Technical Field

[0001] This application relates to the field of communication technology, and in particular to a data transmission method and apparatus. Background Technology

[0002] In recent years, with the continuous advancement and improvement of extended reality (XR) technology, related industries have experienced rapid development. Virtual reality technology has now entered various fields closely related to people's production and daily life, including education, entertainment, military, healthcare, environmental protection, transportation, and public health. Compared to traditional video services, virtual reality (VR) offers advantages such as multiple perspectives and strong interactivity, providing users with a completely new visual experience and possessing immense application value and commercial potential. XR is a collective term for virtual reality (VR), augmented reality (AR), and mixed reality (MR), and it is widely used in entertainment, gaming, healthcare, advertising, industry, online education, engineering, and many other fields.

[0003] With the continuous development and improvement of VR devices, content, platforms, and even 5G and next-generation network systems, researching effective transmission methods for XR services and improving network capacity for XR services can effectively promote the development of the end-to-end (E2E) industry. Therefore, effective transmission methods for XR services have significant practical value. Summary of the Invention

[0004] This application provides a communication method and apparatus.

[0005] In a first aspect, embodiments of this application provide a communication method, which can be executed by a wireless access network device or by a component of the wireless access network device (e.g., a processor, chip, or chip system), comprising: obtaining service feature configuration information of data; configuring data to be transmitted in the data based on the service feature configuration information, and untransmitted data and / or transmitted data in the data; and communicating with a terminal based on the configuration of the data to be transmitted. Optionally, the data is obtained by a server encoding and / or rendering source data for XR.

[0006] This method designs a transmission method from the perspective of improving the accuracy of XR video frames, video frame striping, or video frame fragmentation and the satisfaction rate of cell users. It enables the complete transmission of XR video services, thereby improving the accuracy of XR data packets and the satisfaction rate of cell users, and enhancing the user experience of XR services. The aforementioned video frame fragmentation or video frame striping refers to the fact that video frames can be encoded according to regional divisions during encoding, and the divided regions are called video frame fragmentation or video frame striping.

[0007] In conjunction with the first aspect, in some embodiments of the first aspect, the aforementioned data may correspond to the data of a single frame, the data of the same slice within a frame, or the data of the same tile within a frame. This allows the data of the same frame, the data of the same slice within a frame, or the data of the same tile within a frame to be transmitted as a whole on the wireless access network device side, thereby improving the user's experience with the video feed. It is understood that the frame in this application may also be a video frame or a data frame, etc., and this application does not specifically limit the specific frame.

[0008] In conjunction with the first aspect, in certain embodiments of the first aspect, obtaining the service characteristic configuration information of the data includes: obtaining the service characteristic configuration information based on the configuration of the core network elements. Through this embodiment, data can be transmitted with integrity on the radio access network device side according to the core network's requirements for data integrity transmission, thereby improving the user experience of XR services.

[0009] In conjunction with the first aspect, in some embodiments of the first aspect, the aforementioned service feature configuration information indicates the service type information and / or integrity information of the aforementioned data. The service type information indicates the service type to which the aforementioned data belongs (e.g., XR service). The integrity information may indicate one or more of the following: whether multiple data packets belong to a single entity; whether multiple data packets need to be transmitted as a single entity; the frame information, frame strip information, or frame fragment information to which the multiple data packets belong; and the data size information of the frame, frame strip, or frame fragment to which the multiple data packets belong. It is understood that the data size in this application may refer to the number of data packets or other data size parameters. Through this embodiment, data from the same frame, the same fragment data, or the same strip data can be transmitted as a single entity, thereby improving the user's experience of the video image.

[0010] In conjunction with the first aspect, in certain embodiments of the first aspect, the aforementioned service feature configuration information includes one or more of the following: 5G Quality of Service Identity (5QI) information, Quality of Service Flow Identifier (QFI) information, Quality of Service Profile (QoS) information, bearer information, or General Packet Radio Service Tunneling Protocol (GTP) information. This embodiment enables the aforementioned service feature configuration information to be received and identified, thereby supporting the integrity transmission of data in the radio access network equipment and improving the user experience of XR services.

[0011] For example, the service type information indicated by the service characteristic configuration information can be carried through the service type information attribute in 5QI information, QFI information, quality of service template information, or GTP information, or it can be implemented by the core network by configuring corresponding bearer information or corresponding 5QI information for XR services. In this way, radio access network devices can obtain the service type information corresponding to the aforementioned data.

[0012] For example, the integrity information indicated by the service feature configuration information can be carried through integrity information attributes in 5QI information, QFI information, quality of service template information, or GTP information, or it can be implemented by the core network by configuring corresponding bearer information or corresponding 5QI information for XR services. In this way, radio access network devices can obtain the integrity information of the services corresponding to the above data.

[0013] In conjunction with the first aspect, in some embodiments of the first aspect, service feature configuration information can be configured to the radio access network device by core network elements (such as session management function (SMF) network elements or user plane function (UPF) network elements). The radio access network device obtains the service feature configuration information according to the configuration of the core network elements. In this way, the radio access network device can identify and receive the service feature configuration information corresponding to the aforementioned data.

[0014] In conjunction with the first aspect, in some embodiments of the first aspect, the service type of the aforementioned data is determined by sensing the data volume and periodicity of the data. For example, if the data is perceived to arrive periodically and the data volume is greater than a first threshold (e.g., 1 megabit), then the service type of the data can be determined to be an XR service type. This method effectively reduces the overhead of transmission signaling, improves the utilization efficiency of transmission resources, and enhances the user experience of XR services.

[0015] In conjunction with the first aspect, in some embodiments of the first aspect, configuring the data to be transmitted in the aforementioned data based on the untransmitted data and / or transmitted data includes: setting a priority for the data to be transmitted in the aforementioned data based on the untransmitted data and / or transmitted data. This method sets the priority for user data packet transmission scheduling, thereby improving the accuracy of XR video frame transmission and the overall user satisfaction rate of the cell, and enhancing the user experience of XR services.

[0016] In conjunction with the first aspect, in certain embodiments of the first aspect, priority settings are made for data to be transmitted based on untransmitted data and / or transmitted data. This includes setting the priority of the data to be transmitted based on one or more of the following: the amount of untransmitted data and / or the amount of transmitted data, the transmission delay of the transmitted data, the estimated transmission delay of the untransmitted data, the correct reception rate of the transmitted data, the instantaneous transmission rate, or the historical transmission rate. By setting the priority of user data packet transmission scheduling in this way, the accuracy of XR video frame transmission and the overall user satisfaction rate of the cell are improved, thereby enhancing the user experience of XR services.

[0017] In conjunction with the first aspect, in certain embodiments of the first aspect, the data to be transmitted in the aforementioned data is configured based on the untransmitted data and / or transmitted data, including: not transmitting data units containing the data to be transmitted based on the untransmitted data and / or transmitted data. This method ensures the complete transmission of user data packets, thereby improving the accuracy of XR video frame transmission and the overall user satisfaction rate of the cell, and enhancing the user experience of XR services.

[0018] In conjunction with the first aspect, in certain embodiments of the first aspect, data units that do not send data to be transmitted based on the untransmitted data and / or transmitted data include: data units that do not send the data to be transmitted when there is a data transmission error in the transmitted data, or when the estimated transmission time of the untransmitted data is greater than a transmission time threshold, or when the correct reception rate of the transmitted data is less than a correct reception rate threshold. This method ensures the integrity of user data packets during transmission, thereby improving the accuracy of XR video frame transmission and the overall user satisfaction rate of the cell, and enhancing the user experience of XR services.

[0019] In conjunction with the first aspect, in some embodiments of the first aspect, communicating with a terminal based on the configuration of the data to be transmitted includes: sending transmission indication information of the data to be transmitted to the terminal, the transmission indication information being used for processing transmitted data. Optionally, the transmission indication information is used to indicate the integrity transmission criteria of the data, the number of data packets contained in the data to be transmitted, and the data unit to which the data packets of the data to be transmitted belong. Optionally, the transmission indication information is used to indicate the data unit to which data packets to be transmitted that are not sent belong. In this way, the integrity transmission requirements of XR video frames can be supported, improving the user experience of XR services.

[0020] The aforementioned transmission indication information can be carried by radio resource control (RRC) messages, downlink control information (DCI), or media access control control element (MAC CE). For example, a radio access network (RAN) device may use an RRC message to notify a terminal of the integrity transmission criteria for the current service, the number of data packets contained in the data to be transmitted, the data unit to which the data packets to be transmitted belong, and the data unit to which the data packets to be untransmitted belong. Alternatively, the RAN device may use an RRC message to notify a terminal of the integrity transmission criteria for the current service, and use DCI or MAC CE to indicate the number of data packets contained in the data to be transmitted, the data unit to which the data packets to be transmitted belong, and the data unit to which the data packets to be untransmitted belong. Again, the RAN device may use DCI or MAC CE to indicate the integrity transmission criteria, the number of data packets contained in the data to be transmitted, the data unit to which the data packets to be transmitted belong, and the data unit to which the data packets to be untransmitted belong.

[0021] Secondly, embodiments of this application provide a communication method, which can be executed by a terminal device or by a component of a user terminal device (e.g., a processor, chip, or chip system), including: receiving transmission indication information from a wireless access network device, and performing integrity reception of data according to the transmission indication information. Optionally, the data is obtained by a server encoding and / or rendering source data for XR.

[0022] This method enables the transmission of XR video data with integrity tailored to the specific characteristics of the service, thereby improving the accuracy of XR data packets and the satisfaction rate of cell users, and ultimately enhancing the user experience of XR services.

[0023] In conjunction with the second aspect, in some embodiments of the second aspect, the aforementioned data may correspond to the data of a frame, the data of the same segment within a frame, or the data of the same strip within a frame. This allows the data of the same frame, the data of the same segment within a frame, or the data of the same strip within a frame to be transmitted as a whole, thereby improving the user's experience with the video.

[0024] In conjunction with the second aspect, in some embodiments of the second aspect, receiving data with integrity according to transmission indication information includes: processing the transmitted data according to the transmission indication information. Optionally, the transmission indication information indicates the integrity transmission criteria of the data, the number of data packets contained in the data to be transmitted, and the data unit to which the data packets of the data to be transmitted belong. Optionally, the transmission indication information is used to indicate the data unit to which data packets to be transmitted that are not sent belong. In this way, the terminal can drop all or part of the data packets of the video frame according to this information, reducing the transmission of data that does not contribute to the XR data experience, thereby reducing the waste of transmission resources and improving the efficiency of transmission resource utilization.

[0025] The aforementioned transmission indication information can be carried by RRC messages, DCI, or MAC CE. For example, a radio access network device may use an RRC message to notify a terminal of the current service integrity transmission rules, the number of data packets contained in the data to be transmitted, the data unit to which the data packets to be transmitted belong, and the data unit to which the data packets to be transmitted but not transmitted belong. Alternatively, a radio access network device may use an RRC message to notify a terminal of the current service integrity transmission rules, and use DCI or MAC CE to indicate the number of data packets contained in the data to be transmitted, the data unit to which the data packets to be transmitted belong, and the data unit to which the data packets to be transmitted but not transmitted belong. Again, a radio access network device may use DCI or MAC CE to indicate the integrity transmission rules, the number of data packets contained in the data to be transmitted, the data unit to which the data packets to be transmitted belong, and the data unit to which the data packets to be transmitted but not transmitted belong.

[0026] In one possible implementation of receiving data with integrity based on the aforementioned transmission indication information, the terminal determines, based on the transmission indication information, that if there are data packets with reception errors, it clears the data packets of the currently received frame, including both successfully decoded and undecoded data packets. By clearing all or part of the data packets in the erroneous video frame in this way, data transmission that does not contribute to the XR data experience can be reduced, thereby reducing the waste of transmission resources and improving the efficiency of transmission resource utilization.

[0027] In another possible implementation of receiving data with integrity based on the aforementioned transmission indication information, when the terminal learns from the transmission indication information that packet loss has occurred in the wireless access network device, it clears the data packets of the currently received frame, including both successfully decoded and undecoded data packets. By clearing all or part of the data packets of the erroneous video frame in this way, data transmission that does not contribute to the XR data experience can be reduced, thereby reducing the waste of transmission resources and improving the efficiency of transmission resource utilization.

[0047] The methods and apparatus provided in this application can be applied to communication systems. Figure 1 This is a schematic diagram of the architecture of the communication system 1000 used in an embodiment of this application. Figure 1 As shown, the communication system includes a wireless access network 100 and a core network 200. The wireless access network 100 may include at least one wireless access network device (such as...). Figure 1 110a and 110b in the above), may also include at least one terminal (such as Figure 1 (Referring to 120a-120j in the original text). Terminals connect wirelessly to the wireless access network (WLAN) equipment, which in turn connects to the core network via wireless or wired connections. The core network equipment and the WLAN equipment can be independent physical devices, or they can integrate the functions of the core network equipment and the logical functions of the WLAN equipment onto the same physical device. Alternatively, a single physical device can integrate some of the functions of both the core network equipment and the WLAN equipment. Terminals and WLAN equipment can be interconnected via wired or wireless connections. Figure 1 This is just an illustration; the communication system may also include other network devices, such as wireless repeaters and wireless backhaul devices. Figure 1 It is not shown in the middle.

[0048] Radio access network equipment can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a 5G mobile communication system, a next-generation base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system; it can also be a module or unit that performs some of the functions of a base station, for example, it can be a central unit (CU) or a distributed unit (DU). Radio access network equipment can be a macro base station (such as... Figure 1 110a in the text), can also be a micro base station or an indoor station (such as... Figure 1110b) in the text can also be a relay node or a donor node, etc. The embodiments of this application do not limit the specific technology or device form used in the wireless access network equipment. For ease of description, the following description uses a base station as an example of a wireless access network device.

[0049] In this application, the terminal can be a terminal in an Internet of Things (IoT) system. IoT is an important component of future information technology development, and its main technical feature is connecting objects to networks through communication technologies, thereby realizing an intelligent network of human-machine interconnection and object-to-object interconnection. The terminal in this application can be a terminal in machine-type communication (MTC). The terminal in this application can be an on-board module, on-board component, on-board chip, or on-board unit built into a vehicle as one or more components or units. The vehicle can implement the methods of this application through the built-in on-board module, on-board component, on-board chip, or on-board unit. Therefore, the embodiments of this application can be applied to vehicle networking, such as vehicle-to-everything (V2X), long-term evolution vehicle (LTE-V) communication, and vehicle-to-vehicle (V2V) communication.

[0050] The terminal in this application can also be a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, or a mixed reality (MR) terminal device. VR terminals, AR terminals, and MR terminals can all be referred to as extended reality (XR) terminal devices. XR terminals can be, for example, head-mounted devices (such as helmets or glasses), all-in-one devices, televisions, monitors, automobiles, in-vehicle devices, tablets, smart screens, holographic projectors, video players, remote-controlled robots, tactile internet terminals, etc. XR terminals can present XR data to users, allowing users to experience diverse XR services by wearing or using the XR terminal. XR terminals can access networks wirelessly or via wired means, such as through wireless-fidelity (WiFi) or 5G systems. Base stations and terminals can be fixed or mobile. Base stations and terminals can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can be deployed in the air on airplanes, balloons, and artificial satellites. The embodiments of this application do not limit the application scenarios of base stations and terminals.

[0051] The roles of base stations and terminals can be relative, for example, Figure 1 The helicopter or drone 120i can be configured as a mobile base station. For terminals 120j accessing the wireless access network 100 via 120i, terminal 120i is a base station; however, for base station 110a, 120i is a terminal, meaning that 110a and 120i communicate via a wireless air interface protocol. Of course, 110a and 120i can also communicate via a base station-to-base station interface protocol; in this case, 120i is also a base station relative to 110a. Therefore, both base stations and terminals can be collectively referred to as communication devices. Figure 1 The 110a and 110b in the text can be referred to as communication devices with base station functions. Figure 1 The 120a-120j in the text can be referred to as communication devices with terminal functions.

[0052] Communication between base stations and terminals, between base stations, and between terminals can be conducted using licensed spectrum, unlicensed spectrum, or both simultaneously. Communication can be conducted using spectrum below 6 GHz, spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used for wireless communication.

[0053] In the embodiments of this application, the functions of the base station can be executed by modules (such as chips) within the base station, or by a control subsystem that includes base station functions. This control subsystem, including base station functions, can be a control center in the application scenarios of the aforementioned terminals, such as smart grids, industrial control, intelligent transportation, and smart cities. Similarly, the functions of the terminal can be executed by modules (such as chips or modems) within the terminal, or by a device that includes terminal functions.

[0054] In this application, the base station sends downlink signals or downlink information to the terminal, and the downlink information is carried on the downlink channel; the terminal sends uplink signals or uplink information to the base station, and the uplink information is carried on the uplink channel; the terminal sends sidelink signals or sidelink information to the terminal, and the sidelink information is carried on the sidelink channel. The sidelink can also be referred to as a side link, lateral link, or side link, etc.

[0055] The methods and apparatus provided in this application can be applied to various communication system architectures. For example... Figure 2A schematic diagram of a communication system architecture is shown. In this architecture, the terminal accesses the core network through a radio access network (RAN) device. The terminal can establish a connection with a data network (DN) or a server within the data network through the RAN and core network. The data network may include, for example, operator services, the Internet, or third-party services. In fourth-generation (4G) mobile communication systems, this connection can be a packet data network connection (PDN connection) or a bearer. In 5G communication systems, this connection can be a protocol data unit session (PDUSession). In future communication systems such as 6G, this connection can be a PDU session, a PDN connection, or other similar concepts; this application embodiment does not limit this. In this application embodiment, the connection established between the terminal and the data network or server can also be referred to as a session.

[0056] The core network includes mobility management network elements, session management network elements, and user plane network elements. Optionally, the core network may also include network capability exposure network elements and / or policy control network elements.

[0057] Mobility management network elements are primarily used for mobility management in mobile networks, such as user location updates, user registration with the network, and user handover. In 4G communication systems, the mobility management network element can be a mobility management entity (MME). In 5G communication systems, the mobility management network element can be an access and mobility management function (AMF).

[0058] Session management network elements are primarily used for session management in mobile networks, such as session establishment, modification, and release. Specific functions include assigning Internet Protocol (IP) addresses to users and selecting user plane network elements to provide packet forwarding capabilities. In 4G communication systems, session management network elements can be Serving Gateway Control Plane (SGW-C), Packet Data Network Gateway Control Plane (PGW-C), or a combination of SGW-C and PGW-C. In 5G communication systems, session management network elements can be Session Management Functions (SMF).

[0059] User plane network elements are primarily used to forward user data packets according to the routing rules of session management network elements. In 4G communication systems, user plane network elements can be Serving Gateway User Plane (SGW-U), Packet Data Network Gateway User Plane (PGW-U), or a combination of SGW-U and PGW-U. In 5G communication systems, user plane network elements can be User Plane Function (UPF) network elements.

[0060] Policy control network elements include user subscription data management functions, policy control functions, charging policy control functions, and quality of service (QoS) control. In 4G communication systems, the policy control network element can be the policy control and charging function (PCRF). In 5G communication systems, the policy control network element can be the policy control function (PCF).

[0061] Network capability open elements are primarily used to expose the capabilities of the communication system to third parties, application services, and other functionalities, facilitating information exchange between third parties, application servers, and the communication system. In 4G communication systems, network capability open elements can be service capability exposure functions (SCEF). In 5G communication systems, network capability open elements can be network exposure functions (NEF).

[0062] In future communication systems such as 6G, the aforementioned network elements or devices may still use the names they used in 4G or 5G communication systems, or they may have other names. The functions of the aforementioned network elements or devices may be performed by a single network element or by several network elements working together; this application does not limit this.

[0063] In practical deployments, network elements in the core network can be deployed on the same or different physical devices. For example, as one possible deployment, the AMF and SMF can be deployed on the same physical device. As another example, 5G core network elements can be deployed on the same physical device as 4G core network elements.

[0064] In actual deployment, network elements in the core network can be co-located. For example, mobility management network elements can be co-located with session management network elements. Similarly, session management network elements can be co-located with user plane network elements. When two or more network elements are co-located, the interaction between these two or more network elements provided in this application becomes an internal operation of that co-located network element or can be omitted.

[0065] Compared to the core network of 4G communication systems, the core network of 5G communication systems adopts an architecture that separates the control plane and user plane, as well as a service-oriented architecture. It is understood that the solution in this application is applicable not only to 5G communication systems, but also to evolved 4G communication systems, or future 6G communication systems. The network to which this solution is applicable can adopt an architecture that separates the control plane and user plane, or an architecture that unifies the control plane and user plane. The network to which this solution is applicable can adopt a service-oriented architecture or a non-service-oriented architecture.

[0066] It is understandable that as the network evolves, the names of the aforementioned network elements may change, and the functions of the network elements may be merged, separated, or even changed. However, these changes do not mean that they are no longer within the scope of application of this application.

[0067] In wireless communication networks, XR technology offers advantages such as multi-view perspectives and strong interactivity, providing users with a completely new experience and possessing immense application value and commercial potential. XR encompasses technologies such as VR, AR, and MR, and can be widely applied in numerous fields including entertainment, gaming, healthcare, advertising, industry, online education, and engineering.

[0068] VR technology primarily refers to the rendering of visual and audio scenes to simulate the sensory stimulation of the user in the real world as closely as possible. In VR technology, users can wear XR terminals (such as head-mounted displays) to simulate visual and / or auditory experiences. VR technology can also track user movements to update the simulated visual and / or auditory content in real time. AR technology mainly refers to providing additional visual and / or auditory information or artificially generated content in the user's perceived real-world environment. The user's access to the real-world environment can be direct (e.g., without sensing, processing, or rendering) or indirect (e.g., transmitted through sensors), and further enhanced. MR technology inserts virtual elements into physical scenes to provide users with an immersive experience where these elements are part of the real scene. Network devices can process and transmit data generated by XR services (referred to as XR data). For example, cloud-based network devices can render and encode XR source data (e.g., source coding), and transmit XR data to XR terminals via core network and / or access network devices. XR terminals provide users with diverse XR experiences (such as immersive, visual, interactive, or device-based experiences) by processing XR data. XR experiences can be evaluated across various dimensions, including one or more of the following: image clarity, image smoothness, image distortion, image stereoscopic effect, black borders, image ghosting, sound quality, sound effects, field of view, stuttering, screen tearing, dizziness, audio-visual synchronization, freedom of interaction, response speed of interactive operations, accuracy of interactive operations, loading speed of interactive content, wearing comfort of the terminal, wearing fatigue of the terminal, battery life, portability, or visual impairment friendliness.

[0069] For the transmission of video services such as XR, video frames, or segments or fragments of video frames, can be sent to the terminal in the form of data packets. For example, video frames, or segments or fragments of video frames can be divided into Internet Protocol (IP) packets at the network transport layer and transmitted to the fixed network / core network. The IP data packets are then transmitted to the terminal via the wireless air interface. It is understood that the video frame in this application can also be referred to as a video frame or a data frame.

[0070] The characteristic of video frame, video frame strip, or video frame fragment transmission is that the multiple data packets contained in a video frame, strip, or fragment can be regarded as a whole. When a data packet is transmitted incorrectly, the entire video frame, video frame strip, or video frame fragment is also incorrect. The accuracy rate of video frames, video frame strips, or video frame fragments can typically measure the user experience of XR services; for example, a user experience at a 99% correct frame rate is generally good. The percentage of users meeting a given correct frame rate can measure the cell-level XR service experience performance; for example, a 95% user percentage achieving a 99% correct frame rate indicates a good cell-level XR service experience.

[0071] Current scheduling processes typically employ proportional fair (PF) scheduling. This involves the scheduler calculating a proportional fair factor for each terminal based on its current data transmission rate, historical rate characteristics, and the Quality of Service (QoS) class, and then scheduling terminals according to this factor. However, existing proportional fair scheduling methods prioritize maximizing system efficiency while ensuring terminal fairness, neglecting the integrity requirements of XR video frames, video frame striping, or video frame fragmentation. This leads to difficulties in meeting predetermined performance targets for XR service video frame accuracy and user satisfaction. Therefore, designing XR service transmission methods that improve the accuracy of XR video frames, video frame striping, or video frame fragmentation, as well as enhance user satisfaction within the cell, is a pressing issue that needs to be addressed.

[0072] The embodiments in this application provide an integrity transmission method for XR data transmission. In this method, data or information with synchronization requirements or dependencies are transmitted in an integrity manner to meet the synchronization needs between data or information, thereby improving the user experience of XR services.

[0073] In this application, the transmission of data with integrity can be understood as transmitting two or more video frames, video frame segments, or video frame strips as a whole. The object of integrity can be interpreted in several different ways.

[0074] For example, the object of integrity can be content, i.e., content integrity. Multiple pieces of content with different dimensions are related, therefore, the multiple data units corresponding to these multiple dimensions of content are transmitted with integrity. For instance, multiple data units corresponding to the content of a single frame are related; there is a relationship between the basic layer data units and enhancement layer data units corresponding to the content of a single frame; or there is a relationship between frame data units and audio data units, etc. Similarly, multiple data units corresponding to the content of a frame slice are related; or there is a relationship between the basic layer data units and enhancement layer data units corresponding to the content of a frame slice. Likewise, multiple data units corresponding to the content of a frame strip are related; or there is a relationship between the basic layer data units and enhancement layer data units corresponding to the content of a frame strip.

[0075] For example, the object of integrity can also be a task, event, object, or class; that is, task integrity, event integrity, object integrity, or class integrity. Multiple data units within the same task, event, object, or class have a relationship, thus requiring the integrity-based transmission of these multiple data units. For instance, in the tactile internet, multiple data units corresponding to video, audio, motion, and tactile information have a relationship; for example, the data packets corresponding to video and audio both belong to the tactile internet's data and are related.

[0076] It is understood that the data unit in this application may be a data packet, a video frame, a video frame fragment, or a video frame strip.

[0077] It is understood that the integrity transfer and integrity object in this application can also be described in other ways. For example, the above-mentioned integrity transfer can also be described as task-driven transfer, event-based transfer, or object-oriented transfer, etc., all of which are within the scope of this application.

[0078] The embodiments provided in this application are applicable to a variety of different scenarios. For example Figures 3-5 The illustrations show several scenarios in which the embodiments of this application can be applied.

[0079] Figure 3 A schematic diagram of a scenario to which an embodiment of this application applies is shown. Figure 3The diagram illustrates a system 300, comprising a server 310, a core network and access network 320 (which may be referred to as the transmission network 320, such as an LTE, 5G, or 6G network), and an XR terminal 330. The server 310 is used for encoding, decoding, and rendering XR source data; the transmission network 320 is used for transmitting XR data; and the XR terminal 330 provides users with diverse XR experiences through processing the XR data. It is understood that other devices may also be included between the transmission network 320 and the XR terminal 330, such as other terminals (e.g., mobile phones, laptops, or vehicles) and / or network devices (e.g., repeaters, WiFi routers, or WiFi access points). The XR terminal 330 obtains XR data from the transmission network 320 with the help of these other terminals and / or network devices.

[0080] Figure 4 A schematic diagram illustrating another scenario to which this application embodiment applies is shown. Figure 4 The diagram illustrates a system 400, comprising an XR terminal 430, a core network and access network 420 (which may be simply referred to as the transmission network 420, such as an LTE, 5G, or 6G network), and other terminals 410. Other terminals 410 are terminals other than the XR terminal 430; they can be either XR terminals or ordinary terminals (also referred to as non-XR terminals). Other terminals 410 can transmit data to the XR terminal 430 via the transmission network 420. For example, in a tactile internet, the XR terminal 430 could be a remotely controlled robot or remote operator in a controlled domain, while other terminals 410 could be tactile users and / or human-computer interface in the main domain. The other terminals 410 in the main domain transmit data to the XR terminal 430 in the controlled domain via the transmission network 420, thereby enabling remote control of the XR terminal 430.

[0081] Figure 5 A schematic diagram illustrating another scenario to which this application embodiment applies is shown. Figure 5 The diagram illustrates a system 500, which includes a server 510, a fixed network 520, a WiFi router or WiFi access point 530 (which may be referred to as a WiFi device 530), and an XR terminal 540. The server 510 can be used to encode, decode, and render XR source data, and transmit XR data to the XR terminal 540 via the fixed network 520 and the WiFi device 530.

Figure 6 This application illustrates the communication method using servers, core networks, wireless access network devices, and terminals as examples of the entities executing the interaction, but it does not limit the entities executing the interaction. For example, Figure 6 The server in the diagram can also be a chip, chip system, or processor that supports the implementation of this method on the server.

Figure 6 The illustrated method 600 includes parts 610 to 640. This method enables the complete transmission of data or information with synchronization requirements or dependencies, satisfying the synchronization needs between data or information, thereby improving the user experience of XR services. The method 600 provided in this application embodiment is described below.

[0084] Section 610: Service characteristic configuration information of data obtained by the wireless access network device. Optionally, the above data corresponds to the data of a video frame, the data of the same segment within a video frame, or the data of the same strip within a video frame. The aforementioned video frame segmentation or video frame striping refers to the fact that video frames can be encoded according to regional divisions during encoding, and the divided regions are called video frame segments or video frame stripes. In this way, the wireless access network device can identify the XR service type and the integrity transmission requirements of the XR service. It is understood that the embodiments of this application do not limit the specific name of the integrity transmission requirement; integrity transmission requirement is merely a possible name, and any other requirement name that can reflect the above function should be understood as the integrity transmission requirement in the solution of this application. When the data has the above-mentioned integrity transmission requirement, the data information contained in the data will be treated as a whole and transmitted on the wireless access network device side, thereby supporting the integrity transmission of the data on the wireless access network device and improving the user experience of the XR service.

[0085] In one possible implementation of section 610, service feature configuration information can be configured by a core network element (e.g., an SMF element) to the radio access network device. The radio access network device obtains this service feature configuration information based on the configuration of the core network element. Optionally, the core network obtains the service type of the transmitted data through a server notification, for example, the server notifies the core network that the current service type is XR service. In this way, the radio access network device can identify and receive the service feature configuration information corresponding to the aforementioned data.

[0086] In one possible implementation of the aforementioned service feature configuration information, the service feature configuration information indicates the service type information and / or integrity information of the data. The service type information indicates the service type to which the data belongs (e.g., XR service). The integrity information may indicate one or more of the following: whether multiple data packets belong to a single entity; whether multiple data packets need to be transmitted as a single entity; the frame information, frame strip information, or frame fragment information to which the multiple data packets belong; and the data size information of the frame, frame strip, or frame fragment to which the multiple data packets belong, such as data size or number of data packets. Through this implementation, the wireless access network device can identify the XR service type and enable data from the same frame, the same fragment, or the same strip to be transmitted as a single entity, thereby improving the user's experience with the video feed.

[0087] In one possible implementation of the aforementioned service feature configuration information, the service feature configuration information includes one or more of the following: 5G Quality of Service Identity (5QI) information, Quality of Service Flow Identifier (QFI) information, Quality of Service Profile information, bearer information, or General Packet Radio Service Tunneling Protocol (GTP) information, used to indicate the service type information and / or integrity information of the aforementioned data. This implementation enables the aforementioned service feature configuration information to be received and identified, thereby supporting the integrity transmission of data in the radio access network equipment and improving the user experience of XR services.

[0088] For example, the service type information indicated by the service characteristic configuration information can be carried by the service type information attribute in the 5QI information, QFI information, quality of service template information or GTP information, or it can be implemented by the core network by configuring the corresponding bearer information, 5QI information or QFI information for the corresponding service.

[0089] As shown in Table 1, the core network can configure corresponding bearer information for each service. In the example in Table 1, bearer 1, bearer 2, and bearer 3 correspond to voice service, video service, and XR service, respectively.

[0090] Table 1

[0091] Bearing Business type Carry 1 Voice services Carry 2 Video services Carry 3 XR services

[0092] As shown in Table 2, the core network can configure corresponding 5QI for each service. In the example in Table 2, 5QI1, 5QI2, and 5QI3 correspond to voice services, video services, and XR services, respectively.

[0093] Table 2

[0094] 5QI Business type 5QI1 Voice services 5QI2 Video services 5QI3 XR services

[0095] As shown in Table 3, the core network can configure corresponding QFIs for the respective services. In the example in Table 3, QFI1, QFI2, and QFI3 correspond to voice services, video services, and XR services, respectively.

[0096] Table 3

[0097]

[0098]

[0099] Through the above methods, wireless access network devices can obtain the service type information corresponding to the above data.

[0100] For example, the integrity information indicated by the service feature configuration information can be carried by the integrity information attribute in the 5QI information, QFI information, quality of service template information or GTP information, or the core network can implement it by configuring the corresponding bearer information, 5QI information or QFI information for the integrity information attribute.

[0101] As shown in Table 4, the core network can configure corresponding bearer information for integrity information attributes. In the example in Table 4, bearer 4 and bearer 5 correspond to those requiring integrity transmission and those not requiring integrity transmission, respectively.

[0102] Table 4

[0103] Bearing Integrity information attribute (whether integrity transmission is required) Carry 4 yes Carry 5 no

[0104] As shown in Table 5, the core network can configure corresponding 5QIs for integrity information attributes. In the example in Table 5, 5QI4 and bearer 5QI5 correspond to the requirement for integrity transmission and the requirement for no integrity transmission, respectively.

[0105] Table 5

[0106] 5QI Integrity information attribute (whether integrity transmission is required) 5QI4 yes 5QI5 no

[0107] As shown in Table 6, the core network can configure corresponding QFIs for integrity information attributes. In the example in Table 6, QFI4 and bearer QFI5 correspond to the requirement for integrity transmission and the requirement for no integrity transmission, respectively.

[0108] Table 6

[0109] QFI value Integrity information attribute (whether integrity transmission is required) QFI4 yes QFI5 no

[0110] In this way, wireless access network devices can obtain the integrity information of the services corresponding to the aforementioned data.

[0111] In another possible implementation of section 610, the service characteristic configuration information of the data is determined by sensing the data volume and periodicity. For example, when it is sensed that the data arrives periodically and the data volume is greater than a first threshold (e.g., the data volume is greater than 1 megabit), it can be determined that the service type of the data is an XR service type.

[0112] Section 620: The wireless access network equipment configures the data to be transmitted based on service characteristics, configuration information, and untransmitted and / or transmitted data. This method ensures complete transmission of XR data, thereby improving the accuracy of XR video frame transmission, the overall user satisfaction rate of the cell, and enhancing the user experience of XR services.

[0113] In one possible implementation of section 620, the wireless access network device prioritizes data to be transmitted based on untransmitted data and / or transmitted data. This implementation optimizes data transmission priority based on the relevance of video frames, video segments, or video strips, thereby improving the user experience with XR data.

[0114] In one possible implementation of priority setting, the priority factor set for the data packet to be transmitted corresponds to the amount of transmitted data and the amount of remaining data in the currently transmitted video frame. This correspondence, for example, satisfies function f1:

[0115]

[0116] Here, "all data" represents the total data volume of the currently transmitted video frame, i.e., all data = sent data + remaining data. It can be understood that the data volume in this application can refer to the number of data packets or other data volume parameters. For example, f1 satisfies:

[0117]

[0118] That is, there is a linear relationship between the priority factor set on the data packet to be transmitted and the ratio of the amount of transmitted data (sent data) of the current transmitted video frame to the total amount of data (all data), where α is a non-zero real number.

[0119] In another possible implementation of priority setting, the priority factor set for the data packet to be transmitted corresponds to the amount of data already transmitted in the currently transmitted video frame. This correspondence, for example, satisfies function f2:

[0120] factor = f2(sent data)

[0121] For example, f2 satisfies:

[0122] factor = α × (sent data)

[0123] That is, the priority factor set for the data packet to be transmitted has a linear proportional relationship with the amount of data already transmitted in the current video frame.

[0124] In another possible implementation of priority setting, the priority factor set for the data packet to be transmitted corresponds to the amount of untransmitted data in the currently transmitted video frame. This correspondence, for example, satisfies function f3:

[0125] factor = f3(remaining data)

[0126] For example, f3 satisfies:

[0127] factor = α × (remaining data)

[0128] That is, the priority factor set for the data packets to be transmitted has a linear proportional relationship with the amount of untransmitted data in the currently transmitted video frame.

[0129] Optionally, in the above-described priority setting method, in addition to considering untransmitted data and / or transmitted data, other factors can also be considered when prioritizing data to be transmitted. In one possible implementation, the wireless access network device prioritizes data to be transmitted based on one or more of the following: the amount of untransmitted data and / or transmitted data, the transmission latency of transmitted data, the estimated transmission latency of untransmitted data, the correct reception rate of transmitted data, the instantaneous transmission rate, or the historical transmission rate. This implementation method allows for optimization of data transmission priority based on the relevance of video frames, video segments, or video strips, thereby improving the user's experience with XR data.

[0130] In one possible implementation of priority setting, the priority factor set for the data packet to be transmitted corresponds to the amount of data already transmitted, the amount of data not yet transmitted, and the estimated transmission delay of the remaining data in the current video frame. This correspondence, for example, satisfies function f4:

[0131]

[0132] Where delay represents the transmission delay of the current video frame, or it can be the estimated transmission delay based on the remaining data of the current video frame, for example, satisfying the following functional relationship: Where R_his represents the historical rate of the current user or the historical rate of the current user's current transmitted frame. For example, f5 satisfies: That is, the transmission delay of the current video frame or the estimated transmission delay of the remaining data of the current video frame is a linear function of the ratio of the amount of untransmitted data of the current video frame to the historical rate of the current user's current transmission frame, where μ is a non-zero real number.

[0133] For example, f4 satisfies:

[0134]

[0135] That is, the priority factor set of the data packet to be transmitted has a linear proportional relationship with the ratio of the amount of transmitted data (sent data) and the total amount of data (all data) of the currently transmitted video frame, as well as the delay of the currently transmitted video frame, where β is a non-zero real number.

[0136] In one possible implementation of priority setting, the priority factor set for the data packets to be transmitted corresponds to the amount of data already transmitted, the amount of data not yet transmitted, the estimated transmission delay of the remaining data in the current transmitted video frame, and the historical correct frame rate obtained by the wireless access network device. This correspondence, for example, satisfies function f6:

[0137]

[0138] FTR represents the historical correct frame rate obtained by the wireless access network device.

[0139] For example, f6 satisfies:

[0140]

[0141] The priority factor of the data packet to be transmitted has a linear proportional relationship with the ratio of the amount of transmitted data (sent data) to the total amount of data (all data) of the currently transmitted video frame, the latency of the currently transmitted video frame, and the historical correct frame rate, where γ is a non-zero real number.

[0142] In one possible implementation of priority setting, the priority factor set for the data packet to be transmitted corresponds to the amount of data already transmitted, the amount of data not yet transmitted, the estimated transmission delay of the remaining data in the current transmitted video frame, the historical correct frame rate obtained by the wireless access network device, and the instantaneous transmission rate of the current user. This correspondence, for example, satisfies function f7:

[0143]

[0144] R_ins represents the instantaneous rate of the currently scheduled user at the current moment.

[0145] For example, f7 satisfies:

[0146]

[0147] The priority factor set for the data packet to be transmitted has a linear proportional relationship with the ratio of the amount of transmitted data (sent data) to the total amount of data (all data) of the currently transmitted video frame, the latency of the currently transmitted video frame, the historical correct frame rate, and the instantaneous rate of the currently scheduled user, where δ is a non-zero real number.

[0148] In one possible implementation of priority setting, the priority factor set for the data packet to be transmitted corresponds to the amount of data already transmitted, the amount of data not yet transmitted, the estimated transmission delay of the remaining data in the current transmitted video frame, the historical correct frame rate obtained by the wireless access network device, the current user's instantaneous transmission rate, and the historical transmission rate. This correspondence, for example, satisfies function f8:

[0149]

[0150] R_his represents the historical rate of the current user or the historical rate of the current user's current transmitted frame.

[0151] For example, f8 satisfies:

[0152]

[0153] The priority factor of the data packet to be transmitted has a linear proportional relationship with the ratio of the amount of transmitted data (sent data) to the total amount of data (all data) of the currently transmitted video frame, the latency of the currently transmitted video frame, the historical correct frame rate, the instantaneous rate of the currently scheduled user, and the historical rate of the current user or the historical rate of the current transmitted frame of the current user, where ε is a non-zero real number.

[0154] In one possible implementation of priority setting, the priority factor set for the data packets to be transmitted corresponds to the amount of data already transmitted, the amount of data not yet transmitted, the current user's instantaneous transmission rate, and the historical transmission rate of the currently transmitted video frame. This correspondence, for example, satisfies function f9:

[0155]

[0156] For example, f9 satisfies:

[0157]

[0158] That is, the priority factor set for the data packet to be transmitted has a linear proportional relationship with the ratio of the amount of transmitted data (sent data) to the total amount of data (all data) of the currently transmitted video frame, the latency, the historical correct frame rate, the instantaneous rate of the currently scheduled user, and the historical rate of the current user or the historical rate of the current transmitted frame of the current user.

[0159] In one possible implementation of priority setting, the priority factor set for the data packet to be transmitted corresponds to the amount of data already transmitted, the amount of data not yet transmitted, the estimated transmission delay of the remaining data in the current video frame, the current user's instantaneous transmission rate, and the historical transmission rate. This correspondence, for example, satisfies function f10:

[0160]

[0161] For example, f10 satisfies:

[0162]

[0163] That is, the priority factor set for the data packet to be transmitted has a linear proportional relationship with the ratio of the amount of transmitted data (sent data) to the total amount of data (all data) of the currently transmitted video frame, the latency of the currently transmitted video frame, the instantaneous rate of the currently scheduled user, and the historical rate of the current user or the historical rate of the current transmitted frame of the current user.

[0164] In one possible implementation of priority setting, the priority factor set for the data packet to be transmitted corresponds to the amount of data already transmitted in the currently transmitted video frame and the estimated transmission delay of the remaining data in the currently transmitted video frame. This correspondence, for example, satisfies function f11:

[0165] factor=f11(sent data, delay)

[0166] For example, f11 satisfies:

[0167] factor=α×sent data+β×delay

[0168] That is, the priority factor set for the data packet to be transmitted has a linear proportional relationship with the amount of data sent in the currently transmitted video frame and the delay of the currently transmitted video frame.

[0169] In one possible implementation of priority setting, the priority factor set for the data packets to be transmitted corresponds to the amount of data already transmitted in the currently transmitted video frame, the current user's instantaneous transmission rate, and the historical transmission rate. This correspondence, for example, satisfies function f12:

[0170] factor=f12(sent data,R_ins,R_his)

[0171] For example, f12 satisfies:

[0172] factor=α×sent data+β×R_ins+γ×R_his

[0173] That is, the priority factor set for the data packet to be transmitted has a linear proportional relationship with the amount of data sent in the current video frame, the instantaneous rate of the current scheduling user, and the historical rate of the current user or the historical rate of the current transmission frame of the current user.

[0174] In one possible implementation of priority setting, the priority factor set for the data packet to be transmitted corresponds to the amount of data already transmitted in the currently transmitted video frame, the estimated transmission delay of the remaining data in the currently transmitted video frame, and the instantaneous transmission rate of the current user. This correspondence, for example, satisfies function f13:

[0175] factor=f13(sent data,delay,R_ins)

[0176] For example, f13 satisfies:

[0177] factor=α×sent data+β×delay+γ×R_ins

[0178] That is, the priority factor set for the data packet to be transmitted has a linear proportional relationship with the amount of data sent in the currently transmitted video frame, the latency of the currently transmitted video frame, and the instantaneous rate of the currently scheduled user.

[0179] In one possible implementation of priority setting, the priority factor set for the data packet to be transmitted corresponds to the amount of data already transmitted in the currently transmitted video frame, the estimated transmission delay of the remaining data in the currently transmitted video frame, the instantaneous transmission rate of the current user, and the historical transmission rate. This correspondence, for example, satisfies function f14:

[0180] factor=f14(sent data,delay,R_ins,R_his)

[0181] For example, f14 satisfies:

[0182] factor=α×sent data+β×delay+γ×R_ins+δ×R_his

[0183] That is, the priority factor set for the data packet to be transmitted has a linear proportional relationship with the amount of data sent in the currently transmitted video frame, the delay of the currently transmitted video frame, the instantaneous rate of the currently scheduled user, and the historical rate of the current user or the historical rate of the current transmitted frame of the current user.

[0184] In another possible implementation of section 620, the wireless access network device prioritizes data transmission based on the estimated transmission delay of the remaining data for the currently transmitted video frame. This implementation optimizes data transmission priority based on the relevance of video frames, video segments, or video strips, thereby improving the user experience with XR data. The longer the estimated transmission delay of the remaining data for the currently transmitted video frame, the higher the scheduling priority; that is, the delay factor carries more weight in determining the scheduling priority. The scheduling priority factor for the current user data packet is a monotonically increasing function of the estimated remaining transmission delay. In this way, when resources are relatively unconstrained, users with relatively poor channel conditions can be served with complete transmission as quickly as possible (at the expense of scheduling opportunities for users with better channel conditions), thereby improving the accuracy of user frame transmission and enhancing overall user satisfaction.

[0185] In one possible implementation of priority setting, the priority factor set for the data packet to be transmitted corresponds to the estimated transmission delay of the remaining data in the currently transmitted video frame. This correspondence, for example, satisfies function f15:

[0186] factor = f15(delay)

[0187] For example, f15 satisfies:

[0188] factor=α×delay

[0189] That is, the priority factor set for the data packet to be transmitted has a linear proportional relationship with the latency of the currently transmitted video frame.

[0190] Optionally, in the above-described priority setting method, in addition to considering the estimated transmission delay of the remaining data of the currently transmitted video frame, other factors can also be considered when prioritizing the data to be transmitted. In one possible implementation, the wireless access network device prioritizes the data to be transmitted based on one or more of the following: the estimated transmission delay of the remaining data of the currently transmitted video frame, the current user's instantaneous transmission rate, and historical transmission rates. This implementation method allows for optimization of data transmission priority based on the correlation between video frames, video segments, or video strips, thereby improving the user's experience with XR data.

[0191] In one possible implementation of priority setting, the priority factor set for the data packets to be transmitted corresponds to the estimated transmission delay of the remaining data in the currently transmitted video frame and the instantaneous transmission rate of the current user. This correspondence, for example, satisfies function f16:

[0192] factor = f16(delay, R_ins)

[0193] For example, f16 satisfies:

[0194] factor=α×delay+β×R_ins

[0195] That is, the priority factor set for the data packet to be transmitted has a linear proportional relationship with the latency of the currently transmitted video frame and the instantaneous rate of the currently scheduled user.

[0196] In one possible implementation of priority setting, the priority factor set for the data packets to be transmitted corresponds to the estimated transmission delay of the remaining data in the currently transmitted video frame, the current user's instantaneous transmission rate, and the historical transmission rate. This correspondence, for example, satisfies function f17:

[0197] factor=f17(delay, R_ins, R_his)

[0198] For example, f17 satisfies:

[0199] factor=α×delay+β×R_ins+γ×R_his

[0200] That is, the priority factor set for the data packet to be transmitted has a linear proportional relationship with the delay of the current transmitted video frame, the instantaneous rate of the current scheduled user, and the historical rate of the current user or the historical rate of the current transmitted frame of the current user.

[0201] In another possible implementation of section 620, the wireless access network device does not transmit data units containing data to be transmitted, depending on whether the data has not been transmitted and / or has already been transmitted. This implementation reduces data transmission that does not contribute to the XR data experience, thereby reducing waste of transmission resources and improving the efficiency of transmission resource utilization.

[0202] In one possible implementation of a data unit that does not transmit data to be transmitted, the wireless access network device does not transmit the data unit when there is an error in the transmitted data, or when the estimated transmission time for the untransmitted data exceeds a transmission time threshold, or when the correct reception rate of the transmitted data is less than a correct reception rate threshold. This implementation reduces data transmission that does not contribute to the XR data experience, thereby reducing the waste of transmission resources and improving the efficiency of transmission resource utilization.

[0203] For example, if a wireless access network device determines, based on feedback from a terminal, that a data packet for a certain video frame is in a state of transmission error (e.g., it still fails to transmit successfully after reaching the maximum number of retransmissions), the wireless access network device will not send the remaining data packets corresponding to the erroneous video frame. This reduces the data transmission that does not contribute to the XR data experience, thereby reducing the waste of transmission resources and improving the efficiency of transmission resource utilization.

[0204] For example, the wireless access network device estimates the remaining data packet transmission time of the current video frame based on historical data rates. If the estimated remaining data packet transmission time of the current video frame is greater than a given time threshold, the wireless access network device will not send the remaining data packets of the erroneous video frame. This reduces data transmission that does not contribute to the XR data experience, thereby reducing the waste of transmission resources and improving the efficiency of transmission resource utilization.

[0205] For example, the wireless access network device determines whether the current user's historical correct frame rate is less than a given threshold (e.g., 50%) based on statistically analyzed historical correct frame rates. If it is less than the given threshold, the wireless access network device does not send the remaining data packets of the erroneous video frames, thereby reducing data transmission that does not contribute to the XR data experience, reducing waste of transmission resources, and improving the efficiency of transmission resource utilization. Optionally, the correct frame rate of the service can be used as a benchmark; if the benchmark is less than a certain threshold, the remaining data packets of the service will no longer be sent. Alternatively, the correct frame rate can be periodically checked, and if the correct frame rate is less than a certain threshold, the remaining data packets of the service will no longer be sent.

[0206] Part 630: Wireless access network devices communicate with terminals based on the configuration of the data to be transmitted.

[0207] In one possible implementation of section 630, the communication between the radio access network device and the terminal based on the configuration of the data to be transmitted includes: sending the data to be transmitted to the terminal according to the configuration of the data to be transmitted. For example, the radio access network device sends the data to be transmitted to the terminal via a data channel according to the configuration of the data to be transmitted. As another example, the radio access network device sends configuration parameters or control information related to the data to be transmitted to the terminal via a control channel. In this way, the terminal can identify and receive XR service data from the radio access network device.

[0208] In one possible implementation of part 630, the wireless access network device communicating with a terminal based on the configuration of data to be transmitted includes: sending transmission indication information of the data to be transmitted to the terminal, the transmission indication information being used for processing transmitted data. Optionally, the transmission indication information indicates data integrity transmission criteria, the number of data packets contained in the data to be transmitted, and the data unit to which the data packets of the data to be transmitted belong. Optionally, the transmission indication information is used to indicate the data unit to which data packets to be transmitted that are not transmitted belong.

[0209] The aforementioned transmission indication information can be carried by radio resource control (RRC) messages, downlink control information (DCI), or media access control control element (MAC CE). For example, a radio access network (RAN) device may use an RRC message to notify a terminal of the integrity transmission criteria for the current service, the number of data packets contained in the data to be transmitted, the data unit to which the data packets to be transmitted belong, and the data unit to which the data packets to be untransmitted belong. Alternatively, the RAN device may use an RRC message to notify a terminal of the integrity transmission criteria for the current service, and use DCI or MAC CE to indicate the number of data packets contained in the data to be transmitted, the data unit to which the data packets to be transmitted belong, and the data unit to which the data packets to be untransmitted belong. Again, the RAN device may use DCI or MAC CE to indicate the integrity transmission criteria, the number of data packets contained in the data to be transmitted, the data unit to which the data packets to be transmitted belong, and the data unit to which the data packets to be untransmitted belong. This method indicates the integrity transmission criteria for the current service type, the number of data packets contained in the data to be transmitted, the data unit to which the data packets to be transmitted belong, and / or the data unit to which the data packets to be transmitted belong, thereby supporting the integrity transmission requirements of XR video frames and improving the user experience of XR services.

[0210] In one possible implementation of section 630, the terminal receives transmission indication information from the radio access network device and performs data integrity reception based on the transmission indication information. This method enables integrity reception tailored to the service characteristics of XR video services, improving the accuracy of XR data packets and the satisfaction rate of cell users, thereby enhancing the user experience of XR services.

[0211] In one possible implementation of receiving data with integrity based on the aforementioned transmission indication information, the terminal determines the data packets received in the current frame. If there are any data packets with reception errors, the terminal clears the data packets of the current received frame, including both successfully decoded and undecoded data packets. By clearing all or part of the data packets in the erroneous video frame in this way, the transmission of data that does not contribute to the XR data experience can be reduced, thereby reducing the waste of transmission resources and improving the efficiency of transmission resource utilization.

[0212] In another possible implementation of receiving data with integrity based on the aforementioned transmission indication information, when the terminal learns from the transmission indication information that packet loss has occurred in the wireless access network device, it clears all data packets of the currently received frame, including both successfully decoded and undecoded data packets. By clearing all or part of the data packets in the erroneous video frame in this way, data transmission that does not contribute to the XR data experience can be reduced, thereby reducing the waste of transmission resources and improving the efficiency of transmission resource utilization.

[0220] Optionally, the device 700 in this application embodiment can be used to perform the actions described in this application embodiment. Figure 6 The method described in [the document / document].

[0229] Figure 8 A schematic diagram of a terminal device is provided. This terminal device is applicable to... Figure 1 , Figure 2 , Figure 3 , Figure 4 or Figure 5 In the scenario shown. For ease of explanation, Figure 8 Only the main components of the terminal device are shown. For example... Figure 8 As shown, the terminal device 800 includes a processor, memory, control circuitry, antenna, and input / output devices. The processor is primarily used for processing communication protocols and data, controlling the entire terminal, executing software programs, and processing software program data. The memory is primarily used for storing software programs and data. The radio frequency (RF) circuitry is primarily used for converting baseband signals to RF signals and processing RF signals. The antenna is primarily used for transmitting and receiving RF signals in the form of electromagnetic waves. Input / output devices, such as touchscreens, displays, and keyboards, are primarily used for receiving user input data and outputting data to the user.

[0230] When the terminal device is powered on, the processor can read the software program from the storage unit, parse and execute the instructions of the software program, and process the data of the software program. When data needs to be transmitted wirelessly, the processor performs baseband processing on the data to be transmitted and outputs the baseband signal to the radio frequency (RF) circuit. The RF circuit processes the baseband signal to obtain the RF signal and transmits the RF signal outward in the form of electromagnetic waves through the antenna. When data is sent to the terminal device, the RF circuit receives the RF signal through the antenna. This RF signal is further converted into a baseband signal and output to the processor. The processor converts the baseband signal back into data and processes the data.

[0231] For ease of explanation, Figure 8 Only one memory and processor are shown. In actual terminal devices, multiple processors and memories may exist. Memory can also be called storage medium or storage device, etc., and this embodiment of the invention does not limit this.

[0232] As an optional implementation, the processor may include a baseband processor and a central processing unit (CPU). The baseband processor is mainly used to process communication protocols and communication data, while the CPU is mainly used to control the entire terminal device, execute software programs, and process the data of the software programs.

Those skilled in the art will understand that the baseband processor and CPU can also be independent processors interconnected via technologies such as buses. It will also be understood that a terminal device can include multiple baseband processors to adapt to different network standards, and multiple CPUs to enhance its processing capabilities. The various components of the terminal device can be connected via various buses. The baseband processor can also be described as a baseband processing circuit or a baseband processing chip. Similarly, the CPU can be described as a central processing circuit or a central processing chip. The function of processing communication protocols and communication data can be built into the processor or stored as a software program in a storage unit, with the processor executing the software program to implement the baseband processing function.

[0233] In one example, the antenna and control circuit with transceiver functions can be considered as the transceiver unit 811 of the terminal device 800, and the processor with processing functions can be considered as the processing unit 812 of the terminal device 800. For example... Figure 8 As shown, the terminal device 800 includes a transceiver unit 811 and a processing unit 812. The transceiver unit can also be referred to as a transceiver, transceiver device, or transceiver apparatus. Optionally, the device in the transceiver unit 811 used for receiving functions can be considered a receiving unit, and the device in the transceiver unit 811 used for transmitting functions can be considered a transmitting unit; that is, the transceiver unit 811 includes both a receiving unit and a transmitting unit. For example, the receiving unit can also be referred to as a receiver, receiver circuit, or receiving device, and the transmitting unit can be referred to as a transmitter, transmitter, or transmitting circuit. Optionally, the receiving unit and the transmitting unit can be integrated into a single unit or can be multiple independent units.
