Description

A kind of dispatching method of multi-carrier high-speed upstream packet access
Technical field
The present invention relates to the dispatching technique in mobile communication system, particularly relate to the dispatching method of multi-carrier high-speed upstream packet access (HSUPA).
Background technology
At present, in the dispatching method of the single carrier HSUPA of TD-SCDMA system, base station (NODEB) has a scheduler on each HSUPA carrier wave.Scheduler on each carrier wave is once dispatched in each subframe " n ", by dispatching the UE that HSUPA UE all from this carrier wave, selection is scheduled.In the scheduling of each subframe, scheduler need to be completed following processing:
(1) calculate on this carrier wave each HSUPA UE at the dispatching priority of current subframe " n ".
(2) determine the dispatching priority formation of this carrier wave: according to dispatching priority order from high to low, UE is queued up, the UE that dispatching priority is the highest comes the foremost of formation, and the UE that dispatching priority is minimum comes formation backmost.
(3) determine to be scheduled timing relationship between the E-HICH (strengthening the dedicated channel hybrid automatic repeat request indication channel) of the E-PUCH (enhancing special-channel physical uplink channel) of E-AGCH (strengthening the dedicated channel absolute grant channel), scheduling of scheduling of UE and scheduling: NODEB sends to UE in " n+d1 " subframe with the E-AGCH that dispatches, the E-PUCH that UE sends scheduling in " n+d1+d2 " subframe is to NODEB, and NODEB sends the E-HICH of scheduling to UE in " n+d1+d2+d3 " subframe.Here, d1 represents the timing difference between subframe that subframe that E-AGCH is sent out and scheduler begin to dispatch, and this timing difference is decided by the processing delay of NODEB; D2=2 represents the timing difference between subframe that subframe that E-PUCH is sent out and E-AGCH be sent out, and this timing difference is by the 3GPP standard; D3 represents the timing difference between subframe that subframe that E-HICH is sent out and E-PUCH be sent out, and this timing difference is decided by parameter n E-HICH, the value of this parameter reports RNC after being determined by NODEB, by RNC, this parameter is transmitted to UE, and therefore, NODEB and UE will keep identical E-HICH and the timing relationship between E-PUCH.
(4) determine available E-AGCH on this carrier wave of current subframe.When each subframe scheduling device began to dispatch, all E-AGCH that configure on this carrier wave were available E-AGCH.
(5) determine E-PUCH resource pool at " n+d1+d2 " subframe scheduling.Scheduler need to configure to the resource that the E-PUCH resource pool of NODEB, the non-scheduled E-PUCH of " n+d1+d2 " subframe is taken from RNC and reject, and just obtains the E-PUCH resource pool of " n+d1+d2 " subframe scheduling.
(6) determine the available horsepower of each time slot that the E-PUCH resource pool of " n+d1+d2 " subframe scheduling is occupied.Set in advance the upper limit of the interference power that in occupied each time slot of E-PUCH resource pool of scheduling up channel causes adjacent cell, the upper limit of this interference power can be represented by threshold value PowerTh.The unit of this threshold value is mw.When in the occupied some time slot t of the E-PUCH resource pool of " n+d1+d2 " subframe scheduling, all code channels all belong to the E-PUCH resource pool of this scheduling, the threshold value PowerTh that the available horsepower of this time slot t equals to set in advance.When comprising the non-scheduled E-PUCH of some UE in this time slot t, NODEB need to predict the power of the interference that each UE in these UE causes adjacent cell at time slot t at the non-scheduled E-PUCH of " n+d1+d2 " subframe, and ask the interference power sum of these UE, then cut the available horsepower that this interference power sum just obtains this time slot t from the threshold value PowerTh of time slot t.The available horsepower of the some time slot t that occupy when the E-PUCH resource pool is 0 or less than 0 the time, the E-PUCH resource pool can not be distributed to any UE at each code channel of this time slot.Therefore, when the available horsepower of a time slot t of the E-PUCH resource pool of scheduling is 0 or less than 0 the time, can from the E-PUCH resource pool of scheduling, all channel code of this time slot be rejected.In sum, at each occupied time slot t of E-PUCH resource pool of scheduling, available power resource represents to distribute in this time slot the upper limit of the interference power sum that the E-PUCH of the scheduling of each UE causes adjacent cell.
(7) begin to dispatch one by one each UE according to queue sequence from coming the top UE of dispatching priority formation.After a UE is scheduled, if the UE that is not scheduled in addition in the dispatching priority formation, and old available E-PUCH resource still in the E-PUCH resource pool of old available E-AGCH, scheduling still on this carrier wave just begins the scheduling of next UE in the dispatching priority formation.After a UE is scheduled, if the UE that is not scheduled in the dispatching priority formation does not perhaps have available E-AGCH on this carrier wave, perhaps there is no available E-PUCH resource on this carrier wave, just finish the scheduling of current subframe.When a UE of scheduler schedules, concrete scheduling process is as follows:
Select an E-AGCH from the available E-AGCH of this carrier wave, this E-AGCH must be an E-AGCH during the E-AGCH of this UE gathers, and this selecteed E-AGCH is exactly the E-AGCH of the scheduling of this UE; If on this carrier wave in available E-AGCH neither one E-AGCH be E-AGCH in the E-AGCH set of this UE, to the scheduling failure of this UE.The scheduling of end to this UE begins to dispatch next UE.After successfully being the E-AGCH of UE allocation schedule, carry out following processing.
Select a part of resource as the E-PUCH of the scheduling of this UE from the E-PUCH resource pool of scheduling, determine the code channel that the power mandate of the E-PUCH of this scheduling, time slot that this E-PUCH takies and this E-PUCH take.When distributing E-PUCH to UE, need to distribute according to the HSUPA ability of UE and the SI (schedule information) of UE.According to the HSUPA ability of UE, can determine the maximum number of the E-PUCH time slot that UE can support and the modulation system of support.Distribute to the maximum number of time slot that number of time slot that the E-PUCH of UE takies can not can be supported greater than UE.The SI of UE comprises: TEBS (total E-DCH memory state), HLBS (high priority logic channel memory state), HLID (high priority logic channel ID), UPH (power headroom of UE) and SNPL (Serving cell and adjacent cell path loss ratio).The power mandate of distributing to the E-PUCH of UE can not surpass the maximum power mandate that the UPH of UE can support.And the power of the interference that each time slot at the E-PUCH place of distributing to UE, the E-PUCH of this UE cause adjacent cell can not be greater than the upper limit by the determined interference power of available horsepower of this time slot.Need to use the SNPL of UE during the power of the interference that at each time slot at E-PUCH place, adjacent cell is caused at the E-PUCH that calculates UE.TEBS and HLBS represent respectively the data volume of high priority logic channel in the E-DCH data volume of UE and E-DCH data volume.The modulation system that NODEB supports according to TEBS, HLBS and UE determines to distribute to time interval resource and the code channel resource of the E-PUCH of UE.When NODEB finds: when the E-puch that distributes to UE can't carry the E-DCH data block of minimum (length of minimum E-DCH data block is 23 bits), to the scheduling failure of this UE.When NODEB predicts: when distributing E-PUCH all can't make the signal to noise ratio that is multiplexed into the E-UCCH on E-PUCH be not less than the desired value of E-UCCH signal to noise ratio to UE in any case, to the scheduling failure of this UE.When to the scheduling of a UE failure, finish the scheduling to this UE, begin to dispatch next UE.
The HSUPA ability of UE reports RNC by UE, is transmitted to NODEB by RNC.
In some cases, UE will be triggered SI reporting to NODEB.Trigger the various situations of UE SI reporting and in the situation that every kind of mode that triggers UE SI reporting UE SI reporting sees also relevant 3GPP standard.
UE is not to NODEB in each subframe SI reporting.Between reporting, twice adjacent SI have the unfixed time interval.In interval during this period of time, UE may be scheduled, and may a part of E-DCH data correctly be transferred to NODEB by the E-PUCH of scheduling.Therefore, NODEB need during this period of time according to UE correctly be transferred to it the E-DCH data volume and the E-DCH data volume in the data volume of high priority logic channel upgrade in time TEBS and HLBS.The concrete update method of TEBS and HLBS sees also existing document.
Simultaneously, in interval during this period of time, when being, the wireless channel between UE and NODEB becomes.Become when therefore, the UPH of UE is also.NODEB need to be between adjacent twice SI reports upgrades timely according to the situation of change of the wireless channel UPH to UE.But, do not mention at present the renewal to UPH in document at all.Certainly, in existing document also not to the update method of UPH.
The signal-to-noise target value of E-UCCH sets in advance to NODEB.
If be successfully the E-PUCH of UE allocation schedule, just carry out following processing.
Select an E-HICH as the E-HICH of the scheduling of this UE from the E-HICH set of the scheduling of this UE.
For the UE that is scheduled determines: the E-DCH control information of the upper carrying of E-AGCH, this information are the data of the upper carrying of E-AGCH.
When executing above-mentioned processing, just mean that this UE is successfully dispatched.UE to successfully being dispatched rejects the E-AGCH that distributes to this UE from the available E-AGCH of this carrier wave; The resource that the scheduling E-PUCH of distributing to this UE is used is rejected from the E-PUCH resource pool of the scheduling of this carrier wave; And the available horsepower of upgrading each time slot in the E-PUCH resource pool of dispatching on this carrier wave according to power mandate and the time slot mandate of the E-PUCH that distributes to UE; When the available horsepower resource of a time slot is 0 or less than 0 the time, or when there is no available E-PUCH code channel in this time slot, this time slot is rejected from available E-PUCH resource pool.
(8) after the scheduling of scheduler end in current subframe, the following information of each UE that is successfully dispatched can be handed down to physical layer:
The E-RNTI of this UE
The E-DCH control information of the upper carrying of the ID of the E-AGCH of the scheduling of this UE, subframe number " n+d1 " and E-AGCH.
The subframe number " n+d1+d2 " of the power mandate of the E-PUCH of the scheduling of this UE, time slot mandate and code channel mandate and E-PUCH.
The ID of the E-HICH of the scheduling of this UE and subframe number " n+d1+d2+d3 ".
The physical layer of NODEB will be according to the timing relationship between E-AGCH, E-PUCH and E-HICH, in " n+d1 " subframe, the E-RNTI of E-DCH control information and UE is sent to UE by E-AGCH; Receive in " n+d1+d2 " subframe the E-PUCH that UE sends; Send E-HICH to UE in " n+d1+d2+d3 " subframe.
The below introduces respectively the distribution method of the E-PUCH of the UPH computational methods of computational methods, UE of the dispatching priority of UE in existing document and UE.
The dispatching priority computational methods of UE:
In single carrier HSUPA, the method for calculating the UE dispatching priority is a lot, mainly contains: polling method, maximum traffic rate method and PF (equitable proportion) method etc.
In polling method, UE is queued up according to the time T order from long to short that the UE wait is scheduled in each subframe.Come the top UE of formation, wait for that the time T that is scheduled is the longest; Come the rearmost UE of formation, wait for that the time T that is scheduled is the shortest.Dispatch each UE according to this queue sequence.Whenever a UE is successfully dispatched, this UE waits for that the time T that is scheduled just is initialized to T=0.When a subframe was not scheduled, this UE waited for that the value of the time T that is scheduled just increases by 1, becomes: T=T+1 as this UE.
In the maximum traffic rate method, in each subframe, for each UE, distribute different resources to UE from the E-PUCH resource pool of scheduling, the calculating information bit speed that this UE can transmit under every kind of resource is distributed is distributed from various resources and is selected maximum as the service rate R of this UE the information bit speed that can transmit; Then, the order descending according to service rate R sorts all UE, and the service rate that comes the top UE of formation is maximum, and the service rate that comes the rearmost UE of formation is minimum.According to the order of this formation, from coming top UE, dispatch one by one UE, can make network obtain more maximum up peak rate and larger uplink throughput.
In the PF method, when each subframe scheduling device was dispatched, the dispatching priority factors such as (SPI:Scheduling Priorith Inidacator) of indicating that considers the logic channel of the distribution priority (ARP:Allocation Retention Priority) of MAC-d stream of guaranteed bit rate (Guarented Bit Rate), each UE of Maximum Bit Rate, each UE of service rate R, each UE application of the time T to be scheduled such as each UE, UE and each UE was determined the dispatching priority of each UE.Then, according to dispatching priority order from high to low, UE is queued up, come top UE and begin to dispatch one by one UE from the dispatching priority formation.In the PF method, the dispatching priority computing formula of each UE can be consulted existing document, repeats no more here.
Under single carrier case, UE calculates UPH and the UPH that calculates is reported NODEB according to following formula.
UPH = 10 lg ( P max P e - base · L ) - - - ( 1 )
In following formula, UPH adopts logarithm value, and unit is: dB; P maxThe maximum transmission power of expression UE; P E-baseThe closed power component of being adjusted by the TPC order in expression E-PUCH transmitting power; L represents the path loss of current UE place Serving cell, the ratio of the received power of the PCCPCH that the transmitting power that L equals PCCPCH and UE estimate, and the unit unification of the transmitting power of PCCPCH and the received power of PCCPCH is: mw; P maxAnd P E-baseThe unit unification be: mw.For further illustrating P E-base, with the transmitting power P of E-PUCH E-PUCHComputing formula list in below:
P E-PUCH=P e-base+L+β e (2)
In following formula, P E-PUCHAnd P E-baseRepresent respectively the transmitting power of E-PUCH and the closed power component of E-PUCH, they all adopt logarithm value, and the unit unification is: dBm; L adopts logarithm value, and unit is: dB; β eAdopt logarithm value, unit is: dB.
In following formula: P E-baseAnd β eCan further be expressed as follows:
P e - base = PRX des _ base + step * Σ i TPC i - - - ( 3 )
β e=β 0,eeharq (4)
Wherein, PRX Des_baseThe E-PUCH received power of expression expectation adopts logarithm value, and unit is: dBm is configured to UE by RNC; Step represents power control step-size, and unit is: dB; When the power control commands of i E-PUCH of NODEB feedback is " UP ", TPC iBe 1; When the power control commands of i E-PUCH of NODEB feedback is " DOWN ", TPC iBe-1; β 0, eExpression is adopted logarithm value by the power gain of the code channel of a definite SF=16 of effective code check of E-PUCH, and unit is: dB; α eAdopt logarithm value, value is as shown in the table, and unit is: dB; Δ HarqBe the power bias of HARQ, adopt logarithm value, unit is: dB.

UE will calculate UPH according to the method described above, then look into the mapping relations form between UPH subscript and UPH span in the 3GPP standard, determine the corresponding UPH subscript of UPH value, and this UPH subscript is reported NODEB.NODEB adopts opposite process, and the subscript of the UPH that reports according to UE is looked into the mapping relations form between UPH subscript and UPH span, determines the scope of UPH value, then with the lower limit of the UPH span UPH value as UE.
In single carrier HSUPA, when scheduler has been determined the dispatching priority formation in current subframe " n ", determined available E-AGCH, determined after the available power of each time slot at the E-PUCH resource pool place of the E-PUCH resource pool of " n+d1+d2 " subframe scheduling and scheduling, scheduler needs also to know that following parameter can complete the scheduling in current subframe:
(1) the HSUPA ability of each UE: the modulation system that the maximum number of the E-PUCH time slot that UE can support and UE support.
(2) SI:TEBS of each UE, HLBS, HLID, SNPL and UPH

Represent respectively the P of " n " subframe and " n-m " subframe E-baseRecursive average, adopt linear value, unit is: mw; The E-PUCH of " n-m " subframe is the nearest E-PUCH of E-PUCH that distributes to E-PUCH middle distance " n " subframe of UE before " n " subframe, that is: after " n-m " subframe before " n " subframe, UE is never dispatched by NODEB; The P of expression " n " subframe E-baseEstimated value, unit is: mw; Q=1-v, v are forgetting factors, there is no unit, and span is: v ∈ [0,1], the value of this parameter configures to NODEB.
In the TD-SCDMA system, network can adopt HSDPA and HSUPA usually simultaneously.The Typical Disposition of network is: 2:4, that is: in time slot 1-time slot 6, up 2 time slot: TS1 and the TS2 of comprising descendingly comprises four time slot: TS3-TS6.
Under above-mentioned 2:4 configuration, the E-PUCH resource pool that RNC configures to NODEB includes only a time slot usually.When the E-PUCH resource pool only comprised a time slot t, NODEB was in each subframe " n " when dispatching, and came top UE according to the order of dispatching priority formation from the dispatching priority formation and began to dispatch one by one UE.It is identical giving the process of the E-PUCH of each UE allocation schedule when each UE of scheduling.The method that the below gives the E-PUCH of UE allocation schedule take u UE in " n " subframe scheduling priority query as the example explanation in to the scheduling process of each UE.Here, u UE is the UE that comes u position in the dispatching priority formation, in this UE front, u-1 UE arranged.
At first, distribute to the power mandate β of the E-PUCH of UE at the time slot t of subframe " n " 0, e(n) corresponding β eValue β e(n) should satisfy following formula:
P ^ e - base , av ( n ) + β e ( n ) - SNPL ≤ P t - - - ( 7 )
Wherein, the following formula left side represents the interference that UE causes adjacent cell at the time slot t of subframe " n ", and following formula the right is illustrated in the upper limit of the interference that this residential quarter in the time slot t of subframe " n " adjacent cell is caused, that is: the available horsepower of time slot t; SNPL represents the SNPL of u UE.
Distribute to the power mandate β of UE 0, e(n) corresponding β e(n) also should satisfy following formula:
β e(n)≤UPH (8)
In following formula, UPH represents the UPH value of this UE that SI that NODEB reported according to UE the last time obtains.
Aggregative formula (7) and (8) can obtain: the β that licenses to UE 0, e(n) maximum β 0, e, max(n) corresponding β e(n) maximum β E, max(n) should satisfy following formula:
β e , max ( n ) = min { P t - ( P ^ e - base , av ( n ) - SNPL ) , UPH } - - - ( 9 )
In following formula, min{x, y} represent to get the minimum value in x and y.The SI that UE reports NODEB comprises: the ID of high priority logic channel.The ID of high priority logic channel in the SI that NODEB reported according to UE the last time can determine: corresponding Δ when the HARQ of UE carries data on this high priority logic channel HarqValue, use Δ Harq, maxRepresent this value.
In the E-PUCH of time slot t resource pool, determine the spreading factor that the E-PUCH resource pool of this time slot can use: the spreading factor that the spreading factor that in this time slot, any one available node adopts can use for the E-PUCH resource pool of this time slot.
In the spreading factor that this resource pool can use, optional spreading factor SF E-PUCH, when the spreading factor of the E-PUCH that distributes to UE is SF E-PUCHThe time, tabling look-up 1 can obtain corresponding α eNumerical value α e(n, SF E-PUCH).Here, the spreading factor of distributing to UE is: SF E-PUCH, being equivalent to and distributing to spreading factor of UE is SF E-PUCHChannel code.Distribute to the β of UE 0, e(n) maximum β 0, e, max(n, SF E-PUCH) and the relation of distributing between the spreading factor of E-PUCH of UE as follows:
β 0,e,max(n,SF E-PUCH)=β e,max(n)-Δ harq,maxe(n,SF E-PUCH)(10)
According to above-mentioned formula, the spreading factor that can determine to distribute to UE is SF E-PUCHThe time, the maximum β of the power mandate that UE can obtain at time slot t 0, e, max(n, SF E-PUCH).
According to spreading factor SF E-PUCH, β 0, e, max(n, SF E-PUCH), the signal-to-noise target value SNR of E-UCCH E-UCCHEstimated value with up-to-date E-UCCH signal to noise ratio

Method can consult existing document, be summarized as follows here:
Be located in all E-PUCH subframes of distributing to UE, distance current subframe " n " nearest E-PUCH subframe is subframe " n-m ", and the E-UCCH number that is multiplexed on the E-PUCH of this subframe is N E-UCCH(n-m).According to all N in this subframe E-UCCH(n-m) demodulation result of individual E-UCCH is estimated the mean value SNR of the signal to noise ratio of E-UCCH E-UCCH(n-m).SNR E-UCCH(n-m) estimation repeats no more here referring to existing document.
NODEB is with N E-UCCH(n-m) demodulation result of individual E-UCCH merges, be combined result and carry out E-UCCH decoding, obtain 10 information bits of the upper carrying of E-UCCH: the subscript of the E-DCH data block length that represents with 6 bits, the HARQ ID that represents with 2 bits and the RSN that represents with 2 bits.The subscript of the E-DCH data block length that NODEB represents according to 6 bits can obtain the length of the E-DCH data block of the upper carrying of " n-m " subframe E-PUCH.
NODEB can obtain the power mandate β of this E-PUCH subframe according to the length of the E-DCH data block of the upper carrying of " n-m " subframe E-PUCH 0, e(n-m).NODEB knows the spreading factor of this E-PUCH, and NODEB tables look-up and 1 can determine corresponding α eNumerical value α e(n-m).NODEB can determine the power bias Δ of the HARQ of this subframe according to the logic channel under the E-DCH data of the upper carrying of this subframe E-PUCH Harq(n-m).Therefore, NODEB can obtain the estimated value of E-UCCH signal to noise ratio under up-to-date reference code check reference code road according to the following formula

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
For realizing the dispatching method of multi-carrier HSUPA of the present invention, need UE and NODEB to realize respectively following process:
(1) UE need to realize reporting of SI.For single carrier HSUPA UE, the composition of the SI of this UE and the method for SI reporting see also relevant 3GPP standard.For multi-carrier HSUPA UE, the SI of this UE comprises the SNPL of TEBS, HLBS, HLID, each carrier wave and the UPH of each carrier wave.For multi-carrier HSUPA UE, the computational methods of the SNPL of the TEBS of this UE, HLBS, HLID and each carrier wave are with the computational methods of TEBS, HLBS, HLID and the SNPL of single carrier HSUPA UE.The Square rule of the UPH of each carrier wave of multi-carrier HSUPA UE is still in the middle of research.The present invention will propose the computational methods of three kinds of UPH.The SI that can adopt with single carrier HSUPA UE that reports of the SI of multi-carrier HSUPA UE reports identical method.Because the method is not content of the present invention, repeat no more here.
(2) scheduling of all HSUPA carrier waves in NODEB need to realize the residential quarter in each residential quarter by dispatching method.
NODEB can realize by the method that each carrier wave is independently dispatched the scheduling of each carrier wave in the residential quarter.Under the method, in the residential quarter, each carrier wave has a scheduler, the scheduling of this scheduler all UE on each subframe realizes this carrier wave.In the residential quarter, the scheduling of each carrier wave is separate, parallel carrying out.Under the method, a scheduler can be arranged in the residential quarter, this scheduler is realized the scheduling of all UE on all HSUPA carrier waves in the residential quarter.This scheduler carries out the scheduling of K HSUPA carrier wave serially in each subframe, and the scheduling process of each carrier wave is identical, and is separate.Here, K represents the number of HSUPA carrier wave in the residential quarter.
NODEB can be by each carrier wave the method for combined dispatching realize the scheduling of all UE on all HSUPA carrier waves in the residential quarter.Only have a scheduler under the method in the residential quarter, this scheduler is once dispatched in each subframe, realizes the scheduling to all HSUPA carrier waves in the residential quarter, and this scheduler supports each carrier wave of each multicarrier UE to share the maximum transmission power of UE.
No matter NODEB adopts any in above-mentioned two kinds of dispatching methods, during the scheduling of NODEB UE on realizing each carrier wave, all needs to know the SI of each UE.Whenever the UE SI reporting during to NODEB, in the SI that NODEB just reports with UE, the value of each item of information covers the old value of each item of information of the SI of this UE that NODEB preserves.
Because UE is not each subframe SI reporting, therefore, in the time interval that adjacent twice SI reports, the dispatching method of NODEB need to upgrade in time to TEBS and the HLBS of UE.UPH to UE also will upgrade timely.
Below, the SI of first brief introduction UE reports process.Brief introduction SI report process in introduce three kinds of computational methods of UPH of each carrier wave of multi-carrier HSUPA UE.
Fig. 1 is the SI report flow schematic diagram of UE side of the present invention, and reporting of this SI comprises the steps: as shown in Figure 1
Step 101, subscriber equipment (UE) judge in each subframe: the situation that triggers its SI reporting occurs whether existing in current subframe, if have, execution in step 102, otherwise, UE current subframe not SI reporting to NODEB, re-execute step 101 in next subframe.
Step 102, UE determine the mode in current subframe SI reporting according to described situation.
In this step, UE is according to each situation of its SI reporting of triggering that occurs in current subframe, in the mode (mode 1: by the E-RUCCH SI reporting of two kinds of SI reporting; Mode 2: SI is carried to NODEB by E-PUCH) determine the mode in current subframe SI reporting in.
Each item of information of the SI of step 103, calculating UE, and each groups of information items is dressed up SI.This SI item of information comprises the UPH of each carrier wave.
Step 104, report mode that SI is reported NODEB in current subframe by the SI that determines.Re-execute step 101 in next subframe.
In actual applications, in multi-carrier HSUPA, for UE " u " who supports K carrier wave in the N frequency point cell, for supporting that NODEB dispatches each HSUPA carrier wave of this UE, UE should calculate the UPH of its each HSUPA carrier wave, and reports its UPH on each carrier wave to NODEB.
In step 103, the method for calculating each carrier wave UPH of UE has three kinds.The below provides the computational methods of three kinds of UPH.The first UPH computational methods are calculated UPH from the angle fully compatible with single carrier UPH computational methods.The mapping relations of the second UPH computational methods between the span of the subscript that keeps UPH and UPH as far as possible with single carrier case under on all four angle, calculating UPH.The third UPH computational methods are calculated UPH from the configurable angle of the maximum transmission power of each carrier wave of UE.
The computational methods of the UPH of k the carrier wave that the below reports in the n subframe take " u " individual UE are three kinds of computational methods of example explanation UPH.
Method 1:UE calculates according to the computational methods of single carrier UPH fully at the UPH of n subframe on k carrier wave:
UPH ( u , k , n ) = 10 lg ( P max ( u ) P e - base ( u , k ) · L ( u ) ) - - - ( 17 )
In following formula, the UPH of k the carrier wave that UPH (u, k, n) expression UE " u " reports in the n subframe, unit: dB; P max(u) maximum transmission power of expression UE can not be greater than this maximum transmission power in the transmitting power sum of all carrier waves of any ascending time slot UE; P E-baseThe P of the E-PUCH of UE on k carrier wave of (u, k) expression E-base, when UE calculates UPH, if the E-PUCH on k carrier wave is in open Loop Power control, P E-base(u, k) should equal the E-PUCH received power PRX that this UE expects on k carrier wave Des_base(u, k), when UE calculated UPH, the E-PUCH on k carrier wave was in close-loop power control, P E-base(u, k) should equal the up-to-date P that calculates according to close-loop power controlling method E-baseThe up-to-date path loss estimated value of L (u) expression UE, this path loss estimated value is estimated to obtain by the PCCPCH on main carrier.Further, " u " individual UE is at the transmitting power P of the E-PUCH of n subframe on k carrier wave E-PUCH(u, k, n) calculates according to the following formula:
P E-PUCH(u,k,n)=P e-base(u,k,n)+L(u)+β e(u,k,n)(18)
In following formula: P E-base(u, k, n) and β e(u, k, n) can further be expressed as follows:
P e - base ( u , k , n ) = PRX des - base ( u , k ) + step * Σ i TPC i ( u , k ) - - - ( 19 )
β e(u,k,n)=β 0,e(u,k,n)+α e(u,k,n)+Δ harq(u,k,n) (20)
Wherein, PRX Des_base(u, k) represents u the E-PUCH received power that UE expects on k carrier wave, configured to UE by RNC; Step represents power control step-size, and unit is: dB; When i the power control commands of E-PUCH on k the carrier wave of u UE of NODEB feedback is " UP ", TPC i(u, k) is 1; When i power control commands of NODEB feedback is " DOWN ", TPC i(u, k) is-1; β 0, e(u, k, n) expression is by the power gain of u UE at the definite reference code channel of effective code check of n subframe E-PUCH on k carrier wave, here, and the code channel that reference code one of Dow Jones index spreading factor is SF=16; α e(u, k, n) value such as following table, SF in following table E-PUCHThe spreading factor of E-PUCH on k carrier wave of (u, k, n) expression n subframe; Δ Harq(u, k, n) is the power bias of HARQ on k carrier wave of n subframe.
α e(u, k, n) value and spreading factor SF E-PUCHThe relation of (u, k, n) is as shown in table 2:

Table 2
In above-mentioned UPH definition, P max(u) be the maximum transmission power of a multi-carrier HSUPA UE.For a multi-carrier HSUPA UE who supports K carrier wave, its maximum transmission power P max(u) should be greater than the maximum transmission power of a single carrier HSUPA UE.Therefore, in the definition of above-mentioned UPH, the mapping relations form under different K values between UPH subscript and UPH span need to be defined.When K=1, the mapping relations form between UPH subscript and UPH span is with the mapping relations form between UPH subscript under single carrier case and UPH span.Work as K=2,3,4,5,6 o'clock, the mapping relations form between UPH subscript and UPH span need to be defined.
For avoiding defining K=2, the mapping relations form between 3,4,5,6 o'clock UPH subscripts and UPH span.UPH can adopt following method to realize.
Method two: calculate UPH according to formula (21) in this method:
UPH ( u , k , n ) = 10 lg ( P max ( u ) / K P e - base ( u , k ) · L ( u ) ) - - - ( 21 )
In following formula, K is the number of the HSUPA carrier wave that can support of HSUPA UE, and UE reports by the HSUPA multi-carrier capability this K value is reported RNC, and RNC can be transmitted to NODEB with this K value.
P max(u)/K represents the average transmit power of each carrier wave in multi-carrier HSUPA UE.In the computational methods of the second UPH, if regulation: the average transmit power of this each carrier wave is not more than the maximum transmission power of single carrier HSUPA UE, and on each carrier wave of multi-carrier HSUPA UE, the mapping relations between the span of UPH subscript and UPH will be with the mapping relations between UPH subscript under single carrier and UPH span.NODEB needn't redefine the mapping relations form between UPH subscript and UPH span under multi-carrier HSUPA.
Method three: in this method, allow the maximum transmission power difference of each carrier wave of UE, UPH calculates according to formula (22):
UPH ( u , k , n ) = 10 lg ( P max ( u , k ) P e - base ( u , k ) · L ( u ) ) - - - ( 22 )
In following formula, P maxThe maximum transmission power of k the carrier wave of (u, k) expression UE, this power can be configured to UE by RNC.
As regulation P max(u, k) is not more than the maximum transmission power P of single carrier HSUPA UE maxDuring=24dBm, under the third UPH computational methods, the mapping relations form between UPH subscript and UPH span is with the corresponding form under single carrier case.
If allow P max(u, k) is greater than the maximum transmission power P of single carrier HSUPA UE maxThe time, under the third UPH computational methods, the mapping relations form between UPH subscript and UPH span need to redefine.
The below introduces the dispatching method of NODEB.No matter NODEB adopts the separate dispatching method of each carrier wave still to adopt the dispatching method of each carrier wave combined dispatching, in each subframe, the method that NODEB dispatches on the HSUPA of each residential quarter carrier wave needs to carry out following steps (shown in Figure 2):
Step 201, current subframe " n " to each carrier wave on each item of information of SI of each UE upgrade.
The SI item of information that these are updated comprises: the SNPL of TEBS, HLBS, HLID, each carrier wave and the UPH of each carrier wave.
When current subframe received the SI that a UE reports, the value of each item of information of the SI that NODEB will report with this UE covered the old value of each item of information of this UE that NODEB preserves as NODEB.
When current subframe did not receive the SI that a UE reports, the E-DCH data volume of the correct transmission of E-PUCH by scheduling when NODEB will be scheduled recently according to this UE was upgraded TEBS value and HLBS value as NODEB.Specifically the update method of TEBS and HLB seen also existing document.
To the UPH of each carrier wave of UE, NODEB also needs to upgrade timely.
When the value of each item of information of the SI that reports with this UE covers the old value of each item of information of this UE that NODEB preserves, the old value of the related information items of this UE of SNPL value covering of the TEBS value that can directly report with UE, HLBS value, HLID value, each carrier wave.But, for multi-carrier HSUPA UE, therefore the computational methods that are different from the UPH of single carrier HSUPA UE due to the UPH computational methods of each carrier wave of this UE, need to describe in detail: the method for the real power surplus of definite each carrier wave of UPH value of each carrier wave that reports according to UE.
Below, the UPH that the present invention first introduces each carrier wave that reports according to UE determines the method for true UPH of each carrier wave of UE.Then, introduce at UE during at the SI that current subframe does not report the method that the UPH of each carrier wave of UE is upgraded.
Provided the computational methods of three kinds of UPH in step 103, calculated the method for UPH regardless of the UE place, NODEB needs the subscript of the UPH of each carrier wave of reporting according to UE to determine the real power headroom of each carrier wave.Concrete, definite following three kinds of situations of differentiation that need of the power headroom of each carrier wave of UE are carried out:
Situation one: the maximum transmission power that allows the shared UE of all carrier waves of UE.
In situation once, the maximum transmission power of any one carrier wave of UE can equal the maximum transmission power of UE, but the transmitting power sum of all carrier waves of UE can not be greater than the maximum transmission power of UE in any one ascending time slot of any subframe.
Therefore, in situation once, the real power headroom of each carrier wave of UE is numerically equal to the UPH value of determining according to the first UPH computational methods.
Each carrier wave of situation two: UE is divided equally the maximum transmission power of UE.
Situation two times, the maximum transmission power of each carrier wave of UE equals
Figure G2009100921142D00301
In any one ascending time slot of any subframe the maximum transmission power of each carrier wave of UE can not greater than
Figure G2009100921142D00302
And when there was untapped power in any one ascending time slot of any subframe, this power can not be for using with other carrier waves in time slot with subframe when a carrier wave.
Situation two times, the real power headroom of each carrier wave is numerically equal to the UPH value of determining according to the second UPH computational methods.
Each carrier wave of situation three: UE has maximum transmission power, and the maximum transmission power sum of all carrier waves equals the maximum transmission power of UE.
Situation three times, determined the maximum transmission power of each carrier wave of UE by RNC, and guarantee that the maximum transmission power sum of all carrier waves equals the maximum transmission power of UE.The maximum transmission power of each carrier wave of UE can not be greater than the maximum transmission power of this default carrier wave in any one ascending time slot of any subframe.When there was untapped power in any one ascending time slot of any subframe, this power can not be for using with other carrier waves in time slot with subframe when a carrier wave.
Situation three times, the real power headroom of each carrier wave is numerically equal to the UPH value of determining according to the third UPH define method.
The below provides respectively in above-mentioned three kinds of situations, and NODEB determines the method for real power headroom of each carrier wave of UE.
Situation one:
In situation once, all carrier waves of UE are shared the radio frequency maximum transmission power of UE.The below give respectively artificial situation once NODEB determine the method for real power headroom of each carrier wave of UE according to different UPH computational methods.
Under the first account form of above-mentioned UPH, UE calculates the numerical value of the UPH of carrier wave " k " according to formula (17), then search the mapping relations form between UPH subscript and UPH span under the corresponding K value according to the K value, obtain the subscript of UPH, UE reports NODEB with this subscript.In mapping relations form between UPH subscript and UPH span, lower target span is: 0,1,2 ..., 31, the span of the corresponding UPH of each subscript.
The NODEB side adopts opposite process, looks into according to the UPH subscript of K value and " k " individual carrier wave the span that UPH subscript under the corresponding K value and the mapping relations form between the UPH span obtain the UPH of this carrier wave.NODEB is arranged to the UPH value of the carrier wave " k " of UE the lower limit of UPH span.If that is: NODEB according to K value and the UPH subscript span of determining UPH of tabling look-up is: UPH (u, k, n) ∈ [v1, v2], NODEB arranges the real UPH value of the carrier wave " k " of UE and is: UPH (u, k, n)=v1, the unit of v1 and v2 is: dB.This UPH value is exactly the real power headroom of k the carrier wave of this definite UE of NODEB.
Under the second account form of above-mentioned UPH, UE calculates the numerical value of the UPH of carrier wave " k " according to formula (21), then find the subscript of UPH according to the mapping relations form between UPH subscript under single carrier HSUPA and UPH span, UE reports NODEB with this subscript.
The NODEB side adopts opposite process, obtains the span of the UPH of this carrier wave according to the mapping relations form between UPH subscript and UPH span under the UPH subscript verification certificate carrier wave HSUPA of " k " individual carrier wave.Equally, NODEB is arranged to the UPH value of the carrier wave " k " of UE the lower limit of UPH span.If that is: NODEB according to the UPH subscript span of determining UPH of tabling look-up is: UPH (u, k, n) ∈ [v1, v2], NODEB arranges the UPH value of the carrier wave " k " of UE and is: UPH (u, k, n)=v1, the unit of v1 and v2 is: dB.
Under above-mentioned UPH the second computational methods, NODEB table look-up obtain UPH (u, k, n)=v1 is not the real power headroom of k the carrier wave of this UE.NODEB further need to calculate the real power headroom of the carrier wave " k " of UE according to the following formula:
UPH(u,k,n)=UPH(u,k,n)+10lg(K)(23)
Under the third computational methods of above-mentioned UPH, the maximum transmission power of each carrier wave of UE is configured by RNC, UE calculates the numerical value of the UPH of carrier wave " k " according to formula (22), then look into mapping relations form between UPH subscript and UPH span and find the subscript of UPH, UE reports NODEB with this subscript.
The NODEB side adopts opposite process, looks into according to the UPH subscript of " k " individual carrier wave the span that mapping relations form between UPH subscript and UPH span obtains the UPH of this carrier wave.Equally, NODEB is arranged to the UPH value of the carrier wave " k " of UE the lower limit of UPH span.If that is: NODEB according to the UPH subscript span of determining UPH of tabling look-up is: UPH (u, k, n) ∈ [v1, v2], NODEB arranges the UPH value of the carrier wave " k " of UE and is: UPH (u, k, n)=v1, the unit of v1 and v2 is: dB.
Under the third computational methods of above-mentioned UPH, NODEB table look-up obtain UPH (u, k, n)=v1 is not the real power headroom of k the carrier wave of this UE.NODEB further need to calculate the real power headroom of the carrier wave " k " of UE according to the following formula:
UPH(u,k,n)=UPH(u,k,n)+10lgP max(u)-10lgP max(u,k)(24)
In following formula, the maximum transmission power P of each carrier wave max(u, k) configured to NODEB by RNC.
Situation two:
Situation two times, each carrier wave of UE is divided equally the maximum transmission power of UE.The below gives respectively two times NODEB of artificial situation method of the real power headroom of each carrier wave of definite UE under the first and the second UPH computational methods.Should not adopt the third UPH computational methods two times in situation.
Under the first UPH computational methods, establish the UPH subscript that carrier number K that NODEB supports according to UE and UE report and table look-up definite: the UPH value of the carrier wave of UE " k " is: UPH (u, k, n)=v1.The method of determining in detail of this UPH value is referring to above.The real power headroom of the carrier wave k of UE in situation two calculates according to the following formula:
UPH(u,k,n)=UPH(u,k,n)-10lg(K)(25)
Under the second UPH define method, establish UPH subscript that NODEB reports according to the UE value that obtains UPH of tabling look-up and be: UPH (u, k, n)=v1.This value is exactly the real power surplus of the carrier wave k of UE.The method of determining in detail of this UPH value is referring to above.
Situation three:
Situation three times, the maximum transmission power of each carrier wave of UE is configured by RNC, and the maximum transmission power sum of all carrier waves equals the maximum transmission power of UE.Situation three times, UE should adopt the third UPH computational methods to calculate the UPH of each carrier wave, then looks into the subscript that mapping relations form between UPH subscript and UPH span is found UPH, and UE reports NODEB with this subscript.
The NODEB side adopts opposite process, looks into according to the UPH subscript of " k " individual carrier wave the span that mapping relations form between UPH subscript and UPH span obtains the UPH of this carrier wave.NODEB is arranged to the UPH value of the carrier wave " k " of UE the lower limit of UPH span.That is: UPH (u, k, n)=v1.This value is exactly the real power surplus of k the carrier wave of three times UE of situation.
Here need to prove, in the computing formula of above-mentioned UPH (as formula 17), the maximum transmission power P of UE need to be known in the base station max(u).
The radio frequency maximum transmission power of single carrier UE clear in the 3GPP standard, maximum transmission power and RNC that the maximum transmission power of single carrier UE equals the UE radio frequency configure to the minimum value between the maximum transmission power of UE.
How the radio frequency maximum transmission power of multicarrier UE and maximum transmission power define and there is no regulation.The present invention proposes the method for the radio frequency maximum transmission power of two kinds of definition multicarrier UE, and proposes the method for the maximum transmission power of two kinds of definition multicarrier UE.
The define method 1 of radio frequency maximum transmission power: the radio frequency maximum transmission power of multicarrier UE is divided into several grades.Scope for each grade regulation UE radio-frequency emission power.UE determines the ability rating at own place according to the scope at the radio-frequency emission power place of oneself, the ability rating with radio frequency when UE accesses reports RNC.Method 1 need to be determined the scope of the radio frequency maximum transmission power of the number of ability rating of radio frequency of multicarrier UE and each grade in the 3GPP standard.
The define method 2 of radio frequency maximum transmission power: the RF capabilities of multicarrier UE is directly got by the RF capabilities linear expansion of single carrier UE.Use P RF, maxThe radio frequency maximum transmission power of expression single carrier UE.At present in the 3GPP standard, the radio frequency maximum transmission power P of single carrier UE RF, maxFor: 24dBm.If UE " u " supports a up K carrier wave, the radio frequency maximum transmission power P of UE RF, max(u) be: P RF, max(u)=P RF, max+ 10lgKdBm.
The define method of above-mentioned radio frequency maximum transmission power 2 times, UE only need to report the up-link carrier number K of support, and RNC just knows the radio frequency maximum transmission power of UE.Certainly, UE also can directly report the radio frequency maximum transmission power P of UE RF, max(u) give RNC.
In the computing formula of above-mentioned UPH, need to know the maximum transmission power P of multicarrier UE max(u).This maximum transmission power can equal the radio frequency maximum transmission power of UE.This maximum transmission power also can be got minimum value between the radio frequency maximum transmission power of UE and RNC configure maximum transmission power to UE.
When current subframe does not receive the SI that u UE report, NODEB will upgrade according to following method the UPH of each carrier wave of UE as NODEB.
UE calculates the UPH of each carrier wave of UE according to UPH computational methods mentioned above, and the UPH subscript that this UPH is corresponding reports NODEB.The subscript of the UPH of each carrier wave that NODEB reports according to UE according to method mentioned above is determined the real power headroom of each carrier wave of UE.
Between reporting, adjacent twice UPH of UE have the unfixed time interval.During this period of time, because the wireless channel between UE and NODEB changes, therefore, the corresponding variation will occur with channel in the real UPH value of each carrier wave of UE.Therefore, NODEB needs during this period of time to upgrade timely and accurately according to the variation of channel the real UPH of each carrier wave.Below, introduce the update method of UPH of each carrier wave of the multicarrier UE that the present invention proposes.
Be located at the n subframe, the real power surplus of k the carrier wave of the UE that the subscript of the UPH of the k carrier wave that NODEB reports according to UE obtains according to method mentioned above is: UPH (u, k, n).
In m>n subframe, NODEB will upgrade the power headroom on k the carrier wave of this UE according to the following formula:
UPH ( u , k , m ) = UPH ( u , k , n ) - step * Σ i TPC i ( u , k ) - - - ( 26 )
In following formula, step represents the power control step-size of E-PUCH, and unit is: dB; Before sending from the n subframe to the m subframe during this period of time, when NODEB sends to i the power control commands of E-PUCH of k the carrier wave of this UE to be " UP ", TPC i(u, k) is 1; I the power control commands of E-PUCH of k carrier wave that sends to this UE as NODEB when " DOWN ", TPC i(u, k) is-1.
Step 202, base station are at the SI (this SI comprise the true UPH of each carrier wave of determined UE) of current subframe according to each UE, in the employing residential quarter, the combined scheduling method of all HSUPA carrier waves in the independent scheduling of each HSUPA carrier wave or residential quarter, dispatch described each UE on each HSUPA carrier wave in the residential quarter.
This step is when specific implementation, and according to whether sharing the maximum transmission power of UE between each carrier wave of UE, the dispatching method that this step NODEB is adopted is divided into following two kinds, can adopt any one in these two kinds of methods in the scheduling of each subframe.
The first dispatching method: the independent scheduling of each HSUPA carrier wave in the residential quarter.
Under the method, do not allow the maximum transmission power of the shared UE of all carrier waves of UE, the maximum transmission power of each carrier wave determines, each carrier wave is merely able to use the power of this carrier wave, and the transmitting power of each carrier wave at no time can be greater than the maximum transmission power of this carrier wave.
Under the method, each carrier wave is divided equally the maximum transmission power of UE, is perhaps configured the maximum transmission power of each carrier wave by RNC, and makes the maximum transmission power sum of all carrier waves equal the maximum transmission power of UE.
Under the method, each HSUPA carrier wave can independently be dispatched.Each HSUPA carrier wave can have a scheduler, and this scheduler is realized the scheduling of HSUPA UE on this carrier wave.The scheduling of this carrier wave and the scheduling of other carrier waves are separate.When each carrier wave had a scheduler, in the residential quarter, the scheduling of all carrier waves is parallel carried out.
Under the method, in the residential quarter, all HSUPA carrier waves can arrange a HSUPA scheduler, and this scheduler is realized the scheduling of all HSUPA carrier waves in the residential quarter.In this scheduler, the scheduling of each carrier wave is separate, and serial is carried out.If the residential quarter comprises K HSUPA carrier wave, the scheduling of K HSUPA carrier wave is carried out in the HSUPA scheduler serial of residential quarter.
The second dispatching method: the combined dispatching of all HSUPA carrier waves in the residential quarter
Under the method, for each multi-carrier HSUPA UE, allow the maximum transmission power resource of shared this UE of all carrier waves of this UE.Therefore, a plurality of HSUPA carrier waves of each residential quarter of NODEB side can't be realized independently HSUPA scheduling.In this case, there is a HSUPA scheduler each residential quarter, and this scheduler is realized the combined dispatching of all HSUPA carrier waves in the residential quarter.The HSUPA scheduler of each residential quarter at each subframe scheduling once, determine the UE that is scheduled on each HSUPA carrier wave of this residential quarter, when a UE was dispatched on a plurality of carrier waves simultaneously, the transmitting power sum of this UE on all carrier waves that are scheduled can not be greater than the maximum transmission power of this UE.Under this dispatching method, in the residential quarter, the computational methods of the power headroom of each carrier wave of each HSUPA UE are calculated according to above-mentioned situation method once.
In actual applications, no matter adopt which kind of scheduling mode performing step 202, the base station all needs to determine the dispatching priority of the UE on each carrier wave, and dispatch accordingly according to the descending order of dispatching priority, below a kind of method of determining the dispatching priority of UE based on UPH is proposed in the present invention.
For any one UE on any one HSUPA carrier wave, the transmitting power of the E-PUCH of this UE is calculated according to formula (18).Here, rewrite formula (18) as follows:
P E-PUCH(u,k,n)=P e-base(u,k,n)+L(u)+β e(u,k,n)(18)
Wherein, R ref(u, k, n)=P E-base(u, k, n)+L (u) be with reference under code check with reference to the transmitting power of code channel.With reference to code check be: β 0, eThe corresponding effective code check in (u, k, n)=0; Be 1 code channel that spreading factor is SF=16 with reference to code channel.Below, with P ref(u, k, n) referred to as " with reference under code check with reference to the transmitting power of code channel ".This transmitting power P ref(u, k, n) reflected the channel quality of the E-PUCH of UE.If P ref(u, k, n) becomes large, shows this UE or away from NODEB, perhaps E-PUCH meets with the channel deep fade, and perhaps the interference of E-PUCH place time slot increases; If P ref(u, k, n) diminishes, and shows this UE or close NODEB, and perhaps the E-PUCH channel fading dies down, and perhaps the interference of E-PUCH place time slot diminishes.No matter be that what reason causes P ref(u, k, n) changes, P refThe variation of (u, k, n) has all reflected the channel quality of the E-PUCH of UE.For different UE, P refThe UE that (u, k, n) is little can obtain identical information bit transmission rate with less power under identical E-PUCH resource authorization.Here, identical E-PUCH authorizes and refers to: identical power mandate, identical code channel mandate and identical time slot mandate.
Therefore, can be according to P ref(u, k, n) order is from small to large carried out the dispatching priority sequence with the UE on same carrier wave, with P ref(u, k, n) minimum UE comes the foremost of dispatching priority formation, with P ref(u, k, n) maximum UE comes the dispatching priority formation backmost.According to the UE on this carrier wave of this sequential scheduling, can obtain maximum up peak rate and maximum uplink throughput.
But NODEB does not also know the P of each UE on each carrier wave ref(u, k, n).NODEB is merely able to obtain P by the method for estimating refThe estimated value of (u, k, n).NODEB estimates the P of any one UE on each carrier wave refThe method of (u, k, n) is as follows:
Be located at the n subframe, the real power headroom of k the carrier wave of the UE that the subscript of the UPH of k the carrier wave that NODEB reports according to UE obtains according to method mentioned above is UPH (u, k, n).In the situation that different, the computational methods of the real power surplus of each carrier wave of UE are referring to above.
When NODEB can estimate according to the following formula that UE reports UPH with reference under code check with reference to the transmitting power of code channel
Figure G2009100921142D00371
P ^ ref ( u , k , n ) = 10 lgP - UPH ( u , k , n ) - - - ( 27 )
In following formula, the value of P in above-mentioned situation one, situation two and situation three is different.
In situation one (when all carrier waves that allow UE are shared the maximum transmission power of UE), P=P max(u), when any one carrier wave that this means UE is scheduled, this carrier wave can use all power of UE, and when a carrier wave was not scheduled, the power on this carrier wave can be used by other carrier waves.
In situation two (each carrier wave of UE is divided equally the maximum transmission power of UE), P = P max ( u ) K , When any one carrier wave that this means UE was scheduled, the maximum power that this carrier wave can use was: P = P max ( u ) K , Even some carrier waves of UE are not scheduled, the power on this carrier wave can not be used by other carrier waves.
In situation three (maximum transmission power of each carrier wave of UE is configured by RNC), P=P max(u, k), when any one carrier wave that this means UE is scheduled, the maximum transmission power of this carrier wave can not configure maximum transmission power to this carrier wave greater than RNC.When a carrier wave was not scheduled, the power on this carrier wave can not be used by other carrier waves.
Subframe m afterwards, UE will calculate according to formula (19) P of E-PUCH E-base(u, k, m), therefore, the P of UE ref(u, k, m) will upgrade according to the following formula:
P ^ ref ( u , k , m ) = P ^ ref ( u , k , n ) + step * Σ i TPC i ( u , k ) - - - ( 28 )
With formula (27) substitution following formula, and carry out abbreviation according to formula (26), just can obtain the P of subframe " m " refThe computing formula of (u, k, m) is as follows:
P ^ ref ( u , k , m ) = 10 lgP - UPH ( u , k , m ) - - - ( 29 )
By following formula as can be known: UPH (u, k, m) is less, P ref(u, k, m) is larger; UPH (u, k, m) is larger, P ref(u, k, m) is less.Therefore, according to P ref(u, k, m) order is from small to large carried out dispatching priority sequence to the UE on same carrier wave and is equivalent to according to UPH (u, k, m) order from big to small the UE on same carrier wave is carried out the dispatching priority sequence.
The amount that must calculate due to UPH (u, k, m) when the power mandate of the UE that determines to be scheduled, therefore, with above-mentioned based on P refThe dispatching priority sort method of (u, k, m) is converted into the dispatching priority sort method based on UPH (u, k, m) in realization.Particularly, as follows based on the dispatching priority sort method of UPH:
In the m subframe, upper all UE of carrier wave k are carried out the dispatching priority sequence according to UPH order from big to small, the UE of UPH maximum is come the foremost of dispatching priority formation, the UE of UPH minimum is come the dispatching priority formation backmost.According to the UE on this carrier wave of this sequential scheduling, can obtain maximum up peak rate and maximum uplink throughput.
In above-mentioned dispatching priority sort method based on UPH, when a UE is not scheduled in longer a period of time T, and during T>=GAP, UE first subframe " n " after scheduling interval will adopt open-loop power control method to determine the transmitting power of E-PUCH, here, GAP refers to the GAP in the ULPC of E-PUCH.This rating formula is as follows:
P E-PUCH(u,k,n)=PRX des_base(u,k)+L(u)+β e(u,k,n)(30)
The UPH corresponding with this open loop power may have more differently with the UPH of last subframe " m " before the interval, and is not known to NODEB.
Different for the real UPH of the UPH that avoids a known carrier wave of NODEB and this this carrier wave of UE, and avoid NODEB the situation of the UPH that treats scheduling carrier wave of UE to occur knowing when scheduling, need to do following regulation:
(1) be not scheduled when longer a period of time of UE, and at up-to-date UPH that UE during this period of time calculates and the difference between the last UE UPH that UE calculates when being scheduled | Δ UPH (j, k, m) | during greater than default threshold value TH, UE need to report up-to-date UPH to NODEB.The absolute value of the difference of the UPH that when Δ UPH (j, k, m) is scheduled with the last time for up-to-date UPH, UE calculates.Unit: dB.The unit of TH is: dB, the value of this parameter configures to UE, can be configured to UE by RNC, also can be used as a parameter of UE inside.
(2) calculate if UE finds PRRI, the CRRI and the TRRI that license to the E-PUCH on its each carrier wave according to NODEB: in the time slot at some E-PUCH place, this time slot, the transmitting power sum of all up channels is greater than the maximum transmission power P of UE max(u) time, UE need to report up-to-date UPH to NODEB.
According to afore mentioned rules, the up-to-date UPH of UE by each carrier wave of active reporting is with the situation that different situations appears in UPH and NODEB can't know the UPH that treats scheduling carrier wave of each carrier wave of avoiding UE and NODEB and safeguarding.Under afore mentioned rules, the UPH of each carrier wave of each UE that NODEB safeguards will be accurately.Therefore, carry out the different and appearance of the real UPH of UPH and each carrier wave of UE side of each carrier wave of each UE that the dispatching priority sequence can not safeguard because of NODEB based on the problem of the degradation of the dispatching priority computational methods of UPH based on the UPH of each UE on each carrier wave.
On above-mentioned each carrier wave, the dispatching priority computational methods of HSUPA UE both had been applicable to single carrier HSUPA system and also had been applicable to the multi-carrier HSUPA system.
No matter NODEB adopts above-mentioned which kind of dispatching method, NODEB needs to calculate on each carrier wave the available horsepower of each time slot in the E-PUCH resource pool, and at present, in the E-PUCH resource pool during available horsepower of any one time slot t, only considered to be positioned at the non-scheduled E-PUCH of this time slot of this carrier wave t to the impact of the available horsepower of this time slot of this carrier wave t on calculating each carrier wave.In this time slot of this carrier wave, other up channels all have been left in the basket on the impact of the available horsepower of time slot t.May cause like this: in some subframes, some time slot t at E-PUCH resource pool place on any one carrier wave, the interference power sum that all up channels cause adjacent cell in this time slot of this carrier wave makes this carrier wave uncontrollable to the interference that adjacent cell causes in this time slot greater than the interference threshold PoweTh that sets in advance.The interference that adjacent cell is caused in this this time slot of this carrier wave is uncontrollable has run counter to the controlled principle of uplink interference in HSUPA.Therefore, the present invention proposes: the power that need to consider the interference that in this time slot of this carrier wave, every other up channel causes on determining any one carrier wave during the available horsepower of any one time slot t at E-PUCH resource pool place.Here, every other up channel refers to the up channel except the E-PUCH of scheduling, may comprise: non-scheduled E-PUCH, UL DPCH (uplink special physical channel) and HS-SICH (high-speed shared information channel).
Particularly, the present invention proposes: the time slot t for any one E-PUCH resource pool place on any one carrier wave, check on this carrier wave have which up channel at the time slot t of " n+d1+d2 " subframe.For any one the up channel ch except the E-PUCH of scheduling, NODEB can determine which UE this up channel belongs in these up channels.If this UE has non-scheduled E-PUCH or the E-PUCH of scheduling, this UE necessarily reports SNPL to NODEB.NODEB can predict according to the up-to-date SNPL that this UE reports the power of the interference that this up channel ch causes adjacent cell at the time slot t of " n+d1+d2 " subframe of this carrier wave.If this UE does not have non-scheduled E-PUCH and do not have the E-PUCH of scheduling yet, this UE will can not report SNPL to NODEB.In this case, the NODEB SNPL that can report according to UE is the power that default value SNPL=0 predicts the interference that this up channel ch causes adjacent cell at the time slot t of " n+d1+d2 " subframe of this carrier wave.
In this time slot of this subframe of this carrier wave, ask the interference power sum of the every other up channel except the E-PUCH of scheduling, deduct this interference power sum from the interference threshold of this this time slot of subframe of this carrier wave, just obtain the available horsepower of this time slot of this subframe of this carrier wave t.
How to predict that the interference of E-PUCH non-scheduled on a carrier wave can consult existing document.Below, the present invention provides: the method for predicting on a carrier wave except non-scheduled E-PUCH the interference power of any one other up channel ch.Here, other up channels may comprise: UL DPCH (uplink special physical channel) and HS-SICH (high-speed shared information channel).
Step 1: according to this up channel on this carrier wave on this carrier wave of reception Signal estimation of a nearest subframe this up channel at the received power Power of this subframe (ch, m).Power (ch, m) represents that on this carrier wave, this up channel ch is in the received power of nearest subframe " m ", and unit is: dBm or mw.Not content of the present invention according to the method for the received power of this up channel on this carrier wave of reception Signal estimation of a up channel on a carrier wave, see also pertinent literature, repeat no more here.
Step 2: determine which UE this up channel belongs to, the up-to-date SNPL that reports according to this UE calculates the power P ower (ch, n+d1+d2) of the interference that this up channel on this carrier wave causes adjacent cell at the time slot t of " n+d1+d2 " subframe.
Power(ch,n+d1+d2)=Power(ch,m)-SNPL (31)
In following formula, SNPL is the up-to-date SNPL value of the affiliated UE of this up channel on this carrier wave, and unit is: dB.
When the UE under this up channel on this carrier wave does not report the SNPL value, when calculating following formula, calculate according to SNPL=0dB.
Below by the concrete scheduling process of above-mentioned two kinds of dispatching methods being elaborated the specific implementation of this step.
Adopt the scheduling process of the independent dispatching method of HSUPA carrier wave in the residential quarter:
In this scheduling process, for any one multicarrier UE, all carrier waves of this UE can not be shared the maximum transmission power of this UE, and each carrier wave is merely able to use the power of this carrier wave.
When all carrier waves of UE were divided equally the maximum transmission power of UE, NODEB calculated the real power headroom of each carrier wave of UE according to situation two.
When the maximum transmission power of each carrier wave of UE is configured by RNC, and the maximum transmission power sum of all carrier waves is when equaling the maximum transmission power of UE, and NODEB calculates the real power headroom of each carrier wave of UE according to situation three.
Under this dispatching method, no matter each carrier wave has a scheduler or residential quarter that a scheduler is arranged, and in the residential quarter, the scheduling of each carrier wave is separate.
When the E-PUCH resource pool of RNC configuration includes only a time slot, on each carrier wave, the dispatching method of HSUPA UE is basically identical with the dispatching method of HSUPA UE under single carrier case.Difference is:
(1) in the scheduling of each subframe " n ", NODEB need to estimate in occupied each the time slot t of the E-PUCH resource pool of " n+d1+d2 " subframe scheduling, the interference power of other up channels, and from the interference threshold PoweTh of this time slot t, the interference power of every other up channel in this time slot t is cut the available horsepower that obtains this time slot t.
The single carrier HSUPA scheduler of existing document just in each time slot that the E-PUCH resource pool is occupied the interference of non-scheduled E-PUCH cut from the interference threshold of this time slot, do not consider the interference of other up channels (as: UL DPCH and HS-SICH) except non-scheduled E-PUCH.
(2) can calculate based on UE the dispatching priority of UE on this HSUPA carrier wave at the UPH on this carrier wave.This is the dispatching priority computational methods that the present invention proposes.
(3) when distributing the power mandate of E-PUCH to UE, carry out based on the up-to-date power headroom of UE on this carrier wave and the available horsepower of place time slot.On this carrier wave, the calculating of the power headroom of UE and renewal see also above.
In the scheduling of existing single carrier HSUPA, do not consider the renewal of the UPH of each UE.
When RNC configured E-PUCH resource pool to NODEB and comprises a more than time slot, the present invention proposed the separate dispatching method of all carrier waves in a kind of multi-carrier HSUPA small area.
Under the method in the residential quarter each carrier wave a scheduler can be arranged, realize the scheduling of this carrier wave, the scheduling between each carrier wave is separate.A scheduler can be arranged in each residential quarter under the method, and this scheduler is realized the serial scheduling of all carrier waves in the residential quarter, and the scheduling of each carrier wave is separate.
Under the method, no matter in the residential quarter, each carrier wave has a scheduler or residential quarter that a scheduler is arranged, the scheduling process of each carrier wave is the same, and different is: when each carrier wave had a scheduler, the scheduler on each carrier wave was realized the scheduling to all UE on this carrier wave; The scheduling of all carrier waves is parallel to be carried out; When there is a scheduler residential quarter, carry out serially the scheduling of K carrier wave by this scheduler, realized the scheduling of all UE on any one carrier wave by this scheduler.
The below introduces the separate dispatching method of all carrier waves in a kind of multi-carrier HSUPA small area of the present invention.In this dispatching method, the present invention will introduce the scheduling process of upper all UE of any one carrier wave k in detail.And the scheduling process of being indifferent to this any one carrier wave k is carried out (when each carrier wave has a scheduler) or carried out by the scheduler (when there is a scheduler residential quarter) of this residential quarter by the scheduler on this carrier wave.
The scheduling process of all UE is as follows on any one carrier wave k:
The first step: on carrier wave k, the UE on this carrier wave is being carried out the dispatching priority sequence.Can carry out the dispatching priority sequence based on any one method in the dispatching priority sort method of UPH to the UE on carrier wave k according to what polling method, maximum traffic rate method, PF method and the present invention proposed.
Second step: determine the upper available E-AGCH resource of carrier wave k, determine in the upper scheduling of " n+d1+d2 " subframe carrier wave k the E-PUCH resource pool, determine the available power of each time slot at E-PUCH resource pool place.
Can adopt the mode of form to represent the upper available E-AGCH resource of carrier wave k, the power resource that the E-PUCH resource pool of scheduling and each E-PUCH time slot can be used.But, but be not limited to by form and indicate above-mentioned three kinds of available resources.
Indicate the concrete grammar of above-mentioned three kinds of resources as follows by form:
Be that dimension of k HSUPA carrier wave preservation is: 1 * N K, E-AGCHAvailable E-AGCH form, each element in this form is initialized as: 0.N K, E-AGCHThe number that represents the E-AGCH that configures on k HSUPA carrier wave.J element of this form represents that on k carrier wave, j E-AGCH can use when being " 0 "; J element represents that on k carrier wave, j E-AGCH is unavailable when being " 1 ";
Be that dimension of k HSUPA carrier wave preservation is 31 * N K, TSThe E-PUCH resource pool form of scheduling, N K, TSThe occupied number of time slot of E-PUCH resource pool that represents " n+d1+d2 " subframe scheduling on k carrier wave.The order ascending according to the timeslot number of the occupied time slot of E-PUCH resource pool sorts all E-PUCH time slots, and the time slot of timeslot number minimum is to the 1st row in should form, and the time slot of timeslot number maximum is to last row that should form.Because the span of the corresponding node number of channel code of distributing to E-PUCH is: 0,1,2,3 ..., 31, therefore, the i line display node i-1 of this form.The E-PUCH resource pool form of initialization " n+d1+d2 " subframe scheduling as follows:
T the time slot that occupies at the E-PUCH resource pool if node i is the node that belongs to the E-PUCH resource pool of scheduling, is listed as the t of form that i+1 is capable is initialized as " 0 ", represents that this node can use; If node i is the node that does not belong to the E-PUCH resource pool of scheduling, the t of form is listed as that i+1 is capable is initialized as " 1 ", represent that this node is unavailable.
When all child nodes of a node in time slot t all were " 0 ", this node also was initialized to " 0 ".When in time slot t, a node was initialized to " 0 ", all child nodes of this node were both initialized to " 0 ".
When in time slot t, a node was " 1 ", all father nodes of this node all were initialized as " 1 ", represented that corresponding node is unavailable.
Be that dimension of k HSUPA carrier wave preservation is: 1 * N K, TSAvailable power form, the available power of t the time slot that t element representation E-PUCH resource pool in this form occupies.For the interference that causes to adjacent cell of the transmitting power that makes all UE in upper each the E-PUCH time slot of carrier wave k is controlled in certain limit, can set in advance power threshold PowerTh.The interference power that the transmitting power of any one all UE of E-PUCH time slot of being illustrated in this power threshold causes adjacent cell can not be greater than this threshold value.
T time slot occupying of E-PUCH resource pool for scheduling, if the E-PUCH resource pool of this time slot comprises all nodes in this time slot, show: do not have other up channels at this time slot, t element in above-mentioned power resource form can be initialized as: PowerTh.Up channel except the E-PUCH of scheduling all belongs to other up channels.Other up channels comprise: non-scheduled E-PUCH, UL DPCH and HS-SICH.
If there is the E-PUCH up channel in addition of scheduling in t the time slot at E-PUCH resource pool place, estimate the interference power that the signal of any one up channel in every other up channel causes adjacent cell, and the interference power sum of asking every other up channel that adjacent cell is caused, then from interference threshold PowerTh should and value deduct, with the initialization value of difference as t element in above-mentioned power resource form.
When t element in this form is 0 or less than 0 the time, t time slot of expression E-PUCH resource pool do not have available power, that is: the interference power that the up channel that has existed in this time slot causes adjacent cell has been equal to or greater than the upper limit by the determined interference power of interference threshold PowerTH, can not dispatch any UE again at this time slot.Therefore, when t element is 0 or less than 0 the time, all elements of t row in the E-PUCH resource pool form of scheduling is arranged to " 1 ", represents that this time slot does not have available E-PUCH node.
The 3rd step: the upper the highest UE of dispatching priority of beginning scheduling carrier wave k.Scheduling to this UE comprises following substep:
Step (3-1): optional time slot in the E-PUCH resource pool, selectable combination has N K, TSIn.This UE of scheduling in any one combination.
Be located at above-mentioned N K, TSIn the kind combination, j combination is made of time slot t, j=1, and 2 ..., N K, TSThis UE of scheduling in this combination j.By this UE of scheduling in this combination j, determine whether and can successfully dispatch this UE in combination j, if can successfully dispatch this UE in this combination, determine to license to spreading factor and the corresponding power mandate of this UE.The below simply introduces the method for performing step (3-1).Detailed method introduction sees also the content of background technology part.
At first, distribute to the power mandate β of UE in combination j 0, eMaximum β 0, e, maxCorresponding β eMaximum β E, maxShould satisfy following formula:
β e , max ( n ) = min { P t - ( P ^ e - base , av ( n ) - SNPL ) , UPH } - - - ( M - 1 )
In following formula, P tThe available horsepower of expression time slot t;

The P of UE of being scheduled E-baseThe recursive average of estimated value; SNPL and the UPH UPH of UE of being scheduled on the SNPL of UE and carrier wave k that represents respectively to be scheduled.
In combination j, determine available spreading factor in this combination: the spreading factor that the spreading factor that any one available node adopts in time slot t can be used for this resource pool.
In the available spreading factor of this combination, optional spreading factor SF E-PUCH, when the spreading factor of the E-PUCH that distributes to UE is SF E-PUCHThe time, tabling look-up 1 can obtain corresponding α eNumerical value α e(n, SF E-PUCH).Distribute to the β of UE 0, eMaximum β 0, e, max(n, SF E-PUCH) with distribute to the spreading factor SF of the E-PUCH of UE E-PUCHBetween relation as follows:
β 0,e,max(n,SF E-PUCH)=β e,max(n)-Δ harq,maxe(n,SF E-PUCH)(M-2)
According to above-mentioned formula, the spreading factor that can determine to distribute to UE is SF E-PUCHThe time, UE can obtain the maximum β of power mandate at the indicated time slot t of combination j 0, e, max(n, SF E-PUCH); Δ Harq, maxThe power bias of HARQ during data for UE by the current high priority logic channel of HARQ process carrying.
Can determine that further the power mandate as E-PUCH is β 0, e, max(n, SF E-PUCH) time, be multiplexed into the upward minimal amount N of E-UCCH of this E-PUCH E-UCCH(n, SF E-PUCH).Calculate according to the following formula N E-UCCH(n, SF E-PUCH):
Determine to satisfy the i value of the minimum of following formula, this value is exactly N E-UCCH(n, SF E-PUCH), that is: N E-UCCH(n, SF E-PUCH)=i
x ( i ) ≥ SNR E - UCCH - S N ^ R E - UCCH - ( β 0 , e , max ( n , SF E - PUCH ) + α e ( n , SF E - PUCH ) ) - - - ( M - 3 )
If spreading factor is SF E-PUCHThe time, according to the 3GPP standard be multiplexed into the number of the upper E-UCCH of E-PUCH can be in I value value, this I value is respectively according to order from small to large: N E-UCCH(SF E-PUCH, i), i=1 ..., I, wherein, N E-UCCH(SF E-PUCH, be I) that spreading factor is SF E-PUCHThe time, be multiplexed into the upward maximum number of E-UCCH of E-PUCH.Conclusion is set up:
If by the definite E-UCCH number N of formula (M-3) E-UCCH(n, SF E-PUCH) greater than N E-UCCH(SF E-PUCH, I), can not be with SF E-PUCHLicense to this UE;
If by the definite E-UCCH number N of formula (M-3) E-UCCH(n, SF E-PUCH) equal N E-UCCH(SF E-PUCH, i), can be with SF E-PUCHLicense to this UE, and be SF at the spreading factor that licenses to this UE E-PUCHThe time, the E-UCCH number that is multiplexed on E-PUCH is: N E-UCCH(n, SF E-PUCH)=N E-UCCH(SF E-PUCH, i).
If by the definite E-UCCH number N of formula (M-3) E-UCCH(n, SF E-PUCH) greater than N E-UCCH(SF E-PUCH, i-1), but less than N E-UCCH(SF E-PUCH, i), i≤I can be with SF E-PUCHLicense to this UE, and be SF at the spreading factor that licenses to this UE E-PUCHThe time, the E-UCCH number that is multiplexed on E-PUCH is: N E-UCCH(n, SF E-PUCH)=N E-UCCH(SF E-PUCH, i).
If in combination j, neither one can license to the spreading factor of UE, can't successfully dispatch this UE in this combination j.
If there is at least a spreading factor that can license to UE, in time slot t, determine that each can license to the spreading factor SF of UE E-PUCHThe information bit number N that can transmit Bit(n, SF E-PUCH).N Bit(n, SF E-PUCH) equal 1 spreading factor and equal SF E-PUCHThe code channel bit number that can carry.N Bit(n, SF E-PUCH) computational methods are as follows:
N Bit(n,SF E-PUCH)=max{N QPSK(n,SF E-PUCH),N 16QAM(n,SF E-PUCH)}(M-4)
In following formula,
N QPSK ( n , SF E - PUCH ) = 2 ( N ts · N symbol · 16 SF E - PUCH - 17 N E - UCCH ( n , SF E - PUCH ) ) · λ ( n , SF E - PUCH , QPSK )
N 16 QAM ( n , SF E - PUCH ) = 4 ( N ts · N symbol · 16 SF E - PUCH - 17 N E - UCCH ( n , SF E - PUCH ) ) · λ ( n , SF E - PUCH , 16 QAM )
N tsThe number of time slot that the E-PUCH of UE comprises is distributed in expression, here, and N ts=1; N SymbolThe number of symbols that the code channel of a SF=16 of=44 expressions can carry; N E-UCCH(n, SF E-PUCH) represent that E-PUCH goes up the number of the E-UCCH of carrying; λ (n, SF E-PUCH, QPSK) the expression spreading factor is SF E-PUCH, the mandate of E-PUCH power is β 0, e, max(n, SF E-PUCH), the effective code check the when modulation system that adopts is QPSK, λ (n, SF E-PUCH, 16QAM) the expression spreading factor is SF E-PUCH, the mandate of E-PUCH power is β 0, e, max(n, SF E-PUCH), the effective code check the when modulation system that adopts is 16QAM.For a UE who does not support the 16QAM modulation, there is no need to calculate λ (n, SF E-PUCH, 16QAM).Directly make: N 16QAM(n, SF E-PUCH)=0.
If N Bit(n, SF E-PUCH) during less than 23 bits (minimum length of the upper E-DCH data block of E-PUCH), this spreading factor is deleted from the spreading factor that can license to UE.
If there is no to license to the spreading factor of UE, can't successfully dispatch this UE under this combination.
If the spreading factor that can license to UE is arranged, select spreading factor SF, when the spreading factor of distributing to UE was SF, the information bit number that UE can transmit was maximum in the bit number that all spreading factors can transmit.That is:
Figure G2009100921142D00482
If the bit number that under SF, UE can transmit is not more than the total number of bits SIZE that accumulates in E-DCH memory by the indicated UE of TEBS, when time slot t dispatches this UE with this spreading factor SF and corresponding β 0, e, max(n, SF) licenses to UE.
If the bit number that under SF, UE can transmit greater than the total number of bits SIZE that accumulates in the E-DCH memory by the indicated UE of TEBS, is determined spreading factor SF according to the following formula minWhen dispatching this UE in combination j, with spreading factor SF minWith corresponding β 0, e, max(n, SF min) license to UE.

Kind.Under calculating any one combination in N (k, 2) plants combination, whether can successfully dispatch this UE.If can successfully dispatch this UE, determine to license to spreading factor and the corresponding power mandate of this UE under this combination.If the number of time slot of E-PUCH resource pool is 1, direct execution in step (3-6).
Such as: the number of time slot N of E-PUCH resource pool K, TS=3 o'clock, select arbitrarily wherein two time slots, such combination has: the 3*2/2=3 kind:

If this combination does not exist at two time slots available node all, can not successfully dispatch this UE under this combination.
If exist at least one at two time slots available node all, continue following the processing:
When dispatching this UE in this combination, available power is in these two time slots:
P t = min { P t , P t 1 }
Determine spreading factor available under this combination, and determine according to formula (M-1), (M-2) with (M-3), can license to the spreading factor of UE.
If the neither one spreading factor can license to this UE, can't successfully dispatch this UE under this combination.
If there is at least a spreading factor that can license to UE, determine that each can license to the spreading factor SF of UE E-PUCHThe information bit number N that can transmit Bit(n, SF E-PUCH).N Bit(n, SF E-PUCH) equal at this combination indicated time slot t and t 1, spreading factor is equaled SF E-PUCHA code channel distribute to this UE, during as the E-PUCH of this UE, the bit number N that this E-PUCH can carry Bit(n, SF E-PUCH).Make N ts=2, calculate N according to formula (M-4) Bit(n, SF E-PUCH).If N Bit(n, SF E-PUCH) during less than 23 bits (minimum length of the upper E-DCH data block of E-PUCH), this spreading factor is deleted from the spreading factor that can license to UE.
If there is no to license to the spreading factor of UE, can't successfully dispatch this UE under this combination.
If the spreading factor that can license to UE is arranged, select spreading factor SF according to formula (M-5).
If the bit number N that under SF, UE can transmit Bit(n, SF) is not more than the total number of bits SIZE that accumulates in E-DCH memory by the indicated UE of TEBS, when this UE of this combination dispatching with this spreading factor SF and corresponding β 0, e, max(n, SF) licenses to UE.
If the bit number N that under SF, UE can transmit Bit(n, SF) determines SF according to formula (M-6) greater than the total number of bits SIZE that accumulates in the E-DCH memory by the indicated UE of TEBS min, when this UE of combination " j " dispatching, with spreading factor SF minWith corresponding β 0, e, max(n, SF min) license to UE.
Use SF GrantAnd β 0, e, grantLicense to spreading factor and the corresponding power mandate of UE under the combination " j " that expression is determined according to the method described above.
Step (3-3): if the E-PUCH number of time slot N that the number of time slot of E-PUCH resource pool and this UE support CapacityMinimum value min{N K, TS, N CapacityMore than or equal to 3 o'clock, that is: min{N K, TS, N Capacity} 〉=3 are chosen three time slots wantonly in the E-PUCH resource pool, the combination of this selection has N ( k , 3 ) = N k , TS · ( N k , TS - 1 ) · ( N k , TS - 2 ) 3 ! Kind.Under calculating any one combination in N (k, 3) plants combination, whether can successfully dispatch this UE.If can successfully dispatch this UE, determine to license to spreading factor and the corresponding power mandate of this UE under this combination.If min{N K, TS, N Capacity}<3, direct execution in step (3-6).

If the neither one spreading factor can license to this UE, can't successfully dispatch this UE under this combination.
If there is at least a spreading factor that can license to UE, determine that each can license to the spreading factor SF of UE E-PUCHThe information bit number N that can transmit Bit(n, SF E-PUCH).N Bit(n, SF E-PUCH) equal at this combination indicated time slot t, t 1And t 2, any one can be licensed to the spreading factor SF of UE E-PUCHA corresponding code channel is distributed to this UE, during as the E-PUCH of this UE, and the bit number N that this E-PUCH can carry Bit(n, SF E-PUCH).Make N ts=3, calculate N according to formula (M-4) Bit(n, SF E-PUCH).If N Bit(n, SF E-PUCH) during less than 23 bits (minimum length of the upper E-DCH data block of E-PUCH), this spreading factor SF E-PUCHDeleted from the spreading factor that can license to UE.
If there is no to license to the spreading factor of UE, can't successfully dispatch this UE under this combination.
If the spreading factor that can license to UE is arranged, select spreading factor SF according to formula (M-5).
If the bit number N that under SF, UE can transmit Bit(n, SF) is not more than the total number of bits SIZE that accumulates in E-DCH memory by the indicated UE of TEBS, when time slot t dispatches this UE with this spreading factor SF and corresponding β 0, e, max(n, SF) licenses to UE.
If the bit number N that under SF, UE can transmit BitThe total number of bits SIZE that accumulates in (n, SF) E-DCH memory greater than UE can license in the spreading factor of UE at all, calculates SF according to formula (M-6) minWhen this UE of combination " j " dispatching, with spreading factor SF minWith corresponding β 0, e, max(n, SF min) license to UE.
Use SF GrantAnd β 0, e, grantLicense to spreading factor and the corresponding power mandate of UE under the combination " j " that expression is determined according to the method described above.
Step (3-4): if min{N K, TS, N Capacity} 〉=4 o'clock, optional four time slots in the E-PUCH resource pool, the combination of this selection has N ( k , 4 ) = N k , TS · ( N k , TS - 1 ) · ( N k , TS - 2 ) · ( N k , TS - 3 ) 4 ! Kind.Under calculating any one combination in N (k, 4) plants combination, whether can successfully dispatch this UE.If can successfully dispatch this UE, determine to license to spreading factor and the corresponding power mandate of this UE under this combination.If min{N K, TS, N Capacity}<4, direct execution in step (3-6).
Be located under j combination in the combination of N (k, 4) kind, the number of four time slots in the E-PUCH resource pool that this combination comprises is: t, t 1, t 2And t 3Look into the available horsepower form, the available horsepower of establishing these four time slots is respectively: P t,

With
Figure G2009100921142D00523
At these four time slots, be chosen in all available nodes of these four time slots: in E-PUCH resource pool form, if i is capable t row, t 1Row, t 2Row and t 3When row all are " 0 ", represent that this node " i-1 " is all available at these four time slots.The spreading factor that this node is corresponding is the lower available spreading factor of this combination.
If this combination does not exist at four time slots available node all, can not successfully dispatch this UE under this combination.
If exist at least one at four time slots available node all, continue following the processing:
When dispatching this UE in this combination, available power is in these four time slots:
P t = min { P t , P t 1 , P t 2 , P t 3 }
For this UE, determine available spreading factor under combination.
And determine according to formula (M-1), (M-2) with (M-3), can license to the spreading factor of UE in all available spreading factors.
If the neither one spreading factor can license to this UE, can't successfully dispatch this UE under this combination.
If there is at least a spreading factor that can license to UE, determine that each can license to the spreading factor SF of UE E-PUCHThe information bit number N that can transmit Bit(n, SF E-PUCH).SF E-PUCHEqual at this combination indicated time slot t, t 1, t 2And t 3, spreading factor is equaled SF E-PUCHA code channel distribute to this UE, during as the E-PUCH of this UE, the bit number N that this E-PUCH can carry Bit(n, SF E-PUCH).Use SF E-PUCHRepresent that any one can license to the spreading factor of UE, makes N ts=4, calculate N according to formula (M-4) Bit(n, SF E-PUCH).If N Bit(n, SF E-PUCH) during less than 23 bits (minimum length of the upper E-DCH data block of E-PUCH), this spreading factor SF E-PUCHDeleted from the spreading factor that can license to UE.
If there is no to license to the spreading factor of UE, can't successfully dispatch this UE under this combination.
If the spreading factor that can license to UE is arranged, select spreading factor SF according to formula (M-5).
If the bit number N that under SF, UE can transmit Bit(n, SF) is not more than the total number of bits SIZE that accumulates in the E-DCH memory of UE, combination j when dispatching this UE with this spreading factor SF and corresponding β 0, e, max(n, SF) licenses to UE.
If the bit number N that under SF, UE can transmit BitThe total number of bits SIZE that accumulates in (n, SF) total E-DCH memory greater than UE determines spreading factor SF according to formula (M-6) minWhen this UE of combination " j " dispatching, with spreading factor SF minWith corresponding β 0, e, max(n, SF min) license to UE.
Use SF GrantAnd β 0, e, grantLicense to spreading factor and the corresponding power mandate of UE under the combination " j " that expression is determined according to the method described above.
Step (3-5): if min{N K, TS, N Capacity}=5 are determined: in the situation that distribute to whole 5 time slots that the E-PUCH of UE comprises the E-PUCH resource pool, whether can successfully dispatch this UE, if can successfully dispatch this UE, determine to license to spreading factor and the corresponding power mandate of this UE.If min{N K, TS, N Capacity}<5, direct execution in step (3-6).
Look into the available horsepower form, can obtain to be respectively in the available horsepower of 5 time slots of first time slot to the of E-PUCH resource pool: t, t 1, t 2, t 3And t 4
At these five time slots, be chosen in all available nodes of these five time slots: in E-PUCH resource pool form, if when the 1st capable row of i all are " 0 " to the 5th row, represent that this node " i-1 " is all available at these five time slots.The spreading factor that this node is corresponding is available spreading factor.
If there is no at five time slots available node all, comprise 5 time slot situations at the E-PUCH that distributes to UE, can't successfully dispatch this UE.
If exist at least one at five time slots available node all, continue following the processing:
The power that can use when determining to dispatch this UE simultaneously in five time slots:
P t = min { P t , P t 1 , P t 2 , P t 3 , P t 4 }
For this UE, determine the spreading factor that to use when all time slots.
And determine according to formula (M-1), (M-2) with (M-3): the spreading factor that can license to UE.
If the neither one spreading factor can license to this UE, can't successfully dispatch this UE.
If there is at least a spreading factor that can license to UE, determine that each can license to the spreading factor SF of UE E-PUCHThe information bit number N that can transmit Bit(n, SF E-PUCH).N Bit(n, SF E-PUCH) equal any one time slot in 5 time slots that resource pool comprises, spreading factor is equaled SF E-PUCHA code channel distribute to this UE, during as the E-PUCH of this UE, the bit number N that this E-PUCH can carry Bit(n, SF E-PUCH).Make N ts=5, calculate N according to formula (M-4) Bit(n, SF E-PUCH).If N Bit(n, SF E-PUCH) during less than 23 bits (minimum length of the upper E-DCH data block of E-PUCH), this spreading factor SF E-PUCHDeleted from the spreading factor that can license to UE.
If there is no to license to the spreading factor of UE, can't successfully dispatch this UE under this combination.
If have in the spreading factor that can license to UE, select spreading factor SF according to formula (M-5).
If the bit number N that under SF, UE can transmit Bit(n, SF) is not more than the total number of bits SIZE that accumulates in the E-DCH memory of UE, when time slot t dispatches this UE with this spreading factor SF and corresponding β 0, e, max(n, SF) licenses to UE.
If the bit number N that under SF, UE can transmit BitThe total number of bits SIZE that accumulates in (n, SF) E-DCH memory greater than UE determines SF according to formula (M-6) minWith this spreading factor SF minWith corresponding β 0, e, max(n, SF min) license to UE.
Use SF GrantAnd β 0, e, grantThe spreading factor that licenses to UE that expression is determined according to the method described above and corresponding power mandate β 0, e, max
Step (3-6): the E-PUCH that determines to distribute to UE.
For a UE, determine that according to above-mentioned substep (3-1)-substep (3-5) all can successfully dispatch the combination of this UE.If neither one can successfully be dispatched the combination of this UE, to the scheduling failure of this UE, begin to dispatch next UE.If there is at least the combination that can successfully dispatch this UE, in all can successfully dispatch the combination of this UE, select a combination, the bit number that the lower UE of this combination can transmit is the maximum in all combinations.If the bit number that this combination can be transmitted is not more than the total number of bits SIZE that the E-DCH memory of UE accumulates, this combination is exactly the combination that is scheduled.
If the total number of bits SIZE that the bit number that this combination can be transmitted accumulates greater than the E-DCH memory of UE, just need to reselect a combination, system of selection is: in all combinations, the combination of a transmitted bit number minimum is selected in the combination of the total number of bits SIZE that accumulates in the E-DCH memory of the bit number that selection can be transmitted more than or equal to UE in these combinations.This combination is exactly the combination that is scheduled.
After having determined the combination that is scheduled, at this UE of this combination dispatching, and will make up down the SF that determines GrantAnd β 0, e, grantDistribute to the E-PUCH of this UE.The E-PUCH method of concrete definite UE is as follows:
Each time slot that this combination comprises is distributed to the E-PUCH of UE; The lower β that determines of this combination 0, e, grantDistribute to UE, as the power mandate of the E-PUCH of UE; Under this combination, the spreading factor of distributing to the E-PUCH of UE is SF GrantAll time slots that are chosen in this combination are available node all, and selecting spreading factor in these enabled nodes is SF GrantNode as the node of the E-PUCH of this UE; If spreading factor is SF GrantNode not unique, select a disabled node of father node to distribute to the E-PUCH of UE in these nodes; If the disabled node of father node is not unique, select at random a node to distribute to the E-PUCH of UE.
Step (3-7): when successfully dispatching this UE, the E-AGCH that this UE is occupied is arranged to unavailable, the resource that the E-PUCH that distributes to this UE is occupied is arranged to unavailable, and the interference that the power mandate of distributing to this UE is caused cuts from the interference margins of each time slot.
Step 4: after a UE is scheduled, if the UE that is not scheduled in addition in the dispatching priority formation, and old available E-PUCH resource still in the E-PUCH resource pool of old available E-AGCH, scheduling still on this carrier wave just begins the scheduling of next UE in the dispatching priority formation.After a UE is scheduled, if the UE that is not scheduled in the dispatching priority formation does not perhaps have available E-AGCH on this carrier wave, perhaps there is no available E-PUCH resource on this carrier wave, just finish the scheduling of current subframe.To the scheduling of each UE referring to step 3.
Adopt the scheduling process of the combined scheduling method of all HSUPA carrier waves in the residential quarter as follows:
In NODEB the scheduler of each residential quarter in each subframe " n " to the residential quarter in all UE on all HSUPA carrier waves carry out combined dispatching.If N carrier wave arranged in the residential quarter, comprising K HSUPA carrier wave.At each subframe " n ", the scheduling process of scheduler is as follows:
The first step: on each HSUPA carrier wave, the UE on this carrier wave is carried out the dispatching priority sequence.This step is with the first step of each carrier wave independence dispatching method.
Second step: determine E-AGCH resource available on each carrier wave, determine at " n+d1+d2 " subframe scheduling the E-PUCH resource pool, determine the power resource that each E-PUCH time slot can be used.This step is with the second step of each carrier wave independence dispatching method.
The 3rd step: from any one carrier wave, begin to dispatch the highest UE of priority on each carrier wave.Without loss of generality, since the 1st HSUPA carrier wave, dispatch the top UE of dispatching priority formation that comes this carrier wave on the 1st carrier wave.If this UE is u 1Individual UE.u 11,2 ..., value in U.U represents the number of HSUPA UE in this residential quarter.Do not comprise k carrier wave if distribute to the HSUPA carrier wave of a HSUPA UE, will not comprise this UE in the dispatching priority formation of this carrier wave.
If in the dispatching priority formation, there is j-1 UE the front of a UE, and the position of this UE is j.If the position of this UE in the dispatching priority formation of a carrier wave is j1, the position in the dispatching priority formation of another carrier wave is j2, when j1<j2, lags behind the position of j1 with regard to the position that represents j2; When j1=j2, represent that the position in the dispatching priority formation of this UE on corresponding two carrier waves is identical.
During dispatching priority is the highest on first carrier wave UE, determine this UE of scheduling on which carrier wave according to following method.
If (1-1) this UE only supports this carrier wave (that is: UE only supports 1 HSUPA carrier wave), determine this UE of scheduling on this carrier wave;
If (1-2) this UE supports 1<M 1≤ K HSUPA carrier wave investigated this UE at other M 1This UE of scheduling on the 1st carrier wave if the position of this UE in the dispatching priority formation of other carrier waves all lags behind the position of this UE in the dispatching priority formation of the 1st carrier wave, is determined in position in the dispatching priority formation of-1 carrier wave.
If (1-3) at other M 1There is m in-1 carrier wave 1>0 carrier wave, this UE is at this m 1Position on individual carrier wave is identical with the position of this UE on the 1st carrier wave, and NODEB need to be according to certain criterion this m with this UE 1+ 1 carrier wave carries out prioritization.Then begin this UE of scheduling of carrier wave one by one from the highest carrier wave of priority.
This m 1The prioritization criterion of+1 carrier wave can adopt any one in following two kinds of criterions:
(1) according to the descending order of the UPH of this UE on these carrier waves, with the sequence of these carrier waves, begin this UE of scheduling of carrier wave one by one from the carrier wave of UPH maximum.
(2) respectively at this m 1On+1 carrier wave, this UE of scheduling, determine at this m 1In+1 carrier wave during this UE of the upper scheduling of any one carrier wave " k ", distribute to the information bit quantity that the E-PUCH of this UE can carry.Information bit quantity order from big to small according to each carriers carry sorts these carrier waves.Then begin this UE of scheduling of carrier wave one by one from the carrier wave that makes number one.
In criterion 2, at this UE of the upper scheduling of any one carrier wave " k ", when the E-PUCH resource pool on this carrier wave includes only a time slot, the information bit number that in the time of can fully determining to dispatch this UE on this carrier wave according to the dispatching method of single carrier HSUPA in prior art, UE can carry; When the E-PUCH resource pool on this carrier wave comprises a more than time slot, the information bit number that in the time of can adopting method that each carrier wave that the present invention proposes is independently dispatched to determine this UE of scheduling on this carrier wave, UE can carry.At this m 1The information bit that in+1 carrier wave, this UE can carry during this UE of the upper scheduling of any one carrier wave k keeps count of and calculates according to formula (M-1)-(M-5).
When according to any one in above-mentioned criterion with m 1After the sequence of+1 carrier wave, in order one by one during this UE of the scheduling of carrier wave, if when successfully dispatching this UE on a carrier wave, just the station location marker with the priority query at this UE place on this carrier wave becomes " successfully dispatching "; If on a carrier wave during this UE of scheduling failure, just with the station location marker one-tenth " dispatching unsuccessfully " of the priority query at this UE place on this carrier wave.
When completing after this UE of scheduling on a carrier wave, if this UE does not have remaining power resource, the station location marker one-tenth " can't dispatch " at this UE place in the dispatching priority formation of any one carrier wave that is not scheduled in the carrier wave of just this UE being supported.Like this, on the carrier wave that all these UE are not scheduled in the carrier wave that this UE supports, this UE will can not be scheduled again.If this UE has dump power, need to the power headroom of other any one carrier wave that is not scheduled of this UE be upgraded.
When completing after this UE of scheduling on a carrier wave, if do not have in the dispatching priority formation of this carrier wave other etc. UE to be scheduled, perhaps there is no available E-AGCH on this carrier wave, perhaps there is no available E-PUCH resource on this carrier wave, just this carrier identification is become " stopping scheduling ", just do not dispatch any UE in follow-up scheduling process on this carrier wave.If the carrier wave that in the residential quarter, all HSUPA carrier waves are all " stopping scheduling " just finishes the scheduling process at current subframe scheduling device.
As UE " u of scheduling on a carrier wave k 1" time, at first distributing to this UE from the E-AGCH form intermediate value of k carrier wave for E-AGCH of selection the E-AGCH of " 0 ", this E-AGCH one fixes in the E-AGCH set of this UE.
If be worth for neither one E-AGCH in the E-AGCH of " 0 " in the E-AGCH of this UE set, to the scheduling failure of this UE.
After successfully distributing E-AGCH for UE, distribute E-PUCH for this UE from the E-PUCH resource pool form of k carrier wave.When the E-PUCH resource pool comprises a time slot, distribute the method for E-PUCH can adopt the method for distributing E-PUCH in single carrier HSUPA, particular content is referring to the related content of background technology part.When the E-PUCH resource pool comprises a more than time slot, can adopt above " the independent dispatching method of HSUPA carrier wave " to distribute E-PUCH to UE.
After successfully distributing E-PUCH for UE, select an E-HICH as the E-HICH of the scheduling of this UE from the E-HICH set of the scheduling of this UE.
, for distributing E-AGCH, UE after E-PUCH and E-HICH, the E-AGCH that distributes to this UE is rejected from the available E-AGCH of this carrier wave when successfully.Particularly, establish the E-AGCH that distributes to this UE and be j E-AGCH in the E-AGCH form, j element in the E-AGCH form is set to " 1 ", represents unavailable.
Each time slot at the E-PUCH place of distributing to this UE, the E-PUCH Node configuration that will distribute to this UE becomes " unavailable ".Particularly, distributing to the corresponding row of any one time slot " t " of UE in E-PUCH resource pool form, the element of distributing to node " i " corresponding " i+1 " row of UE is arranged to " 1 ", and these all father nodes that are listed as this node are arranged to " 1 ".
In available power form, the available horsepower of distributing to the corresponding row of time slot " t " of UE is updated to by initial value:
P t = P t ( 0 ) - ( P ^ e - base , av ( n ) + β e , grant - SNPL ) - - - ( N - 1 )
In following formula, P t(0) initialization value of t element in expression available horsepower form, work as P tBe 0 or less than 0 o'clock, just all Node configurations with t row in E-PUCH resource pool form become " 1 "; β 0, grantCalculate according to the following formula:
β e,grant=β 0,e,grante(SF grant)+Δ harq,max(N-2)
In following formula, β 0, e, grantThe power mandate of expression E-PUCH; α e(SF Grant) with the spreading factor SF of E-PUCH GrantRelation as shown in table 2; Δ Harq, maxThe power bias of corresponding HARQ during expression HARQ carrying high priority logical channel data.
After successfully dispatching a UE, need the UPH of other carrier waves that are not scheduled of this UE of renewal.
After this UE was dispatched by success rate, the logarithm value of the dump power of this UE was:
P left,dB(u)=10lgP max-(10lgP max-UPH(u,k))-β e,grant(u,k,n)(N-3)
When carrier wave " k ' " when being scheduled, the transmitting power in the reference code check reference code road of this carrier wave is:
P ref(u,k′)=10lgP max-UPH(u,k′)
In following formula, UPH (u, k ') represents the up-to-date power headroom of the individual carrier wave of k ' of this UE.
For carrier wave " k ' ", the value UPH of the UPH of this carrier wave (u, k ') needs to upgrade according to the following formula:
UPH(u,k′)=10lgP left,dB-P ref(u,k′,n)(N-4)
For the highest UE " u of priority on the 1st carrier wave 1", complete at above-mentioned m according to method mentioned above 1After this UE of scheduling, begin in order to dispatch the highest UE of priority query's medium priority on the 2nd carrier wave on+1 carrier wave.If this UE is " u in the residential quarter 2" individual HSUPA UE.Following situation may appear in the scheduling to this UE:
(1) if this UE this carrier wave identified one-tenth " dispatch " or " dispatching unsuccessfully " or " can't dispatch ", just begin the scheduling of the UE that on next carrier wave, priority is the highest.
(2) if this UE is not scheduled, just determine the carrier wave of this UE of scheduling according to method mentioned above on this carrier wave.Specific as follows:
If (1-1) this UE only supports this carrier wave, determine this UE of scheduling on this carrier wave;
If (1-2) this UE supports 1<M 2≤ K HSUPA carrier wave investigated this UE at other M 2This UE of scheduling on the 2nd carrier wave if the position of this UE in the dispatching priority formation of other carrier waves all lags behind the position of this UE in the dispatching priority formation of the 2nd carrier wave, is determined in position in the dispatching priority formation of-1 carrier wave.
If (1-3) at other M 2There is m in-1 carrier wave 2Individual carrier wave, this UE is at this m 2Position on individual carrier wave is identical with the position of this UE on the 2nd carrier wave, and NODEB need to be according to certain criterion this m with this UE 2+ 1 carrier wave carries out prioritization.Then begin this UE of scheduling of carrier wave one by one from the highest carrier wave of priority.
This m 2The prioritization criterion of+1 carrier wave can adopt any one in following two kinds of criterions:
(1) according to the descending order of the UPH of this UE on these carrier waves, with the sequence of these carrier waves, begin this UE of scheduling of carrier wave one by one from the carrier wave of UPH maximum.
(2) respectively at this m 2This UE of scheduling on+1 carrier wave when determining in this M1+1 carrier wave upper this UE of scheduling of any one carrier wave " k ", distributes to the information bit quantity that the E-PUCH of this UE can carry.Information bit quantity order from big to small according to each carriers carry sorts these carrier waves.Then begin this UE of scheduling of carrier wave one by one from the carrier wave that makes number one.
When according to any one in above-mentioned criterion with m 2After the sequence of+1 carrier wave, in order one by one during this UE of the scheduling of carrier wave, if when successfully dispatching this UE on a carrier wave, just the station location marker with the dispatching priority formation at this UE place on this carrier wave becomes " successfully dispatching "; If on a carrier wave during this UE of scheduling failure, just with the station location marker one-tenth " dispatching unsuccessfully " of the dispatching priority formation at this UE place on this carrier wave.
When completing after this UE of scheduling on a carrier wave, if this UE does not have remaining power resource, the station location marker one-tenth " can't dispatch " at this UE place in the dispatching priority formation of any one carrier wave that is not scheduled in the carrier wave of just this UE being supported.Like this, on the carrier wave that all these UE are not scheduled in the carrier wave that this UE supports, this UE will can not be scheduled again.If this UE has dump power, the carrier wave that just need to not be scheduled to any one this UE upgrades the power headroom of this carrier wave.
When completing after this UE of scheduling on a carrier wave, if do not have in the dispatching priority formation of this carrier wave other etc. UE to be scheduled, perhaps there is no available E-AGCH on this carrier wave, perhaps there is no available E-PUCH resource on this carrier wave, just this carrier identification is become " stopping scheduling ", just do not dispatch any UE in follow-up scheduling process on this carrier wave.If the carrier wave that in the residential quarter, all HSUPA carrier waves are all " stopping scheduling " just finishes the scheduling process at current subframe scheduling device.
For the highest UE " u of priority on the 2nd carrier wave 2", the m that completes according to the method described above at this UE 2After this UE of scheduling, just begin to dispatch in order the highest UE of scheduling priority query's medium priority on the 3rd carrier wave on+1 carrier wave.The scheduling process of this UE be please refer to scheduling process to the UE that on the 2nd carrier wave, dispatching priority is the highest.
According to the method described above, complete the 4th, 5 ...., the scheduling of the UE that on K carrier wave, dispatching priority is the highest.The scheduling process of the UE that dispatching priority is the highest on the 2nd carrier wave of dispatching method reference of the UE that on this carrier wave of scheduling on each carrier wave, dispatching priority is the highest.Above-mentioned dispatching method on second carrier wave or the arbitrary carrier wave k (k>1) after it can be summarized as follows:
If this UE has been scheduled or has dispatched failure and maybe can't dispatch begin the scheduling of the UE that on next carrier wave, dispatching priority is the highest at this carrier wave.
If this UE is not scheduled, dispatch this UE, described being scheduling on this carrier wave:
If this UE only supports this carrier wave, dispatch this UE on this carrier wave;
If this UE supports 1<M k≤ K HSUPA carrier wave is if this UE is at other M kPosition in the dispatching priority formation of-1 carrier wave all lags behind the position of this UE in the dispatching priority formation of k carrier wave, determines this UE of scheduling on k carrier wave; If at other M kThere is m in-1 carrier wave kIndividual carrier wave, this UE is at this m kPosition on individual carrier wave is identical with the position of this UE on k carrier wave, and NODEB need to be according to the described m of the second default ranking criteria with this UE k+ 1 carrier wave carries out prioritization; Then begin this UE of scheduling of carrier wave one by one from the highest carrier wave of priority.
Described the second ranking criteria is:
According to this UE at described m kThe order that UPH on+1 carrier wave is descending is with described carrier wave sequence; Be perhaps:
Respectively at described m kOn+1 carrier wave, this UE of scheduling, determine at described m kIn+1 carrier wave during this UE of the upper scheduling of any one carrier wave " k ", distribute to the information bit quantity that the E-PUCH of this UE can carry; Information bit quantity order from big to small according to each carriers carry sorts these carrier waves.
After the scheduling of completing the highest UE of dispatching priority on each carrier wave, not the carrier wave of " stopping scheduling " if having a HSUPA carrier wave at least, just carry out next step; Otherwise, finish the scheduling in current subframe.
The 4th step: the highest UE of dispatching priority on the HSUPA carrier wave of each non-" stopping scheduling " is rejected from the dispatching priority formation of this carrier wave.Like this, the UE that is positioned at the 2nd position in the dispatching priority formation of each carrier wave just becomes the highest UE of dispatching priority on this carrier wave.
The 5th step: begin to dispatch in order the highest UE of dispatching priority on each carrier wave from first carrier wave.If a carrier wave is the carrier wave of " stopping scheduling ", just directly cross this carrier wave, dispatch the highest UE of dispatching priority on next carrier wave.The method of the UE that this carrier dispatching priority of scheduling is the highest on each carrier wave please refer to the method for the UE that in the 3rd step, dispatching priority is the highest on this carrier wave of scheduling on the 2nd carrier wave.Here, the scheduling process of the UE that dispatching priority is the highest on k carrier wave is repeated below:
(1) if this UE this carrier wave identified one-tenth " dispatch " or " dispatching unsuccessfully " or " can't dispatch ", just begin the scheduling of the UE that on next carrier wave, dispatching priority is the highest.
(2) if this UE is not scheduled, just determine this UE of scheduling on which carrier wave according to following method on this carrier wave.
If (2-1) this UE only supports this carrier wave, determine this UE of scheduling on this carrier wave;
If (2-2) this UE supports 1<M k≤ K HSUPA carrier wave investigated this UE at other M kThis UE of scheduling on k carrier wave if the position of this UE in the dispatching priority formation of other carrier waves all lags behind the position in the dispatching priority formation of this UE at k carrier wave, is determined in position in the dispatching priority formation of-1 carrier wave.
If (2-3) at other M kThere is m in-1 carrier wave kIndividual carrier wave, this UE is at this m kPosition on individual carrier wave is identical with the position of this UE on k carrier wave, and NODEB need to be according to certain criterion this m with this UE k+ 1 carrier wave carries out prioritization.Then begin this UE of scheduling of carrier wave one by one from the highest carrier wave of priority.
This m kThe ranking criteria of+1 carrier wave can adopt any one in following two kinds of criterions:
(1) according to the descending order of the UPH of this UE on these carrier waves, with the sequence of these carrier waves, begin this UE of scheduling of carrier wave one by one from the carrier wave of UPH maximum.
(2) respectively at this m kOn+1 carrier wave, this UE of scheduling, determine at this m kIn+1 carrier wave during this UE of the upper scheduling of any one carrier wave " k ", distribute to the information bit quantity that the E-PUCH of this UE can carry.Information bit quantity order from big to small according to each carriers carry sorts these carrier waves.Then begin this UE of scheduling of carrier wave one by one from the carrier wave that makes number one.
When according to any one in above-mentioned criterion with m kAfter the sequence of+1 carrier wave, in order one by one during this UE of the scheduling of carrier wave, if when successfully dispatching this UE on a carrier wave, just the station location marker with the dispatching priority formation at this UE place on this carrier wave becomes " successfully dispatching "; If on a carrier wave during this UE of scheduling failure, just with the station location marker one-tenth " dispatching unsuccessfully " of the dispatching priority formation at this UE place on this carrier wave.
When completing after this UE of scheduling on a carrier wave, if this UE does not have remaining power resource, the station location marker one-tenth " can't dispatch " at this UE place in the dispatching priority formation of any one carrier wave that is not scheduled in the carrier wave of just this UE being supported.Like this, on the carrier wave that all these UE are not scheduled in the carrier wave that this UE supports, this UE will can not be scheduled again.If this UE has dump power, just to any one carrier wave that is not scheduled of this UE, upgrade the power headroom of this carrier wave.
