Change, in the second moment, Serving cell has switched to cell 2 by cell 1, and assistant service cell has switched to cell 1 by cell 2.
After the attribute switching of cell 1 and cell 2 finishes, the chnnel coding order of terminal unit is changed into: 1, the corresponding feedback letter of cell 2
Breath --- -2, the corresponding feedback information of cell 1, for example: the corresponding feedback information of cell 2 is cqi0, the corresponding feedback letter of cell 1
Cease for cqi1.Likewise, base station equipment is also required to the chnnel coding order of institute's foundation is switched over, to be allowed to and terminal unit
Identical, thus ensureing base station equipment after the decoding, the correct cell corresponding to information determining coded by terminal unit.
But, in the prior art, when there is cell asynchronised handover in terminal unit and base station equipment, period terminal unit
Still may need to base station equipment feedback information.Now, it is located if there being a side not complete in base station equipment or terminal unit
The attribute switching of cell, then terminal unit is suitable with the chnnel coding of base station equipment institute foundation to the chnnel coding order of feedback information
Difference occurs for sequence so that base station equipment can not correctly determine the cell corresponding to information coded by terminal unit, occurs anti-
Out of order the led to high level data of feedforward information retransmits, repeats the problems such as transmit and dispatch improper, in this case, base station equipment
Generally require to expend extra system resource and again transmit the data ging wrong, for example: base station equipment can be again to terminal unit
Send the correctly received data of terminal unit, thus causing the waste of system resource.

Advantage for making technical solution of the present invention is clearer, with reference to the accompanying drawings and examples the present invention is made specifically
Bright.
Embodiment 1
The embodiment of the present invention provides a kind of information feedback method, as shown in Figure 2, comprising:
The present embodiment is based on multiple stream transmission technology.
S201, the type of the cell that terminal unit identification is currently located.
Wherein, the type of cell includes timing reference cell and non-timed reference cell.
In the present embodiment, terminal unit can be currently located cell by existing technological means identification terminal equipment is
Timing reference cell or non-timed reference cell, for example: terminal unit can receive the rnc (radio in existing communication system
Network controller, radio network controller) the signaling instruction that issues, and which cell is known that according to this instruction
It is timing reference cell, and others are exactly non-timed reference cell.
S202, the type of the cell being currently located according to described terminal unit, determine chnnel coding order.
Wherein, chnnel coding order includes: timing reference cell prioritization is before non-timed reference cell.
For example:
Shown in table one is in existing 3gpp agreement, non-mimo (the multiple input of the sf-dc+ in mf-tx
Multiple output, multiple-input and multiple-output) (i.e. under this scene, co-exist in two cells and carry out with terminal unit under scene
Data interaction, one of them is serving hs-dsch cell, and another is assisting serving hs-dsch
Cell, and neither one cell is in mimo pattern) chnnel coding order.
Table one
Wherein, what " a0 " and " cqi0 " represented is harq-ack information and the cqi information of timing reference cell；" a1 " and
What " cqi1 " represented is harq-ack information and the cqi information of non-timing reference cell.I.e. chnnel coding order is: encodes first
The harq-ack information of timing reference cell and cqi information, the harq-ack information of re-encoding non-timed reference cell and cqi letter
Breath.
Again for example:
Shown in table two is in existing 3gpp agreement, (i.e. in this scene under the sf-dc+mimo scene in mf-tx
Under, co-exist in two cells and carry out data interaction with terminal unit, one of them is serving hs-dsch cell, another
Be assisting serving hs-dsch cell, and at least one cell be in mimo pattern) chnnel coding suitable
Sequence.
Table two
Wherein, what " a0 " and " pci/cqi0 " represented is harq-ack information and the pci/cqi information of timing reference cell；
What " a1 " and " pci/cqi1 " represented is harq-ack information and the pci/cqi information of non-timing reference cell.I.e. chnnel coding
Order is: the harq-ack information of coding timing reference cell and pci/cqi information first, re-encoding non-timed reference cell
Harq-ack information and pci/cqi information.
S203, according to described chnnel coding order, carries out chnnel coding to sent information.
Wherein, information to be sent includes: the feedback information corresponding to each cell that described terminal unit is currently located,
For example: harq-ack information and cqi information etc..
It should be noted that terminal unit, according to described chnnel coding order, carries out chnnel coding to sent information
Specific embodiment can be any-mode well-known to those skilled in the art, will not be described here.
S204, sends the information described to be sent that have passed through chnnel coding to base station equipment.
It should be noted that the difference of the embodiment of the present invention and prior art maximum is: the embodiment of the present invention being capable of root
To determine feedback information (such as: harq-ack information and cqi/pci letter according to the timing reference of cell and the attribute of non-timed reference
Breath) chnnel coding order；And prior art to be attribute based on Serving cell and assistant service cell to determine to send feedback
The chnnel coding order of information.
In the prior art, terminal unit determines whether to switch each according to the attribute of Serving cell and assistant service cell
The attribute of cell simultaneously changes the order of send feedback information, the position in the wireless network depending on terminal unit or each little
The channel circumstance in area.Can often move during due to user's using terminal equipment, the channel circumstance of each cell also can change, institute
To occur the probability that Serving cell switches very high, once Serving cell switching switches, then Serving cell and assistant service are little
The attribute in area necessarily switches, and the chnnel coding order of the feedback information such as harq-ack information and cqi/pci information must
So can change so that in actual applications, terminal unit needs to be frequently changed the order of send feedback information, result is made
Out of order the led to high level data of feedback information is become to retransmit, repeat the problems such as transmit and dispatch improper.Base station and terminal are set
Standby need to take the system resources such as extra calculation resources, channel resource, to the data corresponding to the feedback information of loading error occurring
The remedial process it is evident that causing the waste of system resource such as again transmitted.
In comparison, whether switch between timing reference cell and non-timed reference cell, between cell
Whether timing difference exceeds certain limit.The change of timing difference is mainly 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 very little
In the range of, then there is the timing reference of cell and the switching probability very little of non-timed reference attribute, or even a long period
Substantially will not switch in section.
So, compared with prior art, due to the switching frequency of timing reference cell/non-timed this attribute of reference cell
And infrequently so that base station equipment and terminal unit can with identical chnnel coding sequential working, and be not required to continually change
Become chnnel coding order, thus decreasing base station equipment and terminal unit carries out the probability of asynchronised handover so that energy of the present invention
, to during base station equipment feedback of the information, feedback information out of order led in enough reduction terminal units when cell switches
High level data retransmits, repeats the probability of the problems such as transmit and dispatch improper, saves system resource.

In the present embodiment, s302 may include that
S3021, determines the group belonging to non-timed reference cell that described terminal unit is currently located.
Wherein, the quantity of the non-timed reference cell that terminal unit is currently located is more than or equal to 2.
In the present embodiment, terminal unit can be by default little for the timing reference under each scene in mf-tx
The packet relation of area/non-timed reference cell, determines the group belonging to non-timed reference cell that terminal unit is currently located.Example
As:
Shown in table three and table four all be in existing 3gpp agreement, (dual freq terminal sets the df-3c in mf-tx
Standby ncy 3cell dual carrier three cell) chnnel coding order under+non-mimo scene.
Specifically, this scene is also divided into two kinds of situations:
1) timing reference cell place group contains two cells altogether:
Table three
I.e. in table three, non-timed reference cell with timing reference cell in a group (group 1), wherein,
Cell 0 corresponds to timing reference cell；Non-timed reference cell in the group of cell 1 corresponding timing reference cell place；cell 2
The non-timed reference cell of (group 2) in corresponding remaining group.
2) timing reference cell place group contains a cell altogether:
Table four
I.e. in table four, timing reference cell individually in a group, other non-timed reference cell in another set,
Wherein, cell 0 corresponds to timing reference cell；A non-timed reference cell in the corresponding remaining group of cell 1；Cell 2 is corresponding
Another non-timed reference cell in remaining group.
Again for example:
Shown in table five and table six all be letter in existing 3gpp agreement, under the df-3c+mimo scene in mf-tx
Road coded sequence.
Specifically, this scene is also divided into two kinds of situations:
1) timing reference cell place group contains two cells altogether:
Table five
I.e. in table five, cell 0 corresponds to timing reference cell；Non- in the group of cell 1 corresponding timing reference cell place
Timing reference cell；Non-timed reference cell in the corresponding remaining group of cell 2.
2) timing reference cell place group contains a cell altogether:
Table six
I.e. in table six, cell 0 corresponds to timing reference cell；Non-timed reference cell in the corresponding remaining group of cell 1；
Non-timed reference cell in the corresponding remaining group of cell 2.
Again for example:
Shown in table seven is in existing 3gpp agreement, df-4c (the dual freq terminal unit ncy in mf-tx
3cell dual carrier four cell) chnnel coding order under+non-mimo scene.
Table seven
I.e. in table seven, cell 0 corresponds to timing reference cell；Non- in the group of cell 1 corresponding timing reference cell place
Timing reference cell；Non-timed reference cell in the corresponding remaining group of cell 2；Non-timed ginseng in the corresponding remaining group of cell 3
Examine cell.
Again for example:
Shown in table eight is in existing 3gpp agreement, and the chnnel coding under the df-4c+mimo scene in mf-tx is suitable
Sequence.
Table eight
I.e. in table eight, cell 0 corresponds to timing reference cell；Non- in the group of cell 1 corresponding timing reference cell place
Timing reference cell；Non-timed reference cell in the corresponding remaining group of cell 2；Non-timed ginseng in the corresponding remaining group of cell 3
Examine cell.
S3022, the non-timed reference cell in each group is arranged in order according to carrier wave order.
In the present embodiment, terminal unit can according to carrier wave order by the non-timed reference cell in each group successively
Arrangement, for example: under the df-4c+mimo scene shown in table eight, terminal unit can according to carrier wave order by group 2 this
This two non-timed reference cell of cell 2 in group and cell 3 are arranged in: cell 2 → cell 3.In the same manner, in mf-tx
Under other scenes, terminal unit can also by same procedure by the non-timed reference cell in each group according to carrier wave order according to
Secondary arrangement.
Further, due in actual applications, the packet situation of reference cell has two kinds it may be assumed that 1, timing reference cell
There is at least one non-timed reference cell in the group of place；2nd, there is not the non-timed in the group of timing reference cell place with reference to little
Area.Then s3022 can include two kinds of flow processs arranged side by side:
First, as shown in Figure 3 b, when there is at least one non-timed reference cell in the group of timing reference cell place:
Timing reference cell place group is set as the 1st group of group1, then the non-timed reference cell in each group is pressed
