1. A method for transmitting feedback information, the method comprising:

a User Equipment (UE) performing time domain extension for feedback information within one subframe; and

mapping data which go through the time domain extension and demodulation reference signals corresponding to the data which

go through the time domain extension respectively to multiple uplink Single Carrier-Frequency Division Multiple Access (SC-FDMA)

symbols within the subframe, and transmitting the data which go through the time domain extension and the demodulation reference

signals corresponding to the data which go through the time domain extension in a same frequency domain position in a way

of time division multiplexing;

wherein each uplink SC-FDMA symbol occupies n successive physical resource blocks in a frequency domain, and n is a positive

integer;

wherein the step of performing time domain extension for feedback information comprises firstly dividing O bits of feedback

information into Y groups, and then encoding each group of data respectively;

wherein the step of dividing O bits of feedback information into Y groups comprises: starting from a first bit in a sequence

composed of feedback information, performing division into Y groups in order, except the last group,

bits contained in each group, and the number of bits contained in the last group being equal to or greater than

bits; or performing modulo operation between a location in which each bit is located in the sequence composed of the feedback

information and the Y, and classifying bits with identical modulo values under a group; or, when the feedback information

is channel state information, classifying bits representing feedback information corresponding to each cell under a group

correspondingly; or, starting from the first bit in the sequence composed of the feedback information, performing division

into Y groups in order, wherein the number of bits contained in each group of O mod Y groups is

and the number of bits contained in each group of remaining Y?(O mod Y) groups is

O is a positive integer, Y is a positive integer.
