Description

[Technical Field]

[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims priority to a Chinese patent application with application number 202111143952.5 filed in China on September 28, 2021, the entire contents of which are incorporated herein by reference.

[0002] The present application belongs to the technical field of communications, and specifically relates to a combination number processing method, a sequence determination method, an apparatus, a device, and a storage medium. [Background technology]

[0003] In some communication systems (e.g., 5th-Generation (5G) or 6th-Generation (6G) systems), a terminal supports reducing signaling overhead by reporting the number of combinations. However, in current techniques for a terminal to report the number of combinations, the terminal always reports the number of combinations corresponding to the sequence selected by the terminal, which can increase the overhead of reporting the number of combinations. In addition, the complexity of the current method for calculating the number of combinations increases as the length of the selected sequence increases. Also, currently, the maximum value indicated in the column in the table for the terminal to calculate the number of combinations is too small, so the length of the sequence corresponding to the reported number of combinations is too short. It can be seen that the performance of a terminal's reporting the number of combinations is currently relatively poor. Summary of the Invention [Problem to be solved by the invention]

[0025] Hereinafter, the combination number processing method, sequence determination method, device, equipment, and storage medium provided in the embodiments of the present application will be described in detail with reference to the drawings according to several embodiments and their application scenarios.

[0026] Referring to FIG. 2, which is a flowchart of the combination number processing method provided in the embodiment of the present application, as shown in FIG. 2, it includes the following steps 201 and 202.

[0027] In step 201, the terminal selects a sequence.

[0028] The terminal selecting a sequence may mean that the terminal selects one or more elements from the entire sequence, for example, that the terminal selects all or some of the elements in the entire sequence.

[0029] All of the above sequences are defined by a protocol, set on the network side, or set in advance, such as an arithmetic progression from 0 to a certain length with a step size of 1.

[0030] In step 202, the terminal executes a target action based on a sequence selected by the terminal, the target action being: determining a target number of combinations and reporting said target number of combinations; If the sequence selected by the terminal is all of the total sequences, not reporting the number of combinations; The target number of combinations is In the first table for calculating the target number of combinations, the maximum value indicated in the column is greater than half of the maximum value indicated in the row; When the first condition is satisfied, the target number of combinations is calculated using a target calculation method, and in the target calculation method, the number of combinations of the first value and the second value for the third value is the same, and the sum of the first value and the second value is the third value; When the length of the sequence selected by the terminal is greater than half the sequence length of all sequences, the target combination number is the number of combinations corresponding to the reverse sequence, or when the length of the sequence selected by the terminal is greater than half the sequence length of all sequences, the target combination number is the number of combinations obtained by subtracting the number of combinations corresponding to the reverse sequence from the reference combination number, and the reverse sequence is a sequence consisting of all elements in all sequences other than the sequence selected by the terminal, or when the sequence selected by the terminal is the entirety of the all sequences, the reverse sequence is empty and the reference combination number is C(N,L)-1, where N is the sequence length of the all sequences, L is the length of the sequence selected by the terminal, and C(N,L) represents the number of combinations of N and L; When the length of the sequence selected by the terminal is equal to or less than half the sequence length of all the sequences, the target number of combinations is the number of combinations corresponding to the sequence selected by the terminal.

[0031] When the sequences selected by the terminal are all of the entire sequences, it means that the terminal selects all elements in all of the sequences. Therefore, in this case, even if the number of combinations is not reported, the network side device can know that the terminal has selected all elements in all of the sequences. This saves the terminal's reporting resources and improves the terminal's performance in reporting the number of combinations.

[0032] In addition, in the embodiment of the present application, when the sequence selected by the terminal is all of the total sequences, a target combination number may be determined and the target combination number may be reported. Specifically, the reverse sequence may be determined to be empty, which indicates that the sequence selected by the terminal is all of the total sequences, and the combination number corresponding to the target combination sequence being empty may be determined to be 0, and the combination number 0 may be reported; or the combination number calculation formula may be directly used to calculate that the combination number of the sequence selected by the terminal is 0, which indicates that the sequence selected by the terminal is all of the total sequences, and the combination number 0 may be reported.

[0033] In an embodiment of the present application, the sequence selected by the terminal may include one or more elements. That is, the length of the sequence selected by the terminal is an integer equal to or greater than 1. Each element can correspond to one C(x,y), and the number of combinations corresponding to the sequence selected by the terminal is the number of combinations calculated from C(x,y) corresponding to all elements in the sequence. For example, if the target number of combinations is the number of combinations corresponding to the sequence selected by the terminal, the target number of combinations can be calculated using the following formula:

[0034] [Number 1] JPEG0007733229000001.jpg1454

[0035] where i com represents the target number of combinations, and the above C(N-1-n (i) , Li) can be obtained by table lookup. Specifically, it can be obtained by referring to the first table, the second table provided in the embodiment of this application, or other tables defined in the protocol, and n (i) is an index corresponding to the i-th element in the sequence selected by the terminal, where i is the i-th element in the sequence selected by the terminal, and i=0, . . . , L-1.

[0036] It should be noted that in this disclosure, C(,) is the number of combinations, specifically, it can be expressed as C(x, y), that is, in the above formula, X is N-1-n (i) and y is a point in Li.

[0037] For example, if the target combination number is a combination number corresponding to the reverse sequence, the target combination number can be calculated by the following formula:

[0038] [Number 2] JPEG0007733229000002.jpg2191

[0039] where i com represents the target number of combinations, and the above C(N-1- m (i) , Li) can be obtained by table lookup. Specifically, it can be obtained by referring to the first table, the second table provided in the embodiment of this application, or other tables defined in the protocol, and m (i) is an index corresponding to the i-th element in the reverse sequence, where i represents the i-th element in the reverse sequence, and i=0,...,NL-1. N=L indicates that the sequence selected by the terminal is all of the total sequences. In this way, if the sequence selected by the terminal is all of the total sequences, no table lookup is required, and i com =0 was calculated directly.

[0040] It should be noted that in the embodiments of the present application, the embodiment for calculating the above target combination number is not limited, and in addition to the above two calculation methods, a calculation method for the number of terminal reported combinations newly defined in a subsequent protocol version may also be adopted.

[0041] In an embodiment of the present application, the first table is a table acquired in advance by the terminal for determining the number of combinations, and the table may be defined by a protocol or set on the network side. In the table, the columns represent candidate values ​​of y in the number of combinations C(x,y), and the rows represent candidate values ​​of x in the number of combinations C(x,y), and the value of the number of combinations C(x,y) can be looked up in the table according to the values ​​of x and y. For example, the first table may be as shown in Table 1.

[0042] [Table 1] In Table 1 above, the candidate values ​​for y are 1 to 15, and the candidate values ​​for x are 1 to 15. Thus, in the process of determining the target number of combinations, the number of combinations of any combination of y values ​​from 1 to 15 and x values ​​from 0 to 15 can be determined from the table above.

[0043] In the embodiment of the present application, since the maximum value indicated in the columns in the first table is greater than half of the maximum value indicated in the rows, it is possible to support selecting and reporting more elements in the entire sequence, i.e., reporting the number of combinations of longer sequences. For example, taking the above table as an example, it supports reporting the number of combinations for a sequence length of up to 16. That is, the terminal can select up to 16 elements from the entire sequence and report the corresponding number of combinations.

[0044] In the embodiments of the present application, a sequence includes one or more elements, and the length of a sequence can be understood as the number of elements.

[0045] In the embodiment of the present application, the first condition is a condition that the actual values ​​of x and y must satisfy when calculating C(x,y) in the process of calculating the number of combinations, for example, x / 2>=y. Since the number of combinations of the first and second values ​​for the third value is the same, the number of combinations of the two values ​​can be determined based on the table lookup result of one of the values. For example, for c(8,6) and c(8,2), the number of combinations corresponding to c(8,6) and c(8,2) can be obtained by table lookup for c(8,2), which further reduces the table size, saves storage space, and supports the terminal to report the number of combinations of longer sequences, thereby improving the performance of the terminal reporting the number of combinations.

[0046] In an embodiment of the present application, the total sequence is a sequence consisting of all candidate elements. For example, if the sequence length of the total sequence is 8, then N is equal to 8, the indices of the 8 elements are 0, 1, 2, 3, 4, 5, 6, and 7, respectively. If the terminal selects elements with indices 0, 1, 3, 4, 5, and 6, then L is equal to 6, and the reverse sequence is a sequence consisting of elements 2 and 7.

[0047] In the embodiment of the present application, when the length of the sequence selected by the terminal is greater than half the length of the entire sequence, the target combination number can be set to the combination number corresponding to the reverse sequence, and the network side device can analyze the reverse sequence according to the target combination number, thereby deriving the sequence selected by the terminal from the reverse sequence. In this way, the sequence length for calculating the number of combinations can be reduced, and the calculation overhead of the terminal can be further reduced. Since the elements for calculating the number of combinations are reduced, the number of table lookups for calculating the number of combinations can also be reduced.

[0048] In the embodiment of the present application, when the target combination number is the combination number obtained by subtracting the combination number corresponding to the reverse sequence from the reference combination number, C(N,L)-1-i comHere, C(N,L) represents the number of combinations of N and L, and i com represents the number of combinations corresponding to the above reverse sequence. com is reported, the computational overhead of the terminal can be reduced, and the network side device can com The terminal can determine the selected sequence according to a method defined in the protocol based on the above.

[0049] In addition, in an embodiment of the present application, when the length of the sequence selected by the terminal is less than or equal to half the sequence length of all the sequences, the target number of combinations is the number of combinations corresponding to the sequence selected by the terminal. In this way, since the length of the sequence selected by the terminal is less than or equal to half the sequence length of all the sequences, the number of combinations corresponding to the sequence selected by the terminal can also reduce the calculation overhead.

[0050] It should be noted that in the embodiments of the present application, in the corresponding embodiment using the first table or the first condition, the target combination number reported by the terminal may be the combination number corresponding to the reverse sequence, or the combination number obtained by subtracting the combination number corresponding to the reverse sequence from the reference combination number, or the combination number corresponding to the sequence selected by the terminal, but is not limited thereto.

[0051] In the embodiment of the present application, the first table and the operation corresponding to the first condition can support the terminal to report the number of combinations corresponding to a longer sequence, and the operation corresponding to the reverse sequence can reduce the complexity of the number of combinations calculated by the terminal and the complexity of sequence recovery by the network side device. From the above, it can be seen that the embodiment of the present application can improve the performance of the terminal's reporting of the number of combinations.

[0052] In the embodiment of the present application, the application scenario of the combination number reporting is not limited, for example, it can be applied to a channel state information (CSI) reporting scenario, that is, the target combination number can be reported by putting it into CSI. In this scenario, the elements in the sequence can be an orthogonal basis, and a multi-dimensional orthogonal basis can be reported. For example, there are N1 candidate elements in the first dimension, belonging to the set {0, ..., N1-1}, and there are N2 candidate elements in the second dimension, belonging to the set {0, ..., N2-1}. The global element combined in the two dimensions belongs to the set {0, ..., N1N2-1}. The terminal needs to select L orthogonal bases from the N1N2 orthogonal bases (i.e., N is equal to N1N2) and report them to the network side device. For example, it can also be applied to a scenario in which reporting the combination number reduces reporting overhead, and is not limited thereto.

[0053] In an alternative embodiment, the columns of the first table are for representing candidate values ​​of y in C(x,y), the rows of the first table are for representing candidate values ​​of x in C(x,y), in which the maximum candidate value of y is equal to the maximum candidate value of x in the first table, and C(x,y) represents the number of combinations of x and y; In the process of determining the target number of combinations, the value of x is related to the sequence length of the entire sequence, and the value of y is related to the sequence selected by the terminal.

[0054] The first table may be the table shown in Table 1 above, where the maximum candidate value for y in the first table is equal to the maximum candidate value for x, 15. For example, in the first table, the maximum candidate value for y is 15, and the maximum candidate value for x is 15. Of course, the maximum candidate value of 15 is merely an optional embodiment, and the first table may be specifically set according to actual reporting needs. For example, the maximum candidate value for y may be an integer greater than 15, such as 16, 18, 32, and the maximum candidate value for x may be an integer greater than 15, such as 16, 18, 32, and the like.

[0055] The value of x is related to the sequence length of the entire sequence. The value of x is determined by the sequence length of the entire sequence and the index of the element in the sequence selected by the terminal. Regarding that the value of y is related to the sequence selected by the terminal, the value of y can be determined by the length of the sequence selected by the terminal and the elements in the sequence selected by the terminal. For example, the number of combinations corresponding to the i-th element in the sequence selected by the terminal can be expressed as C(N - 1 - n (i) , L - i), that is, for this element, it is N - 1 - n (i) , y is L - i. Thus, based on the values of x and y, the value of the number of combinations can be looked up from the first table.

[0056] In this embodiment, since the maximum candidate value of y in the first table is equal to the maximum candidate value of x, it can support that the length of the sequence selected by the terminal is equal to the length of the entire sequence. Thereby, the terminal can report the number of combinations corresponding to more elements, improving the performance of the terminal's number-of-combinations reporting. For example, according to Table 1 above, it can support up to the case of 16 out of 16 selections.

[0057] It should be noted that in the embodiments of this application, it is not limited that the maximum candidate value of y in the first table is equal to the maximum candidate value of x. For example, in some embodiments, the maximum candidate value of y in the first table is 1 or 2 less than the maximum candidate value of x. For example, the maximum candidate value of x is 15, and the maximum candidate value of y may be 13 or 14, etc.

[0058] Optionally, in the first table, when x < y, the value of the number of combinations is 0.

[0059] In this embodiment, when x < y, it can be realized that the value of the corresponding number of combinations C(x, y) is 0, thereby reducing the complexity of the terminal's calculation of the target number of combinations.

[0060] In one alternative embodiment, the first condition includes x / 2>=y and x, y≠0; where x is equal to the sequence length of the entire sequence minus the index of the i-th element minus 1, y is equal to Li, where i=0,...,L-1, or y is equal to NLi, where L is the length of the sequence selected by the terminal and N is the sequence length of the total sequence, where i=0,...,NL-1.

[0061] The i-th element may be the i-th element in the sequence selected by the terminal or the i-th element in the reverse sequence. Specifically, it depends on whether the target number of combinations is the number of combinations corresponding to the sequence selected by the terminal or is obtained based on the number of combinations corresponding to the reverse sequence. Specifically, the x=N-1-n (i) So, n (i) is the index of the i-th element.

[0062] Specifically, when the target combination number is the combination number corresponding to the sequence selected by the terminal, the i-th element may be the i-th element in the sequence selected by the terminal, and y is equal to Li. When the target combination number is obtained based on the combination number corresponding to the reverse sequence, the i-th element may be the i-th element in the reverse sequence, and y is equal to NLi.

[0063] In this embodiment, when x / 2>=y and x, y≠0, the target combination number is calculated using the above target calculation method, so that the complexity of the target combination number calculation can be reduced.

[0064] It should be noted that in the embodiments of the present application, the first condition is not limited to including x / 2>=y and x, y≠0. For example, in some embodiments, the first condition may be x / 2>=y but not limited to x, y≠0.

[0065] In an embodiment of the present application, under the above first condition, the target combination number may be calculated using the above first table, second table, or other tables defined in the protocol, and this is not limited.

[0066] Optionally, in the target calculation method, the fact that the combination number of the first value and the second value for the third value is the same includes C(x,y)=C(x,x - y), the first value is y, the second value is x - y, and the third value is x, C(x,y) represents the combination number of the combination of x and y, and C(x,x - y) represents the combination number of the combination of x and x - y.

[0067] In this embodiment, when x / 2 >= y and x, y ≠ 0, C(x,y)=C(x,x - y) can be used to reduce the complexity of calculating the target combination number by the terminal.

[0068] As an optional embodiment, when the second condition is satisfied, in the second table for calculating the target combination number, the maximum value indicated by the column is less than or equal to the truncated value of half of the maximum value indicated by the row, or when the first condition is satisfied, in the second table for calculating the target combination number, the maximum value indicated by the column is less than half of the maximum value indicated by the row.

[0069] The method for calculating the target combination number under the above second condition or the second condition includes whether the target combination number is the combination number corresponding to the reverse sequence, or the combination number obtained by subtracting the combination number corresponding to the reverse sequence from the reference combination number, or the combination number corresponding to the sequence selected by the terminal.

[0070] The above second condition is the condition that the actual values of x and y satisfy when calculating C(x,y) in the process of calculating the combination number. For example, in some embodiments, the second condition includes x / 2 < y, or x = y = 0, where x is equal to the sequence length of the entire sequence minus the index of the i-th element minus 1, y is equal to Li, where i=0,...,L-1, or y is equal to NLi, where L is the length of the sequence selected by the terminal and N is the sequence length of the total sequence, where i=0,...,NL-1.

[0071] For the values ​​of x and y, please refer to the corresponding explanations in the above embodiments, and the explanations will be omitted here.

[0072] In this embodiment, in the second table, the maximum value indicated in the column is equal to or less than half the maximum value indicated in the row, which reduces the complexity of the terminal's calculation of the target combination number, reduces the table size, and saves storage space.

[0073] For example, the second table may be as shown in Table 2 or Table 3.

[0074] [Table 2]

[0075] [Table 3]

[0076] Here, "-" in Table 3 above indicates that there is no value at this position, and this index is not calculated but converted to a position with a value by C(x,y)=C(x,xy). Therefore, setting "-" in the table reduces the complexity of the table.

[0077] In Table 2 or Table 3 above, the candidate values ​​for y are 1 to 7, and the candidate values ​​for x are 0 to 15. Thus, in the process of determining the target number of combinations, the number of combinations of any combination of y values ​​from 1 to 7 and x values ​​from 0 to 15 can be determined from the above table.

[0078] It should be noted that in the embodiments of the present application, x and y are not limited to 15 and may be any value. In the embodiments of the present application, Tables 1, 2 and 3 are only described by taking 15 as an example.

[0079] Optionally, in the second table, when x < y, the value of the combination number is 0.

[0080] In this embodiment, when x < y, it can be realized that the value of the corresponding combination number C(x, y) is 0, whereby the complexity of calculating the target combination number by the terminal can be reduced.

[0081] In the embodiments of the present application, under the above second condition, the target combination number may be calculated using the first table, the second table or other tables defined in the protocol, and this is not limited.

[0082] As a selective embodiment, for the terminal to determine the target combination number, when the length of the sequence selected by the terminal is greater than half of the sequence length of all sequences, based on the sequence selected by the terminal, determine the reverse sequence, and based on the index and length of the reverse sequence, generate the combination number corresponding to the reverse sequence.

[0083] To determine the reverse sequence based on the sequence selected by the terminal may be to select all elements other than the sequence selected by the terminal from the above all sequences, and further obtain the reverse sequence. For example, if the sequence length of all sequences is 8, then N is equal to 8, and the indexes of the 8 elements are 0, 1, 2, 3, 4, 5, 6, 7 respectively. If the terminal selects elements with indexes 0, 1, 3, 4, 5, 6, then L is equal to 6, and the reverse sequence is a sequence consisting of elements 2 and 7.

[0084] Generating a combination number corresponding to the reverse sequence based on an index and a length of the reverse sequence may comprise calculating a combination number corresponding to the reverse sequence using the following formula:

[0085] [Number 3] JPEG0007733229000006.jpg2090

[0086] Here, the i com is the number of combinations corresponding to the reverse sequence, N is the sequence length of the full sequence, L is the length of the sequence selected by the terminal, i=0, . . . , NL-1, and m (i) is the index of the i-th element in the reverse sequence, and if the sequence selected by the terminal is the entire sequence, N=L, i com =0.

[0087] If the sequence selected by the terminal is the entire sequence, N=L,i com = 0 means that if the sequence selected by the terminal is all of the total sequences, N = L, no table lookup is required, and i com It can be understood that the calculation was done directly as =0.

[0088] Here, the calculation method can use the first table, the second table provided in the embodiment of the present application, or a table defined in the protocol, but is not limited thereto.

[0089] In addition, in the embodiments of the present application, the calculation method for calculating the number of combinations corresponding to the reverse sequence is not limited, and for example, a method for calculating the number of reported combinations corresponding to multiple elements other than those defined in the protocol may be adopted.

[0090] In this embodiment, if the length of the sequence selected by the terminal is greater than half the length of the entire sequence, the inverse sequence of the sequence selected by the terminal can be first calculated, i.e., a sequence consisting of the indexes of the unselected elements (this sequence can be random or ascending order), and then the number of combinations of this inverse sequence can be calculated as the number of combinations to be finally reported. After receiving this number of combinations, the network side device obtains the indexes of the corresponding elements according to a conventional algorithm, and then determines whether to invert based on the relationship between the selected number and the total number, thereby finally obtaining the sequence selected by the terminal. In this way, the target number of combinations can be obtained by calculating the number of combinations corresponding to the inverse sequence, thereby reducing the reporting overhead of the terminal.

[0091] In an embodiment of the present application, a terminal selects a sequence, and the terminal performs a target action based on the sequence selected by the terminal, the target action including one of determining a target combination number and reporting the target combination number, and not reporting the combination number if the sequence selected by the terminal is all of the entire sequences, and the target combination number is calculated by a target calculation method when a first condition is satisfied: in a first table for calculating the target combination number, the maximum value indicated in a column is greater than half the maximum value indicated in a row, and in the target calculation method, the number of combinations of the first value and the second value for a third value is the same, and the first value and the previous value are the same. and the sum of the second values ​​is the third value, and when the length of the sequence selected by the terminal is greater than half the sequence length of all sequences, the target combination number is the number of combinations corresponding to the reverse sequence, or when the length of the sequence selected by the terminal is greater than half the sequence length of all sequences, the target combination number is the number of combinations obtained by subtracting the number of combinations corresponding to the reverse sequence from the reference combination number, or when the length of the sequence selected by the terminal is equal to or less than half the sequence length of all sequences, the target combination number is the number of combinations corresponding to the sequence selected by the terminal. In the embodiment of the present application, the first table and the operation corresponding to the first condition can support the terminal in reporting the number of combinations corresponding to longer sequences, and the operation corresponding to the reverse sequence can reduce the complexity of the terminal's calculation of the number of combinations and the complexity of sequence recovery by a network side device. From the above, it can be seen that the embodiment of the present application can improve the performance of the terminal's reporting of the number of combinations.

[0092] Referring to FIG. 3, which is a flowchart of the sequence determination method provided in the embodiment of the present application, as shown in FIG.

[0094] The fact that the terminal does not report the combination number can be determined in such a manner that the combination number information reported from the terminal on the specified resource has not been received, or information from the terminal instructing not to report the combination number has been received, etc., and this is not limited thereto.

[0099] Optionally, in the target calculation method, the fact that the combination numbers of the first value and the second value for the third value are the same includes C(x,y) = C(x,x - y), The first value is y, the second value is x - y, and the third value is x, C(x, y) represents the number of combinations of the combination of x and y, and C(x, x - y) represents the number of combinations of the combination of x and x - y.

[0105] It should be noted that this embodiment is an embodiment of a network side device corresponding to the embodiment shown in Fig. 2, and for specific embodiments, reference can be made to the relevant description of the embodiment shown in Fig. 2. In order to avoid repetition, the description will be omitted in this embodiment.

[0106] The methods provided in the examples of this application are illustrated below by several examples.

[0107] Example 1 This embodiment mainly takes as an example whether the sequence length selected by the terminal is greater than half the sequence length of the entire sequence.

[0108] The terminal determines an alpha value (which may represent the ratio of the number of ports to the total number of ports) and the number of Channel State Information Reference Signal (CSI-RS) ports N based on the parameters set by the upper layer. CSI-RS Determine K1=N CSI-RS * Calculate alpha as the number of CSI-RS ports to be selected, and the total number of corresponding combinations to be calculated is N = N CSI-RS / 2, the number of elements to be selected is L=K1 / 2, and the dual polarization ports selected by the terminal are n=[n(0),n(1)...n(L-1)].

[0109] If L<=N / 2, the terminal calculates using the following formula:

[0110] [Number 5] JPEG0007733229000007.jpg1454

[0111] If L>N / 2, the terminal first determines the inverse sequence of the sequence selected by the terminal, i.e., the unselected dual polarization ports m=[m(0),m(1)...m(NL-1)], where m and n are disjoint and the complement is the whole set, i.e., [0,1,2...N-1].

[0112] The terminal then calculates the number of reported combinations as follows:

[0113] [Number 6] JPEG0007733229000008.jpg2091

[0114] The terminal puts this combination number into CSI and feeds it back to the base station, and the base station receives the CSI, and ii com After analyzing, if L<=N / 2, the base station directly calculates the index of the element. The specific process is as follows:

[0115] s i-1 = 0, i = 0, ..., L-1, i com -s i-1 >=C(x * ,NLi), the maximum value within the range of {L-1-i,N-1-i} is x * (find the largest x * in {L-1-i,N-1-i} such as i com -s i-1 >=C(x * ,Li), e i =C(x * ,NLi), s i =s i-1 +ei So, n (i) =N-1-x * is.

[0116] If L>N / 2, s-1=0, s i-1 =0, i=0, ,NL-1, i com -s i-1 >=C(x * ,NLi), the maximum value within the range of {NL-1-i,N-1-i} is x * (find the largest x * in {NL-1-i,N-1-i} such as i com -s i-1 >=C(x * ,NLi), e i =C(x * ,NLi), s i =s i-1 +e i So, n (i) =N-1-x * is.

[0117] Sequence m is obtained and reversed to obtain sequence n as the dual polarization port selected by the terminal.

[0118] Example 2 In this embodiment, the first half of the operation on the terminal side is the same as that in the first embodiment, and therefore the explanation will be omitted here.

[0119] If L>N / 2, the number of combinations is C(N,L)-1-i com Report as.

[0120] The network side device obtains the reported number of combinations based on the feedback content of the CSI, and then calculates n according to the solution method for L<=N / 2 in the first embodiment.

[0121] In the embodiment of the present application, in the process of calculating the number of combinations, if the length of the selected sequence is greater than half the length of the entire sequence, the inverse sequence of the selected sequence is calculated, thereby reducing overhead and reporting the number of combinations of the inverse sequence, or subtracting the number of combinations of the inverse sequence from the total possible value to obtain and report the number of combinations of the normal sequence, thereby reducing the computational complexity of the terminal and the network side equipment.
