Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0104] A-IoT is a new IoT technology. Compared to traditional IoT technologies, a notable feature is the large number of A-IoT terminals (A-IoT UEs, also known as A-IoT devices or A-IoT tags) in the network, enabling large-scale inventory and monitoring of items. Compared to NB-IoT terminals, A-IoT terminals have a simpler structure, lower hardware and maintenance costs, and can be equipped with or without a power supply. Currently, A-IoT devices can be categorized into three types: Type A, Type B, and Type C. Type A devices do not support energy storage and primarily operate based on backscatter, exhibiting the lowest complexity and consuming very little power. Although Type A devices do not support energy storage, they still need to receive wireless signals to activate their internal receive processing modules. Type B devices support energy storage and operate based on backscatter. Their complexity and power consumption are higher than those of Type A devices, but remain relatively low. Type B devices can store energy, but their storage capacity is generally limited. Device type C supports energy storage and works based on active transmission, that is, the device type C can amplify and transmit information through a power amplifier.

[0105] A-IoT technology is applicable to various production and daily life scenarios, including smart logistics, smart warehousing, and factory automation. These production scenarios share a common characteristic: the variety and quantity of materials or items are complex. In these scenarios, inventorying of materials or items within the network is a key application of A-IoT technology. Compared to traditional NR communications, inventory communication for massive devices is more centralized and regular. More centralized means that when a user triggers an inventory, all devices in a cell must provide feedback within a certain timeframe. More regular means that if the network needs to periodically monitor the status of items or materials attached to a device, regular inventory triggering is necessary. Device inventories can be triggered either periodically or instantly. Periodic triggering is used to periodically monitor the status of materials or items attached to a device, helping users obtain reference information for coordinated planning. For device type A or type B, periodic triggering relies on the radio equipment for periodic control due to its limited power supply. For device type C, a trigger period can be configured, allowing device type C to periodically report information. Immediate triggering, or aperiodic triggering, is identical to periodic triggering for device type A or type B, implemented by the base station. However, for device type C, it may involve scheduling similar to paging.

[0106] In existing technologies, A-IoT networking modes mainly include the following: a direct connection between a base station and an A-IoT device, allowing both parties to communicate uplink and downlink; a connection between a base station and an intermediate node, allowing both parties to communicate uplink and downlink, and a connection between the intermediate node and the A-IoT device, allowing both parties to communicate uplink and downlink. Furthermore, the base station and the A-IoT device cannot communicate via uplink or downlink; a connection between a base station and an A-IoT device via an auxiliary node, allowing both parties to communicate downlink, and a connection between the base station and the A-IoT device, allowing both parties to communicate uplink and downlink; and a connection between a terminal and an A-IoT device, allowing both parties to communicate uplink and downlink, meaning that the terminal can replace the base station in connecting to the A-IoT device.

[0107] The communication process between A-IoT devices is as follows: An A-IoT network device sends downlink signaling on a downlink channel to trigger communication with an A-IoT device. For device type A or device type B, each device group (each group contains at least one device) can reflect the signal to a different sub-channel. For device type C, each device group can be configured with a different sub-channel. Communication between different devices on different sub-channels can avoid interference between adjacent sub-channels through network deployment and network device configuration. For example, a base station (BS), a UE terminal, an intermediate node, or an auxiliary node (Xnote) can send downlink signaling (DL) to simultaneously trigger devices 1, 2, and 3. These three devices then perform uplink transmissions on sub-uplink channels 1, 2, and 3, respectively. The specific communication process is shown in Figure 7.

[0108] When A-IoT technology is applied to inventory and monitoring large quantities of items or materials, there are many A-IoT devices. Communication between these devices must be able to handle massive amounts of data. Furthermore, ensuring high reliability and reducing inventory latency are potential design goals for A-IoT devices. However, in actual scheduling, A-IoT terminal devices are not always able to complete scheduling on 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 will take a full cycle before it can be rescheduled, resulting in significant latency.

[0109] To address the above issues, 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, it is possible to flexibly arrange the next scheduling for A-IoT terminal devices that failed to be successfully scheduled, thereby reducing latency. The specific contents of this solution are as follows.

[0110] Figure 2 is an interactive diagram of a communication method based on the ambient Internet of Things according to an embodiment of the present disclosure. As shown in Figure 2, 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:

[0111] Step 2101: The A-IoT network device sends a first signaling to a first A-IoT terminal device.

[0112] 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.

[0113] 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.

[0114] In some embodiments, a first A-IoT terminal device belongs to a first scheduling group, and multiple A-IoT terminal devices in the first scheduling group have at least one identical scheduling sequence number. That is, the A-IoT terminal devices can be grouped based on the scheduling sequence number, with the A-IoT terminal devices having at least one identical scheduling sequence number grouped together.

[0115] 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.

[0116] 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.

[0117] In the above embodiment, the bits of the first signaling may correspond to the subchannels, and the correspondence may be that one subchannel corresponds to a bit in the bitmap of the first signaling. Preferably, the subchannels and the bits in the bitmap may correspond one to one. For example, the first high-order bit in the bitmap may correspond to the first subchannel, the second high-order bit in the bitmap may correspond to the second subchannel, and so on until all subchannels correspond to bits in the bitmap. Alternatively, further, the first low-order bit in the bitmap may correspond to the first subchannel, the second low-order bit in the bitmap may correspond to the second subchannel, and so on until all subchannels correspond to bits in the bitmap.

[0118] In other words, each bit in the bitmap of the first signaling may correspond one-to-one to a sub-channel in ascending or descending order.

[0119] In some embodiments, bits of the first signaling may correspond to sub-channel groups. The correspondence may be one sub-channel group corresponding to a bit in a bitmap of the first signaling. For example, the first high-order bit in the bitmap corresponds to the first sub-channel group, the second high-order bit in the bitmap corresponds to the second sub-channel group, and so on until all sub-channel groups have a correspondence with bits in the bitmap. Alternatively, the first low-order bit in the bitmap corresponds to the first sub-channel group, the second low-order bit in the bitmap corresponds to the second sub-channel group, and so on until all sub-channel groups have a correspondence with bits in the bitmap.

[0120] 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.

[0121] In some embodiments, the dynamic scheduling information may include at least one of the following first to eighth information.

[0122] 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.

[0123] 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 device 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 of the first signaling and the sub-channel group. 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 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 corresponding to the first sub-channel group in the first signaling is 0, otherwise, it is 1.

[0124] 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 device in the first sub-channel group.

[0125] The third information is used to indicate whether the first A-IoT terminal device should retransmit. 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 sub-channel needs to retransmit, 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 retransmit, the value of the bit corresponding to the first sub-channel in the first signaling is 0, otherwise, it is 1.

[0126] 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 instructs the A-IoT terminal device in the first sub-channel group that retransmits, 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 instructs the A-IoT terminal device in the first sub-channel group that retransmits, the value of the bit corresponding to the first sub-channel group in the first signaling is 0, otherwise, it is 1.

[0127] 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 re-scheduled, the scheduling sequence number of the first A-IoT terminal device can be modified in order to reduce the 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.

[0128] 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 the 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.

[0129] The seventh information is used to indicate how the A-IoT terminal device of the first A-IoT terminal device modifies the scheduling sequence number.

[0130] 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.

[0131] In 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.

[0132] 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.

[0133] 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:

[0134] The first signaling indicates that the transmission of the first A-IoT terminal device is unsuccessful or failed;

[0135] The first signaling indicates that the first A-IoT terminal device needs to retransmit;

[0136] The first signaling indicates that the first A-IoT terminal device needs to modify the scheduling sequence number;

[0137] The first signaling indicates that the transmission of the A-IoT terminal device in its sub-channel group is unsuccessful or failed;

[0138] The first signaling indicates that the A-IoT terminal device corresponding to its sub-channel group needs to retransmit;

[0139] The first signaling indicates that the A-IoT terminal device corresponding to its sub-channel group needs to modify the scheduling sequence number.

[0140] In some embodiments, this step is an optional step. When the first signaling indication does not satisfy the above conditions, the scheduling sequence number of the first A-IoT terminal device may not be adjusted, that is, the scheduling sequence number is maintained unchanged.

[0141] 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, i.e., add i to the original scheduling sequence number. Preferably, i may be 1.

[0142] 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.

[0143] 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.

[0144] Step 2103: The A-IoT network device sends a second signaling to the first A-IoT terminal device.

[0145] In some embodiments, under the first condition, the A-IoT network device may send a second signaling to the first A-IoT terminal device.

[0146] In some embodiments, the second signaling can be used to instruct the first A-IoT terminal device to be discarded or locked.

[0147] In some embodiments, the name of the second signaling may be "invalidation instruction", "discard instruction", etc., which is not limited in the present disclosure.

[0148] In some embodiments, the first condition may include at least one of the following:

[0149] 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 decode valid feedback from the first A-IoT terminal device, indicating that this round of scheduling has failed.

[0150] During the first time interval, the A-IoT network device fails to successfully schedule the first A-IoT terminal device;

[0151] The A-IoT network device fails to successfully schedule the first A-IoT terminal device J times, where J is a positive integer. That is, if the A-IoT network device schedules the first A-IoT terminal device J times and does not receive any feedback from the first A-IoT terminal device J times, then the scheduling is considered unsuccessful.

[0152] 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;

[0153] The A-IoT network device fails to successfully receive or fails to successfully decode the J uplink data sent by the first A-IoT terminal device, where J is a positive integer.

[0154] 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.

[0155] In some embodiments, the measurement unit of the first time interval may be an absolute time unit or a relative time unit.

[0156] 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.

[0157] Relative time units include but are not limited to: time domain symbols, time slots, radio subframes, radio frames, radio half frames, etc.

[0158] 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:

[0159] 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;

[0160] Deleting the first A-IoT terminal device from the first scheduling group, that is, the A-IoT network device may 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 may be re-connected to the network as a new device;

[0161] 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 so that it no longer responds to the instruction information sent by the A-IoT network device;

[0162] 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.

[0163] In some embodiments, this step is optional. 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. For example, step 2101 can be implemented as an independent embodiment, steps 2101+2102+2103 can be implemented as an independent embodiment, steps 2101+2103 can be implemented as an independent embodiment, and steps 2101+2102 can be implemented as an independent embodiment, but are not limited thereto.

[0210] The following is an exemplary introduction to the above method.

[0211] The method shown in the embodiments of the present disclosure relates to a system and method suitable for dynamic scheduling of A-IoT devices.

[0212] A key application of A-IoT technology is the inventory and monitoring of large quantities of items and materials. To meet these requirements, communication between A-IoT devices must not only be able to handle massive amounts of data, but also ensure high reliability and minimize inventory latency. These are potential design goals for A-IoT devices. In actual scheduling, A-IoT devices do not always complete scheduling on the first transmission, potentially requiring secondary or even multiple scheduling attempts. If an A-IoT device needs to be rescheduled, without changing its scheduling group or sequence number, it will take a full cycle before it can be rescheduled, resulting in significant latency. To address this issue, this example designs a scheduling method for A-IoT devices based on dynamic scheduling sequences. By dynamically changing the scheduling sequence numbers of A-IoT devices, unscheduled A-IoT devices can be flexibly scheduled for the next time.

[0213] 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., and 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 communication with the A-IoT terminal device and 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. In a single scheduling, the A-IoT network device schedules at least one scheduling group, and preferably, one scheduling group at a time. The A-IoT network device and the A-IoT terminal device exchange information.

[0214] After the A-IoT network device receives 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:

[0215] Example 1

[0216] The data structure of the feedback indication signaling can be predefined by the protocol. The feedback indication signaling consists of a bitmap. The size of the bitmap (i.e., size N) can be greater than or equal to the number of subchannels, and the set of values ​​for N can be a subset of natural numbers. A subchannel corresponds to a bit in the bitmap. Preferably, there is a one-to-one correspondence between subchannels and bits in the bitmap.

[0217] In some embodiments, the first high-order bit in the bitmap may correspond to the first subchannel, the second high-order 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-order bit in the bitmap may correspond to the first subchannel, the second low-order bit in the bitmap may correspond to the second subchannel, and so on until all subchannels correspond to bits in the bitmap.

[0218] The functions of the feedback indication signaling may include at least one of the following:

[0219] In some embodiments, feedback indication signaling can be used to indicate whether uplink data transmission from an A-IoT terminal device is successful. When the A-IoT network device successfully receives data from an A-IoT terminal device on a first subchannel, the bit corresponding to that subchannel may be 1; otherwise, it may be 0. Alternatively, when the A-IoT network device successfully receives data from an A-IoT terminal device on a first subchannel, the bit corresponding to that subchannel may be 0; otherwise, it may be 1.

[0220] In some embodiments, 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 on the first subchannel needs to retransmit, the bit corresponding to that subchannel is 1; otherwise, it is 0. Alternatively, if the A-IoT network device indicates that the A-IoT terminal device on the first subchannel needs to retransmit, the bit corresponding to that subchannel is 0; otherwise, it is 1.

[0221] In some embodiments, feedback indication signaling can be used to indicate whether the A-IoT terminal device needs to modify its scheduling sequence number. If the A-IoT network device indicates that the A-IoT terminal device on the first subchannel needs to modify its scheduling sequence number, the bit corresponding to that subchannel is 1; otherwise, it is 0. Alternatively, if the A-IoT network device indicates that the A-IoT terminal device on the first subchannel needs to modify its scheduling sequence number, the bit corresponding to that subchannel is 0; otherwise, it is 1.

[0222] Example 2

[0223] 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.

[0224] In some embodiments, the first high-order bit in the bitmap corresponds to the first sub-channel group, the second high-order 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, the first low-order bit in the bitmap corresponds to the first sub-channel group, the second low-order 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.

[0225] The functions of the feedback indication signaling may include at least one of the following:

[0226] In some embodiments, feedback indication signaling can be used to indicate whether uplink data transmission of the A-IoT terminal device corresponding to a sub-channel group is successful. If the A-IoT network device successfully receives data from the A-IoT terminal device in the first sub-channel group, the bit corresponding to that 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 in the first sub-channel group, the bit corresponding to that sub-channel group is 0; otherwise, it is 1.

[0227] In some embodiments, feedback indication signaling can be used to indicate whether the A-IoT terminal device corresponding to a sub-channel group requires retransmission. If the A-IoT network device indicates that the A-IoT terminal device in the first sub-channel group requires retransmission, the bit corresponding to that sub-channel group is set to 1; otherwise, it is set to 0. Alternatively, if the A-IoT network device indicates that the A-IoT terminal device in the first sub-channel group requires retransmission, the bit corresponding to that sub-channel group is set to 0; otherwise, it is set to 1.

[0228] In some embodiments, feedback indication signaling can be used to indicate whether the A-IoT terminal device corresponding to a sub-channel group needs to modify its scheduling sequence number. If the A-IoT network device indicates that the A-IoT terminal device in the first sub-channel group needs to modify its scheduling sequence number, the bit corresponding to that sub-channel group is set to 1; otherwise, it is set to 0. Alternatively, if the A-IoT network device indicates that the A-IoT terminal device in the first sub-channel group needs to modify its scheduling sequence number, the bit corresponding to that sub-channel is set to 0; otherwise, it is set to 1.

[0229] Optionally, subchannels with adjacent sequence numbers may be continuous or discontinuous in the frequency domain.

[0230] 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.

[0231] 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:

[0232] Example 1

[0233] When the A-IoT terminal device receives feedback indication signaling indicating at least one of the following situations:

[0234] Feedback indication signaling indicates that the A-IoT terminal device transmission was unsuccessful or failed;

[0235] Feedback indication signaling indicates that the A-IoT terminal device needs to retransmit;

[0236] Feedback indication signaling indicates that the A-IoT terminal device needs to modify the scheduling sequence number;

[0237] Feedback indication signaling indicates that the A-IoT terminal device in its sub-channel group has failed or failed in transmission;

[0238] The feedback indication signaling indicates that the A-IoT terminal device corresponding to its sub-channel group needs to retransmit;

[0239] The feedback indication signaling indicates that the A-IoT terminal device corresponding to its sub-channel group needs to modify the scheduling sequence number.

[0240] 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.

[0241] Otherwise, keep the scheduling sequence number unchanged.

[0242] As shown in Figure 6, the A-IoT network device initiates scheduling to the A-IoT terminal devices in the three sub-channel groups, following the order of scheduling groups 1, 2, 3, and 4. In the first scheduling in the figure above, Tag 2-1 fails to transmit successfully, so the A-IoT network device sends a feedback indication 101. After receiving the sub-channel group's tag, the scheduling sequence number is incremented by 1.

[0243] Example 2

[0244] When the A-IoT terminal device receives feedback indication signaling indicating at least one of the following situations:

[0245] Feedback indication signaling indicates that the A-IoT terminal device transmission was unsuccessful or failed;

[0246] Feedback indication signaling indicates that the A-IoT terminal device needs to retransmit;

[0247] Feedback indication signaling indicates that the A-IoT terminal device needs to modify the scheduling sequence number;

[0248] Feedback indication signaling indicates that the A-IoT terminal device in its sub-channel group has failed or failed in transmission;

[0249] The feedback indication signaling indicates that the A-IoT terminal device corresponding to its sub-channel group needs to retransmit;

[0250] The feedback indication signaling indicates that the A-IoT terminal device corresponding to its sub-channel group needs to modify the scheduling sequence number.

[0251] The A-IoT terminal device will randomly change its own scheduling sequence number.

[0252] Otherwise, keep the scheduling sequence number unchanged.

[0253] Example 3

[0254] When the A-IoT terminal device receives feedback indication signaling indicating at least one of the following situations:

[0255] Feedback indication signaling indicates that the A-IoT terminal device transmission was unsuccessful or failed;

[0256] Feedback indication signaling indicates that the A-IoT terminal device needs to retransmit;

[0257] Feedback indication signaling indicates that the A-IoT terminal device needs to modify the scheduling sequence number;

[0258] Feedback indication signaling indicates that the A-IoT terminal device in its sub-channel group has failed or failed in transmission;

[0259] The feedback indication signaling indicates that the A-IoT terminal device corresponding to its sub-channel group needs to retransmit;

[0260] The feedback indication signaling indicates that the A-IoT terminal device corresponding to its sub-channel group needs to modify the scheduling sequence number.

[0261] The A-IoT terminal device places its own scheduling sequence number at the last one in the sub-channel group, that is, based on the current scheduling sequence number + K, where K is the total number of A-IoT terminal devices in the current sub-channel group.

[0262] Otherwise, keep the scheduling sequence number unchanged.

[0263] 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 methods include at least one of the following:

[0264] Example 1

[0265] If scheduling fails for the same A-IoT terminal device on the same subchannel J times in a first time interval, the A-IoT terminal device is discarded or a lock or kill command is sent to the device. The first time interval is predefined and confirmed by the protocol, and the measurement unit of the first time interval can be absolute time units or relative time units. J is predefined by the protocol, and its value set is a subset of positive integers.

[0266] Example 2

[0267] If the same A-IoT terminal device on the same subchannel fails to be scheduled J times in a row, the A-IoT terminal device is discarded or a lock or kill command is sent to the device. J is predefined by the protocol and its value set is a subset of positive integers.

[0268] Example 3

[0269] If scheduling fails for the same A-IoT terminal device on the same subchannel within the first time interval, the A-IoT terminal device is discarded or a lock or kill instruction is sent to the device. J is predefined by the protocol and its value set is a subset of positive integers.

[0270] In summary, in the above-mentioned embodiments of the present solution, the A-IoT network device sends feedback indication signaling to the A-IoT terminal device, which can indicate the status of the uplink transmission of the A-IoT terminal device, or can instruct the A-IoT terminal device to perform temporary scheduling. The A-IoT network device can define the adjustment rules of the scheduling sequence number and process the terminal when the A-IoT terminal device is lost to avoid waste of resources. It can realize dynamic scheduling of the A-IoT terminal device, improve the flexibility of scheduling, and reduce latency.
