Description

An information reporting method and communication device

[0001] This application claims priority to Chinese Patent Application No. 202410925603.6, filed on July 10, 2024, entitled "An Information Reporting Method and Communication Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communications, and more particularly to an information reporting method and a communication device. Background Technology

[0003] With the continuous advancement of technology, human-computer interaction methods are constantly evolving and innovating. In the past, computers and humans primarily interacted through keyboards and mice. However, multimodal applications are now emerging, integrating various interaction methods such as voice, images, and gestures to bring users a richer and more natural experience. Multimodal applications refer to applications that utilize multiple interaction methods to communicate and interact with computer systems. These interaction methods can include voice, images, gestures, touch, and speech. The goal of multimodal applications is to achieve a more intelligent, natural, and efficient user experience, enabling users to communicate with computers more intuitively.

[0004] For immersive multimodal virtual reality (VR) applications, data stream synchronization between different media components is crucial to avoid negatively impacting the user experience (i.e., viewers detecting a lack of synchronization). However, current data stream synchronization methods are still inadequate, resulting in high signaling overhead. Therefore, improving the synchronization between data streams while reducing signaling overhead during data transmission is a pressing issue that needs to be addressed. Summary of the Invention

[0005] This application provides an information reporting method and communication device. Based on the method described in this application, it is beneficial to improve the synchronization between data streams and reduce signaling overhead.

[0006] In a first aspect, this application provides an information reporting method, the method comprising: receiving first information from a network device, the first information being used to determine a first threshold and / or a second threshold; and sending first indication information to the network device, the first indication information being determined based on the first threshold and / or the second threshold.

[0007] In the embodiments of this application, the method described in the first aspect can be applied to a terminal device. The network device can configure one or more thresholds (such as a first threshold and / or a second threshold) to the terminal device via first information, so that the terminal device can monitor information such as the asynchronous state or the amount of asynchronous data between different data streams. For example, the first threshold here can be a time-related threshold used to determine whether different data streams are in an asynchronous state; the second threshold here can be a data volume-related threshold used to determine whether the amount of asynchronous data between different data streams exceeds the second threshold. When the terminal device detects through these thresholds that the current different data streams are in an asynchronous state and / or the amount of asynchronous data between different data streams exceeds the second threshold, it will trigger the terminal device to report first indication information to the network device to inform the network device of the urgency of increasing uplink transmission resources. This allows the network device to quickly configure transmission resources (i.e., second transmission resources) for the terminal device according to the first indication information, ensuring that these asynchronous data can be prioritized for scheduling or transmission, thereby ensuring that the time difference between different data streams is within the threshold index, and thus improving the synchronization between different data streams. In addition, since the terminal device only reports the first indication information (e.g., it can occupy 1 bit), that is, it only indicates that the current different data streams are in an asynchronous state and / or the amount of asynchronous data exceeds the threshold, and does not directly report the amount of asynchronous data between different data streams, it also reduces the signaling overhead and reduces the reporting latency to a certain extent.

[0008] In one possible implementation, the first information is used to determine a first threshold; if the first time difference between the first data stream and the second data stream is greater than or equal to the first threshold, then the first indication information is used to indicate that the first data stream and the second data stream are in an asynchronous state.

[0009] Based on this approach, the first threshold is used to determine whether different data streams are out of sync. Taking the first and second data streams as examples, when the first time difference between the first and second data streams is greater than or equal to the first threshold, they are considered out of sync. In this case, a first indication message can be sent to the network device to notify it to allocate transmission resources as soon as possible, thereby improving the synchronization between the data streams. When the first time difference between the first and second data streams is less than the first threshold, they are considered synchronized. In this case, the terminal device can continue monitoring without reporting.

[0010] In one possible implementation, the first threshold includes a first value and / or a second value; the first value and the second value may be the same or different.

[0011] When the first threshold is a first value, the first time difference is the time difference between the first data stream and the second data stream, and the first indication information is used to indicate that the first data stream is out of sync with the second data stream; when the first threshold is a second value, the first time difference is the time difference between the second data stream and the first data stream, and the first indication information is used to indicate that the second data stream is out of sync with the first data stream.

[0012] Based on this approach, the first and second data streams are directional; that is, the first time difference between them can be either the time difference between the first and second data streams relative to the second data stream, or the time difference between the second and first data streams relative to the first data stream. For data streams of different business types, the first threshold can be set the same or different under different circumstances, thereby improving the flexibility of the first threshold.

[0013] In one possible implementation, the first information is further used to determine a second threshold; if the first data volume corresponding to the first time difference being greater than or equal to the first threshold is greater than or equal to the second threshold, then the first indication information is used to indicate that the amount of asynchronous data between the first data stream and the second data stream is greater than or equal to the second threshold.

[0014] Based on this approach, the second threshold can be a threshold related to the data volume, used to determine whether the amount of asynchronous data between different data streams exceeds this second threshold. Taking the first and second data streams as examples, when the amount of asynchronous data between the first and second data streams is greater than or equal to the second threshold, a report can be sent to the network device via the first indication information to notify the network device to allocate transmission resources as soon as possible, thereby improving the synchronization between the data streams. When the amount of asynchronous data between the first and second data streams is less than the second threshold, the terminal device can continue monitoring without reporting. In this way, the network device can know whether the amount of asynchronous data between different data streams is greater than or equal to the second threshold, and based on the size of the second threshold, it can estimate the size of the asynchronous data, thus facilitating the network device to allocate transmission resources to the terminal device.

[0015] In one possible implementation, the first information is further used to determine a second threshold; if the ratio of the first data volume to the first transmission resource corresponding to the first time difference being greater than or equal to the first threshold is greater than or equal to the second threshold, then the first indication information is used to indicate the ratio.

[0016] Based on this approach, the second threshold can be a ratio-related threshold to determine whether the ratio of the asynchronous data volume between different data streams to the first transmission resource exceeds the second threshold. Taking the first and second data streams as examples, when the ratio of the asynchronous data volume between the first and second data streams to the first transmission resource is greater than or equal to the second threshold, the ratio can be reported to the network device via the first indication information to notify the network device to allocate transmission resources as soon as possible, thereby improving the synchronization between data streams. When the ratio of the asynchronous data volume between the first and second data streams to the first transmission resource is less than the second threshold, the terminal device can continue monitoring without reporting. In this way, the network device can know the ratio of the asynchronous data volume between different data streams to the first transmission resource. Based on the size of this ratio and the first transmission resource, the size of the asynchronous data volume can be deduced, thus facilitating the network device to configure transmission resources for the terminal device.

[0017] In one possible implementation, the first threshold includes a first value and / or a second value, the first value and the second value being the same or different; the second threshold includes a third value and / or a fourth value, the third value and the fourth value being the same or different.

[0018] When the first threshold is a first value and the second threshold is a third value, the first data volume is the data volume in the first data stream when the time difference between the first data stream and the second data stream is greater than or equal to the first value; when the first threshold is a second value and the second threshold is a fourth value, the first data volume is the data volume in the second data stream when the time difference between the second data stream and the first data stream is greater than or equal to the second value.

[0019] Based on this approach, the first and second data streams are directional; that is, the first time difference between them can be either the time difference between the first and second data streams relative to the second data stream, or the time difference between the second and first data streams relative to the first data stream. Similarly, the amount of asynchronous data between them can be either the amount of asynchronous data between the first and second data streams relative to the first data stream, or the amount of asynchronous data between the second and first data streams relative to the first data stream. For different types of business data streams, the first and second thresholds can be set the same or different under different circumstances, thereby improving the flexibility of the first threshold.

[0020] In one possible implementation, the first indication information is further used to indicate one or more of the following: an identifier of the service type corresponding to the first data stream, an identifier of the service type corresponding to the second data stream, an identifier of the service type pair, or an identifier of the logical channel group corresponding to the first transmission resource; wherein the service type pair indicates the service type corresponding to the first data stream and the service type corresponding to the second data stream.

[0021] In one possible implementation, the first information includes a first ratio; the first threshold is determined based on a first preset value and the first ratio. Based on this approach, the network device can configure the first threshold more flexibly.

[0022] In one possible implementation, the first information includes a second ratio; the second threshold is determined based on a second preset value and the second ratio. Based on this approach, network devices can configure the second threshold more flexibly.

[0023] In one possible implementation, the first threshold is related to one or more of the following: the service type corresponding to the first data stream, the service type corresponding to the second data stream, the data volume of the first data stream, or the data volume of the second data stream. Based on this approach, the first threshold can be set according to the service type and / or data volume corresponding to each data stream, which helps to save power consumption.

[0024] In one possible implementation, the first indication information is carried in any of the following: uplink control information (UCI), media access control unit (MAC CE), or scheduling request (SR).

[0025] In one possible implementation, the first information is carried in any of the following: downlink control information (DCI), MAC CE, or radio resource control (RRC).

[0026] In one possible implementation, the method further includes sending the first data volume to the network device.

[0027] Secondly, this application provides an information reporting method, which includes: sending first information to a terminal device, the first information being used to determine a first threshold and / or a second threshold; receiving first indication information from the terminal device, the first indication information being determined based on the first threshold and / or the second threshold; and configuring second transmission resources for the terminal device based on the first indication information.

[0028] In the embodiments of this application, the method described in the second aspect can be applied to network devices. The beneficial effects of possible implementations of the second aspect can be found in the beneficial effects of possible implementations of the first aspect, and will not be repeated here.

[0029] In one possible implementation, the first information is used to determine a first threshold; if the first time difference between the first data stream and the second data stream is greater than or equal to the first threshold, then the first indication information is used to indicate that the first data stream and the second data stream are in an asynchronous state.

[0032] In one possible implementation, the first information is further used to determine a second threshold; if the first data volume corresponding to the first time difference being greater than or equal to the first threshold is greater than or equal to the second threshold, then the first indication information is used to indicate that the amount of asynchronous data between the first data stream and the second data stream is greater than or equal to the second threshold.

[0033] In one possible implementation, the first information is further used to determine a second threshold; if the ratio of the first data volume to the first transmission resource corresponding to the first time difference being greater than or equal to the first threshold is greater than or equal to the second threshold, then the first indication information is used to indicate the ratio.

[0034] In one possible implementation, the first threshold includes a first value and / or a second value, the first value and the second value being the same or different; the second threshold includes a third value and / or a fourth value, the third value and the fourth value being the same or different.

[0035] When the first threshold is a first value and the second threshold is a third value, the first data volume is the data volume in the first data stream when the time difference between the first data stream and the second data stream is greater than or equal to the first value; when the first threshold is a second value and the second threshold is a fourth value, the first data volume is the data volume in the second data stream when the time difference between the second data stream and the first data stream is greater than or equal to the second value.

[0038] In one possible implementation, the first information includes a second ratio; the second threshold is determined based on a second preset value and the second ratio.

[0039] In one possible implementation, the first threshold is related to one or more of the following: the business type corresponding to the first data stream, the business type corresponding to the second data stream, the data volume of the first data stream, or the data volume of the second data stream.

[0041] In one possible implementation, the first information is carried in any of the following: DCI, MACCE, or RRC.

[0067] I. Terminal Equipment

[0068] The terminal device mentioned in the embodiments of this application can be a device with wireless transceiver capabilities. The terminal device can communicate with access network equipment (or access devices or network devices) in a radio access network (RAN). The terminal device can also be referred to as user equipment (UE), access terminal, terminal, subscriber unit, user station, mobile station, remote station, remote terminal, mobile device, user terminal, user agent, or user device, etc. In one possible implementation, the terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; or it can be deployed on water, including ships; or it can be deployed in the air, such as on airplanes, balloons, or satellites. In another possible implementation, the terminal device can be a handheld device with wireless communication capabilities, vehicle-mounted device, wearable device, sensor, terminal in the Internet of Things, terminal in the Internet of Vehicles, drone, 5G network, or any form of terminal device in future networks, etc., and this application embodiment does not limit this. In another possible implementation, the terminal device can also be a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in autonomous driving, a wireless terminal in telemedicine, a wireless terminal in a smart grid, a wireless terminal in a smart city, or a wireless terminal in a smart home, etc.

[0069] In this application embodiment, the device for implementing the functions of the terminal device can be the terminal device itself; it can also be a device capable of supporting the terminal device in implementing the functions, such as a chip system. The device can be installed in the terminal device or used in conjunction with the terminal device. In this application embodiment, the chip system can be composed of chips or can include chips and other discrete devices. For ease of description, when examples are mentioned below, the technical solutions provided in this application embodiment are described using the UE as an example to illustrate the device for implementing the functions of the terminal device.

[0070] II. Network Equipment

[0071] A network device can be a device deployed in a radio access network to provide wireless communication services to terminal devices. This network device can also be called an access network device, access equipment, RAN node, or RAN equipment, etc. For example, a network device can be a base station, an evolved NodeB (eNodeB), a next-generation NodeB (gNB), a next-generation evolved NodeB (ng-eNB), or a network device in 6G communication, etc. A network device can be any device with wireless transceiver capabilities, including but not limited to the base stations mentioned above (including base stations deployed on satellites). This network device can also be a device with base station functionality in 6G. As an example, this network device can be an access node, wireless relay node, or wireless backhaul node in a wireless-fidelity (Wi-Fi) system. As another example, this network device can be a wireless controller in a cloud radio access network (CRAN) scenario. As yet another example, this network device can be a wearable device or in-vehicle device capable of providing wireless communication services, etc. As another example, the network device can also be a small station, a transmission reception point (TRP) (or a transmission point), etc. The network device can also be a master station, a secondary station, a motor slide retainer (MSR) node, a home base station, an access point (AP), a baseband unit (BBU), a remote radio unit (RRU), an active antenna unit (AAU), a remote radio head (RRH), a central unit (CU), a distributed unit (DU), a radio unit (RU), a positioning node, etc. In systems using different wireless access technologies, the names of devices with network device functions may vary; these will not be listed individually in the embodiments of this application.

[0072] Network devices can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile network device, and one or more cells can move according to the location of the mobile network device. In other examples, a helicopter or drone can be configured to be used as a device to communicate with another network device.

[0073] In some network device deployments, network devices can include centralized units (CUs) and distributed units (DUs). For example, some protocol layer functions of the network device may be centrally controlled by the CU, while the remaining partial or complete protocol layer functions may be distributed across the DU, which is then centrally controlled by the CU. In other network device deployments, the CU can be divided into CU-control plane (CP) and CU-user plane (UP). In still other deployments, the network device can also be an open radio access network (ORAN / O-RAN) architecture. When the network device is in an ORAN architecture, it can be a functional entity or module within the ORAN, such as a combination of one or more of the following: CU, DU, or RU. In an ORAN system, the CU can also be called an open (O)-CU, the DU can be called an O-DU, the CU-CP can be called an O-CU-CP, and the CU-UP can be called an O-CU-UP, etc. The network device deployment methods listed herein are merely examples. As standard technologies evolve, network devices may have other deployment forms, and this application does not limit them.

[0074] In some deployments, multiple RAN nodes collaborate to assist terminals in achieving wireless access, with different RAN nodes each implementing a portion of the access network's functions. For example, a RAN node can be a CU, DU, CU-CP, CU-UP, or RU, etc. CUs and DUs can be configured separately or included in the same network element, such as a BBU. RUs can be included in radio frequency equipment or radio frequency units, such as RRUs, AAUs, or RRHs.

[0075] RAN nodes can support one or more types of fronthaul interfaces, each corresponding to a DU and RU with different functions. If the fronthaul interface between the DU and RU is a common public radio interface (CPRI), the DU is configured to implement one or more baseband functions, and the RU is configured to implement one or more radio frequency functions. If the fronthaul interface between the DU and RU is another type of interface, relative to CPRI, some downlink and / or uplink baseband functions, such as, for downlink, precoding, digital beamforming (BF), or one or more of inverse fast Fourier transform (IFFT) / cyclic prefix addition (CP), are moved from the DU to the RU; and for uplink, digital beamforming (BF), or one or more of fast Fourier transform (FFT) / cyclic prefix removal (CP), are moved from the DU to the RU. In one possible implementation, the interface can be an enhanced common public radio interface (eCPRI). Under the eCPRI architecture, the segmentation between DU and RU differs, corresponding to different categories (Cat) of eCPRI, such as eCPRI Cat A, B, C, D, E, F.

[0076] Taking eCPRI Cat A as an example, for downlink transmission, the DU is configured to implement one or more functions before and after layer mapping (i.e., coding, rate matching, scrambling, modulation, and layer mapping), while other functions after layer mapping (e.g., resource element (RE) mapping, digital beamforming (BF), or one or more functions of inverse fast Fourier transform (IFFT) / adding cyclic prefix (CP)) are moved to the RU. For uplink transmission, the DU is configured to implement one or more functions before and after demapping (i.e., decoding, rate matching de-matching, descrambling, demodulation, inverse discrete Fourier transform (IDFT), channel equalization, and demapping), while other functions after demapping (e.g., digital BF or one or more functions of fast Fourier transform (FFT) / removing CP) are moved to the RU. It is understandable that the functional descriptions of the DU and RU corresponding to various types of eCPRI can be found in the eCPRI protocol, and will not be elaborated here.

[0077] In one possible design, the processing unit in the BBU used to implement baseband functions is called the baseband high (BBH) unit, and the processing unit in the RRU / AAU / RRH used to implement baseband functions is called the baseband low (BBL) unit.

[0078] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0079] In this application embodiment, the device for implementing the function of the network device can be the network device itself; it can also be a device capable of supporting the network device in implementing the function, such as a chip system. The device can be installed in the network device or used in conjunction with the network device. For ease of description, when specific examples are mentioned below, the technical solution provided in this application embodiment will be described using a base station as an example.

[0080] Network devices and / or terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and satellites. This application does not limit the scenario in which the network devices and terminal devices are located. Furthermore, terminal devices and network devices can be hardware devices, or software functions running on dedicated hardware or general-purpose hardware, such as virtualization functions instantiated on a platform (e.g., a cloud platform), or entities that include dedicated or general-purpose hardware devices and software functions. This application does not limit the specific form of the terminal devices and network devices.

[0081] It should be noted that the network application architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network application architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0082] To facilitate understanding of the solutions provided in the embodiments of this application, the relevant concepts involved in the embodiments of this application are introduced below:

[0083] 1. Multimodal data

[0084] With the continuous advancement of artificial intelligence (AI) technology, multimodality has become a highly anticipated research direction. Multimodal technology aims to integrate different types of data and information to achieve more accurate and efficient AI applications. Multimodality refers to the simultaneous interaction of information using two or more senses. In the field of AI, multimodal technology enhances the AI ​​system's ability to understand and process complex information by integrating data and information from different senses, thereby improving performance and application scope. Multimodal applications refer to applications that utilize multiple interaction methods to communicate and interact with computer systems (such as immersive multimodal virtual reality (VR) applications). These interaction methods can include sound, images, gestures, touch, and voice. The goal of multimodal applications is to achieve a more intelligent, natural, and efficient user experience, enabling users to communicate with computers more intuitively. In the past, computers and humans primarily interacted through keyboards and mice, but now, multimodal applications are gradually emerging, integrating multiple interaction methods such as sound, images, and gestures to bring users a richer and more natural experience.

[0085] Multimodal data acquisition refers to the simultaneous acquisition of multiple types of data and information. In the field of artificial intelligence, this includes diverse data formats such as images, audio, video, and text. Multimodal data is comprehensively acquired by using different sensors or devices, such as cameras, microphones, and radar. This method provides richer and more comprehensive information, helping to improve system performance and accuracy. This multimodal data can be a multimodal data stream. A data stream refers to the flow and processing of data within a computer system; it describes the direction and processing of data from input to output, helping developers understand the system's structure and function, and facilitating system design and optimization. Data streams can transfer data between components, enabling them to work collaboratively and achieve system functionality. In this embodiment, the multimodal data stream can be an audio data stream, a tactile data stream, a video data stream, etc., and is not limited thereto.

[0086] Multimodal data fusion aims to integrate different types of data and information to obtain more accurate and comprehensive information. This data and information involves multiple senses and sensors, such as vision, hearing, and touch. Fusion methods include feature fusion and deep fusion. Through multimodal data fusion, artificial intelligence systems can better understand and process complex information, improving performance and application scope.

[0087] Multimodal learning refers to the simultaneous use of multiple types of data and information in machine learning tasks. In the field of artificial intelligence, multimodal learning involves various aspects such as image classification, speech recognition, and natural language processing. Through multimodal learning, systems can make fuller use of various types of data and information, improving performance and applicability.

[0088] 2. Synchronization of multimodal data

[0089] One research direction for extended reality (XR) in the standard is multimodal synchronization and scheduling enhancement. Specifically, this research direction aims to facilitate efficient and effective support for XR applications with multimodal quality of service (QoS) data streams, ensuring these data streams are interdependent and meet multimodal QoS requirements, such as synchronization and / or coordination (see TR 22.847, TR 23.700 60). Improvements in efficiency in terms of capability and power consumption are expected. Potential issues raised include: (a) signaling from the core network and / or enhanced RAN awareness by the UE; (b) enhancing the user plane, such as scheduling, link control protocol (LCP), resource allocation, and dropdown; and (c) supporting multiple Drx configurations, independent of pre-rel-19 2. nd The potential limitations of DRX.

[0090] For example, to enhance the synchronization between multimodal data streams, enhanced scheduling (LCP) mechanisms have been proposed. For instance, delayed data streams can be given higher priority; or, data can be dropped between data streams to maintain synchronization, discarding data that cannot meet synchronization requirements, thus achieving delay-aware scheduling and reporting delay events; or, the network side can configure an asynchronous drop threshold, and when the asynchronous threshold is met, the relevant data packets can be dropped.

[0091] XR, or Virtual Reality, refers to the use of computers to combine the real and virtual worlds, creating an interactive virtual environment. It's a collective term for various technologies such as Augmented Reality (AR), Virtual Reality (VR), and Mixed Reality (MR). XR services require synchronization between different data streams, a need typically found in multimodal applications. Taking immersive multimodal VR applications as an example, multimodal data streams exist between different media components. During VR viewing, video and audio data streams may coexist. For each frame or segment of video, there is often corresponding audio. This can be understood as each video frame having one or more audio data packets that are content-related to the video and require synchronized transmission. Users need to hear the corresponding sound while watching the video to achieve a satisfactory viewing experience. If the arrival times of the corresponding video and audio data at the user's player differ significantly, it can lead to audio-visual desynchronization, severely degrading the user experience.

[0092] Therefore, the synchronization of multimodal data streams between different media components is crucial to avoid negative impacts on user experience (i.e., viewers detect a lack of synchronization).

[0093] As shown in Table 1, the threshold values ​​for the time difference between different data streams are as follows: For the audio and haptic components, the threshold value for the time difference between the audio data stream and the haptic data stream is 50ms, and the threshold value for the time difference between the haptic data stream and the audio data stream is 25ms. For the video and haptic components, the threshold value for the time difference between the video data stream and the haptic data stream is 15ms, and the threshold value for the time difference between the haptic data stream and the video data stream is 50ms. When the time difference between two data streams exceeds the corresponding threshold value, the synchronization between the two data streams will decrease.

[0094] Table 1

[0095] In one implementation, the network device can configure a threshold for the time difference between the two data streams. When the time difference between the two data streams exceeds the threshold, the terminal device will report to the network device that the two data streams are out of sync.

[0096] As shown in Figure 2, data stream A is a haptic data stream, and data stream B is an audio data stream. Data stream A is ordered by timestamps as PDU2, PDU3, PDU4, PDU5, and PDU6; in data stream A, the timestamp corresponding to PDU2 is 11.11ms, PDU3 is 22.22ms, PDU4 is 33.33ms, PDU5 is 44.44ms, and PDU6 is 55.55ms. Data stream B is ordered by timestamps as PDU4 and PDU5; in data stream B, the timestamp corresponding to PDU4 is 60ms, and PDU5 is 80ms.

[0097] Assuming the network device configures a threshold of 20ms for the time difference between the haptic data stream and the audio data stream for the terminal device, it is necessary to calculate the amount of data when the time difference between data stream A and data stream B exceeds this threshold. Specifically, the time difference between the timestamp corresponding to PDU2 in data stream A and the timestamp corresponding to PDU4 in data stream B is: 60ms - 11.11ms = 48.89ms; the time difference between the timestamp corresponding to PDU3 in data stream A and the timestamp corresponding to PDU4 in data stream B is: 60ms - 22.22ms = 37.78ms; the time difference between the timestamp corresponding to PDU4 in data stream A and the timestamp corresponding to PDU4 in data stream B is: 60ms - 33.33ms = 26.67ms; the time difference between the timestamp corresponding to PDU5 in data stream A and the timestamp corresponding to PDU4 in data stream B is: 60ms - 44.44ms = 15.56ms; and the time difference between the timestamp corresponding to PDU2 in data stream A and the timestamp corresponding to PDU4 in data stream B is: 60ms - 55.55ms = 4.45ms. Therefore, it is evident that the time difference between PDU2, PDU3, and PDU4 in data stream A exceeds the threshold (20ms). Thus, PDU2, PDU3, and PDU4 in data stream A can be considered asynchronous data relative to data stream B. Subsequently, the terminal device can report PDU2, PDU3, and PDU4 in data stream A to the network device, allowing the network device to prioritize these data and achieve synchronization between the data streams.

[0098] However, this method of data stream synchronization still has shortcomings, resulting in high signaling overhead. Therefore, how to improve the synchronization between data streams while reducing signaling overhead during data transmission is an urgent problem to be solved.

[0099] Therefore, in order to improve the synchronization between data streams and reduce signaling overhead, this application provides an information reporting method and a communication device. The information reporting method and communication device provided in the embodiments of this application will be further described in detail below.

[0100] Figure 3 is a flowchart illustrating an information reporting method provided in an embodiment of this application. As shown in Figure 3, the information reporting method includes the following steps S301 to S303. The method execution subject shown in Figure 3 can be the terminal device and network device mentioned above. Alternatively, the method execution subject shown in Figure 3 can be a chip in the terminal device and a chip in the network device; this embodiment of the application does not impose any limitations. Figure 3 illustrates the method using a terminal device and a network device as examples of the method execution subjects.

[0101] S301, the network device sends first information to the terminal device, the first information being used to determine a first threshold and / or a second threshold. Accordingly, the terminal device receives the first information from the network device.

[0102] S302, the terminal device sends first indication information to the network device, the first indication information being determined based on the first threshold and / or the second threshold. Accordingly, the network device receives the first indication information from the terminal device.

[0103] S303. The network device configures the second transmission resources for the terminal device based on the first instruction information.

[0104] In this embodiment, the network device can configure one or more thresholds (such as a first threshold and / or a second threshold) to the terminal device through first information, so that the terminal device can monitor information such as the asynchronous state or the amount of asynchronous data between different data streams. Here, the data stream can be a multimodal data stream, such as an audio data stream, a haptic data stream, a video data stream, etc., and is not limited thereto.

[0105] As an example, the first threshold here could be a time-related threshold used to determine whether different data streams are out of sync. For instance, if the time difference between two data streams is greater than or equal to the first threshold, it indicates that the two data streams are out of sync; if the time difference between two data streams is less than the first threshold, it indicates that the two data streams are synchronized. The second threshold here could be a data volume-related threshold used to determine whether the amount of out-of-sync data between different data streams exceeds the second threshold.

[0106] When a terminal device detects that different data streams are out of sync and / or the amount of out-of-sync data exceeds a second threshold, it will trigger the terminal device to report a first indication to the network device. This indicates the urgency of increasing uplink transmission resources, allowing the network device to allocate transmission resources (i.e., second transmission resources) to the terminal device as quickly as possible based on the first indication. This ensures that out-of-sync data can be prioritized for scheduling or transmission, thereby keeping the time difference between different data streams within the threshold (as shown in Table 1) and improving the synchronization between different data streams. Furthermore, since the terminal device only reports the first indication (e.g., it can occupy 1 bit), indicating only that different data streams are out of sync and / or the amount of out-of-sync data exceeds the threshold, and does not directly report the amount of out-of-sync data, signaling overhead is reduced to some extent, and reporting latency is lowered.

[0107] It should be noted that different data streams can be directional. Taking the first and second data streams as examples, the time difference between the two data streams can be the time difference between the first data stream and the second data stream, or the time difference between the second data stream and the first data stream. The two data streams being out of sync can be either the first data stream being out of sync with the second data stream, or the second data stream being out of sync with the first data stream. The amount of out-of-sync data between the two data streams can be either the amount of asynchronous data between the first and second data streams, or the amount of asynchronous data between the second and first data streams.

[0108] Furthermore, each data stream has a corresponding threshold for the time difference. Synchronization between different data streams can be ensured by guaranteeing that the time difference remains within this threshold. For example, as shown in Table 1 above, the threshold for the time difference between the audio data stream and the haptic data stream is 50ms, and the threshold for the haptic data stream and the audio data stream is 25ms; the threshold for the time difference between the video data stream and the haptic data stream is 15ms, and the threshold for the haptic data stream and the video data stream is 50ms. Therefore, it is necessary to ensure that the first threshold is less than the threshold corresponding to each data stream, thereby reserving some time for the network device to configure transmission resources for the terminal device, while simultaneously ensuring that the time difference between different data streams remains within the threshold, thus improving the synchronization between them.

[0109] For example, taking audio and haptic data streams as examples, the threshold for the time difference between the haptic data stream and the audio data stream is 25ms. The network device can configure a first threshold and a second threshold for the terminal device, where the first threshold can be 20ms (i.e., less than the threshold) and the second threshold is 10kb. If the terminal device detects a time difference of 22ms between the haptic data stream and the audio data stream, exceeding the first threshold, it can be considered that the haptic data stream and the audio data stream are out of sync. The terminal device also detects that the amount of out-of-sync data between the haptic data stream and the audio data stream is 12kb, exceeding the second threshold. The calculation method for the amount of out-of-sync data between the two data streams can refer to the method described in Figure 2 above, and will not be repeated here. Therefore, the terminal device can send a first indication message to the network device, indicating that the haptic data stream is out of sync with the audio data stream, and / or that the amount of out-of-sync data between the haptic data stream and the audio data stream is greater than the second threshold. Once the network device receives the first instruction, it can quickly configure the corresponding transmission resources for the terminal device so that these asynchronous data can be prioritized for scheduling or transmission.

[0110] In one possible implementation, the first information can be used to determine a first threshold and / or a second threshold. The first indication information is described in detail below under different circumstances.

[0111] Scenario 1: This first information is used to determine the first threshold.

[0112] In a specific implementation, taking the first data stream and the second data stream as examples, if the first time difference between the first data stream and the second data stream is greater than or equal to the first threshold, then the first indication information is used to indicate that the first data stream and the second data stream are in an asynchronous state.

[0113] This can be understood as follows: the first threshold is used to determine whether different data streams are out of sync. As shown in Figure 4A, the network device sends first information to the terminal device, which is used to determine the first threshold. When the first time difference between the first data stream and the second data stream is greater than or equal to the first threshold, the terminal device considers the first data stream and the second data stream to be out of sync, and can then report to the network device through the first indication information. The network device will then allocate second transmission resources to the terminal device as soon as possible according to the first indication information to improve the synchronization between the data streams. The calculation method of the first time difference between the first data stream and the second data stream can refer to the method described in Figure 2 above, and will not be repeated here. When the first time difference between the first data stream and the second data stream is less than the first threshold, the first data stream and the second data stream are considered to be in sync, and the terminal device can continue monitoring without reporting.

[0114] Optionally, the first data stream and the second data stream are directional, that is, the first time difference between the first data stream and the second data stream can be the time difference between the first data stream and the second data stream, or the time difference between the second data stream and the first data stream.

[0115] Therefore, the first threshold can be set the same or different for different types of data streams under different circumstances, thereby improving the flexibility of the first threshold. For example, haptic data streams have lower latency requirements and smaller data volumes compared to audio data streams, while audio data streams have lower latency requirements and larger data volumes compared to haptic data streams. Therefore, the first threshold used for haptic data streams relative to audio data streams can be higher than the first threshold used for audio data streams relative to haptic data streams, which helps to save power consumption.

[0116] As an example, the first threshold may include a first value and / or a second value, which may be the same or different. The first value may be a threshold corresponding to the time difference between the first data stream and the second data stream, and the second value may be a threshold corresponding to the time difference between the second data stream and the first data stream. Specifically:

[0117] A. If the time difference between the first data stream and the second data stream is greater than or equal to the first value, then the first indication information is used to indicate that the first data stream is out of sync with the second data stream.

[0118] B. If the time difference between the second data stream and the first data stream is greater than or equal to the second value, then the first indication information is used to indicate that the second data stream is out of sync with the first data stream.

[0119] Scenario 2: This first information is used to determine the first threshold and the second threshold.

[0120] For scenario two, the first instruction message has the following two instruction methods.

[0121] Method 1: The first indication information directly indicates that the amount of asynchronous data between different data streams exceeds the threshold.

[0122] In a specific implementation, taking the first data stream and the second data stream as examples, if the first data volume corresponding to the first time difference being greater than or equal to the first threshold is greater than or equal to the second threshold, then the first indication information is used to indicate that the amount of asynchronous data between the first data stream and the second data stream is greater than or equal to the second threshold. Here, the first time difference is the aforementioned first time difference between the first data stream and the second data stream.

[0123] This can be understood as the second threshold being a threshold related to the amount of data, used to determine whether the amount of asynchronous data between different data streams exceeds this second threshold. The first data volume corresponding to the first time difference between the first data stream and the second data stream being greater than or equal to the first threshold can be considered as the amount of asynchronous data between the first data stream and the second data stream. The calculation method for the amount of asynchronous data between the first data stream and the second data stream can be referred to the method described in Figure 2 above, and will not be elaborated here.

[0124] As shown in Figure 4B, the network device sends first information to the terminal device, which is used to determine a first threshold and a second threshold. When the first time difference between the first data stream and the second data stream is greater than or equal to the first threshold, it is considered that the first data stream and the second data stream are currently out of sync. Further, when the first data volume (i.e., the amount of out-of-sync data) corresponding to the first time difference between the first data stream and the second data stream being greater than or equal to the first threshold is greater than or equal to the second threshold, it can report to the network device through a first indication message; the network device will then allocate second transmission resources to the terminal device as quickly as possible according to the first indication message to improve the synchronization between the data streams. When the first data volume (i.e., the amount of out-of-sync data) corresponding to the first time difference between the first data stream and the second data stream being greater than or equal to the first threshold is less than the second threshold, the terminal device can continue monitoring without reporting.

[0125] In this way, network devices can know that the amount of asynchronous data between different data streams is greater than or equal to a second threshold. Based on the size of the second threshold, the size of the asynchronous data can be estimated, which makes it easier for network devices to configure transmission resources for terminal devices.

[0126] Optionally, the first data stream and the second data stream are directional; that is, the first time difference between the first data stream and the second data stream can be the time difference between the first data stream and the second data stream, or the time difference between the second data stream and the first data stream. Similarly, the amount of asynchronous data between the first data stream and the second data stream can be the amount of asynchronous data between the first data stream and the second data stream, or the amount of asynchronous data between the second data stream and the first data stream.

[0127] Therefore, for data streams of different business types, the first and second thresholds can be set the same or different under different circumstances, thereby improving the flexibility of the first threshold. As an example, the first threshold may include a first value and / or a second value, which can be the same or different; the second threshold may include a third value and / or a fourth value, which can be the same or different. Specifically: The first value can be a threshold corresponding to the time difference between the first and second data streams; the second value can be a threshold corresponding to the time difference between the second and first data streams; the third value can be a threshold corresponding to the amount of asynchronous data between the first and second data streams; and the fourth value can be a threshold corresponding to the amount of asynchronous data between the second and first data streams.

[0128] A. If the amount of data in the first data stream corresponding to the time difference between the first data stream and the second data stream is greater than or equal to the first value, and the amount of data in the first data stream is greater than or equal to the third value, then the first indication information is used to indicate that the amount of asynchronous data in the first data stream relative to the second data stream is greater than or equal to the third value.

[0129] B. If the amount of data in the second data stream corresponding to the time difference between the second data stream and the first data stream is greater than or equal to the second value, and the amount of data in the second data stream is greater than or equal to the fourth value, then the first indication information is used to indicate that the amount of asynchronous data in the second data stream relative to the first data stream is greater than or equal to the fourth value.

[0130] Based on the above, optionally, for method 1, the first indication information is further used to indicate that the first data stream and the second data stream are in a state of asynchrony. Specifically, it can indicate that the first data stream is in a state of asynchrony relative to the second data stream, or that the second data stream is in a state of asynchrony relative to the first data stream.

[0131] Method 2: The first indication information indicates that the ratio of the asynchronous data volume between different data streams to the uplink transmission resource (i.e. the current first transmission resource) exceeds the threshold.

[0132] In a specific implementation, taking the first data stream and the second data stream as examples, if the ratio of the first data volume to the first transmission resource corresponding to the first time difference being greater than or equal to the first threshold is greater than or equal to the second threshold, then the first indication information is used to indicate the ratio. Here, the first time difference is the aforementioned first time difference between the first data stream and the second data stream.

[0133] This can be understood as the second threshold being a ratio-related threshold used to determine whether the ratio of the asynchronous data volume between different data streams to the first transmission resource exceeds the second threshold. The first data volume corresponding to a first time difference between the first data stream and the second data stream that is greater than or equal to the first threshold can be considered as the asynchronous data volume between the first data stream and the second data stream. The first transmission resource is the uplink transmission resource of the current terminal device. The calculation method for the asynchronous data volume between the first data stream and the second data stream can be referred to the method described in Figure 2 above, and will not be elaborated here.

[0134] As shown in Figure 4C, the network device sends first information to the terminal device, which is used to determine a first threshold and a second threshold. When the first time difference between the first data stream and the second data stream is greater than or equal to the first threshold, it is considered that the first data stream and the second data stream are currently out of sync. Further, when the ratio of the first data volume (i.e., the amount of out-of-sync data) corresponding to the first time difference between the first data stream and the second data stream being greater than or equal to the first threshold to the first transmission resource is greater than or equal to the second threshold, the network device can report this ratio to the network device through first indication information; the network device will then allocate second transmission resources to the terminal device as quickly as possible according to the first indication information to improve the synchronization between the data streams. When the ratio of the first data volume (i.e., the amount of out-of-sync data) corresponding to the first time difference between the first data stream and the second data stream being greater than or equal to the first threshold to the first transmission resource is less than the second threshold, the terminal device can continue monitoring without reporting.

[0135] In this way, network devices can know the ratio of the asynchronous data volume between different data streams to the first transmission resource. Based on the size of this ratio and the first transmission resource, the size of the asynchronous data volume can be deduced, thus facilitating the network device to configure transmission resources for the terminal device.

[0136] Optionally, the first data stream and the second data stream are directional; that is, the first time difference between the first data stream and the second data stream can be the time difference between the first data stream and the second data stream, or the time difference between the second data stream and the first data stream. Similarly, the amount of asynchronous data between the first data stream and the second data stream can be the amount of asynchronous data between the first data stream and the second data stream, or the amount of asynchronous data between the second data stream and the first data stream.

[0137] Therefore, for data streams of different service types, the settings of the first threshold and the second threshold can be the same or different under different circumstances. The first threshold may include a first value and / or a second value, which can be the same or different; the second threshold may include a third value and / or a fourth value, which can be the same or different. Specifically: the first value can be a threshold corresponding to the time difference between the first data stream and the second data stream; the second value can be a threshold corresponding to the time difference between the second data stream and the first data stream; the third value can be a threshold corresponding to the ratio of the asynchronous data volume of the first data stream relative to the second data stream to the first transmission resource; and the fourth value can be a threshold corresponding to the ratio of the asynchronous data volume of the second data stream relative to the first data stream to the first transmission resource.

[0138] A. If the ratio of the amount of data in the first data stream to the first transmission resource is greater than or equal to the first value when the time difference between the first data stream and the second data stream is greater than or equal to the first value, then the first indication information is used to indicate that the ratio of the amount of asynchronous data in the first data stream relative to the second data stream to the first transmission resource is greater than or equal to the third value.

[0139] B. If the ratio of the amount of data in the second data stream to the first transmission resource is greater than or equal to the fourth value when the time difference between the second data stream and the first data stream is greater than or equal to the second value, then the first indication information is used to indicate that the ratio of the amount of asynchronous data in the second data stream relative to the first data stream to the first transmission resource is greater than or equal to the fourth value.

[0140] Based on the above, optionally, for method 2, the first indication information is further used to indicate that the first data stream and the second data stream are in a state of asynchrony. Specifically, it can indicate that the first data stream is in a state of asynchrony relative to the second data stream, or that the second data stream is in a state of asynchrony relative to the first data stream. It should be noted that the "ratio" mentioned here can also be called a proportion or multiple, and is not limited here.

[0141] Scenario 3: This first piece of information is used to determine the second threshold.

[0142] For scenario three, the first instruction message has the following two instruction methods.

[0143] Method 1: The first indication information directly indicates that the amount of asynchronous data between different data streams exceeds the threshold.

[0144] In a specific implementation, taking the first data stream and the second data stream as examples, if the first data volume corresponding to the first time difference being greater than or equal to the first threshold is greater than or equal to the second threshold, then the first indication information is used to indicate that the amount of asynchronous data between the first data stream and the second data stream is greater than or equal to the second threshold. Here, the first time difference is the aforementioned first time difference between the first data stream and the second data stream; the first threshold is a predefined value or given by the application and does not need to be issued by the network device.

[0145] As shown in Figure 4D, the network device sends first information to the terminal device, which is used to determine a second threshold. When the first time difference between the first data stream and the second data stream is greater than or equal to the first threshold, and the corresponding first data volume (i.e., the amount of asynchronous data) is greater than or equal to the second threshold, the terminal device can report to the network device via first indication information. The network device will then allocate second transmission resources to the terminal device as quickly as possible based on the first indication information to improve the synchronization between the data streams. When the amount of asynchronous data between the first data stream and the second data stream is less than the second threshold, the terminal device can continue monitoring without reporting. The first threshold is a predefined value.

[0146] Optionally, the first data stream and the second data stream are directional; that is, the first time difference between the first data stream and the second data stream can be the time difference between the first data stream and the second data stream, or the time difference between the second data stream and the first data stream. Similarly, the amount of asynchronous data between the first data stream and the second data stream can be the amount of asynchronous data between the first data stream and the second data stream, or the amount of asynchronous data between the second data stream and the first data stream.

[0147] As an example, the first threshold may include a first value and / or a second value, which may be the same or different; the second threshold may include a third value and / or a fourth value, which may be the same or different. Specifically:

[0148] A. If the amount of data in the first data stream corresponding to the time difference between the first data stream and the second data stream is greater than or equal to the first value, and the amount of data in the first data stream is greater than or equal to the third value, then the first indication information is used to indicate that the amount of asynchronous data in the first data stream relative to the second data stream is greater than or equal to the third value.

[0149] B. If the amount of data in the second data stream corresponding to the time difference between the second data stream and the first data stream is greater than or equal to the second value, and the amount of data in the second data stream is greater than or equal to the fourth value, then the first indication information is used to indicate that the amount of asynchronous data in the second data stream relative to the first data stream is greater than or equal to the fourth value.

[0150] Based on the above, optionally, for method 1, the first indication information is further used to indicate that the first data stream and the second data stream are in a state of asynchrony. Specifically, it can indicate that the first data stream is in a state of asynchrony relative to the second data stream, or that the second data stream is in a state of asynchrony relative to the first data stream.

[0151] It should be noted that the specific implementation of Method 1 in Scenario 3 can be referenced from the specific implementation of Method 1 in Scenario 2 above, and will not be repeated here. The main difference is that the first threshold in Method 1 in Scenario 3 is a predefined value, while the first threshold in Method 1 in Scenario 2 is a value flexibly issued by the network device according to current needs. Therefore, Method 1 in Scenario 2 is more flexible and accurate than Method 1 in Scenario 3.

[0152] Method 2: The first indication information indicates that the ratio of the asynchronous data volume between different data streams to the uplink transmission resource (i.e. the current first transmission resource) exceeds the threshold.

[0153] In a specific implementation, taking the first data stream and the second data stream as examples, if the ratio of the first data volume to the first transmission resource corresponding to the first time difference being greater than or equal to the first threshold is greater than or equal to the second threshold, then the first indication information is used to indicate the ratio. Here, the first time difference is the aforementioned first time difference between the first data stream and the second data stream; the first threshold is a predefined value and does not need to be issued by the network device.

[0154] As shown in Figure 4E, the network device sends first information to the terminal device. This first information is used to determine a first threshold and a second threshold. When the ratio of the first data volume (i.e., the amount of asynchronous data) to the first transmission resource corresponding to the first time difference between the first data stream and the second data stream being greater than or equal to the first threshold is greater than or equal to the second threshold, the network device can report this ratio to the network device through first indication information. The network device will then allocate second transmission resources to the terminal device as quickly as possible according to the first indication information to improve the synchronization between the data streams. When the ratio of the amount of asynchronous data between the first data stream and the second data stream to the first transmission resource is less than the second threshold, the terminal device can continue monitoring without reporting. The first threshold is a predefined value.

[0155] Optionally, the first data stream and the second data stream are directional; that is, the first time difference between the first data stream and the second data stream can be the time difference between the first data stream and the second data stream, or the time difference between the second data stream and the first data stream. Similarly, the amount of asynchronous data between the first data stream and the second data stream can be the amount of asynchronous data between the first data stream and the second data stream, or the amount of asynchronous data between the second data stream and the first data stream.

[0156] As an example, the first threshold may include a first value and / or a second value, which may be the same or different; the second threshold may include a third value and / or a fourth value, which may be the same or different. Specifically:

[0157] A. If the ratio of the amount of data in the first data stream to the first transmission resource is greater than or equal to the first value when the time difference between the first data stream and the second data stream is greater than or equal to the first value, then the first indication information is used to indicate that the ratio of the amount of asynchronous data in the first data stream relative to the second data stream to the first transmission resource is greater than or equal to the third value.

[0158] B. If the ratio of the amount of data in the second data stream to the first transmission resource is greater than or equal to the fourth value when the time difference between the second data stream and the first data stream is greater than or equal to the second value, then the first indication information is used to indicate that the ratio of the amount of asynchronous data in the second data stream relative to the first data stream to the first transmission resource is greater than or equal to the fourth value.

[0159] Based on the above, optionally, for method 2, the first indication information is further used to indicate that the first data stream and the second data stream are in a state of asynchrony. Specifically, it can indicate that the first data stream is in a state of asynchrony relative to the second data stream, or that the second data stream is in a state of asynchrony relative to the first data stream.

[0160] It should be noted that the specific implementation of Method 2 in Scenario 3 can be referenced from the specific implementation of Method 2 in Scenario 2 above, and will not be repeated here. The main difference is that the first threshold in Method 2 of Scenario 3 is a predefined value, while the first threshold in Method 2 of Scenario 2 is a value flexibly issued by the network device according to current needs. Therefore, Method 2 in Scenario 2 is more flexible and accurate than Method 2 in Scenario 3. The "ratio" mentioned here can also be called a proportion or multiple, and is not limited here.

[0161] In addition, for the three scenarios mentioned above, as an example, the first indication information is also used to indicate one or more of the following: the identifier of the service type corresponding to the first data stream, the identifier of the service type corresponding to the second data stream, the identifier of the service type pair, or the identifier of the logical channel group (LCG) corresponding to the first transmission resource. Of course, the first indication information can also be used to indicate other information, which is not limited here.

[0162] The identifiers for various service types are shown in Table 2 below. The identifier for haptic is 0, the identifier for video is 1, and the identifier for audio is 2. For example, if the service type corresponding to the first data stream is haptic, then the first indication information indicates that the identifier for the service type corresponding to the first data stream is 0; if the service type corresponding to the second data stream is video, then the first indication information indicates that the identifier for the service type corresponding to the second data stream is 1.

[0163] Table 2

[0164] This service type pair can indicate the service type corresponding to the first data stream and the service type corresponding to the second data stream. As shown in Table 3 below, the identifiers for the service type pairs are: 0 for haptic-video, 1 for video-haptic, 2 for audio-video, 3 for video-audio, 4 for audio-haptic, and 5 for haptic-audio. For example, if the service type corresponding to the first data stream is haptic and the service type corresponding to the second data stream is video, then the service type pair is haptic-video. Therefore, referring to Table 3, the identifier of the service type pair indicated by this first indication information is 0.

[0165] Table 3

[0166] Of course, the identifier for the service type pair can also be composed of the identifiers of the service type corresponding to the first data stream and the second data stream, or it can be represented in other ways, which are not limited here. As shown in Table 4 below, the identifier corresponding to haptic is 0, the identifier corresponding to video is 1, and the identifier corresponding to audio is 2; the identifiers for service type pairs are: haptic-video is 0-1, video-haptic is 1-0, audio-video is 2-1, video-audio is 1-2, audio-haptic is 2-0, and haptic-audio is 0-2. For example, if the service type corresponding to the first data stream is: haptic, and the service type corresponding to the second data stream is: video, then the service type pair is: haptic-video. Therefore, referring to Table 4, the identifier of the service type pair indicated by the first indication information is 0-1.

[0167] Table 4

[0168] In one possible implementation, the first information can directly indicate the first threshold and / or the second threshold, or it can indirectly indicate the first threshold and / or the second threshold; no limitation is made here. The specific implementation of the first information indicating the first threshold and / or the second threshold is described below.

[0169] Method a: The first information directly indicates the first threshold and / or the second threshold.

[0170] In a specific implementation, the first information may directly include a first threshold and / or a second threshold.

[0171] Method b: The first information indirectly indicates the first threshold and / or the second threshold.

[0172] In a specific implementation, the first information may include a first ratio; the first threshold may be determined based on a first preset value and the first ratio. This can be understood as the first preset value being a pre-set value, and the network device can flexibly configure the first threshold by controlling the ratio of the first preset value. For example, assuming the first preset value is 20ms and the first ratio is 0.8, the first threshold can be determined to be 16ms.

[0173] The first information may include a second ratio; the second threshold may be determined based on a second preset value and the second ratio. This can be understood as the second preset value being a pre-set value, and the network device can flexibly configure the second threshold by controlling the ratio of the second preset value. For example, assuming the second preset value is 10kb and the second ratio is 0.9, the second threshold can be determined to be 9kb.

[0174] It should be noted that the "ratio" mentioned here can also be called a multiple or a level, and is not limited here. Specifically, the ratio can be a range of 0 to 1; or it can indicate 0, 20%, 40%, 80% (specifically, it can be 00, 01, 10, 11), in which case the ratio is 2^the value in the indication * 0.1. Compared to method a, method b allows network devices to configure the first threshold and / or the second threshold more flexibly.

[0175] In one possible implementation, the first indication information is carried in any of the following: uplink control information (UCI), medium access control control element (MAC CE), or scheduling request (SR). Specifically, it can also be reported through buffer status reporting (BSR), which is not limited here.

[0176] For example, when the first indication information is used to indicate that the amount of asynchronous data between the first data stream and the second data stream is greater than or equal to the second threshold, the first indication information can be carried in the UCI; when the first indication information is used to indicate that the ratio of the amount of asynchronous data between the first data stream and the second data stream to the first transmission resource is greater than or equal to the second threshold, the first indication information can be carried in the MAC CE.

[0177] In one possible implementation, the first threshold is related to one or more of the following: the service type corresponding to the first data stream, the service type corresponding to the second data stream, the data volume of the first data stream, or the data volume of the second data stream. This can be understood as the first threshold being set based on the service type and / or data volume corresponding to each data stream. For example, the haptic data stream has a lower latency requirement than the audio data stream, and its data volume is smaller; the audio data stream has a lower latency requirement than the haptic data stream, and its data volume is larger. Therefore, the first threshold used for the haptic data stream relative to the audio data stream can be higher than the first threshold used for the audio data stream relative to the haptic data stream, thereby helping to save power consumption.

[0178] In one possible implementation, the first information is carried in any of the following: downlink control information (DCI), MAC CE, or radio resource control (RRC). Specifically, it can also be reported via buffer status reporting (BSR), which is not limited here. For example, the aforementioned first threshold and / or second threshold, first preset value, second preset value, first ratio, or second ratio can be configured in the RRC.

[0179] In one possible implementation, the method further includes: the terminal device sending the first data volume to the network device. Correspondingly, the network device receives the first data volume from the terminal device. Here, the first data volume refers to the first data volume corresponding to the first time difference between the first data stream and the second data stream being greater than or equal to a first threshold, i.e., the asynchronous data volume between the first data stream and the second data stream. In other words, after the terminal device reports the first indication information to the network device, the terminal device can further send the asynchronous data volume between the first data stream and the second data stream to improve the accuracy and effectiveness of the network device in configuring resources for the terminal device.

[0180] As can be seen, based on the method described in Figure 3, the network device can configure one or more thresholds (such as a first threshold and / or a second threshold) to the terminal device through the first information to monitor information such as the asynchronous state or the amount of asynchronous data between different data streams. For example, the first threshold here can be a time-related threshold used to determine whether different data streams are in an asynchronous state; the second threshold here can be a data volume-related threshold used to determine whether the amount of asynchronous data between different data streams exceeds the second threshold. When the terminal device detects that the current different data streams are in an asynchronous state and / or the amount of asynchronous data between different data streams exceeds the second threshold through these thresholds, it will trigger the terminal device to report the first indication information to the network device to inform the network device of the urgency of increasing uplink transmission resources. This allows the network device to configure transmission resources (i.e., the second transmission resources) for the terminal device as soon as possible according to the first indication information, ensuring that these asynchronous data can be scheduled or transmitted with priority, thereby ensuring that the time difference between different data streams is within the threshold index, and thus improving the synchronization between different data streams. In addition, since the terminal device only reports the first indication information (e.g., it can occupy 1 bit), that is, it only indicates that the current different data streams are in an asynchronous state and / or the amount of asynchronous data exceeds the threshold, and does not directly report the amount of asynchronous data between different data streams, it also reduces the signaling overhead and reduces the reporting latency to a certain extent.
