In embodiments of the present invention, pre-coding matrix using sequentially can be described as pre-coding matrix using sequence, prelist
Code sequence, precoding use sequence etc..
The embodiment of the present invention is to update granularity to update pre-coding matrix with m data, can preferably obtain channel and jump
The diversity gain of frequency narrowband improves demodulation performance；And transmitting terminal is used according to predefined pre-coding matrix using sequence pre-
Encoder matrix, using sequence, therefore when CRS demodulation, transmitting terminal is not needed to receiving end the pre-coding matrix known to receiving end
Notify precoding matrix information.
In the present embodiment, resource unit group also includes enhanced resource unit group (Enhanced REG, EREG)；Control letter
Road unit also includes enhanced control channel unit (Enhanced Control Channel Element, ECCE).
Optionally, ifThen first-time precoding is updated for the data of each EREG；IfIt is then each
The data of PRB update first-time precoding.M can be default configuration, can also pass through system information block (System by transmitting terminal
Information Block, SIB) notice receiving end；Wherein receiving end can be terminal etc..
Optionally, in the present embodiment, every m data uses same pre-coding matrix, and every m data update once prelists
Code matrix.Therefore, control channel can use multiple pre-coding matrixes in a transmission subframe, be that this multiple pre-coding matrix is pre-
One is first defined using sequence.It on the one hand, is to update granularity to update precoding with a certain number of data, it being capable of better diversity
The fading profiles of channel and frequency hopping narrowband improve demodulation performance.On the other hand, the control demodulated based on pre-coding matrix and CRS
Channel, receiving end need to learn that pre-coding matrix could be completed to demodulate, and transmitting terminal can not real-time informing control channel variation
Therefore pre-coding matrix pre-defines a precoding and uses sequentially, this known sequence of receiving end, then known precoding square

Channel subframes update first-time precoding sequence using same precoding sequence, every Y subframe.Because of the subframe integrated channel of CRS
Estimation does not need precoding configuration having the same between subframe, so, no matter control channel is to repeat transmission or non-duplicate biography
It is defeated, it can consider that each control channel subframe updates using sequentially for first-time precoding matrix.Optionally, the size of Y is silent
Recognize configuration, or receiving end is notified by system information block by transmitting terminal.In addition, all control channel subframes can also be with
Using same precoding sequence, Y is equal to the transmission number of sub frames of control channel at this time, does not need the relevant value explanation of Y.
In an alternate embodiment of the present invention where, the mode of update may include: that pre-coding matrix is used sequence

2 ..., P-1] cyclic shift, P be available precoding number, cyclic shift numerical value here can be positive integer, bear it is whole
Number and 0.Precoding is recycled according to the indexed sequential in control channel data.
For example, current pre-coding matrix index sequence is [0,1,2,3], and shares every 2 data of 16 data and update one
Secondary precoding, then the pre-coding matrix index that each data use be followed successively by [0,0,1,1,2,2,3,3,0,0,1,1,2,2,3,
3], i.e., every two data update first-time precoding, and precoding is recycled in sequence.
For another example, current pre-coding matrix index sequence is [1,2,3,0], and shares every 2 data of 16 data and update one
Secondary precoding, then the pre-coding matrix index that each data use be followed successively by [1,1,2,2,3,3,0,0,1,1,2,2,3,3,0,
0]。
In the present embodiment optionally, it is contemplated that pre-coding matrix uses the update of sequence, then has k-th of data to use pre-
Encoder matrix indexesWherein, j indicates that the use sequence jth time of precoding updates, and j is more than or equal to
0, s is cyclic shift value, as s=0, cyclic shift is not present, also all subframes of secondary indication control channel use same
Precoding sequence.
For example, it is assumed that initial pre-coding matrix index sequence is [0,1,2,3], the every m=2 data of 16 data are shared
Update first-time precoding, cyclic shift s=1, then, when j=0, that is, precoding does not update, precoding that the 5th data use
Matrix index is 2, and when j=1 is to update precoding for the first time, the pre-coding matrix index that the 5th data use is 3.
In the present embodiment optionally, predefined pre-coding matrix is default configuration using sequence；Or existed by transmitting terminal
