[0047] Preamble: The preamble signal, also known as the preamble synchronization code, is used to obtain the synchronization position in asynchronous transmission. It is generally located at the beginning of the transmitted signal.

[0048] Midamble: An intermediate synchronization code, or intermediate sequence, is used to correct or align synchronization in the middle of asynchronous transmission. It is usually located in the middle of the transmitted signal.

[0049] Postamble: The postamble, also known as the postamble synchronization code or postamble code, is used to determine the end position in asynchronous transmission. It is generally located at the end of the transmitted signal.

[0050] Device: An IoT device terminal, or IoT device, is used to modulate and transmit the waveform of energy in acquired environmental or radio frequency signals.

[0051] R2D: Reader to Device link, representing the downlink from a network-side device to an IoT device.

[0052] D2R: Device to Reader link, representing the uplink link from an IoT device to a network-side device.

[0053] PRDCH: Physical Reader to Device Channel, the physical layer transmission channel from network-side devices to IoT devices, is the transmission channel on the R2D link used to transmit downlink information.

[0054] PRDCCH: Physical Reader to Device Control Channel, the physical layer control channel from network-side devices to IoT devices.

[0055] PDRCH: Physical Device to Reader Channel, a transmission channel on a D2R link used to transmit uplink information.

[0056] The specific implementation methods of the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0057] like Figure 1 As shown, the system architecture includes: terminal 101 and network device 102; wherein, terminal 101 interacts with network device 103 through network 102.

[0058] Terminal 101 can be referred to as user equipment, terminal equipment, access equipment, user unit, user terminal, or user device, etc. In this embodiment of the disclosure, terminal 101 can also be a terminal device in an IoT system. IoT connects objects to networks, thereby realizing a smart network that enables human-computer interaction and interconnection of things. For example, terminal 101 can be understood as an IoT device, or an IoT device terminal. Specifically, it can be understood as an ambient IoT terminal or a passive IoT device terminal. Terminal 101 can also be referred to as UE (User Equipment).

[0059] In some embodiments, network device 103 may be a base station, relay, or access point, etc. The base station may be, but is not limited to, a 5G or later version base station (e.g., a gNB base station), or a base station in other communication systems (e.g., an eNB base station). It should be noted that the specific type of network-side device is not limited in the embodiments disclosed herein.

[0060] Those skilled in the art will know that Figure 1 The number of terminals and network-side devices shown is merely illustrative; any number of terminals and network-side devices can be used as needed. This disclosure does not limit this.

[0061] As can be seen from the background section, the embodiments of this disclosure are applicable to data transmission of environmental IoT devices, which may also be referred to as IoT devices, IoT terminals, or IoT devices.

[0062] In recent years, IoT has received considerable attention, with more IoT terminals attempting to connect to the network, bringing convenience to life. However, this has also posed challenges to network access capabilities and the energy consumption and cost of devices. The future growth of IoT terminals is expected to be explosive, reaching hundreds of billions. It is impossible to equip all IoT terminals with batteries and perform periodic maintenance and upkeep, as this would lead to very high maintenance costs and serious environmental problems, making it an unacceptable development direction for IoT.

[0063] In light of this, 3GPP proposed the concept of Ambient IoT (A-IoT), which operates without batteries, obtaining power from the environment or radio frequency signals for waveform modulation and transmission. Due to the expectation of low cost, low power consumption, and low complexity, this type of IoT terminal lacks high-quality crystal oscillators, resulting in very poor sampling and timing capabilities. Currently, the 3GPP organization has not yet designed any timing and timeline specifications. Therefore, designing a corresponding Ambient IoT timeline configuration and indication mechanism for this type of IoT terminal to complete the scheduling and communication process of the Ambient IoT system is a problem that needs to be solved.

[0064] In order to at least partially solve the above-mentioned technical problems under the above system architecture, this disclosure provides a data transmission method for IoT devices.

This scheme is generally used when there is an R2D transmission, but the R2D may not trigger a D2R feedback, or the target D2R feedback does not arrive as expected, so multiple R2D transmissions are sent, or multiple R2D transmissions are sent.

[0245] In one specific embodiment, the time interval T from the last time granularity of the previous R2D transmission to the first time granularity of this R2D transmission is... R2D_R2D , can be like Figure 8 As shown.

[0246] like Figure 8 As shown, with Figure 7 Compared to the previous implementation, instead of configuring the earliest and latest R2D and the transmission interval between R2D, T is directly configured or indicated. R2D_R2D The network side considers the time interval to need to be near this value and informs the device of this configuration through configuration or instructions. This scheme is generally used when there is an R2D transmission, but the R2D may not trigger a D2R feedback, or the target D2R feedback does not arrive as expected, so multiple R2D transmissions are sent, or multiple R2D transmissions are sent.

[0247] In one specific embodiment, T R2D Possible components such as Figure 9 As shown.

[0248] like Figure 9 As shown, T R2D It likely consists of three parts. First and foremost, there must be transmission delay, which is an objective fact and is also known as T. R2DThe main components of this delay are as follows: This delay may be predefined or preconfigured, or it may be individually configured based on the device's capabilities or measurement results to meet the accuracy requirements of personalized transmissions and avoid excessively high transmission delays. After experiencing the transmission delay, the D2R transmission is received by the network side. At this point, there may be a processing delay on the network side for decoding the D2R data. However, it may not be separately defined and configured, but rather considered in the transmission preparation delay, i.e., this part of the delay is not considered separately. The third part is the R2D transmission preparation delay, which mainly refers to the time that must be waited between receiving the D2R information and sending the corresponding R2D transmission, including parsing the D2R command and preparing the corresponding information based on the next R2D transmission.

[0249] In one specific embodiment, T R2D_R2D Composition such as Figure 10 As shown. Figure 10 As shown, T R2D_R2D The composition does not involve the transmission delay and processing delay of R2D, so it only includes the transmission preparation delay.
