Description

High-speed downlink packet access users dispatching method and base station

Technical field

The present invention relates to mobile communication technology, particularly relate to a kind of high-speed downlink packet access users dispatching method and base station.

Background technology

At present, TD SDMA (Time Division-Synchronous Code Division Multiple Access; Referred to as: TD-SCDMA) high-speed slender body theory (the High Speed Downlink Packet Access of system; Referred to as: HSDPA) business adopts identical networking substantially.HSDPA business is by high-speed downlink shared channel (High-Speed Downlink Shared Channel; Referred to as: HS-DSCH) carry actual user data, HS-DSCH is a kind of transmission channel; In physical layer, HS-DSCH will be mapped to high-speed physical downlink shared channel (HS-PDSCH) (High-Speed Physical Downlink Shared Channel; Referred to as: HS-PDSCH).Although HS-PDSCH has wave beam forming, HS-PDSCH not power controls, and user terminal (User Equipment; Referred to as: UE) generally only have a reception antenna, also cannot do interference to eliminate, therefore when adjacent cell UE and this community UE wave beam forming in the same direction time, the HSDPA business of adjacent cell UE and the HSDPA business of this community UE can produce co-channel interference, especially when adjacent cell UE and this community UE is when the edge of respective community, the impact that this co-channel interference is brought can be even more serious.

In order to solve the problem of co-channel interference, prior art mainly adopts following several method to dispatch UE at present: a kind of method divides into outer ring (cell edge) and inner ring (center of housing estate) by little, outer ring uses the subset of cell carrier frequencies, inner ring uses the complete or collected works of cell carrier frequencies, the outer ring of neighbor cell uses different carrier frequency, this mode is by being that alien frequencies avoids interference by the same frequency question variation of cell edge, but carrier switch frequently can be brought under UE mobile status, add risk of dropped calls.Another kind method is CQI (the Channel Quality Indicator that base station (NodeB) utilizes UE to feed back; Referred to as: the quality of reception situation of eating dishes without rice or wine CQI) determining UE side, when the quality of reception of eating dishes without rice or wine of UE side is better, reducing the transmitting power of HS-PDSCH, reduce co-channel interference, but this mode can reduce the maximum download rate of UE by reducing transmitting power.Another method is that base station is dispatched the user being in cell edge with certain random chance, stagger to the scheduling of user on carrier frequency same in neighbor cell to a certain extent by this way, reduce co-channel interference, but the extreme that this method can bring interference unstable increases, and increases Packet Error Ratio.

As seen from the above analysis, prior art, while reduction co-channel interference, can produce various deficiency again, not can solve problem of co-channel interference.

Embodiment

For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.

The flow chart of the HSDPA user scheduling method that Figure 1A provides for one embodiment of the invention.As shown in Figure 1A, the method for the present embodiment comprises:

Step 101, when the transmission period of the HS-PDSCH of current scheduling be allocate in advance to the priority scheduling period of the carrier wave that is scheduled of the community that is scheduled time, base station to being scheduled of the community that is scheduled carrier wave treats that dispatched users carries out normal consistency by the principle that edge customer is preferential.

Before concrete enforcement this step 101, for the carrier wave of certain frequency, wireless controller (Radio Network Controller; Referred to as: RNC) can according to the quantity of the community of this frequency of administrative use carriers carry HSDPA business and community neighbor information (i.e. the situation of neighbor cell), is divided into the scheduling slot that multiple isometric and cycle is alternately arranged the scheduling time of this frequency carrier wave, and for this frequency allocation of carriers scheduling slot marked off of each community is as priority scheduling period of this frequency carrier wave of each community.Then, the priority scheduling period of distributing on this frequency carrier wave for the community under each community under base station coverage and other base station coverage adjacent with base station coverage Xia Ge community can be handed down to the base station at place, each community by RNC.That is, base station can know in advance its cover under the priority scheduling period of certain community on certain frequency carrier wave and the priority scheduling period of other communities adjacent with this community on the carrier wave (with carrier wave frequently) of same frequency.

The division of above-mentioned scheduling slot and the principle of distribution are make the priority scheduling period of any two neighbor cells on this frequency carrier wave all not identical.According to 4 famous look theorems, to be divided into 4 scheduling slots the scheduling time of certain frequency carrier wave just enough for RNC in theory, if each community be by etc. large hexagonal manner arrangement, then only need be divided into 3 scheduling slots just enough.

Wherein, RNC, also can by the high speed information shared channel of adjacent area on this frequency carrier wave (High-Speed Shared Information Channel while the priority scheduling period of the adjacent area of each community on certain frequency carrier wave is handed down to base station, place, each community; Referred to as: HS-SICH) information (such as: intermediate pilot (midamble) the code numbering of place time slot, use and intermediate pilot code skew (midamble shift)) is handed down to base station in the lump.

For the frequency carrier wave of any one carrying HSDPA business, RNC carries out above-mentioned process.

Wherein, the scheduling time of a certain frequency carrier wave refers to that the HS-PDSCH that the carrier wave of this frequency is dispatched is in the subframe of air interface transmission, identifies with the continuous subframes of loop cycle number.Because current TD-SCDMA base station uses global positioning system (Global Positioning System; Referred to as: GPS) time service, same time point, the subframe numbers of each carrier wave in all base stations of the whole network is identical.RNC can be the scheduling slot that multiple length is identical according to the transmission subframe numbers of HS-PDSCH of scheduling sub-frame division of being eated dishes without rice or wine by continuous print, and wherein each scheduling slot comprises same number and continuous print scheduling subframe.Such as: the cycle supposing subframe numbers is K, supposes to mark off T scheduling slot, each scheduling slot comprises continuous print M scheduling subframe, then scheduling slot can be numbered by RNC from 0, and to be the scheduling slot that the subframe of n belongs to be subframe numbers when the cycle K of subframe numbers is not the integral multiple of M × T, the length of that scheduling slot at cycle boundary place can be less than M, and this does not affect the validity of the embodiment of the present invention.Describing below supposes that K is the integral multiple of M × T, such as: suppose K=512, M=4, so the scheduling time of this carrier wave is just divided into 3 scheduling slot (T0 by T=3, T1, T2), and each scheduling slot comprises 4 scheduling subframes, be the schematic diagram to the scheduling slot that continuous subframes marks off as shown in Figure 1B.Based on the scheduling slot that Figure 1B divides, Fig. 1 C shows the execution mode of the priority scheduling period that a kind of community for hexagonal array is distributed on certain frequency carrier wave, is specially: the priority scheduling period that community C7 distributes on certain frequency carrier wave is T0; The priority scheduling period that the community C1-community C6 adjacent with community C7 distributes successively on certain frequency carrier wave is T2, T1, T2, T1, T2, T1.

In the present embodiment, if the HSDPA user of base station to the carrier wave of a community frequency dispatches, described community is called as the community that is scheduled, and the carrier wave of described frequency is called as the carrier wave that is scheduled.Before base station is dispatched the community that is scheduled, RNC is according to quantity and the community neighbor information of the community of the same frequency carriers carry HSDPA business of this carrier wave that is scheduled of administrative use, this be scheduled scheduling time of carrier wave is divided into multiple isometric scheduling slot, and for using each cell allocation scheduling slot of this carriers carry HSDPA business that is scheduled as its priority scheduling period on the same frequency carrier wave of the carrier wave that is scheduled, and wherein any two adjacent communities are different in priority scheduling period that this is scheduled on carrier wave.And, RNC gives base station by for be scheduled community and issuing in the priority scheduling period that this is scheduled on carrier wave of neighbor cell allocation, for base station to being scheduled of being scheduled carrier wave treats that dispatched users is carried out scheduling and laid the first stone based on the scheduling slot marked off and priority scheduling period of distributing to each neighbor cell.

When the be scheduled carrier wave of certain subframe to the community that is scheduled when base station in certain scheduling slot is dispatched, can judge in the priority scheduling period on carrier wave that is scheduled according to the neighbor cell known in advance that whether the period (namely transmitting the period) at the transmission subframe place of current dispatched HS-PDSCH is the priority scheduling period of the carrier wave that is scheduled of community of being scheduled.If judged result is yes, then perform this step 101, namely preferential according to edge customer principle carries out normal consistency; If judged result is no, then perform step 102.Wherein, the principle that base station is preferential according to edge customer is carried out normal consistency and is mainly referred to and to be scheduled the edge customer of community in the priority scheduling in dispatched users treated be scheduled on carrier wave of the community that is scheduled.Edge customer refers to the user being in cell edge.

Step 102, be when being scheduled the non-preferential scheduling slot of the carrier wave that is scheduled of community when the transmission period of the HS-PDSCH of current scheduling, base station to being scheduled of the community that is scheduled carrier wave treats that dispatched users is by the preferential principle of central user, and carries out adaptability scheduling according to the beam direction treating dispatched users be scheduled on carrier wave of schedule information before current scheduling in fixed time length of the same frequency carrier wave of the community adjacent with the community that is scheduled detected and the community that is scheduled.

Wherein, the same frequency carrier wave of adjacent with the community that is scheduled community refers to that the carrier wave that is scheduled with the community that is scheduled has the carrier wave of same frequency.In order to simplified characterization, " the same frequency carrier wave of the community adjacent with the community that is scheduled " is referred to as " adjacent area is with frequently ".In specific implementation process, when the transmission time of the HS-PDSCH of current scheduling is, when being scheduled the non-preferential scheduling slot of the carrier wave that is scheduled of community, show that this scheduling slot is the priority scheduling period that other communities are scheduled on carrier wave at this.When the transmission period of base station to the HS-PDSCH of current scheduling, the community that is non-preferential scheduling slot was dispatched, first priority scheduling central user, and then with being scheduled of the schedule information frequently before current scheduling in fixed time length and this community that is scheduled carrier wave treats that the beam direction of dispatched users is from treating to select a user dispatched users, carries out adaptability scheduling to this user according to adjacent area.

In the present embodiment, schedule information mainly refers to the beam direction of adjacent area with the upper scheduled user of frequency, usually also can comprise the HS-SICH signal strength signal intensity of scheduled user, dispatch the information such as the period of generation.

Be when being scheduled the non-preferential scheduling slot of the carrier wave that is scheduled of community in the transmission period of the HS-PDSCH of current scheduling, the user of other communities relatively, the edge customer be scheduled in community has had certain priority, thus the present embodiment in this case priority scheduling central user can ensure to carry out equity dispatching to user each in the community that is scheduled.

The HSDPA user scheduling method of the present embodiment, be priority scheduling period corresponding to each cell allocation in advance, base station judges that whether current scheduling is the priority scheduling period of the carrier wave that is scheduled of community of being scheduled, if, then carrier wave treated that dispatched users carries out normal consistency to being scheduled of the community that is scheduled, if not, then according to the schedule information before the neighbor cell of the community that is scheduled and the beam direction treating dispatched users be scheduled on carrier wave of community of being scheduled, carrier wave treats that dispatched users carries out adaptability scheduling in the community that is scheduled being scheduled, make to only have the priority scheduling period to be carrier wave treats that dispatched users is by normal consistency being scheduled in the community of this period at a scheduling slot, other communities carry out adaptability scheduling according to the schedule information before respective neighbor cell and this community at the beam direction treating dispatched users on carrier wave that is scheduled, reduce the co-channel interference between each neighbor cell on the one hand, overcome the various defects that prior art exists on the other hand.

Be when being scheduled priority scheduling period of the carrier wave that is scheduled of community when the transmission period of the HS-PDSCH of current scheduling, the present embodiment provides a kind of step 101, and namely the treat preferred embodiments that dispatched users carry out normal consistency that be scheduled carrier wave on of base station to the community that is scheduled is: whether base station judge to be scheduled the treating on carrier wave that be scheduled of community exists the edge customer needing scheduling in dispatched users.When the edge customer of the existence needs scheduling in dispatched users on carrier wave that is scheduled of the community that is scheduled, base station preferentially to being scheduled of the community that is scheduled carrier wave treats that the edge customer needing in dispatched users to be scheduled is dispatched, and the HS-PDSCH corresponding with the edge customer be scheduled launches with pre-configured transmitting power.Comparatively preferably, base station can according to the priority of each edge customer, and the edge customer that prioritizing selection priority is high is dispatched.When the edge customer in dispatched users be scheduled on carrier wave of the community that is scheduled all has been scheduled or non-flanged user needs to be scheduled, base station to being scheduled of the community that is scheduled carrier wave treats that the central user in dispatched users is dispatched, and the HS-PDSCH corresponding with the central user be scheduled launches with pre-configured transmitting power.Wherein, central user refers to the user being in center of housing estate.Comparatively preferably, base station can according to the priority of each central user, and the central user that prioritizing selection priority is high is dispatched.

In specific implementation process, base station can be scheduled the edge customer of community or central user according to the dispatched users (i.e. HSDPA user) for the treatment of be scheduled on carrier wave of Serving cell adjacent cell path loss difference (SNPL) of reporting of user or other this community that is scheduled of means identification in advance.Identify treat dispatched users be central user or edge customer while, base station also can treat central user in dispatched users respectively according to priority and edge customer sorts, and forms central user queue to be scheduled and edge customer queue.When edge user scheduling, base station is dispatched from the edge customer that edge customer queue medium priority is high, if the edge customer that priority is high does not have data to send the edge customer just dispatching next priority-level, until arrive the afterbody of this edge customer queue or without scheduling resource, described scheduling resource comprises HS-SCCH/HS-SICH control channel and HS-PDSCH resource pool etc.In like manner, when to center user scheduling, base station is dispatched from the edge customer that center Subscriber Queue medium priority is high, if the edge customer that priority is high does not have data to send just dispatch the central user of next priority-level, until arrive this central user queue afterbody or without scheduling resource.

Seen from the above description, the transmission period for the HS-PDSCH of current scheduling is when being scheduled priority scheduling period of the carrier wave that is scheduled of community, base station directly to being scheduled of the community that is scheduled carrier wave treats that dispatched users is dispatched with the transmitting power of pre-configured HS-PDSCH according to the preferential principle of edge customer, can ensure the maximum speed of download of user terminal.

The present embodiment provides a kind of embodiment of step 102 to comprise: whether base station first judge to be scheduled the treating on carrier wave that be scheduled of community exists the central user that needs are scheduled in dispatched users; If existed, then preferential carrier wave treated that the central user that the needs in dispatched users are scheduled is dispatched to being scheduled of the community that is scheduled; If there is no, then base station to being scheduled of the community that is scheduled carrier wave treats that the edge customer in dispatched users is dispatched.The present embodiment, in the non-preferential scheduling slot priority scheduling central user of the community that is scheduled, can realize the equity dispatching to central user and edge customer.

When base station judge to be scheduled community the carrier wave that is scheduled on have a central user needing scheduling time, from wherein selecting a central user as current candidate dispatched users, then further according to the schedule information of same frequency carrier wave before current scheduling in fixed time length of the community adjacent with the community that is scheduled detected, before judging current scheduling, in fixed time length, adjacent area was scheduled with the user whether frequency exists beam direction identical or close with the beam direction of this current candidate dispatched users.Wherein, the time span of specifying before current scheduling can be preassigned some subframes, such as 12 subframes.If in fixed time length, adjacent area was scheduled with frequency does not exist the user identical with the beam direction of current candidate dispatched users before current scheduling, base station is dispatched the central user as current candidate dispatched users, the HS-PDSCH corresponding with current candidate dispatched users launches with pre-configured transmitting power, thus ensures the maximum speed of download of user terminal.If in fixed time length, adjacent area was scheduled with frequently above there is the user identical with the beam direction of current candidate dispatched users before current scheduling, base station is dispatched current candidate dispatched users, and the HS-PDSCH corresponding with current candidate dispatched users launches with the transmitting power after reducing; That is, in this case in order to reduce the interference to adjacent area, base station suitably can reduce the transmitting power of HS-PDSCH.The performance brought for the transmitted power reducing HS-PDSCH central user reduces can not be clearly.Do not limit the concrete numerical value and method that reduce transmitting power in the present embodiment, can depending on real needs.From the angle reduced adjacent area interference, the power reduction threshold value set by can simply the transmitted power of current HS-PDSCH being reduced, this power reduction threshold value can be set as 5dB.The performance of collateral security central user is set out, and the mode of more complicated power control at a slow speed can be adopted to reduce the transmitted power of HS-PDSCH gradually to appropriate level.

In the above-described embodiment, base station can be scheduled the edge customer of community or central user according to the dispatched users (i.e. HSDPA user) for the treatment of be scheduled on carrier wave of the SNPL of reporting of user or other this community that is scheduled of means identification equally in advance, and the central user identified and edge customer is carried out sorting respectively according to priority and be stored into respectively in central user queue and edge customer queue.Based on this, base station specifically can according to the priority of central user, and the central user that prioritizing selection priority is higher from the Subscriber Queue of center, as current candidate dispatched users, is namely dispatched central user according to priority order from high to low successively.

When base station judge to be scheduled the central user in dispatched users be scheduled on carrier wave of community be all scheduled or non-stop layer user needs scheduling time, then base station starts the edge customer treated in dispatched users and dispatches, concrete, first base station selects an edge customer as current candidate dispatched users from the treating carrier wave that be scheduled of the community that is scheduled in dispatched users, then according to the schedule information of same frequency carrier wave before current scheduling in fixed time length of the community adjacent with the community that is scheduled detected, before judging current scheduling, in fixed time length, adjacent area was scheduled with the user whether frequency exists beam direction identical or close with the beam direction of this current candidate dispatched users.If in fixed time length, adjacent area was scheduled with frequently above there is the user identical or close with the beam direction of current candidate dispatched users before current scheduling, base station, before dispatching the edge customer as current candidate dispatched users, judges that further whether the transmission period of the HS-PDSCH of current scheduling is adjacent area with priority scheduling period (namely judging that whether the transmission period of the HS-PDSCH of current scheduling is priority scheduling period of the scheduled user place cell carrier that beam direction is identical or close with the beam direction of current candidate dispatched users) of frequency.If judged result is no, illustrate that now current candidate dispatched users produces certain interference to this adjacent area with the user frequently, but owing to not being the priority scheduling period of this adjacent area with frequency, to go forward side by side the low interference now of a step-down to make full use of dispatcher, base station is dispatched current candidate dispatched users with predetermined probabilities, and the HS-PDSCH corresponding with current candidate dispatched users launches with pre-configured transmitting power.If judged result is yes, illustrate that now current candidate dispatched users can produce interference to this adjacent area with the user frequently, in order to reduce adjacent area with the interference frequently within its priority scheduling period, scheduling current candidate dispatched users is abandoned in base station, and carrier wave treats that next edge customer in dispatched users is as current candidate dispatched users, to attempt dispatching next edge customer in being scheduled of community of selecting to be scheduled.Wherein, to the same scheduling process to a upper edge customer of the scheduling process of next edge customer.Namely after next edge customer is chosen as current candidate dispatched users by base station, re-execute the schedule information of same frequency carrier wave before current scheduling in fixed time length according to the community adjacent with the community that is scheduled detected, whether the same frequency carrier wave of community adjacent with the community that is scheduled in fixed time length before judging current scheduling exists operation and subsequent operation that the identical or close user of the beam direction of beam direction and current candidate dispatched users was scheduled, instruct till scheduling is completed to this next edge customer.Describedly complete scheduling and comprise and carry out dispatching or abandon scheduling.Wherein, beam direction is close refers to that two beam direction differences are less than preset direction threshold value, if use arrival direction (Direction Of Arrival; Referred to as: DOA) represent beam direction, direction threshold value can be set to the value of 0 ~ 90 degree, if use beamforming vector to represent beam direction, the difference of two beam directions can be weighed with they beamforming vector normalized correlations, and direction threshold value can be set to the value of 0 ~ 1.If in fixed time length, adjacent area was scheduled with frequency does not exist the user identical or close with the beam direction of current candidate dispatched users before current scheduling, base station is dispatched the edge customer as current candidate dispatched users, and the HS-PDSCH corresponding with current candidate dispatched users launches with pre-configured transmitting power.

Further, in the above-described embodiment, base station also can be dispatched according to priority edge user.Such as: base station can select edge customer as current candidate dispatched users successively according to priority order from high to low from edge customer queue, realizes the scheduling of edge user.

In the above-described embodiment, no matter be that edge user carries out dispatching or dispatching central user, before base station all needs to perform and judges current scheduling further, in fixed time length, whether the same frequency in adjacent area exist the operation that the beam direction user identical with the beam direction of current candidate dispatched users was scheduled.Therefore the present embodiment separately provides a kind of execution mode of step 102 to be: base station first according to the adjacent area detected with the schedule information frequently before current scheduling in fixed time length, to the community that is scheduled to be scheduled on carrier wave each treats that dispatched users judges, before judging current scheduling, in fixed time length, with this whether having that beam direction and the choosing on carrier wave that be scheduled of the community that is scheduled carry out judgement operation on frequently, adjacent area treats that the user that the beam direction of dispatched users is identical or close was scheduled.Like this, base station will know the information whether each scheduled user exists the identical user of beam direction and be scheduled in adjacent area in advance.

Then, whether base station judge further to be scheduled the treating on carrier wave that be scheduled of community exists the central user needing to be scheduled in dispatched users; When judged result be scheduled community be scheduled on carrier wave in dispatched users, there is the central user needing to be scheduled time, base station preferentially to being scheduled of the community that is scheduled carrier wave treats that the central user needing in dispatched users to be scheduled is dispatched.Concrete, base station combines each central user known in advance simultaneously in adjacent area, whether there is the information that the identical user of beam direction was scheduled, and dispatches each central user.This process, with the scheduling process of above-described embodiment to central user, does not repeat them here.When dispatching central user when base station, launch with pre-configured transmitting power according to the HS-PDSCH corresponding with the central user be scheduled being scheduled central user simultaneously.Wherein, base station can according to when judged result be scheduled community be scheduled on carrier wave in dispatched users, there is not the central user needing to be scheduled time, base station to being scheduled of the community that is scheduled carrier wave treats that the edge customer in dispatched users is dispatched.Concrete, base station combines each edge customer known in advance simultaneously in adjacent area, whether there is the information that the identical user of beam direction was scheduled, and dispatches each edge customer.This process, with the scheduling process of above-described embodiment edge user, does not repeat them here.

The flow chart of the HSDPA user scheduling method that Fig. 2 provides for another embodiment of the present invention.The present embodiment realizes based on Figure 1A illustrated embodiment, and as shown in Figure 2, the method for the present embodiment comprises:

Step 200, base station judge whether the transmission period of the HS-PDSCH of current scheduling is allocate the priority scheduling period to the carrier wave that is scheduled of the community that is scheduled in advance; If judged result is yes, perform step 201; If judged result is no, perform step 202.

Step 201, base station to being scheduled of the community that is scheduled carrier wave treat that dispatched users carries out normal consistency by the principle that edge customer is preferential, and after scheduling completes end operation.

The HS-SICH of the same frequency carrier wave of step 202, pair community adjacent with the community that is scheduled, base station detects and channel estimating, obtains the schedule information of the same frequency carrier wave of the community adjacent with the community that is scheduled, and then performs step 203.

Wherein, schedule information mainly comprises the information such as the beam direction of the scheduled user on the same frequency carrier wave of the community adjacent with the community that is scheduled and the transmission period of the HS-PDSCH corresponding with scheduled user.

Base station obtains schedule information process and mainly comprises: first the neighbor cell that issues according to RNC, base station is with the HS-SICH place time slot of carrier wave, the midamble code of use and midamble shift frequently, in each subframe, with HS-SICH frequently, channel estimating is carried out to adjacent area, thus determine that adjacent area is with the direction of the scheduled user on frequency relative to the antenna in cell that is scheduled in each scheduling slot, should be relative to the direction of the antenna in cell that is scheduled the beam direction that the same scheduled user frequently in adjacent area is subject to the descending interference of the carrier wave that is scheduled from the community that is scheduled.The descending interfering beam direction of the same scheduled user frequently in adjacent area that in nearest fixed time length, each subframe detects is recorded for follow-up scheduling in base station.In follow-up scheduling by the downlink wave beam direction of the current candidate dispatched users of the carrier wave that is scheduled of the community that is scheduled and adjacent area with scheduled user frequently descending interfering beam direction compared with, when two beam direction differences are less than preset direction threshold value, determine that the current candidate dispatched users of adjacent area with scheduled user frequently and the community that is scheduled is on identical or close beam direction, otherwise, determine not at identical or close beam direction.

Step 203, base station to being scheduled of the community that is scheduled carrier wave treat that dispatched users is by the preferential principle of central user, and according to schedule information before current scheduling in fixed time length of the same frequency carrier wave of the community adjacent with the community that is scheduled detected and carry out adaptability scheduling with the beam direction treating dispatched users be scheduled on carrier wave of the community that is scheduled.

In the present embodiment, base station is at non-preferential scheduling slot, to the community that is scheduled be scheduled on carrier wave treat that dispatched users is dispatched before, first obtain the schedule information of the same frequency carrier wave of the community adjacent with the community that is scheduled, for operation dispatching operation lay the first stone.

Wherein, step 201 and step 203 can see the descriptions of the step 101 in Figure 1A and step 102, and its embodiment also can respectively see the execution mode of step 101 and step 102.

The HSDPA user scheduling method of the present embodiment, in advance for the corresponding priority scheduling period is distributed in each community on each frequency carrier wave, base station judges that whether current scheduling is the priority scheduling period of the carrier wave that is scheduled of community of being scheduled, if, then carrier wave treated that dispatched users carries out normal consistency to being scheduled of the community that is scheduled, if not, then according to before the neighbor cell of the community that is scheduled at the schedule information on carrier wave and the beam direction treating dispatched users be scheduled on carrier wave of community of being scheduled of being scheduled, carrier wave treated that dispatched users carries out adaptability scheduling to being scheduled of the community that is scheduled, make to only have the priority scheduling period to be that the community of this period is by normal consistency at a scheduling slot, adaptability scheduling is carried out according to the beam direction treating dispatched users of the schedule information before respective neighbor cell and this community in other communities, and unlike prior art, adopt unique processing method to dispatch, reduce the co-channel interference between each neighbor cell on the one hand, different processing methods is selected to dispatch according to different situations on the other hand, overcome prior art and only adopt the various defects existed during any one processing method.

Channel quality instruction (the Channel Quality Indicator that step 204, base station are fed back on HS-SICH channel according to the scheduled user be scheduled on carrier wave of the community that is scheduled; Referred to as: CQI), statistics is scheduled the average CQI of the scheduled user be scheduled on carrier wave on the transmission period of the place of the HS-PDSCH of correspondence of community, the dispatching priority used when the upper once scheduling of the transmission period of HS-PDSCH corresponding to each average CQI with the scheduled user be scheduled on carrier wave of community of determining according to each average CQI to be scheduled and transport block size.

Wherein, for each user be scheduled be scheduled on carrier wave of the community that is scheduled, capital returns CQI to base station on the HS-SICH channel of dispatching distribution, so that base station based on user according to the CQI that current scheduling returns determine user upper be once scheduled time dispatching priority, and to use transport block size (Transport Block Size; Referred to as: TBS) select.

Due in the present embodiment, to same scheduled user, different scheduling slot transmission HS-PDSCH may be scheduled in, but employ different scheduling strategies and HS-PDSCH transmitted power in different scheduling slot base stations, therefore the CQI corresponding from the HS-PDSCH transmitted at different scheduling slots of the scheduled user of the present embodiment feedback has bigger difference, having reacted scheduled user has bigger difference at the channel quality of each scheduling slot.Therefore with HS-PDSCH that each scheduling slot the transmit corresponding CQI of base station to scheduled user adds up respectively by corresponding scheduling slot, calculates the current average CQI in the different scheduling slot of this dispatched users, i.e. the mean value of CQI.

Such as: for the situation that there is scheduling slot T0, T1 and T2, when the HS-PDSCH of scheduled user be transmit in scheduling slot T0 time, scheduled user returns to base station transmits corresponding CQI with HS-PDSCH, and scheduled user can return a CQI by the HS-SICH channel of dispatching distribution to base station receive the HS-PDSCH be scheduled in scheduling slot T0 after at every turn; Like this after repeatedly dispatching, base station will store the multiple CQIs of this scheduled user in scheduling slot T0, then base station according to the multiple CQI in scheduling slot T0, can obtain the average CQI in scheduling slot T0.Such as: base station by being averaged the multiple CQI in scheduling slot T0, can obtain the average CQI in scheduling slot T0.Again such as: recursive operation can be done to the CQI in scheduling slot T0 in base station, the average CQI in scheduling slot T0 is obtained.Then, base station according to the average CQI in the scheduling slot T0 obtained, obtain this user upper be once scheduled in scheduling slot T0 time dispatching priority and TBS etc.

In addition, when scheduled user is scheduled in scheduling slot T1 simultaneously, scheduled user returns corresponding CQI to base station, and after repeatedly dispatching, base station will store the multiple CQIs of this scheduled user in scheduling slot T1, then base station according to the multiple CQI in scheduling slot T1, can obtain the average CQI in scheduling slot T1.Then, base station according to the average CQI in the scheduling slot T1 obtained, obtain this user upper be once scheduled in scheduling slot T1 time dispatching priority and TBS etc.

Due on different scheduling slot, be scheduled carrier wave and the adjacent area thereof, community that be scheduled is different with the scheduling mode frequently taked, the interference that the community scheduled user be scheduled on carrier wave that makes different scheduling slot is scheduled is subject to is not identical, therefore the present embodiment does independent process by the CQI of each scheduling slot to scheduled user, and based on the average CQI after independent process obtain user upper once dispatch time the dispatching priority that uses and TBS more meet current network state, thus improve the success rate to user scheduling.
