[0079] 6G systems can provide more dimensions of AI services, mainly including the following three aspects:

[0080] AI-enabled connectivity. That is, using AI methods to improve the performance of communication, such as using AI for beam management.

[0081] Computing power service. That is, the network side can provide computing power to the terminal side, such as helping the terminal to perform model training, model inference, etc.

[0082] Extreme AI service. That is, the transmission pipeline of the network is enhanced to improve the experience of AI application services.

[0083] In a positioning system, a terminal needs to receive PRS (Positioning Reference Signal) from multiple base stations, including not only the PRS of the serving base station but also the PRS of other neighboring cells for positioning. Therefore, the terminal not only needs the NW additional condition of the current serving cell, but also needs the NW additional condition of other non-serving cells participating in positioning.

[0084] The NW additional condition is used to describe information related to network configuration or network implementation. For example, the downtilt angle of the network side antenna, the beam width, etc. The terminal side needs to understand the network additional condition in the process of data collection, model management, etc. to ensure the consistency of the characteristics of the training data and the model inference data. On the other hand, the network side does not want to expose specific network private information to the terminal, so the concept of associated ID is introduced. Specifically, the network side will map a certain NW additional condition to an associated ID, and the terminal side does not know the real physical meaning represented by a certain associated ID. The terminal side only needs to compare the associated ID received when collecting training data with the associated ID received when performing model inference, to determine whether the current model is applicable to the network environment.

[0085] Therefore, the present disclosure proposes a communication method and device, a communication system, a communication device, and a storage medium. The first network device sends first information to the terminal, so that the terminal obtains the NW additional condition of the serving cell and the NW additional condition of the non-serving cell.

[0086] The method proposed in the present disclosure is applicable to various communication systems, including but not limited to 4G, 5G, 5G-advance, and subsequent communication technologies (such as 6G, etc.).

[0114] FIG. 2 is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2, the present embodiment relates to a communication method, which can be performed by a communication system, for example, the communication system 100 shown in FIG. 1. The communication system includes a terminal, a first network device, and a plurality of second network devices. The interaction method can include the following steps:

[0115] Step 2101, the terminal sends a first request message to the first network device.

[0116] In some embodiments, the first request message is used to request the first information.

[0117] In some embodiments, the terminal deploys an artificial intelligence (AI) model or AI function, and the first information is used for the terminal to perform management of the AI model or AI function.

[0118] In some embodiments, the first request message is applicable to a positioning private protocol (LPP).

[0119] For example, the terminal sends a request message for network additional conditions to an LMF, for example, by sending a Request NW additional condition through LPP.

[0120] In some embodiments, the name of the first request message is not limited, for example, it is a “request message for network additional conditions”, a “request message for the first information”, etc., and the present disclosure is not limited in this regard.

[0121] Step 2102, the first network device sends a second request message to a plurality of second network devices.

[0122] In some embodiments, the second request message is used to request a network additional condition corresponding to each of the plurality of second network devices.

[0123] In some embodiments, the first network device sends the second request message to each of the second network devices to request the second network devices to feed back the network additional conditions.

[0124] For example, the LMF requests a PRS-associated NW additional condition from each base station.

[0125] In some embodiments, the name of the second request message is not limited, for example, it is a “request message for network additional conditions”.

[0126] For example, the LMF sends an NRPPa MEASUREMENT REQUEST (NW additional conditions) to a base station of a serving cell of the terminal and a base station of a non-serving cell of the terminal.

[0127] Step 2103, the second network device sends a network additional condition to the first network device.

[0128] In some embodiments, the plurality of second network devices send respective network additional conditions to the first network device in response to the second request message.

[0129] Exemplarily, the base station of the serving cell and the base station of the non-serving cell of the terminal send the LMF the NW additional condition associated with the PRS.

[0130] Exemplarily, the base station of the serving cell and the base station of the non-serving cell of the terminal send the LMF the NRPPa MEASUREMENT RESPONSE (NW additional condition).

[0131] In step 2104, the first network device sends a first indication message to the terminal.

[0132] In some embodiments, the first information is included in the first indication message.

[0133] In some embodiments, the first indication message is applicable to a positioning private protocol LPP.

[0134] In some embodiments, the first network device indicates the NW additional condition to the terminal through LPP signaling, and the signaling that can be used includes “ProvideAssistanceData”.

[0135] In some embodiments, the first information is used for management of the AI model or AI function performed by the terminal.

[0136] In some embodiments, the first information is used to respectively indicate the respective network additional conditions of the plurality of second network devices that send PRS, or to uniformly indicate the combined network additional conditions of the plurality of second network devices that send PRS.

[0137] In some embodiments, the first information is used to indicate the network additional condition associated with the positioning reference signal PRS received by the terminal, and the first information includes the network additional condition associated with the PRS sent by the serving cell of the terminal and the network additional condition associated with the PRS sent by the non-serving cell of the terminal.

[0138] Exemplarily, the AI model or AI function is deployed on the terminal side, and the terminal side receives information from the LMF when performing data collection or AI model or AI function management, and the information from the LMF is used to indicate the NW additional condition associated with the PRS received by the terminal. The NW additional condition associated with the received PRS includes the NW additional condition associated with the PRS of the serving cell and the NW additional condition associated with the PRS of the non-serving cell.

[0139] For example, the LMF indicates the NW additional condition to the terminal through LPP signaling. The signaling that can be used includes "ProvideAssistanceData".

[0140] For example, before the LMF sends the NW additional condition, the sending can be based on a request from the terminal side.

[0141] For example, the NW additional condition on the base station side can be PRS information, beam information, implementation information of the transmitting antenna, and the like sent by the network side.

[0142] For example, the NW additional condition corresponding to each TRP / base station that transmits PRS can be indicated separately, or a unified associated ID can be used to indicate the combined NW additional condition of the current multiple TRPs.

[0143] In some embodiments, the network additional condition associated with the PRS transmitted by the serving cell of the terminal and the network additional condition associated with the PRS transmitted by the non-serving cell of the terminal included in the first information can be used for management of the AI model or AI function of the terminal.

[0144] The communication method related to the embodiments of the present disclosure can include at least one of steps 2101-2104. For example, step 2101 can be implemented as an independent embodiment, step 2102 can be implemented as an independent embodiment, and so on, but not limited to this.

[0149] In some embodiments, the first network device and the plurality of second network devices can interact based on NRPPa signaling.

[0150] In some embodiments, the first network device sends the third request message to the base station of the serving cell of the terminal and the base station of the non-serving cell to configure network additional conditions for the serving cell and the non-serving cell.

[0151] For example, the LMF sends the NW additional condition associated with each TRP to each base station.

[0152] For example, the LMF requests the NW additional condition associated with PRS from each base station.

[0153] For example, the LMF and each base station can interact based on NRPPa signaling, such as Measurement request.

[0154] For example, the LMF sends the NRPPa MEASUREMENT REQUEST (NW additional conditions configuration) to the base station of the serving cell of the terminal and the base station of the neighboring cell.

[0155] In some embodiments, the name of the third request message is not limited, for example, it is "network additional condition configuration message", "PRS request message", etc., and the present disclosure is not limited to this.

[0156] Step 3102, the second network device sends PRS to the terminal.

[0157] In some embodiments, the plurality of second network devices sends respective PRS to the terminal.

[0158] In some embodiments, the PRS is sent by the plurality of second network devices according to the network additional conditions associated with the plurality of second network devices indicated by the first network device.

[0159] In some embodiments, the terminal deploys an artificial intelligence (AI) model or AI function.

[0160] For example, each base station sends PRS according to the indication of the LMF.

[0161] In some embodiments, the base station of the serving cell and the base station of the neighbor cell of the terminal send PRS to the terminal.

[0162] For example, the base station of the serving cell and the base station of the non-serving cell send PRS transmission to the terminal based on the configured NW additional condition.

[0163] In step 3103, the terminal sends a first request message to the first network device.

[0164] In some embodiments, the first request message is used to request the first information.

[0166] For example, the terminal sends a request message for the network additional condition to the LMF, for example, by LPP.

[0167] In some embodiments, the name of the first request message is not limited, for example, “request message for network additional condition”, “request message for first information”, etc., which is not limited by the present disclosure.

[0168] In step 3104, the first network device sends a first indication message to the terminal.

[0169] In some embodiments, the first information is included in the first indication message, and the first indication message is applicable to a positioning private protocol LPP.

[0170] In some embodiments, the first network device indicates the NW additional condition to the terminal by LPP signaling, and the signaling that can be used includes “ProvideAssistanceData”.

[0171] In some embodiments, the first information is used for the terminal to perform management of the AI model or the AI function.

[0172] In some embodiments, the first information is used to respectively indicate the network additional condition corresponding to each of the plurality of second network devices that send PRS, or uniformly indicate the combined network additional condition of the plurality of second network devices that send PRS.

The associated NW additional condition of the received PRS includes the NW additional condition associated with the PRS of the serving cell and the NW additional condition of the non-serving cell.

[0175] For example, before the LMF sends the NW additional condition, it can be sent based on the request of the terminal side.

[0177] For example, the LMF indicates the NW additional condition to the terminal through LPP signaling. The signaling that can be used includes “ProvideAssistanceData”.

[0178] For example, the NW additional condition corresponding to each TRP / base station sending PRS can be indicated separately, or a unified associated ID can be used to indicate the combined NW additional condition of the current multiple TRPs.

[0179] In some embodiments, the network additional condition associated with the PRS sent by the serving cell of the terminal and the network additional condition associated with the PRS sent by the non-serving cell of the terminal included in the first information can be used for management of the AI model or AI function of the terminal.

[0227] The following is a specific scheme of a communication method provided by the present disclosure, as shown in the interaction diagram of FIG. 7A or FIG. 7B.

[0228] 1. Interaction between LMF and terminal:

[0229] The AI model or AI function is deployed on the terminal side. When the terminal side collects data or manages the AI model or AI function, the terminal side receives information from the LMF indicating the NW additional condition associated with the PRS received by the terminal. The associated NW additional condition of the received PRS includes both the NW additional condition associated with the serving cell PRS and the NW additional condition associated with the non-serving cell PRS. As shown in step 4 of FIG. 7A or step 4 of FIG. 7B.

[0230] Optionally, the information received by the terminal from the LMF can be a first indication message, and the first indication message includes first information.

[0231] Indication of NW additional condition:

[0232] Method one: the NW additional condition corresponding to each TRP / base station sending PRS can be indicated separately. As shown in Table 1, the Associated ID corresponding to TRP ID / cell ID x is 1; the Associated ID corresponding to TRP ID / cell ID xy is 2; and so on.

[0233] Table 1:

[0234] Method two: a unified associated ID is used to indicate the combined NW additional condition of the current multiple TRPs.

[0235] Indication signaling: the LMF indicates the NW additional condition to the terminal through LPP signaling. The signaling that can be used includes “ProvideAssistanceData”.

[0236] Before the LMF sends the NW additional condition, it can be based on the request of the terminal side. As shown in step 1 of FIG. 7A or step 3 of FIG. 7B.

[0237] Optionally, the request of the terminal can be a first request message for requesting first information.

[0238] The NW additional condition on the base station side can be the PRS information, beam information, implementation information of the transmitting antenna, etc. sent by the network side.

[0239] 2. Interaction between LMF and each TRP:

[0240] Way one: Before performing the point 1, the LMF also needs to obtain the NW additional condition of each TRP sending PRS. The main steps include that the LMF requests the NW additional condition associated with PRS from each base station and each base station feeds back the NW additional condition associated with PRS to the LMF. As shown in steps 2 and 3 in FIG. 7A.

[0241] Optionally, the first network device sends a second request message to the plurality of second network devices, and receives network additional conditions sent by the plurality of second network devices in response to the second request message.

[0242] The LMF and each base station can interact based on NRPPa signaling, for example, Measurement request.

[0243] Way two: The LMF sends the NW additional condition associated with each TRP to each base station, and each base station performs PRS transmission according to the indication of the LMF. As shown in steps 1 and 2 in FIG. 7B.

[0244] Optionally, the first network device sends a third request message to the plurality of second network devices, and the third request message includes the network additional condition configured by the first network device for the plurality of second network devices, and the third request message is used to instruct the plurality of second network devices to send PRS to the terminal according to the indicated network additional condition.

[0245] Optionally, the optional implementation manner of the embodiment shown in FIG. 7A can refer to the related steps in the embodiment shown in FIG. 2; and the optional implementation manner of the embodiment shown in FIG. 7B can refer to the related steps in the embodiment shown in FIG. 3.

[0247] The embodiments of the present disclosure also propose a device for implementing any of the above methods, for example, a device including units or modules for implementing each step performed by the terminal in any of the above methods. For another example, another device is proposed, including units or modules for implementing each step performed by the network device (such as an access network device, a core network function node, a core network device, etc.) in any of the above methods.

[0248] It should be understood that the division of each unit or module in the above apparatus is only a logical function division, and all or part of them can be integrated into a physical entity or physically separated in actual implementation. In addition, the units or modules in the apparatus can be implemented in the form of processor calling software: for example, the apparatus includes a processor, the processor is connected with a memory, the memory stores instructions, and the processor calls the instructions stored in the memory to realize any of the above methods or realize the functions of each unit or module of the above apparatus, wherein the processor is a general processor such as a central processing unit (CPU) or a microprocessor, and the memory is a memory in the apparatus or a memory outside the apparatus. Alternatively, the units or modules in the apparatus can be implemented in the form of hardware circuit, and the functions of part or all of the units or modules can be realized by the design of hardware circuit. The above hardware circuit can be understood as one or more processors; for example, in one implementation, the above hardware circuit is an application-specific integrated circuit (ASIC), and the functions of part or all of the units or modules are realized by the design of the logical relationship of elements in the circuit; for another example, in another implementation, the above hardware circuit is a programmable logic device (PLD), and a field programmable gate array (FPGA) is taken as an example, which can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by a configuration file, so as to realize the functions of part or all of the above units or modules. All units or modules of the above apparatus can be all implemented in the form of processor calling software, or all implemented in the form of hardware circuit, or part implemented in the form of processor calling software and the remaining part implemented in the form of hardware circuit.

In one implementation, the processor can be a circuit with instruction reading and running capability, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), a digital signal processor (DSP), or the like. In another implementation, the processor can implement certain functions through a logical relationship of hardware circuit. The logical relationship of the hardware circuit is fixed or reconfigurable. For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the processor loads a configuration document to implement the configuration of the hardware circuit. It can be understood that the processor loads instructions to implement the functions of part or all of the units or modules described above. In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), or the like.
