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 of time domain merging 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 downlink inter-subframe merging. A situation that the alternative channel resource can not be determined for the scene according to the prior art is avoided. In a scene that the ACK/NACK feedback information is larger than 4 bits and the time domain merging is applied, 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 determined 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 determined method and apparatus.

Background technology

For long-term evolution multi-carrier system, for supporting than LTE (Long Term Evolution, Long Term Evolution) the wider system bandwidth of system, such as 100MHz, a kind of may be the frequency spectrum that directly distributes 100M bandwidth, as shown in Figure 1; A kind of may be to distribute to some spectrum aggregatings of existing system, gather into large bandwidth and supply with long-term evolution multi-carrier system use, now in system, up-downgoing carrier wave can asymmetricly configure, be that 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 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) 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.In UTE-A system, determine at present, the transmission mode of the descending carrier of the ACK/NACK information bit that UE feeds back based on configuration and each descending carrier is determined, in FDD (Frequency Division Duplex, Frequency Division Duplexing (FDD)) system, UE needs feedback at a sub-frame of uplink bit ACK/NACK, the code word number that wherein Ci is each descending carrier (C=1 during single codeword transmission, C=2 during many codeword transmission), the transmission mode of different descending carriers (being code word number) 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 m bit ACK/NACK, wherein M is that UE need to carry out the descending sub frame quantity of 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 table 1.Corresponding same sub-frame of uplink carries out a plurality of descending sub frames of ACK/NACK feedback, hereinafter referred to as " feedback window ".

Table 1 Downlink association set index K:{k ₀, k ₁... k _m-ifor TDD

In LTE-A system, determine and can adopt PUCCH (Physical Uplink Control Channel for being no more than 4 bit ACK/nack message, Physical Uplink Control Channel) format 1b with channel selection transmission plan, this scheme is carried out channel by 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 for realizing the mapping of 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 respectively 2,3,4 PUCCH format 1a/1b uplink control channel resources.

In LTE-A TDD system, because PUCCH Format 1b with channel selection transmission plan is supported at most 4 bit ACK/NACK feedback, when UE needs the ACK/NACK bit number of feedback to surpass 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.UE can merge to the corresponding ACK/NACK feedback information of the packet receiving in a plurality of descending sub frames in feedback window on the descending carrier of a configuration (claiming again time domain to merge), obtains the L bit ACK/NACK feedback information b merging ₀, b ₁... b _l-1,, as shown in Figure 3, wherein, N≤L≤2N, N is the descending carrier number of UE polymerization.If the descending carrier of configuration is many codeword transmission pattern, UE need carry out space merging to the descending carrier of 2N-L configuration, to receiving the ACK/NACK feedback information of a plurality of code words in same descending sub frame on this descending carrier, merge and (claim again space to merge, spatial bundling), can preferentially to descending auxiliary carrier wave, merge.Feedback information state comprises ACK (the correct packet receiving), NACK (packet that mistake receives) and DTX (packet of losing or not dispatching).In merging process, if the descending carrier that UE can judge current configuration in feedback window internal memory downlink data packet loss (PDCCH that indication semi-continuous scheduling discharges and the loss with the PDSCH of dynamic PDCCH scheduling can judge by DAI, the loss of SPS packet can judge by SPS service period), or UE does not receive any packet on the descending carrier of current configuration in feedback window, this descending carrier is generated to DTX as the feedback information merging; If UE judges current configurating downlink carrier wave and do not have downlink data packet loss in feedback window, and the feedback information of at least one packet receiving on this descending carrier is NACK, this descending carrier generated to NACK as the feedback information merging; If UE judges current configurating downlink carrier wave and do not have downlink data packet loss in feedback window, and the feedback information of all packets that receive on this descending carrier is all ACK, this descending carrier generated to ACK as the feedback information merging.

While considering that carrying out time domain merges, because UE cannot know the actual schedule situation (be the descending sub frame/number-of-packet of base station actual schedule) of base station in a plurality of descending sub frames, therefore cannot judge whether the descending sub frame being finally scheduled has data-bag lost, thereby make ACK/NACK information after the merging of UE feedback can not reflect really the reception condition of actual schedule data, cause the misinterpretation of base station to ACK/NACK feedback information, the reliability of impact transmission.In order to solve UE that in merging process, data-bag lost causes and base station, understand differently and cause problem, can adopt the Merge Scenarios as shown in Fig. 4 A and 4B, 1) as shown in Figure 4 A, the DAI in DL grant does as a wholely (to be designated as DAI _total), be used to indicate in feedback window, till the sum of the PDSCH that current descending sub frame is dispatched; 2) DAI reusing in LTE TDD DL grant as shown in Figure 4 B, (is designated as DAI _f), be used to indicate the PDSCH sum on different descending carriers in current sub-downlink frame with dynamic PDCCH.Pass through DAI, whether the data packet transmission in the middle of UE can judge loses, UE by the descending sub frame number with dynamic PDCCH receiving in feedback window (PDCCH that comprises dynamic dispatching PDSCH transmission, and the PDCCH that discharges of indication SPS PDSCH resource) as 1 or 2 bit overhead bits with the ACK/NACK feedback information cascade transmission merging.Like this, base station can be by rear 1～2 bit information in the ACK/NACK feedback information receiving, and whether the packet of the last scheduling of judgement loses that (overhead bit is DAI _tduring information) or judge in feedback window, whether there is data-bag lost (overhead bit is the actual descending sub frame number receiving of UE in feedback window), thus avoid merging the unnecessary re-transmission in transmission, improve system efficiency of transmission.

In realizing the process of the embodiment of the present invention, applicant finds that prior art at least exists following problem:

In LTE-A system, on each up-link carrier, the reserved of implicit information channel resource only reserved for the PDCCH on the descending carrier of pairing with it.So-called implicit information channel resource, it is exactly the reserved uplink control channel resource in control information region (each CCE) of a corresponding fixing descending carrier on a up-link carrier, UE is by minimum CCE (the Control Channel Element) numbering of the descending control signaling (PDCCH) that sends on this descending carrier, all can calculate and obtain an available uplink control channel resource, referred to as " implicit information channel resource " or " dynamic channel resource ".In addition, downlink data transmission may be also the business that there is no corresponding PDCCH, i.e. SPS packet.Descending SPS transmission only occurs on downlink main carrier to carry, transmits the PDCCH activating trigger by an indication SPS, can transmit according to fixing cycle and resource distribution, until receive after the PDCCH of indication SPS transmission release this SPS end of transmission after triggering.Therefore, in transmitting procedure after SPS is triggered, there is no corresponding PDCCH, therefore without implicit information channel resource, each corresponding channel resource of SPS data packet transmission is all identical, is the indicated semi-static channel resource of TPC territory in the PDCCH of indication SPS transmission activation.If base station need to change SPS transmission configuration, as changed transmission bandwidth etc., can send a dynamic PDCCH of corresponding SPS transmission, if UE receives this PDCCH, determine that this descending SPS transmits the configuration that will indicate according to this PDCCH and transmit.Consider that in LTE-A system, PUCCH can only be at up main carrier (UL PCC, uplink primary component carrier) send, and UL PCC is only for downlink main carrier to carry (DL PCC, downlink primary component carrier) carry out resource reservation, so UE can only obtain reserved implicit information channel resource on UL PCC by the PDCCH of transmission on DL PCC, so the required channel resource of PUCCH format 1b with channel selection not necessarily can obtain from implicit information channel resource.In addition, UE may receive the PDCCH transmitting on downlink main carrier to carry in a plurality of descending sub frames on a descending carrier in feedback window, and then obtain a plurality of implicit information channel resources, UE also needs further to determine which channel resource the corresponding channel resource of this descending carrier is specially, while there is not the PDCCH transmitting on downlink main carrier to carry on this descending carrier in feedback window, the corresponding channel resource of this descending carrier can be the indicated semi-static channel resource in resource indication territory (ARI) of RRC configuration or PDCCH.

At present, in existing technology, also there is no corresponding solution.

Embodiment

As stated in the Background Art, at LTE-A carrier aggregation (CA, carrier aggregation) in system, base station polymerization a plurality of descending carriers while sending data to user, UE will feed back the ACK/NACK feedback information of corresponding a plurality of descending carrier and descending sub frame in a sub-frame of uplink.Determined at present a kind of scheme of PUCCH Format 1b with channel selection as ACK/NACK multiplexing (Multiplexing) transmission.

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

But the corresponding channel resource of ACK/NACK feedback information that at present, how to confirm carries out merging after (time domain merging) between different subframes does not also have definite scheme.

Based on above reason, the embodiment of the present invention has provided under a kind of scene of the PUCCH of employing format 1b with channel selection scheme, determines 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, for positive integer, represent 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 of feedback to surpass 4 bits in a sub-frame of uplink, UE need to merge receiving the ACK/NACK feedback information of data in different descending sub frames in feedback window on a descending carrier, and needs to determine the channel resource of channel selection.

As shown in Figure 5, the channel resource of a kind of ACK/NACK feedback information proposing for the embodiment of the present invention is determined the schematic flow sheet of method, and the method specifically comprises the following steps:

Step S501, 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 a described M descending sub frame is transmitted in same sub-frame of uplink.

Step S502, terminal equipment are that the data that receive in M descending sub frame generate the feedback bits of L bit, and generate the supplementary of T bit, and supplementary is used to indicate the number that receives the descending sub frame that has PDCCH in M descending sub frame.

Wherein, L >=C.

In concrete application scenarios, the specific implementation process of this step is: UE receives data at descending carrier and M the descending sub frame of N configuration, produce L+T bit feedback bit, wherein, N≤L≤4-T, N is the descending carrier number of UE configuration, N≤3, and M is that UE carries out the descending sub frame quantity of ACK/NACK feedback at same sub-frame of uplink;

Wherein, first UE obtains the ACK/NACK feedback information that L bit merges; Concrete merging method is for merging receiving the ACK/NACK feedback information of packet of the descending sub frame of data in M descending sub frame on the descending carrier of each configuration.

Then, UE has the descending sub frame of PDCCH in feedback window number according to the descending carrier of all configurations generates T bit supplementary, forms M bit feedback bit with the ACK/NACK feedback information cascade merging, and T can be fixed as 2 bits, or

Step S503, described terminal equipment are determined L+T alternative channel resource.

In concrete application scenarios, this step is divided into following five kinds of modes and carries out determining of alternative channel resource:

Method one, terminal equipment determine that L+T the pre-configured channel resource of high-level signaling receiving is alternative channel resource.

High-rise according to the concrete configuration of UE, as needed the descending sub frame number M of feeding back ACK/nack message, a pre-configured L+T channel resource in a sub-frame of uplink;

During M=2, L=1 or L=2 or L=3, preferably configure latter two value or second value;

During M=3, L=1 or L=2, preferably configure rear 1 value;

During M=4, L=1 or L=2, preferably configure rear 1 value.

Method two, this method comprise following two class resource determining method:

If in M descending sub frame, on downlink main carrier to carry, there is no semi-continuous PDSCH transmission, or there is semi-continuous PDSCH transmission and have corresponding PDCCH in the descending sub frame of semi-continuous PDSCH transmission, PDCCH activates or indicates the PDCCH of the PDCCH that semi-continuous PDSCH resource discharges or the descending scheduling indication of transmitting dynamic PDSCH for the semi-continuous PDSCH of indication, and terminal equipment adopts first kind resource determining method to determine channel resource;

If in M descending sub frame, on downlink main carrier to carry, there is semi-continuous PDSCH transmission and there is no corresponding PDCCH in the descending sub frame of semi-continuous PDSCH transmission, PDCCH activates or indicates the PDCCH of the PDCCH that semi-continuous PDSCH resource discharges or the descending scheduling indication of transmitting dynamic PDSCH for the semi-continuous PDSCH of indication, and terminal equipment adopts Equations of The Second Kind resource determining method to determine channel resource.

First kind resource determining method comprises following 3 kinds of situations:

If situation one is in M descending sub frame, terminal equipment has been received the PDCCH of the descending carrier of corresponding K configuration on downlink main carrier to carry, the PDCCH of the descending scheduling indication that PDCCH is PDSCH on the descending carrier of K configuration of transmission and/or the PDCCH that indicates semi-continuous PDSCH to discharge, terminal equipment is determined to many K channel resource according to the CCE numbering of the PDCCH of first descending sub frame of dispatching on the descending carrier of corresponding K in PDCCH configuration, as the channel resource corresponding to descending carrier of K configuration described in alternative channel resource;

In such cases, if terminal equipment judges the data-bag lost of first descending sub frame of dispatching at least one descending carrier, terminal equipment is determined to many K dynamic channel resources according to the CCE numbering of the PDCCH of the packet receiving at least one descending carrier of scheduling, as alternative channel resource, or abandon determining the channel resource of at least one descending carrier.

Above-mentioned situation can be specially following process:

If in M descending sub frame, UE has received the PDCCH of K descending carrier of scheduling on downlink main carrier to carry, the PDCCH that described PDCCH activates or discharges for indication SPS PDSCH, and/or for dispatching the PDCCH of the dynamic PDSCH on the descending carrier configuring, 1≤K≤L, UE determines the corresponding channel resource of descending carrier of this configuration as follows:

Method A, UE determine first descending sub frame (DAI dispatching on this descending carrier of scheduling _t=0 subframe) K at the most the dynamic channel resource that the CCE numbering of PDCCH is determined, K≤L, if data-bag lost (passing through DAI) in first descending sub frame of UE judgement scheduling, UE can uncertain this descending carrier or the corresponding channel resource of code word or employing method B determine resource;

Method B, UE determine K at the most the dynamic channel resource that the CCE numbering of the PDCCH of first descending sub frame that receives data on this descending carrier of scheduling is determined, K≤L;

Wherein, PDCCH transmits at downlink main carrier to carry, can be used for the transfer of data on the descending auxiliary carrier wave of dispatching downlink main carrier or configuration.

If situation two is in M descending sub frame, terminal equipment receives PDSCH at least one descending auxiliary carrier wave of configuration, and the PDCCH that the descending scheduling that transmits PDSCH at least one descending auxiliary carrier wave is indicated is in descending auxiliary carrier transmission, terminal equipment is determined 1 channel resource of the ACK/NACK resource indication bit indication of the PDCCH that the descending scheduling of PDSCH at least one descending auxiliary carrier wave of transmission is indicated, as the corresponding channel resource of at least one descending auxiliary carrier wave in alternative channel resource.

Under similar application scenarios, the implementation procedure of this kind of situation can be specially:

Dispatch on same descending carrier the ARI in a plurality of PDCCH of transfer of data in a plurality of descending sub frames and need indicate same channel resource;

Situation three, terminal equipment determine that T channel resource of high-rise configuration is the corresponding channel resource of T bit supplementary.

Equations of The Second Kind resource determining method comprises following 4 kinds of situations:

Situation one, terminal equipment determine that the corresponding channel resource of PDSCH semi-continuous on downlink main carrier to carry is as the corresponding channel resource of downlink main carrier to carry in alternative channel resource.

Wherein, the corresponding channel resource of this semi-continuous PDSCH is the indicated pre-configured channel resource of high level of TPC bit in the PDCCH of the semi-continuous PDSCH activation of indication.

Above-mentioned situation can be specially following process:

The corresponding channel resource of downlink main carrier to carry is the corresponding channel resource of SPS PDSCH, and the corresponding channel resource of SPSPDSCH is for activating in the pre-configured channel resource of the indicated high level in TPC territory in the PDCCH of this SPS PDSCH.

If situation two is in a described M descending sub frame, terminal equipment has been received the PDCCH of the descending auxiliary carrier wave of corresponding K configuration on downlink main carrier to carry, the PDCCH of the descending scheduling indication that described PDCCH is PDSCH on the descending auxiliary carrier wave of K configuration of transmission, terminal equipment is determined to many K channel resource according to the CCE numbering of the PDCCH of first descending sub frame of dispatching on the descending auxiliary carrier wave of corresponding K in described PDCCH configuration, as the channel resource corresponding to descending auxiliary carrier wave of K configuration described in alternative channel resource;

Above-mentioned situation can be specially following process:

If in M descending sub frame, UE has received the PDCCH of K descending auxiliary carrier wave of scheduling on downlink main carrier to carry, described PDCCH is the PDCCH of the PDSCH on the descending auxiliary carrier wave of scheduling configuration, 1≤K≤N-1, UE determines the corresponding channel resource of descending carrier of this configuration as follows:

PDCCH transmits at downlink main carrier to carry, for dispatching the transfer of data on the descending auxiliary carrier wave of configuration.

If situation three is in M descending sub frame, terminal equipment receives PDSCH at least one descending auxiliary carrier wave of configuration, and the PDCCH that the descending scheduling that transmits PDSCH at least one descending auxiliary carrier wave is indicated is in descending auxiliary carrier transmission, terminal equipment is determined 1 channel resource of the ACK/NACK resource indication bit indication of the PDCCH that the descending scheduling of PDSCH at least one descending auxiliary carrier wave of transmission is indicated, as the corresponding channel resource of at least one descending auxiliary carrier wave in alternative channel resource.

Wherein, PDCCH transmits on the descending auxiliary carrier wave of configuration, for dispatching the transfer of data on the one or more descending auxiliary carrier wave of configuration of described UE;

Dispatch on same descending carrier the ARI in a plurality of PDCCH of transfer of data in a plurality of descending sub frames and need indicate same channel resource.

Situation four, terminal equipment determine that T channel resource of high-rise configuration is the corresponding channel resource of T bit supplementary.

Method three, this method comprise following two class resource determining method:

First kind resource determining method comprises following 2 kinds of situations:

If situation one is in M descending sub frame, terminal equipment has been received the PDCCH of the descending carrier of corresponding K configuration on downlink main carrier to carry, the PDCCH of the descending scheduling indication that PDCCH is PDSCH on the descending carrier of K configuration of transmission and/or the PDCCH that indicates semi-continuous PDSCH to discharge, terminal equipment is determined to many K channel resource according to the CCE numbering of the PDCCH of first descending sub frame of dispatching on the descending carrier of corresponding K in PDCCH configuration, as the channel resource corresponding to descending carrier of K configuration in alternative channel resource.

In such cases, if the data-bag lost of first descending sub frame of dispatching at least one descending carrier of terminal equipment judgement scheduling, terminal equipment is determined to many K dynamic channel resources according to the CCE numbering of the PDCCH of the packet receiving at least one descending carrier of scheduling, as alternative channel resource, or abandon determining the channel resource of at least one descending carrier.

Above-mentioned situation can be specially following process:

Method A, UE determine first descending sub frame (DAI dispatching on this descending carrier of scheduling _t=0 subframe) K at the most the dynamic channel resource that the CCE numbering of PDCCH is determined, K≤L, if UE judges data-bag lost in first descending sub frame (passing through DAI), UE can uncertain this descending carrier or the corresponding channel resource of code word or employing method B determine resource;

Situation two, terminal equipment determine that T+L-K channel resource of high-rise configuration is as the L-K being dispatched by the PDCCH transmitting on descending auxiliary carrier wave in an alternative channel resource descending auxiliary carrier wave and the corresponding channel resource of T bit supplementary.

Equations of The Second Kind resource determining method comprises following 3 kinds of situations:

Wherein, the corresponding channel resource of semi-continuous PDSCH is the indicated pre-configured channel resource of high level of TPC bit in the PDCCH of the semi-continuous PDSCH activation of indication.

Above-mentioned situation can be specially following process:

If situation two is in M descending sub frame, terminal equipment has been received the PDCCH of the descending auxiliary carrier wave of corresponding K configuration on downlink main carrier to carry, the PDCCH of the descending scheduling indication that PDCCH is PDSCH on the descending auxiliary carrier wave of K configuration of transmission, terminal equipment is determined to many K channel resource according to the CCE numbering of the PDCCH of first descending sub frame of dispatching on the descending auxiliary carrier wave of corresponding K in PDCCH configuration, as the channel resource corresponding to descending auxiliary carrier wave of K configuration in alternative channel resource.

In such cases, if the data-bag lost of first descending sub frame of dispatching at least one descending auxiliary carrier wave of terminal equipment judgement scheduling, terminal equipment is determined to many K dynamic channel resources according to the CCE numbering of the PDCCH of the packet receiving at least one descending auxiliary carrier wave of scheduling, as alternative channel resource, or abandon determining the channel resource of at least one descending auxiliary carrier wave.

Above-mentioned situation can be specially following process:

If in M descending sub frame, UE has received the PDCCH of K descending auxiliary carrier wave of scheduling on downlink main carrier to carry, described PDCCH is the PDCCH of the dynamic PDSCH on the descending auxiliary carrier wave of scheduling configuration, 1≤K≤L, UE determines the corresponding channel resource of descending carrier of this configuration as follows:

Situation three, UE determine the individual descending auxiliary carrier wave of L-K-1 and the corresponding channel resource of T bit overhead bit that T+L-K-1 channel resource of high-rise semi-static configuration is the PDCCH scheduling by transmitting on descending auxiliary carrier wave.

Need to further be pointed out that, in each above-mentioned method, if terminal equipment judges the data-bag lost of first descending sub frame of dispatching at least one descending carrier, terminal equipment is determined to many K channel resource according to the CCE numbering of PDCCH that receives first descending sub frame of data on the descending carrier of corresponding K in PDCCH configuration, as the channel resource corresponding to descending carrier of K configuration in alternative channel resource, or abandon determining the corresponding channel resource of at least one descending carrier.

In concrete enforcement scene, for the deterministic process of data-bag lost, specifically terminal equipment judges in each descending sub frame, whether there is data-bag lost according to the DAI bit of the PDCCH in each descending sub frame receiving and SPS transmission configuration (as transmission cycle).

It is pointed out that in the situation one of method four and method five, the ACK/NACK resource indication bit in PDCCH is indicated at least one pre-configured channel resource of high-level signaling;

If terminal equipment receives at least two PDSCH at least two descending sub frames of a descending auxiliary carrier wave, and at least two PDCCH that transmit the descending scheduling indication of at least two PDSCH on descending auxiliary carrier wave transmit on descending auxiliary carrier wave, and the ACK/NACK resource indication bit at least two PDCCH is indicated same channel resource.

According to actual scene needs, when the descending carrier of a configuration of terminal equipment judgement at least one descending sub frame in M descending sub frame exists PDSCH loss, terminal equipment can be abandoned determining channel resource for descending carrier.

On the other hand, the determined L+T of terminal equipment alternative channel resource, is specially PUCCHformat 1a/1b resource.

Step S504, terminal equipment, according to the feedback bits of L bit and the supplementary of T bit that generate, are selected a channel resource in definite L+T alternative channel resource, and determine a corresponding qam constellation point.

Step S505, terminal equipment are in sub-frame of uplink, and the channel resource by selecting, sends definite qam constellation point.

In actual applications, this step adopts PUCCH format 1b with channel selection transmission plan; According to ACK/NACK mapping form, L+T bit feedback bit is being selected to corresponding channel resource in L+T channel resource at the most, and select corresponding modulation symbol (4 QPSK constellation point of PUCCH format 1b), on the channel resource of selecting, send 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).

In said process, the ACK in ACK/NACK mapping form represents correctly to receive packet; NACK represents that mistake receives packet; DTX represents data-bag lost or without data packet dispatching.

Corresponding, in base station side, the above-mentioned identical rule of base station applies is carried out determining 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 be determined the situation of the data-bag lost of UE end, so, determine and may occur difference at channel resource in such cases with the processing procedure of aforesaid terminal equipment side, but, because terminal equipment side can not selected the corresponding channel resource of descending sub frame of data-bag lost (corresponding ACK/NACK feedback information be DTX) and carries 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 there will not be ACK/NACK feedback information to receive wrong situation.

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

Due to L=2, need carry out space merging to downlink main carrier to carry;

UE adopts RRC signaling pre-configured candidate's resource that individual channel resource is selected as channel;

On descending carrier 1, UE, according to DAI information judgement descending sub frame 2 packet losses, produces the DTX of 1 bit merging as feedback information; On descending carrier 2, UE without scheduling, according to the data of receiving in descending sub frame 2,3,4, produces 1 bit NACK as its feedback information according to DAI information judgement descending sub frame 1; UE, according to the descending sub frame number with dynamic PDCCH receiving, produces 2 bit supplementarys, and " 11 " in routine corresponding relation as shown in table 2 represent that UE has received 4 descending sub frames with dynamic PDCCH;

Table 2 supplementary mapping signal table

The final 4 bit feedback bits that generate of UE, adopt PUCCH format 1b with channel selection transmission plan, according to ACK/NACK mapping form, in the channel resource of 4 RRC configurations, determine corresponding channel resource, and determine corresponding modulation symbol, on selected channel resource, send corresponding modulation symbol;

Base station end:

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

According to base station is by pre-configured 4 the PUCCH format 1a/1b channel resources of RRC signaling;

4 pre-configured channel resources are detected in base station, obtain 4 bits and receive information; Due to M=4, base station front 2 bit informations of judgement are the amalgamation result of the ACK/NACK feedback information of the packet on descending carrier 1 and carrier wave 2, and rear 2 bit informations are supplementary, and judge that by supplementary UE does not exist last descending sub frame to lose; Retransmission data packet may is determined according to pooling information in base station.

While adopting method two

UE end:

Because UE has received the PDCCH of dispatching downlink main carrier and descending carrier 2 on downlink main carrier to carry, although the descending sub frame on downlink main carrier to carry 1 is SPS PDSCH, but there is corresponding dynamic PDCCH, therefore can determine according to the method A in method two or B the channel resource of downlink main carrier to carry and descending carrier 2 correspondences:

While adopting the method A in method two: because the packet of DAI=0 on downlink main carrier to carry is the packet in descending sub frame 1, UE determines that the corresponding channel resource of downlink main carrier to carry is 1 dynamic channel resource corresponding to CCE lowest number of the PDCCH of dispatching downlink main carrier ascending-descending subframes 1; Because the packet of DAI=0 on descending carrier 2 is the packet in descending sub frame 1, and this descending sub frame packet loss, UE can the corresponding channel resource of uncertain descending carrier 2 (because the feedback information of descending carrier 2 is DTX, UE can not adopt the channel resource of descending carrier 2 correspondences to send), or UE determines channel resource according to following method B;

During employing method B: be descending sub frame 1 owing to receiving first subframe of data on downlink main carrier to carry, UE determines that the corresponding channel resource of downlink main carrier to carry is 1 dynamic channel resource corresponding to CCE lowest number of the PDCCH of dispatching downlink main carrier ascending-descending subframes 1; Owing to receiving first descending sub frame of data on descending carrier 2, be descending sub frame 2, UE determines that the corresponding channel resource of descending carrier 2 is 1 dynamic channel resource corresponding to CCE lowest number of the PDCCH of dispatching downlink carrier wave 2 ascending-descending subframes 2;

Because the PDCCH of dispatching downlink carrier wave 3 is in descending carrier 3 (descending auxiliary carrier wave) transmission, the corresponding channel resource of descending carrier 3 is 1 semi-static channel resource of ARI indication of the PDCCH of dispatching downlink carrier wave 3 ascending-descending subframes;

UE determines that 1 pre-configured semi-static channel resource of RRC signaling is the corresponding channel resource of 1 bit supplementary;

On downlink main carrier to carry, UE, according to 2 descending sub frame data that receive, produces the ACK of 1 bit merging as feedback information; On descending carrier 2, UE, according to DAI judgement descending sub frame 1 packet loss, produces 1 bit DTX as feedback information; On descending carrier 3, UE, according to 2 descending sub frame data that receive, produces 1 bit NACK as feedback information; UE, according to the descending sub frame number with dynamic PDCCH receiving, produces 1 bit supplementary, and " 1 " in routine corresponding relation as shown in table 3 represents that UE has received 2 descending sub frames with dynamic PDCCH;

The final 4 bit feedback bits that generate of UE, adopt PUCCH format 1b with channel selection transmission plan, according to ACK/NACK mapping form, in 4 channel resources, determine corresponding channel resource, and determine corresponding modulation symbol, on selected channel resource, send corresponding modulation symbol;

During employing method three

UE end:

Because UE has received the PDCCH of dispatching downlink main carrier and descending carrier 2 on downlink main carrier to carry, although the descending sub frame on downlink main carrier to carry 1 is SPS PDSCH, but there is corresponding dynamic PDCCH, therefore can determine according to the method A in method two or B the channel resource of downlink main carrier to carry and descending carrier 2 correspondences: concrete grammar is with the description in situation 1 method two;

Because the PDCCH of dispatching downlink carrier wave 3 transmits at descending carrier 3 (descending auxiliary carrier wave), be that descending carrier 3 does not exist corresponding dynamic channel resource, UE determines that 2 pre-configured semi-static channel resources of RRC signaling are descending carrier 3 and the corresponding channel resource of 1 bit supplementary;

UE produces the mode of feedback bits as described in method two;
