[0112] In recent years, the Internet of Things (IoT) has garnered significant attention in the field of wireless communication. Further reducing the size, complexity, and power consumption of IoT devices could enable the deployment of hundreds of billions or even trillions of IoT devices across various applications, providing added value throughout the value chain.

[0113] In related technologies, the energy used for D2R primarily comes from charging waves. An AIoT device with sufficient energy can successfully complete data transmission.

[0114] Discussions on the energy consumption of AIoT devices mainly cover the following aspects:

[0115] Whether the energy state is visible to the reader / writer;

[0116] How is the energy status represented, for example, by a level, or by displaying the charging status such as ON / OFF / Sleep;

[0117] The behavior and state transitions of AIoT devices under energy conditions.

[0118] On the other hand, the research scope of related technologies also includes the confirmation of the proximity range of AIoT devices. Using this technology, readers or networks can obtain basic information about whether an AIoT device is near the reader. This basic information can be based on whether the reader receives a D2R signal, or it can be based on pre-configured threshold information on the reader.

[0119] Current discussions on energy state and proximity determination mainly focus on physical layer design, while higher-level process design has not yet been discussed.

[0120] The relevant technologies have not yet defined how the network side or the reader manages the random access and data transmission of AIoT devices with different energy states, resulting in the problem of low reliability of uplink transmission between AIoT devices and readers.

[0121] Based on this, in various embodiments of this disclosure, the communication device sends first information; the first information indicates the correspondence between the access round and / or access opportunity for the AIoT device to initiate AIoT random access to the communication device and the energy state or energy level of the AIoT device. In the above scheme, since the first information can indicate the correspondence between the access round and / or access opportunity for the AIoT device to initiate AIoT random access to the communication device and the energy state or energy level of the AIoT device, the communication device can manage the AIoT random access and data transmission of AIoT devices with different energy states. This allows the AIoT device to select the access round and / or access opportunity to initiate AIoT random access to the communication device based on the first information, thereby improving the success rate of the AIoT device accessing the communication device and the success rate of the AIoT device sending data to the communication device, thus improving the reliability of uplink transmission between the AIoT device and the communication device.

[0122] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments.

[0123] This disclosure provides a device scheduling method applied to communication devices, including terminals and / or network devices. Terminals include, but are not limited to, one or more of mobile phones, tablets, laptops, and wearable devices; network devices include base stations. The communication device can be understood as a reader / writer. As shown in Figure 1, the method includes:

[0124] Step 101: Send the first message.

[0125] The first information indicates the access rounds and / or access opportunities for the AIoT device to initiate AIoT random access to the communication device, and corresponds to the energy state or energy level of the AIoT device.

[0126] Here, sending the first message can be described as sending a first message to an AIoT device, which is used by the AIoT device to select an access round and / or access opportunity. The communication device can send the first message or send the first message to the AIoT device using unicast, multicast, or broadcast methods.

[0127] The first information is used to allow the AIoT device to select the access round and / or access opportunity to initiate AIoT random access to the communication device. The first information may indicate one or more of the following:

[0128] The correspondence between the access rounds in which the AIoT device initiates random access to the communication device and the energy state of the AIoT device;

[0129] The correspondence between the access rounds initiated by the AIoT device to the communication device and the energy level of the AIoT device;

[0130] The correspondence between the access opportunities for an AIoT device to initiate a random AIoT access to the communication device and the energy state of the AIoT device;

[0131] The correspondence between the access opportunities for an AIoT device to initiate a random AIoT access to the communication device and the energy level of the AIoT device.

[0132] It should be noted that the first information includes, but is not limited to, one or more of the following: AIoT paging message, indication message preceding the AIoT paging message, select message, and query message. The first information can be used to indicate the access round and / or access opportunity for the AIoT device to send the first message to the communication device, and its correspondence with the energy state or energy level of the AIoT device. The first message includes, but is not limited to, one or more of the following: the third AIoT random access message (Message, Msg) 3, the instruction feedback message, the first AIoT random access message Msg1, and MsgA; the first AIoT random access message Msg1 can be RN16, where RN16 can be a 16-bit random number. One access round can contain multiple access opportunities. The AIoT device can be referred to as one or more of the following: tag, electronic tag, AIoT service terminal, response device (such as a response device for AIoT tasks or operations), ultra-low power terminal, ultra-low complexity terminal, near-zero power terminal, zero power terminal, etc. AIoT devices can be classified based on their energy source, backscatter technology, or whether they have active signal generation capabilities, energy storage capabilities, passive communication, or active communication, and can include multiple types of devices.

[0133] To ensure that communication devices and AIoT devices maintain a consistent understanding of the state of energy, it is necessary to clarify the specific meaning of the state of energy. Therefore, in one embodiment, the state of energy is defined as an ON state, a SLEEP state, or an energy-saving state; alternatively, the state of energy may refer to the energy level of the AIoT device.

[0134] Here, the energy level of an AIoT device can include one or more, such as E0, E1, and E2, with each energy level corresponding to an energy range; for example, E0 corresponds to 0.4-0.5 Joules (J); E1 corresponds to 0.2J-0.4J; and E2 corresponds to 0J-0.2J. The energy level can also be a percentage of charge, such as E0 corresponding to 60-100%; E1 corresponding to 20-60%; and E2 corresponding to 0-20%. It should be noted that the energy level can also be described as an energy state level.

[0135] To facilitate AIoT devices initiating random AIoT access to communication devices and improve the success rate of AIoT devices accessing communication devices, in one embodiment, the first information includes one or more of the following:

[0136] One or more access rounds;

[0137] Access opportunities included in each of one or more access rounds;

[0138] The correspondence between the energy state or energy level of AIoT devices and the access rounds and / or access opportunities.

[0139] To improve the efficiency of AIoT devices initiating random AIoT access to communication devices, in one embodiment, the correspondence between the energy state or energy level of the AIoT device and the access round and / or access opportunity indicates one or more of the following:

[0140] In the first N access rounds, AIoT devices with the Nth energy state or energy level are allowed to access or re-access, where N is a positive integer;

[0141] In the first N access rounds, at most N AIoT devices with different energy states or energy levels are allowed to access or re-access, where N is a positive integer;

[0142] The first M access opportunities in an access round allow the Mth AIoT device with the Mth energy state or energy level to access or re-access, where M is a positive integer;

[0143] The first M access opportunities in an access round allow at most M AIoT devices with different energy states or energy levels to access or re-access, where M is a positive integer.

[0144] Here, the values ​​of M and N can be the same or different.

[0145] For example, as shown in Figure 2, in the first N access rounds, AIoT devices with energy level En can be allowed to access or re-access, and AIoT devices with energy levels from E0 to En can be allowed to access or re-access, where n is an integer greater than or equal to 1.

[0146] For example, as shown in Figure 2, during the first M access opportunities of an access round, AIoT devices with energy level En can be allowed to access or re-access, or AIoT devices with energy levels from E0 to En can be allowed to access or re-access.

[0147] Considering that AIoT devices may fail to send data to the communication device or fail to access the device due to insufficient power, requiring the AIoT device to fall back, the communication device can indicate the fallback timing for the AIoT device. This provides a more reasonable charging time for the AIoT device that has failed to access the device or send data, enabling the AIoT device to re-initiate random access and / or data retransmission to the communication device, thereby improving the access success rate and / or data transmission success rate of the AIoT device. Based on this, in one embodiment, the method further includes:

[0148] Send a second message; among which,

[0149] The second information indicates the fallback timing for the AIoT device. The second information is used by the AIoT device to re-initiate random access and / or data retransmission to the communication device after one or more access opportunities or time intervals.

[0150] Here, the communication device can send the second information or send the second information to the AIoT device using unicast, multicast, or broadcast. The second information can be understood as a backoff indication. There can be one or more second messages. The second information can indicate when the AIoT device can re-initiate random access and / or data retransmission to the communication device after one or more access opportunities or time intervals; the second information can also indicate when the AIoT device can re-initiate random access and / or data retransmission to the communication device after one or more access opportunities or time intervals.

[0151] To improve the flexibility of AIoT devices re-initiating random access or data retransmission after access failure or data transmission failure, in one embodiment, the second information includes one or more of the following:

[0152] One access round;

[0153] Multiple access rounds;

[0154] One paging round;

[0155] Multiple paging rounds;

[0156] The third information indicates the energy status or energy level corresponding to the paging round and / or access round.

[0157] Here, a paging round can contain multiple access rounds, and an access round can contain multiple access opportunities.

[0158] For example, the second information may indicate that after paging round B1, or after access round B2, or after access opportunity B3, or after time interval T0, there is an opportunity to re-initiate random access and / or data retransmission to the communication device.

[0159] It should be noted that, if the total number of paging rounds and access rounds is greater than 1, or if the number of second information entries is greater than 1, the second information may include the third information; the third information can be understood as an energy indicator. The third information can be used to group AIoT devices to achieve collision avoidance.

[0160] Considering that the amount of data transmitted from AIoT devices to communication devices may be large, it is necessary to segment the data for transmission. The communication device can instruct the data to be segmented based on the energy state or energy level of the AIoT device to improve data transmission efficiency and success rate. Based on this, in one embodiment, the method further includes:

[0161] Send the fourth message; among which,

[0162] The fourth piece of information indicates the correspondence between the number of segments and the energy state or energy level when the AIoT device sends data to the communication device.

[0163] Here, the communication device can send the fourth information or send the fourth information to the AIoT device using unicast, multicast, or broadcast methods. The fourth information may include the correspondence between segmentation indication and energy state, and / or the correspondence between segmentation indication and energy level; the segmentation indication may indicate one or more of the following: the number of data segments, the maximum number of segments, and the minimum number of segments.

[0164] To facilitate AIoT devices in determining the method of transmitting data to communication devices, thereby improving data transmission efficiency and success rate, in one embodiment, the fourth information includes one or more of the following:

[0165] The correspondence between the number of segments and the energy state or energy level;

[0166] The correspondence between the maximum number of segments and the energy state or energy level;

[0167] The correspondence between the minimum number of segments and the energy state or energy level.

[0168] To facilitate uplink scheduling of AIoT devices based on proximity information and improve the access success rate and data transmission success rate of AIoT devices, in one embodiment, the method further includes:

[0169] Send a fifth message; wherein the fifth message indicates at least the distance or range between the AIoT device and the communication device.

[0170] Here, communication devices can send the fifth information or send the fifth information to AIoT devices using unicast, multicast, or broadcast methods. The fifth information can be understood as a proximity indicator, which can be near or far, or it can be a level of proximity information. For example, D0 indicates 0-2 meters (m), D1 indicates 2-10 meters, and D2 indicates more than 10 meters.

[0171] To facilitate data segmentation by AIoT devices, the fifth piece of information may also carry a segmentation indication. Based on this, in one embodiment, the fifth piece of information further indicates one or more of the following: the number of segments, the maximum number of segments, and the minimum number of segments.

[0172] Correspondingly, this disclosure also provides a device scheduling method applied to AIoT devices. As shown in Figure 3, the method includes:

[0173] Step 301: Receive the first message.

[0174] The first information indicates the access round and / or access opportunity for the AIoT device to initiate AIoT random access to the communication device, and corresponds to the energy state or energy level of the AIoT device.

[0175] To facilitate AIoT devices initiating random AIoT access to communication devices and improve the success rate of AIoT devices accessing communication devices, in one embodiment, the first information includes one or more of the following:

[0176] One or more access rounds;

[0177] Access opportunities included in each of one or more access rounds;

[0178] The correspondence between the energy state or energy level of AIoT devices and the access rounds and / or access opportunities.

[0179] To improve the efficiency of AIoT devices initiating random AIoT access to communication devices, in one embodiment, the correspondence between the energy state or energy level of the AIoT device and the access round and / or access opportunity indicates one or more of the following:

[0180] In the first N access rounds, AIoT devices with the Nth energy state or energy level are allowed to access or re-access, where N is a positive integer;

[0181] In the first N access rounds, at most N AIoT devices with different energy states or energy levels are allowed to access or re-access, where N is a positive integer;

[0182] The first M access opportunities in an access round allow the Mth AIoT device with the Mth energy state or energy level to access or re-access, where M is a positive integer;

[0183] The first M access opportunities in an access round allow at most M AIoT devices with different energy states or energy levels to access or re-access, where M is a positive integer.

[0184] In one embodiment, the method further includes:

[0185] Based on the first information, select the access round and / or access opportunity to initiate AIoT random access to the communication device.

[0186] Here, the AIoT device determines the access round and / or access opportunity for initiating AIoT random access to the communication device based on the first information, and the correspondence between the AIoT device's energy state or energy level and the access round and / or access opportunity that matches the AIoT device's energy state or energy level. Among the determined access rounds and / or access opportunities, the device selects the access round and / or access opportunity for initiating AIoT random access to the communication device, and initiates AIoT random access to the communication device in the selected access round and / or access opportunity.

[0187] For example, if the first information includes access round 1 and access round 2, each access includes four access opportunities: 01, 02, 03, and 04. AIoT devices 1-7 receive the first information, and their corresponding energy levels are E1, E0, E0, E1, E2, E2, and E2, respectively. AIoT devices 1-7 select the access round and / or access opportunity to initiate AIoT random access to the communication device according to their own energy level.

[0188] For example, if the first information includes access round 1 and energy level E1; access round 2 and default (default energy state or energy level); then any AIoT device 1-4, upon receiving the first information, will send a D2R message or initiate AIoT random access to the communication device at any access opportunity in access round 1; any AIoT device 5-7, upon receiving the first information, will send a D2R message or initiate AIoT random access to the communication device at any access opportunity in access round 2; AIoT device 1 and AIoT device 4 will re-initiate AIoT random access to the communication device at any access opportunity in access round 2.

[0189] Considering the possibility of AIoT devices failing to send data to the communication device or failing to access the device, requiring the AIoT device to roll back, the communication device can indicate the rollback timing to the AIoT device. This provides a more reasonable charging time for the AIoT device that has failed to access or send data, enabling it to re-initiate random access and / or data retransmission, thereby improving the access success rate and / or data transmission success rate of the AIoT device. Based on this, in one embodiment, the method further includes:

[0190] Receive the second message; among which,

[0191] The second information indicates the fallback timing for the AIoT device. The second information is used by the AIoT device to re-initiate AIoT random access and / or data retransmission to the communication device after one or more access opportunities or time intervals.

[0192] To improve the flexibility of AIoT devices re-initiating random access or data retransmission after access failure or data transmission failure, in one embodiment, the second information includes one or more of the following:

[0193] One access round;

[0194] Multiple access rounds;

[0195] One paging round;

[0196] Multiple paging rounds;

[0197] The third information indicates the energy status or energy level corresponding to the paging round and / or access round.

[0198] In one embodiment, the method further includes:

[0199] After the first access round, AIoT random access and / or data retransmission are re-initiated to the communication device; wherein,

[0200] The first access round is determined based on the second information, or based on the second information and the energy state or energy level of the AIoT device.

[0201] Here, the AIoT device receives second information. In the event of a failure to access the communication device or a failure to send data to the communication device, it determines the first access round based on the second information, or based on the second information and the AIoT device's energy state or energy level. After the first access round, it re-initiates AIoT random access and / or data retransmission to the communication device. Specifically, if the second information does not include third information, the first access round is determined based on the second information; if the second information includes third information, the first access round is determined based on the second information and the AIoT device's energy state or energy level.

[0202] For example, suppose the second information indicates that after paging round B1, or after access round B2, or after access timing B3, or after time interval T0, there is an opportunity to re-initiate random access and / or data retransmission to the communication device; if the second information does not include the third information, then when the AIoT device receives the second information, the first access round determined according to the second information can be any of the following: paging round B1, access round B2, access timing B3, or access round corresponding to time interval T0. That is, the AIoT device can send a first message to the communication device after paging round B1, after access round B2, after access timing B3, or after time interval T0 to re-initiate AIoT random access and / or data retransmission.

[0203] If the second information includes the third information, then the AIoT device, based on the third information and its own energy state or energy level, selects paging round B1, access round B2, or access timing B3 or time T0, and then sends the first message to the communication device to re-initiate AIoT random access and / or data retransmission. The first message includes, but is not limited to, one or more of the following: the third AIoT random access message Msg3, the instruction feedback message, the first AIoT random access message Msg1, and MsgA.

[0204] For example, the second information includes paging round 2, paging round 3, the energy level corresponding to paging round 2 is E1, and the energy level corresponding to paging round 3 is E2. If the current energy level of the AIoT device is E1, then the AIoT device chooses to re-initiate AIoT random access and / or data retransmission to the communication device after paging round 2, such as sending the first message and / or D2R message.

[0205] Considering that the amount of data transmitted from AIoT devices to communication devices may be large, it is necessary to segment the data for transmission. The communication device can instruct the data to be segmented based on the energy state or energy level of the AIoT device to improve data transmission efficiency and success rate. Based on this, in one embodiment, the method further includes:

[0206] Receive the fourth message; among which,

[0207] The fourth piece of information indicates the correspondence between the number of segments and the energy state or energy level when the AIoT device sends data to the communication device.

[0208] To facilitate AIoT devices in determining the method of transmitting data to communication devices, thereby improving data transmission efficiency and success rate, in one embodiment, the fourth information includes one or more of the following:

[0209] The correspondence between the number of segments and the energy state or energy level;

[0210] The correspondence between the maximum number of segments and the energy state or energy level;

[0211] The correspondence between the minimum number of segments and the energy state or energy level.

[0212] In one embodiment, the method further includes:

[0213] The first data is segmented according to the fourth information to obtain multiple data fragments of the first data.

[0214] The plurality of data segments of the first data are sent to the communication device.

[0215] Here, the AIoT device determines the correspondence between the number of segments and the energy state or energy level based on the fourth information; based on this correspondence, it determines the number of segments that match the energy state or energy level of the AIoT device; it segments the first data according to the determined number of segments and sends all data fragments of the first data to the communication device. The first data generally refers to the data sent by the AIoT device to the communication device.

[0216] To facilitate uplink scheduling of AIoT devices based on proximity information and improve the access success rate and data transmission success rate of AIoT devices, in one embodiment, the method further includes:

[0217] Receive the fifth message; among which,

[0218] The fifth piece of information at least indicates the distance or range between the AIoT device and the communication device.

[0219] To facilitate data segmentation by AIoT devices, the fifth piece of information may also carry a segmentation indication. Based on this, in one embodiment, the fifth piece of information further indicates one or more of the following: the number of segments, the maximum number of segments, and the minimum number of segments.

[0220] To improve the access success rate and data transmission success rate of AIoT devices, in one embodiment, the method further includes one or more of the following:

[0221] Based on the fifth piece of information, it is decided not to segment the second data;

[0222] The second data is segmented according to the fifth information;

[0223] The second data is segmented based on the fifth information and the energy state or energy level of the AIoT device;

[0224] Send the second data to the communication device;

[0225] Each data segment of the second data is sent to the communication device.

[0226] Here, if the fifth information does not indicate the number of segments, the maximum number of segments, or the minimum number of segments, the AIoT device decides whether to segment the second data based on the received fifth information, or based on the fifth information and the AIoT device's energy state or energy level. The second data generally refers to the data sent by the AIoT device to the communication device; the second data may be the same as or different from the first data. If the AIoT device does not segment the second data, it sends the second data to the communication device; if the AIoT device segments the second data, it sends each data segment of the second data to the communication device.

[0227] When the fifth information indicates one or more of the number of segments, the maximum number of segments, and the minimum number of segments, the AIoT device segments the second data according to the received fifth information and the AIoT device's energy state or energy level. Specifically, when the fifth information indicates the number of segments, the AIoT device segments the second data according to the number of segments indicated by the fifth information; when the fifth information indicates the maximum number of segments, the AIoT device segments the second data according to the maximum number of segments indicated by the fifth information based on the AIoT device's energy state or energy level, and the total number of data segments in the second data is less than or equal to the maximum number of segments; when the fifth information indicates the minimum number of segments, the second data segments the second data according to the minimum number of segments indicated by the fifth information based on the AIoT device's energy state or energy level, and the total number of data segments in the second data is greater than or equal to the minimum number of segments.

[0228] For example, a communication device sends a read command to AIoT device 1. The communication device, based on network inventory cooperation and proximity determination, determines that its distance to AIoT device 1 is 4 meters. In the read command message, the communication device includes fifth information indicating the AIoT device's 4-meter distance, such as a proximity indicator of D2, and a minimum segment size of 3 and a maximum segment size of 7. Upon receiving the read command message, AIoT device 1 determines that the second data to be transmitted is 1000 bits. Given that AIoT device 1 has 8J of available energy, which is considered a large quantity to be transmitted and has good energy storage, AIoT device 1 determines the number of segments for the second data to be 6; it then divides the second data into 6 data segments and sends these 6 data segments to the communication device.
