Description

HARQ process transmission method and device, base station and terminal in unauthorized frequency range

Technical field

The present invention relates to communication technical field, in particular to the HARQ process transmission side in a kind of unauthorized frequency range HARQ process transmission device in method, a kind of unauthorized frequency range, a kind of base station and a kind of terminal.

Background technology

Along with sharply increasing of message volume, 3GPP mandate frequency spectrum seems and is increasingly not enough to provide higher network to hold Amount.In order to improve the utilization of frequency spectrum resource further, 3GPP proposes LAA, and (LTE Assisted Access, LTE auxiliary connects Enter) concept, for by LTE (Long Term Evolution, Long Term Evolution) authorize frequency spectrum help use unauthorized Frequency spectrum.In order to make the different system harmonious coexistences such as such as Wi-Fi in LTE system and unauthorized frequency range, 3GPP also been proposed LBT (Listen Before Talk, listem-before-talk) mechanism, to ensure in unauthorized frequency range by the usufructuary mode of competitive channel Different system use frequency spectrum resource fairness.Wherein, LTE system can be TDD in the working method of unlicensed spectrum (Time Division Duplexing, time division duplex) pattern, supplementary descending (SDL, Supplemental Downlink) mould Formula or the pattern of dynamically up-downgoing.

Wherein, the physical layer frame structure of TD-LTE is 10ms, contains the field of two 5ms, and its ascending-descending subframes configures As shown in table 1:

Table 1

As shown in table 1, for the TDD structure of 5ms downstream-to-upstream change-over period, 1 frame comprises 8 normal sub-frames and 2 Individual special subframe, and 8 normal sub-frames are to be referred to table 1 for up or descending on earth.And 10ms is gone downwards to The TDD structure of up change-over period, 1 frame comprises 9 normal sub-frames and a special subframe, and 9 normal sub-frames are on earth Being for the up or descending table 1 that is referred to, each normal sub-frames comprises again 14 symbol (symbol).

HARQ (Hybrid Automatic Repeat Request, hybrid automatic repeat-request) mechanism is in LTE system Ensure the important component part of transmission reliability, and the HARQ process sequential in different sub-frame configuration ensure that running time-frequency resource is high Effect utilizes.Traditional HARQ sequential is descending uses asynchronous system, i.e. receiving terminal does not knows the moment that transmission occurs in advance, because of This needs the HARQ process number of signaling instruction current transmission in asynchronous HARQ.Asynchronous HARQ need not consider what head passed and retransmitted Sequence problem, therefore agreement define only from sending downlink data to up by PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) sequential relationship of feeding back ACK/NACK, the most as shown in table 2:

Table 2

As shown in table 2, the digital k in form represents: if downlink data transmits in subframe n, then the ACK/ of its correspondence Nack message will feed back in the subframe that subframe numbers is n+k；If n+k > 9, then explanation should be after current wireless frame First radio frames subframe numbers be (n+k) %10 subframe in feeding back ACK/nack message (% is complementation symbol)；Work as n+k > 19 Time, then feeding back ACK/nack message in the subframe that second radio frames subframe numbers is (n+k) %10 after current wireless frame.

Traditional HARQ sequential is up, and take is synchronous HARQ, and the transmission of a HARQ process and retransmitting has solid Fixed sequential relationship, due to the generation moment of the previously known transmission of receiving terminal, therefore need not extra signaling to represent HARQ Process number.Agreement defines two sequential relationships to uplink synchronous HARQ, and one is at PDCCH (Physical from base station Downlink Control Channel, Physical Downlink Control Channel) it is upper that to send out upstream dispatching instructions the most up to terminal transmission The sequential relationship of data, another is to send the upstream data sequential relationship to base station feedback ACK/NACK from terminal.Wherein, table 3 give terminal sends upstream data to the sequential relationship of base station feedback ACK/NACK:

Table 3

As shown in table 3, the digital k in form represents: transmit in the subframe that subframe numbers is n if up data, then ACK/NACK feedback in PHICH (Physical Hybird ARQ Indicator Channel, Physical HARQ Indicator Channel) Information is transmitted in the subframe that subframe numbers is n+k.If n+k occurs > situation of 9 or n+k > 19, then according to descending HARQ sequential The processing mode of same condition processes.

Owing to authorizing LTE access system in frequency range can use channel resource at any time, so during HARQ process Sequence shows good seriality.But owing to unauthorized frequency range introduces LBT mechanism so that LTE system can not be all the time All busy channel resources, if HARQ mechanism still uses the timing planning authorized in frequency range, then may result in HARQ process Take in the transmission data moment that sequential specifies and can not transmit data less than channel resource.If a certain HARQ process always goes out Existing such situation, it will increase the average delay of HARQ process, reduces Consumer's Experience.Concrete problem is as follows:

As it is shown in figure 1, as a example by the configuration #1 of tdd mode, base station is when 0 work song frame busy channel resource of radio frames 1 It is successfully transmitted the data of descending HARQ process 1.And 4 work song frames of the 4 of radio frames 1,5 work song frames and radio frames 2 are not owing to robbing Account for channel resource, cause sending the downlink data in process 3,4,2.

For ascending HARQ course, equally exist moment of regulation because of can not busy channel and upstream data can not be sent Situation.As in figure 2 it is shown, equally as a example by TDD configuration #1, terminal sends upstream datas at 2 work song frames of radio frames 1, according to time Sequence rule, base station should be at the 6 work song frame feeding back ACKs/nack message of radio frames 1, and this sub-frame of uplink is successfully robbed and accounted for letter this moment Road, upstream data is successfully transmitted.But 3 work song frames of 7 work song frames of radio frames 1 and radio frames 2 are not owing to taking channel Resource, so upstream data can not be sent.

If always there is above-mentioned situation in some HARQ process, then the time delay of this HARQ process will be very big, respectively Individual HARQ process resource distributional equity can not be guaranteed, it is also possible to the situation of loss of data occurs, has a strong impact on use Family is experienced and throughput performance.

Therefore, how it can be avoided that HARQ process always takies can not send data less than channel resource, reduce HARQ The average delay of process, it is ensured that HARQ process utilizes the fairness of resource to become technical problem urgently to be resolved hurrily.

Summary of the invention

The present invention is based at least one above-mentioned technical problem, it is proposed that the HARQ in a kind of new unauthorized frequency range enters Journey transmission plan, can avoid HARQ process owing to always taking the problem causing sending data less than channel, reduce The average delay of HARQ process, it is ensured that utilize the fairness of resource between HARQ process, handling up of beneficially lifting system Amount.

In view of this, according to the first aspect of the invention, it is proposed that the HARQ process transmission side in a kind of unauthorized frequency range Method, including: statistical data transmitting terminal makes each HARQ process miss weight because performing Channel Detection mechanism in unauthorized frequency range Pass number of times, and/or add up each HARQ process from set up receive ACK message to data sending terminal before experienced time Long；Miss the number of times of re-transmission according to described each HARQ process, and/or described each HARQ process is from setting up to data sending terminal Receive the duration experienced before ACK message, determine the described each HARQ process transmission priority when retransmitting；? Detect when the channel of unauthorized frequency range can take, according to the described each HARQ process transmission preferences when retransmitting every time Level is to its allocation of transmission resources.

In this technical scheme, made because performing Channel Detection mechanism in unauthorized frequency range by statistical data transmitting terminal Each HARQ process misses the number of times of re-transmission, and/or adds up each HARQ process and receive ACK to data sending terminal and disappear from setting up The duration experienced before breath, determines each HARQ process transmission priority when retransmitting, and according to the biography determined Defeated priority come to its allocation of transmission resources so that the HARQ process bigger for missing the number of times of re-transmission, and/or from set up to Data sending terminal receive the longer HARQ process of the duration experienced before ACK message can by preferential allocation of transmission resources, And then it can be avoided that HARQ process is owing to always taking the problem causing sending data less than channel, reduces HARQ and enter The average delay of journey, it is ensured that utilize the fairness of resource between HARQ process, the handling capacity of beneficially lifting system.

Wherein, data sending terminal both can be base station, it is also possible to be terminal.When data sending terminal is base station, HARQ enters Journey is descending HARQ process；When data sending terminal is terminal, HARQ process is ascending HARQ course.

In technique scheme, it is preferable that the described each HARQ process transmission priority when retransmitting and institute State each HARQ process and miss the number of times of re-transmission, and/or described each HARQ process receives ACK from foundation to data sending terminal Experienced before message time grow up to positive correlation.

In this technical scheme, by making the HARQ process transmission priority when retransmitting and HARQ process miss weight The number of times passed becomes positive correlation so that the HARQ process missing the number of times of re-transmission the most can obtain higher transmission preferences Level, and then it can be avoided that HARQ process is owing to always taking the problem causing sending data less than channel, reduce The average delay of HARQ process；Similarly, by make the HARQ process transmission priority when retransmitting and HARQ process from Foundation grows up to positive correlation when being experienced before receiving ACK message to data sending terminal so that the HARQ that time delay is bigger Process can obtain higher transmission priority, and then can reduce the average delay of HARQ process.

In any of the above-described technical scheme, it is preferable that in the number of times and the institute that miss re-transmission according to described each HARQ process State the duration that each HARQ process was experienced before foundation receives ACK message to data sending terminal, determine described each In the case of the HARQ process transmission priority when retransmitting, determine the described each HARQ process biography when retransmitting The step of defeated priority, specifically includes: the number of times missing re-transmission according to described each HARQ process determines that described HARQ process exists Transmission priority during re-transmission；When the number of times that multiple HARQ processes miss re-transmission is identical, according to the plurality of HARQ process from Set up the duration experienced before receiving ACK message to data sending terminal and determine the plurality of HARQ process biography when retransmitting Defeated priority.

In any of the above-described technical scheme, it is preferable that the HARQ process transmission method in described unauthorized frequency range, also wrap Include: if arbitrary HARQ process misses the pre-determined number that reaches of the number of times of re-transmission, and/or arbitrary HARQ process is sent out from foundation to data Sending end receives the duration experienced before ACK message and reaches the first scheduled duration, then give up described arbitrary HARQ process.

In any of the above-described technical scheme, it is preferable that also include: if in the transmission money to described each HARQ course allocation After source, also has available transfer resource, it is determined whether there is a need to other HARQ process retransmitted；Retransmit if necessary its Its HARQ process, it is determined that the transmission priority of other HARQ process described, and according to the priority of other HARQ process described, To its allocation of transmission resources.

In this technical scheme, when after above-mentioned each HARQ course allocation transfer resource, if also having available biography Defeated resource, then may determine whether other HARQ process that there is a need to retransmit, and is determining other HARQ process that there is a need to retransmit Time, according to the priority of other HARQ process to its allocation of transmission resources, enabling ensure that transfer resource obtains sufficient profit With, improve the utilization rate of resource.Wherein, however, it is determined that do not need other HARQ process retransmitted, then can use remaining biography Defeated resource sets up new HARQ process.

In any of the above-described technical scheme, it is preferable that in the case of described HARQ process is descending HARQ process, according to The described each HARQ process transmission priority when retransmitting, to the step of its allocation of transmission resources, specifically includes: often When the secondary down channel unauthorized frequency range being detected can take, the transfer resource of the second scheduled duration that will start from present sub-frame Distribute to predetermined quantity HARQ process, wherein, if when described present sub-frame started before first non-descending sub frame Long more than or equal to predetermined value T, then using described predetermined value T as described second scheduled duration；If from the beginning of described present sub-frame Duration before first non-descending sub frame be less than described predetermined value T, then by described present sub-frame to the most described first non-under Duration before row subframe is as described second scheduled duration, and wherein, predetermined value T is channel maximum occupation time.

As shown in Figure 6, according to the HARQ process transmission device in the unauthorized frequency range of second embodiment of the present invention 600, including: statistic unit 602, determine unit 604 and allocation unit 606.

Wherein, statistic unit 602 is used for adding up terminal and makes each because performing Channel Detection mechanism in unauthorized frequency range Ascending HARQ course misses the number of times of re-transmission, and/or adds up each ascending HARQ course and receive ACK message from setting up to terminal The duration before experienced；Determine unit 604 for missing the number of times of re-transmission according to described each ascending HARQ course, and/or Described each ascending HARQ course from set up receive ACK message to terminal before the duration that experienced, determine described each on The row HARQ process transmission priority when retransmitting；Allocation unit 606 is for unauthorized frequency range being detected in terminal every time Channel when can take, according to the described each ascending HARQ course transmission priority when retransmitting to its distribution transmission money Source.

In this technical scheme, made on each because performing Channel Detection mechanism in unauthorized frequency range by statistics terminal Row HARQ process misses the number of times of re-transmission, and/or add up each ascending HARQ course from set up to terminal receive ACK message it Front experienced duration, determines each ascending HARQ course transmission priority when retransmitting, and according to the biography determined Defeated priority is come to its allocation of transmission resources so that the ascending HARQ course bigger for missing the number of times of re-transmission, and/or from building Founding the longer ascending HARQ course of the duration experienced before receiving ACK message to terminal can be by preferential distribution transmission money Source, and then it can be avoided that ascending HARQ course is owing to always taking the problem causing sending data less than channel, reduce The average delay of ascending HARQ course, it is ensured that utilize the fairness of resource between ascending HARQ course, be conducive to promoting system The handling capacity of system.

In technique scheme, it is preferable that the described each ascending HARQ course transmission priority when retransmitting With the number of times that described each ascending HARQ course misses re-transmission, and/or described each ascending HARQ course connects from setting up to terminal Experienced before receiving ACK message time grow up to positive correlation.

In this technical scheme, by making the ascending HARQ course transmission priority when retransmitting enter with ascending HARQ Journey is missed the number of times of re-transmission and is become positive correlation so that the ascending HARQ course missing the number of times of re-transmission the most can obtain higher Transmission priority, and then it can be avoided that ascending HARQ course causes less than channel sending data owing to always taking Problem, reduces the average delay of ascending HARQ course；Similarly, by making the ascending HARQ course transmission when retransmitting Priority and ascending HARQ course grow up to positive correlation when being experienced before foundation receives ACK message to terminal, make Obtain the bigger ascending HARQ course of time delay and can obtain higher transmission priority, and then the flat of ascending HARQ course can be reduced All time delays.

In any of the above-described technical scheme, it is preferable that at the number of times missing re-transmission according to described each ascending HARQ course The duration experienced before foundation receives ACK message to terminal with described each ascending HARQ course, determines described each In the case of the ascending HARQ course transmission priority when retransmitting, described determine unit 604 specifically for: according to described Each ascending HARQ course misses the number of times of re-transmission and determines the described ascending HARQ course transmission priority when retransmitting；Multiple Ascending HARQ course miss the number of times of re-transmission identical time, receive from setting up to terminal according to the plurality of ascending HARQ course The duration experienced before ACK message determines the plurality of ascending HARQ course transmission priority when retransmitting.

In any of the above-described technical scheme, it is preferable that the described ascending HARQ course transmitting device in unauthorized frequency range 600, also include: processing unit 608, miss re-transmission for counting on arbitrary ascending HARQ course at described statistic unit 602 Number of times reach pre-determined number, and/or arbitrary ascending HARQ course from set up receive ACK message to terminal before experienced When duration reaches the first scheduled duration, give up described arbitrary ascending HARQ course.

In any of the above-described technical scheme, it is preferable that described determine that unit 604 is additionally operable to: if in described allocation unit 606 After described each ascending HARQ course is assigned with transfer resource, also has available transfer resource, it is determined whether there is a need to Other ascending HARQ course retransmitted；Other ascending HARQ course retransmitted if necessary, it is determined that other ascending HARQ described The transmission priority of process, and according to the priority of other ascending HARQ course described, to its allocation of transmission resources.

In this technical scheme, when after above-mentioned each ascending HARQ course allocation of transmission resources, if also having available Transfer resource, then may determine whether to there is a need to other ascending HARQ course retransmitted, determining other that there is a need to retransmit During ascending HARQ course, according to the priority of other ascending HARQ course to its allocation of transmission resources, enabling ensure transmission Resource is fully utilized, and improves the utilization rate of resource.Wherein, however, it is determined that do not need other ascending HARQ retransmitted to enter Journey, then can use remaining transfer resource to set up new HARQ process.

In any of the above-described technical scheme, it is preferable that described allocation unit 606 specifically for: examine in described terminal every time Measure the up channel of unauthorized frequency range when can take, transfer resource corresponding for first sub-frame of uplink afterwards is distributed to excellent The ascending HARQ course that first level is the highest, and before second sub-frame of uplink later, continue to detect the letter of described unauthorized frequency range Road state；Or when the up channel that described terminal detects unauthorized frequency range can take every time, by first afterwards The transfer resource that predetermined quantity sub-frame of uplink that row subframe starts is corresponding distributes to predetermined quantity ascending HARQ course.

In this technical scheme, owing to the detection of up channel was carried out before sub-frame of uplink, if examine the most every time The up channel measuring unauthorized frequency range can take, then can be only by transfer resource distribution corresponding for a sub-frame of uplink thereafter To the ascending HARQ course that priority is the highest, it is required to before taking sub-frame of uplink detect channel status the most every time；Certainly, often When the secondary up channel unauthorized frequency range being detected can take, it is also possible to by transmission corresponding for predetermined quantity sub-frame of uplink thereafter Resource distributes to predetermined quantity ascending HARQ course.Wherein, there is two ways to determine the actual number of this predetermined quantity: one Planting is the number continuous print sub-frame of uplink after channel idle being detected, and the continuous print after channel idle i.e. being detected is up Subframe is all used for carrying out the transmission of ascending HARQ, has 3 sub-frame of uplink, then by these 3 after channel idle such as being detected Row subframe is all used for transmitting ascending HARQ course；Another kind is the portion in the continuous print sub-frame of uplink after channel idle to be detected Divide sub-frame of uplink, have 3 sub-frame of uplink after channel idle such as being detected, if front 2 sub-frame of uplink are all not allocated to it Its user, and the 3rd sub-frame of uplink is allocated to other user, then only take up front 2 sub-frame of uplink to carry out HARQ process Transmission, and after having taken, re-start the detection of channel.

Fig. 7 shows the schematic block diagram of terminal according to an embodiment of the invention.

As it is shown in fig. 7, terminal 700 according to an embodiment of the invention, including: in unauthorized frequency range as shown in Figure 6 HARQ process transmission device 600.

To sum up, technical scheme is primarily directed to unauthorized frequency range when being used by LTE system, it is proposed that based on The channel resource allocation method of HARQ process priority, it is to avoid some HARQ processes can not send less than channel because always taking The problem of data, reduces the average delay of HARQ process, it is ensured that utilize the fairness of resource between HARQ process.Wherein, Technical scheme is applicable not only to the scene that unauthorized frequency range is used by LTE system in the way of TDD, is also applied for non- Authorize frequency range in the way of SDL or scene that the mode of dynamically up-downgoing is used by LTE system.

Concrete the most as shown in Figure 8, according to the HARQ process transmission method of second embodiment of the present invention, including:

Step 802, data sending terminal determines the HARQ process needing to be retransmitted.Wherein, data sending terminal can be base station, also It can be terminal.

Step 804, data sending terminal competitive channel.

Step 806, it may be judged whether seize channel success, the most then perform step 808；Otherwise, competitive channel is continued.

Step 808, adds up time delay T{i} of each HARQ process, and the number of transmissions N led to miss because of LBT mechanism {i}。

Step 810, it is judged that whether there is the element that size is identical in N{i}, the most then perform step 812；Otherwise, perform Step 816.

Step 812, compares the element in the T{i} corresponding to the element that size in N{i} is identical, is i.e. having the transmission missed During the identical HARQ process of number of times, compare the time delay of these HARQ processes.

Step 814, carries out corresponding process descending according to the element size in T{i}.

Step 816, carries out corresponding process descending according to the element size in N{i}.

Step 818, determines the priority of HARQ process, wherein, sorts the most forward according to descending result, and priority is more Greatly.

Step 820, according to the priority sequence determined to HARQ course allocation channel resource.

Step 822, busy channel transmission HARQ process.After channel occupancy terminates, return step 804.

In the HARQ process transmission method shown in Fig. 8, in order to ensure communication quality, data sending terminal is in unauthorized frequency range Channel Detection must be carried out, when detecting that this frequency range does not has other different system to use or noise is less before upper transmission data Can use.When transmitting terminal detects that channel can use, transmitting terminal is according to the time delay of HARQ process and the biography missed because of LBT mechanism Defeated number of times carries out prioritization, carries out channel resource allocation with priority order from high to low after completing sequence.

Wherein, time delay refer to transmitting terminal after setting up HARQ process to experienced before receiving ACK message time Between；The number of transmissions missed refers to HARQ process and does not rob in the time that sequential specifies due to LBT mechanism and account for channel resource Cause can not normally sending the number of times retransmitting data.

The excellent of HARQ process is determined in the time delay of the HARQ process according to statistics and the number of transmissions missed because of LBT mechanism During first level, first being compared by the number of transmissions that HARQ process is missed because of LBT mechanism, number of times is the biggest, and priority is the highest；If going out The HARQ process that the number of transmissions that now misses is consistent, then compare their HARQ process delay, and time delay is the biggest, and priority is the highest. Finally twice result of the comparison is combined, obtain the prioritization of each HARQ process.Other reality in the present invention Execute in example, it is also possible to according only to the time delay of HARQ process or the number of transmissions that misses because of LBT mechanism to determine the excellent of HARQ process First level.

Illustrate respectively below for descending HARQ process and ascending HARQ course:

One, descending HARQ process.

1, when needs transmission downlink data, base station carries out Channel Detection, can in the Tms after competition to channel resource With busy channel.Wherein, statistics HARQ process delay refers to that accounting base-station has sent, but does not receives under ACK feedback The time delay of row HARQ process；The number of transmissions that statistics HARQ process is missed refers to add up the descending HARQ having received NACK feedback Process misses the number of times of re-transmission.

2, when Resources allocation, resource is to distribute to the HARQ process that priority is higher in units of subframe.Wherein, exist When channel idle being detected, multiple descending sub frame can be taken continuously to transmit HARQ process, such as the frame shown in Fig. 9 be tied Structure, when channel idle being detected, according to the priority of HARQ process, transmits successively in ensuing 6 descending sub frames HARQ process 3, HARQ process 6, HARQ process 1, HARQ process 5, HARQ process 2, HARQ process 4.Wherein, take continuously many Individual subframe determines according to channel maximum occupation time and continuous print descending sub frame number, if continuous print descending sub frame time Long not up to channel maximum occupation time, then can take the multiple descending sub frame of this continuous print, if continuous print descending sub frame time Long more than channel maximum occupation time, then channel is taken duration and is channel maximum occupation time.

If the channel duration shared by HARQ process that 3 are added up is less than channel maximum holding time T, then met After the HARQ course allocation resource of condition, the statistics of the HARQ process priority that can try again, with by remaining down channel Resource dispenses, by that analogy.If the HARQ process not met after Tong Ji, and down channel resources also residue, Then this resource is not allocated.

If 4 at the end of a Channel holding time, part HARQ process is still had to be not allocated to channel resource, Then these processes will not obtain any resource, and they will participate in the resource distribution after busy channel next time.

5, HARQ process priority after the busy channel of base station judges separate each time, is independent of each other, every time Priority result of determination is only used for current channel resource allocation.

6, when the feedback information of some the descending HARQ process received when base station is ACK confirmation, this process Time delay and the number of transmissions missed then reset.

If 7 present sub-frame directions are up, and descending holding time is not over, then terminate sending out of downlink data Sending, holding time T resets.

8, when the number of times missing transmission when a descending HARQ process reaches pre-determined number (such as 4 times), then this HARQ is abandoned The data of process, and the time delay of this descending HARQ process and the number of transmissions missed are reset.

9, the feedback timing planning of HARQ process still can adopt TD-LTE system in mandate frequency range in mandate frequency range In descending HARQ timing planning.

Two, ascending HARQ course.

1, when needs transmission upstream data, terminal carries out Channel Detection, when channel idle being detected, sends to base station Upstream data.Owing to the maximum holding time of up channel is 1ms, and according to the seriality of sub-frame of uplink and detection mode, Resource distribution mode is broadly divided into following two:

Mode one: as shown in Figure 10 A, when sub-frame of uplink individualism, is the most all non-sub-frame of uplink, then enters according to HARQ The priority of journey, by channel resource allocation to the highest ascending HARQ course of priority.

Mode two: as shown in Figure 10 B, when sub-frame of uplink continued presence, the detection mode of up channel has two kinds: a kind of It is to detect before each sub-frame of uplink, determines whether to transmit HARQ process on this sub-frame of uplink according to testing result； Another kind be robbed before any one sub-frame of uplink wherein and account for channel resource after, if remaining up son after this subframe Frame, follow-up Channel Detection of can no longer doing, direct busy channel, until running into descending sub frame or base station by follow-up up son Frame is distributed to other user and is used.

Wherein, when doing Channel Detection before each sub-frame of uplink, however, it is determined that up channel can be taken, then will letter Road resource distributes to the ascending HARQ course that priority is the highest；When the channel detection process before any one sub-frame of uplink is robbed When accounting for direct busy channel on channel resource and n later continuous sub-frame of uplink, this n+1 sub-frame of uplink can be divided More much higher HARQ process of dispensing priority.

2, in the HARQ timing planning of TD-LTE, ascending HARQ is to synchronize, and it is fixing for i.e. sending and retransmit sequential, And in the present invention, by carrying out Resources allocation thus according to priority, the sequential that therefore upstream data sends and retransmits is not fixing , the most in the inventive solutions, ascending HARQ is asynchronous transmission.

3, the ascending HARQ course time delay of statistics refers to that adding up terminal has sent, but does not receives the upper of ACK feedback The time delay of row HARQ process；The number of transmissions that statistics HARQ misses refers to add up the ascending HARQ course having received NACK feedback Miss the number of times of re-transmission.

If the 4 HARQ number of processes sums less than continuous sub-frame of uplink carrying out prioritization, then give qualified After HARQ course allocation resource, the statistics of the HARQ process priority that tries again, remaining uplink channel resources is dispensed, By that analogy.If the HARQ process not met after Tong Ji, channel resource also has residue, then these resources are not carried out point Join.

If at the end of 5 Channel holding times, part ascending HARQ course is still had to be not allocated to channel money Source, these processes will not obtain any resource.They will participate in the resource distribution after busy channel next time.

6, HARQ process priority after terminal busy channel judges separate each time, is independent of each other, every time Priority result of determination is only used for current channel resource allocation.

7, when the feedback information of some ascending HARQ course that terminal receives is ACK confirmation, this process Time delay and the number of transmissions missed then reset.

8, when the number of times missing transmission when an ascending HARQ course reaches pre-determined number (such as 4 times), then this HARQ is abandoned The data of process, and the time delay of this ascending HARQ course and the number of transmissions missed are reset.

9, the feedback timing planning of HARQ process still can adopt TD-LTE system in mandate frequency range in mandate frequency range In ascending HARQ timing planning.

Technical scheme being described in detail above in association with accompanying drawing, the present invention proposes a kind of new unauthorized frequency range On HARQ process transmission scheme, HARQ process can be avoided to cause less than channel sending data owing to always taking Problem, reduces the average delay of HARQ process, it is ensured that utilize the fairness of resource between HARQ process, is conducive to promoting system The handling capacity of system.

The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies Change, equivalent, improvement etc., should be included within the scope of the present invention.
