Abstract

The application provides a method for processing channel state information resources and related devices. In the method, a network device can configure a mechanism for skipping CSI-RS on demand for a terminal device. In the mechanism, the terminal device does not need to measure all received CSI-RS, but can skip the measurement of CSI-RS, that is, no measurement is performed on the skipped CSI-RS, and measurement is performed on the CSI-RS that is not skipped. In this way, while ensuring the utilization rate of CSI-RS resources, more flexible measurement load adjustment can be achieved, and the processing pressure of the terminal device can be effectively alleviated.

Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method and related apparatus for processing channel state information resources. Background Technology

[0002] With the continuous development of wireless communication technology, higher requirements have been placed on system capacity and spectral efficiency. The application of massive multiple input multiple output (MMIMO) technology plays a crucial role in improving the spectral efficiency of the system. To meet the needs of massive MIMO systems for larger antenna arrays, finer beamforming, and higher channel resolution, it is necessary to increase the number of ports supported, enabling terminal devices to receive more CSI-RS signals.

[0003] Due to the limited processing power of terminal devices, but the need to continuously receive, process, and generate multiple CSI-RS messages and CSI reports within a limited timeframe, CSI-RS message backlog and resource conflicts can easily occur, affecting the accuracy and timeliness of CSI reports. Therefore, how to handle multiple CSI-RS messages under the limited processing power of terminal devices is a problem that needs to be considered. Summary of the Invention

[0004] This application provides a method and related apparatus for processing channel state information resources. This method can ensure the utilization rate of CSI-RS resources while enabling more flexible measurement load adjustment, and can effectively alleviate the processing pressure on terminal equipment.

[0005] In a first aspect, embodiments of this application provide a method for processing channel state information resources. This method can be applied to a terminal-side device, which may be a terminal device, a component applied within the terminal device (e.g., a processor, chip, circuit, or chip system), or a logic module or software capable of implementing all or part of the terminal device's functions. The method includes:

[0006] Receive a first message, wherein the first message includes first indication information, the first indication information being used to indicate skipping the measurement of channel state information (CSI) resources, the CSI resources including at least one channel state information reference signal (CSI-RS) of the same type;

[0007] When measuring the CSI resources, a first CSI-RS is measured based on the first indication information and a second CSI-RS is not measured, wherein the first CSI-RS is a CSI-RS that is not skipped among the at least one CSI-RS, and the second CSI-RS is a CSI-RS that is skipped among the at least one Channel State Information Reference Signal CSI-RS;

[0008] Send a first CSI report, wherein the first CSI report includes the measurement results of the first CSI-RS.

[0009] For example, if a CSI-RS of the same type is associated with the same CSI report configuration, then at least one CSI-RS has the same priority.

[0010] It is understandable that when at least one CSI-RS sent from a network device to a terminal device belongs to the same type, at least one CSI-RS has the same priority. That is, in this case, there is no distinction between primary and secondary CSI-RS, and the terminal device processes the received CSI-RS with the same priority, which can easily lead to CSI-RS measurement task stacking. In the above method, this application embodiment provides a skipping mechanism. When measuring at least one CSI-RS resource, the measurement of one of the CSI-RS can be skipped based on this skipping mechanism. That is, the measurement is not performed on the CSI-RS, and the measurement is performed on the CSI-RS that are not skipped. In this way, while ensuring the utilization rate of CSI-RS resources, more flexible measurement load adjustment can be achieved, which can effectively alleviate the processing pressure of the terminal device.

[0011] In one possible implementation of the first aspect, the measurement of the first CSI-RS based on the first indication information and the non-measurement of the second CSI-RS includes:

[0012] The first CSI-RS is measured based on the first indication information and the parallel processing capability of the terminal device, and the second CSI-RS is not measured. The number of the first CSI-RS is less than or equal to the number corresponding to the parallel processing capability, and the number of the second CSI-RS is the number of CSI-RS other than the first CSI-RS among the at least one CSI-RS.

[0013] In the above method, the processing power of the terminal device is limited, that is, the number of CSI-RS that the terminal device can process in parallel is limited. In this case, a skipping mechanism and the parallel processing capability of the terminal device can be combined to skip the measurement of some CSI-RS, that is, not to perform the measurement on them, but to perform the measurement on the CSI-RS that are not skipped. The number of CSI-RS that are not skipped is consistent with the parallel processing capability of the terminal device, which reduces the probability of the terminal device overload and maintains system stability.

[0014] In one possible implementation of the first aspect, the first message further includes second indication information, which indicates a skipping method for the CSI resource.

[0015] In the above method, the network device can configure a skipping mode for the terminal device. Therefore, the terminal device can skip the measurement of a specific CSI-RS according to the configured skipping mode, that is, not measure it, which enhances the flexibility of skipping control and the controllability of measurement scheduling on the network side.

[0016] In one possible implementation of the first aspect, the measurement of the first CSI-RS based on the first indication information and the non-measurement of the second CSI-RS includes:

[0017] Based on the first indication information and the second indication information, the first M CSI-RSs among the at least one CSI-RS are measured, and the CSI-RSs other than the first M CSI-RSs among the at least one CSI-RSs are not measured, where M is an integer greater than or equal to 1.

[0018] In one possible implementation of the first aspect, the measurement of the first CSI-RS based on the first indication information and the non-measurement of the second CSI-RS includes:

[0019] Based on the first indication information and the second indication information, the first CSI-RS is determined to perform the measurement according to the first interval from the at least one CSI-RS, and the second CSI-RS is determined not to perform the measurement.

[0020] In the above methods, network devices can flexibly configure skipping modes according to scheduling policies and service requirements. One mode instructs terminal devices to prioritize processing newly arrived CSI-RS, thereby enabling them to receive and report measurement results as continuously as possible within the processing capacity of the terminal devices. This is suitable for scenarios with higher requirements for CSI report update frequency. Another mode instructs terminal devices to process CSI-RS evenly at intervals, making measurement opportunities more evenly distributed over time. This is more suitable for application scenarios that require stability of measurement rhythm and continuity of reporting.

[0021] In one possible implementation of the first aspect, the first CSI report further includes third indication information, wherein the third indication information is used to indicate that the second CSI-RS is a CSI-RS that was not measured among the at least one CSI-RS.

[0022] In some examples, the second CSI-RS is included after the CSI-RS in the first CSI-RS.

[0023] In some other examples, skipped CSI-RS do not generate CSI-RS reports.

[0024] In the above method, to reduce the probability of the network side misjudging the skipping behavior of the terminal device, the terminal device can carry indication information in the CSI report to indicate the skipped CSI-RS, and further, to indicate in advance whether the next CSI-RS will be skipped. In this way, the network device can determine the processing polarization of the terminal device accordingly, avoiding misinterpreting skipping as channel degradation or terminal anomaly. It can be seen that this predictive feedback mechanism can ensure the transparency and controllability of skipping decisions.

[0025] In one possible implementation of the first aspect, the method further includes:

[0026] Send first capability information, which is used to indicate the processing delay of the terminal device, wherein the time interval between any two adjacent CSI-RS in the at least one CSI-RS is less than or equal to the processing delay.

[0027] The processing latency of the terminal device refers to the time required for the terminal device to receive, process (including measurement), and generate a CSI report.

[0028] In some examples, the time interval between any two adjacent CSI-RS in at least one CSI-RS may be referred to as the configuration period of the CSI-RS.

[0029] In the above method, the terminal device can report its processing latency, so that the network device can enable the CSI-RS skip function for the terminal device if it detects that the CSI-RS configuration period is less than the terminal device's processing latency.

[0030] In one possible implementation of the first aspect, the method further includes:

[0031] When the first indication information is used to indicate that the measurement of the CSI resource is not skipped, the terminal device measures the at least one CSI-RS, and the first CSI report includes the measurement results of the at least one CSI-RS.

[0032] In the above method, the skip function is only enabled when the first indication information indicates that the measurement of CSI resources should be skipped; therefore, if the first indication information does not indicate that the measurement of CSI resources should be skipped, the terminal device will not skip the measurement of CSI resources even if the second indication information exists.

[0033] Secondly, embodiments of this application provide a method for processing channel state information resources. This method can be applied to a network-side device, which may be a network device, a component applied in the network device (e.g., a processor, chip, circuit, or chip system), or a logic module or software capable of implementing all or part of the functions of the network device. The method includes:

[0034] Send a first message, wherein the first message includes first indication information, the first indication information being used to indicate skipping the measurement of CSI resources, the CSI resources including at least one CSI-RS of the same type, wherein the first indication information is used to indicate measuring a first CSI-RS and not measuring a second CSI-RS, the first CSI-RS being the CSI-RS that is not skipped among the at least one CSI-RS, and the second CSI-RS being the CSI-RS that is skipped among the at least one CSI-RS;

[0035] Receive a first CSI report, wherein the first CSI report includes the measurement results of a first CSI-RS.

[0036] In one possible implementation of the second aspect, the number of the first CSI-RS is less than or equal to the number corresponding to the parallel processing capability of the terminal device, and the number of the second CSI-RS is the number of CSI-RS other than the first CSI-RS among the at least one CSI-RS.

[0037] In one possible implementation of the second aspect, the first message further includes second indication information, which indicates the skipping method for the CSI resource.

[0038] In one possible implementation of the second aspect, the second indication information is used to indicate that the first CSI-RS includes the first M CSI-RSs among the at least one CSI-RS, and the second CSI-RS includes the CSI-RSs other than the first M CSI-RSs among the at least one CSI-RS, where M is an integer greater than or equal to 1.

[0039] In one possible implementation of the second aspect, the second indication information is used to indicate the determination of the first CSI-RS that needs to be measured and the second CSI-RS that does not need to be measured from the at least one CSI-RS at a first interval.

[0040] In one possible implementation of the second aspect, the first CSI report further includes third indication information, wherein the third indication information is used to indicate that the second CSI-RS is a CSI-RS that was not measured among the at least one CSI-RS.

[0041] In one possible implementation of the second aspect, the method further includes:

[0042] The terminal device receives first capability information, which is used to indicate the processing delay of the terminal device, wherein the time interval between any two adjacent CSI-RS in the at least one CSI-RS is less than or equal to the processing delay.

[0043] In one possible implementation of the second aspect, where the first indication information is used to indicate that measurements of CSI resources are not skipped, the first CSI report includes the measurement results of the at least one CSI-RS.

[0079] The terms "system" and "network" in this application are used interchangeably. Unless otherwise stated, " / " indicates that the objects before and after are in an "or" relationship; for example, A / B can mean A or B. "And / or" in this application merely describes the relationship between the related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone, where A and B can be singular or plural. Furthermore, in the description of this application, unless otherwise stated, "multiple" means two or more. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, and c can be one or more. Furthermore, to facilitate a clear description of the technical solution of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish between network elements and similar items with essentially the same function. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order, and that the terms "first" and "second" are not necessarily different.

[0080] References such as "in one implementation," "exemplarily," or "in one implementation" as described in this application mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless otherwise specifically emphasized.

[0081] In this application, the terms "information," "signal," "message," "channel," and "singaling" may sometimes be used interchangeably. It should be noted that, without emphasizing their distinction, their intended meanings are consistent. Similarly, the terms "of," "corresponding (relevant)," and "corresponding" may sometimes be used interchangeably. It should be noted that, without emphasizing their distinction, their intended meanings are consistent. Furthermore, the " / " mentioned in this application can be used to indicate an "or" relationship.

[0082] It is understood that in this application, "instruction" can include direct instruction, indirect instruction, explicit instruction, and implicit instruction. When describing a certain instruction information to indicate A, it can be understood that the instruction information carries A, directly indicates A, or indirectly indicates A.

[0083] In this application, the information indicated by the instruction information is called the information to be instructed. In specific implementations, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index; or indirectly indicating the information to be instructed by indicating other information, where there is a relationship between the other information and the information to be instructed; or indicating only a part of the information to be instructed, while the other parts are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various pieces of information, thereby reducing instruction overhead to some extent.

[0084] The information to be instructed can be sent as a whole or divided into multiple sub-information messages, and the sending period and / or timing of these sub-information messages can be the same or different. This application does not limit the specific sending method. The sending period and / or timing of these sub-information messages can be predefined, for example, according to a protocol, or configured by the transmitting device by sending configuration information to the receiving device.

[0085] It is understood that "send" and "receive" in this application refer to the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which can include direct transmission via the air interface or indirect transmission via the air interface from other units or modules. "Receive information from YY" can be understood as the source of the information being YY, which can include direct reception from YY via the air interface or indirect reception from YY via the air interface from other units or modules. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface.

[0086] In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via buses, wiring, or interfaces.

[0087] It is understandable that information may undergo necessary processing, such as encoding and modulation, between the source and destination, but the destination can understand the valid information from the source. Similar statements in this application can be interpreted in a similar way and will not be elaborated further.

[0088] The technical solutions provided in this application can be applied to various communication systems, such as: Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, 5th Generation (5G) systems, or New Radio (NR) systems. In addition, they can also be applied to future communication systems, such as 6th Generation (6G) communication systems.

[0089] The system architecture used in the embodiments of this application is described below. It should be noted that the system architecture and business scenarios described in this application are for the purpose of more clearly illustrating the technical solutions of this application, and do not constitute a limitation on the technical solutions provided in this application. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in this application are also applicable to similar technical problems.

[0090] Please see Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of this application. Figure 1 As shown, the communication system may include a terminal device and a network device. The terminal device and the network device cooperate with each other to implement the method for processing channel state information resources provided in this application.

[0091] In one possible scenario, the terminal device can be a device capable of providing voice and / or data connectivity to the user, such as a terminal equipment, or a functional component within a terminal equipment, such as a chip, chip system, processor, or circuit. The network device can be a device capable of providing wireless communication functionality to the terminal device, such as a network device, or a functional component within a network device, such as a chip, chip system, processor, or circuit.

[0092] Please see Figure 2 , Figure 2 This is a schematic diagram of the architecture of another communication system provided in an embodiment of this application. It should be understood that... Figure 2 The illustration shows a communication system based on machine learning (ML) to which the technical solution provided in this application is applicable. Figure 2 As shown, the communication system includes at least one network device, such as... Figure 2 The network device 110 shown may also include at least one terminal device, such as Figure 2Terminal devices 120 and 130 are shown. Network device 110 can communicate with terminal devices (such as terminal devices 120 and 130) via a wireless link. Communication devices in this communication system, for example, network device 110 and terminal device 120, can communicate using multi-antenna technology.

[0093] In one scenario within a wireless communication network, terminal devices need to feed back channel state information (CSI) to network equipment so that the network equipment can perform precoding and other processing on the downlink data. Typically, the terminal device measures the downlink reference signal (RS) transmitted by the network equipment and calculates downlink channel information (such as the channel matrix) based on the received RS, ultimately generating a CSI report to feed back to the network equipment. The higher the accuracy and the richer the information in the CSI fed back by the terminal device, the more accurate the channel matrix reconstructed by the network equipment based on the fed-back CSI will be. However, as the size of antenna arrays in communication systems increases, the number of supported antenna ports also increases. Since the size of the complete channel matrix is ​​proportional to the number of antenna ports, in large-scale multiple-input multiple-output (MIMO) systems, the terminal device feeding back the complete channel matrix to the base station via CSI incurs significant feedback overhead. Machine learning (ML) methods, with their strong nonlinear feature extraction capabilities, can more effectively extract channel matrix features, thus compressing the CSI information. Therefore, compared to traditional CSI feedback schemes, more channel information can be included in the feedback of the same scale, thereby reducing the information loss of CSI compressed feedback and improving the accuracy of base station channel recovery. In other words, ML-based CSI feedback can represent the same channel information with less feedback compared to traditional schemes, further reducing feedback overhead. Therefore, to support machine learning technology in wireless networks, artificial intelligence (AI) nodes are introduced into the network. Optionally, the communication system also includes an AI network element 140, which is used to perform AI-related operations, such as building training datasets or training AI models.

[0094] In one possible implementation, network device 110 can send data related to the training of the AI ​​model to AI network element 140, which then constructs a training dataset and trains the AI ​​model. For example, the data related to the training of the AI ​​model may include data reported by the terminal device. AI network element 140 can send the results of operations related to the AI ​​model to network device 110, which then forwards them to the terminal device. For example, the results of operations related to the AI ​​model may include at least one of the following: a trained AI model, model evaluation results, or test results. Exemplarily, a portion of the trained AI model may be deployed on network device 110, and another portion on the terminal device. Alternatively, the trained AI model may be deployed on network device 110. Or, the trained AI model may be deployed on the terminal device.

[0095] It should be understood that Figure 2 Taking the direct connection between AI network element 140 and network device 110 as an example, in other scenarios, AI network element 140 can also be connected to a terminal device. Alternatively, AI network element 140 can be connected to both network device 110 and a terminal device simultaneously. Alternatively, AI network element 140 can also be connected to network device 110 through a third-party network element. This application embodiment does not limit the connection relationship between AI network element and other network elements. Figure 2 Taking AI network element 140 as an example as a standalone network element, AI network element 140 can also be configured as a module in network devices and / or terminal devices, for example, configured in... Figure 2 This application does not limit the network device 110 or terminal device shown.

[0096] It should be noted that, Figure 2 This is a simplified illustration for ease of understanding only. For example, the communication system may also include other devices, such as wireless relay devices and / or wireless backhaul devices. Figure 2 The figures are not shown. In practical applications, this communication system may include multiple network devices or multiple terminal devices. This application does not limit the number of network devices and terminal devices included in the communication system.

[0097] It should be understood that Figure 2 The network devices and terminal devices mentioned can be hardware, software based on functional distinctions, or a combination of both. The network devices described above can be any of the network devices described below, and the terminal devices can be any of the terminal devices described below. It should be noted that the methods described in the embodiments of this application can be applied to... Figure 2 The communication system shown.

[0098] (1) Terminal equipment, also known as user equipment (UE), user unit, user station, mobile station (MS), remote station, mobile device, mobile terminal (MT), terminal, wireless communication equipment, etc., is a device that provides voice or data connectivity to users.

[0101] (2) A network device is a device deployed in a wireless access network to provide wireless communication functions for terminal devices. A network device may also be called a wireless access network (RAN) entity, access network equipment, wireless access network device, access node, wireless node, network node, or communication device, etc.

[0102] Network equipment includes, but is not limited to: evolved NodeB (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home-evolved NodeB, or home NodeB, HNB), base band unit (BBU), access point (AP), relay station, macro base station, micro base station, wireless relay node, donor node or similar, or combinations thereof, in Wi-Fi systems; radio controller, wireless backhaul node, transmitting and receiving point (TRP), transmitting point (TP), master station, slave station, motorslide retainer (MSR) node, transmission node, or transceiver node in CRAN scenarios. Network equipment can also be access network equipment in 5G mobile communication systems. For example, a next-generation NodeB (gNB), TRP, TP in a New Radio (NR) system, or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G mobile communication system. Alternatively, network equipment can also be a network node constituting a gNB or transmission point. For example, a central unit (CU), a distributed unit (DU), or a radio unit (RU). Network equipment can also be a baseband unit (BBU), a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). Network equipment can also refer to communication modules, modems, or chips installed within the aforementioned devices or apparatuses. Network equipment can also be a mobile switching center and equipment that performs base station functions in D2D, V2X, and M2M communications, network-side equipment in next-generation communication networks, and equipment that performs base station functions in future communication systems. Network equipment can support networks with the same or different access technologies. Network equipment can also be a server, wearable device, vehicle, or in-vehicle equipment. For example, in V2X technology, network devices can be roadside units (RSUs).

[0103] Network equipment can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move depending on the location of that mobile base station. In other examples, a helicopter or drone can be configured as a device to communicate with another base station.

[0104] In some deployments, the network devices mentioned in the embodiments of this application may be devices including CU, DU, or CU and DU, or devices with control plane CU nodes (central unit-control plane (CU-CP)) and user plane CU nodes (central unit-user plane (CU-UP)) and DU nodes. For example, the network devices may include gNB-CU-CP, gNB-CU-UP, and gNB-DU.

[0105] It should be noted that, in the embodiments of this application, the device used to implement the functions of the network device can be a network device itself; it can also be a device capable of supporting the network device in implementing the functions, such as a chip system, hardware circuit, software module, or hardware circuit plus software module. This device can be installed in the network device or used in conjunction with the network device. In the embodiments of this application, the chip system can be composed of chips or may include chips and other discrete devices. In this embodiment, the device used to implement the functions of the network device is described as a network device, and this does not constitute a limitation on the solutions of the embodiments of this application.

[0106] Optionally, AI nodes can be deployed in one or more of the following locations within a communication system: access network devices, terminal devices, or core network devices, etc. Alternatively, AI nodes can be deployed independently, for example, in a location other than any of the aforementioned devices, such as in the host or cloud server of an over-the-top (OTT) system. AI nodes can communicate with other devices in the communication system, which can be, for example, one or more of the following: network devices, terminal devices, or core network elements, etc. It is understood that this application does not limit the number of AI nodes. For example, when there are multiple AI nodes, they can be divided based on function, such as different AI nodes being responsible for different functions. It is also understood that AI nodes can be independent devices, or integrated into the same device to implement different functions, or they can be network elements in hardware devices, software functions running on dedicated hardware, or virtualized functions instantiated on a platform (e.g., a cloud platform). This application does not limit the specific form of the aforementioned AI nodes. Optionally, an AI node can be an AI network element or an AI module.

[0107] In one implementation, taking an AI module as an example, the AI ​​module is used to implement corresponding AI functions. For instance, one or more AI modules are deployed in different network elements (such as core network equipment, access network equipment, and terminals) in a communication system. The AI ​​modules deployed in different network elements can be the same or different. As another example, the AI ​​module's model can implement different functions based on different parameter configurations. The AI ​​module's model can be configured based on one or more of the following parameters: structural parameters (e.g., at least one of the following: number of neural network layers, neural network width, inter-layer connections, neuron weights, neuron activation function, or bias in the activation function), input parameters (e.g., the type and / or dimension of the input parameters), or output parameters (e.g., the type and / or dimension of the output parameters). The bias in the activation function can also be called the neural network bias. An AI module can have one or more models. A model can infer an output, which includes one or more parameters. The learning, training, or inference processes of different models can be deployed on different nodes or devices, or they can be deployed on the same node or device.

[0108] To facilitate understanding, we will first introduce some technical terms used in this application.

[0109] 1. Antenna ports (P) can be understood as logical ports or virtual ports. Network devices can perform multi-antenna precoding on the codewords of downlink information, mapping the codewords to multiple antenna ports. For example, the number of these multiple antenna ports may differ from the actual number of physical antennas in the network device.

[0110] 2. Physical antenna: This can be understood as a transmitting antenna that can be identified by a receiving device, or a receiving antenna that can be identified by a transmitting device; or, a transmitting antenna or receiving antenna that can be distinguished in space, which can be called a physical antenna.

[0111] 3. CSI-RS Ports: These ports can be used to carry CSI-RS resources. Each CSI-RS port corresponds to one CSI-RS; one CSI-RS can correspond to multiple CSI-RS ports. Different CSI-RS ports can be multiplexed using code division, frequency division, time division, or space division. In one implementation, one CSI-RS can correspond to at least one CSI-RS port, such as 1, 2, 4, or 32, and each CSI-RS port corresponds to a configured time-frequency code resource. Generally, each CSI-RS port occupies a different time-frequency code resource to reduce mutual interference. Each CSI-RS port corresponds to one or more physical antennas of the network device.

[0112] 4. CSI Report Configuration: Network devices can configure CSI report configuration to terminal devices via radio resource control (RRC) signaling. The CSI report configuration specifies the report content, reporting time, etc., for the measured resources (or reference signals). Terminal devices can then send CSI reports back to the network device based on the report configuration. Typically, a network device can configure multiple CSI reports for a terminal device. Furthermore, if the terminal device supports carrier aggregation, different carrier components can each contain their own corresponding report configurations. Therefore, the report configuration generally needs to be uniquely determined using both carrier component indexes and report configuration indexes.

[0113] Each CSI report configuration includes a CSI report config-ID to identify the configuration. Each configuration includes reference signal resources (such as CSI-RS resources) for CSI measurements. For example, the CSI reference signal resource is defined in the frequency domain as a collection of downlink physical resource blocks (PRBs), each PRB containing 12 subcarriers. The frequency domain resources of the CSI reference resource are defined using RBs as the basic unit, with the specific occupied RB range defined by bandwidth and sub-band.

[0114] Furthermore, the CSI report configuration also indicates the type of the corresponding CSI report, such as periodic (P), semi-persistent (SP), or aperiodic (AP) CSI reports. For PCSI report configurations or SP CSI report configurations on the physical uplink control channel (PUCCH), the report configuration includes, but is not limited to: the CSI report's transmission slot offset, period, and the list of occupied PUCCH resources. For SP CSI report configurations on the physical uplink shared channel (PUSCH), the report configuration includes, but is not limited to: the CSI report's transmission slot offset, period, and the list of occupied PUSCH resources. For AP CSI report configurations on the PUSCH, the report configuration includes the CSI report's transmission slot offset and the list of occupied PUSCH resources.

[0115] As an example, "PCSI reporting configuration or SP CSI reporting configuration on the physical uplink control channel (PUCCH)" can be represented as "CSI reporting configuration on P / SP PUCCH". "SP CSI reporting configuration on the physical uplink shared channel (PUSCH)" can be represented as "CSI reporting configuration on SP PUSCH". "AP CSI reporting configuration on PUSCH" can be represented as "CSI reporting configuration on SP PUSCH".

[0116] Furthermore, the association rules between the CSI monitoring report and the CSI report / CSI inference report carrying compressed CSI information in this embodiment are as follows:

[0117] Periodic performance monitoring CSI reports can only be associated with periodic CSI reports;

[0118] Semi-continuous performance monitoring CSI reports are associated with periodic or semi-continuous CSI reports;

[0119] Non-periodic performance monitoring (CSI) reports can be correlated with periodic, semi-continuous, and non-periodic CSI reports.

[0120] 5. CSI reporting and CSI-RS triggering mechanisms: The configuration of CSI-RS measurement resources and the feedback of CSI reports both support three configuration modes: periodic, semi-persistent, and aperiodic. Please refer to Table 1 for the associated constraints and the triggering or activation signaling of CSI reports, as shown below:

[0121] Table 1

[0122]

[0123] Both non-periodic CSI-RS transmission and non-periodic CSI reporting are triggered by downlink control information (DCI).

[0124] For CSI reports carried on a semi-persistent PUSCH, DCI activation or deactivation is achieved by scrambling with the SP-CSI radio network temporary identifier (SP CSI-RNTI).

[0125] For CSI reports carried on semi-persistent PUCCH, activation can be achieved via MAC-CE activation signaling, and deactivation can be achieved via MAC-CE deactivation signaling.

[0126] For semi-persistent CSI-RS, activation can be achieved via MAC-CE activation signaling, and deactivation can be achieved via MAC-CE deactivation signaling.

[0127] For periodic CSI reports and periodic CSI-RS, once network devices configure periodic CSI-RS Resources and P CSI reports via higher-layer signaling (such as RRC signaling), the configuration takes effect immediately and remains in effect until the higher-layer signaling is released (such as RRCrelease). Therefore, the triggering or activation / deactivation signaling can be CSI report configuration signaling. For example... Figure 4 The first signaling in the illustrated embodiment may be CSI report configuration signaling.

[0128] 6. CSI Reference Resources: For a given serving cell, the CSI reference resources are defined as follows:

[0129] In the frequency domain, a CSI reference resource is a collection of downlink physical resource blocks (RBs), each RB containing 12 subcarriers. The frequency domain resources of a CSI reference resource are based on RBs as the basic unit, and the specific range of RBs occupied is defined by bandwidth and sub-band.

[0130] In the time domain, the definition of CSI reference resources is closely related to the timing of CSI report transmission by the terminal device. Its core is to determine the location of the latest downlink CSI-RS resource used for CSI measurement through uplink and downlink time slot mapping and time offset. The time offset ensures that the terminal device has sufficient time to generate a CSI report. The time offset is related to the terminal device's CSI calculation latency requirements or is predefined by the protocol.

[0131] Please refer to Figure 3 , Figure 3 This is a schematic diagram of a CSI-RS resource in the time domain provided in an embodiment of this application. For example... Figure 3 As shown, assume the uplink time slot for the terminal device to send the CSI report is... n Since the mapping relationship between uplink and downlink time slots is related to the uplink and downlink subcarrier space (SCS), for example, when the uplink and downlink subcarrier space (SCS) are the same, the uplink and downlink time slots correspond one-to-one; when the SCS are different, there may be multiple uplink time slots corresponding to one downlink time slot. Therefore, the terminal device can allocate uplink time slots... n ′ is converted to the corresponding downlink time slot n Downlink time slotn Refers to uplink time slots n The corresponding downlink time slots are '' and '', and these two time slots correspond to the same time, namely the transmission time of the CSI report. Furthermore, the terminal device can adjust the time offset configured by the network for preparing the CSI report. n CSI_ref To determine the time-domain location of the CSI reference resource, i.e., from the downlink time slot. n Lean forward n CSI_ref The time-domain location of the CSI reference resource can be obtained; that is, the CSI reference resource is defined as a downlink time slot. n- n CSI_ref .from Figure 3 It can be seen that terminal devices can only use CSI-RS resources with a time domain position no later than that of the CSI reference resource for measurement.

[0132] Understandably, one of the goals of CSI-RS enhancements in 3GPP Release 19 (3GPP R19) is to support, for example, 128 CSI-RS ports to meet the demands of ultra-large-scale MIMO systems for larger antenna arrays, finer beamforming, and higher channel resolution. However, current protocol specifications only support, for example, 32 CSI-RS ports, which is insufficient for future network evolution. Therefore, to achieve support for 128 ports, a systematic enhancement design of the CSI-RS measurement and reporting mechanism is required. According to current solutions, multiple CSI-RS resources can be combined to achieve joint measurement of antenna ports (P) ≤ 128 CSI-RS ports and support hybrid beamforming under multi-beam configurations. Please refer to [link to relevant documentation]. Figure 4 , Figure 4 This is a schematic diagram of joint measurement of multiple CSI-RS resources provided in an embodiment of this application. Figure 4As shown, with 32 antenna ports, these 32 antenna ports are combined into four groups of CSI-RS resources: CSI-RS#0, CSI-RS#1, CSI-RS#2, and CSI-RS#3. Each group of CSI-RS resources corresponds to 32 antenna ports; that is, CSI-RS#0 corresponds to 32 antenna ports, CSI-RS#1 corresponds to 32 antenna ports, CSI-RS#2 corresponds to 32 antenna ports, and CSI-RS#3 corresponds to 32 antenna ports. Therefore, network devices can transmit CSI-RS#0, CSI-RS#1, CSI-RS#2, and CSI-RS#3 through these 32 antenna ports respectively. Finally, by using the joint measurement method of four groups of 32-port CSI-RS resources, the terminal device can receive CSI-RS from 128 CSI-RS ports, thereby measuring the CSI information of 128 CSI-RS ports.

[0133] However, according to the R19 protocol requirements, to ensure that terminal devices have the capability to handle a large number of CSI-RS ports, a capability2 timeline mechanism is introduced for terminal devices. This mechanism requires that the processing latency τ of CSI-RS resources by the terminal device must not be less than a preset time, which can be 10 × 2. μ The symbol time is μ, where μ is the subcarrier spacing, i.e., τ ≥ 10 × 2. μ μ is the subcarrier spacing (SCS), which is measured in kilohertz (kHz). For example, μ=0, SCS=15kHz; μ=1, SCS=30kHz; μ=2, SCS=60kHz.

[0134] In one implementation, to accommodate 128 CSI-RS ports, the mechanism extends the original baseline processing timing Z or Z′ by scaling factor ceil (P / 32) to form the extended capability2 processing timing.

[0135] Here, ceil is the floor function, and P is the number of CSI-RS ports currently configured (e.g., 32 ≤ P ≤ 128). For example, when P ≤ 32, ceil(P / 32) = 1, and the timing remains unchanged; when 33 ≤ P ≤ 64, ceil(P / 32) = 2, and the timing is extended to twice its original value; when 65 ≤ P ≤ 96, ceil(P / 32) = 3, and the timing is extended to three times its original value; when 97 ≤ P ≤ 128, ceil(P / 32) = 4, and the timing is extended to four times its original value.

[0136] Where Z is used for periodic or semi-persistent CSI reports, and Z′ is used for aperiodic reports. Z represents the shortest processing time (in symbols) required from the time the terminal device receives the last symbol of the periodic or semi-persistent CSI-RS until the terminal device is ready to send the corresponding CSI report on its configured Physical Uplink Control Channel (PUCCH). Z′ represents the shortest processing time (in symbols) required from the time the terminal device receives the last symbol of the aperiodic CSI-RS that triggered the report until the terminal device is ready to send the corresponding CSI report on its scheduled Physical Uplink Shared Channel (PUSCH).

[0137] Understandably, to support 128 CSI-RS ports, the terminal device needs either ceil(128 / 32)×Z or ceil(128 / 32)×Z′ time to complete the CSI-RS processing. Because the total processing time increases, the corresponding CSI measurement reference points... n CSI_ref This also needs to be shifted accordingly to allow sufficient processing time for terminal devices.

[0138] To support 128 CSI-RS ports, the above method essentially alleviates the processing pressure caused by the increased number of CSI-RS ports by extending the processing time window. However, this method may result in overlapping CSI-RS processing tasks; please refer to [link to relevant documentation]. Figure 5 , Figure 5 This is a schematic diagram illustrating overlapping CSI-RS processing tasks provided in an embodiment of this application. Figure 5 As shown, taking three sets of CSI-RS resources as an example, these three sets of CSI-RS resources are CSI-RS#1, CSI-RS#2 and CSI-RS#3, and the distribution cycle of these three sets of CSI-RS resources is T. CSI_RS That is, the time interval between CSI-RS#1 and CSI-RS#2 is T. CSI_RS The time interval between CSI-RS#2 and CSI-RS#3 is T. CSI_RS In some scenarios, the CSI-RS resource distribution cycle T CSI_RS Less than the processing latency τ of the terminal device, i.e., T CSI_RS <τ, in this scenario, overlapping CSI-RS measurement tasks may occur. From Figure 5As can be seen, CSI-RS#2 arrives while the terminal device is processing CSI-RS#1 and has not yet completed processing (i.e., CSI report-1 has not yet been sent). In this situation, the terminal device needs to process CSI-RS#2, meaning it needs to process CSI-RS#1 and CSI-RS#2 in parallel. Consequently, CSI-RS#3 arrives while the terminal device is processing CSI-RS#1 and CSI-RS#2 and has not yet completed processing (i.e., CSI report-1 and CSI report-2 have not yet been sent). Due to the limited parallel processing capability of the terminal device, it cannot process CSI-RS#3, resulting in overlapping CSI-RS measurement tasks in time and significantly increasing the processing burden on the terminal device.

[0139] The processing of CSI-RS resources includes receiving CSI-RS, measuring CSI-RS, and generating CSI reports. "CSI-RS resource processing not yet complete" means that the CSI report corresponding to that CSI-RS has not yet been sent.

[0140] It can be seen that when the reporting cycle of CSI reports is set too short, the distribution cycle T of CSI-RS resources is very likely to be delayed. CSI_RS When the processing latency τ of the terminal device is less than that of the terminal device, the terminal device needs to continuously complete the reception, processing, and CSI report generation of multiple CSI-RS resources within a limited time. This can easily lead to processing backlog and resource conflicts, and may even exceed the terminal device's capacity limit, affecting the accuracy and timeliness of the reports. Therefore, when designing a CSI-RS enhancement mechanism that supports 128 ports, it is necessary to comprehensively consider the coordination relationship between the CSI-RS configuration cycle, processing latency, and CSI reporting cycle to avoid configuration conflicts and processing resource bottlenecks. This ensures that the terminal device's capabilities match the system design requirements, thereby fully releasing the performance potential of large-scale MIMO.

[0141] In view of this, embodiments of this application provide a method and related apparatus for measuring channel state information resources, and provide a framework for "on-demand skip measurement", which enables network devices to dynamically issue measurement tasks based on the actual parallel processing capabilities of terminal devices, thereby improving the unified understanding of skip behavior between network devices and terminal devices.

[0142] In the embodiments of this application, CSI-RS can be understood as CSI-RS occasion, that is, CSI-RS resource occasion, which refers to the specific time point (or time window) when the CSI-RS signal is transmitted in the time-frequency domain. That is, CSI-RS and CSI-RS occasion have the same probability and the same meaning. For ease of description, CSI-RS will be used as an example hereafter. CSI-RS can also be replaced by CSI-RS occasion.

[0143] Please see Figure 6 , Figure 6 This is a signaling interaction diagram illustrating a method for processing channel state information resources provided in an embodiment of this application. Figure 6 The method shown can be applied to terminal-side devices and network-side devices. The terminal-side device can be a terminal device, a component applied within the terminal device (e.g., a processor, chip, circuit, or chip system), or a logic module or software capable of implementing all or part of the terminal device's functions. The network-side device can be a network device, a component applied within the network device (e.g., a processor, chip, circuit, or chip system), or a logic module or software capable of implementing all or part of the network device's functions. The following... Figure 6 The embodiments shown are described using terminal-side devices as terminal equipment and network-side devices as network equipment as examples. The method includes, but is not limited to, the following steps:

[0144] Step S601: The network device sends a first message to the terminal device, the first message including first indication information. Accordingly, the terminal device receives the first message.

[0145] The first indication information is used to indicate that the measurement of the CSI resource is skipped, that is, the measurement of the first CSI-RS in the CSI resource is performed, but the measurement of the second CSI-RS in the CSI resource is not performed.

[0146] In one implementation, the first message further includes second indication information. The second indication information indicates the skipping method for CSI resources; that is, based on this skipping method, CSI resources that do not need to be skipped (i.e., the first CSI-RS) and CSI resources that need to be skipped (i.e., the second CSI-RS) can be selected from the CSI resources. For example, CSI resources include at least one CSI-RS of the same type. CSI-RS of the same type refer to CSI-RS that have the same priority and are associated with the same CSI report configuration; that is, there is no hierarchy among these CSI-RSs, and they are processed with the same priority.

[0147] As some examples, the first message can be RRC configuration signaling or RRC reconfiguration signaling. When the network device configures CSI-RS resources and CSI reports via RRC signaling, if the configuration period T of the configured CSI-RS resources is... CSI_RS Less than the processing latency τ of the terminal device, i.e., T CSI_RSIn the case of <τ, at least one of the first indication information and the second indication information may be sent to the terminal device. It is understood that at least one of the first indication information and the second indication information may be carried in the message configuring CSI-RS resources and CSI reports, or the first indication information and the second indication information may be carried in a message following the message configuring CSI-RS resources and CSI reports.

[0148] As another example, before step S601, the network device may send a UE capability enquiry request message to the terminal device. In response to this request message, the terminal device sends UE capability information to the network device. The terminal device's capability information includes, but is not limited to: a list of AI / ML functions or models that the terminal device can support (such as model ID and version), inference capabilities (such as maximum throughput), training capabilities, UE-side additional conditions, etc. UE-side additional conditions include, but are not limited to: processing capabilities (including processing latency τ and parallel processing capabilities), storage and memory, user settings (such as power-saving mode and performance priority), UE-side antenna mapping relationships, UE movement speed, etc.

[0149] Furthermore, after receiving the UE capability information, the network device can determine the terminal device's processing latency τ from the UE capability information, and then, in the configured T... CSI_RS If the value is less than τ, it indicates that the configuration period of CSI-RS resources is shorter than the UE processing latency, further suggesting that the terminal device is highly susceptible to overload. Therefore, the network device can enable a skip function for CSI-RS resources, meaning that the terminal device may skip some CSI-RS resources when measuring them.

[0150] In one implementation, enabling the skip function means configuring a field in the first indication information to 1 or true, where the field can be a skipAllowed field. For example, the skipAllowed field indicates whether the terminal device allows skipping measurements when overloaded. As another example, configuring the skipAllowed field to 0 or false indicates that the skip function is not enabled, meaning the terminal device does not skip measurements of the first CSI-RS when measuring CSI-RS resources.

[0151] In another implementation, the second indication information is specifically used to indicate the CSI-RS that need to be measured (i.e., the first CSI-RS) and the CSI-RS that can be skipped (i.e., the second CSI-RS) within a CSI-RS resource period. For example, the field of the second indication information can be a treatment pattern field, which occupies at least 2 bits, and can be either 2 or 4 bits. The value of the bit corresponds to the skipping method of the CSI-RS resource indicated by the second indication information; for example, a bit value of 1 indicates that the CSI-RS corresponding to that bit is not skipped; a bit value of 0 indicates that the CSI-RS corresponding to that bit is skipped.

[0152] The skipping method for the CSI-RS resources indicated by the second indication information includes at least one of the following:

[0153] Skip Method 1: Prioritize measuring newly arrived CSI-RS. In this method, the second indication information is used to indicate skipping the first M CSI-RS of at least one CSI-RS, and not skipping the CSI-RS other than the first M CSI-RS of at least one CSI-RS, that is, the CSI-RS after the first M CSI-RS, where M is a positive integer greater than or equal to 1.

[0154] For example, suppose the CSI resources include CSI-RS#1, CSI-RS#2, CSI-RS#3, and CSI-RS#4, and their arrival order at the terminal device is: CSI-RS#1, CSI-RS#2, CSI-RS#3, and CSI-RS#4, without skipping CSI-RS#1 and CSI-RS#2, and skipping CSI-RS#3 and CSI-RS#4. In this method, taking four CSI-RS and four bits as an example, the bit value of the second indication information can be 1100. The first bit is 1 indicating that the first arriving CSI-RS is not skipped, the second bit is 1 indicating that the second arriving CSI-RS is not skipped, the third bit is 0 indicating that the third arriving CSI-RS is skipped, and the fourth bit is 0 indicating that the fourth arriving CSI-RS is not skipped. Taking four CSI-RS and two bits as an example, the second indication bit can be 10. The first bit being 1 indicates that the first two arriving CSI-RSs should not be skipped, and the second bit being 0 indicates that the other two CSI-RSs should be skipped. Ultimately, the first CSI-RS includes CSI-RS#1 and CSI-RS#2; the second CSI-RS includes CSI-RS#3 and CSI-RS#4.

[0155] Skip Method 2: Process CSI-RS uniformly at intervals. In this method, the second indication information is used to indicate which CSI-RS need to be measured (i.e., the first CSI-RS) and which CSI-RS can be skipped (i.e., the second CSI-RS) from at least one CSI-RS according to the first interval.

[0156] For example, suppose CSI resources include CSI-RS#1, CSI-RS#2, CSI-RS#3, and CSI-RS#4, and their arrival order at the terminal device is: CSI-RS#1, CSI-RS#2, CSI-RS#3, and CSI-RS#4. We can select CSI-RS#1 and CSI-RS#3, or CSI-RS#2 and CSI-RS#4, using an interval method. It can be seen that when CSI-RS#1 and CSI-RS#3 are selected, there is an interval of CSI-RS#2 between them. When CSI-RS#2 and CSI-RS#4 are selected, there is an interval of CSI-RS#3 between them. In this method, taking four CSI-RS and four bits as an example, the second indication bit value can be 1010, the first bit value of 1 indicates that the first arriving CSI-RS should not be skipped, the second bit value of 0 indicates that the second arriving CSI-RS should be skipped, the third bit value of 1 indicates that the third arriving CSI-RS should not be skipped, and the fourth bit value of 0 indicates that the fourth arriving CSI-RS should not be skipped. Alternatively, the second indication bit value can be 0101, the first bit value of 0 indicates that the first arriving CSI-RS should be skipped, the second bit value of 1 indicates that the second arriving CSI-RS should not be skipped, the third bit value of 0 indicates that the third arriving CSI-RS should be skipped, and the fourth bit value of 1 indicates that the fourth arriving CSI-RS should not be skipped.

[0157] As further examples, the content indicated by the second indication information takes effect when the field of the first indication information is configured to 1 or true. That is, when the field of the first indication information is configured to 1 or true, the second indication information is specifically used to indicate (within a CSI-RS resource period) which CSI-RS need to be measured and which CSI-RS can be skipped. It is understood that when the field of the first indication information is configured to 0 or false, the skipping method of the CSI-RS indicated by the second indication information does not take effect.

[0158] Step S602: When measuring CSI resources, the terminal device measures the first CSI-RS based on the first indication information and does not measure the second CSI-RS.

[0159] Specifically, the network device sends / distributes CSI-RS resources to the terminal device, and the CSI-RS resources include at least one CSI-RS. After receiving the CSI resources, the terminal device, during the process of measuring the CSI-RS resources, may measure a first CSI-RS based on a first indication information and not measure a second CSI-RS. The first CSI-RS is the CSI-RS that is not skipped from the at least one CSI-RS, and the second CSI-RS is the CSI-RS that is skipped from the at least one CSI-RS.

[0160] In one possible implementation, when measuring CSI resources, the terminal device can determine, based on first indication information, that the measurement of CSI-RSs in the CSI resources needs to be skipped. Then, the terminal device can measure the first CSI-RS and not measure the second CSI-RS based on its parallel processing capabilities. That is, the first CSI-RS are the CSI-RS in the CSI resources that are not skipped, and the second CSI-RS are the CSI-RS in the CSI resources that are skipped; the skipped CSI-RS do not participate in the processing. The number of first CSI-RSs is less than or equal to the number corresponding to the parallel processing capability, and the number of second CSI-RSs is the number of CSI-RS other than the first CSI-RS among the at least one CSI-RS. It is understood that the number N of CSI-RS that the terminal device can process in parallel is limited. If the number of CSI-RS exceeds this number N, the terminal device will be unable to process the excess CSI-RS.

[0161] In one implementation, the value of N, the number of CSI-RS that the terminal device can process in parallel, is related to the number of CSI processing units in the terminal device. A CSI processing unit refers to a hardware or software module used for acquiring, estimating, quantizing, compressing, feeding back, or utilizing CSI. The CSI processing unit is used to call the AI ​​model to output inference data. Further, the CSI processing unit includes a first CSI processing unit and a second CSI processing unit, the second CSI processing unit also being referred to as an AI processing unit. Optionally, the first and second CSI processing units can be occupied by different CSI reports. A CSI report can occupy the first CSI processing unit and / or the second CSI processing unit. Optionally, different CSI reports occupy different CSI processing units; for example, the first CSI report occupies CSI processing unit 1 (first CSI unit 1 and / or second CSI unit 1), and the second CSI report occupies CSI processing unit 2 (first CSI unit 2 and / or second CSI unit 2), where CSI processing unit 1 and CSI processing unit 2 are different CSI processing units. As an example, N can be 2.

[0162] Optionally, terminal device processing CSI-RS refers to the terminal device creating a logical entity (i.e., CSI processing unit) on hardware resources to run AI models and be responsible for CSI reporting.

[0163] In another possible implementation, the first message further includes second indication information, allowing the terminal device to measure a first CSI-RS and not measure a second CSI-RS based on the first and second indication information. The second CSI-RS is the CSI-RS that needs to be skipped based on the skipping method indicated by the second indication information, while the first CSI-RS is the CSI-RS that does not need to be skipped based on the skipping method indicated by the second indication information.

[0164] As some examples, network devices configure CSI-RS resources according to the configuration period T. CSI_RS During the CSI-RS distribution process, after receiving the CSI-RS, the terminal device can make the following judgment: If the skipAllowed field of the first indication information is TRUE or 1 and the treatPattern field of the second indication information is not configured (empty in this case can be considered as not configured), the terminal device needs to monitor the number of CSI-RS currently being processed in real time. If the number of CSI-RS (Q) exceeds the number N corresponding to its parallel processing capacity, then CSI-RS exceeding the processing capacity can be skipped according to the first-in-first-out (FIFO) principle, and the skipped CSI-RS are marked as skipped. For example, the third indication information is used to indicate the CSI-RS marked as skipped. In one implementation, the field of the third indication information is a skip bitmap, which is used to indicate that the marked CSI-RS is skipped. For example, a bit value of 1 in the skip bitmap indicates skipping; a bit value of 1 in the skip bitmap indicates measurement.

[0165] When the skipAllowed field of the first indication information is TRUE or 1 and the treatPattern field of the second indication information is configured, the terminal device can process the CSI-RS according to the skipping method indicated by the treatPattern field of the second indication information, that is, according to the corresponding bit of the current CSI-RS in the treatPattern field. If the corresponding bit is 1, the CSI-RS is not skipped and measurement is performed on the CSI-RS; if the corresponding bit is 0, the CSI-RS is skipped and measurement is not performed on the CSI-RS, and the skipped CSI-RS is marked by the third indication information. In this case, the terminal device does not need to determine whether there is a conflict, because the network device has avoided overload scheduling of measurement resources through the preset second indication information.

[0166] When the skipAllowed field of the first instruction message is FALSE or 0, regardless of whether the treatPattern field of the second instruction message is configured, the terminal device needs to process all arriving CSI-RS and queue them for measurement in FIFO order.

[0167] Step S603: The terminal device sends a first CSI report to the network device. The first CSI report includes the measurement results of the first CSI-RS. Accordingly, the network device receives the first CSI report.

[0168] Specifically, the first CSI report includes downlink channel status information fed back by the terminal device to the network device. This status information may include at least one of the following: the measurement results of the first CSI-RS, the AI-based CSI compression results, and the AI-based CSI prediction results, etc.

[0169] In some examples, to reduce the network device's misjudgment of the terminal device's skipping behavior (i.e., skipping the behavior of the second CSI-RS not being measured), the terminal device carries third indication information in the first CSI report. The third indication information is used to indicate that the second CSI-RS is at least one CSI-RS that has not been measured. That is, after receiving the first CSI report, the network device can determine, based on the third indication information in the first CSI report, that there is a CSI-RS (i.e., the second CSI-RS) in the CSI-RS resource that has not performed a measurement.

[0170] In one implementation, the first CSI-RS includes CSI-RS#1, and the second CSI-RS includes CSI-RS#2. In the time domain, CSI-RS#2 is the CSI-RS following CSI-RS#1. The first CSI report includes the processing result of CSI-RS#1 and third indication information indicating that CSI-RS#2 is a skipped CSI-RS for which no measurement was performed. Therefore, when the network device receives the first CSI report, it can know in advance that the next CSI-RS is a skipped CSI-RS.

[0171] In this way, network devices can determine the actual processing polarization of terminal devices, avoiding misinterpreting skipping behavior as channel degradation or anomalies. This predictive feedback mechanism ensures the transparency and controllability of skipping decisions; skipped CSI-RS do not generate CSI reports, achieving silent processing. Upon resuming measurement, the terminal device continues to report normally, reflecting the latest skipping status in the skipBitmap of the third indication information, maintaining logical consistency in the reporting sequence. When receiving CSI reports, network devices can accurately assess measurement coverage by combining the skipBitmap information, and can also adjust subsequent CSI-RS delivery and resource scheduling strategies based on the actual load of the terminal devices.

[0172] Example 1: This example illustrates the second skip method indicated by the second instruction message.

[0173] In skip mode 2: the scenario settings are as follows: subcarrier spacing μ=1 (corresponding to SCS=30kHz), CSI-RS processing delay is 20 slots, and CSI-RS period T CSI_RS =5 slots, the maximum parallel processing capacity of the terminal device is 2 (i.e., maxConcurrentCSI-RS-Measurement=2), and the system uses the same CSI-RS resource to associate the same CSI report configuration. Please refer to Figure 7A , Figure 7A This is a schematic diagram of a measurement schedule for skipping mode one provided in an embodiment of this application. The network device anticipates that this period setting may cause overlap in CSI-RS measurement / processing tasks. Based on the capability information reported by the terminal device, it initiates a skipping mechanism in the RRC (i.e., skipAllowed=TRUE) and configures the processing mode treatPattern=1010 in the second indication information to meet the requirement for stable CSI reporting.

[0174] from Figure 7AAs can be seen, under this configuration, the network device periodically allocates CSI-RS resources every 5 slots. The terminal device, based on the `treatPattern` setting, processes CSI-RS#1 (i.e., the CSI-RS corresponding to CSI-RS index 1) and CSI-RS#3, skips CSI-RS#2 and CSI-RS#4, and marks the skipped CSI-RSs (i.e., CSI-RS#2 and CSI-RS#4) locally as Skipped. Subsequently, in the CSI report corresponding to at least one of CSI-RSs (CSI-RS#1 and CSI-RS#3), the network device informs the network device in advance of its skipping behavior for CSI-RS#2 and CSI-RS#4 through the `skipBitmap` field (its bit value is 0101). The terminal device will not generate CSI reports for the skipped CSI-RS#2 and CSI-RS#4, thus avoiding wasted processing resources.

[0175] When a network device receives a CSI report containing a skipBitmap (such as from CSI-RS#1), it can identify that the terminal device skipped CSI measurements and reporting via CSI-RS#2 and CSI-RS#4. Therefore, even if the CSI reports corresponding to these CSI-RSs are not received, it will not be misjudged as a terminal device losing connection or a channel abnormality, but rather identified as "expected skipping" behavior.

[0176] Example 2: This example illustrates how to skip without configuring a second instruction.

[0177] Without configuring the second indication information, the scenario settings are as follows: subcarrier spacing μ=1 (corresponding to SCS=30kHz), CSI-RS processing delay is 20 slots, and CSI-RS period T. CSI_RS =5 slots, the maximum parallel processing capacity of the terminal device is 2 (i.e., maxConcurrentCSI-RS-Measurement=2), and the system uses the same CSI-RS resource to associate the same CSI report configuration. Please refer to Figure 7B , Figure 7B This is a schematic diagram of a measurement schedule without configuring second indication information, provided in an embodiment of this application. The network device anticipates that this period setting may cause overlap in CSI-RS measurement / processing tasks, and based on the capability information reported by the terminal device, initiates a skip mechanism (i.e., skipAllowed=TRUE) in the RRC, without configuring the processing mode treatPattern.

[0178] from Figure 7BAs can be seen, under this configuration, the network device periodically distributes CSI-RS resources every 5 slots. Without a configured treatPattern, the terminal device dynamically determines whether measurement overlap exists based on its maximum parallel processing capacity (e.g., N=2). After processing CSI-RS#1 (i.e., the CSI-RS corresponding to CSI-RS index 1) and CSI-RS#2, the terminal device detects that CSI-RS#3 and CSI-RS#4 exceed its processing capacity upon receiving them, and since skipAllowed is set to TRUE, it chooses to skip CSI-RS#3 and CSI-RS#4 and marks them as Skipped locally. Subsequently, in the CSI report corresponding to at least one of the CSI-RS in CSI-RS#1 and CSI-RS#2, the network device informs the network device in advance of its skipping behavior for CSI-RS#3 and CSI-RS#4 through the skipBitmap field (its bit value is 0011). Terminal devices will not generate CSI reports for skipped CSI-RS#3 and CSI-RS#4, thereby reducing processing burden and saving resource overhead.

[0179] When a network device receives a CSI report containing a skipBitmap (such as from CSI-RS#1), it can identify that the terminal device skipped CSI measurements and reporting via CSI-RS#3 and CSI-RS#4. Therefore, even if the CSI reports corresponding to these CSI-RSs are not received, it will not be misjudged as a terminal device disconnection or channel abnormality, but rather identified as "expected skipping" behavior.

[0180] Please see Figure 8 , Figure 8 This is a flowchart illustrating a method for processing channel state information provided in an embodiment of this application. Figure 8 As shown, the method includes, but is not limited to, the following steps:

[0181] Step S1: Capability declaration of the terminal device.

[0182] For example, in the capability declaration of the terminal device, the terminal device reports the processing latency τ and the parallel processing capability N to the network device.

[0183] Step S2: Configure the network device for RRS.

[0184] For example, network devices can configure CSI-RS resources and CSI reports via RRC signaling, with the configuration period T for the configured CSI-RS resources. CSI_RS Less than the processing latency τ of the terminal device. In the configured T... CSI_RSIf the period is less than τ (i.e., the period is shorter than the UE processing latency), the skip function can be enabled for this resource: skipAllowed – TRUE / FALSE, indicating whether the terminal device allows skipping measurements when overloaded; treatPattern – optional configuration (such as “1100” or “1010”), which only takes effect when skipAllowed=TRUE, defining which CSI-RS need to be measured or can be skipped within a period.

[0185] Step S3: The network device issues CSI-RS.

[0186] For example, the network device can configure the network according to the configuration period T. CSI_RS Issue CSI-RS.

[0187] Step S4: The terminal device executes CSI-RS measurement and skip logic.

[0188] For example, the terminal device measures the first CSI-RS and does not measure the second CSI-RS according to the CSI-RS measurement and skip logic configured in the RRC configuration.

[0189] Step S5: Predictive skip feedback mechanism for terminal devices.

[0190] For example, the terminal device marks the skipped second CSI-RS as Skipped.

[0191] Step S6: The terminal device collaboratively skips the feedback mechanism to generate and send a CSI report.

[0192] For example, the CSI report includes third indication information, which is used to indicate a skipped second CSI-RS.

[0193] Step S7: The network device identifies the behavior of the terminal device skipping the CSI report.

[0194] For example, the network device identifies the behavior of the terminal device skipping the measurement of the second CSI-RS without generating a CSI report based on the third indication information carried in the CSI report.
