[0002] This disclosure claims priority to Chinese Patent Application No. 202411529968.3, filed in China on October 30, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of wireless communication technology, and in particular to a data transmission method, apparatus, electronic device, and computer program product. Background Technology

[0004] The Ambient Internet of Things (AIoT) is an innovative technological concept introduced to achieve the interconnection of everything. AIoT is an extension of the passive Internet of Things (IoT). AIoT communicates by collecting energy from the environment, such as light, heat, mechanical vibration, and electromagnetic waves, requiring no power source or battery, making it suitable for low-cost, low-maintenance IoT devices. AIoT includes two main scenarios:

[0005] 1. AIoT devices and network devices transmit data via an air interface connection (as shown in Figure 1(A));

[0006] 2. AIoT devices and intermediate devices are connected via an air interface, and the intermediate devices then forward the data to the network devices (as shown in Figure 1(B)).

[0007] In scenario 2, the intermediate device can be in the Radio Resource Control (RRC) idle state (RRC_IDLE), connected state (RRC_CONNECTED), or inactive state (RRC_INACTIVE). When the intermediate user equipment (UE) has data to transmit, it will trigger a transition from RRC_INACTIVE to RRC_CONNECTED, which usually introduces a certain delay.

[0008] In related technologies, terminal devices in the RRC inactive state can initiate downlink small data transmission (DL SDT) and uplink small data transmission (UL SDT), but only for the transmission of terminal data and location information. Summary of the Invention

[0047] To make the objectives, technical solutions, and advantages of this disclosure more apparent, exemplary embodiments according to this disclosure will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this disclosure, and not all embodiments of this disclosure. It should be understood that this disclosure is not limited to the exemplary embodiments described herein.

[0048] First, let’s take a look at the application scenarios according to the embodiments of this disclosure with reference to FIG1.

[0049] Figure 1 is a schematic diagram illustrating a passive Internet of Things (IoT) data or signaling transmission scenario according to an embodiment of this disclosure. The signal transmission method provided in this disclosure can be applied to various communication systems, such as Long Term Evolution (LTE) systems, 5th Generation (5G) mobile communication systems, future communication systems, or systems integrating multiple communication systems, etc., and this disclosure does not limit the application to these systems. 5G can also be referred to as New Radio (NR). The communication system provided in this disclosure can be a public land mobile network (PLMN), a device-to-device (D2D) network, a machine-to-machine (M2M) network, an Internet of Things (IoT) network, or other networks.

[0050] As shown in Figure 1, the scenarios can be divided into the following two types.

[0051] Scenario 1 (as shown in Figure 1(A)): A common direct connection scenario, which may include network devices (e.g., base station 13) and passive IoT devices (e.g., tag 11).

[0052] In this scenario, passive IoT devices directly transmit data and signaling to base station 13 via specific air interface technology (such as the Uu interface). The Uu interface is the wireless interface between user equipment (e.g., tag 11 and / or intermediate UE 12) and base station 13, also known as the air interface. In areas with good base station signal coverage, this connection method enables efficient data transmission, meeting the needs of applications such as environmental monitoring.

[0053] However, not all areas have good base station signal coverage. When tag 11 is in an area with weak base station signal coverage or cannot be directly connected to a base station, scenario 2 can be used to expand the coverage area.

[0054] Scenario 2 (as shown in Figure 1(B)): This scenario may include: network devices (e.g., base station 13), passive IoT devices (e.g., tag 11), and intermediate devices (e.g., intermediate UE 12). By establishing a connection with the intermediate UE 12, the intermediate node forwards the data to the base station.

[0055] It should be noted that in the embodiments disclosed herein, the intermediate device can be a UE, for example, the intermediate device can be a terminal with reader / writer capabilities.

[0056] It should be noted that the network devices in this disclosure embodiment may include macro base stations and micro base stations. Specifically, macro base stations may include Next Generation NodeBs (gNBs), and micro base stations may include pole stations. In addition to macro base stations or micro base stations as described in this disclosure embodiment, the network devices may also include readers, transmission receive points (TRPs), transmission points (TPs), transmission reception points (TRPs), evolved Node B (eNB) radio network controllers (RNCs), Node Bs (NBs), base station controllers (BSCs), base transceiver stations (BTSs), home base stations (e.g., home evolved NodeBs or home Node Bs (HNBs), base band units (BBUs), and relays. In this disclosure embodiment, the device used to implement the functions of the network device may be the network device itself, or it may be a device capable of supporting the network device in implementing that function, such as a chip system, which can be installed in the network device for matching and use.

[0057] The passive IoT device in this disclosure may specifically include active tags, semi-passive tags, and passive tags, or it may be a device that enables the passive IoT device to achieve this function, such as a chip system, which can be installed in the passive IoT device for matching and use.

[0058] The intermediate device in the embodiments of this disclosure can be a user's mobile device, such as a smartphone or tablet, or a dedicated relay device; this disclosure does not impose any specific limitations.

[0059] Specifically, the data transmission method of the present disclosure is applied to the above-mentioned Scenario 2. Under the architecture of the passive Internet of Things, the intermediate UE12 can act as a reader / writer. After receiving passive Internet of Things signaling (e.g., inventory signaling, command signaling, etc.) from the network (which can be the base station 13 or the core network 14), it initiates inventory or command signaling for the tag 11; then receives response information (e.g., tag ID, signaling feedback) from the tag 11 and forwards it to the network. The amount of data exchanged in this process is relatively small. Therefore, the present disclosure proposes a data transmission method. By enabling the intermediate UE to use small packet data transmission in the AIoT architecture, the intermediate UE can always be in the RRC_INACTIVE state and transmit AIoT-related data, thereby avoiding the latency caused by RRC state transitions and reducing signaling overhead and power consumption. Specific details will be further described in detail with reference to FIGS. 2 - FIG. 5.

[0060] FIG. 2 is a flowchart illustrating a data transmission method according to an embodiment of the present disclosure. As shown in FIG. 2, the data transmission method applied to a UE (or described as an intermediate device, or intermediate UE) may at least include the following steps.

[0061] In step S201, a first message is sent, where the first message includes first passive Internet of Things signaling response information, and the first passive Internet of Things signaling response information is transmitted based on small packet data-related resources. As described above, the first passive Internet of Things signaling response information may be feedback information for signaling such as inventory and command. Inventory refers to counting and identifying tags 11 connected to the Internet of Things system (e.g., by sending a specific signal, the system attempts to determine which devices are online, in what state, and their basic attribute information, etc.); a command may be to require the tag 11 to perform a specific operation, such as collecting data, adjusting parameters, starting, reading / writing, or stopping a certain function, etc. Its data volume is usually small (<9600038>.423) and can be transmitted through small packet data-related resources (e.g., Data Radio Bearer (DRB), Signaling Radio Bearer (SRB), etc.), thereby achieving the effect of preventing the intermediate UE from entering the RRC_CONNECTED state. Specific details will be further described in detail in the overall process with reference to FIGS. 4 and FIG. 5.

[0062] FIG. 3 is a flowchart further illustrating a data transmission method according to an embodiment of the present disclosure. As shown in FIG. 3, the data transmission method applied to a base station may at least include the following steps.

[0063] In step S301, a first message is received, wherein the first message includes first passive IoT signaling response information, wherein the first passive IoT signaling response information is transmitted based on small packet data related resources. As described above, this step is the opposite step to step S201. Similarly, the specifics will be further described in detail in the overall process with reference to Figures 4 and 5.

[0064] Figure 4 is an overall flowchart illustrating a data transmission method according to an embodiment of the present disclosure. As shown in Figure 4, the execution entity of the data transmission method in this embodiment may include at least: tag 11, intermediate UE 12, base station 13, and core network 14. Figure 4 shows the overall process of mobile terminal receiving small data transmission (Mobile Terminated Small Data Transmission, MT-SDT). MT-SDT can be understood as a specific manifestation of DL-SDT in mobile terminal application scenarios. Both are downlink small packet data transmissions, but MT-SDT is specifically designed for scenarios where mobile terminals (i.e., intermediate UEs in this disclosure) receive data.

[0065] It should be noted that the middle UE12 in RRC_INACTIVE in Figure 4 is within the coverage area of ​​the SDT-configured base station 13 (i.e., it is not affected by the Xn interface), and its process may include the following steps.

[0066] 4.1 The core network 14 initiates a paging process, which includes signaling such as inventory or command. After receiving the paging process, the base station 13 caches the signaling such as inventory or command, including the type of inventory or command signaling message, possible tag identifiers, number of tags, etc.

[0067] 4.2 Base station 13 sends a second message to intermediate UE 12. Intermediate UE 12 can be selected by core network 14 and / or base station 13. Specifically, when intermediate UE 12 is in RRC_INACTIVE mode and supports DL SDT and UL SDT, base station 13 sends a paging message (i.e., the second message) to intermediate UE 12. The second message carries both a small packet data transmission indication (e.g., MT-SDT indicator, MT-SDT data size) and a first passive IoT signaling (e.g., AIoT indication information, optionally including message type, such as inventory or instruction, and tag identifier, tag quantity, etc.). Intermediate UE 12 can obtain the information used in step 4.3 for intermediate UE 12 to determine whether to initiate the MT-SDT procedure. For example, if the number of tags to be inventoried is 10,000, compared to 10 tags, the uplink transmission requirement is higher. The terminal may consider initiating an RRC recovery request.

[0068] 4.3. UE12 determines the initialization conditions and initiates the MT-SDT procedure; it then sends an RRC recovery request message. The RRC recovery request message contains inventory or command indication information, optionally including message type, tag identifier, and tag quantity.

[0069] It should be noted that the RRC recovery request originally requested to restore RRC_INACTIVE to RRC_CONNECTED. However, because the RRC recovery request message includes AIoT indication information such as inventory or instructions, it essentially informs the network that the reason for initiating this SDT process is AIoT service, rather than the intermediate UE12 having uplink data transmission needs. As mentioned above, the AIoT data volume is relatively small, so the intermediate UE12 will not subsequently enter RRC_CONNECTED, and will continue to transmit data based on small packet data-related resources while maintaining RRC_INACTIVE.

[0070] 4.4 Base station 13 sends a seventh message to intermediate UE 12, wherein the seventh message includes a first passive IoT signaling (e.g., including inventory or instruction indication information, optionally including message type, tag identifier, tag quantity, etc.), the first passive IoT signaling is transmitted based on small packet data related resources (e.g., DRB or SRB for MT-SDT), wherein the DRB or SRB for MT-SDT is a data or signaling radio bearer pre-configured by the network for small packet transmission.

[0071] 4.5-4.7 The intermediate UE12 executes the inventory process or executes instructions. Specifically, the intermediate UE12 sends a third message to the tag 11, wherein the third message includes a first passive IoT signaling (e.g., the third message is a paging message, and the first passive IoT signaling may include inventory or command signaling, such as inventory or command signaling message type, possible tag identifier, number of tags, etc.); the intermediate UE12 and the tag 11 perform random access operations to complete the inventory or command signaling; the tag 11 then sends a fourth message to the intermediate UE12, wherein the fourth message includes first passive IoT signaling response information (e.g., device-related information (e.g., tag ID, etc.) and / or signaling feedback (acknowledgement) related information).

[0072] 4.8. The intermediate UE 12 sends a first message to the base station 13, wherein the first message includes a first passive IoT signaling response information, wherein the first passive IoT signaling response information is transmitted based on small packet data related resources. Specifically, the first passive IoT signaling response information is the information received from tag 11 in step 4.7 (tag ID and / or Acknowledge, etc.). The small packet data related resources in this step can be DRB or SRB for Mobile-Originated Small Data Transmission (MO-SDT) initiated by the mobile terminal. MO-SDT can be understood as a specific manifestation of UL-SDT in the mobile terminal application scenario. Both are uplink small packet data transmissions. MO-SDT is specifically for the scenario where the mobile terminal (i.e., the intermediate UE in this disclosure) sends data.

[0073] 4.9 Base station 13 sends the first passive IoT signaling response information (tag ID and / or Acknowledge, etc.) received from intermediate UE 12 to core network 14.

[0074] 4.10 The core network 14 sends a fifth message to the intermediate UE 12 via the base station 13. The fifth message includes a second passive IoT signaling (e.g., inventory signaling, command signaling, etc.). The second passive IoT signaling is transmitted based on small packet data related resources (e.g., DRB or SRB for MT-SDT).

[0075] 4.11. The intermediate UE12 executes the inventory process or executes instructions. Tag 11 sends a second passive IoT signaling response information (e.g., tag ID and / or Acknowledge, etc.) to the intermediate UE12.

[0076] 4.12. The intermediate UE12 sends a sixth message to the core network 14 via the base station 13. The sixth message includes a second passive IoT signaling response information (e.g., tag ID and / or Acknowledge, etc.). The second passive IoT signaling response information is transmitted based on small packet data related resources (e.g., DRB or SRB for MO-SDT).

[0077] It should be noted that because AIoT transmits small amounts of data and requires no or at most one subsequent data transmission, steps 4.10-4.12 above are optional.

[0078] 4.13. Base station 13 sends an RRC release message to intermediate UE 12.

[0079] This concludes the description of the downlink transmission process of UE12 in RRC_INACTIVE within the coverage area of ​​SDT-configured base station 13 (i.e., without the influence of the Xn interface).

[0080] Furthermore, if UE12 in the RRC_INACTIVE state is outside the coverage area of ​​SDT-configured base station 13 (i.e., affected by the Xn interface), the Xn interface is responsible for the connection between base stations. Specifically, base station 13 sends an Acquire User Equipment Context Request message to the upper serving base station 13' to obtain information such as small packet data transmission indication (e.g., SDT indication) and first passive IoT signaling (e.g., AIoT indication information, optionally including message type, such as inventory or instruction, and tag identifier, tag quantity, etc.).

[0081] Figure 5 is an overall flowchart illustrating a data transmission method according to another embodiment of the present disclosure. As shown in Figure 5, the execution entities of the data transmission method in this embodiment may include at least: tag 11, intermediate UE 12, base station 13, and core network 14. Figure 5 shows the overall flow of MO-SDT. It should be noted that the intermediate UE 12 in RRC_INACTIVE in Figure 5 is within the coverage area of ​​the SDT-configured base station 13 (i.e., it is not affected by the Xn interface), and its flow may include the following steps.

[0082] 5.1 The core network 14 sends a second message to the intermediate UE12 in RRC_CONNECTED, wherein the second message may be a paging message and may include a first passive IoT signaling (such as inventory or command signaling).

[0083] It should be noted that this message may be non-real-time. The UE12 waits for (pending) the message and performs inventory or executes instructions after a certain delay or under certain conditions (e.g., periodically).

[0084] 5.2 Base station 13 sends an eighth message to intermediate UE, wherein the eighth message is used to release the RRC connection of intermediate UE12, so that intermediate UE12 enters the RRC_INACTIVE state, which includes suspend information.

[0085] 5.3-5.5 The intermediate UE12 executes the inventory process or executes instructions. Specifically, the intermediate UE12 sends a third message to the tag 11, wherein the third message includes a first passive IoT signaling (e.g., the third message may be a paging message, and the first passive IoT signaling may include inventory or command signaling, such as inventory or command signaling message type, possible tag identifier, number of tags, etc.); the intermediate UE12 and the tag 11 perform random access operations to complete the inventory or command signaling; the tag 11 then sends a fourth message to the intermediate UE12, wherein the fourth message includes first passive IoT signaling response information (e.g., device-related information (e.g., tag ID, etc.) and / or signaling feedback (Acknowledge) related information).

[0086] 5.6. The intermediate UE 12 initiates the UL-SDT procedure, that is, sends an RRC recovery request and a first message to the base station 13. The RRC recovery request includes inventory or instruction indication information. The first message includes the first passive IoT signaling response information (tag ID and / or Acknowledge, etc.) and is transmitted based on small packet data related resources (such as DRB or SRB for MO-SDT).

[0087] 5.7 Base station 13 sends the first passive IoT signaling response information (tag ID and / or Acknowledge, etc.) received from intermediate UE 12 to core network 14.

[0088] 5.8 The core network 14 sends a fifth message to the intermediate UE 12 via the base station 13. The fifth message includes a second passive IoT signaling (e.g., inventory signaling, command signaling, etc.). The second passive IoT signaling is transmitted based on small packet data related resources (e.g., DRB or SRB for MT-SDT).

[0089] 5.9 The intermediate UE12 executes the inventory process or executes instructions. Tag 11 sends a second passive IoT signaling response information (e.g., tag ID and / or Acknowledge, etc.) to the intermediate UE12.

[0090] 5.10. The intermediate UE12 sends a sixth message to the core network 14 via the base station 13. The sixth message includes a second passive IoT signaling response information (e.g., tag ID and / or Acknowledge, etc.). The second passive IoT signaling response information is transmitted based on small packet data related resources (e.g., DRB or SRB for MO-SDT).

[0091] It should be noted that because AIoT transmits small amounts of data and requires no or at most one subsequent data transmission, steps 5.8-5.10 above are optional.

[0092] 5.11. Base station 13 sends an RRC release message to intermediate UE 12.

[0093] This concludes the description of the uplink transmission process of UE12 in RRC_INACTIVE within the coverage area of ​​SDT-configured base station 13 (i.e., without the influence of the Xn interface).

[0094] Furthermore, if UE12 in the RRC_INACTIVE state is outside the coverage area of ​​SDT-configured base station 13 (i.e., affected by the Xn interface), specifically, base station 13 sends an Acquire User Equipment Context Request message to the next serving base station 13' to acquire information such as small packet data transmission indication (e.g., SDT indication) and first passive IoT signaling (e.g., AIoT indication information, optionally including message type, such as inventory or instruction, and tag identifier, tag quantity, etc.).
