Description

HS-PDSCH resource allocation methods and device among a kind of HSDPA
Technical field
The present invention relates to the 3G (Third Generation) Moblie technical field, particularly a kind of high-speed downstream bag inserts high-speed physical downlink shared channel (HS-PDSCH) (HS-PDSCH) resource allocation methods and the device in (HSDPA).
Background technology
In the prior art, on the HSDPA carrier wave, the HSDPA scheduler of base station (NODEB) is all once dispatched in each subframe.Scheduler is determined the UE that is scheduled in current subframe, and is that each UE distributes High-Speed Shared Control Channel (HS-SCCH), high-speed physical downlink shared channel (HS-PDSCH) (HS-PDSCH) and high-speed shared information channel (HS-SICH).HS-SCCH and HS-SICH by to the configuration.The High-Speed Shared Control Channel (HS-SCCH) of distributing to UE is that radio network controller (RNC) configuration is to a HS-SCCH in the HS-SCCH set of UE; The HS-SICH that distributes to UE is the HS-SICH that matches with the HS-SCCH that distributes to UE; The HS-PDSCH that distributes to UE is a part of resource or the whole resource in the HS-PDSCH resource pool, and the shared resource of HS-PDSCH of distributing to UE must be the rectangle resource.So-called rectangle resource is meant that at each shared time slot of HS-PDSCH, the channel code of distributing to HS-PDSCH is continuous and identical.
In HSDPA, the resource of channel occupancy can be unique definite with time slot and these two groups of parameters of channel code.If at each shared time slot of HS-PDSCH, the channel code of distributing to HS-PDSCH is continuous and identical, be that abscissa, channel code are with the time slot on the channel resource chart of ordinate then, the shape that the resource that HS-PDSCH takies is formed must be a rectangle.
In the prior art, HS-PDSCH resource allocation flow process comprises the steps: as shown in Figure 1
Step 101:RNC gives each HSDPA carrier wave configuration some to HS-SCCH and HS-SICH, and notifies NODEB with configuration information.
Step 102: to each HSUPA UE, on the HSUPA at this UE place carrier wave, NODEB selects the HS-SCCH set of several HS-SCCH as described UE from the HS-SCCH of this carrier wave of RNC configuration.Correspondingly, constitute the HS-SICH set of UE to the HS-SICH of the HS-SCCH pairing in the HS-SCCH set of UE with configuration.
Step 103:NODEB is with the configuration information notice RNC of HS-SCCH set and the HS-SICH set of UE; By RNC this configuration information is transmitted to UE.If the number of HS-SICH was K during the HS-SICH of the number of HS-SCCH and UE gathered in the HS-SCCH of the UE set Pair, K PairMaximum be K Pair=4.
Step 104:NODEB carries out a HSDPA scheduling at each subframe n.Determine each UE of being scheduled in current subframe by dispatching, and be that each UE that is scheduled distributes HS-SCCH, HS-PDSCH and HS-SICH.
Step 105: to each UE that is scheduled, the HS-SCCH that NODEB will distribute to this UE sends to UE; To distribute the HS-PDSCH of this UE to send to UE; And the HS-SICH of reception UE feedback.This step detailed process is as follows:
Step 105-1:NODEB will distribute to the HS-PDSCH configuration information of resource of UE in (n+d) subframe and the information of high speed descending sharing channel (HS-DSCH) the data block decoding that is used for carrying on the HS-PDSCH resource sends to UE by the HS-SCCH that distributes to UE.Here, d represents the processing delay of the scheduler of NODEB.
Step 105-2: when UE when (n+d) subframe detects NODEB and sends to its HS-SCCH, UE determines to distribute to its HS-PDSCH according to the HS-PDSCH configuration information of resource of carrying on the HS-SCCH, determines each required parameter of HS-DSCH data block decoding according to the information that is used for the decoding of HS-DSCH data block of carrying on the HS-SCCH.UE also will distribute to its HS-SICH with the HS-SICH conduct of detected HS-SCCH pairing.
Step 105-3:NODEB is according to HS-DSCH data block of HS-PDSCH resource assembling of distributing to UE.The HS-PDSCH that NODEB will distribute to UE in the n+d+d1 subframe sends to UE.Here, d1=1 represents the timing difference between the subframe that subframe that HS-SCCH sends and HS-PDSCH send.
Step 105-4:UE will receive the HS-DSCH data block that NODEB sends by HS-PDSCH in (n+d+d1) subframe.If UE is correct to this data block decoding, UE will generate affirmation (ACK) information; Otherwise, will generate non-affirmation (NACK) information.UE also will generate channel quality indication (CQI) information of HS-PDSCH according to the signal to noise ratio (snr) of HS-PDSCH.
Step 105-5:UE sends to NODEB at the HS-SICH of (n+d+d1+d2) subframe by distributing to it with the CQI information of the HS-PDSCH of up-to-date generation and the ACK information of HS-DSCH data block (to HS-DSCH data block correct decoding time) or nack message (when the HS-DSCH data block error is deciphered).Here, d2=2 represents the timing difference between the subframe that subframe that HS-PDSCH sends and HS-SICH send.
Step 105-6:NODEB receives the HS-SICH that distributes to UE in (n+d+d1+d2) subframe.When NODEB when HS-SICH detects ACK information, NODEB will no longer retransmit this data block.When NODEB detects nack message, if the retransmitted number of times of this data block does not reach maximum number of retransmissions, then NODEB will retransmit this data block; Otherwise NODEB will no longer retransmit this data block.
When the scheduler of NODEB is dispatched continuously to a UE, will use same HS-SCCH.Such as: NODEB dispatches the 1st UE continuously in n subframe and n+1 subframe, it is the 1st HS-SCCH in the HS-SCCH set of UE that NODEB gives the HS-SCCH of the 1st UE in the n sub-frame allocation, then NODEB is when the n+1 subframe is dispatched this UE once more, and it must be the 1st HS-SCCH that NODEB distributes the HS-SCCH of this UE.
For UE, UE distributes to monitoring each HS-SCCH in its HS-SCCH set in first subframe.When UE listens to 1 HS-SCCH that distributes to it when (this HS-SCCH is called a HS-SCCH) in previous subframe, UE will only monitor a HS-SCCH in current subframe.When UE when previous subframe does not listen to the HS-SCCH that distributes to it, UE will monitor each HS-SCCH in the HS-SCCH set of distributing to it in current subframe.Above-mentioned UE shows the snoop procedure of HS-SCCH set: in the prior art, UE does not support NODEB in same subframe a plurality of HS-SCCH to be distributed to described UE.
In the transmission and receiving course of above-mentioned HS-SCCH, HS-PDSCH and HS-SICH, also there is following process of carrying out synchronously:
1, HS-SCCH and HS-SICH constitute descending power control (DLPC) loop of HS-SCCH:
The signal to noise ratio (snr) of the HS-SCCH that distributes to it that the UE basis receives and the SNR desired value of HS-SCCH generate the DLPC order of HS-SCCH; Distribute to the DLPC order that transmitting power control (TPC) territory on the HS-SICH of UE is used to carry the HS-SCCH of the up-to-date generation of UE; NODEB receives the HS-SICH that UE sends, and extracts the DLPC order that HS-SICH goes up the HS-SCCH of TPC territory carrying, adjusts the transmitting power of the HS-SCCH that distributes to UE according to this DLPC order.
2, HS-SCCH and HS-SICH constitute uplink power control (ULPC) loop of HS-SICH:
NODEB will generate the ULPC order of HS-SICH according to the SNR desired value of the SNR of HS-SICH and HS-SICH when receiving the HS-SICH of UE; Distribute to the ULPC order of HS-SICH that TPC territory on the HS-SCCH of UE is used to carry the UE of the up-to-date generation of NODEB; UE receives NODEB and sends to its HS-SCCH, extracts the ULPC order that HS-SCCH goes up the HS-SICH of TPC territory carrying, adjusts the transmitting power of the HS-SICH that distributes to it according to this ULPC order.
3, HS-SCCH and HS-SICH constitute uplink synchronous control (ULSC) loop of HS-SICH:
NODEB will be according to the channel estimating of HS-SICH when receiving the HS-SICH that UE sends, or according to the channel estimating of HS-SICH with in the channel estimating of other up channels of same subframe UE, generates the ULSC order of UE; Distribute to the ULSC order that simultaneous bias (SS) territory on the HS-SCCH of UE is used to carry the UE of the up-to-date generation of NODEB; UE receives NODEB and distributes to its HS-SCCH, extracts the ULSC order that HS-SCCH goes up the UE of SS territory carrying, adjusts the Timing Advance (TA) of the HS-SICH of UE according to this ULSC order.Perhaps, UE goes up SS territory carrying on other down channels of UE in the ULSC order of UE of SS territory carrying and the same subframe to HS-SCCH ULSC order merges, and UE is according to the TA of each up channel of the ULSC order adjustment UE that merges.
4, the down beam shaping of HS-SCCH (DLBF):
NODEB will be according to the channel estimating of the HS-SICH of the UE that receives or/and the channel estimating of other up channels of UE generates the DLBF weight vector of UE.The HS-SCCH that distributes to UE will adopt the DLBF weight vector of the up-to-date generation of NODEB UE to carry out down beam shaping.
In the HSDPA system, adopt the Typical Disposition of 2:4 or 3:3 usually.Under the Typical Disposition of 2:4, the HS-PDSCH resource pool that RNC distributes to NODEB takies 4.5 time slots usually.Under the Typical Disposition of 3:3, the HS-PDSCH resource pool that RNC distributes to NODEB takies 3.5 time slots usually.Under the HS-PDSCH of the above-mentioned employing rectangle resource pool method of salary distribution, when UE is scheduled, the HS-PDSCH resource of distributing to UE takies 4 time slots (during the 2:4 configuration) or 3 time slots (during the 3:3 configuration) at most, the resource of 4.5 time slots (during the 2:4 configuration) in the resource pool or 3.5 time slots (during the 3:3 configuration) all can not be distributed to UE.Like this, have at least the HS-PDSCH resource pool of 0.5 time slot not to be fully utilized.The descending peak rate of UE is merely able to reach the 1.5Mbps that 2Mbps that 4 time slots (during the 2:4 configuration) institute can support or 3 time slots institute can support, can not reach 4.5 time slots (when 2:4 disposes) the 2.2Mbps that can support or 3.5 time slots (when 3:3 disposes) the 1.75Mbps that can support.

Description of drawings
Fig. 1 is a HS-PDSCH resource allocation schematic flow sheet of the prior art;
The NODEB that Fig. 2 proposes for the embodiment of the invention one is by the concurrent method flow diagram that will distribute to the non-rectangle HS-PDSCH resource notification UE of UE of HS-SCCH.
Embodiment
In view of the HS-PDSCH resource distribution mode of rectangle has greatly limited the descending peak rate of UE, the present invention proposes: be the descending peak rate that improves UE, and the HS-PDSCH resource that can distribute non-rectangle to UE.Such as: under 2:4 configuration, the resource of 4.5 time slots of HS-PDSCH resource pool all can be distributed to UE, under the 3:3 configuration, 3.5 time slots of HS-PDSCH resource pool all can be distributed to UE.
For realizing distributing the HS-PDSCH resource of non-rectangle, need to distribute to the non-rectangle HS-PDSCH resource notification UE of UE to UE.The present invention's proposition will be distributed to the method for the non-rectangle resource notification UE of UE, and this method comprises following content:
1, the non-rectangle HS-PDSCH resource that will distribute to UE is notified to the method for UE by HS-SCCH;
2, UE distributes to the method for its non-rectangle HS-PDSCH resource by the HS-SCCH acquisition;
3, be used to distribute DLPC method and the DLBF method of the HS-SCCH of non-rectangle HS-PDSCH resource;
4, ULPC method and the ULSC method of the HS-SICH of the ACK/NACK information of feedback non-rectangle HS-PDSCH resource and CQI information.
Below by specific embodiment above-mentioned every method is set forth respectively respectively.
For making the distribution method backward compatibility of non-rectangle HS-PDSCH resource of the present invention, for the UE that supports non-rectangle HS-PDSCH resource allocation, UE need report first Indication message to give RNC, and described first Indication message is used to show that this UE has the ability of supporting non-rectangle HS-PDSCH resource allocation.For the NODEB that supports non-rectangle HS-PDSCH resource allocation, NODEB need report second Indication message to give RNC, and described second Indication message is used to show that this NODEB has the ability of supporting non-rectangle HS-PDSCH resource allocation.For the NODEB that reports second Indication message, RNC need be transmitted to this NODEB with first Indication message of described UE.For the UE that reports first Indication message, described NODEB could give this UE with the HS-PDSCH resource distribution of non-rectangle.For described NODEB, when this NODEB did not receive first Indication message of the UE that RNC transmits, NODEB can not give UE with the HS-PDSCH resource allocation of non-rectangle.For the UE that supports non-rectangle HS-PDSCH resource allocation, when the HSDPA of NODEB scheduler is determined this UE of scheduling, and when distributing non-rectangle HS-PDSCH resource for this UE, NODEB gives UE by the non-rectangle resource notification that HS-SCCH will distribute to UE.
The scheme that the embodiment of the invention one proposes is: NODEB will distribute to the non-rectangle resource notification UE of UE by the concurrent mode of HS-SCCH.
HS-SCCH and forwarding method are exactly: the non-rectangle HS-PDSCH resource division that will distribute to UE becomes several rectangles, and the HS-PDSCH resource that sends these several rectangles in the time of by several HS-SCCH in the HS-SCCH set of distributing to UE is notified to UE respectively.Each HS-SCCH gives UE with the rectangle HS-PDSCH resource notification that division obtains.In HS-SCCH and forwarding method, a plurality of HS-SCCH can occur in same subframe and dispatch simultaneously to same UE.
Under the HS-PDSCH of non-rectangle resource distribution mode, when the HSDPA scheduler of NODEB distributes the HS-PDSCH resource of non-rectangle to UE, need to carry out following operation:
(1) determines to distribute to the non-rectangle HS-PDSCH resource of UE, and this non-rectangle HS-PDSCH resource division become several rectangles HS-PDSCH resource, select several HS-SCCH from the HS-SCCH set of UE, the rectangle HS-PDSCH resource notification that each HS-SCCH is used for division is obtained is given UE.When rectangle HS-PDSCH number of resources that division obtains greater than the HS-SCCH set of UE in during the number of HS-SCCH, from each rectangle resource that division obtains, several rectangle resources of the channel code number maximum of the SF=16 that selection comprises, the number of these several rectangle resources equal the number of HS-SCCH in the HS-SCCH set.
(2) according to the HS-SCCH that selects, the method that is identified for feeding back the HS-SICH of the ACK/NACK information of HS-PDSCH and CQI information is:
Method one: the HS-SICH of selection and selecteed HS-SCCH pairing, these HS-SICH are used to feed back ACK/NACK information and the CQI information of HS-PDSCH.When selecteed HS-SCCH is positioned at different time-gap, adopt this method.
Method two: select a HS-SICH from the HS-SICH that the HS-SCCH with selection matches, this HS-SICH is used to feed back ACK/NACK information and the CQI information of HS-PDSCH.Preferably, from the HS-SICH that the HS-SCCH with selection matches, select the HS-SICH of number minimum or the HS-SICH of number maximum.The number of this HS-SICH refers to the number of HS-SICH in the HS-SICH set.
When selecteed HS-SCCH is positioned at same time slot, adopt this method.
When but selecteed HS-SCCH is not positioned at same time slot is positioned at same time slot with the HS-SICH of each HS-SCCH pairing, also can adopt method two.When adopting method two in this case, the TPC territory of the HS-SICH that selects need be become can carry N TPC symbol simultaneously by being merely able to carry a TPC sign extended, here, N represents that selecteed HS-SCCH is positioned at the individual different time slot of N.
(3) determine the modulation system of the HS-DSCH data block of carrying on the non-rectangle HS-PDSCH resource.The method of modulation system of determining the HS-DSCH data block of carrying on the non-rectangle HS-PDSCH resource is with the method for the modulation system of the HS-DSCH data block of determining to carry on the rectangle HS-PDSCH resource.
(4) determine the HS-DSCH data block length that carries on the non-rectangle HS-PDSCH resource.This method is with the method for the HS-DSCH data block length of determining to carry on the rectangle HS-PDSCH resource.
(5) according to HS-DSCH data block length assembling HS-DSCH data block.With existing method.
(6) be identified for carrying the mixed automatic retransmission request mark (HARQ ID) of the process of HS-DSCH data block.With existing method.
(7) be identified for redundancy versions (RV) information that the HS-DSCH data block is encoded.With existing method.
(8) determine that HS-SCCH goes up the value in new data indication territory.With existing method.
(9) determine HS-SCCH cyclic sequence number.With existing method.
(10) determine to distribute to HS-SCCH, the HS-PDSCH of UE and the timing relationship between the HS-SICH: NODEB sends each selecteed HS-SCCH in the n+d subframe; By HS-SCCH's and the HS-PDSCH resource that circularizes the non-rectangle that the HS-PDSCH resource of each rectangle of UE constitutes be positioned at the n+d+d1 subframe, NODEB will send the HS-PDSCH of the non-rectangle that distribute to UE in the n+d+d1 subframe; UE will send HS-SICH in the n+d+d1+d2 subframe.In sum, under the HS-PDSCH of non-rectangle resource distribution mode, the timing relationship of each interchannel remains unchanged.
How to determine that to UE above-mentioned information (3)～(10) are the research contents of HSDPA scheduler, can consult pertinent literature by the HSDPA scheduler.Here, repeat no more.
Be described in detail as follows to the method for UE non-rectangle HS-PDSCH resource notification by above-mentioned HS-SCCH and forwarding method:
At present, the type of HS-SCCH has 9 kinds.UE uses different HS-SCCH types at different states.The user mode of every kind of HS-SCCH has clear and definite definition in the 3GPP agreement.Be the method that UE is given non-rectangle HS-PDSCH resource notification by HS-SCCH and forwarding method in the example explanation with the HS-SCCH Class1 below.
When NODEB determines according to the residing state of UE: in the time of need giving UE by the HS-PDSCH resource notification that the HS-SCCH Class1 will be distributed to UE, concurrent HS-SCCH adopts the form of HS-SCCH Class1.Following each territory of each HS-SCCH is identical in each the concurrent HS-SCCH that adopts HS-SCCH Class1 form:
The modulation system territory of (1) 1 bit: according to the modulation system that the HSDPA scheduler is determined, the method for determining this territory is with existing method.
The HS-DSCH data block length territory of (2) 6 bits: this territory method to set up is with existing method.
The mixed automatic retransmission request mark of (3) 3 bits (HARQ ID) territory: this territory method to set up is with existing method.
The redundancy versions of (4) 3 bits (RV) information field: this territory method to set up is with existing method.
The new data indication territory of (5) 1 bits: this territory method to set up is with existing method.
The HS-SCCH cyclic sequence territory of (6) 3 bits: this territory method to set up is with existing method.
Among any one concurrent HS-SCCH, the method to set up in the channel code collection territory of the gap information territory of 5 bits and 8 bits is as follows:
The gap information territory of 5 bits and the channel code collection information field of 8 bits are used for the gap information and the channel code collection information of k rectangle HS-PDSCH resource are notified to UE among k HS-SCCH; The method in gap information territory and channel code collection information field in the HS-SCCH Class1 is set with existing method according to the HS-PDSCH resource of a rectangle.
In the n subframe, NODEB determines that according to said method each concurrent HS-SCCH goes up on each territory after the loaded information bit, and NODEB just can send to UE with each HS-SCCH simultaneously in the n+d1 subframe.Wherein d1 represents the processing delay of NODEB.
When according to the residing state of UE, when adopting the HS-SCCH of other types, the HS-SCCH of other types comprises gap information territory and channel code collection territory equally.The gap information territory of all types of HS-SCCH all is 5 bits.The length difference in the channel code collection territory of dissimilar HS-SCCH, or be 6 bits or be 8 bits.
HS-SCCH's and the non-rectangle HS-PDSCH resource of distributing to UE of sending out public notice the method for above-mentioned employing HS-SCCH Class1 is expanded, just can obtain following by HS-SCCH's and forwarding method notice distribute to the method for the non-rectangle HS-PDSCH resource of UE, this method is applicable to the residing any state of UE:
When a UE was scheduled, NODEB determined the HS-SCCH type with current UE state matches of living in according to the residing state of UE from HS-SCCH Class1～HS-SCCH type 9.
The non-rectangle HS-PDSCH resource division that NODEB will distribute to UE becomes several rectangles HS-PDSCH resource.
NODEB selects several HS-SCCH from the HS-SCCH set of UE, the rectangle HS-PDSCH resource notification that each HS-SCCH is used for division is obtained is given UE.When rectangle HS-PDSCH number of resources that division obtains greater than the HS-SCCH set of UE in during the number of HS-SCCH, NODEB is from each rectangle resource that division obtains, several rectangle resources of the channel code number maximum of the SF=16 that selection comprises, the number of these several rectangle resources equal the number of HS-SCCH in the HS-SCCH set.
The pairing form of HS-SCCH type that selecteed each HS-SCCH adopts above-mentioned NODEB to determine according to UE state of living in.
NODEB is by the gap information notice UE of gap information territory among the HS-SCCH with a rectangle HS-PDSCH resource; By the channel code notice UE that this rectangle HS-PDSCH resource is shared of channel code collection territory among this HS-SCCH.Identical value is arranged in each territory of other of each selecteed HS-SCCH.
The method that gap information territory and channel code collection territory in the HS-SCCH type are set according to a rectangle HS-PDSCH resource is with existing method.
In sum, the method for the NODEB that the embodiment of the invention proposes by the concurrent non-rectangle HS-PDSCH resource notification UE that will distribute to UE of HS-SCCH comprises the steps: as shown in Figure 2
Step 201: for the UE that supports non-rectangle HS-PDSCH resource allocation, UE need report first indication information to give RNC; For the NODEB that supports non-rectangle HS-PDSCH resource allocation, need report second indication information to give RNC.First indication information that RNC need report UE is transmitted to " supports the NODEB of non-rectangle HS-PDSCH resource allocation.Described first indication information is used to show that this UE has the ability of supporting non-rectangle HS-PDSCH resource allocation, and described second indication information is used to show that this NODEB has the ability of supporting non-rectangle HS-PDSCH resource allocation
Step 202: for supporting " non-rectangle HS-PDSCH resource allocation " UE, when UE is supported the NODEB scheduling of non-rectangle HS-PDSCH resource allocation, the non-rectangle HS-PDSCH resource division that NODEB will distribute to UE becomes several rectangles, select several HS-SCCH from the HS-SCCH set of UE, the rectangle HS-PDSCH resource notification that each HS-SCCH is used for division is obtained is given UE.If the rectangle number that division obtains is greater than the sum M of HS-SCCH in the HS-SCCH set of UE, NODEB selects to comprise M the maximum rectangle of channel code number of SF=16 from the rectangle that division obtains.
Step 203:NODEB is according to the HS-SCCH that selects, and is identified for feeding back the HS-SICH of ACK/NACK information and the CQI information of HS-PDSCH.Specifically can adopt one of following two kinds of methods:
Method one: the HS-SICH of selection and selecteed HS-SCCH pairing, these HS-SICH are used to feed back ACK/NACK information and the CQI information of HS-PDSCH.When selecteed HS-SCCH is positioned at different time-gap, adopt this method.
Method two: select a HS-SICH from the HS-SICH that the HS-SCCH with selection matches, this HS-SICH is used to feed back ACK/NACK information and the CQI information of HS-PDSCH.Preferably, from the HS-SICH that the HS-SCCH with selection matches, select the HS-SICH of number minimum or the HS-SICH of number maximum.The number of this HS-SICH refers to the number of HS-SICH in the HS-SICH set.When selecteed HS-SCCH is positioned at same time slot, adopt this method.
When but selecteed HS-SCCH is not positioned at same time slot is positioned at same time slot with the HS-SICH of each HS-SCCH pairing, also can adopt method two.When adopting method two in this case, the TPC territory of the HS-SICH that selects need be become can carry N TPC symbol simultaneously by being merely able to carry a TPC sign extended, here, N represents that selecteed HS-SCCH is positioned at the individual different time slot of N.
Step 204: according to the residing state of UE, the HS-SCCH type of determining each HS-SCCH employing of selection is which kind of type in 9 kinds of HS-SCCH types.
Step 205: for each selecteed HS-SCCH, this HS-SCCH adopts the above-mentioned pairing form of determining according to UE state of living in of HS-SCCH type, according to the gap information and the channel code information of the rectangle HS-PDSCH resource of this HS-SCCH feedback, determine the gap information territory of last 5 bits of described HS-SCCH and the channel code collection territory of N bit.The value of N is decided by the length in channel code collection territory in the described HS-SCCH type.For different HS-SCCH types, N=6 or N=8.
Step 206: determine that each selecteed HS-SCCH goes up other each territories, each HS-SCCH goes up other each territories and is arranged to identical value.For the HS-SCCH Class1, other each territories comprise following each territory:
● the modulation system territory of 1 bit: determine that according to the modulation system that the HSDPA scheduler is determined the method in this territory is with existing method
● the HS-DSCH data block length territory of 6 bits: this territory method to set up is with existing method
● the HARQ ID of 3 bits (mixed automatic retransmission request mark) territory: this territory method to set up is with existing method
● the RV of 3 bits (redundancy versions) information field: this territory method to set up is with existing method
● the new data indication territory of 1 bit: this territory method to set up is with existing method
● the HS-SCCH cyclic sequence territory of 3 bits: this territory method to set up is with existing method
Step 207:, each HS-SCCH is sent to UE according to timing relationship.When NODEB when the n subframe is given above-mentioned non-rectangle HS-PDSCH resource allocation UE, each HS-SCCH that NODEB will distribute to UE in the n+d1 subframe sends to UE.Here, d1 represents the processing delay of NODEB.
The embodiment of the invention two proposes a kind of UE distributes to its non-rectangle HS-PDSCH resource by the HS-SCCH acquisition method.
When adopting embodiment one (HS-SCCH's is concurrent) notice to distribute under the situation of HS-PDSCH resource of non-rectangle of UE, the method for HS-PDSCH resource that UE obtains to distribute to it is as follows:
(1) UE need monitor each HS-SCCH in the HS-SCCH set of distributing to it in each subframe.
Every type HS-SCCH goes up loaded information bit number and not all identical.Therefore, when UE monitored each HS-SCCH in each subframe, UE at first needed HS-SCCH type definite according to the residing state of current subframe and current UE state matches of living in.
(2) if UE is not when current subframe detects the HS-SCCH that distributes to it, UE will monitor each HS-SCCH in next subframe.If UE detects N in current subframe E-AGCHWhen individual HS-SCCH distributed to it, UE will be according to this N E-AGCHIndividual HS-SCCH obtains NODEB and distributes to its HS-PDSCH resource information and HS-SICH resource information.To continue to monitor each HS-SCCH at next subframe UE.
The UE basis is at the detected N of current subframe E-AGCHIndividual HS-SCCH determine to distribute to it the HS-PDSCH configuration information of resource, being used for HS-PDSCH, to go up the method for configuration information of the information of data block decoding and HS-SICH as follows:
(1) when UE only detects a HS-SCCH, that is: N E-AGCH=1 o'clock, UE can obtain all information bits of this HS-SCCH carrying by the decoding to a detected unique HS-SCCH.The HS-SCCH type that UE adopts according to HS-SCCH goes up information bit to this HS-SCCH and resolves.By each territory that comprises in these information bits can determine HS-PDSCH configuration information, be used for the information that HS-PDSCH goes up data block decoding.Determine that according to the information bit on HS-SCCH type and the HS-SCCH HS-PDSCH configuration information and HS-PDSCH go up the together existing method of method of the information of data block decoding.Be used to feed back the HS-SICH that HS-PDSCH goes up the CQI information of data block ACK/NACK information and HS-PDSCH with the HS-SICH of this unique HS-SCCH pairing.
For the HS-SCCH Class1, the information bit on the HS-SCCH comprises following information:
The channel code collection information of (1) 8 bit
The gap information of (2) 5 bits
The modulation system of (3) 1 bits
The HS-DSCH data block length of (4) 6 bits
The HARQ ID of (5) 3 bits (mixed automatic retransmission request mark)
The RV of (6) 3 bits (redundancy versions) information
The new data indication of (7) 1 bits
The HS-SCCH cyclic sequence of (8) 3 bits number
UE will carry out demodulation and the decoding that HS-PDSCH goes up the HS-DSCH data block according to the information of determining in above-mentioned (1), (2), (3), (4), (5), (6) and (7).
(2) when UE detects a plurality of HS-SCCH simultaneously, that is: N E-AGCH＞1 o'clock, UE will be respectively resolves channel code collection territory and gap information territory on each HS-SCCH that is detected according to each HS-SCCH decode results, and UE will unite other each territories of resolving on each HS-SCCH that is detected according to the decode results of all HS-SCCH.When HS-SCCH was concurrent, the information in other each territories outside each HS-SCCH upper signal channel Ma Ji territory and the gap information territory was identical, and therefore, UE need unite parsing to other each territories of each detected HS-SCCH.
For each HS-SCCH that is detected, UE can obtain all information bits that this HS-SCCH goes up carrying by the decoding to this HS-SCCH.The HS-SCCH type that UE adopts according to this HS-SCCH can go up from this HS-SCCH determines channel code collection territory and gap information territory the information bit.UE will determine that this HS-SCCH distributes to each channel code of HS-PDSCH resource occupation of the rectangle of UE according to channel code collection territory, and UE will determine that this HS-SCCH distributes to each time slot of the rectangle HS-PDSCH resource occupation of UE according to the gap information territory.
For each HS-SCCH upper signal channel Ma Ji territory that is detected and any one information bit in each territory outside the gap information territory, determine that this information bit value among each HS-SCCH is that this information bit value is 1 number among 0 number and each HS-SCCH.If value is 0 number greater than value is 1 number, then determine: this bit is united resolves to 0; If value is 0 number less than value is 1 number, determine: this information bit is united to resolve to: 1; To equal value be 1 number if value is 0 number, selects a value in 0 and 1 at random, this information bit united resolve to the value that this is selected at random.
By the value of the information bit in other each territories outside above-mentioned associating analytic method acquisition HS-SCCH upper signal channel Ma Ji territory and the gap information territory, can obtain the information of each domain representation according to the value of each domain information bit.When HS-SCCH adopts the HS-SCCH Class1, can obtain following information according to the value of each domain information bit:
The modulation system of (1) 1 bit
The HS-DSCH data block length of (2) 6 bits
The HARQ ID of (3) 3 bits (mixed automatic retransmission request mark)
The RV of (4) 3 bits (redundancy versions) information
The new data indication of (5) 1 bits
The HS-SCCH cyclic sequence of (6) 3 bits number
When UE when same subframe detects a plurality of HS-SCCH simultaneously, the method for determining to distribute to the HS-SICH of UE has two kinds:
When detected each HS-SCCH is positioned at different time-gap, determine and the HS-SICH of detected each HS-SCCH pairing that these HS-SICH are the HS-SICH that distributes to UE.
When detected each HS-SCCH is positioned at same time slot, with the HS-SICH of detected each HS-SCCH pairing in, select the maximum HS-SICH of minimum HS-SICH of numbering or numbering as the HS-SICH that distributes to UE.
When detected each HS-SCCH is positioned at different time-gap but is positioned at same time slot with the HS-SICH of each HS-SCCH pairing, under the situation in the TPC territory of expanding HS-SICH, the HS-SICH that selects minimum HS-SICH of numbering or numbering maximum in each HS-SICH is as the HS-SICH that distributes to UE.
The embodiment of the invention three proposes a kind of DLPC method and DLBF method that is used to distribute the HS-SCCH of non-rectangle HS-PDSCH resource
Adopting the concurrent method of HS-SCCH to notify under the situation of the non-rectangle HS-PDSCH resource of distributing to UE, the DLPC loop of concurrent HS-SCCH and the HS-SICH formation HS-SCCH that distributes to UE.
(1) when these concurrent HS-SCCH are positioned at same time slot, the DLPC method of these HS-SCCH is as follows:
UE receives each HS-SCCH be positioned at same time slot, generates the DLPC order of a unique HS-SCCH according to the mean value of the SNR of these HS-SCCH.The unique HS-SICH that distributes to UE carries the DLPC order of the HS-SCCH of the up-to-date generation of UE.This ULPC order is carried to NODEB by the TPC territory of HS-SICH.
NODEB obtains the estimation that HS-SICH goes up TPC symbol in the TPC territory, and carries out QPSK and separate the mediation hard decision by receiving HS-SICH, obtains the DLCP order of HS-SCCH.Distribute to the DLPC order of each concurrent HS-SCCH response of UE from the HS-SCCH of the HS-SICH extraction of UE.
(2) when these concurrent HS-SCCH are positioned at different time-gap, the DLPC method of these HS-SCCH is as follows:
UE is for generating unique DLPC order at each HS-SCCH of same descending time slot, this DLPC order feeds back to NODEB by the HS-SICH with these HS-SCCH pairings.NODEB receives these HS-SICH, merges the order that these HS-SICH go up TPC, is positioned at the DLPC order of each HS-SCCH response merging of same time slot.
(3) when but these concurrent HS-SCCH were positioned at different time-gap are positioned at same time slot with the HS-SICH of these HS-SICH pairing, the DLPC method of these HS-SCCH was as follows:
UE is for generating unique DLPC order at each HS-SCCH of same descending time slot, the DLPC order of the HS-SCCH of each time slot feeds back to NODEB by the TPC territory of the HS-SICH of unique selection.This TPC carries N TPC order simultaneously, and here, N represents that concurrent HS-SCCH is positioned at N time slot.NODEB receives HS-SICH, extracts the TPC order of the HS-SCCH of each time slot from the TPC territory, is positioned at the DLPC order of each HS-SCCH response of same time slot from the HS-SCCH of this time slot of HS-SICH extraction.
The DLBF method of HS-SCCH is: the channel estimating of the HS-SICH of the UE that the NODEB basis receives is or/and the channel estimating of other down channels of UE generates the DLBF weight vector of UE.Each the concurrent HS-SCCH that distributes to UE will adopt the DLBF weight vector of the up-to-date generation of NODEB UE to carry out down beam shaping.The wave beam forming weight vector of the HS-SCCH that each is concurrent is identical.
Embodiment four proposes ULPC method and the ULSC method of a kind of HS-SICH
When adopting HS-SCCH and forwarding method to realize non-rectangle HS-PDSCH resource allocation, when each concurrent HS-SCCH was positioned at different time-gap, the HS-SICH of each HS-SCCH and pairing constituted ULPC loop and the ULSC loop of HS-SICH:
(1) the ULPC loop of HS-SICH: NODEB receives each HS-SICH that UE sends, for the HS-SICH that is positioned at same ascending time slot, NODEB will generate the ULPC order of a unique HS-SICH according to the SNR desired value of the average SNR of these HS-SICH and HS-SICH; Be used to carry the ULPC order of this ascending time slot HS-SICH of the up-to-date generation of NODEB with TPC territory on the HS-SCCH of the HS-SICH pairing that is positioned at same ascending time slot; UE receives NODEB and sends to its each HS-SCCH, for with the HS-SCCH that is positioned at same ascending time slot HS-SICH pairing, UE goes up the identical HS-SICH of TPC territory carrying to these HS-SCCH ULPC order merges, and adjusts the transmitting power of each HS-SICH that is positioned at same ascending time slot that distributes to it according to the ULPC order of this merging.
(2) the ULSC loop of HS-SICH: NODEB is when receiving each HS-SICH of UE transmission, for each HS-SICH, NODEB will be according to the channel estimating of these HS-SICH, or according to the channel estimating of other down channels of the channel estimating of these HS-SICH and UE, the ULSC (down-going synchronous control) that generates UE orders; Be used to carry the ULSC order of the UE of the up-to-date generation of NODEB with SS (simultaneous bias) territory on the HS-SCCH of these HS-SICH pairing, these HS-SCCH carry identical ULSC order; UE receives NODEB and distributes to its each HS-SCCH, merges the ULSC order that each HS-SCCH goes up the UE of SS territory carrying, adjusts the TA (Timing Advance) of the HS-PDSCH of UE according to the ULSC order that merges.Perhaps, UE goes up SS territory carrying on other down channels of UE in the ULSC order of UE of SS territory carrying and the same subframe to HS-SCCH ULSC order merges, and UE is according to the TA of each down channel of the ULSC order adjustment UE that merges.
