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 relates in particular to the dispatching method and the scheduler of HSDPA resource multiplex under a kind of default training sequence deviation method of salary distribution.

Background technology

Propose in another part patent application document (application number 201010149373.7) that the inventor proposes: whole resources or part resource in the resource that HSDPA UE can multiplexing other down channels except that the HS-PDSCH channel takies.Here, descending idling-resource can be considered as a kind of special down channel.Also mention in this application file: the HSDPA scheduler is once dispatched in each subframe " n ", distributes the scheduling HS-PDSCH resource of " n+d1+1 " subframe when this subframe is dispatched.Here, d1 represents the time delay that the HSDPA scheduler of NODEB is dispatched, and this time delay represents 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 following type:

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

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

This article proposes: all down channels beyond the scheduling HS-PDSCH can constitute a variety of channel combinations, can comprise any amount of first kind channel, any amount of second class 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, the resource that the channel combination that only multiplexing first kind channel and/or the 3rd class channel are formed takies.Simultaneously, can adopt special default training sequence deviation (Midamble Shift) configuration mode and default training sequence deviation configuration mode to distribute training sequence deviation for the UE that is 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 only just can be supported under the situation of revising the 3GPP agreement, and can only be supported the UE of higher 3GPP protocol version to support in the future; And the training sequence deviation configuration mode that default training sequence deviation configuration mode is the UE of present any version all will be supported.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 one

At present, the training sequence deviation number K of sub-district is K=8 by default configuration.Therefore, at first introduce scheduler and dispatching method under HSDPA resource multiplex mode of the present invention and this resource multiplex mode at this configuration.

Is K=8 and when adopting default training sequence deviation configuration mode, the mapping relations in the sub-district between OVSF channel code and the training sequence deviation as shown in Figure 1 at the training sequence deviation number K of sub-district by default configuration.Among Fig. 1, m ⁽ⁱ⁾, i=1,2 ... .., i training sequence deviation of 8 expressions;

The expression spreading factor is j channel code in the channel code of SF, SF=1, and 2,4,8,16, j=1,2 ..., SF;

In symbol " * " represent that this channel code is a supplemental channel code.Whether do not distinguish channel code at this paper is supplemental channel code.

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

(1) with the channel code of SF=1

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

(2) will

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

(3) each training sequence deviation m ⁽¹⁾, m ⁽²⁾..., m ⁽⁸⁾The channel code of corresponding two SF=16 is shown in rightmost row among Fig. 1.Distribute to a UE for one in two channel code of the same training sequence deviation of correspondence, then the one other channel sign indicating number just can not be distributed to other UE, perhaps this channel code is distributed to same UE, perhaps throws aside.Otherwise, two UE can occur and 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 the resource multiplex between this time slot realization HSDPA UE, the resource multiplex flow process that the embodiment of the invention one proposes comprises the steps: as shown in Figure 2

(1) step 201: with the channel code of 1 SF=1 of this time slot

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

(2) step 202: with 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 that a UE.

According to above-mentioned flow process, in any one descending time slot that is scheduled, between each HSDPA UE, distribute the channel code of 1 SF=1 on the carrier wave that any one is scheduled in the sub-district 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 resource 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 present prior art 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) with 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 distributes the channel code resource of 1 SF=1 in this time slot between each HSDPA UE.Under this mode, the resource sum that can distribute to each UE is the pairing resource of channel code of 16 SF=16.And under this mode, only support to dispatch a UE at this time slot.

(2) with 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.Because 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 distributes the channel code of 16 SF=16 in this time slot between each HSDPA UE

Under this mode, the resource sum of distributing to each UE is the channel code resource 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 constituting K=8 in the following manner is at the scheduling HS-PDSCH of each subframe " n " resource pool.

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

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

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

● first kind time slot: if in a time slot training sequence deviation m ⁽¹⁾Leave unused, then this time slot belongs to first kind time slot." training sequence deviation in a time slot (such as: m ⁽¹⁾) leave unused " be meant: this training sequence deviation in this time slot (such as: m ⁽¹⁾) pairing channel code belongs to scheduling HS-PDSCH resource and idle downlink resource, is not assigned to other down channels; Perhaps, though 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 a first kind time slot.

The second class time slot: if all training sequence deviation are all left unused in a time slot, then this time slot belongs to the second class 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, then this time slot necessarily belongs to the second class time slot.The time slot that belongs to the second class 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, has only the part training sequence deviation to leave unused.If have only 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 the time slot, then 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 second class 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 is made 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 is made of the second class time slot and the 3rd class time slot.In each time slot that belongs to the second class time slot, this resource pool is by the channel code of 14 SF=16

With 7 training sequence deviation m ⁽²⁾..., m ⁽⁸⁾Constitute.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 pairing SF=16 of training sequence deviation constitute, also promptly constitute by the slack resources in the resource of various channel occupancies in scheduling HS-PDSCH resource, idle downlink resource and the channel appointed combination.

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.

Illustrate the formation in above-mentioned scheduling HS-PSCH resource pool and child resource pond below.

The Typical Disposition of 3:3 is adopted in the sub-district, and TS4-TS6 is a descending time slot.In each subframe, scheduling HS-PDSCH resource pool is made of the resource of the various channel occupancies that comprise in scheduling HS-PDSCH resource and the channel appointed combination.The whole resources that comprise TS4 and TS5 in each subframe scheduling HS-PDSCH resource.Include only idle downlink resource in the channel appointed combination.In each subframe, idle downlink resource comprises: 8 channel code of TS6

Other channel code of TS6 are used to distribute following down channel.

(1) TS6 Be used for allocation of downlink dedicated physical channels (DL DPCH);

(2) TS6 Be used to distribute High-Speed Shared Control Channel (HS-SCCH);

(3) TS6

Be used for distributing enhancing dedicated channel hybrid automatic repeat request indication channel (E-HICH);

(4) TS6

Be used for distributing enhancing dedicated channel absolute grant channel (E-AGCH).

Because TS6's

Be used to distribute 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 the downlink resource of free time

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

Constitute.Represent this scheduling HS-PDSCH resource pool with table 1.In the table 1, every row are represented 1 time slot; Each row of every row is represented 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 second class 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 the table 1, shown in table 2 and table 3.Wherein, table 2 illustrates first child resource pond and is made 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⁾Constitute.Second sub-resource pool is made of TS4, TS5 and TS6.Table 3 is illustrated in second resource pool, and in each time slot in the second class 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⁾Constitute; In the 3rd class time slot TS6, this child resource pond is by 8 channel code of TS6 in the above-mentioned scheduling HS-PDSCH resource pool With 4 the training sequence deviation " ms corresponding with these channel code ⁽⁵⁾..., m ⁽⁸⁾Constitute.

But, if TS6

Or m ⁽¹⁾Be not assigned to DL DPCH, then in this resource pool, TS4, TS5 and TS6 belong to first kind time slot; TS4 and TS5 belong to the second class time slot; TS6 belongs to the 3rd class time slot.First child resource pond is made of TS4, TS5 and TS6, and is 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 the carrier wave with the resource in multiplexing first child resource pond of time division way, with the resource in time-division and multiplexing second the sub-resource pool of sign indicating number branch mode.

When distributing resource in first child resource pond for a UE, several slots can only be distributed to UE.Because each time slot includes only a channel code Therefore, when giving the UE Resources allocation, only need determine that the number of time slot of distributing to UE gets final product in first child resource pond.

Take on the UE that is scheduled on each child resource pond and another child resource pond and constitute the resource multiplex relation between the UE of same asset.Such as: TS4 in first child resource pond has been distributed to UE1, dispatched UE2 now, desire is distributed to UE2 with 14 channel code of TS4 in second sub-resource pool.Then constitute the resource multiplex relation between UE1 and the UE2.

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

When UE is very strong to the detectability of downstream signal, even the multiplexing identical resource in other UE and it is arranged, when UE also can correctly detect the downstream signal of oneself, as long as the wireless channel between two UE is inequality, two UE just can multiplexing identical resource.Such as: the wireless channel of UE1 and UE2 is different, and it is just passable then directly 14 code channels of TS4 to be distributed to UE2.NODEB carries out channel estimating according to the received signal of the up channel of each UE, obtains the channel estimating of each UE on each antenna of NODEB side.Can obtain the down beam shaping vector of UE according to the channel estimating of each 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 and incomplete same then think: the wireless channel between two UE is inequality.

(2) if the down beam shaping vector of two UE is inequality, then think: the wireless channel between two UE is inequality.

When UE very weak to the detectability of downstream signal, if the multiplexing identical resource in other UE and it is 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 do not give UE2 with the channel code resource allocation of 14 SF=16 of TS4, can give UE2 with the resource allocation of other time slots.When a little less than the wireless channel correlation of the wireless channel of UE2 and UE1, just can give UE2 with the resource allocation of TS4.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.

Adopt when having introduced K=8 above 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 the resource multiplex mode of the best.Can dispatch at these two sub-resource pools 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 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 be made 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 in resource multiplex, to consider the multiplexing ability of UE support resource.

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 inequality.

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 comprises the steps: as shown in Figure 4

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 lined 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 sees also existing document.Because calculating the method for the dispatching priority of each UE is not content of the present invention, repeats no more here.

Step 303-2: determine the HS-SCCH that can use in current subframe.In current subframe, all HS-SCCH that dispose on the carrier wave that is 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 substep:

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

RNC disposes to the HS-PDSCH resource pool of UE and constitutes for the semi-static HS-PDSCH of each UE and scheduling HS-PDSCH resource by configuration." n+d1+1 " subframe scheduling HS-PDSCH resource equals to dispose the resource that forecloses and obtain to the resource that the HS-PDSCH resource pool of UE the semi-static HS-PDSCH of each UE in " n+d1+1 " subframe is taken from RNC.

Step 303-3-2: because this scheduler can be realized the shared resource of various channels that any one channel combination in multiplexing all channels combination that is made of first kind channel and/or the 3rd class channel 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 comprise in the determined channel combination in the scheduling HS-PDSCH resource of " n+d1+1 " subframe and the step 301 are in the shared resource of " n+d1+1 " subframe.

If some channels leave unused in the resource that " n+d1+1 " subframe takies in certain the class channel that comprises in this channel combination, then corresponding with this resource training sequence deviation is 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 therefore the resource of dispatching in the HS-PDSCH resource pool also can be different.A kind of preferable processing mode is, pre-defined plurality of application scenes, and be the channel combination of every kind of scene setting correspondence.When each subframe " n " constitutes " n+d1+1 " subframe scheduling HS-PDSCH resource pool, judge the scene that " n+d1+1 " subframe satisfies, adopt the channel combination of determining under this scene then." n+d1+1 " subframe scheduling HS-PDSCH resource pool comprises that all kinds of channels that comprise in the scheduling HS-PDSCH resource of " n+d1+1 " subframe and the combination of determined channel are in the shared resource of " n+d1+1 " subframe.

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

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

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 second class time slot: any one belongs in the time slot of second class all training sequence deviation and all leaves unused.

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

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

First child resource pond: this resource pool is made 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.

Constitute.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 pairing SF=16 of training sequence deviation constitute.

Preferably, dispatching each descending time slot that the HS-PDSCH resource pool may comprise, not with m ⁽¹⁾Pairing channel code is distributed to the down channel beyond the scheduling HS-PDSCH.

Step 303-5: begin to dispatch UE one by one 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 UE of scheduling, from all available HS-SCCH, select a HS-SCCH to distribute to UE.

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

This step determines to distribute to the HS-PDSCH of UE according to following substep:

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 of the channel code of the needed SF=16 of all HS-DSCH data that is used to carry this UE

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

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

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.

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

When determining that according to step 302 needs are investigated the ability of UE in resource multiplex, the correlation between the wireless channel of the UE that is 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 that is 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 that is scheduled is exactly the UE that carries on some first kind down channels, this time slot can not be used for UE.

If before this UE, when this time slot had the UE that is successfully dispatched, when determining that according to step 302 needs are not investigated the ability of UE in resource multiplex, whether investigation was identical at the wireless channel of the wireless channel of each UE that is 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, then this time slot can not be used for UE in this first child resource pond.Here, describedly be meant by the UE that successfully dispatched: 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 quilt is successfully dispatched in this descending time slot.

If before this UE when this time slot has the UE that is successfully dispatched, when determining that according to step 302 needs are investigated the ability of UE in resource multiplex, investigate the correlation of the wireless channel of the wireless channel of each UE that is 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, if can not determine that this time slot can not be used for UE, then this time slot can be used for UE.

According to the method described above, can determine each time slot that this UE can use in first child resource pond, 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 is to rounding on the x, that is: selection is greater than the smallest positive integral of x.

The HS-PDSCH number of time slot that each UE can support is restricted.The UE that has can support the HS-PDSCH of U=2 time slot; The UE that has 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, select Y time slot in the time slot that need in first child resource pond, can use to this UE.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} represent to get the minimum value among T, Z and the U.With the resource of Y time slot in first child resource pond alternative HS-PDSCH as UE.

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

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

Owing to constituting resource multiplex, the UE that uses same asset in the UE in second sub-resource pool and first child resource pond concerns, if when in first resource pool the UE that is successfully dispatched being arranged before this UE, 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 that is scheduled.

Whether when determining that according to step 302 needs are not investigated the ability of UE in resource multiplex, it is identical with the wireless channel of the UE that is successfully dispatched in first resource pool to investigate the wireless channel of the UE that is scheduled.If identical, then the resource in each descending time slot of taking of the UE that this quilt is successfully dispatched in second sub-resource pool can not be used for UE.If inequality, then the resource in each time slot of taking of the UE that this quilt is successfully dispatched in second sub-resource pool can be used for UE.

When determining that according to step 302 needs are investigated the ability of UE in resource multiplex, investigate between the wireless channel of the wireless channel of the UE that is 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.

Identical or correlation is very strong such as the wireless channel of: the wireless channel of the current UE that is scheduled and a UE who is successfully dispatched, employed each descending time slot of UE of then will this quilt in second sub-resource pool successfully dispatching removes.For another example: before the current UE that is 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 current UE that is scheduled is only identical with the wireless channel of first UE or correlation when very strong, in second sub-resource pool, TS3 to be removed, all resources in the TS3 all can not be used for the current UE that is scheduled; The resource of TS4 and TS5 can be that the current UE that is scheduled uses in second sub-resource pool.If the wireless channel of the current UE that is scheduled is just identical with the wireless channel of second UE or correlation when very strong, in second sub-resource pool, TS4 and TS5 to be removed, all resources in TS4 and the TS5 all can not be used for the current UE that is scheduled; The interior resource of TS3 can be that the UE that is scheduled uses in second sub-resource pool.

After determining the resource that this UE can use in second resource pool 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 that the channel code number of the SF=16 that comprises is not less than minimum rectangle in all rectangles of X.With this rectangle as alternative HS-PDSCH.So-called rectangle resource is meant that this resource occupies identical and continuous channel code at each time slot that takies.

If the channel code number that the maximum rectangle resource of the UE ability of selecting in the available resources to this UE in second resource pool that is no more than comprises is during all 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, then execution in step 502-4.

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

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

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

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

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

Scheduling to this UE under the following situation is failed:

When not obtaining any alternative HS-PDSCH through above-mentioned processing, the scheduling failure to this UE directly begins 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.Begin 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, the pairing training sequence deviation of each channel code that this HS-PDSCH comprises is distributed to UE from second sub-resource pool.

Step 505: the HS-SCCH that will distribute to this UE removes from available HS-SCCH, and upgrades two sub-resource pools.

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

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

After finishing above-mentioned processing, if do not have available HS-SCCH with regard to execution in step 506.If after finishing 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, with regard to execution in step 506.

After finishing above-mentioned processing, if available HS-SCCH is arranged, and have at least when comprising available resource in the sub-resource pool in two sub-resource pools, just begin 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 with distributing to HS-SCCH, the HS-PDSCH of this UE and the information of HS-SICH.

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

Embodiment two

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

The expression spreading factor is j channel code in the channel code of SF, SF=1, and 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 all is m ⁽¹⁾Just under the different K values, with m ⁽¹⁾Remaining training sequence deviation number is K-1 after removing, and this remaining training sequence deviation number is difference along with the difference of K value.And the channel code of the SF=16 of each training sequence deviation correspondence is also not all identical under different K in the remaining training sequence deviation.

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

(1) with the channel code of SF=1 Distribute to UE as HS-PDSCH, correspondingly, the training sequence deviation of distributing to UE is: m ⁽¹⁾

(2) will

Etc. one or more UE that distribute in the channel code,, correspondingly, the training sequence deviation of distributing to the channel code correspondence of UE is distributed to UE as the HS-PDSCH of 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.Shown in rightmost row among 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 of each training sequence deviation correspondence also may be 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 resource multiplex between the HSDPA UE at this time slot, this resource multiplex mode is as follows:

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

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

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

According to above-mentioned resource multiplex mode, in any one time slot that is scheduled, between each HSDPA UE, distribute the channel code of 1 SF=1 on the carrier wave that any one is scheduled in the sub-district With with m ⁽²⁾..., m ^(K)The channel code of pairing each SF=16.Under above-mentioned resource multiplex mode, the resource sum that can distribute to each UE on any one carrier wave that is scheduled in any one time slot that is scheduled is: the channel code of 1 SF=1 and and m ⁽²⁾..., m ^(K)The channel code of pairing 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 a 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 all be far from above-mentioned best resource mode the resource that can distribute big.

(1) with 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 distributes the channel code resource of 1 SF=1 in this time slot between each HSDPAUE.Under this mode, the resource sum of distributing to each UE is the pairing resource of channel code of 16 SF=16.And under this mode, each time slot only supports to dispatch 1 UE.

(2) with 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.Because 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, distribute the channel code of 16 SF=16 between each HSDPA UE on this is scheduled carrier wave Under this mode, the resource sum of distributing to each UE is the channel code resource of 16 SF=16.

Under the best resource multiplex mode of each time slot, constituting the carrier wave that is scheduled under the different K values 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 is made of in the shared resource of " n+d1+1 " subframe the various channels that comprise in this subframe scheduling HS-PDSCH resource and the channel appointed combination.If some channels leave unused in the shared resource of " n+d1+1 " subframe in a certain class channel that comprises in the channel appointed combination, then the pairing training sequence deviation of the shared resource of this channel is left unused; Otherwise the pairing training sequence deviation of the shared resource of this channel is not just left unused.

(3) 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." training sequence deviation in a time slot (such as: m ⁽¹⁾) leave unused " be meant: this training sequence deviation in this time slot (such as: m ⁽¹⁾) pairing channel code belongs to scheduling HS-PDSCH resource and idle downlink resource, is not assigned to other down channels; Perhaps, though 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 slack resources in the shared resource of scheduling HS-PDSCH resource or idle downlink resource or down channel, this time slot must be a first kind time slot.

The second class time slot: any one belongs in the time slot of second class all training sequence deviation and all leaves unused.The time slot that belongs to second class 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 slack resources in the shared resource of scheduling HS-PDSCH resource or idle downlink resource or down channel, this time slot must be the second class time slot.

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

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

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 is made of the second class time slot and the 3rd class time slot.In each time slot that belongs to the second class time slot, this resource pool by with m ⁽²⁾..., m ^(K)The channel code of pairing each SF=16 constitutes.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 pairing SF=16 of training sequence deviation constitute.

The best resource multiplex mode is the scheduler when K value can be for arbitrary value in the embodiment of the invention two 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 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 be made 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 in resource multiplex, to consider the multiplexing ability of UE support resource.

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 lined 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 dispose on the carrier wave that is 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 substep:

Step 603-3-1: at first determine 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 any one channel combination in multiplexing all channels combination that is made of first kind channel and/or the 3rd class channel 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 comprise in the determined channel combination in the scheduling HS-PDSCH resource of " n+d1+1 " subframe and the step 601 are in the shared resource of " n+d1+1 " subframe.If the some channels in certain the class channel that comprises in the determined channel combination in the step 601 leave unused in the shared resource of " n+d1+1 " subframe, then the pairing 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 therefore the resource of dispatching in the HS-PDSCH resource pool also can be different.A kind of preferable processing mode is, pre-defined plurality of application scenes, and be the channel combination of every kind of scene setting correspondence.When each subframe " n " constitutes " n+d1+1 " subframe scheduling HS-PDSCH resource pool, judge the scene that " n+d1+1 " subframe satisfies, adopt the channel combination of determining under this scene then.The constructive method of this scheduling HS-PDSCH resource pool is more flexible.Adopting this more flexibly during method, if some channels leave unused in the resource that " n+d1+1 " subframe takies in certain the class channel that comprises in the combination of determined channel, then the pairing training sequence deviation of this resource is left unused; Otherwise the pairing training sequence deviation of this resource is not just left unused.

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

The second class time slot: any one all training sequence deviation that belong in the time slot of second class is all left unused.The time slot that belongs to second class 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 with above-mentioned scheduling HS-PDSCH resource pool:

Second sub-resource pool: this resource pool is made of the second class time slot and the 3rd class time slot.In each time slot that belongs to the second class time slot, this resource pool by with m ⁽²⁾..., m ^(K)The channel code of pairing each SF=16 constitutes.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 pairing each SF=16 of training sequence deviation constitute.

Step 603-5: begin to dispatch UE one by one according to queue sequence from the highest UE of priority.

Scheduling flow to a UE is described with embodiment one, does not repeat them here.

As can be seen, embodiment one can regard the special case of embodiment two when K=8 as.K=8 is the number of training sequence deviation in the sub-district of giving tacit consent in the present TD-SCDMA system,

Embodiment three is the special cases when including only descending idling-resource during the channel of appointment in embodiment two makes up, and corresponding scheduler and dispatching method can further be simplified when including only descending idling-resource in the combination of the channel of appointment in embodiment two.Present embodiment three will propose corresponding scheduler and dispatching method.When in the channel combination, including only descending idling-resource, between support HSDPA UE, in the multiplexing scheduling HS-PDSCH resource, only support the downlink resource of multiplexing free time of HSDPA UE.

The HSDPA scheduling flow of the embodiment of the invention three comprises the steps:

Step 801: determine whether in resource multiplex, to consider the multiplexing ability of UE support resource.

The scheduling of step 802: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 802-1: the dispatching priority of determining each HSDPA UE of " n " subframe.According to dispatching priority order from high to low all UE are lined 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 802-2: determine the HS-SCCH that can use in current subframe.In current subframe, all HS-SCCH that dispose on the carrier wave that is 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: judge the classification of each time slot in the scheduling HS-PDSCH resource pool, above-mentioned scheduling HS-PDSCH resource pool is resolved into two sub-resource pools according to the classification of time slot.

The second class time slot: any one all training sequence deviation that belong in the time slot of second class is all left unused.

Step 802-5: begin to dispatch UE one by one according to queue sequence from the highest UE of priority.

Embodiment four proposes corresponding scheduler and dispatching method at following scene:

(1) the HS-SCCH number is 2

(2) only multiplexing descending idling-resource

(3) the HS-PDSCH resource pool that disposes to NODEB of RNC is made of several complete time slots, and this resource pool only is made of scheduling HS-PDSCH resource.Perhaps,, RNC constitutes by scheduling HS-PDSCH resource and SPS (semi-persistent scheduling) HS-PDSCH resource though disposing to the HS-PDSCH resource pool of NODEB,, scheduling HS-PSCH resource fixedly takies several complete time slots.

Present embodiment comprises the steps: at the dispatching method that above-mentioned typical application scene provides

Step 1001: determine whether in resource multiplex, to consider the multiplexing ability of UE support resource.

The scheduling of step 1002: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 1002-1: the dispatching priority of determining each HSDPA UE of " n " subframe.According to dispatching priority order from high to low all UE are lined 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 1002-2: determine the HS-SCCH that can use in current subframe.In current subframe, all HS-SCCH that dispose on the carrier wave that is scheduled are available HS-SCCH.

Step 1002-3: 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.According to shifting to an earlier date of present embodiment, " n+d1+1 " subframe scheduling HS-PDSCH resource is made of several complete time slots of RNC fixed configurations.

Step 1002-4: judge the classification of each time slot in the scheduling HS-PDSCH resource pool, above-mentioned scheduling HS-PDSCH resource pool is resolved into two sub-resource pools according to the classification of time slot.

Step 1002-5: begin to dispatch UE one by one according to queue sequence from the highest UE of priority.

Step 1002-5-1: when UE of scheduling, from all available HS-SCCH, select a HS-SCCH to distribute to UE.

Step 1002-5-2: calculate the needed channel code resource 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 held.According to the HS-DSCH data total amount B of this UE, NODEB calculates the number of the channel code of the needed SF=16 of all HS-DSCH data that is used to carry this UE

Before the UE that is being scheduled, during the UE that successfully do not dispatched, the channel code number that comprises of selecting to be no more than the UE ability in two sub-resource pools is not less than the rectangle of the minimum of X, and this rectangle is distributed to UE as HS-PDSCH.

If the channel code number that comprises at the rectangle of the maximum of selecting under the situation that is no more than the UE ability then will be selected this maximum rectangle all less than X, this rectangle is distributed to UE in two sub-resource pools.

Can't carry UE minimal data piece if distribute to the HS-PDSCH of UE, then, begin to dispatch next UE the scheduling failure of this UE.To the scheduling of next UE from step 1002-5-1.

Before the UE that is being scheduled, when a UE who is successfully dispatched is arranged, in two sub-resource pools, determine the available resources of the current UE that this is scheduled according to the method among the embodiment one.Then, in the resource that this UE can use in two sub-resource pools, select a part of resource allocation to give this UE.Distribute the method for HS-PDSCH the same for this UE.

Step 1002-5-3: 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 1002-5-4: 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, the pairing training sequence deviation of each channel code that this HS-PDSCH comprises is distributed to UE from second sub-resource pool.

Step 1002-5-5: after according to above-mentioned steps successfully being UE distribution HS-SCCH, HS-PDSCH, HS-SICH and the training sequence deviation that is scheduled, show: this UE is successfully dispatched.The HS-SCCH that distributes to this UE is removed from available HS-SCCH.Upgrade 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 removes from the time slot that first child resource pond comprises; As the HS-PDSCH that distributes to UE during, remove in the channel code that each channel code that the HS-PDSCH that distributes to this UE is taken comprises from second sub-resource pool from second sub-resource pool.

After finishing above-mentioned processing, if do not have available HS-SCCH with regard to execution in step 1002-5-6.If after finishing 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, with regard to execution in step 1002-5-6.

After finishing above-mentioned processing, if available HS-SCCH is arranged, and have at least when comprising available resource in the sub-resource pool in two sub-resource pools, just begin next UE in the dispatching priority formation.To the scheduling of next UE from above-mentioned steps 1002-5-1.To the scheduling of next UE two sub-resource pools based on above-mentioned renewal.

Step 1002-5-6: each UE to successfully being dispatched sends to physical layer with distributing to HS-SCCH, the HS-PDSCH of this UE and the information of HS-SICH.
