Description

The space division multiplexing method of shared channel in a kind of multichannel HSDPA system

Technical field

The present invention relates to the channel multiplexing technology, the space division multiplexing method of shared channel in particularly a kind of multichannel HSDPA system.

Background technology

In HSDPA, there is transmission channel HS-DSCH (High speed-Downlink Shared Channel) and three Physical Shared Channel that HSDPA is proprietary: HS-SCCH (High speed-Shared Control Channel), HS-SICH (High speed-SharedInformation Channel) and a HS-PDSCH (High speed-Physical Downlink SharedChannel) that HSDPA is proprietary.

RNC can support the HS-PDSCH resource pool of this sub-district of cell configuration of HSDPA for each.RNC is in the HS-PDSCH resource pool of this sub-district of configuration, and which channel code that can indicate which descending time slot belongs to this resource pool, and further indicates the total transmitting power that belongs to the descending time slot HS-PDSCH channel code of HS-PDSCH resource pool at each.RNC also can be one or more pairs of HS-SCCH of this cell configuration and HS-SICH.The every couple of HS-SCCH and HS-SICH comprise a HS-SCCH channel and a HS-SICH channel.HS-SCCH and HS-SICH by to the configuration.

Each HSDPA UE has a unique HS-DSCH, the HSDPA data of carrying this UE on this HS-DSCH.Each HSDPA UE has a HS-SCCH set and a HS-SICH set.Comprise four HS-SCCH at most in the HS-SCCH set of this UE.The HS-SICH that is comprising every HS-SCCH pairing in the HS-SCCH set with this UE in the HS-SICH of this UE set.Such as, RNC gives NodeB as a HS-SCCH and HS-SICH to configuration with HS-SCCH1 and HS-SICH1, comprises HS-SCCH1 in the HS-SCCH set of a HSDPA UE, then necessarily comprises HS-SICH1 in the HS-SICH of this UE set.For each HSDPA UE; It is right for HS-SCCH and the HS-SICH that this UE selection belongs to this UE that NodeB will dispose to its HS-SCCH and HS-SICH centering from RNC, selecteed HS-SCCH and HS-SICH HS-SCCH set and the HS-SICH set to constituting this UE.NodeB reports RNC with HS-SCCH set and the HS-SICH set of each HSDPA UE, and RNC then gives UE with HS-SCCH set and the HS-SICH set of UE through Uu message order configuration.When a HSDPA UE is scheduled, this UE will be assigned with the HS-PDSCH channel, and be assigned with the HS-PDSCH channel transmitting power.This UE data carried by data piece on the HS-DSCH will be through chnnel coding, interweave, bit stream on the HS-PDSCH of rate-matched and this UE of physical channel mapping becoming; The last bit stream of HS-PDSCH is sent out to UE according to the transmitting power that is assigned with through ovennodulation, spread spectrum and scrambling.

At each subframe " n ", the scheduler of NodeB all will once be dispatched.Through scheduling, confirm the UE that is scheduled in current subframe, and confirm following parameter for each UE that is scheduled:

1) the HSDPA UE ID of this UE;

2) from the HS-SCCH set of this UE, select a HS-SCCH to be disposed by RNC as the maximum transmission power of the HS-SCCH:HS-SCCH of the scheduling of this UE, Initial Trans is confirmed by NodeB; Adopt at HS-SCCH under the situation of closed loop descending power control (DLPC), the transmitting power of HS-SCCH is adjusted through HS-SCCH descending power control (DLPC) order that the HS-SICH with this HS-SCCH pairing sends according to UE; Do not adopt at HS-SCCH under the situation of closed loop DLPC, the transmitting power of HS-SCCH can remain Initial Trans, and Initial Trans can be configured to the maximum transmission power of this HS-SCCH by NodeB.

3) be exactly that the open loop transmit power of HS-SICH:HS-SICH of scheduling of this UE is definite with the path loss that UE estimates according to the expectation power of the HS-SICH of RNC configuration by UE with the HS-SICH of selecteed HS-SCCH pairing; When HS-SICH got into closed power control, the transmitting power of HS-SICH was confirmed by uplink power control (ULPC) order of the HS-SICH that UE sends through the HS-SCCH with this HS-SICH pairing according to NodeB.

4) from the HS-PDSCH resource pool, select the HS-PDSCH of a part of channel resource as the scheduling of this UE: the channel code resource that the HS-PDSCH of scheduling takies and the HS-PDSCH of scheduling are confirmed by scheduler in the transmitting power of its each time slot that is assigned with;

5) confirm the data on the HS-SCCH of the scheduling of this UE, transmitted: the HS-DSCH control information; This information is used for confirming the timing relationship between the HS-SICH of HS-PDSCH and scheduling of HS-SCCH, scheduling of scheduling by UE, and the decoding of the HS-PDSCH that is used to dispatch;

6) confirm timing relationship between HS-SCCH, HS-PDSCH and the HS-SICH of the scheduling of this UE: if the HS-SCCH of the scheduling of this UE sends in the n+d1 subframe; HS-PDSCH will send in (n+d1+d2) subframe, and HS-SICH will send in (n+d1+d2+d3) subframe.According to 3GPP standard, d3=2; The value of d1 is decided by the processing delay of NodeB, all is the same to all UE; The value of d2 is decided by the time slot at HS-SCCH place and the time slot that HS-PDSCH occupies; NodeB and UE can adopt to use the same method and confirm the timing relationship of these three interchannels, and the parameter that is used for the timing relationship of definite these three interchannels is known at NodeB and UE.

The scheduler of NodeB is handed down to above-mentioned definite parameter the physical layer of NodeB; The physical layer of NodeB will send to UE at the HS-SCCH of subframe " n+d1 " through scheduling with HSDPA UE ID and the HS-DSCH control information of this UE according to timing relationship; Then; According to the timing difference of the HS-PDSCH of HS-SCCH and the scheduling of scheduling, in subframe " n+d1+d2 " HS-DSCH of this UE is gone up data carried by data and send to this UE through the HS-PDSCH that dispatches.At last, NodeB will receive the HS-SICH of the scheduling of UE according to the timing difference between the HS-SICH of HS-PDSCH that dispatches and scheduling in subframe " n+d1+d2+d3 ".The HS-SICH of scheduling goes up the ACK/NACK information and CQI (channel quality indication) information of carrying this UE.From the time of 1+d2+d3 subframe is arranged between the reception that sends to HS-SICH of the transmission of HS-SCCH, HS-PDSCH.Begin to be dispatched to the time that the channel relevant with this scheduling UE all sends common needs (1+d1+d2+d3) sub-frame that finishes from scheduler.

For solving problems such as indoor covering and high-speed railway covering, introduced multi-channel system at present.In this system, a multichannel sub-district covers whole zone, and each passage covers the subregion in the whole sub-district; The isolation of the area of coverage of each passage is better, can think generally speaking, and the signal leakage that UE sends in a passage is very low to the power of other passages, can ignore the interference of other passages UE.

In existing multi-channel system, the scheduling of HSDPA UE and above-mentioned dispatching method are different.In multi-channel system, can adopt the space division multiplexing of HS-PDSCH resource to improve spectrum efficiency.That is: identical HS-PDSCH resource can be distributed to the UE that is in different passages.Here, the HS-PDSCH resource comprises: HS-PDSCH channel code resource and HS-PDSCH power resource.

But, in existing multi-channel system, do not consider the space division multiplexing of the shared channel that other HSDPA are proprietary, this makes that the availability of frequency spectrum of the shared channel that these HSDPA are proprietary is lower.

Embodiment

For making the object of the invention, technological means and advantage clearer, the present invention is explained further details below in conjunction with accompanying drawing.

In multi-channel system, different interchannel interference are very little, and when the base station utilized the passage at each UE place to carry out signal transmission and reception, the interference that the UE on other passages receives was very little.Therefore, can be at different interchannels, multiplexing identical shared channel resources, and utilize the passage at each UE place to carry out signal transmission and reception.Based on this, basic thought of the present invention is: through the space division multiplexing of shared channel in the multi-channel system, improve frequency spectrum resource utilization rate.

Fig. 1 is the overview flow chart of shared channel space division multiplexing method in the multichannel HSDPA system provided by the invention.As shown in Figure 1, this method comprises:

Step 101 timing relationship of HS-SICH of HS-PDSCH and scheduling of HS-SCCH, the scheduling of scheduling is set in advance, and said timing relationship is all identical to each scheduling of all UE.

In the UE of existing HSDPA system scheduling, between the different UEs or between the scheduling of different subframes, the timing relationship between the HS-SICH of the HS-SCCH of scheduling, the HS-PDSCH of scheduling and scheduling can be different.And in the present invention, if the timing relationship between the different UEs is different, scrappy HSDPA resource may appear, for example:

In the scheduling of current subframe " n ", suppose that 8 UE are scheduled.Timing relationship between three physical channels of preceding 7 UE is just the same, and the timing relationship of three physical channels of the 8th UE and other 7 UE are different.The HS-SCCH subframe of the scheduling of UE1～UE7 is all sent in subframe " n+d1 ", and the HS-PDSCH of the scheduling of UE1～UE7 sends in subframe " n+d1+d2 ", and the HS-SICH of the scheduling of UE1～UE7 sends in subframe " n+d1+d2+d3 ".But the HS-SCCH subframe of the scheduling of UE8 is sent in subframe " n+d1+1 ", and the HS-PDSCH of the scheduling of UE8 sends in subframe " n+d1+d2+1 ", and the HS-SICH of the scheduling of UE8 sends in subframe " n+d1+d2+d3+1 ".For UE8, the HS-SCCH of the scheduling of this UE is not scheduled in the resource of subframe " n+d1 ", forms scrappy HS-SCCH resource; The HS-PDSCH of the scheduling of UE8 is not scheduled in the resource of subframe " n+d1+d2 ", forms scrappy HS-PDSCH resource; The HS-SICH of the scheduling of UE8 is not scheduled in the resource of subframe " n+d1+d2+d3 ", forms scrappy HS-SICH resource.When dispatching, the HS-SCCH resource that the scheduler of NodeB can be dispatched is because the existence of processing delay can only be " n+d1+1 " subframe or the later HS-SCCH resource of this subframe to NodeB in next subframe " n+1 "; The HS-PDSCH resource that can dispatch can only be " n+d1+d2+1 " subframe and the later HS-PDSCH resource of this subframe; The HS-SICH resource that can dispatch can only be " n+d1+d2+d3+1 " subframe or the later HS-SICH resource of this subframe.Therefore, the scrappy HSDPA resource that causes of UE8 has been wasted.

In the present invention, if timing relationship is different between the scheduling of different subframes, then may cause the conflict between the scheduling resource of different subframes.For example:

Suppose at " n " only to have dispatched UE1 when subframe is dispatched.And confirm: the HS-SCCH of the scheduling of this UE 1 is that HS-SCCH1 and HS-SCCH1 are positioned at time slot 3, and the HS-SICH of scheduling is and the HS-SICH1 of HS-SCCH1 pairing that the HS-PDSCH of the scheduling of this UE occupies whole time slot 5 and time slot 6.The HS-SCCH1 of this UE will send in subframe " n+d1 ", and the HS-PDSCH of scheduling sends in subframe " n+d1+1 ", and HS-SICH1 sends in subframe " n+d1+d3+1 ".When subframe is dispatched, also only dispatched UE1 at " n+1 ".And confirm: the HS-SCCH of the scheduling of this UE is HS-SCCH1, and the HS-SICH of scheduling is HS-SICH1, and the HS-PDSCH of scheduling occupies whole time slot 6.In " n+1 " subframe, variation has taken place the timing relationship of HS-SCCH1, HS-PDSCH and HS-SICH1: HS-SCCH sends in subframe " n+d1+1 ", and the HS-PDSCH of scheduling sends in subframe " n+d1+1 ", and HS-SICH is at subframe " n+d1+d3+1 ".Like this, the HS-PDSCH and HS-SICH generation resource contention that confirm during at " n+1 " subframe scheduling with this UE respectively of the HS-SICH1 of the scheduling HS-PDSCH that when " n " subframe scheduling, confirms of this UE and scheduling: the HSDPA resource of same subframe is repeated to dispatch in different subframes.

Consider above-mentioned situation; Be the conflict between the scheduling resource of avoiding occurring scrappy HSDPA resource and different subframes; Among the present invention; When NodeB is provided with the timing relationship of HS-SICH of HS-PDSCH and scheduling of HS-SCCH, scheduling of scheduling, all identical in the scheduling of each subframe to all UE in this sub-district.

Step 102 is confirmed the passage that each UE belongs to according to the reception signal of each UE up channel, and confirms priority query according to the dispatching priority of each UE.

Step 103; According to the priority query that confirms in the step 102; Be followed successively by the HS-SCCH of each UE allocation schedule and the HS-PDSCH resource of scheduling; And will with the HS-SICH of the HS-SCCH of the said scheduling of each UE pairing HS-SICH as the scheduling of this UE, and arbitrary HS-SCCH or arbitrary HS-PDSCH resource allow to be assigned on N the different passages, on same passage, only allows to distribute once.Here, the HS-PDSCH resource comprises: the channel code resource of HS-PDSCH and the power resource of HS-PDSCH.

Wherein, N is the natural number smaller or equal to total number of channels in the sub-district.

In this step,, be followed successively by each UE allocation of channel resources may according to priority query.When carrying out channel resource allocation; Can carry out space division multiplexing, arbitrary HS-SCCH, HS-SICH or arbitrary HS-PDSCH resource allow to be assigned on N the different passages, on same passage, only allow to distribute once; That is to say; Two UE that only belong to different passages just can be assigned with same channel resource, when the passage of two UE exists when overlapping, can not be assigned with same channel resource.The distribution of HS-PDSCH comprises: distribute the channel resource of HS-PDSCH and be each time slot allocation power resource that is assigned with of HS-PDSCH.In addition, because HS-SCCH and HS-SICH match, therefore when carrying out channel resource allocation,, promptly can the HS-SICH with its pairing be distributed to corresponding UE as long as confirmed HS-SCCH.When carrying out the space division multiplexing of HS-SCCH and HS-SICH, should select the HS-SCCH and the HS-SICH of the current least number of times that is re-used.For example:

Sub-district has four couples of HS-SCCH and HS-SICH right, is numbered: first pair to the 4th pair.Scheduler at current subframe NodeB is dispatched, and has dispatched three UE:UE1, UE2 and UE3.First three of sub-district used by UE1, UE2 and UE3 respectively HS-SCCH and HS-SICH.UE4 is scheduled now, and the HS-SCCH set of UE4 comprises whole HS-SCCH of this sub-district.Owing to have three HS-SCCH to be used in the HS-SCCH of the UE4 set by other UE; UE3 should be preferentially from remaining not selected the used HS-SCCH of other UE; Such HS-SCCH has only one, and the space division multiplexing number of times of this HS-SCCH is " 0 ".UE4 is merely able to select the 4th couple of HS-SCCH and HS-SICH to as the HS-SCCH of the scheduling of this UE and the HS-SICH of scheduling.

The scheduler of NodeB can then be dispatched next UE:UE5.If the HS-SCCH of UE5 set includes only the first couple and second couple of HS-SCCH and HS-SICH of this sub-district.And suppose UE 1 at passage 1 and passage 2, and UE2 is at passage 3, and UE3 and UE4 are at passage 4, and UE5 is at passage 5.Because UE5 place passage is different with the passage that UE1 and UE2 belong to, so UE5 can be right with UE1 or UE2 space division multiplexing HS-SCCH and HS-SICH.Because UE 1 takies two passages, the first couple of HS-SCCH and HS-SICH are to by the number of times of space division multiplexing being: 2.Because UE2 takies a passage, the second couple of HS-SCCH and HS-SICH are to being 1 by the number of times of space division multiplexing.Therefore, should to select the space division multiplexing number of times be 1 the second couple of HS-SCCH and HS-SICH to UE5.

Step 104; Timing relationship according to step 101 setting; Utilize the passage at each UE place, HS-SCCH and HS-PDSCH resource through for the scheduling of this UE distribution issue control data and information data; And utilize the passage at each UE place, receive the status data that the HS-SICH of corresponding UE through the scheduling that distributes for this UE feeds back.

Through step 103, realized waiting to dispatch the process of UE allocation of channel resources may, and the resource of distributing can be multiplexing at different interchannels for each.This step promptly utilizes the channel resource of this distribution to carry out the transmission of respective channel data.

In channel data transmission process, one side need be transmitted according to the timing relationship of setting in the step 101, and on the other hand, the passage that NodeB need utilize UE to belong to separately carries out the data of respective channel and sends and receive.Particularly, NodeB utilizes the passage at UE place, through be the HS-SCCH transmitting control data of the scheduling of its distribution, and through being the HS-PDSCH resource transmission information data of the scheduling of its distribution; Utilize the passage at UE place again, through be that the HS-SICH of the scheduling of its distribution receives status datas such as ACK/NACK that UE feeds back and CQI.

For example: in the sub-district that covers a high building, each floor is made up of one or more RRU.Isolation between each floor is very high, and each floor constitutes a passage of this sub-district.Two UE are arranged in this sub-district, and UE is in the lowermost layer in this building, and UE is top this building, and the isolation between two floors is very high.In same subframe, these two UE can identical HS-SCCH, HS-SICH and the HS-PDSCH resource pool of space division multiplexing.Specifically; Through abovementioned steps, the scheduler of NodeB is found UE1 and UE2 at different passages, and scheduler can be confirmed to dispatch UE1 and UE2 simultaneously in " n " subframe; And distribute to the HS-SCCH resource of this two UE, HS-PDSCH resource and HS-SICH resource are identical.Such as, NodeB scheduler be that the HS-SCCH of the scheduling selected of UE1 is HS-SCCH1, the HS-PDSCH of the scheduling selected for UE1 is HS-PDSCH1, for the HS-SICH of the scheduling of UE1 selection be HS-SICH1.The NodeB scheduler is that UE2 also makes same selection: the NodeB scheduler is that the HS-SCCH of the scheduling selected of UE2 is HS-SCCH1, the HS-PDSCH of the scheduling selected for UE2 is HS-PDSCH1, for the HS-SICH of the scheduling of UE2 selection be HS-SICH1.Timing relationship between HS-SCCH1, HS-PDSCH1 and the HS-SICH1 is: HS-SCCH1 sends in the n+d1 subframe, and HS-PDSCH1 will send in (n+d1+d2) subframe, and HS-SICH1 will send in (n+d1+d2+d3) subframe.But at any time slot of HS-PDSCH1, to be this HS-PDSCH1 of confirming of UE 1 can be different from this scheduler in the transmitting power of this time slot to the NodeB scheduler is the transmitting power of the HS-PDSCH1 that confirms of UE2 at this time slot.Carrying out transfer of data at corresponding channel in this step comprises:

At subframe " n+d1 ", NodeB can the RRU through being positioned at this building lowermost layer sends the control information of HS-DSCH of HSDPA UE ID and UE1 of UE1 to UE1 through HS-SCCH1.Simultaneously, at subframe " n+d1 ", NodeB can be through being positioned at the top RRU in this building sends UE2 through HS-SCCH1 the control information of HS-DSCH of HSDPA UE ID and UE2 to UE2.

Then, at subframe " n+d1+d2 ", NodeB can give UE1 according to the transmitting power of each HS-PDSCH1 time slot of distributing to UE1 through the data that HS-PDSCH1 sends UE1 through the RRU that is positioned at this building lowermost layer.Simultaneously, at subframe " n+d1+d2 ", NodeB can give UE2 according to the transmitting power of each HS-PDSCH1 time slot of distributing to UE2 through the data that HS-PDSCH1 sends UE2 through being positioned at the top RRU in this building.

At last, at subframe " n+d1+d2+d3 ", UE1 will give NodeB through ACK/NACK and the CQI data of HS-SICH1 transmission UE1.Simultaneously, at subframe " n+d1+d2+d3 ", UE2 will give NodeB through ACK/NACK and the CQI data of HS-SICH1 transmission UE2.

Because the isolation between these two UE place passages is very high; Therefore, UE1 is merely able to receive the control information of HS-DSCH that the information that the RRU of this building lowermost layer sends: UE1 receives only HSDPA UE ID and the UE1 of the UE1 that NodeB sends through HS-SCCH1.UE2 is merely able to receive the control information of HS-DSCH that the information that the top RRU of this floor sends: UE2 receives only HSDPA UE ID and the UE2 of the UE2 that NodeB sends through HS-SCCH1.

Suppose the information of UE1 on can correct decoding HS-SCCH1; UE1 is through the ID of the UE1 that carries on the HS-SCCH1 so; Confirm that this HS-SCCH1 sends to it, UE1 can be confirmed subframe number " n+d1+d2 " and the subframe number " n+d1+d2+d3 " of the HS-SICH1 that dispatches of the HS-PDSCH1 of scheduling by the subframe number " n+d1 " of the HS-SCCH1 of scheduling.Then, UE1 will receive NodeB sends to UE1 through HS-PDSCH1 data through the RRU that is positioned at this building lowermost layer.At last, UE1 will give NodeB through ACK/NACK information and the CQI information of HS-SICH1 transmission UE1.This information will be received by NodeB through the RRU that is positioned at this building lowermost layer.

Suppose the information of UE2 on can correct decoding HS-SCCH1, UE2 confirms that through the ID of the UE2 that carries on the HS-SCCH1 this HS-SCCH1 sends to it so.UE2 can be confirmed subframe number " n+d1+d2 " and the subframe number " n+d1+d2+d3 " of the HS-SICH1 that dispatches of the HS-PDSCH1 of scheduling by the subframe number " n+d1 " of the HS-SCCH1 of scheduling.Then, UE2 will receive NodeB sends to UE2 through HS-PDSCH1 data through being positioned at the top RRU in this building.At last, UE2 will give NodeB through ACK/NACK information and the CQI information of HS-SICH1 transmission UE2.This information will be received by NodeB through being positioned at the top RRU in this building.NodeB detects the HS-SICH that two floor RRU receive respectively, just can obtain ACK/NACK and CQI information that two UE send respectively.Such as, lowermost layer has 1 RRU, and top have two RRU.1 RRU of NodeB through lowermost layer receives the HS-SCCH1 that UE1 sends, and detected by the reception signal of this RRU, can obtain the HS-SICH information that UE1 sends: the ACK/NACK of UE1 and CQI.NodeB receives the HS-SCCH1 that UE2 sends through top two RRU, is detected by the reception signal of this two RRU, can obtain the HS-SICH information that UE2 sends: the ACK/NACK of UE2 and CQI.

So far, the space division multiplexing method overall procedure in the multichannel HSDPA system of the present invention finishes.

Can be seen by above-mentioned space division multiplexing method: HS-SCCH, HS-SICH and HS-PDSCH can be by space division multiplexings.Because identical HS-SCCH, HS-SICH and HS-SCCH all can be assigned on N the different passage; And each HS-SCCH takies the code channel of two SF16, and each HS-SICH takies the code channel of 1 SF16, therefore; Can save the channel resource of sub-district, improve the utilance of cell channel.Here, the space division multiplexing of HS-PDSCH comprises: the space division multiplexing of HS-PDSCH channel code resource and the space division multiplexing of HS-PDSCH power resource.

Below through the embodiment of embodiment one explanation the present invention in the HSDPA system.

Embodiment one:

Can confirm the number of active lanes of each sub-district and each sub-district through the network planning.A multichannel sub-district, establishing this sub-district has M passage.Isolation is very high between each passage, between different passages, can carry out space division multiplexing to the shared channel of HSDPA.Shared channel by the greatest coefficient of space division multiplexing is: M.That is: HS-SCCH/HS-SICH/HS-PDSCH can be used by M passage simultaneously.

With indoor overlay environment is example, and the space division multiplexing method of concrete present embodiment comprises following processing:

Step 1 at current subframe " n ", according to the reception signal of the up channel of each UE, is confirmed the passage at each UE place.A UE possibly have upward signal in a plurality of passages, therefore, a UE possibly occupy a plurality of passages.

Particularly, if a UE has only a up channel at the current ascending time slot " ts " of current subframe, directly confirm the passage at this UE place through the reception signal of this up channel.

If a UE has a plurality of up channels at the current ascending time slot " ts " of current subframe, can confirm the passage at this UE place by the reception signal of all these up channels; Can be benchmark also with one of them preset up channel; Investigate the reception signal of this up channel; Confirm the passage that this UE belongs to by the reception signal of this up channel, such as: the UL DPCH with this UE is a benchmark, confirms the passage at UE place through the reception signal of this channel.

If there is up channel in current subframe in a UE at a plurality of ascending time slots, can confirm this UE place passage based on the reception signal of all up channels of all these time slots; Also can select one of them ascending time slot is benchmark; The reception signal of all up channels through this UE in this time slot is confirmed this UE place passage; Such as: select first ascending time slot of this UE, the reception signal of all up channels through this UE of this time slot is confirmed the passage at this UE place; Can be benchmark with a up channel also, through confirm the passage at UE place at the reception signal of this this up channel of time slot at the ascending time slot of selecting; Also can select a channel, confirm the passage at UE place through this channel at the reception signal of all ascending time slots; Also can confirm the passage at UE place at the reception signal of a preset ascending time slot according to this selecteed up channel, such as: with UL DPCH is benchmark, confirms the passage at this UE place according to the reception signal of first ascending time slot of UL DPCH.

In the process of above-mentioned definite UE place passage, be used for confirming that the up channel of UE place passage must be the special uplink channel of this UE; Give the shared up channel of this UE for one in current sub-frame allocation, if the up channel that this up channel also not can be used as this UE by space division multiplexing in current subframe is used to confirm the passage at this UE place.

Step 2 in " n+d0 " subframe, reports each UE place channel information the scheduler of NodeB.D0 representes processing delay.For a UE who occupies a plurality of passages, each passage that it occupies all reports scheduler.

Step 3 is dispatched according to each UE place channel information that " n+d0 " subframe reports at the scheduler of " n+d0 " subframe NodeB.In " n+d0 " subframe, the scheduler of NodeB is dispatched based on following information:

A) the HSDPA resource of sub-district comprises: the K bar HS-SCCH of current area configuration, the HSDPA resource pool of K bar HS-SICH and current area configuration; The HSDPA resource pool comprises channel code resource and the HS-PDSCH of two parts resource: the HS-PDSCH power resource at each time slot of resource pool.

B) the number of active lanes M of current area, the composition of each passage: form the RRUPATH number of each passage and the number of RRU PATH;

C) HS-SCCH of each HSDPA UE set and HS-SICH set;

D) scheduler is preserved the available situation of K bar HS-SCCH at this passage for each passage, and is for the current multiplexing number of each this HS-SCCH of bar preservation among the K bar HS-SCCH, promptly current by what channel multiplexings; In " n+d0 " subframe, when the scheduler of NodeB begins to dispatch, the multiplexing number of K bar HS-SCCH every HS-SCCH in the available situation of each passage and K bar HS-SCCH all will be initialised.

Particularly, can deposit the HS-SCCH multiplexed situation form of a K * M dimension, in " n+d0 " subframe, when the scheduler of NodeB began to dispatch, this form was initialized to " 0 " entirely.Capable m the element of the k of this form represented the available situation of k HS-SCCH of sub-district at passage m: when this element is " 0 ", and expression " available "; When this element is " 1 ", expression " unavailable "; Deposit the HS-SCCH space division multiplexing coefficient table of a K * 1 dimension again, in " n+d0 " subframe, when the scheduler of NodeB begins to dispatch, this form be initialized to entirely " 0 ".The space division multiplexing coefficient of k HS-SCCH of k element representation in this table.When the space division multiplexing coefficient of a HS-SCCH equaled the number of active lanes of this sub-district, this HS-SCCH can not be re-used again.

E) scheduler is that each passage preserves the available situation of each code channel on each time slot of HSDPA resource pool in this passage, and is kept at the available power resource situation on each time slot of this HSDPA resource pool on each passage; In " n+d0 " subframe; When the scheduler of NodeB begins to dispatch; The available situation of each code channel will be initialised on each time slot of HSDPA resource pool in each passage, in each passage on each time slot of HSDPA resource pool available power resource situation will be initialised.

Particularly, scheduler can be deposited the HSDPA channel code resource form of 16 * T dimension for each passage.Here, T representes the time slot sum that the HSDPA resource pool comprises.T time slot of the HSDPA resource pool of RNC configuration shown in the t tabulation of this form.Because the HSDPA resource pool comprises 5 descending time slots at most, minimumly comprise 1 descending time slot, so the maximum of t is 5, the minimum value of t is 1.With T time slot in the HSDPA resource pool of RNC configuration according to timeslot number sequence arrangement from small to large: the minimum time slot of timeslot number makes number one, and the time slot of timeslot number maximum rolls into last place.The time slot that comes the t position is t time slot in the HSDPA channel code resource form of 16 * T dimension.It is that the SF=16 channel code number is the channel of c at t HSDPA time slot spreading factor that the t of this form is listed as the c line display.The channel resource of each time slot can be broken down into 16 code channels of SF=16, these code channels be numbered 1 to 16.When the t of this form was listed as c element and is 0, c code channel of t time slot can be used in the expression HSDPA resource pool, when the t of this form is listed as c element and is 1, represented that c code channel of t time slot in the HSDPA resource pool is unavailable.In " n+d0 " subframe, when the scheduler of NodeB begins to dispatch, with the HSDPA channel code resource form of each passage of initialization.The initialized HSDPA channel code resource form of each passage is identical, and any element is initialised according to following mode in this form:

If the code channel that this element is corresponding belongs to the HSDPA resource pool of RNC configuration, this element is initialized to " 0 ", if the corresponding code channel of this element does not belong to the HSDPA resource pool of RNC configuration, this element is initialized to " 1 ".

Scheduler need be that also all passages preserve HSDPA power resource forms of a M * T dimension, the m line display of this form available HSDPA power resource situation on passage m.Capable t the element representation of the m of this form is at the available HSDPA power resource of t HSDPA time slot of passage m.The element that this form is initialized to every row is all identical, that is: the initialization values of t element of every row equals RNC HS-PDSCH gross power for t time slot configuration of this resource pool when configuration HSDPA resource pool.The HSDPA power resource form of initialized M * T dimension shows: the power resource of each HSDPA time slot can be by different passage space division multiplexings in the HSDPA resource pool of RNC configuration.At scheduler is when the UE that is scheduled confirms the HS-PDSCH of scheduling, needs to confirm simultaneously the power resource that channel code resource that this HS-PDSCH occupies and this HS-PDSCH occupy at each time slot that is assigned with.

Illustrate the initialization of the HSDPA channel code resource form of 16 * T dimension below:

RNC takies two time slots for the HSDPA resource pool of sub-district 1 configuration of NodeB, at first HSDAP time slot, all belongs to the HSDPA resource pool since No. 8 channel code of No. 1 channel code to the; At second HSDPA time slot, all belong to the HSDPA resource pool from No. 16 channel code of No. 1 channel code to the.Therefore, the HSDPA channel code resource form dimension of each passage is: 16 * 2.In " n+d0 " subframe, when the scheduler of NodeB began to dispatch, the HSDPA channel code resource form of each passage all was initialised.In initialized 16 * 2 dimension HSDPA channel code resource forms of each passage; Preceding 8 element values of first row all are " 0 "; Because the channel code 1-8 of corresponding first HSDPA time slot of these 8 elements; These code channels belong to the HSDPA resource pool of RNC configuration, and all the other elements of first row all are " 1 "; 16 elements of all of secondary series all are " 0 ", because the channel code 1-16 of corresponding second the HSDPA time slot of these 16 elements, these channel code all belong to the HSDPA resource pool of RNC configuration.

Illustrate the initialization of the HSDPA power resource form of the M of all passages * T dimension below:

RNC takies two time slots for the HSDPA resource pool of sub-district 1 configuration of NodeB, and at first HSDPA time slot, the HS-PDSCH gross power equals P1; At second HSDPA time slot, the gross power of HS-PDSCH equals P2.Therefore, available HSDPA power resource form is a form that dimension is M * 2: first element of every row of this form is initialized to P1, and second element of every row of this form is initialized to P2.

After successfully dispatching HS-SCCH, HS-SICH and HS-PDSCH resource for each UE; Need upgrade in available situation and current multiplexing number, the available situation (comprising: the HSDPA channel can use situation and HSDPA power can use situation) of HSDPA resource on each passage of each passage above-mentioned HS-SCCH, show that HS-SCCH, HS-SICH and the HS-PDSCH resource of having distributed are unavailable on the passage of corresponding UE place; If certain UE distributes any failure in HS-SCCH, HS-SICH and the HS-PDSCH resource; Then need not upgrade in available situation and current multiplexing number, the available situation of HSDPA resource on each passage of each passage, show that the resource of having distributed for this UE belongs on passage still available at this UE HS-SCCH.The HS-PDSCH resource of wherein, having distributed comprises: the power resource that channel code resource that HS-PDSCH occupies and the time slot that is assigned with at each HS-PDSCH occupy.When the available situation of HS-PDSCH resource each passage at UE place is upgraded, need upgrade the HSDPA power resource form of all passages of HSDPA channel code resource form and M * T dimension of 16 * T dimension of each passage at UE place simultaneously.

If UE occupies a plurality of passages: m1, m2 ...; Mm, then in the HSDPA channel resource form of 16 * T of passage " mk " dimension, the corresponding component identification of each channel that the HS-PDSCH of this UE is taken becomes " 1 "; Represent that this channel is unavailable, here, the k=1 in " mk "; 2 ..., m.

If UE occupies a plurality of passages: m1, m2 ..., mm, upgrade the HSDPA power resource form that M * T ties up according to following method:

In the HSDPA power resource form of M * T dimension with mk capable in the numerical value of t element deduct the power that the HS-PDSCH of the scheduling of this UE is assigned with at t HSDPA time slot.Here, the k=1 among the mk, 2 ..., m, t=1,2 ..., T.If the HS-PDSCH of the scheduling of this UE does not comprise t time slot, then the HS-PDSCH according to the scheduling of this UE calculates for " 0 " at the power that time slot t is assigned with.

Step 4, scheduler are calculated the dispatching priority of each HSDPA UE in " n+d0 " subframe.

In existing document, the method for the dispatching priority of calculating UE is a lot.Because this method is not a content of the present invention, repeats no more here.

Step 5, scheduler is according to the sequential scheduling UE from high to low of priority query.

When beginning to dispatch, all UE in the tabulation of the UE that can be scheduled, select the maximum UE of priority, as the UE of scheduling from this tabulation.Then, with this UE deletion from this UE tabulation.To the UE that is scheduled, execution in step 6.If had no a UE in the UE tabulation, then directly finish the scheduling of current subframe, jump to step 7.If there is not available HS-SCCH, also jump to step 7.If do not have available HSDPA code channel resource, jump to step 7 yet.If do not have available HSDPA power resource, jump to step 7 yet.Here, if the space division multiplexing coefficient of a HS-SCCH equals the number of active lanes M of this sub-district, then this HS-SCCH is unavailable.Here, if in the HSDPA of any passage channel code resource form, all HSDPA code channels are all identified " unavailable ", and then showing does not have available HSDPA code channel resource.Here, if in the HSDPA power resource form of M * T dimension, each element all is " 0 ", and just expression does not have available HSDPA power resource.

Scheduling process to each UE is all identical, is that example is explained concrete scheduling process with scheduling UE A below:

Step 61 is the HS-SCCH of the UE A selection scheduling that is scheduled and the HS-SICH of scheduling.

The mode of the HS-SCCH of allocation schedule comprises: on all passages at UE A place among the current all available HS-SCCH; Select current multiplexing number minimum and belong to a HS-SCCH in the HS-SCCH set of UE A, with the HS-SCCH of this HS-SCCH as the scheduling of current scheduling UE.If current multiplexing number is minimum and HS-SCCH that belong in the HS-SCCH set of UE A is many, then select a HS-SCCH arbitrarily; As if current all available HS-SCCH on all passages that do not exist in UE A place, then be not that UE A distributes HS-SCCH, HS-PDSCH and HS-SICH, directly carry out the distribution of HS-SCCH, HS-PDSCH and HS-SICH for the next UE in the priority query.

Particularly, when the HS-SCCH space division multiplexing coefficient table that ties up the HS-SCCH multiplexed situation form and K * 1 of in scheduler, preserving the K described in the step 3 * M dimension, then the mode of the HS-SCCH of this step allocation schedule can for:

If UE A occupies a passage m, then the number " m " with UE A place passage is an index, consults " m " row of the HS-SCCH multiplexed situation form of sub-district.In these row,, all select HS-SCCH from being designated the HS-SCCH of " 0 ", and each selecteed HS-SCCH one fixes in the HS-SCCH set of this UE.If selecteed HS-SCCH has only one, this HS-SCCH is exactly the HS-SCCH of the scheduling of this UE.If more than one of selecteed HS-SCCH consults the space division multiplexing coefficient table that these are selected HS-SCCH, select the HS-SCCH of the minimum HS-SCCH of space division multiplexing reuse as scheduling.If the HS-SCCH of space division multiplexing coefficient minimum is not unique, just select a HS-SCCH at random as scheduling.The HS-SICH that matches with this HS-SCCH is exactly the HS-SICH of the scheduling of this UE A.

If this UE A occupies a plurality of passages a: m1, m2 ..., mm just selects the HS-SCCH that in these passages, all is not used.Concrete selection mode can for: in HS-SCCH multiplexed situation form; Satisfy if k is capable: this row is at the m1 row, and m2 is listed as ...; The element of mm row all is " 0 ", and then k HS-SCCH is exactly the HS-SCCH that all is not used in this UE place passage.Selection is arranged in the HS-SCCH of the HS-SCCH set of UE in the HS-SCCH that these are selected.If selecteed HS-SCCH has only one, this HS-SCCH is exactly the HS-SCCH of the scheduling of this UE.If more than one of selecteed HS-SCCH consults the space division multiplexing coefficient table that these are selected HS-SCCH, select the HS-SCCH of the minimum HS-SCCH of space division multiplexing reuse as scheduling.If the HS-SCCH of space division multiplexing coefficient minimum is not unique, just select a HS-SCCH at random as scheduling.The HS-SICH that matches with this HS-SCCH is exactly the HS-SICH of the scheduling of this UE A.

If in the passage at UE A place, each HS-SCCH in the HS-SCCH of this UE set has been used, and does not then exist a HS-SCCH to can be used as the HS-SCCH of the scheduling of this UE.Directly return step 5, begin the scheduling of next UE.

More than be the concrete mode of the HS-SCCH of allocation schedule.Above-mentioned any HS-SCCH can be assigned on the different passages, and any here HS-SCCH can be assigned to and comprise on the different passages that two layers of meaning: RNC can be assigned on the different passages for the maximum transmission power of this HS-SCCH configuration with RNC for the channel code of this HS-SCCH configuration simultaneously.When a HS-SCCH was positioned at the UE space division multiplexing of different passages, on the passage that the UE of any this HS-SCCH of space division multiplexing belongs to, the power control of this HS-SCCH was independently.That is: when a HS-SCCH is positioned at the UE space division multiplexing of different passages; If this HS-SCCH does not adopt closed loop DLPC; On the passage that any UE of this HS-SCCH of space division multiplexing belongs to; The transmitting power of this HS-SCCH remains Initial Trans, and Initial Trans is confirmed by NodeB, can be the maximum transmission power of this HS-SCCH.When a HS-SCCH is positioned at the UE space division multiplexing of different passages; If this HS-SCCH adopts closed loop descending power control (DLPC); On the passage at any UE place of this HS-SCCH of space division multiplexing, this HS-SCCH and constitute an independently DLPC ring with the HS-SICH of this HS-SCCH pairing.If HS-SCCH of K UE space division multiplexing is arranged, then on the passage at k UE place, this HS-SCCH and constitute a DLPC ring with the HS-SICH of this HS-SCCH pairing.Like this, structure K DLPC ring on K UE place passage.Be mutually independently by the DLPC process of the HS-SCCH of space division multiplexing in each ring in this K DLPC ring.

The DLPC method of HS-SCCH can be consulted existing document in HS-SCCCH and the DLPC ring that constitutes with the HS-SICH of this HS-SCCH pairing.The formation of each DLPC ring is a content of the present invention in above-mentioned K DLPC ring, but in each DLPC ring, is not that content of the present invention can be consulted existing document by the DLPC method of the HS-SCCH of space division multiplexing.In each ring, simply be described below by the Poewr control method of the HS-SCCH of space division multiplexing:

When a HS-SCCH is positioned at the UE space division multiplexing of different passages; If this HS-SCCH adopts closed loop descending power control (DLPC); On the passage that any UE of this HS-SCCH of space division multiplexing belongs to, this HS-SCCH and the DLPC ring of HS-SICH formation that matches with this HS-SCCH.Following by the DLPC process of the HS-SCCH of space division multiplexing in this DLPC ring:

NodeB sends this HS-SCCH through the RRU on the passage at this UE place and gives UE; This UE receives the control information of NodeB through this UE of this HS-SCCH transmission through the RRU of this UE place passage; Generate the DLPC order of this HS-SCCH then according to the reception SNR of HS-SCCH, send to NodeB through HS-SICH with this HS-SCCH pairing.The DLPC order of this HS-SCCH that NodeB this UE of reception input through the RRU of this UE place passage sends through the HS-SICH with this HS-SCCH pairing.NodeB will be according to the transmitting power of this HS-SCCH of this DLPC order adjustment.

Step 62 is the HS-PDSCH resource of the UE A allocation schedule that is scheduled.

For the mode of the HS-PDSCH of UE A allocation schedule comprises:

At first; For UE A confirms all available HSDPA code channel on this UE place passage; And on the passage at this UE place, confirm available power resource for each HSDPA time slot, then based on these available HSDPA code channels and each HSDPA time slot can with power resource be the HS-PDSCH of the scheduling of this UE of UE selection.The process of confirming the HS-PDSCH of scheduling for UE comprises: the HS-PDSCH of scheduling that confirms channel code resource that the HS-PDSCH of the scheduling of this UE comprises and confirm this UE for this UE for UE is in the transmit power resource of each HSDPA time slot that is assigned with.

Confirming at HSDPA code channel all available on the passage at this UE place with after the available power resource of each HSDPA time slot on the passage at this UE place; The channel code resource of the HS-PDSCH of the scheduling of definite UE A from these HSDPA code channels; And the HS-PDSCH that from the available horsepower resource of each HSDPA time slot, confirms this scheduling is a lot of in the method for the power resource of each assigned slot, can consult pertinent literature.Based on available HSDPA code channel and each HSDPA time slot can with HSDPA power confirm that the method for HS-PDSCH of the scheduling of UE A can adopt any existing mode to realize, owing to be not content of the present invention, repeats no more here.

Below, the distribution method of a kind of HS-PDSCH of explanation that gives an example.Such as: when being the HS-PDSCH of UE allocation schedule, the channel resource of HSDPA and the power resource of HSDPA are bound.For example, the HSDPA resource pool of RNC configuration only comprises all 16 code channels of a time slot.RNC for the code channel gross power of the HS-PDSCH of this resource pool configuration is: P.In the distribution method of the HS-PDSCH that the power resource of the channel resource of HSDPA and HSDPA is bound, at first, think the HS-PDSCH gross power that each code channel is divided equally this time slot in this HSDPA time slot.Like this, the power that occupies of each HS-PDSCH code channel is: P/16.Carry out the scheduling of first UE now, suppose to confirm: need distribute 8 HS-PDSCH channel code for UE, channel code number from 1 to 8 according to CQI (channel quality indication) and the data volume of this UE of UE through the HS-SICH channel feedback.Like this; The HS-PDSCH of the scheduling of this UE comprises a HSDPA time slot; Comprise 1 to 8 channel code at this time slot, the gross power that is assigned with at the HS-PDSCH of this UE of this time slot equals all and is assigned with the power sum that code channel occupies, and this value equals: P/16*8=P/2.The power of each HS-PDSCH code channel equals P/16.

In above-mentioned HS-PDSCH scheduling, when the code channel that the HS-PDSCH that confirms UE occupies, it is also conceivable that other factors; Have such as: UE and how long not to be scheduled; Gap between the service rate of the practical business speed of UE and UE application is taken all factors into consideration the channel quality of UE and practical business speed of UE or the like.For another example, in the HS-PDSCH scheduling, the power resource of channel code resource and this code channel place time slot is not bound.The HSDPA resource pool of still establishing the RNC configuration only comprises all 16 code channels of a time slot.RNC for the code channel gross power of the HS-PDSCH of this resource pool configuration is: P.And be located in the scheduling of current subframe, have only a HSDPA UE.After the HS-PDSCH that confirms this UE according to CQI and the data volume of this UE occupies 8 channel code resources, can confirm the transmitting power of this UE again at the unique time slot of this HS-PDSCH.Owing to have only a UE in current subframe, on this time slot that can the HS-PDSCH of this UE be occupied all available power resources all distribute to this UE, in order to the quality of reception of the data that improve this UE to greatest extent.Like this, though still this UE takies 8 channel code, but the total emission power of the HS-PDSCH of this UE equals P.

Because the present invention is intended to the space division multiplexing of HS-PDSCH; After UE place passage had been confirmed power resource that available HS-PDSCH channel code resource and each HSDPA time slot can use, it was definite by fully by the HSDPA resource of space division multiplexing to belong to passage at UE.The method of HS-PDSCH of confirming the scheduling of UE A based on available HSDPA code channel and available HSDPA power is not a content of the present invention, no longer encyclopaedizes here.

If can't confirm the HS-PDSCH of this UE based on available HSDPA code channel, then this UE will not be scheduled, and directly return step 5, begin the scheduling of next UE.

The passage that is described in detail in this UE A place is below confirmed the method for available HSDPA code channel.

Particularly, when in scheduler, preserving the HSDPA resource form of the 16 * T dimension described in step 3 for each passage, then this step confirms that the mode of the HSDPA channel code that at UE A place passage is all available is:

If UE A only occupies a passage m, then the number " m " with this UE A place passage is an index, consults the HSDPA channel code resource form of " m " individual passage of sub-district.All code channels that are designated " 0 " all are available channel code in the passage of UE A place in this form.Confirm the HS-PDSCH of the scheduling of UE A based on these channel code.

After confirming the HS-PDSCH of scheduling through this step; Then show successfully and distribute HS-SCCH, HS-SICH and HS-PDSCH resource for this UE; At this moment; Also need be through in the HSDPA channel resource form of step 63 with this UE A place passage " m ", the channel of the SF=16 that the HS-PDSCH of this UE comprises all identifies " 1 ", expression " unavailable ".The channel of these " unavailable " can not be used by other UE of same passage.If can't confirm the HS-PDSCH of scheduling for this UE, then this UE just becomes " UE that is not scheduled ".Directly return step 5, begin the scheduling of next UE.

Occupy a plurality of passages: m1 at UE, m2 ..., in the time of mm, this UE can with HSDPA resource form still be the form of 16 * T dimension.If to any passage " mk ", t is listed as the capable element of k and is " 0 " in the HSDPA form of 16 * T of this passage dimension, here, k=1,2 ..., m, then this UE can with HSDPA channel resource form in t be listed as the capable element of k and be " 0 ".If there is a passage " mk " at least, k is 1,2 here; ...; Value among the m, t is listed as the capable element of k and is " 1 " in the HSDPA channel resource form of 16 * T of this passage dimension, then this UE can with HSDPA channel resource form in t be listed as the capable element of k and be " 1 ".Can be occupied the available HSDPA channel resource form of the UE of a plurality of passages in this manner simultaneously.In the time of for the HS-PDSCH of this UE allocation schedule, based on the available HSDPA channel resource form of this UE, value is for choosing the channel code of the HS-PDSCH that belongs to this UE in the element of " 0 " from this form.The HS-PDSCH of this UE must be the rectangle that is made up of for the element of " 0 " value in the HSDPA resource form that can use of this UE.The number of the row of this rectangle can be discontinuous, the every row (each time slot) that still comprise at this rectangle, and the channel code that this rectangle comprises is identical and continuous.

Occupy at UE under the situation of a plurality of passages; If for UE has confirmed the HS-PDSCH of scheduling, then also need the channel code that in the HSDPA channel resource form of this each passage of UE place the HS-PDSCH of the scheduling of this UE is occupied all be identified " unavailable " through step 63.If UE occupies a plurality of passages: m1, m2 ..., mm, the HS-PDSCH of this UE comprises c code channel of t time slot, then c component identification with t row in the HSDPA channel resource form of mk passage becomes " 1 ", representes unavailable.Here, the k=1 among the mk, 2 ..., m.

It should be noted that: when carrying out the HS-PDSCH resource allocation; The HS-PDSCH that selects for the UE of each scheduling must be a rectangle in the available HSDPA channel resource form of this UE, the maximum number of the HSDPA time slot that the number of the row that this rectangle comprises can not can be supported greater than this UE.The number of the row that this rectangle occupies can be discontinuous.But this rectangle occupies identical channel code in each row that this rectangle occupies, and the number of the channel code that occupies is continuous.

In addition; In each scheduling to each UE; Timing relationship between HS-SCCH, HS-PDSCH and the HS-SICH is provided with in advance; In the scheduling of current subframe, need make the timing relationship between HS-SCCH, HS-PDSCH and the HS-SICH of the UE of each scheduling satisfy the timing relationship that is provided with in advance really; Because the timing difference between HS-PDSCH and the HS-SICH is fixed, the key that therefore satisfies the timing relationship that is provided with in advance is to let and satisfies the timing relationship that is provided with in advance between HS-SCCH and the HS-PDSCH of UE A, that is: the subframe number of HS-SCCH and HS-PDSCH differs " d2 " sub-frame in this scheduling.

Wherein, the value of d2 can only be 0 and 1.When d2=0, the timeslot number ts2 of the timeslot number ts1 of HS-SCCH place time slot and first time slot of HS-PDSCH necessarily satisfies formula: ts2-ts1＞=3.When the value of d2 was 1, the timeslot number ts2 of the timeslot number ts1 of HS-SCCH place time slot and first time slot of HS-PDSCH satisfied this formula: ts2-ts1＞=3 scarcely.Here, first time slot of HS-PDSCH refers to: in the time slot that HS-PDSCH occupies, and the time slot that timeslot number is minimum.

For making HS-PDSCH and HS-SCCH satisfy the timing relationship that is provided with in advance, specifically can control through the HS-PDSCH resource of allocation schedule in the step 62.Provide two kinds of methods among the present invention.Wherein, first method is: when confirming HS-PDSCH, just consider the constraint of above-mentioned d2 to the timeslot number of first time slot of HS-PDSCH, in the time slot that satisfies constraints, confirm the HS-PDSCH of this UE; Second method is: confirm HS-PDSCH earlier; According to the timeslot number of first time slot of HS-PDSCH, judge between HS-PDSCH and the HS-SCCH whether satisfy the timing relationship " d2 " that is provided with in advance then, if do not satisfy; Just do not dispatch this UE, directly dispatch next UE.

According to first method; At first from the passage at this UE A place, confirm current available HS-PDSCH channel resource according to the method in the abovementioned steps 62; Thereby form the corresponding available HS-PDSCH channel resource form of this UE A, all be arranged to unavailable with in these HS-PDSCH channel resources timeslot number not being satisfied on the time slot of constraints of d2 available channel code then.At last, in the channel resource form of the HS-PDSCH that this UE A of this renewal can use, select HS-PDSCH in all available channels.Illustrate said process below.

Be made as the definite HS-SCCH of UE A and be positioned at time slot 3, the HSDPA resource pool of RNC configuration comprises time slot 5 and 6 two time slots of time slot, and all 16 code channels of these two time slots are all in this HSDPA resource pool.In current subframe, UE A is first UE that is scheduled, and the available HSDPA channel resource form of each place passage that then this UE A is corresponding is the form of 16 * 2 dimensions, because this UE A is first UE that is scheduled, all elements all is " 0 " in the form.First time slot of HSDPA channel resource pool is shown in first tabulation of this form, and this time slot is a time slot 5; The secondary series of this form is represented second time slot of HSDPA channel resource pool, and this time slot is a time slot 6.

If the d2=0 that is provided with in advance; Satisfy the constraint of d2 for first time slot that guarantees HS-PDSCH; The available channel sign indicating number resource form of UE A place passage need be updated: time slot 5 can not be as first time slot of HS-PDSCH; Because the timeslot number ts1=3 of the timeslot number ts2=5 of time slot 5 and HS-SCCH does not satisfy: ts2-ts1=5-3＞=3, if with time slot five first time slot, d2=1 rather than d2=0 as HS-PDSCH.Therefore, the HSDPA channel resource form that can be used for this UE A need be updated, and this form still is the form of 16 * 2 dimensions after the renewal, just in the form each element of first row all by for being updated to " 1 ".

Establish the d2=1 that is provided with in advance again, the HSDPA resource pool of RNC configuration still is made up of all channel code of time slot 5 and time slot 6.UE A is first UE that is scheduled on this UE place passage, and therefore, the available HSDPA channel resource form of this UE is the form of 16 * 2 dimensions, and all elements all is " 0 " in the form.Satisfy the constraint of d2 for first time slot that guarantees HS-PDSCH; The available channel sign indicating number resource form of UE A place passage need be updated: time slot 6 can not be as first time slot of HS-PDSCH; Because the timeslot number ts1=3 of the timeslot number ts2=6 of time slot 6 and HS-SCCH satisfies: ts2-ts1=6-3＞=3; If with time slot 6 first time slot, d2=0 rather than d2=1 as HS-PDSCH.When upgrading the HSDPA channel resource form of this UE A; Because time slot 6 is not first available time slot in the HSDPA channel resource form of UE A; Therefore; The available HSDPA channel resource form that upgrades later UE A still is the form of 16 * 2 dimensions, and interior each element of this form still former capital is " 0 ".Just in the HS-PDSCH that confirms UE A, secondary series (time slot 6) can not be as first time slot of HS-PDSCH in this form.Take 16 channel code if further confirm the HS-PDSCH of this UE A, this HS-PDSCH can be made up of time slot 5 and time slot 6, takies the channel code of 1-8 at each time slot HS-PDSCH; Perhaps, HS-PDSCH is made up of 16 channel code of time slot 5; But HS-PDSCH never can be made up of 16 channel code of time slot 6.

Still suppose d2=1; And hypothesis is on the passage at this UE A place; UE A is second UE that is scheduled; The HSDPA channel code resource form that can be used for this UE A is the form of 16 * 2 dimensions, and each element of first row all is " 1 " in the form, because the code channel resource of these row has been used by first UE that is scheduled in this passage; Each element of secondary series all is " 0 " in this form, and the channel code of these row also is not used.Because time slot 6 can not be as first time slot of the HS-PDSCH of UE A, upgrade the secondary series of the available HSDPA channel resource form of this UE A according to this constraints: all elements of these row all is updated to " 1 ".Like this, all elements all is " 1 " in the available HSDPA channel resource form of this UE A.Scheduling to UE A will be based on the HSDPA channel resource form of this renewal.Like this, UE A does not have available HSDPA channel resource, so this UE A will not be scheduled.

Can make the HS-PDSCH resource of the scheduling that distributes in the step 62 satisfy preset timing relationship by the way with the HS-SCCH that distributes for this UE.It should be noted that; Above-mentioned mention according in the timing relationship about the time slot constraints of d2; Renewal to the available HS-PDSCH channel resource form on the passage of UE A place; Be not on each time slot of HSDPA resource pool that the scheduler described in the step 3 is preserved for each passage the available situation (the for example HSDPA channel code resource form of each passage) of each code channel upgrade, but to the renewal of the available HS-PDSCH channel resource form of extraction separately of scheduling UE A institute.That is to say; When UE A is dispatched; Though possible some HS-PDSCH channel resource is set to unavailablely owing to the restriction of the time slot constraints of d2, these HS-PDSCH channel resources only are unavailable for UE A scheduling HS-PDSCH resource the time, also possibly be available during for other UE scheduling HS-PDSCH resource; Therefore, can not upgrade the available situation of the code channel resource on each time slot in the HSDPA resource pool described in the step 3 according to the constraints of d2.

The passage that is described in detail in this UE A place is below confirmed the method for the power resource that each HSDPA time slot can be used.

If UE occupies a plurality of passages: m1, m2 ..., mm.The HSDPA power resource form of all passages is forms of M * T dimension, and this UE is the form of 1 * T dimension at each HSDPA time slot available horsepower resource form.The available horsepower resource of t the HSDPA time slot of passage that t element representation belongs at this UE in the available horsepower resource form of this 1 * T dimension.From the HSDPA power resource form of the M of all passages * T dimension, select in the t row m1 row element, m2 row element ... and mm row element; From these elements, select a minimum value then, this minimum value is exactly the available HSDPA power resource of t HSDPA time slot on the passage of UE place.In the available HSDPA power resource form of 1 * T of this UE dimension, let t element equal this minimum value.Here, t=1,2 ..., T.When this minimum value is 0, be illustrated in that t HSDPA time slot do not had power to use on the passage at this UE place.Even available channel code resource is arranged on this time slot, these channel code resources can not be assigned to the HS-PDSCH of this UE.Therefore; After HSDPA power resource form available on the passage that obtains this UE place; If t element is " 0 " in this form, need will above-mentioned this UE that has confirmed can with HSDPA channel resource form in all elements that is listed as of t all be arranged to " 1 ", represent unavailable.

Be based on available HSDPA power resource form on HSDPA channel resource form available on this UE place passage and this UE place passage; Success is confirmed after the HS-PDSCH of scheduling, can upgrade the HSDPA power resource form of the M * T dimension of all passages according to the power that this HS-PDSCH is assigned with at each time slot that is assigned with.Update method is following:

If UE occupies a plurality of passages: m1, m2 ..., mm.The time slot that the HS-PDSCH of this UE takies is the time slot t1 of HSDPA resource pool, t2 ..., ti ..., tn.The power that takies at the HS-PDSCH of this UE of time slot ti is: Pi.Then in the HSDPA power resource form that M * T of all passages ties up, the capable element of mk that ti is listed as deducts Pi.Here, the i=1 among the ti, 2 ..., n, the k=1 among the mk, 2 ..., m.

The above-mentioned concrete method of salary distribution that is HS-PDSCH resource among the present invention.Visible by the above-mentioned method of salary distribution, when carrying out the space division multiplexing of HS-PDSCH, can code channel be that unit carries out space division multiplexing among the present invention, make space division multiplexing more flexible, multiplexing granularity is thinner, and the availability of frequency spectrum is higher.And, can distribute in the transmitting power of each time slot HS-PDSCH.

Divide timing carrying out HS-PDSCH, need confirm HSDPA channel resource all available on all passages at the UE place that is scheduled and the available horsepower resource of each HSDPA time slot on all passages at this UE place.

At first need confirm all available HSDPA channel resource on all passages at the UE place that is scheduled according to the HSDPA channel resource form of each passage at this UE place; Then alternatively according to HS-SCCH and the preset timing relationship of HS-PDSCH; Upgrade all available HSDPA channel resource on all passages at this UE place of this UE; Confirm the available HSDPA power resource of each HSDPA time slot on all passages at this UE place then; If a HSDPA time slot does not have available power resource on all passages at this UE place, then need further to upgrade available HSDPA channel resource on all passages at this UE place: do not have on the time slot of available horsepower all available code channels be arranged to " unavailable " this.

To the distribution of HS-PDSCH based on the above-mentioned HS-PDSCH resource of having confirmed: the available HSDPA channel resource and the available horsepower resource of each HSDPA time slot on these all passages of UE place.

After successfully for UE scheduling HS-SCCH, HS-SICH and HS-PDSCH resource, execution in step 63 is carried out the renewal of respective resources form; If successfully do not dispatch above-mentioned arbitrary resource, then return the scheduling that step 5 is carried out next UE for UE.

Step 63 is set to the HS-SCCH that distributes to UE A unavailablely on the passage at UE A place, and upgrade the current multiplexing number of the HS-SCCH of this distribution; On the passage at UE A place, be set to the HS-PDSCH resource of distributing to UE A unavailable.

Particularly; HS-SCCH space division multiplexing coefficient table when the HS-SCCH multiplexed situation form of in scheduler, preserving the K described in the step 3 * M dimension and K * 1 dimension; And during the HSDPA power resource form that the HSDPA channel resource form of preserving the 16 * T dimension described in step 3 for each passage and M * T tie up, then the mode of this step can for:

If the HS-SCCH of the scheduling of UE is k HS-SCCH of sub-district, if this UE occupies N passage of sub-district, then the numerical value with k element in the space division multiplexing coefficient form of HS-SCCH adds " N ";

If UE A only occupies passage " m ", then " m " in the HS-SCCH space division multiplexing situation form of sub-district is listed as k component identification and becomes " 1 "; If this UE occupies a plurality of passage m1, m2 ..., mm, then with m1 in the HS-SCCH space division multiplexing situation form, m2 ..., k component identification of mm row becomes " 1 ".

The corresponding element of code channel resource of distributing to UE A in the HSDPA channel resource form of UE A place passage correspondence is set to " 1 ".If UE A only occupies passage " m ", the channel code that just only this UE in the HSDPA channel resource form of passage m is taken identifies " 1 ", expression " unavailable ".If this UE occupies a plurality of passage m1, m2 ..., mm, the channel code that just this UE in the HSDPA channel resource form of passage mk is occupied identifies " 1 ", expression " unavailable ".Here, k=1,2 ..., m.

In the HSDPA power resource form of M * T dimension, upgrade this form according to the power of each Time Slot Occupancy of the HS-PDSCH that distributes to this UE.Method is following: establishes UE and occupies a plurality of passages: m1, and m2 ..., mm.The time slot that the HS-PDSCH of this UE takies is the time slot t1 of HSDPA resource pool, t2 ..., ti ..., tn.The power that takies at the HS-PDSCH of this UE of time slot ti is: Pi.Then in the HSDPA power resource form that M * T of all passages ties up, mk the element that ti is listed as deducts Pi.Here, the i=1 among the ti, 2 ..., n, the k=1 among the mk, 2 ..., m.

So far, promptly accomplished distribution to HS-SCCH, HS-SICH and the HS-PDSCH of UE A.

Step 7 sends to the schedule information of all UE that are scheduled the physical layer of NodeB.The schedule information of each UE mainly comprises:

A) the HSDPA UE ID of this UE, the ID of HS-SCCH, the last data carried by data of HS-SCCH: HS-DSCH control information

B) transmitting power of the last data carried by data piece of HS-PDSCH and each HS-PDSCH time slot

C)HS-SICH?ID

D) timing relationship of HS-SCCH, HS-PDSCH, HS-SICH

Step 8; Physical layer is according to the timing relationship between HS-SCCH, HS-PDSCH and the HS-SICH; The HS-SCCH of each UE that is scheduled is sent to this UE through the RRU PATH that this UE belongs to passage in subframe " n+d0+d1 "; The HS-PDSCH of each UE that is scheduled is sent to this UE through the RRU PATH that this UE belongs to passage in subframe " n+d0+d1+d2 ", receive the HS-SICH of this UE transmission then in subframe " n+d0+d1+d2 " through the RRU PATH of this UE place passage.

So far, space division multiplexing method flow process of the present invention finishes.Above-mentioned just a kind of implementation method of HSPDA space division multiplexing.

When a Uplink Shared Channel in current subframe by N UE space division multiplexing, when NodeB detects the information that each UE sends through this channel in current subframe, need respectively to carry out the detection of this channel based on the passage at each UE place.Such as: UE1, UE2 and UE3 are at current subframe space division multiplexing HS-SICH.UE1 and UE2 are respectively in passage " 1 " and " 2 ", and UE3 is in passage " 3 " and " 4 ".The signal that then sends through HS-SICH according to the reception input UE1 of all RRU PATH of passage 1; The signal that sends through HS-SICH according to the reception input UE2 of all RRU PATH of passage 2; The signal that sends through HS-SICH according to the reception input UE3 of all RRU PATH of passage 3 and passage 4.

The time that each space division multiplexing occupies is: the 1+d0+d1+d2+d3 sub-frame, therefore, requiring during this period of time, the passage of UE does not change.Otherwise possibly cause the space division multiplexing failure.

In existing HSDPA system, when UE inserts through sending SYNC-UL,, just refuse the access of all UE, thereby greatly reduce the access probability of SYNC-UL in addition through this sequence if in detection, find collision phenomenon to m SYNC-UL.

Consider the problems referred to above, to FPACH and PRACH channel, preferably also can realize space division multiplexing among the present invention, and then improve the access probability of SYNC-UL through the repeated use on different passages.

Particularly; When the SYNC-UL that detection is used to insert; If find in the detection of m SYNC-UL sequence, to bump, that is: find that K UE possibly adopt m SYNC-UL sequence to insert simultaneously, then at first confirm the position that each collision occurs in m the SYNC-UL detection.If such position has K,, confirm the passage at the UE place of this SYNC-UL of emission in the position that each SYNC-UL occurs.If there is not the overlapping part in the passage between any two UE, then can adopt the space division multiplexing of FPACH.

In the concrete implementation procedure; If through detection to m SYNC-UL sequence; Discovery has K UE to initiate to insert request in current subframe through m SYNC-UL sequence simultaneously; And this K UE is in different passages, does not have common passage between any two UE, and then this K UE can be through multiplexing FPACH of space division multiplexing mode and PRACH.That is: the RRU PATH of the passage through k UE place sends FPACH, and this FPACH goes up the power that carries k UE and controls and synchronically controlling information, k=1 wherein, and 2 ..., K.

Since the space division multiplexing of FPACH, the subframe that the PRACH corresponding with this FPACH occurs, and K UE will send PRACH information separately through PRACH in this subframe.Sky that be to realize PRACH divides and receives, and when receiving the PRACH that k UE send, can realize the sky branch reception of PRACH like this according to the PRACH of k the UE transmission of reception input of the RRU PATH of k UE place passage.

If through finding to have K UE to initiate to insert request in current subframe through m SYNC-UL sequence simultaneously to the detection of m SYNC-UL sequence; And through the detection of m SYNC-UL being confirmed the passage at these UE places; Be not that any two UE have different passages in this K UE; But can from this K UE, select several UE (being made as the individual UE of K '); The passage at any two UE place does not exist overlappingly among the individual UE of this K ', and the passage that other UE belong among any UE and K the UE among the individual UE of this K ' do not exist overlappingly, and then the individual UE of this K ' can multiplexing FPACH of space division multiplexing mode and PRACH.That is: the RRUPATH of the passage through k UE place sends FPACH, and this FPACH goes up the power that carries k UE and controls and synchronically controlling information, wherein, k=1,2 ..., K '.The PRACH of this UE transmission of reception input of the RRU PATH through k UE place passage then.The individual UE of this K ' just can realize space division multiplexing FPACH and PRACH like this.Can improve the utilance of FPACH and PRACH resource like this, and then save channel code, improve spectrum efficiency.And under the fixing situation of FPACH and PRACH resource, can improve the access probability of UE.Promptly the place of the UE through further collision detection passage can respond those UE that occupies different passages, thereby has improved the access probability of SYNC-UL.

The above-mentioned concrete realization that is realization space division multiplexing in the multichannel HSDPA system, the space division multiplexing of this shared channel is decided by NodeB in real time, through this space division multiplexing method, can improve the utilance and the spectrum efficiency of shared channel.Simultaneously, in above-mentioned description, be the explanation that example is carried out with indoor overlay environment to space division multiplexing of the present invention, in fact, the high-speed railway scene also belongs to multi-channel system.Fig. 2 is a high-speed railway networking sketch map.

In high-speed railway scene shown in Figure 2, a sub-district is made up of the RRU PATH on a plurality of poles, two RRU PATH of suspension on each pole.As shown in the figure, sub-district B is made up of the RRU PATH on 4 poles, the pole 1 that distributes successively of the rightmost from the Far Left of sub-district to the sub-district, and pole 2 ..., pole 4.The B Far Left drives into sub-district B if a row train is from the sub-district, and the reception signal of the UE on this train is only received by the RRU PATH on the leftmost pole in sub-district.Also have the rightmost of row train B from the sub-district to drive into sub-district B, the signal of the UE on this train is only received by the rightmost RRU PATH in sub-district.In this case, the UE on two trains can the identical HSDPA resource of space division multiplexing.Because RRU PATH is very big at interval at the UE on these two trains place, be equivalent to be in different passages.In other multi-channel systems such as high-speed railway network environment, all can carry out space division multiplexing to the proprietary shared channel of HSDPA, identical under concrete implementation and the above-mentioned indoor overlay environment, just repeat no more here.

More than being merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
