Abstract

An embodiment of the invention discloses a channel resource determination method of ACK/NACK feedback information and equipment. Through applying a technical scheme of the embodiment, alternative channel resource can be determined in an application scene employing a PUCCH format 1b with channel selection scheme. A determination problem of channel resource needed by channel selection is solved when a terminal device employs the PUCCH format 1b with channel selection scheme to transmit ACK/NACK feedback information which is subjected to configuration downlink intercarrier merging. A situation that the alternative channel resource can not be determined according to present implicit channel resource which is determined by a PDCCH which is transmitted only through a downlink main carrier is avoided. To a scene that the ACK/NACK feedback information is larger than 4 bits, transmission of the ACK/NACK feedback information through the PUCCH format 1b with channel selection scheme is realized. The method and the equipment are mainly suitable for a TDD system.

Description

The channel resource of ACK/NACK feedback information is confirmed method and apparatus

Technical field

The present invention relates to communication technical field, particularly a kind of channel resource of ACK/NACK feedback information is confirmed method and apparatus.

Background technology

For long-term evolution multi-carrier system, for supporting that such as 100MHz, a kind of possibly be the frequency spectrum that directly distributes the 100M bandwidth, as shown in Figure 1 than LTE (Long Term Evolution, Long Term Evolution) the wideer system bandwidth of system; A kind of possibly be with distributing to some spectrum aggregatings of existing systems; Gather into big bandwidth and supply with the long-term evolution multi-carrier system use; The up-downgoing carrier wave can asymmetricly dispose in the system at this moment; Be that the user may take N >=1 carrier wave and carries out downlink transfer, M >=1 carrier wave carries out uplink, and is as shown in Figure 2.

LTE-A (Long Term Evolution Advanced; Senior Long Term Evolution) system confirms to support 5 carrier waves to carry out polymerization at most at present; A LTE-A UE (User Equipment; Subscriber equipment) need be at ACK (Acknowledgement, positive acknowledgement)/NACK (Negative Acknowledgement, the NACK) feedback information of corresponding a plurality of descending carriers of same sub-frame of uplink internal feedback and descending sub frame.Confirm in the LTE-A system at present; The ACK/NACK information bit of UE feedback is confirmed based on the descending carrier of configuration and the transmission mode of each descending carrier; Promptly in FDD (Frequency Division Duplex, FDD) system, UE needs feedback at a sub-frame of uplink

Bit ACK/NACK, wherein C _iBe the code word number (C=1 during the single codeword transmission, C=2 during many codeword transmission) of each descending carrier, the transmission mode of different descending carriers (being the code word number) can be different, and N is a 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 need carry out the ACK/NACK feedback at same sub-frame of uplink, 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 the table 1.Corresponding same sub-frame of uplink carries out a plurality of descending sub frames of ACK/NACK feedback, abbreviates " feedback window " hereinafter as.

Table 1Downlink association set index K:{k ₀, k ₁... K _M-1For TDD

In the LTE-A system; Confirmed 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; This scheme is carried out channel through UE at a plurality of channel resources and is selected transmission to distinguish different ACK/NACK feedback information states; Wherein, ACK/NACK mapping form is exactly the mapping that is used for realizing ACK/NACK information to be feedback and actual channel transmission information (being 4 constellation point of PUCCH format 1b QPSK modulation) 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 is supported 4 bit ACK/NACK feedback at most; When UE needs the ACK/NACK bit number of feedback to surpass 4 in a sub-frame of uplink, need carry out ACK/NACK information and merge (bundling) to reduce the bit number of ACK/NACK feedback information.Merge (claiming frequency domain combination again) between the descending carrier that UE can be configured the ACK/NACK feedback information; Promptly as shown in Figure 3; Sketch map for the ACK/NACK of TDD system feedback information frequency domain combination; The ACK/NACK information of the packet that receives on the descending carrier of UE to each configuration in the current descending sub frame in the feedback window merges, and generates the ACK/NACK feedback information that 1 bit merges, if the descending carrier of configuration is many codeword transmission pattern; Also need the ACK/NACK feedback information of a plurality of code words of receiving on this descending carrier be merged (claiming that again the space merges spatial bundling).The feedback information state comprises ACK (the correct packet that receives), NACK (packet that mistake receives) and DTX (packet of losing or not dispatching).For judging packet loss; 2 bit DAI (Downlink Assignment Index in the LTETDD system among the DL grant; Descending allocation index) sum of the PDCCH that PDCCH with corresponding PDSCH that transmits on the descending carrier that can be used to represent to dispose in the same descending sub frame in the feedback window and indication semi-continuous scheduling (SPS, Semi-Persistent Scheduling) PDSCH discharge.

In the merging process; If UE can judge in the current descending sub frame in the feedback window; Downlink data packet loss on the descending carrier of configuration, depositing (can judge through DAI by losing of the PDSCH of PDCCH that the indication semi-continuous scheduling discharges and PDCCH scheduling; Losing of SPS packet can be judged through the SPS service period), or UE descending carrier in all configurations in current descending sub frame all do not receive downlink data packet, then this descending sub frame generated DTX as the feedback information that merges; If UE judges in the current descending sub frame in the feedback window; On the descending carrier of configuration, there is not the downlink data packet loss; And the feedback information of at least one packet that receives on the descending carrier of a plurality of configurations in this descending sub frame is NACK, then this descending sub frame is generated NACK as the feedback information that merges; If UE judges in the current descending sub frame in the feedback window; On the descending carrier of configuration, there is not the downlink data packet loss; And the feedback information of all packets that receive on the descending carrier that disposes in this descending sub frame all is ACK, then this descending sub frame is generated ACK as the feedback information that merges.

Be configured when being operated in a plurality of descending carrier as UE like this; ACK/NACK number of bits of feedback after can guaranteeing to merge is M; M≤4; Wherein M is the descending sub frame quantity that UE need carry out the ACK/NACK feedback at same sub-frame of uplink, is confirmed with different sub-frame of uplink positions by the uplink-downlink configuration of TDD system.

In the LTE-A system, the reservation of implicit information channel resource is all only reserved to the PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) on the descending carrier of pairing with it on each up-link carrier.So-called implicit information channel resource; It is exactly the uplink control channel resource of the control information zone reservation of a corresponding fixing descending carrier on the up-link carrier; Control information zone wherein is CCE (Control Channel Element, control channel unit), and UE is through the minimum CCE numbering of the descending control signaling (PDCCH) that on this descending carrier, sends; All can calculate and obtain an available uplink control channel resource, abbreviate " implicit information channel resource " or " dynamic channel resource " as.In addition, downlink data transmission also possibly be the business that does not have corresponding PDCCH, i.e. SPS packet.Descending SPS transmission only occurs on the downlink main carrier to carry, by the PDCCH triggering that indication SPS transmission activates, can transmit according to fixing cycle and resource distribution after the triggering, and behind the PDCCH that receives indication SPS transmission release, this SPS end of transmission.Therefore; There is not corresponding PDCCH in the transmission course after SPS is triggered; Therefore do not have the implicit information channel resource, each pairing channel resource of SPS data packet transmission is all identical, is the indicated semi-static channel resource of TPC territory among the PDCCH of indication SPS transmission activation.If the base station need change the SPS transmission configuration, as changing transmission bandwidth etc., then can send a dynamic PDCCH of corresponding SPS transmission, if UE receives this PDCCH, then definite this descending SPS transmission will be transmitted according to the configuration of this PDCCH indication.

In the process that realizes the embodiment of the invention, the applicant finds that there is following problem at least in prior art:

Consider that PUCCH can only be at up main member carrier (UL PCC in the LTE-A system; UplinkPrimary Component Carrier) sends; And UL PCC is only to descending main member carrier (DL PCC; Downlink Primary Component Carrier) carries out resource reservation, so UE can only go up the implicit information channel resource of reserving on the PDCCH acquisition UL PCC of transmission through DLPCC; In addition; If there is the SPS transmission on the downlink main carrier to carry; UE can not obtain the implicit information channel resource; Need to use the semi-static channel resource of SPS data correspondence, therefore, the required channel resource of PUCCH format 1b with channel selection not necessarily can obtain from the implicit information channel resource.

In addition; UE possibly obtain a plurality of implicit information channel resources according to the PDCCH of a plurality of descending carriers of the scheduling configuration of transmission on the inherent DL PCC of a descending sub frame; Then UE needs also further to confirm which channel resource the pairing channel resource of this descending sub frame is specially; When on downlink main carrier to carry, not having the PDCCH transmission; The pairing channel resource of this descending sub frame also can be the indicated semi-static channel resource in resource indication territory (ARI) of RRC (Radio Resource Control, radio resource control) configuration or PDCCH.

At present, in existing technology, also there is not corresponding solution.

Embodiment

Of background technology; At LTE-A carrier aggregation (CA; Carrier aggregation) in the system, the base station polymerization a plurality of descending carriers when the user sends data, UE will feed back the ACK/NACK feedback information of corresponding a plurality of descending carriers and descending sub frame in a sub-frame of uplink.Confirmed a kind of scheme of PUCCHFormat 1b with channel selection at present as ACK/NACK multiplexing (Multiplexing) transmission.

The ACK/NACK feedback information bits number that need feed back at a sub-frame of uplink as UE is during greater than 4 bits; Need merge the ACK/NACK feedback information (bundling); Make ACK/NACK feedback information number after the merging smaller or equal to 4 bits, to adopt the transmission of PUCCH Format 1b with channel selection scheme.

But at present, the pairing channel resource of ACK/NACK feedback information after how confirming to merge does not also have definite scheme.

Based on above reason, the embodiment of the invention has provided under a kind of scene of the PUCCH of employing format 1b withchannel selection scheme, confirms 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 feedback M bit ACK/nack message, 2≤M≤4, M is a positive integer, expression 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 of feedback to surpass 4 bits in a sub-frame of uplink; Then UE need carry out the ACK/NACK feedback information merging between descending carrier; Descending carrier for many codeword transmission pattern; The space that also need carry out between many code words merges, and obtains the ACK/NACK feedback information that the M bit merges, and confirms the every bit ACK/pairing channel resource of NACK feedback information of each descending sub frame or merging; The ACK/NACK feedback information that is combined based on ACK/NACK mapping form is then selected corresponding channel resource and modulation symbol, and on the channel resource of selecting, sends corresponding modulation symbol.

As shown in Figure 4, the channel resource of a kind of ACK/NACK feedback information that proposes for the embodiment of the invention is confirmed the schematic flow sheet of method, and this method specifically may further comprise the 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 confirm a channel resource to the descending sub frame that in M the descending sub frame each receives downlink data, are determined to many M channel resource.

In practical application, the channel resource deterministic process of this step can be divided into following two types of resource determining method according to the content difference of definite foundation of channel resource:

If in the descending sub frame of terminal equipment in M descending sub frame; On downlink main carrier to carry, there is not semi-continuous PDSCH transmission; Or on downlink main carrier to carry, have the PDCCH that dispatches semi-continuous PDSCH, then terminal equipment adopts first kind resource determining method to confirm channel resource;

If in the descending sub frame of terminal equipment in M descending sub frame; Have semi-continuous PDSCH transmission on the downlink main carrier to carry and in descending sub frame, do not having the PDCCH that dispatches semi-continuous PDSCH, then terminal equipment adopts second type of resource determining method to confirm channel resource.

Wherein, in first kind resource determining method, further comprise method one and two kinds of situation of method two, specify as follows;

Method one, be definite foundation of channel resource with received PDCCH on downlink main carrier to carry or the descending auxilliary carrier wave.

Accordingly, this method is divided into two kinds of situation in actual applications:

If in the descending sub frame of situation one terminal equipment in M descending sub frame; On downlink main carrier to carry, receive at least one PDCCH; And PDCCH is for the PDCCH of the semi-continuous PDSCH of scheduling or be used to transmit the descending scheduling indication of dynamic PDSCH on the descending auxilliary carrier wave of downlink main carrier to carry and/or at least one configuration; Then terminal equipment is confirmed a channel resource through the minimum CCE numbering of a PDCCH, as the pairing channel resource of descending sub frame.

In such cases, select at least one PDCCH that a PDCCH's is regular specific as follows:

(1) if the PDCCH of the descending scheduling indication that comprises the PDCCH that dispatches semi-continuous PDSCH among at least one PDCCH that terminal equipment receives or transmit dynamic PDSCH on the downlink main carrier to carry on downlink main carrier to carry; The PDCCH of the descending scheduling indication of dynamic PDSCH on the PDCCH of the semi-continuous PDSCH of terminal equipment selection scheduling or the transmission downlink main carrier to carry then, and confirm channel resource through the minimum CCE numbering of the PDCCH that selects;

If do not comprise the PDCCH of the PDSCH that scheduling is semi-continuous and the PDCCH of the descending scheduling indication of transmitting dynamic PDSCH on the downlink main carrier to carry among at least one PDCCH that terminal equipment receives on downlink main carrier to carry; Then terminal equipment is according to carrier index or the information in the indication of the carrier wave among at least one PDCCH territory or the precedence information of the descending carrier that at least one PDCCH dispatched of the descending carrier that at least one PDCCH dispatched; In at least one PDCCH, select a PDCCH, and pass through the definite channel resource of minimum CCE numbering of the PDCCH of selection.

(2) terminal equipment is according to carrier index or the information in the indication of the carrier wave among at least one PDCCH territory or the precedence information of the descending carrier that at least one PDCCH dispatched of the descending carrier that at least one PDCCH dispatched; In at least one PDCCH, select a PDCCH; And confirm channel resource through the minimum CCE numbering of the PDCCH that selects, whether need not distinguish PDCCH is the PDCCH of dispatching downlink main carrier.

In conjunction with concrete application scenarios; According to carrier index or the information in the indication of the carrier wave among at least one PDCCH territory or the precedence information of the descending carrier that at least one PDCCH dispatched of the descending carrier that at least one PDCCH dispatched, at least one PDCCH, select the processing of a PDCCH can specifically be refined as following three kinds of rules in above-mentioned (1) and (2):

Rule 1, based on the carrier index of UE configurating downlink carrier wave, as select in the current descending sub frame, the scheduling of transmitting on the downlink main carrier to carry has the PDCCH of transfer of data on the descending carrier of minimum or maximum downstream carrier index, is used for confirming the dynamic channel resource.

Rule 2, based on the carrier wave among PDCCH indication territory (CIF), as when supporting to stride carrier dispatching, select in the current descending sub frame the determined dynamic channel resource of the PDCCH that transmits on the downlink main carrier to carry with minimum or maximum CIF; When not supporting to stride carrier dispatching, select in the current descending sub frame, the PDCCH of transfer of data on the dispatching downlink main carrier that transmits on the downlink main carrier to carry is used for confirming the dynamic channel resource.

Rule 3, based on the priority of the descending carrier of predefined configuration, as select in the current descending sub frame, the scheduling of transmitting on the downlink main carrier to carry has the PDCCH of transfer of data on the descending carrier of the highest carrier wave priority, is used for confirming the dynamic channel resource.

And further; The proposition rule 4 that can optimize; The scheme of being set forth in promptly aforesaid (1) is if in the current descending sub frame of UE, receive data at downlink main carrier to carry; Then should preferentially be chosen in the PDCCH of data on the dispatching downlink main carrier that transmits on the downlink main carrier to carry, be used for confirming the dynamic channel resource; If UE does not receive data on downlink main carrier to carry, then can be based on above 3 kinds of selective rules, select one among at least one PDCCH of the descending auxilliary carrier wave of the scheduling of on downlink main carrier to carry, transmitting configuration, be used for confirming the dynamic channel resource.

In actual applications, can confirm to use which kind of above-mentioned rule according to actual needs, the content change of concrete institute application rule can't influence protection scope of the present invention.

If in the descending sub frame of situation two terminal equipments in M descending sub frame; On downlink main carrier to carry, do not receive PDCCH; But on the descending auxilliary carrier wave of at least one configuration, receive PDCCH; And PDCCH is used for the descending scheduling indication of the PDSCH on the descending auxilliary carrier wave of transmission configuration, and then terminal equipment is confirmed a channel resource through the ACK/NACK resource indication bit among the PDCCH, as the pairing channel resource of descending sub frame.

ACK/NACK resource indication bit among the PDCCH is indicated at least one pre-configured channel resource of high-level signaling;

Wherein, if terminal equipment receives at least two PDCCH on the descending auxilliary carrier wave of at least two configurations, the ACK/NACK resource indication bit among at least two PDCCH is indicated same channel resource

Method two, the PDCCH that transmits the descending scheduling indication of the PDSCH on the downlink main carrier to carry with received being used on downlink main carrier to carry or the descending auxilliary carrier wave are definite foundation of channel resource.

If in the descending sub frame of situation one terminal equipment in M descending sub frame; Receiving the PDCCH that is used to dispatch the PDCCH of semi-continuous PDSCH or is used to transmit the descending scheduling indication of dynamic PDSCH on the downlink main carrier to carry on the downlink main carrier to carry; Then terminal equipment is confirmed a channel resource through the minimum CCE numbering of PDCCH that is used to dispatch the PDCCH of semi-continuous PDSCH or is used to transmit on the downlink main carrier to carry descending scheduling indication of dynamic PDSCH, as the pairing channel resource of descending sub frame.

If in the descending sub frame of situation two terminal equipments in M descending sub frame; Do not receiving the PDCCH and the PDCCH that is used to transmit the descending scheduling of PDSCH indication dynamically on the downlink main carrier to carry that is used to dispatch semi-continuous PDSCH on the downlink main carrier to carry; But at the PDCCH that receives the descending scheduling indication that is used to transmit the PDSCH on the descending auxilliary carrier wave on the downlink main carrier to carry and/or on the descending auxilliary carrier wave of at least one configuration; Then the ACK/NACK resource indication bit of the PDCCH of the descending scheduling indication of terminal equipment through being used for transmitting the PDSCH on the descending auxilliary carrier wave is confirmed a channel resource, as the pairing channel resource of descending sub frame.

Wherein, the ACK/NACK resource indication bit among the PDCCH is indicated at least one pre-configured channel resource of high-level signaling;

If terminal equipment is at least two PDCCH that receive the descending scheduling indication that is used to transmit the PDSCH on the descending auxilliary carrier wave on the descending auxilliary carrier wave of downlink main carrier to carry and/or configuration, the ACK/NACK resource indication bit among at least two PDCCH is indicated same channel resource.

Need further be pointed out that; No matter use above-mentioned which kind of method; In order to make the processing procedure in the terminal equipment obtain simplifying, when a descending sub frame in M descending sub frame of terminal equipment judgement existed PDSCH to lose, terminal equipment all can be abandoned confirming channel resource for this descending sub frame; Thereby economize the process that this descending sub frame is slightly confirmed channel resource, practiced thrift corresponding processing resource.

On the other hand, second type of resource determining method for above-mentioned specifies as follows:

If in the descending sub frame of terminal equipment in M descending sub frame; At the PDCCH that receives the descending scheduling indication that is used to transmit dynamic PDSCH on the downlink main carrier to carry on the downlink main carrier to carry; Then terminal equipment is numbered definite channel resource through the minimum CCE that is used to transmit the PDCCH of the descending scheduling of PDSCH indication dynamically on the downlink main carrier to carry, as the pairing channel resource of descending sub frame;

If in the descending sub frame of terminal equipment in M descending sub frame; At the PDCCH that does not receive the descending scheduling indication that is used to transmit dynamic PDSCH on the downlink main carrier to carry on the downlink main carrier to carry; Then terminal equipment is confirmed the pairing channel resource of PDSCH semi-continuous in the descending sub frame as the pairing channel resource of descending sub frame, and the pairing channel resource of semi-continuous PDSCH is one in the indicated high-rise pre-configured a plurality of channel resources of the TPC among the PDCCH that activates semi-continuous PDSCH.

It is pointed out that in above-mentioned declarative procedure, dispatch the PDCCH of semi-continuous PDSCH, specifically comprise the PDCCH that is used to activate semi-continuous PDSCH, or be used to discharge the PDCCH of semi-continuous PDSCH, PDCCH adopts the SPS-RNTI scrambling; The PDCCH that transmits the descending scheduling indication of dynamic PDSCH adopts C-RNTI or Temporary C-RNTI scrambling.

Step S403, terminal equipment are that each descending sub frame in M the descending sub frame generates an ACK/NACK feedback information, produce M bit feedback bit.

In this step, UE produces the ACK/NACK feedback information of the pairing merging of each descending sub frame in the feedback window, obtains the ACK/NACK feedback information that the M bit merges, and wherein M representes that UE carries out the descending sub frame quantity of ACK/NACK feedback at same sub-frame of uplink;

In practical application; Concrete merging method makes the descending carrier ACK/NACK feedback information that only corresponding 1 bit merges in a descending sub frame of all configurations of UE for the ACK/NACK feedback information that receives packet on the descending carrier to each configuration in the descending sub frame carries out the merging between descending carrier.

Wherein, be the configurating downlink carrier wave of many code words to transmission mode, UE needs at first the ACK/NACK feedback information of a plurality of code words that receive in the same descending sub frame on this descending carrier is merged, and promptly the space merges.

Need to prove that concrete merging is regular as follows:

This descending sub frame is not produced DTX as the ACK/NACK feedback information that merges when all receiving downlink data packet on the descending carrier of all configurations of UE in current descending sub frame or judging when having the downlink data packet loss on the descending carrier of at least one configuration;

When judging, UE do not have data-bag lost in the current descending sub frame; And when the feedback information of the packet of receiving on the descending carrier of at least one configuration in this descending sub frame is NACK (being that the packet reception is incorrect), this descending sub frame is produced NACK as the ACK/NACK feedback information that merges;

When judging, UE do not have data-bag lost in the current descending sub frame; And when the feedback information of all packets that receive on the descending carrier of the configuration in this descending sub frame all is ACK (being that packet correctly receives), this descending sub frame is produced ACK as the ACK/NACK feedback information that merges;

Wherein, current descending sub frame is that UE need carry out in the descending sub frame of ACK/NACK feedback in a sub-frame of uplink.

Step S404, terminal device are selected a channel resource based on the M bit feedback bit that generates in the channel resource of confirming of M at the most, and confirm the qam constellation point of a correspondence, through the channel resource of selecting, send the qam constellation point of confirming.

In practical application, the implementation procedure of this step promptly 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 that is combined is selected corresponding channel resource and modulation symbol (4 QPSK constellation point of PUCCH format 1b), and on the channel resource of selecting, sends corresponding modulation symbol;

Wherein, ACK/NACK mapping form is used for representing the corresponding relation of the channel resource of ACK/NACK feedback information and actual transmissions and the modulation symbol of transmission (being 4 constellation point of PUCCH format 1b QPSK modulation);

Further, the ACK in the ACK/NACK mapping form representes correctly to receive packet, and NACK representes that mistake receives packet, and DTX representes data-bag lost or free of data packet scheduling.

Corresponding, in base station side, the above-mentioned identical rule of base station applies is carried out confirming of channel resource; And select corresponding channel resources to carry out the reception of ACK/NACK feedback information; It is pointed out that because base station side can not be confirmed the situation of the data-bag lost of UE end, so; Confirm difference to occur at channel resource in such cases with the processing procedure of aforesaid terminal equipment side; But, because terminal equipment side can not select the pairing channel resource of 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 terminal equipment and base station there are differences for the determined channel resource of the descending sub frame of data-bag lost, can not occur the ACK/NACK feedback information yet and receive wrong situation.

At this, for the no longer repeat specification of processing procedure of base station side.

Below, the application scenarios in conjunction with concrete describes the technical scheme that the embodiment of the invention proposed.

Embodiment 1

Method one in the first kind resource determining method among the corresponding step S402.

UE has disposed 2 descending carriers, and descending carrier 1 is a downlink main carrier to carry, and descending carrier 1 adopts many codeword transmission pattern; No SPS transmission subframe on the downlink main carrier to carry, descending carrier 2 adopts single codeword transmission mode, M=4; It is UE need feed back 4 descending sub frames at a sub-frame of uplink ACK/NACK feedback information; Do not support to stride carrier dispatching, as shown in Figure 5, then the flow process of transferring ACK/NACK is following:

The UE end:

UE need to confirm feedback 12 bit ACK/NACK according to the transmission mode of 2 descending carrier configurations and each descending carrier, greater than 4 bits, therefore need carry out ACK/NACK and merge.

Because downlink main carrier to carry (descending carrier 1) is many codeword transmission pattern, need its space of carrying out between many code words is merged.

Then, carry out the merging of the ACK/NACK feedback information in each descending sub frame, the processing procedure of merging is following:

In descending sub frame 1, UE has received data on two descending carriers, produces the feedback information of the ACK of 1 bit merging as descending sub frame 1; Owing to have transfer of data on the downlink main carrier to carry; According to the selective rule 4 of the method one of first kind resource determining method, UE confirms that descending sub frame 1 pairing channel resource is 1 dynamic channel resource that the minimum CCE numbering of the PDCCH of dispatching downlink main carrier is confirmed;

In descending sub frame 2; UE is through the configurating downlink carrier number of the current descending sub frame scheduling of frequency domain DAI indication; Can judge downlink main carrier to carry packet loss (the corresponding feedback states of the downlink data packet of this position is DTX), and then descending sub frame 2 is produced 1 bit DTX as feedback information; Because UE has only received data at descending carrier 2; And this packet is dispatched by the PDCCH on the descending carrier 2; Based on the method one of first kind resource determining method, UE confirms that descending sub frame 2 pairing channel resources are 1 indicated semi-static channel resource of ARI among the PDCCH of dispatching downlink carrier wave 2;

In descending sub frame 3, UE can judge that descending carrier 1 does not have scheduling (this position does not have feedback states) through DAI, produces NACK that 1 bit the merges feedback information as descending sub frame 3 based on the ACK/NACK feedback information of the packet that receives on the descending carrier 2; Because UE has only received packet at descending carrier 2; And this packet is dispatched by the PDCCH on the descending carrier 2; According to the method one of first kind resource determining method, UE confirms that descending sub frame 3 pairing channel resources are 1 indicated semi-static channel resource of ARI among the PDCCH of dispatching downlink carrier wave 2;

In descending sub frame 4, UE does not receive any data, produces 1 bit DTX as its feedback information.

Through above-mentioned processing procedure, UE finally generates ACK/NACK feedback information [ACK, the DTX that 4 bits merge; NACK; DTX], adopt PUCCH format 1b with channel selection transmission plan, according to ACK/NACK mapping form; Pairing transmission channel resources of ACK/NACK feedback information and modulation symbol after confirming to merge, and on selected channel resource, send corresponding modulation symbol;

Base station end:

The base station confirms that according to the transmission mode of 2 descending carrier configurations and each descending carrier UE need feed back 12 bit ACK/NACK, greater than 4 bits, therefore, confirms that UE merges the ACK/NACK feedback information;

The base station adopts the method consistent with UE need to confirm the channel resource that channel is selected that is used for of detection according to actual schedule; For the descending sub frame that does not have packet loss, the determined channel resource in base station is consistent with UE; For the descending sub frame that has packet loss; Like descending subframe 2; Packet has been dispatched in the base station on downlink main carrier to carry; Therefore the base station thinks that the pairing channel resource 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 is inconsistent with the determined channel resource of UE; But because there is packet loss in this descending sub frame; The feedback information of pairing merging is DTX; According to ACK/NACK mapping form, UE can not be chosen in the pairing channel resource of DTX state and transmit, therefore; When the base station correctly received, it is consistent that the ACK/NACK feedback information that detects resulting merging and UE send;
