[0130] In some embodiments, the first configuration information is used to indicate a first coefficient and a second coefficient corresponding to each CSI-RS resource in a plurality of CSI-RS resources.

The network device only supports the number of CSI-RS ports included in a CSI-RS resource of 1, 2, 4, 8, 12, 16, 24, and 32.

[0143] In the embodiment of the present disclosure, the network device sends first configuration information to the terminal, where the first configuration information is used to indicate first coefficients and corresponding second coefficients corresponding to a plurality of CSI-RS resources.

[0144] In an embodiment of the present disclosure, a network device is supported to configure a first coefficient and a second coefficient corresponding to each of a plurality of CSI-RS resources for a terminal, and determine the number of CSI-RS ports based on the first coefficient and the second coefficient corresponding to each of a plurality of CSI-RS resources.

[0145] In some embodiments, the network device sends second configuration information to the terminal, wherein the second configuration information is used to indicate multiple CSI-RS resource sets, the multiple CSI-RS resource sets include multiple CSI-RS resources, and the CSI-RS resources belonging to the same CSI-RS resource set belong to the same resource group.

[0146] In an embodiment of the present disclosure, a network device may send second configuration information to a terminal, where the second configuration information is used to indicate multiple CSI-RS resource sets, where the multiple CSI-RS resource sets include multiple CSI-RS resources, and where the CSI-RS resources belonging to the same CSI-RS resource set belong to the same resource group.

[0147] In some embodiments, the network device sends third configuration information to the terminal, where the third configuration information is used to indicate a CSI-RS resource set, and the CSI-RS resource set includes multiple CSI-RS resources.

[0148] In an embodiment of the present disclosure, a network device may send third configuration information to a terminal, where the third configuration information is used to indicate a CSI-RS resource set, where the CSI-RS resource set includes multiple CSI-RS resources. In this case, the network device sends first configuration information to the terminal, where the first configuration information is used to indicate first coefficients and second coefficients corresponding to the multiple CSI-RS resources.

[0149] S202: The terminal determines the number of CSI-RS ports according to the first coefficient and the second coefficient.

[0150] In the disclosed embodiment, a terminal receives first configuration information sent by a network device, where the first configuration information indicates first coefficients and second coefficients corresponding to multiple CSI-RS resources. Thus, the terminal can determine the number of CSI-RS ports based on the first coefficients and second coefficients corresponding to the multiple CSI-RS resources.

[0151] It can be understood that the number of CSI-RS ports included in a CSI-RS resource is twice the product of the first coefficient and the second coefficient corresponding to the CSI-RS resource configured by the network device. The number of CSI-RS ports included in a CSI-RS resource configured by the network device only supports 1, 2, 4, 8, 12, 16, 24 and 32. In the embodiment of the present disclosure, the network device configures the first coefficient and the second coefficient corresponding to each of the multiple CSI-RS resources for the terminal, and the terminal can determine the number of CSI-RS ports based on the first coefficient and the second coefficient corresponding to each of the multiple CSI-RS resources, wherein the number of CSI-RS ports can be greater than 32. Thus, the configuration of a larger number of CSI-RS ports can be achieved to support channel measurement of a larger number of CSI-RS ports and improve the performance of the communication system.

[0152] In some embodiments, the first coefficient is 2 and the second coefficient is 1; or the first coefficient is 2 and the second coefficient is 2; or the first coefficient is 4 and the second coefficient is 1; or the first coefficient is 3 and the second coefficient is 2; or the first coefficient is 6 and the second coefficient is 1; or the first coefficient is 4 and the second coefficient is 2; or the first coefficient is 8 and the second coefficient is 1; or the first coefficient is 4 and the second coefficient is 3; or the first coefficient is 6 and the second coefficient is 2; or the first coefficient is 12 and the second coefficient is 1; or the first coefficient is 4 and the second coefficient is 4; or the first coefficient is 8 and the second coefficient is 2; or the first coefficient is 16 and the second coefficient is 1.

[0153] In some embodiments, the number of CSI-RS ports is 48; or the number of CSI-RS ports is 64; or the number of CSI-RS ports is 72; or the number of CSI-RS ports is 96; or the number of CSI-RS ports is 128.

[0154] In some embodiments, the terminal determines the number of CSI-RS ports based on the first coefficient and the second coefficient, including: determining the number of CSI-RS sub-ports of each CSI-RS resource based on the first coefficient and the second coefficient corresponding to each CSI-RS resource in multiple CSI-RS resources, and then determining the number of CSI-RS ports based on the number of CSI-RS sub-ports of each CSI-RS resource.

[0155] In some embodiments, the terminal determines the number of CSI-RS ports based on the first coefficient and the second coefficient, including: determining the first parameter and the second parameter based on the first coefficient and the second coefficient; and determining the number of CSI-RS ports as twice the product of the first parameter and the second parameter based on the first parameter and the second parameter.

[0156] In an embodiment of the present disclosure, when determining the first coefficient and the second coefficient corresponding to each CSI-RS resource in a plurality of CSI-RS resources, the terminal can determine the first parameter and the second parameter based on the first coefficient and the second coefficient, and then determine the number of CSI-RS ports as twice the product of the first parameter and the second parameter based on the first parameter and the second parameter.

[0157] In some embodiments, the first parameter is the number of ports in the horizontal dimension, and the second parameter is the number of ports in the vertical dimension.

[0158] In some embodiments, the first parameter is the number of ports in a horizontal dimension in one polarization direction, and the second parameter is the number of ports in a vertical dimension in one polarization direction.

[0159] It can be understood that the antenna port is dual-polarized, the number of ports in the horizontal dimension in one polarization direction is the first parameter, the number of ports in the vertical dimension is the second parameter, and the number of antenna ports in different polarization directions is equal. Therefore, the number of antenna ports can be twice the product of the first parameter and the second parameter.

[0160] Exemplarily, the configuration of a number of CSI-RS ports greater than 32 is jointly determined by multiple CSI-RS resources configured by the network device. When the number of CSI-RS ports is greater than 32, such as the number of CSI-RS ports = 48, 64, 72, 96 and 128, the corresponding first parameter N1 and the second parameter N2 may be combined as shown in Table 2 below.

[0164] In an embodiment of the present disclosure, multiple CSI-RS resources configured by a network device belong to two resource groups, and different CSI-RS resources in the same resource group correspond to the same first coefficient and the same second coefficient, respectively, that is, the first coefficients of different CSI-RS resources in the same resource group are the same, and the second coefficients of different CSI-RS resources in the same resource group are also the same. When the products of the first coefficient and the second coefficient corresponding to the CSI-RS resources in different resource groups are not equal, if the first coefficient corresponding to the CSI-RS resource of the first resource group of the two resource groups is equal to the first coefficient corresponding to the CSI-RS resource of the second resource group, the terminal can determine that the first parameter is equal to the first coefficient, and the second parameter is the sum of the second coefficients corresponding to all CSI-RS resources of the first resource group plus the sum of the second coefficients corresponding to all CSI-RS resources of the second resource group.

[0165] For example, the network configures I CSI-RS resources for the terminal, where I is an integer greater than 1, and the I CSI-RS resources belong to two resource groups, wherein the first coefficient N corresponding to the L resources of the first resource group is 1,i are equal and the corresponding second coefficient N 2,i are all equal, i∈{0,…,L-1}, the first coefficient N′ corresponding to M=IL resources in the second resource group 1,j are equal and the corresponding second coefficient N′ 2,j are equal, j∈{0,…,M-1}, if N 1,i =N′ 1,j , the terminal can determine the first parameter N1 and the second parameter N2: N1 = N 1,i =N′ 1,j ,

[0166] In some embodiments, the terminal determines the first parameter and the second parameter based on the first coefficient and the second coefficient, including: if multiple CSI-RS resources belong to two resource groups, different CSI-RS resources in the same resource group correspond to the same first coefficient and the same second coefficient, respectively, the products of the first coefficient and the second coefficient corresponding to the CSI-RS resources in different resource groups are not equal, the second coefficient corresponding to the CSI-RS resources of the first resource group of the two resource groups is equal to the second coefficient corresponding to the CSI-RS resources of the second resource group, the first parameter is determined to be the sum of the first coefficients corresponding to all CSI-RS resources of the first resource group plus the sum of the first coefficients corresponding to all CSI-RS resources of the second resource group, and the second parameter is equal to the second coefficient.

The first resource group has L=2 CSI-RS resources corresponding to the first coefficient N. 1,i are equal and the corresponding second coefficient N 2,i are equal, where N 1,i =8 and N 2,i =2, i∈{0,1}, and the first coefficient N′ corresponding to the CSI-RS resource of the second resource group 1,j are equal and the corresponding second coefficient N′ 2,j are equal, where N′ 1,j =4 and N′ 2,j =2,j∈{0,1}. Since N2,i =N′ 2,j =2, the terminal can determine the first parameter N1 and the second parameter N2: N2=N 2,i =N′ 2,j =2, then the terminal can determine the number of CSI-RS ports as twice the product of the first parameter and the second parameter.

When the products of the first coefficients and the second coefficients corresponding to the CSI-RS resources in different resource groups are not equal, if the first coefficient corresponding to the CSI-RS resources of the first resource group in the two resource groups is smaller than the first coefficient corresponding to the CSI-RS resources of the second resource group, and the sum of the second coefficients corresponding to all CSI-RS resources of the first resource group is equal to the second coefficient corresponding to the CSI-RS resources of the second resource group, then the terminal can determine that the first parameter is the sum of the first coefficients corresponding to the CSI-RS resources of the second resource group plus the first coefficient corresponding to the CSI-RS resources of the first resource group, and the second parameter is the second coefficient corresponding to the CSI-RS resources of the second resource group.
