Description

The combined scheduling method of PUSCH resource and PHICH resource and device thereof
Technical field
The present invention relates to communication technical field, relate in particular to the combined scheduling method and the device thereof of a kind of PUSCH resource and PHICH resource.
Background technology
LTE(Long Term Evolution, Long Term Evolution) the supported maximum system bandwidth of system is 20MHz, in order to support broadband system better, the LTE system adopts SC-FDMA(Single Carrier – Frequency Division Multiple Access, single-carrier frequency division multiple access), at frequency domain whole wideband frequency selective channel is divided into a plurality of smooth subchannels, mutually orthogonal between each subchannel.Under the situation of multi-user service coexistence, can distribute running time-frequency resource to carry out transfer of data neatly.Assignable minimal physical resource units is PRB(Physical Resource Block, Physical Resource Block), continuous width is that the physical resource of 180kHz becomes a PRB on time slot frequency domain.In order to support PUSCH(Physical Uplink Shared Channel, Physical Uplink Shared Channel) single-carrier property of transmission, the PUSCH resource adopts the mode of continuous dispensing, promptly requires to distribute to a PRB resource that the user is continuous.
In order to improve resource utilization and throughput of system, satisfy the QoS(Quality of Service of miscellaneous service, QoS) demand, LTE system are used shared channel mechanism, and the mode by Dynamic Resource Allocation for Multimedia realizes each user in the system, each professional resource-sharing.Be used for UE(User Equipment, user terminal) the channel of transmitting uplink data be called PUSCH.
The LTE system uses PHICH(Physical Hybrid ARQ Indicator Channel, hybrid automatic repeat request indication channel) transmission mixes automatic repeat requests at the HARQ(Hybrid Automatic Repeat Request of PUSCH packet) feedback (ACK/NACK) information.UE is according to this feedback information decision whether carrying out re-transmission of PUSCH packet.There are the certain time sequence relation in descending ACK/NACK feedback and corresponding PUSCH transmission, and therefore for the transmission of the PUSCH on the same subframe, its corresponding ACK/NACK feedback is also carried out at same descending sub frame.The PHICH resource is mapped to the control area of descending sub frame.According to system configuration system's PHICH resource is divided into several PHICH groups, each PHICH group takies different running time-frequency resources; The ACK/NACK information that each PHICH group can be carried a plurality of UE, the ACK/NACK of different UEs carries out code division multiplexing in the same PHICH group, and the ACK/NACK number of bits upper limit that can carry out code division multiplexing is determined.Therefore, the PHICH resource of UE is by a pair of numbering Sign, wherein
Figure GDA00002974794000022
Be PHICH group sequence number, Be the orthogonal sequence numbering in a group, the concrete computing formula of these two numberings is:
n PHICH group = ( I PRB _ RA lowest _ index + n DMRS ) mod N PHICH group + I PHICH N PHICH group
Figure GDA00002974794000025
Wherein, n DMRSBe and the corresponding PDCCH(Physical Downlink Control Channel of PUSCH transmission, Physical Downlink Control Channel) the DMRS(Demodulation reference signal of indication in, demodulation reference mark) cyclic shift value, if the PUSCH transmission of the PUSCH of semi-continuous scheduling correspondence or accidental access response scheduling, n DMRSBe made as 0; It is the spreading factor size of PHICH modulation; It is the minimum PRB sequence number that corresponding PUSCH transmits first time slot allocation;
Figure GDA00002974794000028
It is PHICH group number;
Figure GDA00002974794000029
Can see that by above formula the PHICH resource location of UE is that minimum PRB sequence number and user class DMRS cyclic shift determined jointly in the resource that is taken by PUSCH transmission.
When carrying out uplink scheduling, at first all UE use identical n in the default cell at present DMRS, after finishing the PUSCH resource allocation, according to PUSCH resource allocation result and n DMRSInitial value calculates the PHICH resource location, if find the PHICH resource contention then by adjusting n DMRSAttempt changing the PHICH resource location, if can be assigned to the PHICH resource, then current UE is dispatched successfully; Otherwise this does not dispatch current UE.
The inventor finds that there is following defective at least in prior art in realizing process of the present invention:
Present dispatching method is to distribute the PUSCH resource earlier, distributes the PHICH resource by adjusting user class DMRS cyclic shift after finishing the PUSCH resource allocation.Adopt this method, under the situation of PHICH resource contention, adjust user class DMRS cyclic shift on the one hand and have certain complexity; On the other hand, the DMRS cyclic shift of each UE is determined jointly by cell-level DMRS cyclic shift and user class DMRS cyclic shift.Under identical networking, use identical PUSCH resource to carry out the user of transfer of data for neighbor cell, need to distribute different DMRS cyclic shifts to guarantee that the mutual orthogonality of its DMRS is to reduce the minizone co-channel interference.Can guarantee that by allocating cell level DMRS cyclic shift the co-channel interference of minizone minimizes.For following this principle, need take into account different districts when giving each UE distributing user level DMRS cyclic shift uses identical PUSCH resource to carry out the user's of transfer of data the distribution condition of user class DMRS cyclic shift, be that the user that neighbor cell uses identical PUSCH resource to carry out transfer of data need distribute identical user DMRS cyclic shift, therefore above limiting factor has limited the degree of freedom that user class DMRS adjusts to a great extent when the PHICH resource contention occurring, thereby influence is to the scheduling of UE, increase the transmission of uplink data time delay, be unfavorable for guaranteeing QoS of survice.

Embodiment
The embodiment of the invention proposes the technical scheme of a kind of PHICH resource and PUSCH resource combined dispatching.In this technical scheme, at first determine to participate in the UE priority query of frequency domain dispatching based on known time domain dispatching method, UE for each frequency domain dispatching, at first determine its user class DMRS cyclic shift, and the current PHICH resource of coupling system can determine with situation can not be as the initial PRB sequence number of the PUSCH transmission of this UE, according to this limiting factor current UE is carried out the PUSCH resource allocation then, after the PUSCH resource allocation of finishing current UE, its corresponding PHICH resource has also just been determined.This method also for this UE is assigned to the PHICH resource, and guarantees that the PHICH resource between each UE can not conflict when distributing the PUSCH resource for UE, guaranteed the transmission performance of PUSCH and PHICH simultaneously.
Below in conjunction with accompanying drawing the embodiment of the invention is described in detail.
Referring to Fig. 1, the PHICH resource that provides for the embodiment of the invention and the schematic flow sheet of PUSCH resource combined dispatching.This flow process is applicable to the single antenna transmissions of PUSCH, is called for short MU-MIMO in the sub-district after promptly not considering to adopt virtual MU-MIMO() situation, do not consider that promptly the user of same sub-district uses identical PUSCH resource to carry out the situation of transfer of data.As shown in the figure, this process can comprise:
Step 101 is determined the user class DMRS cyclic shift value of UE in the system.Under the single antenna transmissions scene, for the identical user class DMRS cyclic shift of all UE configurations, such as all being configured to 0.
Step 102, the domain scheduling when UE in the current system is carried out, definite UE priority query that participates in frequency domain dispatching.
Step 103, the priority of the UE that the UE(that takes out limit priority from the UE priority query that participates in frequency domain dispatching takes out from head of the queue usually is the highest), can use situation according to current system PHICH resource, user class DMRS cyclic shift in conjunction with current UE, determine the initial PRB resource location that can not transmit as the PUSCH of current UE, promptly, determine such PRB resource location, the PRB resource of described PRB resource location can not be as the initial PRB resource in the continuous P RB resource that can distribute to current UE.
Step 104 can be used situation according to the current PUSCH of system, and step 103 determines can not be that current UE is distributed the PUSCH resource as the initial PRB resource location of the PUSCH of this UE transmission.
Step 105, according to the PUSCH resource allocation result of current UE, and the definite user class DMRS cyclic shift of step 101, determine corresponding PHICH resource, with this PHICH resource dispensing current UE.
Concrete, after the initial PRB position of distributing to UE and user class DMRS cyclic shift are determined, just can be defined as this UE distribution PHICH resource according to the PHICH resource computing formula that formula [1] provides.
Step 106, update system can be used PUCCH resource and available PHICH resource, deletes current UE from frequency domain dispatching UE priority query.
Step 107 is if UE priority query then changes step 103 over to not for empty and current system also have available PUSCH resource and PHICH resource; Otherwise this finishing scheduling withdraws from flow process.
In the step 103 in the flow process shown in Figure 1, can use situation,, determine the process of the initial PRB resource location that can not transmit, can comprise as shown in Figure 2 as the PUSCH of this UE in conjunction with the user class DMRS cyclic shift of current UE according to current system PHICH resource:
Step 201 according to the system resource configuration, is determined PRB resource and PHICH resource mapping relation.
Concrete, can see from the computing formula [1] of PHICH resource, when be when all UE distribute identical user class DMRS cyclic shift in the system, the minimum PRB resource sequence number of PUSCH transmission correspondence

And there is following rule in the mapping relations between the PHICH resource:
(1) adjacent Be mapped to adjacent PHICH group;
(2) be spaced apart

Be mapped to identical PHICH group, and distinguish by orthogonal sequence.
In the LTE system, suppose that the PUSCH resource comprises 50 PRB, system PHICH is configured to

According to above rule, under current supposing the system resource distribution, when user class DMRS cyclic shift value is 0,

To PHICH resource mapping relation as shown in Figure 3, each lattice is represented a PHICH resource among the figure, the PHICH resource of each row is one group, the orthogonal sequence numbering that the PHICH resource of different rows is corresponding different, the numeral in the grid is mapped to the PUSCH PRB resource number of this PHICH resource correspondence.Wherein, adjacent
Figure GDA00002974794000077
Be mapped to adjacent PHICH group, PRB0 as shown in Figure 3 is mapped to PHICH group 0, and PRB1 is mapped to PHICH group 1, by that analogy; Be spaced apart
Figure GDA00002974794000078
Figure GDA00002974794000079
Be mapped to identical PHICH group, PRB0 as shown in Figure 3, PRB3, PRB6 ... be mapped to same group (PHICH group 0).
Step 202 can be used situation according to current system PHICH resource, determines the initial PRB sequence number that can not transmit as the PUSCH of current UE.
Concrete, can concern according to PRB resource and the PHICH resource mapping that step 201 is determined, with the pairing PRB sequence number of the PHICH resource of distributing to other UE, be defined as distributing to the PRB resource location of current UE as initial PRB.It still is example with Fig. 3, suppose that the PHICH resource that white lattice is represented among Fig. 3 is current available PHICH resource, the PHICH resource that oblique line filling lattice is represented is for having distributed to the PHICH resource of other UE, then for current UE, PRB0, PRB7, PRB15, PRB24, PRB31, PRB39, PRB48, these PRB can not distribute to the initial PRB of current UE as the PUSCH transmission.
In the step 104 in the flow process shown in Figure 1, can use situation according to the current PUSCH of system, and the initial PRB resource location that can not transmit as the PUSCH of current UE, the process for current UE distribution PUSCH resource can comprise as shown in Figure 4:
Step 401 according to current available PUSCH resource situation, is determined available continuous P RB resource segmentation.
Concrete, for the current available PRB resource of system, the principle continuous according to the PRB resource merges, and obtains available continuous P RB segmentation.For ease of describing, in the present embodiment, the quantity of the available continuous P RB segmentation that obtains is designated as K, the PRB number that each available continuous P RB segmentation comprises is designated as N respectively PRB_usable_segk(0≤k＜K).
Step 402 determines that according to current UE data to be transmitted amount needs are the PRB quantity that current UE is distributed.
Determine that according to UE data to be transmitted amount needs are that the method for the current UE PRB quantity of distributing is a lot, estimation that can be rough, as estimating in the average channel quality of whole system bandwidth according to current UE, this moment, the PRB number of required distribution was above-mentioned estimated value for each available continuous P RB segmentation.The embodiment of the invention preferably adopts the average CQI on the PRB that comprises according to each available continuous P RB segmentation respectively the PRB number demand of each available continuous P RB segmentation to be estimated, it mainly is the otherness of considering UE CQI on each PRB, obviously, this method is more accurate than the former.Concrete, for each available continuous P RB segmentation, based on the CQI(Channel Quality Indicator of current UE on these PRB, CQI), according to AMC(Adaptive Modulation Coding, Adaptive Modulation and Coding) algorithm is determined corresponding MCS(Modulation and Coding Scheme, Modulation and Coding Scheme), and calculate this MCS of use according to current UE data to be transmitted amount and carry out the PRB number N that the transfer of data needs distribute PRB_need_segk(0≤k＜K).
Step 403, the PRB quantity of distributing for current UE is carried out PRB preassignment for current UE respectively in each available continuous P RB segmentation as required.
In this step,, can select the interior optimum resource of this continuous P RB segmentation, promptly in each available continuous P RB segmentation, carry out PRB preassignment by carrying out the sliding window operation for each available continuous P RB segmentation.
Concrete, for available continuous P RB segmentation k(0≤k＜K), the sliding window window of at first definite this available continuous P RB segmentation is long:
L window_segk＝min{N PRB_need_segk,N PRB_usable_segk}……[2]
Suppose that the initial PRB resource collection that can not distribute to current UE that can determine with situation according to current system PHICH resource is Ω, then can distinguish in the following way and handle at different situations:
Situation one: if L Window_segk=N PRB_usable_segk, show that then the PRB quantity that current available continuous P RB segmentation is comprised is less than or equal to the needed PRB quantity of current UE.For L Window_segk=N PRB_usable_segkAvailable continuous P RB segmentation, do not need to carry out sliding window.If the initial PRB of this available continuous P RB segmentation does not belong to set omega, then all the PRB resources in this available continuous P RB segmentation are the pre-allocation resource of corresponding available continuous P RB segmentation; Otherwise, will remove in this available continuous P RB segmentation the residue continuous P RB resource behind the initial PRB as the pre-segmentation resource of this available PRB contiguous segmentation.
Situation two: if L Window_segk＜N PRB_usable_segk, show that then PRB quantity that current available continuous P RB segmentation comprised is greater than the needed PRB quantity of current UE.For
Figure GDA00002974794000091
Available continuous P RB segmentation, need to carry out sliding window.Suppose preceding N in this available continuous P RB segmentation PRB_usable_segk-L Window_segkAmong+1 PRB N ' is arranged PRB_segkIndividual PRB belongs to set omega (promptly can not as the initial PRB that distributes), and then the number of times of execution sliding window is N in this available continuous P RB segmentation PRB_usable_segk-L Window_segk+ 1-N ' PRB_segkThe L of optimum (the highest as average CQI) in this available PRB segmentation is picked out in operation based on sliding window Window_segkIndividual continuous P RB resource.
Further, if in above-mentioned situation one or the situation two, for each available continuous P RB segmentation, according to PRB pre-allocation of resources result, if the PRB number that the PRB number of therefrom selecting comprises less than this available continuous P RB segmentation, there is some difference owing to the CQI of UE on each PRB, need this moment recomputate corresponding MCS according to the AMC algorithm according to the CQI on these PRB that select, and further determine on these PRB, to use this MCS mode to carry out transfer of data can the data carried by data amount.
Step 404 is by comparing the PRB pre-allocation of resources result of each available continuous P RB segmentation, the final decision of making resource allocation.
The basic thought of resource allocation decisions is the QoS(Quality of Service that preferentially guarantees UE, service quality) requirement is the demand that guarantees the UE transfer of data specific to each resource allocation, on this basis, improve the efficient of transfer of data, to improve system spectral efficiency as far as possible.Based on above principle, the embodiment of the invention is according to the Data-carrying ability and the efficiency of transmission of each preassignment PRB resource, determine the priority of each preassignment PRB resource, select the highest preassignment PRB resource of its medium priority, give current UE as the PUSCH resource allocation, concrete, preferably adopt following resource allocation decisions method:
At first, according to preallocated continuous P RB in current UE data to be transmitted amount and each the continuous P RB segmentation can data quantity transmitted comparative result, all PRB preassignment results are divided into two S set 1 and S2: the PRB preassignment result who data transmission capabilities is not less than the transfer of data demand is divided into S set 1; Data transmission capabilities is divided into S set 2 less than the PRB preassignment result of transfer of data demand.Obviously, the PRB preassignment result who satisfies the transfer of data demand has higher priority, and promptly the priority of two set is: S1〉S2;
Then, for each the PRB preassignment result in the S set 1, because its Data-carrying ability satisfies the transfer of data demand, in order to guarantee efficiency of transmission, can come to determine respectively the priority orders of each preassignment PRB with each self-corresponding MCS of each preallocated PRB in conjunction with the priority of S set 1.MCS is high more, and efficiency of transmission is high more, and corresponding usually PRB number is few more, and its priority is also high more.
For each the PRB preassignment result in the S set 2, because its Data-carrying ability does not satisfy the transfer of data demand, in order to guarantee real time of data transmission as far as possible, can be in conjunction with the priority of S set 2, can carry data volume as the Determination of priority standard with preallocated PRB, it is big more to carry data volume, and corresponding priorities is high more.
At last, select priority the highest among the PRB pre-allocation of resources result of each the available continuous P RB segmentation from S set 1 and S set 2, as the final result of PUSCH resource allocation.
More than by comparing the PRB pre-allocation of resources result of each available continuous P RB segmentation, the implementation of making the final decision of resource allocation only is a kind of optimal way, if the resource allocation policy difference requires to be higher than qos requirement as efficiency of transmission, then the corresponding meeting that is provided with of priority height changes to some extent.In addition, according to data transmission capabilities, preassignment PRB is at first assigned to different sets, just realize for the ease of technology, those skilled in the art should be able to carry out resource decision by similar fashion based on above-mentioned basic thought, as not dividing different sets, but predesignate the rule that priority is set according to data transmission capabilities and efficiency of transmission, and the weights of data transmission capabilities are set to be higher than the weights of efficiency of transmission.
In the PHICH resource that the above embodiment of the invention proposes and the combined scheduling method of PUSCH resource, UE for each frequency domain dispatching, at first determine its user class DMRS cyclic shift, and the current PHICH resource of coupling system can determine with situation can not be as the initial PRB sequence number of the PUSCH transmission of this UE, according to this limiting factor current UE is carried out the PUSCH resource allocation then, after the PUSCH resource allocation of finishing current UE, its corresponding PHICH resource has also just been determined.This method also for this UE is assigned to the PHICH resource, and guarantees that the PHICH resource between each UE can not conflict when distributing the PUSCH resource for UE, guaranteed the transmission performance of PUSCH and PHICH simultaneously.
Based on identical technical conceive, the embodiment of the invention also provides a kind of resource scheduling device that can be applicable to above-mentioned flow process, and this device can be a base station equipment.
