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 (device 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, the materials or items within the network range are counted. It 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 if the network needs to periodically understand the status of the items or materials attached to the device, it needs to trigger the inventory regularly. The triggering method of the device inventory can be periodic triggering or instant triggering. Periodic triggering is suitable for periodic monitoring of the status of the materials or items attached to the device, which helps users obtain reference information for overall arrangements. For periodic triggering, for device type A or device type B, due to the lack of its own power supply capacity, it can only rely on radio frequency equipment for periodic control; for device type C, you can try to configure the trigger period, and device type C will report information periodically. Instant 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 process massive communication data. In addition, ensuring high reliability and reducing inventory latency are potential A-IoT device design goals. However, in the actual scheduling process, A-IoT terminal devices are not always able to complete scheduling in the first transmission, and may require secondary or even multiple scheduling. When an A-IoT terminal device needs to be rescheduled, if its scheduling group or scheduling sequence number is not changed, it needs to complete a cycle before it can be rescheduled, which will cause more serious latency problems.

In order to solve the above problems, this solution focuses on designing a scheduling method for A-IoT terminal devices based on dynamic scheduling numbers. By dynamically changing the scheduling numbers of A-IoT terminal devices, the next scheduling can be flexibly arranged for A-IoT terminal devices that have not been successfully scheduled, thereby reducing latency. 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 2101: The A-IoT network device sends a first signaling to a first A-IoT terminal device.

In some embodiments, the first signaling may be used to indicate dynamic scheduling information for the first A-IoT terminal device. The dynamic scheduling information may be used to dynamically schedule the first A-IoT terminal device.

In some embodiments, the name of the dynamic scheduling information may be “feedback indication signaling”, “temporary scheduling information”, “backup scheduling information”, etc., which is not limited by the present disclosure.

In some embodiments, the first A-IoT terminal device belongs to the first scheduling group, and at least one scheduling sequence number of multiple A-IoT terminal devices in the first scheduling group is the same. That is, the A-IoT terminal devices can be grouped based on the scheduling sequence number, and at least one A-IoT terminal device with the same scheduling sequence number can be grouped into one group.

In some embodiments, the bitmap size of the first signaling is N, where N is a positive integer, N is greater than or equal to M, or N is greater than or equal to M is the number of subchannels corresponding to the first scheduling group, is the number of sub-channel groups corresponding to the first scheduling group, each sub-channel group includes m sub-channels, 2≤m≤M.

In some embodiments, there is a correspondence between the bit position of the first signaling and the sub-channel, and the first A-IoT terminal device is the A-IoT terminal device corresponding to the sub-channel, or there is a correspondence between the bit position of the first signaling and the sub-channel group, and the first A-IoT terminal device is the A-IoT terminal device corresponding to the sub-channel group.

In the above embodiment, the bits of the first signaling may correspond to the sub-channels, and the corresponding relationship may be a sub-channel. The subchannels correspond to the bits in the bitmap of the first signaling. Preferably, the subchannels correspond to the bits in the bitmap one by one. For example, the first high bit in the bitmap may correspond to the first subchannel, the second high bit in the bitmap corresponds to the second subchannel, and so on until all subchannels correspond to the bits in the bitmap. Alternatively, further, the first low bit in the bitmap corresponds to the first subchannel, the second low bit in the bitmap corresponds to the second subchannel, and so on until all subchannels correspond to the bits in the bitmap.

In other words, each bit in the bitmap of the first signaling may correspond one-to-one to a subchannel in ascending or descending order.

In some embodiments, the bits of the first signaling may have a corresponding relationship with the sub-channel groups, and the corresponding relationship may be that a sub-channel group corresponds to a bit in a bitmap of the first signaling. For example, the first high bit in the bitmap corresponds to the first sub-channel group, the second high bit in the bitmap corresponds to the second sub-channel group, and so on until all sub-channel groups correspond to the bits in the bitmap. Or, further, the first low bit in the bitmap corresponds to the first sub-channel group, the second low bit in the bitmap corresponds to the second sub-channel group, and so on until all sub-channel groups correspond to the bits in the bitmap.

In other words, each bit in the bitmap of the first signaling may correspond one-to-one to a sub-channel group in ascending or descending order.

In some embodiments, the dynamic scheduling information may include at least one of the following first to eighth information.

The first information is used to indicate whether the uplink data of the first A-IoT terminal device is successfully transmitted. After the first A-IoT terminal device sends the uplink data, the A-IoT network device can synchronize the reception status of the uplink data to the first A-IoT terminal device by sending the first information. At this time, there is a corresponding relationship between the bit position of the first signaling and the sub-channel, and the first A-IoT terminal device is the A-IoT terminal device corresponding to the sub-channel. For example, when the A-IoT network device successfully receives the data of the A-IoT terminal device of the first sub-channel, the value of the bit position corresponding to the first sub-channel in the first signaling is 1, otherwise, it is 0. Alternatively, when the A-IoT network device successfully receives the data of the A-IoT terminal device of the first sub-channel, the value of the bit position corresponding to the first sub-channel in the first signaling is 0, otherwise, it is 1.

The second information is used to indicate whether the uplink data of the A-IoT terminal device in the sub-channel group where the first A-IoT terminal device is located is successfully transmitted. After the A-IoT terminal device in the sub-channel group where the first A-IoT terminal device is located sends the uplink data, the A-IoT network device can synchronize the reception status of the uplink data to the A-IoT terminal devices in the sub-channel group where the first A-IoT terminal device is located by sending the first information. At this time, there is a corresponding relationship between the bit positions of the first signaling and the sub-channel groups. For example, when the A-IoT network device successfully receives the data of the A-IoT terminal device in the first sub-channel group, the value of the bit position corresponding to the first sub-channel group in the first signaling is 1, otherwise, it is 0. Alternatively, when the A-IoT network device successfully receives the data of the A-IoT terminal device in the first sub-channel group, the value of the bit position corresponding to the first sub-channel group in the first signaling is 0, otherwise, it is 1.

For example, the first sub-channel group includes at least two A-IoT terminal devices. When the A-IoT network device receives uplink data sent by at least one A-IoT terminal device in the first sub-channel group, it can be considered that the A-IoT network device has successfully received the data of the A-IoT terminal device in the first sub-channel group; or, preferably, when the A-IoT network device receives uplink data sent by all A-IoT terminal devices in the first sub-channel group, it can be considered that the A-IoT network device has successfully received the data of the A-IoT terminal devices in the first sub-channel group.

The third information is used to indicate whether the first A-IoT terminal device retransmits. For example, when the first A-IoT terminal device fails to transmit uplink data, the A-IoT network device can instruct the first A-IoT terminal device to retransmit according to the third information. For example, when the A-IoT network device indicates that the A-IoT terminal device of the first subchannel needs to retransmit, the value of the bit corresponding to the first subchannel in the first signaling is 1, otherwise, it is 0. Alternatively, when the A-IoT network device indicates that the A-IoT terminal device of the first subchannel needs to retransmit, the value of the bit corresponding to the first subchannel in the first signaling is 0, otherwise, it is 1.

The fourth information is used to indicate whether the A-IoT terminal device in the sub-channel group where the first A-IoT terminal device is located retransmits. For example, when the A-IoT terminal device in the first sub-channel group fails to transmit uplink data, the A-IoT network device can instruct the A-IoT terminal device to retransmit according to the third information. For example, when the A-IoT network device indicates that the A-IoT terminal device in the first sub-channel group needs to retransmit, the value of the bit corresponding to the first sub-channel group in the first signaling is 1, otherwise, it is 0. Alternatively, when the A-IoT network device indicates that the A-IoT terminal device in the first sub-channel group needs to retransmit, the value of the bit corresponding to the first sub-channel group in the first signaling is 0, otherwise, it is 1.

The fifth information is used to indicate whether the first A-IoT terminal device modifies the scheduling sequence number. For example, when the first A-IoT terminal device needs to be rescheduled, the scheduling sequence number of the first A-IoT terminal device can be modified in order to reduce latency. For example, when the A-IoT network device indicates that the A-IoT terminal device of the first sub-channel needs to modify the scheduling sequence number, the value of the bit corresponding to the first sub-channel in the first signaling is 1, otherwise, it is 0. Alternatively, when the A-IoT network device indicates that the A-IoT terminal device of the first sub-channel needs to modify the scheduling sequence number, the value of the bit corresponding to the first sub-channel in the first signaling is 0, otherwise, it is 1.

The sixth information is used to indicate whether the A-IoT terminal device in the sub-channel group where the first A-IoT terminal device is located has modified the scheduling sequence number. For example, when the A-IoT terminal device in the first sub-channel group needs to be re-scheduled, in order to reduce latency, the scheduling sequence number of the A-IoT terminal device in the first sub-channel group can be modified. For example, when the A-IoT network device indicates that the A-IoT terminal device in the first sub-channel group needs to modify the scheduling sequence number, the value of the bit corresponding to the first sub-channel group in the first signaling is 1, otherwise, it is 0. Alternatively, when the A-IoT network device indicates that the A-IoT terminal device in the first sub-channel group needs to modify the scheduling sequence number, the value of the bit corresponding to the first sub-channel group in the first signaling is 0, otherwise, it is 1.

The seventh information is used to indicate the way in which the A-IoT terminal device of the first A-IoT terminal device modifies the scheduling sequence number.

The eighth information is used to indicate how the A-IoT terminal device in the sub-channel group where the first A-IoT terminal device is located modifies the scheduling sequence number.

Step 2102: The first A-IoT terminal device adjusts the scheduling sequence number of the first A-IoT terminal device based on the first signaling.

In some embodiments, the first A-IoT terminal device can determine the manner in which the A-IoT terminal device adjusts the scheduling sequence number based on the seventh or eighth information in the first signaling.

In some embodiments, when the first signaling indicates at least one of the following situations, the scheduling sequence number of the first A-IoT terminal device may be adjusted:

The first signaling indicates that the transmission of the first A-IoT terminal device is unsuccessful or failed;

The first signaling indicates that the first A-IoT terminal device needs to retransmit;

The first signaling indicates that the first A-IoT terminal device needs to modify the scheduling sequence number;

The first signaling indicates that the transmission of the A-IoT terminal device of its sub-channel group is unsuccessful or failed;

The first signaling indicates that the A-IoT terminal device corresponding to its sub-channel group needs to retransmit;

The first signaling indicates that the A-IoT terminal device corresponding to its sub-channel group needs to modify the scheduling sequence number.

In some embodiments, this step is an optional step. When the first signaling indication does not satisfy the above conditions, the scheduling number of the first A-IoT terminal device may not be adjusted, that is, the scheduling number is maintained unchanged.

In some embodiments, the scheduling sequence number of the first A-IoT terminal device may be accumulated by i, where i is a positive integer. That is, the A-IoT terminal device may accumulate its own scheduling sequence number, that is, add i to the original scheduling sequence number, and preferably, i may be 1.

In some embodiments, the scheduling sequence number of the first A-IoT terminal device can be randomly adjusted, that is, the scheduling sequence number of the first A-IoT terminal device can be randomly changed.

In some embodiments, the scheduling sequence number of the first A-IoT terminal device can be accumulated by k, where k is the total number of A-IoT terminal devices in the sub-channel group where the first A-IoT terminal device is located. That is, the scheduling sequence number of the first A-IoT terminal device can be placed at the last one in the sub-channel group and scheduled at the end.

Step 2103: The A-IoT network device sends a second signaling to the first A-IoT terminal device.

In some embodiments, under a first condition, the A-IoT network device may send a second signaling to the first A-IoT terminal device.

In some embodiments, the second signaling can be used to instruct the first A-IoT terminal device to be discarded or locked.

In some embodiments, the name of the second signaling may be “failure instruction”, “discard instruction”, etc., which is not limited in the present disclosure.

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

The first A-IoT terminal device fails to successfully establish communication with the A-IoT network device. For example, the A-IoT network device schedules the first A-IoT terminal device, but fails to receive or correctly decodes valid feedback from the first A-IoT terminal device, that is, this round of scheduling fails;

During the first time interval, the A-IoT network device fails to successfully schedule the first A-IoT terminal device;

The A-IoT network device fails to successfully schedule the first A-IoT terminal device J times, where J is a positive integer, i.e., when the A-IoT network device schedules the first A-IoT terminal device J times and fails to receive feedback from the first A-IoT terminal device J times, the scheduling fails.

During the first time interval, the A-IoT network device fails to successfully receive or fails to successfully decode uplink data sent by the first A-IoT terminal device;

The A-IoT network device fails to successfully receive or fails to successfully decode J uplink data sent by the first A-IoT terminal device, where J is a positive integer.

In some embodiments, the first time interval may be predefined by a protocol, or may be dynamically determined by the A-IoT network device according to a network status.

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, when the second signaling indicates discarding or locking the first A-IoT terminal device, the specific operation of the first A-IoT terminal device may include at least one of the following:

Instruct the first A-IoT terminal device to stop sending uplink data or stop receiving downlink signaling, that is, the first A-IoT terminal device no longer communicates with the A-IoT network device;

Deleting the first A-IoT terminal device from the first scheduling group, that is, the A-IoT network device can clear the information of the first A-IoT terminal device, and when the first A-IoT terminal device is retrieved, the first A-IoT terminal device can be reconnected to the network as a new device;

Setting the scheduling sequence number of the first A-IoT terminal device to invalid or the maximum value, that is, invalidating the first A-IoT terminal device and no longer responding to the instruction information sent by the A-IoT network device;

The bit position of the sub-channel or sub-channel group where the first A-IoT terminal device is located is set to invalid or maximum value, that is, the bit position of the sub-channel or sub-channel group where the first A-IoT terminal device is located is invalidated. At this time, the first A-IoT terminal device no longer responds to the indication information sent by the A-IoT network device.

In some embodiments, this step is an optional step. When the first condition is not met, the A-IoT network device may not send the second signaling. The positioning measurement method involved in the embodiment of the present disclosure may include at least one of steps 2101 to 2103.

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 dynamic scheduling of A-IoT devices.

An important application of A-IoT technology is to inventory and monitor large-scale items/materials. In order to meet the requirements of actual applications, in addition to being able to process massive amounts of communication data, communication between A-IoT devices must also ensure high reliability of communication and reduce inventory latency, which are potential design goals for A-IoT devices. In the actual scheduling process, A-IoT terminal devices are not always able to complete scheduling in the first transmission, and may need to be scheduled twice or even multiple times. When an A-IoT terminal device needs to be rescheduled, if its scheduling group or scheduling sequence number is not changed, it needs to complete a cycle before it can be rescheduled, which will lead to more serious latency problems. In order to solve the above problems, this example designs a scheduling method for A-IoT terminal devices based on dynamic scheduling sequence numbers. By dynamically changing the scheduling sequence number of the A-IoT terminal device, the next scheduling can be flexibly arranged for the A-IoT terminal device that failed to be successfully scheduled.

In a network, A-IoT network devices can communicate with A-IoT terminal devices. A-IoT network devices may include base stations, terminals, intermediate nodes, auxiliary nodes, etc. The types of A-IoT terminal devices 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. The excitation signal can be used to trigger the communication of the A-IoT terminal device, transmit control signaling, data, etc. Optionally, the excitation signal can also be used to charge the A-IoT terminal device. The A-IoT terminal devices are divided into at least one group. The A-IoT network device schedules at least one scheduling group in one scheduling. Preferably, one scheduling group can be scheduled at one time. Information exchange is performed between the A-IoT network device and the A-IoT terminal device.

After the A-IoT network device receives the data from the A-IoT terminal device, the A-IoT network device sends a feedback indication signaling to the A-IoT terminal device. The method for determining the feedback indication signaling may include at least one of the following:

The data structure of the feedback indication signaling may be predefined by the protocol. The feedback indication signaling consists of a bitmap, the size of the bitmap (i.e., size N) may be greater than or equal to the number of subchannels, and the value set of N may be a subset of natural numbers. A subchannel corresponds to a bit in a bitmap, and preferably, a subchannel corresponds to a bit in a bitmap one by one.

In some embodiments, the first high bit in the bitmap may correspond to the first subchannel, the second high bit in the bitmap may correspond to the second subchannel, and so on until all subchannels correspond to bits in the bitmap. Alternatively, the first low bit in the bitmap may correspond to the first subchannel, the second low bit in the bitmap may correspond to the second subchannel, and so on until all subchannels correspond to bits in the bitmap.

The functions of the feedback indication signaling may include at least one of the following:

In some embodiments, the feedback indication signaling can be used to indicate whether the uplink data transmission of the A-IoT terminal device is successful. When the A-IoT network device successfully receives the data of the A-IoT terminal device of the first sub-channel, the bit corresponding to the sub-channel can be 1, otherwise, it is 0. Alternatively, when the A-IoT network device successfully receives the data of the A-IoT terminal device of the first sub-channel, the bit corresponding to the sub-channel can be 0, otherwise, it is 1.

In some embodiments, the feedback indication signaling can be used to indicate whether the A-IoT terminal device needs to retransmit. If the A-IoT network device indicates that the A-IoT terminal device of the first subchannel needs to retransmit, the bit corresponding to the subchannel is 1, otherwise, it is 0. Alternatively, if the A-IoT network device indicates that the A-IoT terminal device of the first subchannel needs to retransmit, the bit corresponding to the subchannel is 0, otherwise, it is 1.

In some embodiments, the feedback indication signaling can be used to indicate whether the A-IoT terminal device needs to modify the scheduling sequence number. If the A-IoT network device indicates that the A-IoT terminal device of the first subchannel needs to modify the scheduling sequence number, the bit corresponding to the subchannel is 1, otherwise, it is 0. Alternatively, if the A-IoT network device indicates that the A-IoT terminal device of the first subchannel needs to modify the scheduling sequence number, the bit corresponding to the subchannel is 0, otherwise, it is 1.

Example 2

The data structure of the feedback indication signaling can be predefined by the protocol. The feedback indication signaling consists of a bitmap, and the size N of the bitmap is greater than or equal to the number of sub-channels. The value set of N is a subset of natural numbers. At least m subchannels correspond to bits in a bitmap, where m is not greater than M and is at least 2. The M subchannels are divided into sub-channel groups.

In some embodiments, the first high bit in the bitmap corresponds to the first sub-channel group, the second high bit in the bitmap corresponds to the second sub-channel group, and so on until all sub-channel groups correspond to bits in the bitmap. Alternatively, further, the first low bit in the bitmap corresponds to the first sub-channel group, the second low bit in the bitmap corresponds to the second sub-channel group, and so on until all sub-channel groups correspond to bits in the bitmap.

The functions of the feedback indication signaling may include at least one of the following:

In some embodiments, feedback indication signaling can be used to indicate whether uplink data transmission of the A-IoT terminal device corresponding to the sub-channel group is successful. If the A-IoT network device successfully receives data from the A-IoT terminal device of the first sub-channel group, the bit corresponding to the sub-channel group is 1, otherwise, it is 0. Alternatively, if the A-IoT network device successfully receives data from the A-IoT terminal device of the first sub-channel group, the bit corresponding to the sub-channel group is 0, otherwise, it is 1.

In some embodiments, the feedback indication signaling can be used to indicate whether the A-IoT terminal device corresponding to the sub-channel group needs to retransmit. If the A-IoT network device indicates that the A-IoT terminal device of the first sub-channel group needs to retransmit, the bit corresponding to the sub-channel group is 1, otherwise, it is 0. Alternatively, if the A-IoT network device indicates that the A-IoT terminal device of the first sub-channel group needs to retransmit, the bit corresponding to the sub-channel production group is 0, otherwise, it is 1.

In some embodiments, the feedback indication signaling can be used to indicate whether the A-IoT terminal device corresponding to the sub-channel group needs to modify the scheduling sequence number. If the A-IoT network device indicates that the A-IoT terminal device of the first sub-channel group needs to modify the scheduling sequence number, the bit corresponding to the sub-channel group is 1, otherwise, it is 0. Alternatively, if the A-IoT network device indicates that the A-IoT terminal device of the first sub-channel group needs to modify the scheduling sequence number, the bit corresponding to the sub-channel is 0, otherwise, it is 1.

Optionally, subchannels with adjacent sequence numbers may be continuous or discontinuous in the frequency domain.

Optionally, the sub-channel coding may be from low frequency to high frequency, from small to large, or from large to small. Alternatively, the sub-channel coding may be from high frequency to low frequency, from small to large, or from large to small.

After receiving the above feedback indication signaling, the A-IoT terminal device will adjust the scheduling sequence number accordingly. The method for determining the adjusted scheduling sequence number includes at least one of the following:

The A-IoT terminal device accumulates its own scheduling sequence number, that is, adds i to the original scheduling sequence number, where i is an integer, preferably 1.

Otherwise, keep the scheduling sequence number unchanged.

As shown in Figure 6, the A-IoT network device initiates scheduling to the A-IoT terminal devices of the three sub-channel groups in the order of scheduling groups 1, 2, 3, 4, etc. In the first scheduling in the above figure, Tag2-1 failed to be transmitted successfully, so the A-IoT network device sends a feedback indication 101, and after the sub-channel group receives the Tag, the scheduling sequence number is increased by 1.

Otherwise, keep the scheduling sequence number unchanged.

When the A-IoT network device fails to successfully establish communication with the A-IoT terminal device, the A-IoT terminal device needs to be discarded or locked. The corresponding method includes at least one of the following:
