m＝(T TX_diff/256)+101，
In the following formula, T TX_diffFor HS-PDSCH subframe starting point with comprise the descending DPCH of HS-PDSCH subframe starting point or the time chip deviate of F-DPCH radio frames starting point.The span of m value is the integer between [0,250].
Because the down channel that the major-minor Serving cell of different sectors sends in the multithread transmission system exists the airborne spread time delay of vertical shift and each sector inconsistent, causes UE to receive respectively the Time Inconsistency of HS-PDSCH channel from the major-minor Serving cell of different sectors.But, the regulation of pressing existing protocol, UE can't send at synchronization HARQ feedback and the CQI indication of combined coding to the inconsistent major-minor Serving cell of vertical shift.For so that UE sends HARQ feedback and CQI indication can be simultaneously for the major-minor Serving cell of multithread transmission system, present 3GPP is studying following solution:
Frame according to the major-minor Serving cell at subscriber equipment place regularly matches to high-speed physical downlink shared channel (HS-PDSCH) (HS-PDSCH) subframe of major-minor Serving cell, wherein, the HS-PDSCH subframe of major-minor Serving cell of pairing need meet the following conditions: the time difference of establishing between time of HS-PDSCH subframe of arbitrary auxiliary serving cell of time of HS-PDSCH subframe of the main Serving cell that subscriber equipment receives and the pairing of receiving is Δ T, then Δ T is more than or equal to the minimum time deviation and less than or equal to the maximum time deviation, the minimum time deviation comprises 0, maximum time deviation comprise 3 time slots (7680 chip).
After the pairing of the HS-PDSCH of major-minor Serving cell subframe is finished, subscriber equipment take the frame of main Serving cell regularly as benchmark, according to the HS-DPCCH subframe of existing protocol 25.211 regulations and the time relationship of UL-DPCCH or HS-PDSCH, the HS-PDSCH subframe of the major-minor Serving cell of pairing is sent simultaneously HARQ feedback and/or the CQI indication of combined coding at HS-DPCCH subframe head corresponding to main Serving cell.

For guaranteeing that auxiliary serving cell can obtain the accurately result of the HS-PDSCH subframe pairing of major-minor Serving cell in real time, to receive exactly the HS-DPCCH subframe, and definite HS-PDSCH subframe corresponding with the HS-DPCCH subframe that receives, in this preferred embodiment, when the HS-PDSCH of major-minor Serving cell subframe pairing changes, the HS-PDSCH subframe pairing result of the major-minor Serving cell after upgrading is reported the base station corresponding with each auxiliary serving cell.
In above preferred embodiment, when the pairing of the HS-PDSCH of major-minor Serving cell subframe changes, the result of the HS-PDSCH subframe pairing of the major-minor Serving cell that will upgrade has in time reported the base station corresponding with each auxiliary serving cell, namely after for the first time the HS-PDSCH subframe of major-minor Serving cell being matched, when the pairing of the HS-PDSCH of major-minor Serving cell subframe changes, the HS-PDSCH subframe pairing result of the major-minor Serving cell after can will upgrading in real time reports the base station corresponding with each auxiliary serving cell, can obtain in real time the accurately result of the HS-PDSCH subframe pairing of major-minor Serving cell with the assurance auxiliary serving cell, thereby decipher exactly the HS-DPCCH subframe.
Below in conjunction with example above-mentioned each preferred embodiment is described in detail.
In the multithread transmission system, can regularly the HS-PDSCH subframe of major-minor Serving cell be matched according to the frame of the major-minor Serving cell at subscriber equipment place, and the result that will match reports serving BS corresponding to auxiliary serving cell, and the HS-PDSCH subframe pairing result of major-minor Serving cell comprises that the HS-PDSCH subframe 0 of indicate main Serving cell and which HS-PDSCH subframe of auxiliary serving cell match; The m value that at least one HS-PDSCH subframe of main Serving cell is corresponding reports serving BS corresponding to auxiliary serving cell simultaneously, report base station corresponding to auxiliary serving cell such as the m value with HS-PDSCH subframe 0 correspondence of main Serving cell, according to prior art as shown in Figure 1, the m value is to characterize the starting point of HS-DPCCH subframe corresponding to some HS-PDSCH subframes and the time difference of UL-DPCH channel wireless frame starting point, unit is 256 chips, span is 0～250 integer, if take 1 chip as unit reports the described time difference also passable, this moment, span was 0～64000 integer, to take chip as unit or At All Other Times granularity equally applicable the present invention of described time difference as unit reports, for convenience of description, the present invention unifies to be described take 256 chips as unit.Afterwards, the HARQ of the major-minor Serving cell HS-PDSCH subframe that can will match on HS-DPCCH subframe corresponding to main Serving cell of subscriber equipment and/or the CQI of all Serving cells feed back to serving BS corresponding to major-minor Serving cell.
The HARQ feedback of wherein, the major-minor Serving cell HS-PDSCH subframe of pairing being carried out adopts the combined coding mode.And carry out HS-DPCCH subframe when pairing, in can the HS-PDSCH subframe with the HS-PDSCH subframe of main Serving cell and auxiliary serving cell, the subframe poor Δ T time of advent (time that the HS-PDSCH subframe of main Serving cell arrives deducts the time that the HS-PDSCH subframe of auxiliary serving cell arrives) satisfies the HS-PDSCH subframe pairing of setting-up time scope.That is to say, the Δ T of the HS-PDSCH subframe of the major-minor Serving cell of pairing is more than or equal to the minimum time deviate and less than or equal to the maximum time deviate.
Particularly, UE sends the method for HS-DPCCH in a kind of multithread transmission system that the present embodiment provides, and as shown in Figure 4, comprises following steps:
Step S402:UE activates the multithread transfer function;
The HARQ process number that step S404:RNC configures this UE master's Serving cell and auxiliary serving cell all is 7;
Need to prove, when the HARQ process of the major-minor Serving cell of configuration UE is counted, be not limited to 7, can be according to practical application scene arbitrary disposition.
Step S406:UE measures the frame timing of major-minor Serving cell, regularly the HS-PDSCH subframe of major-minor Serving cell is matched according to measured frame, and the HS-PDSCH subframe of the major-minor Serving cell that will match pairing result reports base station corresponding to auxiliary serving cell, and the m value that one or more HS-PDSCH subframes of main Serving cell are corresponding reports base station corresponding to each auxiliary serving cell simultaneously;
In this step, UE measures the frame timing of major-minor Serving cell, calculate the frame timing slip of major-minor Serving cell, according to the frame timing slip of major-minor Serving cell the major-minor Serving cell HS-PDSCH subframe poor Δ T time of advent is satisfied again the HS-PDSCH subframe pairing of setting-up time scope, wherein, the setting-up time value range is more than or equal to the minimum time deviate and less than or equal to the maximum time deviate.The minimum time deviate and maximum time deviate can be according to the practical situations concrete configuration, and preferential in the present embodiment to recommend the minimum time deviate be 0, maximum time deviate be 2 milliseconds.
Notify the m value of HS-PDSCH subframe 0 correspondence of the first-selected main Serving cell of m value of each auxiliary serving cell respective base station (to be designated as
Figure BDA0000144378180000101
), the m value m that the HS-PDSCH subframe i (i=0,1,2,3,4) of auxiliary serving cell is corresponding iCan calculate according to following formula,
m i = [ m 0 P - 101 + 30 · ( i - n pairedSF + 5 ) % 5 ] % 150 + 101
Wherein, n PairedSFThe HS-PDSCH subframe numbers with the auxiliary serving cell of HS-PDSCH subframe 0 pairing of main Serving cell, n PairedSFThe result obtains according to pairing.
In addition, in other scenes, the operation of step S406 also is not limited to UE.That is to say, except UE, also can by network equipment, such as radio network controller (RNC) the HS-PDSCH subframe of main Serving cell be matched.At this moment, UE measures the frame timing of major-minor Serving cell, calculate the frame timing slip of major-minor Serving cell and report RNC, RNC matches to the HS-PDSCH subframe of major-minor Serving cell according to the frame timing slip of major-minor Serving cell, and will match that the result reports UE and base station corresponding to auxiliary serving cell gets final product.
Step S408: serving BS is selected available this UE of HARQ process scheduling;
Step S410:UE take main Serving cell HS-DPCCH subframe time of existing 3GPP 25.211 protocol definitions as benchmark, major-minor Serving cell to pairing on HS-DPCCH subframe corresponding to main Serving cell carries out the HARQ feedback, and/or all Serving cells are carried out the CQI feedback.Wherein, the HS-PDSCH subframe of the pairing HARQ feedback of carrying out adopts the combined coding mode.
The above-mentioned mixed automatic retransfer request feedback that the HS-PDSCH subframe of pairing is carried out adopts the combined coding mode to refer to: HARQ corresponding to each subframe in the HS-PDSCH subframe of the major-minor Serving cell of pairing carried out combined coding.
After the operation of above-mentioned steps S410, also comprise the operation of the serving BS that each Serving cell is corresponding.M value in the UL-DPCCH radio frames starting point that method calculating when the serving BS that wherein main Serving cell is corresponding can transmit by existing non-multithread receives and the timing relationship of HS-DPCCH subframe starting point.And for serving BS corresponding to auxiliary serving cell, m value corresponding to the value of the m value in the UL-DPCCH radio frames starting point that it receives and the timing relationship of HS-DPCCH subframe starting point and the HS-DPCCH subframe of the main Serving cell of this HS-DPCCH subframe pairing is the same.
Also have some schemes to consider, in the data transmission procedure, in the HS-PDSCH subframe of the major-minor Serving cell of pairing, the subframe poor Δ T time of advent can change, and may exceed the setting-up time scope, needs to upgrade pairing this moment.And the subframe poor Δ T time of advent between the major-minor Serving cell HS-PDSCH subframe after the assurance renewal pairing satisfies the setting-up time scope.Particularly, this upgrades and operates and can be finished by subscriber equipment or network equipment (such as RNC).For example, subscriber equipment is measured the frame timing of major-minor Serving cell in real time, regularly calculate the frame timing slip of major-minor Serving cell according to the frame that measures in real time, when determining subframe between arbitrary auxiliary serving cell HS-PDSCH subframe of main Serving cell HS-PDSCH subframe and its pairing the time of advent, poor Δ T exceeding described setting-up time scope, upgrade major-minor Serving cell HS-PDSCH subframe pairing.And for example, subscriber equipment regularly calculates the frame timing slip of major-minor Serving cell and reports radio network controller according to the frame that measures in real time, when radio network controller is determined subframe between arbitrary auxiliary serving cell HS-PDSCH subframe of main Serving cell HS-PDSCH subframe and its pairing the time of advent, poor Δ T was exceeded described setting-up time scope, upgrade major-minor Serving cell HS-PDSCH subframe pairing, the pairing result after upgrading is reported described subscriber equipment.
Other schemes also propose, base station corresponding to auxiliary serving cell be according to after m value corresponding to the HS-PDSCH subframe pairing result who receives major-minor Serving cell and at least one HS-PDSCH subframe of main Serving cell, HS-PDSCH subframe corresponding to HS-DPCCH that just can determine the moment of reception HS-DPCCH and determine to receive.
Be described in further detail below in conjunction with the enforcement of accompanying drawing to such scheme:
Fig. 5 is the sequential schematic diagram that multithread transmission UE sends HS-DPCCH and serving BS decoding ACK/NACK.Need to prove, because therefore main Serving cell and auxiliary serving cell might be positioned under the same base station, also may be positioned under the different base station,, in the situation that do not specify, serving BS hereinafter is the general designation to base station under main Serving cell and the auxiliary serving cell.Suppose that UE among Fig. 5 is Δ T to the propagation delay of major-minor Serving cell; Tn1 is that main Serving cell DL-DPCH is with respect to the system-frame skew of main Serving cell; Tn2 is that auxiliary serving cell DL-DPCH is with respect to the system-frame skew of auxiliary serving cell; The m*256 chip is the timing relationship of UE emission UL-DPCCH radio frames starting point and the HS-DPCCH subframe starting point that UE launches of 3GPP 25.211 agreements regulation; And the frame boundaries of auxiliary serving cell is than Zao 2 time slots of the frame boundaries of main Serving cell.The HS-PDSCH subframe 0 of the HS-PDSCH subframe 0 of main Serving cell and auxiliary serving cell is matched in the figure, and the HS-PDSCH subframe 1 of main Serving cell and the HS-PDSCH subframe 1 of auxiliary serving cell are matched, the like.After the HS-PDSCH subframe pair relationhip of major-minor Serving cell is determined, need the HS-PDSCH subframe pairing result of main Serving cell and auxiliary serving cell is reported serving BS corresponding to auxiliary serving cell.When the vertical shift of major-minor Serving cell changes and need to upgrade the HS-PDSCH subframe pair relationhip of major-minor Serving cell, need report serving BS corresponding to auxiliary serving cell with upgrading main Serving cell after the pairing and the HS-PDSCH subframe pairing result of auxiliary serving cell pairing.
Concerning main Serving cell, the computational methods of the m value in the timing relationship of the UL-DPCCH radio frames starting point that it receives and HS-DPCCH subframe starting point are duplicate when transmitting with existing non-multithread; Concerning auxiliary serving cell, m value value corresponding to arbitrary HS-PDSCH subframe is the m value corresponding with the HS-PDSCH subframe of the main Serving cell of this HS-PDSCH subframe pairing, for example shown in Figure 5, the HS-PDSCH subframe 0 of auxiliary serving cell and 0 pairing of the HS-PDSCH subframe of main Serving cell, the m value of the HS-PDSCH subframe 0 of auxiliary serving cell is the same with the m value value of the HS-PDSCH of main Serving cell so.Auxiliary serving cell is determined m value corresponding to the arbitrary HS-PDSCH subframe of auxiliary serving cell according to the HS-PDSCH subframe numbering of major-minor Serving cell pairing and the m value corresponding to any HS-PDSCH subframe of main Serving cell, so the subframe of the HS-PDSCH that is scheduled of auxiliary serving cell basis numbers to determine that m value corresponding to this subframe just can determine to receive the moment of HS-DPCCH corresponding to this subframe.
The hypothesis serving BS adopts i HARQ process HARQi to dispatch at 0 couple of this UE of HS-PDSCH subframe at the main Serving cell of this UE among Fig. 5, adopts k HARQ process HARQk to dispatch at 0 couple of this UE of HS-PDSCH subframe in the auxiliary serving cell of this UE.UE sends moment of HS-DPCCH of combined coding take the HS-PDSCH subframe 0 receiving main Serving cell and send as benchmark among this figure, after receiving the HS-PDSCH subframe 0 that main Serving cell is sent, stipulate by existing 3GPP25.211 agreement, approximately send again the ACK/NACK that carries combined coding and the HS-DPCCH of CQI indication behind 7.5 time slots, and UE sends HS-PDSCH subframe 0 about 9.5 time slots that the moment distance of the HS-DPCCH of combined coding receives auxiliary serving cell.Main Serving cell is after receiving and deciphered the HS-DPCCH that this UE sends over, can adopt identical HARQi process that this UE is dispatched in second subframe 1 of HS-SCCH, then UE on HARQi from being scheduled for for the first time 5 subframes (being to be dispatching cycle 6 subframes) that for the second time have been scheduled the interval.Auxiliary serving cell is after receiving and deciphered the HS-DPCCH that this UE sends over, can adopt identical HARQk process that this UE is dispatched in second subframe 2 of HS-SCCH, then this UE on HARQk from being scheduled for for the first time 6 subframes (being to be dispatching cycle 7 subframes) that for the second time have been scheduled the interval.
