Description
Technical field
The present invention relates to wireless communication system, refer more particularly to a kind of transmission method and terminal of hybrid automatic retransmission request information when in multi-carrier wireless system, using multi-input/output antenna and carrying out transfer of data.
Background technology
It is a kind of technology that third generation partner program (3GPP) proposes in version 5 (Release-5) that high-speed downlink packet inserts (HSDPA), be used to improve the network data throughput of down direction (network is to terminal), the descending peak rate of its design can reach 14.4Mbps.
On physical layer design, HSDPA uses high speed down sharing physical channel (HS-PDSCH), the data that are used to carry high-speed downlink shared transmission channel (HS-DSCH) at down direction; Simultaneously, also use High-Speed Shared Control Channel (HS-SCCH) at down direction, before sending, corresponding HS-PDSCH sends, be used to notify some necessary informations of the HS-PDSCH that terminal (UE) sends after HS-SCCH, comprise employed spreading code, modulator approach, transmission block size, mix automatic repeat requests (HARQ) process, redundancy versions, new data indication, UE sign, thereby the UE by the appointment of UE sign can correctly receive the data that sent, and other UE then can't correctly receive this data.At up direction, HSDPA uses the special-purpose control physical channel (HS-DPCCH) of of HS-DSCH, by this control channel, whether UE correctly receives a transmission block among the HS-DSCH to network-feedback, ACK is for correctly receiving, NACK is not for correctly receiving, and corresponding data need to retransmit, and network retransmits or send new data in view of the above.Simultaneously, UE also feeds back a channel quality indication (CQI).The CQI table is predefined, and each CQI value is corresponding to the HS-DSCH subframe of a fixed transport block size, HS-PDSCH number, modulator approach.UE should feed back the CQI of a maximum, if represent that the HS-DSCH subframe of this CQI correspondence begins to transmit preceding 1 time slot in the HS-DPCCH subframe of carrying CQI and received by this UE, so, the error probability of corresponding transmission block is no more than 10%, with this reference as this UE quality of wireless channel.
In the design of HS-DPCCH, there are 10 bit data to be used to carry HARQ-ACK/NACK information, there are 20 to be used to carry CQI information in addition.Each UE belongs to certain specific classification (UE Category) according to the ability difference, and totally 31 in its corresponding CQI table can be represented with 5 bit data, is encoded into 20, is mapped to the CQI bit field of HS-DPCCH.There are two kinds of situations of ACK/NACK in HARQ, and expression correctly receives data block and there is mistake in the data block that receives respectively, and is encoded into 10 by specific code book, is mapped to the HARQ-ACK bit field of HS-DPCCH.
Fig. 1 is the FEEDBACK CONTROL channel HS-DPCCH schematic diagram of available technology adopting.Each HS-DPCCH subframe is 2ms, takies 3 time slots.First time slot in each HS-DPCCH subframe is used to carry HARQ-ACK information, can carry 10 bit data altogether.Thereafter 2 time slots are used to carry CQI/PCI information, can carry 20 bit data altogether.
Subsequently, on the basis of HSDPA, 3GPP strengthens from many aspects.Multiple-input and multiple-output (MIMO) antenna technology is wherein a kind of method that improves the wireless channel transmission bandwidth.3GPP has adopted the MIMO technology at Rel-7, allows to transmit simultaneously maximum two transmission blocks (main transmission block and auxilliary transmission block) and give same UE in a 2ms TTI.For supporting the MIMO technology, transmitting terminal need modulate data on two incoherent antennas and send simultaneously, and the recipient also needs to receive data simultaneously from two incoherent antennas, and carries out demodulation.Identical with HSDPA is that UE needs feedback HARQ-ACK and CQI equally after receiving the HS-DSCH data.Different is, UE need feed back HARQ-ACK respectively to two HS-DSCH transmission blocks that receive simultaneously, and CQI also at two empty channels that divide, is designated as CQI
1And CQI
2In addition, UE also needs the required aerial array weights of feedback closed loop MIMO, and promptly the precoding weights maximize so that transmission block is big or small.The precoding weights have four: w
1, w
2, w
3And w
4, (w
1, w
2) form main precoding vector, the data of main transmission block are weighted; (w
3, w
4) then form auxilliary precoding vector, the data of assisting transmission block are weighted.Main precoding vector is used to transmit main transmission block, and auxilliary precoding vector is used to transmit auxilliary transmission block.In four precoding weights, w
1And w
3Be fixed value, w
2And w
4Have the mark-hold relation, so UE only need feed back the precoding weight w
2, this realizes by precoding control indication (PCI).w
2In desirable 4 values one is so PCI is 2 bit data.Under the MIMO situation, use new CQI table, the CQI table of the UE classification correspondence that each is specific is 15, represents CQI with 4 bit data
1/ CQI
2Need 8 altogether.Like this, it is 10 bit data that PCI/CQI combines, and is encoded into 20, is mapped to the CQI/PCI bit field (being original C QI bit field) of HS-DPCCH.HARQ need consider the six kinds of situation combinations of ACK/NACK under single current and the double-current situation, is encoded into 10 by specific code book, is mapped to the HARQ-ACK bit field of HS-DPCCH.
Above said MIMO technology improve bandwidth by increasing number of antennas simultaneously transmit leg and recipient.If do not adopt the MIMO technology, also can adopt the method that increases carrier wave to improve bandwidth.In order further to improve downlink bandwidth, 3GPP has introduced dual carrier HSDPA technology (DC-HSDPA) at Rel-8, utilizes two adjacent carriers (main carrier and auxilliary carrier wave) to improve downlink bandwidth.Main carrier and auxilliary carrier wave are provided with HS-PDSCH and HS-SCCH respectively simultaneously, and independently dispatch.For having the UE that receives the DC-HSDPA ability, can receive the HSDPA data at main carrier and auxilliary carrier wave simultaneously.Identical with single carrier HSDPA is that UE needs feedback HARQ-ACK and CQI equally after receiving the HS-DSCH data; Different is, UE need feed back HARQ-ACK respectively to two HS-DSCH transmission blocks that receive simultaneously on two carrier waves, and CQI also at two carrier waves, is designated as CQI

2Totally 10 bit data are encoded into 20 bit data, are mapped to the CQI bit field of HS-DPCCH.HARQ need consider the eight kinds of situation combinations of ACK/NACK under single carrier and the multicarrier situation, is encoded into 10 by specific code book, is mapped to the HARQ-ACK bit field of HS-DPCCH.
In order further to improve downlink bandwidth, 3GPP makes up DC-HSDPA and MIMO in Rel-9.In the HS-DPCCH design, take all factors into consideration from performance and power consumption, still adopt a HS-DPCCH channel to be used for feedback information.HARQ need consider the 48 kinds of situation combinations of ACK/NACK under main carrier and auxilliary carrier wave, single current and the multithread situation, is encoded into 10 by specific code book, is mapped to the HARQ-ACK bit field of HS-DPCCH.PCI need feed back respectively main carrier and auxilliary carrier wave, is designated as PCI

2, be 8 bit data, main carrier and auxilliary carrier wave are 16 bit data altogether.In other words, the CQI/PCI of main carrier is 10 bit data, and the CQI/PCI of auxilliary carrier wave also is 10 bit data.In the HS-DPCCH transmission, the CQI/PCI of main carrier is totally 10 bit data, is encoded into 20, is mapped to the CQI/PCI bit field of one of them subframe in continuous two subframes of HS-DPCCH; The CQI/PCI of auxilliary carrier wave is totally 10 bit data, is encoded into 20, is mapped to the CQI/PCI bit field of the another one subframe in continuous two subframes of HS-DPCCH.That is to say that the CQI/PCI data of main carrier and auxilliary carrier wave are transmitted on HS-DPCCH by time-multiplexed mode.
Fig. 2 is two carrier wave MIMO feedback information schematic diagrames of available technology adopting.In recipient's transmission main carrier,, comprise, mix automatic repeat requests (HARQ), channel quality indication (CQI) and precoding control indication (PCI) with the two required feedback informations of carrier wave MIMO of control channel HS-DPCCH feedback.MIMO single current or double-current HARQ information are encoded into 10 bit data by specific code book on two carrier waves, transmit at the HARQ of each HS-DPCCH subframe bit field.The PCI of main carrier and CQI totally 10 bit data are encoded into 20 bit data, the CQI/PCI bit field transmission of one of them subframe in continuous two subframes of HS-DPCCH.And the PCI of auxilliary carrier wave and CQI totally 10 bit data also be encoded into 20 bit data, the CQI/PCI bit field transmission of the another one subframe in continuous two subframes of HS-DPCCH.
Fig. 3 is the different situations and the coding schematic diagram of dual carrier HSDPA combination mimo system hybrid automatic retransmission request information in the prior art.In a carrier wave that disposes MIMO, there are following these situations in the data that transmit leg sends: single current sends, double fluid sends, do not send data.Accordingly, the recipient has two kinds of situations after receiving the packet that single current sends: correct reception, mistake receive.For the packets need that correctly receives to transmit leg feeding back ACK (writing a Chinese character in simplified form into A under the situation about not leading to misunderstanding), and the packets need that receives for mistake feedback NACK (writing a Chinese character in simplified form into N under the situation about not leading to misunderstanding).The recipient is behind the packet that receives the double fluid transmission, situation is just more complicated, situation about existing is: correctly receive mainstream data+correct and receive auxilliary flow data, correctly receive mainstream data+mistake and receive auxilliary flow data, mistake and receive that mainstream data+correct receives auxilliary flow data, mistake receives mainstream data+mistake and receives auxilliary flow data, accordingly, the recipient needs respectively to transmit leg feedback AA, AN, NA, NN.In addition, the recipient may not receive any data at this carrier wave, such as, but do not sent the data recipient and missed though transmit leg sends data or transmit leg, in this case, the recipient need feed back DTX (discontinuous transmission, write a Chinese character in simplified form into D under the situation about not leading to misunderstanding), certainly, if single carrier case or other carrier waves all are DTX, then do not need to feed back DTX.Therefore, under the situation of multi-carrier HSDPA combination MIMO, the recipient is A/N/AA/AN/NA/NN/D totally seven kinds of situations for the situation of the informational needs feedback of one of them carrier wave, two carrier waves then are the various combinations of these seven kinds of situations, need to consider 7 * 7=49 kind situation altogether, removing does not wherein need the D/D situation fed back, need be 48 different codings of hybrid automatic retransmission request information Combination Design.Such as, AN/NA, mainstream data correctly receives, assists the reception of flow data mistake on the expression main carrier, and mainstream data mistake reception on the auxilliary carrier wave, auxilliary flow data correctly receive; D/AN does not receive data on the expression main carrier, and mainstream data correctly receives, assists the reception of flow data mistake on the auxilliary carrier wave.
In order further to improve user's peak rate, more carrier combination need be transmitted together, such as on the bandwidth of 20MHz, carrying out the MIMO transfer of data, just need will reach four carrier combination together, can both support HSDPA and MIMO on each carrier wave.The HARQ information that each carrier wave need feed back is among the A/N/D/AA/AN/NA/NN, totally seven kinds of situations.According to existing HARQ feedback information transmission method, the combined number that needs under four carrier case to consider is 7 * 7 * 7 * 7-1=2400.Because the data field of carrying HARQ feedback information is 10, can feed back 1024 kinds of situations at most, the feedback requirements of HARQ information head and shoulders above the bearing capacity in 10 bit data territories.Therefore, need a kind of new HARQ information transferring method, can satisfy under the four carrier HSDPAs combination MIMO situation requirement of HARQ transmission of Information.
Fig. 4 is according to prior art, and the combination of four carrier HSDPAs combination mimo system hybrid automatic retransmission request information needs the different situations schematic diagram of consideration.According to prior art, the recipient is in seven kinds of situations of A/N/AA/AN/NA/NN/D any one for the hybrid automatic retransmission request information of the informational needs of one of them carrier wave feedback, four carrier waves then are the various combinations of these seven kinds of situations, need to consider 7 * 7 * 7 * 7=2401 kind situation altogether, remove and wherein do not need the D/D/D/D situation fed back, need be 2400 different codings of hybrid automatic retransmission request information Combination Design, hybrid automatic retransmission request information coding of each numeral among the figure, the coding that different numerals is different.Because the data field at a HS-DPCCH channel bearing HARQ feedback information is 10, can feed back 1024 kinds of situations at most, HARQ feedback information demand has exceeded the bearing capacity in 10 bit data territories.Therefore, be to finish the coding of four carrier HSDPAs combination mimo system hybrid automatic retransmission request information combination all situations according to prior art.
