Description

Transmission method and transmission device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on September 27, 2023, with application number 202311270915.X and application name “Transmission Method and Transmission Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the field of communications, and more specifically, to a transmission method and a transmission device. Background Art

[0003] Mobile communication systems often require processing of large bursts of data. For example, cloud-based photo enhancement scenarios involve bursts of data. Typically, after a terminal device takes a photo locally, it performs local image processing to enhance image quality. Common image post-processing techniques include denoising, super-resolution, low-light enhancement, and beautification. Some of these processes require significant computing power, and local processing on the terminal device is limited by its processing capabilities. Once the processing quality reaches a certain level, it's difficult to improve. Cloud-based photo enhancement involves the terminal device uploading photos to the cloud for processing. This requires users to upload photos to the cloud after taking them. After processing in the cloud, the photos are returned to the local device and displayed locally to the user.

[0004] However, for cloud-based photo enhancement scenarios, since the amount of data for each photo is large and the action of taking photos is not periodic but sudden, it brings a series of related problems.

[0097] In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief introduction to the relevant technologies and terms of the present application is first given.

[0098] 1. Principle of cloud photo enhancement.

[0099] Typically, after a terminal device takes a photo locally, it performs local image processing to enhance image quality. Common image post-processing techniques include denoising, super-resolution, low-light enhancement, and beautification. Some of these processes require significant computing power, and local processing on the terminal device is limited by the device's processing capabilities. Once the processing quality reaches a certain level, it's difficult to improve. Cloud-based photo enhancement involves transferring photos to the cloud for processing. The cloud can deploy a large number of graphics processing units (GPUs) for image processing, resulting in superior processing quality compared to local processing. This requires users to upload their photos to the cloud after taking them, and then the cloud processes the photos and returns them to the local computer for display to the user.

[0100] For example, the photos in the cloud-based photo enhancement scenario described above are characterized by sudden big data, with the following specific features:

[0101] The amount of data for each photo is large, and it takes a certain amount of time to submit the data of a photo from the APP layer to the AS layer;

[0102] The action of taking pictures is not periodic, but sudden.

[0103] Optionally, for this type of cloud photography, after the user presses the camera button, before the data is actually generated, the terminal device needs to interact with the network device to determine the maximum data volume and maximum delay that the network device can guarantee. The terminal device then determines the photo format based on the maximum data volume and generates the photo data. For example, taking the cloud-based photo enhancement service as an example, the maximum data volume and maximum delay may be the maximum data volume and maximum delay corresponding to the photo upload service in which the terminal device interacts with the network device. For example, the maximum delay here indicates the time used to transmit data of the service with the maximum data volume. For example, the maximum data volume here may be the maximum value of the data volume corresponding to the data set.

[0104] For example, the maximum data amount may include / be replaced by any one or more of the following: data amount, maximum rate, or rate.

[0105] For example, the maximum delay may include / be replaced by any one or more of the following: delay, maximum time, maximum time, or time.

[0106] 2. Application (APP) layer and access stratum (AS) layer structure.

[0107] In the embodiments of the present application, the communication between the network device and the terminal device follows a certain protocol layer structure.

[0108] A possible protocol layer structure is shown in Figure 1. For the AS layer, the user plane protocol stack may include the service data adaptation protocol (SDAP) layer, the packet data convergence protocol (PDCP) layer, the radio link control (RLC) layer, the medium access control (MAC) layer, and the physical (PHY) layer.

[0109] Another possible protocol layer structure is shown in Figure 2. For the AS layer, the control plane protocol stack may include the radio resource control (RRC) layer, PDCP layer, RLC layer, MAC layer, and PHY layer. In addition, the control plane protocol stack may also include the non-access stratum (NAS).

[0110] In the embodiment of the present application, an APP layer may exist above the AS layer. There may be other layers between the AS layer and the APP layer, which are not limited in the embodiment of the present application.

[0111] 3. Buffer status reporting (BSR)

[0112] 3.1. BSR triggering

[0113] For example, for an existing BSR, a BSR is triggered if one or more of the following occurs for an activated cell group:

[0114] (1) The MAC entity has new uplink (UL) data on a logical channel belonging to a logical channel group (LCG), and one of the following two conditions is met:

[0115] The priority of the logical channel containing the new UL data is higher than the priority of any logical channel containing available UL data in any LCG; or, there is no available UL data in any other logical channel in the LCG.

[0116] (2) UL resources are allocated and the number of padding bits is equal to or greater than the size of the BSR MAC control element (CE) plus its subheader. In this case, the BSR is called a "padding BSR."

[0117] (3) The timer retxBSR-Timer times out and at least one logical channel in the LCG contains UL data. In this case, the BSR is called a "Regular BSR".

[0118] (4) Periodic BSR-Timer times out. In this case, the BSR is called "Periodic BSR".

[0119] 3.2. BSR content.

[0120] For example, the BSR includes the buffer data size (buffer size) of the logical channel in the LCG. The buffer size in the BSR includes the amount of data cached in the PDCP and RLC layers, and does not include the amount of data that has not been sent from the APP layer to the AS layer (or, does not include the amount of data from the APP layer).

[0121] It should be understood that as data is transmitted, the amount of data buffered in the PDCP and RLC layers may vary.

Alternatively, the network device or access device can be a device that implements base station functions in the IoT, such as a device that implements base station functions in drone communications, V2X, D2D, or machine-to-machine (M2M).

[0129] It should be noted that the communication system described in the embodiment of the present application is intended to more clearly illustrate the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided in the embodiment of the present application. Ordinary technicians in this field can know that with the evolution of network architecture and the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

[0130] Optionally, the relevant functions of the terminal device and network device involved in this application can be implemented by one device, or by multiple devices together, or by one or more functional modules within a device, or by one or more chips, or by a system on chip (SOC) or a chip system. The chip system can be composed of chips, or can include chips and other discrete devices. The embodiments of this application do not specifically limit this.

[0131] It is understandable that the above functions can be network elements in hardware devices, software functions running on dedicated hardware, or a combination of hardware and software, or virtualized functions instantiated on a platform (e.g., a cloud platform).

[0132] For example, the functions of the terminal device and network device involved in this application can be implemented by the communication device 400 in Figure 4A. Figure 4A is a schematic diagram of the structure of the communication device 400 provided in an embodiment of the present application. The communication device 400 includes one or more processors 401, a communication line 404, and at least one communication interface (Figure 4A is merely an example of including a communication interface 402 and a processor 401), and optionally may also include a memory 403.

[0133] The processor 401 may be a general-purpose central processing unit (CPU), a microprocessor, an application-specific integrated circuit (ASIC), or one or more integrated circuits for controlling the execution of the program of the present application.

[0134] The communication line 404 may include a path for connecting different components.

[0135] Communication interface 402 may be a transceiver module for communicating with other devices or communication networks, such as Ethernet, RAN, or wireless local area networks (WLAN). For example, the transceiver module may be a device such as a transceiver or a transceiver. Alternatively, communication interface 402 may be a transceiver circuit within processor 401, configured to implement signal input and output to the processor.

[0136] The memory 403 may be a device having a storage function. For example, it may be a read-only memory (ROM) or other types of static storage devices that can store static information and instructions, a random access memory (RAM) or other types of dynamic storage devices that can store information and instructions, or an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compact disc, laser disc, optical disc, digital versatile disc, Blu-ray disc, etc.), a magnetic disk storage medium or other magnetic storage device, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited thereto. The memory may be independent and connected to the processor via a communication line 404. The memory may also be integrated with the processor.

[0137] The memory 403 is used to store computer-executable instructions for executing the solution of the present application, and the execution is controlled by the processor 401. The processor 401 is used to execute the computer-executable instructions stored in the memory 403, thereby implementing the transmission method provided in the embodiment of the present application.

[0138] Alternatively, optionally, in an embodiment of the present application, the processor 401 may also perform processing-related functions in the transmission method provided in the following embodiments of the present application, and the communication interface 402 is responsible for communicating with other devices or communication networks, which is not specifically limited in the embodiments of the present application.

[0139] Optionally, the computer-executable instructions in the embodiments of the present application may also be referred to as application code, which is not specifically limited in the embodiments of the present application.

[0140] In a specific implementation, as an embodiment, the processor 401 may include one or more CPUs, such as CPU0 and CPU1 in FIG. 4A .

[0141] In a specific implementation, as an embodiment, the communication device 400 may include multiple processors, such as the processor 401 and the processor 407 in FIG4A . Each of these processors may be a single-core processor or a multi-core processor. The processors herein may include, but are not limited to, at least one of the following: a central processing unit (CPU), a microprocessor, a digital signal processor (DSP), a microcontroller unit (MCU), or an artificial intelligence processor, and other types of computing devices that run software. Each computing device may include one or more cores for executing software instructions to perform calculations or processing.

[0142] In a specific implementation, as an embodiment, the communication device 400 may further include an output device 405 and an input device 406. The output device 405 communicates with the processor 401 and can display information in a variety of ways. For example, the output device 405 can be a liquid crystal display (LCD), a light emitting diode (LED) display device, a cathode ray tube (CRT) display device, or a projector. The input device 406 communicates with the processor 401 and can receive user input in a variety of ways. For example, the input device 406 can be a mouse, a keyboard, a touch screen device, or a sensor device.

[0143] The communication device 400 described above may also sometimes be referred to as a communication apparatus, and may be a general-purpose device or a dedicated device. For example, the communication device 400 may be a desktop computer, a portable computer, a network server, a personal digital assistant (PDA), a mobile phone, a tablet computer, a wireless terminal device, an embedded device, the aforementioned terminal, the aforementioned network device, or a device having a similar structure to that shown in FIG4A . The embodiments of the present application do not limit the type of the communication device 400.

[0144] In addition, the composition structure shown in Figure 4A does not constitute a limitation on the communication device. In addition to the components shown in Figure 4A, the communication device may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0145] For example, the interaction between the terminal device and the network device can determine the maximum data volume and maximum latency that the network device can guarantee. For example, for a data set (e.g., photo data) or a data set (e.g., data for a single photo), the interaction between the terminal device and the network device can determine the maximum data volume and maximum latency that the network device can guarantee. For example, the terminal device can determine / generate a data set (e.g., a photo, or a photo format) based on the maximum data volume.

[0146] For example, it may take a certain amount of time for a terminal device to generate data (e.g., photo data). If a data set (e.g., a photo data) is the first data set (e.g., the first photo data), according to existing technology, when there is new data, the terminal device will trigger the BSR, so that the network device knows that the data has started and can transmit according to the promised maximum data volume and maximum delay.

[0147] Question 1: For example, as shown in Figure 4B, if a data set (for example, the data of a photo) is not the first data set (for example, the data of the first photo), and the interval between it and the previous data set (for example, the data of the previous photo) is less than the transmission time requirement (or maximum delay) of a data set (for example, the data of a photo) or the previous data set (for example, the data of the previous photo), it is necessary to wait until the previous data set (for example, the data of the previous photo) is completely delivered to the AS layer by the APP before the data of the subsequent photos can be delivered. For the subsequent data set, the subsequent data set will wait for a period of time at the APP layer, which increases the delay of data transmission, and may make it impossible to meet the maximum data volume and maximum delay promised by the network device.

[0148] Optionally, different photos correspond to the same logical channel (LCH).

[0149] Problem 2: For example, a data set (e.g., a photo, or a photo format) determined by a terminal device is within the range guaranteed by the network device, but the network device may not know the specific amount of data. If this data set (e.g., the data for this photo) is followed by other data sets (e.g., data for other photos), for example, if the interval between the two data sets is less than the transmission time requirement (or maximum latency) of a data set (e.g., the data for a photo) or the previous data set (e.g., the data for the previous photo), the data of the two data sets are connected from the APP to the AS layer, and the network device does not know when the previous data set ends. This may cause the network device to be unable to identify the end of the previous data set or the beginning of the next data set. For example, the network device may not know how to determine its scheduling strategy. For example, this may cause the network device to continue scheduling according to its very urgent requirements until the maximum latency corresponding to the previous data set. For example, this may affect network capacity.

[0163] Figure 5 is an example of a transmission method provided by an embodiment of the present application. The method is described by taking the interaction between a terminal device and a network device as an example. Of course, the subject that executes the terminal device action in the method can also be a device / module in the terminal device, such as a chip, processor, processing unit, etc. in the terminal device; the subject that executes the network device action in the method can also be a device / module in the network device, such as a chip, processor, processing unit, etc. in the network device, and the embodiment of the present application does not specifically limit this. For example, as shown in Figure 5, method 500 includes:

[0164] Optionally, S500, the terminal device generates first indication information.

[0165] For example, generating may include / be replaced by: triggering. For example, generating first indication information may include / be replaced by: triggering sending of the first indication information.

[0166] Optionally, when the first condition is met, the terminal device generates first indication information.

[0167] Optionally, when the first condition and the second condition are met, the terminal device generates first indication information.

[0168] S510: The terminal device sends first indication information to the network device. Correspondingly, the network device receives the first indication information from the terminal device.

[0169] For example, the first indication information may be used to indicate that the second data set has been generated. For example, the first indication information may include information that the second data set has been generated. For example, the first indication information may include a specific value of 1 bit, for example, the first indication information is "0", which is used to indicate that the second data set has been generated. The embodiments of the present application do not specifically limit how the first indication information indicates that the second data set has been generated.

[0170] Exemplarily, the first indication information may be sent via a MAC CE, or, alternatively, the first indication information may be sent via a physical uplink control channel (PUCCH) resource, or, the first indication information may be sent via a physical uplink shared channel (PUSCH) resource, or, the first indication information may be sent via an RRC message, or, the first indication information may be sent via a PDCP control protocol data unit (PDU), or, the first indication information may be sent via an RLC control PDU. This embodiment of the present application does not limit this.

[0171] Optionally, when the first condition is met, the terminal device sends a first indication message to the network device.

[0172] In a possible implementation, the first condition is that the second data set has been generated.

[0173] For example, the terminal device sending the first indication information to the network device when the first condition is met may be: the terminal device sending the first indication information to the network device when the second data set has been generated.

[0174] In another possible implementation, the first condition is that the terminal device determines that the second data set has been generated.

[0175] For example, the terminal device sending the first indication information to the network device when the first condition is met may be: the terminal device sending the first indication information to the network device when it is determined that the second data set has been generated.

[0176] Optionally, when the first condition and the second condition are met, the terminal device sends a first indication message to the network device.

[0177] In a possible implementation, the second condition is that the AS layer of the terminal device fails to obtain the second data set.

[0178] For example, the terminal device sends the first indication information to the network device when the first condition and the second condition are met: the terminal device sends the first indication information to the network device when the second data set has been generated and the AS layer of the terminal device has not obtained the second data set, or the terminal device sends the first indication information to the network device when it is determined that the second data set has been generated and the AS layer of the terminal device has not obtained the second data set.

[0179] In another possible implementation, the second condition is that the transmission of the first data set has not been completed.

[0180] For example, the terminal device sends the first indication information to the network device when the first condition and the second condition are met: the terminal device sends the first indication information to the network device when the second data set has been generated and the transmission of the first data set has not been completed, or the terminal device sends the first indication information to the network device when it is determined that the second data set has been generated and the transmission of the first data set has not been completed.

[0181] Optionally, the first data set is transmitted before the second data set.

[0182] Optionally, the first data set is generated before the second data set.

[0183] In the embodiment of the present application, in order to enable readers to more intuitively understand the transmission method provided in the embodiment of the present application, the cloud-based photo enhancement service is taken as an example to illustrate the situation in which the terminal device provided in the embodiment of the present application sends the first indication information to the network device when it is determined that the second data set has been generated and the transmission of the first data set has not been completed. For example, Figure 6 is a schematic diagram of sending the first indication information using the transmission of a picture as an example. As shown in Figure 6, Picture 1 can be the first data set, and Picture 2 can be the second data set. When the transmission of Picture 1 is not completed, Picture 2 is generated at the 2nd second. The terminal device can send the first indication information to the network device at or after the 2nd second.

[0184] Optionally, two exemplary implementations of determining whether the second data set has been generated are provided below:

[0185] In one possible implementation, the AS layer of the terminal device determines that the second data set has been generated based on the first information from the APP layer of the terminal device.

[0186] For example, the first information is used to indicate that the second data set has been generated. For example, the first information includes information that the second data set has been generated.

[0187] Optionally, if the first condition is met, the APP layer of the terminal device sends the first information to the AS layer of the terminal device, or if the first condition and the second condition are met, the APP layer of the terminal device sends the first information to the AS layer of the terminal device. This embodiment of the present application does not limit this.

[0188] Optionally, the AS layer of the terminal device receives the first information from the APP layer of the terminal device, and the AS layer of the terminal device has not yet received the second data set submitted by the APP layer of the terminal device, so that the AS layer of the terminal device can know in advance that the APP layer of the terminal device has generated the second data set without receiving the second data set submitted by the APP layer of the terminal device; or, optionally, the AS layer of the terminal device receives the first information from the APP layer of the terminal device, and the AS layer of the terminal device receives the second data set submitted by the APP layer of the terminal device.

[0232] The transmission method provided in the embodiment of the present application enables the network device to know that the second data set of the terminal device has been generated. Furthermore, the network device can make adjustments such as resource scheduling based on the first indication information, thereby ensuring the delay requirement of data transmission and improving user experience.

[0233] Figure 7 is an example of a transmission method provided by an embodiment of the present application. The method is described by taking the interaction between a terminal device and a network device as an example. Of course, the subject that executes the terminal device action in the method can also be a device / module in the terminal device, such as a chip, processor, processing unit, etc. in the terminal device; the subject that executes the network device action in the method can also be a device / module in the network device, such as a chip, processor, processing unit, etc. in the network device, and the embodiment of the present application does not specifically limit this. For example, as shown in Figure 7, method 700 includes:

[0234] Optionally, in S700, the terminal device generates second indication information.

[0235] For example, generating may include / be replaced by: triggering. For example, generating the second indication information may include / be replaced by: triggering the sending of the second indication information.

[0236] Optionally, when the third condition is met, the terminal device generates second indication information.

[0237] Optionally, when the third condition and the fourth condition are met, the terminal device generates second indication information.

[0238] S710, the terminal device sends second indication information to the network device.

[0239] Correspondingly, the network device receives the second indication information from the terminal device.

[0240] For example, the second indication information may be used to indicate the waiting time, remaining time, or generation time of the second data set. For example, the second indication information may include information about the waiting time, remaining time, or generation time of the second data set.

[0241] For example, the waiting time or the remaining time of the second data set may be determined according to the generation time of the second data set.

[0242] Optionally, when the third condition is met, the terminal device sends a second indication message to the network device.

[0243] In a possible implementation, the third condition is that the AS layer of the terminal device obtains the second data set.

[0244] For example, the terminal device sending the second indication information to the network device when the third condition is met may be: the terminal device sending the second indication information to the network device when the AS layer of the terminal device obtains the second data set.

[0245] Exemplarily, when the second data set is being transmitted, the terminal device sends information indicating the waiting time, remaining time, or generation time of the second data set to the network device. Optionally, the second indication information can be sent once or multiple times during the transmission of the second data set. For example, each time the terminal device sends the second indication information to the network device, the network device can determine the waiting time, remaining time, or generation time of the second data set once. For example, the network device receives the second indication information and can make adjustments such as resource scheduling based on the second indication information. For example, the latency requirements for data transmission can be guaranteed, and the user experience can be improved.

[0246] Optionally, when the third condition and the fourth condition are met, the terminal device sends a second indication message to the network device.

[0247] In a possible implementation, the fourth condition is that when the second data set is generated, the transmission of the first data set has not been completed.

[0248] For example, the terminal device sends the second indication information to the network device when the third and fourth conditions are met: when the terminal device generates the second data set, the transmission of the first data set has not been completed; and, when the AS layer of the terminal device obtains the second data set, the second indication information is sent to the network device.

[0249] Optionally, the first data set is transmitted before the second data set. Optionally, the first data set is generated before the second data set.

[0250] For example, the terminal device sends the second indication information to the network device. Optionally, the second indication information only needs to be sent once.

[0251] For example, after receiving the second indication information, the network device may adjust resource scheduling and the like according to the second indication information to ensure the data transmission delay requirement of the second data set.

[0252] Optionally, the second indication information may be included in a BSR sent by the terminal device to the network device, or, optionally, the second indication information may be included in a delay status report (DSR) sent by the terminal device to the network device, which is not limited in this embodiment of the present application. It should be understood that the terminal device may send one or more BSRs or DSRs to the network device, which is not limited in this embodiment of the present application.

[0254] Optionally, the generation time of the second data set may include / be replaced by: the generation time of part of the data of the second data set; or the generation time of all the data of the second data set, which is not limited in this embodiment of the present application.

[0255] Illustratively, the time when part of the data in the second data set is generated may be the time when the earliest batch or one data in the second data set is generated, which is not limited in this application.

[0256] In a possible implementation, the waiting time may include / be: the waiting time before the second data set reaches the AS layer of the terminal device, or the waiting time of the second data set at the APP layer of the terminal device.

[0257] In a possible implementation, the waiting time may be determined according to the generation time of the second data set and the first time.

[0258] In a possible implementation, the waiting time may be determined according to the generation time of the second data set, which may include / be replaced by: the waiting time may be determined according to the generation time of the second data set and the first time.

[0259] In a possible implementation, the remaining time may be determined according to the generation time of the second data set and the first time.

[0260] In a possible implementation, the remaining time may be determined based on the generation time of the second data set, which may include / be replaced by: the remaining time may be determined based on the generation time of the second data set and the first time.

[0261] Optionally, information about the time the second data set waits before reaching the AS layer of the terminal device, or information about the time the second data set waits at the APP layer of the terminal device, or information about the generation time of the second data set may be included in the second information sent by the APP layer of the terminal device to the AS layer of the terminal device, or in the header of the data of the second data set.

[0262] For example, the second information may be included in a header of the data of the second data set.

[0263] For example, the header may include / be replaced by any one or more of the following: a general packet radio service (GPRS) tunneling protocol for the user plane (GTP-U) header, a NAS layer header, or a header of a layer above the AS layer.

[0264] For example, the second information may optionally include information about the time the second data set waits at the APP layer of the terminal device. Alternatively, the second information may include information about the time the second data set waits before reaching the AS layer of the terminal device. Alternatively, the second information may include information about the remaining time corresponding to the second data set. Alternatively, the second information may include information about the time the second data set was generated.

[0265] For example, the remaining time may be determined according to the generation time of the second data set and the first time. Optionally, if the third condition is met, the APP layer of the terminal device sends the second information to the AS layer of the terminal device.

[0266] Optionally, if the third condition and the fourth condition are met, the APP layer of the terminal device sends the second information to the AS layer of the terminal device.

[0267] In the embodiments of the present application, to provide a more intuitive understanding of the transmission method provided in the embodiments of the present application, the remaining time involved in the embodiments of the present application is described using the cloud-based photo enhancement service as an example. FIG8 is a schematic diagram illustrating the sending of the second indication information when the third and fourth conditions are met in the embodiments of the present application; FIG9 is a schematic diagram illustrating the remaining time corresponding to the transmission of the second data set when the second indication information is sent when the third condition is met in the embodiments of the present application. FIG9 illustrates only a scenario in which the second indication information is sent once; it should be understood that the second indication information can be sent multiple times. As shown in FIG8 , Image 1 can be the first data set, and Image 2 can be the second data set. As shown in FIG9 , Image 2 can be the second data set. In the examples of FIG8 and FIG9 , Image 2 is generated at the 2nd second, and the duration from the generation of the second data set to its completion is 2 seconds. It should be understood that the duration from the generation of the second data set to its completion can be the maximum data transmission delay between the terminal device and the network device described in the related art, i.e., the maximum delay, which will not be further described here.

[0268] Optionally, the first time may be: the time when the terminal device sends the second indication information. For example, the generation time of the second data set is the 2nd second, the time when the terminal device sends the second indication information is the 3rd second, and the remaining time may be the maximum delay (for example, 2 seconds) - (the difference between the generation time of the second data set and the time when the terminal device sends the second indication information (for example, 1 second)) = 1 second.

[0269] Optionally, the first time may be: the time when the terminal device generates the second indication information (not shown in Figures 8 and 9). For example, the generation time of the second data set is the 2nd second, and the time when the terminal device generates the second indication information is the 2.5th second (Figures 8 and 9 show that the sending time of the second indication information is the 3rd second, and the generation time of the second indication information is 0.5 seconds earlier than the sending time of the second indication information), and the remaining time may be the maximum delay (for example, 2s) - (the difference between the generation time of the second data set and the time when the terminal device generates the second indication information (for example, 0.5s)) = 1.5s.

[0270] Optionally, the first time may be: the time when the terminal device determines the second indication information (not shown in Figures 8 and 9). For example, the generation time of the second data set is the 2nd second, and the time when the terminal device determines the second indication information is the 2.4th second (Figures 8 and 9 show that the sending time of the second indication information is the 3rd second, and the determination time of the second indication information is 0.6 seconds earlier than the sending time of the second indication information), and the remaining time may be the maximum delay (for example, 2s) - (the difference between the generation time of the second data set and the time when the terminal device determines the second indication information (for example, 0.4s)) = 1.6s.

[0271] Optionally, the first time may be a time interval of the first duration between the time when the terminal device sends the second indication information. For example, the first time is after or before the time when the terminal device sends the second indication information. For example, the second data set is generated at the 2nd second, the terminal device sends the second indication information at the 3rd second, the first duration is 0.5 seconds (i.e., 0.5 seconds has passed since the terminal device sent the second indication information), and the remaining time may be 0.5 seconds.

[0272] Optionally, the first time may be the time of the second duration of the time interval between the terminal device and the time when the second indication information is generated. For example, the first time is after or before the time when the terminal device generates the second indication information. For example, the second data set is generated at the 2nd second, the terminal device generates the second indication information at the 2.5th second, the second duration is 0.4 seconds (i.e., 0.4 seconds has passed since the terminal generated the second indication information), and the remaining time may be 1.1 seconds.

[0273] Optionally, the first time may be a third time interval between the time when the terminal device determines the second indication information. For example, the first time is after or before the time when the terminal device determines the second indication information. For example, the second data set is generated at 2 seconds, the terminal device determines the second indication information at 2.4 seconds, the third time interval is 0.6 seconds (i.e., 0.6 seconds has passed since the terminal device determined the second indication information), and the remaining time may be 1 second.

[0274] The above are only a few examples of the remaining time. Other schemes that can determine the remaining time should be included in the protection scope of the embodiments of the present application, and the embodiments of the present application do not limit this.

[0275] Optionally, in an embodiment of the present application, the transmission of the first data set that has not yet been completed may include / be replaced by: data of the first data set existing in one or more of the first LCH, the first PDCP entity, the first RLC entity, the first DRB, the AS layer of the terminal device, and the APP layer of the terminal device. This application does not limit this.

[0276] Optionally, in an embodiment of the present application, the first data set is associated with one or more of a first LCH, a first PDCP entity, a first RLC entity, a first DRB, and a first QoS flow.

[0277] Optionally, in an embodiment of the present application, the second data set is associated with one or more of the first LCH, the first PDCP entity, the first RLC entity, the first DRB, and the first QoS flow.

[0279] Optionally, in a possible implementation, the second indication information may further include information about the data volume of the second data set.

[0280] Optionally, the data volume of the second data set includes the data volume of the data in the second data set existing at the APP layer of the terminal device. For example, the data volume of the second data set includes the data volume of the data in the second data set existing at the APP layer of the terminal device and the data volume of the data in the second data set existing at the AS layer of the terminal device.

[0281] Optionally, S720, the network device determines the waiting time, remaining time, or generation time of the second data set according to the second indication information.

[0282] Optionally, in S730, the network device determines a scheduling strategy according to the second indication information.

[0283] In one possible implementation, the network device receives the second indication information and may adjust the scheduling strategy or the data transmission rate, which is not limited in this application.

[0284] In the transmission method provided in an embodiment of the present application, a terminal device sends second indication information indicating the waiting time or remaining time of a second data set to a network device, thereby enabling the network device to learn the waiting time, remaining time, or generation time of the second data set. Furthermore, the network device can adjust resource scheduling and other functions based on the second indication information, for example, transmitting the data of the second data set at a faster rate to ensure the latency requirement for data transmission of the second data set. Alternatively, for example, the network device can determine the end of the second data set.

[0285] Furthermore, optionally, the transmission method provided in the embodiment of the present application may further include: the terminal device sending first indication information to the network device, where the first indication information may be used to indicate that the second data set has been generated.

The first data set is transmitted before the second data set, and the data volume of the third data set includes the data volume of the data in the third data set existing in the APP layer of the terminal device. The description of the third indication information will be described in detail in the following method 1000 and will not be repeated here.

[0287] Furthermore, optionally, the transmission method provided in an embodiment of the present application further includes: the terminal device sending fourth indication information to the network device, where the fourth indication information can be used to indicate that the data in the first data set has been transmitted, wherein the first data set is transmitted before the second data set.

Optionally, upon completion of the transmission of the first data set, the terminal device sends the fourth indication information to the network device.

For example, as shown in Figure 10, method 1000 includes:

[0316] Optionally, S1000, the terminal device generates third indication information.

[0317] For example, generating may include / be replaced by: triggering. For example, generating the third indication information may include / be replaced by: triggering sending of the third indication information.

[0319] S1010, the terminal device sends third indication information to the network device.

[0320] Correspondingly, the network device receives the third indication information from the terminal device.

[0321] For example, the third indication information may be used to indicate the data volume of the third data set. For example, the third indication information may include information about the data volume of the third data set.

[0322] Optionally, the data volume of the third data set may include: the data volume of data in the third data set existing in the APP layer of the terminal device.

[0323] Optionally, the APP layer of the terminal device may send third information to the AS layer of the terminal device.

[0325] For example, the header may include / be replaced by any one or more of the following: a GTP-U header, a NAS layer header, or a header of a layer above the AS layer.

[0326] For example, the third information may indicate the data volume of the data in the third data set existing in the APP layer of the terminal device, or the data volume of the third data set.

[0327] Optionally, the third data set has been generated, or, if the third data set has been generated, or, the terminal device determines that the third data set has been generated, or, if the terminal device determines that the third data set has been generated, the APP layer of the terminal device can send third information to the AS layer of the terminal device.

[0329] Optionally, the data volume of the third data set may be determined based on the data volume of the data in the third data set existing at the APP layer of the terminal device. For example, the data volume of the third data set may be determined based on the data volume of the data in the third data set existing at the APP layer of the terminal device and the data volume of the data in the third data set existing at the AS layer of the terminal device.

[0333] For example, the packet header may include any one or more of the following: a MAC subheader, an RLC header, a PDCP header, or an APP layer header.
