Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and in particular to a data transmission method and apparatus, and a computer-readable storage medium. Background Technology

[0002] Extended Reality (XR) services involve large amounts of data, typically consisting mainly of downlink video data. This video data transmission is periodic and occurs in bursts. During XR burst transmissions, a large amount of downlink data needs to be transmitted, while a smaller amount of downlink data is transmitted even during burst transmissions. The uplink data for XR services primarily consists of user action indicators and uplink video data, which also exhibits periodicity.

[0003] Typically, wireless communication systems determine their design based on the service data model. Considering the periodic nature of XR video service data, Discontinuous Reception (DRX) technology can be incorporated. By configuring the access network equipment, the terminal device can periodically activate its data receiving module to receive downlink data.

[0004] Reference Figure 1 The diagram illustrates an existing DRX cycle and the timing of downlink video data transmission. However, XR services include other types of data besides video data, which may not be periodic. To receive these other types of data, the terminal device needs to periodically switch from sleep mode to receive mode.

[0048] In existing technologies, for downlink data services, the arrival time of data packets generated by the application server at the access network device typically depends on the transmission latency between the application server and the network, a decision the access network device cannot make. The arrival time of data packets at the terminal device's access layer depends on the application services offered by the terminal device, a decision the 5G transmission module within the terminal device cannot make.

Based on the data transmission capability information of the access network device, the application server can adjust the service data to be transmitted, adjusting the transmission of the service data to be transmitted within one DRX cycle as much as possible, thereby improving the data transmission rate and reducing the power consumption of the terminal device.

[0050] To make the above-mentioned objectives, features and beneficial effects of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

The chip system may include a chip, and may also include other discrete components.

[0052] The access network device in this application embodiment is a device that provides wireless communication functions for terminals, and can also be referred to as a radio access network (RAN) device or access network element. The network device can support at least one wireless communication technology, such as LTE, NR, etc. For example, the network device includes, but is not limited to: next-generation base stations (gNB), evolved node B (eNB), radio network controllers (RNC), node Bs (NBs), base station controllers (BSCs), base transceiver stations (BTSs), home base stations (e.g., home evolved node B, or home node B (HNB)), baseband units (BBUs), transmitting and receiving points (TRPs), transmitting points (TPs), mobile switching centers, etc., in 5th-generation (5G) mobile communication systems.

In some embodiments, network devices can also be means for providing wireless communication functions to UEs, such as chip systems. For example, a chip system may include chips, and may also include other discrete devices.

[0053] This invention provides a data transmission method, referring to... Figure 2 The following will provide a detailed explanation through specific steps.

[0054] In practical implementation, the actions performed by the access network device in the data transmission method provided in steps 201 to 203 below can be performed by a chip with data transmission function in the access network. Similarly, the actions performed by the application server can be performed by a chip with data transmission function in the application server.

[0055] Step 201: The access network device sends data transmission capability information.

[0056] In practical implementation, after determining the Discontinuous Reception (DRX) configuration, the access network device can generate data transmission capability information. This data transmission capability information can be used for service data transmission. Specifically, the data transmission capability information may include first air interface data transmission capability information and / or second air interface data transmission capability information.

[0057] After generating data transmission capability information, the access network device can send the generated data transmission capability information to the Access and Mobility Management Function (AMF) unit.

[0058] In this embodiment of the invention, the first air interface data transmission capability information may include information about a first time period and information about the air interface transmission capacity within the first time period.

[0059] In this embodiment of the invention, the first air interface data transmission capability information can be used to indicate the maximum capacity that the access network device can transmit for the corresponding air interface data of the first user equipment within a first time period.

[0060] For example, in the first air interface data transmission capability information, the first time period is the time period T1 to T2, and the air interface transmission capacity information within the first time period is 100 bytes. At this time, the first air interface data transmission capability information is used to indicate that: within the time period T1 to T2, the access network device can transmit a maximum of 100 bytes of air interface data corresponding to the first user equipment.

[0061] In this embodiment of the invention, the first air interface data transmission capability information may further include first transmission reliability information, which can be used to indicate the success rate of the access network device in transmitting the air interface data corresponding to the first user equipment within a first time period.

[0062] For example, in the first air interface data transmission capability information, the first time period is the period from T1 to T2, the air interface transmission capacity within the first time period is 100 bytes, and the first transmission reliability information is 99.999%. In this case, the first air interface data transmission capability information indicates that within the time period from T1 to T2, the access network device can transmit the air interface data corresponding to the first user equipment with a transmission success rate of 99.999%, and the maximum air interface data corresponding to the first user equipment is 100 bytes.

[0063] In specific implementations, the first air interface data transmission capability information may further include information about the second time period and information about the air interface transmission capacity within the second time period. In this case, the first air interface data transmission capability information can also be used to indicate: the maximum capacity that the access network device can transmit for the air interface data corresponding to the second user equipment within the second time period, and the maximum capacity for transmitting for the air interface data corresponding to the first user equipment.

[0064] Normally, the access network device transmits the air interface data corresponding to the second user equipment during the second time period. In this embodiment of the invention, if the access network device detects that the maximum capacity of the air interface data to be transmitted during the second time period is greater than the maximum capacity of the air interface data required by the second user equipment to be transmitted during the second time period, the access network device may prioritize transmitting the air interface data of the second user equipment during the second time period. After completing the transmission of the air interface data of the second user equipment, the air interface data of the first user equipment is transmitted.

[0065] In other words, during the second time period, the air interface data of the first user equipment has a lower priority than the air interface data of the second user equipment.

[0066] For example, in the first air interface data transmission capability information, the second time period is T3 to T4, and the air interface transmission capacity within the second time period is 100 bytes. Of this, the air interface transmission capacity corresponding to the second user equipment is 60 bytes, and the air interface transmission capacity corresponding to the first user equipment is 40 bytes. In this case, the first air interface data transmission capability information also indicates that within the T3 to T4 time period, the access network device can transmit a maximum of 60 bytes of air interface data corresponding to the second user equipment and a maximum of 40 bytes of air interface data corresponding to the first user equipment, with priority given to transmitting the air interface data of the second user equipment.

[0067] In this embodiment of the invention, the first air interface data transmission capability information may further include second transmission reliability information, which may be used to indicate the success rate of the access network device in transmitting the air interface data corresponding to the first user equipment within a second time period.

[0068] For example, in the first air interface data transmission capability information, the second time period is the T3-T4 time period, the air interface transmission capacity information within the second time period is 100 bytes, and the second transmission reliability information is 99.9%. In this case, the first air interface data transmission capability information indicates that within the T3-T4 time period, the access network device can transmit the air interface data corresponding to the first user equipment with a 99.9% transmission success rate, and the maximum air interface data corresponding to the first user equipment is 40 bytes.

[0069] In this embodiment of the invention, since the second time period is mainly used to transmit the air interface data of the second user equipment, rather than specifically for transmitting the air interface data of the first user equipment, the reliability corresponding to the first transmission reliability information may be lower than the reliability corresponding to the second transmission reliability information.

[0070] In this embodiment of the invention, time T2 and time T3 can overlap. At this time, during time T1 to T2, the access network device transmits the air interface data of the first user equipment, and during time T2 (T2 is actually T3) to T4, the access network device transmits the air interface data of the second user equipment and the air interface data of the first user equipment.

[0071] Time T2 and time T3 may not overlap. In this case, the time period corresponding to time T1 to T2 and the time period corresponding to time T3 to T4 do not overlap.

[0072] In this embodiment of the invention, time T1 can be the start time of the DRX cycle, and the period of time T1 can be the period of the DRX.

[0073] Step 202: AMF sends data transmission capability information to the application server.

[0074] In practice, access network devices can use the AMF (Access Frame Function) to transparently transmit data transmission capability information to the application server (XR server). Access network devices can also forward data transmission capability information through the terminal device (UE).

[0075] In this embodiment of the invention, the access network device can forward data transmission capability information to the terminal device. After receiving the data transmission capability information, the terminal device can forward the data transmission capability information to the application server.

[0076] In other words, access network devices can send data transmission capability information to the application server through AMF, or they can forward data transmission capability information to the application server through terminal devices.

[0077] In practice, access network devices can also notify the application server that data transmission capability information can be applied in one or more DRX cycles.

[0078] In practice, access network devices can send data transmission capability information to one application server or to multiple application servers. When an access network device sends data transmission capability information to multiple application servers, the content carried in the data transmission capability information sent to different application servers can be exactly the same, not exactly the same, or completely different.

[0079] For example, the access network device sends data transmission capability information to application server 1 and application server 2 respectively. The data transmission capability information sent by the access network device to application server 1 includes first air interface data transmission capability information, which indicates that during the time period T1 to T2, the access network device can transmit the air interface data corresponding to the first user equipment with a transmission success rate of 99.999%, and the air interface data corresponding to the first user equipment is at most 100 bytes.

[0080] The data transmission capability information sent by the access network device to the application server 2 includes first air interface data transmission capability information. The first air interface data transmission capability information indicates that: during the time period T1 to T2, the access network device can transmit the air interface data corresponding to the first user equipment with a transmission success rate of 99.99%, and the air interface data corresponding to the first user equipment is at most 100 bytes; during the time period T3 to T4, the access network device can transmit the air interface data corresponding to the first user equipment with a transmission success rate of 99.9%, and the air interface data corresponding to the first user equipment is at most 40 bytes.

[0081] In practical implementation, the transmission success rate and the maximum capacity corresponding to air interface data in the data transmission capability information can refer only to the data success rate and the maximum capacity corresponding to air interface data for uplink data, or only to the data success rate and the maximum capacity corresponding to air interface data for downlink data, or simultaneously include the data success rate and the maximum capacity corresponding to air interface data for each of the uplink and downlink data.

[0082] In practical implementation, data transmission capability information can also be sent to the 5G core network element AF, which is responsible for coordinating downlink data for multiple services. Alternatively, the data transmission capability information can be communicated from the access layer of the terminal device to its application layer, allowing the application layer to adjust the uplink data generation time.

[0083] In practice, the access network device can directly transmit the information for the first time period to the application server. Similarly, the access network device can directly transmit the information for the second time period to the application server. When the access network device transmits time period information (information for the first time period and / or the second time period) to the application server, the access network device and the application server can use the same type of clock.

[0084] In this embodiment of the invention, the access network device can determine T1, T2, T3, and T4 using the time from the Global Positioning System (GPS) clock. The access network device can notify the application server that it is using the GPS clock and the specific time (T1, T2, T3, and T4). Accordingly, the application server uses the GPS clock to determine T1, T2, T3, and T4.

[0085] Understandably, access network devices can also use other types of clocks to determine T1, T2, T3, and T4. The access network device can inform the application server of the type of clock it uses, as well as the specific time (T1, T2, T3, and T4). The application server can then use the same type of clock to determine T1, T2, T3, and T4.

[0086] In practice, access network devices can directly indicate the specific time (T1, T2, T3, and T4) to the application server, or they can indicate the specific time by indicating T1 and the corresponding delay.

[0087] For example, the access network device indicates time T2 using T1+delta1; time T3 using T1+delta2; and time T4 using T1+delta3.

[0088] In practical implementation, access network devices can also forward time period information (information from the first time period and / or the second time period) to the application server via a conversion node. The conversion node can be an AMF, SMF, AF, etc.

[0089] When time period information is forwarded to the application server via the conversion node, the clock type of the access network device and the clock type of the application server can be the same or different.

[0090] If the clock type of the access network device differs from that of the application server, a conversion node can convert the clock type of the access network device to be the same as that of the application server.

[0091] For example, if the access network device uses a subframe number as its clock type and the application server uses an absolute time as its clock type, the conversion node can convert the subframe number sent by the access network device into absolute time and send the absolute time to the application server.

[0092] In this embodiment of the invention, the time period information can be represented by the subframe number, by the absolute time, or by other information that can characterize time.

[0093] Step 203: The application server adjusts the business data to be transmitted based on the data transmission capability information.

[0094] In this embodiment of the invention, step 203 is an optional step. In specific applications, it can be determined whether to use step 203 based on actual needs.

[0095] In practical implementation, after receiving data transmission capability information, the application server can adjust the downlink data of one or more services to ensure that the downlink data of one or more services reaches the access network device within the aforementioned time period (the first time period and / or the second time period). Alternatively, after receiving data transmission capability information, the application layer of the terminal device can adjust the uplink data of one or more services to ensure that the uplink data of one or more services reaches the access layer of the terminal device within the aforementioned time period (the first time period and / or the second time period).

[0096] For example, if the application server learns that the access network device is transmitting data from terminal device A during the first time period (T1~T2), and the downlink data transmission delay from the application server to the access network device is ΔT, then the application server will output the downlink data to the access network device at time T1-ΔT. The downlink data output by the application server to the access network device may include one or more service data corresponding to terminal device A.

[0097] In other words, if the air interface transmission capacity is large in the first time period, the application server can send one or more service data corresponding to terminal device A in the first time period.

[0098] In practice, application servers may find themselves unable to meet the requirements for data transmission capabilities. For example, an application server may find that it cannot adjust downlink data to the first time period.

[0099] For the above application scenarios, the application server can send a feedback notification message to the access network device, informing the access network device that it is unable to adjust the downlink data to the first time period.

[0100] In practice, terminal devices may find that they cannot meet the requirements for data transmission capabilities. For example, a terminal device may find that it cannot adjust uplink data to the first time period.

[0101] For the above application scenarios, the application server can send a feedback notification message to the terminal device, informing the terminal device that it is unable to adjust the uplink data to the first time period.

[0102] In practical implementation, for Extended Reality (XR) services, i.e., XR sessions, the application server divides service data packets with different Quality of Service (QoS) requirements into multiple data flows, which are then transmitted through the access network equipment. A single session can include up to 64 data flows. During transmission, the access network equipment can guarantee the order of data packets within a single data flow, but it cannot guarantee the order of data packets between different data flows.

[0103] In this embodiment of the invention, the second air interface data transmission capability information includes air interface latency information, which can be used to indicate the maximum air interface latency corresponding to the transmission of the first amount of air interface data. By notifying the application layer of the application server or terminal device of the air interface latency information, the application layer of the application server or terminal device can be assisted in determining how many data streams to transmit data.

[0104] In this embodiment of the invention, the application server can adjust the data stream of the service data to be transmitted based on the air interface latency information, wherein the service types corresponding to the service data to be transmitted may not be completely the same.

[0105] The air interface delay information can be used to indicate the maximum air interface delay corresponding to the downlink transmission of the first amount of air interface data, or it can be used to indicate the maximum air interface delay corresponding to the uplink transmission of the first amount of air interface data.

[0106] For example, with a latency budget of 50ms, 100 bytes / s of uplink data can be transmitted. Or, with a latency budget of 50ms, 80 bytes / s of downlink data can be transmitted.

[0107] The following examples will provide a detailed explanation.

[0108] The application server generates two types of business data. The first type of business data includes data packets 1, 2, 3, and 4, and the second type of business data includes data packet A. Data packets 1, 2, 3, and 4 are ordered with data packet A.

[0109] At this point, the application server can send business data in two ways:

[0110] Method 1: Assign data packets 1, 2, 3, and 4 to one data stream, and assign data packet A to another data stream.

[0111] Since the order of data between different data streams cannot be guaranteed, the application server needs to generate additional indication information to notify the receiver that the order of the data packets is 1, 2, 3, A, 4.

[0112] Regarding Method 1, after generating the aforementioned data packet, the application server can immediately forward it to the access network device for transmission. For example, if the application server first generates data packet 4 and then generates data packet A, since data packet 4 and data packet A belong to different data streams, the application server can first send data packet 4 to the access network device for transmission, and then send data packet A to the access network device for transmission. In this case, the access network device has more time to transmit data packet 4.

[0113] Method 2: Pack data packets 1, 2, 3, 4, and A into a single data stream in the order of 1, 2, 3, A, and 4.

[0114] Since data packets 1, 2, 3, 4, and A are in the same data stream, they only need to be sent to the access network device in the order of 1, 2, 3, A, and 4 to ensure their sequential order. In this case, the application server does not need to generate additional instruction information.

[0115] Regarding method two above, if the application server generates data packet 4 first and then data packet A, since data packet 4 lags behind data packet A in the order of a data stream, the application server needs to wait for data packet A to be generated before sending data packet A and data packet 4 to the access network device for transmission in sequence. Therefore, the time allotted for the access network device to transmit data packet 4 may actually be less than the time required to transmit data packet 4 in method one above.

[0116] In this embodiment of the invention, if the application server knows in advance that the latency budget of the access network device is small, the application server can use the second method described above to generate a data stream carrying data packets 1, 2, 3, 4, and A. If the application server knows in advance that the latency budget of the access network device is large, the application server can use the first method described above to generate two data streams, one of which carries data packets 1, 2, 3, and 4, and the other carries data packet A.

[0117] In summary, in this embodiment of the invention, the application server can obtain data transmission capability information, thereby knowing the first air interface data transmission capability and / or the second air interface data transmission capability of the access network device. Based on the data transmission capability information of the access network device, the application server can adjust the service data to be transmitted, ensuring that the service data is sent within one DRX cycle as much as possible, thereby improving the data transmission rate and reducing the power consumption of the terminal device.
