[0030] The technical solution in this application will be described below with reference to the accompanying drawings.

[0031] Ambient Internet of Things (A-IoT)

[0032] A-IoT communication utilizes energy harvesting and backscatter communication technologies. A-IoT devices are IoT devices that use various environmental energies, such as radio frequency energy, light energy, solar energy, thermal energy, and mechanical energy, to power themselves. These devices can have no energy storage capacity or very limited energy storage capacity (e.g., using capacitors with a capacity of tens of microfarads). Compared to traditional Internet of Things (IoT) devices, A-IoT devices offer numerous advantages, including the absence of conventional batteries, maintenance-free operation, compact size, reduced complexity, low cost, and a long lifespan.

[0033] The AIoT can include a network device 110 and an A-IoT device 120, as shown in Figure 1. The network device is used to send wireless power supply signals and downlink communication signals to the A-IoT device and to receive backscattered signals from the A-IoT device. A basic A-IoT device includes an energy harvesting module, a backscatter communication module, and a low-power computing module. Furthermore, the A-IoT device may also include a memory or sensor for storing basic information (such as item identification) or acquiring sensor data such as ambient temperature and humidity.

[0034] It should be noted that Figure 1 exemplarily shows a network device and an A-IoT device. Optionally, the communication system 100 may include multiple network devices and each network device may include another number of A-IoT devices within its coverage area. This embodiment of the present application does not limit this.

[0035] In addition, in some implementations, the communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiments of the present application.

[0036] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: fifth generation (5G) system or new radio (NR), long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), cellular Internet of Things, etc. The technical solutions provided in this application can also be applied to future communication systems, such as the sixth generation mobile communication system, etc.

[0037] The A-IoT device in the embodiment of the present application can be used as a terminal device, which can also be called user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), mobile terminal (MT), remote station, remote terminal, mobile device, user terminal, terminal device, wireless communication device, user agent or user device. The terminal device in the embodiment of the present application can be a device that provides voice and / or data connectivity to the user, which can be used to connect people, objects and machines, such as household appliances, sensors, electronic tags, etc. with wireless connection functions. The terminal in the embodiment of the present application can be a wireless terminal in a smart home, a wireless terminal in an IWSN, a wireless terminal in smart logistics and smart warehousing, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, etc.

[0038] The network device in the embodiment of the present application may be a device for communicating with a terminal device. If the terminal is an electronic tag, the network device may be a reader / writer for reading and writing the electronic tag (for example, a reader / writer based on radio frequency identification (RFID) technology). The network device may also be an access network device or a wireless access network device, such as a base station. The network device in the embodiment of the present application may refer to a radio access network (RAN) node (or device) that connects the terminal device to a wireless network. A base station can broadly cover various names as follows, or be replaced with the following names, such as: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmission point (TRP), transmission point (TP), master station MeNB, secondary station SeNB, multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station can be a macro base station, a micro base station, a relay node, a donor node or the like, or a combination thereof. A base station can also refer to a communication module, a modem or a chip used to be set in the aforementioned device or apparatus. The base station can also be a mobile switching center and a device that performs base station functions in device-to-device D2D, vehicle-to-everything (V2X), and machine-to-machine (M2M) communications, a network-side device in a 6G network, or a device that performs base station functions in future communication systems. The base station can support networks with the same or different access technologies. The embodiments of this application do not limit the specific technology and specific device form used by the network equipment.

[0039] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move based on the location of the mobile base station. In other examples, a helicopter or drone can be configured to act as a device that communicates with another base station.

[0040] In some deployments, the network device in the embodiments of the present application may refer to a CU or a DU, or the network device may include a CU and a DU. The gNB may also include an AAU.

[0041] The network equipment and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; they can also be deployed in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the scenarios in which the network equipment and terminal devices are located.

[0042] It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0043] In some implementations, the terminal 120 may include an energy collection module 121 and a backscatter communication module 122. The energy collection module 121 and the backscatter communication module 122 will be introduced below in conjunction with Figures 2 to 4. For the sake of brevity, they will not be repeated here. In some cases, the terminal 120 may also include a low-power computing module 123. The low-power computing module 123 is used to provide computing functions for the terminal, such as data processing. In other cases, the terminal 120 may also include a sensor 124 for collecting external information (for example, ambient temperature, ambient humidity, etc.). In other cases, the terminal 120 may also include a memory 125 for storing some information (for example, external information collected by the above-mentioned sensors, or such as item identification, etc.).

[0044] The energy harvesting module 121 is used to harvest energy. In some implementations, energy can be harvested via a wireless power supply signal transmitted by a network device. The wireless power supply signal can be a "radio frequency signal" transmitted by the network device. Therefore, the energy harvesting module is also referred to as a "radio frequency energy harvesting module."

[0045] FIG2 shows a possible structure of an energy collection module. As shown in FIG2 , the energy collection module 121 can collect the energy of the spatial electromagnetic waves of the radio frequency signal based on the principle of electromagnetic induction, and store the collected energy in the capacitor C, which is the charging process of the capacitor C. When the charging process of the capacitor C is completed, the capacitor C can start to discharge to provide energy for the terminal operation. For example, the discharge of the capacitor C can be used to drive the terminal to perform low-power demodulation of the data sent by the network device. For another example, the discharge of the capacitor C can be used to drive the terminal to modulate the data to be sent. For another example, the discharge of the capacitor C can be used to drive the sensor of the terminal to collect data. For another example, the discharge of the capacitor C can be used to drive the terminal to read the data in the memory 125, etc.

[0046] The backscatter communication module 122 is used for backscattering communication between the terminal and the network device. The principle of backscattering communication in an embodiment of the present application is described below in conjunction with FIG3 . Referring to FIG3 , the terminal 120 receives a wireless signal transmitted by the network device 110 and modulates the wireless signal to carry the information to be transmitted. Finally, the modulated signal is radiated from the antenna. This information transmission process is called backscattering communication. Backscattering communication and load modulation are closely related. Load modulation adjusts and controls the circuit parameters of the terminal's oscillating circuit according to the data stream's rhythm, causing parameters such as the terminal impedance to change accordingly, thereby completing the modulation process. Load modulation techniques mainly include resistive load modulation and capacitive load modulation. In resistive load modulation, a resistor is connected in parallel to the load, and the resistor is turned on or off based on the control of the binary data stream, as shown in FIG4 below. The switching of the resistor causes a change in the circuit voltage, thereby implementing amplitude-shift keying (ASK) modulation, which modulates and transmits the signal by adjusting the amplitude of the terminal's backscattered signal. Similarly, in capacitive load modulation, the resonant frequency of the circuit can be changed by switching the capacitor on and off, realizing frequency-shift keying (FSK) modulation, that is, signal modulation and transmission are achieved by adjusting the operating frequency of the terminal's backscattered signal.

[0047] In some implementations, the transmit (transmit, TX) path of the network device 110 may be further provided with other devices for processing the transmitted signal, such as an amplifier (AMP). The receive (receive, RX) path of the network device 110 may also be provided with other devices for processing the received signal, such as a low noise amplifier (LNA).

[0048] In other implementations, the terminal 120 may be provided with an energy collection unit for collecting energy from the wireless power supply signal sent by the network device. Of course, the terminal 120 may also be provided with a logic processing unit to perform corresponding calculation functions.

[0049] It should be noted that, whether it is the network device 110 or the terminal 120, Figure 3 only shows the connection structure of the signal processing circuit as an example. The processing circuit of the network device 110 and / or the terminal 120 may include other components, and the embodiments of the present application do not specifically limit this.

[0050] Typically, load modulation can be achieved through resistive load modulation and capacitive load modulation. Figure 4 shows a circuit diagram of a terminal based on resistive load modulation technology. It should be noted that the circuit shown in Figure 4 implements load modulation technology in a manner similar to existing circuits implementing load modulation technology. For the sake of simplicity, the functions of resistors R2 and R3, capacitors C1 and C2, and inductors L1 and L2 shown in Figure 4 are not further described.

[0051] In resistive load modulation, a resistor R can be connected in parallel with the load. L The switch S can be controlled based on the binary data flow to realize the resistor R L In this way, the resistor R L The on-off of the switch will cause the circuit voltage to change, and the change of the circuit voltage can control the amplitude of the backscattered signal of the terminal, thereby realizing the modulation of the backscattered signal, that is, ASK modulation of the backscattered signal.

[0052] Similarly, in capacitive load modulation, the on-off switching of the capacitor can be controlled based on a binary data stream to change the circuit resonant frequency, thereby changing the operating frequency of the backscattered signal to achieve FSK modulation.

[0053] As mentioned above, terminals can use load modulation to modulate incoming signals (i.e., signals sent by network devices) to achieve backscatter communication. Therefore, terminals in backscatter communication generally have the following advantages.

[0054] Advantage 1: Since the terminal does not need to actively transmit signals, there is no need to construct a complex RF path. For example, components such as power amplifiers (PAs) and RF filters can be omitted in the RF path, reducing the cost and size of the terminal.

[0055] The second advantage is that since the terminal does not need to actively generate high-frequency signals, a high-frequency crystal oscillator is not required, thereby reducing the cost and size of the terminal.

[0056] Advantage three: Since the terminal can use backscatter technology to communicate with network equipment, the terminal consumes less energy during communication and does not even need to consume its own energy.

[0057] Classification of A-IoT devices

[0058] In some scenarios, A-IoT devices can be divided into three categories based on their energy sources and energy usage: passive A-IoT devices, semi-passive A-IoT devices, and active A-IoT devices.

[0059] 1. Passive A-IoT devices

[0060] Passive A-IoT devices generally do not require built-in batteries. When an A-IoT device is close to a network device, the A-IoT device is within the near field formed by the radiation of the network device's antenna. At this time, the antenna of the A-IoT device can generate an induced current through electromagnetic induction. The induced current can power the A-IoT device to achieve demodulation of the received signal and / or modulation and encoding of the transmitted signal. In some implementations, the above-mentioned passive A-IoT device can be an electronic tag, and accordingly, the network device can be a reader / writer of a (radio frequency identification, RFID) system, which is used to read the content in the electronic tag and / or to change the content in the electronic tag.

[0061] 2. Semi-passive A-IoT devices

[0062] Semi-passive A-IoT devices don't have conventional batteries themselves, but instead use an energy harvesting module 121 to harvest radio wave energy and store it in an energy storage unit (e.g., a capacitor). This energy storage unit then powers the A-IoT device to demodulate received signals and / or modulate and encode transmitted signals.

[0063] Active A-IoT devices

[0064] Active A-IoT devices can have built-in batteries. These batteries power the A-IoT device to demodulate received signals and / or modulate and encode transmitted signals. However, when the A-IoT device communicates using backscatter technology, it does not consume battery power. Therefore, for such A-IoT devices, "zero power consumption" is primarily achieved when the terminal uses backscatter technology for communication.

[0065] In some implementations, the active A-IoT device can be an electronic tag, and the network device can be an RFID reader. In this case, the internal battery can power the RFID chip in the A-IoT device, increasing the read / write distance between the RFID reader and the electronic tag. Furthermore, the internal battery can power the RFID chip in the A-IoT device, shortening the latency between the RFID reader and the electronic tag, thereby improving communication reliability.

[0066] In other scenarios, A-IoT devices can be divided into three categories based on transmitter type, including the following types: A-IoT devices based on backscattering, A-IoT devices based on active transmitters, and A-IoT devices with both backscattering and active transmitters.

[0067] 1) Backscatter-based A-IoT devices.

[0068] These A-IoT devices use the aforementioned backscattering method to transmit uplink data. These devices lack active transmitters, only backscattering transmitters. Therefore, when these devices transmit data, they require network equipment to provide a carrier, which they then use to perform backscattering to achieve data transmission.

[0069] 2) A-IoT devices based on active transmitters.

[0070] These A-IoT devices use active transmitters with active transmission capabilities for uplink data transmission. Therefore, when sending data, these A-IoT devices can use their own active transmitters to send data without the need for network equipment to provide a carrier. Examples of active transmitters suitable for A-IoT devices include ultra-low-power ASK and FSK transmitters. Based on current implementations, these transmitters can reduce overall power consumption to 400-600uW when transmitting a 100uW signal.

[0071] 3) A-IoT devices with both backscatter and active transmitters.

[0072] This type of terminal supports both backscatter and active transmitters. The terminal can determine which uplink signal transmission method to use: backscatter or active transmitter, based on various conditions (such as battery life and available ambient energy) or based on network device scheduling.

[0073] Low-power IoT based on cellular networks

[0074] The cellular Internet of Things (IoT) is booming. 3GPP has standardized IoT technologies such as narrowband IoT (NB-IoT), machine-type communication (MTC), and reduced capability (RedCap). However, there are still many scenarios where IoT communication needs cannot be met using existing technologies. These include harsh communication environments (high temperature, low temperature, high humidity, high voltage, high radiation, or high-speed movement), the need for extremely small terminal form factors, and extremely low costs.

[0075] Therefore, in order to cover these unmet IoT communication needs, cellular networks also need to develop ultra-low-cost, extremely small-size, battery-free / maintenance-free IoT, and environmental IoT can just meet this need.

[0076] Based on the discussion of A-IoT application scenarios in 3GPP system architecture (SA)1, A-IoT can be used in at least the following four scenarios:

[0077] Object recognition, such as logistics, production line product management, and supply chain management.

[0078] Environmental monitoring, such as temperature, humidity, and harmful gas monitoring of the working environment and natural environment.

[0079] Positioning, such as indoor positioning, intelligent object search, and production line item positioning.

[0080] Intelligent control, such as intelligent control of various electrical appliances in smart homes (turning on and off air conditioners, adjusting temperature), and intelligent control of various facilities in agricultural greenhouses (automatic irrigation and fertilization).

[0081] In a low-power IoT based on a cellular network, an A-IoT device can directly transmit and receive carriers, data, or signals from a base station, and send or backscatter data or channels to the base station, as shown in Figure 5 (represented as the first topology). Alternatively, communication between the A-IoT and the base station can be achieved through an intermediate node. In this case, the intermediate node sends carriers, data, or signals to the A-IoT device, and the A-IoT device sends or backscatters data or signals to the intermediate node (Intermediate Node), as shown in Figure 6 (represented as the second topology).

[0082] In some scenarios, the control information sent by the network device to the intermediate node can be called downlink control information (DCI). The data channel sent by the network device to the intermediate node can be recorded as a physical downlink shared channel (PDSCH). The control information sent by the intermediate node to the A-IoT device can be recorded as A-IoT control information (A-DCI or ACI). The data channel sent by the intermediate node to the A-IoT device can be recorded as the A-IoT physical downlink data channel (A-PDSCH). The data channel sent by the A-IoT device to the intermediate node can be recorded as the A-IoT physical uplink shared channel (A-PUSCH).

[0083] 3GPP Cellular Ambient IoT Discussion Progress

[0084] Cellular Internet of Things is booming. 3GPP has standardized IoT technologies such as NB-IoT, MTC, and RedCap. However, there are still many scenarios where IoT communication needs cannot be met using existing technologies.

[0085] For example, consider harsh communication environments. Certain IoT scenarios may face extreme conditions such as high temperatures, extremely low temperatures, high humidity, high voltage, high radiation, or high-speed movement. Examples include ultra-high voltage substations, high-speed train track monitoring, environmental monitoring in high-altitude cold regions, and industrial production lines. In these scenarios, existing IoT terminals will not function due to the operating environment limitations of conventional power supplies. Furthermore, extreme operating environments are also detrimental to IoT maintenance, such as battery replacement.

[0086] Another example is the demand for extremely small terminal form factors. Certain IoT communication scenarios, such as food traceability, commodity distribution, and smart wearables, require terminals to be extremely small for ease of use. For example, IoT terminals used for commodity management in the distribution process often take the form of electronic tags, embedded in product packaging in a very compact form factor. Another example is lightweight wearable devices that can meet user needs while improving the user experience.

[0087] Another example is the demand for extremely low-cost IoT communications. Numerous IoT communication scenarios require IoT terminals to be sufficiently inexpensive to enhance their competitiveness compared to alternative technologies. For example, in logistics or warehousing scenarios, to facilitate the management of large numbers of circulating items, IoT terminals can be attached to each item. Communication between the terminal and the logistics network enables precise management of the entire logistics process and lifecycle. These scenarios require IoT terminals to be competitively priced.

[0088] Therefore, in order to cover these unmet IoT communication needs, cellular networks also need to develop ultra-low-cost, extremely small-size, battery-free / maintenance-free IoT, and zero-power IoT can just meet this need.

[0089] During standardization discussions, the term "zero-power IoT" has been coined as "Ambient Power Enabled IoT," or "Ambient IoT" for short. In some technical literature, it's also referred to as "passive IoT." An ambient IoT device is one that uses various environmental energies, such as radio frequency energy, light, solar energy, thermal energy, and mechanical energy, to power itself. Such a device can have no energy storage capacity or very limited energy storage capacity (such as using capacitors with a capacity of tens of microfarads). Compared to existing IoT devices, ambient IoT devices offer numerous advantages, including the absence of conventional batteries, maintenance-free operation, compact size, low complexity, low cost, and a long lifespan.

[0090] In some discussions (e.g., 3GPP RAN#102 plenary discussion), the SID for the A-IoT physical layer was adopted, which includes at least the following two A-IoT device types:

[0091] Category 1 A-IoT devices: A-IoT devices with a peak power consumption of ~1uW. These A-IoT devices have energy storage, an initial sampling frequency offset of 10X ppm, no uplink or downlink power amplifiers, and send uplink transmissions by backscattering an external carrier.

[0092] Category 2 A-IoT devices: A-IoT devices have a peak power consumption of ≤ a few hundred μW (a few hundred μW peak power consumption1), which is less than a few hundred uW. The A-IoT device has energy storage and an initial sampling frequency offset of 10X ppm. It may be configured with uplink and / or downlink power amplifiers and can generate uplink transmissions internally in the A-IoT device, i.e., active transmissions, or send uplink transmissions by backscattering an external carrier.

[0093] A-IoT mainly considers the following two deployment scenarios / topologies, which are introduced below with reference to Figures 5 and 6.

[0094] See Figure 5, deployment scenario 1 using topology: BS A-IoT devices, base stations and A-IoT devices directly conduct two-way signaling and / or data communication. The base station sending to the A-IoT device and the base station receiving the A-IoT device may be two different base stations.

[0095] See Figure 6, deployment scenario 2 using topology: BS intermediate node A-IoT devices communicate bidirectionally with intermediate nodes, which relay signaling and / or data between the base station and the A-IoT device. During the SID discussion phase, the intermediate node was ultimately determined to be a UE under network control and located indoors.

[0096] Next, we'll use the example shown in Figure 6 to illustrate deployment scenario 2. Assume the intermediate node is a mobile phone and the A-IoT device is a tag. The existing uplink and downlink communications are used between the phone and the base station, while the ambient energy IoT communication is used between the phone and the tag. For A-IoT DL, the phone's transmission requires a simple waveform and encoding scheme, enabling the tag to demodulate A-IoT DL data with ultra-low power consumption after acquiring RF or ambient energy. For A-IoT UL, if the tag in Figure 6 uses backscatter transmission, another node must provide the tag with a carrier. After acquiring RF or ambient energy, the tag drives the circuit to modulate the carrier, thereby transmitting the A-IoT UL signal via backscatter. However, if the tag in Figure 6 uses active transmission, no carrier is required. The tag generates and modulates the carrier after acquiring RF or ambient energy, completing the A-IoT UL transmission.

[0097] Combining deployment scenario 2 in Figure 6 with the smart home scenario further illustrates:

[0098] Case 1: Assume that the base station receives a command to turn on the air conditioner from the cloud or core network and sends it to a mobile phone indoors via UU DL. The mobile phone then sends the command to a tag integrated with the air conditioner via A-IoT DL. If the tag receives the command and turns on the air conditioner, it can send a feedback message to the mobile phone via A-IoT UL to confirm that the air conditioner has turned on. The mobile phone then sends feedback to the base station via UU UL.

[0099] Case 2: Assume the base station receives a home command from the cloud or core network and sends it to a mobile phone indoors via UU DL. Based on the home command, the mobile phone then sends a series of commands to tags integrated into various devices via A-IoT DL, such as turning on the air conditioner, opening the curtains, and turning on the air purifier. After any tag receives the power-on command and performs the corresponding operation, it sends feedback to the phone via A-IoT UL, confirming that the corresponding device has been turned on. The phone then evaluates whether the home command has been fulfilled (for example, whether all corresponding devices are turned on) and further reports back to the base station via UU UL.

[0100] Note: The difference between Case 1 and Case 2 is that in Case 1, the intermediate node directly forwards the network command, while in Case 2, it converts the home command into a series of other commands and sends them down. In addition, in Case 2, one intermediate node can correspond to one A-IoT device or multiple A-IoT devices.

[0101] In some scenarios, feedback information between communicating devices needs to be forwarded through an intermediate node, and how to forward this feedback information remains an unresolved issue. For example, in the ambient IoT, communication between a network device and a second device (e.g., an A-IoT device) is based on the first device. However, there is currently no specification for how the first device generates feedback information to be reported to the network device based on feedback information sent to it by the second device.

[0102] Therefore, to address the above issues, embodiments of the present application propose a wireless communication method that specifies a method for transmitting feedback information in a scenario where communication is conducted by a first device. This method helps unify the understanding of feedback between communication devices and increases the likelihood of successful communication. The wireless communication method according to embodiments of the present application is described below with reference to FIG7 . The method shown in FIG7 includes step S710.

[0103] In step S710 , the first device determines second feedback information based on the first feedback information.

[0104] In some implementations, the first feedback information is used for communication between the second device and the first device. For example, the first feedback information is used by the second device to provide feedback to the first device.

[0105] In some implementations, the first feedback information includes a positive acknowledgement and / or a negative acknowledgement, wherein the positive acknowledgement may be, for example, ACK, and the negative acknowledgement may be, for example, NACK.

[0106] In the embodiment of the present application, the manner in which the second device sends the first feedback information is not limited. In some implementations, the first feedback information may be sent by the second device via backscattering, or the first feedback information may be sent by the second device via active transmission.

[0107] In the embodiments of the present application, the feedback method of the first feedback information is not limited. In some implementations, the feedback method corresponding to the first feedback information is to send only an affirmative acknowledgement (also known as "ACK-ONLY"). For example, when the second device successfully receives or successfully executes the command sent by the first device, the first feedback information sent by the second device to the first device can be a positive acknowledgement. Conversely, when the second device fails to successfully receive or successfully execute the command sent by the first device, the second device does not send the first feedback information.

[0108] In some implementations, the feedback mode corresponding to the first feedback information is to send only a negative acknowledgement (also known as "NACK-ONLY"). For example, when the second device fails to successfully receive or execute a command sent by the first device, the second device may send the first feedback information to the first device as a negative acknowledgement. Conversely, when the second device successfully receives or executes the command sent by the first device, the second device does not send the first feedback information.

[0109] In some implementations, the feedback mode corresponding to the first feedback information is to send both a positive acknowledgement and a negative acknowledgement, wherein the feedback mode of sending both a positive acknowledgement and a negative acknowledgement can be understood as sending a negative acknowledgement for a negative acknowledgement scenario, and sending a positive acknowledgement for a positive acknowledgement scenario, rather than only sending a positive acknowledgement or only sending a negative acknowledgement as described above.

[0110] Exemplarily, when the second device successfully receives or successfully executes the command sent by the first device, the first feedback information sent by the second device to the first device may be a positive response. Conversely, when the second device fails to successfully receive or successfully execute the command sent by the first device, the first feedback information sent by the second device to the first device may be a negative response.

[0111] In the embodiments of the present application, the method for determining the feedback method of the first feedback information is not limited. In some embodiments, the feedback method corresponding to the first feedback information can be determined based on one or more of the following methods: network device configuration; pre-configuration; protocol pre-definition; indication by the first device to the second device; the type of the second device, where the type of the second device may include: a first type A-IoT device and / or a second type A-IoT device; the method by which the second device sends the first feedback information, where the method by which the second device sends the first feedback information may include backscattering and / or active transmission.

[0112] Taking the example of a first device indicating a feedback method for first feedback information to a second device, the first device sends control information to the second device, and the indication field of the control information is used to indicate the feedback method for the first feedback information. Of course, in the embodiment of the present application, the indication field can also be used to instruct the second device not to send the first feedback information.

[0113] Taking the example of determining the feedback mode based on the method by which the second device sends the first feedback information, if the second device sends the first feedback information via backscatter, the feedback mode for the first feedback information is to send only a positive acknowledgement or only a negative acknowledgement. If the second device sends the first feedback information via active transmission, the feedback mode for the first feedback information is to send both a positive acknowledgement and a negative acknowledgement.

[0114] Taking the example of determining the feedback mode based on the type of the second device, if the second device is a first-category second device, the feedback mode for the first feedback information is to send only positive acknowledgments or only negative acknowledgments. If the second device is a second-category second device, the feedback mode for the first feedback information is to send only positive acknowledgments or only negative acknowledgments.

[0115] In some implementations, the first feedback information is physical layer signaling or higher layer signaling.

[0116] In some implementations, the first feedback information may be carried on one or more of the following: PUCCH resources; PUSCH resources; RACH resources.

[0117] In the embodiments of the present application, the modulation method of the first feedback information is not limited. In some implementations, the first feedback information may include on-off keying (OOK) modulation, amplitude shift keying (ASK) modulation, frequency shift keying (FSK) modulation, or phase shift keying (PSK) modulation.

[0118] In some other implementations, the second feedback information is used for communication between the first device and the network device. For example, the second feedback information is used for the first device to provide feedback to the network device.

[0119] In some implementations, the second feedback information includes a positive acknowledgement and / or a negative acknowledgement, wherein the positive acknowledgement may be, for example, ACK, and the negative acknowledgement may be, for example, NACK.

[0120] In the embodiments of the present application, the feedback method of the second feedback information is not limited. In some implementations, the feedback method corresponding to the second feedback information is to send only an affirmative acknowledgement (also known as "ACK-ONLY"). For example, when the command sent by the network device is successfully received or successfully executed, the second feedback information sent by the first device to the network device can be a positive acknowledgement. Conversely, when the command sent by the network device is not successfully received or successfully executed, the first device does not send the second feedback information.

[0121] In some implementations, the feedback mode corresponding to the second feedback information is to send only a negative acknowledgment (also known as "NACK-ONLY"). For example, when the command sent by the network device is not successfully received or successfully executed, the first device may send the second feedback information to the network device as a negative acknowledgment. Conversely, when the command sent by the network device is successfully received or successfully executed, the first device does not send the second feedback information.

[0122] In some implementations, the feedback mode corresponding to the second feedback information is sending both a positive acknowledgement and a negative acknowledgement. For example, when the command sent by the network device is successfully received or successfully executed, the second feedback information sent by the first device to the network device is a positive acknowledgement. Conversely, when the command sent by the network device is not successfully received or successfully executed, the second feedback information sent by the first device to the network device is a negative acknowledgement.

[0123] In the embodiment of the present application, the method for determining the feedback mode of the second feedback information is not limited. In some embodiments, the feedback mode corresponding to the second feedback information can be determined based on one or more of the following methods: network device configuration; network device indication; pre-configuration; protocol pre-definition.

[0124] In some implementations, the second feedback information is physical layer signaling or higher layer signaling.

[0125] In some implementations, the second feedback information may be carried on one or more of the following: PUCCH resources; PUSCH resources; RACH resources.

[0126] In the embodiments of the present application, the modulation method of the second feedback information is not limited. In some implementations, the second feedback information may include OOK modulation; FSK modulation; PSK modulation; quadrature phase shift keying (QPSK); 16-quadrature amplitude modulation (QAM), 64QAM, and 256QAM. In other implementations, the second feedback information is transmitted based on an orthogonal frequency division multiplexing (OFDM) waveform.

[0127] In some scenarios, the first feedback information may be feedback information for a second command, wherein the second command is sent by the first device to the second device. The second command may be determined based on the first command sent by the network device to the first device.

[0128] In the embodiments of the present application, the first command and the second command are not limited. For example, the first command and the second command may be the same command. In this case, it can be understood that the intermediate node forwards the first command sent by the network device to the A-IoT device. For another example, the first command and the second command may be different commands, and the second command is obtained after processing the first command. In this case, it can be understood that the intermediate node processes the first command sent by the network device, obtains the second command, and forwards it to the A-IoT device.

[0129] In the embodiments of the present application, the processing method of the first command is not limited. For example, the processing method may include converting the format of the first command into a command format supported by the second device. For another example, the processing method may include decapsulating the first command to obtain the second command.

[0130] As described above, the second feedback information is determined based on the first feedback information. The following describes a solution for determining the second feedback information based on the first feedback information in an embodiment of the present application.

[0131] In solution 1, if the feedback mode of the first feedback information is to only feedback a positive acknowledgement, and the first device receives the first feedback information as a positive acknowledgement, then the second feedback information is a positive acknowledgement; and / or if the feedback mode of the first feedback information is to only feedback a positive acknowledgement, and the first device does not receive the first feedback information, then the second feedback information is a negative acknowledgement.

[0132] The solution of the embodiment of the present application can be applicable to a scenario in which a second device communicates with a first device, such as a scenario in which AIOT DL is unicast.

[0133] In solution 2, if the feedback mode of the first feedback information is to only feedback a negative response, and the first device receives the first feedback information as a negative response, then the second feedback information is a negative response; and / or if the feedback mode of the first feedback information is to only feedback a negative response, and the first device does not receive the first feedback information, then the second feedback information is a positive response.

[0134] The solution of the embodiment of the present application can be applicable to a scenario in which a second device communicates with a first device, such as a scenario in which AIOT DL is unicast.

[0135] In scheme 3, if the feedback mode of the first feedback information is both a negative response and a positive response, the second feedback information satisfies one or more of the following: if the first feedback information is a negative response, the second feedback information is a negative response; if the first feedback information is a positive response, the second feedback information is a positive response; if the first device does not receive the first feedback information, the second feedback information is a negative response.

[0136] The solution of the embodiment of the present application can be applicable to a scenario in which a second device communicates with a first device, such as a scenario in which AIOT DL is unicast.

[0137] For ease of understanding, the following describes the method for sending the first feedback information and the second feedback information in an embodiment of the present application in conjunction with Figure 8. Assume that the first device is an intermediate node, the second device is an A-IoT device, and one intermediate node corresponds to one AIOT device, or in other words, one intermediate node provides services for one AIOT device. As shown in Figure 8, the network device sends a first command to the intermediate node, and the intermediate node sends a second command to the A-IoT device.

[0138] For Solution 1 above, assume that the first feedback information is sent as an affirmative response only. If the A-IoT device successfully receives or executes the second command, the first feedback information sent by the A-IoT device to the intermediate node is an affirmative response. If the A-IoT device fails to receive or execute the second command, the A-IoT device does not send the first feedback information.

[0139] Accordingly, if the first feedback information received by the intermediate node is a positive response, the second feedback information sent by the intermediate node to the network device is a positive response. If the intermediate node does not receive the first feedback information, the second feedback information sent by the intermediate node to the network device is a negative response.

[0140] For Solution 2 above, assume that the first feedback information is fed back as a negative acknowledgment only. If the A-IoT device fails to successfully receive or execute the second command, the first feedback information sent by the A-IoT device to the intermediate node is a negative acknowledgment. If the A-IoT device successfully receives or executes the second command, the A-IoT device does not send the first feedback information.

[0141] Accordingly, if the first feedback information received by the intermediate node is a negative acknowledgement, the second feedback information sent by the intermediate node to the network device is a negative acknowledgement. If the intermediate node does not receive the first feedback information, the second feedback information sent by the intermediate node to the network device is a positive acknowledgement.

[0142] For Solution 3 above, assume that the first feedback information is fed back in both a negative acknowledgment and a positive acknowledgment. If the A-IoT device successfully receives or executes the second command, the first feedback information sent by the A-IoT device to the intermediate node is a positive acknowledgment. If the A-IoT device fails to receive or execute the second command, the first feedback information sent by the A-IoT device to the intermediate node is a negative acknowledgment.

[0143] Accordingly, if the first feedback information received by the intermediate node is a positive response, the second feedback information sent by the intermediate node to the network device is a positive response. If the first feedback information received by the intermediate node is a negative response or the intermediate node does not receive the first feedback information, the second feedback information sent by the intermediate node to the network device is a negative response.

[0144] In some scenarios, the first device may communicate with multiple second devices. In this case, the first feedback information includes multiple pieces of feedback information sent by the multiple second devices. Accordingly, the second feedback information may be determined based on the multiple pieces of feedback information.

[0145] For example, a command sent by a network device may need to be sent by a first device to multiple second devices for execution. In this case, the multiple second devices will respectively send first feedback information to the first device, that is, multiple feedback information. In this case, the second feedback information can be determined based on the multiple feedback information.

[0146] In some implementations, the second feedback information is determined based on one or more of the following: the number of positive acknowledgements in the plurality of feedback information; the number of negative acknowledgements in the plurality of feedback information; and the received power of the negative acknowledgements in the plurality of feedback information.

[0147] In some implementations, the number of positive responses in the multiple feedback information may include the number of positive responses in the multiple feedback information, or the proportion of positive responses in the multiple feedback information.

[0148] In some implementations, the number of negative acknowledgments in the multiple feedback information may include the number of negative acknowledgments in the multiple feedback information, or the proportion of negative acknowledgments in the multiple feedback information.

[0149] In some implementations, if multiple feedback information meets one or more of the following conditions, the second feedback information is a positive response: the multiple feedback information does not contain a negative response; the number of positive responses in the multiple feedback information is greater than or equal to a first threshold; the proportion of positive responses in the multiple feedback information is greater than or equal to a second threshold; the number of negative responses in the multiple feedback information is less than or equal to a third threshold; the proportion of negative responses in the multiple feedback information is less than or equal to a fourth threshold; the receiving power of negative responses in the multiple feedback information is less than or equal to a fifth threshold; based on the multiple feedback information, it is determined that the first command associated with the multiple feedback information is achieved, and the first command is a command sent by the network device to the first device.

[0150] In some implementations, the command sent by the first device to the second device is a second command, where the second command may be determined based on the first command. For example, the first command may be the same as the second command. In another example, the second command may be obtained by processing the first command. In some implementations, the first feedback information may be understood as feedback regarding the execution of the second command.

[0151] In an embodiment of the present application, one or more thresholds among the first to fifth thresholds can be determined based on predefined information, preconfigured information, configuration information of the network device, etc.

[0152] In some implementations, if multiple feedback information meets one or more of the following conditions, the second feedback information includes a negative acknowledgement and / or identification information of the second device: the number of positive acknowledgements in the multiple feedback information is less than or equal to a sixth threshold; the proportion of positive acknowledgements in the multiple feedback information is less than or equal to a seventh threshold; the number of negative acknowledgements contained in the multiple feedback information is greater than or equal to an eighth threshold; the proportion of negative acknowledgements in the multiple feedback information is greater than or equal to a ninth threshold; the receiving power of negative acknowledgements in the multiple feedback information is greater than or equal to a tenth threshold; and it is determined based on the multiple feedback information that the first command associated with the multiple feedback information is not achieved, and the first command is a command sent by the network device to the first device.

[0153] In some implementations, the identification information of the second device may be understood as identification information of the second device associated with multiple pieces of feedback information. In other words, the identification information of the second device may be identification information of the second device associated with multiple second commands.

[0154] In some implementations, the identification information includes one or more of the following: an identification of a second device that sends a positive response in multiple feedback information; an identification of a second device that sends a negative response in multiple feedback information; an identification of a second device that does not receive a positive response from the first device in multiple second devices; and an identification of a second device that does not receive a negative response from the first device in multiple second devices.

[0155] In an embodiment of the present application, one or more of the sixth to tenth thresholds may be determined based on predefined information, preconfigured information, configuration information of a network device, or the like.

[0156] In some implementations, multiple pieces of feedback information occupy the same transmission resource, or multiple pieces of feedback information occupy different transmission resources.

[0157] Taking the example of multiple pieces of feedback information occupying different transmission resources, in some implementations, the multiple pieces of feedback information can be sent using TDM, or in other words, multiple second devices send the multiple pieces of feedback information using TDM. In other implementations, the multiple pieces of feedback information can be sent using FDM, or in other words, multiple second devices send the multiple pieces of feedback information using FDM. In still other implementations, the multiple pieces of feedback information can be sent using CDM, or in other words, multiple second devices send the multiple pieces of feedback information using CDM.

[0158] Taking multiple feedback information occupying the same transmission resource as an example, in some implementations, the multiple feedback information can be sent on the same time-frequency resource. In other implementations, the multiple feedback information can be sent on the same code domain resource.

[0159] For ease of understanding, the first feedback information and the second feedback information in the embodiments of the present application are introduced below with reference to Examples 1 to 5.

[0160] Example 1: Assuming that the feedback mode corresponding to the first feedback information is to only feedback positive acknowledgments, if the number X of positive acknowledgments in the first feedback information received by the first device is greater than (or equal to, or greater than or equal to) threshold 1, then the second feedback information is a positive acknowledgment. If the number X of positive acknowledgments in the first feedback information received by the first device is less than (or equal to, or less than or equal to) threshold 2, then the second feedback information includes one or more of the following: a negative acknowledgment; the second device identifier corresponding to the positive acknowledgment in the first feedback information; or the second device identifier corresponding to the second device for which no positive acknowledgment was received.

[0161] In some implementations, threshold 1 may be the same as or different from threshold 2. Threshold 1 and / or threshold 2 are configured or pre-configured by the network or predefined by a standard or depend on the implementation of the first device.

[0162] The embodiments of the present application are applicable to a scenario in which a first device provides services for multiple second devices, and the multiple second devices send first feedback information on multiple independent resources.

[0163] Example 2: Assuming that the feedback mode corresponding to the first feedback information is to only feedback positive acknowledgments, if the ratio X / Y of positive acknowledgments in the first feedback information received by the first device is greater than (or equal to, or greater than or equal to) threshold 1, then the second feedback information is a positive acknowledgment. If the ratio X / Y of positive acknowledgments in the first feedback information received by the first device is less than, equal to, or less than threshold 2, then the second feedback information includes one or more of the following: a negative acknowledgment; the second device identifier corresponding to the positive acknowledgment in the first feedback information; or the second device identifier corresponding to the second device for which no positive acknowledgment was received.

[0164] In some implementations, threshold 1 may be the same as or different from threshold 2. Threshold 1 and / or threshold 2 are configured or pre-configured by the network or predefined by a standard or depend on the implementation of the first device.

[0165] The embodiments of the present application are applicable to a scenario in which a first device provides services for multiple second devices, and the multiple second devices send first feedback information on multiple independent resources.

[0166] Example 3: Assuming that the feedback mode corresponding to the first feedback information is to only feedback negative acknowledgments, if the number X of negative acknowledgments in the first feedback information received by the first device is greater than (or equal to, or greater than or equal to) a threshold of 1, then the second feedback information includes one or more of the following: a negative acknowledgment; the second device identifier corresponding to the negative acknowledgment in the first feedback information; and the second device identifier corresponding to the second device for which no negative acknowledgment was received. If the number X of negative acknowledgments in the first feedback information received by the first device is less than (or equal to, or less than or equal to) the second threshold, then the second feedback information is a positive acknowledgment.

[0167] In some implementations, threshold 1 may be the same as or different from threshold 2. Threshold 1 and / or threshold 2 are configured or pre-configured by the network or predefined by a standard or depend on the implementation of the first device.

[0168] The embodiments of the present application are applicable to a scenario in which a first device provides services for multiple second devices, and the multiple second devices send first feedback information on multiple independent resources.

[0169] Example 4: Assuming that the feedback mode corresponding to the first feedback information is to only feedback negative acknowledgments, if the ratio X / Y of negative acknowledgments in the first feedback information received by the first device is greater than (or equal to, or greater than or equal to) a threshold of 1, then the second feedback information includes one or more of the following: a negative acknowledgment; the second device identifier corresponding to the negative acknowledgment in the first feedback information; and the second device identifier corresponding to the second device for which no negative acknowledgment was received. If the ratio X / Y of negative acknowledgments in the first feedback information received by the first device is less than (or equal to, or less than or equal to) the second threshold, then the second feedback information is a positive acknowledgment.

[0170] In some implementations, threshold 1 may be the same as or different from threshold 2. Threshold 1 and / or threshold 2 are configured or pre-configured by the network or predefined by a standard or depend on the implementation of the first device.

[0171] The embodiments of the present application are applicable to a scenario in which a first device provides services for multiple second devices, and the multiple second devices send first feedback information on multiple independent resources.

[0172] Example 5: Assume that the feedback mode corresponding to the first feedback information is to feedback both positive and negative acknowledgments. If the number of positive acknowledgments X in the first feedback information received by the first device is greater than (or equal to, or greater than or equal to) threshold 1, then the second feedback information is a positive acknowledgment. If the number of negative acknowledgments Z in the first feedback information received by the first device is greater than (or equal to, or greater than or equal to) threshold 2, then the second feedback information includes one or more of the following: a negative acknowledgment; a second device identifier corresponding to the positive acknowledgment in the first feedback information; a second device identifier corresponding to the second device for which no positive acknowledgment was received.

[0173] In some implementations, threshold 1 may be the same as or different from threshold 2. Threshold 1 and / or threshold 2 are configured or pre-configured by the network or predefined by a standard or depend on the implementation of the first device.

[0174] The embodiments of the present application are applicable to a scenario in which a first device provides services for multiple second devices, and the multiple second devices send first feedback information on multiple independent resources.

[0175] Example 6: Assume that the feedback mode corresponding to the first feedback information is to feedback both positive and negative responses. If the ratio X / Y of positive responses in the first feedback information received by the first device is greater than (or equal to, or greater than or equal to) a threshold value 1, then the second feedback information is a positive response. If the ratio Z / Y of negative responses in the first feedback information received by the first device is greater than (or equal to, or greater than or equal to) a second threshold value, then the second feedback information includes one or more of the following: a negative response; a second device identifier corresponding to the positive response in the first feedback information; a second device identifier corresponding to the failure to receive a positive response in the first feedback information.

[0176] In some implementations, threshold 1 may be the same as or different from threshold 2. Threshold 1 and / or threshold 2 are configured or pre-configured by the network or predefined by a standard or depend on the implementation of the first device.

[0177] The embodiments of the present application are applicable to a scenario in which a first device provides services for multiple second devices, and the multiple second devices send first feedback information on multiple independent resources.

[0178] The following describes the first feedback information and second feedback information in an embodiment of the present application in conjunction with Figure 9. As shown in Figure 9, assume that the first device is an intermediate node and the second device is A-IoT devices 1 to 3. The network device sends a first command to the first device, and in response, the first device sends a second command to A-IoT devices 1 to 3. Accordingly, A-IoT devices 1 to 3 send the first feedback information to the first device on three independent resources.

[0179] In some implementations, the first device may multicast or broadcast the second command to the A-IoT devices 1 to 3 on the same resource. Of course, in the embodiment of the present application, the first device may transmit the second command to the A-IoT devices 1 to 3 respectively on different resources.

[0180] In Scenario 1, the first feedback information is sent as an affirmative response only. For each A-IoT device, upon successfully receiving or executing the second command, the A-IoT device may send a positive response to the intermediate node. Conversely, if the A-IoT device fails to receive or execute the second command, it does not send the first feedback information.

[0181] Exemplarily, if the number of positive responses in the first feedback information received by the first device is 3 or the ratio of positive responses is 1, it is determined that the second feedback information is a positive response.

[0182] Exemplarily, if the number of positive acknowledgments received by the first device is less than 3 or the proportion of positive acknowledgments is less than 1, the second feedback information is determined to include one or more of the following: a negative acknowledgment; the second feedback information is determined to be the A-IoT device identifier corresponding to the received positive acknowledgment; or the second feedback information is determined to be the A-IoT device identifier corresponding to the non-received positive acknowledgment. If A-IoT devices 1 and 2 provide positive acknowledgments, and A-IoT device 3 does not send the first feedback information, the second feedback information may include the identifiers of A-IoT devices 1 and 2, or the second feedback information may include the identifier of A-IoT device 3.

[0183] In scenario 2, the first feedback information is fed back as a negative acknowledgment only. For each A-IoT device, if the A-IoT device fails to successfully receive or execute the second command, the first feedback information it sends to the intermediate node may be a negative acknowledgment. If the A-IoT device successfully receives or executes the second command, it does not send the first feedback information.

[0184] Exemplarily, if the number of negative responses in the first feedback information received by the first device is greater than or equal to 1 or the proportion is greater than or equal to 1 / 3, then the second feedback information is determined to include one or more of the following: a negative response, determining that the second feedback information is the A-IoT device identifier corresponding to the received negative response, and determining that the second feedback information is the A-IoT device identifier corresponding to the non-received negative response. If A-IoT devices 1 and 2 feedback negative responses and A-IoT device 3 does not send the first feedback information, then the second feedback information is the identifier of A-IoT devices 1 and 2 or the second feedback information is the identifier of A-IoT device 3.

[0185] Exemplarily, if the number or proportion of negative acknowledgments in the first feedback information received by the first device is 0, it is determined that the second feedback information is a positive acknowledgment.

[0186] In scenario 3, the first feedback information corresponds to a positive or negative response. For each A-IoT device, the A-IoT device returns a positive response when it successfully receives or executes the second command, and returns a negative response when it fails to receive or execute the second command.

[0187] Exemplarily, if the number of positive acknowledgements in the first feedback information received by the first device is equal to 3 or the ratio of positive acknowledgements is equal to 1, it is determined that the second feedback information is a positive acknowledgement.

[0188] Exemplarily, if the number of negative responses in the first feedback information received by the first device is greater than or equal to 1, the second feedback information is determined to be a negative response, or the second feedback information is determined to be the A-IoT device identifier corresponding to the positive response, or the second feedback information is determined to be the A-IoT device identifier corresponding to the failure to receive a positive response. For example, A-IoT devices 1 and 2 feedback a positive response, and A-IoT device 3 feedbacks a negative response, then the second feedback information is the identifier of A-IoT devices 1 and 2 or the identifier of A-IoT device 3.

[0189] Example 7: Assume that the feedback mode corresponding to the first feedback information is to only feedback a negative acknowledgment. If the first device detects a negative acknowledgment on the resource receiving the first feedback information or the detected receiving power is greater than or equal to (or greater than, or equal to) threshold 1, then the second feedback information is a negative acknowledgment. If the first device does not detect a negative acknowledgment on the resource receiving the first feedback information or the detected receiving power is less than (or less than or equal to, or equal to) threshold 2, then the second feedback information is a positive acknowledgment.

[0190] In some implementations, threshold 1 may be the same as or different from threshold 2. Threshold 1 and / or threshold 2 are configured or pre-configured by the network or predefined by a standard or depend on the implementation of the first device.

[0191] The embodiment of the present application is applicable to a scenario where a first device provides services to multiple second devices, and the multiple second devices send first feedback information on multiple independent resources. Of course, in the embodiment of the present application, the second devices can send the first feedback information on the same resource.

[0192] The following continues to introduce the first feedback information and the second feedback information in the embodiment of the present application in conjunction with Figure 9. As shown in Figure 9, it is assumed that the first device is an intermediate node and the second device is A-IoT devices 1 to 3. The network device sends a first command to the first device, and accordingly, the first device sends a second command to A-IoT devices 1 to 3. Accordingly, A-IoT devices 1 to 3 send the first feedback information to the first device on three independent resources respectively. Of course, in the embodiment of the present application, A-IoT devices 1 to 3 can also send the first feedback information to the first device on the same resource.

[0193] Assume that the feedback mode corresponding to the first feedback information is to only provide a negative response. For each A-IoT device, if the A-IoT device fails to successfully receive or execute the second command, the first feedback information sent to the first device is a negative response. If the A-IoT device successfully receives or executes the second command, it does not send the first feedback information.

[0194] Exemplarily, if the first device does not detect a negative acknowledgement on the resource for receiving the first feedback information or the detected receiving power is less than a configured threshold, it determines that the second feedback information is a positive acknowledgement.

[0195] Exemplarily, if the first device detects a negative acknowledgement on the resource for receiving the first feedback information or the detected receiving power is greater than or equal to a configured threshold, it determines that the second feedback information is a negative acknowledgement.

[0196] Example 8: If the first device determines, based on the received first feedback information, that the first command was fulfilled, the second feedback information is a positive response. If the first device determines, based on the received first feedback information, that the first command was not fulfilled, the second feedback information is a negative response. The first command is indicated to the first device by the network device.

[0197] The following continues to describe the first feedback information and second feedback information in the embodiment of the present application in conjunction with Figure 9. As shown in Figure 9, assume that the first device is an intermediate node and the second device is A-IoT devices 1 to 3. The network device sends a first command to the first device, and in response, the first device sends a second command to A-IoT devices 1 to 3. Accordingly, A-IoT devices 1 to 3 send the first feedback information to the first device on three independent resources.

[0198] As shown in Figure 9, assuming that the network device sends a first command to the intermediate node, and the intermediate node sends a second command to the A-IoT device, one intermediate node corresponds to three A-IoT devices.

[0199] In Scenario 1, the first feedback information corresponds to a positive response only. For each A-IoT device, upon successfully receiving or executing the second command, the A-IoT device may send a positive response to the intermediate node. If the A-IoT device fails to receive or execute the second command, it will not send the first feedback information.

[0200] In scenario 2, the first feedback information corresponds to a negative acknowledgment only. For each A-IoT device, if it fails to successfully receive or execute the second command, the A-IoT device may send a negative acknowledgment as the first feedback information to the intermediate node. If it successfully receives or executes the second command, the A-IoT device does not send the first feedback information.

[0201] In scenario 3, the first feedback information corresponds to both a positive and negative response. For each A-IoT device, upon successfully receiving or executing the second command, the A-IoT device may send a positive response as the first feedback information to the intermediate node. Upon unsuccessful reception or execution of the second command, the A-IoT device may send a negative response as the first feedback information.

[0202] If the intermediate node determines, based on the received first feedback information, that the first command was fulfilled, then the second feedback information is determined to be a positive response. For example, if the first feedback information determines that all three second commands were fulfilled, or that the target command among the three second commands was fulfilled, then the second feedback information is a positive response. Exemplarily, the target command is indicated or configured by the network device or depends on the implementation of the intermediate node.

[0203] If the intermediate node determines, based on the received first feedback information, that the first command was not fulfilled, then the second feedback information is determined to be a negative acknowledgment. For example, if the first feedback information determines that at least one of the three second commands was not fulfilled, or that the target command among the three second commands was not fulfilled, then the second feedback information is determined to be a negative acknowledgment. Exemplarily, the target command is indicated or configured by the network device or is implemented by the intermediate node.

[0204] The intermediate node sends the second feedback information determined above to the network, where the second feedback information includes one or more of the following: a positive response; a negative response; and an identifier of the A-IoT device.
