Description

The channel resource defining method of ACK/NACK feedback information and equipment
Technical field
The present invention relates to communication technical field, particularly a kind of channel resource defining method of ACK/NACK feedback information and equipment.
Background technology
For long-term evolution multi-carrier system, for supporting the system bandwidth wider than LTE (Long Term Evolution, Long Term Evolution) system, such as 100MHz, a kind of may be the frequency spectrum directly distributing 100M bandwidth, as shown in Figure 1; One may be to distribute to some spectrum aggregatings of existing system, gather into large bandwidth supply long-term evolution multi-carrier system to use, now in system, up-downgoing carrier wave can asymmetricly configure, namely 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 (Long Term Evolution Advanced, senior Long Term Evolution) system determines to support that at most 5 carrier waves are polymerized at present, a LTE-A UE (User Equipment, subscriber equipment) need at the corresponding multiple descending carrier of same sub-frame of uplink internal feedback and descending sub frame ACK (Acknowledgement, positive acknowledgement)/NACK (Negative Acknowledgement, Negative Acknowledgement) feedback information.Determine in current lte-a system, the ACK/NACK information bit of UE feedback is determined based on the descending carrier of configuration and the transmission mode of each descending carrier, namely at FDD (Frequency Division Duplex, Frequency Division Duplexing (FDD)) in system, UE needs feedback at a sub-frame of uplink bit ACK/NACK, wherein C ifor the code word number (during single codeword transmission C=1, C=2 during many codeword transmission) of each descending carrier, the transmission mode (i.e. code word number) of different descending carrier can be different, and N is UE configurating downlink carrier number; In TDD (Time Division Duplex, time division duplex) system, UE needs feeding back ACK/NACK feedback at a sub-frame of uplink bit ACK/NACK, wherein M is the descending sub frame quantity that UE needs to carry out at same sub-frame of uplink ACK/NACK feedback, and for different uplink-downlink configuration and sub-frame of uplink, the value of M is different, i.e. the quantity of each hurdle K in table 1.Corresponding same sub-frame of uplink carries out multiple descending sub frames of ACK/NACK feedback, hereinafter referred to as " feedback window ".
Table 1Downlink association set index K:{k 0, k 1... k m-1for TDD
In lte-a system, determine can adopt PUCCH (Physical Uplink Control Channel for being no more than 4 bit ACK/nack message, Physical Uplink Control Channel) format 1b with channelselection transmission plan, the program is carried out Channel assignment transmission by UE at multiple channel resource and is distinguished different ACK/NACK feedback information states, wherein, ACK/NACK mapping form is just used to realize the mapping of ACK/NACK information to be feedback and actual channel transmission information (i.e. PUCCH format 1b QPSK modulate 4 constellation point) and transmission channel.For 2,3,4 bit ACK/NACK feedback information, need 2,3,4 PUCCH format 1a/1b uplink control channel resources respectively.
In LTE-A TDD system, because PUCCH Format 1b with channel selection transmission plan supports at most 4 bit ACK/NACK feedback, when UE needs the ACK/NACK bit number of feedback more than 4 in a sub-frame of uplink, need to carry out ACK/NACK information merging (bundling) to reduce the bit number of ACK/NACK feedback information.Merge between the descending carrier that UE can be configured ACK/NACK feedback information (merging also known as frequency domain), namely as shown in Figure 3, for the schematic diagram that TDD system ACK/NACK feedback information frequency domain merges, the ACK/NACK information of UE to the packet that the descending carrier of configuration each in current downlink subframe in feedback window receives merges, generate the ACK/NACK feedback information that 1 bit merges, if the descending carrier of configuration is many codeword transmission pattern, also need to merge the ACK/NACK feedback information of multiple code words that this descending carrier receives (to merge also known as space, spatial bundling).Feedback information state comprises ACK (the correct packet received), NACK (packet of garbled-reception) and DTX (packet lost or do not dispatch).For judging packet loss, 2 bit DAI (Downlink Assignment Index in LTE TDD system in DL grant, descending allocation index) can be used to represent the sum of the PDCCH that the PDCCH with corresponding PDSCH that the descending carrier that configures in the same descending sub frame in feedback window transmits and instruction semi-continuous scheduling (SPS, Semi-Persistent Scheduling) PDSCH discharges.
In merging process, if UE can judge in the current downlink subframe in feedback window, during the descending carrier of configuration is deposited, (loss of the PDSCH of PDCCH and the PDCCH scheduling of instruction semi-continuous scheduling release judges by DAI downlink data packet loss, the loss of SPS packet judges by SPS service period), or UE does not receive downlink data packet at the descending carrier of all configurations in current downlink subframe, then DTX is generated as the feedback information merged to this descending sub frame; If UE judges in the current downlink subframe in feedback window, there is not downlink data packet loss in the descending carrier of configuration, and the feedback information of at least one packet that the descending carrier of multiple configuration in this descending sub frame receives is NACK, then NACK is generated as the feedback information merged to this descending sub frame; If UE judges in the current downlink subframe in feedback window, there is not downlink data packet loss in the descending carrier of configuration, and the feedback information of all packets that the descending carrier configured in this descending sub frame receives is all ACK, then ACK is generated as the feedback information merged to this descending sub frame.
Like this when UE is configured to be operated in multiple descending carrier, can ensure that the ACK/NACK number of bits of feedback after merging is M, M≤4, wherein M is the descending sub frame quantity that UE needs to carry out at same sub-frame of uplink ACK/NACK feedback, is determined by the uplink-downlink configuration of TDD system and different sub-frame of uplink positions.
In lte-a system, on each up-link carrier, the reserved of implicit information channel resource is only reserved for the PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) on the descending carrier matched with it.So-called implicit information channel resource, it is exactly the reserved uplink control channel resource in the control information region of the descending carrier that on a up-link carrier, correspondence one is fixing, control information region wherein and CCE (Control Channel Element, control channel unit), UE is numbered by the minimum CCE of the descending control signaling (PDCCH) sent on this descending carrier, all can calculate the uplink control channel resource that acquisition one is available, referred to as " implicit information channel resource " or " dynamic channel resource ".In addition, downlink data transmission may be also the business not having corresponding PDCCH, i.e. SPS packet.Descending SPS transmission only occurs on downlink main carrier to carry, and the PDCCH being transmitted to activate by an instruction SPS triggers, and can transmit after triggering according to fixing cycle and resource distribution, until after receiving the PDCCH of instruction SPS transmission release, and this SPS end of transmission.Therefore, corresponding PDCCH is not had in transmitting procedure after SPS is triggered, therefore without implicit information channel resource, the channel resource corresponding to each SPS data packet transmission is all identical, is a semi-static channel resource indicated by the TPC territory in the PDCCH that instruction SPS transmission activates.If base station needs to change SPS transmission configuration, as changed transmission bandwidth etc., then can send the dynamic PDCCH that corresponding SPS transmits, if UE receives this PDCCH, then determining that the configuration indicated according to this PDCCH is transmitted by this descending SPS transmission.
In the process realizing the embodiment of the present invention, applicant finds that prior art at least exists following problem:
Consider that in lte-a system, PUCCH can only at up main member carrier (UL PCC, UplinkPrimary Component Carrier) send, and UL PCC is only for descending main member carrier (DL PCC, Downlink Primary Component Carrier) carry out resource reservation, so UE can only obtain implicit information channel resource reserved on UL PCC by the PDCCH of transmission on DLPCC; In addition, if downlink main carrier to carry exists SPS transmission, UE can not obtain implicit information channel resource, the semi-static channel resource that SPS data are corresponding need be used, therefore, the channel resource needed for PUCCH format 1b with channel selection not necessarily can obtain from implicit information channel resource.
In addition, UE may obtain multiple implicit information channel resource according to the PDCCH of multiple descending carriers of the scheduling configuration of transmission on the inherent DL PCC of a descending sub frame, then UE also needs to determine which channel resource the channel resource corresponding to this descending sub frame is specially further, when not having PDCCH to transmit on downlink main carrier to carry, channel resource corresponding to this descending sub frame also can be the semi-static channel resource indicated by resource instructions field (ARI) of RRC (Radio Resource Control, radio resource control) configuration or PDCCH.
At present, in existing technology, corresponding solution is not also had.

Embodiment
As stated in the Background Art, at LTE-A carrier aggregation (CA, carrier aggregation) in system, multiple descending carrier has been polymerized when sending data to user in base station, and UE will feed back the ACK/NACK feedback information of corresponding multiple descending carrier and descending sub frame in a sub-frame of uplink.Determine a kind of scheme that PUCCHFormat 1b with channel selection transmits as ACK/NACK multiplexing (Multiplexing) at present.
When UE needs the ACK/NACK feedback information bits number of feedback to be greater than 4 bit at a sub-frame of uplink, need to merge (bundling) ACK/NACK feedback information, the ACK/NACK feedback information number after merging is made to be less than or equal to 4 bits, to adopt PUCCH Format 1b with channel selection scheme transmission.
But at present, how to determine the scheme that the channel resource corresponding to ACK/NACK feedback information after merging also is not determined.
Based on above reason, the embodiment of the present invention give a kind of adopt the scene of PUCCH format 1b withchannel selection scheme under, determine the method for the channel resource of ACK/NACK feedback information.
In LTE-A TDD system, when UE adopts PUCCH Format 1b with channel selection to feed back M-bit ACK/NACK information, 2≤M≤4, M is positive integer, represents that UE carries out the descending sub frame quantity of ACK/NACK feedback at same sub-frame of uplink, if UE needs the bit number of the ACK/NACK feedback information fed back more than 4 bits in a sub-frame of uplink, then UE needs the ACK/NACK feedback information carried out between descending carrier to merge, for the descending carrier of many codeword transmission pattern, the space of carrying out between many code words is also needed to merge, obtain the ACK/NACK feedback information that M-bit merges, and determine the channel resource corresponding to every bit ACK/NACK feedback information of each descending sub frame or merging, then the ACK/NACK feedback information be combined based on ACK/NACK mapping form selects corresponding channel resource and modulation symbol, and corresponding modulation symbol is sent on the channel resource selected.
As shown in Figure 4, be the schematic flow sheet of the channel resource defining method of a kind of ACK/NACK feedback information of embodiment of the present invention proposition, the method specifically comprises the following steps:
Step S401, terminal equipment M descending sub frame in the descending carrier of C configuration receives data.
Wherein, C >=1, M >=1, the ACK/NACK information of the data in M descending sub frame is transmitted in same sub-frame of uplink.
Step S402, terminal equipment determine a channel resource to each descending sub frame receiving downlink data in M descending sub frame, are determined to many M channel resource.
In actual applications, the channel resource deterministic process of this step, according to the content difference of the definition base of channel resource, can be divided into following two class resource determining method:
If in the descending sub frame of terminal equipment in M descending sub frame, downlink main carrier to carry does not have semi-continuous PDSCH transmission, or on downlink main carrier to carry, there is the PDCCH of the semi-continuous PDSCH of scheduling, then terminal equipment adopts first kind resource determining method determination channel resource;
If in the descending sub frame of terminal equipment in M descending sub frame, downlink main carrier to carry exists semi-continuous PDSCH transmission and in descending sub frame, there is not the PDCCH dispatching semi-continuous PDSCH, then terminal equipment adopts Equations of The Second Kind resource determining method determination channel resource.
Wherein, comprise method one and method two two kinds of situations further in first kind resource determining method, be described as follows;
Method one, the definition base being channel resource with PDCCH received on downlink main carrier to carry or descending auxiliary carrier wave.
Accordingly, this method is divided into two kinds of situations in actual applications:
If in the descending sub frame of situation one terminal equipment in M descending sub frame, downlink main carrier to carry receives at least one PDCCH, and PDCCH is PDCCH or the descending scheduling instruction of dynamic PDSCH on the descending auxiliary carrier wave transmitting downlink main carrier to carry and/or at least one configuration of the semi-continuous PDSCH of scheduling, then terminal equipment determines a channel resource, as the channel resource corresponding to descending sub frame by the minimum CCE numbering of a PDCCH.
In such cases, select the rule of a PDCCH specific as follows at least one PDCCH:
(1) if at least one PDCCH that terminal equipment receives on downlink main carrier to carry comprises the PDCCH of the PDCCH dispatching semi-continuous PDSCH or the descending scheduling instruction transmitting dynamic PDSCH on downlink main carrier to carry, the then PDCCH of the descending scheduling instruction of dynamic PDSCH on the PDCCH of the PDSCH that terminal equipment selection scheduling is semi-continuous or transmission downlink main carrier to carry, and determine channel resource by the minimum CCE numbering of the PDCCH selected;
If the PDCCH of the PDCCH not comprising the semi-continuous PDSCH of scheduling at least one PDCCH that terminal equipment receives on downlink main carrier to carry and the descending scheduling instruction transmitting dynamic PDSCH on downlink main carrier to carry, the precedence information of the descending carrier that the information in the carrier wave instructions field then in the terminal equipment carrier index of descending carrier of dispatching according at least one PDCCH or at least one PDCCH or at least one PDCCH dispatch, in at least one PDCCH, select a PDCCH, and determine channel resource by the minimum CCE numbering of the PDCCH selected.
(2) precedence information of the descending carrier that the information in the carrier wave instructions field in the terminal equipment carrier index of descending carrier of dispatching according at least one PDCCH or at least one PDCCH or at least one PDCCH dispatch, a PDCCH is selected at least one PDCCH, and determine channel resource by the minimum CCE numbering of the PDCCH selected, do not need to distinguish the PDCCH whether PDCCH is dispatching downlink main carrier.
In conjunction with concrete application scenarios, the precedence information of the descending carrier that the information in the carrier wave instructions field in the carrier index of the descending carrier dispatched according at least one PDCCH in above-mentioned (1) and (2) or at least one PDCCH or at least one PDCCH dispatch, at least one PDCCH, select the process of a PDCCH specifically can be refined as following three kinds of rules:
Rule 1, carrier index based on UE configurating downlink carrier wave, as selected in current downlink subframe, the PDCCH of transfer of data on the descending carrier that the scheduling that downlink main carrier to carry transmits has a minimum or maximum downstream carrier index, for determining dynamic channel resource.
Rule 2, based on the carrier wave instructions field (CIF) in PDCCH, as when supporting across carrier dispatching, select in current downlink subframe, the determined dynamic channel resource of the PDCCH with minimum or maximum CIF that downlink main carrier to carry transmits; When not supporting across carrier dispatching, select in current downlink subframe, the PDCCH of transfer of data on the dispatching downlink main carrier that downlink main carrier to carry transmits, for determining dynamic channel resource.
Rule 3, priority based on the descending carrier of predefined configuration, as selected in current downlink subframe, the PDCCH of transfer of data on the descending carrier that the scheduling that downlink main carrier to carry transmits has the highest carrier wave priority, for determining dynamic channel resource.
And further, the proposition rule 4 that can optimize, namely the scheme set forth in aforesaid (1), if in UE current downlink subframe, data are received at downlink main carrier to carry, the PDCCH of data on the dispatching downlink main carrier of then answering prioritizing selection to transmit on downlink main carrier to carry, for determining dynamic channel resource; If UE does not receive data on downlink main carrier to carry, then according to above 3 kinds of selective rules, at least one PDCCH of the descending auxiliary carrier wave of the scheduling that downlink main carrier to carry transmits configuration, one can be selected, for determining dynamic channel resource.
In actual applications, can determine to apply which kind of above-mentioned rule, the content change of concrete institute application rule can't affect protection scope of the present invention according to actual needs.
If in the descending sub frame of situation two terminal equipment in M descending sub frame, downlink main carrier to carry does not receive PDCCH, but on the descending auxiliary carrier wave of at least one configuration, receive PDCCH, and the instruction of the descending scheduling of the PDSCH of PDCCH on the descending auxiliary carrier wave of transmission configuration, then terminal equipment determines a channel resource, as the channel resource corresponding to descending sub frame by the ACK/NACK resource indication bit in PDCCH.
One at least one channel resource that ACK/NACK resource indication bit instruction high-level signaling in PDCCH is pre-configured;
Wherein, if terminal equipment receives at least two PDCCH on the descending auxiliary carrier wave of at least two configurations, the ACK/NACK resource indication bit at least two PDCCH indicates same channel resource
Method two, with the definition base being channel resource for the PDCCH of the descending scheduling instruction transmitting the PDSCH on downlink main carrier to carry received on downlink main carrier to carry or descending auxiliary carrier wave.
Accordingly, this method is divided into two kinds of situations in actual applications:
If in the descending sub frame of situation one terminal equipment in M descending sub frame, downlink main carrier to carry receives PDCCH for dispatching semi-continuous PDSCH or the PDCCH for the descending scheduling instruction of transmitting dynamic PDSCH on downlink main carrier to carry, then terminal equipment is by the PDCCH for dispatching semi-continuous PDSCH or number for the minimum CCE of the PDCCH of the descending scheduling instruction of transmitting dynamic PDSCH on downlink main carrier to carry and determine a channel resource, as the channel resource corresponding to descending sub frame.
Situation two, if in the descending sub frame of terminal equipment in M descending sub frame, downlink main carrier to carry does not receive PDCCH for dispatching semi-continuous PDSCH and the PDCCH for the descending scheduling instruction of transmitting dynamic PDSCH on downlink main carrier to carry, but receive the PDCCH of the descending scheduling instruction for transmitting the PDSCH on descending auxiliary carrier wave on downlink main carrier to carry and/or on the descending auxiliary carrier wave of at least one configuration, then terminal equipment determines a channel resource by the ACK/NACK resource indication bit in the PDCCH of the descending scheduling instruction for transmitting the PDSCH on descending auxiliary carrier wave, as the channel resource corresponding to descending sub frame.
Wherein, one at least one channel resource that the ACK/NACK resource indication bit instruction high-level signaling in PDCCH is pre-configured;
If terminal equipment receives at least two PDCCH of the descending scheduling instruction for transmitting the PDSCH on descending auxiliary carrier wave on the descending auxiliary carrier wave of downlink main carrier to carry and/or configuration, the ACK/NACK resource indication bit at least two PDCCH indicates same channel resource.
It is further noted that, no matter apply which kind of method above-mentioned, be simplified to make the processing procedure in terminal equipment, when there is PDSCH loss in the descending sub frame that terminal equipment judges in M descending sub frame, terminal equipment all can be abandoned as this descending sub frame determination channel resource, thus economize the process of slightly this descending sub frame determination channel resource, save corresponding process resource.
On the other hand, for above-mentioned Equations of The Second Kind resource determining method, be described as follows:
If in the descending sub frame of terminal equipment in M descending sub frame, downlink main carrier to carry receives the PDCCH of the descending scheduling instruction for transmitting dynamic PDSCH on downlink main carrier to carry, then terminal equipment determines a channel resource, as the channel resource corresponding to descending sub frame by the minimum CCE numbering of the PDCCH of the descending scheduling instruction for transmitting dynamic PDSCH on downlink main carrier to carry;
If in the descending sub frame of terminal equipment in M descending sub frame, downlink main carrier to carry does not receive the PDCCH of the descending scheduling instruction for transmitting dynamic PDSCH on downlink main carrier to carry, then semi-continuous in the terminal equipment determination descending sub frame channel resource corresponding to PDSCH is as the channel resource corresponding to descending sub frame, and the channel resource corresponding to semi-continuous PDSCH is for activating in the pre-configured multiple channel resources of high level indicated by the TPC in the PDCCH of semi-continuous PDSCH.
It is pointed out that in above-mentioned declarative procedure, dispatch the PDCCH of semi-continuous PDSCH, specifically comprising the PDCCH for activating semi-continuous PDSCH, or for discharging the PDCCH of semi-continuous PDSCH, PDCCH adopts SPS-RNTI scrambling; The PDCCH transmitting the descending scheduling instruction of dynamic PDSCH adopts C-RNTI or Temporary C-RNTI scrambling.
Step S403, terminal equipment are that each descending sub frame in M descending sub frame generates an ACK/NACK feedback information, produce M-bit feedback bits.
In this step, UE produces the ACK/NACK feedback information of the merging in feedback window corresponding to each descending sub frame, and obtain the ACK/NACK feedback information that M-bit merges, wherein M represents that UE carries out the descending sub frame quantity of ACK/NACK feedback at same sub-frame of uplink;
In actual applications, concrete merging method is the merging that the ACK/NACK feedback information descending carrier to each configuration in a descending sub frame receiving packet carries out between descending carrier, makes the descending carrier of all configurations of UE only ACK/NACK feedback information of merging of corresponding 1 bit in a descending sub frame.
Wherein, be the configurating downlink carrier wave of many code words to transmission mode, UE needs first to merge the ACK/NACK feedback information of the multiple code words received in descending sub frame same on this descending carrier, and namely space merges.
It should be noted that, concrete merging rule is as follows:
When all not receiving downlink data packet or judge downlink data packet loss at least one descending carrier configured on the descending carrier of all configurations of UE in current downlink subframe, DTX is produced as the ACK/NACK feedback information merged to this descending sub frame;
When UE judges to there is not data-bag lost in current downlink subframe, and the feedback information of packet that descending carrier of at least one configuration in this descending sub frame receives is when being NACK (namely receives data packets is incorrect), the ACK/NACK feedback information of NACK as merging is produced to this descending sub frame;
When UE judges to there is not data-bag lost in current downlink subframe, and the feedback information of all packets that the descending carrier of configuration in this descending sub frame receives is when being all ACK (namely packet correctly receives), ACK is produced as the ACK/NACK feedback information merged to this descending sub frame;
Wherein, current downlink subframe is that UE needs to carry out in the descending sub frame of ACK/NACK feedback in a sub-frame of uplink.
Step S404, terminal equipment, according to the M-bit feedback bits generated, select a channel resource in the channel resource of M at the most determined, and determine a corresponding qam constellation point, by the channel resource selected, and the qam constellation point that transmission is determined.
In actual applications, namely the implementation procedure of this step adopts PUCCH format 1b with channelselection scheme to carry out the selection of channel resource.
Then, according to ACK/NACK mapping form, the ACK/NACK feedback information be combined selects corresponding channel resource and modulation symbol (4 QPSK constellation point of PUCCH format 1b), and sends corresponding modulation symbol on the channel resource selected;
Wherein, ACK/NACK mapping form is used for representing the corresponding relation of the modulation symbol (i.e. PUCCH format 1b QPSK modulate 4 constellation point) of the channel resource of ACK/NACK feedback information and actual transmissions and transmission;
Further, the ACK in ACK/NACK mapping form represents and correctly receives packet, and NACK represents erroneous received data bag, and DTX represents data-bag lost or without data packet dispatching.
Corresponding, in base station side, the above-mentioned identical rule of base station applies carries out the determination of channel resource, and select corresponding channel resource to carry out the reception of ACK/NACK feedback information, it is to be noted, because base station side can not determine the situation of the data-bag lost that UE holds, so, determine to occur difference at channel resource in such cases with the processing procedure of aforesaid terminal equipment side, but, because terminal equipment side can not select the channel resource corresponding to the descending sub frame of data-bag lost (corresponding ACK/NACK feedback information is DTX) to carry out the transmission of ACK/NACK feedback information, so, even if terminal equipment and base station there are differences for the determined channel resource of descending sub frame of data-bag lost, also ACK/NACK feedback information is there will not be to receive the situation of mistake.
At this, for the processing procedure no longer repeat specification of base station side.
Compared with prior art, the embodiment of the present invention has the following advantages:

In descending sub frame 2, it downlink main carrier to carry is non-SPS subframe, namely without SPS business, the configurating downlink carrier number of the current downlink subframe scheduling that UE is indicated by frequency domain DAI, downlink main carrier to carry packet loss (feedback states that the downlink data packet of this position is corresponding is DTX) can be judged, and then 1 bit DTX is produced as feedback information to descending sub frame 2; Because UE does not receive data at downlink main carrier to carry, only have received data at descending auxiliary carrier wave (descending carrier 2), and the PDCCH dispatching this descending carrier is in descending 2 carrier transmission, 1 semi-static channel resource in the PDCCH that the channel resource corresponding to descending sub frame 2 is dispatching downlink carrier wave 2 indicated by ARI is determined according to the method one or 2, UE of first kind resource determining method;
In descending sub frame 3, downlink main carrier to carry is non-SPS subframe, namely without SPS business, UE have received data on 2 descending carriers, produces 1 bit NACK as feedback information; Because UE receives data at downlink main carrier to carry, according to rule 4 or the method two of the method one of first kind resource determining method, the channel resource that UE determines corresponding to descending sub frame 3 is that the minimum CCE of the PDCCH of dispatching downlink main carrier numbers 1 the dynamic channel resource determined;
By above-mentioned processing procedure, UE finally generates the ACK/NACK feedback information [ACK that 3 bits merge, DTX, NACK], adopt PUCCH format 1b with channel selection transmission plan, according to ACK/NACK mapping form, determine the transmission channel resources corresponding to ACK/NACK feedback information after merging and modulation symbol, and on selected channel resource, send corresponding modulation symbol.
Base station end:
Base station, according to the transmission mode of the configuration of 2 descending carriers and each descending carrier, is determined that UE needs feedback 6 bit ACK/NACK, is greater than 4 bits, therefore determine that UE merges ACK/NACK feedback information;
Base station, according to actual schedule, adopts the method consistent with UE to determine the channel resource for Channel assignment needing to detect; For the descending sub frame that there is not packet loss, the determined channel resource in base station is consistent with UE; For the descending sub frame that there is packet loss, as descending sub frame 2, base station scheduled packet on downlink main carrier to carry, therefore base station thinks that the channel resource corresponding to ACK/NACK feedback information of merging of this descending sub frame is that the minimum CCE of the PDCCH of dispatching downlink main carrier numbers determined 1 dynamic channel resource, and the channel resource determined with UE is inconsistent; But because this descending sub frame exists packet loss, the feedback information of corresponding merging is DTX, according to ACK/NACK mapping form, UE can not select the channel resource corresponding to DTX state to transmit, therefore, when base station correctly receives, that detects that the ACK/NACK feedback information of merging that obtains and UE send is consistent.
