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 UE, 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 lack energy storage, they still need to receive wireless signals to activate their internal receive and 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. 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 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 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 frequency device 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.

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.

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 group of devices (each group contains at least one device) can reflect the signal to a different sub-channel. For device type C, each group of devices can be configured to correspond to 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 user equipment 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.

In existing New Radio (NR) mechanisms, repetition is a common method for enhancing coverage. Conventional thinking allows for retransmissions to be configured by configuring a repetition factor, which can be either semi-static or dynamic. Dynamic indication increases signaling overhead, and for A-IoT devices, semi-static resources for Type A and Type B devices are difficult to locate due to difficulties with time-frequency synchronization and the risk of power outages. Therefore, a simpler and more practical repetition approach can be considered.

In response to the above problems, the present disclosure proposes a communication method based on the ambient Internet of Things (A-IoT). This method can achieve repeated transmission of A-IoT devices through static configuration or the introduction of a termination mechanism.

The above static configuration, i.e. one-time configuration, means that all transmissions are repeated. It can also be subdivided into repetitions for specific instructions or specific services. The termination mechanism means that after the A-IoT network device is triggered, the A-IoT terminal device continues to send, without limit, before it indicates termination. Another termination mechanism is that after the A-IoT network device is triggered, the A-IoT terminal device continues to send within a certain time domain. The method can be sent without limiting the number of times, which, to a certain extent, weakens the concepts of time slot and PUSCH. The details of this method are as follows.

Figure 2 is an interactive diagram illustrating a communication method based on the A-IoT according to an embodiment of the present disclosure. As shown in Figure 2, the present disclosure embodiment relates to a communication method based on the A-IoT, which is used in a communication system 100. The communication system 100 may include an A-IoT network device 101 and an A-IoT terminal device 102. The method includes:

Step 2101: The A-IOT network device sends a first signaling to the A-IOT terminal device.

In some embodiments, the first signaling may be used to instruct the A-IOT terminal device about repeated transmission information.

In some embodiments, the first signaling may be used for the first service, and the first signaling includes at least one of the following:

The first information is used to indicate whether the A-IOT terminal device repeatedly sends the first service;

The second information is used to indicate the number of times the A-IOT terminal device repeatedly sends the first service.

In some embodiments, when the first signaling is used for the first service, the protocol may predefine a repeat indication field, and the first signaling is included in the repeat indication field.

In some embodiments, the type of the first signaling may be dynamic, semi-static, or static.

In some embodiments, the first signaling may also be used for a first object, where the first object includes one or more second signalings and/or one or more second services, and the first signaling includes at least one of the following:

The third information is used to indicate whether the A-IOT terminal device repeatedly sends the first object;

The fourth information is used to indicate the number of times the A-IOT terminal device repeatedly sends the first object;

The fifth information is used to indicate whether the A-IOT terminal device repeats the second signaling;

The sixth information is used to indicate the number of times the A-IOT terminal device repeatedly sends the second signaling;

The seventh information is used to indicate whether the A-IOT terminal device repeats the transmission for the second service;

The eighth information is used to indicate the number of times the A-IOT terminal device repeatedly sends the second service.

In some embodiments, when the first signaling is used for the first object, the protocol can predefine a global reconfiguration domain. At this time, the first signaling belongs to the global reconfiguration domain, and the A-IoT network device globally reconfigures the A-IoT terminal device through the first signaling.

Step 2102: The A-IOT network device sends a fourth signaling to the A-IOT terminal device.

In some embodiments, the fourth signaling may be used to indicate a first time period, and the A-IOT terminal device stops sending uplink signals when the first time period ends.

In some embodiments, the uplink signal may be an uplink receiving (UR) signal.

In some embodiments, the measurement unit of the first time period 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 first time period may be indicated by the A-IoT network device or may be predefined by a protocol. Preferably, the first time period may be predefined by a protocol.

In some embodiments, this step is an optional step, and the A-IOT network device may not indicate the repeated transmission time of the A-IOT terminal device through the fourth signaling.

Step 2103: The A-IOT terminal device determines a first time period.

In some embodiments, the A-IOT terminal device can determine the first time period based on the fourth signaling, and continuously send uplink signals within the first time period without limiting the number of transmissions. After the first time period ends, the A-IOT terminal device stops sending the UR signal.

In some embodiments, the A-IOT terminal device continuously sends uplink signals within a first time period, and may send UR signals across multiple time slots. This method weakens the concepts of time slots and uplink shared physical channels (Physical Uplink Share CHannel, PUSCH) to a certain extent.

In some embodiments, this step is an optional step. When the A-IOT network device does not use the fourth signaling to indicate the repetition time of the A-IOT terminal device, the A-IOT terminal device may not determine the first time period.

Step 2104: The A-IOT network device sends a fifth signaling to the A-IOT terminal device.

In some embodiments, the fifth signaling may be used to indicate one or more random sets, and the one or more random sets are associated with the number of times the A-IOT terminal device performs repeated transmission.

In some embodiments, the random set may be a set of Q values.

In some optional embodiments, the association between one or more random sets and the number of times the A-IOT terminal device repeats transmission may be Therefore, one set corresponds to one number of repeated transmissions. For example, the number of repeated transmissions corresponding to set A is 2 times, and the number of repeated transmissions corresponding to set B is 3 times.

In some embodiments, the one or more random sets may also be predefined and determined by a protocol.

In some embodiments, this step is optional, and the A-IOT network device may not indicate the number of repeated transmissions to the A-IOT terminal device through the fifth signaling.

Step 2105: The A-IOT terminal device determines the first set.

In some embodiments, the A-IOT terminal device may determine the first set based on one or more random sets predefined by the protocol or indicated by the fifth signaling sent by the A-IOT network device.

In some embodiments, after the A-IOT terminal device receives the fifth signaling, it can determine the first set from one or more sets indicated by the fifth signaling, and the A-IOT terminal device can determine a backoff counter in the first set. Each time the A-IOT terminal device is scheduled, the value of the backoff counter is reduced by one. When the backoff counter is cleared, the A-IOT terminal device begins to send an uplink signal. The backoff counter can be used to stagger the uplink signals sent by multiple A-IOT terminal devices to reduce the probability of collision.

In some embodiments, this step is optional, and the A-IOT network device may not indicate the number of repeated transmissions of the A-IOT terminal device through the fifth signaling. In this case, the A-IOT terminal device may not determine the first set.

Step 2106: The A-IOT network device sends a sixth signaling to the A-IOT terminal device.

In some embodiments, the sixth signaling may be used to indicate the priority of the A-IOT terminal device, and the priority is associated with the number of times the A-IOT terminal device performs repeated transmission.

In some optional embodiments, the correlation between the priority and the number of repeated transmissions performed by the A-IOT terminal device may be that one priority corresponds to one number of repeated transmissions. For example, in one implementable method, the protocol predefines that the A-IOT terminal device with the first priority transmits uplink 4 times, and the A-IOT terminal device with the second priority transmits uplink 2 times.

In some embodiments, this step is optional, and the A-IOT network device may not indicate the number of repeated transmissions to the A-IOT terminal device through the sixth signaling.

Step 2107: The A-IOT terminal device determines the priority of the A-IOT terminal device.

In some embodiments, the priority of the A-IOT terminal device may be configured by the network or may be predefined by a protocol.

In some embodiments, this step is optional, and the A-IOT network device may not indicate the number of repeated transmissions of the A-IOT terminal device through the sixth signaling. At this time, the A-IOT terminal device may not determine the priority of the A-IOT terminal device.

Step 2108: The A-IOT terminal device determines the number of repetitions.

In some embodiments, the A-IOT terminal device can determine the number of repeated transmissions based on the first signaling.

In some embodiments, when the first signaling is used for the first service, the method by which the A-IOT terminal device determines the number of repetitions may be any one of the following:

Method 1

In some embodiments, the first signaling may include at least one indication bit, which may be used to indicate whether the A-IOT terminal device should repeat the first service. For example, when the indication bit is equal to 0, it indicates non-repetition; when the indication bit is equal to 1, it indicates repetition. Alternatively, when the indication bit is equal to 0, it indicates non-repetition; when the indication bit is equal to 1, it indicates repetition.

In some embodiments, when the first signaling instructs the A-IOT terminal device to send for the first service, the A-IOT terminal device may repeat the transmission N times, where the value of N is a subset of a positive integer. The specific value of N may be predefined by the protocol.

Method 2

In some embodiments, the first signaling may include at least one indication bit, and one indication bit may be used to indicate the number of times the A-IOT terminal device repeats the first service. For example, when the first signaling indicates that the number of times the A-IOT terminal device repeats the first service is 3, the A-IOT terminal device will send three uplink signals when performing uplink transmission for the first service.

In some embodiments, when the first signaling instructs the A-IOT terminal device to repeat the first service but does not indicate the number of repetitions, and the protocol predefines no value for the number of repetitions, the number of repetitions can be regarded as 1, that is, no repetition is performed.

In some embodiments, when the first signaling is used for the first object, the method by which the A-IOT terminal device determines the number of repetitions may be any one of the following:

Method 1

In some embodiments, the first signaling may include at least one indication bit, and an indication bit may be used to indicate whether the A-IOT terminal device is Whether to repeat the first object, for example, when the indication bit is equal to 0, it represents non-repetition; when the indication bit is equal to 1, it represents repetition. Alternatively, when the indication bit is equal to 0, it represents non-repetition; when the indication bit is equal to 1, it represents repetition.

In some embodiments, when the first signaling instructs the A-IOT terminal device to repeatedly send the first object, the A-IOT terminal device may repeat the transmission N times, where the value of N is a subset of a positive integer. The specific value of N may be predefined by the protocol.

Method 2

In some embodiments, the first signaling may include at least one indication bit, and one indication bit may be used to indicate the number of times the A-IOT terminal device repeats sending for the first object. For example, when the first signaling indicates that the number of times the A-IOT terminal device repeats for the first object is 3, the A-IOT terminal device will send three uplink signals when performing uplink sending for the first object.

In some embodiments, when the first signaling instructs the A-IOT terminal device to repeat for the first object but does not indicate the number of repetitions, and the protocol predefines no value for the number of repetitions, the number of repetitions can be regarded as 1, that is, no repetition is performed.

Method 3

In some embodiments, the first signaling may include at least one indicator bit, and one indicator bit may be used to indicate whether the second signaling in the first object is to be repeated. When the first signaling indicates that the second signaling in the first object is to be repeated, all transmissions performed by the A-IOT terminal device in response to the second signaling need to be repeated. For example, when the indicator bit is equal to 0, it indicates non-repetition; when the indicator bit is equal to 1, it indicates repetition. Alternatively, when the indicator bit is equal to 0, it indicates non-repetition; when the indicator bit is equal to 1, it indicates repetition.

Similar to the above method, when the first signaling indicates that the second signaling in the first object is to be repeatedly sent, it may be repeatedly sent N times, where the value of N is a subset of a positive integer. The specific value of N may be predefined by the protocol.

Method 4

In some embodiments, the first signaling may include at least one indication bit, and one indication bit may be used to indicate the number of times the second signaling in the first object is repeated. For example, when the first signaling indicates that the A-IOT terminal device repeats the second signaling in the first object three times, the A-IOT terminal device sends an uplink signal three times in response to the second signaling.

In some embodiments, when the first signaling instructs the A-IOT terminal device to repeat the second signaling in the first object, but does not indicate the number of repetitions, and the protocol predefines no value for the number of repetitions, the number of repetitions can be regarded as 1, that is, no repetition is performed.

Method 5

In some embodiments, the first signaling can use an indication bit to indicate whether the second service in the first object is to be repeated. When the first signaling indicates that the second service in the first object is to be repeated, the A-IOT terminal device needs to repeat when performing uplink transmission of the second service.

Similar to the above method, when the first signaling indicates that the second service in the first object is to be repeatedly sent, it may be repeatedly sent N times, where the value of N is a subset of a positive integer. The specific value of N may be predefined by the protocol.

Method 6

In some embodiments, the first signaling may use an indication bit to indicate the number of times the second service in the first object is repeatedly transmitted. For example, when the first signaling indicates that the A-IOT terminal device repeats the second service in the first object three times, the A-IOT terminal device will send three uplink signals when performing uplink transmission of the second service.

In some embodiments, when the first signaling instructs the A-IOT terminal device to repeat the second service in the first object, but does not indicate the number of repetitions, and the protocol predefines no value for the number of repetitions, the number of repetitions can be regarded as 1, that is, no repetition is performed.

In some embodiments, the A-IOT terminal device can determine the number of repeated transmissions corresponding to the first set, that is, the A-IOT terminal device can determine the number of repeated transmissions based on the association between the first set and the number of repeated transmissions of the A-IOT terminal device.

In the above embodiment, the A-IoT terminal device can randomly select a Q value in the first set. In this case, the number of repetitions by the A-IoT terminal device can be the number of repetitions predefined by the protocol associated with the set. If the A-IoT terminal device randomly selects a Q value in the first set, the number of repetitions can also be determined according to the protocol predefined number. For example, if the A-IoT terminal device randomly selects a Q value in the first set, the uplink transmission is N times. Otherwise, the uplink transmission is M times. N/M can be predefined by the protocol, and its value set is a subset of positive integers.

In some embodiments, the A-IoT terminal device can determine the number of retransmissions corresponding to the priority level. Specifically, the A-IoT terminal device can determine the number of retransmissions based on the correlation between the priority level and the number of retransmissions by the A-IoT terminal device. For example, if the A-IoT terminal device is configured with the first priority level, the uplink transmission is N times. Otherwise, the uplink transmission is M times. N/M is predefined by the protocol, and its value set is a subset of positive integers.

Step 2109: The A-IOT network device sends a continuous wave (CW) signal to the A-IOT terminal device.

In some embodiments, the A-IOT terminal device can send a UR signal to the A-IOT network device based on the backscattering of the CW signal to achieve uplink transmission.

In some embodiments, the continuous wave (Continuous Wave) signal and the excitation signal both refer to the same signal, namely, a CW signal. The excitation signal can be a continuous wave, but is not limited to this. It can also be other signals used to enable the A-IoT terminal device to send uplink signals based on backscattering. The names of excitation and continuous wave can be interchangeable.

In some embodiments, the CW signal is a continuous signal in the time domain occupying a certain bandwidth. For example, the CW signal may also be an impulse signal in the frequency domain.

Step 2110: The A-IOT terminal device sends an uplink signal to the A-IOT network device.

In some embodiments, the A-IOT network device may receive a UR signal repeatedly sent by the A-IOT terminal device for the first service under a first condition. That is, the A-IOT terminal device may determine the number of times the UR signal is repeatedly sent for the first service and upload the UR signal according to the number of times.

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

The first information instructs the A-IOT terminal device to repeatedly send the first service;

The number of times indicated by the second information is greater than or equal to 2.

In some embodiments, under the second condition, the A-IOT network device may receive a UR signal repeatedly sent by the A-IOT terminal device for the first object.

In some embodiments, the second condition includes at least one of the following:

The third information instructs the A-IOT terminal device to repeatedly send the first object;

The number of times indicated by the fourth information is greater than or equal to 2;

The fifth information instructs the A-IOT terminal device to repeatedly send the second signaling in the first object;

The number of times indicated by the sixth information is greater than or equal to 2;

The seventh information instructs the A-IOT terminal device to repeatedly send the second service in the first object;

The number of times indicated by the eighth information is greater than or equal to 2.

Step 2111: The A-IOT network device sends a third signaling to the A-IOT terminal device.

In some embodiments, the third signaling may be used to instruct the A-IOT terminal device to stop sending the UR signal. That is, the third signaling may be used to instruct the A-IOT terminal device to stop uplink transmission.

In some embodiments, when the A-IoT network device triggers the A-IoT terminal device to send an uplink signal, the A-IoT terminal device may continue to send an uplink signal before receiving the third signaling.

For example, step 2101 can be implemented as an independent embodiment, steps 2101+2102+2103+2104+2105+2106+2107+2108+2109+2110+2111 can be implemented as an independent embodiment, steps 2101+2102+2103+2108+2109+2110+2111 can be implemented as an independent embodiment, and steps 2101+2104+2105+2106+2107+2108+2109+2110+2111 can be implemented as an independent embodiment. 108+2109+2110+2111 can be implemented as an independent embodiment, steps 2101+2106+2107+2108+2109+2110+2111 can be implemented as an independent embodiment, steps 2101+2108+2109+2110+2111 can be implemented as an independent embodiment, and steps 2101+2108+2109+2110 can be implemented as an independent embodiment, but are not limited to this.

The following is an exemplary introduction to the above method.

The method shown in the embodiment of the present disclosure relates to a repeated transmission system and method applicable to A-IoT devices.

In some embodiments, repeated transmission is the repeated sending mentioned above.

In a network, A-IoT network devices communicate with A-IoT end devices. A-IoT network devices include base stations, terminals, intermediate nodes, and auxiliary nodes. A-IoT end devices are classified into Type A, Type B, and Type C. An A-IoT network device sends an excitation signal to at least one A-IoT end device. The excitation signal can be used to trigger communication with the A-IoT end device, transmitting control signaling and data. Optionally, the excitation signal can also be used as a charging energy source for the A-IoT end device.

To enhance coverage, existing NR mechanisms typically configure a repetition factor to repeat data transmission, achieving a better coverage enhancement. Existing retransmission configuration methods primarily utilize semi-static or dynamic methods, with dynamic instructions increasing signaling overhead. For A-IoT devices, Type A and Type B devices face difficulties with time-frequency synchronization and the risk of power outages, making semi-static resource location difficult.

Therefore, to address the above issues, this example designs a repeated transmission method mainly in the following aspects:

1. Conventional solution: Use semi-static configuration or dynamically indicate whether the A-IoT device needs to repeat transmission and the number of repetitions.

2. Global configuration: This is a one-time configuration that can be configured to repeat for all transmissions, or to repeat for specific instructions or specific services.

3. Termination mechanism: This method uses an A-IoT network device to trigger the A-IoT terminal device to continue transmitting, with no limit on the number of times, until the A-IoT network device instructs the device to terminate transmission. Another termination mechanism uses an A-IoT network device to trigger the A-IoT terminal device to continue transmitting, with no limit on the number of times, within a certain time domain. This mechanism weakens the concepts of time slots and PUSCH.

This example is described in detail below through the following embodiments.

Example 1

This embodiment is a conventional solution, and can semi-statically configure or dynamically indicate whether knowledge transmission needs to be repeated, and the number of repetitions. After being triggered, the A-IoT terminal device performs uplink or downlink transmission according to the first indication field of the first instruction. The method for determining the first indication field includes at least one of the following:

Method 1

The protocol predefines a repeat indication field, which includes at least one indication bit and is carried by the first instruction.

In some embodiments, the repeat indication field is used to indicate whether the uplink transmission of the A-IoT terminal device in response to the first instruction is repeated. For example, when the indication bit is equal to 0, it can represent non-repetition; when the indication bit is equal to 1, it can represent repetition. Alternatively, when the indication bit is equal to 0, it represents non-repetition; when the indication bit is equal to 1, it represents repetition.

In some embodiments, the type of the first instruction may include dynamic, semi-static, or static.

Furthermore, the protocol predefines that once repetition is indicated, the number of repetitions is N. The value of N is a subset of positive integers.

Method 2

The protocol predefines a repetition number indication field, which includes at least one indication bit and is carried by the first instruction.

In some embodiments, the repetition count indication field is used to indicate the number of times the A-IoT terminal device sends an uplink transmission in response to the first instruction.

In some embodiments, the type of the first instruction may include dynamic, semi-static, or static.

Furthermore, the protocol predefines that if the number of repetitions is not indicated, the number of repetitions is 1.

Example 2

This embodiment is a global configuration solution, that is, once configured, it is repeated for all transmissions. It can also be repeated for specific instructions or specific services. After being triggered, the A-IoT terminal device performs uplink transmission according to the second indication field of the second instruction. The method for determining the second indication field includes at least one of the following:

Method 1

The protocol predefines a global reconfiguration domain, which is carried by the second instruction. The A-IoT network device uses the second instruction to perform global reconfiguration on the A-IoT terminal device.

In some embodiments, the global repetition configuration field includes at least one indicator bit for indicating whether the uplink transmission performed by the A-IoT terminal device in response to the A-IoT network device is repeated. For example, when the indicator bit is equal to 0, it can indicate non-repetition; when the indicator bit is equal to 1, it indicates repetition. Alternatively, when the indicator bit is equal to 0, it indicates non-repetition; when the indicator bit is equal to 1, it indicates repetition.

In some embodiments, the type of the second instruction may include dynamic, semi-static, or static.

Furthermore, the protocol predefines that once global repetition is indicated, the number of repetitions is N. The value of N is a subset of positive integers.

Method 2

The protocol predefines a global repetition count configuration field, which is carried by the second instruction. The A-IoT network device uses the second instruction to perform global repetition configuration on the A-IoT terminal device.

In some embodiments, the global repetition configuration field includes at least one indication bit for indicating the number of times the uplink transmission is repeated by the A-IoT terminal device in response to the A-IoT network device.

In some embodiments, the type of the second instruction may include dynamic, semi-static, or static.

Furthermore, the protocol predefines that if global repetition is not indicated, the number of repetitions is 1.

Method 3

The protocol predefines a repeated configuration field, which is carried by the second instruction.

In some embodiments, the A-IoT network device can repeatedly configure the first object corresponding to the A-IoT terminal device through a second instruction. The first object includes at least one of the third instruction sent by the A-IoT network device and the first service corresponding to the A-IoT terminal device. When the first object is the third instruction sent by the A-IoT network device, and the corresponding indication of the repeat configuration field is repeat, the uplink transmission in response to the third instruction received by the A-IoT terminal device is repeated. When the first object is the first service corresponding to the A-IoT terminal device, and the corresponding indication of the repeat configuration field is repeat, the A-IoT terminal device repeats when performing uplink transmission of the first service.

In some embodiments, the repetition configuration field may include at least one repetition configuration subfield, each subfield including at least one indicator bit for indicating whether the corresponding first object is a repetition. For example, when the indicator bit is equal to 0, it indicates non-repetition; when the indicator bit is equal to 1, it indicates repetition. Alternatively, when the indicator bit is equal to 0, it indicates non-repetition; when the indicator bit is equal to 1, it indicates repetition.

In some embodiments, the type of the second instruction may include dynamic, semi-static, or static.

Furthermore, the protocol predefines that once the first object is instructed to repeat, the number of repetitions is N. The value of N is a subset of positive integers.

Method 4

The protocol predefines a repetition count configuration field, which is carried by the second instruction.

In some embodiments, the A-IoT network device can configure the number of repetitions of the first object corresponding to the A-IoT terminal device through a second instruction. The first object includes at least one of a third instruction sent by the A-IoT network device and a first service corresponding to the A-IoT terminal device. When the first object is the third instruction sent by the A-IoT network device, and the number of repetitions indicated by the repetition configuration field is greater than 1, the uplink transmission in response to the third instruction received by the A-IoT terminal device is repeated. When the first object is the first service corresponding to the A-IoT terminal device, and the number of repetitions indicated by the repetition configuration field is greater than 1, the A-IoT terminal device repeats when performing uplink transmission of the first service.

In some embodiments, the repetition number configuration field includes at least one repetition configuration subfield, and each subfield includes at least one indication bit for indicating the repetition number of the corresponding first object.

In some embodiments, the type of the second instruction may include dynamic, semi-static, or static.

Furthermore, the protocol predefines that if the number of repetitions of the first object is not indicated, the number of repetitions is 1.

Example 3

This embodiment is a termination mechanism. When the A-IoT terminal device is triggered, it performs uplink transmission according to the predefined rules of the protocol. The method includes at least one of the following:

Method 1

The protocol predefines termination signaling, which is used by the A-IoT network device to terminate an ongoing uplink transmission by the A-IoT terminal device. When the A-IoT network device triggers an A-IoT terminal device to perform an uplink transmission, the A-IoT terminal device continues to respond with uplink transmissions until the A-IoT network device sends the termination signaling.

Method 2

After the A-IoT network device is triggered, the A-IoT terminal device continues to transmit within the first time domain, with no limit on the number of times. The measurement unit of the first time domain range can be absolute time units or relative time units, such as milliseconds, microseconds, seconds, minutes, time domain symbols, time slots, radio frames, and radio subframes.

Example 4

This embodiment can be combined with the Q value set and priority, and repeated transmission can be performed through the binding relationship predefined by the protocol and the specific priority itself, so as to achieve the purpose of ensuring high-priority uplink coverage. After the A-IoT terminal device is triggered, uplink transmission is performed according to the predefined rules of the protocol. The method includes at least one of the following:

Method 1

Define a first Q value set. If the A-IoT terminal device uses a random Q value in the Q value set, it sends the uplink message N times. Otherwise, it sends the uplink message M times. N\M is predefined by the protocol and its value set is a subset of positive integers.

Method 2

Define the first priority. When the A-IoT terminal device is configured with the first priority, the uplink is sent N times. Otherwise, the uplink is sent M times. N\M is predefined by the protocol and its value set is a subset of positive integers.

In one implementation, the protocol predefines that high-priority uplinks are sent four times and low-priority uplinks are sent two times.
