In Fig. 1, cell 1 is serving cell(Serving HS-DSCH cell), cell 2 is auxiliary serving cell( assisting serving HS-DSCH cell ).Then the channel coding order of terminal device is:The corresponding feedback information of the corresponding feedback information cell 2 of cell 1, for example:The corresponding feedback information of cell 1 is CQI0, and the corresponding feedback information of cell 2 is CQI1.Base station equipment is decoded after the feedback information of terminal device transmission is received, and according to the channel coding order of terminal device, determine such as CQI (the Channel Quality Indicator coded by terminal device, channel quality is indicated), the cell corresponding to the information such as HARQ-ACK (Hybrid Automatic Repeat Request- Acknowledgement, hybrid automatic repeat-request-confirmation).

But, in the prior art, when cell asynchronised handover occurs for terminal device and base station equipment, during which terminal device still may be needed to base station equipment feedback information.Now, if there is a side not complete the attribute switching of place cell in base station equipment or terminal device, then difference occurs to the channel coding order of the channel coding of feedback information order and base station equipment institute foundation in terminal device, prevent base station equipment is from correctly determining the cell corresponding to the information coded by terminal device, there is the problems such as out of order caused high level data of feedback information retransmits, repeats to transmit and dispatch improper, in this case, base station equipment generally requires the extra system resource of consuming and transmits the data gone wrong again, for example:Base station equipment can send the correctly received data of terminal device to terminal device again, so as to cause the waste of system resource.

Embodiment 1
The embodiment of the present invention provides a kind of information feedback method, as shown in Fig. 2 including:
The present embodiment is based on multiple stream transmission technology.
5201, the type for the cell that terminal device identification is currently located.
Wherein, the type of cell includes timing reference cell and non-timed reference cell.
In the present embodiment, it is timing reference cell or non-timed reference cell that terminal device can be currently located cell by existing technological means identification terminal equipment, for example:Terminal device can receive RNC (Radio Network Controller, radio network controller in existing communication system)The signaling issued is indicated, and is known which cell is timing reference cell according to the instruction, and others are exactly non-timed reference cell.
5202, the type for the cell being currently located according to the terminal device determines channel coding order.Wherein, channel coding order includes:Timing reference cell prioritization is in non-timed reference cell Above.
For example:
During shown in table one is existing 3GPP agreements, under the non-MIMO of SF-DC+ (Multiple Input Multiple Output, multiple-input and multiple-output) scene in MF-Tx(I.e. under the scene, co-exist in two cells and carry out data interaction with terminal device, one of them isservinG HS-DSCH cell, another is assisting serving HS-DSCH cell, and neither one cell is in MIM0 patterns)Channel coding order.
Table one
Wherein, what " AO " and " CQIO " was represented is the HARQ-ACK information and CQI information of timing reference cell;" Α Γ, and " CQI1 " represent be non-timing reference cell HARQ-ACK information and CQI information.I.e. channel coding is sequentially:The HARQ-ACK information and CQI information of timing reference cell, the HARQ-ACK information and CQI information of re-encoding non-timed reference cell are encoded first.
Again for example:
During shown in table two is existing 3GPP agreements, under the SF-DC+ MIMO scenes in MF-Tx(I.e. under the scene, co-exist in two cells and carry out data interaction with terminal device, one of them is serving HS-DSCH cell, and another is assisting serving HS-DSCH cell, and At least one cell is in MIMO mode)Channel coding order.
Table two
Wherein, what " AO " and " PCI/CQIO " was represented is the HARQ-ACK information and PCI/CQI information of timing reference cell;What " A1 " and " PCI/CQI1 " was represented is the HARQ-ACK information and PCI/CQI information of non-timing reference cell.I.e. channel coding is sequentially:The HARQ-ACK information and PCI/CQI information of timing reference cell, the HARQ-ACK information and PCI/CQI information of re-encoding non-timed reference cell are encoded first.
5203, according to channel coding order, channel coding is carried out to sent information.
Wherein, information to be sent includes:The feedback information corresponding to each cell that the terminal device is currently located, for example:HARQ-ACK information and CQI information etc..
It should be noted that terminal device is according to channel coding order, the embodiment that channel coding is carried out to sent information can be any-mode well-known to those skilled in the art, will not be repeated here.
5204, the information to be sent that have passed through channel coding is sent to base station equipment.
It should be noted that the embodiment of the present invention and the maximum difference of prior art are:The embodiment of the present invention can determine feedback information according to the timing reference of cell and the attribute of non-timed reference(Such as: HARQ-ACK information and CQI/PCI information)Channel coding order;And prior art be based on serving cell and the attribute of assistant service cell come determine send feedback information channel coding order.
In the prior art, terminal device determines whether to switch the attribute of each cell and changes the order of send feedback information according to the attribute of serving cell and assistant service cell, position in the wireless network or the channel circumstance of each cell depending on terminal device.Can often it be moved during due to user's using terminal equipment, the channel circumstance of each cell can also change, so the probability for occurring serving cell switching is very high, once serving cell switching switches, then serving cell and the attribute of assistant service cell necessarily switch, the channel coding order of the feedback information such as HARQ-ACK information and CQI/PCI information will necessarily change, so that in actual applications, terminal device needs to be frequently changed the order of send feedback information, as a result the out of order caused high level data of feedback information is caused to retransmit, the problems such as repetition is transmitted and dispatches improper.So that base station and terminal device need to take the system resources such as extra calculation resources, channel resource, to the feedback letter of loading error occurring, corresponding data carry out the remedial processing such as transmission again, it is evident that cause the waste of system resource.
In comparison, whether switch between timing reference cell and non-timed reference cell, whether exceed certain limit depending on the timing difference between cell.The change of timing difference is main as caused by crystal oscillator frequency difference in cell own base station equipment, due to can periodically do timing alignment between base station equipment, can be with the change of timing difference between basic guarantee cell in the range of very little, the timing reference and non-timed for then occurring cell refer to the switching probability very little of attribute, or even will not be switched substantially in a longer period. So, compared with prior art, due to the switching frequency and infrequently of timing reference cell/non-timed this attribute of reference cell, base station equipment and terminal device allow with identical channel coding sequential working, and it is not required to be frequently changed channel coding order, the possibility of asynchronised handover is carried out so as to reduce base station equipment and terminal device, allow the invention to reduction when cell switches terminal device to during base station equipment feedback of the information, there is the out of order caused high level data of feedback information to retransmit, the probability for the problems such as repetition is transmitted and dispatches improper, save system resource.
Embodiment 2
The embodiment of the present invention provides a kind of information feedback method, as shown in Figure 3 a, including:
The present embodiment is based on multiple stream transmission technology.
5301, the type for the cell that terminal device identification is currently located.
Wherein, the type of cell includes timing reference cell and non-timed reference cell.
5302, the type for the cell being currently located according to the terminal device determines channel coding order.Wherein, channel coding order includes:Timing reference cell comes the first place of all cells all the time.In the present embodiment, S302 can include:
S3021, group of the non-timed for determining that the terminal device is currently located belonging to reference cell.Wherein, terminal device be currently located non-timed reference cell quantity be more than or equal to 2.
In the present embodiment, terminal device can be by the packet relation of default timing reference cell under each scene in MF-Tx/non-timed reference cell, group of the non-timed for determining that terminal device is currently located belonging to reference cell.For example: Shown in table three and table four all be existing 3GPP agreements, channel coding order under DF-3C (cell of 3 Cell dual carriers of Dual Freq terminal devices ncy three)+non-MIMO scene in MF-Tx.
Specifically, the scene is also divided into two kinds of situations:
1) group where timing reference cell is altogether containing two cells:
Table three
I.e. in table three, one the non-timed reference cell with timing reference cell in a group(Group 1), wherein, the corresponding timing reference cells of cell 0;Non-timed reference cell where the correspondences of cell 1 timing reference cell in group;In the remaining group of the correspondences of cell 2(Group 2) non-timed reference cell.
2) group where timing reference cell is altogether containing a cell:
Table four
I.e. in table four, timing reference cell individually in a group, other non-timed reference cell in another set, wherein, the corresponding timing reference cells of cell 0;In the remaining group of the correspondences of cell 1 one the non-timed reference cell;Another reference cell in the remaining group of the correspondences of cell 2 non-timed.
Again for example:
Shown in table five and table six all be existing 3GPP agreements, the DF-3C+ in MF-Tx Channel coding order under MIMO scene.
Specifically, the scene is also divided into two kinds of situations:
1) group where timing reference cell is altogether containing two cells:
Table five
I.e. in table five, cell O correspondences timing reference cell;Non-timed reference cell where the correspondences of cell 1 timing reference cell in group;Non-timed reference cell in the remaining group of the correspondences of cell 2.
2) group where timing reference cell is altogether containing a cell:
Table six
I.e. in table six, cell O correspondences timing reference cell;Non-timed reference cell in the remaining group of the correspondences of cell 1;Non-timed reference cell in the remaining group of the correspondences of cell 2.
Again for example:
During shown in table seven is existing 3GPP agreements, the DF-4C (cells of 3 Cell dual carriers of Dual Freq terminal devices ncy four in MF-Tx)Channel coding order under+non-MIMO scene.

Again for example:
During shown in table eight is existing 3GPP agreements, the channel coding order under the DF-4C+MIMO scenes in MF-Tx.
Table eight is i.e. in table eight, the corresponding timing reference cells of cell 0;Non-timed reference cell where the correspondences of cell 1 timing reference cell in group;Non-timed reference cell in the remaining group of the correspondences of cell 2;Non-timed reference cell in the remaining group of the correspondences of cell 3.
S3022, the non-timed reference cell in each group is arranged in order according to carrier wave order.
In the present embodiment, terminal device can refer to the non-timed in each group according to carrier wave order Cell is arranged in order, for example:Under the DF-4C+MIMO scenes shown in table eight, terminal device can according to carrier wave order by the cell 2 and cell 3 in Group 2 this group this two the non-timed reference cell be arranged in: cell 2 cell 3.Similarly, in MF-Tx under other scenes, the non-timed reference cell in each group can also be arranged in order by terminal device by same procedure according to carrier wave order.
Further, because in actual applications, the packet situation of reference cell has two kinds, i.e.,:1st, there is at least one reference cell where timing reference cell in group non-timed;2nd, non-timed reference cell is not present where timing reference cell in group.Then S3022 can include two kinds of flows arranged side by side:First, as shown in Figure 3 b, when there is at least one non-timed reference cell in group where timing reference cell:
Group where timing reference cell is set as the 1st group of Groupl, then the non-timed reference cell in each group is arranged in order according to carrier wave order and can included:
530221, by the non-timed reference cell in the 1st group of Groupl, the 1st position, the 2nd position are arranged sequentially until M positions according to carrier wave.
530222, by the non-timed reference cell in the 2nd group of Group2, M+1 positions, M+2 positions are sequentially arranged in until M+N positions according to carrier wave order.
Similarly, repeat S30221 to S30222 flow, until by the non-timed reference cell in Group X, Y location, Y+1 positions are sequentially arranged in up to Z location according to carrier wave order, so that the non-timed reference cell that all terminal devices are currently located is arranged in order according to carrier wave order.
It should be noted that M, N and X are the positive integer more than 0, Y is equal to last in X-1 groups Position number+1, Z is more than or equal to bifurcation.
Second, as shown in Figure 3 c, when non-timed reference cell is not present in group where timing reference cell:Group where timing reference cell is set as the 1st group of Groupl, then the non-timed reference cell in each group is arranged in order according to carrier wave order and can included:
530223, by the non-timed reference cell in the 1st group of Groupl, the 1st position, the 2nd position are arranged sequentially until M positions according to carrier wave.
530224, by the non-timed reference cell in the 2nd group of Group2, M+1 positions, M+2 positions are sequentially arranged in until M+N positions according to carrier wave order.
Similarly, repeat S30223 to S30224 flow, until by the non-timed reference cell in Group X, Y location, Y+1 positions are sequentially arranged in up to Z location according to carrier wave order, so that the non-timed reference cell that all terminal devices are currently located is arranged in order according to carrier wave order.
It should be noted that M, N and X are the positive integer more than 0, Y is equal to rearmost position sequence number+1 in X-1 groups, and Z is more than or equal to bifurcation.
S3023, the non-timed reference cell by arrangement is arranged in behind timing reference cell.In the present embodiment, no matter the non-timed reference cell how to arrange, terminal device all the time comes timing reference cell the first place of all cells all the time, for example:As shown in Table 8, when terminal device is encoded according to channel coding order to feedback information, the information that timing reference cell corresponds to the PCI/CQI0 in existing protocol all the time and other suffix numbering is " 0 ".
S303, according to channel coding order, channel coding is carried out to sent information. Wherein, information to be sent includes:The feedback information corresponding to each cell that the terminal device is currently located.
S304, the information to be sent that have passed through channel coding is sent to base station equipment.
