It can be seen that the codebook is made up of two parts; wherein the content of the first and second substances,

so that the manner in which the features and technical contents of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the present invention will be rendered by reference to the appended drawings, which are included for purposes of illustration and not limitation.
In the process of implementing the codebook processing method, the inventor finds that the problem that the user equipment fails to report data to the network equipment is that the network equipment can obtain all channel information after receiving successfully once because the user equipment reports all channel information to the network equipment once; however, when the ue fails to report all the channel information, the network device cannot obtain any channel information. Based on this, the inventor proposes a technical scheme of the embodiment of the invention.
As shown in fig. 1, a first optional processing flow of the codebook processing method applied to the network device provided in the embodiment of the present invention includes the following steps:
step S101, the network device sends a first request message.
In an embodiment, a network device sends a first request message to a UE, where the first request message is used to request the UE to report part of channel information in all channel information;
in the embodiment of the invention, the network equipment requests the UE to report all channel information to the network equipment for multiple times, and only part of the channel information in all the channel information is reported each time. The part of channel information reported by the UE for many times can correspond to the same layer or different layers; thus, not only the rank1/2 transmission mode but also the rank3/4 transmission mode or a higher multi-stream transmission mode can be supported. When the UE reports partial channel information, different precisions can be adopted for different layers; in this way, a balance of network overhead and network performance is achieved.
Step S102, the network equipment receives the part of channel information reported by the UE.
In one embodiment, the partial channel information includes: a beam matrix index, a linear combining matrix, a first Channel Quality Indication (CQI); the first CQI is a CQI of partial channel information received by the network device this time, that is, a CQI corresponding to the beam matrix index and the linear combining matrix. The partial channel information is used for the network device to determine a precoding matrix constituting the codebook.
In an embodiment, when the network device receives, for the first time, the partial Channel information reported by the UE, the partial Channel information further includes a Rank Indication (RI) for indicating an effective number of data layers of a Physical Downlink Shared Channel (PDSCH). When the network device does not receive the partial channel information reported by the UE for the first time, the partial channel information may or may not include an RI; the RI has any one of values of 1, 2, 3, 4, 5, 6, 7 and 8.
In an embodiment, the network device sends the first request message through Downlink Control Information (DCI).
A second optional processing flow of the codebook processing method applied to the network device provided in the embodiment of the present invention is similar to the first optional processing flow of the codebook processing method applied to the network device, and the difference is that after step S102, the method further includes the steps of:
step S103, the network device determines a precoding matrix based on the received partial channel information, and a second CQI.
In this embodiment of the present invention, the second CQI is a CQI corresponding to the precoding matrix.
In an embodiment, each time the network device receives partial channel information corresponding to data of the same layer, calculating the product of a beam matrix corresponding to each received beam matrix index and a linear combination matrix; and determining the sum of the obtained products as the precoding matrix.
For example, the network device receives partial channel information reported by the UE for 4 times, and the partial channel information reported by the UE each time corresponds to layer 1, layer 2, and layer 3 data; the network device calculates the product of the beam matrix corresponding to the beam matrix index reported by the UE and the linear combination matrix reported by the UE each time, and determines the sum of the obtained products as the precoding matrix.
In another embodiment, when the partial channel information received by the network device each time corresponds to data of a different layer, the product of the beam matrix corresponding to the beam matrix index received each time and the linear combining matrix is calculated, and the product of the beam matrix calculated by the different layer and the linear combining matrix is concatenated to form the precoding matrix.
For example, the network device receives partial channel information reported by the UE for 4 times; and part of channel information reported by the UE each time corresponds to different layer data; the network device calculates the product of the beam matrix corresponding to the beam matrix index reported by the UE each time and the linear combining matrix, concatenates the calculated product of the beam matrix corresponding to the beam matrix index of each layer reported by the UE and the linear combining matrix, and determines the matrix obtained by the concatenation as the precoding matrix. In the embodiment of the invention, the partial channel information reported by the UE each time corresponds to different layer data, and the partial channel information reported each time can be understood as corresponding to the layer data which are not completely the same; if the partial channel information reported by the UE at the 1 st time corresponds to the data of the layer 1 and the layer 2, and the partial channel information reported by the UE at the 2 nd time corresponds to the data of the layer 2 and the layer 3; it can also be understood that the partial channel information reported each time corresponds to completely different layer data, for example, the partial channel information reported by the UE at 1 st time corresponds to the layer 1 data, the partial channel information reported by the UE at 2 nd time corresponds to the layer 2 data, and the partial channel information reported by the UE at 3 rd time corresponds to the layer 3 data.
When part of channel information reported by the UE each time corresponds to different layer data, determining the precoding matrix at least comprises the following two modes: in a first manner, if the UE reports the partial channel information of the layer 1 for the 1 st time, reports the partial channel information of the layer 2 for the 2 nd time, reports the partial channel information of the layer 3 for the 3 rd time, and reports the partial channel information of the layer 4 for the 4 th time, the product of the beam matrix corresponding to the beam matrix index of the layer 1 and the linear combining matrix, the product of the beam matrix corresponding to the beam matrix index of the layer 2 and the linear combining matrix, the product of the beam matrix corresponding to the beam matrix index of the layer 3 and the linear combining matrix, and the product of the beam matrix corresponding to the beam matrix index of the layer 4 and the linear combining matrix are concatenated, and the matrix obtained by the concatenation is determined to be the precoding matrix. In the second mode, if the UE reports the partial channel information of the layer 1 and the layer 2 for the 1 st time, the UE reports the partial channel information of the layer 2 and the layer 3 for the 2 nd time; firstly, respectively calculating the product of a beam matrix corresponding to a beam matrix index of a layer 1 and a linear combination matrix, the product of a beam matrix corresponding to a beam matrix index of a layer 3 and a linear combination matrix, the product of a beam matrix corresponding to a beam matrix index of a layer 2 reported at the 1 st time and a linear combination matrix, and the product of a beam matrix corresponding to a beam matrix index of a layer 2 reported at the 2 nd time and a linear combination matrix; secondly, calculating (for example merging) the product of the beam matrix corresponding to the beam matrix index of the layer 2 reported at the 1 st time and the product of the beam matrix corresponding to the beam matrix index of the layer 2 reported at the 2 nd time and the linear merging matrix to obtain the product of the beam matrix corresponding to the beam matrix index of the layer 2 after calculation and the linear merging matrix; and finally, cascading the product of the beam matrix corresponding to the beam matrix index of the layer 1 and the linear combination matrix, the product of the beam matrix corresponding to the beam matrix index of the layer 3 and the linear combination matrix, and the product of the beam matrix corresponding to the beam matrix index of the layer 2 and the linear combination matrix after operation, and determining the matrix obtained by cascading as the precoding matrix.
In an embodiment, the network device calculates the second CQI based on the beam matrix corresponding to the beam matrix index, the linear combining matrix, and the first CQI. An alternative embodiment for calculating the second CQI is: the network equipment receives the precoding matrix W1 and CQI1 reported by the UE for the first time, and the network equipment receives the precoding matrix W2 and CQI2 reported by the UE for the second time; wherein, the CQI1 is a first CQI received for the first time, and the CQI2 is a first CQI received for the second time;

where H is the channel response matrix, σ2Is the noise variance.
Figure PCTCN2018089835-APPB-000007
When W1 and W2 belong to the same channel eigenvector projection on two orthogonal beams, the following formula is obtained by performing power normalization:
Figure PCTCN2018089835-APPB-000008
another alternative embodiment for calculating the second CQI is: when the reported channel information corresponds to the projection of different layers on the beam matrix, the network equipment receives the precoding matrix W1 and CQI1 reported by the UE for the first time, and receives the precoding matrix W2 and CQI2 reported by the UE for the second time; wherein, the CQI1 is a first CQI received for the first time, and the CQI2 is a first CQI received for the second time;

W＝[W1W2](5)
because the channel information received by the network device at each time corresponds to different layers and the typeII quantization granularity is small, when L is large, it can be considered that there is no inter-stream interference, and the layers are combined by using ESM, resulting in the following formula:
CQI＝ESM(CQI1,CQI2) (6)
the third optional processing flow of the codebook processing method applied to the network device provided by the embodiment of the present invention is similar to the first optional processing flow of the codebook processing method applied to the network device, and the difference is that before the step S101, the following steps are further included:
step S301, the network device and the UE agree on reporting parameters.
Here, the reporting parameters at least include: the maximum reporting times N of the channel information and the layers corresponding to each reporting of the RI.
Step S302, the network equipment sends the beam selection information of the UE through the wireless resource control.
Here, the beam selection information is used for the UE to report the partial channel information to a network device; the beam selection information includes: the column number L of the beam matrix reported by the UE each timei(ii) a The column number of the beam matrix reported each time can be the same, namely the column number of the beam matrix reported each time is a constant; the number of columns of the beam matrix reported each time may also be different.
An optional processing flow of the codebook processing method applied to the network device, which is provided by the embodiment of the present invention, is similar to the optional processing flow of the codebook processing method applied to the network device, which is different in that after step S102, the method further includes the following steps:
step S104, when the network equipment fails to receive the partial channel information reported by the UE, the network equipment sends a second request message to request the UE to report the partial channel information repeatedly.
In an embodiment, the failure of the partial channel information reported by the UE refers to failure or loss of the UE receiving information sent by the network device through DCI, or failure of the network device receiving the partial channel information reported by the UE.
Here, the UE repeatedly reporting the partial channel information refers to reporting the partial channel information that the network device fails to receive by the UE.
In the above embodiments of the present invention, the codebook formed by the set of precoding matrices is an independent code, and the structure of each layer of the codebook is the same, and the structure of each layer is:
Wi＝W1,iW2,i；
wherein, WiIs the reporting of the precoding matrix for the ith time,from W1,iAnd W2,iThe product of (c).

The above embodiments of the present invention may be respectively used as an independent embodiment, or may be combined with each other; any technical solution that conforms to the logic of the codebook processing method obtained based on the mutual combination of the above embodiments of the present invention is within the scope of the present invention.
As shown in fig. 2, the optional processing flow one of the codebook processing methods applied to the UE provided in the embodiment of the present invention includes the following steps:
in step S501, the UE receives a first request message.
In the embodiment of the invention, UE receives a first request message sent by network equipment, wherein the first request message is used for requesting the UE to report part of channel messages in all channel messages to the network equipment.
In an embodiment, the first request message is sent by the network device to the UE through DCI.
Step S502, the UE reports partial channel information based on the first request message.
In the embodiment of the present invention, the partial channel information is used by the network device to determine a precoding matrix constituting the codebook; the partial channel information includes: a beam matrix index, a linear combining matrix, and a first CQI. The first CQI is a CQI corresponding to part of channel information reported by the UE this time, and may be understood as a CQI corresponding to a beam matrix index and a linear combining matrix.
In an embodiment, when the UE receives a first request message sent by the network device through DCI and requests the UE to report partial channel information for the first time, the UE calculates an RI based on a channel signal-to-noise ratio and a channel response matrix.
When the RI is calculated, the eigenvalue of H may be calculated first, then the channel capacity corresponding to each layer number is calculated, and the layer number with the largest channel capacity is searched as the current RI report.
In the embodiment of the present invention, the RI value is any one of 1, 2, 3, 4, 5, 6, 7, or 8.
In an embodiment, the UE receives a message from N1N2Selecting beam vectors with preset column numbers from the vectors; n is a radical of1And N2Respectively representing the port numbers of the network equipment antenna array in the horizontal direction and the vertical direction; and reporting a beam matrix index corresponding to a beam matrix formed by the beam vectors of the preset column number.
In practical implementation, the UE first selects L from N1N2 orthogonal 2D-DFT vectors according to one field indication in DCIiColumn beam vector of LiAnd the column beam vectors form a beam matrix, and a beam matrix index corresponding to the beam matrix is reported to the network equipment. Wherein, for quasi-periodic reporting, the L selected by the UEiThe column beam vector is a beam vector with a preset column number different from the reported beam matrix in the current period; for aperiodic reporting, the L selected by the UEiThe column beam vector is a beam vector of a predetermined number of columns different from the beam matrix that has been successfully reported in the current period.
And the UE calculates a linear combination matrix according to the channel response matrix and the beam matrix corresponding to the reported beam matrix index, and reports the calculated linear combination matrix to the network equipment.
And finally, calculating the CQI reported at this time according to the beam matrix corresponding to the beam matrix index reported currently and the linear combination matrix.
For example, the beam matrix W is known1,iCalculating a linear combination matrix W according to the channel response matrix H and the channel characteristic vector V corresponding to the channel response matrix2,i

Is the kth eigenvalue of channel H and N is the number of columns (i.e., layers) of eigenvector V.
For quasi-periodic reporting, after the UE finishes N times of reporting, entering the reporting period of the next partial channel information.
A second optional processing flow of the codebook processing method applied to the UE provided in the embodiment of the present invention is similar to the first optional processing flow of the codebook processing method applied to the UE, and the difference is that before step S501, the following steps are further included:
step S500, the UE and the network equipment agree on reporting parameters.
Here, the reporting parameter is at least the maximum number of reporting of the channel information and the layer of each reporting of the corresponding RI.
A third optional processing flow of the codebook processing method applied to the UE provided in the embodiment of the present invention is similar to the second optional processing flow of the codebook processing method applied to the UE, and the difference is that after step S502, the following steps are further included:
step S503, when the part of the channel information reported by the UE fails, receiving a second request message.
Here, the second request message is sent by the network device, and is used to request the UE to repeatedly report a partial channel message to the network device; the repeatedly reported partial channel information is reported lost partial channel information or reported wrong partial channel information.
Accordingly, after receiving the second request message, the UE may repeatedly report the partial channel information, or may not report the partial channel information.
As shown in fig. 3, the optional processing flow of the codebook processing method applied to the UE and the network device according to the embodiment of the present invention includes the following steps:
step S801, the UE and the network device agree on a reporting parameter.
In step S802, the network device transmits beam selection information of the UE through RRC.
Step S803, the network device sends a first request message to the UE, requesting the UE to report a part of channel messages in all channel messages to the network device.
Step S804, the UE reports partial channel information based on the first request message.
Step S805, the network device determines a precoding matrix and a corresponding channel quality indicator based on the received partial channel information.
Step S806, when the UE fails to report the partial channel information, the network device sends a second request message to the UE to request the UE to report the partial channel information to the network device repeatedly.
Step S807, the UE repeatedly reports partial channel information.
In the above embodiments of the present invention, part of the channel information reported by the UE to the network device may be divided into quasi-periodic reporting and aperiodic reporting; the following briefly outlines the procedure for periodically reporting the partial channel information by the UE and the procedure for quasi-periodically reporting the partial channel information by the UE.
Fig. 4 shows a schematic flow chart of aperiodic reporting of partial channel information by UE, where a network device is a base station, and the base station indicates, through DCI, that UE initially reports, and the UE reports RI and W1,1W1,2And a corresponding CQI1, the base station obtains partial channel information W ═ W1,1W1,2. The base station indicates the UE to report for the second time through DCI, and the UE reports W2,1W2,2And a corresponding CQI2, the base station obtains partial channel information W ═ W1,1W1,2+W2,1W2,2By analogy, the base station indicates UE to report for the m-th time through DCI, and the UE reports Wm,1Wm,2And a corresponding CQIm, the base station obtaining partial channel information W ═ W1,1W1,2+W2,1W2,2+...+Wm,1Wm,2。
Fig. 5 shows a schematic flow chart of quasi-periodically reporting partial channel information by UE, in which, taking network equipment as a base station as an example, the base station indicates the UE to report through DCI only once, and the UE reports RI, W1,1W1,2And corresponding CQI 1; reporting W by UE at a preset time interval from the first reporting of UE2,1W2,2And corresponding CQI2, and so on, UE reports Wm,1Wm,2And a corresponding CQIm.
The codebook processing method provided by the embodiment of the invention is explained based on different RRC configurations.
Can be optionally configured to
Adopting aperiodic report, presetting the reporting times N of UE to be 4, configuring a beam matrix adopted by the UE for each report by RRC to comprise 1 column of beam vectors, namely L1＝L2＝L3＝L4The layer number configuration corresponding to rank3 and rank4 is 1, as shown in table 1:
Figure PCTCN2018089835-APPB-000016
TABLE 1
The processing flow of the codebook processing method based on the first optional configuration in the embodiment of the present invention, as shown in fig. 6, includes the following steps:
step S901, a base station requests UE to report partial channel information through DCI; wherein, the DCI field of 0 indicates that the UE needs to report the RI. The beam matrix sequence number reported for the first time is used as a beam matrix index and a linear combination matrix, and a corresponding CQI 1. And the UE receives the DCI field of 0, calculates the current time Rank to be 4, selects an orthogonal matrix of N1N2 and reports the matrix index.
