Fig. 2 shows the method flow diagram in base station according to an embodiment of the invention.

Wherein, same or analogous reference represents same or analogous steps characteristic or device/module.

Specific embodiment

In order to support the TDD with carrier aggregation between different configuration of different frequency bands (Carrier Aggregation, CA) , PUCCH format 1b combined channel select pattern, applicant propose reuse version 10, for PUCCH format 1b combined channel The mapping table of selection pattern, does not introduce new mapping table.From from the point of view of handling capacity, by keeping different M values, energy for cell Enough avoid unnecessary bindings.

It is appreciated that uplink feedback subframe, represent according to TDD uplink-downlink configurations information and HARQ feedback sequential (see TS36.213 Table 10.1.3.1-1:Downlink association set index K:{k0, k1... kM-1}for TDD), for transmitting the PUCCH subframes of ACK/NACK.

Fig. 1 shows the method flow diagram in the user terminal of a specific embodiment of the invention.First, in step In rapid S10, the number of the feedback main plot PDSCH transmission subframe that user terminal is carried in the subframe according to main plot PUCCH With feedback from the relation between the number of cell PDSCH transmission subframe, it is determined whether need to main plot and/or from cell The feedback of PDSCH transmission subframe carries out time domain binding or space is bound, and carried in the subframe to the PUCCH of main plot Need to carry out the time domain binding main plot that either space is bound and/or carry out time domain binding or sky from the PDSCH feedbacks of cell Between bind, with formed through time domain binding or through space binding feedback.

In order to meet these demands, A/N bit maps need to be modified, to support CA between CC specific different frequency bands PUCCH format 1b of TDD.Here different (Mp, the Ms) to main plot and from cell, Mp ≠ Ms are considered.User terminal according to Relation between Mp and Ms, needs the operation for carrying out following three type.

Operation 1:

- judge to be needed in the uplink feedback subframe main plot fed back or the PDSCH subframes from cell when user terminal Number be equal to 1 when, judge need feedback number be equal to 1 PDSCH subframes in code word number;

- when the number of the code word that the number for needing to feed back is equal in 1 PDSCH subframes is equal to 2, to described 2 The feedback of code word carries out spatial domain binding, to form 1 bit feedback position;

1 bit negative feedback is added behind the 1 bit feedback position or discontinuous transmission is indicated, to form the anti-of 2 bits Feedforward information.

Specifically, 1 is equal in Mp or Ms, and during another Ms or Mp > 1, if the CC (Mp=1 with Mp or Ms=1 When, corresponding to main plot, during Ms=1, corresponding to from cell) on corresponding PDCSH subframes exist two code words, then carry out Space is bound, and otherwise, if PDSCH only exists a code word, the A/N of a code word is remained into a bit.Then, one Individual NACK/DTX bits will be attached to behind ACK/NACK bits, and so, the A/N of the CC defines 2 bit status, be used for into One step is mapped with the CC of Ms or Mp > 1.

Operation 2:

When user terminal judges to be needed in the uplink feedback subframe main plot fed back or from the PDSCH subframes of cell When number is more than 2, according to feedback number, to feeding back main plot of the number more than 2 or tying up from the uplink feedback time of carrying out of cell It is fixed, with the feedback that the elapsed time for forming 2 bits binds.

For example, when Mp or Ms is more than 2, time domain binding is carried out based on the actual M values of target CC, rather than as version 10 Use unified M for multiple CC like that.In an embodiment of the present invention, the time domain for using binds form and defined in version 10 As, therefore 3 or 4 A/N bits are also mapped onto the state of 2 bits.

Operation 3:

When the main plot for needing to feed back in the uplink feedback subframe that user terminal judges main plot or from cell PDSCH subframe When number is 0, the non-zero main plot of number is fed back or from cell using PUCCH format 1a or 1b joints/non-joint letter to another Road selects pattern that feedback is transmitted in the way of single carrier.

For example, in PCC or SCC without in the case of A/N, being shown as Mp or Ms=0, PUCCH format 1a/1b joint/ Combined channel does not select pattern to be considered 1-4 A/N bit of transmission, as single CC.

Table one shows each pair (Mp, Ms), specific one needed for Mp ≠ Ms combinations or multiple operations.

According to table one, the PDSCH number of sub-frames when feedback main plot or from cell is another with the feedback on the uplink feedback The number of one cell PDSCH subframe for (1,2) combine when, that is, (Mp, Ms) for (1,2) or (2, when 1), need to feedback PDSCH number of sub-frames is that 1 A/N carries out operation 1.

When feedback another cell in feedback main plot or PDSCH number of sub-frames from cell with the uplink feedback The number of PDSCH subframes for (2,3) or (2,4) or (3,4) combine when, that is, (Mp, Ms) for (2,3), (2,4), (3,4), (3,2), (4,2) or (4, when 3), need to need to carry out operation 2 to feeding back the A/N of PDSCH number of sub-frames more than 2.

When feedback another cell in feedback main plot or PDSCH number of sub-frames from cell with the uplink feedback The number of PDSCH subframes for (1,3) or (Isosorbide-5-Nitrae) combine when, that is, (Mp, Ms) for (1,3), (Isosorbide-5-Nitrae), (3,1), (4, when 1), Need to carry out operation 1 to feeding back the A/N that PDSCH number of sub-frames is 1, need to feeding back A/N of the PDSCH number of sub-frames more than 2 in addition Carry out operation 2.

When feedback another cell in feedback main plot or PDSCH number of sub-frames from cell with the uplink feedback Being combined as of the number of PDSCH subframes (0,1), (0,2), (0,3) or, (0, when 4) combining, namely (Mp, Ms) for (0,1), (0, 2), (0,3), (0,4), (1,0), (2,0), (3,0) or (4,0), adopt to another non-zero main plot of feedback number or from cell Select pattern that feedback is transmitted in the way of single carrier with PUCCH format 1a or 1b joints/non-combined channel.

For specifically (Mp, Ms), Mp ≠ Ms combinations are carried out after above operation, further considering that reusing version 10 defines Suitable mapping table, and do not introduce new time-scale.

Therefore, in step s 11, user terminal binds this or through space binding according to mapping table through time domain Feedback bits be mapped as feedback result.Then, in step s 12, to feedback result described in base station feedback.

Situation A:When the feedback in feedback main plot or PDSCH number of sub-frames from cell with the uplink feedback another Being combined as of the number of cell PDSCH subframe (1,2), (1,3), (Isosorbide-5-Nitrae), (2,3), (2,4) in any one when, user terminal 2 are equal to according to M, the feedback that elapsed time binding or space are bound is reflected with the feedback of another cell PDSCH subframe of the feedback In being incident upon PUCCH format 1b combined channel selection pattern, wherein, M represent the feedback main plot that carried in the subframe of PUCCH and From the number of cell PDSCH transmission subframe.

For operation 1 and/or operation 2 in form 1 based on main plot is used for and from cell, the A/N shapes of 2 bits are obtained State.These combination include (Mp, Ms) for (1,2), (2,1), (2,3), (2,4), (3,2), (4,2), (1,3), (Isosorbide-5-Nitrae), (3, 1), (4,1).Therefore the PUCCH format 1b combined channel for further carrying out the M=2 for two CC selects the A/N bits of pattern Mapping, as shown in the form 10.1.3.2-3 and 10.1.3.2-4 of 3GPP TS 36.213 in version 10.

Situation B:When the feedback in feedback main plot or PDSCH number of sub-frames from cell with the uplink feedback another The combination of the number of cell PDSCH subframe is that (3, when 4), user terminal is equal to 3 according to M, by the process of 2 bit The feedback of temporal binding maps to PUCCH format 1b combined channel with 2 bit feedbacks of another cell PDSCH subframe of the feedback In selection pattern, wherein, M represents the feedback main plot carried in the subframe of PUCCH and from the individual of cell PDSCH transmission subframe Number.

In Table 1 (Mp, Ms)=(3,4) or (4,3) in the case of, two CC are based respectively on different forms for M= 3 or M=4 carry out different time domain bindings, then reuse the form for M=3 in the 3GPP TS 36.213 of version 10 10.1.3.2-5, to avoid unnecessary binding, and while keep enough effective statuses, to obtain good performance.

Situation C:Without in the case of A/N bit transfers in a CC, these (Mp, Ms) can include (0,1), (0, 2), (0,3), (0,4), (1,0), (2,0), (3,0) or (4,0).In order to simplify technical scheme, the A/N bits of another CC can To be transmitted by PUCCH 1a/1b joint/non-joint (w/o, with/without) Channel assignments, the 3GPP TS with version 10 For the identical of list CC in 10.1.3.1 sections in 36.213.

How sharp under conditions of carrier aggregation between the different frequency bands with different uplink-downlink configurations will be given below Several specific examples of transmission HARQ-ACK/NACK are selected with PUCCH1b combined channels.

For situation A, for example (Mp, Ms)=(2,1), if for SCC has two code words, carrying out space binding so that A/N for a most bit in a PDSCH subframe is fed back, and otherwise keeps an A/N bit for a code word.Then, A NACK/DTX bit is added behind the A/N bits.

Next, according to the table 10.1.3.2-4 of 3GPP TS 36.213, by its two other A/N with the PCC of Mp=2 Bit joint consider, by the feedback on each Serving cell be mapped to M=2, for PUCCH format 1b combined channel select On the HARQ-ACK (j) of pattern, and reuse form 10.1.3.2-3 and carry out final A/N bit maps.

The reason for carrying out space binding and an additional NACK/DTX bit for SCC is for version 10 in current definition M=1 mapping form in, as shown in the form 10.1.2.2.1-1 in 3GPP TS 36.213, for the A/N of two code words Bit is considered, and as the M=2 as shown in form 10.1.3.2-4, the A/N bits after the binding of space are considered, this be due to The restriction of most 4 bit feedbacks of pattern is selected for PUCCH format 1b combined channel.Additionally, in prior art, not existing The feedback of 2 code words of a DL subframe (descending sub frame, namely PDSCH) for a CC is considered across and for another The form of the feedback of two PDSCH subframes with space binding of CC.

For example, for (Mp, Ms)=(2,3), 3 A/N bits should be mapped to a dibit shape by time domain binding In state, as shown in the following table two used in version 10.HARQ-ACK (0) is represented to the anti-of the 1st PDSCH subframe in table two Feedback, HARQ-ACK (1) represents feedback to the 2nd PDSCH subframe, and HARQ-ACK (2) is represented to the anti-of the 3rd PDSCH subframe Feedback.Then, identical with example above, next four A/N bits are mapped to PUCCH format 1b combined channel and select pattern On, the M=for two CC based on the form 10.1.3.2-3 in the 3GPP TS 36.213 of version 10 and 10.1.3.2-4 2。

For situation C, in the case where PCC or SCC do not have A/N bits, for sake of simplicity, proposing 1 to 4 A/N bit Be mapped to PUCCH 1a/1b joints or non-combined channel selected, such as in 10.1.3.1 is saved by single service CC define that Sample.Based on high-level signaling, being configured with the UE of single Serving cell will perform Channel assignment, according to 10.1.3-2,10.1.3-3, With the sets of tables of 10.1.3-4, or according to the sets of tables of 10.1.3-5,10.1.3-6, with 10.1.3-7.

Hereinafter, with reference to Fig. 2, the method flow diagram in base station according to the second embodiment of the present invention is described.It is first First, in step S20, base station receives the ACK/NACK feedback results for carrying out user terminal.Then, in the step s 21, base station root It is to main plot and from cell through time domain binding or through space binding by the feedback result inverse mapping according to mapping table On PDSCH transmission subframe feedback.Then, in step S22, what base station was carried in the subframe according to main plot PUCCH Main plot and the number and code word number of the feedback from cell PDSCH transmission subframe, bind described or pass through through time domain The feedback decoding of the PDSCH transmission subframe to main plot and from cell of space binding is that the user terminal is little to the master Area and the feedback from cell.

Base station has already known number of the user terminal to the scheduling of the PDSCH subframes of the PDSCH subframes and SCC of PCC, because Know the configuration mode of the up-downgoing of the PCC in TDD and SCC in base station.

Therefore, in the step s 21, feed back in the number and this of the main plot or the PDSCH subframes from cell Row feedback on feedback another cell PDSCH number of sub-frames combination be (1,2), (1,3), (Isosorbide-5-Nitrae), (2,3), (2,4) in Any one when, step S21 also includes:2 mapping table is equal to according to M, PUCCH format 1b combined channel is selected into pattern solution The feedback of the binding of mapping elapsed time or space binding and the feedback of another cell PDSCH subframe of the feedback, wherein, M is represented The feedback main plot carried in the subframe of PUCCH and the number from cell PDSCH transmission subframe.

Alternatively, when in the number and the uplink feedback of the feedback main plot or the PDSCH subframes from cell The combination of number of feedback another cell PDSCH subframe be that (3, when 4), step S21 also includes:Base station is equal to 3 according to M Mapping table, by PUCCH format 1b combined channel the anti-of the elapsed time binding that the feedback demapping of pattern is 2 bits is selected 2 bit feedbacks with another cell PDSCH subframe of the feedback are presented, wherein, M represents the feedback carried in the subframe of PUCCH Main plot and the number from cell PDSCH transmission subframe.

Then, in step S22, because the number of the PDSCH subframes being scheduled known to base station, and in PDSCH subframes Comprising code word number, so as to base station is according to above-mentioned number of sub-frames and code word number, solution binding is carried out to feedback information.

For example, when main plot is carried in the subframe of the PUCCH of main plot or from the number of the feedback of cell 1 is equal to, and When the number of the main plot or the codeword feedback to carrying in the subframe of the PUCCH from cell is 2, solution is carried out to the feedback empty Between bind, with obtain for each code word feedback.

Or, when the main plot and the feedback from cell that carry in the main plot PUCCH subframes When number is more than 2, the main plot or the feedback carried from cell to the feedback number more than 2 carries out the solution time Binding, to form the feedback.

Or, when the main plot and the feedback from cell that carry in the main plot PUCCH subframes When number is 0, the pattern main plot non-zero to another feedback number is selected according to PUCCH format 1a or 1b joints/non-combined channel Or decoded from the feedback of cell.

Generally speaking, embodiments of the invention have reused the mapping table for the definition of version 10, any new without introducing Mapping table.In the case where each CC has different binding window sizes, for superperformance, embodiments of the invention are being kept away The acquirement for exempting from unnecessarily to bind and keep trying one's best between many effective statuses is balanced.
