[0242] Figure 1A is a schematic diagram illustrating the architecture of a communication system according to an embodiment of the present disclosure. As shown in Figure 1A, communication system 100 may include a first device and a second device. The first device may be an IoT device; the second device may be a network device; or the second device may be an intermediate node between the network device and the first device, the intermediate node being used to facilitate communication between the first device and the network device, and the intermediate node may be, for example, a terminal. Furthermore, the network device may include at least one of an access network device and a core network device.

[0245] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0246] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0247] In some embodiments, the core network device may be a device including one or more network elements, or may be multiple devices or a group of devices, each including all or part of one or more network elements. The network element may be virtual or physical. The core network, for example, includes at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC). Alternatively, the core network device may also be a location management function network element.

[0248] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0249] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0250] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile Communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0251] Alternatively, to enable battery-free IoT communication, a new low-power Ambient Internet of Things (A-IoT) device has been introduced. This new A-IoT device does not require batteries, nor does it need to generate its own energy. Instead, it can harvest energy from the outside world, such as from the surrounding environment or signals sent by surrounding devices, and can communicate based on the harvested energy.

[0252] Optionally, the above-mentioned A-IoT device can communicate with the terminal and / or network device based on the energy collected from the outside world. Specifically, in some embodiments, the terminal and / or network device can send a signal to the A-IoT device. After receiving the signal, the A-IoT device can send corresponding response information to the terminal and / or network device or perform corresponding operations. Among them, when the A-IoT device sends response information to the terminal and / or network device, it can be sent in a backscatter working mode or in an active sending working mode. Optionally, the above-mentioned "backscatter working mode" can be, for example: the terminal and / or network device sends an electromagnetic wave (continuous wave, CW) signal to the A-IoT device, and the A-IoT device adjusts the matching between the receiving antenna and the impedance according to the information to be sent, enhances the reflection of the incident CW signal, and modulates the perception data obtained by itself onto the reflected signal to complete the transmission of the data, thereby realizing backscatter communication. Optionally, the above-mentioned "active transmission working mode" can be understood as, for example: actively generating signals and actively sending signals without CW signal excitation, wherein the A-IoT device can actively generate signals and actively send signals based on its stored energy, and the energy stored in the A-IoT device can be the energy that the terminal and / or network device pre-charges the A-IoT device.

[0253] Optionally, the aforementioned A-IoT devices may include multiple different types of devices, such as first type A-IoT devices and second type A-IoT devices, wherein different types of A-IoT devices have different corresponding capabilities.

[0254] Optionally, the above-mentioned first type A-IoT device has energy storage capability, but does not have independent signal generation and / or amplification capability, and its uplink transmission relies on backscatter transmission; that is, the first type A-IoT device needs to use the backscatter working mode to send signals to the terminal and / or network device (such as the aforementioned response information), which has the lowest complexity and cost and very low power consumption.

[0255] Optionally, the above-mentioned second type A-IoT device has energy storage capability and independent signal amplification capability, and its uplink transmission can be based on internally generated signals, or its uplink transmission can rely on backscatter transmission; that is, the second type A-IoT device can actively send signals to the terminal and / or network device based on the internally generated signal, or the second type A-IoT device can use the backscatter working mode to send signals to the terminal and / or network device.

[0256] Optionally, the above-mentioned A-IoT device can be applied to a variety of different communication architectures in the communication system, wherein Figures 1B-1F are schematic diagrams of the architecture when the A-IoT device communicates with network devices and / or terminals according to an embodiment of the present disclosure. Optionally, as shown in Figure 1B, the A-IoT device (i.e., the Ambient IoT device in Figure 1B) and the network device (such as a base station (BS)) can directly receive and send data.

[0257] Optionally, as shown in FIG1C , data can be received and sent indirectly between the A-IoT device and the network device (such as a base station (BS)) through an intermediate node, where the intermediate node can be, for example, a relay, an integrated access backhaul (IAB) device, a terminal, or a repeater.

[0258] Optionally, as shown in FIG1D , uplink data can be directly transmitted between the A-IoT device and the network device (such as a base station (BS)), and downlink data can be indirectly transmitted between the A-IoT device and the network device (such as a base station (BS)) through an intermediate node, which can be, for example, a relay, an IAB device, a terminal, or a repeater.

[0259] Optionally, as shown in FIG1E , downlink data can be directly transmitted between the A-IoT device and the network device (such as a base station (BS)), and uplink data can be indirectly transmitted between the A-IoT device and the network device (such as a base station (BS)) through an intermediate node.

[0260] Optionally, as shown in FIG1F , data can be directly received and sent between the A-IoT device and the terminal (or user equipment (UE)). The terminal can be responsible for collecting data from the A-IoT device and forwarding the collected data to the network device.

[0261] Based on the above, when an A-IoT device needs to send data to a terminal and / or network device, if no resources are currently available, how to request resources becomes a pressing issue. Furthermore, given the small memory, low processing power, lack of battery, low data transmission, and massive deployment characteristics of A-IoT devices, resource requests in A-IoT scenarios typically require comprehensive consideration of latency and signaling overhead. Furthermore, since A-IoT supports multiple device types, and different types of A-IoT devices have different capabilities, the device type also needs to be considered when requesting resources.

[0262] FIG2A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:

[0263] Step 2101: The first device determines that there is data to be sent.

[0264] Optionally, the data to be sent may be data to be sent by the first device to the network device.

[0265] In some embodiments, the above-mentioned "the first device determines that there is data to be sent" may, for example, be: when the first device determines that data needs to be sent but there are no available resources for sending the data, at this time, the first device may determine that there is data to be sent. Also, by way of example, the above-mentioned "the first device determines that data needs to be sent" may, for example, be: when the first device senses a change in ambient temperature, pressure, or humidity, etc., and needs to report sensor data to the network device, at this time, the first device determines that there is a need to actively send data.

[0266] Step 2102: The first device determines a first resource and / or a first channel.

[0267] Optionally, the first resource may be a resource used by the first device when indicating that the first device has data to be sent, and the first channel may be a channel used by the first device when indicating that the first device has data to be sent. The first device may request a resource "for sending the data to be sent" through the first resource and / or the first channel. Optionally, the first resource and / or the first channel may be similar to a Scheduling Request (SR) resource in a new radio (NR) system. Furthermore, the first resource may, for example, include: at least one of a time domain resource, a frequency domain resource, and a code domain resource;

[0268] In some embodiments, the method for the first device to determine the first resource and / or the first channel may include: the first device obtains a first configuration, and the first configuration can be used to configure one or more first resources and / or first channels; and the first device can determine the first resource and / or the first channel based on the first configuration. The first configuration can be obtained by the first device based on the configuration of the network device. For example, the network device can configure the first configuration through instructions, commands, signaling, etc.; for example, the network device can configure the first configuration through dedicated radio resource control (RRC) signaling. Alternatively, the first configuration can be obtained by the first device based on protocol provisions; or, the first configuration can be obtained by the first device based on pre-configuration. Of course, the first device can also obtain the first configuration in other ways. The present disclosure does not specifically limit how the first device obtains the first configuration.

[0269] It should be noted that in some embodiments, the first configuration can be configured at the device type granularity of the first device. Specifically, as described previously in the embodiment of FIG2A , the first device includes multiple device types, such as a first type A-IoT device and a second type A-IoT device. For detailed descriptions of the first type A-IoT device and the second type A-IoT device, please refer to the previous description of the embodiment of FIG2A . Furthermore, if the first device includes multiple device types, the first resources and / or first channels corresponding to different types of first devices can be the same or different. For example, a first type A-IoT device and a second type A-IoT device can share the same first resource and / or first channel, or the first resource and / or first channel corresponding to the first type A-IoT device can be different from or partially overlap with the first resource and / or first channel corresponding to the second type A-IoT device. For another example, the device type of the first device can be "backscatter" or "non-backscatter," where "backscatter" can, for example, refer to transmitting signals based on backscatter, and "non-backscatter" can, for example, refer to actively transmitting signals. Furthermore, the first resource and / or first channel can be classified according to "backscatter" and "non-backscatter". For example, the first resource and / or first channel corresponding to the first device of the "backscatter" category may be different from or partially overlap with the first resource and / or first channel corresponding to the first device of the "non-backscatter" category; or, the first device of the "backscatter" category and the first device of the "non-backscatter" category may share the same first resource and / or first channel. It should be noted that the device type mentioned above is only an example, and there may be other forms of naming device types, which are not specifically limited in this disclosure.

[0270] Step 2103: The first device sends a first signal on a first resource and / or a first channel.

[0271] Optionally, the first signal may be used to indicate that the first device has data to be sent, and the first signal may be received by the second device.

[0272] Optionally, the first signal may be an energy pulse signal. When the first signal is an energy pulse signal, the first device may indicate that the first device has data to be sent by the action of "sending an energy pulse signal on the first resource and / or the first channel", and when the second device receives the energy pulse signal on the first resource and / or the first channel, the second device may determine that the first device corresponding to the first resource and / or the first channel has data to be sent. Alternatively, in other embodiments, the first signal may include indication information, and the indication information is used to indicate that the first device has data to be sent. And, when the second device receives the indication information on the first resource and / or the first channel, the second device may determine that the first device corresponding to the first resource and / or the first channel has data to be sent. The indication information may be, for example, an N-bit value, where N is a positive integer, and when the N-bit value is a first value (such as 1), it may indicate that the first device has data to be sent, and when the N-bit value is a second value (such as 0), it may indicate that the first device has no data to be sent. The indication information mentioned above is only an example, and there may be other indication methods, which are not specifically limited in the present disclosure.

[0273] Furthermore, in some embodiments, when the first device is different, the method of sending the first signal may also be different.

[0274] Optionally, if the first device communicates based on “backscatter”, the step of the first device sending the first signal on the first resource and / or the first channel may include:

[0275] Step 2103a: Receive a second signal sent by the second device.

[0276] Optionally, the second device may be a network device; or, the second device may be an intermediate node between the network device and the first device, and the intermediate node may be used to implement communication between the first device and the network device. Wherein, the first device mentioned above may be the A-IoT device (or referred to as a low-power device, a low-power environment IoT device, etc.) described before the embodiment of Figure 2A. For a detailed introduction to the A-IoT device, please refer to the description before the embodiment of Figure 2A. And, when the second device is an intermediate node between the network device and the first device, the second device may be, for example, the intermediate node (intermediate node) in Figures 1C to 1E, the terminal in Figure 1F, etc. Wherein, for a detailed introduction to the intermediate node (intermediate node) in Figures 1C to 1E and the terminal in Figure 1F, please refer to the description before the embodiment of Figure 2A.

[0277] Optionally, in some embodiments, the second device may transmit the second signal to the first device, and the first device may receive the second signal. Furthermore, the second signal may be used by the first device to perform backscatter communication. For example, the second signal may be the CW signal described previously in the embodiment of FIG. 2A . A detailed description of the CW signal may be found in the previous description of the embodiment of FIG. 2A .

[0278] It should be noted that when the second device is a different device, the corresponding communication architecture of the embodiment of Figure 2A will also be different. Specifically, when the second device is the aforementioned network device, the current communication architecture is the communication architecture shown in Figure 1B; when the second device is the aforementioned intermediate node or terminal, the current communication architecture is any of the communication architectures shown in Figures 1C-1F.

[0279] Step 2103b: Perform backscattering on the first resource and / or the first channel based on the second signal to send the first signal.

[0280] For the specific principle of backscattering, please refer to the description before the embodiment of FIG. 2A .

[0281] Optionally, in other embodiments, if the first device communicates based on "non-backscatter", for example, the first device actively sends a signal, the first device can actively send the first signal on the first resource and / or the first channel in the form of an autonomously generated signal, without the need to send the first signal through backscattering.

[0282] Step 2104: The second device sends a third signal.

[0283] Optionally, in some embodiments, when the second device learns that the first device has data to be sent based on the first signal sent by the first device, the second device may send a third signal to the first device. The third signal may be used by the first device to perform backscatter communication. The third signal may be, for example, the aforementioned CW signal. Furthermore, the third signal may carry at least one of the following:

[0284] Third resource;

[0285] Third channel;

[0286] Data request (data request).

[0287] Optionally, the above-mentioned third resource can be a resource scheduled from the second device to the first device for the first device to send an identification and / or data (for example, the first information described later); the above-mentioned third channel can be a channel scheduled from the second device to the first device for the first device to send an identification and / or data (for example, the first information).

[0288] Optionally, the above data request may be used to request data to be sent by the first device.

[0289] Step 2105: The first device sends first information on a third resource and / or a third channel.

[0290] Optionally, the first information may be used to indicate that the first device has data to be sent, and the first information may include at least one of the following:

[0291] a device identifier of the first device;

[0292] data to be sent by the first device;

[0293] a device type of the first device;

[0294] a first indication, the first indication being used to indicate that the first device has data to be sent;

[0295] The second indication is used to indicate the amount of data to be sent by the first device. Optionally, the second indication may be similar to a Buffer Status Report (BSR), for example.

[0296] Optionally, the device identifier of the first device may be a random number, a random sequence, a random string, or an index of the first device. In other embodiments, the device identifier may be a core network unique identifier. Exemplarily, the device identifier may include at least one of a country code, a region code, a service code, and an IoT device index. Furthermore, other possible implementations of the device identifier are not specifically limited in this disclosure.

[0297] Optionally, the device type of the above-mentioned first device can be the first type or the second type described before the embodiment of Figure 2A. And, for a detailed introduction to the "first type and the second type", please refer to the description before the embodiment of Figure 2A. Or, optionally, the device type of the above-mentioned first device can be "backscatter" and "non-backscatter", wherein "backscatter" can, for example, refer to: sending signals based on backscatter; "non-backscatter" can, for example, refer to: actively sending signals. And, the first device can indicate whether the signal generation type of the first device is "backscatter" or "non-backscatter" through the first information. It should be noted that the device type mentioned above is only an example, and there may be other forms of naming device types, which are not specifically limited in this disclosure.

[0298] Optionally, the above-mentioned first indication can be an M-bit value, where M is a positive integer, wherein when the M-bit value is a first value (such as 1), it can indicate that the first device has data to be sent; when the M-bit value is a second value (such as 0), it can indicate that the first device does not have data to be sent. Alternatively, when the M-bit value is a second value (such as 0), it can indicate that the first device has data to be sent; when the M-bit value is a first value (such as 1), it can indicate that the first device does not have data to be sent. The above-mentioned first indication is only an example, and there may be other indication methods, which are not specifically limited in this disclosure.

[0299] In some embodiments, different first devices may use different methods to send the first information. Optionally, in some embodiments, if the first device communicates based on "backscattering", the first device may perform backscattering on a third resource and / or a third channel based on a third signal to send the first information, wherein the specific principle of backscattering may refer to the description before the embodiment of FIG2A. In other embodiments, if the first device communicates based on "non-backscattering", for example, if the first device actively sends a signal, the first device may actively send the first information on a third resource and / or a third channel in the form of an autonomously generated signal without backscattering.

[0301] It should be noted that in some embodiments, when the first device has a large amount of data to be sent and cannot be sent in one go, steps 2104 and 2105 may be repeated multiple times. That is, after executing step 2105, the second device may again send a third signal, which may still carry at least one of a third resource, a third channel, and a data request, and the first device may again send the first information on the third resource and / or the third channel, and this cycle continues until the first device has sent all the data to be sent.

[0302] In the above embodiment, when the first device determines that there is data to be sent, the first device will send a first signal to indicate that the first device has data to be sent. The first device may be an Internet of Things device, and the first signal may be sent to a network device. After the network device receives the first signal, it may schedule resources for sending the data to be sent by the first device to the first device, so that the first device can successfully send the data to be sent based on the resources scheduled by the network device. It can be seen that the present disclosure provides a method for resource request of a first device, which facilitates the first device to request resources for its data to be sent, ensures the successful sending of the data to be sent by the first device, and ensures the stability of the communication of the first device.

[0305] FIG2B is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2B , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:

[0306] Step 2201: The second device sends a second signal, where the second signal carries a second resource and / or a second channel.

[0307] Optionally, the second signal may be used for backscatter communication by the first device, and the second signal may be a CW signal. Furthermore, the second resource may be a resource that the second device schedules to the first device for the first device to send an identifier and / or data (e.g., first information); and the second channel may be a channel that the second device schedules to the first device for the first device to send an identifier and / or data (e.g., first information).

[0308] For other detailed descriptions of step 2201, please refer to the above embodiment description.

[0309] Step 2202: The first device determines that there is data to be sent.

[0310] For an introduction to step 2202 , please refer to the description of the above embodiment.

[0311] Step 2203: The first device sends first information on a second resource and / or a second channel.

[0312] In some embodiments, different first devices may have different methods for sending the first information. Optionally, in some embodiments, if the first device communicates based on "backscattering", the first device may be based on the second signal to perform backscattering on the second resource and / or the second channel to send the first information, wherein the specific principle of backscattering can refer to the description before the embodiment of Figure 2A. In other embodiments, if the first device communicates based on "non-backscattering", such as the first device actively sending a signal, the first device may actively send the first information on the second resource and / or the second channel in the form of an autonomously generated signal without backscattering.

[0313] Optionally, in some embodiments, the first information may include at least one of the following:

[0320] Furthermore, as can be seen from the above step 2203, the first device can transmit the data to be sent to the first device by transmitting the first information on the second resource and / or the second channel. However, in some embodiments, when the first device has not yet completed transmitting the data to be sent by the first device in step 2203, subsequent steps may be continued.

[0321] Step 2204: The second device sends a third signal.

[0322] Optionally, the third signal may carry at least one of the following:

[0323] Third resource;

[0324] Third channel;

[0325] a device identifier of the first device;

[0326] Data request (data request).

[0327] For a detailed description of the third resource, the third channel, and the data request, reference may be made to the above embodiment. Furthermore, the "device identifier of the first device" carried in the third signal may be the device identifier of the first device determined from the first information sent by the first device in step 2203 after the second device receives the first information.

[0328] Step 2205: The first device sends first information on a third resource and / or a third channel.

[0329] For a detailed description of steps 2204-2205, please refer to the description of the aforementioned embodiment.

[0330] Furthermore, it should be noted that, in some embodiments, when the first device has not completed sending the data to be sent by the first device in step 2205, the above steps 2204 and 2205 may be repeated multiple times. That is, after executing step 2205, the second device may again send a third signal, which may still carry at least one of the third resource, the third channel, the device identifier of the first device, and the data request, and the first device may send the first information on the third resource and / or the third channel, and this cycle may continue until the first device has completed sending the data to be sent.

[0331] In the above embodiment, when the first device determines that there is data to be sent, the first device will send a first message to indicate that the first device has data to be sent. The first device may be an Internet of Things device, and the first message may be sent to a network device. After the network device receives the first message, it may schedule resources for sending the data to be sent by the first device to the first device, so that the first device can successfully send the data to be sent based on the resources scheduled by the network device. It can be seen that the present disclosure provides a method for resource request of a first device, which facilitates the first device to request resources for its data to be sent, ensures the successful sending of the data to be sent by the first device, and ensures the stability of the communication of the first device.

[0332] The communication method involved in the embodiments of the present disclosure may include at least one of steps 2201 to 2205. For example, step 2201 may be implemented as an independent embodiment, step 2202 may be implemented as an independent embodiment, and steps 2201+2202 may be implemented as independent embodiments, but are not limited thereto.

[0336] Step 2302: The energy of the first device is insufficient to support the first device to send the first information, and the first device determines a first resource and / or a first channel.

[0337] Optionally, in some embodiments, the aforementioned "insufficient energy of the first device to support the first device in transmitting the first information" may, for example, mean that the first device's power is insufficient to support the first device in carrying the first information during backscattering or active transmission. In this case, it indicates that the first device is unable to successfully transmit the first information, that is, it indicates that the first device is currently unable to transmit the data to be transmitted by the first device. The first device then needs to determine a first resource and / or a first channel so that the first device can subsequently transmit a first signal based on the first resource and / or the first channel. Optionally, the first signal may be used by the first device to request resources for transmitting the data to be transmitted.

[0338] It should be noted that the above description of "the first device's energy being insufficient to support the first device in transmitting the first information" is merely an example. Other circumstances may also cause the first device to be unable to transmit the first information, such as insufficient backscattered excitation energy or the first information being too long, and this disclosure does not specifically limit this. Furthermore, any other circumstances that cause the first device to be unable to transmit the first information are within the scope of protection of this disclosure.

[0342] Optionally, in other embodiments, if the first device communicates based on "non-backscatter", for example, the first device actively sends a signal, the first device can actively send the first signal on the first resource and / or the first channel in the form of an autonomously generated signal, without the need to send the first signal through backscattering.

[0343] Step 2304: The second device sends a third signal.

[0345] For a detailed description of steps 2301 - 2305 , please refer to the above embodiment description.

[0346] In the above embodiment, when the first device determines that there is data to be sent, the first device will send a first signal to indicate that the first device has data to be sent. The first device may be an Internet of Things device, and the first signal may be sent to a network device. After the network device receives the first signal, it may schedule resources for sending the data to be sent by the first device to the first device, so that the first device can successfully send the data to be sent based on the resources scheduled by the network device. It can be seen that the present disclosure provides a method for resource request of a first device, which facilitates the first device to request resources for its data to be sent, ensures the successful sending of the data to be sent by the first device, and ensures the stability of the communication of the first device.

[0507] Figure 5A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 5A, the embodiment of the present disclosure relates to a communication method for a communication system including a first device and a network device. The method includes at least one of the following:

[0508] Step 5101: The first device determines that there is data to be sent, and sends first information and / or a first signal.

[0510] Optional implementations of steps 5101 and 5102 may refer to the description of the above embodiments.

[0511] In some embodiments, the above method may include the method described in the above embodiments of the communication system side, terminal side, network device side, etc., which will not be repeated here.

[0512] The communication method involved in the embodiment of the present disclosure may include at least one of steps 5101 to 5102. For example, step 5101 may be implemented as an independent embodiment, and step 5102 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0513] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0514] The following is an exemplary introduction to the above method.

[0515] Optional example 1: Dedicated first resources are defined for backscattering A-IOT devices, and type A and type B A-IOT devices request resources / channels through the dedicated first resources.

[0516] Embodiment: One or more new parameters are defined to indicate a first resource configuration dedicated to an A-IOT device. The first resource configuration may include a set of resources used to request resources from a base station. This is similar to the SR resources in NR. The configuration of the first resource may be pre-configured to the A-IOT device or specified by the protocol or configured to the A-IOT device through configuration signaling issued by the base station. The specific method for obtaining the first resource configuration information is not specifically limited in this disclosure.

[0517] Embodiment: Exemplarily, two first resource configurations are defined, and dedicated first resource configurations are defined for device types AB respectively. Exemplarily, one dedicated first resource configuration is defined, and one dedicated first resource configuration is defined for device types AB.

[0518] Example: Type A and Type B A-IOT devices determine that they need to send uplink data but have no uplink resources. After receiving the excitation signal CW (continuous wave), the Type A and Type B A-IOT devices send indication information on the first resource associated with Type A / B or the device group through backscatter (for example, an energy pulse can be backscattered on the resource) to notify the base station that the Type A / B A-IOT devices have data to be sent. After receiving the indication information, the base station continues to send CW / data request. After receiving the CW / data request, the Type A and Type B A-IOT devices continue to carry the A-IOT device identification and / or device type and / or the amount of data to be transmitted (similar to BSR) and / or the data to be transmitted through backscatter in the backscatter signal. After receiving the backscatter signal, the base station continues to send a CW / data request, which carries the A-IOT device identifier. After receiving the CW / data request, the Type A and Type B A-IOT devices use the A-IOT device identifier carried in the CW / data request to determine that it is a data request service issued by the network in response to their request. Type A and Type B A-IOT devices carry the A-IOT device identifier and / or data to be transmitted through backscattering.

[0519] As another possible implementation, after receiving the excitation signal CW (continuous wave), the A-IOT devices of type A and type B carry the A-IOT device identification and / or device type and / or the amount of data to be transmitted (similar to BSR) and / or the data to be transmitted in the backscattered signal through backscattering. After receiving the CW, the base station continues to send a CW / data request, which carries the A-IOT device identification and / or UL grant. After receiving the CW / data request, the A-IOT device continues to carry the A-IOT device identification and / or the amount of data to be transmitted (similar to BSR) and / or the data to be transmitted in the backscattered signal through backscattering. In a possible implementation, the A-IOT devices of type A and type B determine that the backscattered signal is insufficient to carry the A-IOT device identification and / or device type and / or the amount of data to be transmitted (similar to BSR) and / or the data to be transmitted, and the A-IOT devices of type A and type B send indication information on the first resource associated with type A / B through backscattering.

[0520] As another possible implementation, after receiving the excitation signal CW (continuous wave), the A-IOT devices of type A and type B carry the A-IOT device identification and the indication of data to be transmitted in the backscattered signal through backscattering. Exemplarily, an indication bit is used to indicate that there is data to be transmitted. After receiving the CW, the base station continues to send a CW / data request, which carries the A-IOT device identification and / or resources. After receiving the CW / data request, the A-IOT device continues to carry the A-IOT device identification and / or the amount of data to be transmitted (similar to BSR) and / or the data to be transmitted in the backscattered signal through backscattering. In a possible implementation, the A-IOT devices of type A and type B determine that the backscattered signal is insufficient to carry the A-IOT device and the indication of data to be transmitted, and the A-IOT devices of type A and type B send the indication information on the first resource associated with type A / B through backscattering.

[0521] Example: The A-IOT device identifier can be a random number, random sequence, random string, or device index, or a core network unique identifier. Exemplarily, the device identifier can include a country code, region code, service code, and / or IoT device index. Other possible implementations are not specifically limited in this disclosure.

[0522] The present disclosure proposes an uplink resource request method in an A-IOT scenario, which solves the problem of how to support a large number of type A and type B A-IOT devices with small memory, low processing power, no battery, and small data transmission to request uplink resources in the A-IOT scenario.

In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.
