Description

A kind of dispatching method of HSDPA resource multiplex and scheduler

Technical field

The present invention relates to the mobile communication technology field, particularly high-speed downstream bag (HSDPA) access technology, relate in particular to dispatching method and the scheduler of HSDPA resource multiplex under a kind of default training sequence deviation method of salary distribution.

Background technology

In another part patent application document (application number 201010149373.7) that the inventor proposes, propose: whole resources or part resource in the resource that HSDPA UE can multiplexing other down channels except the HS-PDSCH channel takies.Here, descending idling-resource can be considered as to a kind of special down channel.In this application file, also mention: the HSDPA scheduler is once dispatched in each subframe " n ", when this subframe is dispatched, distributes the scheduling HS-PDSCH resource of " n+d1+1 " subframe.Here, d1 means the time delay that the HSDPA scheduler of NODEB is dispatched, and this time delay means that the HSDPA scheduler of NODEB distributes to the timing difference between the subframe " n " that subframe that the HS-SCCH of scheduling UE sends and scheduler dispatch when the n subframe is dispatched.This article is also mentioned: all kinds of down channels in " n+d1+1 " sub-frame configuration can be divided into Types Below:

(1) first kind channel: the HSDPA scheduler knows that when the n subframe is dispatched each down channel that belongs to the first kind in " n+d1+1 " subframe is idle or carries the signal of which UE.In other words, be idle or carry the signal of which UE as long as scheduler is known a down channel in " n+d1+1 " subframe when the n subframe is dispatched, this down channel just belongs to first kind channel.Generally, such channel includes but not limited to: semi-persistent scheduling HS-PSCH, DLDPCH and idle downlink resource.

(2) Equations of The Second Kind channel: the HSDPA scheduler does not know to be idle or to carry the signal of which UE at each down channel that " n+d1+1 " subframe belongs to Equations of The Second Kind when the n subframe is dispatched.In other words, as long as scheduler does not know that when the n subframe is dispatched a down channel in " n+d1+1 " subframe is idle or carries the signal of which UE, this down channel just belongs to the Equations of The Second Kind channel.Such channel may include but not limited to: E-AGCH, HS-SCCH and FPACH.These may belong to the channel of Equations of The Second Kind, may in the scheduling of some subframe, belong to first kind channel, in the scheduling of other subframe, belong to the Equations of The Second Kind channel.

(3) the 3rd class channels: at the channel that community omnidirectional sends, such channel includes but not limited to: PCCPCH, SCCPCH and MICH.

This article proposes: all down channels beyond scheduling HS-PDSCH can form a variety of channel combinations, can comprise any amount of first kind channel, any amount of Equations of The Second Kind channel and any amount of the 3rd class channel in every kind of channel combination.

Can make HSDPA UE in multiplexing scheduling HS-PDSCH resource, only the channel of multiplexing first kind channel and/or the 3rd class channel composition combines the resource taken.Simultaneously, can adopt special default training sequence deviation (Midamble Shift) configuration mode and default training sequence deviation configuration mode to distribute training sequence deviation to the UE be scheduled.

Because there are distinct application scenarios in special default training sequence deviation configuration mode and default training sequence deviation configuration mode: special default training sequence deviation configuration mode is only in the situation that revise the 3GPP agreement and just can be supported, and can only be supported in the future the UE of higher 3GPP protocol version to support; And the training sequence deviation configuration mode that the UE that default training sequence deviation configuration mode is current any version will support.Simultaneously, down channel is merely able to adopt the channel code of SF=1 and SF=16 in the TD-SCDMA system, and the technical scheme that above-mentioned application documents propose does not take into full account this constraints.Therefore, the technical scheme of above-mentioned application documents proposition still requires further improvement.

1 embodiment mono-

At present, the training sequence deviation number K of community is K=8 by default configuration.Therefore, at first for this configuration, introduce HSDPA resource multiplex mode of the present invention and this resource multiplex mode dispatching device and dispatching method.

At the training sequence deviation number K of community, by default configuration, be K=8 and adopt in default training sequence deviation configuration mode Shi， community the mapping relations between OVSF channel code and training sequence deviation as shown in Figure 1.In Fig. 1, m ⁽ⁱ⁾, i=1,2 ... .., 8 mean i training sequence deviation;

Due in the TD-SCDMA system, the descending channel code that is merely able to adopt SF=1 and SF=16, therefore, the HS-PDSCH that can distribute to UE when K=8 has following feature:

(1) by the channel code of SF=1

As HS-PDSCH, distribute to UE, correspondingly, the training sequence deviation of distributing to UE is: m ⁽¹⁾

(2) will

Etc. one or more UE that distribute in channel code, as the HS-PDSCH of UE, correspondingly, the corresponding training sequence deviation of the channel code of distributing to UE is distributed to UE.

(3) each training sequence deviation m ⁽¹⁾, m ⁽²⁾..., m ⁽⁸⁾The channel code of corresponding two SF=16, as shown in rightmost row in Fig. 1.In two channel code by the same training sequence deviation of correspondence, distribute to a UE for one, the one other channel code just can not be distributed to other UE, or this channel code is distributed to same UE, or throws aside.Otherwise, there will be two UE to use different channel code but to use identical training sequence deviation, cause the downstream signal of two UE to obscure together, can't distinguish.Such as, m ⁽²⁾Simultaneously corresponding two channel code

With

When will be wherein 1 distribute to UE1, another or distribute to UE1 or throw aside.

When adopting above-mentioned default training sequence deviation configuration mode, any one descending time slot on any one carrier wave, if realize the resource multiplex between HSDPA UE at this time slot, the resource multiplex flow process that the embodiment of the present invention one proposes as shown in Figure 2, comprises the steps:

With training sequence deviation m ⁽¹⁾Distribute to a UE.

(2) step 202: by remaining 7 the training sequence deviation " m of this time slot ⁽²⁾..., m ⁽⁸⁾" and the channel code of 14 SF=16s corresponding with these training sequence deviation

Distribute to other UE except a UE.

In any one descending time slot be scheduled on any one carrier wave be scheduled in above-mentioned flow process ，Zai community, between each HSDPA UE, distribute the channel code of 1 SF=1

Channel code with 14 SF=16

Under above-mentioned resource multiplex mode, the resource sum that can distribute to each UE in this time slot of this carrier wave is: the channel code of the channel code of 1 SF=1 and 14 SF=16.The channel code of 1 SF=1 is equivalent to the channel code resources of 16 SF=16, and therefore, the assignable channel code of this time slot is under this mode: the channel code of 30 SF=16.

If do not adopt above-mentioned resource multiplex mode, can also adopt the following resource multiplex mode that any substitutes at each time slot.Following two kinds of alternative resource multiplex modes are resource multiplex modes that currently available technology adopts.Compared with prior art, under the resource multiplex mode of above-mentioned each time slot, spectrum efficiency has improved 14/16=7/8 doubly than prior art.

(1) by the channel code of 1 SF=1 of this time slot

With training sequence deviation m ⁽¹⁾Distribute to 1 UE, other 7 training sequence deviation " m ⁽²⁾..., m ⁽⁸⁾" and the channel code of 14 SF=16s corresponding with these training sequence deviation

Throw aside.Under this mode, on being scheduled carrier wave, this in this time slot, distributes the channel code resources of 1 SF=1 between each HSDPA UE.Under this mode, the resource sum that can distribute to each UE is the corresponding resource of channel code of 16 SF=16.And, under this mode, only support to dispatch a UE at this time slot.

(2) by 8 training sequence deviation " m of this time slot ⁽¹⁾, m ⁽²⁾..., m ⁽⁸⁾" and the channel code of 16 SF=16s corresponding with these training sequence deviation

Distribute to UE.Due to the channel code with 1 SF=1

Corresponding training sequence deviation m ⁽¹⁾Be used to distributing channel mode So the channel code of SF=1 can't be used.Under this mode, on being scheduled carrier wave, this in this time slot, distributes the channel code of 16 SF=16 between each HSDPA UE

Under this mode, the resource sum of distributing to each UE is the channel code resources of 16 SF=16.

Under the resource multiplex mode of each above-mentioned time slot, the carrier wave that is scheduled in the time of should forming K=8 in the following manner is at the scheduling HS-PDSCH of each subframe " n " resource pool.

(1) the channel combination that the first kind channel that appointment HSDPA UE can be multiplexing and/or the 3rd class channel form.

(2) at each subframe " n ", the HS-PDSCH resource pool of this subframe scheduling various channels in the channel combination of scheduling HS-PDSCH resource and described appointment in " n+d1+1 " subframe form in the shared resource of " n+d1+1 " subframe.

(3) each descending time slot described scheduling HS-PDSCH resource pool comprised is divided into three classes:

● first kind time slot: if in a time slot training sequence deviation m ⁽¹⁾Leave unused, this time slot belongs to first kind time slot." training sequence deviation in a time slot (such as: m ⁽¹⁾) leave unused " refer to: this training sequence deviation in this time slot (such as: m ⁽¹⁾) corresponding channel code belongs to scheduling HS-PDSCH resource and idle downlink resource, is not assigned to other down channels; Perhaps, although distribute to some down channels, this down channel " n+d1+1 " subframe shared with this training sequence deviation (such as m ⁽¹⁾) corresponding channel code leaves unused.If the channel code of an interior SF=1 of time slot or the channel code of all SF=16 all belong to scheduling HS-PDSCH resource or idle downlink resource, this time slot must be first kind time slot.

The Equations of The Second Kind time slot: if all training sequence deviation are all left unused in a time slot, this time slot belongs to the Equations of The Second Kind time slot.If the channel code of an interior SF=1 of time slot or the channel code of all SF=16 all belong to scheduling HS-PDSCH resource or idle downlink resource, this time slot necessarily belongs to the Equations of The Second Kind time slot.The time slot that belongs to the Equations of The Second Kind time slot necessarily belongs to first kind time slot.

The 3rd class time slot: any one belongs in the time slot of the 3rd class, only has the part training sequence deviation to leave unused.If only have the channel code of part SF=16 to belong to scheduling HS-PDSCH resource or the downlink resource of free time or the idle shared resource of down channel in a time slot, this time slot necessarily belongs to the 3rd class time slot.In each time slot that scheduling HS-PDSCH resource pool comprises, all time slots that do not belong to the Equations of The Second Kind time slot all belong to the 3rd class time slot.

(4) above-mentioned scheduling HS-PDSCH resource pool can resolve into following two sub-resource pools:

First child resource pond: this resource pool consists of each time slot that belongs to first kind time slot, and this resource pool comprises the channel code of 1 SF=1 in each time slot With training sequence deviation m ⁽¹⁾.This resource pool only supports to distribute the channel code of SF=1 to UE

Second sub-resource pool: this resource pool consists of Equations of The Second Kind time slot and the 3rd class time slot.Within belonging to each time slot of Equations of The Second Kind time slot, this resource pool is by the channel code of 14 SF=16

With 7 training sequence deviation m ⁽²⁾..., m ⁽⁸⁾Form.In each time slot that belongs to the 3rd class time slot, this resource pool is by non-m ⁽¹⁾The channel code of each idle corresponding SF=16 of training sequence deviation form, also namely in the channel combination of scheduling HS-PDSCH resource, idle downlink resource and appointment the slack resources in the resource of various channel occupancies form.

Under above-mentioned resource multiplex mode, scheduling HS-PDSCH resource pool can be divided into two sub-resource pools.Scheduler and dispatching method that the present invention proposes are dispatched based on these two sub-resource pools.

Below illustrate the formation in above-mentioned scheduling HS-PSCH resource pool and child resource pond.

The Typical Disposition of 3:3 is adopted in community, and TS4-TS6 is descending time slot.In each subframe, scheduling HS-PDSCH resource pool consists of the resource of the various channel occupancies that the channel combination of dispatching HS-PDSCH resource and appointment comprises.The whole resources that comprise TS4 and TS5 in each subframe scheduling HS-PDSCH resource.In the channel combination of appointment, include only idle downlink resource.In each subframe, idle downlink resource comprises: 8 channel code of TS6 Other channel code of TS6 are for distributing following down channel.

(1) TS6

For allocation of downlink dedicated physical channels (DL DPCH);

(2) TS6

For distributing High-Speed Shared Control Channel (HS-SCCH);

(3) TS6

For distributing, strengthen dedicated channel hybrid automatic repeat request indication channel (E-HICH);

(4) TS6

For distributing, strengthen dedicated channel absolute grant channel (E-AGCH).

Due to TS6's

For distributing above-mentioned down channel, therefore, the training sequence deviation m corresponding with these channel code ⁽¹⁾..., m ⁽⁴⁾Do not leave unused.At TS6, with other 8 channel code that belong to idle downlink resource

4 corresponding training sequence deviation m ⁽⁵⁾..., m ⁽⁸⁾Leave unused.

In sum, in each subframe, scheduling HS-PDSCH resource pool is by whole resources of TS4 and TS5 and 8 channel code of TS6

Form.With table 1, mean this scheduling HS-PDSCH resource pool.In table 1, every row represent 1 time slot; Each row of every row represents the channel code of 2 SF=16.

In above-mentioned scheduling HS-PDSCH resource pool, TS4 and TS5 not only belong to first kind time slot but also belong to the Equations of The Second Kind time slot; TS6 belongs to the 3rd class time slot.

Table 1: scheduling HS-PDSCH resource pool

According to the constituted mode of above-mentioned HSDPA resource multiplex mode and two sub-resource pools, two sub-resource pools can be resolved in the pond of scheduling resource shown in table 1, as shown in table 2 and table 3.Wherein, table 2 illustrates first child resource pond and consists of first kind time slot TS4 and TS5, and this child resource pond of each time slot in TS4 and TS5 is by the channel code of 1 SF=1

With training sequence deviation m ⁽¹⁾Form.Second sub-resource pool consists of TS4, TS5 and TS6.Table 3 is illustrated in second resource pool, and in each time slot in Equations of The Second Kind time slot TS4 and TS5, this child resource pond is by the channel code of 14 SF=16

With 7 training sequence deviation " m ⁽²⁾..., m ⁽⁸⁾Form; In the 3rd class time slot TS6,8 channel code of this child resource pond TS6 in above-mentioned scheduling HS-PDSCH resource pool

With 4 the training sequence deviation " ms corresponding with these channel code ⁽⁵⁾..., m ⁽⁸⁾Form.

But, if TS6 Or m ⁽¹⁾Be not assigned to DL DPCH, in this resource pool, TS4, TS5 and TS6 belong to first kind time slot; TS4 and TS5 belong to the Equations of The Second Kind time slot; TS6 belongs to the 3rd class time slot.First child resource pond consists of TS4, TS5 and TS6, as shown in table 4.Correspondingly, second sub-resource pool is as shown in table 5.

Table 2: first child resource pond

Table 3: second sub-resource pool

Table 4: first child resource pond

Table 5: second sub-resource pool

Be scheduled each UE on carrier wave with the resource in multiplexing first child resource pond of time division way, with the resource in time-division and code minute multiplexing second the sub-resource pool of mode.

When distributing the resource in first child resource pond for a UE, can only be by several time slot allocation to UE.Because each time slot includes only a channel code

Therefore, in first child resource pond, during to the UE Resources allocation, only need to determine that the number of time slot that distribute to UE gets final product.

On the UE be scheduled on each child resource pond and another child resource pond, take between the UE of same asset and form the resource multiplex relation.Such as: TS4 in first child resource pond has been distributed to UE1, dispatched now UE2, wish is distributed to UE2 by 14 channel code of TS4 in second sub-resource pool.Between UE1 and UE2, form the resource multiplex relation.

According to the difference of UE to the downstream signal detectability, can adopt different processing modes:

When UE is very strong to the detectability of downstream signal, even other UE and its multiplexing identical resource are arranged, when UE also can correctly detect the downstream signal of oneself, the wireless channel needed only between two UE was not identical, and two UE just can multiplexing identical resource.Such as: the wireless channel of UE1 and UE2 is different, directly 14 code channels of TS4 is distributed to UE2 just passable.NODEB carries out channel estimating according to the reception signal of the up channel of each UE, obtains the channel estimating of each UE on each antenna of NODEB side.According to the channel estimating of each UE, can obtain the down beam shaping vector of UE.Judge between two UE whether identical method includes but not limited to following two kinds to wireless channel:

(1) if the channel estimating of two UE on each antenna incomplete same think: the wireless channel between two UE is not identical.

(2) if the down beam shaping vector of two UE is not identical, think: the wireless channel between two UE is not identical.

When UE very weak to the detectability of downstream signal, if other UE and its multiplexing identical resource are arranged, when UE is difficult to by the downstream signal of the correct detection of self-ability oneself, NODEB is when realizing resource multiplex, and the correlation between the wireless channel of two UE of the multiplexing same asset of needs assurance is very weak.When the wireless channel correlation between two UE is very strong, just do not allow the multiplexing identical resource of these two UE.Such as, when the wireless channel correlation of the wireless channel of UE2 and UE1 is strong, just the channel code resources of 14 SF=16 of TS4 is not distributed to UE2, the resource of other time slots can be distributed to UE2.When a little less than the wireless channel correlation of the wireless channel of UE2 and UE1, just the resource of TS4 can be distributed to UE2.Judge that the strong and weak method of wireless channel correlation between two UE is on the books at another part patent application document (application number 201010149373.7) of the inventor, this part content is not the emphasis that the present invention is concerned about, repeats no more here.

When the above has introduced K=8, adopt under default the training sequence deviation method of salary distribution and resource multiplex situation, scheduling HS-PDSCH resource pool can resolve into two sub-resource pools under best resource multiplex mode.Can at these two sub-resource pools, dispatch respectively.Make the resource of each HSDPA UE in can multiplexing these two sub-resource pools.

Below provide the HSDPA scheduling flow of the embodiment of the present invention one, as shown in Figure 3, comprise the steps:

Step 301: determine the combination of the HS-PDSCH channel type in addition that HSDPA UE can be multiplexing.This channel type combination can only consist of first kind channel and/or the 3rd class channel.The channel type that UE can be multiplexing is only enumerated in described channel type combination, but does not relate to concrete multiplexing which channel.

Step 302: determine whether to consider the multiplexing ability of UE support resource in resource multiplex.

If do not consider the ability that the UE support resource is multiplexing, just equal acquiescence: even the downlink resource of a UE is multiplexing by other UE, UE has enough abilities correctly to detect downstream signal.In this case, when two UE carry out resource multiplex, as long as the wireless channel of two UE is not identical.

If consider the multiplexing ability of UE support resource, just equal to think: UE does not have enough abilities correctly to detect downstream signal when the downlink resource of a UE is multiplexing by other UE.In this case, when two UE carry out resource multiplex, just need to investigate correlation between the wireless channel of this two UE whether enough a little less than.When the correlation between the wireless channel of two UE is enough weak, these two multiplexing identical resources of UE ability; Otherwise, can not multiplexing identical resource between these two UE.

The scheduling of step 303:HSDPA scheduler start-up period.In any one subframe " n " subsequently, the HSDPA scheduler carries out a HSDPA scheduling.

In any subframe " n ", the scheduling step of HSDPA scheduler as shown in Figure 4, comprises the steps:

Step 303-1: the dispatching priority of determining each HSDPA UE of " n " subframe.According to dispatching priority order from high to low, all UE are queued up.Come the top UE of formation and have the highest dispatching priority, come the rearmost UE of formation and have minimum dispatching priority.

The method that the scheduler of NODEB calculates each HSUPA UE dispatching priority is a lot, such as: polling method, maximum C/I (carrier/interface ratio) method and PF (equitable proportion) method etc.The detailed introduction of these methods refers to existing document.Because the method for the dispatching priority that calculates each UE is not content of the present invention, repeat no more here.

Step 303-2: determine the HS-SCCH that can use in current subframe.In current subframe, all HS-SCCH that configure on the carrier wave be scheduled are available HS-SCCH.

Step 303-3: determine scheduling HS-PDSCH resource pool.

Scheduling HS-PDSCH resource in n subframe HSDPA scheduler schedules " n+d1+1 " subframe.Step 303-3 specifically comprises following sub-step:

Step 303-3-1: at first determine the resource at n+d1+1 subframe scheduling HS-PDSCH.

The HS-PDSCH resource pool that RNC configures to UE consists of to the semi-static HS-PDSCH of each UE and scheduling HS-PDSCH resource configuration." n+d1+1 " subframe scheduling HS-PDSCH resource equals to configure from RNC the resource that forecloses and obtain to the resource the HS-PDSCH resource pool of UE, the semi-static HS-PDSCH of each UE in " n+d1+1 " subframe taken.

Step 303-3-2: because this scheduler can be realized the shared resource of various channels that multiplexing any one channel combination in all channel combinations that first kind channel and/or the 3rd class channel form of HSUPA UE comprises, therefore, in the present invention, " n+d1+1 " subframe scheduling HS-PDSCH resource pool comprises that all kinds of channels that in the scheduling HS-PDSCH resource of " n+d1+1 " subframe and step 301, determined channel combination comprises are in the shared resource of " n+d1+1 " subframe.

If in certain class channel that this channel combination comprises, some channels leave unused in the resource that " n+d1+1 " subframe takies, the training sequence deviation corresponding with this resource left unused.Otherwise this training sequence deviation is not left unused.

According to above-mentioned processing, the channel group of determining in step 301 is share in the scheduling HS-PDSCH resource pool of determining " n+d1+1 " subframe that each subframe " n " is used.But in different subframes, NODEB may be in different application scenarioss, and the occupation condition of different application scene channel can be different, and the resource of therefore dispatching in the HS-PDSCH resource pool also can be different.A kind of preferably processing mode is to pre-define plurality of application scenes, and be every kind of channel combination that scene setting is corresponding.When each subframe " n " formed " n+d1+1 " subframe scheduling HS-PDSCH resource pool, the scene that judgement " n+d1+1 " subframe meets, then adopted the channel combination of determining under this scene." n+d1+1 " subframe scheduling HS-PDSCH resource pool comprises that all kinds of channels that the scheduling HS-PDSCH resource of " n+d1+1 " subframe and the combination of determined channel comprise are in the shared resource of " n+d1+1 " subframe.

If the some channels in certain class channel that determined channel combination comprises leave unused in the shared resource of " n+d1+1 " subframe, the training sequence deviation corresponding with this resource left unused.Otherwise this training sequence deviation is not left unused.

Step 303-4: the classification of each time slot in judgement scheduling HS-PDSCH resource pool, resolve into two sub-resource pools according to the classification of time slot by above-mentioned scheduling HS-PDSCH resource pool.

Each descending time slot that above-mentioned scheduling HS-PDSCH resource pool is comprised is divided into three classes:

First kind time slot: any one belongs to the interior training sequence deviation m of time slot of the first kind ⁽¹⁾Leave unused.

The Equations of The Second Kind time slot: any one belongs to all training sequence deviation in the time slot of Equations of The Second Kind and all leaves unused.

The 3rd class time slot: any one belongs in the time slot of the 3rd class only has the part training sequence deviation to leave unused.In other words, all in scheduling HS-PDSCH resource pool is not that the time slot of Equations of The Second Kind time slot all belongs to the 3rd class time slot.

According to the multiplexing best mode of each time interval resource, above-mentioned scheduling HS-PDSCH resource pool is resolved into to following two sub-resource pools:

First child resource pond: this resource pool consists of each time slot that belongs to first kind time slot, and this resource pool includes only the channel code of 1 SF=1 in each time slot

This resource pool only supports to distribute the channel code of SF=1 to UE.

Form.In each time slot that belongs to the 3rd class time slot, the non-m that this resource pool is comprised in this time slot by above-mentioned scheduling HS-PDSCH resource pool ⁽¹⁾The channel code of each idle corresponding SF=16 of training sequence deviation form.

Preferably, each descending time slot that may comprise at scheduling HS-PDSCH resource pool, by m ⁽¹⁾Corresponding channel code is distributed to the down channel beyond scheduling HS-PDSCH.

Step 303-5: start to dispatch one by one UE according to queue sequence from the highest UE of priority.

To the scheduling flow of a UE as shown in Figure 5, comprise the steps:

Step 501: when a UE of scheduling, distribute to UE from selecting a HS-SCCH all available HS-SCCH.

Step 502: distribute to UE as HS-PDSCH from selecting suitable resource two sub-resource pools.If the HS-PDSCH resource of selecting can't be carried the minimum data piece of UE, just finish the scheduling to current UE, start next UE in the dispatching priority formation.To the scheduling of next UE from above-mentioned steps 501.

This step is determined the HS-PDSCH that distributes to UE according to following sub-step:

Step 502-1: the number that calculates the needed channel code of UE that is scheduled.

According to the CQI of the up-to-date HS-PDSCH of the UE that is scheduled, NODEB can know the HS-DSCH data volume A that the channel code of 1 SF=16 can be carried.According to the HS-DSCH data total amount B of this UE, NODEB calculates the number be used to the channel code of the needed SF=16 of all HS-DSCH data that carries this UE

Step 502-2: when a UE of scheduling, at first need the time slot of determining that in first child resource pond, this UE can use.Then, in this child resource pond, select suitable resource as alternative HS-PDSCH.

To any one time slot in first child resource pond, if, while in this time slot, having other down channels beyond scheduling HS-PDSCH resource and descending idling-resource, need to determine whether this time slot can be used for this UE according to following method:

If this time slot exists first kind channel and these channels not to leave unused in " n+d1+1 " subframe, determine the signal of which UE of carrying on each down channel.

In the time according to step 302 is definite, need in resource multiplex, not investigating the ability of UE, whether the wireless channel of the UE carried on the wireless channel of the UE that investigation is scheduled and above-mentioned each down channel is identical.If identical, in this first child resource pond, this time slot can not be used by UE; If different, in this first child resource pond, this time slot can be used by UE.

When according to step 302, determining while need in resource multiplex, investigate the ability of UE, the correlation between the wireless channel of the UE carried on the wireless channel of the UE that investigation is scheduled and above-mentioned each down channel whether a little less than.If the correlation between the wireless channel of the UE carried on UE and one of them down channel not a little less than, just think that this time slot can not be used for UE.

In addition, if when the UE be scheduled was exactly the UE carried on some first kind down channels, this time slot can not be used for UE.

If before this UE, when this time slot has the UE successfully dispatched, when according to step 302, determining while need in resource multiplex, not investigate the ability of UE, whether identically investigate at the wireless channel of the wireless channel of each UE successfully dispatched of this time slot and this UE.If the wireless channel of the UE that one of them is successfully dispatched is identical with the wireless channel of this UE, in this first child resource pond, this time slot can not be used for UE.Here, describedly by the UE that successfully dispatched, referred to: if there is a UE successfully to be dispatched, when the HS-PDSCH that distributes to this UE comprised some descending time slots, this UE was exactly the UE that in this descending time slot, quilt is successfully dispatched.

If before this UE when this time slot has the UE successfully dispatched, when according to step 302, determining while need in resource multiplex, investigate the ability of UE, investigate the correlation of the wireless channel of the wireless channel of each UE successfully dispatched and the current UE of being scheduled.If the correlation between the wireless channel of the wireless channel of UE and the UE that one of them is successfully dispatched not a little less than, just think that this time slot can not be used for UE.

Through above-mentioned processing, this time slot can not be used for UE if can not determine, this time slot can be used for UE.

According to the method described above, can determine each time slot that in first child resource pond, this UE can use, then, calculate the needed number of time slot of UE according to the channel code number X of the needed SF=16 of this UE

Here,

Expression on x, rounding, that is: selects to be greater than the smallest positive integral of x.

The HS-PDSCH number of time slot that each UE can support is restricted.Some UE can support the HS-PDSCH of U=2 time slot; Some UE can support the HS-PDSCH of U=5 time slot.Therefore, the number of time slot of selecting in available time slot in first child resource pond can not surpass the maximum number of time slot of HS-PDSCH that UE can support.The maximum number of time slot of the HS-PDSCH that U can support for this UE.

Therefore, in the time slot that need to can use this UE, select Y time slot in first child resource pond.Y=min{T, Z, U}, wherein, the time slot sum that Z can use for this UE in first resource pool; Min{T, Z, U} mean to get the minimum value in T, Z and U.Alternative HS-PDSCH using the resource of Y time slot in first child resource pond as UE.

If in the first child resource pond not this UE can use time slot the time, go to the execution step 502-3.

Step 502-3: determine the resource that in second sub-resource pool, this UE can use.Then, in this child resource pond, select suitable resource as alternative HS-PDSCH.

Because the UE that uses same asset in the UE in second sub-resource pool and first child resource pond forms the resource multiplex relation, if when before this UE, in first resource pool, the UE successfully dispatched being arranged, whether the resource of need investigating in each shared descending time slot of the UE that successfully dispatched can be used for the current UE be scheduled.

In the time according to step 302 is definite, need in resource multiplex, not investigating the ability of UE, whether the wireless channel of investigating the wireless channel of the UE be scheduled and the UE that quilt is successfully dispatched in first resource pool is identical.If identical, the resource in each descending time slot that the UE that this quilt is successfully dispatched in second sub-resource pool takies can not be used for UE.If not identical, the resource in each time slot that the UE that this quilt is successfully dispatched in second sub-resource pool takies can be used for UE.

When according to step 302, determining while need in resource multiplex, investigate the ability of UE, investigate between the wireless channel of the wireless channel of the UE be scheduled and the UE that quilt is successfully dispatched in first child resource pond correlation whether a little less than.If the wireless channel correlation between these two UE not a little less than, just think that the resource in each descending time slot that this quilt is successfully dispatched in second sub-resource pool UE takies can not be used for UE.If a little less than the wireless channel correlation between these two UE, just think that the resource in each descending time slot that this quilt is successfully dispatched in second sub-resource pool UE takies can be used for UE.

Such as the wireless channel of: the wireless channel of the current UE be scheduled and a UE who is successfully dispatched is identical or correlation is very strong, from being somebody's turn to do each descending time slot that UE was used of successfully being dispatched in second sub-resource pool, remove.For another example: before the current UE be scheduled, two UE that successfully dispatched are arranged in first resource pool.First UE only takies TS3, and second UE takies TS4 and TS5.If the wireless channel of the UE be scheduled current when only or correlation identical with the wireless channel of first UE is very strong, removes TS3 in second sub-resource pool, all resources in TS3 all can not be used for the current UE be scheduled; In second sub-resource pool, the resource of TS4 and TS5 can be that the current UE be scheduled is used.If the wireless channel of the UE be scheduled current when just or correlation identical with the wireless channel of second UE is very strong, all removes TS4 and TS5 in second sub-resource pool, all resources in TS4 and TS5 all can not be used for the current UE be scheduled; In second sub-resource pool, the interior resource of TS3 can be that the UE be scheduled is used.

After determining the resource that in second resource pool, this UE can use according to the method described above, channel code number according to the needed SF=16 of this UE, in second resource pool this UE can with resource in to select a rectangle resource that is no more than the UE ability, this rectangle resource be minimum rectangle during the channel code number of the SF=16 that comprises is not less than all rectangles of X.Using this rectangle as alternative HS-PDSCH.So-called rectangle resource, refer to that this resource occupies identical and continuous channel code at each time slot taken.

If when the channel code number that the maximum rectangle resource of the UE ability that is no more than of selecting in the available resources to this UE in second resource pool comprises all is less than X, directly should maximum rectangle resource as alternative HS-PDSCH.

If this second resource pool do not comprise the channel code that any this UE can use, perform step 502-4.

Step 502-4: the HS-PDSCH that determines UE.

When through above-mentioned processing, having to an alternative HS-PDSCH, this HS-PDSCH is distributed to UE.

When through above-mentioned processing, obtaining two alternative HS-PDSCH, if when these two alternative HS-PDSCH can't carry the total data amount of UE, select the maximum HS-PDSCH of number of the channel code of the SF=16 comprised to distribute to UE.

When through above-mentioned processing, obtaining two alternative HS-PDSCH, if when these two alternative HS-PDSCH can carry the total data amount of UE, select the HS-PDSCH of minimum number of the channel code of the SF=16 comprised to distribute to UE.

When through above-mentioned processing, obtaining two alternative HS-PDSCH, if, while only having an alternative HS-PDSCH can carry the total data amount of UE, select this HS-PDSCH to distribute to UE.

Scheduling to this UE in following situation is failed:

When through above-mentioned processing, not obtaining any alternative HS-PDSCH, the scheduling failure to this UE, directly start to dispatch next UE.

If when distributing to the HS-PDSCH of UE and can not carry the minimum data piece of UE, to the scheduling failure of this UE.Start to dispatch a next UE.

To the scheduling of next UE from above-mentioned steps 501.

Step 503: will distribute to this UE with the HS-SICH of the HS-SCCH pairing of distributing to UE, as the scheduling HS-SICH of this UE.

Step 504: distribute training sequence deviation to UE.

As the HS-PDSCH that distributes this UE during from first child resource pond, will

And m ⁽¹⁾Distribute to UE; As the HS-PDSCH that distributes to this UE, during from second sub-resource pool, the corresponding training sequence deviation of each channel code that this HS-PDSCH comprises is distributed to UE.

Step 505: will distribute to the HS-SCCH of this UE from removing available HS-SCCH, and upgrade two sub-resource pools.

After according to above-mentioned steps, being successfully UE distribution HS-SCCH, HS-PDSCH, HS-SICH and the training sequence deviation be scheduled, show: this UE is successfully dispatched.

Upgrade as follows two sub-resource pools, the HS-PDSCH resource of distributing to UE is removed in corresponding child resource pond: as the HS-PDSCH that distributes to UE during from first child resource pond, each time slot that the HS-PDSCH that distributes to this UE is taken is from removing the time slot that first child resource pond comprises; As the HS-PDSCH that distributes to UE during from second sub-resource pool, each channel code that the HS-PDSCH that distributes to this UE is taken is from removing in the channel code that second sub-resource pool comprises.

After completing above-mentioned processing, if do not have available HS-SCCH just to perform step 506.If after completing above-mentioned processing, first child resource pond does not comprise when any time slot and second sub-resource pool do not comprise any channel code, just performs step 506.

After completing above-mentioned processing, if available HS-SCCH is arranged, and have at least in a sub-resource pool while comprising available resource in two sub-resource pools, just start next UE in the dispatching priority formation.To the scheduling of next UE from above-mentioned steps 501.To the scheduling of next UE two sub-resource pools based on above-mentioned renewal.

Step 506: each UE to successfully being dispatched sends to physical layer by distributing to HS-SCCH, the HS-PDSCH of this UE and the information of HS-SICH.

To each UE be scheduled, at first physical layer sends to UE at the HS-SCCH that the n+d1 subframe will be distributed to this UE; Then in the n+d1+1 subframe, HS-PDSCH is sent to UE; Finally, in the n+d1+3 subframe, receive UE and by HS-SICH, send to the ACK/NACK information of HS-DSCH data block of NODEB and the CQI information of HS-PDSCH.

Embodiment bis-

When the training sequence deviation number K of community can get any possible values, and while adopting default training sequence deviation configuration mode, the mapping relations in each K Zhi Xia community between OVSF channel code and training sequence deviation are defined with the form that is similar to Fig. 1 in embodiment mono-in the 3GPP agreement.At present, K can be in 2,4,6,8,10,12,14 and 16 arbitrarily during value, and still, the present embodiment is not limited to K value in above-mentioned value.If the span of K is expanded later, the present embodiment can directly apply to the K value of expansion.Mapping relations during K=16 between OVSF channel code and training sequence deviation as shown in Figure 2.In Fig. 2, m ⁽ⁱ⁾, i=1,2 ... .., 16 mean i training sequence deviation;

Mean that spreading factor is j channel code in the channel code of SF, SF=1,2,4,8,16, j=1,2 ..., SF.

No matter why K is worth, under each different K value, with the channel code of SF=1 Corresponding training sequence deviation is all m ⁽¹⁾.Just under different K values, by m ⁽¹⁾After removing, remaining training sequence deviation number is K-1, and this remaining training sequence deviation number is difference along with the difference of K value.And in remaining training sequence deviation, the channel code of SF=16 corresponding to each training sequence deviation is under different K and not all identical.

But no matter why K is worth, and at the TD-SCDMA system descending, all is merely able to adopt the channel code of SF=1 and SF=16.Therefore, no matter why K is worth, and the HS-PDSCH that can distribute to UE has following characteristic feature:

(1) by the channel code of SF=1

(2) will

Etc. one or more UE that distribute in channel code, as the HS-PDSCH of UE, correspondingly, the training sequence deviation that the channel code of distributing to UE is corresponding is distributed to UE.

(3) at m ⁽¹⁾, m ⁽²⁾..., m ^(K)In the channel code of the corresponding one or more SF=16 of each training sequence deviation.As shown in rightmost row in Fig. 2, the channel code of corresponding 1 SF=16 of each training sequence deviation when K=16.But, in Fig. 1, the channel code of corresponding 2 SF=16 of each training sequence deviation during K=8.When K was worth for other, the channel code number of the SF=16 that each training sequence deviation is corresponding may be also other values.

When adopting default training sequence deviation configuration mode, no matter why K is worth, and for any one descending time slot, if realize the resource multiplex between HSDPA UE at this time slot, this resource multiplex mode is as follows:

(1) by the channel code of 1 SF=1 of this time slot

With training sequence deviation m ⁽¹⁾Distribute to a UE.

(2) by the remaining K-1 of this a time slot training sequence deviation m ⁽²⁾..., m ^(K)With the channel code of all SF=16s corresponding with these training sequence deviation, distribute to other UE except a UE.

In any one time slot be scheduled on any one carrier wave be scheduled in above-mentioned resource multiplex mode ，Zai community, between each HSDPA UE, distribute the channel code of 1 SF=1

With with m ⁽²⁾..., m ^(K)The channel code of corresponding each SF=16.Under above-mentioned resource multiplex mode, the resource sum that can distribute to each UE on any one carrier wave be scheduled in any one time slot be scheduled is: the channel code of 1 SF=1 and and m ⁽²⁾..., m ^(K)The channel code of corresponding each SF=16.Under this mode, the channel code number of the SF=16 of the equivalence that each time slot can distribute is greater than 16.

Above-mentioned resource multiplex mode is resource multiplex mode best in the TD-SCDMA system.If do not adopt above-mentioned resource multiplex mode, can only adopt following two kinds of resource multiplex modes at each time slot.But following two kinds of resource multiplex modes resource that above-mentioned best resource mode can distribute that all is far from is large.

(1) by the channel code of 1 SF=1 of this time slot

With training sequence deviation m ⁽¹⁾Distribute to a UE, other K-1 training sequence deviation " m ⁽²⁾..., m ^(K)" and the channel code of each SF=16 corresponding with these training sequence deviation throw aside.Under this mode, on being scheduled carrier wave, this in this time slot, distributes the channel code resources of 1 SF=1 between each HSDPAUE.Under this mode, the resource sum of distributing to each UE is the corresponding resource of channel code of 16 SF=16.And under this mode, each time slot only supports to dispatch 1 UE.

(2) by K training sequence deviation " m of this time slot ⁽¹⁾, m ⁽²⁾..., m ^(K)" and the channel code of 16 SF=16s corresponding with these training sequence deviation

Distribute to UE.Due to the channel code with 1 SF=1

Corresponding training sequence deviation m ⁽¹⁾The channel code of SF=1 is used to distribute the channel code of corresponding SF=16, so can't be used.Under this mode, between each HSDPA UE on this is scheduled carrier wave, distribute the channel code of 16 SF=16

Under the best resource multiplex mode of each time slot, under different K values, forming the carrier wave that is scheduled is identical in the method for the scheduling HS-PSCH of each subframe " n " resource pool.

(2) at each subframe " n ", the HS-PDSCH resource pool of this subframe scheduling consists of in the shared resource of " n+d1+1 " subframe the various channels that the combination of the channel of this subframe scheduling HS-PDSCH resource and appointment comprises.If in a certain class channel that the combination of the channel of appointment comprises, some channels leave unused in the shared resource of " n+d1+1 " subframe, the corresponding training sequence deviation of the shared resource of this channel is left unused; Otherwise the corresponding training sequence deviation of the shared resource of this channel is not just left unused.

(3) each descending time slot above-mentioned scheduling HS-PDSCH resource pool comprised is divided into three classes:

First kind time slot: any one belongs to the interior training sequence deviation m of time slot of the first kind ⁽¹⁾Leave unused." training sequence deviation in a time slot (such as: m ⁽¹⁾) leave unused " refer to: this training sequence deviation in this time slot (such as: m ⁽¹⁾) corresponding channel code belongs to scheduling HS-PDSCH resource and idle downlink resource, is not assigned to other down channels; Perhaps, although distribute to some down channels, this down channel " n+d1+1 " subframe shared with this training sequence deviation (such as m ⁽¹⁾) corresponding channel code leaves unused.If when the channel code of the SF=1 in time slot or the channel code of all SF=16 all belonged to the slack resources in the shared resource of scheduling HS-PDSCH resource or idle downlink resource or down channel, this time slot must be first kind time slot.

The Equations of The Second Kind time slot: any one belongs to all training sequence deviation in the time slot of Equations of The Second Kind and all leaves unused.The time slot that belongs to Equations of The Second Kind necessarily belongs to first kind time slot.If when the channel code of the SF=1 in time slot or the channel code of all SF=16 all belonged to the slack resources in the shared resource of scheduling HS-PDSCH resource or idle downlink resource or down channel, this time slot must be the Equations of The Second Kind time slot.

The 3rd class time slot: any one belongs in the time slot of the 3rd class only has the part training sequence deviation to leave unused.All in scheduling HS-PDSCH resource pool is not that the time slot of Equations of The Second Kind time slot all belongs to the 3rd class time slot.

(4) under above-mentioned resource multiplex mode, scheduling HS-PDSCH resource pool can resolve into two sub-resource pools:

First child resource pond: this resource pool consists of each time slot that belongs to first kind time slot, and this resource pool comprises the channel code of 1 SF=1 in each time slot

With training sequence deviation m ⁽¹⁾.This resource pool only supports to distribute the channel code of SF=1 to UE.

Second sub-resource pool: this resource pool consists of Equations of The Second Kind time slot and the 3rd class time slot.Within belonging to each time slot of Equations of The Second Kind time slot, this resource pool by with m ⁽²⁾..., m ^(K)The channel code of corresponding each SF=16 forms.In each time slot that belongs to the 3rd class time slot, the non-m that this resource pool is comprised in this time slot by above-mentioned scheduling HS-PDSCH resource pool ⁽¹⁾The channel code of each idle corresponding SF=16 of training sequence deviation form.

The best resource multiplex mode is scheduler when in the embodiment of the present invention two, the K value can be for arbitrary value and the core of dispatching method in above-mentioned each time slot.Under this multiplex mode, scheduling HS-PDSCH resource pool can be divided into two sub-resource pools.Scheduler and dispatching method that the present invention proposes will be dispatched based on these two sub-resource pools.

Below provide the HSDPA scheduling flow of the embodiment of the present invention two, comprise the steps:

Step 601: determine the combination of the HS-PDSCH channel type in addition that HSDPA UE can be multiplexing.This channel type combination can only consist of first kind channel and/or the 3rd class channel.The channel type that UE can be multiplexing is only enumerated in described channel type combination, but does not relate to concrete multiplexing which channel.

Step 602: determine whether to consider the multiplexing ability of UE support resource in resource multiplex.

The scheduling of step 603:HSDPA scheduler start-up period.In any one subframe " n " subsequently, the HSDPA scheduler carries out a HSDPA scheduling.

In any subframe " n ", the scheduling step of HSDPA scheduler comprises:

Step 603-1: the dispatching priority of determining each HSDPA UE of " n " subframe.According to dispatching priority order from high to low, all UE are queued up.Come the top UE of formation and have the highest dispatching priority, come the rearmost UE of formation and have minimum dispatching priority.

Step 603-2: determine the HS-SCCH that can use in current subframe.In current subframe, all HS-SCCH that configure on the carrier wave be scheduled are available HS-SCCH.

Step 603-3: determine scheduling HS-PDSCH resource pool.

Resource in the scheduling HS-PDSCH resource pool of n subframe HSDPA scheduler schedules " n+d1+1 " subframe.Step 603-3 specifically comprises following sub-step:

Step 603-3-1: at first determine the resource at n+d1+1 subframe scheduling HS-PDSCH.

Step 603-3-2: because this scheduler can be realized the shared resource of various channels that multiplexing any one channel combination in all channel combinations that first kind channel and/or the 3rd class channel form of HSUPA UE comprises, therefore, in the present invention, " n+d1+1 " subframe scheduling HS-PDSCH resource pool comprises that all kinds of channels that in the scheduling HS-PDSCH resource of " n+d1+1 " subframe and step 601, determined channel combination comprises are in the shared resource of " n+d1+1 " subframe.If the some channels in certain class channel that in step 601, determined channel combination comprises leave unused in the shared resource of " n+d1+1 " subframe, the corresponding training sequence deviation of this resource is left unused; Otherwise this training sequence deviation is not just left unused.

According to above-mentioned processing, the channel group of determining in step 601 is share in the scheduling HS-PDSCH resource pool of determining " n+d1+1 " subframe that each subframe " n " is used.But in different subframes, NODEB may be in different application scenarioss, and the occupation condition of different application scene channel can be different, and the resource of therefore dispatching in the HS-PDSCH resource pool also can be different.A kind of preferably processing mode is to pre-define plurality of application scenes, and be every kind of channel combination that scene setting is corresponding.When each subframe " n " formed " n+d1+1 " subframe scheduling HS-PDSCH resource pool, the scene that judgement " n+d1+1 " subframe meets, then adopted the channel combination of determining under this scene.The constructive method of this scheduling HS-PDSCH resource pool is more flexible.Adopting this more flexibly during method, if in certain class channel that the combination of determined channel comprises, some channels leave unused in the resource that " n+d1+1 " subframe takies, the corresponding training sequence deviation of this resource is left unused; Otherwise the corresponding training sequence deviation of this resource is not just left unused.

Step 603-4: the classification of each time slot in judgement scheduling HS-PDSCH resource pool, resolve into two sub-resource pools according to the classification of time slot by above-mentioned scheduling HS-PDSCH resource pool.

The Equations of The Second Kind time slot: any one all training sequence deviation that belong in the time slot of Equations of The Second Kind is all left unused.The time slot that belongs to Equations of The Second Kind must be the time slot that belongs to the first kind.

The best mode multiplexing according to each time interval resource resolves into following two sub-resource pools by above-mentioned scheduling HS-PDSCH resource pool:

Second sub-resource pool: this resource pool consists of Equations of The Second Kind time slot and the 3rd class time slot.Within belonging to each time slot of Equations of The Second Kind time slot, this resource pool by with m ⁽²⁾..., m ^(K)The channel code of corresponding each SF=16 forms.In each time slot that belongs to the 3rd class time slot, the non-m that this resource pool is comprised in this time slot by above-mentioned scheduling HS-PDSCH resource pool ⁽¹⁾The channel code of each idle corresponding each SF=16 of training sequence deviation form.

Step 802-2: determine the HS-SCCH that can use in current subframe.In current subframe, all HS-SCCH that configure on the carrier wave be scheduled are available HS-SCCH.

Step 802-3: the scheduling HS-PDSCH resource pool of determining current n subframe.This resource pool comprises " n+d1+1 " subframe scheduling HS-PDSCH resource and the descending idling-resource of " n+d1+1 " subframe.

Step 802-4: the classification of each time slot in judgement scheduling HS-PDSCH resource pool, resolve into two sub-resource pools according to the classification of time slot by above-mentioned scheduling HS-PDSCH resource pool.

The Equations of The Second Kind time slot: any one all training sequence deviation that belong in the time slot of Equations of The Second Kind is all left unused.
