Embodiment eight

This gives the specific implementation modes of feedback of channel information parameter configuration in embodiment seven.Mainly code book Subset limits the design of the more details of CSR and its feedback overhead.As shown in Fig. 5 (a), in the multiple bit diagrams of RRC configurations, and One or more of which bit diagram is selected in MAC CE or DCI signalings.Below by according to the form of bit diagram, it is divided into two 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 It is used.It is of course also possible to have the bit diagram of the second dimension pre-coding matrix W2 and the bit figures of other code books, it is provided to Limiting which code book can use, which code book terminal cannot use, and specific concept can refer to the association of LTE/LTE A View.

In the mode one of the present embodiment, bit diagram is all to include the bit diagram of entire code book, such as above-mentioned W1, needs Nb Bit indicates bit diagram.

RRC configures CSR parameter sets, and each element in set is the bit diagram of an entire code book, such as Fig. 5 (b) institutes Show, for example, respectively entire code book bit diagram 1, the bit diagram 2 of entire code book, the bit diagram 3 ... of entire code book, entire code This bit diagram N.

The value of bit is different in different bit diagrams, and the code word precision that can reach in different angle range is different 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.

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.

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 The value of the one's own sub- CSR parameter sets of base station configuration is found in index, and is existed according to the value of sub- CSR parameter sets The value of the acquisition CSR bit diagrams of RRC configurations, so as to know which beam is limited.

Mode two：The CSR bit diagrams of the 1 entire code book configured in RRC signaling, and configure and N number of be derived from total bit diagram CSR bit diagrams

As shown in Fig. 5 (c), RRC configures the total bit diagrams of CSR of an entire code book, and configures and N number of be taken from total bit diagram Sub- CSR bit diagrams：Such as the sub- CSR bit diagrams 1 of Nb1 bits, the sub- CSR bit diagrams 2 of Nb2 bits ..., the son of NbN bits 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.

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.

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 The value of the one's own sub- CSR parameter sets of base station configuration is found in index, and is existed according to the value of sub- CSR parameter sets The value of the sub- CSR bit diagrams of acquisition of RRC configurations, so as to know which beam is limited.

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.
