[0142] The access network device 120 is a device having a wireless transceiver function and configured to communicate with the terminal device 110. The access network device may be a node in a radio access network (RAN), and may be referred to as a RAN node or a network device, or may be referred to as a base station.

[0145] In this embodiment of the application, the apparatus configured to realize the function of the access network device may be the access network device, or may be an apparatus, such as a chip system, that can support the access network device in realizing the function. The apparatus may be mounted on the access network device or may be used together with the access network device.

[0146] In this embodiment of the application, the terminal device may further have AI processing capability, and the access network device may also have AI processing capability. This is applicable to scenarios where AI and communication are combined. A possible scenario where AI and communication are combined is an AI communication transceiver. As shown in Figure 3, one or more modules of the transmitter and receiver are realized through an AI model (e.g., neural network) to obtain good global performance.

[0147] The current combination of AI and communication is mainly to design an AI model or training method for a given system parameter in a specific scenario. When the environment such as device capability, scenario (e.g., channel condition) or system parameter changes, the corresponding model needs to be redesigned and retrained, making it difficult to deploy and use the combination of AI and communication in a universal communication system.

[0148] To solve the above problems, the embodiments of this application provide a communication method, related apparatus and system for adapting to environmental changes such as channel conditions and user requirements and achieving effective data reception and transmission.

[0149] 4 is a diagram of an architecture of a communication system according to an embodiment of this application. As shown in FIG. 4, the architecture of the communication system includes a first processing module 410, a second processing module 420, a third processing module 430, a first interface 440, and a second interface 450. The first processing module 410 acquires and processes data 1 to acquire data 2, and transmits data 2 to the second processing module 420 through the first interface 440. The second processing module 420 acquires and processes data 2 to acquire data 3, and transmits data 3 to the third processing module 430 through the second interface 450. The third processing module 430 acquires and processes data 2 to acquire data 4.

[0150] The first processing module 410 may be located at a transmitting end, and the data 1 may be a bit stream or a symbol. For example, the first processing module 410 may perform one or more operations such as source coding, channel coding, modulation, and multiple-input multiple-output (MIMO) precoding on the data 1, or an operation equivalent to one or more of the above operations. The third processing module 430 may be located at a receiving end. For example, the third processing module 430 may perform one or more operations such as demodulation, channel decoding, and source decoding on the obtained data 3, or an operation equivalent to one or more of the above operations, to obtain data 4, and the data 4 may be a bit stream or a symbol obtained by recovering the data 1.

[0151] The first processing module 410 and / or the third processing module 430 may be realized through a neural network model. Optionally, the first processing module 410 and / or the third processing module 430 may be configured through offline pre-training by using a large amount of environmental data (such as channel data), and the training may no longer be performed during actual use or inference.

[0152] The first interface 440 defines the interaction procedures and / or signaling between the first processing module 410 and the second processing module 420. The second interface 450 defines the interaction procedures and / or signaling between the second processing module 420 and the third processing module 430. The first interface 440 and / or the second interface 450 may be logical interfaces or may be physical interfaces.

[0153] The second processing module 420 may also be called a self-adaptive module. In the communication process, adjustment may be performed based on environmental data. The above "adjustment" may be realized through neural network training, or may be realized by solving analytical expressions.

[0154] In the above communication architecture, the first processing module 410 and the third processing module 430 may be adjusted by using offline training, and the second processing module 420 may be adjusted based on actual environment changes. In this way, adaptation to environment changes can be realized with low complexity, and effective data reception and transmission can be realized.

[0155] The first processing module and the third processing module are obtained through offline training by using a large amount of environmental data. The communication device may pre-store one or more first processing modules and / or one or more third processing modules. Optionally, the one or more first processing modules and / or one or more third processing modules may be downloaded from a model server or provided by a third party. During actual use, the communication device may select the first processing module or the third processing module based on the computing capability, memory capability, power consumption and task type of the communication device. The second processing module is a module that can be locally configured in the communication device and adjusted based on real-time environmental data. As the communication environment changes, the input / output parameters, model parameters, etc. of the second processing module may change. This may cause incompatibility between the first processing module and the second processing module, or incompatibility between the third processing module and the second processing module. Therefore, when selecting the first processing module / third processing module and the second processing module, the communication device needs to consider the adaptation between the first processing module / third processing module and the second processing module. Furthermore, the communication devices at the transmitting end and the receiving end may respectively select a first processing module and a third processing module to jointly realize data reception and transmission, and adaptation is also required in the selection of the first processing module and the selection of the third processing module to realize effective communication.

[0156] Regarding the above problem, the embodiment of this application provides a registration procedure. The first processing module of the sending communication device may adapt to the second processing module in the communication device through the registration procedure, or may adapt to the third processing module of the receiving end by performing registration with the second processing module. The second processing module may be adjusted based on the actual transmission environment. This allows each processing module to complete data processing, adapt to the changing communication environment, and realize effective data reception and transmission.

[0157] In a possible realization manner, an interaction procedure and / or signaling between the processing entity and the self-adaptive entity may be defined through an interface between the processing entity and the self-adaptive entity, such as the above-mentioned first interface and second interface. The interaction procedure may include a registration process, a data transmission process, etc. Parameters related to the signaling may include identification information, data type, data precision, input dimension, output dimension, etc. transmitted between the processing entity and the self-adaptive entity.

[0158] The values ​​of the parameters related to the signaling defined by the first interface and the second interface may be predefined in a standard, or may be semi-statically or dynamically configured. In a possible implementation, the identification information may be related to a task type of a particular implementation. Optionally, the task type may be indicated by using radio resource control (RRC) signaling. For example, a task type or task identifier field is added to the RRC. In a possible implementation, the data type and data precision may be related to the performance requirements of the task. Optionally, the performance requirements of the task may be indicated by using RRC signaling. For example, a performance requirement field is added to the RRC. In a possible implementation, the input dimension and the output dimension may be related to actual transmission resources, actual transmission policy, etc., and the transmission resources or transmission policy may be indicated by using downlink control information (DCI) signaling. The transmission policy may be a modulation and coding scheme (MCS). For example, parameters such as the number of information bits, the number of coded bits and the number of modulated modulation symbols are determined based on the transmission resources and the MCS level, and these parameters are used to determine the input dimension and / or the output dimension.

[0159] As shown in Fig. 5, an embodiment of this application provides a communication method 500. The method is applicable to a transmitting end and relates to a first control entity, a first processing entity and a second entity. The first control entity is configured to control or manage the first processing entity, the second entity, and the interaction between the first processing entity and the second entity. The first processing entity and the second entity correspond to the first processing module 410 and the second processing module 420, respectively, in the communication architecture shown in Fig. 4. A model corresponding to the first processing entity may be obtained through offline training, and a model corresponding to the second entity may be adjusted based on environment information. The first control entity, the first processing entity and the second entity may be physically located in the same communication device or different communication devices.

[0164] In a possible implementation, the first control entity is a protocol layer entity above the physical layer, which may also be referred to as an upper layer entity, for example, the first control entity is a media access control (MAC) layer entity, and the registration indication is MAC layer signaling.

[0165] S501: A first processing entity sends a first registration request to a second entity, and in response, the second entity receives the first registration request, where the first registration request includes a first identifier.

[0166] In a possible implementation, the first processing entity sends a first registration request to the second entity based on the first registration instruction received in S500.

[0167] In another possible implementation, the first processing entity selects the second entity based on a task type corresponding to the first processing entity, and sends a first registration request to the second entity.

[0168] Specifically, the first identifier indicates one or more of the following information of the first processing entity: model information or data information.

[0169] The model information may be referred to as a model description and may include one or more of the following: model purpose, model type, model scale, model accuracy, or model performance.

For example, the model objective includes one or more of the following: quantization, source coding, channel coding, modulation, and MIMO precoding.

The inference performance of the model may be represented by the precision of the inference performed by the model on a reference dataset.

[0171] The data information may be referred to as a data description. The data information may include one or more of the following: data type, data dimension, and data precision.

[0173] S502: The second entity sends a first registration response to the first processing entity, and in response, the first processing entity receives the first registration response, where the first registration response includes input parameters of the second entity.

[0174] Specifically, the second entity determines whether the model information and / or data information of the first processing entity meets the requirements of the second entity based on the first identifier in the received first registration request, and when it determines that the model information and / or data information of the first processing entity meets the requirements of the second entity, it sends a first registration response to the first processing entity.

[0175] Alternatively, when the first processing entity determines that the model information and / or data information does not meet the requirements of the second entity, the second entity may feed back a registration failure indication to the first processing entity, and optionally, the first processing entity reports the registration failure indication to the first control entity.

[0176] Alternatively, when the first processing entity determines that the model information and / or data information does not meet the requirements of the second entity, the second entity may not feed back a registration failure indication and may implicitly indicate a registration failure. When sending the first registration request, the first processing entity starts a first registration response time measurement. If the first registration response is received before the time measurement expires, the time measurement is reset. If the time measurement expires, a first registration response timeout indication is sent to the first control entity.

[0177] In a possible implementation, the input parameters of the second entity include one or more of the following aspects of the input data of the second entity: type, dimension or precision.

[0179] The output parameters of the first processing entity include one or more of the following aspects of the output data of the first processing entity: type, dimension or precision.

[0180] Specifically, before sending the first response acknowledgment, the first processing entity determines whether the output parameters of the first processing entity are compatible with the input parameters of the second entity, e.g., whether the type of output data of the first processing entity is compatible with the type of input data of the second entity, whether the dimension of the output data of the first processing entity is compatible with the dimension of the input data of the second entity, and / or whether the precision of the output data of the first processing entity is compatible with the precision of the input data of the second entity.

[0181] When the first processing entity determines that the output parameters of the first processing entity are successfully matched with the input parameters of the second entity, the first processing entity sends a first response acknowledgment to the second entity (S503a). If the match fails, the first processing entity sends a first response acknowledgment to the first control entity (S503b).

[0182] S503a: The first processing entity sends a first response acknowledgment to the second entity, where the first response acknowledgment indicates that the output parameters of the first processing entity successfully match the input parameters of the second entity, and in response, the second entity receives the first response acknowledgment.

[0183] In a possible implementation, after determining that the output parameters of the first processing entity successfully match the input parameters of the second entity, the first processing entity performs a first processing on the first input data to obtain first output data, and transmits the first output data to the second entity through the first interface.

[0184] For details of the data processing and data transmission processes of the first processing entity, the second entity and the third processing entity, please refer to the following related description in FIG.

[0185] S503b: The first processing entity sends a first response acknowledgment response to the first control entity, where the first response acknowledgment response indicates that an output parameter of the first processing entity is incompatible with an input parameter of the second entity, and in response, the first control entity receives the first response acknowledgment response.

[0186] Optionally, when the first processing entity determines that the output parameters of the first processing entity are incompatible with the input parameters of the second entity, the first processing entity may feed back a parameter compatibility failure indication to the second entity.

[0187] Alternatively, the first processing entity may not feed back a parameter match failure indication after determining that the output parameters of the first processing entity are not compatible with the input parameters of the second entity. When sending the first registration response, the second entity starts a first response acknowledgement time measurement. If the first response acknowledgement is received before the time measurement expires, the time measurement is reset. If the time measurement expires, a first response acknowledgement timeout indication is sent to the first control entity. The second entity learns of the parameter match failure in an implicit manner, so that signaling overhead can be reduced.

[0188] The parameters of the model corresponding to the first processing entity may be obtained through offline training, and the parameters of the model corresponding to the second entity may be adjusted based on the environment information. In the actual communication process, the first processing entity does not need to retrain the model of the first processing entity, but performs registration with the appropriate second entity through the registration procedure shown in Fig. 5 (the model information and / or data information match, and the input parameters match the output parameters), and then performs data processing and transmission. According to the method, adaptation to changes in the actual environment can be realized with low complexity, and effective data reception and transmission can be realized.

[0189] As shown in FIG. 6, an embodiment of this application provides a communication method 600. The method is applicable to a receiving end and relates to a third control entity, a third processing entity and a second entity. The third control entity is configured to control or manage the third processing entity, the second entity, and the interaction between the third processing entity and the second entity. The third processing entity and the second entity correspond to the third processing module 430 and the second processing module 420, respectively, in the communication architecture shown in FIG. 4. A model corresponding to the third processing entity may be obtained through offline training, and a model corresponding to the second entity may be adjusted based on environment information. The third control entity, the third processing entity and the second entity may be physically located in the same communication device or different communication devices. The communication device may be the above-mentioned terminal device or access network device.

[0190] The specific contents of the communication method 600 will be described below.

[0191] S600 (optional step): The third control entity sends a second registration instruction to the third processing entity, and in response, the third processing entity receives the second registration instruction, where the second registration instruction includes identification information of the second entity.

[0192] In a possible implementation, the third control entity selects a third processing entity from the one or more processing entities, selects a second entity from the one or more self-adaptive entities, and sends a registration instruction including identification information of the second entity to the third processing entity.

[0193] Optionally, the third control entity selects the third processing entity and the second entity based on a task type, which may correspond to one or more of the following: demodulation, channel decoding, and source decoding.

[0194] In a possible implementation, the third control entity is a protocol layer entity above the physical layer, which may also be referred to as an upper layer entity. For example, the third control entity is a MAC layer entity, and the registration indication is MAC layer signaling.

[0195] When the first processing entity and the third processing entity jointly realize data reception and transmission, the third control entity interacts with the first control entity through an interaction mechanism of a protocol layer (e.g., a MAC layer protocol) corresponding to the third control entity to ensure that the third processing entity and the first processing entity are registered with the same second entity.

[0196] S601: A third processing entity sends a second registration request to a second entity, and in response, the second entity receives the second registration request, where the second registration request includes a first identifier.

[0197] In a possible implementation, the third processing entity sends a second registration request to the second entity based on the second registration instruction received in S600.

[0198] In another possible implementation manner, the third processing entity selects the second entity based on a task type corresponding to the third processing entity, and sends a second registration request to the second entity.

[0199] In particular, the first identifier indicates one or more of model information or data information of the third processing entity.

[0200] The model information may be referred to as a model description and may include one or more of the following: model purpose, model type, model scale, model accuracy, or model performance.

[0201] The model objective indicates the task type corresponding to the third processing entity. For example, the model objective includes one or more of the following: demodulation, channel decoding and source decoding. For other model information, please refer to the related description in S501. Details will not be described again here.

[0202] The data information may be referred to as a data description. The data information may include one or more of the following: data type, data dimension, and data precision.

[0203] The data type indicates the type of data that can be processed by the model. The data dimension indicates the input dimension and / or output dimension of the model. The data dimension may include the number of elements in the input data vector or the number of elements in the output data vector. For other description parameters related to the data information, please refer to the related description in S501. The details will not be described again here.

[0204] S602: The second entity sends a second registration response to the third processing entity, and in response, the third processing entity receives the second registration response, where the second registration response includes output parameters of the second entity.

[0205] In a possible implementation, the output parameters of the second entity include one or more of the type, dimension or precision of the output data of the second entity.

[0206] For other aspects of the second entity sending the second registration response to the third processing entity, please refer to the relevant description of the second entity sending the first registration response to the first processing entity in S502, and the details will not be described again here.

[0207] Optionally, when the third processing entity determines that the model information and / or data information does not meet the requirements of the second entity, the second entity may feed back a registration failure indication to the third processing entity, and optionally, the third processing entity reports the registration failure indication to the third control entity.

[0208] Alternatively, when the third processing entity determines that the model information and / or data information does not meet the requirements of the second entity, the second entity may not feed back a registration failure indication and may implicitly indicate a registration failure. When sending the second registration request, the third processing entity starts a second registration response time measurement. If a second registration response is received before the time measurement expires, the time measurement is reset. If the time measurement expires, a second registration response timeout indication is sent to the third control entity.

[0209] S603 (not shown separately in the drawings): The third processing entity sends a second response acknowledgment response based on the received second registration response, where the second response acknowledgment response indicates whether the output parameters of the third processing entity match the input parameters of the second entity.

[0210] The input parameters of the third processing entity include one or more of a type, a dimension or a precision of the input data of the third processing entity.

[0211] Specifically, before sending the second response acknowledgment, the third processing entity determines whether the input parameters of the third processing entity are compatible with the output parameters of the second entity, e.g., whether the type of input data of the third processing entity is compatible with the type of output data of the second entity, whether the dimension of the input data of the third processing entity is compatible with the dimension of the output data of the second entity, and / or whether the precision of the input data of the third processing entity is compatible with the precision of the output data of the second entity.

[0212] When the third processing entity determines that the input parameters of the third processing entity are successfully matched with the output parameters of the second entity, the third processing entity sends a second response acknowledgment to the second entity (S603a). If the match fails, the third processing entity sends a second response acknowledgment to the third control entity (S603b).

[0213] S603a: The third processing entity sends a second response acknowledgment to the second entity, where the second response acknowledgment indicates that the input parameters of the third processing entity successfully match the output parameters of the second entity, and in response, the second entity receives the second response acknowledgment.

[0214] In a possible implementation manner, after determining that the input parameters of the third processing entity are successfully matched with the output parameters of the second entity, the third processing entity receives the second output data transmitted by the second entity through the second interface, and performs a second processing on the second output data to obtain the third data. For specific content, please refer to the following related description in FIG. 10.

[0215] S603b: The third processing entity sends a second response acknowledgment to the third control entity, where the second response acknowledgment indicates that the input parameters of the third processing entity are incompatible with the output parameters of the second entity, and in response, the third control entity receives the second response acknowledgment.

[0216] Optionally, when it determines that the input parameters of the third processing entity are incompatible with the output parameters of the second entity, the third processing entity may feed back a parameter compatibility failure indication to the second entity.

[0217] Alternatively, the third processing entity may not feed back a parameter match failure indication when it determines that the input parameters of the third processing entity are not compatible with the output parameters of the second entity. When sending the second registration response, the second entity starts a second response acknowledgement time measurement. If the second response acknowledgement is received before the time measurement expires, the time measurement is reset. If the time measurement expires, a second response acknowledgement timeout indication is sent to the third control entity. The second entity learns of the parameter match failure in an implicit manner, so that signaling overhead can be reduced.

[0218] The model corresponding to the third processing entity may be obtained through offline training, and the model corresponding to the second entity may be adjusted based on the environment information. In the actual communication process, the third processing entity does not need to retrain the model of the third processing entity, but performs registration with the appropriate second entity through the registration procedure shown in Figure 6 (model information and / or data information match, and input parameters match output parameters), and performs data processing and transmission. According to this method, adaptation to changes in the actual environment can be realized with low complexity, and effective data reception and transmission can be realized.

[0219] In the communication method 500 and the communication method 600, three steps related to the registration process, namely, registration request, registration response and response acknowledgement, may cause registration failure, respectively. For example, registration response timeout, response acknowledgement timeout, or mismatch of input and output parameters between the two entities may cause the processing entity to fail to register with the second entity. For failure in any registration stage, the registration may be realized by selecting a new first processing entity / third processing entity to initiate the registration procedure with the second entity, or may be realized by initiating a new registration procedure with the new second entity by the first processing entity / third processing entity. Figures 7-9 describe some possible procedures after registration failure according to embodiments of this application.

[0220] As shown in Fig. 7, an embodiment of this application provides a communication method 700. The method describes a processing method for when a registration failure occurs after a first processing entity sends a registration request to a second entity. The communication method 700 is described by using an example in which a first processing entity is registered with a second entity, and is also applicable to a scenario in which a third processing entity is registered with the second entity. The method relates to a first control entity, a first processing entity, a second entity, and a fourth entity, where the fourth entity is similar to the second entity, and a model of the fourth entity may be modulated based on environment information.

[0221] The specific contents of the communication method 700 will be described below.

[0222] S700: The first control entity sends a first registration instruction to the first processing entity, and in response, the first processing entity receives the registration instruction, where the registration instruction includes identification information of the second entity.

[0223] S701: A first processing entity sends a first registration request to a second entity, and in response, the second entity receives the first registration request, where the first registration request includes a first identifier.

[0224] For the specific contents of S700 and S710, please refer to S500 and S501, and the details will not be described again here.

[0225] S702: When sending a first registration request, the first processing entity starts a first registration response time measurement.

[0226] When the first registration response sent by the second entity is received before the first registration response time measurement expires, the time measurement is stopped or reset. The time measurement period may be predefined.

[0227] When the first registration response time measurement expires, step S703 is executed.

[0228] S703: The first processing entity sends a first registration response timeout indication to the first control entity, and correspondingly, the first control entity receives the first registration response timeout indication.

[0229] S704: The first control entity sends a third registration instruction to the first processing entity, and in response, the first processing entity receives the third registration instruction, the third registration instruction including the identification information of the fourth entity.

[0230] Specifically, after receiving the first registration response timeout instruction, the first control entity selects another entity, i.e., a fourth entity, from the one or more self-adaptive entities, and sends a third registration instruction to the first processing entity, including identification information of the fourth entity.

[0231] Optionally, the fourth entity may alternatively be an entity obtained by updating the second entity based on an output parameter of the first processing entity.

[0232] S705: The first processing entity sends a third registration request to the fourth entity, and in response, the fourth entity receives the third registration request, where the third registration request includes the first identifier. For the specific content of S705, refer to S501. Details are not described again here.

[0233] In the method 700, after sending a first registration request, the first processing entity starts a first registration response time measurement. When the time measurement expires, the first processing entity reports a timeout indication to the first control entity. The first control entity indicates other self-adaptive entities to the first processing entity to avoid waiting for a long period of time and improve efficiency.

[0234] As shown in Fig. 8, an embodiment of this application provides a communication method 800. The method describes a processing method for subsequent operation after a registration failure occurs after the second entity sends a registration response to the first processing entity, for example, caused by a mismatch between an input parameter of the second entity and an output parameter of the first processing entity. The communication method 800 is described by using an example in which the first processing entity is registered with the second entity, and is also applicable to a scenario in which a third processing entity is registered with the second entity. The method relates to a first control entity, a first processing entity, a second entity, and a fourth entity, where the fourth entity is similar to the second entity, and a model of the fourth entity may be modulated based on environment information.

[0235] S800 (optional step): The first control entity sends a first registration instruction to the first processing entity, and in response, the first processing entity receives a registration instruction, where the registration instruction includes identification information of the second entity.

[0236] S801: A first processing entity sends a first registration request to a second entity, and in response, the second entity receives the first registration request, where the first registration request includes a first identifier.

[0237] S802: The second entity sends a first registration response to the first processing entity, and in response, the first processing entity receives the first registration response, where the first registration response includes input parameters of the second entity.

[0238] For a specific description of S800 to S802, please refer to S500 to S502. The details will not be described again here.

[0239] S803: The first processing entity sends a first response acknowledgment response to the first control entity, where the first response acknowledgment response indicates that an output parameter of the first processing entity is incompatible with an input parameter of the second entity, and in response, the first control entity receives the first response acknowledgment response.

[0240] The output parameters of the first processing entity include one or more of the following contents of the output data of the first processing entity: type, dimension or precision. Specifically, before sending the first response acknowledgment, the first processing entity determines whether the output parameters of the first processing entity are compatible with the input parameters of the second entity, for example whether the type of the output data of the first processing entity is compatible with the type of the input data of the second entity, whether the dimension of the output data of the first processing entity is compatible with the dimension of the input data of the second entity, and / or whether the precision of the output data of the first processing entity is compatible with the precision of the input data of the second entity.

[0241] When the first processing entity determines that the output parameters of the first processing entity are incompatible with the input parameters of the second entity, the first processing entity sends a first response acknowledgment to the first control entity.

[0242] S804: The first control entity sends a third registration instruction to the first processing entity, and in response, the first processing entity receives the third registration instruction, the third registration instruction including the identification information of the fourth entity.

[0243] Specifically, after receiving a first confirmation response indicating an adaptation failure, the first control entity selects another entity, i.e., a fourth entity, from the one or more self-adaptive entities and sends a third registration instruction including identification information of the fourth entity to the first processing entity.

[0244] S805: The first processing entity sends a third registration request to the fourth entity, and the fourth entity correspondingly receives the third registration request, where the third registration request includes the first identifier. For the specific content of S705, please refer to S501. Details will not be described again here.

[0245] In the method 800, when the first processing entity determines that the output parameters of the first processing entity are not compatible with the input parameters of the second entity indicated in the first registration response, the first processing entity sends a first acknowledgement response indicating the compatibility failure to the first control entity. The first control entity indicates to the first processing entity other self-adaptive entities with which the first processing entity can register, to avoid registering with the second entity multiple times. Thus, the efficiency is improved.

[0246] As shown in Fig. 9, an embodiment of this application provides a communication method 900. The method describes a subsequent operation after a registration failure caused by a timeout of a first registration response time measurement. The communication method 900 is described by using an example in which a first processing entity is registered with a second entity, and is also applicable to a scenario in which a third processing entity is registered with the second entity. The method relates to a first control entity, a first processing entity, a second entity, and a fourth processing entity, where the fourth processing entity is similar to the first processing entity, and a model corresponding to the fourth processing entity is obtained through offline training.

[0247] S900 (optional step): The first control entity sends a first registration instruction to the first processing entity, and in response, the first processing entity receives a registration instruction, where the registration instruction includes identification information of the second entity.

[0248] S901: A first processing entity sends a first registration request to a second entity, and in response, the second entity receives the first registration request, where the first registration request includes a first identifier.

[0249] S902: The second entity sends a first registration response to the first processing entity, and correspondingly, the first processing entity receives the first registration response, where the first registration response includes input parameters of the second entity.

[0250] For a specific description of S900 to S902, please refer to S500 to S502, and the details will not be described again here.

[0251] S903: When sending a first registration request, the second entity starts a first response acknowledgment response time measurement.

[0252] When the first response acknowledgment sent by the second entity is received before the first response acknowledgment time measurement expires, the time measurement is stopped or reset. The time measurement period may be predefined.

[0253] When the first acknowledgement response time measurement expires, step S703 is executed.

[0254] S904: The second entity sends a first response acknowledgement timeout indication to the first control entity, and correspondingly, the first control entity receives the first response acknowledgement timeout indication.

[0255] S905: The first control entity sends a fourth registration instruction to the fourth processing entity, and in response, the fourth processing entity receives the fourth registration instruction, where the fourth registration instruction includes identification information of the second entity.

[0256] Specifically, after receiving the first response acknowledgment timeout instruction, the first control entity selects a target processing entity different from the first processing entity, i.e., a fourth processing entity, from the one or more processing entities, and sends a fourth registration instruction to the fourth processing entity including an identifier of the second entity.

[0257] For the specific content of selecting a target processing entity from one or more processing entities by the first control entity, please refer to the relevant description in S500, and the details will not be described again here.

[0258] S906: The first processing entity sends a third registration request to the second entity, and in response, the second entity receives the third registration request, where the third registration request includes a third identifier.

[0259] Specifically, the fourth processing entity sends a third registration request to the second entity according to the received fourth registration instruction. The third registration request includes a third identifier. The third identifier indicates one or more of the model information or data information of the fourth processing entity. For specific content, refer to the relevant description of the first identifier in S501. Details will not be described again here.

[0260] The subsequent steps of the method 900 are the same as those after the second entity receives the first registration request of the first processing entity in the method 500. The details are not described again here. In the method 900, when the first processing entity does not feed back the first response acknowledgment to the second entity before the first response acknowledgment time measurement expires, the second entity reports a first response acknowledgment timeout indication to the first control entity. The first control entity selects another target processing entity for registering with the second entity to avoid the case where the first processing entity fails to register with the second entity multiple times. Thus, the efficiency is improved.

[0261] After the target processing entities at the transmitting end and the receiving end are registered with the target self-adaptive entity via any one of the above possible methods described in Fig. 5-9, the target processing entities may perform data processing and data receiving and transmitting. As shown in Fig. 10, an embodiment of this application provides a communication method 1000. The method is described by using a first processing entity, a second entity and a third processing entity as examples, where the first processing entity and the second entity may be located at the transmitting end, and the third processing entity may be located at the receiving end. The output parameters of the first processing entity match with the input parameters of the second entity, and the output parameters of the second entity match with the input parameters of the third processing entity. The first processing entity performs a first processing on the data, and the third processing entity performs a third processing on the data, and the third processing may be an inverse operation of the first processing.

[0262] The specific contents of the communication method 1000 will be described below.

[0263] S1001: A first processing entity performs a first process on first input data to obtain first output data.

[0264] In a possible implementation, the first processing entity realizes a coding and modulation function, the first processing including channel coding and modulation or an equivalent processing of channel coding and modulation, the first input data is a bit stream obtained through source coding, and the first output data is a modulation symbol sequence.

[0265] For example, the structure of the first processing entity is shown in FIG. 11, which includes an input adaptation module, a data space transformation module, an output adaptation module, and an optional parameter configuration module. The first input data corresponds to the input 1101 in the drawing and may be a bit stream obtained through source coding. The input adaptation module is configured to perform feature embedding and extraction on the input 1101, so that the input 1101 adapts to the input dimension of the data space transformation module. The output of the input adaptation module is a bit group, and the data amount of bits in each group corresponds to the input dimension of the data space transformation module. The data space transformation module is configured to perform a subspace transformation on the output of the input adaptation module to obtain a modulation symbol sequence to realize the coding and modulation function. The parameters of the data space transformation module (including the input dimension of the data space transformation module) may be determined based on one or more of the following: a channel coding code rate, a modulation order, and a number of transmission resources. Optionally, the parameter configuration module is configured to configure the parameters of the data space transformation module based on one or more of the following: a channel coding code rate, a modulation order, and a number of transmission resources. The output adaptation module is configured to adapt the output of the data space transformation module to a particular data type, a particular data dimension and a particular data precision to obtain the first output data, ie, the output 1102 .

[0266] For example, the input configuration module is configured to adapt a dimension of the first input data to an input dimension of the data space transformation module. The data space transformation module is configured to perform a first process on the first input data to obtain first intermediate output data. The output adaptation module is configured to perform a dimensional transformation on the first intermediate output data to obtain first output data. The dimensional transformation on the first intermediate output data may include a change from a lower dimension to a higher dimension. For example, the dimensionality increase is achieved by replicating the first intermediate output data to address poor channel conditions.

[0267] In a possible implementation, the first processing entity realizes quantization, source coding, channel coding and modulation functions. The first processing includes quantization, source coding, channel coding and modulation, or includes equivalent processes of quantization, source coding, channel coding and modulation, the first input data is a symbol sequence, and the first output data is a modulation symbol sequence. Optionally, the first input data is sensing data.

[0268] For example, the structure of a first processing entity is shown in FIG. 11, which includes an input adaptation module, a data space transformation module, an output adaptation module, and an optional parameter configuration module. The first input data corresponds to the input 1101 in the figure and may be a symbol sequence. The input adaptation module is configured to perform feature embedding and extraction on the input 1101, so that the input 1101 adapts to the input dimension of the data space transformation module. The output of the input adaptation module is a symbol group, and the number of symbols in each group corresponds to the input dimension of the data space transformation module. The data space transformation module is configured to perform a subspace transformation on the output of the input adaptation module to obtain a modulation symbol sequence to realize the quantization, source coding, channel coding and modulation functions. The parameters of the data space transformation module (including the input dimension of the data space transformation module) may be determined based on one or more of the following: a quantization level, a source coding scheme, a channel coding code rate, a modulation order, and a number of transmission resources. Optionally, the parameter configuration module is configured to configure the parameters of the data space transformation module based on one or more of the following: a channel coding code rate, a modulation order, and a number of transmission resources. The output adaptation module is configured to adapt the output of the data space transformation module to a particular data type, a particular data dimension and a particular data precision to obtain the first output data, ie, the output 1102 .

[0269] In a possible implementation, the data space transformation module is a neural network model, and the first processing entity is obtained through offline training.

[0270] S1002: A first processing entity transmits first output data through a first interface, and correspondingly, a second entity receives the first output data through the first interface.

[0271] S1003: The second entity executes a second process on the first output data to obtain second output data.

[0272] In a possible implementation, the second process includes mapping the first output data to the second output data, the mapping from the first output data to the second output data being determined based on the real-time environmental parameters.

[0273] For example, the second entity corresponds to the second processing module in Fig. 4. The structure of the second processing module is shown in Fig. 12, and includes an input node, an output node, and a wireless channel. The number of input nodes corresponds to the input dimension of the second entity, and the number of output nodes corresponds to the output dimension of the second entity.

[0274] The possible types of mappings between input nodes and output nodes may be expressed as follows:

number

[0275] x j is the jth input value, j ∈ J, where J is the number of input nodes, and y i is the i-th output value, i ∈ I, I is the number of output nodes, and w ji is the weight between the jth input value and the ith output value. jimay be adjusted based on real-time environmental parameters, and may be updated by using, for example, a message passing algorithm (MPA), belief propagation (BP), minimum mean square error (MMSE), weighted minimum mean square error (WMMSE), maximum likelihood (ML), maximum a posteriori (MAP) or other algorithms. The above mapping formula is an example of a basic formula. In practical applications, the above mapping formula may be transformed, etc., which is not limited in this application.

[0276] S1004: The second entity transmits second output data to the third processing entity through the second interface, and correspondingly, the third processing entity receives the second output data.

[0277] S1005: A third processing entity performs a third process on the second output data to obtain third data.

[0278] In a possible implementation, the first processing entity realizes the coding and modulation functions, and correspondingly the third processing entity realizes the demodulation and channel decoding functions. The third processing may be understood as the reverse process of the first processing. The input of the third processing entity, i.e. the second output data, is a symbol sequence, and the output of the third processing entity, i.e. the third data, is a bit sequence.

[0279] For example, the structure of the third processing entity is shown in FIG. 11, which includes an input adaptation module, a data space transformation module, an output adaptation module, and an optional parameter configuration module. The second output data corresponds to the input 1101 in the drawing and may be a modulation symbol sequence. The input adaptation module is configured to perform feature embedding and extraction on the input 1101, so that the input 1101 adapts to the input dimension of the data space transformation module. The output of the input adaptation module is a symbol group, and the number of symbols in each group corresponds to the input dimension of the data space transformation module. The data space transformation module is configured to perform a subspace transformation on the output of the input adaptation module to obtain a modulation symbol sequence to realize demodulation and channel decoding functions. The parameters of the data space transformation module (including the input dimension of the data space transformation module) may be determined based on one or more of the following: a channel coding code rate, a modulation order, and a number of transmission resources. Optionally, the parameter configuration module is configured to configure the parameters of the data space transformation module based on one or more of the following: a channel coding code rate, a modulation order, and a number of transmission resources. The output adaptation module is configured to adapt the output of the data space transformation module to a subsequent module to obtain an output 1102 .

[0280] In a possible realization, the first processing entity realizes the quantization, source coding, channel coding and modulation functions and correspondingly the third processing entity realizes the demodulation, channel decoding and source decoding functions. The input of the third processing entity, i.e. the second output data, is a modulation symbol sequence and the output of the third processing entity, i.e. the third data, is a symbol sequence.

[0281] For example, the structure of the third processing entity is shown in FIG. 11, which includes an input adaptation module, a data space transformation module, an output adaptation module, and an optional parameter configuration module. The first output data corresponds to the input 1101 in the drawing and may be a modulation symbol sequence. The input adaptation module is configured to perform feature embedding and extraction on the input 1101, so that the input 1101 adapts to the input dimension of the data space transformation module. The output of the input adaptation module is a symbol group, and the number of symbols in each group corresponds to the input dimension of the data space transformation module. The data space transformation module is configured to perform a subspace transformation on the output of the input adaptation module to obtain a modulation symbol sequence, thereby realizing the quantization, source coding, channel coding and modulation functions. The parameters of the data space transformation module (including the input dimension of the data space transformation module) may be determined based on one or more of the quantization level, the source coding scheme, the channel coding code rate, the modulation order, and the number of transmission resources. Optionally, the parameter configuration module is configured to configure parameters of the data space transformation module based on one or more of the following: a channel coding code rate, a modulation order, and a number of transmission resources. The output adaptation module is configured to adapt an output of the data space transformation module to a subsequent module to obtain an output 1102.

[0282] In a possible implementation, the data space transformation module is a neural network model, and the third processing entity is obtained through offline training.

[0283] In a possible implementation, the first input data is sensing data, and the third data is sensing data restored by a third processing entity. Optionally, a communication device corresponding to the third processing entity may further process the sensing data to obtain a sensing result.

[0284] In the communication method 1000, data processing and data reception and transmission may be realized via a first processing entity, a second entity, and a third processing entity that are adapted to each other. The first processing entity and the third processing entity may be obtained through offline training, and the second entity may be adjusted based on real-time environmental parameters. In this way, adaptation to a changing transmission environment can be realized with low complexity, and effective data reception and transmission can be realized.

The first processing module 410 corresponds to the first processing entity, the second processing module 420 corresponds to the second entity, and the third processing module 430 corresponds to the third processing entity.

[0286] The first processing module 410 includes a neural network model NN Tx, and the third processing module 430 includes a neural network model NN Rx. NN Tx and NN Rx may be realized by using an autoencoder or a transformer, and are obtained by performing offline pre-training based on a training sample generated through modeling based on a large-scale environmental parameter sample or a mathematical model.

[0287] The second processing module 420 includes an iterative algorithm module, a wireless channel module, and optional modules such as beamforming and MIMO precoding. The iterative operation module may perform online adjustment based on real-time environmental parameters.

[0288] In a possible implementation, the real-time environmental parameters are determined based on a feedback instruction of the third processing module. The feedback instruction includes channel state information or a channel eigenvector, and the channel eigenvector is an eigenvalue vector extracted based on the channel state information. Optionally, the feedback instruction further includes capability switching information, and the capability switching information is used to enable or disable the first processing module 410 and / or the second processing module 420.

[0289] In a possible implementation, the iterative algorithm module may be implemented via MPA, BP, MMSE, WMMSE, maximum likelihood ML, MAP or other algorithms.
