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

[0119] 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.

[0120] 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 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.

[0121] 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.

[0122] 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 user equipment terminal, an intermediate node, or an auxiliary node (X note) 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.

[0123] For A-IoT devices using backscatter, they need a continuous wave (CW) energy source (CW node) to provide electromagnetic waves for reflection while transmitting data. CW waves typically have a constant amplitude. The CW node can be a separate node or a base station or intermediate node (such as a user end user) that communicates with the A-IoT device.

[0124] The frequency of the electromagnetic wave reflected by the A-IoT device can be exactly the same as the CW frequency, or there can be some offset. The offset value is related to the hardware characteristics of the A-IoT device. The offset value may be a fixed value. If the A-IoT device hardware supports it, it may also support multiple fixed values ​​or a dynamically adjustable value.

[0125] Because A-IoT devices cannot withstand extended power outages, prolonged downlink signal interruptions can cause them to lose potential information or incorrectly refresh the receiving start point. Therefore, determining a waveform suitable for network communication with A-IoT devices is the primary focus of this solution.

[0126] To address the above issues, this disclosure proposes a communication method based on the ambient Internet of Things (AIoT) that can determine a signal waveform suitable for A-IoT devices. The details of this method are as follows.

[0127] 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 an A-IoT terminal device 102. The method includes:

[0128] In step 2101, the A-IoT network device sends a first signaling to the A-IoT terminal device, where the first signaling is transmitted via a first waveform.

[0129] In some embodiments, the A-IoT network device can send a first signaling to the A-IoT terminal device to communicate with the A-IoT terminal device, wherein the first signaling is transmitted through a first waveform, which can maintain the basic operation of the A-IoT terminal device and avoid data loss caused by the A-IoT terminal device being powered off for a long time, or incorrectly refreshing the receiving starting point.

[0130] In some embodiments, the method for determining the first waveform may include at least one of the following methods.

[0131] Method 1

[0132] In some embodiments, the first symbol of the first waveform is a first coding value; the second symbol of the first waveform is a second coding value; wherein the first coding value and / or the second coding value correspond to a first key value and / or a second key value, the power coefficient of the first key value is normalized to 1, and the power coefficient of the second key value is greater than zero and less than 1 after normalization.

[0133] In the above embodiment, when any one of Methods 1 to 3 is adopted, the first waveform may be an enhanced OOK waveform (enhanced OOK), and the OFF symbol of the enhanced OOK may be composed of a non-zero duration. The minimum unit of duration may be 1 / N time domain symbols, where N is a natural number greater than 0. Preferably, the value of N may be 1 / 2, 1 / 4, 1 / 8, 1 / 16, 1 / 3, 1 / 5, 1, 2, 3, 4, 5, 8, 16, and the like.

[0134] In some embodiments, the first symbol and the second symbol may be Orthogonal Frequency Division Multiplexing (OFDM) symbols.

[0135] In some embodiments, the first coding value and / or the second coding value correspondingly include a first key value and / or a second key value, wherein the first key value and / or the second key value can be "ON" or "OFF".

[0136] In some embodiments, the first coded value may be obtained by using Manchester coding on the first symbol. For example, the first coded value may be “OFF, ON” or “ON, OFF”.

[0137] In some embodiments, the second coded value may be obtained by using Manchester encoding on the second symbol. For example, the second coded value may be "OFF, ON" or "ON, OFF".

[0138] Method 1 can use the first coding value and the second coding value to distinguish data. For example, when the data is 0, the corresponding first coding value can be "OFF, ON", and when the data is 1, the corresponding second coding value is "ON, OFF". Then, when the data "01001010" is transmitted, the code corresponding to the data can be composed of the first coding value and the second coding value, which is "OFF, ON", "ON, OOF", "OFF, ON", "OFF, ON", "ON, OOF", "OFF, ON", "ON, OOF", "OFF, ON".

[0139] In some embodiments, when any of methods 1 to 3 is used, the normalized power coefficient of the second key value is greater than zero and less than 1. That is, the power coefficient corresponding to the OFF symbol can be greater than 0 and less than 1, that is, there is still a certain amount of power in the OFF symbol. Since the A-IoT terminal device can obtain energy for uplink transmission by receiving the downlink signal of the A-IoT network device, this power can still provide energy for the A-IoT terminal device when the downlink signal is interrupted, thereby maintaining the basic operation of the A-IoT terminal device and avoiding power outage of the A-IoT terminal device.

[0140] Method 2

[0141] In some embodiments, the first coding value and / or the second coding value of the first waveform correspond to at least one first key value and at least one second key value, the sum of the amplitudes of the subcarriers corresponding to at least one first key value is greater than the sum of the amplitudes of the subcarriers corresponding to at least one second key value, and there is at least one subcarrier corresponding to the second key value whose amplitude is greater than zero.

[0142] In some embodiments, the amplitudes of the subcarriers corresponding to the second key values ​​may not all be greater than zero. The amplitudes of some of the subcarriers corresponding to the second key values ​​may be greater than zero, and the amplitudes of the subcarriers corresponding to the remaining second key values ​​may be equal to zero. However, there must be at least one subcarrier corresponding to the second key value whose amplitude is greater than zero. For example, there are 5 OFF symbols, and the amplitudes of the subcarriers corresponding to 2 OFF symbols may be a, which is greater than zero and less than the amplitude of the subcarrier corresponding to the ON symbol. The amplitudes of the subcarriers corresponding to the remaining three OFF symbols are 0.

[0143] In some embodiments, method 2 may define the first waveform as a waveform in which the sum of the amplitudes of the subcarriers corresponding to all ON symbols is greater than the sum of the amplitudes of the subcarriers corresponding to all OFF symbols.

[0144] Method 3

[0145] In some embodiments, the first coding value and / or the second coding value of the first waveform correspond to at least one first key value and at least one second key value, the statistical value of the sum of the amplitudes of the subcarriers corresponding to at least one first key value is greater than the statistical value of the sum of the amplitudes of the subcarriers corresponding to at least one second key value, and there is at least one subcarrier corresponding to the second key value whose amplitude is greater than zero.

[0146] Similar to method 2, in method 3, the amplitudes of the subcarriers corresponding to the second key values ​​may not all be greater than zero. The amplitudes of some subcarriers corresponding to the second key values ​​may be greater than zero, and the amplitudes of the subcarriers corresponding to the remaining second key values ​​may be equal to zero, but at least one subcarrier corresponding to the second key value must have an amplitude greater than zero.

[0147] In some embodiments, the statistical value in method 3 can be the average of the amplitudes corresponding to the same type of key-value subcarriers. Method 3 can define the first waveform as the average amplitude of the subcarriers corresponding to all ON symbols, which is greater than the waveform of the average amplitude of the subcarriers corresponding to all OFF symbols.

[0148] Method 4

[0149] In some embodiments, each of the one or more third symbols of the first waveform includes a first number of interruptions, the third symbol corresponds to a third coding value, and the total interruption duration of each third symbol is the same; each of the one or more fourth symbols of the first waveform includes a second number of interruptions, the fourth symbol corresponds to a fourth coding value, and the total interruption duration of each fourth symbol is the same; wherein, the first number of interruptions is not equal to the second number of interruptions.

[0150] In some embodiments, the interrupt may refer to an OFF symbol, for example.

[0151] In some embodiments, the interruption duration of each first interruption number is a first duration, and the interruption duration of each second interruption number is a second duration. The first duration and / or the second duration are predefined by the protocol.

[0152] In some embodiments, when using method 4 or method 5, the first waveform may be a zero-power number waveform, in which case a different number of zero-value interruptions are performed in each OFDM symbol. The interruption durations in time-domain symbols of the same type are the same. For example, the first duration can be represented by b, and the first duration of each third symbol is the same; the second duration can be represented by c, and the second duration is the same.

[0153] In the above embodiment, the first duration and the second duration may be equal or different, that is, the time lengths of b and c may be equal or different.

[0154] In some embodiments, the measurement units of the first duration and the second duration may be absolute time units or relative time units.

[0155] The absolute time unit includes but is not limited to at least one of the following: nanoseconds (ns), microseconds (us), milliseconds (ms), etc.

[0156] Relative time units include but are not limited to: time domain symbols, time domain sub-symbols, etc.

[0157] In some embodiments, the third symbol and the fourth symbol may be OFDM symbols.

[0158] In some embodiments, the third symbol includes a first number of interruptions, ie, the number of first durations. For example, there may be D first durations in the third symbol, ie, there are D interruptions in the third symbol.

[0159] In some embodiments, the fourth symbol includes a second number of interruptions, ie, the number of second durations. For example, there may be S second durations in the fourth symbol, ie, there are S interruptions in the fourth symbol.

[0160] In some embodiments, the first interruption count is not equal to the second interruption count, that is, D and S are not equal. The A-IoT terminal device can distinguish the third symbol from the fourth symbol based on the different interruption counts. For example, zero can correspond to 2 interruptions, and b < 13us, and 1 can correspond to 1 interruption, and c < 13us. When the data is 01001010, the corresponding symbol interruption counts are 2, 1, 2, 2, 1, 2, 1, 2, 1.

[0161] In some embodiments, the third symbol of the first waveform is a third coding value; the fourth symbol of the first waveform is a fourth coding value; wherein the third coding value corresponds to a first quantity of first key values ​​and a second quantity of second key values, the fourth coding value corresponds to a third quantity of first key values ​​and a fourth quantity of second key values, the power coefficient of the first key value is a, the power coefficient of the second key value is zero, the first quantity is not equal to the third quantity, and / or the second quantity is not equal to the fourth quantity.

[0162] In some embodiments, the third code value and / or the fourth code value correspondingly includes a first number of first key values ​​and a second number of second key values, wherein the first key value and the second key value can be "ON" or "OFF".

[0163] In some embodiments, the third coded value may be obtained by using Manchester encoding on the first symbol. For example, the third coded value may be "OFF, ON" or "ON, OFF".

[0164] In some embodiments, the fourth coded value may be obtained by using Manchester coding on the second symbol. For example, the fourth coded value may be "OFF, ON" or "ON, OFF".

[0165] In some optional embodiments, when method 4 or 5 is adopted, the power coefficient a of the first key value may be 1 after normalization, and may be greater than 1 when the power coefficient a of the first key value is not normalized.

[0166] In some embodiments, method 4 can use different numbers of first key values ​​and second key values ​​to distinguish the third symbol from the fourth symbol. For example, the third symbol can include two first key values ​​and three second key values, and the fourth symbol can include one first key value and four second key values. For example, the second key value can correspond to the above-mentioned interruption, that is, the first waveform can be interrupted at the second key value.

[0167] In some embodiments, for example, the first quantity and the third quantity can be restricted to be unequal, and the second quantity and the fourth quantity are not restricted. For example, the third symbol can include 2 first key values ​​and 3 second key values, and the fourth symbol can include 1 first key value and 3 second key values; or, the second quantity and the fourth quantity can be restricted to be unequal, and the first quantity and the third quantity are not restricted. For example, the third symbol can include 2 first key values ​​and 3 second key values, and the fourth symbol can include 2 first key values ​​and 4 second key values; or the first quantity and the third quantity are unequal, and the second quantity and the fourth quantity are also unequal.

[0168] Method 5

[0169] In some embodiments, each of the one or more third symbols of the first waveform includes a first number of interruptions, the third symbol corresponds to a third coding value, and the total uninterrupted time length of each third symbol is the same; each of the one or more fourth symbols of the first waveform includes a second number of interruptions, the fourth symbol corresponds to a fourth coding value, and the total uninterrupted time length of each fourth symbol is the same; wherein, the first number of interruptions is not equal to the second number of interruptions.

[0170] In some embodiments, for example, the total uninterrupted duration of a third symbol can be represented by d, and the total uninterrupted duration of a fourth symbol can be represented by e, then the total uninterrupted duration d of each third symbol is the same, and the total uninterrupted duration e of each fourth symbol is the same.

[0171] In some embodiments, the measurement units of d and e can be absolute time units or relative time units.

[0172] The absolute time unit includes but is not limited to at least one of the following: nanoseconds (ns), microseconds (us), milliseconds (ms), etc.

[0173] Relative time units include but are not limited to: time domain symbols, time domain sub-symbols, etc.

[0174] In some embodiments, similar to method 4, method 5 can define the number of interruptions for the third symbol and the fourth symbol, and distinguish the third symbol from the fourth symbol based on the number of the first key value and the second key value. Unlike method 4, method 4 defines the duration of the interruption, while method 5 defines the total uninterrupted duration. For example, zero can correspond to 3 uninterrupted (ON) symbols, and b<13us, 1 corresponds to 2 ON times, and c<13us. When the data is 01001010, the corresponding symbol ON times are 3, 2, 3, 3, 2, 3, 2, 3, 2.

[0175] In some embodiments, the first value or the second value of the data corresponding to the one or more first symbols may include at least one of the following: at least one first encoding value; at least one second encoding value; at least one third encoding value; or at least one fourth encoding value. That is, a piece of data may be represented by at least one first key value and at least one second key value.

[0191] The following is an exemplary introduction to the above method.

[0192] The method shown in the embodiment of the present disclosure relates to a repeated transmission system and method applicable to A-IoT devices.

[0193] 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.

[0194] A-IoT devices usually have a simpler structure and generally do not support energy storage or have weak energy storage. Therefore, they cannot operate during a long power outage. If the downlink signal is interrupted for too long, the A-IoT device will lose potential information or incorrectly refresh the reception starting point. Therefore, it is necessary to determine a waveform suitable for A-IoT device communication.

[0195] The first waveform adopted by the downlink signal sent by the A-IoT network device to the A-IoT terminal device is determined through several embodiments below.

[0196] Embodiment 1

[0197] As shown in Figure 6, when the protocol predefines an enhanced OOK (enhanced OOK) waveform, the OFF symbol of enhanced OOK consists of the duration of a non-zero value. The first waveform can be determined by the following three methods.

[0198] Method 1

[0199] The power coefficient of the OFF symbol of the first waveform can be greater than 0 and less than the power coefficient of the ON symbol. At this time, the minimum component unit of the duration can be 1 / N time-domain symbols, where N is a natural number greater than 0. Preferably, N is 1 / 2, 1 / 4, 1 / 8, 1 / 16, 1 / 3, 1 / 5, 1, 2, 3, 4, 5, 8, 16. Taking the waveform below Figure 6 as an example, the power coefficient of the ON symbol is 1, and the power coefficient of the OFF is a, where the value range of a is 0 < a < 1. When the data is 01001010, the corresponding symbols are encoded using Manchester coding as "OFF, ON", "ON, OOF", "OFF, ON", "OFF, ON", "ON, OOF", "OFF, ON", "ON, OOF", "OFF, ON".

[0200] Method 2

[0201] In some embodiments, the amplitudes of the subcarriers corresponding to the OFF symbol may not all be 0, and the sum of the amplitudes is less than the sum of the amplitudes of the subcarriers corresponding to the ON symbol. At this time, the amplitudes of the subcarriers corresponding to the OFF symbol may not be equal. For example, the amplitude of the subcarrier corresponding to some OFF symbols is 0, while the amplitude of the subcarrier corresponding to some OFF symbols is a. However, the sum of the amplitudes of all subcarriers corresponding to the OFF symbol is less than the sum of the amplitudes of the subcarriers corresponding to the ON symbol.

[0202] Method 3

[0203] In some embodiments, the amplitudes of the subcarriers corresponding to the OFF symbols may not all be 0, and their average amplitude may be smaller than the average amplitude of the subcarriers corresponding to the ON symbols. In this case, the amplitudes of the subcarriers corresponding to the OFF symbols may be unequal, for example, the amplitudes of the subcarriers corresponding to some OFF symbols may be 0, while the amplitudes of the subcarriers corresponding to some OFF symbols may be a. However, the average amplitude of the subcarriers corresponding to all OFF symbols is smaller than the average amplitude of the subcarriers corresponding to the ON symbols.

[0204] Example 2

[0205] As shown in FIG7 , when the protocol predefines a zero-power number waveform, different numbers of zero-value interruptions can be performed in each OFDM symbol.

[0206] Method 1

[0207] The duration of the interruptions b in time-domain symbols of the same type is the same. The duration of the interruptions c in time-domain symbols of the same type is the same. b and c are predetermined by the protocol and may or may not be the same.

[0208] In some embodiments, the measurement units of b and c can be absolute time units or relative time units.

[0209] The absolute time unit includes but is not limited to at least one of the following: nanoseconds (ns), microseconds (us), milliseconds (ms), etc.

[0210] Relative time units include but are not limited to: time domain symbols, time domain sub-symbols, etc.

[0211] The first type of time-domain symbol consists of D b's, and the second type of symbol consists of S c's, where D and S are not equal. Taking the waveform at the bottom of Figure 7 as an example, 0 corresponds to two interruptions, with b < 13 μs, and 1 corresponds to one interruption, with c < 13 μs. For the data 01001010, the corresponding symbol has the following interruption times: 2, 1, 2, 2, 1, 2, 1, 2, 1.

[0212] Method 2

[0213] The duration of uninterrupted d in time-domain symbols of the same type is the same. The duration of uninterrupted e in time-domain symbols of the same type is the same. d and e are predetermined by the protocol and may or may not be the same.

[0214] In some embodiments, the measurement units of d and e can be absolute time units or relative time units.

[0215] The absolute time unit includes but is not limited to at least one of the following: nanoseconds (ns), microseconds (us), milliseconds (ms), etc.

[0216] Relative time units include but are not limited to: time domain symbols, time domain sub-symbols, etc.

[0217] In some embodiments, the first-type time-domain symbol consists of D ds, and the second-type symbol consists of S e, where D and S are not equal. Taking Figure 7 as an example, 0 corresponds to 3 ON times, and b < 13 us, and 1 corresponds to 2 ON times, and c < 13 us. When the data is 01001010, the corresponding symbol ON times are 3, 2, 3, 3, 2, 3, 2, 3, 2.
