[0122] 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.

[0123] 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, in sparse arrays, the antenna distribution is uneven, with some ports lacking antennas. Therefore, configuring the port information for a sparse array is a problem that needs to be solved.

[0124] Typical sparse arrays include the following:

[0125] (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.

[0126] 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, corresponding to positions 0d, 2d, and 4d, such as position "1" in Table 1; the second subarray is a 3-element subarray with a spacing of 3d, corresponding to positions 0d, 3d, and 6d, such as position "2" in Table 1.

[0127] Table 1

[0128] (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 and array degrees of freedom of the subarrays 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.

[0129] Table 2

[0130] Table 3

[0131] (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 the array elements in the redundant array.

[0132] Table 4

[0133] Therefore, this disclosure involves a terminal receiving first configuration information sent by a network device. This first configuration information is used to configure at least two sets of port information. Different sets of port information correspond to different reference signal resources, or different sets of port information correspond to different port groups of the same 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 can determine the port information corresponding to different subarrays of the sparse array through the first configuration information. This enables the application of sparse arrays in communication systems to save costs and energy consumption.

[0134] Figure 1d is a schematic diagram of a communication system architecture according to an embodiment of the present disclosure.

[0135] As shown in Figure 1d, the communication system 100 includes a terminal 101 and a network device 102.

[0136] 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.

[0140] 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.

[0145] 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:

[0146] In step S2101, network device 102 sends first configuration information to terminal 101.

[0147] In some embodiments, terminal 101 receives first configuration information sent by network device 102.

[0148] In some embodiments, the first configuration information is used to determine at least two sets of port information, wherein different sets of port information correspond to different reference signal resources, or different sets of port information correspond to different port groups of the same reference signal resource. For example, each reference signal resource corresponds to a set of port information, or each port group corresponding to the same reference signal resource corresponds to a set of port information.

[0149] In some embodiments, different reference signal resources correspond to different subarrays. Alternatively, different port groups of the same reference signal resource correspond to different subarrays. For example, each reference signal resource corresponds to one subarray, or each port group of the same reference signal resource corresponds to one subarray.

[0150] In some embodiments, different groups of port information may correspond to different subarrays. For example, one subarray may correspond to one group of port information.

[0151] In some embodiments, each group of port information includes at least one of the following: the position of the first port among N second ports; and the number of first ports. The first port is a port corresponding to a reference signal resource or port group, and is at least one of the N second ports, where N is a positive integer. The N second ports can be understood as N candidate ports of the array, and the first port corresponding to the reference signal resource or port group can be understood as a port corresponding to a subarray of the array. For example, the position of the first port among N second ports indicates which of the N second ports is the port corresponding to the subarray among the N ports of the array. For example, if N is 5 and the positions of the first ports are 1, 2, and 4, then the first, second, and fourth second ports are the first ports, and different subarrays form the array on the network device side.

[0152] It is understandable that different reference signal resources (or different port groups) may correspond to the same or different subarrays. The number of ports corresponding to different subarrays may be the same or different. That is, the number N of the second port in different groups may be the same or different.

[0153] For example, for the first set of port information, the number N of second ports can be N1, meaning the first set of port information includes at least one of the following: the position of the first port among the N1 second ports; and the number of first ports among the N1 second ports. For the second set of port information, the number N of second ports can be N2, meaning the second set of port information includes at least one of the following: the position of the first port among the N2 second ports; and the number of first ports among the N2 second ports. 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. Alternatively, 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.

[0154] It is understood that in this disclosure, N, N1, N2, etc., N represents the number of second ports corresponding to the subarray, N1 represents the number of second ports corresponding to the first subarray, and N2 represents the number of second ports corresponding to the second subarray. That is, when it is not distinguishing which subarray the molecular array is, this disclosure collectively refers to the number of its corresponding second ports as N. When it is not distinguishing which subarray the molecular array is, for ease of understanding, this disclosure refers to the number of its corresponding second ports as N plus a corresponding number. For example, the number of second ports corresponding to the first subarray is referred to as N1, and the number of second ports corresponding to the second subarray is referred to as N2. This disclosure does not provide examples for each case.

[0155] In some embodiments, each reference signal resource (or port group of the same reference signal resource) corresponds to a vector, which may include at least one of a spatial domain vector and a frequency domain vector.

[0156] In some embodiments, a spatial vector may also be referred to as a spatial basis vector, beam, or vector.

[0157] In some embodiments, the frequency domain vector may also be referred to as the frequency domain basis vector, or vector.

[0158] In step S2102, terminal 101 determines at least two sets of port information based on the first configuration information.

[0159] In some embodiments, the terminal may determine at least two sets of port information based on the first configuration information.

[0160] In some embodiments, the first configuration 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 specific examples, but is not limited to these.

[0161] For example, i can be 1, sum(Ni) = N1, and the first configuration information includes N1 bits. Bits with a 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 a bit is "1", the second port corresponding to that bit position can be used as the first port. If a bit is "0", the second port corresponding to that bit position is not used as the first port. Of course, the first value being "1" is just 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.

[0162] 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 configuration 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.

[0163] It is understandable that if i is 1, then the port information determined by the first configuration 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.

[0164] 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 configuration 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 configuration 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.

[0165] 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 configuration 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 configuration 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.

[0166] 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 configuration information, which will not be elaborated further in this disclosure.

[0167] In some embodiments, the first configuration 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 value of the bitmap indicates 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, that is, 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.

[0168] 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.

[0169] 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.

[0170] In some embodiments, the first configuration 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.

[0171] Optionally, the first configuration 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 port numbers corresponding to each subarray of the coprime array based on the configuration information.

[0172] 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 configuration information includes two sets of configuration information: 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 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 interval is the difference in the 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, take the first second port as the first first port of the first subarray. Then, after a gap of one empty position (or a gap of one second port), determine the second first port of the first subarray, and then after a gap of one empty position, determine the third first port of the first subarray. 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.

[0173] Optionally, the first configuration 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 is 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 configuration 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.

[0174] 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 configuration 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.

[0175] In some embodiments, the first configuration 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.

[0176] In some embodiments, the type includes an array type.

[0177] 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.

[0178] In some embodiments, the first type may be, for example, a coprime array.

[0179] For example, taking Table 1 as an example, the first configuration information may include: type 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 respectively, where d1 is half the wavelength, i.e., 0, 3, and 6 in the first row of Table 1 respectively.

[0180] 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.

[0181] In some embodiments, the second type may be, for example, a nested array.

[0182] For example, taking Table 3 as an example, the first configuration information may include: type is nested array, value is 6. 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 defaulted to the first second port, then the positions of the first ports in the first group 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 in the second group can be defaulted to 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 respectively, where d2 is half the wavelength, i.e., 3, 7, and 11 in the first row of Table 3.

[0183] In some embodiments, the first configuration 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.

[0184] In some embodiments, the CBSRs provide separate indications for different reference signal resources. Separate indications can be understood as each CBSR determining the number of first ports corresponding to a reference signal resource. For example, the first configuration 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.

[0185] In some embodiments, for different port groups of the same reference signal resource, the bitstring 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 configuration information includes a CBSR, in which the bitstring includes at least two parts, each part used to determine the number of a group of first ports.

[0186] In some embodiments, if the first configuration information includes a CBSR, the first configuration information may further 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 port among N second ports.

[0187] In some embodiments, the type includes an array type.

[0188] 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.

[0189] 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.

[0190] It is understood that the information of the first group of first ports in this disclosure refers to the first group of port information, such as the location and / or the number of the first group of first ports. Similarly, the information of the second group of first ports in this disclosure refers to the second group of port information, such as the location and / or the number of the second group of first ports.

[0191] It is understood that in the above embodiments of this disclosure, two subarrays are used as an example to determine two sets of port information, but the number of subarrays is not limited to this, and the number of sets of port information is not limited to this. For example, there can be three subarrays to determine three sets of port information. This disclosure will not provide examples of each of these.

[0192] In some embodiments, the name of the first configuration information is not limited, and it may be, for example, "first information".

[0193] In step S2103, network device 102 sends second configuration information to terminal 101.

[0194] In some embodiments, terminal 101 receives second configuration information sent by network device 102.

[0195] In some embodiments, the second configuration information is used to indicate the number of at least one set of first ports. For example, if the number of at least two sets of first ports determined by the first configuration information does not meet a preset rule, the network device can send the second configuration information to the terminal to indicate the number of at least one set of first ports, thereby ensuring that the number of at least two sets of first ports meets the preset rule.

[0196] In some embodiments, the second configuration information received by terminal 101 is sent by the network device when the number of at least two sets of first ports determined by the first configuration information does not meet a preset rule.

[0197] For example, if the first configuration information includes type and parameters, and the type is a nested array, and the number of first ports in the two determined groups of ports is M1 and M2 respectively, then the preset rules can be as shown in Table 2 above. As another example, if the first configuration information includes CBSR and type, and the type is a nested type, and the number of first ports in the two determined groups of ports is M1 and M2 respectively, then the preset rules can be as shown in Table 2 above. Of course, this disclosure only uses nested arrays as an example, but is not limited to this.

[0198] In some embodiments, the name of the second configuration information is not limited, and it may be, for example, "second information".

[0199] It is understood that step S2103 is optional. For example, if there is no preset rule between the number of at least two groups of first ports, step S2103 can be omitted. Or, if there is a preset rule between the number of at least two groups of first ports, and the number of at least two groups of first ports determined by the terminal based on the first configuration information satisfies the preset rule, step S2103 can be omitted. For another example, if there is a preset rule between the number of at least two groups of first ports, and the number of at least two groups of first ports determined by the terminal based on the first configuration information does not satisfy the preset rule, then step S2103 can be executed. That is, through the second configuration information, the number of at least one group of first ports can be configured so that the number of at least two groups of first ports satisfies the preset rule.

[0200] In step S2104, terminal 101 determines the order of at least two sets of first ports.

[0201] In some embodiments, the order of the first ports can be understood as the positional order of the antenna elements on the network device side. The order of the first ports is used to calculate the Channel Quality Indicator (CQI). For example, the channel states of different ports may be different, and the port order is used to accurately measure and calculate the CQI.

[0202] In some embodiments, the smaller the index of the first port, the higher its priority. The index can also be an identifier; that is, the smaller the identifier of the first port, the higher its priority. Higher priority can also be understood as its earlier position.

[0203] In some embodiments, the smaller the distance between the first port and a designated port among the N second ports, the higher the priority. Alternatively, the larger the distance between the first port and a designated port among the N second ports, the higher the priority. For example, the designated port can be the first second port among the N second ports, or the last second port, or any second port; this disclosure does not limit this. For example, for a coprime array, some ports of the second subarray are before the last port of the first subarray, and some are after the last port of the first subarray. That is, some ports of the second subarray have priority over the ports of the first subarray, and some do not. For nested arrays, all ports of the second subarray are after the last port of the first subarray, meaning that the port order of the second subarray is not priority over the port order of the first subarray.

[0250] Figure 5 is a schematic diagram illustrating a communication method according to an embodiment of the present disclosure. As shown in Figure 5, this embodiment of the present disclosure relates to a communication method, which includes:

[0251] In step S5101, network device 102 sends first configuration information to terminal 101.

[0252] In step S5102, terminal 101 receives the first configuration information.

[0253] 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.

[0254] This disclosure provides a communication method as follows:

[0255] In some embodiments, the terminal receives first configuration information and determines at least two pieces of first information based on the configuration information. The first information includes at least one of the number of ports and the port location. Different pieces of first information correspond to different reference signal resources or to different ports of the same reference signal resource.

[0256] In some embodiments, different reference signal resources correspond to different subarrays, or different ports (groups) correspond to different subarrays.

[0257] In some embodiments, the configuration information includes N bits, each indicating whether one of the N ports is active.

[0258] In some embodiments, a bit display of "1" indicates that the port is active, and "0" indicates that the port is inactive. This method is applicable to the three typical sparse arrays mentioned above, but for coprime arrays and nested arrays, this method requires a larger number of bits compared to the later methods.

[0259] In some embodiments, the configuration information includes N bits and the number of active ports P. The N bits are used to indicate the combination index of P ports selected from the total number of ports T. The total number of ports is the port index corresponding to the last port or index+1.

[0260] In some embodiments, for example, if the last port index is 31 and the first port index is 0, then the total number is 32, and the number of active ports is 17, then it indicates one of a variety of combinations of selecting 17 from 32.

[0261] In some embodiments, the configuration information includes at least one of the following: port start position, spacing between ports, and number of ports. This method is applicable to coprime arrays and nested arrays.

[0262] In some embodiments, for coprime arrays, the interval between ports corresponding to each subarray and the number of ports are indicated respectively. The port starting position of each subarray is the first port by default, so it does not need to be indicated.

[0263] In some embodiments, for nested sequences, the number of ports in the first subarray and the port spacing and number in the second subarray are indicated. This is because the first subarray starts at the first port by default, and the port spacing is d. The second subarray starts at a port position d after the last port of the first subarray.

[0264] In some embodiments, the configuration information includes a sparse array type indicator and corresponding parameter information for the array. This method is applicable to coprime arrays and nested arrays.

[0265] In some embodiments, parameter information corresponding to different subarrays is provided based on different types of sparse arrays. For example, for a coprime array, given the values ​​of P and Q, the number of ports in the first subarray is Q, the spacing is Pd, and the number of ports in the second subarray is 2P-1, with a spacing of Qd. For nested arrays, the total number of ports is given. For example, given the total number of ports M, the number of ports in the first and second subarrays, as well as the port spacing, are obtained depending on whether M is odd or even.

[0266] In some embodiments, the configuration information includes CBSR (codebook subset restriction) information.

[0267] In some embodiments, the traditional method is used, namely, the CBSR is used to implicitly indicate the number of ports.

[0268] Since a traditional array is a single array, a CBSR is assigned to each reference signal resource. Furthermore, in traditional methods, such as CJT, the number of ports corresponding to different reference signal resources is the same. The traditional indication method is as follows:

[0269] For example, the number of ports that can be configured for each traditional CSI-RS is shown in Table 5 below.

[0270] Table 5

[0271] Where (N1, N2) represent the number of ports in different dimensions, such as the horizontal and vertical dimensions. (O1, O2) represent the oversampling factor.

[0272] Traditionally, when considering a TRP transmission, the Rel-16 Type II codebook is configured with the following limitations. As you can see, n1 and n2 correspond to the number of ports in the first dimension and the number of ports in the second dimension, respectively. The bitsize corresponding to each CBSR is different for all different port numbers. The terminal can determine the values ​​of n1 and n2 based on the size of the bitstring. Our method described above is suitable for determining either the value of n1 or the value of n2.

[0273] In some embodiments, the CBSR is used to indicate the number of ports in a sparse array.

[0274] In some embodiments, if different subarrays correspond to different reference signal resources, then CBSRs are indicated for different reference signal resources, and the number of ports corresponding to different reference signal resources may be different.

[0275] In some embodiments, if different subarrays correspond to different ports of the reference signal resource, then a CBSR is indicated, and in the bitstring corresponding to a CBSR, some bits indicate the codebook limitation of the first subarray, and the other part indicates the codebook limitation of the second subarray; or it can also indicate two CBSRs, each CBSR corresponding to a port group.

[0276] In some embodiments, how the spacing between ports is determined: the configuration information also includes a sparse array type indication.

[0277] In some embodiments, for coprime arrays, the terminal can determine the spacing between ports by simply indicating the sparse array type and the number of ports.

[0278] In some embodiments, for nested arrays, it is only necessary to indicate the sparse array type, and the spacing between ports can also be determined based on the number of ports.

[0279] In some embodiments, if the number of ports in the two subarrays of the nested array is not sufficient to meet the rules in Table 2, the number of ports in the second subarray may be additionally indicated.

For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD).

For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules.
