[0081] The present disclosure will be described in further detail below with reference to the accompanying drawings and embodiments.

[0082] In the CSI basic framework of the relevant technology, the CSI reporting setting (which can be expressed as Reporting Setting or Report Setting in English) corresponds to the information element (IE) named CSI reporting configuration (CSI-ReportConfig) in the radio resource control (RRC) signaling. CSI-ReportConfig is used to indicate the relevant configuration of CSI reporting, which may specifically include reporting time domain characteristics, frequency domain bandwidth granularity, reporting quantity (reportQuantity), time domain restrictions, codebook settings and other configurations. Among them, the time domain characteristics of CSI-ReportConfig may include periodicity, semi-continuous and non-periodic. In addition, there is at least one CSI resource configuration identifier (CSI-ResourceConfigId) in the CSI-ReportConfig. The CSI resource corresponding to the identifier can be used for channel measurement and reporting, or the CSI-ResourceConfigId for interference measurement can also be configured.

[0083] The CSI resource setting (which can be expressed as Resource Setting in English) corresponds to the IE named CSI resource configuration (CSI-ResourceConfig) in RRC signaling. CSI-ResourceConfig is used to determine the resources used for CSI measurement. The resource types (which can be expressed as resourceType in English) of these resources can include periodic, semi-persistent, and aperiodic. Among them, each resource setting can contain at least one resource set (which can be expressed as Resource Set in English, which can be abbreviated as Set). For periodic resources and semi-persistent resources, there is only one CSI-RS resource set in a resource configuration (ResourceConfig); and a ResourceConfig for aperiodic resources can contain up to 64 CSI-RS resource sets.

[0084] In the CSI-RS resource (CSI-RS-Resource) configuration, for periodic / semi-persistent resource (Resource) level configuration, the period and offset (offset) can be configured in the NZP CSI-RS resource periodicity and offset (PeriodicityAndOffset) configuration. All resources in a resource set have the same period, but different offsets. For aperiodic resources, the offset can be configured at the resource set level in RRC. For example, the aperiodic triggering offset AperiodicTriggeringOffset = [0, 1, 2, 3, 4, 5, 6] can be configured in the NZP CSI-RS resource set (NZP-CSI-RS-ResourceSet) domain, corresponding to time slots = [0, 1, 2, 3, 4, 16, 24], respectively. The specific number of aperiodic triggering offsets can be set as required, for example, 32. If all CSI aperiodic trigger state (CSI-AperiodicTriggerState) transmission configuration indication (TCI) states do not have Quasi-CoLocation-Type D (QCL-Type D), the default offset is 0 slots (i.e., offset = 0slot). In addition, the offset of the CSI-IM resource is the same as the offset of the NZP CSI-RS resource for channel measurement (NZP CSI-RS-CM) associated with the resource, and the offset of the NZP CSI-RS resource for interference measurement is also configured to be the same as the offset of the NZP CSI-RS resource for channel measurement associated with the resource.

[0085] Regarding the correspondence between CSI-ReportConfig and CSI-ResourceConfig, an aperiodic CSI-ResourceConfig can be associated with a periodic / semi-persistent / aperiodic CSI-ResourceConfig. When a CSI-ResourceConfig is associated with one CSI-ResourceConfig, the CSI-ResourceConfig is used only for Layer 1 Reference Channel Received Power (L1-RSRP) measurement. When a CSI-ReportConfig is associated with two CSI-ResourceConfigs, the first CSI-ResourceConfig is used for channel measurement, and the second CSI-ResourceConfig is used for interference measurement. The resources in the CSI-ResourceConfig include CSI-IM resources or NZP CSI-RS resources. When a CSI-ResourceConfig is associated with three CSI-ResourceConfigs, the first CSI-ResourceConfig is used for channel measurement, the second CSI-ResourceConfig is used for CSI-IM interference measurement, and the third CSI-ResourceConfig is used for NZP CSI-RS interference measurement. A periodic / semi-persistent CSI-ReportConfig can be associated with a periodic / semi-persistent CSI-ResourceConfig, where when a CSI-ReportConfig is associated with one CSI-ResourceConfig, the CSI-ResourceConfig is used only for L1-RSRP measurement; when a CSI-ReportConfig is associated with two CSI-ResourceConfigs, the first CSI-ResourceConfig is used for channel measurement, and the second CSI-ResourceConfig is used for CSI-IM interference measurement. It should be noted that the time domain characteristics of all CSI resource settings under a CSI report setting are consistent, the number of ports (which can be expressed as port in English) for each resource in the NZP CSI-RS resource set used for channel measurement should be the same, the number of resources in the CSI-IM resource set is the same as the number of resources in the NZP CSI-RS resource set used for channel measurement, and they correspond one to one in sequence to calculate the CQI.In addition, when an NZP CSI-RS is used for interference measurement, only one resource can be configured in the corresponding NZP CSI-RS resource set for channel measurement for channel measurement; the number of ports for each resource in the NZP CSI-RS resource set for interference measurement can be different, but the total number of ports for all resources cannot exceed 18; each port of the NZP CSI-RS for interference measurement corresponds to an interference transmission layer.

[0086] In the related art, there are three types of CSI reports: periodic reporting, semi-continuous reporting and non-periodic reporting. Among them, when the terminal adopts periodic reporting, the network side defines the period and time slot offset through the CSI report periodicity and offset (which can be expressed as CSI-ReportPeriodicityAndOffset in English) in CSI-ReportConfig. When the terminal adopts semi-continuous reporting, if the terminal uses the physical uplink control channel (Physical Uplink Control CHannel, PUCCH) for reporting, the network side defines the period and time slot offset through the CSI report periodicity and offset, which is the same as periodic reporting; and the network side can activate / deactivate through the Media Access Control (Media Access Control, MAC) control element (Control Element, CE) (that is, through the Physical Downlink Shared CHannel (Physical Downlink Shared CHannel, PDSCH)); if the time slot in which the terminal sends the acknowledgment response (Hybrid Automatic Repeat request-ACKnowledgement, HARQ-ACK) corresponding to the PDSCH is n, the corresponding configuration in the time slot Take effect. When the terminal adopts semi-continuous reporting, if the terminal uses the physical uplink shared channel (PUSCH) for reporting, the network side indicates the reporting period through the report slot configuration (expressed as reportSlotConfig in English), indicates the list of candidate time slot offset values ​​through the report time slot offset list (expressed as reportSlotOffsetList in English), activates through the CSI request (expressed as CSI request in English) in the downlink control information 0_1 (DCI0_1, Downlink Control Information 0_1), and determines a specific time slot offset according to the time domain resource assignment (expressed as Time domain resource assignment in English) in the downlink control information (DCI). When the terminal adopts aperiodic reporting, it can specifically use PUSCH for reporting. The network side indicates the list of candidate time slot offset values ​​through the report time slot offset list, triggers through the CSI request in DCI0_1, and determines a specific time slot offset according to the indication of the time domain resource allocation in the DCI. In addition, the relationship between the CSI reporting configuration and the resource type is shown in Table 1.

[0087] Table 1

[0088] In related technologies, when a terminal performs channel measurement, it needs to perform PDSCH demodulation. Specifically, in a multi-user (MU) system, the received signal of the terminal can be expressed by the following formula: y = H s P s x s +H s P c x c +∑ k H k P k x k +n (1)

[0089] Among them, H s P s x s Represents the useful signal, H s represents the channel corresponding to the s-th stream data of the serving cell and the user (ie, the terminal), P s represents the precoding matrix corresponding to the serving cell and the user's s-th stream data, x s Indicates the sending signal corresponding to the s-th stream data of the serving cell and the user; H s P cx c represents the inter-stream interference, P c represents the precoding matrix corresponding to the c-th stream data of the serving cell, x c Indicates the transmission signal corresponding to the c-th stream data of the serving cell; ∑ k H k P k x k represents the inter-cell interference, H k represents the channel between neighboring cell k and the user, P k represents the precoding matrix of neighboring cell k, x k represents the transmitted signal of neighboring cell k; n represents noise.

[0090] To restore the useful signal while suppressing interference and noise, the receiver at the receiving end (i.e., the terminal) can use the minimum mean square error (MMSE) algorithm to calculate the equalization matrix w. When the network side does not configure the terminal with NZP CSI-RS for multi-user multiple-input multiple-output (MU-MIMO) inter-stream interference measurement, and the terminal only obtains the inter-stream interference power through CSI-IM, the terminal can obtain the equalization matrix w1 using the following formula:

[0091] in, Represents the power of noise and all interference (which may include inter-stream interference and inter-cell interference for MU systems).

[0092] When the network side configures the NZP CSI-RS for MU-MIMO inter-stream interference measurement for the terminal, the terminal can obtain the equalization matrix w2 through the following formula:

[0093] in, Indicates the power of noise and inter-cell interference.

[0094] Based on formula (1), formula (2), and formula (3), the signal to interference plus noise ratio (SINR) for a specific stream i can be expressed by the following formula:

[0095] Among them, Interf represents interference and Noise represents noise.

[0096] As can be seen from the above description, in the CSI basic framework of the related technology, in order for the terminal to measure the SINR of the channel, the network side usually needs to configure CSI-RS for channel measurement and CSI-IM for measuring neighboring cell interference, and may also be additionally configured with NZP CSI-RS for measuring MU-MIMO interference in the local cell; the terminal measures the SINR based on these reference signals (RS), and quantizes the measured SINR into CQI and reports it to the network side.

[0097] In a time division duplex (TDD) system, considering the presence of channel reciprocity, the network can estimate the downlink channel using the sounding reference signal (SRS). Combined with the CQI fed back by the terminal, the network can infer the interference and noise received by the terminal. Specifically, the network can estimate the interference and noise received by the terminal using the following formula:

[0098] Among them, I Interference Indicates interference, Noise indicates noise; S RS Indicates the downlink channel estimated by the network side through SRS; CQI is the channel measurement result reported by the terminal to the network side.

[0099] However, as shown in Table 2, wideband CQI only occupies 4 bits; as shown in Table 3 (mapping sub-band differential CQI value to offset level), narrowband CQI only occupies 2 bits. Therefore, CQI is subject to certain quantization error loss. Correspondingly, the terminal interference and noise derived by the network based on CQI also suffer from quantization error loss. In other words, the network performs terminal interference measurement based on the channel measurement results (i.e., CQI) reported by the terminal, and the estimated interference amount is subject to quantization error loss. Therefore, the accuracy of terminal interference measurement needs to be improved urgently.

[0100] Table 2

[0101] Table 3

[0102] In addition, from the above formulas (4) and (5), it can be seen that the terminal interference amount derived by the network side based on CQI is a scalar, that is, an interference power. Such interference estimation is relatively rough, which is not conducive to the terminal's interference suppression of neighboring cells on the one hand, and is not conducive to the network side's subsequent accurate and efficient downlink precoding and resource scheduling on the other hand.

[0103] Based on this, in various embodiments of the present disclosure, the network side sends configuration information related to interference measurement to the terminal, specifically including at least one of information for indicating a reported amount (the reported amount at least includes an interference amount), information for indicating at least one first resource set (at least one first resource set is used for interference measurement), and information for indicating at least one second resource set (at least one second resource set is used for interference measurement). In this way, subsequent terminals can directly use the configuration information related to interference measurement to perform interference measurement to obtain the interference amount that needs to be reported, and directly report the obtained interference amount to the network side, that is, the network side does not need to estimate the interference amount based on the channel measurement result reported by the terminal, but can directly obtain the interference amount measured and reported by the terminal, thereby achieving decoupling of the terminal channel measurement and the terminal interference measurement. Moreover, on the one hand, since the network side separately configures a resource set for interference measurement for the terminal, and the network side does not need to estimate the amount of interference based on the channel measurement results reported by the terminal, the CSI-RS overhead for channel measurement on the network side can be reduced; on the other hand, since the network side does not need to estimate the amount of interference based on the channel measurement results reported by the terminal but can directly obtain the amount of interference measured and reported by the terminal, the accuracy of the terminal interference measurement can be improved, helping the network side to subsequently perform accurate and efficient downlink precoding and resource scheduling, while reducing the computational complexity of the terminal.

[0104] In addition, in various embodiments of the present disclosure, taking into account that the interference received by the terminal on different ports is spatially selective, that is, the degree of interference received by the terminal on different ports is different, the terminal can report the amount of interference in the form of an interference coherence matrix (that is, a quantization matrix), which can help the terminal to suppress neighboring cell interference during PDSCH demodulation on the one hand; on the other hand, by reporting the matrix to the network side, it can help the network side to perform more accurate and efficient downlink precoding and resource scheduling based on the demodulation situation of the terminal.

[0105] Specifically, an embodiment of the present disclosure provides an information transmission method, applied to a terminal, including:

[0106] Receive configuration information sent by the network side, where the configuration information includes at least one of the following:

[0107] First information, where the first information is used to indicate a reported amount, where the reported amount at least includes an interference amount;

[0108] second information, where the second information is used to indicate at least one first resource set, where the at least one first resource set is used for interference measurement, and each first resource set includes at least one CSI-IM resource;

[0109] The third information is used to indicate at least one second resource set, where the at least one second resource set is used for interference measurement, and each second resource set includes at least one NZP CSI-RS resource.

[0110] In actual application, the terminal may also be referred to as user equipment (UE) or a user. The terminal may specifically receive the configuration information sent by the network device on the network side. The specific type of the network device may be set as required, such as a base station, and is not limited in this embodiment of the present disclosure.

[0111] In actual application, it can be understood that the interference amount is the interference measurement result of the terminal, which can specifically include interference and noise. In addition, it can be understood that the first information, the second information and the third information are configuration information related to interference measurement, that is, the first information, the second information and the third information are used for interference measurement. For example, in a scenario where channel reciprocity exists, the base station (that is, the network side) can obtain the downlink channel only through the SRS sent by the terminal, and the terminal does not need to measure the downlink channel through the CSI-RS; or when the downlink channel changes slowly and the neighboring area interference changes more drastically; or if the CQI calculated by the terminal is based on the single-user MIMO (SU-MIMO) assumption, and after the base station receives the CQI and switches to the MU-MIMO scheduling strategy, the CQI may no longer adapt to the MU-MIMO scheduling assumption, then the terminal can only perform interference measurement based on at least one of the first information, the second information and the third information, and report the interference measurement result (that is, the interference amount) to the base station. The base station can calculate the modulation and coding scheme (MCS) based on the interference measurement reported by the terminal and the base station's MU-MIMO assumptions. This can reduce the base station's CSI-RS overhead for channel measurement, improve the accuracy of the terminal's interference measurement, help the base station perform efficient precoding and scheduling, and reduce the terminal's computational complexity.

[0112] In actual application, the reported quantity includes at least the interference quantity, which means that the reported quantity (reportQuantity) configured by the network side in the CSI-ReportConfig includes at least "interference (which can be expressed as Interference in English)". Exemplarily, when the reported quantity does not include CQI, the base station (i.e., the network side) can configure a CSI-ReportConfig for the terminal, and the CSI-ReportConfig can be associated with only one or two CSI-ResourceConfigs. The reportQuantity in the CSI-ReportConfig (i.e., the above-mentioned first information) can be 'Interference', 'cri-RI-i1-Interference', 'cri-RI-PMI-Interference', 'cri-RI-Interference', or 'cri-RI-LI-PMI-Interference'. Among them, when the CSI-ReportConfig is associated with only one CSI-ResourceConfig (that is, when the configuration information includes the second information but does not include the third information, or when the configuration information includes the third information but does not include the second information), the CSI-ResourceConfig (that is, the above-mentioned second information or third information) can be associated with M0 CSI-RS resource sets (that is, the above-mentioned first resource set or second resource set, M0 is an integer greater than 0 (that is, an integer greater than or equal to 1)), and each CSI-RS resource set contains N0 CSI-IM resources or N0 NZP CSI-RS resources (N0 is an integer greater than 0, and the value of N0 of different CSI-RS resource sets can be the same or different). When CSI-ReportConfig is associated with two CSI-ResourceConfigs (i.e., when the configuration information includes both the second information and the third information), the first CSI-ResourceConfig (i.e., the above-mentioned second information) can be associated with M1 CSI-RS resource sets (i.e., the above-mentioned first resource set, M1 is an integer greater than 0), and each CSI-RS resource set contains N1 CSI-IM resources (N1 is an integer greater than 0, and the value of N1 for different CSI-RS resource sets can be the same or different); the second CSI-ResourceConfig (i.e., the above-mentioned third information) can be associated with M2 CSI-RS resource sets (i.e., the above-mentioned second resource set, M2 is an integer greater than 0), and each CSI-RS resource set contains N2 NZP CSI-RS resources (N2 is an integer greater than 0, and the value of N2 for different CSI-RS resource sets can be the same or different).After receiving the CSI-ReportConfig, the terminal may perform interference measurement according to the CSI-IM resources and / or NZP CSI-RS resources associated with one or two CSI-ResourceConfigs associated with the CSI-ReportConfig, and report the interference amount obtained by the measurement to the base station.

[0113] In one embodiment, the reported quantity may also include CQI; accordingly, the configuration information may also include tenth information, the tenth information is used to indicate at least one third resource set, the at least one third resource set is used for channel measurement (that is, the tenth information is used for channel measurement), and each third resource set includes at least one NZP CSI-RS resource.

[0114] In actual application, the reported quantity may also include CQI, which means that the reporting quantity reportQuantity configured by the network side in the CSI-ReportConfig may include "interference (which can be expressed as Interference in English)" and "CQI". Exemplarily, when the reported quantity includes CQI, the base station (i.e., the network side) may configure a CSI-ReportConfig for the terminal, and the CSI-ReportConfig may be associated with only two or three CSI-ResourceConfigs. The reportQuantity in the CSI-ReportConfig (i.e., the above-mentioned first information) may be 'CQI-Interference', 'cri-RI-PMI-CQI-Interference', 'cri-RI-i1-CQI-Interference', 'cri-RI-CQI-Interference', or 'cri-RI-LI-PMI-CQI-Interference'. Among them, when the CSI-ReportConfig is associated with two CSI-ResourceConfigs (that is, when the configuration information includes the tenth information and the second information or the third information), the first CSI-ResourceConfig (that is, the above-mentioned tenth information) is used for channel measurement, and can be associated with M3 CSI-RS resource sets (that is, the above-mentioned third resource set, M3 is an integer greater than 0), and each CSI-RS resource set contains N3 NZP CSI-RS resources (N3 is an integer greater than 0, and the value of N3 of different CSI-RS resource sets can be the same or different); the second CSI-ResourceConfig (that is, the above-mentioned third information) is used for interference measurement, and can be associated with M4 CSI-RS resource sets (that is, the above-mentioned second resource set, M4 is an integer greater than 0), and each CSI-RS resource set contains N4 NZP CSI-RS resources (N4 is an integer greater than 0, and the value of N4 of different CSI-RS resource sets can be the same or different).When CSI-ReportConfig is associated with three CSI-ResourceConfigs (i.e., when the configuration information includes the tenth information, the second information, and the third information at the same time), the first CSI-ResourceConfig (i.e., the tenth information) is used for channel measurement and can be associated with M5 CSI-RS resource sets (i.e., the third resource set, M5 is an integer greater than 0), and each CSI-RS resource set contains N5 NZPs. CSI-RS resources (N5 is an integer greater than 0, and the value of N5 for different CSI-RS resource sets can be the same or different); the second CSI-ResourceConfig (i.e., the above-mentioned second information) is used for interference measurement, and can be associated with M6 CSI-RS resource sets (i.e., the above-mentioned first resource set, M6 is an integer greater than 0), and each CSI-RS resource set contains N6 CSI-IM resources (N6 is an integer greater than 0, and the value of N6 for different CSI-RS resource sets can be the same or different); the third CSI-ResourceConfig (i.e., the above-mentioned third information) is used for interference measurement, and can be associated with M7 CSI-RS resource sets (i.e., the above-mentioned second resource set, M7 is an integer greater than 0), and each CSI-RS resource set contains N7 NZP CSI-RS resources (N7 is an integer greater than 0, and the value of N7 for different CSI-RS resource sets can be the same or different). After receiving the CSI-ReportConfig, the terminal can perform interference measurement and / or channel measurement based on the CSI-IM resources and / or NZP CSI-RS resources associated with the two or three CSI-ResourceConfigs associated with the CSI-ReportConfig, and report the measured interference amount and / or channel measurement results (i.e., CQI) to the base station.

[0115] Based on this, in one embodiment, the method may further include:

[0116] Perform interference measurement and / or channel measurement based on the configuration information to obtain eleventh information, where the eleventh information includes the interference amount and / or CQI;

[0117] Send the eleventh information to the network side.

[0118] In actual application, since the network side separately configures a resource set for interference measurement (i.e., the first resource set and / or the second resource set) and a resource set for channel measurement (i.e., the third resource set), the decoupling of the terminal channel measurement and the terminal interference measurement is achieved. Therefore, the terminal can use the resource set for interference measurement to perform interference measurement, and / or use the resource set for channel measurement to perform channel measurement; thereafter, the terminal can simultaneously report the interference amount and the CQI to the network side (i.e., the eleventh information includes the interference amount and the CQI), or only report the CQI to the network side (i.e., the eleventh information only includes the CQI), or only report the interference amount to the network side (i.e., the eleventh information only includes the interference amount). Exemplarily, the terminal may report only the CQI at some reporting opportunities (which may be expressed as occasion in English), and report only the interference amount at other reporting opportunities; alternatively, the terminal may report only the CQI at some reporting opportunities, and report the CQI and the interference amount at other reporting opportunities; alternatively, the terminal may report only the interference amount at some reporting opportunities, and report the CQI and the interference amount at other reporting opportunities; alternatively, the terminal may report only the interference amount at some reporting opportunities 1 (which may be expressed as occasion#1 in English), report only the CQI at some reporting opportunities 2 (which may be expressed as occasion#2 in English), and report the CQI and the interference amount at the remaining reporting opportunities except reporting opportunity 1 and reporting opportunity 2.

[0119] In one embodiment, when the configuration information includes the third information, the configuration information may further include at least one fourth information, each fourth information being associated with a second resource set, and the fourth information being used to indicate the cell associated with each NZP CSI-RS resource in the at least one NZP CSI-RS resource included in the associated second resource set.

[0120] In actual application, considering that the interference received by the terminal on different ports is spatially selective, that is, the degree of interference of the terminal on different ports is different, in order to enhance the interference measurement of the terminal, the network side can configure N8 NZP CSI-RS resources for the terminal for interference measurement (N8 is an integer greater than 0). These N8 NZP CSI-RS are sent by N8 adjacent network devices other than the network device currently serving the terminal, and are used to help the terminal measure the downlink channels of N8 adjacent cells; in other words, for the at least one second resource set used for interference measurement, each second resource set can include N8 NZP CSI-RS resources (the value of N8 of different CSI-RS resource sets can be the same or different). Exemplarily, the base station (i.e., the network side) can configure a CSI-ReportConfig for the terminal, and the CSI-ReportConfig can be associated with at least one CSI-ResourceConfig, and at least one CSI-ResourceConfig can be associated with M8 CSI-RS resource sets (i.e., the second resource set mentioned above, M8 is an integer greater than 0), and each CSI-RS resource set can contain N8 NZP CSI-RS resources for interference measurement; at least one CSI-RS resource set among the M8 CSI-RS resource sets configured by the base station can be configured with an additional physical cell identifier (Physical Cell ID, PCI) list (expressed in English as AdditionalPCIList, i.e., the fourth information mentioned above), and the additional PCI list contains N8 additional PCI indexes (expressed in English as AdditionalPCIIndex), and the additional PCI list is used to indicate the PCI corresponding to each NZP CSI-RS resource in the N8 NZP CSI-RS resources. Here, it should be noted that if the base station is configured with an additional PCI list (that is, the configuration information includes the fourth information), the number of additional PCI indexes in the additional PCI list is equal to the number of NZP CSI-RS resources in the corresponding CSI-RS resource set (that is, the second resource set) (both are N8), that is, one NZP CSI-RS resource is associated with one adjacent cell; and the first additional PCI index in the additional PCI list is used to indicate the PCI value corresponding to the first NZP CSI-RS resource in the corresponding CSI-RS resource set, the second additional PCI index is used to indicate the PCI value corresponding to the second NZP CSI-RS resource in the corresponding CSI-RS resource set, and so on. The last additional PCI index in the additional PCI list is used to indicate the PCI value corresponding to the last NZP CSI-RS resource in the corresponding CSI-RS resource set.

[0121] In addition, in actual application, when the configuration information includes both the third information and the tenth information, since the second resource set indicated by the third information and the third resource set indicated by the tenth information both include NZP CSI-RS resources, the terminal can only use the NZP CSI-RS resources in the resource set used for channel measurement (i.e., the third resource set) to measure the CQI and report it to the network side; or, the terminal can also measure the CQI based on all NZP CSI-RS resources associated with the configuration information and report it to the network side. At this time, the at least one second resource set can also be used for channel measurement (i.e., the third information can also be used for channel measurement). Exemplarily, when the base station (i.e., the network side) configures N8 NZP CSI-RS resources for the terminal for interference measurement (i.e., for the at least one second resource set used for interference measurement, each second resource set contains N8 NZP CSI-RS resources), the terminal can perform CQI calculation based on the N8 NZP CSI-RS resources, the CSI-IM resources configured by the base station (i.e., the CSI-IM resources corresponding to the second information), and the CSI-RS resources configured by the base station for channel measurement (i.e., the NZP CSI-RS resources corresponding to the tenth information), and report the calculated CQI to the base station.

[0122] In one embodiment, the configuration information may further include fifth information, where the fifth information is used to indicate a quantization and / or reporting method corresponding to the interference amount.

[0123] In one embodiment, the fifth information may include sixth information, and the sixth information is used to indicate reporting of a first quantization value, where the first quantization value is associated with a first power range; accordingly, the interference amount may include the first quantization value.

[0124] Specifically, in actual application, the network side can configure the terminal to report a broadband interference amount (i.e., the first quantized value) and indicate the number of bits occupied by the broadband interference amount, the corresponding power range, and the step size. Exemplarily, the base station (i.e., the network side) can configure the terminal to report a broadband interference amount of k1 bits (k1 is an integer greater than 0), with a range of [A1, B1] milliwatt decibels (dBm) and a step size of T1 decibels (dB) (T1 ≥ 0).

[0125] In one embodiment, the fifth information may include seventh information, and the seventh information is used to indicate the reporting of a first quantization value and at least one second quantization value, each second quantization value is quantized with reference to the first quantization value, and the first quantization value is associated with the first power range; accordingly, the interference amount may include a first quantization value and at least one second quantization value, or include at least one second quantization value.

[0126] In actual application, the network side can configure the terminal to report the narrowband interference amount (i.e., the second quantized value), that is, configure the terminal to use a differential reporting method to report the interference amount, and indicate the number of bits occupied by the broadband interference amount and the narrowband interference amount, the corresponding power range and step size; then the terminal can report a broadband interference amount (i.e., the first quantized value) and at least one narrowband interference amount. Exemplarily, the base station (i.e., the network side) can define the broadband interference amount by k2bits (k2 is an integer greater than 0), with a range of [A2, B2]dBm and a step size of T2dB (T2≥0); each narrowband interference amount is quantized by K3bits with a step size of T3dB (T3≥0) based on the broadband interference amount.

[0127] In one embodiment, the fifth information may include eighth information, and the eighth information is used to indicate reporting a first quantization matrix, each element of the first quantization matrix occupies K bits, and K is an integer greater than 0; accordingly, the interference amount may include the first quantization matrix.

[0128] The dimension of the first quantization matrix is ​​equal to the square value of a first parameter, and the first parameter represents the number of receiving antennas of the terminal.

[0129] Specifically, in actual application, the terminal can obtain an interference coherence matrix R based on the N8 NZP CSI-RS resources used for interference measurement, which can be expressed by the following formula:

[0130] in, Indicates the downlink equivalent channel measured by the terminal through the nth NZP CSI-RS resource; H n represents the channel between the terminal and the nth base station, P n represents the precoding matrix of the nth base station.

[0131] The network side may configure the terminal to report the broadband interference coherence matrix (i.e., the first quantization matrix), that is, configure the terminal to report the interference coherence matrix R using a uniform quantization reporting method, and indicate the number of bits K occupied by each element in the broadband interference coherence matrix; then the terminal may only report one broadband interference coherence matrix R1, the dimension of R1 is N R ×N R ,N R Indicates the number of receiving antennas of the terminal, that is, R1 has a total of N R 2 elements, each element occupies K bits, that is, the terminal will KN R 2 bits are fed back to the network side.

[0132] In one embodiment, the fifth information may include ninth information, and the ninth information is used to indicate the reporting of at least one basis vector and the channel correlation coefficient corresponding to each basis vector; accordingly, the interference amount may include at least one basis vector and the channel correlation coefficient corresponding to each basis vector.

[0133] The at least one basis vector is obtained based on the first quantization matrix.

[0134] In actual application, the specific type of the basis vector and the specific content of the channel correlation coefficient can be set according to needs. For example, the type of the basis vector may include discrete Fourier transform (DFT) basis vectors, etc., and the channel correlation coefficient corresponding to each basis vector may include amplitude value and phase, etc., which is not limited in this embodiment of the present disclosure.

[0135] Specifically, in actual application, the network side can configure the terminal to report the wideband interference coherence matrix (i.e., the first quantization matrix) or to report the narrowband interference coherence matrix (i.e., the basis vector), that is, configure the terminal to report the interference coherence matrix R using a codebook-based reporting method, and indicate the type and number A of basis vectors (A is an integer greater than 0). Then the terminal can report at least one interference coherence matrix (i.e., a wideband interference coherence matrix and / or a narrowband interference coherence matrix), that is, the terminal can first measure and obtain the wideband interference coherence matrix R1, process the wideband interference coherence matrix R1 into A basis vectors and the channel correlation coefficient corresponding to each basis vector, and then report the A basis vectors and the channel correlation coefficient corresponding to each basis vector to the network side. Exemplarily, assuming that the base station (i.e., the network side) configures the UE (i.e., the terminal) to report the interference coherence matrix R using DFT codebook reporting (i.e., configure the UE to report at least one DFT basis vector and the channel correlation coefficient corresponding to each DFT basis vector), then the UE can report L spatial basis vectors, v i It can represent the i-th spatial basis vector (i∈{0,…,L-1}), where L is configured by high-level signaling; and the UE can report M v Frequency domain basis vectors The dimension of each basis vector is N3×1, where N3=N SB ×R,N SB and R are configured by high-level signaling, N SB represents the number of sub-bands, and R represents the oversampling factor of the sub-band; p is also configured by high-level signaling, and p represents the scaling factor of the number of frequency domain basis vectors selected; at the same time, the UE can report the corresponding L spatial basis vectors and the M v Frequency domain basis vectors The channel correlation coefficient; then the interference coherence matrix on a column l can be expressed as:

[0136] Among them, v i represents the i-th spatial basis vector (i∈{0,…,L-1}); represents the reference amplitude in the first polarization direction, represents the reference amplitude in the second polarization direction; represents the fth frequency domain basis vector of the lth column, f∈{0,…,M v -1}; represents the amplitude corresponding to the fth frequency domain basis vector on the i-th spatial domain basis vector in the first polarization direction of the l-th column; represents the phase corresponding to the fth frequency domain basis vector on the i-th spatial basis vector in the first polarization direction of the l-th column; represents the amplitude corresponding to the fth frequency domain basis vector on the i-th spatial domain basis vector in the second polarization direction of the l-th column; Represents the phase corresponding to the fth frequency domain basis vector on the i-th spatial domain basis vector in the second polarization direction of the l-th column.

[0137] For example, assuming that the base station (i.e., the network side) configures the UE (i.e., the terminal) to report the interference coherence matrix R using the DFT codebook reporting method (i.e., configuring the UE to report at least one DFT basis vector and the channel correlation coefficient corresponding to each DFT basis vector), the UE can report L spatial basis vectors, v i It can represent the i-th spatial basis vector (i∈{0,…,L-1}), where L is configured by high-layer signaling. At the same time, the UE can report the channel correlation coefficients corresponding to these L spatial basis vectors. Then the interference coherence matrix on a column l can be expressed as:

[0138] Among them, v i represents the i-th spatial basis vector (i∈{0,…,L-1}); represents the broadband amplitude corresponding to the i-th spatial basis vector in the first polarization direction, represents the narrowband amplitude corresponding to the i-th spatial basis vector in the first polarization direction; represents the broadband amplitude corresponding to the i-th spatial basis vector in the second polarization direction, represents the narrowband amplitude corresponding to the i-th spatial basis vector in the second polarization direction; represents the phase corresponding to the i-th spatial basis vector in the first polarization direction of the l-th column; Represents the phase corresponding to the i-th spatial basis vector in the second polarization direction of the l-th column.

[0139] Accordingly, an embodiment of the present disclosure further provides an information transmission method, which is applied to a network device (specifically, a base station), and the method includes:

[0140] Send configuration information to the terminal, where the configuration information includes at least one of the following:

[0141] First information, where the first information is used to indicate a reported amount, where the reported amount at least includes an interference amount;

[0142] second information, where the second information is used to indicate at least one first resource set, where the at least one first resource set is used for interference measurement, and each first resource set includes at least one CSI-IM resource;

[0143] The third information is used to indicate at least one second resource set, where the at least one second resource set is used for interference measurement, and each second resource set includes at least one NZP CSI-RS resource.

[0144] In one embodiment, the method may further include:

[0145] Receive eleventh information sent by the terminal, where the eleventh information includes the interference amount and / or CQI.

[0146] Accordingly, an embodiment of the present disclosure further provides an information transmission method, as shown in FIG1 , the method comprising:

[0147] Step 101: The network device sends configuration information to the terminal, where the configuration information includes at least one of first information, second information, and third information;

[0148] Step 102: The terminal receives the configuration information sent by the network device; wherein,

[0149] The first information is used to indicate a reported amount, where the reported amount at least includes an interference amount;

[0150] The second information is used to indicate at least one first resource set, where the at least one first resource set is used for interference measurement, and each first resource set includes at least one CSI-IM resource;

[0151] The third information is used to indicate at least one second resource set, where the at least one second resource set is used for interference measurement, and each second resource set includes at least one NZP CSI-RS resource.

[0152] An information transmission method provided by an embodiment of the present disclosure, wherein a network device sends configuration information to a terminal, and the terminal receives the configuration information sent by the network device, wherein the configuration information includes at least one of the following: first information, wherein the first information is used to indicate a reported amount, and the reported amount includes at least an interference amount; second information, wherein the second information is used to indicate at least one first resource set, wherein the at least one first resource set is used for interference measurement, and each first resource set includes at least one CSI-IM resource; and third information, wherein the third information is used to indicate at least one second resource set, wherein the at least one second resource set is used for interference measurement, and each second resource set includes at least one NZP CSI-RS resource. The solution provided by the embodiment of the present disclosure is that the network side sends configuration information related to interference measurement to the terminal, specifically including at least one of information for indicating a reported amount (the reported amount at least includes an interference amount), information for indicating at least one first resource set (at least one first resource set is used for interference measurement), and information for indicating at least one second resource set (at least one second resource set is used for interference measurement). In this way, the subsequent terminal can directly use the configuration information related to the interference measurement to perform interference measurement to obtain the interference amount that needs to be reported, and directly report the obtained interference amount to the network side, that is, the network side does not need to estimate the interference amount based on the channel measurement result reported by the terminal, but can directly obtain the interference amount measured and reported by the terminal, thereby achieving decoupling of the terminal channel measurement and the terminal interference measurement. Moreover, on the one hand, since the network side separately configures a resource set for interference measurement for the terminal, and the network side does not need to estimate the amount of interference based on the channel measurement results reported by the terminal, the CSI-RS overhead for channel measurement on the network side can be reduced; on the other hand, since the network side does not need to estimate the amount of interference based on the channel measurement results reported by the terminal but can directly obtain the amount of interference measured and reported by the terminal, the accuracy of the terminal interference measurement can be improved, helping the network side to subsequently perform accurate and efficient downlink precoding and resource scheduling, while reducing the computational complexity of the terminal.

[0153] In addition, the solution provided by the embodiment of the present disclosure takes into account that the interference received by the terminal on different ports is spatially selective, that is, the degree of interference of the terminal on different ports is different, so the terminal can use an interference coherence matrix (that is, a quantization matrix) to report the amount of interference, which can help the terminal to suppress neighboring cell interference during PDSCH demodulation on the one hand; on the other hand, by reporting the matrix to the network side, it can help the network side to perform more accurate and efficient downlink precoding and resource scheduling based on the demodulation situation of the terminal.

[0154] In addition, the solution provided by the embodiment of the present disclosure is a physical layer multiple-input multiple-output (MIMO) technical solution. The solution provided by the embodiment of the present disclosure can improve the communication performance of network equipment (such as base stations, etc.).
