Description
Technical field
The present invention relates to 3G (Third Generation) Moblie technical field, particularly high-speed physical downlink shared channel (HS-PDSCH) (HS-PDSCH) resource allocation methods and the device in a kind of high-speed downstream bag access (HSDPA).
Background technology
In prior art, on HSDPA carrier wave, the HSDPA scheduler of base station (NODEB) is once dispatched in each subframe.Scheduler is determined the UE being scheduled in current subframe, and is each UE distribution 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 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 and the HS-SICH that distributes to the HS-SCCH pairing of UE; The HS-PDSCH that distributes to UE is a part of resource in HS-PDSCH resource pool or whole resources, and the shared resource of HS-PDSCH of distributing to UE must be rectangle resource.So-called rectangle resource refers to, 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, take time slot on the channel resource chart that abscissa, channel code are ordinate, the shape that the resource that HS-PDSCH takies forms must be rectangle.
In prior art, HS-PDSCH resource allocation flow as shown in Figure 1, comprises the steps:
Step 101:RNC gives each HSDPA carrier wave configuration some to HS-SCCH and HS-SICH, and notifies NODEB by configuration information.
Step 102: to each HSUPA UE, on the HSUPA at this UE place carrier wave, NODEB selects several HS-SCCH as the HS-SCCH set of described UE from the HS-SCCH of this carrier wave of RNC configuration.Correspondingly, to the HS-SICH of the HS-SCCH pairing in the HS-SCCH set of UE, form the HS-SICH set of UE with configuration.
Step 103:NODEB is by the configuration information notice RNC of the HS-SCCH set of UE and HS-SICH set; By RNC, this configuration information is transmitted to UE.If in the number of HS-SCCH and the HS-SICH of UE set, the number of HS-SICH is K in the HS-SCCH of UE set
pair, K
pairmaximum be K
pair=4.
Step 104:NODEB carries out a HSDPA scheduling at each subframe n.By dispatching, determine each UE being scheduled in current subframe, and be each UE distribution HS-SCCH, HS-PDSCH and HS-SICH being scheduled.
Step 105: the UE that each is scheduled, NODEB sends to UE by the HS-SCCH that distributes to this UE; To distribute the HS-PDSCH of this UE to send to UE; And receive the HS-SICH of UE feedback.This step detailed process is as follows:
Step 105-1:NODEB (n+d) subframe by distribute to UE HS-PDSCH resource configuration information and for HS-PDSCH resource on the information exchange over-allocation of high speed descending sharing channel (HS-DSCH) the data block decoding of carrying to the HS-SCCH of UE, send to UE.Here, d represents the processing delay of the scheduler of NODEB.
Step 105-2: when UE is when (n+d) subframe detects NODEB and sends to its HS-SCCH, UE determines the HS-PDSCH that distributes to it according to the configuration information of the HS-PDSCH resource of carrying on HS-SCCH, according to the information for the decoding of HS-DSCH data block of carrying on HS-SCCH, determine the required parameters of HS-DSCH data block decoding.UE is also using the HS-SICH of the HS-SCCH pairing with detecting as distributing to its HS-SICH.
Step 105-3:NODEB is according to a HS-DSCH data block of HS-PDSCH resource assembling of distributing to UE.NODEB sends to UE in n+d+d1 subframe by the HS-PDSCH that distributes to UE.Here, d1=1 represents the timing difference between the subframe of HS-SCCH transmission and the subframe of HS-PDSCH transmission.
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 confirmation (ACK) information; Otherwise, will generate non-confirmation (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.
In (n+d+d1+d2) subframe, the HS-SICH by distributing to it sends to NODEB by the ACK information of the CQI information of the HS-PDSCH of up-to-date generation and HS-DSCH data block (to HS-DSCH data block correct decoding time) or nack message (to the decoding of HS-DSCH data block error time) to step 105-5:UE.Here, d2=2 represents the timing difference between the subframe of HS-PDSCH transmission and the subframe of HS-SICH transmission.
Step 105-6:NODEB receives the HS-SICH that distributes to UE in (n+d+d1+d2) subframe.When NODEB is 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, 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 n sub-frame allocation, NODEB is when n+1 subframe is dispatched this UE again, and it must be the 1st HS-SCCH that NODEB distributes the HS-SCCH of this UE.
For UE, UE distributes to monitoring in first subframe each HS-SCCH in its HS-SCCH set.When UE listens to 1 this HS-SCCH of HS-SCCH(that distributes to it in previous subframe, be called a HS-SCCH) time, UE will only monitor a HS-SCCH in current subframe.When UE is not when previous subframe listens to the HS-SCCH that distributes to it, UE is by each HS-SCCH monitoring in current subframe in the HS-SCCH set of distributing to it.Above-mentioned UE shows the snoop procedure of HS-SCCH set: in prior art, UE does not support NODEB, in same subframe, a plurality of HS-SCCH are distributed to described UE.
In the send and receive process of above-mentioned HS-SCCH, HS-PDSCH and HS-SICH, also there is the process of synchronously carrying out as follows:
1, HS-SCCH and HS-SICH form downlink power control (DLPC) loop of HS-SCCH:
UE generates the DLPC order of HS-SCCH according to the signal to noise ratio (snr) of the HS-SCCH that distributes to it receiving and the SNR desired value of HS-SCCH; The transmitting power of distributing on the HS-SICH of UE is controlled (TPC) territory for carrying the DLPC order of the HS-SCCH of the up-to-date generation of UE; NODEB receives the HS-SICH that UE sends, and extracts the DLPC order of the HS-SCCH of the upper TPC of HS-SICH territory carrying, distributes to the transmitting power of the HS-SCCH of UE according to this DLPC order adjustment.
2, HS-SCCH and HS-SICH form uplink power control (ULPC) loop of HS-SICH:
NODEB, when receiving the HS-SICH of UE, will generate the ULPC order of HS-SICH according to the SNR desired value of the SNR of HS-SICH and HS-SICH; Distribute to TPC territory on the HS-SCCH of UE for carrying the ULPC order of HS-SICH of the UE of the up-to-date generation of NODEB; UE receives the HS-SCCH that NODEB sends to it, extracts the ULPC order of the HS-SICH of the upper TPC of HS-SCCH territory carrying, distributes to the transmitting power of its HS-SICH according to this ULPC order adjustment.
3, HS-SCCH and HS-SICH form uplink synchronous control (ULSC) loop of HS-SICH:
NODEB, when receiving the HS-SICH that UE sends, by according to the channel estimating of HS-SICH, 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 simultaneous bias (SS) territory on the HS-SCCH of UE for carrying the ULSC order of the UE of the up-to-date generation of NODEB; UE receives the HS-SCCH that NODEB distributes to it, extracts the ULSC order of the UE of the upper SS of HS-SCCH territory carrying, adjusts the Timing Advance (TA) of the HS-SICH of UE according to this ULSC order.Or UE merges the ULSC order of SS territory carrying on other down channels of UE in the ULSC order of the UE of the upper SS of HS-SCCH territory carrying and same subframe, UE adjusts the TA of each up channel of UE according to the ULSC order merging.
4, the down beam shaping of HS-SCCH (DLBF):
The channel estimating of the HS-SICH of the UE that NODEB receives basis is 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 HSDPA system, conventionally adopt the Typical Disposition of 2:4 or 3:3.Under the Typical Disposition of 2:4, the HS-PDSCH resource pool that RNC distributes to NODEB takies 4.5 time slots conventionally.Under the Typical Disposition of 3:3, the HS-PDSCH resource pool that RNC distributes to NODEB takies 3.5 time slots conventionally.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 at most 4 time slots (during 2:4 configuration) or 3 time slots (during 3:3 configuration), the resource of 4.5 time slots (during 2:4 configuration) in resource pool or 3.5 time slots (during 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 2Mbps or 3 1.5Mbps that time slot can be supported that 4 time slots (during 2:4 configuration) can be supported, can not reach the 1.75Mbps that 2.2Mbps that 4.5 time slots (when 2:4 configures) can support or 3.5 time slots (when 3:3 configures) can be supported.

In view of the HS-PDSCH resource distribution mode of rectangle has greatly limited the descending peak rate of UE, the present invention proposes: for improving the descending peak rate of UE, can distribute the HS-PDSCH resource of 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 3:3 configuration, 3.5 time slots of HS-PDSCH resource pool all can be distributed to UE.
For realizing the HS-PDSCH resource of distributing non-rectangle to UE, need to the non-rectangle HS-PDSCH resource notification UE of UE will be distributed to.The present invention proposes to distribute to the method for the non-rectangle resource notification UE of UE, and the method comprises following content:
1, by the non-rectangle HS-PDSCH resource of distributing to UE, by HS-SCCH, notify the method to UE;
2, UE obtains the method for the non-rectangle HS-PDSCH resource of distributing to it by HS-SCCH;
3, for distributing 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 ACK/NACK information of feedback non-rectangle HS-PDSCH resource and the HS-SICH of CQI information.
Below by specific embodiment, above-mentioned every method is set forth respectively respectively.
What the embodiment of the present invention one proposed notifies by HS-SCCH the non-rectangle HS-PDSCH resource of distributing to UE to the method for UE as shown in Figure 2, comprises the steps:
Step 201:RNC is divided into 2 rectangle HS-PDSCH child resource ponds by the HS-PDSCH resource pool of distributing to the carrier wave of NODEB, and notifies described NODEB by these two shared time slots in rectangle HS-PDSCH child resource pond;
Step 202: when described UE is linked into the described carrier wave under described NodeB, RNC is by the shared time slot notice UE in two rectangle HS-PDSCH child resource ponds of described carrier wave;
Step 203: when described UE is scheduled, described NODEB selects the first rectangle resource from the first rectangle HS-PDSCH child resource pond, selects the second rectangle resource from the second rectangle HS-PDSCH child resource pond;
Step 204: described NODEB determines the HS-SCCH form with described UE state matches according to the current residing state of UE, in this HS-SCCH form, carry gap information and the channel code information of described the first rectangle resource and the second rectangle resource, and to UE, send the HS-SCCH of described HS-SCCH form.
For making the distribution method backward compatibility of non-rectangle HS-PDSCH resource of the present invention, for the UE that supports that non-rectangle HS-PDSCH resource is distributed, UE need to report the first Indication message to RNC, and described the first Indication message has for showing this UE the ability of supporting that non-rectangle HS-PDSCH resource is distributed.For the NODEB that supports that non-rectangle HS-PDSCH resource is distributed, NODEB need to report the second Indication message to RNC, and described the second Indication message has for showing this NODEB the ability of supporting that non-rectangle HS-PDSCH resource is distributed.
For the NODEB that supports that non-rectangle HS-PDSCH resource is distributed, HS-PDSCH resource pool on any one carrier wave that RNC could support this NODEB is divided into two sub-resource pools and configures to NODEB, meanwhile, the ability that RNC need to distribute the support non-rectangle HS-PDSCH resource of UE is transmitted to the NODEB that supports that non-rectangle HS-PDSCH resource is distributed.RNC also needs to configure two sub-resource pools on this UE place carrier wave to the UE that supports non-rectangle HS-PDSCH resource to distribute.
For the NODEB that supports that non-rectangle HS-PDSCH resource is distributed, NODEB need to give the UE distribution non-rectangle resource of supporting the distribution of non-rectangle HS-PDSCH resource on this carrier wave by two sub-resource pools based on each carrier wave.
