Detailed description of the invention
Understandable, below in conjunction with the accompanying drawings for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from
The present invention is further detailed explanation with detailed description of the invention.
Along with the development in epoch, mobile subscriber from the in early days single speech business development of demand be multimedia number
It is the mixed service demand that main, multi-service coexists according to business, and miscellaneous service exists the most different clothes
Business quality (Quality of Service, QoS) demand.In order to preferably meet the QoS demand of user,
LTE system have employed shared channel mechanism, each user, each industry in realizing community by Dynamic Resource Allocation for Multimedia
The resource-sharing of business, thus utilize time domain that system provides, frequency domain, spatial domain resource flexibly, efficiently.
Dispatching algorithm needs which running time-frequency resource is the problem solved distribute for which user, exactly to reach
Optimize user satisfaction performance and throughput of system performance, take into account the purpose of user fairness simultaneously.Scheduling
The problem that algorithm actually belongs to a nonlinear optimization.
In LTE system, scheduler is positioned at the medium access control of base station (evolved Node B, eNB)
System (MediumAccess Control, MAC) layer.Up direction, data buffer zone is positioned at user and sets
Standby (User Equipment, UE) side, eNB only need to control as the total resources of UE distribution or permit
Permitted the data total amount of transmission, according to predefined rule at different radio bearer (Radio inside UE
Bearer, RB) between Resources allocation.The major advantage of this mode is to control simply, signaling consumption
Smaller；Its major defect is that the uplink service stream that different QoS requires cannot be carried out more by scheduler
Accurately dispatching and control, the RB that priority is high is likely to be due to resource-constrained and can not get transmission for a long time.
If up using scheduling based on RB, scheduler then needs each RB for UE to distribute up money
Source or the data volume of permission transmission, UE assembles transmission block according to the court verdict of scheduler.Use this
During mode, typically requiring that UE reports the data volume in relief area corresponding to all RB, additionally base station is sent out
The resource distribution instruction sent is also required to carry out for each RB.The major advantage of this mode is scheduling
The QoS of each RB can be more accurately controlled and manage by device, and shortcoming is to control complexity, on
Descending control signaling consumption is the biggest.And down direction, data buffer zone is positioned at eNB.ENB energy
Enough know the data volume in UE each RB correspondence relief area exactly, therefore to preferably meet each
The qos requirement of RB, in LTE system, down direction uses scheduling strategy based on RB, up employing
Scheduling strategy based on UE.
In LTE system, downlink scheduler is positioned at the MAC layer of eNB, and row subframe is led in each of the lower
Cross Physical Downlink Control Channel (Physical downlink control channel, PDCCH) and send current
The scheduling instruction of subframe.In LTE, resource distribution is carried out according to the granularity of 1ms, the result bag of scheduling of resource
Include Physical Resource Block (Physical Resource Block, PRB) assignment bit map and modulation coding mode etc.
Information is transferred to UE, the UE Downlink Control Information (Downlink by PDCCH by PDCCH
Control Information, DCI) type carrys out the content of resolving resource allocation field.
In resource allocation type type 0, resource allocation information comprises a set of resources coordination contour.Position
Figure represents that eNB distributes to Resource Block group (Resource Block Groups, the RBG) letter of particular UE
Breath.
The distribution of type 0 resource uses bitmap(bitmap file) indicate RBGs to distribute to the UE that is scheduled.
Here RBGs is the PRBs of one group of continuous distribution, and the size (P) of PRB is the function of system bandwidth,
As shown in table 1.
Table 1 is the RBG size that under each downlink system bandwidth, type 0 resource allocation type is corresponding
Table 1
Whole downlink system bandwidth
Corresponding RBG quantity is
Wherein
For
Size is the RBGs number of P, if
RBGs then will exist one greatly
Little it is
Resource Block.
Bitmap is to use NRBGBits carries out bitmap to each RBG so that each RBG obtains accordingly
Addressable.
Comprehensive 3GPP 36.213 specification, the descending three kinds of resource allocation type of LTE and DCI format(DCI
Form) relation, various PDCCH DCI format support resource allocation type as shown in table 2.
Table 2 is the corresponding relation of resource allocation type and DCI format
| Resource allocation type | Type 0 | Type 1 | Type 2 |
| PDCCH DCI format | 1/2/2A/2B | 1/2/2A/2B | 1A/1B/1C/1D |

Meet, perform step 326.
Step 320, by the RBG queues to be used such as RBG the highest for priority adds to.
Step 322, deletes from the RBG of whole candidates gathers and has added to RBG queue to be used
In RBG group, and update RBG set.
Step 324, it is judged that whether available RBG set is empty.If sky, perform step 326；As
Fruit is not empty, forwards step 314 to.
Step 326, generates RBG queue the most to be used according to RBG priority descending, and
According to RBG priority descending, now can RBG sum be N.
Step 328, calculates the average MCS grade of GBR carrying according to N number of RBG to be used,
Data total amount D can be transmitted by finally can use RBG queue its all RBG of average MCS rating calculation.
Step 330, in units of RBG, the RBG in RBG queue to be used carries out data transmission,
Adjust the whole RBG collection in RBG packet queue to be used according to the application speed of GBR carrying simultaneously
The MCS grade closed, uses unified MCS grade to carry out data transmission this GBR carrying.
Specifically, above-mentioned steps 314 to step 324 can be:
The RBG(that priority is the highest is selected to be referred to as a RBG from RBG gathers), with a RBG
After updating GBR carrying demand, it is judged that whether a RBG meets the GBR after updating carries demand,
If be unsatisfactory for, a RBG being added in queue to be used, in RBG gathers, deleting the simultaneously
If a RBG(initially RBG set includes 5 RBG, the most now include 4 RBG), sentence
Disconnected now RBG set is not empty (also 4 RBG), and now, the demand of GBR carrying also updates
(the application speed of the most original GBR carrying is 512kbps, if the RBG deleted is permissible
Carrying 100kbps, the GBR after that updates are carried as 512-100=412kbps).Then at RBG collection
Again selecting the RBG(that priority is the highest in conjunction is now the 2nd RBG), after carrying out with the 2nd RBG
Continuous operation, similar reason, the demand of GBR carrying also updates (the Shen of the most original GBR carrying
Please speed be 412kbps, the GBR if the 2nd RBG deleted can carry 80kbps, after that renewal
It is carried as 412-80=332kbps), until RBG collection is combined into sky or the RBG selected in RBG gathers
Till having met the demand of GBR carrying, (demand condition meeting GBR carrying is the RBG deleted
The bit number of upper carrying is more than or equal to GBR initial application speed).When RBG collection is combined into sky, former
The RBG being unsatisfactory for GBR carrying demand in RBG set is added in RBG queue to be used,
I.e. all available RBG resource distributes to this GBR carrying.GBR carrying demand is also according to selection
The highest RBG of priority the change of carrying data volume (specially by the application speed of GBR carrying
Deduct the data volume that the highest RBG of priority can carry).
And, in step 320 etc. RBG queue to be used be i.e. from original RBG gather one by one
The RBG set that priority is deleted (is deleted a RBG set and is in fact meaned that this RBG deleted can
To be carried out resource distribution use by current GBR carrying).
The generation operation performed in step 326 needs two premises: one is that RBG collection is combined into sky, with
The GBR carrying demand of Shi Gengxin is not empty；Another is that the GBR updated is carried as sky, simultaneously from former
In beginning RBG set, priority deletes first, second one by one ... after the RBG set of priority, also have
RBG can use.
