As another example, the wireless terminal may be a device such as a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), etc. The wireless terminal may be called a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, a remote terminal, an access terminal, a user terminal, a user agent, a user device or a user equipment, and is not limited thereto. Optionally, the above terminal 101 may be a device such as a smart watch, a tablet computer, etc.

[0082] The network device 102 may be a base station. Specifically, it may be a base transceiver station (BTS) and / or a base station controller in a global system of mobile communication (GSM) or code division multiple access (CDMA), a base station (NodeB, NB) and / or a radio network controller (Radio Network Controller, RNC) in a wideband code division multiple access (WCDMA), an evolutional Node B (eNB or eNodeB), a relay station or an access point in a long term evolution (LTE), or a base station (gNB) in a future 5G network. The network device 102 in FIG. 1 is exemplified as a base station, but the embodiment of the present disclosure is not limited thereto.

[0083] In the field of wireless communication, Channel State Information (CSI) is a channel attribute of a communication link, which describes the attenuation factor of the signal in each transmission path; CSI enables the communication system to adapt to the current channel conditions, ensuring reliable and high-rate communication in multi-antenna systems; channel conditions play a crucial role in wireless communication, making it necessary to usually feed back CSI in practical wireless communication systems.

[0084] In the related art, there are various methods for obtaining CSI. For example, CSI is obtained based on 3GPP Type I codebook, and CSI is obtained based on 3GPP Type II codebook. In recent years, some literatures have proposed obtaining CSI based on artificial intelligence (AI) technology. The AI ​​technology includes, but is not limited to, one or more of neural network technology, machine learning technology, encoding technology, model training technology, data-driven technology, etc. Taking the CSI feedback based on encoding technology as an example, it can be realized using a self-encoder network composed of two parts, an encoder and a decoder, where the encoder is used to compress input data based on AI technology, and the decoder is used to reconstruct the input based on the compression result.

[0085] Illustratively, FIG. 2 is a configuration diagram of a self-encoder provided by an embodiment of the present disclosure. As shown in FIG. 2, input data X is first compressed to Z=f(X) through an encoder, and then the encoded feature Z is decoded to

[0086] However, due to the complexity and change of wireless communication systems, it cannot be guaranteed that a terminal will always have good performance based on one CSI feedback method; if this feedback method is not applicable to the current channel conditions, the terminal 101 will still perform CSI feedback based on this feedback method, which will cause the network device 102 to obtain incorrect CSI, and further affect the performance of downlink transmission.

[0087] Therefore, the embodiments of the present disclosure provide a method, apparatus, device, and storage medium for processing CSI, in which the terminal 101 processes the CSI input according to the above method, obtains the CSI output, and then sets an evaluation mechanism to first evaluate the CSI output according to the CSI input, and then determine a CSI feedback operation according to the evaluation situation. In this manner, a differentiated CSI feedback operation can be performed according to the current channel condition, so as to improve the reliability of the CSI feedback and ensure the transmission performance of the system.

[0088] Note that Figure 1 above is schematic, and the above scene may include other network devices and terminals, for example, wireless relay devices and wireless forwarding devices (not shown in Figure 1), and while the above scene shows only one terminal 101 and network device 102, the present invention is not limited to this.

[0089] In addition, the technical solutions provided by the embodiments of the present disclosure can be applied to various systems, particularly 5G systems, 6G systems, and their evolution systems. For example, applicable systems include a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA), a general packet radio service (GPRS) system, a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, a long term evolution advanced (LTE-A) system, a universal mobile telecommunication system (UMTS), a worldwide interoperability for microwave access (WiMAX) system, and a 5G new radio (NR) system. Many of these systems all include a terminal and a network device. The system also includes core network parts such as the Evolved Packet System (EPS), 5G System (5GS), and 5G Advanced System.

[0090] Here, a communication system to which the technical solutions provided by the embodiments of the present disclosure can be applied includes a network device and a terminal, where the network device may include an access network device, such as a radio access network device, and a core network device.

[0091] In addition, the method and apparatus provided in the embodiments of the present disclosure are based on the same application concept, and the principles by which the method and apparatus solve the problems are similar, so the implementations of the apparatus and method can refer to each other, and the overlapping points will not be further described.

[0092] Hereinafter, the technical solutions of the embodiments of the present disclosure and how the technical solutions of the embodiments of the present disclosure solve the above technical problems will be described in detail based on specific examples. Some of the following specific examples can be combined with each other, and the same or similar concepts or processes may not be further described in some examples.

[0093] 3 is a schematic diagram 1 of signaling interactions of a method for processing CSI provided by one embodiment of the present disclosure. As shown in FIG. 3, the method for processing CSI includes the following steps:

[0094] S301, a network device sends a CSI feedback indication to a terminal.

[0095] S302, in response to receiving the CSI feedback indication, the terminal sends first feedback information to the network device.

[0096] Here, the first feedback information is information indicating how to obtain CSI feedback information; Or, information indicating the accuracy of the CSI feedback information, or information indicative of first consistency information between the channel-related information and the first information; or information indicative of second consistency information between the channel-related information and the first CSI; Or, information indicating whether CSI feedback information has been transmitted; Includes at least one of the following.

[0097] Here, the information for indicating the first consistency information between the channel-related information and the first information may be the first consistency information itself or a quantized value corresponding to the first consistency information. Similarly, the information for indicating the second consistency information between the channel-related information and the first CSI may be the second consistency information itself or a quantized value corresponding to the second consistency information.

[0098] S303, the network device obtains first feedback information corresponding to the CSI feedback indication.

[0099] Note that the embodiment of the present disclosure does not particularly limit the type of channel-related information. Exemplarily, the channel-related information may be a downlink channel that the terminal obtains based on a downlink signal (e.g., a Channel State Information Reference Signal (CSI-RS) or a Synchronization Signal / PBCH Block (SSB)). Here, PBCH is a Physical Broadcasting Channel.

[0100] In some possible embodiments, the channel related information may be channel information obtained by pre-processing a downlink channel; this is, The channel after time domain clipping, Or, the channel and the terminal after extracting the characteristics of the downlink channel / or Channel characteristics, or a channel feature vector, for example a channel feature vector obtained by performing singular value decomposition on the channel via a method for obtaining the channel feature vector; or channel amplitude features and / or channel phase features; Or at least one of, but not limited to, time domain characteristics of the channel and / or frequency domain characteristics of the channel and / or spatial domain characteristics of the channel.

[0101] It should be understood that the downlink channel as described above may be a channel estimate obtained by the terminal based on the downlink signal.

[0102] In some optional embodiments, the CSI feedback information is determined based on the channel related information and / or the first information, where the first information is obtained by processing the second CSI using a second method corresponding to the first method, the second CSI is obtained by processing the channel related information using the first method, and the first CSI is obtained by processing the channel related information using a third method.

[0103] Here, the first method includes at least one of a data-driven technique and an AI technique (also may be referred to as a neural network technique, a data training technique, a machine learning technique, an encoding technique, and a model training technique), but is not limited to these.

[0104] In the embodiment of the present disclosure, the first method and the second method have a correspondence relationship. For example, when acquiring CSI using the first method is acquiring CSI using an encoder based on the AI, processing the second CSI using a second method corresponding to the first method is specifically processing the second CSI based on a decoder corresponding to the encoder. Furthermore, for example, when acquiring CSI using the first method is acquiring CSI based on a compressed sensing technique, processing the second CSI using a second method corresponding to the first method is specifically processing the second CSI using a CSI recovery algorithm corresponding to the compressed sensing technique corresponding to the first method. The embodiment of the present disclosure does not specifically limit the specific types of the first method and the second method, and the specific type of the third method. Illustratively, the third method may be a codebook-based method, such as a Type I codebook-based method or a Type II codebook-based method. Optionally, the third method is an AI-based method different from the first method. For example, the third method and the first method are different AI algorithms or different parameters.

[0105] In some optional embodiments, the network device may acquire the CSI of the terminal based on different methods based on the contents indicated in the first feedback information, and specific methods for the network device to acquire the CSI are shown in subsequent examples.

[0106] In an embodiment of the present disclosure, when a terminal receives a CSI feedback instruction from a network device, the terminal sends first feedback information to the network device, thereby notifying the network device of a current CSI feedback status through the first feedback information, and the network device uses different methods to differentiate and obtain CSI based on the first feedback information, further improving the reliability of the CSI feedback and ensuring the transmission performance of the system.

[0107] In some embodiments, the first feedback information is obtained based on at least one of the CSI feedback information, the accuracy of the CSI feedback information, the first consistency information, the second consistency information, and whether the CSI feedback information has been transmitted, and a method for obtaining the CSI feedback information is provided in subsequent embodiments.

[0108] In some possible embodiments, the transmission status of the CSI feedback information may be indicated by a signal transmission status on a resource for transmitting the first feedback information. Illustratively, the first feedback information may be characterized without signal transmission on the resource to indicate that the CSI feedback information is not transmitted, and the first feedback information may be characterized with signal transmission on the resource to indicate that the CSI feedback information is transmitted. That is, in the embodiment of the present disclosure, when the network device receives a resource for transmitting the first feedback information, if it determines that there is no signal transmission on this resource, it indicates that the terminal is not currently transmitting CSI feedback information, while if it determines that there is signal transmission on this resource, it indicates that the terminal is currently transmitting CSI feedback information to the network device. The embodiment of the present disclosure does not particularly limit how the network device determines that there is no signal transmission on this resource.

[0109] In some possible examples, the network device may also measure the received power at the resource and determine whether there is a signal transmission based on the received power, specifically, if the received power is less than a certain threshold, there is considered to be no signal transmission.

[0110] Further, for example, the network device may check the signal on the resource and determine whether there is a signal transmission based on the check result. Illustratively, the network device may perform a CRC (Cyclic Redundancy Check) check on the signal on the resource. ofIf the check does not pass, it is assumed that there is no signal transmission, and it is to be noted that the embodiment of the present disclosure is not particularly limited with respect to the magnitude of the threshold.

[0111] In some embodiments, when it is determined that CSI feedback information needs to be sent to the network device, the CSI feedback information may also be sent to the network device. Next, a method for obtaining CSI feedback information will be described in detail with reference to the embodiments shown in Fig. 4. Fig. 4 is a schematic diagram 2 of signaling interactions of a method for processing CSI provided by an embodiment of the present disclosure. As shown in Fig. 4, the method for processing CSI includes the following steps:

[0112] S401, a network device sends a CSI feedback indication to a terminal.

[0113] S402, in response to receiving a CSI feedback indication sent from the network device, the terminal determines a second CSI based on channel-related information.

[0114] Taking the first method as an example that it is an encoding technique, in the embodiment of the present disclosure, the channel-related information can be input into a pre-trained encoder to obtain the second CSI.

[0115] In some optional embodiments, other modules, such as a quantizer, a channel pre-processing module, etc., may be used to process the channel-related information. Here, the channel pre-processing module is used to trim or feature the channel-related information. Note that, for a specific method of obtaining the second CSI based on the encoding technique, reference may be made to the prior art, and detailed description thereof will be omitted here.

[0116] S403, the terminal evaluates the second CSI and obtains CSI feedback information and / or first feedback information.

[0117] It should be understood that there are various evaluation methods for evaluating the second CSI, and the embodiment of the present disclosure is not particularly limited. For example, in one embodiment, the second CSI can be evaluated using a neural network model.

[0118] In another aspect, the acquired second CSI may be processed using a second method corresponding to the first method, and the processing result may be compared with the channel-related information, thereby obtaining an evaluation result of the second CSI based on the consistency between the processing result and the channel-related information. Illustratively, the higher the consistency between the processing result and the channel-related information, the higher the accuracy of the second CSI; on the other hand, the lower the consistency between the processing result and the channel-related information, the lower the accuracy of the second CSI; a specific evaluation method will be described in the following embodiment. Note that the acquired CSI feedback information is different according to the evaluation result. Illustratively, when the accuracy of the second CSI is high, the second CSI may be included in the CSI feedback information, and optionally, the first feedback information may be used to indicate that the current CSI feedback information is acquired using the first method.

[0119] On the other hand, when the accuracy of the second CSI is low, the CSI feedback information may not be sent to the network device, and first feedback information may be sent to the network device to indicate that the CSI feedback information has not been transmitted, or the CSI feedback information may be sent to the network device and then first feedback information may be sent to the network device to indicate the accuracy of the CSI feedback information, or the first CSI obtained by processing the channel-related information using the third method may be sent to the network device. Specific methods for determining the CSI feedback information and the first feedback information will be described in subsequent embodiments.

[0120] S404, the terminal sends CSI feedback information and / or first feedback information to the network device.

[0121] S405, the network device determines the CSI based on the CSI feedback information and / or the first feedback information.

[0122] Accordingly, after receiving the CSI feedback information and / or the first feedback information, the network device may determine, based on the first feedback information, how to obtain the CSI.

[0123] Exemplarily, when the first feedback information is used to indicate that the accuracy of the CSI feedback information is high, it is determined that the CSI feedback information is the final CSI.When the first feedback information is used to indicate that the accuracy of the CSI feedback information is low, it is not necessary to acquire the CSI feedback information, or the CSI feedback information is acquired and calibrated to acquire the CSI.

[0124] Alternatively, when the first feedback information is used to indicate a method for obtaining CSI feedback information, the CSI may be obtained based on this obtaining method.

[0125] In some optional embodiments, when the first feedback information is used to indicate that the CSI feedback information is not transmitted, the CSI feedback information is not acquired, and optionally, the network device may acquire the CSI based on other methods. For example, the network device may use the CSI previously fed back by the terminal as the current CSI. For further example, the network device may process the CSI fed back by the terminal at a past time to acquire the current CSI, and the specific processing method includes, but is not limited to, based on channel prediction, channel difference value, etc., and the present embodiment is not limited thereto.

[0126] In an embodiment of the present disclosure, after the terminal determines the second CSI based on the channel-related information, it first evaluates the second CSI, and then determines the CSI feedback operation based on the evaluation status, thereby performing differentiated CSI feedback based on the current channel condition, improving the reliability of the CSI feedback, and further ensuring the transmission performance of the system.

[0127] Next, an embodiment in which the first CSI is evaluated in the above S403 will be described in detail with reference to a specific example.

[0128] In the first alternative evaluation method, FIG. 5 is a flowchart 1 of a CSI evaluation method provided by an embodiment of the present disclosure. Note that the execution subject of this embodiment may be a terminal in the above scene. As shown in FIG. 5, this CSI evaluation process may include the following steps:

[0129] S501, process channel-related information using a first method to obtain a second CSI.

[0130] S502, processing the second CSI using a second method corresponding to the first method to obtain first information.

[0131] S503, determining CSI feedback information and / or first feedback information based on the channel related information and / or the first information.

[0132] Regarding the specific types of the first method and the second method, and the processing procedures using the first method and the second method, reference can be made to the above embodiments, and no further description will be given here.

[0133] Fig. 6(a) is a principle schematic diagram 1 of a CSI estimation method provided by an embodiment of the present disclosure. As shown in Fig. 6(a), in a first alternative embodiment, the estimation of the second CSI can be realized based on the first consistency information between the channel-related information and the first information, and the CSI feedback information and / or the first feedback information can be determined.

[0134] Specifically, the above step S503 includes the following steps.

[0135] (1) Obtain first consistency information between the channel-related information and the first information.

[0136] (2) determining CSI feedback information and / or first feedback information based on the first consistency information;

[0137] Here, when determining the CSI feedback information and / or the first feedback information based on the first consistency information, specifically, the method includes determining whether the CSI feedback information includes the first CSI and / or the second CSI based on the first consistency information.

[0138] In some alternative embodiments, the information indicative of the first consistency information between the channel-related information and the first information may be the first consistency information itself.

[0139] Here, the first consistency information includes first similarity information and / or first error information between the channel related information and the first information, the first similarity may be a cosine similarity between the channel related information and the first information, and the first error information may be a normalized mean square error (NMSE) or a mean square error (MSE) between the channel related information and the first information. M SE).

[0140] Specifically, when determining the CSI feedback information, any one or more of the following may be included, but are not limited to:

[0141] (1) Determining that the CSI feedback information includes a second CSI if a first condition is satisfied, the first condition including at least that a value of the first consistency information falls within a first range.

[0142] (2) Determining that the CSI feedback information includes a first CSI if a second condition is satisfied, the second condition including at least that a value of the first consistency information falls within a second range.

[0143] (3) determining that the CSI feedback information includes a first CSI and a second CSI if a third condition is satisfied, the third condition including at least that a value of the first consistency information falls within a third range.

[0144] It should be understood that different types of first consistency information correspond to different conditions. Next, a method for determining CSI feedback information will be described by taking the first consistency information as first similarity information and first error information as examples.

[0145] In the embodiment of the present disclosure, the specific values ​​of the first range and the second range are not specifically limited.

[0146] In a first example, when the first consistency information is first similarity information between the channel-related information and the first information, the first similarity is taken as an example of cosine similarity, and first, the value ρ1 of the first similarity information is obtained based on the following equation (1).

[0147] Where:

[0148] Exemplarily, the cosine similarity may be a generalized cosine similarity (GCS) or a squared cosine similarity (SGCS).

[0155] As an alternative embodiment, a range to which the value ρ1 of the first consistency information belongs is determined, and a currently satisfied condition is determined based on the range ρ1 belongs to. It is to be noted that when the first consistency information is the first similarity information, the larger the value of the first similarity information, the higher the similarity between the channel-related information and the first information, and the better the performance of the CSI feedback using the first method.

[0156] For example, a first threshold R1 and a second threshold R2 may be preset, with a first range being a value range greater than R1, a second range being a value range less than R2, and a third range being a value range less than R1 and greater than R2, where R1 is greater than or equal to R2.

[0157] In addition, the first range, the second range, and the third range may be set according to demand. Although the above example is not limiting, for example, the first range may be set to the marking portion equal to or greater than R1, or the second range may be set to the marking portion equal to or less than R2, and they will not be listed here one by one.

[0158] In an embodiment of the present disclosure, in a first aspect, if it is determined that the value ρ1 of the first consistency information is greater than R1 (i.e., the first condition is satisfied), it is determined that the similarity between the channel-related information and the first information is high, i.e., the performance of the CSI feedback using the first method is good, and in this case, it is determined that the second CSI is included in the CSI feedback information.

[0159] In the second aspect, if it is determined that the value ρ1 of the first consistency information is smaller than R2 (i.e., the second condition is satisfied), it is determined that the similarity between the channel-related information and the first information is low, i.e., the performance of the CSI feedback using the first method is poor, and in this case, it is determined that the first CSI is included in the CSI feedback information.

[0160] In a third aspect, if it is determined that the value ρ1 of the first consistency information is smaller than R1 and larger than R2 (i.e., the third condition is satisfied), it is determined that the similarity between the channel related information and the first information is medium, i.e., the performance of the CSI feedback using the first method is medium, and in this case, it is determined that the CSI feedback information includes the first CSI and the second CSI.

[0161] In a second example, when the first consistency information is a first error information between the channel related information and the first information, blood Channel related information and the first information is calculated as a normalized mean square error (NMSE) or a mean square error (MSE), thereby obtaining a first error information value γ1.

[0162] As an alternative embodiment, determine a range to which γ1 belongs, and determine a currently satisfied condition based on the range to which γ1 belongs. It is to be noted that when the first consistency information is first error information, the smaller the value of the first error information, the higher the similarity between the channel-related information and the first information, and the better the performance of CSI feedback using the first method.

[0163] For example, a third threshold R3 and a fourth threshold R4 may be preset, with a first range being a value range smaller than R4, a second range being a value range larger than R3, and a third range being a value range smaller than R3 and larger than R4, where R3 is equal to or greater than R4.

[0164] In addition, the first range, the second range, and the third range may be set according to demand. Although the above example is not limiting, for example, the first range may be set to the marking portion below R4, or the second range may be set to the marking portion above R3, and they will not be listed here one by one.

[0165] In an embodiment of the present disclosure, in a first aspect, if it is determined that the value γ1 of the first error information is smaller than R4 (i.e., the first condition is satisfied), it is determined that the similarity between the channel-related information and the first information is high, i.e., the performance of the CSI feedback using the first method is good, and in this case, it is determined that the second CSI is included in the CSI feedback information.

[0166] In the second aspect, if it is determined that the value γ1 of the first error information is greater than R3 (i.e., the second condition is satisfied), it is determined that the similarity between the channel-related information and the first information is low, i.e., the performance of the CSI feedback using the first method is poor, and in this case, it is determined that the first CSI is included in the CSI feedback information.

[0167] In the third embodiment, the value γ1 of the first error information is RIf it is determined that R is smaller than 3 and larger than R4 (i.e., the third condition is satisfied), it is determined that the similarity between the channel-related information and the first information is medium, i.e., the performance of the CSI feedback using the first method is medium, and in this case, it is determined that the CSI feedback information includes the first CSI and the second CSI.

[0168] In some optional embodiments, the first feedback information may also be determined based on whether the CSI feedback information includes the first CSI and / or the second CSI.

[0169] Exemplarily, when the CSI feedback information includes the first CSI, the first feedback information may indicate that the acquisition method of the CSI feedback information is the third method.

[0170] Also, for example, when the CSI feedback information includes the second CSI, the first feedback information may indicate that the method for acquiring the CSI feedback information is the first method.

[0171] Further, for example, when the CSI feedback information includes a first CSI and a second CSI, the first feedback information may indicate that the method of acquiring the CSI feedback information uses the first method and the third method.

[0172] In some optional embodiments, the information indicating the first consistency information between the channel-related information and the first information may be a quantized value of the first similarity information and / or a quantized value of the first error information. The embodiment of the present disclosure is not particularly limited in the method of obtaining the quantized value.

[0173] Illustratively, the first consistency information is the cosine similarity between the channel related information and the first information, and the information indicating the first consistency information between the channel related information and the first information is a quantized value of the cosine similarity. Specifically, after obtaining the cosine similarity between the channel related information and the first information as described above, the value of the information indicating the first consistency information between the channel related information and the first information can be determined using the correspondence relationship shown in the following table. [Table 1]

[0174] As shown in the above table, when the value of the cosine similarity is within the range [0, 0.375], the information indicating the first consistency information between the channel related information and the first information indicates a value of 0; when the value of the cosine similarity is within the range (0.375, 0.675], the information indicating the first consistency information between the channel related information and the first information indicates a value of 1; when the value of the cosine similarity is within the range (0.675, 0.875], the information indicating the first consistency information between the channel related information and the first information indicates a value of 2; and when the value of the cosine similarity is within the range (0.875, 1], the information indicating the first consistency information between the channel related information and the first information indicates a value of 3.

[0175] Note that the data in the above table is merely an example and does not constitute a specific limitation of the present disclosure.

[0176] In an optional embodiment, the first feedback information can also be directly determined based on the first consistency information. Specifically, the method includes the following steps:

[0177] (1) Determining that the first feedback information includes information indicating that the CSI feedback information is obtained using a first method when a first condition is satisfied, the first condition including at least that a value of the first consistency information falls within a first range.

[0178] (2) determining that the first feedback information includes information indicating that the CSI feedback information is obtained using a third method when a second condition is satisfied, the second condition including at least that a value of the first consistency information falls within a second range.

[0179] (3) determining that the first feedback information includes information indicating that the CSI feedback information is obtained using the first method and the third method when a third condition is satisfied, the third condition including at least that a value of the first consistency information falls within a third range.

[0180] In some optional embodiments, when the third method is a codebook technique (i.e., the first CSI is obtained by processing the channel-related information based on the codebook technique), the first CSI may include any one or more of information such as a precoding matrix indicator (PMI) and a rank indicator (RI).

[0181] In some optional embodiments, when transmitting the second CSI to the network device, the first feedback information may further include information indicating the accuracy of the CSI feedback information to indicate the accuracy of the second CSI, and the method of obtaining the accuracy is not particularly limited in the embodiments of the present disclosure. Exemplary methods include, but are not limited to, the following methods:

[0182] determining that the first feedback information includes information indicating that the CSI feedback information has a first accuracy if a first condition is satisfied; or determining, if a second condition is satisfied, that the first feedback information includes information indicating that the CSI feedback information has a second accuracy; Alternatively, if a third condition is satisfied, it is determined that the first feedback information includes information indicating that the CSI feedback information has a third precision.

[0183] Here, the first precision is greater than the second precision, and the second precision is greater than the third precision.

[0184] In some optional embodiments, when transmitting the second CSI to the network device, the first feedback information may also include information indicating whether the CSI feedback information is accurate or not.

[0185] Specifically, taking the above as an example, when the first condition and the second condition are met, it can be determined that the CSI feedback information is relatively accurate, and in this case, the first feedback information includes information indicating that the CSI feedback information is accurate; on the other hand, when the third condition is met, it can be determined that the CSI feedback information is inaccurate, and in this case, the first feedback information includes information indicating that the CSI feedback information is inaccurate.

[0186] Optionally, it may be determined that if the second condition is met, the CSI feedback information is considered to be inaccurate and the first feedback information includes information indicating that the CSI feedback information is inaccurate.

[0187] In some further optional embodiments, when transmitting the second CSI to the network device, the first feedback information may also include information indicating whether the CSI feedback information is valid or not.

[0188] Specifically, taking the above as an example, when the first condition and the second condition are met, it can be determined that the CSI feedback information is relatively accurate, and in this case, the first feedback information includes information indicating that the CSI feedback information is valid; on the other hand, when the third condition is met, it can be determined that the CSI feedback information is inaccurate, and in this case, the first feedback information includes information indicating that the CSI feedback information is invalid.

[0189] Optionally, it may be determined that if the second condition is met, the CSI feedback information is considered to be inaccurate and the first feedback information includes information indicating that the CSI feedback information is invalid.

[0190] In another optional embodiment, when transmitting the second CSI to the network device, the first feedback information may also include information indicating a quality level of the CSI feedback information.

[0191] Specifically, taking the above as an example, it may be determined that when a first condition is satisfied, the CSI feedback information is accurate, and in this case, the first feedback information includes information indicating that the quality level of the CSI feedback information is a first quality level; or may determine that the CSI feedback information is relatively accurate if a second condition is satisfied, in which case the first feedback information includes information indicating that a quality level of the CSI feedback information is a second quality level; Alternatively, if a third condition is met, it may be determined that the CSI feedback information is inaccurate, and in this case, the first feedback information includes information indicating that the quality level of the CSI feedback information is a third quality level.

[0192] In addition, the first condition, the second condition, and the third condition corresponding to determining the first feedback information are the same as the conditions corresponding to the embodiment of determining the CSI feedback information above, and for specific details, reference may be made to the above embodiment, and no further description will be given here.

[0193] In the second alternative evaluation method, FIG. 7 is a flowchart 2 of a CSI evaluation method provided by an embodiment of the present disclosure. Note that the execution subject of this embodiment may be a terminal in the above scene. As shown in FIG. 7, this CSI evaluation process may include the following steps:

[0194] S701, using a third method, processing channel-related information to obtain a first CSI.

[0195] In addition, the third method is any CSI processing method different from the first method. For example, the first method is an encoding technique, and the third method may be a codebook technique or a data-driven technique, etc.

[0196] Taking the third method as an example that it is a codebook technique, when processing the channel-related information based on the codebook technique to obtain the first CSI, the following methods are included but not limited to:

[0197] Calculate each precoding matrix of the channel-related information and the codebook, respectively, and set the precoding matrix and / or rank of the maximum (or minimum) calculation result as the first CSI; Alternatively, a first index is determined based on the channel-related information and each precoding matrix in the codebook, and the precoding matrix and / or rank corresponding to the maximum or minimum first index is taken as the first CSI.

[0198] Optionally, the first metric is, for example, a signal to interference-noise ratio (SINR), a capacity, or the like.

[0199] S702, determining first consistency information based on the channel-related information and the first information.

[0200] S703, determining second consistency information based on the channel-related information and the first CSI.

[0201] As shown in Fig. 6(b), the first CSI is obtained by processing the channel-related information using a third method. In the embodiment of the present disclosure, the second consistency information between the channel-related information and the first CSI can be obtained by evaluating the first CSI using the channel-related information.

[0202] It should be appreciated that the second consistency information may include second similarity information and / or second error information between the channel-related information and the first CSI.

[0203] Exemplarily, the second similarity may be a cosine similarity between the channel-related information and the first CSI, and the second error information may be a normalized mean squared error or a mean squared error between the channel-related information and the first CSI.

[0204] In addition, in this embodiment, the method for determining the first consistency information is similar to the method for determining the first consistency information in FIG. 5, and the specific method can be referred to the above embodiment, and no further description will be given here.

[0205] The second consistency information is the second similarity, and taking the second similarity as an example of cosine similarity, the value ρ2 of the second similarity information can be obtained according to the following formula (5).

[0207] S70 4 , determining CSI feedback information and / or first feedback information based on the first consistency information and the second consistency information.

[0208] Specifically, depending on the condition satisfied by the first consistency information and the second consistency information, the corresponding CSI feedback information and / or the first feedback information also differ.

[0209] In one aspect, the CSI feedback information may include, but is not limited to, any one or more of the following:

[0210] I. determining that the CSI feedback information includes a second CSI if a fourth condition is satisfied, the fourth condition including at least that the first consistency information and the second consistency information satisfy a first relative relationship.

[0211] II. Determining that the CSI feedback information includes a first CSI when a fifth condition is satisfied, the fifth condition including at least that the first consistency information and the second consistency information satisfy a second relative relationship.

[0212] III. Determining that the CSI feedback information includes a first CSI and a second CSI when a sixth condition is satisfied, where the sixth condition at least includes that the first consistency information and the second consistency information satisfy a third relative relationship.

[0213] Here, the relative relationship is used to indicate the magnitude of the values ​​of the first consistency information and the second consistency information. For example, when the first consistency information and the second consistency information are similarity information, the larger the value of the similarity information, the better the corresponding consistency of the similarity information. When the first consistency information and the second consistency information are error information, the smaller the value of the error information, the better the corresponding consistency information of the error information.

[0214] Illustratively, taking as an example that both the first consistency information and the second consistency information are consistency information, the first aspect describes that when the value ρ1 of the first similarity information is greater than the value ρ2 of the second similarity information (i.e., the first consistency information and the second consistency information satisfy the first relative relationship and currently satisfy the fourth condition), the performance of performing CSI feedback using the first method is better, and in this case, it is determined that the CSI feedback information includes the second CSI.

[0215] In the second aspect, it is described that when ρ1 is smaller than ρ2 (i.e., the first consistency information and the second consistency information satisfy the second relative relationship and currently satisfy the fifth condition), the performance of CSI feedback using the third method is better, and in this case, it is determined that the CSI feedback information includes the first CSI.

[0216] In a third aspect, it is described that when ρ1 is equal to ρ2 (i.e., the first consistency information and the second consistency information satisfy the third relative relationship and currently satisfy the sixth condition), the performance of performing CSI feedback using the third method is basically the same as the performance of performing CSI feedback using the first method, and in this case, it is determined that the CSI feedback information includes the first CSI and the second CSI.

[0217] In some optional embodiments, the currently satisfied condition may also be determined based on the difference between the first similarity ρ1 and the second similarity ρ2, specifically including, but not limited to, at least one of the following:

[0218] If ρ1 is greater than ρ2, or if a difference between ρ1 and ρ2 is within a fourth range, determine that a fourth condition is currently satisfied, i.e., determine that the CSI feedback information includes a second CSI; or if ρ1 is smaller than ρ2, and the difference between ρ1 and ρ2 is not within a fourth range but is within a fifth range, determine that a fifth condition is currently satisfied, i.e., determine that the CSI feedback information includes the first CSI, where the fifth range is a range other than the fourth range; Or, if ρ1 is smaller than ρ2, and if the difference between ρ1 and ρ2 is within a sixth range, determine that the sixth condition is currently met, i.e., determine that the CSI feedback information includes the second CSI and the first CSI, where the sixth range is a subset or the entire set of the fourth range.

[0219] Some alternative embodiments may also include the following methods.

[0220] If ρ1 is smaller than ρ2, and if the difference between ρ1 and ρ2 is within a seventh range, determine that the sixth condition is currently met, i.e., determine that the CSI feedback information includes the second CSI and the first CSI, where the seventh range is a subset or the entire set of the fourth range.

[0221] Or, if ρ1 is smaller than ρ2, the CSI feedback information does not include the second CSI if the difference between ρ1 and ρ2 is within an eighth range, where the eighth range is a subset or the full set of the fourth range.

[0222] As an optional embodiment, in one embodiment, the first feedback information may also be determined based on whether the CSI feedback information includes the first CSI and / or the second CSI.

[0223] Exemplarily, when the CSI feedback information includes the first CSI, the first feedback information may indicate that the method for obtaining the CSI feedback information is the third method.

[0224] Also, for example, when the CSI feedback information includes the second CSI, the first feedback information may indicate that the method for acquiring the CSI feedback information is the first method.

[0225] Further, for example, when the CSI feedback information includes a first CSI and a second CSI, the first feedback information may indicate that the method of acquiring the CSI feedback information is the first method and the third method.

[0226] In another optional embodiment, the first feedback information can also be directly determined according to the relative relationship between the first consistency information and the second consistency information. Specifically, the following cases are included but not limited to:

[0227] I. determining that the first feedback information includes information indicating that the CSI feedback information is obtained using a first method when a fourth condition is satisfied, where the fourth condition at least includes that the first consistency information and the second consistency information satisfy a first correlation; II. determining that the first feedback information includes information indicating that the CSI feedback information is obtained by using a third method when a fifth condition is satisfied, where the fifth condition at least includes that the first consistency information and the second consistency information satisfy a second correlation; III. determining that, when a sixth condition is satisfied, the first feedback information includes information indicating that the CSI feedback information is obtained using the first method and the third method, wherein the sixth condition at least includes that the first consistency information and the second consistency information satisfy a third relative relationship.

[0228] In some alternative embodiments, the second consistency information may be a quantized value of the second similarity information and / or a quantized value of the second error information, while the first feedback information is: Second Similarity Information The quantized value may be a quantized value of 1, and the method of obtaining the quantized value is not particularly limited in the embodiment of the present disclosure.

[0229] In addition, the fourth condition, the fifth condition, and the sixth condition corresponding to determining the first feedback information are the same as the conditions corresponding to the embodiment of determining the CSI feedback information above, and for specific details, reference may be made to the above embodiment, and no further description will be given here.

[0230] Optionally, the CSI feedback information may also be determined based on the first consistency information and / or the second consistency information, which may include, but is not limited to, any of the following:

[0231] If the seventh condition and / or the eighth condition is satisfied, the CSI feedback information is not transmitted.

[0232] Here, the seventh condition includes at least the value of the first consistency information falling within a fourth range, and the eighth condition includes at least the first consistency information and the second consistency information satisfying a fourth relative relationship.

[0233] Note that the seventh condition is similar to the second condition in the above embodiment, the eighth condition is similar to the fifth condition in the above embodiment, while the fourth range is similar to the second range in the above embodiment, and the fourth relative relationship is similar to the second relative relationship in the above embodiment.

[0234] That is, when the value ρ1 of the first consistency information is smaller than R2 (i.e., the second condition is satisfied), it is determined that the similarity between the channel-related information and the first information is low, and in this case, it is not necessary to transmit CSI feedback information; or when the value ρ1 of the first error information is smaller than the value ρ2 of the second error information (i.e., the first consistency information and the second consistency information satisfy the second relative relationship), it is explained that the performance of performing CSI feedback using the first method is poor, and in this case, it is also not necessary to transmit CSI feedback information.

[0235] In some embodiments, No. When transmitting the second CSI to the network device, the first feedback information may further include information indicating the accuracy of the CSI feedback information to indicate the accuracy of the second CSI, and the method of obtaining the accuracy is not particularly limited in the embodiments of the present disclosure. Exemplary methods include, but are not limited to, the following methods:

[0236] determining that the first feedback information includes information indicating that the CSI feedback information has a first accuracy if a fourth condition is satisfied; or determining, if a fifth condition is satisfied, that the first feedback information includes information indicating that the CSI feedback information has a second accuracy; Alternatively, if a sixth condition is satisfied, it determines that the first feedback information includes information indicating that the CSI feedback information has the third precision.

[0237] Here, the first precision is greater than the second precision, and the second precision is greater than the third precision.

[0238] In addition, the fourth, fifth and sixth conditions corresponding to determining the accuracy are the same as the conditions corresponding to the embodiment for determining the CSI feedback information described above. For details, refer to the above embodiment. No further description will be given here.

[0239] In some embodiments, the terminal transmits CSI feedback information and / or first feedback information to the network device, and the embodiments of the present disclosure are not particularly limited. For example, in embodiment 1, the terminal can first transmit the first feedback information to the network device, and the network device can accordingly determine whether to receive the CSI feedback information based on the first feedback information, in which case, the first feedback information is: information indicating how to obtain CSI feedback information; Or, information indicating the accuracy of the CSI feedback information, or information indicative of first consistency information between the channel-related information and the first information; or information indicative of second consistency information between the channel-related information and the first CSI; Or, information indicating whether CSI feedback information has been transmitted; Includes at least one of the following.

[0240] Next, the above-mentioned embodiment 1 will be exemplarily described with reference to FIG.

[0251] Here, the first precision is greater than the second precision, and the second precision is greater than the third precision.

[0252] S806, when determining to receive CSI feedback information, the network device receives the CSI feedback information, and determines a CSI based on the CSI feedback information and / or the first feedback information.

[0253] Note that the first feedback information and the CSI feedback information may be transmitted independently or simultaneously.

[0254] When the first feedback information and the CSI feedback information are transmitted independently, for example, a feedback method can be used in which the first feedback information is set to a long period and the CSI feedback information is set to a short period, and all feedback operations within the long period correspond to the first feedback information.

[0255] Specifically, the above step S806 includes at least one of the following:

[0256] (1) The first feedback information is CSI feedback information How to get To show Information if the first feedback information includes the first feedback information, an acquisition method for the CSI feedback information can be determined based on the acquisition method indicated by the first feedback information, and the CSI is acquired using a method corresponding to the acquisition method.

[0257] For example, the first feedback information includes CSI feedback information How to get To show Information is a first method, analyze the CSI feedback information to obtain a second CSI, and process the second CSI using a second method corresponding to the first method to obtain CSI.

[0258] Taking the first method as an example that it is an encoding technique, the network device analyzes the CSI feedback information to obtain a second CSI, and then processes the second CSI based on a decoder module to obtain the CSI, where the second CSI is obtained by the terminal processing the channel-related information based on an encoder module, and the encoder module and the decoder module are obtained by performing joint training.

[0259] In some optional embodiments, in addition to the decoder module, the network device may use any one or more modules, such as an inverse quantizer module, a channel reconstruction module, etc., in obtaining the CSI, and the embodiments of the present disclosure are not particularly limited.

[0260] Similarly, the first feedback information includes CSI feedback information How to get To show Information If the third method is included, the CSI feedback information is analyzed to obtain the CSI.

[0266] Illustratively, the first feedback information includes first consistency information, and when the value of the first consistency information satisfies a first condition, it is described that the performance of performing CSI feedback using the first method is good. In this case, it is determined that the method for obtaining CSI feedback information is the first method. For cases where other conditions are satisfied, refer to the embodiment shown in FIG. 5 above, and they will not be described one by one here.

[0267] Accordingly, it is described that the first feedback information includes first consistency information and second consistency information, and when the value of the first consistency information and the value of the second consistency information satisfy the fourth condition, the performance of performing CSI feedback using the first method is good, and in this case, it is determined that the method for obtaining CSI feedback information is the first method. For cases where other conditions are satisfied, please refer to the embodiment shown in Figure 7 above, and they will not be described one by one here.

[0268] In some optional embodiments, when CSI feedback information is received, and the first feedback information includes a first consistency information value and / or a second consistency information value, the CSI may be directly determined by the CSI feedback information based on the first consistency information value and / or the second consistency information value.

[0269] For example, the first feedback information includes first consistency information, and when the value of the first consistency information satisfies a first condition, the performance of CSI feedback using the first method is good, and in this case, the CSI feedback information is directly analyzed to obtain the CSI. For cases where other conditions are satisfied, please refer to the embodiment shown in FIG. 5 above, and will not be described here one by one.

[0270] In some optional embodiments, when the first feedback information includes a quantized value of the first consistency information and / or a quantized value of the second consistency information, the CSI feedback information may be determined based on the quantized value.

[0271] Illustratively, taking the first consistency information as an example of cosine similarity, it is described that when the quantized value of the first consistency information is 0, the similarity between the channel-related information and the first information is low, that is, the accuracy of the CSI obtained using the first method is low. In this case, the method for obtaining CSI feedback information can be determined to be the third method. For the case where the quantized value of the first consistency information is another value, please refer to the embodiment shown in Figure 5 above, and it will not be described here one by one.

[0278] In one alternative embodiment, the first feedback information may include a second feedback signal for indicating the accuracy or quality level of the second CSI in the CSI feedback information. Information If the CSI feedback information currently being fed back is included, a method for acquiring the CSI feedback information may be determined based on the accuracy or quality level, and the CSI may be acquired based on a method corresponding to the acquisition method.

[0279] Specifically, when the accuracy of the CSI feedback information is a first accuracy or the quality is a first quality level, a current CSI feedback information acquisition method is determined to be a first method, and a second method corresponding to the first method is used to acquire the CSI; or, when the accuracy of the CSI feedback information is a second accuracy or the quality is a second quality level, determine that a current method for acquiring the CSI feedback information is the first method and the third method, and acquire the CSI using the second method corresponding to the first method, or acquire the CSI using the third method; Or, if the accuracy of the CSI feedback information is a third accuracy, or if the quality is a third quality level, determine that the current method for acquiring CSI feedback information is a third method, and acquire CSI using the third method.

[0280] In an embodiment of the present disclosure, the network device first determines whether to receive CSI feedback information based on the first feedback information, so that when the accuracy of the CSI feedback information is low, there is no need to receive and process the CSI feedback information, and the power consumption of the network device can be reduced.

[0281] In the second embodiment, when it is determined that CSI feedback information needs to be sent to the network device, the first feedback information can be included in the CSI feedback information, thereby simultaneously sending the CSI feedback information and the first feedback information to the network device, i.e., the CSI feedback information and the first feedback information. In this case, the first feedback information is: information indicating how to obtain CSI feedback information; Or, information indicating the accuracy of the CSI feedback information, or information indicative of first consistency information between the channel-related information and the first information; or information indicative of second consistency information between the channel-related information and the first CSI; Includes at least one of the following.
