[0041] Generally speaking, traditional communication systems support a limited number of connections and are easy to implement.

Wearable devices may also be called wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0049] In an embodiment of the present application, the network device may be a device for communicating with a mobile device. The network device may be an access point (AP) in a WLAN, an evolved base station (eNB or eNodeB) in LTE, or a relay station or access point, or a vehicle-mounted device, a wearable device, and a network device (gNB) in an NR network, or a network device in a future evolved PLMN network or a network device in an NTN network, etc.

The cell can be a cell corresponding to the network device (for example, a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0052] FIG1 exemplarily illustrates a communication system 100. The communication system includes a network device 110 and two terminal devices 120. In one embodiment, the communication system 100 may include multiple network devices 110, and each network device 110 may include a different number of terminal devices 120 within its coverage area, which is not limited in this embodiment of the present application.

[0053] In one embodiment, the communication system 100 may further include other network entities such as a Mobility Management Entity (MME) and an Access and Mobility Management Function (AMF), which is not limited in this embodiment of the present application.

[0054] Among them, the network equipment may include access network equipment and core network equipment. That is, the wireless communication system also includes multiple core networks for communicating with the access network equipment. The access network equipment can be an evolutionary base station (evolutional node B, abbreviated as eNB or e-NodeB) macro base station, micro base station (also called "small base station"), pico base station, access point (AP), transmission point (TP) or new generation base station (new generation Node B, gNodeB), etc. in a long-term evolution (LTE) system, a next-generation (mobile communication system) (next radio, NR) system or an authorized auxiliary access long-term evolution (LAA-LTE) system.

[0055] It should be understood that in the embodiments of the present application, a device having a communication function in a network / system may be referred to as a communication device. Taking the communication system shown in Figure 1 as an example, the communication device may include a network device and a terminal device having a communication function. The network device and the terminal device may be specific devices in the embodiments of the present application and will not be described in detail here. The communication device may also include other devices in the communication system, such as a network controller, a mobility management entity, and other network entities, which are not limited in the embodiments of the present application.

[0056] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

[0057] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association between A and B.

[0058] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0059] 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.

[0060] 5G or 6G air interface systems may activate or select AI / ML models for certain functions or features in appropriate application scenarios, replacing traditional non-AI / ML technical solutions. An example of a technical solution for activating and selecting an AI / ML model is as follows:

[0061] If an AI / ML model exists for a function and / or feature, the 5G or 6G system can configure it based on the terminal's reported capabilities. For example, a set of AI / ML models can be configured for activation, such as AI / ML model 1 and AI / ML model 2 as shown in Figure 2. The network can then select and activate an AI / ML model from this set of AI / ML models.

[0062] Different AI / ML models optimized for specific application scenarios may be suitable for different deployment scenarios. When the network detects that an AI / ML model is not performing well, it can indicate that it is switching to another AI / ML model. This process is called model switching. For example, as a terminal moves from one cell to another, the deployment scenario may change significantly, making the original AI / ML model unsuitable for the new deployment scenario. Upon detecting performance deterioration, the network needs to switch to another model that is more suitable for the current deployment scenario.

[0063] In one approach, the network can configure and select the AI / ML model through connection state indication information (such as Radio Resource Control (RRC) and Downlink Control Information (DCI)). However, the content of the DCI field required by the AI / ML algorithm is very different from that required by the non-AI / ML algorithm. If a DCI format is used to take into account both AI / ML operations and non-AI / ML operations, and a set of RRC configurations is used to accommodate the scheduling of both AI / ML and non-AI / ML resources, the overhead of this DCI format will be very large and the efficiency will be very low. For example, if the DCI needs to include both a field for non-AI / ML resource scheduling and a field for AI / ML reasoning and training, the DCI overhead will increase significantly. If indicators for activating AI / ML functions, features, or models are added to each AI / ML-related field in a DCI format, a large number of indicators need to be added, which will also cause a significant increase in DCI overhead. If these indicators are not included in the DCI format, dynamic activation / deactivation of AI / ML functions, features, or models cannot be achieved.

[0064] FIG3 is a schematic flow chart of a communication method 300 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 at least part of the following contents.

[0065] S310. A first communication device receives first downlink control information DCI, where the format of the first DCI is used to determine whether to activate an artificial intelligence configuration.

[0066] In an embodiment of the present application, a first communication device may receive a first DCI from a second communication device. In one example, the first communication device is a terminal device, and the second communication device is a network device. After receiving the first DCI from the network device, the terminal device may determine whether to activate an artificial intelligence configuration based on the format of the first DCI. By indicating whether to activate an artificial intelligence configuration using a first DCI having a specific format, the DCI can be dedicated to artificial intelligence configuration, reducing DCI overhead.

[0067] In one embodiment, the artificial intelligence configuration includes at least one of the following: configuration information of one or more artificial intelligence AI or machine learning ML functions; configuration information of one or more AI or ML characteristics; configuration information of one or more AI or ML models.

[0068] In one embodiment, the artificial intelligence configuration is carried in a radio resource control (RRC) configuration. In this embodiment of the present application, if the terminal device detects the first DCI, it can determine whether to use the AI ​​function, feature, or model based on the artificial intelligence configuration in the RRC configuration. The RRC configuration may include one or more. For example, the RRC configuration may include a first RRC configuration and a second RRC configuration.

[0069] In one embodiment, the format of the first DCI is a first format, and the first format is used to activate the first RRC configuration. In an embodiment of the present application, if the terminal device detects a first DCI with a first format, and the first RRC configuration includes configuration information of a first AI function, feature, or model, the terminal device may determine to start using the first AI function, feature, or model. If the terminal device detects a first DCI with a first format, and the first RRC configuration includes configuration information of multiple AI functions, features, or models, the terminal device may determine to start using all AI functions, features, or models configured in the first RRC configuration.

[0070] In one embodiment, the first DCI includes a first indicator; when the first indicator has a first value, it indicates activation of the first RRC configuration; and / or, when the first indicator has a second value, it indicates deactivation of the first RRC configuration. In this embodiment of the present application, if a terminal device detects a first DCI in a first format, and the first DCI includes a first indicator indicating whether to activate the first RRC configuration, if the value of the first indicator is the first value, such as 1, it may indicate activation of the first RRC configuration, that is, activation of the artificial intelligence configuration within the first RRC configuration. If the value of the first indicator is the second value, such as 0, it may indicate deactivation of the first RRC configuration, that is, deactivation of the artificial intelligence configuration within the first RRC configuration. For example, when all AI functions, features, and models configured in the first RRC configuration are activated, if the terminal device detects the first DCI in the first format, the terminal device may deactivate all AI functions, features, and models configured in the first RRC configuration. The specific values ​​of the first and second values ​​in this embodiment of the present application are merely examples and not limitations and may be flexibly changed in actual applications. For example, the first value is 0 and the second value is 1; the first value is 00 and the second value is 10, etc.

[0071] Figure 4 is a schematic flow chart of a communication method 400 according to another embodiment of the present application. The method may include one or more features of the above method. In one embodiment, the first DCI includes first resource scheduling information. The method further includes: S410, the first communication device uses a first RRC configuration within the resources scheduled by the first resource scheduling information.

[0072] In an embodiment of the present application, the first resource scheduling information may include time-frequency resource allocation information. If the terminal device detects a first DCI having a first format, at least one of all AI functions, features, or models configured in the first RRC configuration may be used only for the time-frequency resources scheduled by the first DCI.

[0073] In one embodiment, the step S410, in which the first communications device uses the first RRC configuration within the resources scheduled by the first resource scheduling information, includes:

[0074] S420: The first communications device sends or receives a first channel according to the artificial intelligence configuration in the first RRC configuration within the resources scheduled by the first resource scheduling information.

[0075] S430: When the sending or receiving on the first channel is completed, the first communication device stops using the artificial intelligence configuration in the first RRC configuration.

[0076] In an embodiment of the present application, the first channel may be an uplink channel or a downlink channel. If the first communication device is a terminal device and the second communication device is a network device, the first communication device may send an uplink channel to the second communication device according to the artificial intelligence configuration within the resources scheduled by the first resource scheduling information, or receive a downlink channel from the second communication device according to the artificial intelligence configuration. For example, assume that a first DCI with a first format schedules a first channel. The first channel is sent or received using all AI functions, features, or models configured in the first RRC configuration within the time-frequency resources scheduled by the first DCI.

[0077] In one embodiment, the first DCI includes a first indicator; when the first indicator is a first value, it indicates that the first RRC configuration is activated within the resources scheduled by the first resource scheduling information; and / or when the first indicator is a second value, it indicates that the first RRC configuration is deactivated within the resources scheduled by the first resource scheduling information. For example, if the value of the first indicator in the first DCI with a first format is a first value, such as 1, the artificial intelligence configuration in the first RRC configuration can be activated within the resources scheduled by the first resource scheduling information in the first DCI. If the value of the first indicator is a second value, such as 0, the artificial intelligence configuration of the first RRC configuration is deactivated within the resources scheduled by the first resource scheduling information in the first DCI.

[0078] In one embodiment, the first DCI includes a second indicator; when the second indicator is a third value, it indicates activation of the first RRC configuration; and / or, when the second indicator is a fourth value, it indicates activation of the second RRC configuration. In an embodiment of the present application, the terminal device may include multiple RRC configurations with artificial intelligence configurations, for example: a first RRC configuration and a second RRC configuration. When the terminal device detects a first DCI with a first format, it can determine which RRC configuration to activate based on the value of the second indicator in the first DCI. For example, if the value of the second indicator is a third value, such as 11, the artificial intelligence configuration in the first RRC configuration can be activated; if the value of the second indicator is a fourth value, such as 00, the artificial intelligence configuration in the second RRC configuration can be activated.

[0079] In one embodiment, the second indicator, when the fifth value is set, indicates deactivation of the RRC configuration. In this embodiment of the present application, if the terminal device has already activated one or more RRC configurations, deactivation can be performed using the second indicator in the first DCI. For example, if the terminal device has already activated the artificial intelligence configuration in the first RRC configuration, the second indicator has a fifth value, such as 10, which indicates deactivation of the artificial intelligence configuration in the first RRC configuration. For another example, if the terminal device has already activated the artificial intelligence configuration in the second RRC configuration, the second indicator has a fifth value, such as 11, which indicates deactivation of the artificial intelligence configuration in the second RRC configuration. For another example, if the terminal device has already activated the artificial intelligence configuration in the first RRC configuration and the second RRC configuration, the second indicator has a fifth value, such as 01, which indicates deactivation of the artificial intelligence configuration in the first RRC configuration and the second RRC configuration, or randomly deactivation of the artificial intelligence configuration in the first RRC configuration or the second RRC configuration. In addition, the second indicator can have two different values ​​to indicate whether to deactivate the artificial intelligence configuration in the first RRC configuration or the artificial intelligence configuration in the second RRC configuration.

[0080] In one embodiment, the first DCI includes a second indicator, and when the second indicator is a third value, it indicates that the first RRC configuration is activated within the resources scheduled by the first resource scheduling information in the first DCI; and / or, when the second indicator is a fourth value, it indicates that the second RRC configuration is activated within the resources scheduled by the first resource scheduling information in the first DCI. For example, the terminal device detects a first DCI with a first format. If the value of the second indicator is a third value, such as 11, the artificial intelligence configuration in the first RRC configuration can be activated within the resources scheduled by the first resource scheduling information in the first DCI; if the value of the second indicator is a fourth value, such as 00, the artificial intelligence configuration in the second RRC configuration can be activated within the resources scheduled by the first resource scheduling information in the first DCI.

[0081] In one embodiment, when the second indicator is a fifth value, it indicates that the RRC configuration is deactivated within the resources scheduled by the first resource scheduling information. For example, if the terminal device has activated the first RRC configuration and / or the artificial intelligence configuration in the second RRC configuration, the second indicator is a fifth value, such as 10, and the artificial intelligence configuration in one or more activated RRC configurations can be deactivated within the resources scheduled by the first resource scheduling information in the first DCI.

[0082] FIG5 is a schematic flow chart of a communication method 500 according to another embodiment of the present application. The method may include one or more features of the above method. In one embodiment, the method further includes:

[0083] S510: The first communication device receives a second DCI, where the format of the second DCI is used by the first communication device to determine not to activate an artificial intelligence configuration.

[0084] In an embodiment of the present application, different DCI formats can be used to indicate activation and deactivation of an AI configuration. For example, a first DCI in a first format indicates activation of an AI configuration, while a second DCI in a second format indicates deactivation of the AI ​​configuration. When a terminal device detects the second DCI in the second format, it deactivates the AI ​​configuration and uses traditional communication methods for subsequent processing.

[0085] In one embodiment, the format of the second DCI is a second format, and the second format is used to determine not to use the first RRC configuration. In the embodiment of the present application, the first format of the first DCI and the second format of the second DCI are different, for example, the first format is DCI Format 0 and the second format is DCI Format 1.

[0086] In one embodiment, the second DCI includes second resource scheduling information, and the second resource scheduling information is used to instruct the first communication device not to use the first RRC configuration within the resources scheduled by the second resource scheduling information.

[0087] For example, the terminal device detects a second DCI with a second format. According to the information of the second DCI, within the time-frequency resources scheduled by the second resource scheduling information in the second DCI, the artificial intelligence configuration in the second RRC configuration may not be used, but the traditional communication method may be used for subsequent processing.

[0088] In one embodiment, the second resource scheduling information is used to instruct the first communications device not to use the artificial intelligence configuration in the first RRC configuration to send or receive the second channel within the resources scheduled by the second resource scheduling information.

[0089] For example, assume that a first channel of a first DCI schedule with a first format and a second channel of a second DCI schedule with a second format are transmitted simultaneously. The first channel is sent or received using all AI functions, features, or models configured in the first RRC configuration within the time-frequency resources of the first DCI schedule. The second channel is sent or received without using the AI ​​functions, features, or models within the time-frequency resources of the second DCI schedule.

[0099] S720: When the sending or receiving of the first channel is completed, the second communication device stops using the artificial intelligence configuration in the first RRC configuration.

[0100] In one embodiment, the first DCI includes a first indicator; when the first indicator is a first value, it indicates that the first RRC configuration is activated within the resources scheduled by the first resource scheduling information; and / or, when the first indicator is a second value, it indicates that the first RRC configuration is deactivated within the resources scheduled by the first resource scheduling information.

[0104] In one embodiment, when the second indicator is the fifth value, it indicates that the RRC configuration is deactivated within the resources scheduled by the first resource scheduling information.

[0107] In one embodiment, the second DCI includes second resource scheduling information, and the second resource scheduling information is used to instruct the first communication device not to use the first RRC configuration within the resources scheduled by the second resource scheduling information.

[0108] In one embodiment, the method further includes: S820, the second communication device does not use the artificial intelligence configuration in the first RRC configuration to send or receive the second channel within the resources scheduled by the second resource scheduling information in the second DCI.

[0109] For specific examples of the second communication device executing methods 600, 700, and 800 of this embodiment, reference can be made to the relevant descriptions of the second communication device, such as the network device, in the above methods 300, 400, and 500. For the sake of brevity, they are not repeated here.

[0110] The communication method of the embodiment of the present application can provide a dedicated DCI format for AI / ML-based wireless air interface operations, which is specifically used to activate, deactivate and select AI / ML functions, features or models. In this way, the scheduling information of the AI / ML function, feature or model and the resource scheduling information using non-AI / ML algorithms can be included in one DCI format at the same time, thereby improving the signaling efficiency of DCI and avoiding increasing the DCI signaling overhead. In addition, the terminal can detect the DCI using the AI / ML dedicated DCI format and batch activate various AI / ML functions, features or models configured by RRC, which can further reduce the DCI overhead compared to using a large number of indicators in the DCI to activate each AI / ML function, feature or model separately.

[0111] The technical solutions of the embodiments of this application mainly include the following contents:

[0112] First, all AI functions, features, or models configured in the RRC are activated according to the AI-specific DCI Format. For example, the first DCI format (which can be an uplink DCI format, a downlink DCI format, or a sidelink DCI format) determines whether to use the AI ​​function, feature, or model based on the first RRC configuration when the terminal detects DCI with the first DCI format. The first RRC configuration includes configuration information of at least one AI function, feature, or model. When the terminal detects DCI with the first DCI format, if the first RRC configuration includes information about the first AI function, feature, or model, the terminal determines to start using the first AI function, feature, or model.

[0113] Second, batch activation of all AI functions, features, or models configured in the RRC according to the DCI Format. If the first RRC configuration contains information about multiple AI functions, features, or models, then when the terminal detects a DCI with the first DCI format, the terminal determines to start using all AI functions, features, or models configured in the first RRC configuration.

[0114] Activation mode solution 1: AI / ML dedicated scheduling DCI uses AI functions, features, or models once. For example, the first DCI format may include time-frequency resource allocation information. When the terminal detects DCI with the first DCI format, it uses all AI functions, features, or models configured in the first RRC configuration only for the time-frequency resources scheduled by this DCI.

[0115] The case where AI / ML-dedicated DCI and non-AI / ML-dedicated DCI are used simultaneously. For example, when a channel scheduled by a DCI with a first DCI format and a channel scheduled by a DCI with a second DCI format are transmitted simultaneously, all AI functions, features, or models configured in the first RRC configuration are used for the time-frequency resources scheduled by the DCI with the first DCI format, and no AI functions, features, or models are used for the time-frequency resources scheduled by the DCI with the second DCI format.

[0116] The AI / ML dedicated scheduling DCI selects from multiple sets of AI functions, features, or models. For example, the first DCI format includes a second indicator. When the second indicator is a first value, the AI ​​function, feature, or model configured in the first RRC configuration is selected. When the second indicator is a second value, the AI ​​function, feature, or model configured in the second RRC configuration is selected.

[0117] Activation mode scheme 2: Switch-type DCI activation of AI functions, features, or models. For example, when the terminal detects DCI with a first DCI format, the terminal determines to activate all AI functions, features, or models configured in the first RRC configuration. When all AI functions, features, or models configured in the first RRC configuration are in an activated state, and when the terminal detects DCI with the first DCI format, the terminal determines to deactivate all AI functions, features, or models configured in the first RRC configuration.

[0118] In some examples, the first DCI format does not include time-frequency resource allocation information.

[0119] The AI ​​function, feature or model is activated by the AI / ML switch DCI for the transmission of channels scheduled by non-AI / ML DCI. When the AI ​​function, feature or model configured in the first RRC configuration is in an activated state, the AI ​​function, feature or model configured in the first RRC configuration is used for the time-frequency resources scheduled by the DCI with the second DCI format. When the AI ​​function, feature or model configured in the first RRC configuration is in a deactivated state, the AI ​​function, feature or model is not used for the time-frequency resources scheduled by the DCI with the second DCI format. In some examples, the first DCI format includes a first indicator, and when the first indicator is a first value, the AI ​​function, feature or model configured in the first RRC configuration is activated; when the first indicator is a second value, the AI ​​function, feature or model configured in the first RRC configuration is deactivated.

[0120] The AI / ML switch DCI can select from multiple sets of AI functions, features, and models. For example, the first DCI format includes a second indicator. When the second indicator has a first value, the AI ​​function, feature, or model configured in the first RRC configuration is selected for use. When the second indicator has a second value, the AI ​​function, feature, or model configured in the second RRC configuration is selected for use. In some examples, when the second indicator has a third value, the AI ​​function, feature, or model is determined not to be used.

[0121] Example 1: Batch activation of all AI functions, features, or models configured by RRC based on the first DCI format

[0122] An example of the AI ​​function, feature, or model configuration of the first RRC configuration is shown in Table 1. Assume that among AI functions / features 1 to 6, the RRC configuration supports AI functions / features 1, 2, 4, and 5, but does not support AI functions / features 3 and 6.

[0123] For AI function / feature 1, RRC configuration uses AI / ML model 1-1;

[0124] For AI function / feature 2, RRC configuration uses AI / ML model 2-2;

[0125] For AI function / feature 4, RRC configuration uses AI / ML model 4-3;

[0126] For AI function / feature 5, RRC configuration uses AI / ML model 5-2.

[0127] Table 1: AI functions, features, or model configurations for the first RRC configuration

[0128] In the DCI, an indicator can be added for each AI function and / or feature, and the indicator value can be used to determine whether to use this AI function and / or feature. In the DCI, an indicator of the AI / ML model ID can also be added for each AI function and / or feature to indicate which AI / ML model to use for this AI function / feature. However, this approach will increase DCI overhead significantly.

[0129] The first DCI format of the embodiment of the present application may not include an indicator for the AI ​​function, feature or model, and the terminal detects this DCI format and directly activates various AI functions, features or models configured by RRC. As shown in Figure 9, all AI functions, features or models configured by RRC are batch activated based on the dedicated AI scheduling DCI format. For example, the terminal receives a DCI of the first DCI format (Format) when the AI ​​function, feature or model is not used. After receiving the DCI, the AI ​​functions, features or models that the terminal starts to use can be found in Table 1. For example, function / feature 1 supports the use of model 1-1; function / feature 2 supports the use of model 2-2; function / feature 3 does not support the use of model; function / feature 4 supports the use of model 4-3; function / feature 5 supports the use of model 5-2; function / feature 6 does not support the use of model.

[0130] This example uses a DCI format specifically for AI / ML, which can be used specifically to activate AI / ML functions, features, or models. This prevents a single DCI format from containing both scheduling information for AI / ML functions, features, or models and resource scheduling information for non-AI / ML algorithms. This improves DCI signaling efficiency and avoids increasing DCI signaling overhead. Furthermore, the terminal can detect DCI using the AI / ML-specific DCI format and batch activate various AI / ML functions, features, or models configured by RRC. This further reduces DCI overhead compared to using a large number of indicators in the DCI to activate each AI / ML function, feature, or model separately.

[0131] Example 2: Activate the RRC-configured AI function, feature, or model for the scheduled resources at one time based on a dedicated AI scheduling DCI.

[0132] In this example, the first DCI format contains time-frequency resource allocation information. When the terminal detects DCI with the first DCI format, all AI functions, features, or models configured in the first RRC configuration are used only for the time-frequency resources allocated by the DCI. As shown in Figure 10, based on the AI ​​dedicated scheduling DCI format, the AI ​​functions, features, or models configured by the RRC can be activated for the scheduled resources at one time. For example, when the terminal receives DCI using the first DCI format, it starts transmitting relevant channels (such as the physical downlink shared channel (PDSCH), physical uplink shared channel (PUSCH), physical uplink control channel (PUCCH), physical sidelink shared channel (PSSCH), etc.) in the scheduled resources according to the resource scheduling information in the DCI, and uses AI functions, features, or models in the transmission of these channels. The AI ​​functions, features, or models to be used can be found in Table 1. When the transmission of these channels is completed, for example, the transmission of the DCI-scheduled data in the first DCI format is completed, the AI ​​function, feature or model configured in the first RRC configuration is automatically stopped.

[0133] Optionally, the first DCI format may further include a first indicator, by which a selection can be made among multiple sets of AI functions, characteristics or models. As shown in Figure 11, based on the AI ​​dedicated scheduling DCI format, among multiple sets of AI functions, characteristics or models, the second DCI format can be selected as a DCI format for scheduling resources using non-AI / ML algorithms. For example, when the terminal receives a DCI in the first DCI format and the value of the first indicator in the DCI is 0, the transmission of the relevant channels (such as PDSCH, PUSCH, PUCCH, PSSCH, etc.) is started in the scheduled resources according to the resource scheduling information in the DCI, and the AI ​​functions, characteristics or models configured in the first RRC configuration are used in the transmission of these channels. The AI ​​functions, characteristics or models configured in the first RRC configuration that are started can be found in Table 1. When the transmission of these channels is completed, the AI ​​functions, characteristics or models configured in the first RRC configuration are automatically stopped. When the terminal receives a DCI in the first DCI format and the value of the first indicator in the DCI is 1, the terminal starts transmitting the relevant channels (such as PDSCH, PUSCH, PUCCH, PSSCH, etc.) in the scheduled resources according to the resource scheduling information in the DCI, and uses the AI ​​functions, features, or models configured in the second RRC configuration in the transmission of these channels. The AI ​​functions, features, or models configured in the first RRC configuration that is started may include: function / feature 1 supports the use of model 1-1; function / feature 2 supports the use of model 2-2; function / feature 3 supports the use of model 3-2; function / feature 4 supports the use of model 4-3; function / feature 5 supports the use of model 5-2; function / feature 6 supports the use of model 6-1. When the transmission of these channels is completed, the AI ​​functions, features, or models configured in the second RRC configuration are automatically stopped.

[0134] As shown in Figure 12, AI functions, features, or models may be used or not used for resources scheduled by dedicated AI and those scheduled by normal DCI, respectively. For example, when a channel scheduled by a first DCI format and a channel scheduled by a second DCI format are transmitted simultaneously, all AI functions, features, or models configured in the first RRC configuration are used for the transmission of the channel scheduled by the first DCI format (see Table 1 for examples of AI functions, features, or models used starting from the transmission of the channel scheduled by the first DCI format), and no AI functions, features, or models are used for the transmission of the channel scheduled by the second DCI format.

[0135] In this example, when the AI ​​function, feature or model configured by RRC is activated using DCI of the first DCI format, these AI functions, features or models are only used for the resources scheduled by this DCI. When the corresponding channel transmitted using the scheduled resources completes transmission, these functions, features or models are automatically stopped. This method can activate / deactivate AI functions, features or models in a targeted and on-demand one-time manner. It can avoid continuing to use these AI functions, features or models for channel transmission that is not suitable for these AI functions, features or models after the relevant channels have completed transmission, thereby improving the reliability of the system. When the channel scheduled by the first DCI format and the channel scheduled by the second DCI format are transmitted at the same time, the AI ​​functions, features or models can also be used for transmission on the channel scheduled by the first DCI format, and not for transmission on the channel scheduled by the second DCI format, which further improves the flexibility of the application of AI functions, features or models.

[0136] Example 3: Dedicated AI switch DCI activates AI functions, features, or models

[0137] In this example, the AI ​​function, feature, or model configured in the first RRC configuration is activated by the first DCI format for the transmission of the channel scheduled by the second DCI format. As shown in Figure 13, the dedicated AI switch DCI activates the AI ​​function, feature, or model for the transmission of the channel scheduled by the conventional DCI. For example, when the terminal receives a DCI in the first DCI format (optionally, the value of the first indicator included is 1), the AI ​​function, feature, or model configured in the first RRC configuration is activated. The AI ​​function, feature, or model to be used can be found in Table 1. When these AI functions, features, or models are in an activated state, the terminal receives a DCI in the second DCI format and can perform the channel transmission process scheduled by the DCI in the second DCI format, using these AI functions, features, or models for the time-frequency resources scheduled by this DCI. When the terminal receives a DCI in the first DCI format again (optionally, the value of the first indicator included is 0), the AI ​​function, feature, or model configured in the first RRC configuration is deactivated, that is, the AI ​​function, feature, or model is not used. When these AI functions, characteristics or models are in a deactivated state, the terminal receives DCI in the second DCI format and can perform the channel transmission process of the DCI scheduling in the second DCI format, and no longer uses the AI ​​functions, characteristics or models for the time-frequency resources scheduled by this DCI.

[0138] Optionally, the DCI of the first DCI format includes a first indicator. When the value of the first indicator is 1, the AI ​​function, feature or model configured in the first RRC configuration is activated; when the value of the first indicator is 0, the AI ​​function, feature or model configured in the first RRC configuration is deactivated.

[0139] Assume that a second RRC configuration is also configured, as shown in Table 2. The RRC configuration supports all AI functions / features 1, 2, 3, 4, 5, and 6.

[0140] For AI function / feature 1, RRC configuration uses AI / ML model 1-1;

[0141] For AI function / feature 2, RRC configuration uses AI / ML model 2-2;

[0142] For AI function / feature 3, RRC configuration uses AI / ML model 3-2;

[0143] For AI function / feature 4, RRC configuration uses AI / ML model 4-3;

[0144] For AI function / feature 5, RRC configuration uses AI / ML model 5-2;

[0145] For AI function / feature 6, RRC configuration uses AI / ML model 6-1.

[0146] Table 2: AI functions, features, or model configurations for the second RRC configuration

[0147] The selection may be made based on the first DCI format and the first RRC configuration and the second RRC configuration. For example, the terminal receives DCI in the first DCI format, which includes a second indicator. When the value of the second indicator is 01, the AI ​​function, feature, or model configured in the first RRC configuration is activated; when the value of the second indicator is 10, the AI ​​function, feature, or model configured in the second RRC configuration is activated; when the value of the second indicator is 00, the AI ​​function, feature, or model configured in the second RRC configuration is deactivated.

[0148] As shown in Figure 14, based on a dedicated AI switch-mode DCI, a selection can be made from among multiple RRC configurations of AI functions, features, or models. For example, when a terminal receives DCI in a first DCI format and the value of the second indicator included in the DCI is 01, the AI ​​functions, features, or models configured in the first RRC configuration are activated. The AI ​​functions, features, or models initially used can be found in Table 1. While these AI functions, features, or models are active, the terminal receives DCI in a second DCI format and can perform channel transmissions scheduled by the DCI in the second DCI format, using these AI functions, features, or models for the time-frequency resources scheduled by this DCI. When the terminal receives DCI in a first DCI format and the value of the second indicator included in the DCI is 10, the selection is made to the AI ​​functions, features, or models configured in the second RRC configuration. The AI ​​functions, features, or models initially used can be found in Table 2. While these AI functions, features, or models are active, the terminal receives DCI in a second DCI format and can perform channel transmissions scheduled by the DCI in the second DCI format, using these AI functions, features, or models for the time-frequency resources scheduled by this DCI. When the terminal receives DCI in a first DCI format and the value of the second indicator included in the DCI is 00, the AI ​​function, feature, or model is deactivated, that is, the AI ​​function, feature, or model is not used. When these AI functions, features, or models are in the deactivated state, the terminal receives DCI in a second DCI format and can perform the channel transmission process scheduled by the DCI in the second DCI format, and no longer uses the AI ​​function, feature, or model for the time-frequency resources scheduled by this DCI.

[0149] In this example, the first DCI format may not contain resource allocation information and is only used to activate / activate or select the AI ​​function, feature, or model configured by RRC, thereby achieving very low DCI signaling overhead. At the same time, since the AI ​​function, feature, or model configured by RRC is activated, these AI functions, features, or models can always remain activated until deactivated, avoiding the frequent transmission of dedicated AI switch DCI, further saving DCI overhead and PDCCH capacity.

[0150] A dedicated DCI format for AI / ML-based wireless air interface operations can be used in the communication method of an embodiment of the present application. This dedicated DCI format can be specifically used to activate, deactivate, and select AI / ML functions, features, or models, thereby avoiding a DCI format containing both scheduling information for AI / ML functions, features, or models and resource scheduling information for non-AI / ML algorithms, thereby improving the signaling efficiency of DCI and avoiding increasing DCI signaling overhead. At the same time, the terminal can detect DCI using an AI / ML-dedicated DCI format and batch activate various AI / ML functions, features, or models configured by RRC, which can further reduce DCI overhead relative to using a large number of indicators in the DCI to activate each AI / ML function, feature, or model separately.
