Description
Technical field
The present invention relates to wireless communication field more particularly to a kind of resource regulating methods and device.
Background technology
In long term evolution (Long Term Evolution, LTE) system, media intervene control layer (media access
Control layer, MAC) it is mainly responsible for and distributes time domain and frequency domain resource for different scheduling of user terminals, wherein dispatching party
Net used in the size of cell throughout where the quality of method directly influences each user terminal and each user terminal
Network service speed.
In general, under the premise of ensureing that each user terminal uses fairness to resource, for scheduling of user terminals
When distributing time domain and frequency domain resource, the utilization rate of resource can be promoted as far as possible, to meet the service quality of different business.
For example, for the user terminal in a cell, each user terminal shares limited bandwidth resources, often
The network service that one user terminal carries out is different, moreover, the channel quality of each user terminal is different, so, it is different
User terminal between according to service quality rating mark can distinguish different dispatching priorities.
Can be channel when distributing time domain and frequency domain resource for scheduling of user terminals if paying the utmost attention to the handling capacity of cell
The more resource of the high user terminal distribution of quality, the corresponding resource for reducing bad channel quality or cell edge user terminal, in this way,
It can influence the fairness that each user terminal uses resource；If preferentially examining fairness, to the user terminal of different channels quality
The identical resource of dispatching distribution in this way, not only resulting in the wasting of resources, but also can influence the network service of other users terminal
Rate, and influence the handling capacity of entire cell.
For the distribution of time domain and frequency domain resource, there are following three kinds of scheduling schemes in the prior art.
Scheme one is max carrier to interference (MAX Carrier/Interference, MAX C/I) algorithm, that is, for difference
When user terminal is scheduled, pays the utmost attention to the user terminal with max carrier to interference, be equivalent to, pay the utmost attention to channel quality compared with
Good user terminal can reselect channel quality and preferably use if selected user terminal present channel quality is deteriorated
Family terminal.
Using scheme one, although having paid the utmost attention to the user terminal that channel quality is good, maximum it can ensure handling up for cell
Amount, but being unfair property, reduce the user terminal of bad channel quality and the sensory experience of cell edge user terminal.
Scheme two is repeating query (Round Robin, RR) algorithm, that is, is cyclically each scheduling of user terminals time domain and frequency
Domain resource, no matter the quality of channel quality, can obtain identical for the different user terminals in different community position
Dispatcher meeting.
Using scheme two, although the fairness of each user terminal can ensure that greatest extent, due to inabundant
In view of the different channels quality of different user terminals, the user terminal of cochannel quality obtains the identical dispatching distribution time,
Affect the handling capacity of entire cell.
Scheme three is Proportional Fair (Proportional Fair, PF) algorithm, that is, the clothes asked with user's current time
The ratio between the rate and the accumulative Mean Speed in a period of time of being engaged in (for convenience of description, being indicated below with C) weigh dispatching priority, example
Such as, if certain user terminal present channel quality is preferable so that C values increase, then corresponding dispatching priority also can accordingly increase, and one
After the section time, since the dispatching priority of the user terminal is constantly in high priority state, correspondingly, accumulative Mean Speed
And then increase, decline so as to cause C values, in turn, the dispatching priority of the user terminal also can and then decline, and for channel matter
It measures for poor user terminal, in a period of time, if dispatching priority is relatively low always, adds up Mean Speed and also and then drop
It is low, cause C values to rise, to which the dispatching priority of the user terminal also can and then rise.
Using scheme three, although the fairness and channel quality of different user terminals can be taken into account, do not consider not
With the different business characteristic of user terminal and service quality etc. factor, specific certain one-sidedness.
In view of this, needing to design a kind of new resource scheduling scheme to overcome drawbacks described above.

The resource allocation factor of determination according to each user terminal data volume to be transmitted, from the corresponding use of each user terminal
It is corresponding user terminal distribution resource block in the grade resource block queue of family.
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, is not whole embodiment.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The solution of the present invention will be described in detail by specific embodiment below, certainly, the present invention is not limited to
Lower embodiment.
Specifically, user terminal before initiation business, can be submitted based on type of service to the base station side of administration place cell
Resource block demand is the corresponding resource block of user terminal division after base station side receives the resource block demand of user terminal, but due to
Base station side simultaneously scheduling user terminal number it is limited, therefore, need to the different service types of different user terminals divide money
Source block determines a priority factors, which kind of the type of service scheduling resource block for being preferably which user terminal with determination.
In the embodiment of the present invention, a kind of priority algorithm is provided, it, can not only be simultaneously relative to existing priority algorithm
The fairness and service quality of user terminal are taken into account, and traversal number is few, operation is simpler, specifically, whole for different user
The corresponding resource block of different service types at end determines that the method for priority factors is as follows：
First, the corresponding quality of service factor of the resource block is determined, wherein quality of service factor indicates the clothes of the resource block
Accounting of the quality of being engaged in total service quality can be calculated by the following formula i-th of resource preferably, in the embodiment of the present invention
The quality of service factor Y of blocki：
Wherein, qiIndicate the corresponding service quality weight factor of i-th of resource block, size can basis
Actual conditions (e.g., business urgency level) make corresponding adjustment,Indicate the corresponding service quality weight of each resource block
The sum of factor, I indicate resource block sum.
Certainly, in the embodiment of the present invention, service quality (Quality of Service, QoS) can also simply be used
Class parameter indicates rate requirement and delay requirement to different business as quality of service factor.
Secondly, it is based on preset correspondence between each resource block and each user terminal, determines that the resource block corresponds to
User terminal, and determine the current corresponding maximum scheduling rates of user terminal and user terminal within a preset period of time
Average transmission rate, and corresponded to based on the corresponding maximum scheduling rates of user terminal and average transmission rate and the resource block
Quality of service factor, determine the candidate priorities factor of the resource block.
Preferably, in the embodiment of the present invention, the candidate priorities factor of i-th of resource block can be calculated by the following formula
Xi：
Wherein, YiFor the above-mentioned quality services factor provided, Lj(T)It is corresponded to for i-th of resource block
User terminal j maximum scheduling rates, Vj(t)For the corresponding user terminal j of i-th of resource block putting down within a preset period of time
Equal transmission rate.
About maximum scheduling rates, preferably, in the embodiment of the present invention, i-th of resource can be calculated by the following formula
The maximum scheduling rates L of the corresponding user terminal j of blockj(T)：
Wherein, Hi(T)The maximum data that can be transmitted in preset T dispatching cycle for user terminal j
Amount, and the maximum amount of data H of user terminal ji(T), can be by tabling look-up to obtain, specifically, being based on channel quality information and noise
The I more current than determining userMCSThe value of modulation and coding strategy (Modulation and Coding Scheme, MCS), then base
In the value I of MCSMCSDetermine ItbsTransmitting block index is numbered, and I is finally based ontbsDetermine Nprb, that is, required number of resources, and
NprbIt is equivalent to Hi(T), and then determine Hi(T)。
Finally, be based on the corresponding application scenarios of the resource block in preset experience factor, to the candidate priorities factor into
The corresponding adjustment of row, obtains priority factors, in this way, by using experience factor, corresponding adjustment is carried out to the candidate priorities factor,
Can more delicately correct a period of time in some user terminal obtain always high priority sequence occupy resource block, and other
The case where user terminal persistently obtains low priority sequence and can not obtain resource block.
As shown in fig.1, in the embodiment of the present invention, resource regulating method flow is as follows：
Step 100：Base station side determines each resource block to be scheduled.
Specifically, before base station side is the different business scheduling resource block of different user terminals, first determination waits for base station side
Each resource block of scheduling.
Step 101：Base station side determines the priority factors of each resource block based on preset priority algorithm, and according to each
The corresponding priority factors of a resource block determine priority orders, form resource block queue.
Specifically, base station side determines the priority factors of each resource block based on preset priority algorithm, and based on each
The corresponding priority factors of a resource block, determine the priority orders between each resource block, and above-mentioned each resource block is pressed
Resource block queue is formed according to priority orders.
For example, it is assumed that base station side determines that there are 3 resource blocks to be scheduled, and assume the meter by above-mentioned priority algorithm
It calculates, determines that the priority factors of resource block 1 are 4, the priority factors of resource block 2 are 3, and the priority factors of resource block 3 are 5,
So, the priority of resource block 3 is highest, and the priority of resource block 1 is secondary high, and the priority of resource block 2 is time time height, and according to
It is secondary that resource block 3, resource block 1 and resource block 2 are put into resource block queue, shown in Fig. 2.
In the embodiment of the present invention, why resource block to be scheduled is put into queue by base station side according to the priority of definition
In, be because base station side simultaneously for different user terminals carry out scheduling of resource when, can be limited to itself configure or other, can adjust
The number of the user terminal of degree is limited, is first each resource block to be scheduled in advance according to preset priority algorithm therefore
The priority for distributing equity is followed successively by corresponding user terminal and carries out scheduling of resource according to the height of priority.
Step 102：Base station side chooses a resource block successively from resource block queue according to priority orders.
Specifically, after base station side determines resource block queue, one is chosen successively according to priority orders from resource block queue
A resource block.
For example, it is assumed that there are 5 resource blocks in current resource block queue, as shown in fig.3, wherein, resource block 3 it is preferential
Grade is higher than resource block 5 higher than resource block 2 higher than resource block 1 higher than resource block 4, and a resource is once chosen according to priority orders
Block.
Step 103：Base station side is based on preset correspondence between each resource block and each user terminal, determines current
The corresponding user terminal of resource block of acquisition.
It is the industry by user terminal according to itself specifically, due to each resource block to be scheduled that base station side determines
Business demand is initiated to base station side, and therefore, each resource block is known specifically to correspond to for which user terminal, specifically, one
Resource block corresponds to a user terminal, and a user terminal corresponds at least one resource block.
For example, still being illustrated with above-mentioned, it is assumed that resource block 3 and resource block 4 correspond to user terminal 1 (UE1), resource block 1
Corresponding user terminal 2 (UE2), resource block 2 and resource block 5 correspond to user terminal 3 (UE1), then, if the resource block of this extraction
For resource block 2, it is determined that resource block 2 corresponds to user terminal 3.
Step 104：The resource block of acquisition is added in the corresponding user class resource block queue of the user terminal by base station side,
And the resource block is deleted from the corresponding position of resource block queue.
Specifically, after base station side determines the corresponding user terminal of resource block extracted, which is put into corresponding use
In the corresponding user class resource block queue of family terminal, and the corresponding position of the resource block empties in resource block queue, wherein if
Existing resource block in the user class resource queue of the corresponding user terminal of resource block, the then newest resource block meeting being put into of base station side
Cross-layer is carried out with the already present resource block in user class resource block queue Central Plains to merge.
For example, still illustrated with above-mentioned, if the resource block that base station side is currently extracted is resource block 1, and, it has been determined that resource
Block 1 corresponds to user terminal 2, then, resource block 1 can be gone out team by base station side from resource block queue place, corresponding into user terminal 2
In user class resource block queue, correspondingly, resource block 2 can be emptied in the position of resource block queue.
Step 105：Base station side judges whether the corresponding user terminal total number of each resource block chosen reaches default
Otherwise the upper limit, executes step 102 if so, thening follow the steps 106.
Specifically, since the user terminal number that base station side is dispatched simultaneously is limited, a upper limit can be preset,
So that base station side often chooses a resource block and can execute primary judgement, the corresponding user terminal of each resource block chosen is judged
Whether total number reaches preset upper limit, if so, thening follow the steps 106, otherwise, executes step 102.
For example, it is assumed that preset upper limit is 2, still illustrated with above-mentioned example, base station side extracts resource block 3 for the first time, really
Determine resource block 3 and correspond to user terminal 1, and resource block 3 is put into 1 corresponding user class resource block queue of user terminal, due to
The corresponding user terminal total number of resource block chosen is therefore 1, not up to preset upper limit 2 execute step 102, that is, base
Side of standing continues to extract resource block 1, determines that resource block 1 corresponds to user terminal 2, and resource block 1 is put into 2 corresponding use of user terminal
In the grade resource block queue of family, since the corresponding user terminal total number of the resource block chosen is 2, preset upper limit 2 is had reached, because
This, executes step 106.
In another example, it is assumed that preset upper limit 3 is still illustrated with above-mentioned example, and process is 2 classes with a upper preset upper limit
Seemingly, it repeats no more, due to 5 resource blocks in resource block queue, has only corresponded to three user terminals, therefore, resource block queue
In resource block can all be selected, finally determine user terminal 1, user terminal 2 and user terminal 3 user class resource queue
See Fig. 3.
Step 106：Base station side is based respectively on each user terminal data volume to be transmitted chosen, and determines each
The corresponding resource allocation factor of user terminal.
Specifically, base station side can be determined above-mentioned every first based on each user terminal data volume to be transmitted chosen
Resource block (also referred to as transmission block) needed for one user terminal data volume to be transmitted, it is then, whole based on each above-mentioned user
Resource block needed for end, and resource block needed for each user terminal for having chosen total amount, determine each user end
Hold the corresponding resource allocation factor.
Preferably, in the embodiment of the present invention, the resource allocation factor W of user terminal k is calculated using following formulak：
Wherein, rkFor the transport block size needed for user terminal k,For each use chosen
The total size of transmission block needed for the terminal of family, K are the number for the user terminal chosen.
Step 107：The resource allocation factor of the base station side based on each user terminal chosen is used from each respectively
It is corresponding user terminal distribution resource block in the corresponding user class resource block queue of family terminal.
Specifically, after the resource allocation factor for each user terminal that base station side determination has been chosen, it can be according to each use
The resource allocation factor of family terminal determines the money that the resource block needed for user terminal includes in corresponding user class resource block queue
Then the ratio occupied in source block in corresponding user class resource block queue, is distributed according to priority orders for user terminal
The resource block being consistent with the ratio.
Preferably, in the embodiment of the present invention, the specific resource block n of user terminal k distribution is calculated using following formulak：
nk=N*Wk, wherein the resource block total amount of schedulable, W in the user class resource block queue that N is user terminal kkFor
The resource allocation factor of above-mentioned known user terminal k.
Step 108：Base station side judges whether there is also untreated resource blocks in resource block queue, if so, executing step
Rapid 102, otherwise, scheduling of resource terminates.
Specifically, since the user terminal number of base station side scheduling is limited, so according to priority orders, it is in batches
User terminal carries out scheduling of resource, moreover, after each batch scheduling of resource, can update each user terminal default
Average transmission rate in period.
Preferably, in the embodiment of the present invention, can be used following formula to user terminal k preset time period average transmission
Rate：
Wherein, Vi(t)Indicate the average transmission rate at current time, Vi(t-Δt)It indicates
The average transmission rate of last moment, Pi(t)Indicate user's current request rates, T indicates the time window of definition, by above-mentioned formula
It is found that if the setting of T values is larger, the variation of the average transmission rate of user terminal can tend towards stability so that the priority of calculating
The susceptibility of factor pair average transmission rate is relatively low, conversely, susceptibility of the priority factors then calculated to average transmission rate
It is higher.
Further, if after first batch scheduling of resource, there is also not scheduled resource block in resource block queue,
Then continue to obtain not scheduled resource block successively according to priority, until there is no not scheduled resources in resource block queue
Until block.
