[0109] In some embodiments, the acquisition of data, information, etc., may comply with the laws and regulations of the country where the location is situated.

[0111] Furthermore, each element, each row, or each column in the table of this disclosure can be implemented as an independent embodiment, and any combination of any element, any row, or any column can also be implemented as an independent embodiment.

[0112] In some embodiments, to address the problems of large-scale antenna arrays, the industry has proposed sparse arrays (SA). Sparse array antennas reduce antenna sidelobes and save antenna costs by strategically removing some antenna elements, without significantly reducing antenna gain and beamwidth. A sparse array is a non-uniform linear array. That is, a uniform linear array is modified by removing a portion of its elements using a specific optimization method. Figure 1a shows a schematic diagram of the antenna distribution of different arrays. Figure 1b shows a schematic diagram of the direction of different arrays.

[0113] In some embodiments, a problem with sparse arrays is the uneven antenna distribution. Traditional uniform arrays, corresponding to Discrete Fourier Transform (DFT) beams, have the same transmit power for each antenna element (or port), making different DFT beams orthogonal. However, with sparse arrays, the antenna distribution is uneven, and some ports have no antennas. Therefore, determining the CPU (CSI processing unit) usage for CSI feedback in a sparse array is a problem that needs to be solved.

[0114] Typical sparse arrays include the following:

[0115] (1) Coprime Array (CA): CA is a type of sparse array that introduces a closed-form expression for the antenna position. This means that once the number of elements is given, the antenna position can be obtained immediately without any exhaustive search mechanism. CA consists of a Q-element array with an element spacing of Pd and a (2P-1)-element array with an element spacing of Qd, where P and Q are coprime integers such that P is less than Q, and d represents the half-wavelength element spacing.

[0116] For example: Q=3, P=2, Table 1 shows the antenna element positions (or port positions) corresponding to each subarray. That is, the first subarray is a 3-element array with a spacing of 2d, and the corresponding positions are 0d, 2d, and 4d, such as the position "1" in Table 1; the second subarray is a 3-element subarray with a spacing of 3d, and the corresponding positions are 0d, 3d, and 6d, such as the position "2" in Table 1.

[0117] Table 1

[0118] (2) Nested Arrays (NAs): NAs provide another closed form of antenna position representation. A two-level nested array is mainly composed of two nested uniform arrays. Figure 1c is a schematic diagram of a nested array. As shown in Figure 1c, assuming the element spacing of the two uniform arrays is d1 and d2 respectively, and the number of elements is M1 and M2 respectively, then the element spacing of the two uniform arrays satisfies: d2 = (M1 + 1)d1, and the spacing between the first element of the second array and the last element of the first array is also d1. The first array appears to be nested within the second array, forming a nested array. Table 2 is a schematic table showing the element distribution of the subarrays and the array degrees of freedom when the total number of elements in the nested array is M. Table 3 shows the antenna element positions (or port positions) corresponding to each subarray when M1 = 3, M2 = 3, d1 = d, d2 = 4d, where "1" indicates the position of the element in the first subarray, and "2" indicates the position of the element in the second subarray.

[0119] Table 2

[0120] Table 3

[0121] (3) Non-redundant array, or minimum redundancy array. The minimum redundancy array has the lowest redundancy, but the design of this array does not have a clear expression for the position of the array elements, and can only be obtained by exhaustive search by computer. Table 4 shows the correspondence between the number of array elements and the position of array elements in a redundant array.

[0122] Table 4

[0123] Therefore, this disclosure proposes a communication method in which a terminal determines the first CSI processing unit (CPU) occupied by the first Channel State Information (CSI). The first CSI is the CSI to be updated, and the first CSI includes CSIs corresponding to at least two reference signal resources, or CSIs corresponding to at least two port groups of one reference signal resource. Since different subarrays of a sparse array correspond to different reference signal resources or different port groups of the same reference signal resource, the terminal, by determining the first CPU, can accurately determine whether to update the first CSI corresponding to the subarray. This enables the application of coefficient arrays in the communication system, saving costs and energy consumption.

[0124] Figure 1d is a schematic diagram of a communication system architecture according to an embodiment of the present disclosure.

[0125] As shown in Figure 1d, the communication system 100 includes a terminal 101 and a network device 102.

[0126] In some embodiments, terminal 101 includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0127] In some embodiments, network device 102 may include at least one of access network device and core network device.

[0128] In some embodiments, the access network device is, for example, a node or device that connects a terminal to a wireless network.

In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0130] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0131] In some embodiments, a core network device may be a single device comprising one or more network elements, or it may be multiple devices or a group of devices, each comprising all or part of the aforementioned one or more network elements. Network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), or a Next Generation Core (NGC).

As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0135] Figure 2 is a schematic diagram of a communication method interaction according to an embodiment of the present disclosure. As shown in Figure 2, this embodiment of the present disclosure relates to a communication method for a communication system 100, the method including:

[0136] In step S2101, terminal 101 determines the first CPU used to calculate the first CSI.

[0137] In some embodiments, the terminal may determine the first CPU used to calculate the first CSI. The first CSI is the CSI to be updated, and the first CSI includes CSIs corresponding to at least two reference signal resources, or the first CSI includes CSIs corresponding to at least two port groups of one reference signal resource. For example, if each reference signal resource (or each port group) corresponds to one CSI, then the first CSI includes at least two CSIs. Or, for example, if each reference signal resource (or each port group) corresponds to a portion of a CSI, then the first CSI includes a complete CSI.

[0138] In some embodiments, at least two reference signal resources correspond to one array. An array can be divided into multiple subarrays, that is, each reference signal resource can correspond to one subarray. Alternatively, at least two port groups of the same reference signal resource can correspond to different subarrays, that is, each port group can correspond to one subarray. The first CSI can include the CSIs corresponding to at least two subarrays.

[0139] In some embodiments, the port information corresponding to at least two reference signal resources is configured independently, or the port information corresponding to at least two port groups is configured independently. Independent configuration can be understood as the network device configuring port information for different reference signal resources respectively. For example, port information 1 is configured for reference signal resource A, and port information 2 is configured for reference signal resource B. The port information corresponding to port information 1 and port information 2 may be the same or different.

[0140] In some embodiments, port information for at least two port groups is configured independently, or port information for at least two port groups is configured independently. Independent configuration can be understood as the network device configuring port information for different port groups respectively. For example, port information 1 is configured for port group A, and port information 2 is configured for port group B. The port information corresponding to port information 1 and port information 2 may be the same or different.

[0141] In some embodiments, port information includes at least one of the following: the interval between ports; the number of ports; and the port location.

[0142] In some embodiments, the network device may send first information to the terminal, the first information being used to determine port information of at least two reference signal resources, or the first information being used to determine port information of at least two port groups of the same reference signal resource.

[0143] In some embodiments, the first information includes sum(Ni) bits, where Ni bits correspond to Ni second ports. A bit among the Ni bits with a first value corresponds to a first port among the Ni second ports. The first port is at least one of the Ni second ports. Ni is a positive integer. The value of i is 1, or the value of i ranges from 1 to L. sum() is the summation symbol, and sum(Ni) represents the sum of at least one Ni. For example, if i is 1, sum(Ni) = N1. If i ranges from 1 to L, i.e., i = 1, 2, ..., L, then sum(Ni) = N1 + N2 + ... + NL. Assuming L = 2, then i = 1 and 2, sum(Ni) = N1 + N2. L is the number of groups of port information. For example, if sum(Ni) is used to determine two groups of port information, then L = 2; if sum(Ni) is used to determine three groups of port information, then L = 3. This disclosure does not provide examples of all such groups, but is not limited to this.

[0144] For example, i can be 1, sum(Ni) = N1, and the first information includes N1 bits. The bits with the first value among these N1 bits correspond to the first ports among the N1 second ports. For example, the first value can be "1". If the bit value is "1", then the second port corresponding to that bit position can be used as the first port. If the bit value is "0", then the second port corresponding to that bit position is not used as the first port. Of course, the first value being "1" is only an example, and this disclosure is not limited to this. The N1 bits are used to determine at least two sets of port information. The terminal can divide the bits with the first value among the N1 bits into at least two groups, that is, divide the multiple first ports determined from the N1 second ports into at least two groups, with each group of first ports corresponding to a reference signal resource. Or, each group of first ports corresponds to a port group. That is, each group of first ports corresponds to a subarray.

[0145] For example, i can take values ​​from 1 to L, i.e., i = 1, 2, ..., L, sum(Ni) = N1 + N2 + ... + NL. Taking L = 2 as an example, sum(Ni) = N1 + N2, and the first information can include N1 + N2 bits. N1 bits can correspond to N1 second ports, and the position and / or number of first ports can be determined from these N1 second ports; that is, N1 bits can determine the port information corresponding to the first reference signal resource. N2 bits can correspond to N2 second ports, and the position and / or number of first ports can be determined from these N2 second ports; that is, N2 bits can determine the port information corresponding to the second reference signal resource. For example, bits with the first value among the N1 bits correspond to the first group of first ports. Bits with the first value among the N2 bits correspond to the second group of first ports.

[0146] It is understandable that if i is 1, then the port information determined by the first information is the total port information corresponding to at least two reference signal resources or at least two port groups of the same reference signal resource. The terminal can divide the total port information into at least two groups, with each group corresponding to a different reference signal resource or different port groups of the same reference signal resource. If i ranges from 1 to L, then each Ni bit in sum(Ni) is used to determine one group of port information.

[0147] In some embodiments, the array type can be a coprime array. Assuming the parameters Q = 3 and P = 2 for the coprime array, as shown in Table 1, the numbers 0 to 6 in the first row of Table 1 correspond to the seven second ports. The position of "1" in the second row indicates the position of the first port of the first subarray among the seven second ports, and the position of "2" in the second row indicates the position of the first port of the second subarray among the seven second ports. The first information may include sum(Ni) bits, which can be used to determine the port information corresponding to the first and second subarrays of the coprime array, that is, to determine the positions of "1" and "2" as shown in Table 1. For example, i can take values ​​from 1 to L, where L = 2. The first information can include (N1 + N2) bits, where N1 = N2 = 7. The (N1 + N2) bits can be 10101001001001. The first 7 bits are N1 bits, which are used to determine the port information corresponding to the first subarray. The last 7 bits are N2 bits, which are used to determine the port information corresponding to the second subarray. The position of the bit with a value of 1 is the position of the first port among the 7 second ports.

[0148] In some embodiments, the array type can be a nested array. Assuming the parameters of the nested array are M1 = 3, M2 = 3, d1 = d, d2 = 4d, as shown in Table 3, the first row of Table 3 shows 0 to 11, corresponding to 12 second ports. The position of "1" in the second row indicates the position of the first port of the first subarray among the 12 second ports, and the position of "2" in the second row indicates the position of the first port of the second subarray among the 12 second ports. The first information may include sum(Ni) bits, which can be used to determine the port information corresponding to the first and second subarrays of the nested array, that is, to determine the positions of "1" and "2" as shown in Table 1. For example, i can take values ​​from 1 to L, where L = 2. The first information can include (N1 + N2) bits, where N1 = N2 = 12. The (N1 + N2) bits can be 111000000000000100010001. The first 12 bits are N1 bits, which are used to determine the port information corresponding to the first subarray. The last 12 bits are N2 bits, which are used to determine the port information corresponding to the second subarray. The position of the bit with a value of 1 is the position of the first port among the 12 second ports.

[0149] In some embodiments, the array type can be a non-redundant array, or the port information can be determined by including sum(Ni) bits in the first information, which will not be elaborated further in this disclosure.

[0150] In some embodiments, the first information includes sum(Mi) bits and the number of first ports, Wi. The values ​​of sum(Mi) bits are used to indicate one of a variety of combinations of selecting Wi first ports from Ni second ports. For example, sum(Mi) bits are a bitmap. The values ​​of the bitmap indicate one of a variety of combinations of selecting Wi first ports from Ni second ports. The value of i is from 1 to L, where L is the number of groups of port information, and Ni is greater than or equal to Wi. For example, since the configuration information is at least two groups, L is at least 2. Taking L=2 as an example, the value of i is from 1 to L, i.e., i=1 and 2. sum(Mi) = M1 + M2. Ni includes N1 and N2, and Wi includes W1 and W2. The value of the M1 bit can be used to indicate one of a variety of combinations of selecting W1 first ports from N1 second ports. The value of the M2 bit can be used to indicate one of a variety of combinations of selecting W2 first ports from N2 second ports. For example, if a reference signal resource (or port group) corresponds to W1 ports (i.e., first ports) and there are N1 candidate ports (i.e., second ports), then there are multiple combinations of selecting W1 first ports from N1. The network device can indicate one of these multiple combinations through the values ​​of M1 bits. For example, assuming N1 = 32 and W1 = 17, the value of the M1 bits can indicate one of multiple combinations of selecting 17 first ports from 32 second ports. Of course, the specific values ​​mentioned above are merely exemplary, and this disclosure is not limited thereto. N1 and N2 can be the same or different. For example, if N1 and N2 are the same, it can indicate that the two subarrays correspond to the same array. Or, it can indicate that the two subarrays correspond to different arrays, and the number of second ports corresponding to the different arrays is the same. If N1 and N2 are different, it can indicate that the two subarrays correspond to different arrays, and the number of second ports corresponding to the different arrays is different. W1 and W2 can be the same or different. For example, if W1 and W2 are the same, it can indicate that the number of first ports in the first group and the number of first ports in the second group are the same. It is understandable that the position and number W1 of the first port in the first group among the N1 second ports constitute the port information of the first group. The position and number W2 of the first port in the second group among the N2 second ports constitute the port information of the second group.

[0151] For example, taking Table 1 as an example, N1 = N2 = 7, W1 = W2 = 3. If any 3 first ports are randomly selected from the 7 second ports, there are 35 combinations. Therefore, M1 = M2, and it must be an integer greater than or equal to log2(35), for example, M1 = M2 = 6. For example, bit M1 can be 000001, and bit M2 can be 000010. The value 000001 indicates that the second combination out of the 35 combinations has been selected. The value 000010 indicates that the third combination out of the 35 combinations has been selected. Of course, bits M1 being 000001 and bits M2 being 000010 are merely exemplary examples, and this disclosure is not limited to them.

[0152] For example, taking Table 3 as an example, N1 = N2 = 12, W1 = W2 = 3. There are 220 combinations of randomly selecting 3 first ports from the 12 second ports. Therefore, M1 = M2, and M2 is an integer greater than or equal to log2(220), for example, M1 = M2 = 8. For instance, bits M1 can be 00000001, and bits M2 can be 00000010. The value 00000001 indicates that the second combination out of the 220 combinations has been selected. The value 00000010 indicates that the third combination out of the 220 combinations has been selected. Of course, bits M1 being 00000001 and bits M2 being 00000010 are merely exemplary examples, and this disclosure is not limited to them.

[0153] In some embodiments, the first information includes at least two sets of configuration information, each set of configuration information including at least one of the following: the starting position of the first port among N second ports; the interval between two adjacent first ports; the number of first ports; the first port is a port corresponding to a reference signal resource or a port group, and the first port is at least one of the N second ports, where N is a positive integer.

[0154] Optionally, the first information includes at least two sets of configuration information. Each set of configuration information may include the interval between two adjacent first ports and the number of first ports. The starting position of the first port can be defaulted to the first second port among N second ports; that is, the first second port among N second ports is taken as the first first port. The next first port is determined based on this starting position and the interval between two adjacent first ports, and so on, to determine the positions of all first ports. For example, for a coprime array, the configuration information may include the interval between two adjacent first ports and the number of first ports. The terminal can determine the port positions and number of ports corresponding to each subarray of the coprime array based on the configuration information.

[0155] For example, assuming the parameters Q=3 and P=2 for a coprime array, as shown in Table 1, the numbers 0 to 6 in the first row of Table 1 correspond to the seven second ports. The position of "1" in the second row indicates the position of the first port of the first subarray among the seven second ports, and the position of "2" in the second row indicates the position of the first port of the second subarray among the seven second ports. The first information includes two sets of configuration information: one set corresponding to the first subarray and one set corresponding to the second subarray. The first set of configuration information can include the values ​​2 and 3. The value 2 represents the interval between two adjacent first ports, for example, the interval is the number of empty positions between two adjacent first ports plus 1, or the difference in port numbers of the two adjacent first ports in the second ports. The value 3 represents the number of first ports. The terminal can default the first second port among the seven second ports to the starting position of the first port, that is, use the first second port as the first first port of the first subarray. Then, it determines the second first port of the first subarray after a one-empty-position interval (or a one-second-port interval), and then determines the third first port of the first subarray after another one-empty-position interval. The second set of configuration information can include the values ​​3 and 3, where 3 represents the interval between two adjacent first ports. The value 3 also represents the number of first ports. The terminal can default the first of the seven second ports to the starting position of the first ports, that is, use the first second port as the first first port of the second subarray. Then, it determines the second first port of the second subarray after a three-position interval (or a three-port interval), and finally determines the third first port of the second subarray after another three-position interval.

[0156] Optionally, the first information includes at least two sets of configuration information. The first set of configuration information includes the number of first ports. The second set of configuration information includes the number of first ports and the interval between two adjacent first ports. The first set of configuration information is used to determine the first set of port information. Since the first set of configuration information includes the number of first ports, the first second port out of N second ports can be used as the starting position of the first port, and the interval between two adjacent first ports can be defined as d, where d represents half the wavelength. Based on the starting position and the interval d, the position of the first port out of N second ports can be determined. The second set of configuration information is used to determine the second set of port information. Since the second set of configuration information includes the number of first ports, the position after the last first port in the first set of port information, at an interval d, can be used as the starting position of the first port in the second set of port information. The second set of configuration information also includes the interval between two adjacent first ports. Based on the starting position and the interval, the position of the first port out of N second ports can be determined. For example, for a nested array, the first information may include two sets of configuration information. The first set of configuration information is used to determine the port information corresponding to the first subarray of the nested array, and the second set of configuration information can be used to determine the port information corresponding to the second subarray of the nested array.

[0157] For example, assuming the parameters of the nested array are M1=3, M2=3, d1=d, d2=4d, as shown in Table 3, the first row of Table 3 shows 0 to 11, which correspond to 12 second ports respectively. The position of "1" in the second row indicates the position of the first port of the first subarray among the 12 second ports, and the position of "2" in the second row indicates the position of the first port of the second subarray among the 12 second ports. The first information may include two sets of configuration information, namely the first set of configuration information corresponding to the first subarray and the second set of configuration information corresponding to the second subarray. The first set of configuration information may include the value 3, where 3 represents the sum and quantity of the first ports in the first group. That is, the terminal can determine 3 as the quantity of the first ports in the first group, and d as the interval between two adjacent first ports in the first group. The terminal can default the first second port as the starting position of the first ports in the first group, and determine the position of the first ports in the first group by combining the interval and the quantity. The specific determination method is the same as described in the above embodiment, and will not be repeated here. The second set of configuration may include the values ​​3 and 4d. 3 represents the number of first ports in the second group, and 4d represents the interval between two adjacent first ports in the second group. The terminal can determine the position of the first port in the second group as the position after the last port of the first group, with an interval of d. Combining the interval and the number, the position of the first port in the second group is determined. For the specific determination method, please refer to the above embodiment, which will not be repeated in this disclosure.

[0158] In some embodiments, the first information includes at least two sets of configuration information, each set of configuration information including type and parameters, the type and parameters being used to determine port information.

[0159] In some embodiments, the type includes an array type.

[0160] In some embodiments, the type includes a first type, and the parameters include P and Q. The terminal can determine the type as the first type and determine the port information based on P and Q. The terminal can determine Q as the number of first ports in the first group, and the product of P and d1 as the interval between two adjacent first ports in the first group. Here, d1 can be, for example, half the wavelength. (2P-1) can be determined as the number of first ports in the second group, and the product of Q and d1 can be determined as the interval between two adjacent first ports in the second group. P and Q are positive integers. The terminal can determine the position of the first port in the N second ports by taking the first second port in the N second ports as the starting position of the first port and combining it with the interval between two adjacent first ports.

[0161] In some embodiments, the first type may be, for example, a coprime array.

[0162] For example, taking Table 1 as an example, the first information may include: type is coprime array, value 3 and value 2. Value 3 is Q, value 2 is P, and the terminal can determine 3 as the number of first ports in the first group. 2d1 is determined as the interval between two adjacent first ports in the first group. 3 (i.e., 2P-1) is determined as the number of first ports in the second group. 3d1 is determined as the interval between two adjacent first ports in the second group. The starting position of the first port can be defaulted to the position of the first second port. Then the positions of the first ports in the first group correspond to 0, 2d1, and 4d1, respectively, where d1 is half the wavelength, i.e., 0, 2, and 4 in the first row of Table 1, respectively. The positions of the first ports in the second group are 0, 3d1, and 6d1, where d1 is half the wavelength, i.e., 0, 3, and 6 in the first row of Table 1, respectively.

[0163] In some embodiments, the type includes a second type, and the parameter includes N. If N is odd, the terminal can determine (N-1) / 2 as the number of first ports in the first group of ports, (N+1) / 2 as the number of first ports in the second group of ports, d2 as the interval between two adjacent first ports in the first group of ports, and ((N-1) / 2+1)d2 as the interval between two adjacent first ports in the second group of ports. Here, d2 can be, for example, half the wavelength. If N is even, the terminal determines N / 2 as the number of first ports in the first group of ports, N / 2 as the number of first ports in the second group of ports, d2 as the interval between two adjacent first ports in the first group of ports, and (N / 2+1)d2 as the interval between two adjacent first ports in the second group of ports.

[0164] In some embodiments, the second type may be, for example, a nested array.

[0165] For example, taking Table 3 as an example, the first information may include: type is nested array, value is 6. The value 6 represents N. The terminal can determine 3 (i.e., N / 2) as the number of first ports in the first group, d2 as the interval between two adjacent first ports in the first group, 3 (N / 2) as the number of first ports in the second group, and 4d2 as the interval between two adjacent first ports in the second group. For example, the starting position of the first port in the first group can be assumed to be the first second port, then the positions of the first ports in the first group correspond to 0, d2, and 2d2, where d2 is half the wavelength, corresponding to 0, 1, and 2 in the first row of Table 3. The starting position of the first port in the second group can be assumed to be the next second port adjacent to the last first port in the first group, then the positions of the first ports in the second group correspond to 3d2, 7d2, and 11d2, where d2 is half the wavelength, corresponding to 3, 7, and 11 in the first row of Table 3.

[0166] In some embodiments, the first information includes at least two sets of configuration information, each set including a codebook subset restriction (CBSR), which is used to determine the number of first ports. For example, the terminal can determine the value of at least one of n1 and n2 based on the CBSR. n1 and n2 correspond to the number of ports in different dimensions, such as the number of ports in the horizontal dimension and the number of ports in the vertical dimension.

[0167] In some embodiments, the CBSRs indicate different reference signal resources separately. "Indicate separately" can be understood as each CBSR determining the number of first ports corresponding to a reference signal resource. For example, the first information may include multiple CBSRs, each determining the number of first ports corresponding to a reference signal resource, and the number of first ports determined by different CBSRs may be the same or different. For example, one CBSR indicates that the number of first ports corresponding to a reference signal resource is A, and another CBSR indicates that the number of first ports corresponding to a reference signal resource is B. Or, for example, one CBSR indicates that the number of first ports corresponding to a reference signal resource is A, and another CBSR indicates that the number of first ports corresponding to a reference signal resource is A.

[0168] In some embodiments, for different port groups of the same reference signal resource, the bit string in the CBSR includes at least two parts, each used to determine the number of at least two groups of first ports. For example, the first information includes a CBSR, in which the bit string includes at least two parts, each part used to determine the number of a group of first ports.

[0169] In some embodiments, if the first information includes a CBSR, the first information may also include a type. The CBSR is used to determine the number of first ports, and the type is used to determine the interval between two adjacent first ports, thereby determining the position of the first ports among N second ports.

[0170] In some embodiments, the type includes an array type.

[0171] For example, let's say the type is Type 1. The number of first ports in the two sets of port information determined by the terminal based on CBSR are Q and (2P-1), respectively. Then, the intervals between two adjacent first ports are Pd and Qd, where Pd represents the product of P and d1, and d1 can be, for example, half the wavelength. That is, if the number of first ports in the first set of ports is determined based on CBSR, then multiplying this number by d1 gives the interval between two adjacent first ports in the second set of ports. If the number of first ports in the second set of port information is determined based on CBSR, then adding 1 to this number and dividing by 2, then multiplying the result by d1, gives the interval between two adjacent first ports in the first set of ports. The starting position of the first ports in both the first and second sets of port information can be the first second port among N second ports. The interval between two adjacent first ports in each set of first ports can be determined based on the type and the number of first ports, and the position of each set of first ports can be determined based on the interval and the starting position. Taking Table 1 as an example, the terminal can determine the values ​​3 and 2 based on CBSR. Value 3 is Q, and value 2 is P. The terminal can determine 3 as the number of first ports in the first set. Let 2d1 be the interval between two adjacent first ports in the first group. Let 3 (i.e., 2P-1) be the number of first ports in the second group. Let 3d1 be the interval between two adjacent first ports in the second group. The starting position of the first port can be assumed to be the position of the first second port. Therefore, the positions of the first ports in the first group correspond to 0, 2d1, and 4d1, where d1 is half the wavelength, corresponding to 0, 2, and 4 in the first row of Table 1, respectively. The positions of the first ports in the second group are 0, 3d1, and 6d1, where d1 is half the wavelength, corresponding to 0, 3, and 6 in the first row of Table 1, respectively.

[0172] For example, the array type is type two. The number of first ports in the two sets of port information determined by the terminal based on the CBSR are M1 and M2 respectively. The interval between two adjacent first ports in the first set is d2, which can be, for example, half the wavelength. The interval between two adjacent first ports in the second set is (M1+1)d2. Taking Table 3 as an example, the terminal can determine the value 3 based on the CBSR, i.e., M1 = M2 = 3. The terminal can determine d2 as the interval between two adjacent first ports in the first set, and 4 (i.e., M1+1 = 4)d2 as the interval between two adjacent first ports in the second set. For example, the starting position of the first set of first ports can be assumed to be the first second port, then the positions of the first ports in the first set correspond to 0, d2, and 2d2 respectively, where d2 is half the wavelength, i.e., 0, 1, and 2 in the first row of Table 3. The starting position of the first port of the second group can be assumed to be the next second port adjacent to the last first port of the first group. Then the positions of the first ports of the second group correspond to 3d2, 7d2 and 11d2 respectively, where d2 is half of the wavelength, which corresponds to 3, 7 and 11 in the first row of Table 3.

[0173] In some embodiments, the name of the first information is not limited, and it may be, for example, "first configuration information".

[0174] In some embodiments, the CSI corresponding to at least two reference signal resources or at least two port groups includes spatial vector information. That is, the first CSI may include spatial vector information corresponding to at least two reference signal resources. Alternatively, the first CSI may include spatial vector information corresponding to at least two port groups. The spatial vector information includes at least one of the following: a first parameter, used to indicate at least one of N1*O1 vectors, where N1 represents the number of ports in the first dimension and O1 represents the number of parameters in the first dimension; a second parameter, used to indicate at least one of N2*O2 vectors, where N2 represents the number of ports in the second dimension and O2 represents the number of parameters in the second dimension; a third parameter, used to indicate at least one of N1*N2 vectors; a fourth parameter, used to indicate at least one of O1*O2 vectors; a strongest vector indicator; and coefficient information.

[0175] Optionally, the spatial vector information may include a first parameter, which indicates at least one of the N1*O1 vectors. Here, N1 may represent the number of ports in the first dimension, and O1 may represent the number of parameters in the first dimension. For example, the number of parameters may be the number of oversampled samples or the number of beams; that is, O1 may represent the number of oversampled samples or the number of beams in the first dimension. The spatial vector may also be a beam, and O1 may represent the number of vectors corresponding to each port in the first dimension. The terminal may select at least one vector from the N1*O1 vectors as a vector for a reference signal resource (or port group, or subarray), and indicate this selection through the first parameter in the spatial vector information.

[0176] Optionally, the spatial vector information may include a second parameter indicating at least one of the N2*O2 vectors. Here, N2 may represent the number of ports in the second dimension, and O2 may represent the number of parameters in the second dimension. For example, the number of parameters may be the number of oversampled samples or the number of beams; that is, O2 may represent the number of oversampled samples or the number of beams in the second dimension. The spatial vector may also be a beam, and O2 may represent the number of vectors corresponding to each port in the second dimension. The terminal may select at least one vector from the N2*O2 vectors as a vector for a reference signal resource (or port group, or subarray), and indicate this selection through the first parameter in the spatial vector information.

[0177] The first and second dimensions can be horizontal and vertical, respectively. For example, the first dimension can be horizontal and the second dimension can be vertical, or vice versa, but this is not a limitation. Dimensions can also represent planning directions. That is, the first dimension can be the first polarization direction, and the second dimension can be the second polarization direction.

[0178] Optionally, the spatial vector information may include a third parameter indicating at least one of the N1*N2 vectors. The terminal may select at least one vector from the N1*N2 vectors as a vector for a reference signal resource (or port group, or subarray) and indicate this via the third parameter in the spatial vector information.

[0179] Optionally, the spatial vector information may include a fourth parameter indicating at least one of the O1*O2 vectors. The terminal may select at least one vector from the O1*O2 vectors as a vector for a reference signal resource (or port group, or subarray) and indicate this via the fourth parameter in the spatial vector information.

[0180] Optionally, the spatial vector information may include a strongest vector indicator, for example, indicating the overall strongest vector among the vectors corresponding to at least two reference signal resources. Alternatively, it may indicate the locally strongest vector among the vectors corresponding to each reference signal resource. The strongest vector may be the one with the highest magnitude value in the pointer.

[0181] In some embodiments, the CSI corresponding to at least two reference signal resources or at least two port groups may include coefficient information. That is, the first CSI may include coefficient information corresponding to at least two reference signal resources. Alternatively, the first CSI may include coefficient information corresponding to at least two port groups.

[0182] In some embodiments, the coefficient information includes at least one of the following: nonzero coefficients indication; strongest coefficient indication; amplitude coefficient corresponding to the nonzero coefficient; phase coefficient corresponding to the nonzero coefficient.

[0183] Optionally, the coefficient information may include a non-zero coefficient indicator. This can be understood as the coefficient information relating to the coefficients of the vectors corresponding to the subarray. Alternatively, it can be understood as the coefficient information relating to the coefficients of vectors corresponding to different reference signal resources (or different port groups of the same reference signal resource). The non-zero coefficient indicator can indicate which (or which) vectors among the vectors corresponding to at least two reference signal resources (or different port groups of the same reference signal resource) have non-zero coefficients. For example, if the first subarray has L1 spatial vectors and M1 frequency vectors, and the second subarray has L2 spatial vectors and M2 frequency vectors, then the non-zero coefficient indicator can be used to indicate at least one of (L1*M1 + L2*M2). For example, if a reference signal resource corresponds to 5 vectors, and the coefficient of the first vector among the 5 vectors is non-zero while the coefficients of the other vectors are zero, then 5 bits, such as 10000, can be used to indicate that the coefficient of the first vector among the 5 vectors is non-zero. 10000 is one form of non-zero coefficient indication. Of course, this disclosure is not limited to this; 10000 is merely an exemplary example. Non-zero coefficient indication can also be called non-zero coefficient position indication. Non-zero coefficient position refers to the position of a non-zero coefficient among multiple coefficients, that is, the position of a vector with non-zero coefficients among multiple vectors.

[0184] Optionally, the coefficient information may include a strongest coefficient indicator. The strongest coefficient indicator may indicate which (or several) vectors among the vectors corresponding to each reference signal resource (or each port group of the same reference signal resource) has the strongest coefficient; this is referred to in this disclosure as a local strongest coefficient indicator. For example, the first subarray has L1 spatial vectors and M1 frequency vectors, and the second subarray has L2 spatial vectors and M2 frequency vectors. The coefficients of (L1*M1) vectors include N1 non-zero coefficients, and the coefficients of (L2*M2) vectors include N2 non-zero coefficients. Then, the local strongest coefficient indicator may indicate one of N1 and one of N2, respectively, that is, indicating which of the N1 non-zero coefficients is the local strongest coefficient, and indicating which of the N2 non-zero coefficients is the local strongest coefficient. For example, the local strongest coefficient indicator includes log2(N1) bits, the values ​​of which log2(N1) bits are used to indicate which of the N1 non-zero coefficients is the local strongest coefficient. The indicator includes log2(N2) bits, the values ​​of which of the N2 non-zero coefficients is the local strongest coefficient. The strongest coefficient indicator can indicate which (or which) vectors among the vectors corresponding to at least two reference signal resources (or at least two port groups of the same reference signal resource) have the strongest coefficient; this disclosure refers to this as the overall strongest coefficient indicator. For example, the first subarray has L1 spatial vectors and M1 frequency vectors, and the second subarray has L2 spatial vectors and M2 frequency vectors. Since (L1*M1) coefficients include N1 non-zero coefficients, and (L2*M2) coefficients include N2 non-zero coefficients, the overall strongest coefficient indicator can indicate one of (N1+N2), that is, it indicates which of the (N1+N2) non-zero coefficients is the overall strongest coefficient. For example, the overall strongest coefficient can include log2(N1+N2) bits, whose values ​​indicate which of the (N1+N2) non-zero coefficients is the overall strongest coefficient. This strongest coefficient indicator can also be called the strongest coefficient position indicator; for example, the overall strongest coefficient indicator can be called the overall strongest coefficient position indicator, and the local strongest coefficient indicator can be called the local strongest coefficient position indicator, but the name is not limited to these terms. The strongest coefficient position can be the position of the strongest coefficient among multiple non-zero coefficients, that is, the position of the vector with the strongest coefficient among multiple vectors with non-zero coefficients.

[0185] Optionally, the coefficient information may include the amplitude coefficients corresponding to non-zero coefficients. The amplitude coefficients corresponding to non-zero coefficients are relative values, including at least one of the following: the relative amplitude value of the non-zero coefficient relative to the overall strongest coefficient; and the relative amplitude value of the non-zero coefficient relative to the local strongest coefficient. For example, the amplitude coefficient corresponding to a non-zero coefficient may be the amplitude difference or ratio between the actual amplitude of the non-zero coefficient and the actual amplitude of the overall strongest coefficient. As another example, the amplitude coefficient corresponding to a non-zero coefficient may be the amplitude difference or ratio between the actual amplitude of the non-zero coefficient and the actual amplitude of the local strongest coefficient.

[0186] For example, the first subarray has L1 spatial vectors and M1 frequency vectors, and the second subarray has L2 spatial vectors and M2 frequency vectors. The (L1*M1) coefficients include N1 non-zero coefficients, and the (L2*M2) coefficients include N2 non-zero coefficients. If the overall strongest coefficient is among the N1 non-zero coefficients: Optionally, the coefficient information may include the relative magnitudes of the other non-zero coefficients (excluding the strongest coefficient) relative to the overall strongest coefficient. The coefficient information may also include the relative magnitudes of the N2 non-zero coefficients relative to the overall strongest coefficient. Optionally, the coefficient information may include the relative magnitudes of the other non-zero coefficients (excluding the strongest coefficient) relative to the overall strongest coefficient. The coefficient information may also include the relative magnitudes of the locally strongest coefficient among the N2 non-zero coefficients relative to the locally strongest coefficient.

[0187] Optionally, the coefficient information may include the phase coefficients corresponding to non-zero coefficients. The phase coefficients corresponding to non-zero coefficients are relative values, including at least one of the following: the phase relative value of the non-zero coefficient relative to the overall strongest coefficient; the phase relative value of the non-zero coefficient relative to the locally strongest coefficient. For example, the phase coefficient corresponding to a non-zero coefficient may be the phase difference or phase ratio between the actual phase of the non-zero coefficient and the actual phase of the overall strongest coefficient. As another example, the phase coefficient corresponding to a non-zero coefficient may be the phase difference or phase ratio between the actual phase of the non-zero coefficient and the actual phase of the locally strongest coefficient.

[0188] For example, the first subarray has L1 spatial vectors and M1 frequency vectors, and the second subarray has L2 spatial vectors and M2 frequency vectors. The (L1*M1) coefficients include N1 non-zero coefficients, and the (L2*M2) coefficients include N2 non-zero coefficients. If the overall strongest coefficient is among the N1 non-zero coefficients: Optionally, the coefficient information may include the phase relative values ​​of the other non-zero coefficients (excluding the strongest coefficient) relative to the overall strongest coefficient. The coefficient information may also include the phase relative values ​​of the N2 non-zero coefficients relative to the overall strongest coefficient. Optionally, the coefficient information may include the phase relative values ​​of the other non-zero coefficients (excluding the strongest coefficient) relative to the overall strongest coefficient. The coefficient information may also include the amplitude relative values ​​of the locally strongest coefficient among the N2 non-zero coefficients relative to the locally strongest coefficient.

[0189] In some embodiments, the non-zero coefficient indication includes at least one of the following: a bit field, wherein different portions of the bit field are used to indicate the non-zero coefficient positions corresponding to different reference signal resources; a bit field, wherein different portions of the bit field are used to indicate the non-zero coefficient positions corresponding to different port groups; multiple bit fields, wherein different bit fields are used to indicate the non-zero coefficient positions corresponding to different reference signal resources; and multiple bit fields, wherein different bit fields are used to indicate the non-zero coefficient positions corresponding to different port groups. The bit field may also be an information field.

[0190] Optionally, the non-zero coefficient indication may include a bit field. Different parts of a bit field may be used to indicate the non-zero coefficient positions corresponding to different reference signal resources, or to indicate the non-zero coefficient positions corresponding to different port groups of the same reference signal resource. For example, each part may be used to indicate the non-zero coefficient position of a reference signal resource (or a port group). The non-zero coefficient position is the position of the non-zero coefficient among multiple coefficients, i.e., the position of the vector with non-zero coefficients among multiple vectors. Taking a sparse array comprising two subarrays as an example, the first information includes coefficient information for two reference signal resources (or two port groups of a reference signal resource). The first part of a bit field indicates the non-zero coefficient position of the first subarray, and the second part indicates the non-zero coefficient position of the second subarray. Assume the first subarray has L1 spatial vectors and M1 frequency vectors, and the second subarray has L2 spatial vectors and M2 frequency vectors. A bit field contains a total of (L1*M1 + L2*M2) bits, where the first L1*M1 bits correspond to the first subarray, and the last L2*M2 bits correspond to the second subarray. The bit value at each bit position in the bit field is a specified value, such as "1", which indicates that the coefficient corresponding to that bit position is a non-zero coefficient, but it is not limited to this.

[0191] Optionally, the non-zero coefficient indication may include multiple bit fields. Different bit fields are used to indicate the non-zero coefficient positions corresponding to different reference signal resources, or to indicate the non-zero coefficient positions corresponding to different port groups of the same reference signal resource. For example, each bit field is used to indicate the non-zero coefficient position of a reference signal resource (or a port group). For example, the first bit field includes L1*M1 bits, corresponding to the first subarray. The second bit field includes L2*M2 bits, corresponding to the second subarray.

[0192] In some embodiments, the strongest coefficient indication includes at least one of the following: an overall strongest coefficient indication; and a local strongest coefficient indication. The overall strongest coefficient indication can indicate which (or several) of the vectors corresponding to at least two reference signal resources (or different port groups of the same reference signal resource) has the strongest coefficient. The local strongest coefficient indication can indicate which (or several) of the vectors corresponding to each reference signal resource (or each port group of the same reference signal resource) has the strongest coefficient.

[0193] Optionally, the overall strongest coefficient indicator can indicate which (or which) vectors among the vectors corresponding to at least two reference signal resources (or different port groups of the same reference signal resource) has the strongest coefficient. For example, if the number of non-zero coefficients corresponding to the first reference signal resource or the first port group is K1, and the number of non-zero coefficients corresponding to the second reference signal resource or the second port group is K2, then the overall strongest coefficient indicates which coefficient in K1+K2 is the strongest coefficient. The required number of bits is log2(K1+K2), where log2(K1+K2) represents the logarithm of (K1+K2) to the base 2.

[0194] Optionally, the local strongest coefficient indicator can indicate which (or which) vectors in the vectors corresponding to each reference signal resource (or each port group of the same reference signal resource) has the strongest coefficient. For example, if the number of non-zero coefficients corresponding to the first reference signal resource or the first port group is K1, then the number of bits required to indicate which coefficient in K1 is the strongest coefficient is log2(K1). Similarly, if the number of non-zero coefficients corresponding to the second reference signal resource or the second port group is K2, then the number of bits required to indicate which coefficient in K2 is the strongest coefficient is log2(K2). It should be noted that if the overall strongest coefficient belongs to one of the non-zero coefficients corresponding to the first reference signal resource or the first port group, then the local strongest coefficient corresponding to the first reference signal resource or the first port group is the same as the overall strongest coefficient, and no further indication is needed.

[0195] In some embodiments, the coefficient information includes the amplitude coefficients corresponding to non-zero coefficients.

[0196] Optionally, the coefficient information may include the relative amplitude values ​​of the non-zero coefficients corresponding to each reference signal resource relative to the overall strongest coefficient. For example, the number of non-zero coefficient bits corresponding to the first reference signal resource or the first port group is K1, and the number of non-zero coefficients corresponding to the second reference signal resource or the second port group is K2. The overall strongest coefficient is one of the K1 non-zero coefficients. Then the coefficient information may include the amplitude coefficients corresponding to the other non-zero coefficients among the K1 non-zero coefficients besides the overall strongest coefficient, and the amplitude coefficients corresponding to the K2 non-zero coefficients. That is, the coefficient information may include "the difference or ratio between the actual amplitude of the other non-zero coefficients among the K1 non-zero coefficients besides the overall strongest coefficient and the actual amplitude of the overall strongest coefficient", and "the difference or ratio between the actual amplitude of the K2 non-zero coefficients and the actual amplitude of the overall strongest coefficient".

[0197] Optionally, the coefficient information includes the relative amplitude values ​​of the non-zero coefficients corresponding to each reference signal resource relative to the local strongest coefficient. For example, the number of non-zero coefficients corresponding to the first reference signal resource or the first port group is K1, and the number of non-zero coefficients corresponding to the second reference signal resource or the second port group is K2. The overall strongest coefficient is one of the K1 non-zero coefficients. The K2 non-zero coefficients include one local strongest coefficient, for example, referred to as the first local strongest coefficient. The coefficient information may include the amplitude coefficients corresponding to the other non-zero coefficients among the K1 non-zero coefficients besides the overall strongest coefficient, the amplitude coefficients corresponding to the other non-zero coefficients among the K2 non-zero coefficients besides the second local strongest coefficient, and the amplitude coefficient corresponding to the local strongest coefficient among the K2 non-zero coefficients. That is, the coefficient information may include "the difference or ratio between the actual amplitude of the other non-zero coefficients (excluding the strongest overall coefficient) among the K1 non-zero coefficients" and the actual amplitude of the strongest overall coefficient", "the difference or ratio between the actual amplitude of the other non-zero coefficients (excluding the second strongest local coefficient) among the K2 non-zero coefficients and the actual amplitude of the first strongest local coefficient", and "the difference or ratio between the actual amplitude of the strongest local coefficient and the actual amplitude of the strongest overall coefficient among the K2 non-zero coefficients".

[0198] Optionally, for the group of non-zero coefficients containing the strongest coefficient, the relative amplitude value relative to the strongest coefficient can be reported. For other groups of non-zero coefficients, the relative amplitude value relative to the locally strongest coefficient can be reported. For example, the number of non-zero coefficients corresponding to the first reference signal resource or the first port group is K1, and the number of non-zero coefficients corresponding to the second reference signal resource or the second port group is K2. The K1 non-zero coefficients include the overall strongest coefficient. The K2 non-zero coefficients include the locally strongest coefficient. The coefficient information can include the amplitude coefficients corresponding to the other non-zero coefficients (excluding the overall strongest coefficient) among the K1 non-zero coefficients, the amplitude coefficients corresponding to the other non-zero coefficients (excluding the locally strongest coefficient) among the K2 non-zero coefficients, and the amplitude coefficient corresponding to the locally strongest coefficient among the K2 non-zero coefficients.

[0199] It is understood that this disclosure only uses the first reference signal resource and the second reference signal resource as examples, but the reference signal resource may include more than two, such as a third reference signal resource. This disclosure does not list them all, but is not limited to this.

[0200] In some embodiments, the coefficient information includes the phase coefficients corresponding to non-zero coefficients.

[0201] Optionally, the coefficient information may include the phase relative value of the non-zero coefficients corresponding to each reference signal resource with respect to the overall strongest coefficients.

[0202] Optionally, the coefficient information includes the phase relative values ​​of the non-zero coefficients corresponding to each reference signal resource with respect to the local strongest coefficients.

[0203] Optionally, for the group of non-zero coefficients containing the strongest coefficient, the phase relative value relative to the strongest coefficient can be reported. For other groups of non-zero coefficients, the phase relative value relative to the local strongest coefficient or the phase relative value relative to the overall strongest coefficient can be reported.

[0204] It is understood that the coefficient information includes optional embodiments of phase relative values, and optional embodiments of amplitude relative values ​​can be referred to, which will not be elaborated here.

[0205] In some embodiments, the coefficient information may include at least one of the following: the relative amplitude value of the local strongest coefficient relative to the overall strongest coefficient; and the relative phase value of the local strongest coefficient relative to the overall strongest coefficient. It is understood that this embodiment can be combined with the above embodiments or implemented independently. For example, the coefficient information may include a strongest coefficient indicator and a local strongest coefficient indicator, and further include the amplitude coefficient of the local strongest coefficient and / or the phase coefficient of the local strongest coefficient.

[0206] In some embodiments, the coefficient information includes coefficients of vectors corresponding to at least two reference signal resources. The coefficients include at least one of the amplitude coefficient corresponding to a non-zero coefficient and the phase coefficient corresponding to a non-zero coefficient. The coefficient information is included in the Channel State Information (CSI) report. Higher priority coefficients appear earlier in the CSI report. Lower priority coefficients appear later in the CSI report or are not included in the CSI report. For example, coefficients are included in the CSI report in descending order of priority. If the number of coefficients in the CSI report reaches a threshold, lower priority coefficients can be discarded and not reported.

[0207] In some embodiments, the coefficient information includes coefficients of vectors corresponding to at least two port groups. The coefficients include at least one of the amplitude coefficient corresponding to a non-zero coefficient and the phase coefficient corresponding to a non-zero coefficient. The coefficient information is included in the Channel State Information (CSI) report. Coefficients with higher priority appear earlier in the CSI report. Coefficients with lower priority appear later in the CSI report or are not included in the CSI report. For example, coefficients are included in the CSI report in descending order of priority. If the number of coefficients in the CSI report reaches a threshold, lower-priority coefficients can be discarded and not reported.

[0208] In some embodiments, the priority of coefficients is determined based on at least one of the following methods: coefficients corresponding to a first reference signal resource have a higher priority than coefficients corresponding to a second reference signal resource, and the port corresponding to the first reference signal resource precedes the port corresponding to the second reference signal resource; coefficients corresponding to a first port group have a higher priority than coefficients corresponding to a second port group, and the port corresponding to the first port group precedes the port corresponding to the second port group; coefficients corresponding to a first dimension have a higher priority than coefficients corresponding to a second dimension.

[0209] Optionally, the coefficients corresponding to the first subarray have a higher priority than the coefficients corresponding to the second subarray.

[0210] Optionally, the coefficients corresponding to the first reference signal resource have higher priority than the coefficients corresponding to the second reference signal resource, and the ports corresponding to the first reference signal resource precede the ports corresponding to the second reference signal resource. Specifically, the ports corresponding to the first reference signal resource include either the first or last port of the first reference signal resource; similarly, the ports corresponding to the second reference signal resource include either the first or last port of the second reference signal resource. For example, "the port of the first reference signal resource precedes the port of the second reference signal resource" can be understood as the first port of the first reference signal resource preceding the first port of the second reference signal resource. Another example is "the last port of the first reference signal resource precedes the last port of the second reference signal resource." Yet another example is "the port of the first reference signal resource precedes the port of the second reference signal resource," indicating that the port index of the first reference signal resource is less than the port index of the second reference signal resource. The port index can also be a port identifier (ID). That is, "the port of the first reference signal resource precedes the port of the second reference signal resource" means that the port ID of the first reference signal resource is less than the port ID of the second reference signal resource.

[0211] Optionally, the coefficients corresponding to the first port group have higher priority than the coefficients corresponding to the second port group, and the ports corresponding to the first port group precede the ports corresponding to the second port group. Specifically, the ports corresponding to the first port group include the first or last port corresponding to the first reference signal resource; the ports corresponding to the second port group include the first or last port corresponding to the second reference signal resource. For example, "the ports of the first port group precede the ports of the second port group" can be understood as the first port of the first port group preceding the first port of the second port group. Another example is "the last port of the first port group precedes the last port of the second port group." Yet another example is "the ports of the first port group precede the ports of the second port group," which means that the port index of the first port group is less than the port index of the second port group.

[0212] Optionally, the coefficients corresponding to the first dimension have higher priority than the coefficients corresponding to the second dimension. For example, the first dimension may be horizontal, and the second dimension may be vertical. Or, for example, the first dimension may be vertical, and the second dimension may be horizontal. Of course, horizontal and vertical dimensions are just examples; the priority of coefficients can also be determined based on other dimensions, and this disclosure does not limit this. That is, the priority of the coefficients corresponding to the vector of the first dimension for each reference signal resource is higher than the priority of the coefficients corresponding to the vector of the second dimension for that reference signal resource; the priority of the coefficients corresponding to the vector of the first dimension for each port group is higher than the priority of the coefficients corresponding to the vector of the second dimension for that port group. Here, the dimension can also be called the polarization direction; for example, the first dimension can be the first polarization direction, and the second dimension can be the second polarization direction.

[0213] In some embodiments, the priority value of the coefficient can be referenced to the following formula: Pri(l,i,f)=2·L·υ·π(f)+υ·i+l

[0214] In Formula 1, Pri(l,i,f) represents the priority value of the coefficient; the lower the Pri(l,i,f) value, the higher the priority. L represents the number of spatial vectors. l = 1, 2, ..., v. i = 0, 1, ..., 2L-1. For example, when L = 4, i can take values ​​from 0 to 7. υ is the number of spatial multiplexing streams, also known as the number of layers or rank. Where min represents the minimum value, that is, if Less than but like Greater than 1, then This is related to the codebook index. For example, the coefficients of the spatial vectors corresponding to the first subarray are indicated first, followed by the coefficients of the spatial vectors corresponding to the second subarray. That is, for the coefficients of different subarrays, the priority value is determined based on the following formula. When reporting, coefficients with lower priority values ​​are prioritized; that is, when CSI omissions, coefficients with higher priority values ​​are discarded. The coefficients of different subarrays are represented by the different values ​​of i below. For the first subarray, i takes values ​​of 0, 1, ..., 2L1-1, where L1 is the number of spatial vectors corresponding to the first subarray; for the second subarray, i takes values ​​of 2L1, 2L1+1, ..., 2(L1+L2)-1, where L2 is the number of spatial vectors corresponding to the second subarray. Alternatively, the spatial vectors of two subarrays in one polarization direction are examined first, followed by the spatial vectors of two subarrays in another polarization direction. That is, the value of the first polarization direction i of the first subarray is 0, 1, ..., L1-1; the value of the first polarization direction i of the second subarray is L1, L1+1, ..., L1+L2-1; the value of the second polarization direction i of the first subarray is L1+L2, L1+L2+1, ..., 2L1+L2-1; and the value of the second polarization direction i of the second subarray is 2L1+L2, 2L1+L2+1, ..., 2L1+2L2-1.

[0215] In some embodiments, the value of the first CPU is determined based on at least one of the following: the number of at least two reference signal resources; the number of at least two port groups; the number of subarrays contained in an array corresponding to at least two reference signal resources; the number of subarrays contained in an array corresponding to at least two port groups; the number of reference signal resources that are associated among at least two reference signal resources; the number of transmission and receiving points (TRPs); and the number of panels.

[0216] Optionally, the value of the first CPU can be determined based on the number of at least two reference signal resources. The first CSI includes the CSIs corresponding to at least two reference signal resources. The more reference signal resources there are, the more CSI content is included in the first CSI, and the larger the first CPU is used to calculate the first CSI. That is, the more at least two reference signal resources there are, the larger the value of the first CPU. For example, each subarray corresponds to a Channel State Information-Reference Signal resource (CSI-RS resource) in the Channel Measurement Resource (CMR). The terminal can determine the number of CSI-RS resources included in the CMR based on the CSI measurement configuration information, that is, determine the number of at least two reference signal resources, and thus determine the value of the first CPU based on the number of at least two reference signal resources.

[0217] Optionally, the value of the first CPU can be determined based on the number of at least two port groups. The first CSI includes CSIs corresponding to at least two port groups. The more port groups there are, the more CSI content is included in the first CSI, and the larger the first CPU is used to calculate the first CSI. That is, the more at least two port groups there are, the larger the value of the first CPU.

[0218] Optionally, the value of the first CPU can be determined based on the number of subarrays contained in an array corresponding to at least two reference signal resources. For example, each reference signal resource corresponds to one subarray of the array. The more subarrays the array contains, the more reference signal resources there are, and thus the more CSI content is contained in the first CSI. Alternatively, it can be understood that if the first CSI contains CSIs corresponding to at least two subarrays, then the more subarrays there are, the more CSI content is contained in the first CSI. The more CSI content is contained in the first CSI, the larger the first CPU occupied by the first CSI. That is, the more subarrays the array corresponding to at least two reference signal resources contains, the larger the value of the first CPU.

[0219] Optionally, the value of the first CPU can be determined based on the number of subarrays contained in an array corresponding to at least two port groups. For example, each port group corresponds to one subarray of an array; the more subarrays the array contains, the more port groups there are, and the more CSI content the first CSI contains. Alternatively, it can be understood that if the first CSI contains CSIs corresponding to at least two subarrays, the more subarrays there are, the more CSI content the first CSI contains. The more CSI content the first CSI contains, the larger the first CPU usage of the first CSI. That is, the more subarrays an array corresponding to at least two port groups contains, the larger the value of the first CPU.

[0220] Optionally, the value of the first CPU can be determined based on the number of related reference signal resources among at least two reference signal resources. For example, the reference signal resources among at least two reference signal resources are related. Being related can mean corresponding to the same TRP, the same Panel, or the same Cell, or having the same identifier. Taking corresponding to the same TRP as an example, for instance, if four reference signal resources correspond to the same TRP, then the number of related reference signal resources is 4. The more related reference signal resources there are, the more CSI content is included in the first CSI, and the larger the value of the first CPU. The value of the first CPU can be determined based on the number of related reference signal resources. In this case, the number of reference signal resources corresponding to different TRPs (or different Panels, or different Cells, or different Identifiers) is different. In another case, the number of reference signal resources corresponding to different TRPs (or different Panels, or different Cells, or different Identifiers) is the same, then the total number of reference signal resources can be determined based on the number of related reference signal resources and the number of TRPs (or the number of Panels, or the number of Cells, or the number of Identifiers), as specifically described in the optional embodiments below.

[0221] Optionally, the value of the first CPU can be determined based on the number of related reference signal resources and the number of TRPs in at least two reference signal resources. For example, being related can mean corresponding to the same TRP. If the number of related reference signal resources in each group is the same, taking the same TRP as an example, for instance, if the number of reference signal resources corresponding to each TRP is the same, then the product of the number of TRPs and the number of reference signal resources corresponding to each TRP is the total number of reference signal resources. For example, if the first TRP corresponds to 2 reference signal resources, the second TRP corresponds to 2 reference signal resources, the number of TRPs is 2, and the number of reference signal resources corresponding to each TRP (i.e., the number of related reference signal resources) is 2, then the total number of reference signal resources is 2*2=4, where * is the multiplication sign. The larger the total number of reference signal resources, the more CSI content is included in the first CSI, and the larger the value of the first CPU. The value of the first CPU can be determined based on the total number of reference signal resources. When the number of reference signal resources corresponding to different TRPs is different, then the sum of the number of reference signal resources corresponding to multiple TRPs is the total number of reference signal resources.

[0222] Optionally, the value of the first CPU can be determined based on the number of related reference signal resources in at least two reference signal resources and the number of panels. For example, being related can mean corresponding to the same panel. If the number of related reference signal resources in each group is the same, taking the same panel as an example, for instance, if the number of reference signal resources corresponding to each panel is the same, then the product of the number of panels and the number of reference signal resources corresponding to each panel is the total number of reference signal resources. For example, if the first panel corresponds to 2 reference signal resources and the second panel corresponds to 2 reference signal resources, the number of panels is 2, and the number of reference signal resources corresponding to each panel (i.e., the number of related reference signal resources) is 2, then the total number of reference signal resources is 2*2=4, where * is the multiplication sign. The larger the total number of reference signal resources, the more CSI content is included in the first CSI, and the larger the value of the first CPU. The value of the first CPU can be determined based on the total number of reference signal resources. When different panels correspond to different numbers of reference signal resources, the sum of the number of reference signal resources corresponding to multiple panels is the total number of reference signal resources.

[0223] Optionally, the value of the first CPU can be determined based on the number of related reference signal resources and the number of cells in at least two reference signal resources. For example, being related can mean corresponding to the same cell. If the number of related reference signal resources in each group is the same, taking corresponding to the same cell as an example, for instance, if the number of reference signal resources corresponding to each cell is the same, then the product of the number of cells and the number of reference signal resources corresponding to each cell is the total number of reference signal resources. For example, if the first cell corresponds to 2 reference signal resources and the second cell corresponds to 2 reference signal resources, the number of cells is 2, and the number of reference signal resources corresponding to each cell (i.e., the number of related reference signal resources) is 2, then the total number of reference signal resources is 2*2=4, where * is the multiplication sign. The larger the total number of reference signal resources, the more CSI content is included in the first CSI, and the larger the value of the first CPU. The value of the first CPU can be determined based on the total number of reference signal resources. When the number of reference signal resources corresponding to different cells is different, then the sum of the number of reference signal resources corresponding to multiple cells is the total number of reference signal resources.

[0224] Optionally, the value of the first CPU can be determined based on the number of related reference signal resources and the number of identifiers in at least two reference signal resources. For example, being related can mean corresponding to the same identifier. If the number of related reference signal resources in each group is the same, taking the same identifier as an example, if the number of reference signal resources corresponding to each identifier is the same, then the product of the number of identifiers and the number of reference signal resources corresponding to each identifier is the total number of reference signal resources. For example, if the first identifier corresponds to 2 reference signal resources, the second identifier corresponds to 2 reference signal resources, the number of identifiers is 2, and the number of reference signal resources corresponding to each identifier (i.e., the number of related reference signal resources) is 2, then the total number of reference signal resources is 2*2=4, where * is the multiplication sign. The larger the total number of reference signal resources, the more CSI content is included in the first CSI, and the larger the value of the first CPU. The value of the first CPU can be determined based on the total number of reference signal resources. When the number of reference signal resources corresponding to different identifiers is different, then the sum of the number of reference signal resources corresponding to multiple identifiers is the total number of reference signal resources.

[0225] Optionally, the value of the first CPU can be determined based on the number of port groups with a relationship in at least two port groups. For example, the port groups in at least two port groups are related. A relationship can mean corresponding to the same TRP, the same Panel, or having the same identifier. Taking the same TRP as an example, if four port groups correspond to the same TRP, then the number of port groups with a relationship is 4. The more port groups with a relationship, the more CSI content is included in the first CSI, and the larger the value of the first CPU. The value of the first CPU can be determined based on the number of port groups with a relationship. In this case, the number of port groups corresponding to different TRPs (or different Panels, different identifiers) is different. In another case, the number of port groups corresponding to different TRPs (or different Panels, different identifiers) is the same, and the total number of port groups can be determined based on the number of port groups with a relationship and the number of TRPs (or the number of Panels, or the number of identifiers), as detailed in the optional embodiments below.

[0226] Optionally, the value of the first CPU can be determined based on the number of port groups with a relationship in at least two port groups and the number of TRPs. For example, a relationship can refer to corresponding to the same TRP. If the number of port groups with a relationship is the same in each group, taking the same TRP as an example, for instance, if the number of port groups corresponding to each TRP is the same, then the product of the number of TRPs and the number of port groups corresponding to each TRP is the total number of port groups. For example, if the first TRP corresponds to 2 port groups and the second TRP corresponds to 2 port groups, the number of TRPs is 2, and the number of port groups corresponding to each TRP (i.e., the number of port groups with a relationship) is 2, then the total number of port groups is 2*2=4, where * is the multiplication sign. The more port groups there are in the first CSI, the more CSI content is included, and the larger the value of the first CPU. The value of the first CPU can be determined based on the total number of port groups. When different TRPs correspond to different numbers of port groups, the sum of the number of port groups corresponding to multiple TRPs is the total number of port groups.

[0227] Optionally, the value of the first CPU can be determined based on the number of related port groups in at least two port groups and the number of panels. For example, being related can mean corresponding to the same panel. If the number of related port groups in each group is the same, taking the same panel as an example, if the number of port groups corresponding to each panel is the same, then the product of the number of panels and the number of port groups corresponding to each panel is the total number of port groups. For example, if the first panel corresponds to 2 port groups and the second panel corresponds to 2 port groups, the number of panels is 2, and the number of port groups corresponding to each panel (i.e., the number of related port groups) is 2, then the total number of port groups is 2*2=4, where * is the multiplication sign. The more port groups there are in the first CSI, the more CSI content is included, and the larger the value of the first CPU. The value of the first CPU can be determined based on the total number of port groups. When different panels correspond to different numbers of port groups, the sum of the number of port groups corresponding to multiple panels is the total number of port groups.

[0228] Optionally, the value of the first CPU can be determined based on the number of related port groups and the number of cells in at least two port groups. For example, being related can mean corresponding to the same cell. If the number of related port groups in each group is the same, taking the same cell as an example, if the number of port groups corresponding to each cell is the same, then the product of the number of cells and the number of port groups corresponding to each cell is the total number of port groups. For example, if the first cell corresponds to 2 port groups, the second cell corresponds to 2 port groups, the number of cells is 2, and the number of port groups corresponding to each cell (i.e., the number of related port groups) is 2, then the total number of port groups is 2*2=4, where * is the multiplication sign. The more port groups there are in the first CSI, the more CSI content is included, and the larger the value of the first CPU. The value of the first CPU can be determined based on the total number of port groups. When different cells correspond to different numbers of port groups, the sum of the number of port groups corresponding to multiple cells is the total number of port groups.

[0229] Optionally, the value of the first CPU can be determined based on the number of associated port groups and the number of identifiers in at least two port groups. For example, being associated can mean corresponding to the same identifier. If the number of associated port groups in each group is the same, taking the same identifier as an example, if the number of port groups corresponding to each identifier is the same, then the product of the number of identifiers and the number of port groups corresponding to each identifier is the total number of port groups. For example, if the first identifier corresponds to 2 port groups and the second identifier corresponds to 2 port groups, the number of identifiers is 2, and the number of port groups corresponding to each identifier (i.e., the number of associated port groups) is 2, then the total number of port groups is 2*2=4, where * is the multiplication sign. The more port groups there are in the first CSI, the more CSI content is included, and the larger the value of the first CPU is. The value of the first CPU can be determined based on the total number of port groups. When the number of port groups corresponding to different identifiers is different, then the sum of the number of port groups corresponding to multiple identifiers is the total number of port groups.

[0230] In some embodiments, the association relationship of reference signal resources can indicate that the reference signal resources correspond to the same identifier. This association may include at least one of the following: association ID; linking ID; transmit / receive point ID; panel ID; resource set ID; resource group ID; resource subset ID; pair ID; array ID, but is not limited to these.

[0231] In step S2102, in response to the sum of the first CPU and the second CPU exceeding the maximum CPU supported by the terminal 101, the terminal 101 updates at least one of the first CSI and the second CSI based on the priority of the first CSI and the second CSI.

[0232] In some embodiments, network device 102 may determine at least one of the updated first CSI and second CSI. For example, when a terminal updates the first CSI, it may send a CSI report corresponding to the first CSI to the network device, and network device 102 may determine the updated first CSI by receiving the CSI report corresponding to the first CSI sent by the terminal. Correspondingly, when a terminal updates the second CSI, it may send a CSI report corresponding to the second CSI to the network device, and network device 102 may determine the updated second CSI by receiving the CSI report corresponding to the second CSI sent by the terminal.

[0233] In some embodiments, the first CSI is the CSI to be updated, and the first CSI includes the CSI corresponding to at least two reference signal resources, or the CSI corresponding to at least two port groups. Alternatively, it can be understood that the first CSI includes the CSI corresponding to at least two subarrays. There may be other CSIs to be updated in the terminal, such as the second CSI as described in this disclosure. The second CSI is any CSI other than the first CSI that needs to be updated. The CPU used by the second CSI is calculated, referred to in this disclosure as the second CPU. If the sum of the first CPU and the second CPU exceeds the maximum CPU supported by the terminal, the terminal can update at least one of the first CSI and the second CSI based on their priorities. For example, the higher-priority CSI can be updated without updating the lower-priority CSI. Another example is that the higher-priority CSI can be updated first, and the lower-priority CSI can be updated only after the higher-priority CSI update is completed, or when the terminal's CPU can support simultaneous updates.

[0234] In some embodiments, the second CSI may include, for example, beam measurement results, and the corresponding CSI report may be a beam measurement report. Alternatively, the second CSI may include the CSI of the entire array, rather than the CSI of a subarray.

[0235] In some embodiments, both the first CSI and the second CSI are CSIs to be updated. This can be understood as the first CSI and the second CSI needing to be updated at the same time domain location, for example, within the same subframe, the same time slot, or on the same symbol. This disclosure does not provide examples of all such instances.

[0236] In some embodiments, the priority of CSI is determined based on at least one of the following: the time-domain characteristics of the CSI report corresponding to the first CSI; the bearer channel of the CSI report corresponding to the first CSI; the serving cell identifier of the CSI report corresponding to the first CSI; whether the first CSI is Layer 1 reference signal received power (L1-RSRP); and whether the first CSI is Layer 1 signal to interference plus noise ratio (L1-SINR). For example, the following formula 1 can be referenced: Pri iCSI (y,k,c,s)=2·N cells ·M s ·y+N cells ·M s ·k+M s Formula 1 (c+s)

[0237] In Formula 1, PriiCSI (y,k,c,s) represents the priority value; the larger the priority value, the lower the priority. For example, if the first CSI's Pri... iCSI (y,k,c,s) is greater than Pri of the second CSI. iCSI If (y,k,c,s), then the second CSI has higher priority than the first CSI. However, if the terminal has insufficient CPU support, the second CSI can be updated first. c is the serving cell index, N is the number of cells in the first cell, and N is the number of cells in the second cell. cells This is the value of a higher-level parameter (e.g., maxNrofServingCells). s is the report configuration identifier (reportConfigID), M s This is the value of a higher-level parameter (e.g., maxNrofCSI ReportConfigurations). y is a value related to the time-domain type and bearer channel of the CSI report corresponding to the CSI. For example, if the time-domain characteristic of the CSI report is aperiodic and the bearer channel is the Physical Uplink Shared Channel (PUSCH), then the value of y is 0. If the time-domain characteristic of the CSI report is semi-persistent and the bearer channel is PUSCH, then the value of y is 1. If the time-domain characteristic of the CSI report is semi-persistent and the bearer channel is the Physical Uplink Control Channel (PUCCH), then the value of y is 2. If the time-domain characteristic of the CSI report is periodic and the bearer channel is PUCCH, then the value of y is 3. That is, different combinations of the time-domain characteristics and bearer channel of the CSI report affect the value of y, thus affecting Pri. iCSI The value of (y,k,c,s). k is a value related to whether the CSI includes L1-RSRP and / or L1-SINR. For example, if the CSI includes L1-RSRP and / or L1-SINR, then k is 0. If the CSI does not include L1-RSRP and / or L1-SINR, then k is 1. One scenario is that if the CSI includes at least one of L1-RSRP and L1-SINR, k is 0; if the CSI does not include either L1-RSRP or L1-SINR, k is 1. Another scenario is that if the CSI includes L1-RSRP and L1-SINR, k is 0; if the CSI does not include at least one of L1-RSRP and L1-SINR, k is 1.

[0254] In step S5103, network device 102 determines at least one of the updated first channel state information (CSI) and the second CSI.

[0255] In some embodiments, the above methods may include the methods of the embodiments relating to the communication system 100, terminal 101 and network device 102, which will not be described again here.

[0256] This disclosure provides a communication method as follows:

[0257] In some embodiments, the terminal determines the CPU of the first CSI report. When both the first CSI report and the second CSI report need to be updated at this symbol, and when the CPU occupied by the first CSI report and the second CSI report is greater than the maximum CPU that the terminal can support, the terminal does not update the first CSI report or the second CSI report with lower priority.

[0258] In some embodiments, the first CSI report includes CSIs corresponding to at least two reference signal resources or at least two port groups of a reference signal resource.

[0259] In some embodiments, the port information corresponding to at least two reference signal resources or at least two port groups is configured independently.

[0260] In some embodiments, port information includes at least one of the following: the interval between ports, the number of ports, and the port location.

[0261] In some embodiments, at least two reference signal resources or at least two port groups correspond to different subarrays of an array.

[0262] In some embodiments, the first CSI report includes spatial basis vector (beam) information corresponding to at least two reference signal resources or at least two port groups, wherein the spatial basis vector information includes at least one of the following:

[0263] a) The first parameter is related to N1 and O1, where N1 is the number of antenna ports in the first dimension and O1 is the number of oversampled samples or beams in the first dimension; (or the first parameter is related to N1 and N2, where N2 is the number of antenna ports in the second dimension;)

[0264] b) The second parameter is related to N2 and O2, where N2 is the number of antenna ports in the second dimension and O2 is the number of oversampled samples or beams in the second dimension; (or the second parameter is related to O1 and O2).

[0272] In some embodiments, the CPU value of the first report is determined as follows:

[0273] The CPU value reported in the first report is:

[0274] O CPU =K s O CPUThis refers to the CPU value, where Ks is the number of CSI-RS resources contained in the CMR. For example, each subarray corresponds to one CSI-RS resource in the CMR, and the number of CSI-RS resources contained in the CMR is determined based on the CSI measurement configuration information. Alternatively, Ks can be the number of port groups contained in a reference signal resource. Or, Ks can be the number of CSI-RS resources with a first relationship. Here, the first relationship means that multiple reference signal resources correspond to the same first ID, which can be an association ID, link ID, TRP ID, panel ID, resource set ID, resource group ID, resource subset ID, pair ID, or array ID. In other words, all three of these are related to the CPU and the number of subarrays contained in an array.

[0275] The above applies to a single TRP. If there are multiple TRPs, it also depends on the number of TRPs, such as multiplying by the number of TRPs.

[0276] In some embodiments, the priority value is determined based on the following:

[0277] Referring to Formula 1 above, where

[0278] (1) For aperiodic CSI reports transmitted on PUSCH, y = 0. For semi-persistent CSI reports transmitted on PUSCH, y = 1. For semi-persistent CSI reports carried on PUCCH, y = 2. For periodic CSI reports carried on PUCCH, y = 3. This is unrelated to different CSI report types.

[0279] (2) For CSI reports carrying L1-RSRP or L1-SINR, k = 0. For CSI reports not carrying L1-RSRP or L1-SINR, k = 0. This depends on the specific CSI report type.

[0280] c is the serving cell index, N cells This is the value of a higher-level parameter (e.g., maxNrofServingCells). (cis the serving cell index and N) cells The value of the higher layer parameter `maxNrofServingCells` is unrelated to different CSI report types.

[0281] s is the report configuration identifier (reportConfigID), M s This is the value of a higher-level parameter (e.g., maxNrofCSI ReportConfigurations). (s is the reportConfigID and M s The value of the higher layer parameter `maxNrofCSI-ReportConfigurations` is unrelated to different CSI report types.

[0282] A higher priority value indicates a lower priority.
