[0037] The following will be combined with the drawings in the present disclosure to clearly and completely describe the technical solutions in the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0038] It should be noted that, in the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present disclosure should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0039] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0040] In the description of the present disclosure, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "a plurality" means two or more.

[0041] 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) messages. The length of IP messages is usually 1500 bytes (standard Ethernet frame) or 9000 bytes (Jumbo frame). In future wireless communication systems (for example, the sixth generation mobile networks (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 based on IP messages, but AI data, perception data, computing power data, etc. These types of data can be collectively referred to as new data. These new types of data may not come from the application layer, but data generated inside the communication system.

[0042] 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; while 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 reasons, it may not be guaranteed that the data can be successfully transmitted to the other end within the specified time, or the receiving end no longer needs the data during the transmission process, or the sending end can no longer transmit the data, etc., resulting in poor reliability of the new type of data transmission.

[0043] As mentioned in the background technology, in the current wireless communication system, for uplink data transmission, the network schedules through the SR or BSR of the UE; for downlink data transmission, the network schedules 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.

[0044] In response to the above technical problems, the embodiment of the present disclosure provides a data transmission method, the idea of ​​which is that: the first communication node sends a first message to the second communication node for 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 new data between the first communication node and the second communication node. It can be understood that the present disclosure provides a general data transmission process, which can transmit new data after both the sender and the receiver confirm that the new data can be transmitted, so as to ensure the reliability of data transmission.

[0045] The technical solution provided by 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.

[0046] The network architecture of the wireless communication system (including but not limited to 3G, 4G, 5G and future wireless communication systems) in the embodiments 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 with each other through a wireless channel or a wired channel.

[0047] 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.

[0048] It should be understood that in this example, in the downlink, the first communication node may be a network side device (for example, including but not limited to a base station), and the second communication node may be a terminal side device (for example, including but not limited to a terminal device). Of course, in the uplink, the first communication node may also be a terminal side device, and the second communication node may also be a network side device. In the device-to-device communication between the two communication nodes, the first communication node and the second communication node may both be a base station or a terminal device.

[0049] Exemplarily, taking the first communication node as a terminal device and the second communication node as a base station as an example, Figure 1 FIG. 1 is a schematic diagram showing an architecture of a wireless communication system provided by an embodiment of the present disclosure. Figure 1 As shown, the wireless communication system includes a terminal device 110 and a base station 120. The terminal device 110 and the base station 120 perform data transmission via a wireless channel.

[0050] Exemplarily, the terminal device 110 may be a device with wireless transceiver function, which may be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it may also be deployed on the water surface (such as a ship, etc.); it may also be deployed in the air (such as an airplane, a balloon, and a satellite, etc.). The terminal device may be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver function, 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, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in 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 equipment, UE agent or UE device, etc., but the embodiments of the present disclosure are not limited to this.

[0051] 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.

[0052] It should be noted that Figure 1 This is just an exemplary framework diagram. Figure 1 The number of devices included in the Figure 1 In addition to the devices shown, the wireless communication system may also include other devices, such as core network devices.

[0053] 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. It is known to those skilled in the art 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 also applicable to similar technical problems.

[0054] The data transmission method provided by the embodiment of the present disclosure is specifically introduced below.

[0055] The present disclosure provides a data transmission method, such as Figure 2 As shown, the method includes the following steps S201-S202.

[0056] 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.

[0057] The first message is used to request transmission of new type data between the first communication node and the second communication node.

[0058] 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.

[0059] 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.

[0060] 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 with traditional IP packets, the new data takes longer to transmit and may face more problems.

[0061] In some embodiments, the first message includes at least one of the following: the type of new data to be transmitted, the amount of 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.

[0062] 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).

[0063] In some embodiments, when the first communication node sends the first message to the second communication node, the method further includes: starting a timer T1 to limit the retransmission time. Exemplarily, if the first communication node has not received a reply message from the second communication node after the timer T1 times out, 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 the timer T1 times out, the first communication node turns off the timer T1.

[0064] 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.

[0065] Exemplarily, the above-mentioned preset conditions include at least one of the following:

[0066] The amount of new data to be transmitted is less than the data amount threshold;

[0067] The signal quality of the signal received by the first communication node is greater than the signal quality threshold;

[0068] The transmission rate of the channel between the first communication node and the second communication node is greater than the transmission rate threshold.

[0069] Exemplarily, the data volume threshold can be determined based on the expected time to complete the transmission; or, the data volume threshold can also be determined based on the bandwidth used to transmit the data. It can be understood that only when the data volume of the new data is less than the data volume threshold can it be ensured that the new data to be transmitted can be transmitted within the expected time. In addition, when the bandwidth is small, the data volume of the new data to be transmitted also needs to meet the data volume limit corresponding to the bandwidth.

[0070] Exemplarily, the signal quality may be characterized by a reference signal receiving power (RSRP). The signal received by the first communication node may be a reference signal. It is understood that when the signal quality is greater than the 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.

[0071] 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.

[0072] In some embodiments, before the above 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, it can be implemented in the following ways.

[0073] As a possible implementation, Figure 3 As shown, before step S201, the following steps may also be included:

[0074] 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.

[0075] The configuration parameters include at least one of the following: data volume threshold, signal quality threshold, and transmission rate threshold. Exemplarily, configuring the configuration parameters related to data transmission can be implemented as the following process:

[0076] 1. Configure the data volume threshold.

[0077] 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.

[0078] Exemplarily, when the first communication node and the second communication node are UE and base station respectively, the data volume threshold is used for data transmission between UE and base station. The data transmission between UE and base station includes uplink transmission and downlink transmission. For example, for uplink transmission, when the data volume of the new type of data to be transmitted is less than or equal to the data volume threshold, the UE will initiate a data transmission request (for example, the above-mentioned first message); for downlink transmission, when the data volume of the new type of data to be transmitted is less than or equal to the data volume threshold, the base station will schedule the new type of data to be transmitted.

[0079] In some embodiments, the data volume threshold may be a threshold of 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 (Frequency Range, FR) level, cell group level, carrier level, bandwidth part (Bandwidth Part, BWP) level or bearer level parameter.

[0080] 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 specific value can transmit new data.

[0081] The FR level threshold is set based on a specific frequency range. In wireless communication systems, different frequency bands are usually used for different services or different communication technologies. By setting the FR level threshold, you can control which frequency bands are used to transmit new types of data.

[0082] The cell group level threshold is set based on a group of adjacent base stations. In a cellular network, each cell group consists of multiple base stations. The cell group level threshold can be used to control the signal coverage, interference coordination, etc. of these base stations.

[0083] The carrier-level threshold is set based on a specific carrier. Carrier is an important concept in wireless communication, which represents a specific frequency range of the transmitted signal. Therefore, the carrier-level threshold can be set based on a specific carrier. For example, the threshold can be set based on the signal strength or signal-to-noise ratio (SNR) of the carrier to ensure that only carriers that meet specific conditions can be used.

[0084] The BWP level threshold is set based on a specific BWP. BWP is a parameter used to describe the use of frequency bands in wireless communication systems. Therefore, the BWP threshold can be used to control the bandwidth allocation of different services or different users within the frequency band.

[0085] The bearer-level threshold is set based on a specific bearer. A bearer is a parameter used to describe the service load in wireless communications. The bearer-level threshold can be used to control the priority of different services, flow control, etc.

[0086] Exemplarily, 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.

[0087] 2. Configure the signal quality threshold.

[0088] Configuring the signal quality threshold refers to configuring the signal quality of the current network to allow the new data transmission. For example, the signal quality may be RSRP.

[0089] Exemplarily, when the first communication node and the second communication node are UE and base station respectively, the signal quality threshold is used for data transmission between UE and base station. The transmission between UE and base station includes uplink transmission and downlink transmission. For example, for uplink transmission, when the current RSRP of UE is higher than the signal quality threshold, UE will initiate a data transmission request (for example, the first message mentioned above); for downlink transmission, when the base station determines that the current RSRP of UE is higher than the signal quality threshold, the base station will schedule new data to be transmitted.

[0090] In some embodiments, the signal quality threshold may be a threshold of 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.

[0091] 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.

[0092] 3. Configure the transmission rate threshold.

[0093] Configuring the transmission rate threshold refers to configuring the rate at which the current network allows new data to be transmitted, that is, when the transmission rate of the channel between the first communication node and the second communication node is greater than the data volume threshold, the transmission of new data is allowed.

[0094] 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 UE and base station. Among them, uplink transmission and downlink transmission are included between UE and base station. 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).

[0095] In some embodiments, the transmission rate threshold may be a threshold of 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.

[0096] Exemplarily, if the transmission rate threshold is configured as a bearer level, a higher transmission rate threshold may be configured for a guaranteed bit rate (GBR) bearer.

[0097] In some embodiments, multiple transmission rate thresholds may be configured, and different transmission rate thresholds may correspond to different data sizes.

[0098] 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.

[0099] As another possible implementation, Figure 4 As shown, before the above step S201, the following steps may also be included:

[0100] S200b, the second communication node sends the 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] The second message is used to indicate whether to transmit new type of data between the first communication node and the second communication node.

[0105] In some embodiments, the second message includes one of the following:

[0106] Indication of consent to the transfer of new types of data;

[0107] Instructions to refuse the transmission of new types of data;

[0108] An indication to hold off on transmission of new types of data.

[0109] 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.

[0110] The description of the preset conditions can be referred to step S201, which will not be repeated here.

[0111] 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 agreeing to transmit the new type of data, or an indication of suspending the 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 refusing to transmit the new type of data, or an indication of suspending the transmission of the new type of data.

[0112] In some embodiments, the second message may be in any of the following transmission forms: RRC signaling, MAC CE, DCI, UCI, PDU. It is understandable that the transmission form of the second message does not depend on the transmission form of the first message.

[0113] It can be understood that based on the data transmission method provided by the embodiment of the present disclosure, the first communication node can send a first message to the second communication node for 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 new data between the first communication node and the second communication node. In this way, after both the sender and the receiver confirm that the new data can be transmitted, the new data can be transmitted to ensure the reliability of data transmission.

[0114] 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.

[0115] 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.

[0116] In some embodiments, when the transmission of the new data begins, timer T2 is started to limit the transmission time of the new data. For example, if the transmission of the new data is not completed after timer T2 times out, it means that the actual transmission time of the new data exceeds the expected transmission time.

[0117] In some embodiments, after the new type of data transmission is completed, the peer end is notified that the data transmission has been completed, and the timer T2 is stopped.

[0118] In some embodiments, when starting to transmit a new type of data, the first packet of data to be transmitted includes an indication of starting to transmit the data.

[0119] In some embodiments, during the transmission of new types of 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 types of data and notify the other end.

[0120] As a possible implementation, Figure 5As shown, after step S202, the method further includes the following steps:

[0121] S301a: In the process of transmitting 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.

[0122] The third message is used to instruct to suspend the transmission of new data between the first communication node and the second communication node.

[0123] S302a. In response to the third message, the second communication node suspends transmission of new types of data.

[0124] It can be understood that, during the process of transmitting the new type of data, the decision to suspend the transmission of the new type of data can be made by the first communication node, and the decision can be notified to the second communication node.

[0125] As another possible implementation, Figure 6 As shown, after step S202, the method further includes the following steps:

[0126] S301b: In the process of transmitting 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.

[0127] The fourth message is used to instruct to suspend the transmission of new types of data between the first communication node and the second communication node.

[0128] S302b. In response to the fourth message, the first communication node suspends transmission of new types of data.

[0129] It can be understood that, during the process of transmitting the new type of data, the decision to suspend the transmission of the new type of data can be made by the second communication node, and the decision can be notified to the first communication node.

It can transmit new types of data with a large amount of data generated within the system (for example, AI data, perception data, computing power data, etc.), and can ensure the reliability of data transmission.

[0156] For ease of understanding, the data transmission method provided by the present disclosure is described below in the form of examples.

[0157] Exemplarily, the first communication node is represented by node A (PointA), and the second communication node is represented by node B (PointB). Assuming that node A is the sending end of data transmission and node B is the receiving end of data transmission, the data transmission method provided by the present disclosure is described below by taking the trigger sources of the data transmission process as node A and node B as examples.

[0158] Example 1: The sending node A triggers the data transmission process.

[0159] like Fig.11 As shown, the data transmission (DT) process includes three stages: preparation stage, initiation stage and processing stage. The three stages can be implemented as the following steps:

[0160] Phase 1, the preparation phase, includes the following steps:

[0161] Sa1. Configure the configuration parameters related to data transmission.

[0162] The configuration parameters include at least one of the following: data volume threshold, signal quality threshold, and transmission rate threshold.

[0163] Phase 2, the initiation phase, includes the following steps:

[0164] Sa2: When data transmission is required, node A determines whether a DT process can be initiated.

[0165] Sa3. When the DT process can be initiated, node A sends a first message to node B and starts timer T1.

[0166] The first message includes a data transmission request (DT request), which is used to request transmission of new data between node A and node B.

[0167] 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.

[0174] Phase 3, the processing phase, includes the following steps:

[0175] Sa5. When the second message includes an indication of agreeing to transmit the new type of data, node A enters the DT processing procedure.

[0176] Optionally, when node A enters the DT processing process, timer T2 may be started to limit the transmission duration of the new type of data.

[0177] Sa6. Node A transmits new data to node B.

[0178] Node A may indicate the start of data transmission (Start DT) in the first packet data sent to node B.

[0179] In some embodiments, during the transmission of new data, both node A and node B may control the DT process (including pausing the DT process, resuming the DT process, terminating the DT process, etc.). Exemplarily, the following steps may be included:

[0180] Sa7-1. Node A or node B decides to temporarily suspend the DT process according to the processing strategy, and sends an instruction to suspend data transmission (Suspend DT) to the other end.

[0181] Sa7-2. Node A or node B decides to resume the DT process according to the processing strategy, and sends an instruction to resume data transmission (Resume DT) to the other end.

[0182] Sa7-3. Node A or node B decides to terminate the DT process according to the processing strategy and sends an indication of terminating data transmission (End DT) to the other end.

[0183] Sa8. After the new type of data transmission is completed, node A sends an indication of data transmission completion (Complete DT) to node B.

[0184] In some embodiments, if node A starts timer T2 when executing step Sa5, node A needs to stop timer T2 when executing step Sa8.

[0185] Example 2: The receiving end node B triggers the data transmission process.

[0189] Phase 2, the initiation phase, includes the following steps:

[0190] Sb2. When data transmission is required, Node B determines whether a DT process can be initiated.

[0191] Sb3. When the DT process can be initiated, node B sends a first message to node A and starts timer T1.

[0192] The first message includes a data transmission request (DT request), which is used to request transmission of new data between node A and node B.

[0193] 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.

[0198] Exemplarily, the second message may be RRC signaling, MAC CE, UCI, DCI or special data PDU, etc.

[0199] In some embodiments, if the node B starts the timer T1 when executing step Sb3, then when executing step Sb4, the node B needs to stop the timer T1.

[0200] Phase 3, the processing phase, includes the following steps:

[0201] Sb5. When the second message includes an indication of agreeing to transmit the new type of data, node A enters the DT processing procedure.

[0202] Optionally, when node A enters the DT processing process, timer T2 may be started to limit the transmission duration of the new type of data.

[0203] Sb6. Node A transmits new data to node B.

[0204] Node A may indicate the start of data transmission (Start DT) in the first packet data sent to node B.

[0205] In some embodiments, during the transmission of new data, both node A and node B may control the DT process (including pausing the DT process, resuming the DT process, terminating the DT process, etc.). Exemplarily, the following steps may be included:
