End and base station.
Background technology
In wireless communication system, transmitting terminal and receiving terminal generally can obtain higher using adopting more antennas and sending and receiving
Rate.One principle of multi-antenna technology is that the multilayer transmission of match channels feature is formed using some features of channel,
The radiation direction of signal is very targeted, can effective lifting system performance, on the basis of not increasing bandwidth and power
It is a very promising technology, the extensive use in current system with regard to obtaining significant performance boost.Multiaerial system
Data transmission performance quality depend primarily on measurement and the feedback of channel information.Therefore the measurement of channel information and feedback are more
The core content of antenna technology;How to ensure that the accuracy of channel measurement and feedback of channel information, expense, robustness become one
A major issue.

(Channel State Information Reference Signal are referred to as channel state information reference signals
CSI-RS the measurement of descending channel information) can be used for.It is two classes that CSI-RS, which is divided to,:Non-precoded pilot tone (Non-Precede
CSI-RS, referred to as NP CSI-RS), precoded pilot (Beam Formed CSI-RS, referred to as BFed CSI-RS).For
NP CSI-RS, base station by all of the port send pilot tone, user receive pilot tone and measure, the method for feedback channel information obtains
It wins the confidence channel state information.For BFed CSI-RS, base station is different port group allocating pre-coding matrix, and will cover CSI-RS in K
CSI-RS loads are sent into (K >=1) on pre-coding matrix in resource, user measures equivalent channel and feeds back best CSI-RS
CSI in resource.

Change, and by uplink control channel (Physical Uplink Control Channel, referred to as PUCCH) to the CSI of quantization
Information (Channel quality indication, referred to as CQI;Rank Indicator, referred to as RI;Preceding
Matrix Indicator, referred to as PMI) periodically fed back.It base station can also be acyclic unexpected when needed
Triggering terminal carries out reporting for CSI information (including RI/PMI/CQI).To overcome periodic feedback real-time not high enough, CSI quantizations
Precision is limited to the problem of control channel expense.In addition, when terminal calculates feedback CSI, to be matched based on the semi-static of transmission mode
It sets, CSI calculating and feedback is carried out according to the hypothesis of transmission mode.
Two kinds of feedback classifications of CSI:
There are two types of the measurements of channel information and the classification of feedback:Respectively Class A and Class B.Two categories utilize
RRC signaling is semi-statically configured.
Class A:Base station send CSI-RS, generally non-precoded pilot tone, user be based on the CSI-RS pilot tones directly into
Row channel measurement and CSI quantizations, obtain RI/PMI/CQI.These contents are fed back on PUCCH or PUSCH, in feedback
Hold more, includes the beam direction in broadband.
Class B:The CSI-RS that base station is sent, generally precoded pilot, user may need first to carry out precoding to lead
The selection of frequency, then the quantization of the CSI-RS pilot tones progress channel information based on selection is fed back again, including CSI-RS resource
Index (CRI) selects information, and the CSI-RS of selection to measure the corresponding RI/PMI/CQI information of subset of resources.
In the related art, CSI is calculated and feedback needs to be semi-statically configured according to RRC signaling, and this mode is very big
Ground limits the flexibility that CSI feedback and transmission mode are chosen, and base station neatly dynamically cannot be transmitted mode according to CSI
Adjustment, to information transmission performance boost have larger limitation.For the above problem in the related technology, not yet exist at present
Effective solution scheme.

A mode describes the configuration of CSR parameters.
Mode one:The bit diagram configured in RRC signaling is the bit diagram of entire code book
For example antenna configuration is N1 rows N2 row, code book the first dimension oversample factor of configuration is O1, and the second dimension, which is crossed, adopts
Like factor is O2, then a total of Nb=N1*N2*O1*O2 beam of the first pre-coding matrix W1, arranges these beam
Row, each beam indicate that the beam that cannot be selected for terminal when bit indicates 0 indicates that terminal can when being 1 with a bit
With the beam of selection.This just makes the bit of W1 code books scheme each to indicate whether the beam in Nb beam can be with Nb bit

Purpose, for example, higher progress is needed on direction 1, then the corresponding bit of all beam all values near direction 1 are
1, otherwise, it is 1 that the bit value of one of beam can be only selected in several beam near this direction.
Under two layers of signal deployment mode, base station only needs the RRC signaling used in instruction terminal directly in DCI to configure
CSR bit set of graphs in that element index.

CSR bit diagrams N, wherein Nb1, Nb2 ..., NbN can be different value, i.e., the bit number that every sub- CSR bit diagram includes
Difference is but it is also possible to be identical.
It can there are many methods that sub- CSR bits are selected from total CSR bit diagrams, each method, and different work(may be implemented
Energy
Method 1:Realize that different sub- CSR set instructions have the purpose of code book of different oversample factors
The different purpose of this oversample factor that different directions may be implemented, the corresponding code word of total bit diagram are 8 times of mistakes
Sampling, as soon as sub- CSR bit diagrams 1 take the sub- CSR bit diagrams that a value is constituted from total CSR bit diagrams every 8 bit, then
The purpose of 1 times of over-sampling is realized, sub- CSR bit diagrams 2 take the son that a value is constituted from total CSR bit diagrams every 4 bit
CSR bit diagrams, then being achieved that the purpose of 2 times of over-samplings, sub- CSR bit diagrams 3 are from total CSR bit diagrams every 2 bit
The sub- CSR bit diagrams for taking a value to constitute, then being achieved that the purpose of 4 times of over-samplings.The selection of this seed CSR bit diagrams can
With the first pre-coding matrix W1 for 1 dimension code book, oversample factor O1 is at this moment only limited, the of 2 dimension code books can also be directed to
One pre-coding matrix W1, at this moment oversample factor includes the first dimension oversample factor O1 and the first dimension oversample factor O2,
Sub- CSR bit diagrams can reach the mesh of limitation O1 and O2 by selecting different sub- CSR bit diagrams in total CSR bit diagrams
's.
Method 2:Continuously take Nk bits as sub- CSR bit diagrams
Total bit diagram can be divided into Nb/Nk deciles, each decile includes the sub- CSR bit diagrams of continuous Nkbit sizes.
For example, Nk=8, then total bit diagram is divided into 8 deciles, each decile includes the sub- CSR bit diagrams of 8 bits.
Match CSR parameter sets in RRC, each CSR parameter sets include the sub- CSR bit diagrams for including Nk bits.
Under two layers of signal deployment mode, base station only needs the RRC signaling used in instruction terminal directly in DCI to configure
CSR bit set of graphs in that element index.
Terminal receives the CSR bit set of graphs of RRC configurations, and receives the CSR bit diagram index of set in DCI signalings, profit
The one's own CSR bit diagrams of base station configuration are found in the CSR bit sets that RRC is configured with CSR bit diagrams index of set
Value, so as to know which beam is limited.
And terminal can be according to the channel state information of itself, to the sub- CSR bit diagrams in the CSR set of DCI instructions
It is extended or reconstructs or assignment again, form new sub- CSR bit diagrams.Beam/ code words are carried out using new sub- CSR bit diagrams
Selection.Terminal can also feed back new sub- CSR bit diagrams.
In the case of three layers of signaling, base station in the mac layer, needs further to configure CSR subset of parameters by MAC CE,
It wherein include the index of the element in the bit set of graphs that one or more RRC is configured in CSR subset of parameters.And in DCI
The index of element in the CSR subsets configured in middle selection MAC layer.
Terminal receives the CSR bit set of graphs of RRC configurations, and receives the CSR subset of parameters of MAC CE configurations, and receives
Sub- CSR parameter sets index in DCI signalings, the sub- CSR parameter sets configured in MAC CE using sub- CSR parameter sets index

Similarly, and terminal can be according to the channel state information of itself, to the sub- CSR in the CSR set of DCI instructions
Bit diagram is extended or reconstructs or assignment again, forms new sub- CSR bit diagrams.It is carried out using new sub- CSR bit diagrams
The selection of beam/ code words.Terminal can also feed back new sub- CSR bit diagrams.
Here CSR bit diagrams or sub- CSR bit diagrams is exactly the element in CSR parameter sets, and CSR subset of parameters tables
Show the subclass of CSR parameter sets, is either directed toward the index of CSR parameter sets or the set of index.
In addition, terminal and base station can limit according to CSR and achieve the purpose that reduce feedback code expense.I.e. such as first is pre-
The expense of encoder matrix index i1 and/or the second precoding just index the expense of i2 very much.The wherein size of expense and following ginseng
Number is related:
CSR parameter sets indicate information,
CSR subset of parameters indicates information,
CSR parameters indicate information.
In the version 13 of LTE, the DFT vectors of the code book of design due to including two dimensions, number of codewords generally compares
More, this can increase the expense of feedback, in order to reduce expense, by code book according to codebook subset option and installment signaling (Codebook
Config) it is divided into different subclass, the corresponding different code word of different codebook subset configuration signals (CodebookConfig).Its
In under the same i11 and i12, when CodebookConfig=1, i2 code books only have 4 codes of co-phase Selecting phasings
Word, and CodebookConfig>When 1, i2 includes 16 code words such as co-phase Selecting phasings and beam selections.Wherein, i11 and
I12 corresponds to the first dimension index and the second dimension index of the first pre-coding matrix respectively.I2 corresponds to the second pre-coding matrix rope
Draw.
But this needs the value of RRC signaling configuration CodebookConfig, here can be by constructing in CSR parameter sets
The content of CSR bit diagrams, to achieve the purpose that carry out code book type selection to code book.Such as the CSR ratios in CSR parameter sets
Spy figure i limitation terminal can the identical i=1,2,3,4 of code word code word corresponding with CodebookConfig=i.To logical
It crosses configuration CSR parameter sets to achieve the purpose that limit i2 feedback overheads, such as in CSR bit diagrams 1, it is only necessary to feed back 2bit's
Cophasing, and when i=2,3,4, need the i2 for feeding back 4bit.
