[0023] The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0024] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0025] In wireless communication between two communication nodes, the first communication node transmits a signal to the second communication node, the second communication node feeds back channel state information to the first communication node, and the first communication node determines a transmission scheme based on the received channel state information, thereby improving the transmission efficiency. Figure 1 As shown: For example, a base station transmits a signal to a terminal, and the terminal feeds back channel state information to the base station. For another example, a first base station transmits a signal to a second base station, and the second base station feeds back channel state information to the first base station. For another example, a first terminal transmits a signal to a second terminal, and the second terminal feeds back channel state information to the first terminal.

[0026] In wireless communication, the first communication node transmits multiple layers of signals to the second communication node in a space division multiplexing manner, which improves the efficiency of communication. The first communication node maps the signal to the antenna port through a precoding matrix for transmission, and transmits multiple layers of signals; in this way, each layer of the transmitted signal corresponds to each column vector in the precoding matrix. One special case is that the first communication node transmits a layer of signal to the second communication node. The first communication node determines the space division multiplexing transmission scheme based on the channel state information fed back by the second communication node. The channel state information fed back by the second communication node includes information about the precoding matrix.

[0027] Example 1

[0028] In this embodiment, a method for processing channel state information is provided. Figure 2 is a flow chart of a method for processing channel state information according to an embodiment of the present disclosure. Figure 2 As shown, the process includes the following steps:

[0029] Step S202, the second communication node receives configuration information sent by the first communication node; wherein the configuration information at least includes: a target frequency band for indicating channel state information;

[0030] Step S204: According to the configuration information, the second communication node determines a first target frequency band and generates first channel state information corresponding to the first target frequency band, wherein the first channel state information includes: precoding matrix information;

[0031] Step S206: The second communication node feeds back the first channel state information to the first communication node.

[0032] It should be pointed out that Figure 1 A wireless communication scenario applicable to the solution recorded in this implementation is described in the text; the first communication node includes one of the following: user equipment UE, network side device; the second communication node includes one of the following: the UE, the network side device. Of course, other nodes capable of wireless communication are also applicable to this implementation. I will not go into details here.

[0033] Specifically, according to the configuration information, the second communication node determines a second target frequency band and generates second channel state information corresponding to the second target frequency band; the channel state information is composed of the first channel state information and the second channel state information; the second communication node feeds back the second channel state information to the first communication node.

[0034] Specifically, the first target frequency band is the applicable frequency band of the precoding matrix information, that is, the precoding matrix information is fed back for these frequency bands. The second target frequency band is the applicable frequency band of other channel state information in the channel state information except the precoding matrix information, that is, other channel state information is fed back for these frequency bands. Other channel state information, for example, includes channel quality indication information, for example, includes channel strength information. The second communication node determines the first target frequency band to accurately determine the precoding matrix information on the target frequency band, so as to accurately feed back the precoding matrix information on the target frequency band. The second communication node determines the second target frequency band to accurately determine other channel state information in the channel state information except the precoding matrix information, so as to accurately feed back other channel state information on the corresponding target frequency band. The first communication node obtains the first target frequency band to accurately determine the frequency band to which the received precoding matrix information is applicable, so as to determine an appropriate precoding usage scheme. The first communication node obtains the second target frequency band to accurately determine the frequency band to which the other received channel state information is applicable, so as to determine an appropriate other channel state information usage scheme.

[0035] Specifically, the configuration information also includes: pre-set location information, and the second communication node determines the location of the first target frequency band and / or the second target frequency band according to the pre-set location information.

[0036] Specifically, the pre-set position information includes at least one of the following: pre-set starting position information, pre-set ending position information; the second communication node determines the position of the first target frequency band and / or the second target frequency band according to the pre-set position information, including: the second communication node determines the starting position of the first target frequency band or the starting position of the second target frequency band according to the pre-set starting position information, and / or the second communication node determines the ending position of the first target frequency band or the ending position of the second target frequency band according to the pre-set ending position information.

[0037] For example, the first target frequency band is equal to the second target frequency band. For another example, the first target frequency band includes a frequency band that is lower than the second target frequency band. For another example, the first target frequency band includes a frequency band that is higher than the second target frequency band.

Figure 4 A frequency domain diagram according to an embodiment of the present disclosure Figure 2 . Figure 5 A frequency domain diagram according to an embodiment of the present disclosure Figure 3 For ease of understanding, Figure 3-Figure 5In FIG. 1 , the first target frequency band and the second target frequency band are compared and represented by two frequency domain schematic diagrams in the same frequency domain range. Figure 3 As shown in FIG. 1 , the frequency domain units of the oblique line portion corresponding to the first target frequency band are {1, 2, 3, 4, 5, 6}, and the frequency domain units of the horizontal line portion corresponding to the second target frequency band are {1, 2, 3, 4, 5, 6}. Therefore, the first target frequency band is equal to the second target frequency band. Figure 4 As shown in FIG. 1 , the frequency domain units of the oblique line portion corresponding to the first target frequency band are {1, 2, 3, 4, 5, 6}, and the frequency domain units of the horizontal line portion corresponding to the second target frequency band are {4, 5, 6, 7, 8, 9}. Therefore, the first target frequency band includes a frequency band lower than the second target frequency band. Figure 5 As shown, the frequency domain unit of the oblique line portion corresponding to the first target frequency band is {4,5,6,7,8,9}, the frequency domain unit of the horizontal line portion corresponding to the second target frequency band is {1,2,3,4,5,6}, and the first target frequency band includes a frequency band higher than the second target frequency band. It should be noted that the first target frequency band can include both a frequency band lower than the second target frequency band and a frequency band higher than the second target frequency band, which will not be described in detail here.

[0039] In another embodiment, the first target frequency band is determined according to the second target frequency band. For example, the first target frequency band is equal to the second target frequency band.

[0040] The first target frequency band is determined according to the second target frequency band, and resource overhead indicating the first target frequency band can be saved. The channel state information includes precoding matrix information, and the first target frequency band (the target frequency band of the precoding matrix information) and the second target frequency band (the target frequency band of the channel state information other than the precoding matrix information) have a certain correlation, and the resource overhead indicating the first target frequency band can be saved by using the correlation between them.

[0041] For another example, the first target frequency band is composed of the second target frequency band and a frequency band lower than the starting position of the second target frequency band. For another example, the first target frequency band is composed of the second target frequency band and a frequency band higher than the ending position of the second target frequency band. For another example, the first target frequency band is composed of the second target frequency band, a frequency band lower than the starting position of the second target frequency band, and a frequency band higher than the ending position of the second target frequency band.

[0042] Combined with Figure 6 Let's give an example. Figure 6As shown, a continuous frequency domain is divided into 19 frequency domain units, marked as {0,1,2,...,18}; the set of frequency domain units marked with diagonal lines in the figure is the second target frequency band, that is, the frequency domain units {2,3,5,7,9,11}. The first target frequency band is equal to the second target frequency band, for example, the frequency domain units {2,3,5,7,9,11}. The first target frequency band consists of the second target frequency band and a frequency band lower than the starting position of the second target frequency band, for example, the frequency domain units {1,2,3,5,7,9,11}. The first target frequency band consists of the second target frequency band and a frequency band higher than the ending position of the second target frequency band, for example, the frequency domain units {2,3,5,7,9,11,12}. The first target frequency band is composed of the second target frequency band, a frequency band lower than the start position of the second target frequency band, and a frequency band higher than the end position of the second target frequency band, for example, frequency domain units {1, 2, 3, 5, 7, 9, 11, 12}.

[0043] In yet another embodiment, the first target frequency band is determined according to a frequency band spanned by the second target frequency band.

[0044] It should be noted that the frequency band spanned by the second target frequency band is a continuous frequency band, the starting position of which is the starting position of the second target frequency band, and the ending position of which is the ending position of the second target frequency band.

[0045] The first target frequency band is determined according to the frequency band spanned by the second target frequency band, and precoding matrix information of a frequency band including the second target frequency band and having a larger range can be provided, and the first target frequency band is closely related to the second target frequency band; that is, the first communication node can obtain more precoding matrix information about the second target frequency band, which is conducive to determining the transmission scheme.

[0046] For example, the first target frequency band is equal to the frequency band spanned by the second target frequency band. For another example, the first target frequency band is composed of the frequency band spanned by the second target frequency band and the frequency band lower than the starting position of the second target frequency band. For another example, the first target frequency band is composed of the frequency band spanned by the second target frequency band and the frequency band higher than the ending position of the second target frequency band. For another example, the first target frequency band is composed of the frequency band spanned by the second target frequency band, the frequency band lower than the starting position of the second target frequency band, and the frequency band higher than the ending position of the second target frequency band.

[0047] Combined with Figure 6 Let's give an example. Figure 6As shown, a continuous frequency domain is divided into 19 frequency domain units, marked as {0,1,2,...,18}; the set of frequency domain units marked with diagonal lines in the figure is the second target frequency band, that is, the frequency domain units {2,3,5,7,9,11}; the frequency band spanned by the second target frequency band is the frequency domain unit {2,3,4,5,6,7,8,9,10,11}. The first target frequency band is equal to the frequency band spanned by the second target frequency band, for example, the frequency domain unit {2,3,4,5,6,7,8,9,10,11}. The first target frequency band is composed of the frequency band spanned by the second target frequency band and the frequency band lower than the starting position of the second target frequency band, for example, the frequency domain unit {1,2,3,4,5,6,7,8,9,10,11}. The first target frequency band is composed of the frequency band spanned by the second target frequency band and the frequency band higher than the end position of the second target frequency band, for example, the frequency domain unit {2,3,4,5,6,7,8,9,10,11,12}. The first target frequency band is composed of the frequency band spanned by the second target frequency band, the frequency band lower than the start position of the second target frequency band, and the frequency band higher than the end position of the second target frequency band, for example, the frequency domain unit {1,2,3,4,5,6,7,8,9,10,11,12}.

[0048] In another embodiment, based on the configuration information, the second communication node determines the first target frequency band, for example, the non-continuity of the second target frequency band in the frequency domain indicates that the first target frequency band includes the frequency band spanned by the second target frequency band; for another example, the first target frequency band includes the frequency band spanned by the second target frequency band which is non-continuous in the frequency domain.

[0049] Specifically, when the second target frequency band is analyzed according to the configuration information to be non-continuous in the frequency domain, the second communication node determines that the first target frequency band includes the frequency band spanned by the second target frequency band. Alternatively, the second communication node determines that the first target frequency band includes the frequency band spanned by the second target frequency band that is non-continuous in the frequency domain.

[0050] Therefore, since the frequency bands spanned by the second target frequency band included in the first target frequency band are continuous, the channel coefficients are smoother in the continuous frequency domain, thus making the processing from the channel coefficients to the precoding matrix information simpler, thereby reducing the complexity.

[0051] Specifically, according to the configuration information, the second communication node determines the first target frequency band, including: the second communication node determines the first target frequency band based on the second target frequency band and a bandwidth block, wherein the bandwidth block is a continuous frequency band in the working carrier, including the second target frequency band.

[0052] In this way, the relationship between the complexity of obtaining the precoding matrix information to be fed back and the feedback overhead can be balanced.

[0053] Specifically, the second communication node determines the first target frequency band according to the second target frequency band and the bandwidth block, including: the second communication node determines the first target frequency band according to a first bandwidth ratio of the second target frequency band to the bandwidth block.

[0054] Specifically, the second communication node determines the first target frequency band according to the first bandwidth ratio of the second target frequency band to the bandwidth block, including: when the first bandwidth ratio is greater than or equal to the first preset ratio threshold, the second communication node determines the first target frequency band according to the frequency band spanned by the second target frequency band in the frequency domain. In this way, the complexity of obtaining the precoding matrix information to be fed back is reduced without increasing the feedback resource overhead. When the first bandwidth ratio is less than the first preset ratio threshold, the second communication node determines the first target frequency band according to the second target frequency band; this can reduce the feedback resource overhead. Or, the second communication node determines the first target frequency band according to the number of resources fed back.

[0055] Specifically, the second communication node determines the first target frequency band according to the bandwidth ratio of the second target frequency band to the bandwidth block, and also includes: the second communication node determines the first target frequency band according to a first ratio of the bandwidth of the second target frequency band to a first threshold value and a second ratio of the bandwidth of the bandwidth block to a second threshold value.

[0056] For example, Table 1 is a method for determining according to the first ratio and the second ratio, as shown in Table 1:

[0057] Table 1

[0058]

[0059] For example, Table 2 is another method for determining the first ratio and the second ratio, as shown in Table 2:

[0062]

[0063] Specifically, according to the configuration information, the second communication node determines the first target frequency band, including: the second communication node determines the first target frequency band according to the bandwidth of the second target frequency band and the bandwidth of a frequency band spanned by the second target frequency band.

[0064] In this way, the relationship between the complexity of obtaining the precoding matrix information to be fed back and the feedback overhead can be balanced.

[0065] Specifically, the second communication node determines the first target frequency band based on the bandwidth of the second target frequency band and the bandwidth of the frequency band spanned by the second target frequency band, including: the second communication node determines the first target frequency band based on a second bandwidth ratio of the bandwidth of the second target frequency band and the bandwidth of the frequency band spanned by the second target frequency band.

[0066] Specifically, the second communication node determines the first target frequency band according to a second bandwidth ratio of the bandwidth of the second target frequency band to the bandwidth of the frequency band spanned by the second target frequency band, including one of the following: 1) When the second bandwidth ratio is greater than or equal to a second preset ratio threshold, the second communication node determines the first target frequency band according to the frequency band spanned by the second target frequency band; in this way, the complexity of obtaining the precoding matrix information to be fed back is reduced without increasing the feedback resource overhead. 2) When the second bandwidth ratio is less than the second preset ratio threshold, the second communication node determines the first target frequency band according to the second target frequency band; in this way, the feedback resource overhead can be reduced. Or, the second communication node determines the first target frequency band according to the number of resources fed back.

[0067] Specifically, the second communication node determines the first target frequency band based on the second target frequency band and the frequency band spanned by the second target frequency band, including: the second communication node determines the first target frequency band based on a first size and a second size, wherein the first size is the size of a codebook vector determined according to the second target frequency band, and the second size is the size of a codebook vector determined according to the frequency band spanned by the second target frequency band.

[0068] Specifically, the second communication node determines the first target frequency band based on a first size and a second size, including: when the first size is greater than or equal to the first size, the second communication node determines that the first target frequency band is equal to the frequency band spanned by the second target frequency band; when the first size is smaller than the first size, the second communication node determines that the first target frequency band is equal to the second target frequency band.

[0069] Specifically, the second communication node generates the first channel state information corresponding to the first target frequency band, including: the second communication node determines the first target frequency band according to the indication information, wherein the indication information includes at least one of the following: first indication information, used to indicate the first target frequency band by bit mapping, wherein the size of the frequency domain unit corresponding to each bit is indicated by the network side node; second indication information, used to indicate the starting position and the frequency band bandwidth of the first target frequency band; third indication information, used to indicate the starting position and the ending position of the first target frequency band; fourth indication information, used to indicate the ending position and the frequency band bandwidth of the first target frequency band. Wherein, corresponding to the second indication information, the first target frequency band is a continuous frequency band starting from the starting position and having a frequency band bandwidth of the frequency band bandwidth; wherein, corresponding to the third indication information, the first target frequency band is a continuous frequency band starting from the starting position and ending at the ending position; wherein, corresponding to the fourth indication information, the first target frequency band is a continuous frequency band ending at the ending position and having a frequency band bandwidth of the frequency band bandwidth of the frequency band bandwidth.

[0070] Specifically, the configuration information further includes: determination indication information, before the second communication node determines the first target frequency band according to the configuration information, the method further includes: according to the determination indication information, the second communication node obtains a method for determining the first target frequency band, wherein the determination indication information includes one of the following: determining the first target frequency band according to the second target frequency band; determining the first target frequency band according to the frequency band spanned by the second target frequency band. In this way, the first communication node can balance complexity and overhead to achieve a comprehensive effect of the system.

[0071] Specifically, the configuration information also includes: frequency band information of the second target frequency band, wherein the frequency band information of the second target frequency band includes at least one of the following: the starting and ending positions and the frequency band bandwidth of the second target frequency band; the ending position and the frequency band width of the second target frequency band; the starting position and the ending position of the second target frequency band; and the continuity of the second target frequency band in the frequency domain.

[0072] Specifically, the frequency band information of the second target frequency band also includes: fifth indication information for indicating the second target frequency band in a bit mapping manner; and determining, according to the fifth indication information, that the frequency bands spanned by the first target frequency band and the second target frequency band are equal.

[0073] Specifically, the second communication node determines the first target frequency band, including: the second communication node determines that the first target frequency band is equal to the second target frequency band according to the frequency band information of the second target frequency band. For example, the first target frequency band is determined to be equal to the second target frequency band according to the following frequency band information of the second target frequency band, and the frequency band information includes one of the following: the starting and ending positions and the frequency band width of the second target frequency band; the ending position and the frequency band width of the second target frequency band; the starting position and the ending position of the second target frequency band; the continuity of the second target frequency band in the frequency domain.

[0074] In yet another embodiment, the second communication node determines the first target frequency band and the second target frequency band, including: the first target frequency band is determined according to the manner in which the second target frequency band is indicated.

[0075] For example, the second target frequency band is indicated by bit mapping, and the frequency bands spanned by the first target frequency band and the second target frequency band are determined to be equal.

[0076] The second target frequency band is indicated by one of the following methods to determine that the first target frequency band is equal to the second target frequency band:

[0080] In yet another embodiment, the second communication node determines the first target frequency band and the second target frequency band, including: the first target frequency band and the second target frequency band are equal, associated with the manner in which the second target frequency band is indicated.

[0081] For example, the first target frequency band is equal to the second target frequency band to determine the way in which the second target frequency band is indicated; for example, the way in which the second target frequency band is indicated determines that the first target frequency band is equal to the second target frequency band; for example, the first target frequency band is equal to the second target frequency band, and the way in which the second target frequency band is indicated exists at the same time. In this way, the overhead of the target frequency band indicating the channel state information can be used to indicate the second target frequency band and the second target frequency band at the same time, thereby achieving the effect of saving resource overhead.

[0082] For another example, the first target frequency band is equal to the second target frequency band, and is associated with the manner in which the second target frequency band is indicated, including: the manner in which the associated second target frequency band is indicated includes one of the following:
