[0026] FIG. 2 is a flowchart of an information reporting method provided by an exemplary embodiment of the present application, which is illustratively applicable to the terminal and network device shown in FIG. 1, and the method includes at least some of the following contents:

[0027] In step 201, a terminal transmits channel state information to a network device, where the channel state information indicates phase information and / or amplitude information of at least two access network devices.

[0028] In an embodiment of the present application, a network device arranges at least one access network device to serve a terminal, and each access network device has a corresponding phase and amplitude, and the terminal can indicate the phase information and / or amplitude information of at least two access network devices by sending channel state information.

[0029] Here, the terminal obtains channel state information measured based on at least one resource by performing measurements based on CSI-RS (Channel State Information-Reference Signal) and / or SSB (Synchronization Signal and PBCH Block) transmitted from the network device, and indicates the phase information and / or amplitude information of the obtained at least two access network devices according to the channel state information, and further notifies the phase information and / or amplitude information of the at least two access network devices in the network device.

[0030] In step 202, the network device receives channel state information transmitted from the terminal.

[0031] In an embodiment of the present application, the network device can determine the phase information and / or amplitude information of at least two access network devices reported by the terminal according to the received channel state information, and ensure that the network device knows the phase information and / or amplitude information of each access network device among the at least two access network devices.

[0032] In some embodiments, each access network device has an access network device identifier, and the identifier corresponding to each access network device is indicated by at least one of a resource index, a resource subset index, a resource set index, a control resource set pool index, an antenna port index, a TRP index, a TP index, an RRH index, and an antenna panel index.

[0033] It should be noted that in the embodiments of the present application, the antenna port is only described as an example, and in other embodiments, the antenna port and the CSI-RS (Channel State Information Reference Signal) port or the CSI-RS antenna port can be equivalently replaced, and are not limited to the embodiments of the present application.

[0034] It should be noted that the steps performed by the terminal in the embodiments of the present application can be implemented separately to form new embodiments, and the steps performed by the network device can be implemented separately to form new embodiments.

[0035] An embodiment of the present application provides an information reporting method, in which a terminal reports channel state information to a network device, thereby indicating phase information and / or amplitude information of each access network device among at least two access network devices, and further ensuring that the network device determines the phase and / or amplitude of each access network device, which not only improves transmission performance but also saves signaling overhead.

[0036] Optionally, based on the embodiment shown in FIG. 2, the phase of the access network device is indicated by two types of phase coefficients.

[0037] In some embodiments, the phase information includes a first type phase coefficient and a second type phase coefficient, where the first type phase coefficient indicates a phase coefficient corresponding to each access network device of the at least two access network devices, and the second type phase coefficient indicates a phase coefficient corresponding to each element within each access network device, and the first type phase coefficient and the second type phase coefficient are used to determine a phase of each element within each access network device.

[0038] In the embodiments of the present application, the first type of phase coefficient is designated as a dimension of the access network device, i.e., a phase coefficient corresponding to each access network device, and may be understood as a common phase coefficient of each element of the access network device. The second type of phase coefficient is designated as a dimension of the element of the access network device, i.e., a phase coefficient corresponding to each element, and may be understood as a phase coefficient corresponding to each element individually.

[0039] Here, the first type phase coefficient and the second type phase coefficient included in the phase information indicate the phase corresponding to each element in the access network device.

[0040] In some embodiments, the product of the first type phase coefficient and the second type phase coefficient is the phase corresponding to each element in the access network device.

[0041] Wherein, the first type phase coefficient indicates a common phase coefficient of the elements in each access network device, and the second type phase coefficient indicates a phase coefficient individually corresponding to each element, and to determine a phase corresponding to each element in the access network device, the product of the first type phase coefficient and the second type phase coefficient is determined as the phase corresponding to each element in the access network device.

[0042] In some other embodiments, the sum of the first type phase coefficient and the second type phase coefficient is the phase corresponding to each element in the access network device.

[0043] Here, the first type of phase coefficient indicates a common phase coefficient of elements in each access network device, and the second type of phase coefficient is a phase coefficient corresponding to each element individually, and to determine the phase corresponding to each element in the access network device, the sum of the first type of phase coefficient and the second type of phase coefficient is determined as the phase corresponding to each element in the access network device.

[0044] In some embodiments, the element (1) an antenna port; (2) a beam; (3) Wideband and (4) subbands; (5) a frequency domain unit; (6) Time domain unit, and at least one or more combinations of.

[0045] It should be noted that the embodiment of the present application only takes the second type of phase coefficient as an example, and in another embodiment, the second type of phase coefficient is distinguished according to the element.

[0046] Optionally, the interval between the second type phase coefficients corresponding to two adjacent elements in each access network device of the at least two access network devices is the first interval, and / or the interval between the second type phase coefficients corresponding to two adjacent elements between two adjacent access network devices is the first interval.

[0047] In an embodiment of the present application, for each access network device among the at least two access network devices, the multiple elements included in each access network device are sorted in order, and the interval between the second type phase coefficients corresponding to two adjacent elements is the first interval.

[0048] Furthermore, the at least two access network devices further include two adjacent access network devices, and the interval between the second-type phase coefficients corresponding to two adjacent elements between the two adjacent access network devices is the first interval. For the two adjacent access network devices, it may be understood that the interval between the second-type phase coefficient corresponding to the last element located in the previous access network device and the second-type phase coefficient corresponding to the first element located in the next access network device is the first interval.

[0049] For example, the target includes two access network devices, namely, access network device 1 and access network device 2, where access network device 1 includes element 1, element 2, and element 3, and access network device 2 includes element 4, element 5, and element 6, i.e., the interval between the second type phase coefficient corresponding to element 3 in access network device 1 and the second type phase coefficient corresponding to element 4 in access network device 2 is the first interval.

[0050] In some embodiments, the first interval is related to the number of elements in the access network device, for example, 2pi / N1, where N1 is directly the number of elements in the access network device, or is half or related to the number of elements in the access network device.

[0051] For example, the difference between the second-type phase coefficients corresponding to two adjacently numbered antenna ports in one access network device is 2pi / N1, where N1 is related to the number of antenna ports in the access network device, and N1 is directly the number of antenna ports in the access network device, or is half the number of antenna ports in the access network device, or is related to the number of antenna ports.

[0053] Additionally, the phase information in the embodiments of the present application may be at least one of a wideband phase coefficient and a narrowband phase coefficient.

[0054] Here, wideband refers to the entire bandwidth, i.e., wideband. Narrowband refers to dividing the entire bandwidth into multiple subbands. When the bandwidth is 24-72 PRBs (Physical Resource Blocks), the subband size is 4 or 8 PRBs; when the bandwidth is 73-144 PRBs, the subband size is 8 or 16 PRBs; and when the bandwidth is 145-275 PRBs, the subband size is 16 or 32 PRBs.

[0055] It should be noted that the above embodiment only exemplifies that the phase information includes a first type phase coefficient and a second type phase coefficient, in another embodiment, the phase information can further include phases of different elements in at least two access network devices, and the interval between the phases corresponding to any two adjacent elements in the at least two access network devices is a target interval.

[0056] In the embodiments of the present application, the phases included in the phase information are phases corresponding to different elements individually within each access network device, so that the corresponding phases for any element within each access network device can be determined, there is an interval between the phases corresponding to each element, and the interval between the phases corresponding to any two adjacent elements is a target interval, that is, the phases corresponding to different elements within the access network device are distributed at equal intervals.

[0057] Optionally, the target spacing is related to the number of elements in the access network device, for example, 2pi / N1, where N1 is directly the number of elements in the access network device, or is half or related to the number of elements in the access network device.

[0058] The method provided by the embodiments of the present application can indicate the phase of each element in each access network device by the phase of each element included in the phase information, which not only improves transmission performance but also saves signaling overhead.

[0060] In some embodiments, the amplitude information includes a first type of amplitude coefficient and a second type of amplitude coefficient, where the first type of amplitude coefficient indicates an amplitude coefficient corresponding to each access network device of the at least two access network devices, the second type of amplitude coefficient indicates an amplitude coefficient corresponding to each element within each access network device, and the first type of amplitude coefficient and the second type of amplitude coefficient are used to determine the amplitude of each element within each access network device.

[0061] In the embodiments of the present application, the first type of amplitude coefficients are designated with respect to the access network device as a dimension, i.e., amplitude coefficients corresponding to each access network device, and may be understood as amplitude coefficients common to each element of the access network device, while the second type of amplitude coefficients are designated with respect to the element of the access network device as a dimension, i.e., amplitude coefficients corresponding to each element, and may be understood as amplitude coefficients corresponding to each element individually.

[0062] Here, the amplitude corresponding to each element in the access network device is indicated by the first type amplitude coefficient and the second type amplitude coefficient included in the amplitude information.

[0063] In some embodiments, the product of the first type amplitude coefficient and the second type amplitude coefficient is an amplitude corresponding to each element in the access network device.

[0064] Here, the first type of amplitude coefficient indicates a common amplitude coefficient of elements within each access network device, and the second type of amplitude coefficient is an amplitude coefficient corresponding to each element individually, and to determine the amplitude corresponding to each element within the access network device, the product of the first type of amplitude coefficient and the second type of amplitude coefficient is determined as the amplitude corresponding to each element within the access network device.

[0065] In some other embodiments, the sum of the first type amplitude coefficient and the second type amplitude coefficient is the amplitude corresponding to each element in the access network device.

[0066] Here, the first type of amplitude coefficient indicates a common amplitude coefficient of the elements in each access network device, and the second type of amplitude coefficient is an amplitude coefficient corresponding to each element individually, and to determine the amplitude corresponding to each element in the access network device, the sum of the first type of amplitude coefficient and the second type of amplitude coefficient is determined as the amplitude corresponding to each element in the access network device.

[0067] In some embodiments, the element (1) an antenna port; (2) a beam; (3) Wideband and (4) subbands; (5) a frequency domain unit; (6) Time domain unit, and at least one or more combinations of.

[0068] It should be noted that the embodiment of the present application only takes the second type of amplitude coefficient as an example, and in another embodiment, the second type of amplitude coefficient is distinguished according to the element.

[0069] Optionally, the spacing between the second type amplitude coefficients corresponding to two adjacent elements within each access network device of the at least two access network devices is the second spacing, and / or the spacing between the second type amplitude coefficients corresponding to two adjacent elements between two adjacent access network devices is the second spacing.

[0070] In an embodiment of the present application, for each access network device among the at least two access network devices, the multiple elements included in each access network device are sorted in order, and the interval between the second type amplitude coefficients corresponding to two adjacent elements is a second interval.

[0071] Furthermore, the at least two access network devices further include two adjacent access network devices, and the interval between the second-type amplitude coefficients corresponding to two adjacent elements between the two adjacent access network devices is the second interval. For two adjacent access network devices, it may be understood that the interval between the second-type amplitude coefficient corresponding to the last element located in the previous access network device and the second-type amplitude coefficient corresponding to the first element located in the next access network device is the second interval.

[0072] For example, the target includes two access network devices, access network device 1 and access network device 2, respectively, where access network device 1 includes element 1, element 2, and element 3, and access network device 2 includes element 4, element 5, and element 6, i.e., the interval between the second type amplitude coefficient corresponding to element 3 in access network device 1 and the second type amplitude coefficient corresponding to element 4 in access network device 2 is the second interval.

[0073] In some embodiments, the second interval is related to the number of elements in the access network device, for example, the second interval is total amplitude / N1, where N1 is directly the number of elements in the access network device, or is half or related to the number of elements in the access network device.

[0074] For example, the difference between the second-type phase coefficients corresponding to two adjacently numbered antenna ports in one access network device is total amplitude / N1, where N1 is related to the number of antenna ports in the access network device, and N1 is directly the number of antenna ports in the access network device, or is half the number of antenna ports in the access network device or related to the number of antenna ports.

[0076] It should be noted that the above embodiment only exemplifies that the amplitude information includes a first type amplitude coefficient and a second type amplitude coefficient, and in another embodiment, the amplitude information can further include amplitudes of different elements in at least two access network devices.

[0077] In the embodiment of the present application, the amplitudes included in the amplitude information are amplitudes corresponding to different elements individually within each access network device, so that the corresponding amplitudes can be determined for the average elements within each access network device.

[0078] The method provided by the embodiments of the present application can indicate the amplitude of each element in each access network device by the amplitude of each element included in the amplitude information, which not only improves transmission performance but also saves signaling overhead.
