Embodiment 7:
The difference of the present embodiment and embodiment 1 is, does not carry DSI information on the E-DPCCH, and amount of information can be different under single current and the double-stream mode.The DSI information exchange is crossed other approach and is informed NodeB, such as sending by up Dedicated Control Channel DPCCH.PCI both can send by other approach, also can send at E-DPCCH.Table 20 is carried on E-DPCCH as example take PCI, provides the information of carrying on the E-DPCCH under the present embodiment Uplink MIMO pattern.

The amount of information that represents E-TFCI with m and n bit can be not limited to 7 bits, and the present embodiment describes as an example of m=n=7 example, in the practical application other values can also be arranged.Fig. 8 a is the coding flow chart in the control information transmission method shown in the present embodiment.Shown in Fig. 8 a:
In the present embodiment, the input and output of Multiplexing module are under the single-stream mode:

k＝x
h，1 k＝3；
y
k＝x
rsn1，6-k k＝4，5；

Take m=n=7 as example, the Multiplexing module input and output are under the double-stream mode:
y

Because single current is different with amount of information under the double-stream mode, therefore need accordingly the different channel coding method of use;
For single-stream mode, chnnel coding can be used linear block codes, encodes as follows:
M wherein
I, nCan be determined by (30,12) the linear block codes encoder matrix shown in the table 21, this form is the part of form 6, only uses M in the form 6 that is:
