[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on October 31, 2023, with application number 202311447882.1 and invention name “Data Transmission Method, Device and Storage Medium”.

[0003] The present disclosure relates to the field of wireless communication technologies, and in particular to a data transmission method, device, and storage medium. Background Art

[0004] In current wireless communication systems, uplink data transmission is scheduled by the network based on Scheduling Requests (SRs) or Buffer Status Reports (BSRs) from user equipment (UE). Downlink data transmission is scheduled based on the current downlink data volume. The network does not need to consider the complete transmission of large data (such as large files) because large files are already fragmented at the application layer.

[0005] Therefore, the current wireless communication system does not have a transmission control strategy for the large amount of data generated within the system (for example, AI data, perception data, computing power data and other new types of data), and cannot guarantee the reliability of data transmission.

[0030] The following will clearly and completely describe the technical solutions of this disclosure in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of this disclosure without making any creative efforts shall fall within the scope of protection of this disclosure.

[0031] It should be noted that in this disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this disclosure as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0032] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0033] In the description of this disclosure, unless otherwise specified, " / " means "or." For example, A / B can mean A or B. "And / or" in this document simply describes an association relationship between related objects, indicating that three relationships can exist. For example, "A and / or B" can mean: A exists alone, A and B exists simultaneously, and B exists alone. Furthermore, "at least one" means one or more, and "a plurality" means two or more.

[0034] In existing wireless communication systems (for example, Long Term Evolution (LTE), New Radio (NR), etc.), most of the transmitted data comes from the application layer, such as Internet Protocol (IP) packets. The length of IP packets is usually 1500 bytes (standard Ethernet frame) or 9000 bytes (Jumbo frame). In future wireless communication systems (for example, 6th generation mobile communication systems (6G), due to the support of new services such as artificial intelligence (AI), perception and computing power, the data transmitted in the system may not be IP-based packets, but AI data, perception data, computing power data, etc. These data can be collectively referred to as new data. These new data may not come from the application layer, but data generated within the communication system.

[0035] The main difference between this new type of data transmission and IP packets is that for IP packets, the network only needs to ensure the transmission authorization of the IP data packet; for new data, the data itself may be relatively large, and it may take a long time to transmit all the data. During this period, due to equipment or network problems, it may not be guaranteed that the data can be successfully transmitted to the other end within the specified time. Or the receiving end may no longer need the data during the transmission process, or the sending end may no longer be able to transmit the data, etc., resulting in poor reliability of the new type of data transmission.

[0036] As mentioned in the background technology, in the current wireless communication system, for uplink data transmission, the network schedules it through the SR or BSR of the UE; for downlink data transmission, the network schedules it according to the current downlink data volume. The network does not need to consider the complete transmission of large data (such as large files) because large files have been fragmented at the application layer. Therefore, the current wireless communication system does not have a transmission control strategy for data with a large amount of data generated within the system (for example, AI data, perception data, computing power data and other new types of data), and cannot guarantee the reliability of data transmission.

[0037] To address the above technical issues, embodiments of the present disclosure provide a data transmission method, the concept of which is as follows: a first communication node sends a first message to a second communication node requesting the transmission of new data; and then receives a second message sent by the second communication node; the second message is used to indicate whether to transmit the new data between the first communication node and the second communication node. It can be understood that the present disclosure provides a universal data transmission process that can only transmit the new data after both the sender and the receiver confirm that the new data can be transmitted, thereby ensuring the reliability of the data transmission.

[0038] The technical solutions provided in the embodiments of the present disclosure can be applied to various wireless communication systems, for example, NR wireless communication systems, LTE wireless communication systems, future wireless communication systems, or multiple communication convergence systems, etc., and the embodiments of the present disclosure are not limited to this.

[0039] The network architecture of the wireless communication system (including but not limited to 3G, 4G, 5G and future wireless communication systems) in the embodiment of the present disclosure may include at least a first communication node and a second communication node, wherein the first communication node and the second communication node communicate through a wireless channel or a wired channel.

[0040] Exemplarily, the above-mentioned communication nodes (including: the first communication node and the second communication node) can be: a terminal, a base station, a core network element or other network elements that process data.

[0041] It should be understood that in this example, in the downlink, the first communication node can be a network-side device (for example, including but not limited to a base station), and the second communication node can be a terminal-side device (for example, including but not limited to a terminal device). Of course, in the uplink, the first communication node can also be a terminal-side device, and the second communication node can also be a network-side device. In device-to-device communication between the two communication nodes, the first communication node and the second communication node can both be a base station or a terminal device.

[0042] For example, taking the first communication node as a terminal device and the second communication node as a base station, Figure 1 shows a schematic diagram of the architecture of a wireless communication system provided by an embodiment of the present disclosure. As shown in Figure 1, the wireless communication system includes a terminal device 110 and a base station 120. Data is transmitted between the terminal device 110 and the base station 120 via a wireless channel.

[0043] Exemplarily, the terminal device 110 can be a device with wireless transceiver capabilities, which can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it can also be deployed on the water (such as a ship, etc.); it can also be deployed in the air (for example, on an airplane, a balloon, and a satellite, etc.). The terminal device can be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical care, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. The embodiments of the present disclosure do not limit the application scenarios. The terminal device may sometimes also be referred to as a user, UE, access terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal, wireless communication device, UE agent or UE device, etc., which is not limited in the embodiments of the present disclosure.

[0044] Exemplarily, the base station 120 can be a base station or an evolved base station (eNB or eNodeB) in long term evolution (LTE), long term evolution advanced (LTEA), a base station device in a 5G network, or a base station in a future communication system, etc. The base station can include various macro base stations, micro base stations, home base stations, wireless remote stations, reconfigurable intelligent surfaces (RIS), routers, wireless fidelity (WIFI) devices, and other network side devices.

[0045] It should be noted that Figure 1 is only an exemplary framework diagram. The number of devices included in Figure 1 and the names of each device are not restricted. In addition to the devices shown in Figure 1, the wireless communication system may also include other devices, such as core network devices.

[0046] It is understandable that the application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art will appreciate that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are equally applicable to similar technical problems.

[0047] The data transmission method provided by the embodiment of the present disclosure is described in detail below.

[0048] The present disclosure provides a data transmission method, as shown in FIG2 , which includes the following steps S201 - S202 .

[0049] S201: A first communication node sends a first message to a second communication node. Correspondingly, the second communication node receives the first message sent by the first communication node.

[0050] The first message is used to request transmission of new type data between the first communication node and the second communication node.

[0051] In some embodiments, the first communication node may be a data transmitter or a data receiver; the second communication node may be a data receiver or a data transmitter, which is not limited in the present disclosure.

[0052] In some embodiments, the new data is data generated within the communication system. Exemplarily, the new data includes at least one of the following: AI data, perception data, and computing power data.

[0053] In some embodiments, the amount of the new data is greater than the first preset threshold. It is understandable that the amount of the new data is large, reaching hundreds of megabytes, so compared to traditional IP packets, the new data takes longer to transmit and may face more problems.

[0054] In some embodiments, the first message includes at least one of the following: the type of new data to be transmitted, the amount of the new data to be transmitted, and the expected time to complete the transmission. Exemplarily, the type of new data to be transmitted may include at least one of the following: AI data, perception data, and computing power data.

[0055] In some embodiments, the first message can be any one of the following transmission forms: Radio Resource Control (RRC) signaling, Media Access Control (MAC) control element (CE), uplink control information (UCI), downlink control information (DCI), and protocol data unit (PDU).

[0056] In some embodiments, when a first communication node sends a first message to a second communication node, the method further includes: starting a timer T1 to limit a retransmission time. For example, if timer T1 expires and the first communication node has not received a reply message from the second communication node, the first communication node retransmits the first message to the second communication node. If the first communication node receives a reply message from the second communication node before timer T1 expires, the first communication node stops timer T1.

[0057] In some embodiments, the above step S201 may be implemented as: sending a first message to the second communication node when a preset condition is met.

[0058] Exemplarily, the above-mentioned preset conditions include at least one of the following:

[0059] The amount of new data to be transmitted is less than the data amount threshold;

[0060] The signal quality of the signal received by the first communication node is greater than the signal quality threshold;

[0061] The transmission rate of the channel between the first communication node and the second communication node is greater than the transmission rate threshold.

[0062] For example, the data volume threshold can be determined based on the expected transmission completion time; alternatively, the data volume threshold can be determined based on the bandwidth used for data transmission. It is understood that only when the volume of the new data is less than the data volume threshold can the transmission of the new data to be transmitted be ensured within the expected transmission time. Furthermore, when the bandwidth is low, the volume of the new data to be transmitted must also meet the data volume limit corresponding to the bandwidth.

[0063] Exemplarily, the signal quality can be characterized by Reference Signal Received Power (RSRP). The signal received by the first communication node can be a reference signal. It is understood that when the signal quality is greater than a signal quality threshold, it indicates that the channel between the first communication node and the second communication node is in good condition and can be used to transmit new data.

[0064] It can be understood that when the transmission rate of the channel between the first communication node and the second communication node is greater than the transmission rate threshold, it means that the transmission rate of the channel is fast, which can ensure that the new type of data to be transmitted can be transmitted within the expected transmission time.

[0065] In some embodiments, before step S201, the method further includes: configuring configuration parameters related to data transmission. The configuration parameters can be configured by the first communication node or the second communication node. Exemplarily, this can be implemented in the following ways.

[0066] As a possible implementation, as shown in FIG3 , the following steps may be further included before step S201:

[0067] S200a. The first communication node sends configuration parameters related to data transmission to the second communication node. Correspondingly, the second communication node receives the configuration parameters related to data transmission sent by the first communication node.

[0068] The configuration parameters include at least one of the following: data volume threshold, signal quality threshold, and transmission rate threshold. For example, configuring the configuration parameters related to data transmission can be implemented as follows:

[0069] 1. Configure the data volume threshold.

[0070] Configuring the data volume threshold refers to configuring the data volume allowed for new data transmission in the current wireless network. That is, transmission is allowed only when the data volume of the new data to be transmitted is less than or equal to the data volume threshold.

[0071] Exemplarily, when the first communication node and the second communication node are a UE and a base station, respectively, the data volume threshold is used for data transmission between the UE and the base station. The data transmission between the UE and the base station includes uplink transmission and downlink transmission. For example, for uplink transmission, the UE will initiate a data transmission request (e.g., the first message described above) only when the amount of new data to be transmitted is less than or equal to the data volume threshold; for downlink transmission, the base station will schedule the new data to be transmitted only when the amount of new data to be transmitted is less than or equal to the data volume threshold.

[0072] In some embodiments, the data volume threshold may be a threshold at different levels to achieve flexible control and optimization of the wireless communication system. Exemplarily, the data volume threshold may include at least one of the following: UE-level, frequency range (FR)-level, cell group-level, carrier-level, bandwidth part (BWP)-level, or bearer-level parameter.

[0073] The UE-level threshold is set based on the signal quality or other performance indicators of each UE. For example, the threshold can be set based on the RSRP of the UE to ensure that only UEs with signal quality reaching a certain value can transmit new data.

[0074] FR level thresholds are set based on specific frequency ranges. In wireless communication systems, different frequency bands are typically used for different services or communication technologies. By setting FR level thresholds, you can control which frequency bands are used to transmit new types of data.

[0075] Cell group-level thresholds are set based on a group of adjacent base stations. In a cellular network, each cell group consists of multiple base stations. Cell group-level thresholds can be used to control the signal coverage and interference coordination of these base stations.

[0076] Carrier-level thresholds are set based on specific carriers. A carrier is a key concept in wireless communications, representing the specific frequency range of a transmitted signal. Therefore, carrier-level thresholds can be set based on specific carriers. For example, thresholds can be set based on a carrier's signal strength or signal-to-noise ratio (SNR), ensuring that only carriers that meet specific conditions are used.

[0077] The BWP threshold is set based on a specific BWP. BWP is a parameter used to describe frequency band usage in wireless communication systems. Therefore, the BWP threshold can be used to control bandwidth allocation for different services or users within a frequency band.

[0078] Bearer-level thresholds are set based on specific bearers. Bearers are parameters used to describe service load in wireless communications. Bearer-level thresholds can be used to prioritize different services and control traffic flow.

[0079] For example, when the data volume threshold is at the BWP level, a higher data volume threshold may be configured for a BWP with a large bandwidth.

[0080] 2. Configure the signal quality threshold.

[0081] Configuring the signal quality threshold refers to configuring the signal quality level that the current network allows for new data transmission. For example, the signal quality level can be RSRP.

[0082] Exemplarily, when the first communication node and the second communication node are a UE and a base station, respectively, the signal quality threshold is used for data transmission between the UE and the base station. This includes both uplink and downlink transmissions. For example, for uplink transmissions, the UE will initiate a data transmission request (e.g., the first message described above) only when the UE's current RSRP is higher than the signal quality threshold. For downlink transmissions, the base station will schedule new data for transmission only when it determines that the UE's current RSRP is higher than the signal quality threshold.

[0083] In some embodiments, the signal quality threshold may be a threshold at different levels to achieve flexible control and optimization of the wireless communication system. Exemplarily, the signal quality threshold may include at least one of the following: UE-level, FR-level, cell group-level, carrier-level, BWP-level, or bearer-level parameter.

[0084] Exemplarily, if the signal quality threshold is configured as a carrier level, a lower signal quality threshold may be configured for a carrier with a larger coverage area.

[0085] 3. Configure the transmission rate threshold.

[0086] Configuring the transmission rate threshold refers to configuring the rate at which the current network allows new data to be transmitted. That is, new data is allowed to be transmitted only when the transmission rate of the channel between the first communication node and the second communication node is greater than the data volume threshold.

[0087] Exemplarily, when the first communication node and the second communication node are UE and base station respectively, the transmission rate threshold is used for data transmission between the UE and the base station. The transmission between the UE and the base station includes uplink transmission and downlink transmission. For example, for uplink transmission, when the UE determines that the current uplink transmission rate is greater than the transmission rate threshold, the UE will initiate a data transmission request (for example, the above-mentioned first message); or, after the UE initiates an uplink data transmission request, the base station will schedule the uplink data (i.e., the new type of data for uplink transmission) when it determines that the current uplink transmission rate is greater than the transmission rate threshold; for downlink transmission, when the base station determines that the current downlink transmission rate of the UE is greater than the transmission rate threshold, the base station will schedule the downlink data (i.e., the new type of data for downlink transmission).

[0088] In some embodiments, the transmission rate threshold may be a threshold at different levels to achieve flexible control and optimization of the wireless communication system. Exemplarily, the transmission rate threshold may include at least one of the following: UE-level, FR-level, cell group-level, carrier-level, BWP-level, or bearer-level parameter.

[0089] Illustratively, if the transmission rate threshold is configured at the bearer level, a higher transmission rate threshold may be configured for a guaranteed bit rate (GBR) bearer.

[0090] In some embodiments, multiple transmission rate thresholds may be configured, and different transmission rate thresholds may correspond to different data sizes.

[0091] It is understandable that the configuration parameters related to data transmission can be configured by the first communication node and sent to the second communication node.

[0092] As another possible implementation, as shown in FIG4 , before the above step S201, the following steps may be further included:

[0093] S200b: The second communication node sends configuration parameters related to data transmission to the first communication node. Correspondingly, the first communication node receives the configuration parameters related to data transmission sent by the second communication node.

[0094] Exemplarily, the configuration process of the second communication node for the configuration parameters related to data transmission can refer to the above step S200a, which will not be repeated here.

[0095] It is understandable that the configuration parameters related to data transmission can be configured by the second communication node and sent to the first communication node.

[0096] S202: In response to the first message, the second communication node sends a second message to the first communication node. Correspondingly, the first communication node receives the second message sent by the second communication node.

[0097] The second message is used to indicate whether to transmit new type of data between the first communication node and the second communication node.

[0098] In some embodiments, the second message includes one of the following:

[0099] Indication of consent to the transfer of new types of data;

[0100] Instructions to refuse the transmission of new types of data;

[0101] An indication to suspend transmission of new types of data.

[0102] In some embodiments, the above step S202 may be implemented as follows: the second communication node sends a second message to the first communication node according to whether a preset condition is satisfied.

[0103] The description of the preset conditions can be found in step S201 and will not be repeated here.

[0104] Exemplarily, if the second communication node determines that the preset condition is met, the second message sent by the second communication node to the first communication node includes: an indication of consent to transmit the new type of data, or an indication of suspending transmission of the new type of data. If the second communication node determines that the preset condition is not met, the second message sent by the second communication node to the first communication node includes: an indication of refusal to transmit the new type of data, or an indication of suspending transmission of the new type of data.

[0105] In some embodiments, the second message may be in any of the following transmission forms: RRC signaling, MAC CE, DCI, UCI, PDU. It is understood that the transmission form of the second message does not depend on the transmission form of the first message.

[0106] It is understood that, based on the data transmission method provided in the embodiments of the present disclosure, a first communication node can send a first message to a second communication node requesting the transmission of new data; and then receive a second message sent by the second communication node; the second message is used to indicate whether to transmit the new data between the first communication node and the second communication node. In this way, the new data can be transmitted only after both the sender and the receiver confirm that the new data can be transmitted, thereby ensuring the reliability of data transmission.

[0107] In some embodiments, when the second message includes an indication of agreeing to transmit the new type of data, the first communication node and the second communication node enter into a transmission process of the new type of data.

[0108] The flow direction of the new type of data includes: from the first communication node to the second communication node; or from the second communication node to the first communication node.

[0109] In some embodiments, when the new data is transmitted, a timer T2 is started to limit the transmission time of the new data. For example, if the new data has not been transmitted after the timer T2 times out, it means that the actual transmission time of the new data exceeds the expected transmission time.

[0110] In some embodiments, after the new type of data transmission is completed, the peer end is notified that the data transmission is completed, and the timer T2 is stopped.

[0111] In some embodiments, when starting to transmit a new type of data, an indication of starting to transmit data is included in the first packet of data transmitted.

[0112] In some embodiments, during the transmission of new data between the first communication node and the second communication node, both the first communication node and the second communication node may decide to suspend the transmission of the new data and notify the other end.

[0113] As a possible implementation, as shown in FIG5 , after step S202 , the method further includes the following steps:

[0114] S301a: During the transmission of new data, if it is decided to suspend the transmission of the new data, the first communication node sends a third message to the second communication node. Correspondingly, the second communication node receives the third message sent by the first communication node.

[0115] The third message is used to instruct to suspend the transmission of new data between the first communication node and the second communication node.

[0116] S302a. In response to the third message, the second communication node suspends transmission of new data.

[0117] It is understandable that, during the process of transmitting the new type of data, the decision to suspend the transmission of the new type of data may be made by the first communication node, and the decision may be notified to the second communication node.

[0118] As another possible implementation, as shown in FIG6 , after step S202 , the method further includes the following steps:

[0119] S301b: During the transmission of the new type of data, if it is decided to suspend the transmission of the new type of data, the second communication node sends a fourth message to the first communication node. Correspondingly, the first communication node receives the fourth message sent by the second communication node.

[0120] The fourth message is used to instruct to suspend the transmission of new data between the first communication node and the second communication node.

[0121] S302b. In response to the fourth message, the first communication node suspends transmission of new type data.

[0122] It is understandable that, during the process of transmitting the new type of data, the decision to suspend the transmission of the new type of data may be made by the second communication node, and the decision may be notified to the first communication node.

[0123] In some embodiments, after suspending the transmission of the new type of data, both the first communication node and the second communication node may decide to resume the transmission of the new type of data and notify the other end.

[0124] As a possible implementation, as shown in FIG7 , the above method further includes the following steps:

[0125] S401a: When deciding to resume transmission of new-type data, the first communication node sends a fifth message to the second communication node. Correspondingly, the second communication node receives the fifth message sent by the first communication node.

[0126] The fifth message is used to instruct the resumption of transmission of new data between the first communication node and the second communication node.

[0127] S402a. In response to the fifth message, the second communication node resumes transmitting the new type of data.

[0128] It should be noted that the above steps S401a-S402a can be performed after steps S301a-S302a; or, the above steps S401a-S402a can be performed after steps S301b-S302b, which is not limited in this disclosure.

[0149] For ease of understanding, the data transmission method provided by the present disclosure is described below in the form of examples.

[0150] For example, the first communication node is represented by Node A (Point A), and the second communication node is represented by Node B (Point B). Assuming that Node A is the transmitter of data transmission and Node B is the receiver of data transmission, the data transmission method provided by the present disclosure is described below using Node A and Node B as the trigger sources of the data transmission process as examples.

[0151] Example 1: The sending node A triggers the data transmission process.

[0152] As shown in Figure 11, the Data Transmission (DT) process consists of three phases: preparation phase, initiation phase, and processing phase. The three phases can be implemented as the following steps:

[0167] Phase 3, the processing phase, includes the following steps:

[0168] Sa5. When the second message includes an indication of agreeing to transmit the new type of data, node A enters the DT processing procedure.

[0169] Optionally, when node A enters the DT processing process, it may also start timer T2 to limit the transmission duration of the new type of data.

[0186] Exemplarily, the first message may include at least one of the following: the type of the new type of data to be transmitted, the amount of the new type of data to be transmitted, and the expected time to complete the transmission.

[0192] In some embodiments, if the node B starts the timer T1 when executing step Sb3 , the node B needs to stop the timer T1 when executing step Sb4 .

[0193] Phase 3, the processing phase, includes the following steps:

[0194] Sb5. When the second message includes an indication of agreeing to transmit the new type of data, node A enters the DT processing procedure.
