Description

Measurement methods and related devices Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a measurement method and related devices. Background Art

[0002] To meet the vision of intelligent and inclusive future, intelligence will further evolve at the wireless network architecture level. Artificial intelligence (AI) will be further integrated with wireless networks, enabling endogenous network intelligence. This will also include intelligent terminal devices. For example, terminal types will be diversified, and terminal device connections will be more flexible and intelligent. Terminal devices will also possess certain AI capabilities. In addition to providing traditional communication and connectivity services, the network will also provide computing and AI services to better support inclusive, real-time, and highly secure AI services.

[0003] Currently, in wireless communications, there are proposals to use neural networks to optimize physical layer modules such as channel coding, modulation, and waveform processing. This could potentially change the existing physical layer processing module structure, such as joint channel coding and modulation, and pre-distortion processing.

[0123] Embodiments of the present application provide a measurement method and related apparatus, wherein a first device can measure one or more first measurement signals based on one or more first air interface configurations to obtain one or more first measurement results. The first device transmits the one or more first measurement results to a second device. The one or more first measurement results are thereby used to characterize the performance of a first type of air interface configured by the one or more first air interface configurations. This facilitates the second device in selecting an appropriate first air interface configuration for the first device, thereby enabling establishment of a first type of air interface configured by the first air interface configuration between the first device and the second device.

[0124] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described 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 creative efforts are within the scope of protection of this application.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] 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.

[0131] 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.

[0132] 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.

[0133] The technical solution of the present application can be applied to cellular communication systems related to the 3rd Generation Partnership Project (3GPP). For example, the fourth generation (4G) communication system, the fifth generation (5G) communication system, and the communication system after the fifth generation communication system. For example, the sixth generation communication system. For example, the fourth generation communication system may include a long term evolution (LTE) communication system. The fifth generation communication system may include a new radio (NR) communication system. The technical solution of the present application can also be applied to wireless fidelity (WiFi) systems, communication systems that support the integration of multiple wireless technologies, device-to-device (D2D) systems, vehicle to everything (V2X) communication systems, or satellite communication systems, etc. The wireless communication systems involved in this application also include but are not limited to: narrowband Internet of Things (NB-IoT) system, global system for mobile communications (GSM), enhanced data rate for GSM evolution (EDGE), wideband code division multiple access (WCDMA), code division multiple access 2000 (CDMA2000), or time division-synchronization code division multiple access (TD-SCDMA).

[0134] The communication system to which the technical solution of the present application is applicable includes a first device and a second device. Optionally, the communication system further includes more devices, and the second device and the more devices can execute a technical solution similar to that of the present application.

[0136] Optionally, the second device is a network device or a terminal device; or the first device is a chip, chip system, or processor in the network device or the terminal device; or the first device is a logic module or software that implements part or all of the functions of the network device; or the second device is a logic module or software that implements part or all of the functions of the terminal device.

[0137] For example, the first device is a terminal device and the second device is a network device; or the first device is a network device and the second device is a terminal device; or the first device is a first terminal device and the second device is a second terminal device. Optionally, the network device is an access network device or a core network device. The following mainly uses the network device as an access network device as an example to describe the technical solution of this application.

[0138] Figure 1 is a schematic diagram of a communication system according to an embodiment of the present application. As shown in Figure 1, the first device is a terminal device 101, and the second device is a base station 103. Alternatively, the first device is a base station 103, and the second device is a terminal device 101. The technical solution of the present application can be implemented between the terminal device 101 and the base station 103. Alternatively, the first device is a terminal device 101, and the second device is a terminal device 102. The technical solution of the present application can be implemented between the terminal device 101 and the terminal device 102. As shown in Figure 1, the communication system includes an independent AI network element 104, or AI modules can exist in the base station and the terminal device respectively, so as to provide AI services.

[0139] The following introduces the terminal equipment and network equipment involved in this application.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] 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).

[0145] 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.

[0146] Optionally, for network elements in the ORAN system, each network element may implement the protocol layer functions shown in Table 1 below.

[0147] Table 1

[0148] It should be noted that the network device can be one or more network elements shown in Table 1 above, and this application does not make any specific limitations.

[0149] 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.

[0150] 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.

[0151] 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.).

[0152] 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.

[0153] 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.

[0154] 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.

[0155] 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.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] Figure 2A is another schematic diagram of a communication system according to an embodiment of the present application. As shown in Figure 2A, 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 the sake of 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.

[0160] 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.

[0161] 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.

[0162] It should be noted that the access network node shown in Figure 2A can be used as a whole, or the access network node shown in Figure 2A can adopt a CU and DU separated architecture. Figure 2B shows a schematic diagram of a communication system in which the access network node is used as a whole and the access network node is connected to a terminal device. Figure 2C shows a schematic diagram of a communication system in which the access network node adopts a CU and DU separated architecture.

[0163] Currently, in wireless communications, the use of neural networks to optimize physical layer modules such as channel coding, modulation, and waveform processing is being proposed. This could potentially change the existing physical layer processing module structure, such as joint channel coding and modulation, and pre-distortion processing. It could also alter current signal processing methods, such as pilotless modulation. Therefore, AI-based air interface systems will coexist with traditional air interface systems in future networks. Therefore, selecting the appropriate air interface system for terminal devices is a question worth considering.

[0164] Signals are transmitted between network devices and terminal devices over the air interface. For a transmitting device, as shown in Figure 3, at the physical layer, air interface processing may include at least one of the following: channel coding, symbol modulation, resource mapping, waveform modulation, and RF processing. Specifically, the transmitting device may perform channel coding using a channel coding module, QAM modulation using a symbol modulation module, resource mapping using a resource mapping module, waveform processing using a waveform modulation module, and transmit signals using an RF processing module.

[0165] For a receiving device, as shown in Figure 4, at the physical layer, air interface processing may include at least one of the following: channel decoding, symbol demodulation, resource demapping, waveform demodulation, or RF processing. Specifically, the receiving device may receive signals via an RF processing module, perform waveform demodulation via a waveform demodulation module, perform resource demapping via a resource demapping module, perform symbol demodulation via a symbol demodulation module, and perform channel decoding via a channel decoding module.

[0166] Of course, the above only describes the air interface processing process from the physical layer. In fact, air interface processing can also include some processing at the MAC layer and / or some processing at the PDCP layer, such as scheduler configuration at the MAC layer and encryption and decryption configuration at the PDCP layer.

[0167] Figures 3 and 4 above only illustrate the air interface processing process from the physical layer. In fact, the air interface processing process at the physical layer can also be implemented in other ways, and Figures 3 and 4 above do not limit this application. For example, in the example shown in Figure 3 above, some functional modules can be merged, or some functional modules can be further subdivided into functions, which is not limited in this application.

The first terminal device and the second terminal device establish the second type of air interface through a sidelink discovery process. Alternatively, the first terminal device and the second terminal device establish the second type of air interface based on scheduling by the network device.

[0188] In this implementation, the first device and the second device can complete parameter configuration, signaling transmission, etc. through the second type of air interface. Then, the first device and the second device perform the above step 501 again.

[0189] 502. The first device measures the one or more first measurement signals based on one or more first air interface configurations to obtain one or more first measurement results.

[0190] The one or more first measurement results are used to characterize performance of the first type of air interface configured by the one or more first air interface configurations.

[0191] The one or more first air interface configurations are used to configure one or more first type air interfaces. Optionally, one first air interface configuration is used to configure one first type air interface, and different first air interface configurations are used to configure different first type air interfaces.

[0192] Each first type of air interface configured for the one or more first air interface configurations includes one or more functional modules, at least one of the one or more functional modules being implemented based on AI.

[0199] Table 4

[0200] Optionally, the one or more first air interface configurations are pre-configured in the first device.

[0201] Optionally, the one or more first measurement signals include a first target measurement signal. The above step 502 specifically includes step 502a and step 502b.

[0202] 502a. The first device receives the first target measurement signal through the first type of air interface configured by the first air interface configuration corresponding to the first target measurement signal.

[0203] For example, the following describes, in conjunction with FIG4 , a possible implementation method for a first device to receive a first target measurement signal via a first type of air interface configured by a first air interface configuration corresponding to the first target measurement signal. As shown in FIG4 , the first type of air interface configured by the first air interface configuration corresponding to the first target measurement signal includes a channel decoding module, a symbol demodulation module, a resource demapping module, a waveform demodulation module, and a radio frequency processing module. The channel decoding module, the symbol demodulation module, the resource demapping module, the waveform demodulation module, and the radio frequency processing module are implemented by a neural network 2. The first device processes the first target measurement signal from the second device through radio frequency processing, waveform demodulation, resource demapping, symbol demodulation, and channel decoding via the neural network 2, thereby receiving the first target measurement signal.

[0204] 502b. The first device determines a first measurement result corresponding to the first target measurement signal according to the first target measurement signal received by the first device.

[0205] In one possible implementation, the first device determines the similarity between a first target measurement signal received by the first device and a first target measurement signal pre-agreed between the first device and the second device. That is, the first measurement signal corresponding to the first target measurement signal includes the first target measurement signal received by the first device and the similarity between the first target measurement signal pre-agreed between the first device and the second device. For example, the first device calculates the correlation coefficient between the first target measurement signal received by the first device and the first target measurement signal pre-agreed between the first device and the second device. This correlation coefficient is used to characterize the similarity between the first target measurement signal received by the first device and the first target measurement signal pre-agreed between the first device and the second device. For example, the data carried by the first target measurement signal received by the first device is alphab, and the data carried by the first target measurement signal pre-agreed between the first device and the second device is alpha. Therefore, it can be determined that the similarity between the first target measurement signal received by the first device and the first target measurement signal pre-agreed between the first device and the second device is 80%.

[0206] In another possible implementation, the first device determines a bit error rate of a data packet carried in a first target measurement signal received by the first device. That is, the first measurement result corresponding to the first target measurement signal includes the bit error rate of the data packet carried in the first target measurement signal received by the first device.

[0207] Optionally, the embodiment shown in FIG5 further includes step 501b.

[0208] 501b. The second device sends one or more first indication information to the first device. Correspondingly, the first device receives one or more first indication information from the second device.

[0209] The one or more first indication information corresponds to the one or more first measurement signals. Each first indication information is used to indicate the first air interface configuration corresponding to the first measurement signal corresponding to the first indication information. The first air interface configuration corresponding to the first measurement signal is used to measure the first measurement signal. For example, as shown in Table 4, the one or more first indication information may include four first indication information, namely first indication information 1 to first indication information 4. First indication information 1 is used to indicate that the first measurement signal 1 corresponds to the first air interface configuration 1. First indication information 2 is used to indicate that the first measurement signal 2 corresponds to the first air interface configuration 2. First indication information 2 is used to indicate that the first measurement signal 3 corresponds to the first air interface configuration 3. First indication information 4 is used to indicate that the first measurement signal 4 corresponds to the first air interface configuration 4. This enables the first device to measure the corresponding first measurement signal based on the corresponding first air interface configuration.

[0210] Optionally, there is no fixed order for executing step 501b and step 501. Step 501 may be executed first, followed by step 501b; or, step 501b may be executed first, followed by step 501; or, depending on the circumstances, both steps 501 and 501b may be executed simultaneously, which is not limited in this application. If the embodiment shown in FIG. 5 also includes step 501a, step 501b may be executed before step 501a.

[0211] Optionally, the one or more first indication information are carried in measurement control information.

[0212] Optionally, the measurement control information is carried in an RRC message. For example, the measurement control information is carried in an RRC reconfiguration message. In this implementation, optionally, the second device sends an RRC reconfiguration complete message to the first device.

[0213] Optionally, the second device may send the one or more first indication information to the first device via the first type air interface or the second type air interface currently used by the second device. Correspondingly, the first device may receive the one or more first indication information from the second device via the first type air interface or the second type air interface currently used by the first device.

[0214] 503. The first device sends one or more first measurement results to the second device. Correspondingly, the second device receives the one or more first measurement results from the first device.

[0215] Specifically, after the second device receives the one or more first measurement results, the second device can determine the performance of each first type air interface configured by the one or more first air interface configurations based on the one or more second measurement results. This facilitates the second device indicating the corresponding first air interface configuration to the first device, thereby facilitating the first device and the second device to establish the first type air interface configured by the first air interface configuration. The first device can receive data and / or signals sent by the second device via the first type air interface configured by the first air interface configuration.

[0216] Optionally, the second device may determine the performance of each first type air interface configured by the one or more second air interface configurations using the one or more first measurement results. The second device may select a corresponding second air interface configuration for the second device, and enable the second device to establish a first type air interface with the first device using the second air interface configuration. The second device may send data and / or signals to the first device via the first type air interface configured by the second air interface configuration.

[0217] In one possible implementation, the second device may indicate the second air interface configuration selected by the second device to the first device. The first device may also transmit data and / or signals to the second device via the first type air interface configured by the second air interface configuration. The second device may also receive data and / or signals transmitted by the first device via the first type air interface configured by the first air interface configuration selected for the first device.

[0218] Optionally, the first device may send the one or more first measurement results to the second device via the first type air interface or the second type air interface currently used by the second device. Correspondingly, the second device may receive the one or more first measurement results from the first device via the first type air interface or the second type air interface currently used by the second device.

[0219] In an embodiment of the present application, a first device receives one or more first measurement signals from a second device. Then, the first device measures the one or more first measurement signals based on one or more first air interface configurations to obtain one or more first measurement results. The one or more first measurement results are used to characterize the performance of the first type of air interface configured by the one or more first air interface configurations. The first device sends the one or more first measurement results to the second device. It can be seen that the first device can measure the one or more first measurement signals based on one or more first air interface configurations to obtain one or more first measurement results. The first device sends the one or more first measurement results to the second device. The performance of the first type of air interface configured by the one or more first air interface configurations is thereby characterized by the one or more first measurement results. This facilitates the second device to indicate the corresponding first air interface configuration to the first device, thereby facilitating the first device and the second device to establish the first type of air interface configured by the first air interface configuration.

[0220] It should be noted that the above is an introduction to the technical solution of the present application using the first device as a receiving device for measuring signals and the second device as a sending device for measuring signals as an example. In actual applications, when the first device serves as a sending device for measuring signals and the second device serves as a receiving device for measuring signals, the first device in the embodiment shown in FIG5 above can be replaced by the second device, and the second device can be replaced by the first device, thereby realizing the selection of a suitable first type of air interface for the first device to send data and / or signals to the second device. Optionally, it is also possible to realize the selection of a suitable first type of air interface for the second device to receive data and / or signals from the first device.

[0221] In the present application, optionally, each of the one or more first air interface configurations includes a set of parameters corresponding to each functional module in one or more functional modules. If the functional module is implemented based on AI, the functional module corresponds to a set of model parameters. For example, the functional module corresponds to a set of neural network parameters. If the functional module is implemented based on non-AI, the functional module corresponds to a set of related parameters, for example, the functional module corresponds to a set of traditional signal processing parameters. For example, the set of related parameters corresponding to the functional module includes at least one of the following: modulation mode, modulation order, or channel coding rate.

[0222] The following describes a process in which the second device indicates the first air interface configuration to the first device, thereby implementing a first type of air interface established between the first device and the second device, in conjunction with the implementation shown in FIG6 or the embodiment shown in FIG8 .

[0225] The second indication information is used to activate at least one first air interface configuration among the one or more first air interface configurations.

[0226] Optionally, the second indication information is carried in the MAC CE. For example, the one or more first air interface configurations include seven first air interface configurations, namely, first air interface configuration 1 to first air interface configuration 8. As shown in Figure 7, the second indication information is the byte Qct1 in the MAC CE, the first bit in the byte corresponds to the first air interface configuration 1, the second bit corresponds to the first air interface configuration 2, the third bit corresponds to the first air interface configuration 3, the fourth bit corresponds to the first air interface configuration 4, the fifth bit corresponds to the first air interface configuration 5, the sixth bit corresponds to the first air interface configuration 6, the seventh bit corresponds to the first air interface configuration 7, and the eighth bit corresponds to the first air interface configuration 8. The second device indicates whether to activate the one or more first air interface configurations through the value of each bit in the byte. For example, if the value of a bit in the byte is 1, it indicates that the first air interface configuration corresponding to the bit is activated; if the value of a bit in the byte is 0, it indicates that the first air interface configuration corresponding to the bit is not activated, that is, the first air interface configuration corresponding to the bit is in a candidate state. For example, if the values ​​of the first bit and the third bit in the byte are both 1 and the values ​​of the other bits are all 0, it means that the first air interface configuration 1 and the first air interface configuration 3 are activated, and the other first air interface configurations are in the candidate state.

[0227] Optionally, the second indication information is a bit sequence, where bits in the bit sequence correspond to one or more first air interface configurations, and values ​​of bits in the bit sequence are used to indicate whether to activate the first air interface configuration corresponding to the bit.

[0228] For example, a bit in the bit sequence corresponds to a first air interface configuration in one or more first air interface configurations, and different bits in the bit sequence correspond to different first air interface configurations. For example, when the value of a bit in the bit sequence is 0, it indicates that the first air interface configuration corresponding to the bit is in a candidate state; when the value of a bit in the bit sequence is 1, it indicates that the first air interface configuration corresponding to the bit is in an activated state; or, when the value of a bit in the bit sequence is 0, it indicates that the first air interface configuration corresponding to the bit is in an activated state; when the value of a bit in the bit sequence is 1, it indicates that the first air interface configuration corresponding to the bit is in a candidate state.

[0232] Optionally, at least one first air interface configuration includes a first air interface configuration 1. The first device establishes a first type of air interface with the second device through the first air interface configuration 1. As shown in Figure 4, the first air interface configuration 1 includes one or more functional modules, each of which is implemented based on AI. The one or more functional modules are implemented by a neural network 2. The first device can process data and / or signals from the second device through the neural network 2, thereby recovering the data and / or signals sent by the second device.

[0233] Optionally, the at least one first air interface configuration includes multiple first air interface configurations. The second indication information also includes priorities of the multiple first air interface configurations. Alternatively, the second device indicates the priorities of the multiple first air interface configurations to the first device through other information.

[0237] The second device generates a second measurement signal based on one or more second air interface configurations and sends the second measurement signal to the first device. For example, the second measurement signal corresponds to one of the one or more second air interface configurations. The second device generates the second measurement signal based on the second air interface configuration. That is, the second device processes the data or information to be transmitted based on one or more functional modules in the first type of air interface configured according to the second air interface configuration to obtain the second measurement signal. The second measurement signal is an air interface signal.

[0238] 604. The first apparatus measures a second measurement signal based on the first air interface configuration 2 in the candidate state indicated in the second indication information to obtain a second measurement result.

[0239] The second measurement result represents the performance of the first type of air interface configured by the first air interface configuration 2.

[0245] 605. The first device sends the second measurement result to the second device. Correspondingly, the second device receives the second measurement result from the first device.

[0246] Optionally, the second measurement result indicates that the performance of the first type of air interface configured by the first air interface configuration 2 is greater than or equal to a first threshold.

[0247] Specifically, if the second measurement result indicates that the performance of the first type of air interface configured by the first air interface configuration 2 is greater than or equal to the first threshold, the first device may send the second measurement result to the second device. It should be noted that if the second measurement result indicates that the performance of the first type of air interface configured by the first air interface configuration 2 is less than the first threshold, the first device may not send the second measurement result. The first device continues to communicate with the second device using the first type of air interface configured by the first air interface configuration 1.

[0248] Optionally, the first threshold can be determined in conjunction with the channel state. For example, the second measurement result includes the similarity between the recovered second measurement signal and a second measurement signal pre-agreed between the first and second devices. Alternatively, the second measurement result includes the bit error rate of the data packet carried by the recovered second measurement signal. For example, the first threshold can be 80% or 90%.

[0251] 606. The second device sends third indication information to the first device. Correspondingly, the first device receives the third indication information from the second device.

[0252] The third indication information is used to activate the first air interface configuration 2.

[0256] Step 607 is similar to the aforementioned step 602. For details, please refer to the relevant introduction of the aforementioned step 602, which will not be repeated here.

[0257] In the embodiment shown in FIG. 6 , the second device sends second indication information to the first device. This enables the second device to indicate at least one first air interface configuration to the first device. The first device then establishes a first-type air interface with the second device using first air interface configuration 1 of the at least one first air interface configuration. Furthermore, if the second device determines, based on the second measurement result reported by the first device, that first air interface configuration 2 has superior performance, the second device may reselect the first air interface configuration for the first device. This improves transmission performance between the first and second devices.

[0265] Optionally, the embodiment shown in FIG8 further includes step 803 to step 804. Steps 803 to 804 may be performed after step 802.

[0266] 803. The second device sends fourth indication information to the first device. Correspondingly, the first device receives the fourth indication information from the second device.

[0267] Among them, the fourth indication information is used to indicate a first air interface configuration among the first air interface configurations activated in the second indication information; or, the fourth indication information is used to instruct the first device to use the second type of air interface to establish a connection with the second device; or, the fourth indication information is used to instruct the first device to reselect a first air interface configuration from the first air interface configurations activated in the second indication information.

[0268] Optionally, the second device sends the fourth indication information to the first device via the first type air interface. Correspondingly, the first device receives the fourth indication information from the second device via the first type air interface configured by the first air interface configuration 1.

[0269] Optionally, the second device sends fourth indication information to the first device via the second type of air interface, and correspondingly, the first device receives the fourth indication information from the second device via the second type of air interface.

[0270] Optionally, when the performance of the first type of air interface configured by the first air interface configuration 1 is less than a first threshold, the second device sends fourth indication information to the first device.

[0271] Optionally, the fourth indication information is carried in the first DCI.

[0272] Optionally, the fourth indication information is the first field in the first DCI. The value of the first field is used to indicate the corresponding first air interface configuration, or to instruct the first device to fall back to using the second type of air interface to establish a connection with the second device, or to instruct the first device to reselect a first air interface configuration from the first air interface configuration activated in the second indication information. For example, the first field is the air interface indicator field in the first DCI.

[0273] The following describes two possible indication methods for the first field. This application is still applicable to other indication methods and does not limit them specifically.

[0274] Implementation method 1: The at least one first air interface configuration activated by the second indication information includes the first air interface configuration 2, the first air interface configuration 3, and the first air interface configuration 4. The length of the first field is 2 bits. When the value of the first field is 00, it indicates that the first device falls back to using the second type of air interface to establish a connection with the second device. When the value of the first field is 01, it indicates the first air interface configuration 2. When the value of the first field is 10, it indicates the first air interface configuration 3. When the value of the first field is 11, it indicates the first air interface configuration 4.

[0275] It should be noted that the various values ​​and indicated meanings of the above-mentioned first field are possible examples and do not limit the indication method of the first field. This application does not make any specific limitations.

[0276] Implementation method 2: The length of the first field is 1 bit. The value of the first field is used to instruct the first device to reselect a first air interface configuration from the first air interface configuration activated in the second indication information. For example, the value of the first field is 1, indicating that the first device reselects a first air interface configuration from the first air interface configuration activated in the second indication information. Alternatively, the value of the first field is 0, indicating that the first device reselects a first air interface configuration from the first air interface configuration activated in the second indication information. Alternatively, the value of the first field is opposite to the value of the field for indicating the reselection of the first air interface configuration received by the first device before the first DCI, indicating that a first air interface configuration is reselected from the first air interface configuration activated in the second indication information. For example, if the value of the field for indicating the reselection of the first air interface configuration received by the first device before the first DCI is 1, and the value of the first field is 0, then the first field indicates that a first air interface configuration is reselected from the first air interface configuration activated in the second indication information.

[0277] Optionally, the first DCI also includes a time / frequency domain resource assignment field, which is used to indicate the time / frequency resource position occupied by the first type of air interface indicated by the fourth indication information. For example, the length of the time / frequency domain resource assignment field is X bits. X is an integer greater than or equal to 1. For example, X is 1, 2, 3 or 4. Optionally, the time / frequency domain resource assignment field can directly indicate the time / frequency resource position occupied by the first type of air interface indicated by the fourth indication information. Alternatively, the time / frequency domain resource assignment field can indicate the offset of the time / frequency resource position occupied by the first type of air interface indicated by the fourth indication information relative to the time / frequency resource position occupied by the first type of air interface currently adopted by the first device.

[0278] Optionally, the first DCI further includes a switching timing offset field, where the switching timing offset field is used to indicate the effective time of the first type of air interface indicated by the fourth indication information. For example, the length of the switching timing offset field is Y bits, where Y is an integer greater than or equal to 1. For example, Y is 1, 2, or 3.

[0279] Optionally, two possible triggering methods for the first device to detect the first DCI are described below. This application is still applicable to other triggering methods, and the following implementation methods do not limit this application.

[0280] The triggering mode 1 is described below in conjunction with step 803a. Optionally, the embodiment shown in FIG8 further includes step 803a, which can be performed before step 803.

[0281] 803a. When the performance of the first type of air interface configured by the first air interface configuration 1 is less than a first threshold, the first device detects a first DCI.

[0282] In this implementation, upon detecting that the performance of the first type of air interface configured by the first air interface configuration 1 is less than a first threshold, the first device detects the first DCI, thereby reducing DCI detection power consumption of the first device.

[0283] The following describes triggering mode 2 in conjunction with step 803b and step 803a. Optionally, the embodiment shown in FIG8 further includes step 803b and step 803a. Step 803b and step 803a can be performed before step 803.

[0284] 803b: The second device sends a trigger signal to the first device. The trigger signal is used to trigger the first device to detect the first DCI. Correspondingly, the first device receives the trigger signal from the second device.

[0285] Optionally, the second device sends a trigger signal to the first device via the first type air interface. Correspondingly, the first device receives the trigger signal from the second device via the first type air interface configured by the first air interface configuration 1.

[0286] Optionally, the second device sends a trigger signal to the first device via the second type of air interface. Correspondingly, the first device receives the trigger signal from the second device via the second type of air interface.

[0287] 803a. The first device detects a first DCI.

[0288] In this implementation, after the first device receives the trigger signal, the first device detects the first DCI, thereby reducing the DCI detection power consumption of the first device.

[0289] 804. The first device establishes a first type of air interface with the second device through the first air interface configuration indicated by the fourth indication information, or the first device establishes a second type of air interface with the second device, or the first device establishes a first type of air interface with the second device through the first air interface configuration reselected by the first device.

[0290] For example, the fourth indication information indicates the first air interface configuration, and the first device establishes the first type of air interface with the second device through the first air interface configuration. This implementation process is similar to the aforementioned step 602. For details, please refer to the relevant introduction of the aforementioned step 602, which will not be repeated here.

[0291] For another example, the fourth indication information instructs the first device to fall back to using the second type of air interface to establish a connection with the second device. The first device establishes the second type of air interface with the second device.

[0292] For another example, the fourth indication information instructs the first device to reselect a first air interface configuration from the first air interface configurations activated in the second indication information. The first device reselects a first air interface configuration from the first air interface configurations activated in the second indication information, and establishes a first type of air interface with the second device using the first air interface configuration. This implementation process is similar to the aforementioned step 602. For details, please refer to the relevant description of the aforementioned step 602 and will not be repeated here.

[0293] In the embodiment shown in FIG. 8 , the second device sends second indication information to the first device. This enables the second device to indicate at least one first air interface configuration to the first device. The first device then establishes a first-type air interface with the second device using first air interface configuration 1 of the at least one first air interface configuration. Furthermore, when the performance of the first-type air interface configured by first air interface configuration 1 is less than a first threshold, the second device may reselect the first air interface configuration for the first device using fourth indication information. This improves transmission performance between the first and second devices.

[0294] In the present application, optionally, each first type of air interface configured by the one or more first air interface configurations includes one or more functional modules. The one or more first air interface configurations include one or more sets of model parameters corresponding to each functional module in the one or more functional modules implemented based on AI. For example, the one or more sets of model parameters corresponding to each functional module include one or more sets of neural network parameters corresponding to each functional module. Optionally, the one or more first air interface configurations also include one or more sets of related parameters corresponding to each functional module in the one or more functional modules implemented based on non-AI. For example, the one or more sets of related parameters corresponding to each functional module include one or more sets of traditional signal processing parameters corresponding to each functional module. For example, a set of related parameters corresponding to each functional module includes at least one of the following: modulation mode, modulation order, or channel coding rate.

[0295] The following describes a process in which the second device indicates to the first device whether each of the one or more functional modules is implemented based on AI and the parameters used by each functional module in conjunction with the embodiment shown in FIG9 .

[0296] FIG9 is a schematic diagram of another embodiment of the measurement method of the present application. Referring to FIG9 , the method includes:

[0297] 901. The second device sends fifth indication information and / or sixth indication information to the first device. Correspondingly, the first device receives the fifth indication information and / or sixth indication information from the second device.

[0298] The fifth indication information is used to indicate whether each of the one or more functional modules is implemented based on AI. The sixth indication information is used to indicate the model parameters used by the functional modules implemented based on AI in the one or more functional modules.

[0299] Each Type 1 air interface includes one or more functional modules, each of which can be implemented based on AI or non-AI. Therefore, the second device can flexibly indicate whether each functional module is implemented based on AI through step 901. This allows all functional modules in the Type 1 air interface to be implemented based on AI, or some functional modules in the Type 1 air interface to be implemented based on non-AI.

[0300] Optionally, the second device sends the fifth indication information and / or the sixth indication information to the first device via the second type of air interface, and accordingly, the first device receives the fifth indication information and / or the sixth indication information from the second device via the second type of air interface. Alternatively, the second device sends the fifth indication information and / or the sixth indication information to the first device via the first type of air interface currently used by the second device, and accordingly, the first device receives the fifth indication information and / or the sixth indication information from the second device via the second type of air interface currently used by the first device.

[0301] Optionally, the fifth indication information and the sixth indication information may be sent separately or simultaneously, which is not limited in this application.

[0302] Optionally, the fifth indication information and the sixth indication information are carried in the second DCI.

[0303] Optionally, the fifth indication information is the first field in the second DCI. Several possible implementations of the first field are described below. This application is still applicable to other implementations, and this application does not limit them specifically.

[0304] Implementation 1: The length of the first field is equal to the number of functional modules in the one or more functional modules, M. One bit in the first field corresponds to one functional module, and the value of the bit is used to indicate whether the functional module corresponding to the bit is implemented based on AI.

[0305] For example, the first field is the Activation field of the second DCI, and the length of the Activation field is 5 bits. As shown in Figure 4, the first bit of the Activation field is used to indicate whether the channel decoding module is implemented based on AI, the second bit is used to indicate whether the symbol demodulation module is implemented based on AI, the third bit is used to indicate whether the resource demapping module is implemented based on AI, the fourth bit is used to indicate whether the waveform demodulation module is implemented based on AI, and the fifth bit is used to indicate whether the RF processing module is implemented based on AI. Optionally, when a bit of the Activation field is set to 1, it indicates that the functional module corresponding to the bit is implemented based on AI. When a bit of the Activation field is set to 0, it indicates that the functional module corresponding to the bit is not implemented based on AI. For example, a value of 11111 indicates that the channel decoding module, symbol demodulation module, resource demapping module, waveform demodulation module, and RF processing module are all implemented based on AI. For another example, a value of 10001 indicates that the channel decoding module and RF processing module are both implemented based on AI, and the symbol demodulation module, resource demapping module, and waveform demodulation module are not implemented based on AI. Alternatively, when the value of a bit of the activation field is 0, it indicates that the functional module corresponding to the bit is implemented based on non-AI. When the value of a bit of the activation field is 1, it indicates that the functional module corresponding to the bit is implemented based on AI.

[0306] Implementation 2: One or more functional modules are divided into R module groups, and the length of the first field is The value of the first field is used to indicate whether the functional modules in each of the R module groups are implemented based on AI, where R is an integer greater than or equal to 1.

[0307] For example, the first field is the activation field of the second DCI. As shown in Figure 4, the one or more functional modules include a channel decoding module, a symbol demodulation module, a resource demapping module, a waveform demodulation module, and a radio frequency processing module. The channel decoding module, symbol demodulation module, and resource demapping module constitute module group 1. The channel decoding module, symbol demodulation module, and waveform demodulation module constitute module group 2. The channel decoding module, waveform demodulation module, and radio frequency processing module constitute module group 3. In other words, R is equal to 3. Therefore, the length of the first field is 2 bits. As shown in Table 5, when the value of the first field is 00, it indicates that the functional modules in module group 1 are implemented based on AI, while the other functional modules are not. When the value of the first field is 01, it indicates that the functional modules in module group 2 are implemented based on AI, while the other functional modules are not. When the value of the first field is 10, it indicates that the functional modules in module group 3 are implemented based on AI, while the other functional modules are not. When the value of the first field is 11, it indicates that all functional modules are implemented based on AI.

[0308] Table 5

[0309] The above shows two possible implementations of the first field. This application is still applicable to other implementations, and this application does not limit them specifically. For example, the one or more functional modules are divided into R module groups, the length of the first field is R bits, each of the R bits corresponds to a module group, and different bits correspond to different module groups. This bit is used to indicate whether the functional modules in the module group corresponding to the bit are implemented based on AI. For example, the one or more functional modules include a channel decoding module, a symbol demodulation module, a de-resource mapping module, a waveform demodulation module, and a radio frequency processing module. The channel decoding module and the symbol demodulation module constitute module group 1, the de-resource mapping module and the waveform demodulation module constitute module group 2, and the radio frequency processing module is alone as module group 3. Therefore, the length of the first field can be 3 bits. Optionally, a bit in the first field has a value of 1, indicating that the functional module in the module group corresponding to the bit is implemented based on AI, and a bit in the first field has a value of 0, indicating that the functional module in the module group corresponding to the bit is implemented based on non-AI. Alternatively, a bit of the first field has a value of 0, indicating that the functional modules in the module group corresponding to the bit are implemented based on non-AI, and a bit of the first field has a value of 1, indicating that the functional modules in the module group corresponding to the bit are implemented based on AI. For example, a value of the first field is 111, indicating that the functional modules in module group 1, the functional modules in module group 2, and the functional modules in module group 3 are all implemented based on AI. For another example, a value of the first field is 100, indicating that the functional modules in module group 1 are all implemented based on AI, and the functional modules in module group 2 and the functional modules in module group 3 are all implemented based on non-AI.

[0310] The sixth indication information is the model index field in the second DCI, which is used to indicate the model parameters adopted by the AI-based functional module in the one or more functional modules.

[0311] Optionally, the sixth indication information further indicates relevant parameters adopted by the non-AI-implemented functional modules among the one or more functional modules.

[0312] Optionally, the embodiment shown in FIG9 further includes steps 902 and 903. Steps 902 and 903 may be performed after step 901.

[0313] 902. The first device determines parameters used by each of the one or more functional modules based on the fifth indication information and / or the sixth indication information.

[0314] 903. The first device establishes an air interface with the second device using parameters adopted by each of the one or more functional modules.

[0315] Optionally, if at least one of the one or more functional modules is implemented based on AI, the first device establishes a first type of air interface with the second device using parameters used by each of the one or more functional modules. If all of the one or more functional modules are implemented based on non-AI, the first device establishes a second type of air interface with the second device using parameters used by each of the one or more functional modules.

[0316] It should be noted that, in addition to the implementation shown in the fifth indication information in step 901 above, the second device may optionally send a seventh indication information to the first device. The seventh indication information is used to indicate whether each functional module in one or more functional modules is implemented based on AI. For example, the number of bits included in the seventh indication information is M is the number of the one or more functional modules. For example, the one or more functional modules include a channel decoding module, a symbol demodulation module and a waveform demodulation module. For example, if the value of the seventh indication information is 00, it means that each functional module in the one or more functional modules is implemented based on AI. If the value of the seventh indication information is 01, it means that the channel decoding module in the one or more functional modules is implemented based on AI, and the other functional modules are implemented based on non-AI. If the value of the seventh indication information is 10, it means that the symbol demodulation module in the one or more functional modules is implemented based on AI, and the other functional modules are implemented based on non-AI. If the value of the seventh indication information is 11, it means that the waveform demodulation module in the one or more functional modules is implemented based on AI, and the other functional modules are implemented based on non-AI. If the second device needs to indicate that the multiple functional modules are implemented based on AI, then the second device can send multiple seventh indication information to the first device. Each seventh indication information is used to indicate that the corresponding functional module is implemented based on AI.

[0317] In the embodiment shown in FIG9 above, the first device receives the fifth indication information and / or the sixth indication information from the second device. The fifth indication information is used to indicate whether each functional module in the one or more functional modules is implemented based on AI. The sixth indication information is used to indicate the model parameters adopted by the functional modules based on AI implementation in the one or more functional modules. This facilitates the first device to determine whether each functional module is implemented based on AI and the parameters adopted by each functional module. This enables the first device to establish a corresponding air interface with the second device. If all functional modules in the one or more functional modules are based on non-AI implementation, the first device establishes a second type of air interface with the second device. If some or all functional modules in the one or more functional modules are implemented based on AI, the first device establishes a first type of air interface with the second device.

[0318] In the present application, the first device may optionally transmit control plane information to the second device via a second type of air interface. For example, a signaling radio bearer 0 (SRBO), SRB1, or SRB3. The first device may transmit user plane information to the second device via a first type of air interface. For example, a data radio bearer (DRB).
