Description
Technical field
The present invention relates to mobile communication technologies, more particularly to a kind of resource allocation methods and device.
Background technique
Existing Uu mouthfuls of resource allocation methods are: in several business of each user equipment (UE), choosing highest priority
Business priority of the priority as UE, UE is ranked up according to the sequence of UE priority from high to low, is followed successively by every
A UE carries out resource allocation.In resource allocation process, if UE is all distributed or PDCCH/PUSCH/PDSCH resource exhaustion,
Then terminate the resource allocation of this dispatching cycle.In resource allocation process, when light load, PDCCH channel resource is unrestricted,
It can be matched with traffic channel resource, resource can be distributed for more UE.
V2V business refers to the business transmitted between vehicle and vehicle, and there are two types of transmission modes for the business: one is be based on PC5
The V2V business of mouth, i.e., auxiliary link (SL) business；Another kind is the V2V business based on Uu mouthfuls.
After system introduces SL business, when carrying out the transmission of SL business, eNB is passed through the control information of SL business by Uu mouthfuls
Downlink Control Information 5A (DCI 5A) is sent to UE, notice UE resource allocation as a result, UE receives DCI 5A after, utilize PC5 mouthfuls
SL transmission is carried out to the other UE in periphery.It can be seen that eNB is after UE distributes resource, to need DCI through LTE PDCCH channel
5A is sent to UE.Therefore, after introducing SL business, the CCE resource of LTE PDCCH channel will be by carrying the control of two class of UL/DL originally
Information becomes carrying UL/DL/SL three classes control information.
After introducing SL business, DCI 5A occupies the CCE resource of part PDCCH channel, so that with SL business is introduced
It compares before, the available PDCCH channel resource of upstream or downstream (UL/DL) can be reduced, and the UL/DL DCI that PDCCH can be carried is a
Number is also corresponding to be reduced, and is reduced so as to cause the schedulable UE number of UL/DL.And Traffic Channel to be scheduled increases PSSCH channel.
Therefore, after system introduces SL business, since PDCCH resource is limited, lead to PDCCH channel resource and PUSCH/
PDSCH/PSSCH three classes traffic channel resource no longer matches, in this way, if still will lead to according to existing resource allocation algorithm
Occur: although leading to not the case where dispatching without available PDCCH resource there are also available traffic channel resource, from
And the efficiency of transmission that will lead to UE reduces, while will cause the waste of PUSCH/PDSCH/PSSCH channel resource.
Summary of the invention
In view of this, can effectively be solved the main purpose of the present invention is to provide a kind of resource allocation methods and device

If currently without remaining physical downlink control channel PDCCH resource, and at least one has distributed the use of resource
Family meets preset resource reallocation condition, then is to meet using remaining traffic channel resource by resource redistribution process
The user of the resource reallocation condition distributes traffic channel resource；The resource reallocation condition is to have the industry of unallocated resource
It is engaged in and corresponding traffic channel resource currently has residue.
A kind of resource allocation device, comprising:
First allocation unit, for user to be dispatched for each of current dispatching cycle, according to the business of the user
Highest priority, determine User Priority；The user to be dispatched is traversed according to the descending of User Priority, to be described wait adjust
The highest priority traffic for spending user distributes corresponding traffic channel resource；The business includes Uu port service and PC5 port service；
Reallocation unit is used for after the first allocation unit completes resource allocation, if currently without under remaining physics
Row control channel PDCCH resource, and at least one user for having distributed resource meets preset resource reallocation condition, then passes through
Resource redistribution process is the user's distribution business letter for meeting the resource reallocation condition using remaining traffic channel resource
Road resource；The resource reallocation condition is to have the business of unallocated resource and corresponding traffic channel resource currently has residue.
In conclusion resource allocation methods proposed by the present invention and device, after PDCCH resource exhausts, still through money
Source redistribution process distributes remaining traffic channel resource to the user for having obtained PDCCH resource, in this way, business may be implemented

The problem of taking.
Detailed description of the invention
Fig. 1 is the method flow schematic diagram of the embodiment of the present invention；
Fig. 2 is the apparatus structure schematic diagram of the embodiment of the present invention.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, right below in conjunction with the accompanying drawings and the specific embodiments
The present invention is described in further detail.
Core of the invention thought is: after first time resource allocation, within the scope of the UE for being assigned to PDCCH resource,
Continue to be that these UE distribute traffic channel resource based on available traffic channel resource, in this way, Traffic Channel can be improved sufficiently
The utilization rate of resource and the efficiency of transmission of UE, transmission efficiency is low and traffic channel resource wave by UE after effectively solving introducing SL business
The problem of taking.
Fig. 1 is the method flow schematic diagram of the embodiment of the present invention, as shown in Figure 1, the embodiment specifically includes that
Step 101, user to be dispatched for each of current dispatching cycle, the highest according to the business of the user are preferential
Grade, determines User Priority；The user to be dispatched is traversed according to the descending of User Priority, most for the user to be dispatched
High-priority service distributes corresponding traffic channel resource；The business includes Uu port service and PC5 port service.
This step is corresponding for the distribution of its highest priority traffic for traversing the user to be dispatched in current dispatching cycle
Traffic channel resource.
Preferably, following methods can be used, phase is distributed for the highest priority traffic of the user to be dispatched traversed
The traffic channel resource answered:
If the user to be dispatched currently traversed has available PDCCH resource, and has and user's highest priority industry
It is engaged in corresponding traffic channel resource, is then that the user distributes corresponding PDCCH resource and traffic channel resource；
If resource collision occurs for the available PDCCH resource of the user to be dispatched currently traversed, abandon to the user's
Resource allocation；
If terminating the traversal currently without available traffic channel resource.
In the above method, the resource collision refers to that the CCE resource for the search space currently distributed is occupied, so that
Current PDCCH resource can not distribute, but there are also PDCCH resources.
What needs to be explained here is that traffic channel resource here will include after introducing PC5 mouthfuls of V2V business
PUSCH, PDSCH, PSSCH channel resource.
If step 102, currently without remaining PDCCH resource, and at least one user for having distributed resource meet it is pre-
If resource reallocation condition then by resource redistribution process be to meet the resource using remaining traffic channel resource
The user of reallocation condition distributes traffic channel resource；The resource reallocation condition is to have the business and correspondence of unallocated resource
Traffic channel resource currently have residue.
Here, different from existing scheme institute, after the resource allocation in step 101, it will be considered that continue industry
The distribution of business channel resource, the distribution without being off resource.It has exhausted in PDCCH resource (i.e. currently without remaining PDCCH
Resource) in the case where, for having been allocated for the user of PDCCH resource, if it has the business of unallocated resource and corresponding industry
Business channel resource currently has residue, just needs through resource redistribution process, continuing with remaining traffic channel resource is it
Distribute traffic channel resource.In this way, the traffic channel resource of current residual can be made full use of, avoid due to not remaining
PDCCH resource and cause traffic channel resource that can not distribute the generated wasting of resources, UE the problem of transmission efficiency is low.
Preferably, specifically can realize that one is according to UE priority using two ways for resource redistribution process
All business whole primary distributions to be allocated of each UE are completed, another kind is that each traversal UE is only that current priority is highest
The traffic assignments resource of resource to be allocated may may require that the process of repeatedly traversal UE under which.Specifically, can use down
State two methods realization:
The implementation method one of the resource redistribution process:
According to the descending of User Priority, traversal meets the user of the resource reallocation condition, utilizes current residual
Traffic channel resource is the corresponding traffic channel resource of all traffic assignments of the current unallocated resource of user, until all
Traffic channel resource exhausts.
The implementation method two of the resource redistribution process:
Step x1, the user that will meet the resource reallocation condition in the user for having distributed resource divides again as resource
With user.
Step x2, for current each resource reallocation user, the highest of the business of the unallocated resource of the user is excellent
First grade, the User Priority current as the user.
Step x3, the resource reallocation user is traversed according to the descending of User Priority, reallocates and uses for the resource
The highest priority traffic of the unallocated resource at family, distributes corresponding traffic channel resource.
If step x4, exiting the resource redistribution process currently without available traffic channel resource；Otherwise,
If at least one current user for having distributed resource meets the resource reallocation condition, otherwise return step x1 is exited
The resource redistribution process.
Through the above scheme it can be seen that the present invention after first time resource allocation, continues with after introducing SL business
Remaining traffic channel resource carries out the distribution of resource, can obtain following technical effect:
1, PDCCH control channel resource and Uu mouthfuls, the matching of PC5 port service channel resource are fully considered, is Uu mouthfuls and PC5
Port service carries out resource allocation, improves the level of resources utilization and UE efficiency of transmission.
2, avoid because introduce PDCCH resource after SL business it is limited caused by the PUSCH/PDSCH/PSSCH wasting of resources, improve
The resource utilization of PUSCH/PDSCH/PSSCH.
3, not only resource can be distributed for the highest priority traffic of UE, or the other lower-priority traffics of the UE
Resource is distributed, the efficiency of transmission of UE is improved.
Fig. 2 is a kind of resource allocation device structural schematic diagram corresponded to the above method, as shown in Fig. 2, the device packet
It includes:
First allocation unit, for user to be dispatched for each of current dispatching cycle, according to the business of the user
Highest priority, determine User Priority；The user to be dispatched is traversed according to the descending of User Priority, to be described wait adjust
The highest priority traffic for spending user distributes corresponding traffic channel resource；The business includes Uu port service and PC5 port service.
Reallocation unit is used for after the first allocation unit completes resource allocation, if provided currently without remaining PDCCH
Source, and at least one user for having distributed resource meets preset resource reallocation condition, then passes through resource redistribution process, benefit
It is the user's distribution traffic channel resource for meeting the resource reallocation condition with remaining traffic channel resource；The resource is again
Distributive condition is to have the business of unallocated resource and corresponding traffic channel resource currently has residue.
Preferably, first allocation unit, for distributing phase in the highest priority traffic for the user to be dispatched
When the traffic channel resource answered, if the user to be dispatched currently traversed has available PDCCH resource, and have with the user most
The corresponding traffic channel resource of high-priority service then distributes corresponding PDCCH resource and traffic channel resource for the user；Such as
Resource collision occurs for the available PDCCH resource for the user to be dispatched that fruit currently traverses, then abandons the resource allocation to the user；Such as
Fruit then terminates the traversal currently without available traffic channel resource.
Preferably, the resource redistribution process includes:
X1, the user that will meet the resource reallocation condition in the user for having distributed resource reallocate as resource and use
Family；
X2, for current each resource reallocation user, by the highest priority of the business of the unallocated resource of the user,
The User Priority current as the user；
X3, the resource reallocation user is traversed according to the descending of User Priority, is the resource reallocation user's
The highest priority traffic of unallocated resource distributes corresponding traffic channel resource；
If x4, currently without available traffic channel resource, terminate the resource redistribution process；Otherwise, if
At least one current user for having distributed resource meets the resource reallocation condition, then return step x1, otherwise, terminates described
Resource redistribution process.
Preferably, the resource redistribution process includes:
According to the descending of User Priority, traversal meets the user of the resource reallocation condition, utilizes current residual
Traffic channel resource is the corresponding traffic channel resource of all traffic assignments of the current unallocated resource of user, until all
Traffic channel resource exhausts.
In conclusion the above is merely preferred embodiments of the present invention, being not intended to limit the scope of the present invention.
