[0061] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0062] Currently, research and discussion are underway in the communications field on the integration of AI into the physical layer of wireless communication systems. Key use cases for AI in wireless communication systems include AI-enhanced CSI (Channel State Information) compression feedback, AI-enhanced beam management, and AI-enhanced positioning. Looking further ahead, wireless AI is likely to become one of the most important enabling technologies for 6G, and AI models will play a vital role in many aspects of wireless communication systems. However, flexible management and control of the vast number of AI models will be a critical consideration for future wireless systems.

[0063] The current discussion on model management and indication is still in its early stages, with relatively simple considerations regarding the required flexibility and complexity of the scenarios to be addressed. However, in the future, wireless communication systems will need to define a comprehensive LCM (Life Circle Management) mechanism for AI models that will support functions such as model indication, model switching, model performance monitoring, and model transmission. As the foundation of AI model LCM, model indication based on model ID will also be a key focus of discussion.

[0064] Model indication is a key mechanism supporting LCM. Functions such as model selection, model switching, and model activation / deactivation are all based on model indication. As wireless communication systems progress from initial AI implementation to advanced stages, flexible and efficient model indication mechanisms will play an increasingly important role.

[0065] The initial stage of AI adoption: Based on traditional wireless communication systems, AI models are used to replace or enhance key traditional functional modules to improve performance. For example, AI models can replace or enhance functional modules related to CSI compression feedback, beam management, and positioning. During this stage, the impact of AI models is limited to a local area of ​​the system, with relatively simple functions and easy management. However, compared with traditional algorithms, while AI offers performance advantages, its generalization ability to address diverse scenarios is much weaker. Therefore, when faced with different wireless communication environments and system configurations, it is often necessary to select and switch to the most suitable AI model to achieve optimal performance. If the system does not support a flexible model indication mechanism, the model selection and switching process will not be carried out in a timely manner. Inappropriate models will impair system performance and even cause communication interruptions.

[0066] In the mature AI stage, AI models will not only partially replace traditional modules but will be more widely applied across all parts of the system, even reconfiguring entire communication links, thereby achieving an inherently intelligent communication system. A highly promising technology direction is the fully AI-based communication transceiver. Figure 2 shows a schematic diagram of an AI-based communication transceiver. As shown in Figure 2, the transmitter and receiver components of wireless communication are integrated using AI. The overall design can be viewed as an autoencoder (AE) model. The AI-based transmitter acts as an encoder, mapping information bits into a signal suitable for wireless transmission, while the AI-based receiver acts as a decoder, recovering the received signal back into information bits. In this scenario, the AI ​​models on the transmitter and receiver operate as a matching dual-end model. When one model is adjusted or switched, the other model must also be adjusted or switched accordingly. Otherwise, the mismatch between the dual-end models will lead to severe loss of communication performance or even interruption. Compared to the initial stages of AI adoption, the systems at this stage will be filled with numerous AI models that need to match and work together, necessitating more refined control and management of these models. For example, in the initial stages, model switching to adapt to changes in the wireless environment may only require a relatively long timeframe (e.g., seconds, minutes, or hours), while in the mature stage, support for more fine-grained model switching (e.g., milliseconds or time slots) may be required.

[0067] In summary, in order to cope with the development of future wireless communication systems and the diversified needs for AI model management, the system needs to support flexible and efficient model indication functions, which can efficiently support model indication at long or short time granularity.

[0068] Specifically, the network and / or UE can obtain or store one or more AI models through a certain mechanism, and different models have model IDs bound to them (which can be globally unique or locally unique). The network or UE indicates / configures the model ID to the other party through signaling, thereby implementing model indication.

[0069] In a highly intelligent wireless communication system, it is necessary to manage a large number of AI models of various types. With so many models, it is difficult to represent the model identifier (such as the model ID) with a small number of bits. This leads to the following contradictions:

[0070] Indicating the model ID through underlying control signaling ensures flexibility. Because underlying control signaling has a short transmission period, it can support model indication at the millisecond and slot levels. However, given the length of the model ID, underlying control signaling may not have sufficient transmission resources to support it. Examples of underlying control signaling include DCI and UCI.

[0071] Even if the signaling transmission resources required for a very long model ID can be fully met by using higher-layer control signaling, flexibility is difficult to guarantee. This is because higher-layer signaling has a long configuration cycle, making it difficult to support millisecond-level or slot-level model indication. Here, higher-layer control signaling is, for example, RRC signaling.

[0072] The technical solutions of the embodiments of this application are mainly intended to solve the above technical problems.

[0073] FIG3 is a schematic flow chart of an information indication method according to an embodiment of the present application. The method can optionally be applied to the system shown in FIG1 , but is not limited thereto. The method includes:

[0074] S310. The first device sends a first signaling to the second device; wherein the first signaling is used to indicate target model information in a first model information set; and the first model information set is configured based on the second signaling.

[0075] Corresponding to the above method, FIG4 is a schematic flow chart of an information indication method according to another embodiment of the present application. The method can optionally be applied to the system shown in FIG1 , but is not limited thereto. The method includes:

[0076] S410. The second device receives a first signaling from the first device; wherein the first signaling is used to indicate target model information in a first model information set; and the first model information set is configured based on the second signaling.

[0077] In the embodiments of the present application, the first device may be a terminal device or a network device. Correspondingly, the second device may be a network device or a terminal device. Optionally, the first device is a terminal device and the second device is a network device. Alternatively, the first device is a network device and the second device is a terminal device.

[0078] In an embodiment of the present application, the first model information set may include multiple model information. Each piece of model information may correspond to a model, and the model information is used to describe the corresponding model. For example, the model information may include the ID (Identifier) ​​of the model. Here, the model refers to a model used to implement a specific function in a wireless communication system. Optionally, the model may be an AI / ML (Machine Learning) model.

[0079] It should be understood that in the embodiments of the present application, the model information set may also be referred to as a model information candidate set, a model information candidate pool, a model information list, etc.

[0080] Optionally, the target model information may be specific model information among multiple model information, for example, model information corresponding to a model selected by the first device, or model information corresponding to a model activated / deactivated by the first device.

[0081] Optionally, the number of target model information may be one or more.

[0082] In this embodiment of the present application, the first model information set is configured based on the second signaling. In other words, the first device and the second device determine the first model information set by transmitting the second signaling. This means that the second signaling enables both parties to confirm / agree on the first model information set. Alternatively, the second signaling can be sent from the first device to the second device, or from the second device to the first device.

[0083] Optionally, the first signaling may be used to indicate the target model information in the first model information set. In other words, the first signaling is used for the second device to determine the target model information in the first model information set.

[0084] According to an embodiment of the present application, on the basis of configuring the first model information set through the second signaling, the target model information in the first model information set is indicated through the first signaling. In this way, the first signaling can indicate the target model information within a smaller range, does not require excessive transmission resource overhead, and can be sent more frequently, thereby ensuring the flexibility of model indication. Specifically, when it is necessary to implement model indication quickly and at a high frequency, the target model information can be indicated in the first model information set using a small number of bits through the first signaling. When the model candidate range undergoes large-scale changes, it can be updated through the second signaling, thereby taking into account the flexibility of model indication and the large-scale indication requirements of the model.

[0085] The above method can be applied to scenarios such as model selection, switching, activation, and deactivation. For example, if multiple CSI feedback models are configured for a terminal device in the network, the terminal device can switch to using one of the CSI feedback models by indicating one of the CSI feedback models.

[0086] In some embodiments, the transmission period of the first signaling is less than or equal to the transmission period of the second signaling. The transmission period may also be referred to as a configuration period. For example, the transmission period of the first signaling may be in milliseconds or time slots. The transmission period of the second signaling may be several times, tens of times, or the like, longer than the transmission period of the first signaling.

[0087] It should be noted that the transmission period is used to represent the minimum time interval for signaling transmission, but it does not limit the periodic transmission of signaling. For example, the transmission period of the first signaling is 1 millisecond, which means that the first signaling can be sent once every 1 millisecond. That is, the system supports millisecond-level transmission of the first signaling. However, in actual applications, whether to send the first signaling can be determined based on the scenario requirements.

[0088] In some embodiments, the first signaling may be lower layer control signaling, and the second signaling may be higher layer control signaling. Examples of lower layer configuration signaling include DCI (Downlink Control Information) and UCI (Uplink Control Information); examples of higher layer configuration signaling include MAC CE (MAC Control Element) and RRC (MAC Control Element) signaling.

[0089] In some embodiments, the first signaling may be dynamic signaling, and the second signaling may be semi-static signaling.

[0090] Exemplarily, the first signaling includes DCI, UCI or a first MAC CE.

[0091] Exemplarily, the second signaling includes RRC signaling and / or a second MAC CE.

[0092] For example, the second signaling includes RRC signaling, and the first signaling is DCI or UCI. That is, after the first model information set is configured through RRC signaling, the target model information in the first model information set is indicated through DCI or UCI.

[0093] For another example, the second signaling is a MAC CE and the first signaling is a DCI or UCI. That is, after the first model information set is configured through the MAC CE, the target model information in the first model information set is indicated through the DCI or UCI.

[0094] For another example, the second signaling is RRC signaling, and the first signaling is MAC CE. That is, after the first model information set is configured through RRC signaling, the target model information in the first model information set is indicated through MAC CE.

[0095] For another example, the second signaling is a second MAC CE, and the first signaling is a first MAC CE. That is, after configuring the first model information set through the second MAC CE, the target model information in the first model information set is indicated through the first MAC CE.

[0096] For another example, the second signaling includes RRC signaling and MAC CE, and the first signaling is DCI or UCI. That is, after configuring the first model information set through RRC signaling and MAC CE, the target model information in the first model information set is indicated through DCI or UCI.

[0097] For another example, the second signaling includes RRC signaling and a second MAC CE, and the first signaling is a first MAC CE. That is, after configuring the first model information set through the combination of RRC signaling and the second MAC CE, the first MAC CE passed indicates the target model information in the first model information set.

[0098] In some embodiments, the second signaling includes a first model information set; each piece of model information in the first model information set includes an ID of a model corresponding to the model information.

[0099] That is, the second signaling can carry a complete first model information set, including the IDs of multiple models. Figure 5 is a schematic diagram of the first model information set in an embodiment of the present application. As shown in Figure 5, the model information set configured by the second signaling can include the IDs of multiple models.

[0100] Optionally, in combination with the foregoing embodiment, the second signaling includes high-layer control signaling such as RRC and / or MAC CE, which can fully meet the required transmission resources for a large number of model IDs with large information lengths.

[0101] In some embodiments, each piece of model information also includes attribute information of the model corresponding to the model information.

[0102] Optionally, the attribute information includes at least one of the following:

[0103] Information 1. Functional information of the model;

[0104] For example, the function information of the model may be used to indicate or describe the function of the model, including CSI feedback, beam management, positioning, channel estimation, or signal detection.

[0105] Information 2: the frequency domain interval to which the model is applicable;

[0106] Exemplarily, the frequency range to which the model is applicable may refer to a BWP (Bandwidth Part) to which the model is applicable. Optionally, the ID of the BWP to which the model is applicable may be used to indicate the frequency range to which the model is applicable.

[0107] Information 3: The spatial domain interval to which the model is applicable;

[0108] Exemplarily, the spatial domain interval to which the model is applicable may be the beam to which the model is applicable. Optionally, a TCI (Transmission Configuration Indicator) state (TCI state) may be used to indicate the spatial domain interval to which the model is applicable.

[0109] Information 4: Logical channels to which the model applies.

[0110] Exemplarily, the logical channels to which the model applies may include one or more of PDCCH (Physical Downlink Control Channel), PDSCH (Physical Downlink Shared Channel), PBCH (Physical Broadcast Channel), PUCCH (Physical Uplink Control Channel), PUSCH (Physical Uplink Control Channel) and PRACH (Physical Random Access Channel).

[0111] It should be noted that in the embodiments of the present application, the attribute information in the model information may include one or more of the above information, for example, it may include only function information, applicable frequency intervals, applicable spatial domain intervals, or applicable logical channels, or it may include function information and applicable frequency intervals, or it may include function information and applicable logical channels, etc. In actual applications, it can be implemented according to scenario requirements, system conventions, etc., and is not listed here.

[0112] Figure 6 shows another schematic diagram of the first model information set in an embodiment of the present application. As shown in Figure 6, the model information set configured through the second signaling can also include attribute information of each model, which is illustrated by taking the applicable BWP ID and applicable logical channel as an example.

[0113] In some embodiments, the first signaling includes an index of the target model information in the first model information set. Since the amount of model information in the first model information set is limited, indicating the target model information by carrying the index of the target model information in the first model information set in the first signaling can significantly reduce transmission resource overhead compared to carrying the target model information itself (including ID, attribute information, etc.), thereby achieving high-frequency transmission, which is conducive to timely, efficient, and flexible model indication.

[0114] For example, as shown in FIG5 and FIG6, the first model information set includes 8 model information, which can be indicated by indexes 0 to 7, so that the target model information can be indicated using 3 bits.

[0115] In some embodiments, the second signaling includes multiple model information sets corresponding to different attribute information, and the multiple model information sets include the first model information set.

[0116] That is, the second signaling can be used to configure multiple model information sets including the first model information set, and different model information sets have different attribute information, such as different applicable BWPs, different applicable logical channels, etc.

[0117] Exemplarily, the second signaling is used to configure different model information sets for different frequency domain intervals, for example, to configure different model information sets for different BWPs.

[0118] Exemplarily, the second signaling is used to configure different model information sets for different logical channels, for example, to configure different model information sets for PDCCH, PDSCH, PBCH, PUCCH, PUSCH, PRACH, etc.

[0119] Exemplarily, the second signaling is used to configure different model information sets for different model functions, such as configuring different model information sets for CSI feedback, beam management, positioning, channel estimation and signal detection.

[0120] Figure 7 is a schematic diagram of multiple model information sets in an embodiment of the present application. Taking different model information sets configured for different logical channels as an example, the multiple model information sets may include model information set 1 configured for PDCCH, model information set 2 configured for PDSCH, and model information set 3 configured for PUSCH.

[0121] In some embodiments, the first signaling includes multiple fields, the multiple fields correspond one-to-one to multiple model information sets, and the first field corresponding to the first model information set among the multiple fields is used to indicate the target model information.

[0122] Optionally, each of the multiple fields is used to indicate target model information in the model information set corresponding to the field, wherein the correspondence between the field and the model information set may be pre-configured.

[0123] Taking the multiple model information sets shown in Figure 7 as an example, the first signaling may include a first field corresponding to model information set 1, a second field corresponding to model information set 2, and a third field corresponding to model information set 3, where the first field is used to indicate model ID#3 in model information set 1, the second field is used to indicate model ID#4 in model information set 2, and the third field is used to indicate model ID#1 in model information set 3.

[0124] In some embodiments, the first signaling includes multiple fields corresponding to different attribute information, and the target model information corresponds to the attribute information corresponding to a first field among the multiple fields.

[0125] In other words, the attribute information corresponding to the target model information is the attribute information corresponding to one of the multiple fields. Optionally, if the first field corresponding to the target attribute information indicates the target model information, the attribute information of the model corresponding to the target model information is the target attribute information.

[0126] The correspondence between the fields and the attribute information may be pre-configured. Optionally, each of the multiple fields is used to indicate, in the first model information set, the model information corresponding to the attribute information corresponding to the field.

[0127] Exemplarily, when only one model information set (first model information set) is configured in the second signaling, the model information can be indicated for different functions or different frequency domain / spatial domain intervals or different logical channels through multiple fields in the first signaling.

[0128] Taking the first model information set shown in Figure 5 as an example, the second signaling configures the first model information set. The first signaling may include a first field corresponding to the CSI feedback function and a second field corresponding to the beam management function. The first field indicates model ID #1, indicating that model ID #1 is used for CSI feedback. The second field indicates model ID #4, indicating that model ID #4 is used for beam management.

[0129] Alternatively, the first signaling may include a first field corresponding to the PDCCH, a second field corresponding to the PDSCH, and a third field corresponding to the PUSCH. The first field indicates model ID #1, indicating that model ID #1 is used for the PDCCH. The second field indicates model ID #4, indicating that model ID #4 is used for the PDSCH. The third field indicates model ID #4, indicating that model ID #4 is also used for the PUSCH.

[0130] In some embodiments, the first field carries the index of the target model information in the first model information set. In other words, the value of the first field is used to indicate the index of the target model information in the first model information set.

[0131] Optionally, each of the multiple fields may carry an index of specific model information in a corresponding model information set, thereby reducing transmission resource overhead.

[0132] In some embodiments, the second signaling may include first configuration signaling and second configuration signaling; wherein the first configuration signaling is used to configure the second model information set; and the second configuration signaling is used to determine the first model information set in the second model information set.

[0133] That is, the second signaling may include multiple different signalings to implement the configuration of the first model information set through multi-level configuration, which is conducive to further balancing the flexibility of model indication and the large-scale indication requirements of the model.

[0134] In some embodiments, the sending period of the second configuration signaling is less than or equal to the sending period of the first configuration signaling.

[0135] Exemplarily, the second configuration signaling may be RRC signaling, the first configuration signaling may be MAC CE, and the first signaling may be DCI or UCI.

[0136] Figure 8 is a schematic diagram of the overall model information configuration framework in this example. As shown in Figure 8, a second model information set (e.g., model IDs #1 to #N) that can contain multiple model IDs is first configured through RRC signaling. A MAC CE is then used to select / activate several model IDs (e.g., model IDs #1 / 5 / 6 / 9) from the second model information set configured by RRC, thereby selecting / activating the first model information set. DCI / UCI signaling is then used to select the final target model information (e.g., model ID #6) indicated in the MAC CE within the first model information set.

[0137] In the above example, when model switching is required quickly and frequently (e.g., millisecond-level or slot-level), only a small number of bits are needed via DCI / UCI to indicate the model within the candidate model range configured at a higher layer. Only when the model candidate range undergoes large-scale changes is an update required via higher-layer signaling (MAC CE or even RRC). Furthermore, the configuration periodicity for model indication signaling, such as RRC, MAC CE, and DCI / UCI, can be different. Figure 9 exemplifies the configuration periodicity of different signaling.

[0138] In some embodiments, the first model information set includes model information activated in the second model information set. Exemplarily, the first configuration signaling configures the second model information set, and the second configuration signaling is primarily used to activate all or part of the model information in the second model information set. The first signaling may indicate target model information in all or part of the activated model information, thereby further reducing the overhead indicated by the first signaling.

[0139] In some embodiments, the first model information set includes model information configured for the first attribute information in the second model information set. In other words, the second configuration signaling is used to configure the first model information set for the first attribute information in the second model information set.

[0140] Optionally, the second signaling may include multiple second configuration signalings to configure multiple model information sets for multiple attribute information, for example, configuring different model information sets for different frequency domain intervals (for example, different BWPs); or configuring different model information sets for different spatial domain intervals (for example, different downlink or uplink beams); or configuring different model information sets for different logical channels; or configuring different model information sets for different model functions.

[0141] For example, after the second model information set is configured through RRC signaling, the model information set corresponding to the CSI feedback function can be indicated in the second model information set through the third MAC CE; and the model information set corresponding to beam management can be indicated in the second model information set through the fourth MAC CE.

[0142] Optionally, the second configuration signaling may further include an indication of the first attribute information, such as an LCID (Logical Channel Identifier), a BWP ID, a TCI ID, etc. For example, if the second configuration signaling is used to configure a first model information set applicable to a PDCCH, the second configuration signaling may further include indication information for the PDCCH.

[0143] Optionally, in the embodiment of the present application, the first configuration signaling may be sent by the second device to the first device, or may be sent by the first device to the second device. Specifically, before the first device sends the first signaling to the second device, the above method may further include:

[0144] The first device receives second configuration signaling from the second device; or,

[0145] The first device sends second configuration signaling to the second device.

[0146] Accordingly, before the second device receives the first signaling from the first device, the method may further include:

[0147] The second device sends a second configuration signaling to the first device; or,

[0148] The second device receives second configuration signaling from the first device.

[0149] Optionally, in the embodiment of the present application, the second configuration signaling may be sent by the second device to the first device, or may be sent by the first device to the second device. Specifically, before the first device sends the first signaling to the second device, the above method may further include:

[0150] The first device receives a first configuration signaling from the second device; or,

[0151] The first device sends first configuration signaling to the second device.

[0152] Accordingly, before the second device receives the first signaling from the first device, the method may further include:

[0153] The second device sends a first configuration signaling to the first device; or,

[0154] The second device receives first configuration signaling from the first device.

[0155] It can be seen that according to the embodiment of the present application, the first device and the second device can collaboratively and interactively complete the model indication, and the system implementation can have greater freedom.

[0156] In some embodiments, before the second device receives the first signaling from the first device, the above method also includes: the second device sends first information to the first device; wherein the first information includes information related to at least one model in the second device, and / or information related to the ability of the second device to switch models in at least one model; the above at least one model includes a model corresponding to the target model information.

[0157] Accordingly, in some embodiments, before the first device sends the first signaling to the second device, the above method further includes: the first device receiving the first information from the second device.

[0158] Among them, the first information includes information related to at least one model in the second device, that is, before the first device indicates the target model information to the second device, the second device can first report the relevant information of the model it owns, so that the first device can understand the model held by the second device.

[0159] The first information includes information related to the second device's ability to switch models between at least one model. That is, before the first device indicates target model information to the second device, the second device may first report information related to the model switching capability, so that the first device can determine the capability of the second device and reasonably indicate the applicable target model information to the second device. For example, the model switching capability may include the duration required for the second device to switch models.

[0160] Optionally, the first information may be carried by RRC, PUCCH, PUSCH, MAC CE or DCI, etc.

[0161] Optionally, the first device may determine the target model information based on the first information, and then indicate it to the second device.

[0162] To facilitate understanding of the methods in the above embodiments, multiple application examples are provided below, taking the interaction between a base station and a UE as an example, to clearly illustrate optional implementation methods of the methods according to the timing of each step.

[0163] Application Example 1

[0164] In this application example, the first device is a base station, and the second device is a UE, that is, the base station performs model indication on the UE.

[0165] In many cases, the base station needs to send AI model instructions to the UE to help the UE complete model selection and switching to achieve better communication performance. For example, when the model used by the UE is no longer suitable for the current scenario, it needs to be switched; or when the base station and UE are working together using a dual-end model (such as the AI ​​transmitter and AI receiver shown in Figure 2), the base station switches to a different base station model, so the UE must also adjust accordingly.

[0166] S1. Preparation stage of model instruction

[0167] As a prerequisite for model indication, the UE needs to obtain or store one or more AI models. The UE can obtain AI models in the following ways:

[0168] (1) Base station provision: The base station itself retains the trained model and sends and configures it to the UE (for example, through RRC messages, broadcast configuration, PDCCH or PDSCH, etc.).

[0169] (2) Manufacturer pre-defined: UE and base station manufacturers each pre-define the AI ​​model and ID they need to use.

[0170] (3) Obtained through third-party channels or agreements.

[0171] Before making a model indication, the base station must ensure that the model and related information (such as ID, model function, etc.) maintained by the UE are known. This information can be reported by the UE (for example, via RRC, PUCCH, PUSCH, etc.). Figure 10 is a schematic diagram of the UE reporting model-related information.

[0172] Furthermore, the UE requires a certain amount of adjustment time to complete model switching, and the length of this time is related to the UE's capabilities. The base station needs to know this time so that it can calculate how long it will take the UE to complete the switch after issuing the model indication signaling. Therefore, the base station requires the UE to report this information. Figure 11 is a schematic diagram of UE reporting information related to model switching capabilities.

[0173] S2. Configure model information set through RRC signaling

[0174] The base station may configure, through RRC signaling, a UE with no more than N (N is an integer greater than or equal to 1) model IDs constituting a model information set, where a single element in the model information set may be:

[0175] (1) Contains only the model ID (see Figure 5 for an example);

[0176] (2) Contains the model ID and one or more of the following information (see Figure 6 for an example):

[0177] Model function indication (indicating the functional classification of the model, such as CSI feedback, beam management, positioning, channel estimation, signal detection, etc.) or description;

[0178] The frequency domain interval to which the model is applicable (e.g., indicated by the BWP ID);

[0179] The spatial domain interval to which the model is applicable (e.g., to which beam(s) the model is applicable, which can be indicated by the TCI status, for example);

[0180] Logical channels to which the model applies (e.g., PDCCH, PDSCH, PBCH, PUCCH, PUSCH, PRACH, etc.).

[0181] The base station can also configure multiple independent model information sets through RRC. Different sets can correspond to different frequency domain / spatial domain intervals or logical channels, or to different model types or functions (see Figure 7 for an example). For example:

[0182] Configure different model information sets for different BWPs;

[0183] Different model information sets are configured for different downlink or uplink beams;

[0184] Configure different model information sets for different logical channels (such as PDCCH, PDSCH, PBCH, PUCCH, PUSCH, PRACH, etc.);

[0185] Different model information sets are configured for different model functions (such as CSI feedback, beam management, positioning, channel estimation, signal detection, etc.).

[0186] The base station may also configure only a common model information set, which is not bound to restriction factors (attribute information) such as BWP, logical channel, beam, etc. The specification of restriction factors may be accomplished through lower-layer signaling (such as MAC CE or DCI).

[0187] When the model information set configured by RRC includes only one piece of model information, the model indication is completed only through RRC signaling, and no further indication is required through MAC CE and / or DCI signaling.

[0188] S3. Select / activate several model IDs from the model information set through MAC CE signaling

[0189] Based on the model information set configured by RRC, the base station can activate no more than M (M is an integer greater than or equal to 1, and M is less than or equal to N) model IDs therefrom through MAC CE signaling.

[0190] In the case where there are multiple independent model information sets configured through RRC (different sets correspond to different frequency domain / spatial domain intervals or logical channels, model functions, etc.), the base station can select / activate no more than M models from different sets through MAC CE signaling, and the specific number of models activated / selected corresponding to different model information sets may be different.

[0191] For the case where there is only a single, common model information set, the base station can activate / select no more than M models for different frequency / spatial domain intervals or logical channels, or corresponding to different model types or functions through MAC CE signaling, for example:

[0192] Configure different model information sets for different BWPs;

[0193] Different model information sets are configured for different downlink or uplink beams;

[0194] Configure different model information sets for different logical channels (such as PDCCH, PDSCH, PBCH, PUCCH, PUSCH, PRACH, etc.);

[0195] Targeting different model functions (such as CSI feedback, beam management, positioning, channel estimation, signal detection, etc.).

[0196] The functions of different intervals / channels / models are reflected through MAC CE signaling (for example, they are distinguished by LCID, or indication fields such as BWP ID / TCI ID are included in MAC CE).

[0197] When the model activated / selected by MAC CE from the model information set includes only one candidate model, the model indication is completed only through RRC and MAC CE signaling, and no further indication is required through DCI signaling.

[0198] S4. Complete model ID indication through DCI

[0199] The base station can directly activate / select the model in the model information set configured by RRC through DCI (skipping MAC CE signaling, that is, the model ID indication is jointly completed by RRC and DCI), or it can indicate the final model in the model selected by MAC CE (that is, the model ID indication is jointly completed by RRC, MAC CE and DCI).

[0200] In the case where there are multiple model information sets configured through RRC or MAC CE (different sets correspond to different frequency domain / spatial domain intervals or logical channels, model functions, etc.), the base station can use different fields of DCI to indicate the models separately.

[0201] In the case where there is only a single, public model information set, the base station can indicate models for different frequency domain / spatial domain intervals or logical channels, or corresponding to different model types or functions through different fields of the DCI signaling.

[0202] Application Example 2

[0203] In this application example, the first device is a UE, and the second device is a base station, that is, the base station performs model indication on the UE.

[0204] As a counterpart to Application Example 1, the UE can also act as the decision-maker and instruct the base station to complete model selection and switching to achieve better communication performance. For example, if the base station and UE are working together using a dual-end model (e.g., Figure 2), and the UE switches to a different UE-end model, the base station must also adjust accordingly. Alternatively, the UE may determine which model the base station uses for optimal performance and therefore needs to indicate this to the base station.

[0205] S1. Preparation stage of model instruction

[0206] As a prerequisite for model indication, assuming that the base station has acquired or stored one or more AI models, the base station AI model acquisition methods may include the following:

[0207] (1) UE provision: The UE uploads the trained model to the base station (e.g., via RRC message, MAC CE, PUCCH, PUSCH, etc.);

[0208] (2) Manufacturer pre-defined: UE and base station manufacturers each pre-define the AI ​​model and ID they need to use.

[0209] (3) Obtained through third-party channels or agreements.

[0210] Before making a model indication, the UE must ensure that it has some knowledge of the model and related information (such as ID, model function, etc.) held by the base station. This information can be delivered by the base station (for example, via RRC, MAC CE, DCI, etc.). Figure 12 is a schematic diagram of the base station delivering model-related information.

[0211] Furthermore, the base station requires a certain amount of adjustment time to complete model switching, and the length of this time is related to the base station's capabilities. The UE needs to know this time so that it can calculate how long it will take for the base station to complete the switch after issuing the model indication signaling. Therefore, the UE requires the base station to issue this information. Figure 13 illustrates a schematic diagram of the base station issuing information related to model switching capabilities.

[0212] S2. Configure model information set through RRC signaling

[0213] The UE may configure the base station through RRC signaling with no more than N (N is an integer greater than or equal to 1) model IDs to form a model information set, where a single element in the set may be:

[0214] (1) Contains only the model ID (see Figure 5 for an example);

[0215] (2) Contains the model ID and one or more of the following information (see Figure 6 for an example):

[0216] Model function indication (indicating the functional classification of the model, such as CSI feedback, beam management, positioning, channel estimation, signal detection, etc.) or description;

[0217] The frequency domain interval to which the model is applicable (e.g., indicated by the BWP ID);

[0218] The spatial domain interval to which the model is applicable (e.g., to which beam(s) the model is applicable, which can be indicated by the TCI status, for example);

[0219] Logical channels to which the model applies (e.g., PDCCH, PDSCH, PBCH, PUCCH, PUSCH, PRACH, etc.).

[0220] The UE may also configure multiple independent model information sets through RRC. Different sets may correspond to different frequency domain / spatial domain intervals or logical channels, or may correspond to different model types or functions. For example:

[0221] Configure different model information sets for different BWPs;

[0222] Different model information sets are configured for different downlink or uplink beams;

[0223] Configure different model information sets for different logical channels (such as PDCCH, PDSCH, PBCH, PUCCH, PUSCH, PRACH, etc.);

[0224] Different model information sets are configured for different model functions (such as CSI feedback, beam management, positioning, channel estimation, signal detection, etc.).

[0225] The UE may also configure only a common model information set, which is not bound to restriction factors such as BWP, logical channel, beam, etc. The specification of restriction factors may be completed through lower-layer signaling (such as MAC CE or UCI).

[0226] When the model information set configured by RRC includes only one candidate model, the model indication is completed only through RRC signaling, and no further indication is required through MAC CE and / or UCI signaling.

[0227] S3. Select / activate several model IDs from the model information set through MAC CE signaling

[0228] Based on the model information set configured by RRC, the UE can activate no more than M (M is an integer greater than or equal to 1, and M is less than or equal to N) model IDs therefrom through MAC CE signaling.

[0229] In the case where there are multiple independent model information sets configured through RRC (different sets correspond to different frequency domain / spatial domain intervals or logical channels, model functions, etc.), the UE can select / activate no more than M models from different sets through MAC CE signaling, and the specific number of models activated / selected corresponding to different model information sets may be different.

[0230] For the case where there is only a single, common model information set, the UE can activate / select no more than M models for different frequency / spatial domain intervals or logical channels, or corresponding to different model types or functions through MAC CE signaling, for example:

[0231] Configure different model information sets for different BWPs;

[0232] Different model information sets are configured for different downlink or uplink beams;

[0233] Configure different model information sets for different logical channels (such as PDCCH, PDSCH, PBCH, PUCCH, PUSCH, PRACH, etc.);

[0234] Targeting different model functions (such as CSI feedback, beam management, positioning, channel estimation, signal detection, etc.).

[0235] The functions of different intervals / channels / models are reflected through MAC CE signaling (for example, they are distinguished by LCID, or indication fields such as BWP ID / TCI ID are included in MAC CE).

[0236] When the model activated / selected by MAC CE from the model information set includes only one candidate model, the model indication is completed only through RRC and MAC CE signaling, and no further indication is required through UCI signaling.

[0237] S4. Complete model ID indication through UCI

[0238] The UE can directly activate / select the model in the model information set configured by RRC through UCI (i.e., the model ID indication is jointly completed by RRC and DCI), or it can indicate the final model in the model selected by MAC CE (i.e., the model ID indication is jointly completed by RRC, MAC CE and DCI).

[0239] In the case where there are multiple model information sets configured through RRC or MAC CE (different sets correspond to different frequency domain / spatial domain intervals or logical channels, model functions, etc.), the UE can use different fields of UCI to indicate the models separately.

[0240] For the case where there is only a single, public model information set, the UE can indicate models for different frequency / spatial domain intervals or logical channels, or corresponding to different model types or functions through different fields of UCI signaling.

[0241] In the above application examples 1 and 2, the base station or UE independently completes the model indication. In other application examples, the base station and UE can collaboratively and interactively complete the model indication. This approach will bring greater freedom to the system and is also a possible development direction. Possible examples include but are not limited to:

[0242] (1) The base station configures the model information set through RRC signaling, and then selects / activates several candidates from it through MAC CE signaling. The UE completes the model indication through UCI (as shown in Figure 14A).

[0243] (2) The UE configures the model information set through RRC signaling, and the base station selects / activates several candidates from them through MAC CE signaling, and then completes the model indication through DCI (as shown in Figure 14B).

[0244] (3) The base station configures the model information set through RRC signaling, and the UE selects / activates several candidates through MAC CE signaling. The base station then completes the model indication through DCI.

[0245] (4) The base station configures the model information set through RRC signaling, and the UE completes the model indication through UCI.

[0246] Combined with the above application examples, it can be seen that the hierarchical information indication method proposed in this application can better balance the contradiction between the flexibility of model indication and the transmission resource overhead, taking into account the efficiency and flexibility of model indication signaling. When it is necessary to implement model switching quickly and at a high frequency (such as millisecond level, slot level), it is only necessary to use a small number of bits through the first signaling to indicate the model within the model candidate range configured by the second signaling. Only when the model candidate range undergoes large-scale changes, it is necessary to update it through the second signaling.
