By applying the technical scheme in the embodiment of the invention, the transmission and/or the indication of a PDCCH (physical downlink control channel) which is released by a downlink SPS (smart peripheral subsystem) resource in a PDSCH (physical downlink shared channel) on a corresponding downlink main carrier wave with a DAI (direct access information) value which is larger than 1 and an information indication PUCCH (physical uplink control channel) format3 channel resource which is transmitted in the PDSCH on a corresponding downlink auxiliary carrier wave in an ACK/NACK resource indication domain in the PDCCH are realized, and the ACK/NACK feedback information is transmitted by adopting the PUCCH format3 scheme when data is only received on a downlink main carrier ware by a terminal device which is configured with multiple downlink carrier waves, therefore, the misunderstanding of the transmission scheme to the ACK/NACK feedback information between a base station and the terminal device is avoided, and the reliability and the efficiency of transmitting the ACK/NACK feedback information are enhanced.

Description

The transmission method of ACK/NACK feedback information and equipment
Technical field
The present invention relates to communication technical field, particularly a kind of transmission method of ACK/NACK feedback information and equipment.
Background technology
For LTE-A(Long Term Evolution Advanced, long-term evolution upgrading) system, for supporting than LTE(Long Term Evolution, Long Term Evolution) the wider system bandwidth of system, such as 100MHz, may be a frequency spectrum that directly distributes 100M bandwidth, as shown in Figure 1; A kind of may be CA(Carrier Aggregation, carrier aggregation) technology, be about to distribute to some spectrum aggregatings of existing system, gather into large bandwidth and supply with the use of LTE-A multicarrier system, now, in system, up-downgoing carrier wave can asymmetricly configure, and user may take N >=1 carrier wave and carries out downlink transfer, M >=1 carrier wave carries out uplink, as shown in Figure 2.
LTE-A system is determined and can be supported at most 5 carrier waves to carry out polymerization at present, a LTE-A UE(User Equipment, subscriber equipment, be terminal equipment) need to be at the ACK(Acknowledgement of the corresponding a plurality of descending carriers of same sub-frame of uplink internal feedback and descending sub frame, positive acknowledgement)/NACK(Negative Acknowledgement, Negative Acknowledgement) feedback information.Be that UE is at sub-frame of uplink nmiddle by the descending sub frame on the corresponding a plurality of descending carriers of feedback n- kon the ACK/NACK feedback information of data, k∈ k, set kuplink-downlink configuration and the concrete subframe numbering of value and system relevant, as shown in table 1.Therefore,, in LTE-A system, defined a kind of new PUCCH(Physical Uplink Control Channel, Physical Uplink Control Channel) format(form) 3 schemes are as the multiplexing transmission scheme of many bit ACK/NACK feedback informations.The maximum transmitted bit number of PUCCH format 3 transmission plans is 20 bits.For fear of base station and UE, understanding differently of the bit number of ACK/NACK feedback information caused the bit number that the descending carrier of UE based on configuration and the transmission mode of each descending carrier are determined ACK/NACK feedback information.Especially, for uplink-downlink configuration 0 and 5 under regular circulation prefix (CP, Cyclic Prefix), and the special descending sub frame of uplink-downlink configuration 0 and 4 under expansion CP, can not count, M can not comprise this subframe, and UE is not to this subframe feeding back ACK/NACK feedback information.

Figure DEST_PATH_IMAGE004
At LTE-A TDD(Time Division Duplex, time division duplex) in system, the UE of Physical Uplink Control Channel PUCCH format 3 transferring ACKs/NACK is used in configuration, base station by semi-static in advance by high-level signaling be 4 PUCCH format 3 channel resources of its configuration, when carrying out downlink data dispatching, by down control channel PDCCH, indicate dynamically UE specifically to use which channel resource to transmit PUCCH.
Determine at present in LTE-A TDD system, for the Rel-10 UE that has configured a plurality of descending carriers, the corresponding PDSCH(Physical Downlink Shared Channel transmitting on downlink main carrier to carry, Physical Downlink Shared Channel) PDCCH(Physical Downlink Control Channel, Physical Downlink Control Channel) and indicating downlink SPS(Semi-persistant Scheduling, semi-continuous) TPC(Transmitter Power Control in the PDCCH that discharges of resource, transmission power control) territory is for load power control command, TPC territory (2 bit) in the PDCCH of the corresponding PDSCH transmitting on descending auxiliary carrier wave is as ARI(ACK/NACK Resource Indicator, the indication of ACK/NACK resource), PUCCH format 3 channel resources of indicating a configuration to use to UE, this channel resource is a group in 4 groups of pre-configured PUCCH format 3 channel resources of high level, and the ARI carrying out in a plurality of PDCCH that the downlink data of ACK/NACK feedback is corresponding at same sub-frame of uplink should indicate identical resource.For single port transmission, only have format 3 resources in one group, for multiport (2 port) transmission, one group comprises 2 format 3 resources, respectively corresponding different antenna ports.If UE has only received data (PDCCH that PDSCH or indicating downlink SPS resource discharge) on downlink main carrier to carry, due to the TPC carrying in the PDCCH of these data of scheduling is power control command but not ARI, UE cannot obtain PUCCH format 3 channel resources, therefore, cannot use PUCCH format 3 transmission plan transferring ACK/NACK feedback informations, now, UE can only adopt PUCCH format 1a/1b or channel selection(channel to select in PUCCH format 1a/1b resource) transmission plan transmission ACK/NACK feedback information.When base station exists transfer of data and UE while having lost the data on descending auxiliary carrier wave on descending auxiliary carrier wave, base station and UE may be inconsistent to the understanding of ACK/NACK transmission plan, therefore, blind check need to be carried out in base station on PUCCH format 3 and PUCCH format 1a/1b channel resource, could determine which kind of transmission plan UE adopts, thereby correctly obtain the ACK/NACK feedback information that UE sends.
In addition, for the Rel-10 UE that has only configured a descending carrier, many bit ACK/NACK the feedback informations of PUCCH format 3 transmission also can configuration UE be used in base station, owing to now not needing that the ACK/NACK feedback information on single carrier is carried out to space merging (Spatial bundling), can improve ACK/NACK efficiency of transmission.Now, DAI(Downlink Assignment Index on a descending carrier of configuration on (being downlink main carrier to carry), descending Allotment Serial Number) the TPC territory in the PDCCH that value is 1 is for load power control signal, and DAI value is greater than TPC territory (2 bit) in 1 PDCCH as ARI, PUCCH format 3 channel resources of indicating a configuration to use to UE, this channel resource is a group in 4 groups of pre-configured PUCCH format 3 channel resources of high level, and the ARI carrying out in a plurality of PDCCH that the downlink data of ACK/NACK feedback is corresponding at same sub-frame of uplink should indicate identical resource.For single port transmission, only have format 3 resources in one group, for multiport (2 port) transmission, one group comprises 2 format 3 resources, respectively corresponding different antenna ports.If UE has only received SPS PDSCH in feedback window, UE feeds back the ACK/NACK feedback information that SPS PDSCH is corresponding in the PUCCH resource being configured by high level.If UE has only received the PDCCH that the value of DAI is 1 in feedback window, UE feeding back ACK/NACK feedback information in Rel-8 resource corresponding to this PDCCH.
Therefore,, in LTE-A TDD system, when having configured the Rel-10 UE of a plurality of descending carriers and only receive data on downlink main carrier to carry, how to use PUCCH format 3 scheme transferring ACK/NACK feedback informations also there is no clear and definite scheme.
In realizing the process of the embodiment of the present invention, applicant finds that prior art at least exists following problem:
In LTE-A TDD system, for the Rel-10 UE that has configured a plurality of descending carriers, when UE adopts PUCCH format 3 scheme transferring ACK/NACK feedback information, if only receive data on downlink main carrier to carry, because UE cannot obtain PUCCH format 3 channel resources, can not adopt PUCCH format 3 scheme transferring ACK/NACK feedback informations, can only in PUCCH format 1a/1b resource, adopt PUCCH format 1a/1b or channel selection scheme transferring ACK/NACK feedback information, ACK/NACK transmission reliability and efficiency have been affected.

Embodiment
As stated in the Background Art, for thering is the terminal equipment of CA ability in LTE-A system, can adopt PUCCH format3 to transmit many bit ACK/NACK feedback informations.But, when such terminal equipment has been configured a plurality of descending carriers, but while only receiving data on downlink main carrier to carry, how to adopt PUCCH format 3 transferring ACKs/NACK feedback information, but also there is no clear and definite scheme.
Based on above reason, the embodiment of the present invention has provided a kind of by information indication PUCCH format 3 channel resources in the ACK/NACK resource indication territory in PDCCH, to make, between terminal equipment and base station, adopt PUCCH format3 to transmit the method for many bit ACK/NACK feedback informations, even when terminal equipment only receives transfer of data on downlink main carrier to carry, also can adopt PUCCH format 3 transferring ACKs/NACK feedback information.
As shown in Figure 3, the schematic flow sheet of the transmission method of a kind of ACK/NACK feedback information proposing for the embodiment of the present invention, the method specifically comprises the following steps:
Step S301, M the descending sub frame of terminal equipment in N descending carrier that has configured a plurality of descending carriers receive data.
Wherein, N >=1,1≤M≤4, the corresponding ACK/NACK feedback information of data in M descending sub frame transmits in same sub-frame of uplink.
Step S302, terminal equipment are determined PUCCH format 3 channel resources according to the information in the ACK/NACK resource indication territory in the PDCCH receiving.
Wherein, PDCCH comprises that the value of DAI is greater than the PDCCH of PDSCH transmission and the release of indicating downlink SPS resource on 1 corresponding downlink main carrier to carry, and the PDCCH of PDSCH transmission on corresponding descending auxiliary carrier wave, be that PDCCH can be divided into two classes, one class is that the value of DAI is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, and another kind of be the PDCCH that on corresponding descending auxiliary carrier wave, PDSCH transmits.
In concrete application scenarios, the value of above-mentioned DAI is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, and specifically comprises one or more of following information:
Dispatch the PDCCH of dynamic PDSCH;
The PDCCH that indication SPS PDSCH activates;
The PDCCH that indication SPS resource discharges.
In the process of the technical scheme proposing in the enforcement embodiment of the present invention, whether identical according to the ACK/NACK resource indication information in the above-mentioned two class PDCCH that send in system, the deterministic process for PUCCH format 3 channel resources in this step comprises following two kinds of modes.
In mode one, system, adopt the value of DAI to be greater than indicated PUCCH format 3 channel resources in ACK/NACK resource indication territory in the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, the mode that PUCCH format 3 channel resources indicated with ACK/NACK resource indication territory in the PDCCH of PDSCH transmission on corresponding descending auxiliary carrier wave are identical is indicated PUCCH format 3 channel resources.
When terminal equipment only receives the PDCCH that PDSCH and/or indicating downlink SPS resource discharge on downlink main carrier to carry, and when the value that receives DAI is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, or when terminal equipment receives PDSCH on descending auxiliary carrier wave, terminal equipment is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge according to the value of DAI, and/or the information in the ACK/NACK resource indication territory in the arbitrary PDCCH in the PDCCH of PDSCH transmission on corresponding descending auxiliary carrier wave is determined PUCCH format 3 channel resources.
In this way, specifically according to the ACK/NACK resource indication territory in any class PDCCH, carry out determining of PUCCH format 3 channel resources, need to determine according to corresponding information reception condition, be described as follows.
(1) when terminal equipment only receives the PDCCH that PDSCH and/or indicating downlink SPS resource discharge on downlink main carrier to carry, and when the value that receives DAI is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, the information that terminal equipment is greater than according to the value of DAI in the ACK/NACK resource indication territory in the arbitrary PDCCH in the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge is determined PUCCH format 3 channel resources.
(2), when terminal equipment only receives PDSCH on descending auxiliary carrier wave, terminal equipment is determined PUCCH format 3 channel resources according to the information in the ACK/NACK resource indication territory in the arbitrary PDCCH in the PDCCH of PDSCH transmission on descending auxiliary carrier wave.
(3) when value that terminal equipment receives PDCCH that PDSCH and/or indicating downlink SPS resource discharge and DAI on downlink main carrier to carry is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, and while receiving PDSCH on descending auxiliary carrier wave, terminal equipment is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge according to the value of DAI, and the information in the ACK/NACK resource indication territory in any one PDCCH in the PDCCH of PDSCH transmission on corresponding descending auxiliary carrier wave is determined PUCCH format 3 channel resources.
In this way, because the value of two class PDCCH(DAI is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, and the PDCCH of PDSCH transmission on corresponding descending auxiliary carrier wave) information content in ACK/NACK resource indication territory is identical, so, no matter apply the ACK/NACK resource of any class PDCCH and indicate the information in territory, determined PUCCH format 3 channel resources of terminal equipment are all the same, in fact, in above-mentioned (1) to (3), just guaranteeing to receive after PDCCH respectively, according to corresponding PDCCH, determine PUCCH format 3 channel resources, above-mentioned (1) to (3) can be merged, corresponding same PUCCH format 3 resources are determined situation.In addition, if exist a plurality of in same class PDCCH, the information in the ACK/NACK resource indication territory in each PDCCH should be indicated identical PUCCH format 3 channel resources, therefore, in the manner, terminal equipment adopts definite PUCCH format 3 channel resources of the information in the indication of the ACK/NACK resource in an arbitrary PDCCH who receives territory in above-mentioned two class PDCCH all the same.
It is to be noted, for the manner, in order to guarantee the consistency of processing rule, situation about not being inconsistent from the rule setting if there is the information in the ACK/NACK resource indication territory in the actual PDCCH receiving of terminal equipment (as different in the information content in the ACK/NACK resource indication territory in two class PDCCH), so, terminal equipment can think that mistake appears in current scheduling, and do not carry out the transmission of ACK/NACK feedback information, or, also can select indicated PUCCH format 3 channel resources in ACK/NACK resource indication territory in the PDCCH of a type to carry out the transmission of ACK/NACK feedback information, such variation does not affect the protection range of the embodiment of the present invention.
Further, in the manner, no matter be that scene in above-mentioned (1) to (3), terminal equipment is all to determine ACK/NACK feedback information according to the transmission mode of the descending carrier of the descending carrier of configuration and each configuration, to avoid terminal equipment and base station to cause understanding differently of ACK/NACK number of bits of feedback.For example, terminal equipment configuration N descending carrier, the transmitted codewords of each descending carrier is C i, for the carrier wave C of single codeword transmission mode i=1, for the carrier wave C of many codeword transmission pattern i=2, M is the descending sub frame number that need to carry out ACK/NACK feedback corresponding to each sub-frame of uplink, as shown in the table 1 of background technology part, when being no more than maximum transmitted bit number 20 bit of PUCCH format 3, the ACK/NACK feedback information of many code words is not carried out to space merging, the ACK/NACK number of bits of feedback that terminal equipment produces is, terminal equipment produces ACK/NACK feedback information to each descending sub frame on each descending carrier according to transmission mode, to producing 2 bit ACK/NACK feedback information in each descending sub frame on the descending carrier of many codeword transmission pattern, respectively corresponding each code word, each descending sub frame on the descending carrier of single codeword transmission mode is produced to 1 bit ACK/NACK feedback information, the descending sub frame not receiving on the descending carrier of many codeword transmission pattern of data is produced to 2 bit NACK as feedback information, the descending sub frame not receiving on the descending carrier of single codeword transmission mode of data is produced to 1 bit NACK as feedback information, when surpassing maximum transmitted bit number 20 bit of PUCCH format 3, need to carry out space merging to the ACK/NACK feedback information of many code words, now terminal equipment carries out logical AND operation (being that space merges) to the ACK/NACK feedback information of a plurality of code words in same descending sub frame, each descending sub frame on each descending carrier is produced to 1 bit ACK/NACK feedback information.
In mode two, system, adopt the value of DAI to be greater than indicated PUCCH format 3 channel resources in ACK/NACK resource indication territory in the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, the different mode of PUCCH format 3 channel resources indicated from ACK/NACK resource indication territory in the PDCCH of PDSCH transmission on corresponding descending auxiliary carrier wave is indicated PUCCH format 3 channel resources.
Terminal equipment is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge according to the value of DAI, or the information in the ACK/NACK resource indication territory in the PDCCH of PDSCH transmission on corresponding descending auxiliary carrier wave is determined PUCCH format 3 channel resources.
In this way, specifically according to the ACK/NACK resource indication territory in any class PDCCH, carry out determining of PUCCH format 3 channel resources, need to determine according to corresponding information reception condition, be described as follows.
(1) when terminal equipment only receives the PDCCH that PDSCH and/or indicating downlink SPS resource discharge on downlink main carrier to carry, and when the value that receives DAI is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, terminal equipment is greater than the information in the ACK/NACK resource indication territory in arbitrary PDCCH in the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge and determines PUCCH format 3 channel resources according to the value of DAI.
Under this kind of scene, terminal equipment, according to the transmission mode of downlink main carrier to carry, is only determined ACK/NACK feedback information to downlink main carrier to carry, to improve efficiency of transmission and the performance of ACK/NACK feedback information.
Further, under this kind of scene, terminal equipment can not carry out space merging to the ACK/NACK feedback information of the many code words in same descending sub frame on downlink main carrier to carry, to improve ACK/NACK efficiency of transmission, avoids unnecessary system to retransmit.For example, the descending sub frame number that need to carry out ACK/NACK feedback that current sub-frame of uplink is corresponding is M, as shown in the table 1 in background technology part, when downlink main carrier to carry is single codeword transmission mode, terminal equipment produces 1 bit ACK/NACK feedback information to each descending sub frame in the descending sub frame of M on downlink main carrier to carry, to not receiving the descending sub frame of data, produce NACK as feedback information, obtain M bit ACK/NACK feedback information; When downlink main carrier to carry is many codeword transmission pattern, terminal equipment produces 2 bit ACK/NACK feedback information to each descending sub frame in the descending sub frame of M on downlink main carrier to carry, each code word in respectively corresponding each descending sub frame, to not receiving the descending sub frame of data, produce 2 bit NACK as feedback information, obtain 2M bit ACK/NACK feedback information.
(2), when terminal equipment receives PDSCH on descending auxiliary carrier wave, terminal equipment is determined PUCCH format 3 channel resources according to the information in the ACK/NACK resource indication territory in the PDCCH of PDSCH transmission on descending auxiliary carrier wave.
Under this kind of scene, terminal equipment is determined ACK/NACK feedback information according to the transmission mode of the descending carrier of the descending carrier of configuration and each configuration, to avoid terminal equipment and base station to cause understanding differently of ACK/NACK number of bits of feedback.Concrete ACK/NACK number of bits of feedback determine and the production process of ACK/NACK feedback bits with described in mode one, be not repeated herein.
It is to be noted, because the value of two class PDCCH(DAI is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, and the PDCCH of PDSCH transmission on corresponding descending auxiliary carrier wave) information content in ACK/NACK resource indication territory is different, so, the scene (1) of terminal equipment in aforesaid way two is different with determined PUCCH format 3 channel resources in scene (2), in fact, by using different PUCCH format 3 channel resources to send ACK/NACK feedback information, the reality that can distinguish the ACK/NACK feedback information of different terminal equipment reception data cases and terminal equipment transmission is the feedback information producing according to which or which descending carrier.
It is to be noted, for two kinds of above-mentioned modes, in order to guarantee in the situation that there is a plurality of descending carrier, terminal equipment can be determined PUCCH format 3 channel resources according to the information in the ACK/NACK resource indication territory of the PDCCH of respective type, can not produce major gap of understanding because of the information gap in a plurality of PDCCH of same kind, so, need to carry out following setting.
It is identical that the value of a plurality of DAI that A, terminal equipment are received is greater than PUCCH format 3 channel resources indicated in the ACK/NACK resource indication territory in the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge.
PUCCH format 3 channel resources indicated in ACK/NACK resource indication territory on the received descending auxiliary carrier wave of a plurality of correspondences of B, terminal equipment in the PDCCH of PDSCH transmission are identical.
Therefore, for mode one, no matter terminal equipment is determined PUCCH format 3 channel resources according to the ACK/NACK resource indication territory in which PDCCH in which class in 2 class PDCCH, and determined resource is all same/mono-group resource; For mode two, when terminal equipment is selected a class PDCCH for definite PUCCH format 3 channel resource according to reception condition, no matter terminal equipment is determined PUCCH format 3 channel resources according to the ACK/NACK resource indication territory in which PDCCH in this class PDCCH, and determined resource is all same/mono-group resource.
It is to be noted; when the information in the ACK/NACK resource indication territory in a plurality of PDCCH that terminal equipment receives does not meet above-mentioned A and B condition; terminal equipment can think that mistake appears in current scheduling; and do not carry out the transmission of ACK/NACK feedback information; or; can in receiving the PDCCH of a type corresponding to scene, select indicated PUCCH format 3 channel resources in ACK/NACK resource indication territory in PDCCH to carry out the transmission of ACK/NACK feedback information, such variation does not affect the protection range of the embodiment of the present invention yet.
It is pointed out that when PUCCH format 3 is single port transmission mode a resource in corresponding high-rise pre-configured a plurality of PUCCH format 3 channel resources of indicated value in the resource indication territory under above-mentioned two kinds of modes in PDCCH, when PUCCH format3 is multiport (2 port) transmission mode, be SORTD(Spatial Orthogonal Resource Transmit Diversity, orthogonal space resource sends diversity) during pattern, the value of DAI is greater than one group of resource in corresponding high-rise pre-configured many groups PUCCH format 3 channel resources of indicated value in the resource indication territory in the PDCCH of PDSCH transmission on PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge and corresponding descending auxiliary carrier wave, every group of resource comprises 2 PUCCH format 3 channel resources, the antenna port that difference is corresponding different.
It is pointed out that ACK/NACK resource in above-mentioned PDCCH indication territory can be the reusing of existing bit field in PDCCH, for example, reuse 2 bit TPC indication territories, or the bit field for newly increasing in PDCCH.
Step S303, terminal equipment adopt PUCCH format 3 scheme transferring ACK/NACK feedback informations on definite PUCCH format 3 channel resources.
Corresponding, in order to realize above-mentioned technical scheme, in base station side, need to complete the configuration of PUCCH format 3 channel resources and the processing of indication, concrete processing procedure process schematic diagram as shown in Figure 4, comprises the following steps:
Step S401, base station determine that configuration is to PUCCH format 3 channel resources that configured the terminal equipment of a plurality of descending carriers.
Step S402, base station are carried at determined PUCCH format 3 channel resources in the ACK/NACK resource indication territory of PDCCH and send to terminal equipment.
Wherein, PDCCH comprises that the value of DAI is greater than the PDCCH of PDSCH transmission and the release of indicating downlink SPS resource on 1 corresponding downlink main carrier to carry, and the PDCCH of PDSCH transmission on corresponding descending auxiliary carrier wave, be that PDCCH can be divided into two classes, one class is that the value of DAI is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, and another kind of be the PDCCH that on corresponding descending auxiliary carrier wave, PDSCH transmits.
In concrete application scenarios, the value of above-mentioned DAI is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, and specifically comprises one or more of following information:
Dispatch the PDCCH of dynamic PDSCH;
The PDCCH that indication SPS PDSCH activates;
The PDCCH that indication SPS resource discharges.
Owing to there is the above-mentioned PDCCH of two types, whether identical for the information content in the ACK/NACK resource indication territory in two kinds of PDCCH, base station can send the ACK/NACK resource indication information in PDCCH by following two kinds of modes.
Certainly; in actual applications, determining that corresponding manner can be to receive extraneous Indication message, can be also that directly configuration is corresponding regular in base station; or be defaulted as employing a certain mode wherein and carry out work, such variation does not affect protection scope of the present invention.
Mode one, the base station value by DAI is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, and indicates identical PUCCH format 3 channel resources to terminal equipment with the ACK/NACK resource indication territory in the PDCCH of PDSCH transmission on corresponding descending auxiliary carrier wave.
Under this kind of mode, one (PUCCH format 3 single port transmission)/mono-group of (PUCCH format 3 multiport transmission) PUCCH format 3 channel resource only need to be determined in base station, and the value of the DAI sending in all base stations is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, and in the ACK/NACK resource indication territory in the PDCCH of PDSCH transmission on corresponding descending auxiliary carrier wave indication to terminal equipment.
Mode two, the base station value by DAI is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, and indicates different PUCCH format 3 channel resources to terminal equipment from the ACK/NACK resource indication territory in the PDCCH of PDSCH transmission on corresponding descending auxiliary carrier wave.
Under this kind of mode, two (PUCCH format 3 single port transmission)/two groups of (PUCCH format 3 multiport transmission) PUCCH format 3 channel resources need to be determined in base station, and the value of the DAI sending in base station be greater than in the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge in ACK/NACK resource indication territory indication to terminal equipment one of them/mono-group of PUCCH format 3 channel resource, in ACK/NACK resource indication territory on the descending auxiliary carrier wave of correspondence in the PDCCH of PDSCH transmission indication to terminal equipment another/mono-group of PUCCH format 3 channel resource.
The ACK/NACK feedback information that step S403, base station adopt PUCCH format 3 scheme receiving terminal apparatus to send according to determined PUCCH format 3 channel resources.
It is pointed out that owing to there being the send mode of two kinds of information contents in step S402, so corresponding, in this step, same corresponding different send mode, exists different processing procedures.
Mode one in corresponding step S402, in this step, specifically PUCCH format 3 channel resources by the ACK/NACK resource indication territory indication in the PDCCH of which kind of type carry out the reception of ACK/NACK feedback information, need to determine according to corresponding information transmission situation, according to different information, send situation, the processing procedure in this step is described as follows.
Scene one, base station have only sent to terminal equipment the PDCCH that PDSCH and/or indicating downlink SPS resource discharge on downlink main carrier to carry, and the value that has sent DAI is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge.
Base station adopts PUCCH format 3 schemes, in the value by DAI, be greater than on information configuration in the ACK/NACK resource indication territory in the arbitrary PDCCH in the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge PUCCH format 3 channel resources to terminal equipment the ACK/NACK feedback information that receiving terminal apparatus sends.
Under this kind of scene, if base station on determined PUCCH format 3 channel resources, does not receive the ACK/NACK feedback information that terminal equipment sends, the corresponding processing procedure in base station comprises following two kinds of modes:
(1) value that judgement terminal equipment in base station has been lost all DAI is greater than the transfer of data (comprising the PDCCH transmission that PDSCH transmission and indicating downlink SPS resource discharge) on the downlink main carrier to carry that 1 PDCCH is corresponding, all data on base station re-transmission downlink main carrier to carry.
(2) value that judgement terminal equipment in base station has been lost all DAI is greater than the transfer of data (comprising that the PDCCH that PDSCH transmission and indicating downlink SPS resource discharge transmits) on the downlink main carrier to carry that 1 PDCCH is corresponding, further, ACK/NACK feedback information is detected in base station on PUCCH format 1a/1b channel resource.
If ACK/NACK detected, according to this feedback information, determine that DAI value on downlink main carrier to carry equals the re-transmission of SPS PDSCH on the re-transmission of the data that 1 PDCCH is corresponding and/or downlink main carrier to carry, lays equal stress on and passes data corresponding to PDCCH that on downlink main carrier to carry, all DAI values are greater than 1; If ACK/NACK do not detected, judgement terminal equipment in base station is lost all data (being DTX), and base station retransmits all data on downlink main carrier to carry.
Concrete employing can be determined which kind of above-mentioned mode according to actual needs.
Scene two, base station have only sent PDSCH to terminal equipment on descending auxiliary carrier wave.
Base station adopts PUCCH format 3 schemes, information configuration in ACK/NACK resource indication territory in arbitrary PDCCH on by corresponding descending auxiliary carrier wave in the PDCCH of PDSCH transmission to terminal equipment PUCCH format 3 channel resources on, the ACK/NACK feedback information that receiving terminal apparatus sends.
Under this kind of scene, if base station on determined PUCCH format 3 channel resources, does not receive the ACK/NACK feedback information that terminal equipment sends, the corresponding processing procedure in base station is as follows:
Base station judgement terminal equipment has been lost the transfer of data on all descending auxiliary carrier waves, and base station retransmits all data on descending auxiliary carrier wave.
Scene three, base station have sent the PDCCH of PDSCH and/or the release of indicating downlink SPS resource on downlink main carrier to carry to terminal equipment, the value that has sent DAI is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, and, on descending auxiliary carrier wave, to terminal equipment, sent PDSCH.
Base station adopts PUCCH format 3 schemes, in the value by DAI, be greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, and on PUCCH format 3 channel resources of the information configuration in the ACK/NACK resource indication territory in any one PDCCH in the PDCCH of PDSCH transmission on corresponding descending auxiliary carrier wave to terminal equipment, the ACK/NACK feedback information that receiving terminal apparatus sends.
Under this kind of scene, if base station on determined PUCCH format 3 channel resources, does not receive the ACK/NACK feedback information that terminal equipment sends, the corresponding processing procedure in base station comprises following two kinds of modes:
(1) value that judgement terminal equipment in base station has been lost all DAI on downlink main carrier to carry be greater than 1 downlink main carrier to carry corresponding to PDCCH on transfer of data (comprising that the PDCCH that PDSCH transmission and indicating downlink SPS resource discharge transmits), and the PDCCH of PDSCH transmission on all descending auxiliary carrier waves, base station retransmits all data on downlink main carrier to carry and descending auxiliary carrier wave.
(2) value that judgement terminal equipment in base station has been lost all DAI is greater than the transfer of data (comprising that the PDCCH that PDSCH transmission and indicating downlink SPS resource discharge transmits) on the downlink main carrier to carry that 1 PDCCH is corresponding, and the PDCCH of PDSCH transmission on all descending auxiliary carrier waves, further, ACK/NACK feedback information is detected in base station on PUCCH format 1a/1b channel resource.
If base station detects ACK/NACK feedback information, base station determines that according to ACK/NACK feedback information the value of the DAI on downlink main carrier to carry equals the re-transmission of SPS PDSCH on the re-transmission of the data that 1 PDCCH is corresponding and/or downlink main carrier to carry, and the value that passes all DAI on downlink main carrier to carry of laying equal stress on is greater than 1 corresponding data of PDCCH and all data on descending auxiliary carrier wave;
If base station does not detect ACK/NACK feedback information, base station determines that terminal equipment lost all data, and base station retransmits all data that send to terminal equipment.
Above-mentioned that scene no matter, in the situation that the mode one of corresponding step S402, base station all can determine that the ACK/NACK feedback information that terminal equipment sends is to determine according to the transmission mode of the descending carrier of the descending carrier of terminal equipment configuration and each configuration.
In actual application scenarios, specifically adopt which kind of above-mentioned mode to determine according to actual needs, such variation does not affect protection scope of the present invention.
On the other hand, mode two in corresponding step S402, in this step, specifically PUCCH format 3 channel resources by the ACK/NACK resource indication territory indication in which class PDCCH carry out the reception of ACK/NACK feedback information, need to determine according to corresponding information transmission situation, according to different information, send situation, the processing procedure in this step is described as follows.
Scene one, base station have only sent to terminal equipment the PDCCH that PDSCH and/or indicating downlink SPS resource discharge on downlink main carrier to carry, and the value that has sent DAI is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge.
Base station adopts PUCCH format 3 schemes, the value by DAI be greater than information configuration in the ACK/NACK resource indication territory of the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge to terminal equipment PUCCH format 3 channel resources on, the ACK/NACK feedback information that receiving terminal apparatus sends.
Under this kind of scene, base station determines that the ACK/NACK feedback information that terminal equipment sends is according to the ACK/NACK feedback information of the definite downlink main carrier to carry of the transmission mode of downlink main carrier to carry.
Further, for this kind of scene, if base station on determined PUCCH format 3 channel resources, does not receive the ACK/NACK feedback information that terminal equipment sends, the corresponding processing procedure in base station comprises following two kinds of modes:
(1) value that judgement terminal equipment in base station has been lost all DAI is greater than the transfer of data (comprising the PDCCH transmission that PDSCH transmission and indicating downlink SPS resource discharge) on the downlink main carrier to carry that 1 PDCCH is corresponding, all data on base station re-transmission downlink main carrier to carry.
(2) value that judgement terminal equipment in base station has been lost all DAI is greater than the transfer of data (comprising that the PDCCH that PDSCH transmission and indicating downlink SPS resource discharge transmits) on the downlink main carrier to carry that 1 PDCCH is corresponding, further, ACK/NACK feedback information is detected in base station on PUCCH format 1a/1b channel resource.
If base station detects ACK/NACK feedback information, base station determines that according to ACK/NACK feedback information the value of the DAI on downlink main carrier to carry equals the re-transmission of SPS PDSCH on the re-transmission of the data that 1 PDCCH is corresponding and/or downlink main carrier to carry, lays equal stress on and passes the corresponding data of PDCCH that the value of all DAI on downlink main carrier to carry is greater than 1.
If base station does not detect ACK/NACK feedback information, base station determines that terminal equipment lost all data, and base station retransmits all data that send to terminal equipment.
Scene two, base station have sent PDSCH to terminal equipment on descending auxiliary carrier wave.
Base station adopts PUCCH format 3 schemes, on corresponding PUCCH format 3 channel resources of information on by corresponding descending auxiliary carrier wave in the ACK/NACK resource indication territory of the PDCCH of PDSCH transmission, the ACK/NACK feedback information that receiving terminal apparatus sends.
Under this kind of scene, base station determines that the ACK/NACK feedback information that terminal equipment sends is to determine according to the transmission mode of the descending carrier of the descending carrier of terminal equipment configuration and each configuration.
Further, for this kind of scene, if base station on determined PUCCH format 3 channel resources, does not receive the ACK/NACK feedback information that terminal equipment sends, the corresponding processing procedure in base station comprises following two kinds of modes:
(1) transfer of data that judgement terminal equipment in base station has been lost all descending auxiliary carrier waves, base station retransmits all data on descending auxiliary carrier wave.
(2) transfer of data that judgement terminal equipment in base station has been lost all descending auxiliary carrier waves, base station retransmits all data on descending auxiliary carrier wave, if base station has sent the PDCCH of PDSCH and/or the release of indicating downlink SPS resource on downlink main carrier to carry to terminal equipment simultaneously, and the value that has sent DAI is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, further, PUCCH format 3 schemes can be continued to adopt in base station, in the value by DAI, be greater than on information configuration in the ACK/NACK resource indication territory of the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge PUCCH format 3 channel resources to terminal equipment, the ACK/NACK feedback information that receiving terminal apparatus sends.
If base station receives the ACK/NACK feedback information that terminal equipment sends on these PUCCH format 3 channel resources, the feedback information that this ACK/NACK feedback information is data on downlink main carrier to carry is determined in base station, and according to this ACK/NACK feedback information, determine the re-transmission of data on downlink main carrier to carry, lay equal stress on and descend all data on the auxiliary carrier wave of row.
If base station does not receive the ACK/NACK feedback information that terminal equipment sends on PUCCH format 3 channel resources, the value that judgement terminal equipment in base station has been lost all DAI is equally greater than transfer of data on the downlink main carrier to carry that 1 PDCCH is corresponding (comprising that the PDCCH that on downlink main carrier to carry, PDSCH transmission and indicating downlink SPS resource discharge transmits), base station retransmits all data on downlink main carrier to carry and descending auxiliary carrier wave, or ACK/NACK feedback information can further be detected in base station on PUCCH format 1a/1b channel resource.
Further, detect the situation of ACK/NACK feedback information for base station on PUCCH format 1a/1b channel resource, corresponding processing procedure is as follows:
If base station detects ACK/NACK feedback information, base station determines that according to ACK/NACK feedback information the value of the DAI on downlink main carrier to carry equals the re-transmission of SPS PDSCH on the re-transmission of the data that 1 PDCCH is corresponding and/or downlink main carrier to carry, and the value that passes all DAI on downlink main carrier to carry of laying equal stress on is greater than data (comprising that the PDCCH that PDSCH transmission and indicating downlink SPS resource discharge transmits) on 1 the corresponding downlink main carrier to carry of PDCCH and all data on descending auxiliary carrier wave;
If base station does not detect ACK/NACK feedback information, base station determines that terminal equipment lost all data, and base station retransmits all data that send to terminal equipment.
It is to be noted, for the various situations in the mode two in corresponding step S402, in order to guarantee in the situation that there is a plurality of descending carrier, terminal equipment can be determined PUCCH format 3 channel resources according to the information in the ACK/NACK resource indication territory of the PDCCH of respective type, can not produce major gap of understanding because of the information gap in a plurality of PDCCH of same kind, so, need to carry out following setting.
It is identical that the value of a plurality of DAI that A, base station send to terminal equipment is greater than PUCCH format 3 channel resources indicated in the ACK/NACK resource indication territory in the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge.
PUCCH format 3 channel resources indicated in ACK/NACK resource indication territory on the descending auxiliary carrier wave of a plurality of correspondences that B, base station send to terminal equipment in the PDCCH of PDSCH transmission are identical.
It is pointed out that when PUCCH format 3 is single port transmission mode, in above-mentioned two situations a resource in corresponding high-rise pre-configured a plurality of PUCCH format 3 channel resources of the indicated value in the indication of the resource in PDCCH territory; When PUCCH format3 is multiport (2 port) transmission mode, while being SORTD pattern, the value of DAI is greater than one group of resource in corresponding high-rise pre-configured many groups PUCCH format 3 channel resources of indicated value in the resource indication territory in the PDCCH of PDSCH transmission on PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge and corresponding descending auxiliary carrier wave, every group of resource comprises 2 PUCCH format 3 channel resources, respectively corresponding different antenna ports.
It is pointed out that ACK/NACK resource in above-mentioned PDCCH indication territory can be the reusing of existing bit field in PDCCH, for example, reuse 2 bit TPC indication territories, or the bit field for newly increasing in PDCCH.
Compared with prior art, the embodiment of the present invention has the following advantages:
By the technical scheme of the application embodiment of the present invention, can realize value by DAI and be greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, and information indication PUCCH format 3 channel resources in the ACK/NACK resource indication territory in the PDCCH of PDSCH transmission on corresponding descending auxiliary carrier wave, made to configure the terminal equipment of a plurality of descending carriers when only receiving data on downlink main carrier to carry, can adopt equally PUCCH format 3 scheme transferring ACK/NACK feedback informations, thereby, avoid base station and terminal equipment to cause for the understanding differently of transmission plan of ACK/NACK feedback information, improve reliability and the efficiency of ACK/NACK transmission of feedback information.
Below, in conjunction with concrete application scenarios, the technical scheme that the embodiment of the present invention is proposed describes.
In LTE-A TDD system, for the technical scheme to above-mentioned illustrates more clearly, for the processing procedure of terminal equipment side, two kinds of modes in corresponding step S302 are respectively illustrated respectively.
Identical PUCCH format 3 channel resources are indicated in the ACK/NACK resource indication territory that the value of mode one, DAI is greater than in the PDCCH of PDSCH transmission on PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge and corresponding descending auxiliary carrier wave.
As shown in Figure 5, the schematic flow sheet of the transmission method of the ACK/NACK feedback information under a kind of concrete application scenarios proposing for the embodiment of the present invention, the method specifically comprises the following steps:
Step S501, the UE that has configured a plurality of descending carriers receive data on N descending carrier, a M descending sub frame.
M is descending sub frame number corresponding to sub-frame of uplink that UE carries out ACK/NACK feedback, as shown in table 1, N >=1,1≤M≤4.
The information that step S502, UE are greater than according to the value of the DAI that receives in the ACK/NACK resource indication territory in the arbitrary PDCCH in the PDCCH of PDSCH transmission on PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge and/or corresponding descending auxiliary carrier wave is determined PUCCH format 3 channel resources.
In actual application scenarios, may there is different reception scenes in UE, corresponding, and the corresponding processing procedure that UE determines according to the actual situation that receives information is as follows.
When UE only receives the PDCCH of PDSCH and/or the release of indicating downlink SPS resource at downlink main carrier to carry, and when the value that receives DAI is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, the information that UE is greater than according to the value of DAI in the ACK/NACK resource indication territory in the arbitrary PDCCH in the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge is determined PUCCH format 3 channel resources.
When UE when descending auxiliary carrier wave receives PDSCH, UE determines PUCCH format 3 channel resources according to the information in the ACK/NACK resource indication territory in arbitrary PDCCH in the PDCCH of PDSCH transmission on the descending auxiliary carrier wave of correspondence.
When value that UE receives PDCCH that PDSCH and/or indicating downlink SPS resource discharge and DAI at downlink main carrier to carry is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, and when descending auxiliary carrier wave receives PDSCH, the information that UE is greater than according to the value of DAI in the ACK/NACK resource indication territory in the arbitrary PDCCH in the PDCCH of PDSCH transmission on PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge and corresponding descending auxiliary carrier wave is determined PUCCH format 3 channel resources.
Step S503, UE determine ACK/NACK feedback information according to the transmission mode of the descending carrier of the descending carrier of configuration and each configuration.
Step S504, UE, on determined PUCCH format 3 channel resources, adopt PUCCH format 3 scheme transferring ACK/NACK feedback informations.
It should be noted that, determined PUCCH format 3 channel resources of information that UE is greater than in the ACK/NACK resource indication territory in the arbitrary PDCCH in the PDCCH of PDSCH transmission on PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge and/or corresponding descending auxiliary carrier wave according to the value of the DAI that receives in step S502 are same/mono-group channel resource, therefore above-mentioned 3 kinds of reception conditions can be merged into a kind of UE behavior, when UE only receives the PDCCH of PDSCH and/or the release of indicating downlink SPS resource at downlink main carrier to carry, and when the value that receives DAI is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, or when UE is when descending auxiliary carrier wave receives PDSCH, the information that UE is greater than according to the value of DAI in the ACK/NACK resource indication territory in the arbitrary PDCCH in the PDCCH of PDSCH transmission on PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge and corresponding descending auxiliary carrier wave is determined PUCCH format 3 channel resources, then perform step S503 and step S504.
For the setting of this situation, in order to guarantee the consistency of processing rule, need to carry out following setting.
When the value of the DAI that UE receives is greater than PUCCH format 3 channel resources of the ACK/NACK resource indication territory indication of the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, PUCCH format 3 channel resources of the ACK/NACK resource indication territory indication on the corresponding descending auxiliary carrier wave receiving with UE in the PDCCH of PDSCH transmission are when inconsistent, the corresponding following two kinds of situations that comprise of processing:
(1) UE can think to dispatch mistake, transferring ACK/NACK feedback information not in current sub-frame of uplink.
(2) UE selects one of them PUCCH format 3 channel resource transferring ACK/NACK feedback information.
In addition, PUCCH format 3 channel resources of ACK/NACK resource indication territory indication that are greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge when the value of a plurality of DAI that UE receives are inconsistent, or PUCCH format 3 channel resources of the indication of the ACK/NACK resource on the descending auxiliary carrier wave of a plurality of correspondences that UE receives in the PDCCH of PDSCH transmission territory indication are when inconsistent, UE also can think to dispatch mistake, transferring ACK/NACK feedback information not in current sub-frame of uplink, or select one of them PUCCH format 3 channel resource transferring ACK/NACK feedback information.
In actual application scenarios, can adopt above-mentioned any situation to process, such variation does not affect protection scope of the present invention.
Different PUCCH format 3 channel resources are indicated in the ACK/NACK resource indication territory that the value of mode two, DAI is greater than in the PDCCH of PDSCH transmission on PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge and corresponding descending auxiliary carrier wave.
As shown in Figure 6, the schematic flow sheet of the transmission method of the ACK/NACK feedback information under a kind of concrete application scenarios proposing for the embodiment of the present invention, the method specifically comprises the following steps:
Step S601, the UE that has configured a plurality of descending carriers receive data on N descending carrier, a M descending sub frame.
M is descending sub frame number corresponding to sub-frame of uplink that UE carries out ACK/NACK feedback, as shown in table 1, N >=1,1≤M≤4.
Step S602, UE determine corresponding processing procedure according to the actual situation that receives information.
When UE only receives at downlink main carrier to carry the PDCCH that PDSCH and/or indicating downlink SPS resource discharge, and the value that receives DAI is while being greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, execution step S603;
When UE is when descending auxiliary carrier wave receives PDSCH, execution step S605.
It is pointed out that the situation that above-mentioned UE receives data at descending auxiliary carrier wave comprises following two kinds:
(1) UE only receives PDSCH at descending auxiliary carrier wave.
(2) value that UE receives PDCCH that PDSCH and/or indicating downlink SPS resource discharge and DAI at downlink main carrier to carry is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, and receives PDSCH at descending auxiliary carrier wave.
The information that step S603, UE are greater than according to the value of DAI in the ACK/NACK resource indication territory of the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge is determined PUCCH format 3 channel resources.
Step S604, UE, according to the transmission mode of downlink main carrier to carry, only produce ACK/NACK feedback information to downlink main carrier to carry.
In concrete application scenarios, in said process, UE does not need the ACK/NACK feedback information of the many code words in same descending sub frame to carry out space merging.
After the processing procedure of this step completes, execution step S607.
Step S605, UE determine PUCCH format 3 channel resources according to the information in the ACK/NACK resource indication territory of the PDCCH of PDSCH transmission on the descending auxiliary carrier wave of correspondence.
Step S606, UE determine ACK/NACK feedback information according to the transmission mode of the descending carrier of the descending carrier of configuration and each configuration.
After the processing procedure of this step completes, execution step S607.
Step S607, UE on determined PUCCH format 3 channel resources, adopt PUCCH format 3 scheme transferring ACK/NACK feedback informations in step S603 or step S605.
For convenience of description, in above-mentioned step S603, determined PUCCH format 3 channel resources are designated as PUCCH format 3 channel resources 1, and in step S605, determined PUCCH format 3 channel resources are designated as PUCCH format 3 channel resources 2.
, in actual application scenarios, owing to having set the ACK/NACK resource of two class PDCCH in the manner, indicate the information in territory obstructed, so PUCCH format 3 channel resources 2 are different from PUCCH format 3 channel resources 1.
On the other hand, in order to guarantee in the situation that there is a plurality of descending carrier, UE can determine PUCCH format 3 channel resources according to the information in the ACK/NACK resource indication territory of the PDCCH of respective type, can not produce major gap of understanding because of the information gap in a plurality of PDCCH of same kind, so, need to arrange as follows.
The value of a plurality of DAI is greater than PUCCH format 3 channel resources of the resource indication territory indication of the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge should be identical; PUCCH format 3 channel resources of the resource indication territory indication on the descending auxiliary carrier wave of a plurality of correspondences in the PDCCH of PDSCH transmission should be identical.
Otherwise UE can think to dispatch mistake, transferring ACK/NACK feedback information not in current sub-frame of uplink; Or UE selects one of them PUCCH format 3 channel resource transferring ACK/NACK feedback information.
In actual application scenarios, no matter for the method in which kind of above-mentioned situation, mentioned ACK/NACK resource indication territory is the reusing of existing bit field in PDCCH, for example, reuse 2 bit TPC indication territories, or the bit field for newly increasing in PDCCH.
Especially, for above-mentioned step S501 to step S504, or step S601 is to the described method of step S607, when in carrier wave reconfiguration course, can only there is a transfer of data (comprising the PDCCH that dynamic PDSCH, SPS PDSCH and indication SPS resource discharge) at the most at downlink main carrier to carry in base station, to avoid UE to determine according to the descending carrier of configuration that base station that ACK/NACK feedback bits causes and UE understand differently, cause problem; If now UE receives data, can the PUCCH format 1a/1b channel resource definite at the minimum CCE of PDCCH corresponding to these data on or on the pre-configured PUCCH format 1a/1b channel resource of high level corresponding to SPS PDSCH, (by the 2 bit TPC that activate in the PDCCH of this SPS PDSCH, indicate) 1 or 2 bit ACK/nack message of the packet that transmission receives; Base station only need receive data in above-mentioned PUCCH format 1a/1b resource, does not exist and understands ambiguity.
On the other hand, for the processing procedure of base station side, two kinds of send modes in corresponding step S402 are respectively illustrated respectively.
Identical PUCCH format 3 channel resources are indicated in the ACK/NACK resource indication territory that mode one in corresponding step S402, the value of DAI are greater than in the PDCCH of PDSCH transmission on PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge and corresponding descending auxiliary carrier wave.
As shown in Figure 7, the schematic flow sheet of the transmission method of the ACK/NACK feedback information under a kind of concrete application scenarios proposing for the embodiment of the present invention, the method specifically comprises the following steps:
Step S701, base station determine that configuration is to PUCCH format 3 channel resources that configured the UE of a plurality of descending carriers.
When PUCCH format 3 transmits for single port, PUCCH format 3 channel resources are determined in base station, when PUCCH format 3 is multiport (2 port) transmission, one group of PUCCH format 3 channel resource is determined in base station, comprise 2 PUCCH format 3 channel resources, respectively corresponding different port.
Step S702, base station send to UE by configured PUCCH format 3 channel resources by the ACK/NACK resource indication territory in PDCCH.
Wherein, PDCCH comprises that the value of DAI is greater than that PDCCH(that on 1 corresponding downlink main carrier to carry, PDSCH transmission and indicating downlink SPS resource discharge comprises that dynamic transfer, indication SPS PDSCH activate and the PDCCH of SPS resource release), any one or more PDCCH in the PDCCH corresponding with PDSCH with transmitting on descending auxiliary carrier wave.
According to the situation of the actual transmission information in base station, base station indicates the processing procedure of PUCCH format 3 channel resources as follows by PDCCH.
When base station has only sent the PDCCH that PDSCH and/or indicating downlink SPS resource discharge on downlink main carrier to carry, and when the value that has sent DAI is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, the information that base station is greater than the value of DAI in the ACK/NACK resource indication territory in the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge is designated as PUCCH format 3 channel resources definite in step S701, and sends to UE.
When only there is PDSCH transmission in base station on descending auxiliary carrier wave, base station is designated as PUCCH format 3 channel resources definite in step S701 by the information in the ACK/NACK resource indication territory in the PDCCH of PDSCH transmission on the descending auxiliary carrier wave of correspondence, and sends to UE;
When base station has sent the PDCCH that PDSCH and/or indicating downlink SPS resource discharge on downlink main carrier to carry, and the value that has sent DAI is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, and while there is PDSCH transmission on descending auxiliary carrier wave, the information that base station is greater than the value of DAI in the ACK/NACK resource indication territory in the PDCCH of PDSCH transmission on PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge and corresponding descending auxiliary carrier wave is designated as PUCCH format 3 channel resources definite in step S701, and send to UE.
Step S703, base station determine that the ACK/NACK feedback information of UE transmission is definite according to the transmission mode of the descending carrier of the descending carrier of configuration and each configuration.
Step S704, base station adopt PUCCH format 3 schemes to receive ACK/NACK feedback information on definite PUCCH format 3 channel resources.
In actual application scenarios, owing to having set the ACK/NACK resource of two kinds of PDCCH in this situation, indicate the information in territory identical, so PUCCH format 3 channel resources of indicating in the PDCCH of base station in above-mentioned arbitrary step all should be identical.
On the other hand, in order to guarantee to exist in a plurality of PDCCH situations, UE can correctly determine PUCCH format 3 channel resources according to the information in the ACK/NACK resource indication territory of PDCCH, the information gap in can a plurality of PDCCH and produce major gap of understanding, so, need to arrange as follows:
The value of a plurality of DAI that base station sends is greater than PUCCH format 3 channel resources of the resource indication territory indication of the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge should be identical; PUCCH format 3 channel resources of the resource indication territory indication on the descending auxiliary carrier wave of a plurality of correspondences that base station sends in the PDCCH of PDSCH transmission should be identical.
In this step, if base station does not receive ACK/NACK feedback information on above-mentioned PUCCH format 3 channel resources, three kinds of situations in corresponding step S702, the further reception & disposal process in base station is as follows:
(1) when base station is only when downlink main carrier to carry has sent the PDCCH that PDSCH and/or indicating downlink SPS resource discharge, corresponding processing mode comprises:
The value that mode one, base station judgement UE has lost all DAI is greater than the transfer of data (comprising the PDCCH transmission that PDSCH transmission and/or indicating downlink SPS resource discharge) on the downlink main carrier to carry that 1 PDCCH is corresponding, and base station retransmits all data on downlink main carrier to carry.
The value that mode two, base station judgement UE has lost all DAI is greater than the transfer of data (comprising the PDCCH transmission that PDSCH transmission and/or indicating downlink SPS resource discharge) on the downlink main carrier to carry that 1 PDCCH is corresponding, and ACK/NACK feedback information is further detected in base station on PUCCH format 1a/1b channel resource.
If ACK/NACK feedback information detected, according to this feedback information, determine that the value of DAI on downlink main carrier to carry equals the re-transmission of SPS PDSCH on the re-transmission of the data that 1 PDCCH is corresponding and/or downlink main carrier to carry, the value that passes all DAI on downlink main carrier to carry of laying equal stress on is greater than the data (comprising the PDCCH transmission that PDSCH transmission and/or indicating downlink SPS resource discharge) on the downlink main carrier to carry that 1 PDCCH is corresponding.
If ACK/NACK do not detected, judgement UE in base station loses all data (being DTX), and base station retransmits all data.
(2) when base station only exists PDSCH transmission on descending auxiliary carrier wave, base station judgement UE has lost the PDSCH transmission on the descending auxiliary carrier wave of all correspondences, and base station retransmits all data on descending auxiliary carrier wave.
(3) when base station, on downlink main carrier to carry, sent the PDCCH of PDSCH and/or the release of indicating downlink SPS resource, and the value that has sent DAI is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, and while there is PDSCH transmission on descending auxiliary carrier wave, corresponding processing mode comprises:
The value that mode one, base station judgement UE has lost PDSCH transmission on the descending auxiliary carrier wave of all correspondences and DAI is greater than the transfer of data (comprising the PDCCH that PDSCH transmission and/or indicating downlink SPS resource discharge) on the downlink main carrier to carry that 1 PDCCH is corresponding, and base station retransmits all data.
The value that mode two, base station judgement UE has lost PDSCH transmission on the descending auxiliary carrier wave of all correspondences and DAI is greater than the transfer of data (comprising the PDCCH that PDSCH transmission and/or indicating downlink SPS resource discharge) on the downlink main carrier to carry that 1 PDCCH is corresponding, and ACK/NACK feedback information is further detected in base station on PUCCH format 1a/1b channel resource.
If ACK/NACK feedback information detected, according to this feedback information, determine that the value of DAI on downlink main carrier to carry equals the re-transmission of SPS PDSCH on the re-transmission of the data that 1 PDCCH is corresponding and/or downlink main carrier to carry, and retransmit every other data.
If ACK/NACK do not detected, judgement UE in base station loses all data (being DTX), and base station retransmits all data.
Different PUCCH format 3 channel resources are indicated in the ACK/NACK resource indication territory that mode two in corresponding step S402, the value of DAI are greater than in the PDCCH of PDSCH transmission on PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge and corresponding descending auxiliary carrier wave.
As shown in Figure 8, the schematic flow sheet of the transmission method of the ACK/NACK feedback information under a kind of concrete application scenarios proposing for the embodiment of the present invention, the method specifically comprises the following steps:
Step S801, base station determine that configuration is to PUCCH format 3 channel resources that configured the UE of a plurality of descending carriers.
When PUCCH format 3 transmits for single port, 2 PUCCH format 3 channel resources are determined in base station, when PUCCH format 3 is multiport (2 port) transmission, 2 groups of PUCCH format 3 channel resources are determined in base station, every group comprises 2 PUCCH format 3 channel resources, respectively corresponding different port.Being called for short above-mentioned 2/2 groups channel resources is PUCCH format 3 channel resources 1 and PUCCH format 3 channel resources 2.
Step S802, base station send to UE by configured PUCCH format 3 channel resources by the ACK/NACK resource indication territory in PDCCH.
Wherein, PDCCH comprises 2 classes, one class is that the value of DAI is greater than the PDCCH(that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge and comprises dynamic transfer, the PDCCH that indication SPS PDSCH activates and SPS resource discharges), another kind of is the PDCCH corresponding with the PDSCH transmitting on descending auxiliary carrier wave.2/2 groups PUCCH format 3 channel resources of determining in step S801 are indicated respectively in ACK/NACK resource indication territory in above-mentioned two class PDCCH.
The situation that step S803, base station send information according to reality is determined corresponding processing procedure.
When base station only exists transfer of data on downlink main carrier to carry, and the value that has sent DAI is while being greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, execution step S804 and S805;
When there is transfer of data in base station on descending auxiliary carrier wave, execution step S806 and S807.
It is pointed out that above-mentioned base station exists the situation of transfer of data to comprise following two kinds on descending auxiliary carrier wave:
(1) only there is PDSCH transmission in base station on descending auxiliary carrier wave.
(2) base station has sent the PDCCH of PDSCH and/or the release of indicating downlink SPS resource on downlink main carrier to carry, and the value that has sent DAI is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, and on descending auxiliary carrier wave, there is PDSCH transmission.
Step S804, base station determine that the ACK/NACK feedback information of UE transmission is the ACK/NACK feedback information that descending master is carried.
In this kind of application scenarios, UE can not carry out space merging to the ACK/NACK feedback information of the many code words in same descending sub frame.
Step S805, base station adopt PUCCH format 3 schemes to receive ACK/NACK feedback informations on the value by DAI is greater than PUCCH format 3 channel resources of the information indication in the ACK/NACK resource indication territory of the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge.
Step S806, base station determine that the ACK/NACK feedback information of UE transmission is for determining according to the transmission mode of the descending carrier of the descending carrier of configuration and each configuration.
On PUCCH format 3 channel resources of the information indication in the ACK/NACK resource indication territory of the PDCCH of step S807, base station PDSCH transmission on the descending auxiliary carrier wave by correspondence, adopt PUCCH format 3 schemes to receive ACK/NACK feedback information.
For convenience of description, in above-mentioned step S805, determined PUCCH format 3 channel resources are designated as PUCCH format 3 channel resources 1, and in step S807, determined PUCCH format 3 channel resources are designated as PUCCH format 3 channel resources 2.
In actual application scenarios, owing to having set the information difference in the ACK/NACK resource indication territory of two kinds of PDCCH in the manner, so PUCCH format 3 channel resources 2 are different from PUCCH format 3 channel resources 1.
On the other hand, in order to guarantee in the situation that there is a plurality of descending carrier, UE can determine PUCCH format 3 channel resources according to the information in the ACK/NACK resource indication territory of the PDCCH of respective type, can not produce major gap of understanding because of the information gap in a plurality of PDCCH of same kind, so, need to arrange as follows.
The value of a plurality of DAI that base station sends is greater than PUCCH format 3 channel resources of the resource indication territory indication of the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge should be identical; PUCCH format 3 channel resources of the resource indication territory indication on the descending auxiliary carrier wave of a plurality of correspondences that base station sends in the PDCCH of PDSCH transmission should be identical.
Further, in step S805, if base station does not receive ACK/NACK feedback information on above-mentioned PUCCH format 3 channel resources 1, the further processing procedure in base station is as follows:
Now base station has only sent the PDCCH of PDSCH and/or the release of indicating downlink SPS resource at downlink main carrier to carry, and corresponding processing mode comprises:
The value that mode one, base station judgement UE has lost all DAI is greater than the transfer of data (comprising the PDCCH that PDSCH transmission and/or indicating downlink SPS resource discharge) on 1 downlink main carrier to carry, and base station retransmits all data on downlink main carrier to carry.
The value that mode two, base station judgement UE has lost all DAI is greater than the transfer of data (comprising the PDCCH that PDSCH transmission and/or indicating downlink SPS resource discharge) on 1 downlink main carrier to carry, and ACK/NACK feedback information is further detected in base station on PUCCH format 1a/1b channel resource.
If ACK/NACK feedback information detected, according to this feedback information, determine that the value of DAI on downlink main carrier to carry equals the re-transmission of SPS PDSCH on the re-transmission of the data that 1 PDCCH is corresponding and/or downlink main carrier to carry, lay equal stress on and pass data (comprising the PDCCH that PDSCH transmission and/or indicating downlink SPS resource discharge) corresponding to PDCCH that the value of all DAI on downlink main carrier to carry is greater than 1.
If ACK/NACK do not detected, judgement UE in base station loses all data (being DTX), and base station retransmits all data.
Further, in step S807, if base station does not receive ACK/NACK feedback information on above-mentioned PUCCH format 3 channel resources 2, according to the actual transmission situation of base station, the further processing procedure in base station is divided into following two kinds of situations:
(1) when base station only exists PDSCH transmission on descending auxiliary carrier wave, base station judgement UE has lost the PDSCH transmission on all descending auxiliary carrier waves, and base station retransmits all data.
(2) when base station, on downlink main carrier to carry, sent the PDCCH of PDSCH and/or the release of indicating downlink SPS resource, and the value that has sent DAI is greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge, and while there is transfer of data on descending auxiliary carrier wave, corresponding processing mode comprises:
The value that mode one, base station judgement UE has lost PDSCH transmission on all descending auxiliary carrier waves and corresponding DAI is greater than the transfer of data (comprising the PDCCH that PDSCH transmission and/or indicating downlink SPS resource discharge) on the downlink main carrier to carry of 1 PDCCH, and base station retransmits all data.
The value that mode two, base station judgement UE has lost PDSCH transmission on all descending auxiliary carrier waves and corresponding DAI is greater than the transfer of data (comprising the PDCCH that PDSCH transmission and/or indicating downlink SPS resource discharge) on the downlink main carrier to carry of 1 PDCCH, and ACK/NACK feedback information is further detected in base station on PUCCH format 3 channel resources 1.
If ACK/NACK feedback information detected, the feedback information that this ACK/NACK feedback information is data on downlink main carrier to carry is determined in base station, and determine the re-transmission of data on downlink main carrier to carry according to this ACK/NACK feedback information, and retransmit the data on all descending auxiliary carrier waves.
If ACK/NACK do not detected, base station further judges that value that UE has lost the DAI of transfer of data on all corresponding downlink main carrier to carry is greater than the data (comprising the PDCCH that PDSCH transmission and/or indicating downlink SPS resource discharge) on the downlink main carrier to carry that 1 PDCCH is corresponding, and base station retransmits all data.
The value that mode three, base station judgement UE has lost PDSCH transmission on all descending auxiliary carrier waves and corresponding DAI is greater than the transfer of data (comprising the PDCCH that PDSCH transmission and/or indicating downlink SPS resource discharge) on the downlink main carrier to carry of 1 PDCCH, and ACK/NACK feedback information is further detected in base station on PUCCH format 3 channel resources 1 and PUCCH format 1a/1b channel resource.
In this kind of mode, ACK/NACK feedback information is detected in base station first on PUCCH format 3 channel resources 1.
If ACK/NACK feedback information detected, the re-transmission of data on downlink main carrier to carry is determined in base station according to ACK/NACK feedback information, and retransmits the data on all descending auxiliary carrier waves.
If ACK/NACK do not detected, ACK/NACK feedback information is further detected in base station on PUCCH format 1a/1b channel resource.
If ACK/NACK detected, according to this feedback information, determine that the value of DAI on downlink main carrier to carry equals the re-transmission of SPS PDSCH on the re-transmission of the data that 1 PDCCH is corresponding and/or downlink main carrier to carry, and retransmit every other data; If ACK/NACK do not detected, judgement UE in base station loses all data (being DTX), and base station retransmits all data.
Especially, for above-mentioned step S701 to step S704, or step S801 is to the described method of step S807, when in carrier wave reconfiguration course, can only there is transfer of data at downlink main carrier to carry in base station, but can there is the transfer of data of a plurality of descending sub frames, to avoid UE and base station to cause problem to understanding differently of ACK/NACK feedback bits; Now, if UE only receives PDCCH or the SPS PDSCH of corresponding DAI=1 at downlink main carrier to carry, can the PUCCH format 1a/1b channel resource definite at the minimum CCE of PDCCH corresponding to these data on or on the pre-configured PUCCH format 1a/1b channel resource of high level corresponding to SPS PDSCH, (by the 2 bit TPC that activate in the PDCCH of this SPS PDSCH, indicate) 1 or 2 bit ACK/nack message of the packet that transmission receives; If UE has received the value of corresponding DAI and has been greater than the PDCCH that PDSCH transmission on 1 corresponding downlink main carrier to carry and/or indicating downlink SPS resource discharge on downlink main carrier to carry, on PUCCH format 3 channel resources 1 of resource indication territory indication that can be in this PDCCH, send the ACK/NACK feedback information of downlink main carrier to carry; Base station only needs, according to from the actual schedule situation on downlink main carrier to carry, to determine on above-mentioned PUCCH format 1a/1b resource or PUCCH format 3 channel resources and receive data, does not exist and understand ambiguity.
Need to further be pointed out that, technical scheme illustrated in each above-mentioned embodiment goes for other feedback informations equally, as CQI, PMI, RI information (if these feedback informations also support to adopt PUCCH format 3 schemes to transmit).
