Embodiment one
With reference to Fig. 2, show the flow chart of steps according to a kind of timeslot scheduling method of the embodiment of the invention one.
The timeslot scheduling method of the present embodiment may further comprise the steps:
Step S202: the base station judges whether the data volume of downlink data waiting for transmission is less than or equal to setting threshold, if, execution in step S204 then; If not, execution in step S210 then.
In this step, the base station judges whether the data volume of the downlink data of HSDPA business waiting for transmission is small data quantity, also, whether is less than or equal to setting threshold in the TD-SCDMA system.Wherein, setting threshold can suitably be set according to actual conditions by those skilled in the art, take the volume of transmitted data that is not more than a time interval resource as principle.
Step S204: if the data volume of downlink data waiting for transmission is less than or equal to setting threshold, the CQI(Channel Quality Indicator that feeds back according to terminal corresponding to downlink data waiting for transmission of base station then, CQI) and transmittability corresponding to the actual physical resources of base station physical layer, be terminal distribution the first time interval resource.
The transmittability corresponding to actual physical resources according to the CQI of terminal of this step, for the realization of terminal distribution the first time interval resource can be with reference in the existing TD-SCDMA system, the distributing slot resources of HSDPA business realizes, is not described in detail in this.
Step S206: pregenerated random offset value is used in the base station, and the first time interval resource that distributes is adjusted into the second time interval resource.
Wherein, the random offset value is generated before carrying out distributing slot resources by the base station, and this random offset value is less than the number of the assignable time slot of this timeslot scheduling of base station.
The base station is adjusted into the second time interval resource with the first time interval resource after using random offset value and the first time interval resource to carry out suitable computing.Therefore, the first time interval resource may be different time slots with the second time interval resource, also may be identical time slot.
Step S208: the base station dispatches the second time interval resource to terminal, carries out the transmission of downlink data for terminal, finishes this distributing slot resources and scheduling.
Step S210: the CQI that feed back according to terminal corresponding to downlink data waiting for transmission the base station and the transmittability corresponding to actual physical resources of base station physical layer, be the terminal distribution time interval resource, and this time interval resource dispatched the transmission of carrying out downlink data to terminal, finish this distributing slot resources and scheduling.
The present embodiment provides the timeslot scheduling scheme of HSDPA business in a kind of TD-SCDMA system, and the base station is terminal distribution the first time interval resource according to existing dispatching distribution scheme at first in the data volume of downlink data waiting for transmission hour; Then, on the basis of the first time interval resource, use pregenerated random offset value that the first time interval resource is adjusted, be adjusted into the second time interval resource; This second time interval resource dispatching distribution is used to terminal, thereby realized the STOCHASTIC CONTROL of the distributing slot resources of HSDPA business in the TD-SCDMA system.The scheme of the present embodiment is by the distribution of randomization time interval resource, can effectively alleviate distributing slot resources and concentrate, and is single or part time interval resource acquisition frequency is larger, and then causes disturbing larger problem with time slot.By the present embodiment, can release portion time-division slot resource frequently take the descending with the concentrated situation of time slot interference of generation; Avoid descending interference to concentrate the possibility that business is exerted an influence, improved the HSDPA quality of service; With respect to complicated modification Slot Allocation Algorithm, the present embodiment is processed fast, affects less.
Embodiment two
With reference to Fig. 3, show the flow chart of steps according to a kind of timeslot scheduling method of the embodiment of the invention two.
The timeslot scheduling method of the present embodiment may further comprise the steps:
Step S302: the base station judges whether the BRU of downlink data waiting for transmission is less than or equal to 16, if, execution in step S304 then; If not, execution in step S312 then.
In the present embodiment, whether small data quantity data of downlink data waiting for transmission are judged by the BRU that judges downlink data waiting for transmission in the base station.When BRU was less than or equal to 16, a time slot can be finished the transmission of downlink data, therefore, can determine when BRU is less than or equal to 16, and downlink data waiting for transmission is the small data quantity data.By judging that BRU judges data volume size waiting for transmission, realizes simply save and realize cost, and judgement speed being fast.
But, it should be understood by those skilled in the art that to data whether the judgement of small data quantity data be not limited to this, other suitable judgment mode is applicable equally, as judging byte number, judging space size that takies etc.
Step S304: the base station is at each TTI(Transmit Time Interval, Transmission Time Interval) random offset value of generation.
In general, this random offset value is greater than 0 and less than the natural number of the number of the assignable time slot of this timeslot scheduling.
Need to prove, on the one hand, this step also can perhaps be carried out after the step S306 before step S302, and the random offset value of acquisition is used when needed; On the other hand, this random offset value also can be configured to a suitable value by those skilled in the art, uses in time slot allocation and scheduling process always, and needn't generate at each TTI.But, generate a random offset value at each TTI, realize can effectively guaranteeing Random assignment and the control of time interval resource flexibly and easily.
Step S306: the CQI that feed back according to terminal corresponding to downlink data waiting for transmission the base station and the transmittability corresponding to actual physical resources of base station physical layer are terminal distribution the first time interval resource.
Step S308: the random offset value is used in the base station, and the first time interval resource that distributes is adjusted into the second time interval resource.
When realizing this step, feasible mode comprises: mode one, and the base station is to index value and the summation of random offset value of the first time interval resource; The number of the value after will suing for peace again and the assignable time slot of this timeslot scheduling is carried out complementation; Result after the complementation is as index value, and time slot that will be corresponding with index value is as the second time interval resource; Mode two, the base station is to index value, random offset value and the SFN(System Frame Number of the first time interval resource, System Frame Number) summation; The number of the value after will suing for peace again and the assignable time slot of this timeslot scheduling is carried out complementation; Result after the complementation is as index value, and time slot that will be corresponding with index value is as the second time interval resource.Wherein, use the SFN summation in the mode two, can make time slot allocation more reasonable, further guarantee the randomness of time slot allocation.
For example, the base station available time slot of this scheduling is TS1, TS2, TS3, TS4, TS5 and TS6, corresponding index value is respectively 0,1,2,3,4,5, the random offset value that this TTI generates is set as 3, supposes that the first time interval resource that distributes is TS3, and its corresponding index value is 2, then adopt mode for the moment, remainder (2+3)/6 is 5, take 5 as time slot corresponding to index value as TS6, then the time interval resource of this sub-distribution is TS6; When employing mode two, suppose that SFN is 500, then the remainder behind (2+3+500)/6 is 1, take 1 as time slot corresponding to index value as TS2, then the time interval resource of this sub-distribution is TS2.
Above-mentioned use random offset value is carried out the mode that time interval resource is adjusted, and compared to complicated modification Slot Allocation Algorithm, processes fast, and is less on the impact of existing distributing slot resources and scheduling.
But it should be understood by those skilled in the art that when reality realizes, be not limited to aforesaid way, other appropriate ways is applicable equally, as, directly the index value of the first time slot carried out the complementation of random offset value or ask mould etc.
Step S310: the base station dispatches the second time interval resource to terminal, carries out the transmission of downlink data for terminal, finishes this distributing slot resources and scheduling.
Step S312: the CQI that feed back according to terminal corresponding to downlink data waiting for transmission the base station and the transmittability corresponding to actual physical resources of base station physical layer, be the terminal distribution time interval resource, and this time interval resource dispatched the transmission of carrying out downlink data to terminal, finish this distributing slot resources and scheduling.
By the present embodiment, efficiently solve distributing slot resources and concentrate, single or part time interval resource acquisition frequency is larger, and then cause disturbing larger problem with time slot, can release portion time-division slot resource frequently take the descending of generation and disturb the situation of concentrating with time slot; Avoid descending interference to concentrate the possibility that business is exerted an influence, improved the HSDPA quality of service; With respect to complicated modification Slot Allocation Algorithm, the present embodiment is processed fast, affects less.
Embodiment three
With reference to Fig. 4, show the flow chart of steps according to a kind of timeslot scheduling method of the embodiment of the invention three.
The present embodiment is with in the TD-SCDMA system, and the downlink data of HSDPA business waiting for transmission is the small data quantity data, and being less than or equal to 16 data volume such as BRU is prerequisite, and the terminal in the present embodiment is with UE(User Equipment, subscriber equipment) be example.
The timeslot scheduling method of the present embodiment may further comprise the steps:
Step S402: after the MAC layer of base station is received downlink data from RNC, undertaken being buffered in the base station with Mac_hs PDU data mode after data format transforms by FP.
Step S404: the base station waits Interruption carries out the distributing slot resources scheduling.
Step S406: the base station judges whether that TTI regularly arrives, if, execution in step S408 then; If not, then return step S404.
Step S408: transmittability calculating is carried out with reference to the CQI situation of UE feedback in the base station, for UE distributes original time slot.
Scheduling of resource is carried out by the every TTI of Interruption in the base station, and scheduling reference terminal CQI feedback and the corresponding transmittability of actual physical resources are carried out distributing slot resources.
Step S410: base station Core(kernel) initialization, the random skew initial value that generates.
In the scheduling process, each TTI base station generates a random offset value R, and control R is less than the distributed number of time slots of this timeslot scheduling.
Need to prove, this step also can be carried out before the arbitrary step in step S402-S408.
Step S412: the base station uses the skew initial value that original time slot is adjusted, and obtains the slot offset starting point.
That is, obtaining the starting point of new time slot, also is the index value of new time slot.
As, use formula:
(skew initial value+local frequency current SFN of index+system) % configures timeslot number=slot offset starting point
Obtain the slot offset starting point.Wherein, local frequency index is the index value of original time slot, and the configuration timeslot number is the available time slot number of this time slot allocation, and % represents to ask the mould remainder.
The base station determines that by CQI information the physical resource that needs to distribute is the time slot number, in resource pool, select to distribute afterwards time interval resource, after carrying out time slot allocation by former processing, the skew initial value R addition of the time slot that all have distributed and generation, and downstream arrangements timeslot number (being assignable descending time slot number) done remaining operation, obtain new time slot allocation order.The randomness of R has guaranteed that time slot allocation also possesses randomness, and the distribution of single time slot is completely random then.
Step S414: the base station travels through the TS time slot with the slot offset starting point that calculates, and calculates this time slot and can use code channel resource.
Step S416: the base station is according to time-slot code channel Resource Calculation allowable resource matrix, and finishes the distributing slot resources process.
Step S418: the base station sends downlink data after coupling resource selection to its physical layer.
Subsequent base stations sends being buffered in local Mac_hs PDU data according to resource allocation result, finishes HSDPA scheduled transmission process one time.
The allocation schedule realization of the existing time slot of contrast, if the configuration time slot is in TS3, TS4, the TS5 situation, when adopting the present embodiment to realize slot allocation schedule in the double small district 4UE situation, its simulate effect as shown in Figure 5.Among Fig. 5, oblique wire frame representation allocation result.Can see, behind use the present embodiment, take time interval resource between different districts, the different UEs and can accomplish randomization, and then can avoid the interference concentration phenomenon that frequently takies generation of single time slot.
The present embodiment provides a kind of prioritization scheme of randomization time slot allocation, be used for the downlink resource assigning process take with frequently not simultaneously, simultaneously different frequently as principle with the time slot allocation randomization, the situation that release portion time-division slot high probability takies, and then optimize HSDPA traffic resource assignment process, improve the user and experience.Distribute uneven problem for small data quantity business time-slot in the existing HSDPA resource distribution, the distribution of the randomization time interval resource in the present embodiment, can effectively alleviate distributing slot resources concentrates, same time slot single or that part time interval resource acquisition frequency causes more greatly disturbs larger problem, can effectively avoid descending and disturb the situation of concentrating to occur with time slot.By the present embodiment, can release portion time-division slot resource frequently take the descending with the concentrated situation of time slot interference of generation; Avoid descending interference to concentrate the possibility that business is exerted an influence, improved the HSDPA quality of service; With respect to complicated modification Slot Allocation Algorithm, process faster, affect less.
