[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 (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 are not utilized, and by utilizing these new dimensions, the RS overhead can be further reduced while ensuring the reception performance.

[0063] In order to fully exploit and utilize the capabilities of new algorithms / methods, it is often necessary to collect certain data for algorithm development and optimization. The embodiments of the present application can give specific scheme design for such a case (data collection and reporting). For example, by using the embodiments of the present application, the terminal device performs measurement and collects data (optionally, the terminal can also transmit the collected data to the network), and these data can be used to train the AI model, and the subsequent transmission between the terminal device and the network can use the trained AI model to improve performance. It should be pointed out that the above is only an exemplary application mode of the embodiments of the present application, and the embodiments of the present application can also have other application modes, therefore, the embodiments of the present application are not limited to a specific application mode.

[0064] It should be understood that the technical solutions of the embodiments of the present application can be applied to a centimeter wave communication scenario, can be used in a millimeter wave communication scenario, can be applied to a low frequency communication scenario, and can be applied to other various communication scenarios.

[0065] FIG. 2 is a schematic flowchart of a resource configuration method according to an embodiment of the present application. The method can be optionally applied to the system shown in FIG. 1, but is not limited thereto. The method comprises:

[0066] S210, the first device receives first indication information; wherein the first indication information indicates first RS resources; the number of resources of the first RS resources is less than the number of resources of the second RS resources; the first RS resources and the second RS resources are RS resources of the same type.

[0067] Optionally, the device type of the first device can be a terminal device. The first indication information can be sent by 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. In order to facilitate description and concise description, in some examples of the present specification, the introduction of the technical solutions will be taken as an example of terminal device and network communication, and it can be understood that the introduced technical solutions can also be used for terminal device and terminal device communication, and the generalization of this application scenario can be thought of by those skilled in the art, which should be covered within the protection scope of the present application.

[0068] In the embodiments of the present application, the RS transmits on the resources corresponding to the RS resources of the RS, and thus, the RS can be represented by the RS resources corresponding to the RS. It can be understood that the configuration / indication of the RS resources can also be understood as the configuration / indication of the RS.

[0069] In the embodiments of the present application, the first indication information indicates the first RS resources, in other words, the first indication information is used by the first device to determine the first RS resources, and accordingly, the first device can determine the first RS resources according to the first indication information. In addition, the first device can determine the second resources, for example, the first indication information also indicates the second RS resources, or the second device indicates the second RS resources through other indication information.

[0070] In the embodiments of the present application, the number of resources of the first RS resources is less than the number of resources of the second RS resources. That is, the first device can determine a pair of RS resources with different numbers of resources. The first RS resources and the second RS resources are RS resources of the same type, for example, the first RS resources and the second RS resources are resources of DMRS or CSI-RS, etc. Since the first RS resources and the second RS resources are RS resources of the same type, and the number of resources of the first RS resources is less than the number of resources of the second RS resources, the first device can collect data corresponding to RS resources of the same type with different numbers of resources, so as to optimize the related communication algorithm or model by using the data, so as to reduce the requirement for the number of resources of the RS resources of the same type, and help to reduce the RS overhead.

[0071] 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:

[0072] S310, the second device sends first indication information; wherein the first indication information indicates the first RS resources; the number of resources of the first RS resources is less than the number of resources of the second RS resources; the first RS resources and the second RS resources are RS resources of the same type.

[0073] According to the embodiments of the present application, the first device can determine the first RS resources and the second RS resources containing different numbers of resources based on the indication of the second device, and the first RS resources and the second RS resources are RS resources of the same type, so that the application of the RS resources of the same type can be optimized based on the first RS resources and the second RS resources, which lays a foundation for reducing the complexity and improving the receiving performance of the receiving end by using a small amount of RS resources, and thus helps to reduce the RS overhead.

[0074] In some embodiments, the first RS resources and the second RS resources are resources of CSI-RS or DMRS.

[0075] As an example, the first RS resource is a CSI-RS resource, and the second RS resource is a CSI-RS resource.

[0076] As an example, the first RS resource is a DMRS, and the second RS resource is a DMRS. The DMRS can help to demodulate data and / or control signaling, but it is also essentially to obtain channel information (also can be called equivalent channel), so the DMRS can also be understood as used for channel measurement.

[0077] As other examples, the first RS resource and the second RS resource can also be other types of RS resources (i.e., non-CSI-RS resources or non-DMRS resources).

[0078] Optionally, the first indication information can be transmitted through radio resource control (RRC) signaling, or through media access control element (MAC CE) signaling, or through system information (System Information) transmission, or through broadcast information (Broadcast information) transmission.

[0079] In some embodiments, the first RS resource and / or the second RS resource is used for channel measurement. Illustratively, the first RS resource is used for channel measurement, or the second RS resource is used for channel measurement, or the first RS resource and the second RS resource are respectively used for channel measurement.

[0080] In some embodiments, the channel measurement of the first RS resource and / or the second RS resource is used to obtain channel state information (CSI), or is used to demodulate data and / or control information.

[0081] In some embodiments, the CSI includes one or more of the following information: channel matrix information, channel eigenvector information, precoding matrix indicator (PMI) information, channel quality indicator (CQI) information, rank indicator (RI) information.

[0082] Optionally, the information obtained or reported based on the first RS resource and the information obtained or reported based on the second RS resource can be the same or different.

[0083] For example, the first device can obtain a channel (or referred to as a channel matrix), and / or a characteristic vector corresponding to the channel (also referred to as an eigen vector of the channel), and / or a processing of the channel (for example, information of the channel in an angle-delay domain), and / or a PMI corresponding to the channel, and / or an RI, based on the measurement of the RS on the first RS resource.

[0084] For another example, the first device can demodulate data and / or control information based on the measurement of the RS on the first RS resource.

[0085] For another example, the first device reports the channel matrix information based on both the first RS resource and the second RS resource; or, the first device reports the channel matrix information and the eigen vector information based on the first RS resource and the second RS resource respectively.

[0086] For another example, the first device reports the eigen vector information based on both the first RS resource and the second RS resource.

[0087] For another example, the first device reports the eigen vector information and the channel matrix information based on the first RS resource and the second RS resource respectively.

[0088] For another example, the first device reports the PMI information based on both the first RS resource and the second RS resource.

[0089] For another example, the first device reports the PMI information and the channel matrix information based on the first RS resource and the second RS resource respectively.

[0090] For another example, the first device reports the channel matrix information and the PMI information based on the first RS resource and the second RS resource respectively.

[0091] Optionally, the second device can indicate the measurement metric or the reporting metric to the first device through signaling (referred to as sixth indication information). That is, the sixth indication information indicates a specific measurement metric (or referred to as measurement quantity) or a specific reporting metric (or referred to as reporting quantity), so that the network optimization can be more flexible.

[0092] For transmission of the sixth indication information:

[0093] In one embodiment, the sixth indication information and the first indication information are the same information; in this way, the signaling overhead can be compressed.

[0094] In one embodiment, the sixth indication information is contained in the first indication information; in this way, the signaling overhead can be compressed.

[0095] Another embodiment is that the sixth indication information and the first 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.

[0096] Another embodiment is that the sixth indication information and the first indication information are transmitted through different signaling; in this way, the signaling design flexibility is better.

[0097] In some embodiments, the first RS resource and / or the second RS resource is used to obtain training data. For example, it can be used to obtain training data of an algorithm; for another example, it can be used to obtain training data of an AI model.

[0098] In an actual system, the results obtained by the first device based on the first RS resource and the second RS resource can have many uses. For example, it can be used to train an AI model. At this time, the result obtained based on the first RS resource corresponds to the input of the AI model; the result obtained based on the second RS resource corresponds to the label or the output of the AI model. For another example, it can be used to optimize a communication algorithm, such as optimizing a filter (or matrix) therein. These results can be executed by the first device (such as a first terminal device) to perform the above-mentioned applications (such as training an AI model or optimizing a communication algorithm), or by the second device (such as a first network device) to perform the above-mentioned applications, or by a server to perform the above-mentioned applications. The server can be third-party, or a terminal user, or a terminal device vendor (UE vendor), or an operator, or a network device vendor.

[0099] It should be noted that in the embodiments of the present application, one information (denoted as In) corresponds to the input of the AI model, or In is the input of the AI model, which can be one of the following cases: In is directly used as the input of the AI model; In is processed and then used as the input of the AI model (i.e., the input of the AI model is based on In).

[0100] Similarly, in the embodiments of the present application, one information (denoted as Out) corresponds to the output of the AI model, or Out is the output of the AI model, which can be one of the following cases: Out is the direct output of the AI model; the output of the AI model is processed to obtain Out.

[0101] The above-mentioned In and Out can be any information corresponding thereto hereinafter, and for the sake of brevity, the cases of In and Out will not be described again hereinafter.

[0102] In some embodiments, the resource configuration method further includes: the second device sends second indication information. Correspondingly, the first device receives the second indication information. For example, the second indication information indicates that the network conditions remain consistent.

[0103] Optionally, the second indication information can indicate that the training data and the AI model actually use corresponding relevant network conditions / configurations are consistent.

[0104] Optionally, the second indication information can indicate an identity or a number. In some examples, if the first device sees that the second indication information indicates the same content (e.g., the same identity or the same number), assuming that the second indication information corresponds to the first time second indication information and the second time second indication information respectively, the first device can assume that the network uses the same configuration or condition (e.g., uses the same antenna, and / or uses the same precoding, etc.) for the first RS resource corresponding to the two times of the second indication information; optionally, the first device can also assume that the network uses the same configuration or condition (e.g., uses the same antenna, and / or uses the same precoding, etc.) for the second RS resource corresponding to the two times of the second indication information. An embodiment is that the first device receives the second indication information taking value X when collecting data for training an AI model. When this model is used, the device (which can be the first device or other devices, e.g., other terminal devices, the first device can also give other terminal devices to use this model after collecting data to train the model) receiving the second indication information finds that the network sends the second indication information taking value X, and then the device can assume that this AI model is suitable for the current network configuration.

[0105] 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.

[0106] For transmission of the second indication information:

[0107] An embodiment is that the second indication information and the first indication information are the same information; in this way, the signaling overhead can be compressed.

[0108] An embodiment is that the second indication information is contained in the first indication information; in this way, the signaling overhead can be compressed.

[0109] 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 than that of transmitting them through different signaling, and the flexibility is higher than that of the two being the same information or having a containing relationship.

[0110] 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.

[0111] In some embodiments, the first RS resource has a smaller number of resources in a first dimension than the second RS resource, the first dimension including one or more of port, space, time, and frequency.

[0112] For example, the first dimension includes port, or the first dimension includes space, and the resources in the space include port, then the first RS resource has a smaller number of ports than the second RS resource. For another example, the first dimension includes time, then the first RS resource has a smaller number of resources in time than the second RS resource. For another example, the first dimension includes frequency, then the first RS resource has a smaller number of resources in frequency than the second RS resource.

[0113] It should be noted that in the embodiments of the present application, the first RS resource has a smaller number of resources than the second RS resource, which can include that the first RS resource has a smaller number of resources than the second RS resource in the same range. For example, the first RS resource has a smaller number of resources than the second RS resource in the same frequency range (such as one or more RBs), i.e., the first RS resource has a smaller frequency density than the second RS resource. For another example, the first RS resource has a smaller number of resources than the second RS resource in the same time range (such as one slot or one subframe), i.e., the first RS resource has a smaller time density than the second RS resource.

[0114] There can be different implementation methods for the first RS resource and the second RS resource, and some examples are given below.

[0115] Example 1: The first RS resource has a smaller number of ports (K1) than the second RS resource (K2).

[0116] 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.

[0117] A typical application scenario is a deployment scenario with a large number of base station antennas (e.g., a wireless communication system in the centimeter wave frequency band). If the network needs the UE to measure all the ports (e.g., based on the second RS resource for measurement), and then the UE feeds back the precoding matrix indication (PMI) according to the measurement results, and possibly the Rank and / or CQI 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 (e.g., 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%).

[0118] In order to complete the above prediction work, some corresponding data is often needed to extract statistical characteristics, or to train an AI model, or to train a machine learning algorithm. It can be understood that in actual 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, a data pair needs to be obtained: information based on K1 ports (e.g., 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 (e.g., 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 applications, multiple 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 based on the two pieces of information and the relationship, and these collected data (i.e., multiple samples) can be used for the development and research of the prediction scheme. Alternatively, the network can separately indicate the first RS resource and the second RS resource to the UE, and the UE obtains the above-mentioned sample (i.e., the data pair) based on the network indication and reports it to the network, and then the network can collect the data (i.e., multiple samples) for the development and research of the prediction scheme.

[0119] In actual systems, the correspondence between the ports of the first RS resource and the ports of the second RS resource can have different options:

[0120] Option 1: The correspondence between the ports of the first RS resource and the ports of the second RS resource is determined 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.

[0121] 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.

[0122] Example 2: The frequency domain density of the first RS resource is less than the frequency domain density of the second RS resource. The complete channel can be measured by the RS with lower frequency domain density, which can reduce the RS overhead, increase the transmission resources, and improve the system performance.

[0123] 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.

[0124] 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.

[0125] 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 CQI 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%).

[0126] In order to complete the above prediction work, some corresponding data is often needed to extract statistical characteristics, or to train an AI model, or to train a 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, 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 respectively indicate the first RS resource and the second RS resource to the UE, and the UE obtains the above-mentioned sample (i.e., the data pair) based on the network indication and reports to the network. Then the network can collect data (i.e., a plurality of samples) for the development and research of the prediction scheme.

[0127] 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 through the RS with lower time-domain density, the RS overhead can be reduced, the resources for transmission can be increased, and the system performance can be improved.

[0128] 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.

[0129] 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.

[0130] 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 time-domain density, 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, and may also feed back the Rank and / or CQI information, etc. according to the measurement results. For another example, the UE demodulates data and / or control signaling according to the downlink measurement signals.

[0131] In an actual system, the network needs to frequently transmit downlink measurement signals, so the overhead of the downlink measurement RS is large. One way is to measure a RS resource with a smaller time-domain density (such as measuring based on the first RS resource), and then predict (or estimate, or speculate) a 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 by 1-TD-Density1 / TD-Density2. If TD-Density1 = 1 and TD-Density2 = 4, the downlink measurement RS overhead can be reduced by 3 / 4 (75%).

[0132] In order to complete the above prediction work, some corresponding data is often needed to extract statistical characteristics, or to train an AI model, or to train a machine learning algorithm. It can be understood that in actual application, various 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 obtained based on the low-time-domain-density downlink measurement RS (for example, channel information or PMI or other information obtained based on the first RS resource measurement), denoted as data A, and information obtained based on the high-time-domain-density downlink measurement RS (for example, channel information or PMI or other information obtained based on the second RS resource measurement), denoted as data B. We call such a pair of data a sample (data A, data B). In actual application, multiple 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 above-mentioned sample (i.e., the data pair) can be obtained based on the information of the two and the relationship, and these collected data (i.e., multiple samples) can be used for the development and research of the prediction scheme. Alternatively, the network can respectively indicate the first RS resource and the second RS resource to the UE, and the UE reports the above-mentioned sample (i.e., the data pair) to the network based on the network indication, and then the network can collect the data (i.e., multiple samples) for the development and research of the prediction scheme.

[0133] 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:

[0134] 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);

[0135] The port number (K1) of the first RS resource is less than the port number (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);

[0136] 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);

[0137] 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, 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).

[0138] The specific details of the above combination scheme will not be repeated.

[0139] The indication manner of the first RS resource and the second RS resource will be exemplarily described below.

[0140] In some embodiments, the first indication information further indicates the second RS resource associated with the first RS resource. That is, the first indication information indicates the first RS resource and the second RS resource, and the first device determines the first RS resource and the second RS resource according to the first indication information.

[0141] Exemplarily, in the scenario of collecting samples / data by the first device, the first device receives the first indication information sent by the second device, and the first device determines the first RS resource and the second RS resource according to the first indication information. In this scenario, the first RS resource is associated with the second RS resource, so that the first device collects paired samples based on the associated first RS resource and second RS resource. It can be understood that in the scenario of collecting samples / data by the second device, the above-mentioned embodiments can also be adopted, and the first indication information is used to indicate the first RS resource and the second RS resource, and the present application does not limit this.

[0142] In some embodiments, the resource configuration method further comprises: the second device sends third indication information. Correspondingly, the first device receives the third indication information. Wherein, the third indication information indicates the second RS resource. That is, the second device indicates the first RS resource through the first indication information, and indicates the second RS resource through the third indication information, and the first RS resource and the second RS resource are indicated respectively.

[0143] Exemplarily, in the scenario of collecting samples / data by the second device, the first device receives the first indication information sent by the second device, and the first device determines the first RS resource according to the first indication information; the first device receives the third indication information sent by the second device, and the first device determines the second RS resource according to the third indication information. In this scenario, the first device determines the corresponding RS resource according to the indication of the second device, and reports the results corresponding to different RS resources respectively according to the indication of the second device, and the second device can not need to indicate the association relationship between the first RS resource and the second RS resource to the first device, thereby reducing the indication overhead. It can be understood that in the scenario of collecting samples / data by the first device, the second device can also adopt the above-mentioned embodiments, and the second device can indicate that the second RS resource indicated by the third indication information has an association relationship with the first RS resource indicated by the first indication information through additional information.

[0144] The relationship between the first indication information and the third indication information can have different options:

[0145] Option 1: the third indication information is contained in the first indication information; in this way, the signaling overhead can be compressed.

[0146] Option 2: the third indication information and the first 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.

[0147] Option 3: the third indication information and the first indication information are transmitted through different signaling; in this way, the signaling design flexibility is better.

[0148] In some embodiments, the first RS resource can be one RS resource in the first RS resource group. Optionally, the first device receives seventh indication information sent by the second device, and the first device determines the first RS resource group according to the seventh indication information.

[0149] Among them, there can be different options for the relationship between the seventh indication information and the first indication information.

[0150] One embodiment is that the seventh indication information and the first indication information are the same information; in this way, the signaling overhead can be compressed.

[0151] One embodiment is that the seventh indication information is contained in the first indication information; in this way, the signaling overhead can be compressed.

[0152] Another embodiment is that the seventh indication information and the first 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.

[0153] Another embodiment is that the seventh indication information and the first indication information are transmitted through different signaling; in this way, the signaling design flexibility is better.

[0154] Similarly, in some embodiments, the second RS resource can be one RS resource in the second RS resource group. Optionally, the above-mentioned seventh indication information can also be used to indicate the second RS resource group; or the first device receives eighth indication information sent by the second device, and the first device determines the second RS resource group according to the eighth indication information.

[0155] Among them, there can be different options for the relationship between the eighth indication information and the first indication information / third indication information (information used to indicate the second RS resource).

[0156] One embodiment is that the eighth indication information and the first indication information / third indication information are the same information; in this way, the signaling overhead can be compressed.

[0157] In an embodiment, the eighth indication information is included in the first indication information / third indication information; in this way, the signaling overhead can be compressed.

[0158] In another embodiment, the eighth indication information and the first indication information / third indication information are transmitted in the same signaling; in this way, the signaling overhead is smaller than that of transmitting the two in different signaling, and the flexibility is higher than that of the two being the same information or having a containing relationship.

[0159] In another embodiment, the eighth indication information and the first indication information / third indication information are transmitted in different signaling; in this way, the signaling design flexibility is better.

[0160] As an example, the RS resources included in the first RS resource group are all CSI-RS resources, and the RS resources included in the second RS resource group are all CSI-RS resources.

[0161] As an example, the RS resources included in the first RS resource group are demodulation reference signals (DMRS), and the RS resources included in the second RS resource group are demodulation reference signals.

[0162] As other examples, the RS resources included in the first RS resource group and the second RS resource group can be other types of RS resources (i.e., non-CSI-RS resources, non-DMRS resources).

[0163] It should be noted that the RS resource group can also be referred to as an RS set (RS group) or an RS resource set.

[0164] It should be noted that the concept of an RS resource group may or may not appear in the actual protocol. The resource group (e.g., the first RS resource group and the second RS resource group) in the embodiments of the present application can be an actual resource group appearing in the protocol, or a concept of logically dividing different RS resources, which does not actually appear in the protocol (for example, there are two RS resources, and the specific configuration / purpose is different, so the first RS resource can be included in one RS group, and the second RS resource can be included in another RS group).

[0165] By way of example, the first RS resource group includes N1 RS resources (N1 is 1 or an integer greater than 1); the second RS resource group includes N2 RS resources (N2 is 1 or an integer greater than 1). In an embodiment, N1 = 1; in an embodiment, N2 = 1; in an embodiment, N1 = N2 = 1. It can be understood that N1 and N2 can also have other values.

[0166] In some embodiments, the first device can determine the first RS resource and the second RS resource are associated, so as to facilitate the first device to collect data and explicitly indicate the relationship between the collected data. The following exemplary describes the indication of the association between the first RS resource and the second RS resource.

[0167] The indication of the association can have different implementations, including at least one of the following:

[0168] Method 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.

[0169] 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 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.

[0170] Optionally, the first indication information can indicate the configuration information of the first RS resource, or the first indication information can include the configuration information of the first RS resource.

[0171] Optionally, the first indication information or the third indication information can indicate the configuration information of the second RS resource, or the first indication information or the third indication information can include the configuration information of the second RS resource.

[0172] For example, if the first field in the configuration information of the first RS resource has a value Y, and the second field in the configuration information of the second RS resource has the same function as the first field and has the value Y, the first RS resource and the second RS resource have an association relationship.

[0173] Compared with indicating the association relationship between the RS resource groups, this method indicates the association relationship between the RS resources, which can increase flexibility, and the second device can indicate various pairing relationships in more fine-grained.

[0174] Method 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 second RS resource, it means that the first RS resource and the second RS resource have an association relationship.

[0175] Compared with indicating the association relationship between the RS resource groups, this method indicates the association relationship between the RS resources, which can increase flexibility, and the second device can indicate various pairing relationships in more fine-grained.

[0176] 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.

[0177] 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.

[0178] Manner 4: The above resource configuration method further includes that the second device sends fourth indication information. Correspondingly, the first device receives the fourth indication information. The fourth indication information is used by the first device to determine that the first RS resource is associated with the second RS resource.

[0179] That is, the second device indicates through the fourth indication information that the first RS resource and the second RS resource have an association relationship. 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.

[0180] Optionally, the fourth indication information is included in the first indication information.

[0181] Optionally, the fourth indication information and the first indication information are the same signaling. For example, the first RS resource and the second RS resource appear in pairs in the resource configuration signaling (for example, appear in pairs in one RS resource configuration signaling). For another example, the first RS resource and the second RS resource are indicated in the same measurement configuration signaling or the same reporting configuration signaling.

[0182] Optionally, the fourth indication information and the first indication information are different signaling.

[0183] Manner 5: The first indication information is used to indicate the second RS resource and indicate that part of the resources in the second RS resource is the first RS resource.

[0184] Specifically, the second device indicates the second RS resource through the first indication information, and indicates that part of the resource groups in the second RS resource form 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 the resource groups or directly indicating the association relationship between the resources, this manner can reduce signaling overhead.

[0185] For example, the second RS resource has K2 ports, and K1 (K1 < K2) ports of 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), and the ports (0, 4, 8, 12) in the second RS resource form the first RS resource.

[0186] Manner 6: The fifth field in the configuration information of the first RS resource group to which the first RS resource belongs has the same value as the sixth field in the configuration information of the second RS resource group to which the second RS resource belongs.

[0187] 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 of 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.

[0188] Optionally, the seventh 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 seventh indication information can include the configuration information of the first RS resource group.

[0189] Optionally, the seventh indication information or the eighth indication information used to indicate the second RS resource group in the foregoing embodiments can indicate the configuration information of the second RS resource group, or the seventh indication information or the eighth indication information can include the configuration information of the second RS resource group.

[0190] For example, if the fifth field in the configuration information of the first RS resource group has a value Z, and the sixth field in the configuration information of the second RS resource group has the same function as the first field and has the value Z, the first RS resource group has an association relationship with the second RS resource group.

[0191] Compared with indicating the association relationship between RS resources, this manner indicates the association relationship between RS resource groups, which can reduce the overhead.

[0192] Manner 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 indicates that the first RS resource group has an association relationship with the second RS resource group.

[0193] Compared with indicating the association relationship between RS resources, this manner indicates the association relationship between RS resource groups, which can reduce the overhead.

[0194] Manner 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 indicates that the first RS resource group has an association relationship with the second RS resource group.

[0195] Compared with indicating the association relationship between RS resources, the method indicates the association relationship between RS resource groups, which can reduce the overhead.

[0196] Method 9: The resource configuration method further includes that the second device sends fifth indication information. Correspondingly, the first device receives the fifth indication information; wherein the fifth indication information is used by the first device to determine that the first RS resource group is associated with the second RS resource group.

[0197] That is, the second device indicates through the fifth indication information that the first RS resource group and the second RS resource group have an association relationship. Compared with indicating the association relationship between RS resources, the method indicates the association relationship between RS resource groups, which can reduce the signaling overhead.

[0198] Optionally, the fifth indication information is contained in the seventh indication information used to indicate the first RS resource group (optionally, also indicating the second RS resource group).

[0199] Optionally, the fifth indication information and the seventh indication information are the same signaling. For example, the first RS resource group and the second RS resource group appear in pairs in the resource configuration signaling (for example, appearing in pairs in one RS resource configuration signaling). For another example, the first RS resource group and the second RS resource group are indicated in the same measurement configuration signaling or the same reporting configuration signaling.

[0200] Optionally, the fifth indication information and the seventh indication information are different signaling.

[0201] In some embodiments, when it is indicated that the first RS resource group is associated with the second RS resource group, the RS resources in the first RS resource group and the corresponding RS resources in the second RS resource group all have an association relationship. In this way, the signaling overhead can be reduced.

[0202] In some embodiments, the above different methods can be combined for use, for example, one of methods 1-5 can be combined with one of methods 6-9. For another example, methods 2 and 3 can be combined, and for another example, methods 7 and 8 can be combined. These combination schemes can achieve a better trade-off between signaling overhead and flexibility.

[0203] Assume that the first RS resource group contains N1 RS resources (N1 is 1 or an integer greater than 1), and the second RS resource group contains N2 RS resources (N2 is 1 or an integer greater than 1). For the case of N1 = N2 = 1 (i.e., the first RS resource group contains only the first RS resource, and the second RS resource group contains only the second RS resource), any one or more of the above manners 1-5 can be used to indicate that the first RS resource and the second RS resource have an association relationship; or any one or more of the above manners 6-9 can be used to indicate that the first RS resource group and the second RS resource group have an association relationship, and when the first RS resource group and the second RS resource group have an association relationship, the first RS resource in the first RS resource group and the second RS resource in the second RS resource group have an association relationship.

[0204] For the case of N1 > 1 and / or N2 > 1, the above scheme can be simply extended by a few examples (more cases can be similarly obtained, and are not listed one by one).

[0205] Take N1 = 1, N2 = 2 as an example. The RS resource in the first RS resource group is denoted as RS X1, and the two RS resources in the second RS resource group are denoted as RS Y1 and RS Y2 respectively.

[0206] One implementation example: the second device indicates by signaling that the first RS resource group and the second RS resource group have an association relationship (for example, by one or a combination of multiple ones of the above manners 6-9), and then the RS resource in the first RS resource group and each RS resource in the second RS resource group have an association relationship, i.e., RS X1 and RS Y1 have an association relationship, and RS X1 and RS Y2 have an association relationship. This manner can reduce signaling overhead.

[0207] Another implementation example: the second device indicates by signaling that the first RS resource group and the second RS resource group have an association relationship (for example, by one or a combination of multiple ones of the above manners 6-9), and the second device also indicates that RS X1 and RS Y1 have an association relationship (for example, by one or a combination of multiple ones of the above manners 1-5). The signaling indication of this manner is more flexible, and can indicate the association relationship in a finer granularity.

[0208] Another implementation example is that the second device indicates by signaling that RS X1 and RS Y1 have an association relationship (for example, by one or a combination of multiple ones of the above manners 1-5). The indication of this manner is more flexible.

[0209] Take N1=2, N2=2 as an example. The two RS resources in the first RS resource group are denoted as RS X1 and RS X2, and the two RS resources in the second RS resource group are denoted as RS Y1 and RS Y2.

[0210] An implementation example: the second device indicates by signaling that the first RS resource group and the second RS resource group have an association relationship (for example, indicated by one of the above modes 6-9 or a combination of multiple modes). In this way, each RS resource in the first RS resource group has an association relationship with each RS resource in the second RS resource group. This mode can reduce signaling overhead.

[0211] For example, RS X1 and RS X2 are the first and second RS resources in the first RS resource group, respectively (determined according to the position in the first resource group). RS Y1 and RS X2 are the first and second RS resources in the second RS resource group, respectively (determined according to the position in the second resource group). RS X1 has an association relationship with RS Y1, and RS X2 has an association relationship with RS Y2.

[0212] For another example, RS X1 and RS X2 are the RS resources with the larger and smaller corresponding numbers in the first RS resource group, respectively, that is, the number corresponding to RS X1 is larger than the number corresponding to RS X2, which can be an RS resource index / indicator. RS Y1 and RS Y2 are the RS resources with the larger and smaller corresponding numbers in the second RS resource group, respectively, that is, the number corresponding to RS Y1 is larger than the number corresponding to RS Y2, which can be an RS resource index / indicator. RS X1 has an association relationship with RS Y1, and RS X2 has an association relationship with RS Y2.

[0213] Another implementation example: the second device indicates by signaling that the first RS resource group and the second RS resource group have an association relationship (for example, indicated by one of the above modes 6-9 or a combination of multiple modes), and the first network also indicates that RS X1 has an association relationship with RS Y1 (for example, indicated by one of the above modes 1-5 or a combination of multiple modes). In this way, the signaling overhead can be reduced.

[0214] Another implementation example: the second device indicates through signaling that the first RS resource group and the second RS resource group have an association relationship (for example, indicated by one of the above modes 6-9 or a combination of multiple modes), and the first network also indicates that RS X1 and RS Y1 have an association relationship and RS X2 and RS Y2 have an association relationship (for example, indicated by one of the above modes 1-5 or a combination of multiple modes). This mode has better signaling flexibility and can indicate the association relationship in finer granularity.

[0215] Another implementation example is that the second device indicates through signaling that RS X1 and RS Y1 have an association relationship and RS X2 and RS Y2 have an association relationship (for example, indicated by one of the above modes 1-5 or a combination of multiple modes). This mode has better signaling flexibility.

[0216] In some embodiments, the first device performs channel measurement based on the first RS resource, and can report a first reporting result based on the first RS resource to the network (which can be a server or a second device, and the second device can include the first network device); the first device performs channel measurement based on the second RS resource, and can report a second reporting result based on the second RS resource to the network.

[0217] For the result reporting of the first device, in some embodiments, the first indication information and / or the third indication information are further used to indicate one or more of the following information: reporting content related information, reporting format related information, and quantization related information of the reporting result.

[0218] Optionally, the first indication information further indicates one or more of the following information:

[0219] Reporting content related information; for example, indicating reporting a channel matrix, or reporting a PMI, or reporting a channel eigenvector, etc.

[0220] Reporting format related information;

[0221] Quantization related information of the reporting result.

[0222] Optionally, the first indication information can indicate one or more of the reporting content related information, the reporting format related information, and the quantization related information of the reporting result associated with the first RS resource. Optionally, the first indication information can also indicate one or more of the reporting content related information, the reporting format related information, and the quantization related information of the reporting result associated with the second RS resource.

[0223] Optionally, the third indication information further indicates one or more of the following information:

[0224] reporting content related information; for example, indicating reporting a channel matrix, or reporting a PMI, or reporting a channel eigenvector, etc.

[0225] reporting format related information;

[0226] quantization related information of the reporting result.

[0227] Optionally, the first indication information can also indicate one or more of the reporting content related information, the reporting format related information, and the quantization related information of the reporting result associated with the second RS resource.

[0228] In some embodiments, the resource configuration method further includes that the first device sends a first reporting signaling. Correspondingly, the second device receives the first reporting signaling. Wherein, the first reporting signaling includes the first information obtained based on the first RS resource and / or the second RS resource.

[0229] For example, the first device reports the first information obtained based on the first RS resource and the second RS resource in the first reporting signaling. That is, the first device reports the result corresponding to the first RS resource and the result corresponding to the second RS resource through one reporting signaling.

[0230] In some embodiments, the first reporting signaling also reports the content of the second indication information corresponding to the first information. For example, the first device determines the first RS resource according to the first indication information, and at the same time, also receives the corresponding second indication information (the content of which is denoted as Info1). Then, the first device can include both the first information obtained based on the first RS resource and / or the second RS resource, and the content Info1 of the received second indication information in the first reporting signaling.

[0231] In some embodiments, the first information includes N first reporting results obtained based on the first RS resource and M second reporting results obtained based on the second RS resource, wherein N and M are both positive integers.

[0232] Optionally, N can be equal to M, or N can be greater than M, or N can be less than M. As an example of an application, if the reporting result included in the first reporting signaling is used for AI model training, then the first reporting result and the second reporting result correspond to the input and output of the AI model respectively.

[0233] In some embodiments, the first reporting signaling does not indicate the correspondence between the first reporting result and the second reporting result. In this case, the correspondence between the first reporting result and the second reporting result is determined through an additional operation. The pairing of the first reporting result and the second reporting result needs an additional operation in order to train the AI model.

[0234] In some embodiments, the first reporting signaling further indicates a correspondence between the first reporting result and the second reporting result. Specifically, the first device includes N first reporting results and M second reporting results in one first reporting signaling, and the first reporting signaling further indicates the correspondence between the first reporting result and the second reporting result. As an implementation case, N can be equal to M. In other implementation cases, N can be greater than M.

[0235] In some embodiments, the first reporting signaling indicates one or more first reporting samples, and each first reporting sample includes one first reporting result and one second reporting result (i.e., one first reporting result and one second reporting result are reported in pairs). Directly embodying the correspondence between the first reporting result and the second reporting result in the reporting information can reduce subsequent data operations, such as not needing additional work to pair data. As an example of an application, if a certain first reporting sample is used for AI model training in the future, the first reporting result and the second reporting result included in the first reporting sample correspond to the input and output of the AI model, respectively.

[0236] In some embodiments, the first information in the first reporting signaling includes N first reporting results obtained based on the first RS resource; and the resource configuration method further includes: the first device sending second reporting signaling. Correspondingly, the second device receives the second reporting signaling. The second reporting signaling includes M second reporting results obtained based on the second RS resource, and N and M are positive integers.

[0237] In some embodiments, the second reporting signaling further reports the content of the second indication information corresponding to the second reporting result. For example, the first device determines the second RS resource according to the first indication information or the third indication information, and also receives the corresponding second indication information (the content of which is denoted as Info2), and the first device can include the second reporting result obtained based on the second RS resource and the content Info2 of the received second indication information in the second reporting signaling.

[0238] That is, the first device includes N first reporting results in one first reporting signaling, and the first device includes M second reporting results in one second reporting signaling. As an implementation case, N can be equal to M. In other implementation cases, N can be greater than M. As an example of an application, if the reporting results included in the first reporting signaling and the second reporting signaling are used for AI model training, the first reporting result and the second reporting result correspond to the input and output of the AI model, respectively. In order to train the AI model, additional operations are needed to pair the first reporting result and the second reporting result.

[0239] The first reporting result and the second reporting result are reported in different signaling, and the pairing of the first reporting result and the second reporting result is not limited in the reporting signaling, which can simplify the signaling design. At the same time, it is also convenient to more flexibly pair the first reporting result and the second reporting result when training the AI model, and provides greater flexibility for training data enhancement.

[0240] In some embodiments, the first reporting signaling and / or the second reporting signaling further comprises one or more of the following:

[0241] Timestamp information, cell-related information, PLMN information, location information, speed-related information, reliability-related information, error-related information, wireless environment-related information, and content of the second indication information corresponding to the reporting result.

[0242] Exemplarily, the first reporting signaling carries corresponding information of one or more of the following types for the first reporting result (and optionally also for the second reporting result):

[0243] (1) Timestamp information (information related to timestamp). The advantage is to facilitate the judgment of the timeliness of the data, and also facilitate the pairing of the first reporting result and the second reporting result.

[0244] For example, the timestamp information can be represented by a value calculated in time units (such as milliseconds, microseconds, …);

[0245] For example, the timestamp information can be represented by an SFN value, a slot number, or a symbol number.

[0246] (2) Cell-related information (information related to cell). The advantage is to facilitate better training data classification when training the AI model. For example, the cell-related identifier can be a global cell identifier (Global cell ID).

[0247] (3) PLMN information. The advantage is to facilitate better training data classification when training the AI model. For example, the PLMN information can be a PLMN ID.

[0248] (4) Location information. The advantage is to facilitate better training data classification when training the AI model.

[0249] (5) Speed-related information. The advantage is to facilitate better training data classification when training the AI model. For example, the speed-related information includes the speed of the first device at the time corresponding to the reporting sample.

[0250] (6) Information related to reliability of the reported result. The benefit is to facilitate better selection of training data when training the AI model. For example, confidence of the reported result.

[0251] (7) Information related to estimation error of the reported result. The benefit is to facilitate better selection of training data when training the AI model. For example, variance information of the reported result.

[0252] (8) Information related to wireless environment. The benefit is to facilitate better classification of training data when training the AI model. For example, characteristics of the current channel, and / or type of the current channel, and / or Signal to Interference plus Noise Ratio (SINR), and / or Reference Signal Received Power (RSRP).

[0253] (9) Content of the second indication information corresponding to the reported result. The benefit is to facilitate better classification of data when training the AI model, for example, different second indication information corresponds to different model for training. Meanwhile, it can also know the applicable condition of the trained AI model.

[0254] Exemplarily, for the second reported result, the second reporting signaling can also carry the following one or more types of information corresponding to the second reported result:

[0255] (1) Information related to timestamp. The benefit is to facilitate the judgment of the timeliness of the data, and also to facilitate the pairing of the first reported result and the second reported result.

[0256] For example, the timestamp information can be represented by a value calculated in time units (e.g., milliseconds, microseconds, …).

[0257] For example, the timestamp information can be represented by SFN value, slot number, symbol number.

[0258] (2) Information related to cell. The benefit is to facilitate better classification of training data when training the AI model. For example, the cell-related identifier can be a global cell ID.

[0259] (3) PLMN information. The benefit is to facilitate better classification of training data when training the AI model. For example, the PLMN information can be a PLMN ID.

[0260] (4) Location information. The benefit is to facilitate better training data classification when training the AI model.

[0261] (5) Speed related information. The benefit is to facilitate better training data classification when training the AI model. For example, the speed related information includes the speed of the first device at the time when the sample is reported.

[0262] (6) Reliability related information of the reported result. The benefit is to facilitate better training data selection when training the AI model. For example, the reliability related information can include the confidence of the reported result.

[0263] (7) Estimation error related information of the reported result. The benefit is to facilitate better training data selection when training the AI model. For example, the estimation error related information can include the variance information of the reported result.

[0264] (8) Wireless environment related information. The benefit is to facilitate better training data classification when training the AI model. For example, the wireless environment related information can include the characteristics of the current channel, and / or the type of the current channel, and / or SINR, and / or RSRP.

[0265] (9) The content of the second indication information corresponding to the reported result. The benefit is to facilitate better data classification when training the AI model, for example, different second indication information corresponds to the reported result for training different models. At the same time, it can also know the applicable conditions of the trained AI model.

[0266] The following describes the first reported result as an example. There are different implementation options for the association relationship between each type of information and the first reported result (assuming that a type of information is denoted as A type information, and the different options are described below by taking the A type information as an example).

[0267] Option 1: one A type information corresponds to one first reported result. That is, in the first reporting signaling, there is one corresponding A type information for each first reported result. For example, in the first reporting signaling, each first reported result has a corresponding time stamp information. For another example, in the first reporting signaling, each first reported result has a corresponding wireless channel environment related information (such as SINR or RSRP). The A type information can also be estimation error related information, reliability related information, speed related information, location information, PLMN information, and cell related information.

[0268] Option 2: one A-type information corresponds to multiple first reporting results. That is, in the first reporting signaling, there is one A-type information corresponding to multiple first reporting results. For example, in the first reporting signaling, multiple first reporting results correspond to one cell-related information. The A-type information can be cell-related information, PLMN information, channel environment-related information, etc.

[0269] As an implementation method, in the first reporting information, for one A-type information, a field or a group of fields is formed, and the field or the group of fields indicates all first reporting results of the A-type information.

[0270] As another implementation, in the first reporting information, for one A-type information, an IE is formed, and the IE includes the A-type information and all first reporting results corresponding to the A-type information.

[0271] The above scheme is also applicable to the second reporting result, and those skilled in the art can directly extend it, so it will not be described again.

[0272] In some embodiments, the resource configuration method further includes: the first device sends a first request message. Correspondingly, the second device receives the first request message. Wherein, the first request message is used to indicate the RS resource required by the first device, or the first request message is used to indicate the RS resource suggested by the first device, or the first request message is used to indicate the RS resource supported by the first device.

[0273] By sending the first request message from the first device to the second device, the second device can send a signal that matches the UE demand for data collection.

[0274] Optionally, the first request message is transmitted through RRC signaling or through MAC CE signaling.

[0275] In some embodiments, the first request information is used to indicate one or more of the following information:

[0276] The maximum number of ports of the first RS resource;

[0277] The cycle-related information of the first RS resource (for example, which cycles can be supported, or which cycles can be supported under certain conditions, or which cycles cannot be supported under certain conditions);

[0278] The maximum number of ports of the second RS resource;

[0279] The cycle-related information of the second RS resource (for example, which cycles can be supported, or which cycles can be supported under certain conditions, or which cycles cannot be supported under certain conditions);

[0280] a correspondence between the first RS resource and the second RS resource (e.g., a pair of the first RS resource and the second RS resource capable of supporting measurement of what condition);

[0281] measurement window related information (or measurement time length related information);

[0282] measurement sample number related information;

[0283] a frequency point or a cell capable of measurement.

[0284] It should be noted that the first RS resource and the second RS resource indicated by the first request information refer to a pair of RS resources required by, or suggested by, or supported by the first device, and the first RS resource and the second RS resource respectively correspond to RS resources with relatively more resource quantity and RS resources with relatively less resource quantity. In actual application, the first RS resource and the second RS resource indicated by the first request information can be the same as or different from the first RS resource and the second RS resource actually indicated by the second device.

[0285] For example, the first device sends the first request message, and the second device needs to perform resource configuration according to the first request information, so the first RS resource and the second RS resource indicated by the first request information are the same as the first RS resource and the second RS resource actually indicated by the second device. For another example, the first device sends the first request message, and the second device can refer to the first request message, but does not need to perform resource configuration according to the first request information, that is, the second device can consider the related information, but does not necessarily have to follow the suggestion in the first request message of the first device, so the first RS resource and the second RS resource indicated by the first request information can be the same as or different from the first RS resource and the second RS resource actually indicated by the second device.

[0286] The indication of the pair of the first RS resource and the second RS resource in the first request message can have different options. In some embodiments, the correspondence between the first RS resource and the second RS resource is indicated by one of the following information:

[0287] (1) a first combination; wherein the first combination is one of a plurality of combinations, and each combination of the plurality of combinations indicates at least one configuration of the first RS resource and at least one configuration of the second RS.

[0288] Optionally, one or more first combinations can be indicated in the first request message.

[0289] Exemplarily, some configurations corresponding to the first RS resource are predefined (e.g., there are N configurations X), some configurations corresponding to the second RS resource are predefined (e.g., there are M configurations Y), and one or more combinations (denoted as first combinations) are indicated in the first request message, where each combination indicates one x and one y, where x is a certain configuration in the N configurations X, and y is a certain configuration in the M configurations Y. An exemplary implementation is that the number corresponding to x (e.g., a value from 1 to N) and the number corresponding to y (e.g., a value from 1 to M) are indicated in each combination. This way has low signaling overhead and also has certain flexibility.

[0290] Optionally, the above predefinition can be network pre-configuration, can be protocol agreement, or can be agreement between manufacturers (e.g., agreement between network equipment manufacturers and terminal equipment manufacturers, or agreement between operators and terminal equipment manufacturers).

[0291] (2) a first configuration; where the first configuration is one of a plurality of predefined or indicated configurations, and each configuration in the plurality of configurations includes configuration information of the first RS resource and configuration information of the second RS resource.

[0292] Optionally, one or more first configurations can be indicated in the first request message.

[0293] Exemplarily, Q configurations Z are predefined, where each configuration indicates one configuration corresponding to the first RS resource and one configuration corresponding to the second RS resource. One or more of the Q configurations Z (denoted as first configurations z) corresponding to one or more configuration combinations of the first RS resource and the second RS resource are indicated in the first request message. An exemplary implementation is that each combination is indicated by indicating the number corresponding to z (e.g., a value from 1 to Q). This way has small signaling overhead.

[0294] Optionally, the above predefinition can be network pre-configuration, can be protocol agreement, or can be agreement between manufacturers (e.g., agreement between network equipment manufacturers and terminal equipment manufacturers, or agreement between operators and terminal equipment manufacturers).

[0295] (3) configuration of the first RS resource and configuration of the second RS resource.

[0296] Exemplarily, one or more information is indicated in the first request message, where each information indicates one configuration corresponding to the first RS resource and one configuration corresponding to the second RS resource. Where the configuration information can be one or more of the following: pattern of the RS, maximum port number of the RS resource, RS period, and the like. This way has better flexibility.

[0297] In some embodiments, the resource configuration method further comprises: the first device sending first capability information. Correspondingly, the second device receives the first capability information. The first capability information indicates the measurement capability of the first device for the first RS resource and / or the second RS resource.

[0298] In some embodiments, the first capability information is carried by UE capability signaling or terminal assistance information.

[0299] By reporting the UE capability through the UE capability signaling, the UE capability can be reported without repetition in different cells.

[0300] Optionally, the first capability information is transmitted through RRC signaling or MAC CE.

[0301] In some embodiments, the first capability information is reported for one of the following: a frequency band, a frequency band combination, each frequency band in the frequency band combination, each carrier of each frequency band in the frequency band combination, a frequency band range, and the first device.

[0302] Specifically, the following optional modes can be used:

[0303] Optionally, the first capability information is reported per band (i.e., the corresponding capability can be independently reported for different frequency bands).

[0304] Independent reporting of different frequency bands can give the first device greater freedom in implementation, for example, the first device can support this function on a certain band or bands and not support this function on other bands, thereby allowing more terminal devices to support this new function. Optionally, the first capability information is independently reported per band combination (per band combination).

[0305] Independent reporting of different frequency band combinations can give the first device greater freedom in implementation, for example, the first device can not support this function under a certain frequency band combination but support this function under another frequency band combination, thereby allowing more terminal devices to support this new function.

[0306] Optionally, the first capability information is reported per band per band combination (i.e., the bands in different band combinations can be reported independently). Reporting independently per band combination can allow the first device to have greater freedom, for example, the first device can not support this function under a certain CA, but some bands support this function under another CA combination, so that more terminal devices can support this new function.

[0307] Optionally, the first capability information is reported per CC per band per band combination (i.e., different CCs in bands in different band combinations can be reported independently, per CC per band per band combination, or FSPC). Reporting independently per band combination and different CCs in a band can allow the first device to have greater freedom, so that more terminal devices can support this new function.

[0308] Optionally, the first capability information is reported per FR (i.e., different FRs can be reported independently, per FR, i.e., FR1 and FR2 are reported independently). Reporting independently per FR can allow the first device to have greater freedom, 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.

[0309] Optionally, the first capability information is reported for the first device, or for the UE (i.e., per UE, if the UE reports this capability, it can support this capability on all bands). This approach can reduce the signaling overhead of terminal capability reporting.

[0310] In some embodiments, the resource configuration method further includes: the first device sending second capability information. Correspondingly, the second device receives the second capability information. The second capability information indicates the measurement capability of the first device for the first RS resource and / or the second RS resource.

[0311] In some embodiments, the second capability information is carried by UE assistance information. Carrying the second capability information by the UE assistance information has better flexibility, and the first device can indicate its own capability according to the current situation (e.g., computing resources, power consumption, power).

[0312] Optionally, the second capability information is transmitted through RRC signaling or MAC CE.

[0313] In some embodiments, the second capability information is reported for a serving cell.

[0314] Optionally, when the first device reports the second capability information, the second capability information is applicable to the serving cell currently transmitting the second capability information or all serving cells of the first device.

[0315] Optionally, when the first device reports the second capability information, the second capability information is applicable to the serving cell indicated by the serving cell indication information.

[0316] 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 and the second RS resource.

[0317] To facilitate understanding of the technical solutions of the embodiments of the present application, two specific application examples are provided below.

[0318] Application Example One:

[0319] This application example is mainly used for UE-side AI model training, so the network needs to indicate that the first RS resource and the second RS resource correspond to each other. In fact, it can also be used for network-side AI model training.

[0320] FIG. 4 shows an interaction flowchart of this application example. As shown in FIG. 4, in this application example, the resource configuration method includes:

[0321] S410, the first terminal device receives first indication information sent by the first network device.

[0322] S420, the first terminal device determines a first RS resource group and a second RS resource group according to the first indication information.

[0323] The first RS resource group includes the first RS resource, and the second RS resource group includes the second RS resource.

[0324] The first RS resource group and the second RS resource group are respectively used for channel measurement. Taking the first resource group as an example, for example, the first terminal device can obtain CSI based on the first resource group measurement. For another example, the first terminal device can demodulate data and / or control information based on the RS measurement in the first RS resource group.

[0325] Optionally, in the application example, the resource configuration method further includes:

[0326] The first network device further sends second indication information to the first terminal device. The second indication information indicates that the training data and the AI model actually use corresponding related network conditions / configurations to maintain consistency.

[0327] In the application example, the first RS resource group and the second RS resource group have an association relationship with the RS resources therein. The indication of the association relationship can be implemented by referring to the description of the foregoing embodiments, which will not be described here. The difference between the first RS resource and the second RS resource can also be implemented by referring to the description of the foregoing embodiments, which will not be described here.

[0328] In the application example, the reporting of the collected data by the first terminal device is an optional step, and in actual application, it can not be necessary to report to the network. The reporting process can include: the first terminal device performs channel measurement according to the first RS resource, and reports the first reporting result to the network (which can be a server or the first network device); the first terminal device performs channel measurement according to the second RS resource, and reports the second reporting result to the network (which can be a server or the first network device).

[0329] Optionally, before the above steps, the first terminal device sends a first request message to the first network device.

[0330] Optionally, before the above steps, the first terminal device reports a first terminal capability (which can also be referred to as first capability information) to the first network device, and the first terminal capability is the measurement capability of the first RS resource and the second RS resource.

[0331] Optionally, before the above steps, the first terminal device reports a second terminal capability (which can also be referred to as second capability information) to the first network device, and the second terminal capability is the measurement capability of the first RS resource and the second RS resource.

[0332] In the application example, the implementation of one or more of the first request message, the first capability information, and the second capability information can refer to the description of the foregoing embodiments, which will not be described here.

[0333] Application Example Two:

[0334] The application example is mainly used for network side AI model training, and therefore the network does not indicate that the first RS resource and the second RS resource are corresponding. It can be understood that in actual application, it can also be used for UE side AI model training, for example, after the network collects data, the data is paired first, and then the paired data is provided to the UE.

[0335] FIG. 5 shows an interaction flowchart of the application example. As shown in FIG. 5, in the application example, the resource configuration method includes:

[0336] S510, the first terminal device receives first indication information sent by the first network device;

[0337] S520, the first terminal device determines a first RS resource group according to the first indication information;

[0338] S530, the first terminal device receives third indication information sent by the first network device;

[0339] S540, the first terminal device determines a second RS resource group according to the third indication information;

[0340] The first RS resource group includes the first RS resource, and the second RS resource group includes the second RS resource.

[0341] It should be noted that the order between the processing steps S510 and S520 of the first indication information and the processing steps of the third indication information is not limited. The transmission of the first indication information and the determination of the first RS resource group can be performed first, and then the transmission of the third indication information and the determination of the second RS resource group can be performed. The transmission of the third indication information and the determination of the second RS resource group can be performed first, and then the transmission of the first indication information and the determination of the first RS resource group can be performed. The transmission of the first indication information and the determination of the first RS resource group can be performed simultaneously.

[0342] In the application example, the UE reports the result based on the RS resource. Optionally, the first indication information further indicates one or more of the following information:

[0343] report content related information;

[0344] report format related information;

[0345] quantization related information of the reported result.

[0347] report content related information;

[0348] report format related information;

[0349] quantization related information of the reported result.

[0350] The first RS resource group and the second RS resource group are respectively used for channel measurement. Taking the first resource group as an example, the first terminal device can obtain CSI based on the channel measurement of the first resource group. For another example, the first terminal device can demodulate data and / or control information based on the RS measurement in the first RS resource group.

[0351] In the application example, the first terminal device reports the collected data. The reporting process can include: the first terminal device performs channel measurement according to the first RS resource, and reports the first reporting result to the network (which can be a server or the first network device); the first terminal device performs channel measurement according to the second RS resource, and reports the second reporting result to the network (which can be a server or the first network device).

[0352] In an implementation process of the application example, the first network device sends the first indication information, the first terminal device performs measurement according to the corresponding configuration information, and reports the first reporting result through the first reporting signaling; the first network device sends the third indication information, the first terminal device performs measurement according to the corresponding configuration information, and reports the second reporting result through the second reporting signaling. After collecting the data, the data owner (for example, the network, or the network device vendor, or the operator) processes (for example, matches) the collected first reporting result and second reporting result, and then uses them for AI model training, for example, the first reporting result and the second reporting result correspond to the input and output of the AI model respectively. From the perspective of the first terminal device, it can not know the correlation between the two measurements / reporting (corresponding to the first indication information and the third indication information respectively).

[0353] Optionally, before the above steps, the first terminal device reports the first terminal capability (which can also be referred to as first capability information) to the first network device, and the first terminal capability is the measurement capability of the RS resource.

[0354] Optionally, before the above steps, the first terminal device reports the second terminal capability (which can also be referred to as second capability information) to the first network device, and the second terminal capability is the measurement capability of the RS resource.

[0355] In the application example, one or more of the first capability information and the second capability information can be implemented by referring to the description of the foregoing embodiments, which will not be described here.
