The concept of some spatial informations of the present embodiment may be referred to the agreement of all kinds of versions in Long Term Evolution for example,
TS36.211, TS36.212, TS36.213, but it is also not limited to the middle effect of Long Term Evolution agreement or other agreements
Identical related notion or name.The related notion of wherein code book is described below：
The code book of LTE is with the evolution of Standard Edition, also in continuous evolution, in version (Release) 8 and Release
The code book of the code book of 4 antennas and 2 antennas is all the form of single codeword in 9, only a pre-coding matrix instruction (Precoding
Matrix Indication, PMI), its value is expressed as i=1 ..., N11, N11For the number of code word.At 8 days of Release 10
It is exactly the form of this feedback of dicode when 4 antenna codebook of line code sheet and Release 12, i.e. code word can be write as W=W1*W2
Form, and W1It is the code book of long-term feedback, is known as the first code book, generally there is N11A group, each group includes M1A alternative ripple
Beam, user select N11A group of a group index feeds back to base station, this feedback generally uses PMI1To quantify and feed back, its value one
As use i1=1 ..., N11Represent, N11For the W1Number；W2Represent the code book of a short-term feedback, be known as the second code book, it
Effect be in W1M is selected in code word1One in a alternative wave beam, and selected for each polarization direction of same data Layer
Beam selection polarization phases (Co-phasing), W2In each code word PMI2Quantify and feed back, its value is i2=1 ...,
M1, M1For W2Number, wherein the N under every kind of order (Rank)11And M1Value it is different, specifically may be referred to LTE Release
10 agreements.
(Dimension, D) aerial array is tieed up both for 1 in the pervious code words of R12, belongs to the code word of 1D,
In being designed in the code book of Release 13, due to the use of more antennas, the dimension of code book becomes much larger.The topology of antenna
Be typically also planar array, that is, the Antenna Design code word of 2D for having two dimension directions.So as to the first code book W1In it is every
A wave beam has the form that form 2 is tieed upWherein, vmAnd unThe respectively discrete fourier of the first dimension and the second dimension
Vector (Discrete Fourier Transform, DFT),Represent vmAnd unKronecker products, m=1,
2,…,B1, n=1,2 ..., B2.(in the present invention, port includes but not limited to antenna/port/ ports/transmission for first dimension port
Unit/a period of time/array element etc. can send the device of signal) number N1It is a, the second dimension port number N2A, the first dimension port corresponds to
DFT carried out O1Over-sampling again, the corresponding DFT in port of the second dimension have carried out O2Over-sampling again, above-mentioned first dimension
Or second dimension antenna discrete fourier vector number be port number oversample factor multiple, so there is B1=
N1*O1, B2=N2*O2, O1For the first dimension oversample factor, O2For the second dimension oversample factor.First dimension of the first code book
Spend code book PMI11Represent, its value is i11=1 ..., N11, the code book PMI of the second dimension of the first code book12Represent, its value is
i12=1 ..., N12.For each above-mentioned PMI11And PMI12Index, have M1A W2Code word, each W2Code word is exactly to be
From W1In selection 2 dimension wave beamsAnd the Co-phasing of different polarization directions, corresponding codewords indexes are PMI2, use
i2=1 ..., M1Represent.Due to PMI11, PMI12And PMI2The sum of bit number of feedback it is general bigger, feedback overhead is big,
User selects the complexity of code book high, and in order to solve this problem, normal structure is by by W2In M1A code word is divided into K kinds and matches somebody with somebody
Put, every kind of configuration includes M1A codebook subset in a code word closes, for example one of configuration set is as follows, i ' here2
That is PMI2In a specific index.As can be seen that each configuration is a subset conjunction in 32 code words.This is matched somebody with somebody
The order put generally has high-level signaling codebook subset configuration signal (Codebook Config) to be allocated to user, which includes 4
The possible value of kind, respectively configures (Configuration, Config) 1, Config2, Config3, Config4.
Without loss of generality, the first dimension port number N11=the 1 or second dimension port number N12=1 code word becomes 1D codes
Word, and the first dimension port number N11>The 1 and second dimension port number N12>1 code word becomes 2D code words.If 1D code words and being
Single codeword structure represents with PMI or i, if 1D code words and using PMI in double codeword structures1And PMI2It is common to represent, index
By i1/i2It is common to represent, if 2D code words PMI11, PMI12, PMI2Three code book indexes represent or by indexing i jointly11,
i12, i2It is common to represent.
It is required it is noted that the port in the invention of this reality can also be antenna, transmission unit, receiving unit, a period of time, etc.
