression frequencies.This case representation 4 access terminal and 3 transmission.Each transmission is marked as 0 to 5 and indicate by 308,310 and 312.Represent the resource that each institute that accesses terminal utilizes and is assigned to different shades, wherein a kind of shade is used for one and accesses terminal.
Shade during the first transmission set (0 to 5) of 308 marks (each accesses terminal and uses different shades) the new transmission of indication scheduling.As shown in the figure, 314 places illustrate, and the resource allocation of first end of frequency spectrum accesses terminal to first.316 places illustrate and resource allocation are accessed terminal to second and 318 places illustrate and give the 3rd to access terminal resource allocation.320 places illustrate and give the 4th to access terminal the resource of second end of frequency spectrum.
On up link, as transmit shown in 310 and 312, have the fragment of resource.For example, first access terminal on the ul transmissions 310 on Resource Block 0,1 and 2 and on Resource Block 3,4 and 5, do not transmit.During ul transmissions 312, first accesses terminal in Resource Block 0 and 1 and do not transmit on Resource Block 2,3,4 and 5.Second accesses terminal is transmitting on Resource Block 1,2,3 and 4 (and not at Resource Block 0 or 5) during the ul transmissions 310, and is transmitting on Resource Block 1,2,3 and 4 (but not at Resource Block 0 or 5) during the ul transmissions 312.The 3rd accesses terminal is transmitting on 0 Resource Block 0,1 and 2 (but not at Resource Block 3,4 or 5) during the ul transmissions 310, and is transmitting on Resource Block 2 (and not at Resource Block 0,1,3,4 or 5) during the ul transmissions 312.In this example, the 4th accesses terminal is transmitting on Resource Block 0,1,2 or 3 (and not at Resource Block 4 or 5) during the ul transmissions 310, and is transmitting on Resource Block 0 and 2 (and not at Resource Block 1,3,4 or 5) during the ul transmissions 312.Therefore, be not access in the Resource Block of terminal utilization or the fragment that resource causes uplink resource, and scheduler can not be dispatched on entire available bandwidth and newly accesses terminal.
Can alleviate fragment problems by realizing synchronous self-adapting HRAQ, synchronous self-adapting HRAQ is similar to asynchronous adaptive H RAQ.Asynchronous adaptive H RAQ means each transmission of scheduling.This solution does not constitute significant expense on down link, because the quantity of the transmission of each transmission block is generally less.Its prerequisite is link circuit self-adapting and does not almost have Power Limitation.
But Power Limitation is being arranged the transmission of larger amt on up link, so that needed energy per bit of each information bit and noise plus interference ratio (Eb/Nt) are minimized.The Eb/Nt of needed each information bit minimizes the minimum interference that causes other sub-district, and this helps cell edge to access terminal and therefore can cover and maximum capacity.Therefore, on up link, dispatch the of a high price of each transmission.
Dispatch each transmission also as acknowledgement channel.Receive the scheduling grant of re-transmission if access terminal, the transmission block that the affirmation (NACK) that this permission is interpreted as negating and retransmitting of accessing terminal is so dispatched predetermined or the redundancy version that sends by signal.Otherwise if do not receive scheduling grant, then (ACK) confirmed in supposition.The scheduling of each transmission is flexible, and at this moment because it allows the self adaptation of modulation and coding and resource block size, but this elasticity is unnecessary in most of situation.
Disclosed scheme is better than above-mentioned basic technical scheme, and can alleviate the downlink control channel expense.According to some schemes, frequency hopping is possible and is controlled, for example, is subjected to the control of scheduler.In one or more disclosed schemes, Resource Block is distributed in the bit mapping.
Fig. 4 shows the synchronous self-adapting HRAQ scheme of minimal overhead by utilizing the bit mapping.In order to alleviate expense and to attempt to prevent the resource segmentation, one or more disclosed schemes are utilized synchronous self-adapting HRAQ scheme.Shown in 400, radio communication device can change the place of the resource of distribution.According to some schemes, can also adjust bandwidth.
As shown in the figure, each Resource Block (one of them is labeled as 402) is assigned to the position in the Resource Block bit mapping 404.Resource Block bit mapping 404 can be used for scheduling and retransmits.According to some schemes, bit mapping 404 can also be as acknowledgement channel.
If bit is shone upon 402 after the bit mapping of the correspondence that comprises Resource Block (access terminal and send data on this Resource Block) decoded and is configured accessing terminal, can sum up the behavior that accesses terminal according to three kinds of different situations so, now with described.First kind of situation is to access terminal not receive the bit mapping, and this indication HARQ retransmits and may stop.
According to some schemes, if do not receive bit mapping, this indication HARQ retransmits and may stop, and the check up link is permitted and determined whether transmit new data or identical data.Can in the subframe identical, permit perhaps receiving uplink permission in different subframes by receiving uplink with the indication that receives HARQ re-transmission termination.If new data indicator (NDI) bit in the up link permission has been carried out set, then its indication should send new data.If new data indicator (NDI) bit in the up link permission is not set, then its indication retransmits identical data with different forms.
Second kind of situation is to access terminal to receive " 0 " in the bit mapping in the place that do not receive uplink scheduling permission and corresponding Resource Block.The termination that this indicates the HARQ of given transmission block to retransmit.In this case, this resource is discharged (for example, resource discharge), and the words that need other access terminal and can utilize this resource.
The third situation is to access terminal not receive uplink scheduling permission and receive " 1 " in the bit mapping in the place of corresponding Resource Block.This indication continues HARQ and retransmits.In this case, accessing terminal retransmits corresponding transmission block, wherein, shines upon computational resource piece place according to bit shown in Figure 4.The Resource Block that will be used for retransmitting carries out polymerization towards the resource at an edge of bandwidth or other grouping of this bit mapping.
In more detail, in Fig. 4, the transverse axis instruction time 406 and longitudinal axis indication frequency 408 during transmission 410.Also show two ul transmissions 412 and 414.Be similar to the resource that Fig. 3 distributes, resource 0 to 5 distributed to 4 access terminal, shown in 416,418,420 and 422.
For the fragment that takes place on the up link among the figure before alleviating, the place of distributing to one or more resources that access terminal is adjusted.It should be noted that, hereinafter only be for illustrative purpose and other configuration can be arranged.As shown in the figure, during transmission 412, first access terminal and on Resource Block 0,1 and 2, transmit in up link.Because resource 3,4 and 5 is idle (not by first access terminal use), can utilize these resources so another accesses terminal.During ul transmissions 414, first accesses terminal transmits on up link during Resource Block 0 and 1.Resource Block 2,3,4 and 5 is idle, and can be by another utilization that accesses terminal.Second accesses terminal in the resource 1 of distributing to it during first ul transmissions 412 and 2 and distributed in the past on first resource that accesses terminal 3 and 4 and transmit.During ul transmissions 414, second accesses terminal in the resource 1 of distributing to it and 2 and distributed in the past on first resource that accesses terminal 2,3 and 4 and transmit.Similarly, the 3rd access terminal during the ul transmissions 412 in its resource 1 and 2 and distributed in the past on second resource that accesses terminal 0 and transmit.During ul transmissions 414, the 3rd accesses terminal transmits on the resource 2 of distributing to it.At last, the 4th access terminal during the ul transmissions 412 in the resource 1 of distributing to it and 2 and distributed to the 3rd resource that accesses terminal 0 in the past and distributed in the past on second resource that accesses terminal 3 and transmit.During ul transmissions 414, the 4th accesses terminal in the resource 2 of distributing to it and distributed in the past on second resource that accesses terminal 0 transmits.
As shown in Figure 4, resource is towards bottom (for example, the right-hand member) polymerization of frequency spectrum, yet resource is polymerization otherwise.Show interweaving of above-mentioned transmission 424.According to some schemes, can transmit control channel before at two Transmission Time Intervals (TTI) of traffic channel transmission.
Fig. 5 shows the bit mapping format 500 that can utilize with disclosed scheme.The initial Resource Block that will be used for the re-transmission group is called ReTx skew 502, and it can be (one of them end of bandwidth) of being scheduled to or send by signal in bit mapping itself.In the figure, Resource Block (RB) RNTI 504 is used for indication bit mapping 500.As an example, show 25 Resource Block (mark not 0 to 24), and disclosed scheme can be utilized more or less Resource Block.ReTx skew 502 can be about 5 bits, but according to some schemes, it can be more than (or being less than) 5 bits.According to some schemes, radio communication device can come direction of transfer by signal, is referred to as " D " bit 506.These bit 506 indications are according to 502 pairs of directions that Resource Block shines upon of ReTx skew.Bit 506 can be indicated in the other direction or positive direction.
Wipe resource segmentation possible under the situation of speed in order to alleviate at height on this channel, radio communication device can be carried out energy measuring to estimate whether have some resources not to be used on scheduled resources.
According to some schemes, can use the Resource Block bit to shine upon and replace downlink acknowledgment channel (DLACKCH).But, accessing terminal and still can read DLACKCH, DLACKCH is used to determine whether successfully transmitted transmission block.
Except the termination that indication HARQ retransmits, " 0 " in the bit mapping also indicates sure affirmation (ACK)." 1 " in the bit mapping can indicate negative affirmation (NACK).If do not receive the bit mapping, this can indicate negative affirmation (NACK) so, and can retransmit identical data when subsequently receiving to access terminal when up link is permitted.According to some schemes, do not receive the potential positive acknowledgement of bit mapping indication, can transmit new transmission block when receiving to access terminal when new up link is permitted.
According to some schemes, do not receive bit mapping indication HARQ and retransmit and to stop, and the permission of check up link is to determine whether transmitting new data or identical data.Can receiving uplink permission or receiving uplink permission in different subframes in the same sub of the indication that receives the termination that HARQ retransmits.According to some schemes, up link permission indication should send identical data with different-format.
Access terminal and to dispose transmission maximum times at given transmission block.Successfully do not decoded if reached this restriction and transmission block, network has two selections at least so, promptly confirms this transmission block in the negative or confirms this transmission block for certain, will discuss to it now.
Can be changed to " 1 " by the bit mapping position with correspondence utilizes and confirms this transmission block in the negative.In this case, continue to use scheduled resources by sending new transmission block with identical modulation and coding, accessing terminal.Can control (RLC) according to radio link and carry out the mistake recovery.Continue identical transmission block if access terminal, can utilize the MAC layer to retransmit so.
Can be changed to " 0 " by the bit mapping position with correspondence utilizes and confirms this transmission block for certain.In this case, access terminal and to stop to transmit data and wait for and transmitting again after the new scheduling grant.Recover for mistake, accessing terminal can be according to RLC in this scheduling grant and/or new data indicator (NDI).
If the maximum times of regulation transmission can not realize the dynamic network control to retransmission number so.In fact, radio communication device can decide to access terminal when to abandon retransmitting current transmission block by establish reset in the bit mapping.
Mutual with uplink scheduling permission will be discussed now.Uplink scheduling permission completely can be represented the transmission of new transmission block or the re-transmission of previous transmission block.For this purpose, can utilize new data indicator (NDI) bit of a part of permitting as up link.According to some schemes,, can indicate then that it always sends new data when receiving the up link permission when accessing terminal if do not utilize NDI.
If receive uplink scheduling permission completely, transmit data in the position of the indication in this uplink scheduling permission that then accesses terminal.Receive up link permission if access terminal, if set the NDI bit, the new transmission block of transmission then accesses terminal.Receive up link permission if access terminal, if set NDI bit not then accesses terminal and continues the re-transmission of current transmission block.
When having " 0 " in the bit mapping (release of indexed resource), radio communication device should send the up link permission routinely.If indication " 1 " in bit mapping, then radio communication device Ying Zaiyu accesses terminal to dispatch in the identical resource of the resource only using bit to shine upon to calculate and accesses terminal.According to some schemes, can utilize uplink scheduling to permit to indicate whether to transmit new transmission block and modulation and coding whether to change.
According to some schemes,, can provide lasting resource block assignments to accessing terminal in order to solve cell edge problem or control channel overhead issues to the service of delay-sensitive.In order to alleviate resource fragmentation, this distribution should be limited in the edge of bandwidth.At least leave several signalling bandwidth options to continuing distribution.One of them of these options will be described now.
Suppose to carry out the polymerization that retransmits, then will distribute the resource of semi-static lasting distribution to be mapped to top (right side) portion that bit shines upon towards the base of bandwidth and bit mapping.But this only is the example that resource is shone upon.
If the position at the Resource Block of correspondence in bit mapping receives " 0 ", the termination that it indicates the HARQ of given transmission block to retransmit.If the position at the Resource Block of correspondence in bit mapping receives " 1 ", its indication HARQ retransmits and continues.If do not receive the bit mapping, the transmission ending of this indication transmission block.
According to some schemes,, can near the centre of this bandwidth, use the frequency hopping of every Transmission Time Interval (TTI) in order to realize some diversity.This frequency hopping is applied to whole Resource Block, and can comprise that the reflection between bit mapping and the Resource Block penetrates.
According to some schemes, can utilize configuration with frequency selective scheduling.Fig. 6 shows division of resources 600 and bit mapping format 602, and it is used for the division of resources of frequency diversity scheduling and frequency selective scheduling.What illustrate is two sub-bit mappings, promptly sub-bit mapping 1 (604) and sub-bit mappings 2 (606).In the sub-bit mapping 604 and 606 each comprises paired frequency diversity scheduling Resource Block 608 and 610 and frequency selective scheduling Resource Block 612 and 614.Be physical uplink control channel (PUCCH) shown in 616 and 618.
Network can dividing frequency selectivity Scheduling Block 612 and 614 and frequency diversity scheduling piece 608 and 610 between resource.Can on broadcast channel, announce this and cut apart, and whole in the geographic area of sub-district or base station access terminal and can know this and cut apart.
Directional bit D and ReTx skew with correspondence appends in the sub-bit mapping 604 and 606 potentially.As shown in Figure 4, resource allocation application each in sub-bit mapping 604 and 606.Can handle frequency selective scheduling 612 and 614 with the similar mode of continuous dispatching.Therefore, if on the position of the Resource Block of correspondence, receive " 0 ", the termination that this indication HARQ retransmits in the bit mapping.If in the position of the Resource Block of correspondence, received " 1 " in the bit mapping, the re-transmission of this indication scheduling (for example, HARQ retransmit continuation).Under the situation of the re-transmission of dispatching, access terminal and use identical resource to retransmit corresponding transmission block once more.If do not receive the bit mapping, this can indicate the termination of the transmission of transmission block.
According to some schemes, when having massive band width, can distribute a plurality of bit mappings to accessing terminal.Can cut apart resource statically, be similar to the situation of frequency selective scheduling, accessing terminal in this case only needs to decode the individual bit mapping.According to some schemes, the bit mapping that may need correctly to decode all of accessing terminal, and come computational resource allocation based on the content that the bit of the resource under the resource that is mapped to it shines upon.
In some versions, there is time (continuing) operation of control channel that is used for internet voice protocol (VoIP).On accessing terminal, under the situation of the inferior pattern (less mode) of control channel, permit that with lasting up link dispatching first transmits.Resource allocation is accessed terminal to this, access terminal and to utilize this resource to transmit first redundancy version of each transmission block.Usually, in an example, the resource that is used for first transmission can be periodic, about 20ms at interval.Can shine upon and dispatch re-transmission with being similar to the bit shown in Fig. 5.
Therefore, the control channel that is used for VoIP different being between time pattern scheduling and the dynamic dispatching: scheduler should not guaranteed to retransmit and conflicts mutually with the resource of distributing to initial transmission in the previous case.Under the situation of dynamic dispatching, after retransmitting, dispatch first transmission.
Can utilize the described bit mapping method that is used for the scheduling uplink transmission to come schedule downlink business in a similar fashion.But when schedule downlink was professional, downlink HARQ should be synchronous self-adapting rather than asynchronous adaptive.
One or more adaptive bandwidths of can supporting in the various schemes transmit.When scheduling accesses terminal on more than single Resource Block, a plurality of bits place in this bit mapping can be mapped to given accessing terminal.In this case, some use bits to shine upon the bandwidth self-adaption that retransmits might the number of delivering a letter.For example, on four Resource Block, dispatch and access terminal.Three Resource Block NACK's and a Resource Block ACK's.Three Resource Block can transmit overall Negative Acknowledgement (because only having the Resource Block of an ACK) with signal.But, access terminal and will on three Resource Block rather than four Resource Block, retransmit.
To give more than a resource block assignments under the situation about accessing terminal, exist intrinsic redundant and be possible in the bit mapping the bandwidth adjustment of some forms of retransmitting.The combination of " 0 " and " 1 " can be indicated increase rather than the minimizing or the identical bandwidth of the bandwidth that is used to retransmit.But, such coding should be all access terminal known.
Fig. 7 shows the bit mapping format 700 with the optional skew that is used for the skew of persistent resources piece.Shown bit mapping 700 is used for the 5MHz system, but disclosed scheme is not limited to the 5MHz system.
Less bandwidth can have less bit mapping accordingly.Bigger bandwidth can be utilized bigger bit mapping or a plurality of bit mappings of can decoding that access terminal.Can also big bandwidth division be become independently frequency band (one of each bit mapping) semi-staticly, and allow between them, to exist some fragments.
According to some schemes, can utilize at least two kinds of methods that are used for up link internet voice protocol (VoIP).These methods comprise synchronous self-adapting and synchronized packets.Synchronous self-adapting comprises first transmission of non-scheduling and the re-transmission of scheduling.Synchronized packets comprises public L1/L2 message, and this message can allow self adaptation.
According to some schemes, utilize synchronous self-adapting to carry out first transmission and the re-transmission of scheduling fully of non-scheduling with packet scheduling.For the re-transmission of scheduling fully, can shine upon with the Resource Block bit and dispatch grouping, and/or can have independent up link permission.Packet scheduling with the mapping of Resource Block bit can alleviate signaling consumption, and can be used as the associating acknowledgement channel.Independently DL ACKCH is inessential.Optional perfect elasticity when independent up link permission can be included in Resources allocation, and can rewrite the mapping of Resource Block bit.
For the lasting distribution that is used for first transmission,, do not dispatch first transmission according to some schemes.Radio communication device accesses terminal to VoIP provides periodic continuing to distribute.
According to some schemes, for ul transmissions that scheduling is provided fully and in order to keep downlink overhead in certain limit, can utilize the mapping of Resource Block bit, wherein, each least resource piece is mapped to position in the mapping of Resource Block bit.The mapping of Resource Block bit can be considered as being used to dispatch the L1/L2 control channel of a group of access terminal.Except scheduling retransmitted, the mapping of Resource Block bit can also be as acknowledgement channel, and independently DLACKCH is inessential.
Under the situation that does not have conventionally line link permission, access terminal and explain the bit mapping in the following manner.Receive the termination (sure ACK) of " 0 " indication to the HARQ re-transmission of given transmission block.Receive the continuation (negative ACK) of " 1 " indication to the HARQ re-transmission of given transmission block.Access terminal and not receive the termination that the bit mapping is interpreted as the HARQ re-transmission.It can be interpreted as the ACK that negates.Access terminal and to repeat the HARQ process to this transmission block.Then, access terminal can amount of the claim outer resource to prevent to produce formation.
Under the situation that does not have the permission of line link conventionally, after the moment, t transmitted, start from Resource Block place k, accessing terminal is used to t+n the position of the scheduling resource piece that retransmits constantly, is designated as RB (t+n) and is calculated as:
Wherein, (t, i) indexed resource piece place i is designated as RB (t)=i in the value of the bit mapping of the transmission of the correspondence of moment t to Bitmap.Radio communication device B can change the position of the resource of distribution with the RetRxoffset field.
Needing under the flexible completely situation of uplink scheduling, radio communication device can utilize independent up link permission.Under situation, access terminal and explain bit mapping and up link permission as follows with the permission of routine (independent) up link.The re-transmission of up link permission indication scheduling, wherein first transmission is a continuous dispatching.The permission of this up link can be interpreted as the ACK that negates.According to some schemes, the up link permission has precedence over the HARQ feedback, and wherein, the bit mapping can be represented the HARQ feedback.Should the Resource Block bit field of correspondence of mapping be set to " 0 ", not to be scheduled for the re-transmission of Resource Block bit mapping to the given Resource Block of indication that accesses terminal.
According to some schemes, utilize adaptive bandwidth control with the mapping of Resource Block bit.If distributed more than single least resource piece, so being mapped to above a bit of Resource Block bit mapping accessed terminal for accessing terminal.Redundant bit in the mapping of Resource Block bit can be used to adjust the transmission bandwidth that is used to retransmit.For example, be used for first transmission or accessing terminal of retransmitting, in the resource mapping, distribute N bit so if N resource block assignments given.If only individual bit is set to 1, this can indicate the continuation that HARQ retransmits so.All the other N-1 bit can be used for adjusting the bandwidth (supposing identical MCS) that is used to retransmit.As an example, each " 1 " in the bit mapping is corresponding to each least resource piece of being dispatched.
