The term "and / or" in this document is only used to describe the association relationship between the associated objects. For example, A and / or B can represent three cases: A alone, A and B together, and B alone.

[0051] For the convenience of understanding the technical solutions of the embodiments of the present application, the related technologies of the embodiments of the present application are described as follows. The related technologies below can be combined with the technical solutions of the embodiments of the present application in any manner, and all of them belong to the protection scope of the embodiments of the present application.

[0052] In a wireless communication system (such as a 3G, 4G / LTE, 5G / NR, 6G, WiFi system, etc.), RS (which can also be called a pilot) is widely used, including:

[0053] Demodulation Reference Signal (DMRS): In order to reduce the demodulation complexity of the receiving end, and also to improve the receiving performance, a demodulation reference signal (such as DMRS) is sent together with data. For example, DMRS used by a physical uplink shared channel (PUSCH), DMRS used by a physical uplink control channel (PUCCH), DMRS used by a physical downlink shared channel (PDSCH), and DMRS used by a physical downlink control channel (PDCCH). For another example, in a sidelink (SL), there is also a corresponding demodulation reference signal.

[0054] Measurement Reference Signal: In order to measure channel characteristics and / or interference, many different types of measurement reference signals are also introduced, such as channel state information reference signals (CSI-RS for downlink), sounding reference signals (SRS for uplink), etc.; measurement reference signals can also be used for beam measurement (such as CSI-RS in 5G, synchronization signal / PBCH block (SS / PBCH)), mobility measurement (such as CSI-RS in 5G, SS / PBCH), etc.

[0055] Other RS: For example, in 5G, in order to help the receiving end to obtain more accurate time-frequency synchronization information, and / or channel statistical characteristics (for example, in order to assist the receiving end to improve channel estimation and / or reception performance), the tracking reference signal (Tracking RS or CSI-RS for Tracking, TRS) is introduced; in order to eliminate the phase error of the high frequency band, the phase tracking reference signal (Phase-tracking Reference Signals, PT-RS) is introduced.

[0056] The signals introduced above generally have corresponding signals for uplink, downlink and sidelink. Different links may vary (for example, the pattern and / or sequence may be different), but the functions are similar.

[0057] As introduced before, the introduction of various reference signals can well help the receiving end to reduce complexity and improve reception performance. However, the parameters of various RSs also occupy time-frequency resources, thereby reducing the time-frequency resources actually used for data transmission. How to reduce the overhead (i.e. occupied time-frequency resources) of RS is a problem that must be considered in communication systems, and is also an important goal of system optimization.

[0058] Traditional communication algorithms have been widely applied, and in related technologies, various RS designs and configurations are optimized for these traditional communication algorithms. With the development of technology, various new and more advanced communication algorithms / methods (for the sake of simplicity, we will refer to them as algorithms or methods in the following) are gradually developed (for example, statistical-based methods, machine learning-based methods, artificial intelligence (AI) -based methods, deep learning (DL) -based methods, etc.), which can be more applied in communication systems in the future to improve system performance.

[0059] These new algorithms / methods have more powerful capabilities and can reduce the overhead of RS. Therefore, based on the potential capabilities of these new algorithms / methods, how to reduce the RS overhead will be an important research point in future wireless communication design.

[0060] In the NR system, the reference signal design is relatively flexible, and appropriate RS can be indicated by network configuration or signaling to achieve a compromise between reception performance and RS overhead. However, the existing scheme still has certain limitations:

[0061] The current RS scheme is based on traditional communication algorithms and fails to fully utilize the capabilities of more advanced algorithms / methods. Utilizing more advanced communication algorithms / methods can further reduce the RS overhead.

[0062] Some new dimensions have not been utilized. Utilizing these new dimensions can further reduce RS overhead while ensuring reception performance.

[0063] To fully explore and utilize the capabilities of new algorithms / methods, it is often necessary to collect certain data for algorithm development and optimization. Based on the collected data, algorithm development or AI model training can be carried out.

[0064] Traditional communication algorithms generally exhibit good adaptability across various scenarios. However, data-driven algorithms or AI models often overfit data, resulting in limitations in their generalization ability—that is, whether they can achieve good performance in all scenarios. Therefore, once a new algorithm is developed or an AI model is trained, its performance needs to be monitored during network applications to ensure communication reliability. This application provides a specific solution design for this situation (monitoring the performance of algorithm applications or AI models). It should be noted that in the following description, we use the performance monitoring of AI model inference as an example to describe the solution. However, the AI ​​model inference in these solutions can also be replaced by using algorithms to obtain output, or using receivers to obtain output, etc. This application does not limit the specific application method of the monitoring information.

[0065] It should be understood that the technical solutions of the embodiments of this application can be applied to centimeter wave communication scenarios, millimeter wave communication scenarios, low frequency communication scenarios, and various other communication scenarios.

[0066] Figure 2 is a schematic flowchart of an information transmission method according to an embodiment of this application. This method can optionally be applied to the system shown in Figure 1, but is not limited thereto. The method includes:

[0067] S210, the first device sends a first reporting signaling message; wherein, the first reporting signaling message includes first information obtained based on the first RS resource.

[0068] Optionally, the device type of the first device can be a terminal device. The first device can send the first reporting signaling to a second device, and the device type of the second device can be a network device or a terminal device. That is, the embodiments of the present application can be applied to terminal device and network communication, and can also be applied to terminal device and terminal device communication (such as SL transmission, D2D transmission, etc.). For example, the first device includes a first terminal device, and the second device includes a first network device; or the first device includes a first terminal device, and the second device includes a second terminal device. For the convenience of description and concise description, in some examples of the present application, the introduction of the technical solutions will be taken as an example of terminal device and network communication. It can be understood that the introduced technical solutions can also be used for terminal device and terminal device communication. The popularization of this application scenario can be thought of by those skilled in the art, and should be covered within the protection scope of the present application.

[0069] In actual application, the RS is transmitted on its corresponding RS resource, so a certain RS can be represented by its corresponding RS resource. It can be understood that in the embodiments of the present application, the configuration / indication / application of the RS resource can also be understood as the configuration / indication / application of the RS.

[0070] In the embodiments of the present application, the first information is obtained based on the first RS resource, or in other words, obtained based on the RS on the first RS resource. For example, the first information can be a channel measurement result obtained based on the first RS resource or other information related to the channel measurement result, such as information predicted or inferred based on the channel measurement result, error information, triggered event information, etc.

[0071] Optionally, the first information can be obtained based on a first model. Exemplarily, the first model can be an algorithm model or an AI model related to the RS. In this case, the first information can be used to monitor the first model. For example, the first device obtains the first CSI based on the first RS resource, uses the first model to predict / infer based on the first CSI to obtain the second CSI, and the first information can include the second CSI or other information related to the second CSI, such as information for evaluating the accuracy of the second CSI, based on which the first model can be monitored whether it can accurately obtain the second CSI.

[0072] In the embodiments of the present application, the first device sends the first reporting signaling to report the first information obtained based on the first RS resource, so that the first information can be used to monitor the performance of the RS configuration or the RS related algorithm / model, which helps to reduce the overhead of the RS.

[0073] Corresponding to the above method, FIG. 3 is a schematic flowchart of a resource configuration method performed by a second device according to an embodiment of the present application, which includes:

[0074] S310, the second device receives the first reporting signaling; wherein the first reporting signaling comprises the first information obtained by the first device based on the first RS resource.

[0075] In the embodiments of the present application, the first device sends the first reporting signaling to report the first information obtained based on the first RS resource, and the second device receives the first reporting signaling. In this way, the second device can monitor the performance of the RS configuration or the RS related algorithm / model by using the first information, which helps to reduce the RS overhead.

[0076] In order to better monitor the RS related algorithm / model, in some embodiments, the first device reports information related to the first RS resource and the second RS resource, for example, the first information is obtained based on the first RS resource and the second RS resource, or the first device further reports information obtained based on the second RS resource through other reporting signaling.

[0077] In some embodiments, the information transmission method further comprises: the second device sends first indication information. Correspondingly, the first device receives the first indication information. Wherein, the first indication information is used for the first device to determine the first RS resource. Specifically, the first indication information indicates the first RS resource, and the first device determines the first RS resource based on the first indication information.

[0078] Optionally, the first device receives the fifth indication information sent by the second device, and the first device determines the first RS resource group according to the fifth indication information, and the first RS resource belongs to one RS resource in the first RS resource group. By indicating one RS resource group, the first device can measure and / or report according to multiple RS resources, and the signaling flexibility is better.

[0079] In some embodiments, the information transmission method further comprises: the second device sends third indication information. Correspondingly, the first device receives the third indication information. Wherein, the third indication information is used for the first device to determine the second RS resource.

[0080] Optionally, the first device receives the tenth indication information sent by the second device, and the first device determines the second RS resource group according to the tenth indication information, and the second RS resource belongs to one RS resource in the second RS resource group. By indicating one RS resource group, the first device can measure and / or report according to multiple RS resources, and the signaling flexibility is better.

[0081] It should be noted that the RS resource group can also be referred to as RS set (RS group) or RS resource set.

[0082] It should be noted that the concept of RS resource group may or may not appear in the actual protocol. The resource group (for example, the first RS resource group and the second RS resource group) in the embodiments of the present application can be the resource group actually appearing in the protocol, or can be a concept of logically dividing different RS resources, or can be a description method introduced for the convenience of description, and does not actually appear in the protocol (for example, there are two RS resources, and the specific configuration / purpose is different, and then the first RS resource can be classified into one RS group, and the second RS resource can be classified into another RS group).

[0083] In some embodiments, the first RS resource and the second RS resource are RS resources of the same type.

[0084] As an example, the first RS resource is a CSI-RS resource, and the second RS resource is a CSI-RS resource. As an example, the RS resources included in the first RS resource group are CSI-RS resources, and the RS resources included in the second RS resource group are CSI-RS resources.

[0085] As an example, the first RS resource is a DMRS, and the second RS resource is a DMRS. As an example, the RS resources included in the first RS resource group are DMRSs, and the RS resources included in the second RS resource group are DMRSs. The DMRS can help demodulate data and / or control signaling, but its essence is also to obtain channel information (which can also be called equivalent channel), so the DMRS can also be understood as being used for channel measurement. Optionally, the above-mentioned DMRS can be a DMRS of a data channel (for example, a DMRS of a PDSCH), or the above-mentioned DMRS can be a DMRS of a control channel (for example, a DMRS of a PDCCH).

[0086] As other examples, the first RS resource and the second RS resource can also be RS resources of other types (i.e., non-CSI-RS resources or non-DMRS resources). As other examples, the RS resources included in the first RS resource group and the second RS resource group can be RS resources of other types (i.e., non-CSI-RS resources, non-DMRS).

[0087] Optionally, the first indication information can be transmitted through radio resource control (RRC) signaling, or through media access control element (MAC Control Element, MAC CE) signaling, or through system information transmission, or through broadcast information transmission, or through downlink control information (Downlink Control Information, DCI) transmission.

[0088] Optionally, the third indication information can be transmitted by RRC signaling, or by MAC CE signaling, or by system information transmission, or by broadcast information transmission, or by DCI transmission.

[0089] Optionally, the fifth indication information can be transmitted by RRC signaling, or by MAC CE signaling, or by system information transmission, or by broadcast information transmission, or by DCI transmission.

[0090] Optionally, the tenth indication information can be transmitted by RRC signaling, or by MAC CE signaling, or by system information transmission, or by broadcast information transmission, or by DCI transmission.

[0091] There can be different options for the relationship between the fifth indication information and the first indication information.

[0092] One embodiment is that the fifth indication information and the first indication information are the same information; in this way, the signaling overhead can be compressed.

[0093] One embodiment is that the fifth indication information is contained in the first indication information; in this way, the signaling overhead can be compressed.

[0094] Another embodiment is that the fifth indication information and the first indication information are transmitted in the same signaling; in this way, the signaling overhead is smaller than when they are transmitted by different signaling, and the flexibility is higher than when they are the same information or have a containing relationship.

[0095] Another embodiment is that the fifth indication information and the first indication information are transmitted by different signaling. In this way, the signaling design flexibility is better.

[0096] There can be different options for the relationship between the tenth indication information and the third indication information.

[0097] One embodiment is that the tenth indication information and the third indication information are the same information; in this way, the signaling overhead can be compressed.

[0098] One embodiment is that the tenth indication information is contained in the third indication information; in this way, the signaling overhead can be compressed.

[0099] Another embodiment is that the tenth indication information and the third indication information are transmitted in the same signaling; in this way, the signaling overhead is smaller than when they are transmitted by different signaling, and the flexibility is higher than when they are the same information or have a containing relationship.

[0100] Another embodiment is that the tenth indication information and the third indication information are transmitted by different signaling. In this way, the signaling design flexibility is better.

[0101] There can be different options for the relationship between the first indication information and the third indication information.

[0102] In one embodiment, the first indication information and the third indication information are the same information; in this way, the signaling overhead can be compressed.

[0103] In one embodiment, the first indication information is contained in the third indication information; in this way, the signaling overhead can be compressed.

[0104] In another embodiment, the first indication information and the third indication information are transmitted in the same signaling; in this way, the signaling overhead is smaller than that of transmitting the two through different signaling, and the flexibility is higher than that of the two being the same information or having a containing relationship.

[0105] In another embodiment, the first indication information and the third indication information are transmitted through different signaling. In this way, the signaling design flexibility is better.

[0106] In some embodiments, the first RS resource is used for channel measurement, and the first information is obtained based on the channel measurement of the first RS resource.

[0107] Exemplarily, the channel measurement of the first RS resource is used to obtain channel state information (CSI), or is used to demodulate data and / or control information.

[0108] Optionally, the CSI includes one or more of the following information: channel matrix information, channel eigen vector information, precoding matrix indicator (PMI) information, channel quality indicator (CQI) information, rank indicator (RI) information.

[0109] For example, the first device can obtain, based on the measurement of the first RS resource, a channel (or referred to as a channel matrix), and / or an eigen vector corresponding to the channel, and / or a processing of the channel (for example, information of the channel in the angle-delay domain), and / or a PMI corresponding to the channel, and / or an RI.

[0110] For another example, the first device can demodulate data and / or control information based on the RS measurement on the first RS resource (for example, demodulate PDSCH based on the first RS resource, and for another example, demodulate PDCCH based on the first RS resource).

[0111] Optionally, the second device can indicate, by signaling (denoted as eleventh indication information), a measurement quantity or a reporting quantity for the first device. That is, the eleventh indication information indicates a specific measurement quantity (measurement metric, or measurement quantity) or a specific reporting quantity (report / reporting metric, or report / reporting quantity). In this way, network optimization can be more flexible. Illustratively, when the first RS resource is used to obtain CSI, the second device indicates, by the eleventh indication information, a measurement quantity or a reporting quantity reported by the first device to the second device when performing CSI feedback.

[0112] For transmission of the eleventh indication information:

[0113] In one embodiment, the eleventh indication information and the first indication information are the same information; in this way, signaling overhead can be compressed.

[0114] In one embodiment, the eleventh indication information is contained in the first indication information; in this way, signaling overhead can be compressed.

[0115] In another embodiment, the eleventh indication information and the first indication information are transmitted in the same signaling; in this way, signaling overhead is smaller than when the two are transmitted by different signaling, and flexibility is higher than when the two are the same information or have a containing relationship.

[0116] In another embodiment, the eleventh indication information and the first indication information are transmitted by different signaling; in this way, signaling design flexibility is better.

[0117] In some embodiments, the number of resources of the first RS resource is less than the number of resources of the second RS resource. In this way, the first device performs channel measurement based on the first RS resource and the second RS resource respectively, and the application effect of the first RS resource can be reflected by comparison between the results corresponding to the first RS resource and the second RS resource respectively, so as to monitor and optimize the algorithm / model related to the first RS resource, which is conducive to using a smaller number of RS resources and reducing RS overhead.

[0118] In some embodiments, the number of resources of the first RS resource in a first dimension is less than the number of resources of the second RS resource in the first dimension, and the first dimension includes one or more of a port, a space domain, a time domain, and a frequency domain.

[0119] For example, the first dimension includes ports, or the first dimension includes a spatial domain, and the resources on the spatial domain include ports, then the number of ports of the first RS resource is less than the number of ports of the second RS resource. For another example, the first dimension includes a time domain, then the number of resources of the first RS resource in the time domain is less than the number of resources of the second RS resource in the time domain. For another example, the first dimension includes a frequency domain, then the number of resources of the first RS resource in the frequency domain is less than the number of resources of the second RS resource in the frequency domain.

[0120] It should be noted that, in the embodiments of the present application, the number of resources of the first RS resource is less than the number of resources of the second RS resource, which can include that the number of resources of the first RS resource is less than the number of resources of the second RS resource in the same range. For example, the number of frequency domain resources of the first RS resource is less than the number of frequency domain resources of the second RS resource in the same frequency domain range (such as one or more RBs), that is, the frequency domain density of the first RS resource is less than the frequency domain density of the second RS resource. For another example, the number of time domain resources of the first RS resource is less than the number of time domain resources of the second RS resource in the same time domain range (such as one time slot or one subframe), that is, the time domain density of the first RS resource is less than the time domain density of the second RS resource.

[0121] There can be different implementation methods for the first RS resource and the second RS resource, and some examples are given below.

[0122] Example 1: The number of ports (K1) of the first RS resource is less than the number of ports (K2) of the second RS resource.

[0123] For example, the first RS resource has K1 ports, and the second RS resource has K2=N*K1 ports, where N is a positive integer, for example, N can be 2 or 4 or 8, or other values (such as 3, or 6, etc.). It should be noted that K2 can also not be a positive integer multiple of K1, but a positive integer greater than K1. In this way, fewer ports can be used to measure the channel, thereby reducing the RS overhead, increasing the available resources for transmission, and improving system performance.

[0124] A typical application scenario is a deployment scenario with a large number of base station antennas (for example, a wireless communication system in the centimeter wave frequency band). If the network needs the UE to measure all the ports (for example, based on the second RS resource for measurement), and then the UE feeds back the precoding matrix indication PMI according to the measurement result, and possibly feeds back the Rank and / or QCI information, etc. Because the number of base station antennas is large, K2 will be large, which will result in a large overhead of downlink measurement signals. One way is to measure a smaller number of RS resources (for example, based on the first RS resource for measurement), and then predict the PMI, and / or Rank, and / or CQI corresponding to the K2 ports. Here, prediction can also be referred to as estimation or derivation or inference or learning. If each port of the first RS resource and the second RS resource occupies the same time-frequency resource (the number of ports is different), this method can reduce the downlink measurement overhead by 1-K1 / K2. If K1 = 8 and K2 = 64, the downlink measurement RS overhead can be reduced by 7 / 8 (87.5%). If K1 = 16 and K2 = 64, the downlink measurement RS overhead can be reduced by 3 / 4 (75%).

[0125] In order to complete the above prediction work, some corresponding data is often needed to extract statistical characteristics, or to train / monitor / optimize the AI model, or to train / monitor / optimize the machine learning algorithm. It can be understood that in actual application, a variety of schemes can be adopted to support the above prediction work, and the specific scheme adopted by the embodiments of the present application is not limited. The important thing is that no matter what scheme is adopted, a data pair needs to be obtained: information based on K1 ports (for example, channel information or PMI or other information obtained based on the first RS resource measurement), denoted as data A, and information based on K2 ports (for example, channel information or PMI or other information obtained based on the second RS resource measurement), denoted as data B. Such a pair of data can be referred to as a sample (data A, data B). In actual application, a plurality of such samples often need to be collected. If the network indicates that the first RS resource and the second RS resource have a correlation relationship, the UE knows that the sample (i.e., the data pair) can be obtained according to the two information and the relationship, and these collected data (i.e., a plurality of samples) can be used for the development and research of the prediction scheme. Alternatively, the network can indicate the first RS resource and the second RS resource to the UE respectively, and the UE obtains the above-mentioned sample (i.e., the data pair) based on the network indication and reports it to the network, so that the network can collect data (i.e., a plurality of samples) for the development and research of the prediction scheme.

[0126] In an actual system, the correspondence between the ports of the first RS resource and the ports of the second RS resource can have different options:

[0127] Option 1: The correspondence between the ports of the first RS resource and the ports of the second RS resource is agreed according to a rule. For example, the port i (assuming the port number starts from 0, i.e., the port of the first RS resource can be 0, 1, 2, …, K1-1) of the first RS resource corresponds to the port k*i of the second RS resource, where k is a positive integer greater than 1. This option can reduce the signaling overhead.

[0128] Option 2: The correspondence between the ports of the first RS resource and the ports of the second RS resource is determined according to the signaling sent by the second device. This option indicates better flexibility.

[0129] Example 2: The frequency domain density of the first RS resource is less than the frequency domain density of the second RS resource. By measuring the complete channel through the RS with lower frequency domain density, the RS overhead can be reduced, the transmission resources can be increased, and the system performance can be improved.

[0130] For example, the first RS resource can have FD-Density1 resource elements (REs) in one RB, and the second RS resource can have FD-Density2 = N*FD-Density1 REs in one RB, where N is a positive integer, for example, N can be 2 or 4, or other values (such as 3, etc.). It should be noted that FD-Density2 can also not be a positive integer multiple of FD-Density1, but only a positive integer greater than FD-Density1.

[0131] For another example, the first RS resource is allocated with resources (such as 1 or more RE resources) on one RB in every FD1 RBs, and the second RS resource is allocated with resources (such as 1 or more RE resources) on one RB in every FD2 = FD1 / N RBs, where N is a positive integer, for example, N can be 2 or 4, or other values (such as 3, etc.). It should be noted that FD1 can also not be a positive integer multiple of FD2, as long as FD2<FD1, where both FD2 and FD1 are positive integers. In this case, the RS can only measure on part of the subband.

[0132] A typical application scenario is a wireless communication system with wide bandwidth (e.g., 4G, 5G, 6G, UWB, and WIFI evolution system, etc.). For example, in order to let the UE measure the downlink channel, the network can send a downlink measurement signal (e.g., CSI-RS) on all RBs, assuming that each port of the downlink measurement signal is allocated one RE on each PRB (FD2 = 1). The UE feeds back the precoding matrix indication PMI, and possibly feeds back the Rank and / or QCI information, etc. according to the measurement results. The dense downlink measurement RS can help the terminal obtain more accurate channel information. In an actual system, a large number of similar downlink measurement signals need to be sent, so the downlink measurement RS overhead is large. One way is to measure a RS resource with a smaller frequency domain density (e.g., based on the first RS resource for measurement), and then predict (or estimate, or speculate) a more accurate PMI, and / or Rank, and / or CQI. Assuming that each port of the first RS resource is allocated one RE in one RB in each FD1 PRB. If the number of ports of the first RS resource and the second RS resource is the same, and each port occupies the same time domain resource, then this method can reduce the downlink measurement overhead by 1-FD2 / FD1. If FD1 = 4 and FD2 = 1, the downlink measurement RS overhead can be reduced by 3 / 4 (75%).

[0133] In order to complete the above prediction work, some corresponding data is often needed to extract statistical characteristics, or to train / monitor / optimize AI models, or to train / monitor / optimize machine learning algorithms. It can be understood that in actual application, a variety of schemes can be adopted to support the above prediction work, and the specific scheme adopted by the embodiments of the present application is not limited. The important thing is that no matter what scheme is adopted, the data pair needs to be obtained: the information obtained based on the low frequency domain density downlink measurement RS (e.g., based on the first RS resource measurement, the channel information or PMI or other information is obtained), denoted as data A, and the information obtained based on the high frequency domain density downlink measurement RS (e.g., based on the second RS resource measurement, the channel information or PMI or other information is obtained), denoted as data B. Such a pair of data can be referred to as a sample (data A, data B). In actual application, a plurality of such samples often need to be collected. Therefore, the network indicates that the first RS resource and the second RS resource have a correlation relationship, so that the UE knows that the above-mentioned sample (i.e., the data pair) is obtained according to the two information and the relationship. These collected data (i.e., a plurality of samples) can be used for the development and research of the prediction scheme. Or, the network can indicate the first RS resource and the second RS resource to the UE respectively, and the UE obtains the above-mentioned sample (i.e., the data pair) based on the network indication and reports it to the network. Then the network can collect the data (i.e., a plurality of samples) for the development and research of the prediction scheme.

[0134] Example 3: The time-domain density of the first RS resource is less than the time-domain density of the second RS resource. By measuring the full channel with the RS with lower time-domain density, the RS overhead can be reduced, the resources available for transmission can be increased, and the system performance can be improved.

[0135] For example, the first RS resource can be allocated with resources on TD-Density1 symbols in a slot or a subframe, and the second RS resource can be allocated with resources on TD-Density2 = N * TD-Density1 symbols in a slot or a subframe, where N is a positive integer, for example, N can be 2 or 4 or 8, or other values (such as 3, etc.). It should be noted that TD-Density2 can also not be a positive integer multiple of TD-Density1, but only a positive integer greater than TD-Density1.

[0136] For another example, the first RS resource can be transmitted every TD1 symbols in a slot or a subframe, and the second RS resource can be transmitted every TD2 = TD1 / N symbols in a slot or a subframe, where N is a positive integer, for example, N can be 2 or 4, or other values (such as 3, etc.). It should be noted that TD1 can also not be a positive integer multiple of TD2, as long as TD2 < TD1, where TD2 and TD1 are both positive integers.

[0137] A typical application scenario is various wireless communication systems (such as 4G, 5G, 6G, UWB, and WIFI evolution systems, etc.), especially wireless communication in medium and high speed scenarios. For example, in order to ensure that the UE can obtain relatively accurate channel information in medium and high speed scenarios, the network often needs to configure downlink measurement signals with high density in time domain, such as transmitting downlink measurement signals on TD-Density1 = 2 or 4 symbols in a slot. For example, the UE feeds back the precoding matrix indication PMI according to the measurement result, and may also feed back the Rank and / or QCI information, etc. For another example, the UE demodulates data and / or control signaling according to the downlink measurement signal to which it belongs.

[0138] In a practical system, the network needs to send downlink measurement signals frequently, so the overhead of downlink measurement RS is large. One way is to measure a time-domain density smaller RS resource (for example, based on the first RS resource for measurement), and then predict (or estimate, speculate) more accurate PMI, and / or Rank, and / or CQI, or predict the channel to demodulate data and / or signaling. This method can reduce the downlink measurement overhead 1-TD-Density1 / TD-Density2. If TD-Density1=1, TD-Density2=4, then the downlink measurement RS overhead can be reduced by 3 / 4 (75%).

[0139] In order to complete the above prediction work, some corresponding data is often needed to extract statistical characteristics, or to train AI models, or to train machine learning algorithms. It can be understood that in practical applications, various schemes can be used to support the above prediction work, and the specific scheme adopted by the embodiments of the present application is not limited. The important thing is that no matter what scheme is adopted, the data pair needs to be obtained: the information obtained based on the low time-domain density downlink measurement RS (for example, based on the first RS resource measurement, the channel information or PMI or other information is obtained), denoted as data A, and the information obtained based on the high time-domain density downlink measurement RS (for example, based on the second RS resource measurement, the channel information or PMI or other information is obtained), denoted as data B. We call such a pair of data (data A, data B) a sample. In practical applications, it is often necessary to collect multiple such samples. If the network indicates that the first RS resource and the second RS resource have a correlation relationship, the UE knows that based on the information of the two and the relationship, the above-mentioned sample (i.e. data pair) can be obtained. These collected data (i.e. multiple samples) can be used for the development and research of prediction schemes. Or, the network can respectively indicate the first RS resource and the second RS resource to the UE, and the UE obtains the above-mentioned sample (i.e. data pair) based on the network indication and reports it to the network. Then the network can collect data (i.e. multiple samples) for the development and research of prediction schemes.

[0140] The above is introduced with 3 examples, and the combination scheme of the 3 examples also belongs to the protection scope of the present application, for example:

[0141] The port number (K1) of the first RS resource is less than the port number (K2) of the second RS resource, and the frequency domain density of the first RS resource is less than the frequency domain density of the second RS resource (combination scheme of example 1 and example 2);

[0142] The port quantity (K1) of the first RS resource is less than the port quantity (K2) of the second RS resource, and the time domain density of the first RS resource is less than the time domain density of the second RS resource (combination scheme of example 1 and example 3);

[0143] The time domain density of the first RS resource is less than the time domain density of the second RS resource, and the frequency domain density of the first RS resource is less than the frequency domain density of the second RS resource (combination scheme of example 2 and example 3);

[0144] The port quantity (K1) of the first RS resource is less than the port quantity (K2) of the second RS resource, and the frequency domain density of the first RS resource is less than the frequency domain density of the second RS resource, and the time domain density of the first RS resource is less than the time domain density of the second RS resource (combination scheme of example 1, example 2 and example 3).

[0145] The specific details of the above combination schemes will not be repeated here.

[0146] In some embodiments, the first device can determine that the first RS resource and the second RS resource have an association relationship, so as to facilitate the first device to report the results of the first RS resource and the second RS resource in association. The following will be exemplarily described for the indication of the association relationship between the first RS resource and the second RS resource.

[0147] The indication of the association relationship can have different implementation manners, including at least one of the following:

[0148] Manner 1: A first field in the configuration information of the first RS resource and a second field in the configuration information of the second RS resource have the same value.

[0149] Here, the first field and the second field can be the same field in the configuration information of the first RS resource and the configuration information of the second RS resource, in other words, the first field and the second field are fields with the same meaning or the same function, or in other words, the first field and the second field are used to indicate the same type of information, and the first field and the second field are only distinguished for different configuration information corresponding to different RS resources.

[0150] Optionally, the first indication information can indicate the configuration information of the first RS resource, or the first indication information can contain the configuration information of the first RS resource.

[0151] Optionally, the third indication information can indicate the configuration information of the second RS resource, or the third indication information can contain the configuration information of the second RS resource.

[0152] Compared with indicating the association relationship between the RS resource groups, this manner indicates the association relationship between the RS resources, which can increase flexibility, and the second device can indicate various pairing relationships in a finer granularity.

[0153] Manner 2: The configuration information of the first RS resource includes a third field, and the third field indicates the second RS resource associated with the first RS resource. In other words, when the value of the third field indicates the first RS resource, it means that the first RS resource has an association relationship with the second RS resource.

[0154] Compared with indicating the association relationship between the RS resource groups, this manner indicates the association relationship between the RS resources, which can increase flexibility, and the second device can indicate various pairing relationships in a finer granularity.

[0155] Manner 3: The configuration information of the second RS resource includes a fourth field, and the fourth field indicates the first RS resource associated with the second RS resource. In other words, when the value of the fourth field indicates the first RS resource, it means that the first RS resource has an association relationship with the second RS resource.

[0156] Compared with indicating the association relationship between the RS resource groups, this manner indicates the association relationship between the RS resources, which can increase flexibility, and the second device can indicate various pairing relationships in a finer granularity.

[0157] Manner 4: The first RS resource and the second RS resource appear in the resource configuration signaling in pairs (for example, appear in one RS resource configuration signaling in pairs). Compared with directly indicating the association relationship between the RS resources, this manner can reduce signaling overhead.

[0158] Manner 5: The first RS resource and the second RS resource are indicated in the same measurement configuration signaling or the same reporting configuration signaling. Compared with directly indicating the association relationship between the RS resources, this manner can reduce signaling overhead.

[0159] Manner 6: The fifth field in the configuration information of the first RS resource group to which the first RS resource belongs and the sixth field in the configuration information of the second RS resource group to which the second RS resource belongs have the same value.

[0160] Here, the fifth field and the sixth field can be the same field in the configuration information of the first RS resource group and the configuration information of the second RS resource group, in other words, the fifth field and the sixth field are fields with the same meaning or the same function, or the fifth field and the sixth field are used to indicate the same type of information, and the fifth field and the sixth field are only distinguished for different configuration information corresponding to different RS resource groups.

[0161] Optionally, the fifth indication information used to indicate the first RS resource group in the foregoing embodiments can indicate the configuration information of the first RS resource group, or the fifth indication information can include the configuration information of the first RS resource group.

[0162] Optionally, the eleventh indication information used for indicating the second RS resource group in the foregoing embodiments can indicate configuration information of the second RS resource group, or the eleventh indication information can include the configuration information of the second RS resource group.

[0163] Compared with indicating the association relationship between RS resources, the association relationship between RS resource groups is indicated, and signaling overhead can be reduced.

[0164] Option 7: The configuration information of the first RS resource group to which the first RS resource belongs includes a seventh field, and the seventh field is used to indicate a second RS resource group associated with the first RS resource group, and the second RS resource group includes a second RS resource. In other words, when the value of the seventh field indicates the second RS resource group, it means that the first RS resource group and the second RS resource group have an association relationship.

[0165] Compared with indicating the association relationship between RS resources, the association relationship between RS resource groups is indicated, and signaling overhead can be reduced.

[0166] Option 8: The configuration information of the second RS resource group to which the second RS resource belongs includes an eighth field, and the eighth field is used to indicate a first RS resource group associated with the second RS resource group, and the first RS resource group includes a first RS resource. In other words, when the value of the eighth field indicates the first RS resource group, it means that the first RS resource group and the second RS resource group have an association relationship.

[0167] Compared with indicating the association relationship between RS resources, the association relationship between RS resource groups is indicated, and signaling overhead can be reduced.

[0168] Option 9: The first RS resource group and the second RS resource group appear in pairs in the resource configuration signaling (for example, appear in pairs in one RS resource configuration signaling). Compared with directly indicating the association relationship between RS resources or RS resource groups, this method can reduce signaling overhead.

[0169] Option 10: The first RS resource and the second RS resource are indicated simultaneously in the same measurement configuration signaling or the same reporting configuration signaling. Compared with directly indicating the association relationship between RS resources or RS resource groups, this method can reduce signaling overhead.

[0170] Option 11: Part of the resources in the second RS resource are the first RS resource. In this way, the first RS resource and the second RS resource are implicitly indicated to have an association relationship. Compared with directly indicating the association relationship between RS resource groups or RS resources, signaling overhead can be reduced.

[0171] An implementation example is as follows: the first indication information indicates the first RS resource, the first RS resource uses part of ports in the second RS resource, and / or the first RS resource uses part of time domain resources in the second RS resource, and / or the first RS resource uses part of frequency domain resources in the second RS resource, and it can be determined that the first RS resource is associated with the second RS resource.

[0172] For example, the second RS resource has K2 ports, and K1 (K1 < K2) ports in the K2 ports correspond to the first RS resource. For simplicity of description, it is assumed that K2 = 16 ports (port numbers are 0, 1, 2, 3, …, 15 respectively), and the ports (0, 4, 8, 12) in the second RS resource form the first RS resource.

[0173] In some embodiments, when it is indicated that the first RS resource group is associated with the second RS resource group, each RS resource in the first RS resource group is associated with each RS resource in the second RS resource group. In this way, the signaling overhead can be reduced.

[0174] In some embodiments, the above different manners can be combined for use, for example, one of manners 1-5 can be combined with one of manners 6-10, such as using one of manners 6-10 to indicate that the first RS resource group is associated with the second RS resource group, and using one of manners 1-5 to indicate one or more pairs of RS resources that are specifically associated. For another example, manners 2 and 3 can be combined, and for another example, manners 7 and 8 can be combined. These combined schemes can achieve a better trade-off between signaling overhead and flexibility.

[0175] In the embodiments of the present application, the first RS resource can be applied to obtain CSI or demodulate data and / or control information, and optionally, the CSI or the data and / or control information can also be obtained based on the first model. The application process of the first RS resource is exemplarily described below.

[0176] In some embodiments, the second device also sends second indication information to the first device. The second indication information is used by the first device to determine the first model. For example, the second indication information can indicate which AI model the first device uses, or which model to use, thereby improving the performance of the pass.

[0177] In some embodiments, the second indication information indicates the first identification information.

[0178] Optionally, the first identification information comprises an identification of the first model. The second indication information can directly indicate the first model, and the first device uses the first model to perform a corresponding subsequent operation (e.g., demodulation of a PDSCH, or demodulation of a PDCCH, or feedback of CQI information, or obtaining of channel information) based on the first RS resource. Specifically, the second indication information can indicate an identification or a number of the first model. Directly indicating the model is simple and direct in signaling design.

[0179] Optionally, the first identification comprises a consistency identification, which is used to determine whether network conditions are consistent, or indicates that network conditions are consistent. The consistency identification is an identification, or a number, or an associated ID, or a consistency ID. Through the consistency identification, direct indication of the model can be avoided, so that model-related information is not provided to a communication opposite end, e.g., some information of a UE-side model is not exposed to the network. In some examples, if the first device sees that the second indication information indicates the same content twice (e.g., the same identification, or the same number), the first device can assume that the RS resources corresponding to the two times of sending of the second indication information by the second device use the same configuration and / or network conditions (e.g., use the same antenna, and / or use the same precoding, etc.).

[0180] An example is that, when the first device receives the second indication information sent by the second device and the value of the second indication information is X, if there is a model (denoted as ModelX) that is trained using data corresponding to a second indication information with a value of X, the first device can assume or consider that this model (ModelX) is applicable to the current network configuration and / or network conditions, e.g., can use the model ModelX and the first RS to obtain a measurement result and / or a reporting result, or use the model ModelX and the first RS resource to report CSI (e.g., one or more of a PMI, a CQI, and an RI), or use the model ModelX and the first RS resource to demodulate a PDSCH / PDCCH.

[0181] Optionally, the second indication information can be transmitted through RRC signaling, or through MAC CE signaling, or through system information transmission, or through broadcast information transmission, or through DCI transmission.

[0182] For transmission of the second indication information:

[0183] An embodiment is that the second indication information and the first indication information are the same information; in this way, signaling overhead can be compressed.

[0184] An embodiment is that the second indication information is contained in the first indication information; in this way, signaling overhead can be compressed.

[0185] Another embodiment is that the second indication information and the first indication information are transmitted in the same signaling; in this way, the signaling overhead is smaller compared to transmitting the two through different signaling, and the flexibility is higher compared to the two being the same information or having a containing relationship.

[0186] Another embodiment is that the second indication information and the first indication information are transmitted through different signaling; in this way, the signaling design flexibility is better.

[0187] One embodiment is that the second indication information and the third indication information are the same information; in this way, the signaling overhead can be compressed.

[0188] One embodiment is that the second indication information is contained in the third indication information; in this way, the signaling overhead can be compressed.

[0189] Another embodiment is that the second indication information and the third indication information are transmitted in the same signaling; in this way, the signaling overhead is smaller compared to transmitting the two through different signaling, and the flexibility is higher compared to the two being the same information or having a containing relationship.

[0190] Another embodiment is that the second indication information and the third indication information are transmitted through different signaling; in this way, the signaling design flexibility is better.

[0191] One embodiment is that the second indication information and the fifth indication information are the same information; in this way, the signaling overhead can be compressed.

[0192] One embodiment is that the second indication information is contained in the fifth indication information; in this way, the signaling overhead can be compressed.

[0193] Another embodiment is that the second indication information and the fifth indication information are transmitted in the same signaling; in this way, the signaling overhead is smaller compared to transmitting the two through different signaling, and the flexibility is higher compared to the two being the same information or having a containing relationship.

[0194] Another embodiment is that the second indication information and the fifth indication information are transmitted through different signaling; in this way, the signaling design flexibility is better.

[0195] One embodiment is that the second indication information and the eleventh indication information are the same information; in this way, the signaling overhead can be compressed.

[0196] One embodiment is that the second indication information is contained in the eleventh indication information; in this way, the signaling overhead can be compressed.

[0197] Another embodiment is that the second indication information and the eleventh indication information are transmitted in the same signaling; in this way, the signaling overhead is smaller compared to transmitting the two through different signaling, and the flexibility is higher compared to the two being the same information or having a containing relationship.

[0198] In another embodiment, the second indication information and the eleventh indication information are transmitted through different signaling; in this way, the signaling design has better flexibility.

[0199] In some embodiments, the information transmission method further includes: the first device demodulating the data and / or control information based on the first RS resource.

[0200] Optionally, the first RS resource includes a first number (e.g., K1) of ports, and the first device can demodulate the data and / or control information corresponding to a second number (e.g., K2) of ports based on the first RS resource of the first number of ports.

[0201] One implementation example is that certain data and / or control information needs to be demodulated based on RS resources of K2 ports, in order to reduce RS overhead, the second device can configure the first device with a first RS resource including K1 (K1 < K2) ports, and the first device demodulates the data and / or control information based on the first RS resource. Optionally, the first device demodulates the data and / or control information based on the first model and the RS measurement result on the first RS resource, for example, inputs the data and / or control information and the RS measurement result into the first model to obtain the demodulation result.

[0202] In some embodiments, the information transmission method further includes: the first device reporting channel state information (CSI) of the second number of ports based on the first RS resource; wherein the first RS resource includes a first number of ports, the first number and the second number are both positive integers, and the first number is less than the second number. Optionally, the CSI includes one or more of the following: PMI information, channel matrix information, channel eigenvector information, CQI information, and RI information.

[0203] Optionally, the CQI information can be directly measured based on the first RS resource (e.g., not based on the AI model output result), or the CQI information can be directly measured based on the first RS resource and then increased by an adjustment value, which can be determined by the first device or according to the indication information issued by the second device.

[0204] Optionally, the CQI information can be directly obtained based on the AI model output result.

[0205] Optionally, the RI information can be directly measured based on the first RS resource (e.g., not based on the AI model output result), or the RI information can be directly measured based on the first RS resource and then increased by an adjustment value, which can be determined by the first device or according to the indication information issued by the second device.

[0206] Optionally, the RI information can be obtained directly based on the AI model output result.

[0207] In some embodiments, the second quantity is determined based on one or more of the following:

[0208] The second indication information, wherein the second indication information indicates the first identification information (optionally, the first identification information can include an identification of the first model and / or a consistency identification);

[0209] The first RS resource;

[0210] The fourth indication information, wherein the fourth indication information indicates a port number of the reported CSI;

[0211] The second RS resource.

[0212] Exemplarily, the manner of determining the second quantity can be one of the following options:

[0213] Option 1: The first device determines the second quantity according to the second indication information.

[0214] For example, in the training data of the first model, the model output result corresponding to the received second indication information taking value X is all corresponding to K2 ports. In detail, assuming that the input and output of the AI model in the training data are denoted as a and b respectively, a sample is a pair of a and b, denoted as (a, b). If the training data set contains part of the data corresponding to the second indication information taking value X, and the b in each sample (a, b) corresponding to the second indication information taking value X is corresponding to K2, then the first device can determine K2 when receiving the second indication information taking value X. In actual implementation, the signaling indication in the configuration corresponding to the training data does not necessarily have to be the same as the second indication information. As long as the value of the signaling indication in the configuration corresponding to the training data can have a corresponding relationship, such as a mapping relationship, with the second indication information, the first device can determine K2 based on the second indication information. In this example, the second indication information implies more constraints, and the signaling flexibility is low.

[0215] For another example, the second indication information indicates the first model, and the first terminal device determines K2 according to the first model.

[0216] Option 2: The first device determines the second quantity according to the first RS resource and the second indication information.

[0217] For example, in the training data of the first model, the model output corresponding to the received second indication information taking value X and corresponding to the first RS resource feature is all corresponding to K2 ports. A detailed example is that assuming the input and output of the AI model in the training data are denoted as a and b respectively, a sample is a pair of a and b, denoted as (a, b). If b in each (a, b) corresponding to the second indication information taking value X is corresponding to K2, and at least part of the features of a (such as the number of ports, and / or RS pattern, and / or RS time domain density, and / or RS frequency domain density, etc.) are the same as the first RS resource, then the first device can determine K2 according to the first RS and the received second indication information taking value X. In actual implementation, the signaling indication in the configuration corresponding to the training data does not necessarily have to be the same as the second indication information, as long as the value of the signaling indication in the configuration corresponding to the training data can have a corresponding relationship, such as a mapping relationship, with the second indication information, then the first device can determine K2 based on the first RS resource and the second indication information. In this example, the second indication information has less implicit constraints and higher signaling flexibility.

[0218] Option 3: The first device receives fourth indication information sent by the second device, and the first device determines the second quantity based on the fourth indication information.

[0219] One example is that the fourth indication information directly indicates the value of K2.

[0220] Option 4: The first device determines K2 according to the second RS resource.

[0221] It should be noted that in actual application, the second quantity is not limited to being determined by any one of the above options 1-4, and the second quantity can be determined based on any one or more of the second indication information, the first RS resource, the fourth indication information, and the second RS resource, for example, the second quantity can also be determined based on the features of the first RS resource and the features of the second RS resource, or determined based on the first RS resource, which is not limited in the present application.

[0222] In some embodiments, the first information is determined based on the first RS resource and the first model, and the first model is determined based on one or more of the following:

[0223] The second indication information; wherein the second indication information indicates the first identification information related to the first model;

[0224] The first RS resource;

[0225] The fourth indication information; wherein the fourth indication information indicates the port quantity of the reported CSI;

[0226] The second RS resource.

[0227] Exemplarily, the manner of determining the first model can be one of the following options:

[0228] Option A: The first device determines the first model according to the second indication information. For example, the first model is determined according to a model identifier / number indicated by the second indication information, or the first model is determined according to a consistency identifier indicated by the second indication information.

[0229] Option B: The first device determines the first model according to the first RS resource and the second indication information. For example, the first model is determined according to a characteristic (for example, a port number K1) of the first RS resource and a consistency identifier indicated by the second indication information.

[0230] Option C: The first device determines the first model according to the first RS resource and the fourth indication information. For example, the first model is determined according to a characteristic of model input information and a characteristic of output information, respectively, according to a characteristic (for example, a port number K1) of the first RS resource and a port number (for example, a second number K2) indicated by the fourth indication information.

[0231] Option D: The first device determines the first model according to the first RS resource, the second indication information, and the fourth indication information. For example, the first model is determined according to a characteristic of the first RS resource, a consistency identifier indicated by the second indication information, and a port number indicated by the fourth indication information.

[0232] Option E: The first device determines the first model according to the first RS resource and the second RS resource. For example, the first model is determined according to a characteristic (for example, a port number K1) of the first RS resource and a characteristic (for example, a port number K2) of the second RS resource.

[0233] Option F: The first device determines the first model according to the first RS resource, the second indication information, and the second RS resource.

[0234] It should be noted that in actual applications, the first model is not limited to being determined in any one of the options A-F, and the first model can be determined based on any one or more of the second indication information, the first RS resource, the fourth indication information, and the second RS resource, for example, can also be determined based on a characteristic of the first RS resource, and the present application does not limit this.

[0235] It can be seen that according to the embodiments of the present application, the first RS resource corresponding to the first number of ports can be used to obtain a channel measurement result or a demodulation result corresponding to the second number of ports, thereby reducing the RS overhead. In the embodiments of the present application, considering the reliability of communication, the performance of the above application manner of the first RS resource needs to be monitored, and therefore the first device reports information obtained based on the first RS resource. The specific reporting manner is exemplarily described below.

[0236] For the case that the first RS resource is used to obtain CSI, when the CSI is obtained based on the first RS resource (for example, when the CSI is inferred using the first model), the first device reports the CSI by sending signaling (which can be denoted as CSI reporting signaling).

[0237] Optionally, the second device can indicate the following one or more information to the first device by issuing indication information.

[0238] Reporting type related information; for example, indicating that the first device reports a channel matrix, or reports a PMI, or reports a channel eigenvector, and the like;

[0239] Reporting format related information;

[0240] Reporting data quantization method related information;

[0241] Information related to the reporting of RI limit; for example, the reported RI cannot exceed which range, the reported RI is less than or equal to which value, and the like;

[0243] Reporting environment related information; for example, indicating the quality of the reporting environment through SINR (Signal to Interference plus Noise Ratio), RSRP (Reference Signal Receiving Power), and the like;

[0244] Time / occasion information corresponding to the reporting information; for example, indicating that the first device reports the reporting information corresponding to which time in the future; and / or the reporting information within a future window; and / or the reporting information of how many times in the future; and / or the interval information between these future times.

[0245] The above information can be transmitted through any of the indication information in the foregoing embodiments (for example, the first indication information, and / or the second indication information, and the like), or can be transmitted through other indication information (for example, the twelfth indication information).

[0246] The first device reports the CSI obtained based on the first RS resource to the second device based on the first RS resource through a third reporting signaling. Optionally, the third reporting signaling can also carry the following one type or multiple types of information:

[0247] (1) Time information. The time information can be used to determine the time of reporting data.

[0248] Exemplarily, the time information can be timestamp information. For example, the timestamp information can be represented by a value calculated in time unit (e.g. in millisecond, microsecond, …); or for example, the timestamp information can be represented by SFN value, slot number, symbol number.

[0249] Exemplarily, the time information can indicate which time in the future the reporting result corresponds to. For example, for one reporting result, one information is carried to indicate which time in the future it corresponds to; for example, for multiple reporting results, one information is carried to indicate which time in the future a certain reporting information (e.g. the first reporting information) corresponds to, and the time in the future corresponding to other reporting information is determined according to fixed interval; for example, for multiple reporting results, which time in the future each reporting result corresponds to is determined according to its position, i.e. the first position corresponds to one time in the future, the second position corresponds to another time in the future, and the others are in turn.

[0250] (2) Information related to cell, e.g. cell ID.

[0251] (3) Position information; optionally, the position information can be used to judge the validity of the model.

[0252] (4) Speed related information; optionally, the speed related information can be used to judge the validity of the model.

[0253] For example, the speed related information can correspond to the speed of the first device at the time of reporting sample.

[0254] (5) Information related to the reliability of the reporting result; optionally, the information related to the reliability of the reporting result can be used to judge the validity of the AI model.

[0255] For example, the information related to the reliability of the reporting result can include the confidence of the reporting result.

[0256] (6) Information related to the estimation error of the reporting result; optionally, the information related to the estimation error of the reporting result can be used to judge the validity of the AI model.

[0257] For example, the information related to the estimation error of the reporting result can include the variance information of the reporting result.

[0258] (7) Information related to wireless environment; optionally, the information related to wireless environment can be used to judge the validity of the AI model.

[0259] For example, the information related to wireless environment can include the characteristics of the current channel, and / or the type of the current channel, and / or SINR, and / or RSRP.

[0260] Optionally, the third reporting signaling can be transmitted through a PUCCH, and / or transmitted through a PUSCH, and / or transmitted through a MAC CE signaling.

[0261] Optionally, the third reporting signaling can be transmitted through a UCI, and / or transmitted through a MAC CE signaling.

[0262] The following is an exemplary description of monitoring the performance of the first RS resource related algorithm / model.

[0263] In an implementation manner, the first device reports the first information based on the first RS resource and the second RS resource through the first reporting signaling.

[0264] Optionally, the information transmission method further includes: the second device sending sixth indication information. Correspondingly, the first device receives the sixth indication information. The sixth indication information indicates the first device to report the first information through the first reporting signaling.

[0265] Optionally, the sixth indication information indicates the first device to report the first information based on the first RS resource and the second RS resource through the first reporting signaling. Through the sixth indication information, it can be more flexible to indicate which information related to performance monitoring is reported by the first device, and the second device can obtain better controllability.

[0266] In some embodiments, the sixth indication information indicates one or more of the following:

[0267] (1) Threshold information related to the first information; optionally, the first device determines the information reported in the first reporting signaling based on the threshold information. For example, the threshold information can be an error threshold of the information obtained by the first device based on the first RS resource (optionally, also based on the first model); for another example, the threshold information can be a threshold of the difference between the CSI obtained based on the first RS resource (optionally, also based on the first model) and the CSI obtained based on the second RS resource.

[0268] (2) Information type in the first information; optionally, the information type can be understood as information related to the reporting content / reporting result type.

[0269] (3) Information related to the reporting format.

[0270] (4) Information related to the quantization method and / or quantization parameter.

[0271] (5) Information related to the first condition; optionally, the first condition can be a condition for determining whether to report, and the information related to the first condition can be used by the first device to determine the first condition, for example, the information related to the first condition can be configuration information of the first condition.

[0272] Optionally, the sixth indication information can be transmitted by DCI signaling, or MAC CE signaling, or RRC signaling, or system message, or broadcast message.

[0273] In some embodiments, the first information comprises a first result obtained based on the first RS resource. For example, the first result can comprise a channel measurement result (e.g., CSI, channel matrix information, channel eigenvector, etc.) obtained based on the first RS resource; for another example, the first result can comprise a result of demodulation based on the information obtained based on the first RS inference (e.g., accuracy, error rate, etc.).

[0274] In some embodiments, the first information further comprises a second result obtained based on the second RS resource. For example, the second result can comprise a channel measurement result (e.g., CSI, channel matrix information, channel eigenvector, etc.) obtained based on the second RS resource; for another example, the second result can comprise a result of demodulation based on the information obtained based on the second RS inference (e.g., accuracy, error rate, etc.).

[0275] The first device reports the first result based on the first RS resource and the result based on the second RS resource to the second device by the first reporting signaling, and the second device can judge the performance of the first RS resource related algorithm / model by itself, so that the network has more flexible processing.

[0276] In some embodiments, the first information is obtained based on the first result and the second result; the first result is obtained based on the first RS resource, and the second result is obtained based on the second RS resource. That is, the first device does not report the first result and the second result respectively (including reporting by the same signaling or reporting in different signaling), but obtains a first information based on the first result and the second result, and then reports the first information to the second device, which can reduce the signaling overhead.

[0277] In some embodiments, the first information comprises difference information between the first result and the second result.

[0278] Optionally, the difference information is one or more of difference value information, mean of difference value information, variance of difference value information, mean-square error (MSE) of difference value information, etc. For example, the first information comprises difference value information between CSI information obtained based on the first RS resource and CSI information obtained based on the second RS resource, and / or mean of difference value information, and / or variance. For another example, the first information comprises MSE information of the difference between CSI information obtained based on the first RS resource and CSI information obtained based on the second RS resource.

[0279] The first information comprises difference information between the first result and the second result, which can reduce the overhead of feedback signaling.

[0280] In some embodiments, the first information comprises event information triggered based on the first result and the second result.

[0281] Optionally, the event information is triggered in a case where it is determined that a certain condition is satisfied based on the first result and the second result.

[0282] In some embodiments, the event information indicates one or more of:

[0283] a difference between the first result and the second result satisfies a first condition;

[0284] based on the first result and the second result, the first device suggests to replace one or more of the first RS resource, a configuration of the first RS resource, and the first model; and the first information is obtained based on the first model.

[0285] Exemplarily, the first information comprises indication information of a first event, indicating that the first event occurs, the first event representing that a difference between the first result obtained based on the first RS resource (e.g., a result obtained based on the first model and the first RS resource) and the second result obtained based on the second RS resource satisfies a first condition.

[0286] In some embodiments, the first condition is determined based on sixth indication information received by the first device or a predetermined rule (e.g., determined according to a network configuration or determined according to a rule predefined according to a protocol). An example is that the first condition is determined based on threshold information in the sixth indication information, the first condition being, for example, that difference information between the first result and the second result is greater than a threshold value indicated by the threshold information.

[0287] Exemplarily, the first information comprises indication information of a second event, indicating that the second event occurs. For example, the second event represents that, based on the first result and the second result, the first device suggests to replace one or more of the first RS resource, a configuration of the first RS resource, and the first model. For example, the first device determines that a difference between the first result obtained based on the first RS resource (e.g., a result obtained based on the first model and the first RS resource) and the second result obtained based on the second RS resource satisfies a first condition, in which case the first device suggests to replace one or more of the first RS resource, a configuration of the first RS resource, and the first model, and the first device sends first reporting signaling, the first reporting signaling comprising the first information, indicating that the second event occurs.

[0288] In an implementation manner, the first device reports the first result through first reporting signaling and reports the second result through second reporting signaling.

[0289] Specifically, in some embodiments, the first information in the first reporting signaling includes a first result obtained based on the first RS resource. The information transmission method further includes: the first device sending second reporting signaling. Correspondingly, the second device receives the second reporting signaling. The second reporting signaling includes a second result obtained based on a second RS resource.

[0290] Optionally, before the above steps, the information transmission method further includes: the second device sending seventh indication information. Correspondingly, the first device receives the seventh indication information. The seventh indication information indicates that the first device reports the first result obtained based on the first RS resource through the first reporting signaling.

[0291] Optionally, before the above steps, the information transmission method further includes: the second device sending eighth indication information. Correspondingly, the first device receives the eighth indication information. The eighth indication information indicates that the first device reports the second result obtained based on the second RS resource through the second reporting signaling.

[0292] By using different indication signaling and independently reporting the related results respectively, the signaling design flexibility can be increased, and the standardization workload can be reduced.

[0293] Optionally, the seventh indication information can be transmitted through DCI signaling, or MAC CE signaling, or RRC signaling, or system message, or broadcast message.

[0294] Optionally, the eighth indication information can be transmitted through DCI signaling, or MAC CE signaling, or RRC signaling, or system message, or broadcast message.

[0295] Optionally, the third reporting signaling and / or the first reporting signaling and / or the second reporting signaling is transmitted through PUCCH, or MAC CE signaling, or RRC signaling, or UCI.

[0296] Optionally, the third reporting signaling is transmitted through UCI (for example, PUCCH), and the first reporting signaling / second reporting signaling is transmitted through MAC signaling; or the third reporting signaling is transmitted through UCI (for example, PUCCH), and the first reporting signaling / second reporting signaling is transmitted through RRC signaling; or the third reporting signaling is transmitted through MAC CE signaling, and the first reporting signaling / second reporting signaling is transmitted through MAC CE signaling; or the third reporting signaling is transmitted through MAC CE signaling, and the first reporting signaling / second reporting signaling is transmitted through RRC signaling.

[0297] In some embodiments, the first reporting signaling further includes one or more of the following information related to the first information:

[0298] (1) Time information.

[0299] Exemplarily, the time information can be timestamp information. For example, the timestamp information can be represented by a value calculated in time unit (e.g. in millisecond, microsecond, …); or for example, the timestamp information can be represented by SFN value, slot number, symbol number.

[0300] (2) Information related to cell, e.g. cell ID.

[0301] (3) Position information; optionally, the position information can be used to judge the validity of the model.

[0303] For example, the speed related information can correspond to the speed of the first device at the time of the first information.

[0304] (5) Reliability related information; optionally, the reliability related information of the reported result can be used to judge the validity of the AI model.

[0305] For example, the reliability related information of the reported result can include the confidence of the reported result.

[0306] (6) Error related information; optionally, the error related information can be used to judge the validity of the AI model.

[0307] For example, the error related information of the reported result can include the variance information of the reported result.

[0311] Exemplarily, the time information can be timestamp information. For example, the timestamp information can be represented by a value calculated in time unit (e.g. in millisecond, microsecond, …); or for example, the timestamp information can be represented by SFN value, slot number, symbol number.

[0312] (2) Information related to cell, e.g. cell ID.

[0313] (3) Position information; optionally, the position information can be used to determine the validity of the model.

[0319] For example, the estimated error-related information of the second result can include variance information of the reported result.

[0320] (7) Wireless environment-related information; optionally, the wireless environment-related information can be used to determine the validity of the AI model.

[0321] Optionally, the relationship between the Y1th indication information and the Y2th indication information has different options, where the Y1th indication information and the Y2th indication information respectively represent any two of the first indication information, the second indication information, the third indication information, the fourth indication information, the fifth indication information, the sixth indication information, the seventh indication information, the eighth indication information, the ninth indication information, the tenth indication information, the eleventh indication information, and the twelfth indication information:

[0322] In one embodiment, the Y1th indication information and the Y2th indication information are the same information.

[0323] In one embodiment, the Y1th indication information is contained in the Y2th indication information.

[0324] In another embodiment, the Y1th indication information and the Y2th indication information are transmitted in the same signaling.

[0325] In another embodiment, the Y1th indication information and the Y2th indication information are transmitted through different signaling.

[0326] The above scheme can be directly extended to the relationship between more different indication information, which will not be repeated here.

[0327] In some embodiments, the information transmission method further comprises: the second device sending ninth indication information. Correspondingly, the first device receives the ninth indication information; wherein the ninth indication information is a response of the first reporting signaling or the second reporting signaling, and / or the ninth indication information indicates a channel measurement configuration, and / or the ninth indication information indicates a fallback operation, and / or the ninth indication information indicates a new model.

[0328] Optionally, when the second device receives the first reporting signaling and / or the second reporting signaling, it is considered that the performance based on the first RS resource is not good, and then the second device can indicate the first device to perform a new operation through the ninth indication information, such as indicating a new channel measurement configuration (such as indicating a new first RS resource or indicating a new first model, etc.) or indicating a fallback operation.

[0329] Optionally, when the second device receives the first reporting signaling and / or the second reporting signaling, it is known that the first device considers that the performance based on the first RS resource is not good, or it is known that the first device suggests to replace the first RS resource (or replace the configuration of the first RS resource), or it is known that the first device suggests to replace the first model, and then the second device can indicate the first terminal device to perform a new operation (such as indicating a new first RS resource, indicating a new first model, etc.) or indicating a fallback operation through the ninth indication information.

[0330] In some embodiments, the information transmission method further comprises: the first device sending first capability information. Correspondingly, the second device receives the first capability information. Wherein the first capability information is used to indicate the capability of the first device to report the CSI of the second number of ports based on the RS resource of the first number of ports, or the capability of the first device to demodulate the data and / or control information of the second number of ports based on the RS resource of the first number of ports, wherein the first number and the second number are both positive integers, and the first number is less than the second number.

[0331] In some embodiments, the first capability information is carried through UE capability signaling or terminal assistance information.

[0332] Wherein, through the UE capability signaling, it can be avoided to repeatedly report the UE capability in different cells.

[0333] Optionally, the first capability information is transmitted through RRC signaling or MAC CE.

[0334] In some embodiments, the first capability information is reported for one of the following: frequency band, frequency band combination, each frequency band in the frequency band combination, each carrier of each frequency band in the frequency band combination, frequency band range, and the first device.

[0335] Specifically, the following optional ways can be provided:

[0336] Optionally, the first capability information is reported per band (i.e., different bands can be independently reported).

[0337] Different bands are independently reported, which can give the first device greater freedom of implementation, for example, the first device can support this function on a certain band or bands, and not support this function on other bands, so that more terminal devices can support this new function. Optionally, the first capability information is reported per band combination.

[0338] Different band combinations are independently reported, which can give the first device greater freedom of implementation, for example, the first device can not support this function under a certain band combination, but support this function under another band combination, so that more terminal devices can support this new function.

[0339] Optionally, the first capability information is reported per band per band combination (i.e., different bands in different band combinations can be independently reported). Different band combinations are independently reported, which can give the first device greater freedom of implementation, for example, the first device can not support this function under a certain CA, but support this function under another CA combination, so that more terminal devices can support this new function.

[0340] Optionally, the first capability information is reported per CC per band per band combination (i.e., different CCs in different bands in different band combinations can be independently reported, or FSPC). Different band combinations are independently reported, and different CCs on a band can also be independently reported, which can give the first device greater freedom of implementation, so that more terminal devices can support this new function.

[0341] Optionally, the first capability information is reported per frequency range (FR) (i.e., different FRs can be independently reported, per FR, i.e., FR1 and FR2 are independently reported). Independent reporting of different FRs can give the first device greater freedom of implementation, for example, the first device does not support this function in low frequency (FR1), but supports this function in FR2 (high frequency), so that more terminal devices can support this new function.

[0342] Optionally, the first capability information is reported for the first device, or reported for the UE (i.e., per UE, if the UE reports this capability, it can support this capability on all frequency bands). This approach can reduce the signaling overhead of terminal capability reporting.

[0343] In some embodiments, the information transmission method further includes: the first device sending second capability information. Correspondingly, the second device receives the second capability information. The second capability information is used to indicate that the first device reports the capability of CSI corresponding to a second number of ports based on RS resources of a first number of ports, or the capability of the first device to demodulate data and / or control information corresponding to the second number of ports based on RS resources of the first number of ports, wherein the first number and the second number are positive integers, and the first number is less than the second number.

[0344] In some embodiments, the second capability information is carried through terminal assistance information (UE assistance information). By carrying the second capability information through the terminal assistance information, the flexibility is better, and the first device can indicate its own capability according to the current situation (e.g., computing resources, power consumption, power).

[0345] Optionally, the second capability information is transmitted through RRC signaling or MAC CE.

[0346] In some embodiments, the second capability information is reported for a serving cell.

[0347] Optionally, when the first device reports the second capability information, the second capability information is not carried with service cell indication information (i.e., it does not indicate which specific service cell or service cells), and the second capability information is applicable to the serving cell currently transmitting the second capability information or all serving cells of the first device.

[0348] Optionally, when the first device reports the second capability information, the second capability information is carried with service cell indication information (e.g., it can indicate one service cell or multiple service cells), and the second capability information is applicable to the service cell indicated by the service cell indication information. This approach has better flexibility, and can indicate which service cells have these capabilities according to the current situation (e.g., computing resources, power consumption, power).

[0349] The indication or configuration of the second device in the foregoing embodiments needs to match the capability reported by the first device. For example, after receiving the first capability information and / or the second capability information reported by the first device, the second device can indicate the first device to perform measurement and / or reporting according to the first RS resource, or to perform demodulation of data or control information.
