Description
Technical field
This application involves the dispatching technique in communication system, in particular to a kind of uplink semi-persistent resource (SPS) user's
Dispatching method.
Background technique
In TDD system, uplink scheduling and transmitting uplink data are carried out in different subframes, wherein uplink scheduling is under
Row subframe carries out.Specifically, for uplink scheduling there are stringent timing requirements, the uplink authorization for passing subframe to specified upstream number is necessary
It is issued in corresponding downlink subframe；Otherwise, the interface-free resources that upper line number passes subframe will have to waste.Currently, carrying out uplink
The subframe of authorization is scheduled according to User Priority sequence.
In existing user scheduling method, uplink and downlink scheduling uses the PDCCH resource of the same TTI.Descending scheduling is wanted
Some essential informations of scheduling system, it is therefore necessary to ensure descending scheduling is gone on smoothly；Uplink authorization can only be in downstream grants
After the completion, it just can be carried out, in most cases, the scheduling time of the shared TTI of uplink and downlink scheduling, scheduling time is once more than
The time restriction of this TTI, all scheduling results will be dropped.
In view of the processing capacity limitation of existing processor, the number of users that a TTI can be dispatched is very limited, PS in public network
Business is relatively more, and the data volume of PS business is bigger, therefore the number of users that single TTI needs to dispatch is fewer, scheduling time pair
Throughput of system is influenced there is no apparent.And in private network system, voice service is relatively more, eats dishes without rice or wine needed for individual voice business
Resource is fewer, it is possible that following situation: in the case where also remaining interface-free resources, since scheduling time is finished, and voice
Business can not be dispatched.Therefore, the specification of voice service is limited to bandwidth of cell and scheduling time simultaneously in private network.
In actual scene, in most cases (subframe of no forward scheduling), single TTI can only dispatch several use to uplink
Family, even if the subframe of forward scheduling, the number of users that can be dispatched is also with regard to more than 10.Once occurred following feelings in actual test
Condition: the uplink scheduling time is exhausted in 8 SPS users of near point, there remains a large amount of interface-free resources at this time.Therefore, big bandwidth
System in, voice service specification is limited to the dispatching of system.
By above situation as it can be seen that in current private network system, the subframe being scheduled is due to scheduling time deficiency, and there are nothings
Method is to user the case where carrying out uplink scheduling；Meanwhile the subframe passed in upper line number, any scheduling is not carried out, system is in number
The dispatching for passing subframe is unable to get sufficient utilization.

Detailed description of the invention
Fig. 1 is the flow diagram of uplink SPS user scheduling method in the embodiment of the present application.
Specific embodiment
In order to which the purpose, technological means and advantage of the application is more clearly understood, the application is done below in conjunction with attached drawing
It is further described.
Implicit authorization has been carried out after activation or reactivation in uplink SPS user.That is, according to SPS mechanism
Principle, activate SPS after, terminal can according to activation SPS when signaling process, in the sky in setting of specific period of sub-frame
Mouthful transmitted over resources data, eat dishes without rice or wine to will no longer be required to issue PDCCH and are authorized.
For activated SPS user, uplink scheduling mainly includes following content: 1) occurring in the channel parameter eated dishes without rice or wine
When variation, the authorization that PDCCH carries out PHICH is re-issued；2) in reactivation and deactivation, base station issues weight to SPS user
Activation and deactivation information；3) relevant information of inside of base station maintenance user scheduling, issues management frame to base band.
1) the in the processing of above-mentioned 3 kinds of uplink schedulings is planted, the case where the configuration variation for the channel parameter eated dishes without rice or wine very
Less, at the time of also, the variation of channel parameter accurately can judge that it comes into force by detecting in advance, and then can sentence in advance
It is disconnected to go out to need again to authorize it.
2) the in the processing of above-mentioned 3 kinds of uplink schedulings is planted, reactivation and deactivated demand are also to sentence in advance
Disconnected.
Above-mentioned the 1) plant and the 2) plant uplink scheduling processing need base station to transmit information to SPS user, it is corresponding to complete
Uplink scheduling, therefore, can only according to timing relationship setting uplink scheduling subframe carry out.
3) the in the processing of above-mentioned 3 kinds of uplink schedulings is planted, the relevant information of maintenance user's scheduling and issued to base band
Management frame belongs to the scheduling behavior of inside of base station, does not need to transmit information to SPS user.Wherein, " the phase of maintenance user's scheduling
Close information " it is not stringent to time requirement, " issuing management frame to base band " is using scheduling as a result, also not high to time requirement.
From the foregoing, it can be seen that in the case where channel parameter of eating dishes without rice or wine does not change, the uplink of non-deactivation or non-reactivation
SPS user, uplink scheduling is not necessarily intended to carry out in corresponding uplink scheduling subframe, by the scheduling resource of uplink scheduling subframe
More for dispatching unscheduled SPS user and carrying out the user for eating dishes without rice or wine to authorize.
It is not changed in channel parameter of eating dishes without rice or wine when carrying out uplink SPS user scheduling in the application based on above-mentioned consideration
In the case of, the scheduling of the uplink SPS user of non-deactivation or non-reactivation is advanceed into transmitting uplink data subframe and is carried out.
It specifically, can be in sky to the corresponding activated uplink semi-persistent resource SPS user of a uplink scheduling subframe A
When mouth channel parameter does not change, the uplink scheduling of the wherein uplink SPS user of non-deactivation and/or non-reactivation mentions
The preceding transmitting uplink data subframe corresponding with the uplink scheduling subframe A to before uplink scheduling subframe A carries out.
Wherein, between uplink scheduling subframe A and the transmitting uplink data subframe of substitution uplink scheduling subframe A progress uplink scheduling
Corresponding relationship, can preset, for example, system default or administrator setting etc..When setting corresponding relationship, a uplink
Data transmission subframes can correspond to one or more uplink scheduling subframes, such as transmitting uplink data subframe B and position can be set
One or more uplink scheduling subframes after subframe B and nearest apart from subframe B are corresponding.
Illustrate the uplink SPS user scheduling method in the application below by a specific embodiment.It is given in the present embodiment
Go out and has carried out the process of uplink scheduling in some transmitting uplink data subframe.Fig. 1 is the dispatching method flow diagram of embodiment,
As shown in Figure 1, this method comprises:
Step 100, start to dispatch on transmitting uplink data subframe X.
Step 101, according to preset corresponding relationship, corresponding uplink scheduling of transmitting uplink data subframe X is obtained
The SPS user chain table of activation of frame.
The corresponding relationship of corresponding relationship in this step, that is, between transmitting uplink data above-mentioned subframe and uplink scheduling subframe,
In this example, it is assumed that transmitting uplink data subframe be located at thereafter, it is corresponding away from a nearest uplink scheduling subframe.This
In, the activation SPS user of a uplink scheduling subframe after acquisition transmitting uplink data subframe X and apart from subframe X recently
Chained list.
Step 102, a user is chosen from the SPS user chain table of activation of acquisition as active user.
Step 103, judge on sub-frame of uplink scheduled in the corresponding uplink scheduling subframe of active user, whether channel parameter
It can change, if so, turning to step 106, otherwise, turn to step 104.
In this step, judge whether channel parameter can changed mode when may is that the PHICH for judging active user
Whether the channel parameter at quarter can change.If can change, all users dispatched in same subframe can be impacted, needed
PHICH authorization is re-started to these SPS users, then turns to step 106；If will not change, step is turned to
104, per user judges whether to carry out uplink scheduling in transmitting uplink data subframe.
Step 104, judge whether active user needs reactivation or deactivation, if it is, step 107 is turned to, it is no
Then, step 105 is turned to.
Specifically, if active user needs reactivation or deactivation, base station is needed to send downlink letter to SPS user
Breath, then just needing to turn to step 107, in the uplink scheduling subframe scheduling active user of timing requirements.If active user is not
Reactivation is needed, does not also need to deactivate, then going to step 105, carries out active user's in transmitting uplink data subframe
Scheduling, to reserve the scheduling that more resources carry out non-SPS user etc. in uplink scheduling subframe.
Step 105, uplink scheduling is carried out to active user, and turns to step 108.
Here be scheduling to the relevant information of maintenance schedule, and issue management frame to base band when base band is needed.
Step 106, terminate in transmitting uplink data subframe not to having activated the user in SPS user chain table to be scheduled
This process.
When channel parameter of eating dishes without rice or wine changes, this step is executed.When changing due to channel parameter of eating dishes without rice or wine, for same son
All users of frame scheduling can impact, therefore once detect channel parameter of eating dishes without rice or wine and will change, same
All users (having activated all users in SPS user chain table) of subframe scheduling cannot be in transmitting uplink data subframe tune
Degree requires to carry out uplink scheduling to these users until the uplink scheduling subframe of timing requirements.
Step 107, active user is not scheduled in transmitting uplink data subframe.
As previously mentioned, need base station to photos and sending messages under SPS user if active user needs to deactivate or reactivation,
It is thus impossible to carry out corresponding scheduling operation in uplink transmission subframe, and need still in the uplink scheduling of timing requirements
Subframe carries out corresponding dispatch deal.
Step 108, using the next user activated in SPS user chain table as active user, return step 103, directly
To the user that can not dispatch or time-out of current TTI scheduling time.
By the processing of previous step 103~107, the user of a non-deactivation and non-reactivation is passed in upstream data
Defeated subframe is dispatched, next, successively identical processing is carried out to the other users in chained list, until all in chained list
User is disposed, or until current TTI scheduling time time-out.
In the present embodiment, what is carried out so that a transmitting uplink data subframe is corresponding with a uplink scheduling subframe as an example is said
It is bright, in fact, as previously mentioned, transmitting uplink data subframe can be with multiple uplink scheduling subframes pair when establishing corresponding relationship
It answers, in this case, it is necessary to which multiple the multiple of uplink scheduling subframe corresponding to transmitting uplink data subframe have activated SPS to use
User in the chained list of family carries out the processing in above step 103~107, or until current TTI scheduling time time-out.
So far, the method flow in the present embodiment terminates.
By the specific implementation of above-mentioned the application as it can be seen that in the application, the time for making full use of line number to pass subframe is carried out
Row SPS user scheduling, so that it is guaranteed that there is more time scheduling SPS users, improves the specification of voice service under big bandwidth；Together
When, the scheduling time requirement to uplink authorization subframe is reduced, the number of users that the system of improving can dispatch is conducive to promote system
It unites the specification of voice service, equally also wins more scheduling times for the more stringent non-SPS user of time requirement, it can be with
Dispatch more non-SPS users.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent substitution, improvement and etc. done be should be included within the scope of the present invention.
