Large bandwidth refers to a technology that allows faster network transmission and faster data transmission and communication. Massive antennas refer to a technology that can transmit and receive signals in multiple directions at the same time by utilizing multiple antenna elements. However, although these technologies can increase the speed of wireless connections, they also lead to a significant increase in base station energy consumption.

CSI may include parameters such as signal-to-noise ratio, rank indication, and channel quality indicator (CQI), which are used to evaluate the quality and performance of the channel. At present, in order to save energy consumption of base stations, antenna shutdown or power adjustment can be used. After the base station enters the energy-saving state, the channel between the base station and the user equipment (UE) will change, so it is necessary to update the channel state in a timely manner to avoid affecting the accuracy and efficiency of the terminal's scheduling of data. The base station can have multiple sets of energy-saving configurations in the energy-saving state, and each set of energy-saving configurations corresponds to different configurations. How to enable the UE to measure and report CSI according to different configurations is a technical problem that needs to be solved at present. Summary of the invention

[0026] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] It should be understood that in the description of the embodiments of the present invention, if there is a description of "first", "second", etc., it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the order of the indicated technical features.

For example, A and / or B can represent the situation where A exists alone, A and B exist at the same time, and B exists alone. Among them, A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship.

For example, at least one of a, b and c can represent: a, b, c, a and b, a and c, b and c, or a and b and c, where a, b, c can be single or multiple.

[0028] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] In order to facilitate understanding of the solutions of the embodiments of the present application and to make the description of the following embodiments clear and concise, a brief introduction to the relevant technologies is first given:

[0030] Feedback channel: refers to the channel that transmits part or all of the received information to the receiving end through a certain path when the communication system uses link adaptation technology. The feedback channel is also part of the wireless channel. In the field of wireless communications, the wireless channel is a channel that uses radio wave signals as the transmission medium to transmit data signals, which is commonly referred to as the wireless "frequency band". In the application of link adaptation technology, the receiving end needs to adjust the communication link parameters based on the channel state information, which is transmitted from the receiving end to the sending end through the feedback channel.

[0031] Channel State Information (CSI) refers to information that describes the characteristics and conditions of a wireless channel. CSI may include parameters such as signal-to-noise ratio, rank indicator, and channel quality indicator (CQI), which are used to evaluate the quality and performance of a channel.

[0032] CSI measurement: refers to the process of measuring and acquiring CSI. In wireless communication systems, in order to obtain information about the quality and characteristics of the channel, CSI can be measured through different technologies and methods.

[0033] Figure 1 FIG. 1 is a schematic diagram of an embodiment of a wireless communication system for sending a CSI report. In one embodiment, the wireless communication system 100 includes a user equipment 101 (UE) and a network device 102. Figure 1 A specific number of user devices 101 and network devices 102 are depicted in FIG. 1 , but those skilled in the art will appreciate that any number of user devices 101 and network devices 102 may be included in the wireless communication system 100 .

[0034] The user equipment 101, which can also be called a mobile station (MS), a mobile terminal (MT), a terminal, etc., is a device that provides voice and / or data connectivity to a user, or a chip set in the device, for example, a handheld device with wireless connection function, a vehicle-mounted device, etc. At present, some examples of terminal devices are: mobile phones, desktop computers, tablet computers, laptop computers, PDAs, mobile Internet devices (MID), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control (Industrial Control), wireless terminals in self-driving (Self Driving), wireless terminals in remote medical surgery (Remote Medical Surgery), wireless terminals in smart grids (Smart Grid), wireless terminals in transportation safety (Transportation Safety), wireless terminals in smart cities (Smart City), wireless terminals in smart homes (Smart Home), home gateway devices (5G-Residential Gateway, 5G-RG) supporting 5G access, etc.

[0035] The client of the application is installed on the user device 101. An application, also known as application software (APP), is a computer program for completing one or more specific tasks, and usually needs to interact with the user, such as video applications, game applications, social applications, etc.

[0036] The network device 102 may be a base station, customer premises equipment (Customer Premise equipment, CPE), access point (Access Point, AP), home gateway (Residential Gateway) and other equipment. The network device 102 includes an ingress edge device (Ingress Provider Edge, Ingress PE) and an egress edge device (Egress Provider Edge, Egress PE). Among them, the ingress edge device is a network device or node located at the edge of the edge network, responsible for introducing external traffic of the terminal device into the network. The ingress edge device is a key component in the service provider network, which is used to connect the external network and the service provider network, and introduce external traffic into the service provider network for further routing and transmission. The ingress edge device can be a physical device such as a router or a switch, or it can be a server that deploys a virtual router or a virtual switch. The egress edge device is paired with the ingress edge device and can form an edge router pair together. The egress edge device is used to transmit traffic in the network to the external network. The egress edge device is connected to the cloud for communication. The user device 101 is connected to the ingress edge device of the network edge device for communication.

[0037] Technologies such as large bandwidth and massive antennas are widely used in 5G communication systems. Large bandwidth refers to a technology that allows faster network transmission and faster data transmission and communication. Massive antennas refer to a technology that can transmit and receive signals in multiple directions at the same time by utilizing multiple antenna elements. However, although these technologies can increase the speed of wireless connections, they also lead to a significant increase in base station energy consumption.

[0038] At present, in order to save energy consumption of base stations, antenna shutdown or power adjustment can be adopted. After the base station enters the energy-saving state, the channel between the base station and the user equipment (UE) will change, so it is necessary to update the channel state in time to avoid affecting the accuracy and efficiency of the terminal's data scheduling. The base station can have multiple sets of energy-saving configurations in the energy-saving state, and the configuration corresponding to each set of energy-saving configurations is also different. How to enable the UE to measure and report CSI according to different configurations is a technical problem that needs to be solved at present.

[0039] In order to solve the above problems, an embodiment of the present invention provides a channel state information processing method, which enables the UE to perform CSI measurement and reporting according to different configurations, thereby improving the accuracy and efficiency of data scheduling.

[0040] The embodiments described in the present invention may be implemented in a communication system, such as in at least one of the following systems: Global System for Mobile Communications (GSM) or any other second generation cellular communication system, Universal Mobile Telecommunications System (UMTA, 3G) based on basic Wideband Code Division Multiple Access (W-CDMA), High-Speed ​​Packet Access (HSPA), Long Term Evolution (LTE), Advanced LTE, systems based on IEEE 802.11 specifications, systems based on IEEE 802.15 specifications and / or fifth generation (5G) mobile or cellular communication systems or 6G mobile systems; and future mobile communication systems. However, the embodiments are not limited to the systems given in the above examples, but those skilled in the art may apply the solutions to other communication systems having the necessary attributes.

[0041] The channel state information processing method of the embodiment of the present invention can be applied to various types of networks, including but not limited to the following networks, such as Internet Protocol (IP) network, Synchronous Digital Hierarchy (SDH) network, Packet Transport Network (PTN), IP Radio Access Network, etc.

[0042] like Figure 2 As shown, it is a flow chart of a channel state information processing method provided by an embodiment of the present invention, which is applied to user equipment 101. The implementation process of the method may include but is not limited to the following steps S210 to S230. Each step is introduced in turn below:

[0043] Step S210: Receive high-level configuration signaling, where the high-level configuration signaling includes a CSI report configuration, and the CSI report configuration includes at least one sub-configuration.

[0044] It should be noted that high-level configuration signaling refers to RRC signaling or MAC control element (MAC Control Element, MAC CE) signaling, which is used to send CSI report configuration information. CSI report configuration refers to configuration information related to configuring CSI measurement reporting. Sub-configuration is associated configuration information corresponding to a set of sub-CSI reports. It can be understood that the user equipment 101 can perform CSI measurement and reporting according to the high-level configuration signaling. Each sub-configuration is associated with a different antenna state or power state. Each sub-configuration has a corresponding associated channel state information-reference signal CSI-RS resource. When the sub-configuration is configured with the first configuration information and / or the third configuration information, or the sub-configuration is only configured with the third configuration information, the sub-configuration is associated with all CSI-RS resources in the CSI-RS resource set associated with the CSI report configuration. When the sub-configuration is configured with the second configuration information, the sub-configuration is associated with part of the CSI-RS resources in the CSI-RS resource set associated with the CSI report configuration. The sub-configuration configured with the second configuration information may indicate a resource identifier (resource ID) of one or more CSI-RS resources, and the one or more CSI-RS resources are resources associated with the sub-configuration and used for channel measurement.

[0045] It should be noted that the CSI report configuration is associated with a CSI-RS resource set (Resource Set), the CSI-RS resource set includes K CSI-RS resources, and each sub-configuration corresponds to one or more CSI-RS resources in the associated CSI-RS resource set, where K is a positive integer.

[0046] It is understandable that a CSI-RS resource set may include (configure) one or more CSI-RS resources, and the number of ports of each CSI-RS resource may be one of 1, 2, 4, 8, 12, 16, 24, and 32. However, in the related art, when only one CSI-RS resource is configured in a CSI-RS resource set, the maximum number of ports of its CSI-RS resource may be 32; when two CSI-RS resources are configured in a CSI-RS resource set, the maximum number of ports of each CSI-RS resource may be 16; when more than two CSI-RS resources are configured in a CSI-RS resource set; the maximum number of ports of each CSI-RS resource may be 8. This restriction will limit the configuration of the sub-configuration. In a CSI report configuration with sub-configurations, the CSI-RS resources associated with different sub-configurations may be different. Therefore, when a CSI-RS resource set is configured with a large number of CSI-RS resources, the number of ports of each CSI-RS resource will be limited, thereby limiting the application scenarios of sub-configurations containing one or more CSI-RS resources.

[0047] Based on this, in the embodiment of the present invention, when K=A1, the CSI-RS resource set is configured with no more than 32 CSI-RS ports; when K=A2, the CSI-RS resource set is configured with no more than 16 CSI-RS ports; when K=A3, the CSI-RS resource set is configured with no more than 8 CSI-RS ports. The values ​​of A1, A2 and A3 are related to at least one of the following: the sub-configuration type configured in the CSI report configuration, the number of sub-configurations configured in the CSI report configuration, the CSI report time domain type, the maximum number of sub-configurations that can be configured in the CSI report configuration, the maximum number of sub-configurations that can be triggered by a trigger state of DCI or MAC CE in a CSI report configuration, or the capability parameters of the user equipment.

[0048] It should be noted that the CSI report time domain type includes any of the types such as periodic, semi-persistent, and aperiodic.

[0049] It can be understood that A1, A2 and A3 refer to the number of CSI-RS resources configured in the CSI-RS resource set.

[0050] It should be noted that the values ​​of A1, A2 and A3 are associated with the sub-configuration type configured in the CSI report configuration. For example, when the user equipment 101 reports support for restrictions on resource configuration according to the sub-configuration, and the CSI report configuration contains a sub-configuration configured with the second configuration information, the resources associated with the sub-configuration in the CSI report configuration are configured according to the restrictions on resource configuration of the sub-configuration; otherwise, the resources associated with the CSI report configuration are configured according to the restrictions on resource configuration of the CSI report configuration, and A1, A2, and A3 are loose values. Among them, the loose value of A1 means A1>1, the loose value of A2 means A2>2, and the loose value of A3 is A3>8. For example, A1=4, A2=8, and A3=16.

[0051] In another example, the values ​​of A1, A2, and A3 are associated with the sub-configuration type configured in the CSI report configuration. When the CSI report configuration includes a sub-configuration configured with the second configuration information, the resources associated with the sub-configuration in the CSI report configuration are configured according to the resource configuration restrictions of the sub-configuration; otherwise, the resources associated with the CSI report configuration are configured according to the resource configuration restrictions of the CSI report configuration. Where A1 = 1, A2 = 2, A3 = 8.

[0052] As another example, different sub-configuration types are based on different configuration restrictions. For example, when the CSI report configuration includes a sub-configuration configured with the second configuration information, the resources associated with the sub-configuration in the CSI report configuration are configured according to the restrictions on resource configuration of the sub-configuration, otherwise, the resources associated with the CSI report configuration are configured according to the restrictions on resource configuration of the CSI report configuration, and A1, A2, A3 are relaxed A1, A2, A3 values.

[0053] It should be noted that the first configuration information refers to at least one of the rank restriction parameter, codebook subset restriction parameter, port subset indication parameter, the number parameter n1 of antenna ports in the first dimension, the number parameter n2 of antenna ports in the second dimension, and the number parameter ng of antenna port panels included in the sub-configuration.

[0054] It should be noted that the Rank Indicator is a parameter used to indicate the maximum MIMO level that the receiving device can support. The Rank Restriction Parameter is a parameter used to limit the RI value fed back by the UE. The Codebook Subset Restriction Parameter refers to a parameter used to limit the selection range of the codebook. The Codebook Subset Restriction Parameter can ensure that an appropriate codebook subset is selected in a MIMO system to match the channel conditions and antenna configuration. The Port Subset Indicator Parameter refers to a parameter used to indicate a CSI-RS antenna port subset. The Port Subset Indicator Parameter is used to determine the corresponding transmission and reception configuration. The number parameter n1 of antenna ports in the first dimension is the number of antenna ports in the first dimension (horizontal direction) associated with the CSI-RS antenna port, that is, a parameter used to describe the scale of the antenna configuration. The number parameter n2 of antenna ports in the second dimension is the number of antenna ports in the second dimension (vertical direction) associated with the CSI-RS antenna port, that is, it is also a parameter used to describe the scale of the antenna configuration. The parameter ng of the number of antenna port panels represents the number of antenna port panels, that is, a parameter used to describe the scale and distribution of the antenna configuration.

[0055] The embodiments of the present invention set these parameters, which can be used to describe important parameters such as antenna configuration, channel status and system performance, so as to perform appropriate signal processing and data stream allocation during the transmission process. Different values ​​and combinations can adjust the capacity, reliability and transmission efficiency of the system.

[0056] It should be noted that the second configuration information refers to one or more CSI-RS resources in the CSI-RS resource set associated with the sub-configuration. Or the second configuration information refers to one or more CSI-RS resource IDs or resource ID lists in the CSI-RS resource set associated with the sub-configuration.

[0057] It should be noted that the sub-configuration type refers to the content of the sub-configuration configuration, and different configuration information represents different sub-configuration types.

[0058] It should be noted that the values ​​of A1, A2 and A3 are associated with the capability parameters of the user equipment. The capability parameters of the user equipment refer to the capabilities reported by the user equipment to the network equipment. The capability parameters of the user equipment may indicate: whether the user equipment supports the loose values ​​of A1, A2 and A3, the scaling factor (f) used to calculate A1, A2 or A3 (for example, A1=A1*f, different A1, A2 or A3 may be associated with the same or different scaling factors), the offset value (b) used to calculate A1, A2 or A3 (for example, A1=A1+b, different A1, A2 or A3 may be associated with the same offset value or one offset value respectively), the loose values ​​of A1, A2 and A3, the sub-configuration type corresponding to the loose values ​​of A1, A2 and A3 supported by the user equipment, whether the user equipment supports the sub-configuration type for resource configuration according to the sub-configuration restriction, whether the resource configuration restriction is performed according to the sub-configuration, etc. Among them, the restriction on whether to configure resources according to sub-configuration refers to the CSI-RS resources associated with a sub-configuration, which needs to satisfy that if K=A1 CSI-RS resources are configured, the resource is configured with a maximum of 32 CSI-RS ports. If K=A2 CSI-RS resources are configured, each resource is configured with a maximum of 16 CSI-RS ports. If K=A3 CSI-RS resources are configured, each resource is configured with a maximum of 8 CSI-RS ports. In some embodiments, A1=1, A2=2, A3=8.

[0059] Exemplarily, in one embodiment, a CSI report configuration includes one or more sub-configurations configured with the first configuration information or the third configuration information, and in the CSI-RS resource set associated with the CSI report configuration, A1=2, 3 or 4, A2=3 or 4, A3=integer greater than or equal to 8 or less than or equal to 12 are used. For example, A1=2, A2=4, A3=8. In another example, A1=4, A2=8, A3=16.

[0060] Exemplarily, in another embodiment, a CSI report configuration includes one or more sub-configurations configured with the second configuration information, and in the CSI-RS resource set associated with the CSI report configuration, the restrictions of A1=2, 3, or 4, A2=an integer greater than or equal to 2 or less than or equal to 8, and A3=an integer greater than or equal to 8 or less than or equal to 16 are used. For example, A1=4, A2=8, and A3=16.

[0061] In some embodiments, the UE capability reports the value of the supported relaxations A1, A2, or A3.

[0062] In some embodiments, the value of A1, A2, or A3 is related to the number of sub-configurations configured in the CSI report configuration. For example, if there are X sub-configurations configured in a CSI report configuration, then A1 = X, or A2 = 2*X, or A3 = A3*X, or A1 = A1+X, or A2 = A2+X, or A3 = A3+X. For example, if there are X sub-configurations configured in a CSI report configuration, then A2 = 2*X or A3 = 4*X.

[0063] In some embodiments, the value of A1, A2, or A3 is related to the maximum number of sub-configurations that can be configured in the CSI report configuration. For example, a maximum of Y sub-configurations can be configured in a CSI report configuration, then A1 = Y. For example, a maximum of Y sub-configurations can be configured in a CSI report configuration, then A2 = 2*Y or A3 = 4*Y.

[0064] In some embodiments, the value of A1, A2, or A3 is related to the maximum number of sub-configurations that can be triggered by a trigger state of DCI or MAC CE in a CSI report configuration. For example, the maximum number of sub-configurations that can be triggered by a trigger state of DCI or MAC CE in a CSI report configuration is N, then A1 = N. For example, the maximum number of sub-configurations that can be triggered by a trigger state of DCI or MAC CE in a CSI report configuration is A2 = 2*N or A3 = 4*N.

[0065] In some embodiments, the value of A1, A2, or A3 is related to at least one of the following: CSI report time domain type (such as periodic, semi-persistent, aperiodic), the number of sub-configurations configured in the CSI report configuration (X), the maximum number of sub-configurations that can be configured in the CSI report configuration (Y), the maximum number of sub-configurations that can be triggered by a trigger state of DCI or MAC CE in a CSI report configuration (N), and UE capabilities.

[0066] For example, when the CSI reporting time domain type is periodic, the value of A1, A2, or A3 is related to Y (for example, A1=Y, or A2=2*Y, or A3=A3*Y, or A1=A1+Y, or A2=A2+Y, or A3=A3+Y); when the CSI reporting time domain type is semi-continuous or non-periodic, the value of A1, A2, or A3 is related to N (for example, A1=N, or A2=2*N, or A3=A3*N, or A1=A1+N, or A2=A2+N, or A3=A3+N).

[0067] For example, when the CSI reporting time domain type is periodic, the value of A1, A2, or A3 is related to X (for example, A1=X, or A2=2*X, or A3=A3*X, or A1=A1+X, or A2=A2+X, or A3=A3+X); when the CSI reporting time domain type is semi-continuous or non-periodic, the value of A1, A2, or A3 is related to N (for example, A1=N, or A2=2*N, or A3=A3*N, or A1=A1+N, or A2=A2+N, or A3=A3+N).

[0068] Wherein, in some embodiments, the maximum number of sub-configurations (Y) that can be configured in the CSI report configuration, and the maximum number of sub-configurations (N) that can be triggered by a trigger state of DCI or MAC CE in a CSI report configuration, are reported by UE capabilities. In some embodiments, the maximum number of sub-configurations (Y) that can be configured in the CSI report configuration, and the maximum number of sub-configurations (N) that can be triggered by a trigger state of DCI or MAC CE in a CSIreport configuration, are predefined.

[0069] In some embodiments, the UE capability reporting supports the number of sub-configurations that can be configured in a CSI report configuration, and the maximum number of sub-configurations that can be configured in the CSI report configuration is the maximum value thereof. In some embodiments, the UE capability reporting supports the number of sub-configurations that can be triggered by a trigger state in the CSI report configuration, and the maximum number of sub-configurations that can be triggered by a trigger state of DCI or MAC CE in a CSI report configuration is the maximum value thereof.

[0070] In some embodiments, the value of A1, A2, or A3 is related to the number of sub-configurations that the UE capability reporting supports that can be configured in a CSI report configuration, or the number of sub-configurations that the UE capability reporting supports that can be triggered by a trigger state in a CSI report configuration.

[0071] In one embodiment, the CSI report configuration further includes a codebook configuration (codebookConfig), wherein the first type of parameters are configured in the codebook configuration. In one embodiment, the CSI report configuration further includes a codebook configuration (codebookConfig), wherein the codebook configuration is used to calculate the CSI of the number of ports configured in the CSI-RS resource associated with the CSI report configuration.

[0072] For example, Figure 3 As shown, the CSI report configuration includes a sub-configuration list and a codebook configuration. The sub-configuration list includes at least one sub-configuration, such as sub-configuration #1, sub-configuration #2, etc.

[0073] Step S220: For at least one sub-configuration, generate a sub-CSI report corresponding to the sub-configuration.

[0074] In one embodiment, generating a sub-CSI report corresponding to the sub-configuration includes: determining the sub-CSI report corresponding to the sub-configuration according to the first type of parameters and the CSI-RS resource correspondingly associated with the sub-configuration.

[0075] It can be understood that the first type of parameters refers to parameters used to determine the sub-CSI report. Figure 3 As shown, the first type of parameters include the first type of parameters configured in the codebook configuration and / or the first type of parameters configured in the sub-configuration.

[0076] It should be noted that the first category of parameters includes at least one of a rank restriction parameter, a codebook subset restriction parameter, a port subset indication parameter, a number parameter n1 of antenna ports in the first dimension, a number parameter n2 of antenna ports in the second dimension, and a number parameter ng of antenna port panels.

[0077] In one embodiment, when the first condition is not met, the first type of parameters configured in the codebook configuration are considered, and the first type of parameters in the codebook configuration are used to determine the sub-CSI report corresponding to the sub-configuration in which the first type of parameters are not configured, that is, the first type of parameters in the codebook configuration are used to determine the CSI calculation corresponding to the sub-configuration in which the first type of parameters are not configured.

[0078] It should be noted that the first condition includes one of the following:

[0079] (1) Some sub-configurations in the CSI report configuration are configured with first-category parameters, and the number of ports associated with at least one sub-configuration configured with the first-category parameters is equal to the number of ports configured in the CSI-RS resource set associated with the CSI report configuration;

[0080] (2) All sub-configurations in the CSI report configuration are configured with the first type of parameters;

[0081] (3) When the CSI report configuration does not include a sub-configuration containing only the third configuration information or only the second configuration information;

[0082] (4) The first type of parameters configured in the codebook configuration indicated by the high-level configuration signaling are ignored;

[0083] (5) The CSI report configuration includes at least one sub-configuration configured with the first type of parameters.

[0084] In another embodiment, when the first condition is met, the first type of parameters configured in the codebook configuration are ignored, and the first type of parameters used in the sub-CSI report corresponding to the sub-configuration are determined to be obtained by one of the following methods:

[0085] In the case where the sub-configuration is configured with first-category parameters, the first-category parameters are obtained from the sub-configuration;

[0086] or,

[0087] When the sub-configuration is not configured with the first type of parameters, the first type of parameters are obtained from other sub-configurations, wherein the number of ports associated with the other sub-configurations is equal to the number of ports configured in the CSI-RS resource set associated with the CSI report configuration.

[0088] The embodiment of the present invention sets a first condition to determine a method for obtaining a first type of parameter used in a sub-CSI report corresponding to a sub-configuration, so that the UE performs CSI measurement and reporting according to different configurations, effectively saving energy consumption of network equipment and improving the efficiency and accuracy of data adjustment.

[0089] In one embodiment, when the second condition is met, the CSI report configuration is configured with the first type of parameters only in the sub-configuration. In one embodiment, when the second condition is met, the CSI report configuration does not configure the first type of parameters in the codebook configuration.

[0090] It should be noted that the second condition includes one of the following:

[0091] (1) Some sub-configurations in the CSI report configuration are configured with first-category parameters, and the number of ports associated with at least one sub-configuration configured with the first-category parameters is equal to the number of ports configured in the CSI-RS resource set associated with the CSI report configuration;

[0092] (2) All sub-configurations in the CSI report configuration are configured with the first type of parameters;

[0093] (3) Specific behaviors indicated by high-level configuration signaling;

[0094] (4) Each sub-configuration in the CSI report configuration includes only a sub-configuration containing only the first configuration information;

[0095] (5) The CSI report configuration includes at least one sub-configuration configured with the first type of parameters.

[0096] It should be noted that, for a CSI report configuration configured with one or more sub-configurations, when at least one sub-configuration includes the first configuration information and / or the third configuration information, and the CSI report configuration has only the first type of parameters configured in the sub-configuration, and at least one sub-configuration includes only the third configuration information, the first type of parameters of the sub-configuration including only the third configuration information are obtained by at least one of the following:

[0097] Get the first-category parameters from the sub-configuration with the smallest sub-configuration index that is configured with the first-category parameters.

[0098] or,

[0099] Get the first-class parameters from the sub-configuration that is configured with the first-class parameters and has the largest number of associated ports.

[0100] or,

[0101] Get the first-category parameter from the predefined first-category parameters;

[0102] or,

[0103] Get first-class parameters from default first-class parameters;

[0104] or,

[0105] Get the first type of parameters from the predefined sub-configuration;

[0106] or,

[0107] The first type of parameters are obtained from the codebook configuration.

[0108] It should be noted that the default first-category parameters are the default values ​​set flexibly for the rank restriction parameters, codebook subset restriction parameters, port subset indication parameters, antenna port quantity parameter n1 in the first dimension, antenna port quantity parameter n2 in the second dimension, antenna port panel quantity parameter ng, etc. contained therein according to actual conditions. In some embodiments, these default values ​​will be set in the protocol. For example, the codebook subset restriction parameter defaults to all 1s (i.e., there are no codebooks that cannot be reported), or the rank restriction parameter defaults to all 1s (i.e., there are no rank restriction parameter values ​​that cannot be reported), or the antenna port quantity parameter n1 in the first dimension, the antenna port quantity parameter n2 in the second dimension, and the antenna port panel quantity parameter ng default to the n1, n2 combination with the smallest N1 corresponding to the number of ports configured for the associated CSI-RS resource, or there is no ng parameter by default, i.e., there is only one panel.

[0109] It should be noted that the predefined first-category parameters indicate that first-category parameters for different port numbers will be predefined in the protocol. When the first-category parameters are not configured in the sub-configuration, the predefined first-category parameters associated with the number of ports configured for the corresponding CSI-RS resource are used. For example, different first-category parameters corresponding to different port numbers are predefined, and the predefined first-category parameters are selected according to the number of ports.

[0110] It should be noted that the third configuration information refers to the power offset value (power offset) configured in the sub-configuration.

[0111] It should be noted that a sub-configuration may include one or more of the first configuration information, the second configuration information, and the third configuration information, but the same sub-configuration cannot include both the first configuration information and the second configuration information. A sub-configuration configured in a CSI report configuration cannot include both a sub-configuration including the first configuration information and a sub-configuration including the second configuration information.

[0112] The embodiment of the present invention sets the second condition to determine the configuration status of the first type of parameters in the sub-configuration of the CSI report configuration, so that the UE can perform CSI measurement and reporting according to different CSI configurations, effectively saving energy consumption of network equipment and improving the efficiency and accuracy of data adjustment.

[0113] In one embodiment, for a CSI report configuration configured with one or more sub-configurations, when the third condition is met, the first type of parameters are configured in the codebook configuration in the CSI report configuration.

[0114] It should be noted that the third condition includes one of the following:

[0115] (1) At least one sub-configuration in the CSI report configuration is configured with a first type of parameter, and the number of ports not indicated in at least one sub-configuration configured with the first type of parameter is equal to the number of ports configured in the CSI-RS resource set associated with the CSI report configuration;

[0116] (2) The CSI report configuration includes one or more sub-configurations configured with only the third configuration information;

[0117] (3) The CSI report configuration includes one or more sub-configurations configured with the second configuration information;

[0118] (4) Specific actions indicated by high-level configuration signaling.

[0119] It should be noted that, for a CSI report configuration configured with one or more sub-configurations, if the one or more sub-configurations simultaneously include a sub-configuration configured with the first configuration information and a sub-configuration configured with the third configuration information, the number of ports indicated / associated in at least one sub-configuration configured with the first configuration information is equal to the number of ports configured in the CSI-RS resource set associated with the CSI report configuration. At this time, the CSI report configuration does not have any first-category parameters other than those configured in the sub-configuration.

[0120] It should be noted that, for a CSI report configuration configured with one or more sub-configurations, if the one or more sub-configurations simultaneously include a sub-configuration configured with the first configuration information and a sub-configuration configured with the third configuration information, and the number of ports indicated / associated in none of the sub-configurations configured with the first configuration information is equal to the number of ports associated / configured in the CSI-RS resource set associated with the CSI report configuration. At this time, the CSI report configuration does not include a sub-configuration configured with only the third configuration information.

[0121] It should be noted that when a CSI report configuration contains at least one sub-configuration indicating the same number of ports as "the number of ports configured in the CSI-RS resources associated with the CSI report configuration", the first category parameters configured in codebookConfig are the same as the first category parameters configured in the sub-configuration.

[0122] In one embodiment, before generating a sub-CSI report corresponding to the sub-configuration for at least one sub-configuration in step S220, the channel state information CSI processing method provided by the embodiment of the present invention also includes: receiving downlink control information DCI from a physical downlink control channel PDCCH, wherein the DCI indicates a CSI report configuration for reporting the CSI report and triggers one or more sub-configurations configured therein.

[0123] It should be noted that the Physical Downlink Control Channel (PDCCH) is an important channel in a wireless communication system, which is used to transmit system control information to coordinate and control downlink communication of a User Equipment (UE).

[0124] It can be understood that, for at least one sub-configuration, generating a sub-CSI report corresponding to the sub-configuration includes: for each triggered sub-configuration, generating a sub-CSI report corresponding to the triggered sub-configuration.

[0125] It is understandable that when one CSI report configuration is configured with one or more sub-configurations, and the DCI trigger is greater than one sub-configuration, the user equipment needs to report multiple sets of sub-CSI reports.

[0126] Step S230: Send a CSI report including at least one sub-CSI report.

[0127] It should be noted that a CSI report refers to a report that includes at least one sub-CSI report that needs to be reported by a user equipment. That is, multiple sets of sub-CSI reports that need to be reported in the same CSI report configuration are in the same CSI report.

[0128] In one embodiment, since the corresponding processing time will also increase when the user equipment reports multiple sets of sub-CSI reports, sending a CSI report including at least one sub-CSI report includes:

[0129] When the first time is greater than the first threshold and the second time is greater than the second threshold, a CSI report including at least one sub-CSI report is sent through the physical uplink shared channel PUSCH; wherein the first time represents the time length between the end symbol of the PDCCH and the start symbol of the PUSCH; the second time represents the time length between the non-periodic CSI-RS resource associated with the CSI report, or the end symbol of the measurement resource associated with the CSI report and the start symbol of the PUSCH.

[0130] It can be understood that the first threshold is used to indicate whether the first time representing the time length between the end symbol of the PDCCH and the start symbol of the PUSCH reaches or exceeds the value of the preset condition. The second threshold is used to indicate / characterize whether the second time representing the time length between the end symbol of the non-periodic CSI-RS resource associated with the CSI report, or the end symbol of the measurement resource associated with the CSI report and the start symbol of the PUSCH reaches or exceeds the value of the preset condition.

[0131] It should be noted that the first threshold is related to the first parameter, and the second threshold is related to the second parameter. Under the same circumstances, the larger the value of the first parameter, the larger the first threshold, and the larger the value of the second parameter, the larger the second threshold. The first parameter and the second parameter are mainly related to the time for the user equipment to process / prepare the CSI report.

[0132] In the embodiment of the present invention, when the first time is greater than the first threshold and the second time is greater than the second threshold, a CSI report including at least one sub-CSI report is sent through a physical uplink shared channel PUSCH. For different situations, the processing time required by the UE may be different. Different first parameters and second parameters are used, so that the first threshold and the second threshold are different, which can meet the processing time requirements of the UE in different situations, thereby ensuring the processing of CSI and improving the scheduling efficiency of data.

[0133] It should be noted that the values ​​of the first parameter and the second parameter are related to at least one of the following:

[0134] The number of ports associated with the CSI-RS resources corresponding to the triggered sub-configuration;

[0135] The number of CSI-RS ports indicated by the triggered sub-configuration;

[0136] The maximum number of CSI-RS ports indicated by the triggered sub-configuration;

[0137] The sum of the number of CSI-RS ports associated / indicated by the triggered sub-configuration;

[0138] The number of sub-configurations triggered;

[0139] Frequency characteristics of the reported CSI reports;

[0140] Capability parameters of user equipment;

[0141] The type of subconfiguration that was triggered.

[0142] It should be noted that the frequency characteristics of the reported CSI report refer to the reporting method of CSI under different frequency bandwidths used in the wireless communication system. The frequency characteristics of the reported CSI report include broadband CSI reporting methods and narrowband CSI reporting methods. Broadband CSI reporting can provide more comprehensive channel state information and is suitable for larger frequency bandwidths, such as scenarios for large data transmission. Narrowband CSI reporting can provide more accurate and detailed channel state information and is suitable for smaller frequency bandwidths, such as scenarios for smaller data transmission. Therefore, the frequency characteristics of the reported CSI report can be set according to actual needs to determine the values ​​of the first parameter and the second parameter.

[0143] It should be noted that the first parameter and / or the second parameter include corresponding loose values ​​and tightened values. Therefore, when the fourth condition is met, the first parameter and / or the second parameter takes the corresponding loose values.

[0144] It should be noted that the loose value refers to the value after the parameter requirements in the system are moderately relaxed. The loose value can give the UE more processing time when processing some complex CSI measurement calculations. In contrast, the tightened value is equivalent to the unrelaxed value, which refers to the processing time when the requirements for conditions or restrictions are relatively strict and the time requirements are tight.

[0145] It should be noted that the fourth condition includes one of the following:

[0146] (1) The number of triggered sub-configurations is greater than a third threshold, where the third threshold is an integer greater than or equal to 2;

[0147] (2) The CSI report is reported in narrowband CSI reporting mode;

[0148] (3) The number of ports of the CSI-RS resource associated with the triggered sub-configuration is greater than a fourth threshold, where the fourth threshold is an integer less than or equal to 4;

[0149] (4) The sum of the number of CSI-RS ports associated / indicated by the triggered sub-configuration is greater than a fifth threshold, where the fifth threshold is an integer less than or equal to 8;

[0150] (5) the user capability parameter indicates that the first parameter and / or the second parameter take corresponding loose values;

[0151] (6) The type of the triggered sub-configuration is the first type, where the first type indicates a sub-configuration configured with the first configuration information or the second configuration information;

[0152] (7) The number of ports of the maximum CSI-RS resource associated with the triggered sub-configuration is greater than a fourth threshold, where the fourth threshold is an integer less than or equal to 4.

[0153] It should be noted that, as shown in Table 1, Z2, Z2', Z1, and Z1' in Table 1 are used to represent predefined values. Therefore, the representation that the first parameter (Z) and / or the second parameter (Z') take corresponding loose values ​​includes one of the following:

[0154] (1) Z = Z2 + Z2';

[0155] (2) Z = n*Z2 + m*Z1, where m is an integer greater than or equal to 1, and n is an integer greater than or equal to 1;

[0156] (3) Z = n*Z2 + m*Z2', m is an integer greater than or equal to 1, and n is an integer greater than or equal to 1;

[0157] (4) Z = Z2*n, where n is an integer greater than or equal to 2;

[0158] (5) Z' = 2*Z2';

[0159] (6) Z'=Z2'*n, where n is an integer greater than or equal to 2;

[0160] (7) Z' = Z2 + Z2';

[0161] (8) Z'=n*Z2'+m*Z1', m is an integer greater than or equal to 1, and n is an integer greater than or equal to 1;

[0162] (9) Z'=n*Z2'+m*Z2, m is an integer greater than or equal to 1, and n is an integer greater than or equal to 1;

[0163] (10) Z>Z2;

[0164] (11)Z'>Z2'.

[0165]

[0166] Table 1

[0167] Here, μ represents a value associated with the subcarrier spacing.

[0168] It should be noted that the values ​​of the first parameter (Z) and / or the second parameter (Z') for the tightening value are: the first parameter Z=Z2, and the second parameter Z'=Z2'.

[0169] It should be noted that the CSI report includes a sub-configuration configured with the second configuration information and a sub-configuration configured with the third configuration information, wherein the sub-configuration configured with the third configuration information is associated with a first type of CSI-RS resource. The first type of CSI-RS resource includes one of the following:

[0170] (1) The CSI-RS resource indicated by the second configuration information configured in the sub-configuration with the smallest index in the sub-configuration configured with the second configuration information;

[0171] (2) CSI-RS resources configured by high-level parameters;

[0172] (3) The CSI-RS resource indicated by the second configuration information configured in the sub-configuration of the resource containing the smallest index number in the second configuration information;

[0173] (4) Predefined CSI-RS resources;

[0174] (5) CSI-RS resources indicated by the second configuration information configured in the predefined sub-configuration.

[0175] In some embodiments, in a CSI report configuration, if there is a sub-configuration configured with the second configuration information, there will be no sub-configuration configured with only the third configuration information. In other words, if there is a sub-configuration configured with the second configuration information, each sub-configuration must include the second configuration information.

[0176] It should be noted that the first configuration information, the second configuration information, or the third configuration information configured in different sub-configurations may be the same or different. For example, the first configuration information is configured in both sub-configurations, but the specific parameter values ​​of the first configuration information are different.

[0177] In some embodiments, the CSI report configuration includes one or more sub-configurations, the CSI report configuration is aperiodic, and its associated CSI-RS is aperiodic, and the third time indicated in the DCI that triggers the CSI report configuration must be greater than the sixth threshold. The third time is the time interval between the DCI and the triggered CSI-RS, and the sixth threshold is a positive integer greater than or equal to 1.

[0178] In some embodiments, sub-configurations and shared resources (shared CMR (channel measurement resource)) cannot be configured in a CSI report configuration at the same time. In some embodiments, when one or more sub-configurations are configured in a CSI report configuration, its associated CSI-RS resources will not be configured with a resource pair. In some embodiments, if a sub-configuration and a shared resource are configured in a CSI report configuration at the same time, the configuration of the sub-configuration is ignored. Ignoring the configuration of the sub-configuration means not using the configuration in the sub-configuration for CSI measurement. In some embodiments, if a sub-configuration and a shared resource are configured in a CSI report configuration at the same time, the configuration related to the shared resource is ignored. Ignoring the configuration related to the shared resource means not using the configuration related to the shared resource for CSI measurement. The configuration related to the shared resource includes a shared resource configuration, a CSI-ReportMode configuration, or a resource pair configuration, etc.

[0179] In some embodiments, the codebook subset restriction includes a codebook subset restriction and a codebook subset restriction on i2 (codebooksubsetrestriction-i2).

[0180] In some embodiments, when a CSI report contains multiple sub-CSI reports, and the CSI report is divided into two parts (2 parts) for transmission, then, when the resources are insufficient or the code rate does not meet the conditions, the CSI information of part 2 can be discarded (i.e., not transmitted). The broadband part in part 2 (including the broadband CQI of the second codeword, if present, PMI, if reported, and layer indication, if reported) is discarded in sequence according to the content of the sub-configuration until the resource requirements or code rate restrictions are met. In some embodiments, the content of multiple CSI reports is included on one reporting resource. When it is necessary to discard the broadband part of part 2, the CSI report containing the sub-configuration is discarded according to the sub-configuration. If the resource requirements or code rate restrictions are still not met after all the sub-CSI reports of the sub-configuration are discarded, the broadband parts of all parts 2 of other CSI reports will be discarded together.

[0181] In one embodiment, Figure 4 As shown, a flow chart of a channel state information processing method provided by an embodiment of the present invention is applied to the network device 102. The implementation process of the method may include but is not limited to the following step S410:

[0182] Step S410: sending a high-layer configuration signaling including a CSI report configuration to a user equipment, so that the user equipment generates a sub-CSI report corresponding to at least one sub-configuration in the CSI report configuration, and sends a CSI report including at least one sub-CSI report.

[0183] It should be noted that the high-level configuration signaling includes a CSI report configuration, and the CSI report configuration includes at least one sub-configuration, so that the user equipment generates a sub-CSI report corresponding to the sub-configuration for at least one sub-configuration in the CSI report configuration, and sends a CSI report including at least one sub-CSI report. The specific configuration methods of the high-level configuration signaling, CSI report configuration, sub-configuration, sub-CSI report and CSI report have been specifically described in the above embodiments, and will not be repeated here.

[0184] It should be noted that each sub-configuration has a correspondingly associated channel state information-reference signal CSI-RS resource, and the sub-CSI report corresponding to the sub-configuration is determined according to the first type of parameters and the CSI-RS resource correspondingly associated with the sub-configuration.

[0185] The embodiments of the present invention mainly involve the configuration scheme when reporting multiple sets of CSI information in one CSI report and the time requirements for CSI calculation. Specifically, the user equipment receives high-level configuration signaling, wherein the high-level configuration signaling includes a CSI report configuration, and the CSI report configuration includes at least one sub-configuration. Then, for at least one sub-configuration, a sub-CSI report corresponding to the sub-configuration is generated. The present invention reports multiple sets of CSI information (each set of CSI information corresponds to an antenna shutdown mode or power mode) in one CSI report, which can help the base station obtain the channel status under multiple antenna shutdown modes, so as to better perform data scheduling. Therefore, the present invention can generate a sub-CSI report corresponding to the sub-configuration according to the required sub-configuration, and send a CSI report containing at least one sub-CSI report to the network device, so that the UE can perform CSI measurement and reporting according to different configurations, thereby improving the accuracy and efficiency of data scheduling.
