Description

The transmission method of ACK/NACK, method of reseptance and device thereof
Technical field
The present invention relates to wireless communication field, relate in particular to transmission method, method of reseptance and the device thereof of a kind of ACK/NACK.
Background technology
For LTE-A(Long Term Evolution Advanced, long-term evolution upgrading) multicarrier system, for supporting than LTE(Long Term Evolution, Long Term Evolution) the wideer system bandwidth of system, such as 100MHz, a kind of may be the frequency spectrum that directly distributes the 100M bandwidth, single-frequency spectral system schematic as shown in Figure 1; Another kind may be to adopt CA(Carrier Aggregation, carrier aggregation) technology, some spectrum aggregatings of existing system will be distributed to, constitute big bandwidth and supply with the long-term evolution multi-carrier system use, the up-downgoing carrier wave can asymmetricly dispose in the system at this moment, be that the user may take N1 〉=1 carrier wave and carries out downlink transfer, N2 〉=1 carrier wave carries out uplink, spectrum aggregating system schematic as shown in Figure 2.
The LTE-A system determines to support 5 carrier waves to carry out polymerization at most at present, the UE(User Equipment of LTE-A, subscriber equipment) need be at the ACK(Acknowledgment of a plurality of descending carriers of same sub-frame of uplink internal feedback and descending sub frame, positive acknowledgement)/and NACK(Negative Acknowledgment, Negative Acknowledgement) feedback information.
It is as shown in table 1 that corresponding same sub-frame of uplink carries out the descending sub frame of ACK/NACK feedback on each descending carrier, M carries out the descending sub frame number of ACK/NACK feedback for a corresponding sub-frame of uplink on each descending carrier, M is to different sub-frame of uplink and different TDD(Time Division Duplexing, time division duplex) uplink-downlink configuration value difference, the descending sub frame that is each the sub-frame of uplink correspondence shown in the table 1 is gathered
Figure 2011101712601100002DEST_PATH_IMAGE002
In the descending sub frame sum.Especially, for uplink-downlink configuration 0 and 5 at conventional CP(Cyclic Prefix, Cyclic Prefix) under, and the special descending sub frame of uplink-downlink configuration 0 and 4 under expansion CP, can not count, promptly M can not comprise this subframe, and UE is not to this subframe feeding back ACK/NACK.

The LTE-A system supports ACK/NACK at PUSCH(Physical Uplink Shared Channel, Physical Uplink Shared Channel) goes up transmission, for there not being corresponding PDCCH(Physical Downlink Control Channel, Physical Downlink Control Channel) SPS(Semi-persistent Scheduling, semi-continuous scheduling) PUSCH, because PUSCH does not have corresponding UL grant(uplink scheduling permission), therefore UE can't be according to the UL DAI(Downlink Assignment Index among the UL grant, descending allocation index) (comprise

Or ) determine the ACK/NACK feedback information of each descending carrier.At this situation, regulation UE transmits ACK/NACK in the following manner in the existing standard on PUSCH:
(1) if UE receives at least one PDSCH(Physical Downlink Shared Channel in the current sub-frame of uplink of correspondence carries out the descending sub frame of a plurality of descending carriers of ACK/NACK feedback, Physical Downlink Shared Channel) or the PDCCH that discharges of indicating downlink SPS resource, then UE determines that according to following mode PUSCH goes up the ACK/NACK feedback information of transmission:
A, be configured to adopt PUCCH (Physical Uplink Control Channel as ACK/NACK, Physical Uplink Control Channel) format(form) 3 o'clock, UE to the single codeword transmission mode or each descending carrier that carries out many codeword transmission pattern that the space merges produce M bit ACK/NACK feedback information; Descending sub frame on the descending carrier that does not receive the PDCCH that PDSCH or indicating downlink SPS resource discharge is produced 1 bit NACK as feedback information; To many codeword transmission pattern and do not carry out each descending carrier that the space merges and produce 2M bit ACK/NACK feedback information; Descending sub frame on the descending carrier that does not receive the PDCCH that PDSCH or indicating downlink SPS resource discharge is produced 2 bit NACK as feedback information, the ACK/NACK feedback information of each descending carrier cascaded up on PUSCH, transmit, wherein N is the descending carrier number of UE configuration/polymerization, and M is the corresponding descending sub frame number that carries out the ACK/NACK feedback at a sub-frame of uplink on each up-link carrier.
B, when ACK/NACK 2 descending carriers that have been configured to adopt PUCCH format 1b with channel selection and polymerization, UE transmission 4 bit informations at most on PUSCH:
When M=1, UE does not carry out the space merging to the ACK/NACK feedback information of many code words, the PDCCH of each code word on each descending carrier or the release of indicating downlink SPS resource is produced the ACK/NACK feedback information of 1 bit; The PDCCH that each code word on the descending carrier that does not receive the PDCCH that PDSCH or indicating downlink SPS resource discharge or indicating downlink SPS resource are discharged produces NACK as feedback information, the ACK/NACK feedback information of each descending carrier is cascaded up transmit on PUSCH;
When M=2, UE carries out the space merging to the ACK/NACK feedback information of many code words, each subframe on each descending carrier is produced the ACK/NACK feedback information of 1 bit; Descending sub frame on the descending carrier that does not receive the PDCCH that PDSCH or indicating downlink SPS resource discharge is produced NACK as feedback information, the ACK/NACK feedback information of each descending carrier is cascaded up on PUSCH, transmit;
When M=3 or 4, UE carries out the space merging to the ACK/NACK feedback information of many code words, corresponding 2 bit informations of each descending carrier represent that first descending sub frame begins continuous ACK number on the descending carrier, wherein 4 ACK can with a feedback states of 1 ACK or shared 2 bit informations of other ACK numbers, 2 bit informations of each descending carrier correspondence are cascaded up on PUSCH, transmit;
(2) if UE does not receive the PDCCH that PDSCH or indicating downlink SPS resource discharge in the current sub-frame of uplink of correspondence carries out all descending sub frames of a plurality of descending carriers of ACK/NACK feedback, UE transferring ACK/NACK feedback information not on PUSCH then.
Consider ACK/NACK on PUSCH by mapping that upstream data is punched, frequency domain is placed from the low frequency to the high frequency after the four row symbols elder generation time domain of pilot tone both sides, ascending control information as shown in Figure 3 is at PUSCH ascending physical signal resource mapping schematic diagram, and there are the following problems for the mode of UE above-mentioned transmission ACK/NACK on PUSCH:
If transmit at the PDCCH that the current sub-frame of uplink of correspondence carries out existing PDSCH scheduled transmission or indicating downlink SPS resource to discharge in the descending sub frame of ACK/NACK feedback the base station, consider that may there be the situation of the PDCCH that loses PDSCH or the release of indicating downlink SPS resource in UE, base station and UE may be inconsistent to the understanding of whether having transmitted ACK/NACK on the PUSCH.Therefore, the base station need be carried out the DTX(Discontinuous Transmission of ACK/NACK feedback information, discontinuous transmission to SPS PUSCH) detect, whether transmitted the ACK/NACK feedback information to judge UE.
But there is certain error probability in the DTX of ACK/NACK feedback information; If this has sent ACK/NACK UE on PUSCH, but when the DTX testing result that ACK/NACK is gone up to PUSCH in the base station is DTX, the base station thinks that UE does not send ACK/NACK on PUSCH, then the ACK/NACK information of UE feedback has been lost in the base station, to cause descending redundant retransmission, and ACK/NACK information decoded as upstream data, thereby influence the correct reception of upstream data; If this does not send ACK/NACK UE on PUSCH, but when the DTX testing result that ACK/NACK is gone up to PUSCH in the base station is non-DTX, the base station thinks that UE has sent ACK/NACK on PUSCH, then decode upstream data in the base station as ACK/NACK information, obtained wrong ACK/NACK feedback information, to cause descending redundant retransmission or erroneous transmissions, also influence the correct reception of upstream data simultaneously.
In addition, the resource transmitted on PUSCH of ACK/NACK is the resource offset parameter according to different ACK/NACK feedback bits length and the pre-configured relative upstream data of ACK/NACK
Figure 2011101712601100002DEST_PATH_IMAGE012
Determine.Resource offset is the shared RE(Resource Element of ACK/NACK feedback information, Resource Unit) adjustment amount of the number RE number shared with respect to the upstream data on the PUSCH is to guarantee the transmission reliability of the ACK/NACK under the different upstream data MCS grades.
Because ACK/NACK is different with many code words (2 code words) last transmission means of PUSCH in single codeword, when many codeword transmission of PUSCH, ACK/NACK is mapped in every layer and repeats transmission, ACK/NACK is different with transmission performance on many codeword transmission PUSCH in single codeword transmission, for fear of the wasting of resources, the PUSCH of single codeword and many codeword transmission is defined calculating respectively
Figure 49956DEST_PATH_IMAGE012
, For high-level signaling pre-configured, promptly based on PUSCH transfer bandwidth in a period of time and MCS(modulation and coding style, modulation coding mode) the isoparametric variation demand of grade and setting.
For SPS PUSCH, the transmission bandwidth of PUSCH and MCS grade be at a period of time internal fixation, therefore, determines based on the PUSCH transfer bandwidth of dynamic change and MCS grade
Figure 691339DEST_PATH_IMAGE012
No longer be applicable to the ACK/NACK transmission on the SPS PUSCH.
In addition, for TDD system uplink-downlink configuration 0 or FDD system, owing to do not have 2 bit UL DAI among the UL grant, so there are the problems referred to above in ACK/NACK when transmitting too on PUSCH.
In realizing process of the present invention, the inventor finds to exist at least in the prior art following problem:
In LTE-A CA system, for the SPS PUSCH that does not have corresponding PDCCH, or the PUSCH under the TDD uplink-downlink configuration 0, or the PUSCH in the FDD system, if UE does not all receive the PDCCH that PDSCH or indicating downlink SPS resource discharge in the current sub-frame of uplink of correspondence carries out all descending sub frames of ACK/NACK feedback, UE transferring ACK/NACK feedback information not on PUSCH then.When the UE downlink data is lost, will cause base station and UE to whether understanding differently of transferring ACK/NACK causes on the PUSCH, thereby influence the detection performance of ACK/NACK and upstream data.

Determine the ACK/NACK feedback information of each descending carrier, if UE does not receive the PDCCH that PDSCH or indicating downlink SPS resource discharge in the current sub-frame of uplink of correspondence carries out all descending sub frames of ACK/NACK feedback, UE transferring ACK/NACK feedback information not on PUSCH then; ACK/NACK DTX detection is carried out to need SPS PUSCH in the base station, whether has transmitted the ACK/NACK feedback information to judge UE.Make mistakes if the ACK/NACK DTX of base station detects, then can influence the demodulation performance of base station upstream data and ACK/NACK feedback information.
At the problems referred to above, the embodiment of the invention has proposed the transmission method of a kind of ACK/NACK feedback information at PUSCH, to avoid base station and UE to whether understanding differently of transferring ACK/NACK causes on the PUSCH, and then avoid the base station that the DTX that PUSCH goes up the ACK/NACK feedback information is detected, improve the transmission reliability of upstream data and ACK/NACK feedback information.
Below in conjunction with accompanying drawing the embodiment of the invention is described in detail.
Embodiment one
The embodiment of the invention provides the transmission method of a kind of ACK/NACK, and as shown in Figure 4, this method may further comprise the steps:
Step 401, UE determines the ACK/NACK feedback information that transmits on PUSCH.
In the embodiment of the invention, in the LTE-A system, when the ACK/NACK feedback information when PUSCH transmits, if the PUSCH that is used for transmitting uplink control information that UE determines is the PUSCH that does not have corresponding PDCCH, or be the PUSCH under the uplink-downlink configuration 0 in the TDD system, or when being PUSCH in the FDD system, no matter whether UE receives the PDCCH that PDSCH or indicating downlink SPS resource discharge in the needs of current sub-frame of uplink correspondence carry out the descending sub frame of ACK/NACK feedback, UE is all transmission ACK/NACK feedback information on the PUSCH (if promptly UE does not receive the PDCCH of PDSCH or the release of indicating downlink SPS resource in the sub-frame of uplink that correspondence sends PUSCH carries out the descending sub frame of ACK/NACK feedback, UE also need transmit the ACK/NACK feedback information on PUSCH).
Particularly, promptly for there not being UL DAI(to include but not limited to
Figure 949189DEST_PATH_IMAGE014
Or ) PUSCH of information, no matter whether UE receives the PDCCH that PDSCH or indicating downlink SPS resource discharge in the needs of current sub-frame of uplink correspondence carry out all descending sub frames of all descending carriers of ACK/NACK feedback, and UE is transmission ACK/NACK feedback information on these PUSCH all.
In the embodiment of the invention, UE determines that the mode of the ACK/NACK feedback information that transmits comprises on PUSCH:
Mode one: UE counts the descending sub frame that corresponding current sub-frame of uplink on N and each descending carrier carries out the ACK/NACK feedback according to the descending carrier of self configuration and counts M, determines ACK/NACK number of bits of feedback and feedback information sequence that UE need transmit on PUSCH.
(1) at each descending carrier, when this descending carrier was single codeword transmission mode or many codeword transmission pattern and the merging of employing space, UE need produce the ACK/NACK feedback information of M bit to this descending carrier; When this descending carrier is many codeword transmission pattern and when not adopting the space to merge, UE need produce the ACK/NACK feedback information of 2M bit to this descending carrier.Wherein M is the descending sub frame number that corresponding current sub-frame of uplink carries out the ACK/NACK feedback.
(2) UE produces NACK as the ACK/NACK feedback information to the descending sub frame of the PDCCH that do not receive PDSCH or indicating downlink SPS resource and discharge; Wherein, at each descending carrier, when this descending carrier was single codeword transmission mode or many codeword transmission pattern and the merging of employing space, UE produced 1 bit NACK to descending sub frame; When this descending carrier is many codeword transmission pattern and when not adopting the space to merge, UE produces 2 bit NACK to descending sub frame.
At above-mentioned two kinds of situations, when UE transmitted the ACK/NACK feedback information on PUSCH, this UE transmitted on PUSCH with the ACK/NACK feedback information cascade of each descending carrier correspondence together.
Mode two: UE merges mode according to the PUCCH transformat and/or the ACK/NACK of the transferring ACK/NACK feedback information of current configuration or use, determines ACK/NACK number of bits of feedback and the feedback information sequence transmitted on PUSCH; Be that UE merges the different of mode according to the PUCCH transformat with ACK/NACK, adopt distinct methods to determine that PUSCH goes up the ACK/NACK feedback information bits number and the feedback information sequence of transmission.
(1) current configuration of UE or the PUCCH transformat that uses are that UE adopts PUCCH format 3 forms transferring ACK/NACK feedback information on PUCCH as PUCCH format 3() time, UE determines that the mode of the ACK/NACK feedback information that transmits comprises on PUSCH:
At each descending carrier, when this descending carrier was single codeword transmission mode or many codeword transmission pattern and the merging of employing space, UE need produce the ACK/NACK feedback information of M bit to this descending carrier; When this descending carrier is many codeword transmission pattern and when not adopting the space to merge, UE need produce the ACK/NACK feedback information of 2M bit to this descending carrier.Wherein M is the descending sub frame number that corresponding current sub-frame of uplink carries out the ACK/NACK feedback.
UE produces NACK as the ACK/NACK feedback information to the descending sub frame of the PDCCH that do not receive PDSCH or indicating downlink SPS resource and discharge; Wherein, at each descending carrier, when this descending carrier was single codeword transmission mode or many codeword transmission pattern and the merging of employing space, UE produced 1 bit NACK to descending sub frame; When this descending carrier is many codeword transmission pattern and when not adopting the space to merge, UE produces 2 bit NACK to descending sub frame.
When UE transmitted the ACK/NACK feedback information on PUSCH, this UE transmitted on PUSCH with the ACK/NACK feedback information cascade of each descending carrier correspondence together.
(2) current configuration of UE or the PUCCH transformat that uses are that UE adopts PUCCH format 1b with channel selection form transferring ACK/NACK feedback information on PUCCH as PUCCH format 1b with channel selection() time, UE determines that the mode of the ACK/NACK feedback information that transmits comprises on PUSCH:
When M=1, UE does not carry out the space merging to the ACK/NACK feedback information of many code words; The PDCCH that each code word on each descending carrier or indicating downlink SPS resource are discharged produces the ACK/NACK feedback information of 1 bit, when promptly each descending carrier being produced this descending carrier of M(and is the single codeword transmission) or this descending carrier of 2M(when being many codeword transmission) bit ACK/NACK feedback information; Wherein, UE produces NACK as the ACK/NACK feedback information to the PDCCH that each code word on the descending carrier of the PDCCH that do not receive PDSCH or indicating downlink SPS resource and discharge or indicating downlink SPS resource discharge; The ACK/NACK feedback information of each descending carrier cascaded up on PUSCH, transmit.
When M=2, UE carries out the space merging to the ACK/NACK feedback information of many code words; Each descending sub frame on each descending carrier is produced the ACK/NACK feedback information of 1 bit, promptly each descending carrier common property is given birth to M bit ACK/NACK feedback information; Wherein, UE produces NACK as the ACK/NACK feedback information to the descending sub frame on the descending carrier of the PDCCH that do not receive PDSCH or indicating downlink SPS resource and discharge; The ACK/NACK feedback information of each descending carrier cascaded up on PUSCH, transmit.
When M=3 or 4, UE produces the ACK/NACK feedback information that the Z bit merges to each descending carrier, and this Z bit information represents that first descending sub frame begins continuous ACK number on this descending carrier, the promptly correct continuously descending sub frame number that receives.
Wherein, M is the descending sub frame number that corresponding current sub-frame of uplink carries out the ACK/NACK feedback.
For example, each descending carrier is produced the ACK/NACK feedback information (at first the ACK/NACK to many code words carries out the space merging) that the Z=2 bit merges, wherein 4 ACK can with a feedback states of 1 ACK or shared 2 bit informations of other ACK numbers, 2 bit informations of each descending carrier correspondence are cascaded up on PUSCH, transmit; As shown in table 2, the merging feedback bits of each carrier wave that merges for channel selection time domain.
Table 2
(3) ACK/NACK merging mode comprises that time domain ACK/NACK merges mode, this time domain ACK/NACK merging mode is: the descending sub frame of the M on each carrier wave is divided into the individual descending sub frame group of L(1≤L≤M), Ti(1≤Ti in each descending sub frame group≤M, the individual subframe of 1≤i≤L) merges the ACK/NACK feedback information of corresponding same numeral position in a plurality of descending sub frames in each descending sub frame group on the same descending carrier.When UE adopts above-mentioned time domain ACK/NACK to merge mode on PUCCH, the A bit ACK/NACK feedback information on the descending sub frame packet count L that UE merges according to time domain on last each descending carrier that adopts of PUCCH, each descending carrier after the merging of every group of descending sub frame correspondence and the descending carrier of UE polymerization/activation are counted N, determine ACK/NACK feedback information bits number and the feedback information sequence transmitted on PUSCH.
Further, when UE adopts above-mentioned time domain ACK/NACK to merge mode to the ACK/NACK feedback information on each descending carrier, UE can obtain the A bit ACK/NACK feedback information of each descending sub frame group correspondence on each descending carrier, with the A bit ACK after the merging of each descending sub frame group correspondence on a plurality of descending carriers/cascade of NACK feedback information together, obtain A * L * N bit ACK/NACK feedback information, on PUSCH, transmit.
In the embodiment of the invention,
Figure 2011101712601100002DEST_PATH_IMAGE020
