Abstract

The invention provides a method and a system for scheduling uplink sub-frames to solve the problem of limited cell capacity caused by the fact that the existing scheduling method is incapable of scheduling more users due to the limited PDCCH (Physical Downlink Control Channel) resources resulting from PDCCH resource waste. The method provided by the invention can simultaneously schedule two uplink sub-frames in relative to one downlink sub-frame according to different to-be-transmitted data by selecting different scheduling manners. Single frame scheduling is preferred when the to-be-transmitted data is transmitted for the first time; multi-frame scheduling is preferred when the to-be-transmitted data is retransmitted. By dynamically selecting the scheduling manners, the method can bear resources allocated to two different uplink sub-frames by issues a PDCCH when adopting multi-frame scheduling, thereby saving PDCCH resources, scheduling more users, and improving the cell capacity.

Embodiment

For the application's above-mentioned purpose, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments, the application is described in further detail.

The method and system of the dispatching uplink subframe that the application proposes is by Dynamic Selection scheduling mode, when adopting multiframe scheduling, by issuing a PDCCH, can be carried as the resource that two different sub-frame of uplink distribute, thereby can save PDCCH resource, dispatch more user, increase cell capacity.

The method of the application's dispatching uplink subframe is that the situation of simultaneously dispatching two different sub-frame of uplink for descending sub frame in LTE-TDD system is processed.The wireless frame structure of LTE-TDD system applies is the type2 radio frames of definition in 3GPP TS 36.211, and the length of this radio frames is 10s, is divided into the subframe that 10 length are 1s, and the data of uplink and downlink are transmitted in different subframe in same frame.In LTE-TDD system, for type2 wireless frame structure, defined 7 kinds of different ascending-descending subframes configurations, as shown in table 1:

Table 1

Wherein, what Uplink-downlink configuration mono-list was shown is the config. number of ascending-descending subframes configuration, is respectively configuration 0, configuration 1 ... configuration 7;

What Downlink-to-Uplink Switch-point periodicity mono-list was shown is that (TDD is according to time differentiating uplink and downlink for ascending-descending subframes switching cycle, so one direction resource is discontinuous in time, a period of time is up, a period of time is descending, switching is exactly the conversion process of uplink and downlink), described ascending-descending subframes switching cycle is 5ms or 10ms;

What Subframe number represented is the sequence number of subframe, is respectively subframe 0, subframe 1 ... subframe 9, " D " represents that this subframe is descending sub frame, and " U " represents that this subframe is sub-frame of uplink, and " S " represents special subframe, and described special subframe is also descending sub frame.Corresponding to the type2 frame structure shown in Fig. 2, the subframe that wherein comprises DwPTS (downlink pilot time slot), GP (guard period) and UpPTS (uplink pilot time slot) is special subframe.

Corresponding to 7 kinds in above-mentioned table 1 different ascending-descending subframes configurations, the scheduling sequential of its correspondence is as shown in table 2:

Table 2

The rule of scheduling sequential is descending sub frame scheduling oneself, may dispatch certain sub-frame of uplink simultaneously, and time point corresponding to sub-frame of uplink being scheduled always lags behind time point corresponding to scheduling subframe.In table 2, can the concurrent subframe numbers of serving downstream grants frame of operation dispatching in the corresponding ascending-descending subframes configuration of numeral shown in " Scheduling subframe number "; In " Subframe number " each sequence of subframes number below this subframe of corresponding numeral in which subframe, be scheduled.

For example, for ascending-descending subframes configuration 1, subframe 0 is descending sub frame, dispatches oneself, and subframe 0; Subframe 1 is descending sub frame, dispatches oneself, and subframe 1, dispatches the sub-frame of uplink 7 in this radio frames simultaneously; Subframe 2 is sub-frame of uplink, at the descending

sub frame

5 or 6 of last radio frames, is scheduled.

As can be seen from Table 2, only at ascending-descending subframes, configure at 0 o'clock there will be a descending sub frame to dispatch the situation of two sub-frame of uplink simultaneously.For example descending sub frame n can dispatching uplink subframe n+k or sub-frame of uplink n+7 (specifically control n dispatching uplink subframe n+k of descending sub frame or dispatching uplink subframe n+7 only by UL index (2bit) field in descending control signaling DCI Format0, or simultaneously dispatching uplink subframe n+k and sub-frame of uplink n+7).The sequence number that wherein n is descending sub frame, k is the time delay between descending sub frame n and the sub-frame of uplink that is scheduled, described time delay be take subframe as unit.

Its scheduling relation is as shown in table 3:

Table 3

As can be seen from Table 3, descending sub frame 0 can dispatching

uplink subframe

4 or 7, or dispatching

uplink subframe

4 and 7 simultaneously, and descending sub frame 1 can dispatching

uplink subframe

7 or 8, or dispatching

uplink subframe

7 and 8 etc. simultaneously, introduces no longer in detail.

Wherein, in 3GPP agreement, stipulated the value of k, as shown in table 4:

Table 4

Wherein, the config. number of ascending-descending subframes configuration is shown in TDD UL/DL Configuration mono-list, sequence of subframes n is shown in DL subframe number n mono-list, when sequence of subframes number numeral is below n corresponding to current ascending-descending subframes configuration neutron number of frames, and the value of k.For example, for ascending-descending subframes configuration 0, when descending sub frame is subframe 0, k=4, when descending sub frame is subframe 1, k=6 etc.

As shown in Figure 3, be a kind of subframe scheduling sequential schematic diagram, the descending sub frame 0 in figure in radio frames SFNn only carries out single frames scheduling, and dispatching uplink subframe 4; Descending sub frame 1 carries out multiframe scheduling, dispatches the sub-frame of

uplink

7 and 8 in this radio frames simultaneously; Descending sub frame 5 only carries out single frames scheduling, and dispatching uplink subframe 9; Descending sub frame 6 carries out multiframe scheduling, dispatches the sub-frame of

uplink

2 and 3 in next radio frames SFNn+1 simultaneously.

For the subframe scheduling sequential shown in Fig. 3, base station can constantly successively issue two PDCCH to same UE in same descending sub frame scheduling at present, is carried as respectively the resource that two different sub-frame of uplink distribute, to complete the scheduling to two sub-frame of uplink.But this method can be wasted PDCCH resource to a certain extent, cause cannot dispatching more users because PDCCH is resource-constrained, cause cell capacity limited.

For above-mentioned situation, the embodiment of the present application one has proposed a kind of method of dispatching uplink subframe, and wherein, described sub-frame of uplink comprises the first sub-frame of uplink and the second sub-frame of uplink, and as shown in Figure 4, described method comprises:

Step S401, judgement data to be transferred is just to pass data or data retransmission;

The embodiment of the present application, for different first biography data, will adopt different dispatching methods, and the method for first biography data acquisition with passive execution multiframe scheduling, adopts the method for initiatively carrying out multiframe scheduling for data retransmission.

Therefore, first will judge data to be transferred is just to pass data or data retransmission.

It should be noted that, multiframe scheduling described in the embodiment of the present application refers at a descending sub frame only dispatches two sub-frame of uplink by sending a PDCCH simultaneously, and described single frames scheduling refers at a descending sub frame dispatches a sub-frame of uplink by sending a PDCCH.

Step S402, if just pass data, enters and just spreads journey, judges whether the first sub-frame of uplink or the second sub-frame of uplink meet the condition of fill order's frame scheduling;

Step S403, if meet the condition of fill order's frame scheduling, dispatches the preferential fill order's frame scheduling of the first sub-frame of uplink or the second sub-frame of uplink;

Step S404, if do not meet the condition of fill order's frame scheduling, dispatches the first sub-frame of uplink and the second sub-frame of uplink and carries out multiframe scheduling;

When judging data to be transferred for first biography data, enter and just spread journey, the method to first biography data acquisition with passive execution multiframe scheduling.Therefore, in above-mentioned steps S402-S404, first judge whether the first sub-frame of uplink or the second sub-frame of uplink meet the condition of fill order's frame scheduling, if meet, dispatch the preferential fill order's frame scheduling of the first sub-frame of uplink or the second sub-frame of uplink, when not meeting the condition of fill order's frame scheduling, just selection scheduling the first sub-frame of uplink and the second sub-frame of uplink are carried out multiframe scheduling.

Step S405, if data retransmission enters re-transmission flow process, judges whether the first sub-frame of uplink and the second sub-frame of uplink meet the condition of carrying out multiframe scheduling;

Step S406, if meet the condition of carrying out multiframe scheduling, dispatches the first sub-frame of uplink and the second sub-frame of uplink and preferentially carries out multiframe scheduling;

Step S407, if do not meet the condition of carrying out multiframe scheduling, dispatches the first sub-frame of uplink or the second sub-frame of uplink fill order frame scheduling.

When judging data to be transferred and be data retransmission, enter re-transmission flow process, to retransmitting the method for initiatively carrying out multiframe and dispatching for data acquisition.Therefore, in above-mentioned steps S405-S407, first judge whether the first sub-frame of uplink or the second sub-frame of uplink meet the condition of carrying out multiframe scheduling, if meet, dispatch the first sub-frame of uplink and the second sub-frame of uplink and preferentially carry out multiframe scheduling, when not meeting the condition of carrying out multiframe scheduling, ability selection scheduling the first sub-frame of uplink or the second sub-frame of uplink fill order frame scheduling.

The situation that the embodiment of the present application is dispatched two sub-frame of uplink for a descending sub frame simultaneously, according to different data to be transferred, selects different scheduling modes to dispatch described sub-frame of uplink.Due to multiframe scheduling process more complicated, therefore, for first biography data, passive use multiframe scheduling can obviously reduce the processing complexity of base station equipment to the embodiment of the present application on the one hand, especially under the more scene of small data quantity business, on the other hand, can also adaptively between single frames scheduling and multiframe scheduling, select bearing capacity compared with the superior, thus optimization system performance; For data retransmission, initiatively use multiframe scheduling, to improve the efficiency of transfer of data, reduce service delay, promote user awareness.

The embodiment of the present application, by Dynamic Selection scheduling mode, when adopting multiframe scheduling, by issuing a PDCCH, can be carried as the resource that two different sub-frame of uplink distribute, thereby can save PDCCH resource, dispatches more user, increases cell capacity.

Below, the method for concrete dispatching uplink subframe is introduced.

In the present embodiment, by descending sub frame n, dispatch described the first sub-frame of uplink and/or the second sub-frame of uplink, the sequence number that wherein n is described descending sub frame.Described the first sub-frame of uplink is n+k, and described the second sub-frame of uplink is n+7; Wherein, k is the time delay between described descending sub frame n and described the first sub-frame of uplink n+k, and described time delay be take subframe as unit.

Certainly, the first sub-frame of uplink in the present embodiment can be also n+7, and the second sub-frame of uplink is n+k; Wherein, k is the time delay between described descending sub frame n and the second sub-frame of uplink n+k, and described time delay be take subframe as unit, and those skilled in the art carry out respective handling according to actual conditions, and the embodiment of the present application is not limited this.

With reference to Fig. 5, show the flow chart of the method for a kind of dispatching uplink subframe described in the embodiment of the present application two, described method comprises:

Step S501, carries out prioritization to each subscriber equipment;

First, for subscriber equipment to be scheduled (referring to has the subscriber equipment that just passes data or have data retransmission to transmit in the up buffer of base station side record), according to certain rule, carry out prioritization.

Wherein, while carrying out prioritization, can consider assurance bit rate (the Guaranteed Bit Rate of business, GBR) attribute, whether there is data to be transferred and pagefile (Page File, PF), RR, MaxC/I etc. sort, for concrete sequencer procedure those skilled in the art, according to actual conditions, carry out respective handling, the present embodiment is discussed no longer in detail at this.

Step S502, takes out the highest subscriber equipment of priority, and judgement base station need to send to the data to be transferred of this subscriber equipment for just passing data or data retransmission;

Step S503, if just pass data, enters and just spreads journey;

Step S504, if data retransmission enters re-transmission flow process.

As shown in Figure 6, be the first biography flow chart described in the present embodiment two, describedly just spread journey and specifically comprise the following steps:

Step a1, obtains the described total amount D that just passes data _init;

Step a2, is sub-frame of uplink n+k Resources allocation, and to record Resources allocation be R (n+k), obtains the data volume D (n+k) that R (n+k) carries, and records that remaining just to pass data volume be D _wait(n+k)=D _init-D (n+k);

The resource of wherein distributing for sub-frame of uplink is Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH), and PUSCH is used for carrying the described data that just pass.

Step a3, judges that remaining just biography data volume is D _wait(n+k) whether be 0;

If so, illustrate that sub-frame of uplink n+k meets the condition of fill order's frame scheduling, the single frames scheduling of execution step a22, according to resource R (n+k) dispatching uplink subframe n+k; If not, perform step a4.

Step a4, is sub-frame of uplink n+7 Resources allocation, and to record Resources allocation be R (n+7), obtains the data volume D (n+7) that R (n+7) carries, and records that remaining just to pass data volume be D _wait(n+7)=D _init-D (n+7);

Step a5, judges that remaining just biography data volume is D _wait(n+7) whether be 0;

If so, illustrate that sub-frame of uplink n+7 meets the condition of fill order's frame scheduling, the single frames scheduling of execution step a22, according to resource R (n+7) dispatching uplink subframe n+7; If not, perform step a6.

Can above-mentioned steps a1-step a5 carry the process that all just passes data while being mainly judgement fill order frame scheduling.If D _wait(n+k) be 0, an explanation dispatching uplink subframe n+k can carry whole first biography data, and sub-frame of uplink n+k meets the condition of fill order's frame scheduling; If D _wait(n+7) be 0, an explanation dispatching uplink subframe n+7 can carry whole first biography data, and sub-frame of uplink n+7 meets the condition of fill order's frame scheduling.

If can carry whole first biography data by fill order's frame scheduling in the present embodiment, preferentially select single frames scheduling.

Step a6, judgement D _wait(n+k) whether/D (n+k) is less than default threshold value;

If (be D _wait(n+k)/D (n+k) is less than default threshold value), perform step a7; (be D if not _wait(n+k)/D (n+k) is more than or equal to default threshold value), perform step a14.

Step a7, the maximum D of the first biography data that record can carry _trans1=D (n+k);

Step a8, judgement D _wait(n+7) whether/D (n+7) is less than default threshold value;

If (be D _wait(n+7)/D (n+7) is less than default threshold value), perform step a9; (be D if not _wait(n+7)/D (n+7) is more than or equal to default threshold value), perform step a11.

Step a9, the maximum D of the first biography data that record can carry _trans2=D (n+7);

Step a10, judgement D _trans1whether be greater than D _trans2;

If D _trans1be greater than D _trans2, illustrating that sub-frame of uplink n+k meets the condition of fill order's frame scheduling, the single frames scheduling of execution step a22, according to resource R (n+k) dispatching uplink subframe n+k; If D _trans1be less than D _trans2, illustrating that sub-frame of uplink n+7 meets the condition of fill order's frame scheduling, the single frames scheduling of execution step a22, according to resource R (n+7) dispatching uplink subframe n+7; If D _trans1equal D _trans2, illustrating that sub-frame of uplink n+k or sub-frame of uplink n+7 meet the condition of fill order's frame scheduling, the single frames scheduling of execution step a22, according to resource R (n+k) dispatching uplink subframe n+k or according to resource R (n+7) dispatching uplink subframe n+7.

Above-mentioned steps a6-step a10 is mainly while judging according to resource R (n+k) or resource R (n+7) fill order frame scheduling in step 1-step 5, after all can not carrying whole first biography data, the process of the resource that the resource that multiframe scheduling is carried out in judgement to be needed needs while whether being greater than fill order's frame scheduling.

Concrete, by the remaining data volume D that just passes after fill order's frame scheduling _waitthe resource that any scheduling of ratio in judgement of the first biography data volume D carrying while dispatching with single frames needs is more.If described ratio is less than default threshold value, explanation is carried out multiframe and is dispatched the resource needing when the resource needing is greater than fill order's frame scheduling.

Preferably, described default threshold value is 0.9, and certain described threshold value can be also other numerical value, and the application is not limited this.

In the embodiment of the present application, if judge execution multiframe, dispatch the resource needing when the resource needing is all greater than according to resource R (n+k) with according to resource R (n+7) fill order frame scheduling, preferentially select single frames scheduling.

Step a11, judges the on all four resource of resource R (n+7) whether existing in the idling-resource of sub-frame of uplink n+k with described sub-frame of uplink n+7;

If so, perform step a12; If not, perform step a9.

In step a8, judge D _wait(n+7) when/D (n+7) is more than or equal to default threshold value, the resource that the resource of carrying out multiframe scheduling and needing needs while being less than according to resource R (n+7) fill order frame scheduling is described, therefore can consider according to resource R (n+7) simultaneously dispatching uplink subframe n+k and n+7 to carry out multiframe scheduling.

But if carry out multiframe scheduling according to resource R (n+7), also need further to meet the condition in this step a11.Owing to carrying out multiframe scheduling, the relevant field in DCI format0 can not be respectively two resources that the sub-frame allocation that is scheduled is different, thereby needs to guarantee that the resource of two sub-frame of uplink being scheduled is in full accord.

Therefore, in this step a11, if judge, in the idling-resource of sub-frame of uplink n+k, there is the on all four resource of resource R (n+7) with described sub-frame of uplink n+7, just may according to resource R (n+7) simultaneously dispatching uplink subframe n+k and n+7 to carry out multiframe scheduling; If judge, in the idling-resource of sub-frame of uplink n+k, there is not the on all four resource of resource R (n+7) with described sub-frame of uplink n+7, will return to step a9, with fill order's frame scheduling.

Step a12, the maximum D of the first biography data that record can carry _trans2=min (2*D (n+7), D _init);

Owing to judging the on all four resource of resource R (n+7) existing in the idling-resource of sub-frame of uplink n+k with described sub-frame of uplink n+7 in step a11, explanation can consider according to resource R (n+7) simultaneously dispatching uplink subframe n+k and n+7 to carry out multiframe scheduling.

The maximum of the first biography data that now, resource R (n+7) can carry should be D _trans2=min (2*D (n+7), D _init).

Step a13, judgement D _trans1whether be greater than D _trans2;

If D _trans1be more than or equal to D _trans2, illustrating that sub-frame of uplink n+k meets the condition of fill order's frame scheduling, the single frames scheduling of execution step a22, according to resource R (n+k) dispatching uplink subframe n+k; If D _trans1be less than D _trans2, perform step the multiframe scheduling of a23, according to resource R (n+7) while dispatching uplink subframe n+k and n+7.

Because the embodiment of the present application is for first biography high priority data fill order frame scheduling, therefore, work as D _trans1equal D _trans2time, select single frames scheduling, according to resource R (n+k) dispatching uplink subframe n+k.

Judge the on all four resource of resource R (n+7) existing in the idling-resource of sub-frame of uplink n+k with described sub-frame of uplink n+7 in step a11 after, also need further by this step, to judge whether the data volume that fill order's frame scheduling can carry is greater than the data volume that the scheduling of execution multiframe can be carried, the data volume that can carry when fill order's frame scheduling is more than or equal to while carrying out the data volume that multiframe scheduling can carry, and preferentially selects single frames scheduling.

Step a14, judges the on all four resource of resource R (n+k) whether existing in the idling-resource of sub-frame of uplink n+7 with described sub-frame of uplink n+k;

If so, perform step a15; If not, perform step a7.

In step a6, judge D _wait(n+k) when/D (n+k) is more than or equal to default threshold value, the resource that the resource of carrying out multiframe scheduling and needing needs while being less than according to resource R (n+k) fill order frame scheduling is described, therefore can consider according to resource R (n+k) simultaneously dispatching uplink subframe n+k and n+7 to carry out multiframe scheduling.

But the description by above-mentioned steps a11 can be learnt, if carry out multiframe scheduling according to resource R (n+k), also needs further to meet the condition in this step a14.In this step a14, if judge, in the idling-resource of sub-frame of uplink n+7, there is the on all four resource of resource R (n+k) with described sub-frame of uplink n+k, just may according to resource R (n+k) simultaneously dispatching uplink subframe n+k and n+7 to carry out multiframe scheduling; If judge, in the idling-resource of sub-frame of uplink n+7, there is not the on all four resource of resource R (n+7) with described sub-frame of uplink n+k, will return to step a7, to judge, need fill order's frame scheduling or multiframe scheduling.

Step a15, the maximum D of the first biography data that record can carry _trans1=min (2*D (n+k), D _init);

Owing to judging the on all four resource of resource R (n+k) existing in the idling-resource of sub-frame of uplink n+7 with described sub-frame of uplink n+k in step a14, explanation can consider according to resource R (n+k) simultaneously dispatching uplink subframe n+k and n+7 to carry out multiframe scheduling.

The maximum of the first biography data that now, resource R (n+k) can carry should be D _trans1=min (2*D (n+k), D _init).

Step a16, judgement D _wait(n+7) whether/D (n+7) is less than default threshold value;

If (be D _wait(n+7)/D (n+7) is less than default threshold value), perform step a17; (be D if not _wait(n+7)/D (n+7) is more than or equal to default threshold value), perform step a19.

In the idling-resource of judging sub-frame of uplink n+7, after the on all four resource of resource R (n+k) of existence and described sub-frame of uplink n+k, also need further for sub-frame of uplink n+7 judgement D _wait(n+7) whether/D (n+7) is less than default threshold value, to detect execution multiframe, dispatches the resource needing when whether the resource needing is greater than according to resource R (n+7) fill order frame scheduling.

Step a17, the maximum D of the first biography data that record can carry _trans2=D (n+7);

If judge D in step a16 _wait(n+7)/D (n+7) is less than default threshold value, explanation is carried out multiframe and is dispatched the resource needing when whether the resource needing is greater than according to resource R (n+7) fill order frame scheduling, therefore will further judge and need fill order's frame scheduling or multiframe scheduling.

Now, record the maximum D of the first biography data that resource R (n+7) can carry _trans2=D (n+7).

Step a18, judgement D _trans1whether be greater than D _trans2;

If D _trans1be less than or equal to D _trans2, illustrating that sub-frame of uplink n+7 meets the condition of fill order's frame scheduling, the single frames scheduling of execution step a22, according to resource R (n+7) dispatching uplink subframe n+7; If D _trans1be greater than D _trans2, perform step the multiframe scheduling of a23, according to resource R (n+k) while dispatching uplink subframe n+k and n+7.

A13 is similar to step, because the embodiment of the present application is selected single frames scheduling for first biography high priority data, therefore, in this step, judge the data volume that can carry according to resource R (n+7) fill order frame scheduling and be more than or equal to while dispatching according to resource R (n+k) execution multiframe the data volume that can carry, fill order's frame scheduling.

Step a19, judges the on all four resource of resource R (n+7) whether existing in the idling-resource of sub-frame of uplink n+k with described sub-frame of uplink n+7;

If so, perform step a20; If not, perform step a17.

In step a16, judge D _wait(n+7) when/D (n+7) is more than or equal to default threshold value, the resource that the resource of carrying out multiframe scheduling and needing needs while being less than according to resource R (n+7) fill order frame scheduling is described, therefore can consider according to resource R (n+7) simultaneously dispatching uplink subframe n+k and n+7 to carry out multiframe scheduling.

But if carry out multiframe scheduling according to resource R (n+7), also need further to meet the condition in this step a16.In this step a16, if judge, in the idling-resource of sub-frame of uplink n+k, there is the on all four resource of resource R (n+7) with described sub-frame of uplink n+7, just may according to resource R (n+7) simultaneously dispatching uplink subframe n+k and n+7 to carry out multiframe scheduling; If judge, in the idling-resource of sub-frame of uplink n+k, there is not the on all four resource of resource R (n+7) with described sub-frame of uplink n+7, will return to step a17, to judge, need fill order's frame scheduling or multiframe scheduling.

Step a20, the maximum D of the first biography data that record can carry _trans2=min (2*D (n+7), D _init);

Owing to judging the on all four resource of resource R (n+7) existing in the idling-resource of sub-frame of uplink n+k with described sub-frame of uplink n+7 in step a19, explanation can consider according to resource R (n+7) simultaneously dispatching uplink subframe n+k and n+7 to carry out multiframe scheduling.

Step a21, judgement D _trans1whether be greater than D _trans2;

If D _trans1be greater than D _trans2, according to resource R (n+k) while dispatching uplink subframe n+k and n+7, the multiframe scheduling of execution step a23; If D _trans1be less than D _trans2, according to resource R (n+7) dispatching uplink subframe n+k and n+7, the multiframe scheduling of execution step a23; If D _trans1equal D _trans2, according to resource R (n+k) or R (n+7) dispatching uplink subframe n+k and n+7, the multiframe scheduling of execution step a23.

When judging according to resource R (n+k) and resource R (n+7), all can carry out multiframe when scheduling, further judge that the first biography data volume which resource carries is larger, then adopt the large resource of first biography data volume of carrying to carry out multiframe scheduling.

Step a22, fill order's frame scheduling;

Concrete, this step comprises:

When sub-frame of uplink n+k meets the condition of fill order's frame scheduling, foundation is Resources allocation R (n+k) dispatching uplink subframe n+k;

When sub-frame of uplink n+7 meets the condition of fill order's frame scheduling, foundation is Resources allocation R (n+7) dispatching uplink subframe n+7.

Step a23, carries out multiframe scheduling.

Concrete, this step comprises:

More described D _trans1and D _trans2size;

Work as D _trans1be greater than D _trans2time, foundation is Resources allocation R (n+k) dispatching uplink subframe n+k and sub-frame of uplink n+7;

Work as D _trans1be less than D _trans2time, foundation is Resources allocation R (n+7) dispatching uplink subframe n+k and sub-frame of uplink n+7;

Work as D _trans1equal D _trans2time, foundation is Resources allocation R (n+k) or R (n+7) dispatching uplink subframe n+k and sub-frame of uplink n+7.

What the embodiment of the present application was used for first biography data acquisition is a kind of method of passive use multiframe scheduling, when if fill order's frame scheduling can carry whole data to be transferred amount, or fill order's frame scheduling can not carry whole data to be transferred amounts, but carrying out multiframe dispatches while there is the larger wasting of resources, or while carrying out multiframe scheduling, in the idling-resource of a sub-frame of uplink, there is not the on all four resource of Resources allocation of another sub-frame of uplink, or the data volume that fill order's frame scheduling can carry is dispatched when many than carrying out multiframe, does not use multiframe scheduling.The benefit of passive use multiframe scheduling is that can reduce to a certain extent on the one hand base station processes complexity, on the one hand, selects more the superior of Deta bearer ability all the time in single frames scheduling and multiframe scheduling, thereby can optimization system performance.

As shown in Figure 7, be the re-transmission flow chart described in the present embodiment two, described re-transmission flow process specifically comprises the following steps:

Step b1, judges whether sub-frame of uplink n+k and sub-frame of uplink n+7 include data retransmission;

If so, perform step b2; If not, scheduling comprises that the sub-frame of uplink of data retransmission performs step the single frames scheduling of b16.

Owing to carrying out multiframe scheduling, two sub-frame of uplink that are scheduled share identical data indication signaling NDI, therefore, in the present embodiment, only have when sub-frame of uplink n+k and sub-frame of uplink n+7 include data retransmission, just consider that carrying out multiframe dispatches.If two sub-frame of uplink include data retransmission, further carry out the judgement of following process, determine fill order's frame scheduling or multiframe scheduling.

Step b2, in sub-frame of uplink n+k Resources allocation, and resource allocation identification is set is false;

First, be sub-frame of uplink n+k Resources allocation, the resource of distributing is PUSCH, PUSCH is used for carrying described data retransmission.

And in the present embodiment, be also provided with resource allocation identification AllocFlag, the value of described resource allocation identification is false or true.When sub-frame of uplink n+k and the sub-frame of uplink n+7 condition that all satisfied execution multiframe is dispatched, according to the value of AllocFlag, determine how to process, detailed process will be introduced in step below in detail.

Step b3, judges whether successful the resource of sub-frame of uplink n+k distributes;

If so, perform step b4, if not, perform step b7.

The resource of sub-frame of uplink n+k is allocated successfully if, and explanation can consider to carry out according to the resource of distributing for sub-frame of uplink n+k the scheduling process of sub-frame of uplink, otherwise explanation can not be carried out according to the resource of distributing for sub-frame of uplink n+k the scheduling process of sub-frame of uplink.

But after resource is allocated successfully, concrete fill order's frame scheduling or multiframe scheduling, also will further carry out following process and judge.

Step b4, being recorded as the resource that sub-frame of uplink n+k distributes is R (n+k), and resource allocation identification is set is true;

Step b5, judges the on all four resource of resource R (n+k) whether existing in the idling-resource of sub-frame of uplink n+7 with sub-frame of uplink n+k;

If so, perform step b6, if not, perform step b7.

In step b3, judge after resource for sub-frame of uplink n+k is allocated successfully, explanation can be according to resource (n+k) operation dispatching process, but whether can carry out multiframe scheduling according to resource (n+k), also need further to meet the condition in this step b5.

Owing to carrying out multiframe scheduling, the relevant field in DCI format0 can not be respectively two resources that the sub-frame allocation that is scheduled is different, thereby needs to guarantee that the resource of two sub-frame of uplink being scheduled is in full accord.

Therefore, in this step b5, if judge, in the idling-resource of sub-frame of uplink n+7, there is the on all four resource of resource R (n+k) with described sub-frame of uplink n+k, just may according to resource R (n+k) simultaneously dispatching uplink subframe n+k and n+7 to carry out multiframe scheduling.

Step b6, judges whether the resource R (n+k) of sub-frame of uplink n+k can carry the data retransmission of sub-frame of uplink n+7;

If so, determine and meet the condition of carrying out multiframe scheduling, the multiframe scheduling process of execution step b15, according to resource R (n+k) dispatching uplink subframe n+k and sub-frame of uplink n+7; If not, perform step b7.

After if two conditions in step b3 and step b5 all meet, also need to carry out the deterministic process of this step b6, if this judgement is mainly to determine that the resource R (n+k) according to sub-frame of uplink n+k carries out multiframe scheduling, whether can carry the data retransmission of sub-frame of uplink n+7, in the time can carrying, just can carry out multiframe scheduling, simultaneously dispatching uplink subframe n+k and sub-frame of uplink n+7 according to resource R (n+k).

For example, the resource R (n+k) distributing for sub-frame of uplink n+k is 4PRB (physical Radio Bearer, physical radio carrying), the data volume that this resource can be carried is 800bit, the data retransmission of sub-frame of uplink n+k is 800bit, and the data retransmission of sub-frame of uplink n+7 is 1000bit, because R (n+k) is 4PRB, can only carry the data of 800bit, so it can not carry the data retransmission of sub-frame of uplink n+7.

Step b7, in sub-frame of uplink n+7 Resources allocation;

If distribute unsuccessful for sub-frame of uplink n+k resource, or in the idling-resource of sub-frame of uplink n+7, there is not the on all four resource of resource with sub-frame of uplink n+k, or the resource of sub-frame of uplink n+k can not be carried the data retransmission of sub-frame of uplink n+7, explanation can not be carried out according to the resource R (n+k) of sub-frame of uplink n+k multiframe scheduling.Therefore, judge whether to carry out multiframe scheduling according to the resource of sub-frame of uplink n+7.

Step b8, judges whether successful the resource of sub-frame of uplink n+7 distributes;

If so, perform step b9, if not, perform step b12.

The resource of sub-frame of uplink n+7 is allocated successfully if, and explanation can consider to carry out according to the resource of distributing for sub-frame of uplink n+7 the scheduling process of sub-frame of uplink, otherwise explanation can not be carried out according to the resource of distributing for sub-frame of uplink n+7 the scheduling process of sub-frame of uplink.

Step b9, the resource that is recorded as sub-frame of uplink n+7 distribution is R (n+k);

Step b10, judges the on all four resource of resource R (n+7) whether existing in the idling-resource of sub-frame of uplink n+k with sub-frame of uplink n+7;

If so, perform step b11, if not, perform step b13.

In step b8, judge after resource for sub-frame of uplink n+7 is allocated successfully, explanation can be according to resource (n+7) operation dispatching process, but whether can carry out multiframe scheduling according to resource (n+7), also need further to meet the condition in this step b10.

In this step b10, if judge, in the idling-resource of sub-frame of uplink n+k, there is the on all four resource of resource R (n+7) with described sub-frame of uplink n+7, just may according to resource R (n+7) simultaneously dispatching uplink subframe n+k and n+7 to carry out multiframe scheduling.

Step b11, judges whether the resource R (n+7) of sub-frame of uplink n+7 can carry the data retransmission of sub-frame of uplink n+k;

If so, determine and meet the condition of carrying out multiframe scheduling, the multiframe scheduling process of execution step b15, according to resource R (n+7) dispatching uplink subframe n+k and sub-frame of uplink n+7; If not, perform step b13.

After if two conditions in step b8 and step b10 all meet, also need to carry out the deterministic process of this step b11, if this judgement is mainly to determine that the resource R (n+7) according to sub-frame of uplink carries out multiframe scheduling, whether can carry the data retransmission of sub-frame of uplink n+k, in the time can carrying, just can carry out multiframe scheduling according to resource R (n+7), simultaneously dispatching uplink subframe n+k.

B12, judges whether resource allocation identification AllocFlag is true;

When distributing for sub-frame of uplink n+7 resource when unsuccessful, judge whether resource allocation identification AllocFlag is true.If so, illustrate for sub-frame of uplink n+k resource and be allocated successfully, the single frames scheduling process of execution step b16, according to resource R (n+k) the dispatching uplink subframe n+k of sub-frame of uplink; If not, the resource that is illustrated as sub-frame of uplink n+k and sub-frame of uplink n+7 is distributed all failures, therefore, can not be this user equipment allocation resource, cannot carry out the scheduling process of sub-frame of uplink.

Step b13, judges whether described resource allocation identification AllocFlag is true;

If so, perform step b14, if not, perform step the single frames scheduling of b16, according to resource R (n+7) the dispatching uplink subframe n+7 of sub-frame of uplink n+7.

After being allocated successfully for sub-frame of uplink n+7 resource, if there is not the on all four resource of resource R (n+7) with sub-frame of uplink n+7 in the idling-resource of sub-frame of uplink n+k, or when the resource of sub-frame of uplink n+k can not be carried the data retransmission of sub-frame of uplink n+7, explanation explanation can not be carried out according to the resource R (n+7) of sub-frame of uplink n+7 multiframe scheduling; And above-mentioned also judging can not be carried out according to the resource R (n+k) of sub-frame of uplink n+k multiframe scheduling (because only in the time can not carrying out multiframe scheduling according to the resource R (n+k) of sub-frame of uplink n+k, just judge whether to carry out according to the resource R (n+7) of sub-frame of uplink n+7 multiframe scheduling), therefore, can only fill order's frame scheduling.

The concrete resource fill order's frame scheduling for that sub-frame of uplink, also will judge whether described resource allocation identification AllocFlag is true.

When AllocFlag is true, illustrates for sub-frame of uplink n+k resource and be allocated successfully, simultaneously, in step b8, also judge for sub-frame of uplink n+7 resource and be allocated successfully, therefore, further perform step b14, determine the resource fill order's frame scheduling process according to that sub-frame of uplink; When AllocFlag is flase, illustrate for sub-frame of uplink n+k resource, distribute unsuccessful, therefore need to be according to resource R (n+7) the dispatching uplink subframe n+7 of sub-frame of uplink n+7.

Step b14, judges whether number of times that the data retransmission of sub-frame of uplink n+k has retransmitted is more than or equal to the number of times that the data retransmission of sub-frame of uplink n+7 has retransmitted;

If the number of times that the data retransmission of sub-frame of uplink n+k has retransmitted is more than or equal to the number of times that the data retransmission of sub-frame of uplink n+7 has retransmitted, need priority scheduling sub-frame of uplink n+k, therefore, the single frames scheduling process of execution step b16, according to resource R (n+k) the dispatching uplink subframe n+k of sub-frame of uplink n+k; If the number of times that the data retransmission of sub-frame of uplink n+k has retransmitted is less than the number of times that the data retransmission of sub-frame of uplink n+7 has retransmitted, need priority scheduling sub-frame of uplink n+7, therefore, the single frames scheduling process of execution step b16, according to resource R (n+7) the dispatching uplink subframe n+7 of sub-frame of uplink n+7.
