Description

Communication method and device Technical Field

[0001] The present application relates to the field of artificial intelligence technology, and in particular to a communication method and device. Background Art

[0002] Currently, in neural network-based transmitters and receivers, intelligent air interfaces can optimize transceiver signals through data-driven optimization. However, performance may vary in different scenarios due to differences in data distribution. To ensure communication performance, it may be necessary to switch to different neural network models or fall back from the intelligent air interface to the traditional air interface. On the other hand, due to changes in device computing or storage capabilities, it may be necessary to fall back from the intelligent air interface to the traditional air interface. Therefore, before and after the air interface switching, it may lead to waste of transmission resources and reduced transmission efficiency.

[0104] The following is a clear and complete description of the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative efforts are within the scope of protection of this application.

[0105] References to "one embodiment" or "some embodiments" in this application mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0106] In the description of this application, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "plurality" means two or more. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c can mean: a, b, c; a and b; a and c; b and c; or a, b, and c. Among them, a, b, and c can be single or multiple.

[0107] It is understood that in this application, "indication" can include direct indication, indirect indication, explicit indication, and implicit indication. When describing that a certain indication information is used to indicate A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0108] In this application, the information indicated by the indication information is referred to as the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated, etc., or the information to be indicated can be indirectly indicated by indicating other information, wherein there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved with the help of the arrangement order of each information agreed in advance (such as specified in the protocol), thereby reducing the indication overhead to a certain extent.

[0109] The information to be indicated can be sent as a whole or divided into multiple sub-information and sent separately. The transmission period and / or transmission timing of these sub-information can be the same or different. The specific transmission method is not limited in this application. The transmission period and / or transmission timing of these sub-information can be predefined, for example, according to a protocol, or can be configured by the transmitting device through sending configuration information to the receiving device.

[0110] It can be understood that "sending" and "receiving" in this application indicate the direction of signal transmission. For example, "sending information to XX" can be understood as the destination of the information is XX, which can include direct sending through the air interface, and also include indirect sending through the air interface by other units or modules. "Receiving information from YY" can be understood as the source of the information is YY, which can include direct receiving from YY through the air interface, and also include indirect receiving from YY through the air interface from other units or modules. "Sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface.

[0111] In other words, sending and receiving can be performed between devices, for example, between a network device and a terminal device, or can be performed within a device, for example, sending or receiving between components, modules, chips, software modules or hardware modules within the device through a bus, wiring or interface.

[0112] It is understandable that information may be processed between the source and destination of information transmission, such as coding, modulation, etc., but the destination can understand the valid information from the source. Similar expressions in this application can be understood similarly and will not be repeated.

[0120] Terminal equipment, also known as user equipment (UE), mobile station (MS), mobile terminal (MT), or customer premise equipment (CPE), is a device that includes wireless communication capabilities (providing voice and data connectivity to users). Examples include handheld devices, in-vehicle devices, and machine-type communication (MTC) terminals with wireless connectivity. Currently, terminal equipment can include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals used in industrial control, self-driving vehicles, remote medical surgery, smart grids, transportation safety, smart cities, and smart homes. For example, wireless terminals in unmanned driving can be drones, helicopters, or airplanes. For example, wireless terminals in the Internet of Vehicles can be onboard equipment, complete vehicle equipment, onboard modules, vehicles, or ships. Wireless terminals in industrial control can be cameras, robots, or robotic arms. Wireless terminals in smart homes can be televisions, air conditioners, vacuum cleaners, speakers, or set-top boxes.

[0121] It should be noted that the terminal device can be a device or apparatus with a chip, or a device or apparatus with integrated circuits, or a chip, module or control unit in the device or apparatus shown above, and this application does not limit this specifically.

[0122] A network device is a device deployed in a radio access network (RAN) to provide wireless communication capabilities for terminal devices. A network device can also be called an access network (RAN) entity, access node, network node, or communication device.

[0123] Specifically, the network device may be an access network device of a cellular system related to the 3rd Generation Partnership Project (3GPP). For example, a fourth-generation (4G) mobile communication system or a 5G mobile communication system. The network device may also be an access network device in an open access network (O-RAN or ORAN) or a cloud radio access network (CRAN). Alternatively, the network device may be an access network device in a communication system obtained by integrating two or more of the above communication systems.

[0124] The network equipment includes, but is not limited to, evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved NodeB, or home Node B, HNB), baseband unit (BBU), access point (AP) in wireless fidelity (WIFI) system, macro base station, micro base station, wireless relay node, donor node, wireless controller in CRAN scenario, wireless backhaul node, transmission point (TP) or transmission and receiving point (TRP). The network equipment can also be an access network equipment in a 5G mobile communication system. For example, a next generation NodeB (gNB) in a new radio (NR) system, a TRP, a TP, or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G mobile communication system. Alternatively, the network device may also be a network node constituting a gNB or a transmission point. For example, a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU may be configured separately or included in the same network element. For example, a BBU. The RU may be included in a radio frequency device or radio frequency unit. For example, in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). Alternatively, the network device may also be a server, a wearable device, a vehicle, or an on-board device. For example, in V2X technology, the network device may be a road side unit (RSU).

[0125] It should be noted that in different systems, CU (or CU-CP and CU-UP), DU or RU may have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called an open centralized unit (O-CU) or an open CU, DU may also be called an open distributed unit (O-DU), a centralized unit control plane (CU-CP) may also be called an open centralized unit control plane (O-CU-CP) or an open CU-CP, a centralized unit user plane (CU-UP) may also be called an open centralized unit user plane (O-CU-UP) or an open CU-UP, and RU may also be called an open radio unit (O-RU). This application does not limit this. Any of the CU, CU-CP, CU-UP, DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0126] Optionally, for network elements in the ORAN system, each network element may implement the protocol layer functions shown in Table 1 below.

[0127] Table 1

[0128] It should be noted that Table 1 above is merely an example. In actual applications, the protocol layer functions supported by each network element are not limited. For example, each network element may support more protocol layer functions, or the protocol layer functions supported by each network element may be specifically configured based on actual conditions. This application does not impose any specific limitations.

[0129] The following describes the architecture of the CU and DU of an access network device. The access network device includes at least one CU and at least one DU. Optionally, the access network device also includes at least one RU.

[0130] The following is an introduction using the example of an access network device including a CU and a DU. The CU has some functions of the core network, and the CU may include a CU-CP and a CU-UP. The CU and the DU may be configured according to the protocol layer functions of the wireless network they implement. For example, the CU is configured to implement the functions of the packet data convergence protocol (PDCP) layer and the protocol layers above it (for example, the RRC layer and / or the SDAP layer). The DU is configured to implement the functions of the protocol layers below the PDCP layer (for example, the RLC layer, the MAC layer, and / or the physical (PHY) layer). For another example, the CU is configured to implement the functions of the protocol layers above the PDCP layer (such as the RRC layer and / or the SDAP layer), and the DU is configured to implement the functions of the PDCP layer and the protocol layers below it (for example, the RLC layer, the MAC layer, and / or the PHY layer, etc.).

[0131] When a CU includes a CU-CP and a CU-UP, the CU-CP is used to implement the control plane functions of the CU, and the CU-UP is used to implement the user plane functions of the CU. For example, when the CU is configured to implement the functions of the PDCP layer, RRC layer, and SDAP layer, the CU-CP is used to implement the RRC layer functions and the control plane functions of the PDCP layer, and the CU-UP is used to implement the SDAP layer functions and the user plane functions of the PDCP layer.

[0132] The CU-CP can interact with the network elements in the core network for implementing control plane functions. The network elements in the core network for implementing control plane functions may be access and mobility function network elements, such as the access and mobility management function (AMF) in the 5G mobile communication system. The access and mobility function network element is responsible for mobility management in the mobile network, such as location update of the terminal device, registration network of the terminal device, switching of the terminal device, etc. The CU-UP can interact with the network elements in the core network for implementing user plane functions. The network elements in the core network for implementing user plane functions, such as the user plane function (UPF) in the 5G mobile communication system, are responsible for forwarding and receiving data in the terminal device.

[0133] The above configuration of CU and DU is only an example, and the functions of CU and DU can also be configured as needed. For example, the CU or DU can be configured to have the functions of more protocol layers, or the CU or DU can be configured to have partial processing functions of the protocol layer. For example, some functions of the RLC layer and the functions of the protocol layers above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are set in the DU. For another example, the functions of the CU or DU can be divided according to the service type or other system requirements. For example, according to the delay, the functions whose processing time needs to meet the smaller delay requirement are set in the DU, and the functions that do not need to meet the delay requirement are set in the CU.

[0134] The DU and RU can work together to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of the DU and RU can be configured in various ways according to the design. For example, the DU is configured to implement the baseband function, and the RU is configured to implement the mid-RF function. For another example, the DU is configured to implement the high-layer functions in the PHY layer, and the RU is configured to implement the low-layer functions in the PHY layer or to implement the low-layer functions and the RF functions. The high-layer functions in the physical layer may include a part of the functions of the physical layer, which is closer to the MAC layer, and the low-layer functions in the physical layer may include another part of the functions of the physical layer, which is closer to the mid-RF side.

[0135] Optionally, the network device may also be a core network device. The core network device is responsible for access control, registration management, service management, mobility management, etc. for terminal devices accessing the network. For example, the core network device is an AMF.

[0136] It should be noted that the network device can be the device or apparatus shown above, or it can be a component (for example, a chip), module, or unit in the device or apparatus shown above, and this application does not limit it specifically.

[0137] The communication system provided in the present application can introduce AI network elements to implement some or all AI-related operations. The AI ​​network element can also be called an AI node, AI device, AI entity, AI module, AI model, or AI unit, etc. The AI ​​network element can be a network element built into the communication system. For example, the AI ​​network element can be an AI module built into: an access network device, a core network device, a cloud server, or a network management (operation, administration and maintenance, OAM) to implement AI-related functions. The OAM can be a network management device as a core network device and / or a network management device as an access network device. Alternatively, the AI ​​network element can also be a network element independently set up in the communication system. Optionally, the terminal device or the chip built into the terminal device can also include an AI entity to implement AI-related functions. The following describes another communication system provided in an embodiment of the present application in conjunction with Figure 2A.

[0138] Please refer to Figure 2A, which is a schematic diagram of another communication system provided in an embodiment of the present application. As shown in Figure 2A, the network elements in the communication system are connected through interfaces (for example, NG interfaces, or Xn interfaces) or air interfaces. One or more AI modules are provided in these network element nodes (for example, core network equipment, access network nodes (RAN nodes), terminals or one or more devices in OAM) (for clarity, only one is shown in Figure 2A). The access network node can be a separate RAN node, or it can include multiple RAN nodes, for example, including CU and DU. One or more AI modules can also be provided in the CU and / or DU. Optionally, the CU can also be split into CU-CP and CU-UP. One or more AI models are provided in the CU-CP and / or CU-UP.

[0139] The AI ​​module is used to implement the corresponding AI function. The AI ​​modules deployed in different network elements can be the same or different. The model of the AI ​​module can implement different functions according to different parameter configurations. The model of the AI ​​module can be configured based on one or more of the following parameters: structural parameters (such as the number of neural network layers, the width of the neural network, the connection relationship between layers, the weight of the neuron, the activation function of the neuron, or at least one of the bias in the activation function), input parameters (such as the type of input parameters and / or the dimension of the input parameters), or output parameters (such as the type of output parameters and / or the dimension of the output parameters). Among them, the bias in the activation function can also be called the bias of the neural network.

[0140] An AI module can have one or more models. A model can infer an output, which includes one or more parameters. The learning, training, or inference processes of different models can be deployed on different nodes or devices, or on the same node or device.

[0141] It should be noted that the access network node shown in Figure 2A above can be taken as a whole, or the access network node shown in Figure 2A above adopts an architecture in which the CU and DU are separated. Please refer to Figure 2B, which is a schematic diagram of another communication system provided in an embodiment of the present application, as shown in Figure 2B, which shows a schematic diagram of a communication system in which the access network node is taken as a whole and the access network node is connected to a terminal device. Please refer to Figure 2C, which is a schematic diagram of another communication system provided in an embodiment of the present application, as shown in Figure 2C, which is a schematic diagram of a communication system in which the access network node adopts an architecture in which the CU and DU are separated.

[0142] The communication method provided in the embodiments of the present application is described in detail below in conjunction with the communication system shown in Figure 1, Figure 2A, Figure 2B or Figure 2C.

[0143] In order to better understand the solutions provided by the embodiments of the present application, some terms, concepts or processes involved in the embodiments of the present application are first introduced below.

[0144] 1. Neural Networks

[0145] A neural network (NN) is a specific model in machine learning technology. According to the universal approximation theorem, NNs can theoretically approximate any continuous function, enabling them to learn arbitrary mappings. Traditional communication systems require extensive expert knowledge to design communication modules. However, deep learning communication systems based on neural networks can automatically discover implicit patterns in massive data sets and establish mapping relationships between data, achieving performance superior to traditional modeling methods.

[0146] The idea of ​​neural networks comes from the neuron structure of brain tissue. For example, each neuron performs a weighted sum operation on its input value and outputs the operation result through an activation function. Please refer to Figure 3, which is a schematic diagram of a neuron structure provided by an embodiment of the present application. Assume that the input of the neuron is x = [x0, x1, ..., x n ], and the weights corresponding to each input are w=[w,w1,…,w n ], where n is a positive integer, w i and x i It can be a decimal, an integer (such as 0, a positive integer or a negative integer, etc.), or a complex number. i As x i The weight of x i Weighted. The bias of the weighted sum of the input values ​​according to the weight is, for example, b. The activation function can take many forms. Assuming that the activation function of a neuron is: y = f(z) = max(0,z), then the output of the neuron is: For another example, if the activation function of a neuron is: y = f(z) = z, then the output of the neuron is: b can be a decimal, an integer (eg, 0, a positive integer, or a negative integer), or a complex number, etc. The activation functions of different neurons in a neural network can be the same or different.

[0147] A neural network generally consists of multiple layers, each of which may include one or more neurons. Increasing the depth and / or width of a neural network can improve its expressive power, providing more powerful information extraction and abstract modeling capabilities for complex systems. The depth of a neural network can refer to the number of layers, and the number of neurons in each layer can be referred to as the width of that layer. In one implementation, a neural network includes an input layer and an output layer. The input layer processes the input information received by the neural network through neurons and passes the processing results to the output layer, which then produces the output of the neural network. In another implementation, the neural network includes an input layer, a hidden layer, and an output layer, as shown in the figure below. The input layer processes the input information received by the neural network through neurons and passes the processing results to an intermediate hidden layer. The hidden layer performs calculations on the received processing results to obtain a calculation result, which is then passed to the output layer or the next adjacent hidden layer, which ultimately produces the output of the neural network. A neural network can include one hidden layer or multiple hidden layers connected in sequence, without limitation.

[0148] A neural network is, for example, a deep neural network (DNN). Depending on how the network is constructed, a DNN can include a feedforward neural network (FNN), a convolutional neural network (CNN), and a recurrent neural network (RNN).

[0149] 2. Neural Network-Based Transmitters and Receivers

[0150] The transmitter and receiver based on the neural network can be optimized according to the scenario through data-driven training to achieve better transmission signal design and reception performance. Please refer to Figure 4, which is a schematic diagram of a communication process based on a neural network transceiver provided by an embodiment of the present application. Specifically, it can be the following modules: a bit processing module, that is, bit processing the transmission signal to obtain the bits to be transmitted; a DNN transmitter module, that is, the bits to be transmitted can be input into the deep neural network (DNN) transmitter to generate modulation symbols or signals to be transmitted; optionally, a waveform module, that is, waveform shaping processing can be performed on the signal after being processed by the transmitter; a channel module, that is, the waveform-processed signal reaches the receiver through the channel; a DNN receiver module, which receives the received signal through the DNN receiver. In which, the neural network can replace specific or multiple modules in the sending or receiving processing. For example, it can be used to optimize the channel coding, modulation, waveform, pilot and other modules in the transceiver signal processing. Please refer to Figure 5, which is a schematic flow chart of the signal processing of different modules optimized by a neural network provided in an embodiment of the present application. In Figure 5 (a), the neural network is used to optimize the modulation module and waveform. The transmitted bits are channel coded to obtain coded bits. After the coded bits are modulated by neural networks (NN-Mod), they are mapped to physical resources, transformed into time domain signals through inverse fast Fourier transform (IFFT), and then processed by a time-neural network (T-NN). Correspondingly, after the T-NN receives the signal, the receiving end performs IFFT transform on the signal, and then demodulates the transformed signal through neural networks (NN-DeM), and finally performs channel decoding processing. In Figure 5(b), a neural network is used for joint optimization of coding and modulation. The transmitted bits are processed by neural networks-code and modulate (NN-CoMo) to obtain modulated symbols, which are then sent to the T-NN for processing after IFFT and other processing. Correspondingly, after obtaining the signal processed by T-NN, the receiving end performs IFFT processing on the signal and then processes the transformed signal through neural networks-decode and demodulate (NN-DeCoMo).In Figure 5(c), a neural network is used to optimize the reference signal. The transmitter generates a reference signal based on the neural network, and then sends it to the T-NN for processing after IFFT and other processing. Correspondingly, after receiving the T-NN-processed signal, the receiver performs IFFT processing on the signal and then uses the neural network to perform channel estimation on the transformed signal.

[0151] In a neural network-based transceiver, the intelligent air interface can optimize the transceiver signal through data-driven optimization. Due to differences in data distribution in different scenarios, performance may vary. To ensure communication performance, it may be necessary to switch different neural network models, resulting in switching of the intelligent air interface or fallback from the intelligent air interface to the traditional air interface. On the other hand, it may also fall back from the intelligent air interface to the traditional air interface due to changes in the device's computing or storage capabilities.

[0152] Please refer to Figure 6, which is a flow chart of a traditional data transmission process provided by an embodiment of the present application. The details are as follows:

[0153] S601: The first device and the second device perform data transmission via the smart air interface / traditional air interface.

[0154] S602: The second device sends handover indication information to the first device, where the handover indication information is used to indicate air interface handover.

[0155] S603: The first device receives switching instruction information.

[0156] After the first device receives the switching instruction information from the second device, the first device performs air interface switching, for example, the first device switches from the smart air interface to the traditional air interface, or the first device switches from the traditional air interface to the smart air interface.

[0157] S604: The first device and the second device perform data transmission via the traditional air interface / intelligent air interface.

[0158] As shown in FIG6 , before and after the air interface switching, transmission resources may be wasted and transmission efficiency may be reduced. To solve the above problems, the embodiment of the present application proposes the following solution.

[0159] Please refer to FIG. 7 , which shows a communication method provided by an embodiment of the present application. The method includes but is not limited to the following steps:

[0160] Step S701: The first device obtains instruction information.

[0161] Among them, the first device can be a terminal device or a network device. In one example, when the first device is a terminal device, the first device obtaining the indication information can be understood as the first device receiving the indication information from the second device, and the second device can be a network device. Optionally, before the first device receives the indication information from the second device, the first device sends a request message to the second device, and the request message is used to request enablement. Correspondingly, after the second device receives the request message, it sends the indication information to the first device. In another example, when the first device is a network device, the first device obtaining the indication information can be understood as the first device determining the indication information, and the indication information is determined by the network device. In another example, when the first device is a first terminal device and the second device is a second terminal device, the first device obtaining the indication information can be understood as the first device obtaining the indication information from the network device, and the indication information is determined by the network device.

[0162] The indication information is used to indicate an enabling mode of the first air interface, and the enabling mode may include one or more of the following: a non-retransmission enabling mode, a retransmission enabling mode, or a hybrid automatic repeat request (HARQ) enabling mode. The first air interface may be a smart air interface.

[0163] The non-retransmission enable mode, the retransmission enable mode, and the HARQ enable mode are determined by one or more of the following, including: real-time performance of air interface transmission, statistical performance of air interface transmission, or artificial intelligence (AI) resource status. The non-retransmission enable mode may be determined by a network device or a terminal device based on the statistical performance of air interface transmission or the AI ​​resource status. The statistical performance of air interface transmission may refer to decoding performance within a period of time or transmission rate within a period of time. The period of time may be specified by a protocol, configured by a network device, or reported by a terminal device, and is not limited in this embodiment of the present application. The AI ​​resource status may include computing resources or cache resources. In one example, when the decoding performance within a period of time reaches threshold 1, the transmission rate within a period of time reaches threshold 2, the computing resources reach threshold 3, and the cache resources reach threshold 4, the enabling mode of the first air interface is determined to be the non-retransmission enable mode. The retransmission enable mode may be determined by a network device or a terminal device based on the real-time performance of air interface transmission or the AI ​​resource status. The real-time performance of air interface transmission may refer to real-time decoding performance or real-time transmission rate. Among them, the HARQ enabling mode can be determined by the network device or terminal device based on the real-time performance of air interface transmission or the AI ​​resource status.

[0164] The indication information may be carried in physical layer downlink control information (DCI), a MAC control element (CE), or RRC signaling. The indication information may also include one or more of the following: HARQ version information, new data indication (NDI) information, air interface type information, or transmission configuration information. It should be noted that the HARQ version information, NDI information, air interface type information, or transmission configuration information may also be carried in other messages or information, which is not limited in the embodiments of the present application. The HARQ version information may include redundancy version (RV) information. The NDI information may include new transmission or retransmission indication information. The air interface type information may include a first air interface or a second air interface, where the first air interface or the second air interface is the configuration of the enabled air interface, which may also be understood as the air interface selected for air interface transmission after being enabled being the first air interface or the second air interface. The first air interface may be a smart air interface, and the second air interface may be a traditional air interface. The transmission configuration information may include time-frequency resource information or modulation and coding scheme (MCS) information. It can also include offset indication information compared to the transmission configuration information before enabling, that is, the transmission configuration information can be determined by the offset indication information and the transmission configuration information before enabling, wherein the transmission configuration information can be the transmission configuration information after enabling, and compared with the transmission configuration information before enabling, the transmission configuration information is new transmission configuration information.

[0165] For example, the indication information is carried in the DCI, and the DCI may be a DCI scrambled by a specific radio network temporary identity (RNTI). One DCI corresponds to one HARQ process, and can also be understood as indicating one DCI separately for each HARQ process. The indication information is carried in the DCI, and the indication information may include HARQ version information or NDI information, wherein the HARQ version information or NDI information may implicitly indicate the enabling mode of the first air interface. The indication information is carried in the DCI, and the indication information may also include air interface category information.

[0166] For example, the indication information is carried in a MACCE, and the MACCE includes a specific logical channel identification (LCID) field. Please refer to Figure 8, which is a signaling format of a MACCE provided in an embodiment of the present application. The MACCE may include air interface category information or transmission configuration information. The air interface corresponding to the air interface category information is composed of at least one processing module, and the air interface category information is independently indicated by each processing module in the at least one processing module, or is jointly indicated by the at least one processing module. The processing module may refer to a specific or multiple modules in the sending or receiving processing of a neural network-based transceiver, for example, it can be used to optimize the channel coding, modulation, waveform, pilot and other modules in the transceiver signal processing. The air interface category information can be indicated by a bitmap or an index, for example, 1 bit can be used to indicate an intelligent air interface or a traditional air interface. In one example, the air interface category information is independently indicated by each module in at least one processing module, and the air interface category information is indicated by a bitmap. The air interface category information is 110, and the "1" in the first position indicates that the air interface selected for air interface transmission in the channel coding module is an intelligent air interface, that is, the air interface after enabling is an intelligent air interface. The "1" in the second position indicates that the air interface selected for air interface transmission in the modulation module is an intelligent air interface, that is, the air interface after enabling is an intelligent air interface. The "0" in the third position indicates that the air interface selected for air interface transmission in the waveform module is a traditional air interface, that is, the air interface after enabling is a traditional air interface. In another example, the air interface category information is jointly indicated by the at least one processing module, and the air interface category information is indicated by an index. The air interface category information can be 0, 1, ..., 7, which respectively indicate the indexes of possible combinations of each module as an intelligent air interface or a traditional air interface. For example, when the air interface category information is 7, it indicates that at least one processing module, for example, 3 processing modules, respectively include a channel coding module, a modulation module, and a waveform module, wherein the channel coding module, the modulation module, and the waveform module jointly indicate that the air interface selected for air interface transmission is an intelligent air interface, that is, the air interface after being enabled is an intelligent air interface; when the air interface category information is 6, it indicates that at least one processing module, for example, 3 processing modules, respectively include a channel coding module, a modulation module, and a waveform module, wherein the channel coding module and the modulation module jointly indicate that the air interface selected for air interface transmission is an intelligent air interface, and the waveform module jointly indicates that the air interface selected for air interface transmission is a traditional air interface; and so on, when the air interface category information is 0, it indicates that at least one processing module, for example, 3 processing modules, respectively include a channel coding module, a modulation module, and a waveform module, wherein the channel coding module, the modulation module, and the waveform module jointly indicate that the air interface selected for air interface transmission is a traditional air interface, that is, the air interface after being enabled is a traditional air interface.

[0167] Step S702: The first device sends first information to the second device according to the instruction information.

[0168] The first device sends the first information to the second device according to the instruction information, which is divided into the following three situations:

[0169] Case 1: The enabling mode includes a non-retransmission enabling mode, and the first information includes new data information transmitted after enabling. That is, the enabling mode of the first air interface indicated by the indication information is a retransmission enabling mode. The first device sends the first information to the second device according to the indication information, and the first information includes the new data information transmitted after enabling. Optionally, the new data information transmitted after enabling may include RV information. Optionally, the new data information transmitted after enabling can be understood as re-encoded data information compared to the data information transmitted before enabling.

[0170] Optionally, enabling can be understood as a change in the air interface state or an air interface switch, such as switching from an intelligent air interface to a traditional air interface, from a traditional air interface to an intelligent air interface, or from an intelligent air interface to an intelligent air interface. Enabling includes one or more of the following: activation of a first air interface, deactivation of the first air interface, switching from the first air interface to a second air interface, or fallback of the first air interface to the second air interface, where the first air interface is different from the second air interface. In one example, the first air interface may be a smart air interface, and the second air interface may be a traditional air interface; in another example, the first air interface may be a traditional air interface, and the second air interface may be a smart air interface; in another example, the first air interface may be a smart air interface in processing module 1, and the second air interface may be a traditional air interface in processing module 1; in another example, the first air interface may be a first smart air interface, and the second air interface may be a second smart air interface, and the first smart air interface and the second smart air interface are different. Case 1: The first smart air interface is composed of at least one processing module, and the second smart air interface is composed of at least one processing module, wherein the number of processing modules of the first smart air interface and the second smart air interface is different, for example, the first smart air interface is composed of 2 processing modules, and the second smart air interface is composed of 3 processing modules; Case 2: The number of processing modules of the first smart air interface and the second smart air interface is the same, but the parameters of at least one processing module are different. For the relevant explanation of the processing modules, please refer to the explanation of the processing modules in step S601, which will not be repeated here. In one example, assuming that the air interface transmission before enabling is an intelligent air interface, enabling includes switching from the first air interface to the second air interface, for example, switching from the intelligent air interface to the traditional air interface, then the enabling mode includes a non-retransmission enabling mode, and the first information includes new data information transmitted after enabling. It can be understood that the enabling mode includes a non-retransmission enabling mode, and the first information includes new data information transmitted after switching from the intelligent air interface to the traditional air interface. The first device can send new data information to the second device through the traditional air interface according to the indication information.

[0171] It should be noted that the enabling proposed in the embodiment of the present application can also be called air interface intelligent enabling, which is not limited in the embodiment of the present application.

[0172] Optionally, the first device may send the first information to the second device based on the indication information and the transmission configuration information. The transmission configuration information may be understood as the transmission configuration information after being enabled, and compared to the transmission configuration information before being enabled, the transmission configuration information is new transmission configuration information. Accordingly, the second device may receive the first information from the first device based on the indication information and the transmission configuration information, and optionally, may decode the first information using the transmission configuration information. Optionally, the transmission configuration information may be reconfigured by the network device before obtaining the indication information or before the first device sends the first information.

[0173] Optionally, before the first device sends the first information to the second device according to the indication information, the first device resets the HARQ process state and the first device may further clear the transmission buffer. Correspondingly, before the second device receives the first information from the first device according to the indication information, the second device resets the HARQ process state and the second device may further clear the reception buffer.

[0174] In an example, please refer to Figure 9, which is a schematic diagram of air interface transmission before and after enabling provided by an embodiment of the present application. Assume that before enabling, the first device transmits RV0 and RV1 through the intelligent air interface, where RV0 represents redundant version information 0, and RV1 represents redundant version information 1. The second device fails to decode RV1 successfully. At this time, the first device obtains the indication information, and the enabling mode indicated by the indication information includes the non-retransmission enabling mode. Accordingly, the first device enables, and the enabling includes switching the first air interface to the second air interface, for example, switching from the intelligent air interface to the traditional air interface, and then the first device sends the first information to the second device through the traditional air interface according to the indication information. The first information is the re-encoded RV0, and the re-encoded RV0 can be understood as the new data information transmitted after enabling; if the decoding of the re-encoded RV0 fails, the first device may send the re-encoded RV1 through the traditional air interface.

[0175] In the above method, the air interface transmission mode is configured by enabling the mode including the non-retransmission enabling mode, thereby improving the intelligent flexibility of the air interface, and by indicating the mechanism of air interface transmission after enabling, it is possible to avoid resource waste and improve transmission efficiency.

[0176] Case 2: The enabling mode includes a retransmission enabling mode, and the first information includes data information transmitted before enabling, that is, the enabling mode indicated by the indication information is a retransmission enabling mode. The first device sends the first information to the second device according to the indication information, and the first information includes data information transmitted before enabling. Optionally, the data information transmitted before enabling can be RV information. For the relevant description of enabling, please refer to the explanation of enabling in Case 1, and will not be repeated here. In an example, assuming that the air interface transmission before enabling is an intelligent air interface, enabling includes switching the first air interface to the second air interface, for example, switching from the intelligent air interface to the traditional air interface, then the enabling mode includes a retransmission enabling mode, and the first information includes data information transmitted before enabling. It can be understood that the enabling mode includes a retransmission enabling mode, and the first information includes data information transmitted before enabling that is transmitted after switching from the intelligent air interface to the traditional air interface. The first device can send the data information transmitted before enabling to the second device through the traditional air interface according to the indication information. Optionally, the data information transmitted before enabling can be understood as data information that is not re-encoded after enabling.

[0177] Optionally, before the first device sends the first information to the second device according to the indication information, the first device freezes the HARQ process state, and the first device may also maintain the sending cache. Correspondingly, before the second device receives the first information from the first device according to the indication information, the second device freezes the HARQ process state, and the second device may also maintain the receiving cache.

[0178] Optionally, the first device may send the first information to the second device based on the indication information and the transmission configuration information. The transmission configuration information may refer to the transmission configuration information before enabling, that is, the first device reuses the transmission configuration information before enabling for air interface transmission; or it may refer to the transmission configuration information after enabling. Compared with the transmission configuration information before enabling, the transmission configuration information is new transmission configuration information. Accordingly, the second device combines and decodes the first information and the second information. The second information is the data information received before enabling. The data information received before enabling may refer to data information that was successfully received but not decoded before enabling. Optionally, after combining and decoding the first information and the second information, the second device may resend the decoding result to the first device based on the frozen HARQ process state. The decoding result includes an acknowledgement (ACK) or a negative acknowledgement (NACK).

[0179] In one example, please refer to Figure 10, which is another schematic diagram of air interface transmission before and after enablement provided by an embodiment of the present application. Assume that before enablement, the first device transmits RV0 and RV1 through the intelligent air interface, where RV0 represents redundant version information 0 and RV1 represents redundant version information 1. The second device fails to successfully decode RV1. At this time, the first device obtains indication information, and the enablement mode indicated by the indication information includes a retransmission enablement mode. Accordingly, the first device enables, and the enabling includes switching the first air interface to the second air interface, for example, switching from the intelligent air interface to the traditional air interface. Then, the first device sends the first information to the second device through the traditional air interface according to the indication information. The first information is RV1. RV1 can be understood as data information transmitted before enablement. Optionally, the second device can receive the first information, i.e., RV1, through the traditional air interface according to the indication information, and then combine and decode the first information, i.e., RV1, and the second information, i.e., RV0. The second information, i.e., RV0, can be understood as data information received before enablement.

[0180] In the above method, the air interface transmission mode is configured by including a retransmission enabling mode in the enabling mode, thereby improving the intelligent flexibility of the air interface, and the data before and after enabling can be repeatedly transmitted by including the first information in the data information transmitted before enabling, thereby improving the efficiency of data transmission, and by indicating the mechanism of air interface transmission after enabling, it is possible to avoid resource waste and improve transmission efficiency.

[0181] Case 3: The enabling mode includes an HARQ enabling mode, and the first information is data information related to the data information transmitted before enabling. That is, the enabling mode indicated by the indication information is the HARQ enabling mode. The first device sends the first information to the second device according to the indication information. The first information is data information related to the data information transmitted before enabling. Optionally, the data information related to the data information transmitted before enabling can be RV information. For the relevant description of enabling, please refer to the explanation of enabling in Case 1 and will not be repeated here. In one example, assuming that the air interface transmission before enabling is a smart air interface, enabling includes switching from the first air interface to the second air interface, for example, switching from the smart air interface to the traditional air interface, then the enabling mode includes an HARQ enabling mode, and the first information is data information related to the data information transmitted before enabling. It can be understood that the enabling mode includes the HARQ enabling mode, and the first information is data information related to the data information transmitted before enabling that is transmitted after switching from the smart air interface to the traditional air interface. The first device can send data information related to the data information transmitted before enabling to the second device via the traditional air interface according to the indication information.

[0182] Optionally, the relevant data information is first redundant version information, and the data information transmitted before enabling is second redundant version information, wherein the first redundant version information and the second redundant version information are different, and the first redundant version information and the second redundant version information belong to the same encoding codeword. The first redundant version information and the second redundant version information belonging to the same encoding codeword can be understood as that the channel encoder encodes the information bits to obtain coded bit data, and the coded bit data includes the first redundant version information and the second redundant version information. Optionally, the first redundant version information and the second redundant version information can be different coded bits in the same buffer.

[0183] It should be noted that in the embodiments of the present application, the redundant version information can refer to either a redundant version of the channel coding or a symbol. When the redundant version information refers to a redundant version of the channel coding, the intelligent air interface can be composed of channel coding and subsequent intelligent modulation, etc. The subsequent intelligent modulation can be understood as a neural network replacing the modulation module in the sending or receiving processing in a neural network-based transceiver. At this time, enabling can refer to the switching between intelligent modulation and traditional modulation, etc., while the channel coding remains unchanged before and after enabling. When the redundant version information refers to a symbol, for example, channel coding modulation is completed jointly by traditional methods or neural networks. At this time, enabling can refer to the switching of modules such as precoding after modulation, transmitting different symbols before and after switching, and merging and receiving them.

[0184] Optionally, before the first device sends the first information to the second device according to the indication information, the first device updates the HARQ process status, and the first device may also maintain the sending cache. Correspondingly, before the second device receives the first information from the first device according to the indication information, the second device updates the HARQ process status, and the second device may also maintain the receiving cache.

[0185] Optionally, the first device may send the first information to the second device based on the indication information and the transmission configuration information. The transmission configuration information may refer to the transmission configuration information before enabling or the transmission configuration information after enabling. For details, please refer to the relevant description of the transmission configuration information in Case 2, which will not be repeated here. Accordingly, the second device combines and decodes the first information and the second information, and the second information is the data information received before enabling. The data information received before enabling may refer to data information that was successfully received but not decoded before enabling. Optionally, after combining and decoding the first information and the second information, the second device may resend the decoding result to the first device based on the updated HARQ process status, and the decoding result includes ACK or NACK.

[0186] In an example, please refer to Figure 11, which is another schematic diagram of air interface transmission before and after enabling provided by an embodiment of the present application. It is assumed that the encoding end performs channel coding to obtain coded bit data, and caches the coded bit data in a buffer. Each transmission only transmits a portion of the coded bit data, which is represented by redundant version information. For example, the bit data is 30 bits, RV0 is the first 10 bits, RV1 is the middle 10 bits, and RV2 is the last 10 bits. Before enabling, the first device transmits RV0 and RV1 through the intelligent air interface, and the second device fails to decode successfully. At this time, the first device obtains indication information, and the enabling mode indicated by the indication information includes the HARQ enabling mode. Accordingly, the first device enables, and the enabling includes switching the first air interface to the second air interface, for example, switching from the intelligent air interface to the traditional air interface. Then, the first device sends first information to the second device through the traditional air interface according to the indication information. The first information is RV2. RV2 can be understood as data information related to the data information transmitted before enabling. Optionally, the second device can receive the first information, i.e., RV2, according to the indication information through the intelligent air interface, and then merge and decode the first information, i.e., RV2, and the second information, i.e., RV1 and RV0, wherein the second information, i.e., RV1 and RV0, can be understood as data information received before enabling.

[0187] Step S703: The second device receives the first information according to the instruction information.

[0188] In the above method, the air interface transmission mode is configured by including the HARQ enable mode in the enable mode, thereby improving the intelligent flexibility of the air interface. Moreover, by indicating the mechanism of air interface transmission after enabling, resource waste can be avoided and transmission efficiency can be improved. Step S703: The second device receives the first information from the first device according to the indication information.

[0189] In the method described in Figure 7, the first device obtains indication information and sends the first information to the second device according to the indication information. This allows the first device to send different contents of the first information according to the different contents included in the indication information, thereby determining the transmission mechanism of the air interface, avoiding resource waste, and improving transmission efficiency.

The RF circuit then performs RF processing on the baseband signal and transmits the RF signal to the outside in the form of electromagnetic waves through the antenna. When data is sent to the terminal device, the RF circuit receives the RF signal through the antenna. The RF circuit converts the RF signal into a baseband signal and outputs the baseband signal to the processor. The processor converts the baseband signal into data and processes the data.
