[0026] As advanced information technology (IT) simulation technologies, represented by digital twins (DT), become deeply integrated into future wireless systems, the native architecture, features, business processes, and performance of 5G-Advanced (5G-A) and sixth-generation mobile communications (6G) wireless systems will be impacted and optimized. Leveraging the real-world digital drive, twin modeling, simulation, and pre-verification capabilities of digital twins, various operational performance aspects of 5G-A and 6G wireless systems can be optimized and enhanced, improving the service experience for 5G-A and 6G mobile users. Figure 1 A schematic diagram of the wireless system provided in this application is shown in FIG. Figure 1 As shown, in a wireless system, the terminal equipment (User Equ ipment, UE) and the network side (Network, NW) realize the transmission of business application data based on business application protocols, communication air interface protocols and radio signals, and complete communication business services. All communication business service behaviors of mobile terminal users or network side are based on real event requirements for objective purposes and will be physically executed. In the system operation state, the current wireless system basically does not have digital modeling and simulation operations for network physical entity objects. This application proposes a wireless communication method to realize digital twins for network physical entity objects.

[0027] The basic principle of wireless network digital twin technology can be: according to the specific target twin tasks of system users (for example, wireless network operation and maintenance personnel), real-time data collection and modeling fidelity reproduction of specific "physical objects" (i.e., twinned objects) in the real physical network are carried out, thereby constructing a corresponding "digital twin" (i.e., a digital spatial mapping of the "physical object"). In this way, system users can, to a certain extent, foresee, predict, and pre-verify the inherent causal relationships such as the trend direction, state, condition path effect, etc. of the future changes of the "physical object". Therefore, in order to realize the communication interaction between the terminal and the base station, how the base station or the terminal obtains the corresponding information requires further research.

[0028] To make the purpose, technical solutions and advantages of this application more clear, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of this application can be combined with each other in any way.

[0029] The steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions. Also, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be performed in an order different from that shown here.

[0030] In this application, the terms "first", "second", etc. are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

For example, the smaller the level, the higher the demand, and the terminal prioritizes uploading the corresponding report. The indication information of whether to transmit the digital twin report in segments includes indication information of whether to report the digital twin report in segments (in the scenario where the first communication node is a terminal and the second communication node is a base station) and indication information of whether to send the digital twin report in segments (in the scenario where the first communication node is a base station and the second communication node is a terminal).

The control unit of media control is MAC CE (MAC Control Element). For example, the logical channel identifier (Logical Channel Identification, LCID) reserved in the downlink shared channel (Down link Shared Channel, DLSCH) indicates a predefined MAC CE format containing the above-mentioned indication information, or DCI, for example, by predefining a DCI format that carries auxiliary information for clock source switching.

[0109] The key indicators reported by the digital twin are cached. The key indicators are not limited here and can be pre-set.

[0110] The digital twin report is cached based on its time information. For example, the latest generated digital twin report is stored, or the latest digital twin report overwrites the old digital twin report.

[0111] Caching is performed based on the start time of the digital twin. For example, the digital twin report generated corresponding to the most recent digital twin simulation is stored, or the digital twin report generated corresponding to the most recent digital twin simulation overwrites the old digital twin report.

[0112] In the case of multiple types of digital twin simulations, the digital twin reports are stored based on the priority of the digital twin report cache. For example, the corresponding digital twin reports are stored according to the corresponding priority of each measurement configuration of the base station terminal.

Based on the indication information, the base station instructs the terminal to report the digital twin report information through a dedicated signaling in the connected state. For a non-connected state or when the digital twin report does not need to be sent in a timely manner, when the terminal reports the digital twin report, it also includes the configuration information of the digital twin in the report and sends it to the base station.

For example, the digital twin report information is reported by dedicated signaling in the connected state.
