A-IoT is a new IoT technology. Compared with traditional IoT technology, a significant feature is that the number of A-IoT terminals (A-IoT UE, which can also be called A-IoT device or A-IoT tag) in the network is huge, which can inventory and monitor large-scale items. Compared with NB-IoT terminals, A-IoT terminals have simpler structures, lower hardware costs and maintenance costs, and the entire device can have power devices or not. In the current discussion, A-IoT devices can be divided into three types: type A, type B, and type C. Among them, type A devices (device type A) do not support energy storage and mainly work based on backscatter. They have the lowest complexity and low power consumption. Although type A devices do not support energy storage, they still need to receive wireless signals to activate the internal receiving and processing modules. Type B devices (device type B) support energy storage and work based on backscatter. Their complexity and power consumption are higher than type A devices, but still maintain a relatively low level. Type B devices can store energy, but their energy storage capacity is generally limited. Type C devices support energy storage and work based on active transmission, that is, type C devices can amplify and transmit information through power amplifiers.

A-IoT technology is applicable to various production and life scenarios such as smart logistics, smart warehousing, and factory automation. These production scenarios have one thing in common, that is, the types of materials or items are relatively complex and the quantity is huge. In these scenarios, taking inventory of materials or items within the networking range is an important application of A-IoT technology. Compared with traditional NR communication, the inventory communication of massive devices is more centralized and more regular. More centralized means that when the user triggers the inventory, taking the overall inventory as an example, all devices in the cell need to feedback the inventory information within a certain time range. More regular means that for the network to periodically understand the status of the items or materials attached to the device, it is necessary to trigger the inventory regularly. The triggering method of the device inventory can be periodic triggering or immediate triggering. Periodic triggering is suitable for periodically monitoring the status of materials or items attached to the device, which helps users obtain reference information for overall arrangements. For device type A or device type B, due to the limited power supply capacity, they can only rely on RF equipment for periodic control; for device type C, you can try to configure the trigger period, and device type C will report information periodically. Immediate triggering, or non-periodic triggering, is actually the same as periodic triggering for device type A or device type B, and is implemented by the base station, while for device type C, it may involve scheduling similar to paging.

In the prior art, the A-IoT networking modes mainly include the following: the base station is directly connected to the A-IoT device, and the two parties can communicate uplink and downlink; the base station is connected to the intermediate node, and the two communicate uplink and downlink, and the intermediate node is connected to the A-IoT device, and the two communicate uplink and downlink. Furthermore, the base station and the A-IoT device cannot communicate through uplink or downlink; the base station is connected to the A-IoT device through an auxiliary node, and the two communicate downlink, and the base station is connected to the A-IoT device, and the two communicate uplink; the terminal is connected to the A-IoT device, and the two communicate uplink and downlink, that is, the terminal can replace the base station to connect to the A-IoT device.

The communication process between A-IoT devices is as follows: A-IoT network devices send downlink signaling on the downlink channel to trigger communication with A-IoT devices. For device type A or device type B, each group of devices (each group of devices contains at least one device) can reflect the signal to different sub-channels. For device type C, each group of devices can be configured to correspond to different sub-channels. The communication between different devices in different sub-channels can avoid interference between adjacent sub-channels through network deployment and network device configuration. For example, the base station BS, UE terminal, intermediate node or auxiliary node X note can send downlink signaling DL and trigger devices 1, 2, and 3 at the same time. The three devices perform uplink transmission on sub-uplink channels 1, 2, and 3 respectively. The specific communication process is shown in Figure 7.

When A-IoT technology is used to inventory and monitor large-scale items or materials. There are many A-IoT devices, and the communication between A-IoT devices needs to meet the condition of being able to handle massive amounts of communication data. In addition, ensuring high reliability and reducing inventory latency are all potential A-IoT device design goals. Different design goals have different requirements for A-IoT devices. For example, a large number of devices require the coordination of the network when scheduling radio frequency equipment; for high reliability requirements, in addition to meeting coverage, transmission power, etc., it is also necessary to solve collision problems, or minimize collisions; to reduce inventory latency, the communication between A-IoT devices needs to respond as quickly as possible to avoid failure of some devices. The overall inventory delay caused by this.

In view of the above technical goals, this solution proposes two design ideas, one is to schedule A-IoT devices based on device grouping, and the other is to schedule A-IoT devices based on dynamic scheduling sequence numbers. The specific contents of this solution are as follows.

FIG2 is an interactive schematic diagram of a communication method based on the ambient Internet of Things according to an embodiment of the present disclosure. As shown in FIG2, the embodiment of the present disclosure relates to a communication method based on the ambient Internet of Things, which is used in a communication system 100. The communication system 100 may include an A-IOT network device 101 and a first A-IOT terminal device 102. The method includes:

Step 2101a, the A-IOT network device determines a first scheduling sequence number of a first A-IOT terminal device.

In some embodiments, the first A-IOT terminal device may have one or more scheduling numbers.

In some embodiments, the first scheduling sequence number can be used by the A-IOT network device to schedule the first A-IOT terminal device.

In some embodiments, determining the first scheduling sequence number of the first A-IOT terminal device may include at least one of the following: determining the first scheduling sequence number written into the first A-IoT terminal device at the factory stage; determining the first scheduling sequence number written into the first A-IoT terminal device at the registration stage; determining at least one first scheduling sequence number that is the default of the first A-IoT terminal device; and determining that the A-IoT network device configures the first scheduling sequence number for the first A-IoT terminal device based on the configuration signaling of the A-IoT network device. That is, the first scheduling sequence number can be written into the first A-IoT terminal device at different stages based on the protocol pre-definition, and both the first A-IOT terminal device and the A-IOT network device can obtain the written information; or, the protocol can pre-define a default first scheduling sequence number, and the first A-IOT terminal device and the A-IOT network device can determine the first scheduling sequence number according to the protocol pre-definition; or the A-IoT network device can dynamically configure the first scheduling sequence number for the first A-IOT terminal device by sending a configuration signaling to the first A-IOT terminal device.

In some embodiments, the first scheduling number written in the factory stage and the registration stage and the default first scheduling number predefined according to the protocol cannot be rewritten; however, the first scheduling number configured by the A-IoT network device for the first A-IOT terminal device can be updated.

In some embodiments, the method described in step 2101a is also applicable to the A-IOT terminal device side, that is, it is also applicable to step 2101b.

Step 2101b: The first A-IOT terminal device determines a first scheduling sequence number of the first A-IOT terminal device.

In some embodiments, the method by which the first A-IOT terminal device determines the first scheduling number of the first A-IOT terminal device is consistent with the method by which the A-IOT network device determines the first scheduling number of the first A-IOT terminal device, that is, step 2101b can refer to the content described in step 2101a.

In some embodiments, the execution order of step 2101b and step 2101a can be swapped or can be executed simultaneously.

Step 2102: The A-IOT network device determines a first time interval.

In some embodiments, the first time interval is the time required for an A-IOT terminal device within a scheduling group to complete the entire scheduling, and is also the feedback timing required by the A-IoT network device, that is, the maximum time the A-IoT network device waits for the A-IoT terminal device to complete backscattering after sending a downlink signaling.

In some embodiments, the measurement unit of the first time interval may be an absolute time unit or a relative time unit.

The absolute time unit includes but is not limited to at least one of the following: nanosecond ns, microsecond us, millisecond ms, second s, minute min, etc.

Relative time units include, but are not limited to, time domain symbols, time slots, radio subframes, radio frames, radio half frames, etc.

In some embodiments, the tasks that need to be processed before sending feedback for type A and type B A-IoT devices may include charging, starting backscattering, etc., and the tasks that need to be processed for type C A-IoT devices may include decoding signaling, uplink preparation, etc.

In some embodiments, the A-IOT network device can determine a first time interval, where the first time interval can be predefined by a protocol; or the A-IOT network device can determine a first interval range, where the first interval range can be predefined by a protocol, and the A-IOT network device receives the processing capability reported by at least one A-IOT terminal device; based on the processing capability, determine the first time interval in the first interval range.

In some embodiments, when the A-IOT network device determines the first time interval range, the A-IOT terminal device can report the processing capacity, where the processing capacity can be the time required for the above-mentioned A-IoT terminal device to process the task before providing feedback. After receiving the processing capacity reported by the A-IOT terminal device, the A-IOT network device can determine the time required for the longest task and determine the first time interval to be a value greater than or equal to the time.

In some embodiments, when the first time interval is greater than or equal to the time required for the task before the A-IOT terminal device performs feedback, the A-IOT network device can receive the feedback information within the first time interval, and when the first time interval is less than the time required for the above task, the A-IOT network device may not receive the feedback information within the first time interval.

In some embodiments, the A-IOT network device may determine the first time interval without receiving the processing capacity reported by the A-IOT terminal device. For example, the A-IOT network device may determine a fixed first time interval based on a predefined protocol; or the A-IOT network device may determine After a first time interval range is determined, a maximum value in the range is selected as the value of the first time interval.

Step 2103: The A-IOT network device sends downlink signaling to at least one A-IOT terminal device within a first time interval.

In some embodiments, the downlink signaling may be used to schedule a first A-IOT terminal device among at least one A-IOT terminal device.

In some embodiments, the downlink signaling carries the first scheduling number or related information of the first scheduling number. The related information of the first scheduling number can be used to identify the first scheduling number, and the related information of the first scheduling number can also be used to schedule the first A-IOT terminal device in at least one A-IOT terminal device.

In some embodiments, when sending downlink signaling, a scheduling count can be started, and the scheduling count can be used by the A-IoT network device to monitor the scheduling process.

In the above embodiment, when the scheduling count is accumulated from the first initial value to the first termination value, the scheduling process ends; or, when the scheduling count is decreased from the second initial value to the second termination value, the scheduling process ends.

In the above embodiment, the first initial value and/or the second termination value is the first value or the second value, and the first termination value and/or the second initial value is the maximum scheduling sequence number of the first A-IoT terminal device or the maximum scheduling sequence number minus one.

In the above embodiments, the maximum value of the scheduling sequence number is any one of the following: a maximum value predefined by the protocol, that is, the protocol can directly define a maximum value of a scheduling sequence number; a maximum value in a set of maximum values supported by each first A-IoT terminal device, that is, the A-IOT network device can obtain the maximum values of the scheduling sequence numbers supported by all first A-IoT terminal devices, and determine that the largest scheduling sequence number among the obtained maximum values is the above-mentioned maximum value of the scheduling sequence number; a maximum value configured by the A-IoT network device, that is, the network device can directly configure a maximum value of a scheduling sequence number.

In some embodiments, within a first time interval, the A-IOT network device may continuously send downlink signaling to at least one A-IOT terminal device, or send downlink signaling M times to at least one A-IOT terminal device, where M is a positive integer, and the first time interval is the maximum duration that the A-IOT network device waits for the first A-IOT terminal device to complete scheduling.

In some embodiments, the A-IOT network device may also continuously send a charging signal to at least one A-IOT terminal device, or send a charging signal M times to at least one A-IOT terminal device. The charging signal may be used to charge the A-IOT terminal device, and the charging signal does not carry information.

In the above embodiment, the downlink signaling can also be used as a charging signal to charge the A-IOT terminal device.

Step 2104a: The A-IOT network device determines an uplink channel corresponding to the first A-IOT terminal device.

In some embodiments, based on the transmission frequency of the downlink signaling, the first backscatter offset of the first A-IoT terminal device and/or the reverse scatter frequency domain direction of the first backscatter offset, the uplink channel corresponding to the first A-IOT terminal device is determined. At this time, the first backscatter offset is one of the N backscatter offsets supported by the first A-IoT terminal device, and the reverse scatter frequency domain direction of each backscatter offset is fixed, and N is a positive integer. Preferably, N can be equal to 1.

In some embodiments, the first backscatter offset is used to determine the frequency at which the first A-IOT terminal device sends uplink data. The first backscatter offset can be achieved by backscattering the downlink signaling received by the first A-IOT terminal device to a specific frequency point, which is the frequency at which the first A-IOT terminal device sends uplink data.

In some embodiments, the backscatter frequency domain direction of the first backscatter offset can be used to determine the offset direction of the first backscatter offset. For example, when the backscatter frequency domain direction of the first backscatter offset is upward, the first backscatter offset can be offset toward a higher frequency; when the backscatter frequency domain direction of the first backscatter offset is downward, the first backscatter offset can be offset toward a lower frequency.

In some embodiments, the backscatter offset and/or the backscatter frequency domain direction of each backscatter offset may be confirmed at the factory stage or the registration stage.

In some embodiments, the A-IOT network device can send trigger information to the A-IOT terminal device, and the trigger information can be used to trigger the first A-IOT terminal device to measure the channel quality and feedback the channel quality; the A-IOT terminal device can feedback the channel quality to the A-IOT network device; the A-IOT network device can determine the uplink channel corresponding to the first A-IOT terminal device based on the channel quality. At this time, the first backscatter deviation and the backscatter frequency domain direction of each backscatter deviation can be configured by the A-IOT network device. In some embodiments, the above-mentioned channel quality measurement refers to measuring the reference signal transmitted by the channel, and the obtained measurement results, such as RSRP, RSRQ, etc., can reflect the channel quality.

In some embodiments, the uplink channel determination method described in this step is also applicable to the A-IOT terminal device side, that is, it is also applicable to step 2104b.

Step 2104b: The first A-IOT terminal device determines an uplink channel corresponding to the first A-IOT terminal device.

In some embodiments, the method for the first A-IOT terminal device to determine the uplink channel corresponding to the first A-IOT terminal device is similar to the method for the A-IOT network device to determine the uplink channel corresponding to the first A-IOT terminal device. The method on the network device side is consistent with that on the network device side, that is, the specific method described in step 2104a can be referred to.

In some embodiments, the execution order of step 2104a and step 2104b can be swapped or can be executed simultaneously.

Step 2105a: The A-IOT network device determines a grouping of at least one A-IOT terminal device.

In some embodiments, grouping the A-IOT terminal devices may include at least one of grouping based on channels and grouping based on scheduling numbers.

In some embodiments, the channel grouping based method may include at least one of the following:

Allocate A-IoT terminal devices that can use the same uplink channels into one group. For example, A-IOT terminal device 1 can use channels 1 and 2, A-IOT terminal device 2 can use channels 1, 2, and 3, A-IOT terminal device 3 can use channel 1, and A-IOT terminal device 4 can use channels 1 and 2. Then A-IOT terminal device 1 and A-IOT terminal device 4 can be grouped together.

Allocate A-IoT terminal devices with the same at least one uplink sub-channel that can be used into a group. For example, in the above example, A-IOT terminal devices 1, 2, 3, and 4 can be grouped into one group.

Assign A-IoT terminal devices with the same backscatter offset to a group;

A-IoT terminal devices with the same backscatter offset and the same backscatter frequency domain direction of the backscatter offset are assigned to one group;

Allocate A-IoT terminal devices with a backscatter offset of a preset value into a group;

Assigning A-IoT terminal devices whose backscatter offsets fall within a preset range to a group;

Assigning A-IoT terminal devices with adjustable backscatter offset to a group;

Assign A-IoT terminal devices with the same channel quality to a group;

A-IoT terminal devices whose channel quality meets preset conditions are assigned to a group.

In some embodiments, the method of grouping based on scheduling sequence numbers may include at least one of the following:

All A-IoT terminal devices with the same scheduling sequence number are assigned to one group. For example, if the scheduling sequence numbers corresponding to A-IOT terminal device 1 are 1 and 2, the scheduling sequence numbers corresponding to A-IOT terminal device 2 are 1, 2, and 3, the scheduling sequence number corresponding to A-IOT terminal device 3 is 1, and the scheduling sequence number corresponding to A-IOT terminal device 4 is 1 and 2, then A-IOT terminal device 1 and A-IOT terminal device 4 can be grouped together;

Assign at least one A-IoT terminal device with the same scheduling sequence number to a group. For example, in the above example, A-IOT terminal devices 1, 2, 3, and 4 can be grouped together.

Configure at least one same scheduling sequence number for A-IoT terminal devices with the same channel quality;

Configure the same scheduling sequence number for A-IoT terminal devices with the same channel quality;

Configure at least one identical scheduling sequence number for A-IoT terminal devices whose channel quality meets the preset conditions;

A-IoT terminal devices whose channel quality meets the preset conditions are configured with the same scheduling number.

In some embodiments, the method described in this step is also applicable to the A-IOT terminal device side, that is, it can also be applied to step 2105b.

In some embodiments, this step is an optional step, that is, the A-IOT network device may not determine the grouping of at least one A-IOT terminal device.

Step 2105b: The first A-IOT terminal device determines a group of at least one A-IOT terminal device.

In some embodiments, the method by which the first A-IOT terminal device determines the grouping of at least one A-IOT terminal device is consistent with that on the A-IOT network device side, that is, the method described in step 2105a may be referred to.

In some embodiments, the execution order of step 2105a and step 2105b can be swapped or can be executed simultaneously.

In some embodiments, this step is an optional step, that is, the first A-IOT terminal device may not determine the grouping of at least one A-IOT terminal device.

Step 2106: The first A-IOT terminal device determines that the first A-IOT terminal device is scheduled.

In some embodiments, when the downlink signaling carries the first scheduling sequence number of the first A-IOT terminal device, it can be determined that the first A-IOT terminal device is scheduled.

In some embodiments, this step is an optional step. When the downlink signaling does not carry the first scheduling sequence number of the first A-IOT terminal device, the first A-IOT terminal device may not be scheduled.

Step 2107: The A-IOT network device determines a second time interval.

In some embodiments, the second time interval is the longest time required for an A-IoT terminal device that has not completed the scheduling within the first time interval to complete the entire scheduling.

In some embodiments, the measurement unit of the second time interval may be an absolute time unit or a relative time unit.

The absolute time unit includes but is not limited to at least one of the following: nanosecond ns, microsecond us, millisecond ms, second s, minute min, etc.

Relative time units include, but are not limited to, time domain symbols, time slots, radio subframes, radio frames, radio half frames, etc.

In some embodiments, the second time interval may be predefined by a protocol, that is, the protocol may directly predetermine a second time interval.

In some embodiments, a second interval range can be determined, wherein the second interval range is predefined by a protocol; the A-IOT network device can receive processing capabilities reported by at least one A-IOT terminal device; and based on the processing capabilities, a second time interval is determined in the second interval range.

The processing capacity can be the time required for the A-IoT terminal device to process a task before providing feedback. After receiving the processing capacity reported by the A-IOT terminal device, the A-IOT network device can determine the time required for the longest task and determine the second time interval to be greater than or equal to the time.

In some embodiments, when the first time interval is greater than or equal to the time required for the task before the A-IOT terminal device performs feedback, the A-IOT network device can receive the feedback information within the second time interval, and when the second time interval is less than the time required for the above task, the A-IOT network device may not receive the feedback information within the second time interval.

In some embodiments, the A-IOT network device may determine the second time interval without receiving the processing capacity reported by the A-IOT terminal device. For example, the A-IOT network device may determine a fixed second time interval based on protocol predefinition; or the A-IOT network device may determine a second time interval range and then select the maximum value within the range as the value of the second time interval.

In some embodiments, the multiple of the second time interval relative to the first time interval can be determined; the second time interval is determined based on the multiple, for example, the protocol can predefine the multiple as a positive integer L, then the second time interval is L times the first time interval.

In the above embodiment, optionally, the second time interval may be equal to the first time interval.

In some embodiments, this step is an optional step. When the A-IOT network device receives uplink data sent by all A-IoT terminal devices within the first time interval, the second time interval may not be determined, and the scheduling may be ended directly.

Step 2108: The A-IOT network device sends downlink signaling to at least one A-IOT terminal device within the second time interval.

In some embodiments, within the second time interval, the A-IOT network device may continuously send downlink signaling to at least one A-IOT terminal device, or send downlink signaling M times to at least one A-IOT terminal device.

In some embodiments, the A-IOT network device may continuously send downlink signaling to at least one A-IOT terminal device under a second condition and within a second time interval, or send downlink signaling to at least one A-IOT terminal device M times, wherein the second condition is: within the first time interval, the A-IOT network device fails to correctly receive the uplink data sent by the first A-IOT terminal device. That is, when the A-IOT network device fails to correctly receive the uplink data sent by the first A-IOT terminal device, it means that the A-IOT network device has failed to successfully schedule the first A-IOT terminal device within the first time interval. At this time, the downlink signaling may be sent again within the second time interval to schedule the first A-IOT terminal device. At this time, the A-IOT network device may repeat the scheduling of all A-IOT terminal devices without identifying which A-IOT terminal devices have not provided feedback. At this time, the downlink signaling sent in the first time interval and the second time interval may be the same.

In some embodiments, in the second time interval, the A-IOT network device may continuously send downlink signaling or send M downlink signaling to the A-IOT terminal device that did not feedback uplink data in the first time interval, wherein the downlink signaling carries the identifier of the A-IOT terminal device that did not feedback uplink data in the first time interval. That is, the A-IOT network device can identify the A-IOT terminal device that did not provide feedback in the first time interval, and carry the identifier of its corresponding A-IOT terminal device in the downlink signaling sent in the second time interval, and reschedule the A-IOT terminal device that did not provide feedback, and no longer reschedule the A-IOT terminal device that has already provided feedback.

In some embodiments, this step is an optional step. When the A-IOT network device receives uplink data sent by all A-IoT terminal devices within a first time interval, the A-IOT network device does not need to send downlink signaling to at least one A-IOT terminal device within a second time interval for scheduling again.

Step 2109: The first A-IOT terminal device sends uplink data to the A-IOT network device.

In some embodiments, the first A-IOT terminal device may send uplink data to the A-IOT network device upon confirming that it is scheduled.

In some embodiments, the uplink data can be used to provide feedback that the first A-IOT terminal device has been successfully scheduled, and can also be used to upload other data.

In some embodiments, the name of the uplink data may be “feedback data”, “measurement data”, etc., which is not limited in the present disclosure.

Step 2110: The A-IOT network device determines that the current scheduling is completed under the first condition.

In some embodiments, the first condition may be at least one of the following:

In the first time interval, the A-IOT network device fails to correctly receive the uplink data sent by the first A-IOT terminal device. In the second time interval, the A-IOT network device receives the uplink data sent by the first A-IOT terminal device, that is, the A-IOT terminal device receives the uplink data sent by the first A-IOT terminal device in the first time interval. The feedback is not fully completed within the second time interval, and the feedback is fully completed within the second time interval. At this time, the A-IOT network device receives the uplink data sent by the first A-IOT terminal device, which may mean that the A-IOT network device has not received all the uplink data of the A-IOT terminal device;

The first time interval and the second time interval end;

The scheduling count of the A-IOT network device is accumulated from a first initial value to a first termination value;

The scheduling count of the A-IOT network device decreases from the second initial value to the second termination value;

The first time interval ends. At this time, within the first time interval, regardless of whether the A-IOT network device receives uplink data sent by all scheduled A-IOT terminal devices, it is determined that the scheduling is ended;

The first time interval and the second time interval end, and the A-IOT network device receives the uplink data sent by the first A-IOT terminal device within the first time interval and/or the second time interval. At this time, the scheduling conditions of the two time intervals can be comprehensively considered. Only when all the A-IOT network devices receive the uplink data sent by the scheduled A-IOT terminal devices within the two time intervals, can it be determined that this scheduling is over.

The following is an exemplary introduction to the above method.

The method shown in the embodiment of the present disclosure relates to a system and method suitable for communication between A-IoT devices.

An important application of A-IoT technology is to inventory and monitor large-scale items/materials. In order to meet the actual application requirements, A-IoT In addition to being able to handle massive amounts of communication data, communication between devices also requires high reliability of communication and reduced inventory latency, which are potential design goals for A-IoT devices. Further breakdown of technical goals: devices that can handle massive amounts of communication require RF devices to play a coordinating role in the network when scheduling; high reliability of communication between devices, that is, in addition to meeting coverage, transmission power, etc., collisions must also be resolved, or collisions must be as few as possible; in order to reduce inventory latency, A-IoT devices must respond as quickly as possible to avoid overall inventory delays caused by failures of some devices.

In view of the above technical goals, this solution considers two design ideas, one is scheduling based on device grouping, and the other is scheduling based on dynamic scheduling numbers.

Embodiment 1: This example can implement the scheduling of A-IoT terminal devices by A-IoT network devices through a "stop and wait" method, that is, after the A-IoT network device issues a scheduling instruction to an A-IoT terminal device, the feedback of the A-IoT terminal device can be processed in real time.

In a network, an A-IoT network device communicates with an A-IoT terminal device. The A-IoT network device may include a base station, a terminal, an intermediate node, an auxiliary node, etc. The types of the A-IoT terminal device may include type A, type B, and type C. The A-IoT network device sends an excitation signal to at least one A-IoT terminal device, and the excitation signal can be used to trigger the communication of the A-IoT terminal device, such as transmitting control signaling, data, etc. Optionally, the excitation signal can also serve as a charging energy source for the A-IoT terminal device.

The communication process between the A-IoT network device and the A-IoT terminal device includes at least one of the following:

1. In the network, channel grouping is performed for all or part of the A-IoT terminal devices.

Furthermore, the A-IoT terminal device grouping method includes at least one of the following:

1. Allocate the A-IoT terminal devices that can use all the same uplink sub-channels into a group, that is, the A-IoT terminal devices that can use all the same uplink sub-channels can be regarded as a channel group, and the A-IoT terminal devices can use at least one sub-channel or channel.

2. A-IoT terminal devices that can use at least one same uplink sub-channel are assigned to a group, that is, A-IoT terminal devices that can use at least one same uplink sub-channel are regarded as a channel group, and the A-IoT terminal devices can use at least one sub-channel or channel.

3. Assign A-IoT terminal devices with the same backscatter offset value to a channel group; or assign A-IoT terminal devices with the same backscatter offset value and the same backscatter frequency domain direction to a channel group, that is, A-IoT terminal devices with the same backscatter offset value and the same backscatter frequency domain direction can be regarded as a channel group.

4. Assign the A-IoT terminal devices with fixed backscatter offset values to a channel group, that is, the A-IoT terminal devices with fixed backscatter offset values can be regarded as a channel group.

5. Assign the A-IoT terminal devices whose backscatter offset values can be adjusted to a channel group, that is, the A-IoT terminal devices whose backscatter offset values can be adjusted can be regarded as a channel group.

As shown in Figure 6, the A-IoT terminal devices correspond to different tags, and the backscatter offset of each tag is fixed, that is, when the received excitation signal is constant, the uplink subchannel corresponding to each tag is fixed. In the figure, Tag1-1 to Tag1-5 is a channel group, Tag2-1 to Tag2-5 is a channel group, and Tag3-1 to Tag3-5 is a channel group. The channel group number corresponding to the A-IoT terminal device corresponding to each channel group is the same.

2. In the network, all or part of the A-IoT terminal devices are scheduled and grouped.

Each A-IoT terminal device may be assigned at least one scheduling sequence number. Optionally, each A-IoT terminal device may be assigned a unique scheduling sequence number.

Furthermore, the A-IoT terminal device grouping method includes at least one of the following:

2. Assign at least one A-IoT terminal device with the same scheduling sequence number to a scheduling group, that is, at least one A-IoT terminal device with the same scheduling sequence number is regarded as a scheduling group.

The confirmation method of the scheduling sequence number may include at least one of the following:

1) The dispatch sequence number can be written into the A-IoT terminal device when it leaves the factory and will not be changed;

2) The dispatch sequence number can be written into the A-IoT terminal device during the A-IoT terminal device registration phase and will not be changed;

3) The scheduling sequence number can be written into the Tag (A-IoT terminal device) during the A-IoT terminal device registration phase, and the subsequent A-IoT network device can be configured through signaling;

4) The scheduling sequence number can be configured/written by the A-IoT network device after the A-IoT terminal device establishes communication with the A-IoT network device.

In some embodiments, the dispatch sequence number and the authorization to communicate in the network can be combined, that is, the A-IoT terminal device configured with the dispatch sequence number Only then can it communicate with A-IoT network devices in the current network.

As shown in Figure 6, A-IoT terminal devices correspond to different tags, and each tag has a fixed scheduling sequence number. In the figure, Tag1-1 to Tag3-1 is a channel group, Tag1-2 to Tag3-2 is a scheduling group, Tag1-3 to Tag3-3 is a scheduling group, Tag1-4 to Tag3-4 is a scheduling group, and Tag1-5 to Tag3-5 is a scheduling group.

The scheduling count confirmation method includes at least one of the following:

1. The protocol predefines the scheduling count, which is used by the A-IoT network device to monitor the scheduling process. The scheduling count is accumulated from the initial value to the end value. The preferred initial value is 0 or 1, and the end value is the maximum scheduling number or the maximum scheduling number minus 1.

2. The protocol predefines the scheduling count, which is used by the A-IoT network device to monitor the scheduling process. The scheduling count decreases from the initial value to the termination value. The preferred termination value is 0 or 1, and the initial value is the maximum scheduling number or the maximum scheduling number minus 1.

4. When the A-IoT terminal device receives downlink signaling from at least one A-IoT network device and determines that it is scheduled, the A-IoT terminal device performs uplink transmission on at least one corresponding uplink channel/sub-channel.

The manner in which the A-IoT terminal device determines the corresponding at least one uplink channel/sub-channel may include at least one of the following:

1. A-IoT terminal devices only support N fixed backscatter offsets, and the backscatter frequency domain direction of each backscatter offset is fixed. The backscatter offset and/or the backscatter frequency domain direction of each backscatter offset are confirmed at the factory stage or the registration stage. N is a natural number, preferably, N is equal to 1.

2. The backscatter offset of the A-IoT terminal device and/or the backscatter frequency domain direction of each backscatter offset is configured by the A-IoT network device. The A-IoT terminal device supports N backscatter offsets, where N is a natural number. Furthermore, the maximum number Nmax of backscatter offsets supported by the A-IoT terminal device is reported by the A-IoT terminal device to the A-IoT network device. When the A-IoT terminal device does not report Nmax to the A-IoT network device, Nmax defaults to n, and n is preferably equal to 1.

5. During the first time interval, the A-IoT network device continuously sends charging signals and downlink signaling, or the A-IoT network device sends M charging signals and M downlink signaling; the A-IoT network device may also continuously send downlink signaling, or the A-IoT network device may send M downlink signaling; wherein M is an integer not less than 1. Optionally, if during the first time interval, feedback from all scheduled A-IoT terminal devices is received, the A-IoT network device enters the next scheduling. Optionally, if after the end of the first time interval, feedback from all scheduled A-IoT terminal devices is still not received, the A-IoT network device starts the second time interval and sends the charging signal or downlink signaling again.

The first time interval may be confirmed in at least one of the following ways:

Optionally, for type A and type B devices, it may include charging time, startup reflection time, feedback timing required by the A-IoT network device, etc. Optionally, for type C devices, it may include decoding signaling time, uplink preparation time, feedback timing required by BS/UE/X note, etc.

In one implementation, the second time interval is equal to the first time interval, or equal to a multiple of the time interval. For example, the direct protocol predefines a positive integer L, which means that the second time interval is L times the first time interval.

2. The capability is defined by the protocol, and the capability is used to indicate the minimum or maximum value required for the second time interval. The A-IoT terminal device reports the capability to the A-IoT network device. The second time interval is the time required for an A-IoT terminal device in a scheduling group that has not completed the scheduling within the first time interval to complete the entire scheduling. Optionally, for type A and type B devices, it may include charging time, startup reflection time, A-IoT Feedback timing required by the network device, etc. Optionally, for type C devices, it may include the time for decoding signaling, uplink preparation time, feedback timing required by BS/UE/X note, etc.

In one implementation, the second time interval may be equal to the first time interval, or equal to a multiple of the time interval. For example, the A-IoT terminal device directly reports a positive integer L, which means that the second time interval is L times the first time interval.

6. When the second time interval ends, the A-IoT network device enters the next scheduling.

7. When the scheduling count decreases to the termination value (or accumulates to the termination value), it means that the A-IoT network device completes the scheduling of the entire cycle. For the A-IoT terminal device that has not fed back, the status of the A-IoT terminal device is marked as lost or faulty.

Embodiment 2: This example can process the feedback of the A-IoT terminal device after all scheduling is completed.

Steps 1 to 4 of this embodiment are the same as those of the first embodiment.

When the first time interval ends, the A-IoT network device enters the next scheduling.

The first time interval may be confirmed in at least one of the following ways:

1. Directly defined by the protocol. The first time interval is the time it takes for an A-IoT terminal device in a scheduling group to complete the entire scheduling. Optionally, for type A and type B devices, it may include charging time, startup reflection time, feedback timing required by A-IoT network devices, etc. Optionally, for type C devices, it may include signaling decoding time, uplink preparation time, feedback timing required by BS/UE/X note, etc.

2. The capability is defined by the protocol, and the capability is used to indicate the minimum or maximum value required for the first time interval. The A-IoT terminal device reports the capability to the A-IoT network device. The first time interval is the time for an A-IoT terminal device in a scheduling group to complete the entire scheduling. Optionally, for type A and type B devices, it may include charging time, startup reflection time, feedback timing required by the A-IoT network device, etc. Optionally, for type C devices, it may include time for decoding signaling, uplink preparation time, feedback timing required by BS/UE/X note, etc.

6. When the scheduling count decreases to the termination value (or accumulates to the termination value), if there is a missed A-IoT terminal device, the A-IoT network device schedules the missed A-IoT terminal device again.

7. When the number of repeated scheduling for a missed A-IoT terminal device is greater than K and there is still no corresponding uplink data fed back, it is determined that the A-IoT terminal device is lost/faulty.
