Description
Technical field
(be called for short, the LTE) data transmission technology of system specially refers to a kind of LTE ascending HARQ control method to the present invention relates to Long Term Evolution.
Background technology
The evolution accessing network that the general continental rise wireless access network E-UTRAN of evolution is general continental rise wireless access network UTRAN; Its access technology that adopts is called the LTE technology; Difference according to duplex mode; LTE can be divided into two kinds of systems: (be called for short, TDD-LTE) system, FDD (are called for short FDD-LTE) system to time division duplex LTE.
Mix automatically to retransmit and (be called for short; HARQ) a kind of transmission technology of technological GSM extensive use; Time-domain position according to the HARQ transmission can be divided into synchronous HARQ and asynchronous HARQ with HARQ, and the configuration of transmitting according to HARQ can be divided into adaptive HARQ and non-self-adapting HARQ with HARQ again; Ascending HARQ is the synchronous HARQ mode that self adaptation and non-self-adapting combine among the LTE, and synchronous HARQ is meant that the transmission time-domain position of each HARQ is limited on the predefined time slot position; According to the description of 3GPP TS 36.213 standards, sequential relationship is as shown in Figure 1 in the ascending HARQ transmission course: network (is called for short, DCI0) sends resource for UE distributes ascending HARQ through form 0 Downlink Control Information; Portable terminal (is called for short; UE) after receiving DCI0; (be called for short, PUSCH) carry out the ascending HARQ data and send, network (is called for short at the Physical HARQ Indicator Channel of the pairing subframe of this PUSCH at Physical Uplink Shared Channel according to the indication of DCI0; PHICH) go up to send feedback information and/or (be called for short, PDCCH) go up the DCI0 information of sending at the Physical Downlink Control Channel of the pairing subframe of this PUSCH; For a HARQ formation; When UE receives DCI0 or the PHICH feedback information indication new biography on the PDCCH or retransmits; The PUSCH that is fixed on PHICH place subframe J+K sub-frame afterwards carries out upstream data and sends; Be fixed on transmission PUSCH subframe L sub-frame afterwards and receive corresponding PHICH, be fixed on and send PUSCH subframe L+J sub-frame reception DCI0 afterwards.
Wherein, preserved following information in the said HARQ formation:
1) formation ID;
2) data address is deposited this PUSCH and upward (is called for short, data_adr) address of the MAC PDU of carrying;
3) this sends the subframe numbers (being called for short PUSCH_FN, scope from 0 to 10239) of PUSCH, and the subframe numbers of reception next time PHICH (is called for short, PHICH_FN);
4) DCI0 authorization message comprises transformat, NDI sign etc.
To the TDD-LTE system, K, the subframe numbers decision that L is sent by TDD up-downgoing proportioning and upstream data, J=0 under attitude scheduling scene binds the subframe numbers decision that J is sent by up-downgoing proportioning and upstream data under the scheduling scene at TTI.
To the FDD-LTE system, its up-downgoing proportioning is fixed, K=L=4 under the dynamic dispatching scene, and J=0 binds K=4 under the scheduling scene, L=7, J=5 at TTI.
Simultaneously, for same HARQ formation, its relation that possibly send between the subframe numbers of upstream data is also fixed.
Its relation that possibly send between the subframe numbers of upstream data is:
SfnPusch
2 i＝SfnPusch
1 i+N*(K+L+J)
Wherein, SfnPusch
1 iFor this sends the subframe numbers of upstream data; SfnPusch
2 iBe the follow-up subframe numbers that can use identical HARQ formation to send upstream data; N>=1.
Wherein, Said TTI binds the scheduling scene when being illustrated in the up transmission of HARQ; Same HARQ is used for continuous 4 PUSCH and sends data; Bind the scheduling scene at TTI, above-mentioned each subframe numbers is represented continuous 4 subframe numbers that send first PUSCH among the data PUSCH in the up transmission of HARQ.
Prior LTE system ascending HARQ control method realization flow is:
1, UE detects the PDCCH channel at each descending sub frame;
2, when detecting DCI0, UE inquires about each HARQ formation;
If 3 have the HARQ formation that is associated with the DCI0 that receives, whether the NDI of NDI sign of then relatively being preserved in this HARQ formation and the DCI0 that receives identifies identical;
If 4 NDI identify different, carry out ascending HARQ on the PUSCH channel of the K sub-frame of MAC PDU after the subframe of said DCI0 place that the UE assembling is new and transmit new biography;
If NDI sign is identical, UE will use and carry out ascending HARQ on the PUSCH channel of the K sub-frame of MAC PDU after the subframe of said DCI0 place that this HARQ formation sends and transmit re-transmission last time;
If 5 do not find the HARQ formation that is associated with the DCI0 that receives, UE will select the HARQ formation of a free time, assemble on the PUSCH channel of the K sub-frame of new MAC PDU after the subframe of said DCI0 place and carry out ascending HARQ transmission new biography;
Wherein, said being associated is meant that the PHICH_FN+J that the HARQ formation is preserved is identical with the DCI0 that receives place subframe numbers;
6, UE with this PUSCH place subframe numbers, pairing next PHICH of this PUSCH that sends upstream data receive subframe numbers, this sends the data address of data and DCI0 information that this receives and records this and send in the employed HARQ formation;
7, UE receives on the corresponding descending sub frame of subframe numbers at the PHICH that said HARQ formation is preserved and detects PHICH;
(be called for short, ACK) information explains that network correctly receives these data of being sent of UE, and UE no longer upgrades the information in the said HARQ formation if 8 detect affirmation;
If 9 detect non-affirmation (be called for short, NACK) information or do not detect information, UE will retransmit the pairing MACPDU of said HARQ formation on the pairing next PUSCH subframe of this PHICH place subframe; Return step 6.
In the ascending HARQ process of transmitting; Network is after having carried out once indicating UE to carry out ascending HARQ transmission (new biography or re-transmission); If on the PUSCH of regulation subframe channel, do not receive the data of UE transmission or the error in data of reception, network can send nack message on the corresponding PHICH of this PUSCH, requires UE data retransmission on the PUSCH of next one regulation; If on the PUSCH of next one regulation, still can not correctly receive the data that UE sends, network can send NACK once more; If above-mentioned mutual through several times, still can not correctly receive the data that UE sends, network can send DCI0 and reconfigure UE ascending HARQ transmission resource, requires UE according to the resource data retransmission that reconfigures.
Can find out from the ascending HARQ control method realization flow of prior art; If UE is the situation of ACK information with the nack message flase drop that network sends; UE will no longer upgrade the information in the pairing HARQ formation of this PHICH; Can be not again on the PHICH channel of the follow-up subframe that the corresponding PHICH information of this HARQ formation possibly occur, do not detect feedback information to this HARQ formation yet, like this for network after the NACK feedback information that is directed against this HARQ formation that sends once more, UE can't detect and respond; And for the PDDCH channel, UE will detect always; When network still can't correctly receive the data that UE sends through PHICH feedback for several times and when sending DCI0 and requiring UE to retransmit; After UE receives this DCI0, because not renewal of the information in the HARQ formation, so UE can't find the HARQ formation that is associated with this DCI0; UE can select the HARQ formation of a free time and assemble new MAC PDU and carry out the ascending HARQ transmission at this moment; But the MAC PDU that should newly assemble, network also can be resolved incorrect, because the MAC PDU that retransmitted the last time that the network expectation receives; Can cause the HARQ transmission mechanism to lose efficacy like this, make data transmission fails.
