Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0135] In today's IoT networks, traditional IoT devices are typically powered by conventional batteries with limited lifespans, negatively impacting user experience. The astronomical growth of IoT networks, coupled with the sheer number of IoT devices, has pushed maintenance costs, including labor and battery expenses, to unprecedented levels. Billions of conventional batteries are discarded annually, with only a fraction being effectively recycled, causing harmful impacts on the Earth's ecosystem. Maintaining IoT networks and replacing batteries can be extremely challenging under some extreme environmental conditions. In this regard, battery-free IoT communication has been proposed, which will improve network performance and sustainability and expand application scenarios. Furthermore, battery-free communication is more environmentally friendly and safer for children and the elderly. By eliminating conventional batteries, device size and cost can be significantly reduced, paving the way for a variety of new applications.

[0136] In the 5G era, various low-power wide-area (LPWA) technologies have been developed, such as machine-type communication (MTC), narrowband internet of things (NB-IoT), and reduced capability (RedCap), to meet the growing demands of vertical industries. These LPWA technologies achieve low cost, low power consumption, and massive connectivity, satisfying the requirements of many applications. However, many use cases and applications remain unresolved in the following situations: First, devices powered by traditional batteries are unsuitable, for example, under extreme environmental conditions (e.g., high voltage, extremely high / low temperatures, humid environments). Second, maintenance-free devices are required (e.g., traditional batteries that do not require replacement). Finally, ultra-low complexity, very small device size / form factor (e.g., thickness in millimeters), and longer lifespan are needed.

[0137] Ambient power-enabled IoT is a promising technology that can address the aforementioned unmet needs. An ambient power-enabled IoT device is an IoT device powered by energy harvesting, without batteries or with limited energy storage capacity (e.g., using capacitors), providing energy by harvesting radio waves, light, motion, heat, or any other suitable source.

[0138] Energy harvested from the environment can power data transmission and wireless communication at sensing nodes. Current mainstream low-power IoT communication chips (such as Bluetooth Low Energy (BLE), LoRa, and NB-IoT) consume tens or even hundreds of milliwatts of power for transmission and reception, while environmental energy harvesting yields only microwatts, insufficient to power these types of nodes. Therefore, a new wireless communication technology is needed to reduce communication energy consumption to tens or even below ten microwatts. Currently, the mainstream approach uses backscatter communication technology. Backscatter communication is one of the key technologies for building a green, energy-efficient, low-cost, and flexibly deployable future Internet of Things (IoT), and is an important means of realizing "intelligent interconnection of everything."

[0139] Backscatter communication utilizes the principle of radio frequency signal backscattering to design an extremely low-power modulation and transmission technology. First proposed by Stockman, backscatter communication works by reflecting a portion of the radio frequency signal as it reaches the surface of an object. The transmitting node adjusts the matching between its receiving antenna and impedance according to the information to be transmitted, enhancing the reflection of the incident radio frequency signal and modulating its acquired sensing data onto the reflected signal to complete the data transmission. This process is analogous to a reflector. Compared to other communication technologies, backscatter communication does not require complex radio frequency structures, reducing the use of components such as power amplifiers, high-precision crystal oscillators, duplexers, and high-precision filters. It also does not require complex baseband processing, thus simplifying terminal design and significantly reducing the cost of terminal nodes.

[0140] Backscatter communication has been widely used in radio frequency identification (RFID) systems, resulting in many large-scale commercial applications. Its working principle is that a receiver (typically an RFID reader) sends a radio frequency excitation signal to activate a passive node (typically an RFID tag). The tag uses backscatter communication to modulate its own information onto the radio frequency signal. The reader receives the reflected signal from the passive tag and demodulates it to achieve information transmission.

[0141] Currently, RFID technology also has many drawbacks, such as short coverage distance (the wireless signal experiences double-path fading during communication, resulting in significant path loss and a short effective communication distance), single-channel transmission, the need for strict tag alignment, and lack of power control. There is significant room for improvement in the communication aspects of RFID technology. Integrating 3GPP communication technologies is needed to improve the wireless communication performance of RFID technology in passive IoT applications.

[0142] Our target new type of IoT device features low memory, low processing power, low power consumption, small data transmission, and mass deployment. Environmental IoT devices can be maintenance-free and have a long lifespan (e.g., over 10 years).

[0143] This new type of IoT device requires energy from radio waves emitted by network nodes to power itself. Therefore, before receiving energy, the IoT device is typically in a "power-off" state, i.e., offline. For this reason, the communication system needs to support data communication methods with shorter transmission times, lower memory consumption, and more convenient terminal management to complete the data communication process as quickly as possible.

[0144] In some embodiments, AIoT devices can be categorized into three types. The first type of AIoT device has neither energy storage capability nor independent signal generation capability. The second type of AIoT device has energy storage capability but lacks independent signal generation capability. The third type of AIoT device has both energy storage capability and independent signal generation capability. For the first and second types of AIoT devices, signals can be generated through backscattering.

[0145] In some embodiments, multiple connection topologies exist based on AIoT devices. Figures 2A to 2D are schematic diagrams of AIoT-based connection topologies. As shown in Figures 2A to 2D, AIoT-based devices can typically have four different connection topologies.

[0146] In some embodiments, as shown in FIG2A, the first connection topology (or Topology 1, first type of topology) can be: base station <—> AIoT device. In some embodiments, the AIoT device can directly communicate bidirectionally with the base station. The communication between the base station and the AIoT device can include data and / or signaling related to AIoT services. In the first connection topology, the transmission from the base station to the AIoT device and the transmission from the AIoT device to the base station can be the same or different.

[0147] In some embodiments, as shown in Figure 2B, the second connection topology (or Topology 2, second type of topology) can be: base station <—> intermediate node <—> AIoT device. In some embodiments, user equipment (UE) can be used as an intermediate node under network control. In some embodiments, the AIoT device can communicate bidirectionally with the intermediate node located between the AIoT device and the base station. The intermediate node can be a relay with AIoT capabilities, an integrated access and backhaul (IAB) node, a UE, a repeater, etc. The intermediate node can forward information between the base station and the AIoT device.

[0148] In some embodiments, as shown in Figure 2C, the third connection topology (or Topology 3, Third Type Topology) can be: Base Station <—> Auxiliary Node <—> AIoT Device <—> Base Station. In some embodiments, the AIoT device can send data and / or signaling to the base station and can receive data and / or signaling from the auxiliary node. In some embodiments, the AIoT device can receive data and / or signaling from the base station and can send data and / or signaling to the auxiliary node. In this topology, the auxiliary node can be a relay, integrated access and backhaul node, UE, repeater, etc., with AIoT capabilities.

[0149] In some embodiments, as shown in FIG2D, the fourth link topology (or topology 4, fourth type of topology) can be: UE <—> AIoT device. In some embodiments, the AIoT device can communicate bidirectionally with the UE. In some embodiments, the communication between the AIoT device and the UE may include data and / or signaling of the AIoT service.

[0150] In different connection topologies, readers can be implemented by different types of devices. For example, a reader can be a base station, an intermediate node, a UE, etc.

[0151] The latest RAN plenary meeting concluded that R19 supports both Topology 1 and Topology 2. In some embodiments, in deployment scenarios using Topology 1, the base station and coexistence characteristics are: microcell, co-located. In some embodiments, in deployment scenarios using Topology 2, and where the UE acts as an intermediate node under network control, the base station and coexistence characteristics are: macrocell, co-located; and the intermediate node is located indoors.

[0152] In passive IoT systems, terminal data transmission occurs in three types: DO-DTT, DT, and DO-A. DO-DTT (device-originated, device-terminated, triggered) can be data triggered by a reader / writer, such as during inventory. DT (device-terminated) can be access commands, for example. DO-A (device-originated, autonomous) can be data actively transmitted by tags, such as proactive reporting triggered by sensor functions.

[0153] In existing standards, the first message that triggers initial access for a device can be called a paging message or an "initial trigger message." A paging message can page one, a group, or all IoT devices. If a paging message pages a single IoT device, it triggers non-contention-based random access. The paged IoT device responds to the paging message on non-contention-based resources, for example, by sending an acknowledgment (ACK) message containing the IoT device's identifier, such as an electronic product code (EPC). If a paging message triggers a group or all IoT devices, it triggers contention-based random access. The paged group or all IoT devices generate a random number based on a parameter similar to Q, and then continue to receive query messages / queryadjust messages / queryrep messages until the random number decreases to 0, at which point they initiate random access again, for example, by sending the generated random number.

[0154] Due to limitations in storage power and scheduling resources, device-to-reader (D2R) messages sent by IoT devices may need to be segmented. RAN2 has discussed how to support segmentation, with the following conclusions. The D2R message most likely to require segmentation is the response message to a "read command." A read command is used to retrieve a portion of data from the IoT device's memory; therefore, the response message to this command is a segment of the data that was read. For low-capacity IoT devices, when segmentation is determined to be necessary, the information that needs to be cached in the temporary buffer, how to use this information for segmented new transmission or retransmission, and the specific actions for updating this information need to be clearly defined.

[0155] Therefore, how to achieve segmented transmission of D2R messages is a technical problem that urgently needs to be solved.

[0156] Figure 3 is an interactive schematic diagram of the communication method provided according to an embodiment of the present disclosure. The communication method involved in the embodiment of the present disclosure can be applied to the communication system 100. As shown in Figure 3, the communication method of the embodiment of the present disclosure includes steps S301 to S311.

[0157] In step S301, the second node 102 sends a first command message to the first node 101.

[0158] In some embodiments, the second node 102 may send a first command message. In some embodiments, the first command message may be sent by the second node 102, but is not limited thereto, and may also be sent by other entities.

[0159] In some embodiments, the first node 101 may receive a first command message. In some embodiments, the first command message may be received by the first node 101, but is not limited thereto, and may also be received by other entities.

[0160] In some embodiments, the first command message can be used to instruct the first node 101 to perform an operation. In some embodiments, the first command message can be used to trigger the first node 101 to implement an AIoT service.

[0161] In some embodiments, an AIoT service may include at least one of the following: inventory and command. In some embodiments, a command may include at least one of the following: read, write, and disable. It is understood that an AIoT service may also have other types, and this disclosure does not specifically limit these types.

[0162] In some embodiments, the first command message may be a read request message. In one example, the first command message may include a read command for reading data from the first node 101. It is understood that the first command message may also be used to instruct the first node 101 to perform other operations, which are not specifically limited in this disclosure.

[0163] In some embodiments, the first command message may include at least one of the following: identification information of the first node 101 and first resource information.

[0164] In some embodiments, the identification information of the first node 101 can be used to indicate the target of the first command message. In some embodiments, the first node 101 indicated by the identification information may be the first node 101 to which the first command message is targeted.

[0165] In some embodiments, the identification information of the first node 101 may include at least one of the following: temporary identifier, electronic product code, or device identifier.

[0166] In some embodiments, a temporary identifier can be used to uniquely identify the first node 101 within the coverage area of ​​the second node 102. In some embodiments, the temporary identifier can be an identifier assigned by the second node 102 to the first node 101. In some embodiments, the temporary identifier can be an identifier determined by the first node 101. For example, the first node 101 carries a 16-bit random number in message 1 (Msg1) during the random access procedure. It is understood that the temporary identifier can also have any number of bits, and this disclosure does not specifically limit this.

[0167] In some embodiments, the electronic product code can be used to uniquely identify the first node 101 globally.

[0168] In some embodiments, the device identifier may be assigned to the first node 101 by the core network or a third party. For example, the device identifier may be assigned by the owner of the first node 101. For example, the device identifier may be assigned by the manufacturer of the first node 101. For example, the device identifier may be assigned by the user of the first node 101.

[0169] In some embodiments, the identification information of the first node 101 carried in the first command message can be stored in the first node 101. For example, the first node 101 can store a temporary identifier of the first node 101.

[0170] In some embodiments, the first resource information can be used to indicate a first resource for the first node 101 to send a second message. For example, the first resource may include time-domain resources and / or frequency-domain resources. In some embodiments, the first resource information can be used to indicate a first resource that can be used by the first node 101 to send a second message. In some embodiments, the first resource may be determined by the second node 102, in which case the second node 102 can indicate the first resource to the first node 101 through the first resource information.

[0171] In step S302, the first node 101 performs an operation.

[0172] In some embodiments, the first node 101 may perform operations related to the first command message.

[0173] In some embodiments, when the first command message is a read request message, the first node 101 can perform a read operation based on the first command message to determine the data to be sent to the second node 102. In one example, the first node 101 may be a sensor-type device. In this case, the first node 101 may determine to send locally stored sensing data to the second node 102, or the first node 101 may perform a sensing operation and acquire sensing data.

[0174] In some embodiments, when performing an operation related to the first command message, the first node 101 may determine the second message.

[0175] In some embodiments, the second message may be a response message determined by the first node 101 in response to the first command message. In some embodiments, the second message may include data that the first node 101 needs to send to the second node 102.

[0176] In some embodiments, the second message may be stored in the first node 101. In some embodiments, the second message determined by the first node 101 may be stored in the storage space of the first node 101.

[0177] In step S303, the first node 101 determines the first message.

[0178] In some embodiments, the first node 101 may determine whether to send the second message in segments.

[0179] In some embodiments, step S303 may include: determining to segment the second message. In some embodiments, when determining the second message, the first node 101 may determine to segment the second message.

[0180] In some embodiments, the first node 101 may determine to segment the second message based on the first resource and / or the power status of the first node 101. In some embodiments, if the first node 101 determines that the first resource is insufficient to complete the transmission of the second message, then the first node 101 may determine to segment the second message. For example, if the first node 101 determines that the resources required to send the second message exceed the first resource indicated by the first resource information, then the first node 101 may determine to segment the second message. In some embodiments, if the first node 101 determines that its own power is insufficient to complete the transmission of the second message, then the first node 101 may determine to segment the second message. For example, if the first node 101 determines that the message length it can send with its own power is less than the length of the second message, then the first node 101 may determine to segment the second message. In some embodiments, if the first node 101 determines that both the first resource and the first node 101's power are insufficient to complete the transmission of the second message, then the first node 101 may determine to segment the second message.

[0181] In some embodiments, if the first node 101 determines that the first resources are sufficient to complete the transmission of the second message and the first node 101 has sufficient power to complete the transmission of the second message, the first node 101 may determine not to segment the second message.

[0182] In some embodiments, step S303 may further include: determining a first message. In some embodiments, when it is determined that the second message will be segmented, the first node 101 may determine the first message. The first message may be the first segment in the second message.

[0183] In some embodiments, the first node 101 may determine the first message based on the first resource and / or the power status of the first node 101. In some embodiments, the first node 101 may determine the length of the first message based on the first resource and / or the power status of the first node 101.

[0184] In some embodiments, the first node 101 can determine the first message based on the first resource. In one example, the first node 101 can determine the length of the first message based on the first resource indicated by the first resource information. Then, the first node 101 can determine the first message with that length from the second message.

[0185] In some embodiments, the first node 101 can determine the first message based on its battery status. In one example, the first node 101 can determine the length of the first message based on its battery status. Then, the first node 101 can determine the first message of that length from a second message.

[0186] In some embodiments, the first node 101 can determine the first message based on the first resource and the power status of the first node 101. In one example, the first node 101 can determine the length of the first message based on the first resource and the power status of the first node 101. Then, the first node 101 can determine the first message with that length from the second message.

[0187] In some embodiments, the length of the first message can be an integer multiple of bytes. For example, the length of the first message can be equal to 8 × N1 bits. Here, N1 is a positive integer.

[0188] In some embodiments, the length of the first message can be an integer multiple of two bytes. For example, the length of the first message can be equal to 16 × N² bits. Here, N² is a positive integer.

[0189] In some embodiments, the length of the first message can be any number of bits. In this case, the length of the first message does not necessarily have to be an integer multiple of bytes or double bytes.

[0190] In some embodiments, the length of the first message does not exceed the size of the first resource. In some embodiments, the number of bits in the first message may be less than or equal to the size of the first resource. In one example, the number of bits in the first message may be less than or equal to the transport block size (TBS) of the first resource. In some embodiments, the transport block size of the first resource may not be an integer multiple of bytes. In this case, the number of bits in the first message, which is an integer multiple of bytes in length, may be less than the transport block size of the first resource.

[0191] In step S304, the first node 101 stores location information.

[0192] In some embodiments, the location information stored in the first node 101 may include the location information of the first message and / or the location information of the second message.

[0193] In some embodiments, the location information of the first message may indicate the location of the first message in the storage space of the first node 101.

[0194] In some embodiments, the location information of the first message may indicate at least one of the following: the start position of the first message, the end position of the first message, and the length of the first message.

[0195] In some embodiments, the starting position of the first message can be the starting position of the first message in the storage space of the first node 101. For example, the starting position of the first message can be the starting address of the storage space occupied by the first message. In some embodiments, the location information stored in the first node 101 can include the starting address of the storage space occupied by the first message.

[0196] In some embodiments, the end position of the first message can be the end position of the first message in the storage space of the first node 101. For example, the end position of the first message can be the end address of the storage space occupied by the first message. In some embodiments, the location information stored by the first node 101 can include the end address of the storage space occupied by the first message.

[0197] In some embodiments, the length of the first message can be the number of bits of the first message in the storage space of the first node 101. For example, the length of the first message can be the length between the start address and the end address of the storage space occupied by the first message.

[0198] In some embodiments, the length of the first message can be an integer multiple of bytes. In some embodiments, the location information stored by the first node 101 can include N1, i.e., a multiple of bytes. In one example, the location information stored by the first node 101 can include the number of bytes between the start and end addresses of the storage space occupied by the first message.

[0199] In some embodiments, the length of the first message can be an integer multiple of two bytes. In some embodiments, the location information stored in the first node 101 can include N2, i.e., a multiple of two bytes. In one example, the location information stored in the first node 101 can include the number of two bytes between the start and end addresses of the storage space occupied by the first message.

[0200] In some embodiments, the location information stored by the first node 101 may be the number of bits in the first message. In one example, the location information stored by the first node 101 may include the number of bits between the start and end addresses of the storage space occupied by the first message.

[0201] In some embodiments, the location information of the second message may indicate the location of the second message in the storage space of the first node 101.

[0202] In some embodiments, the location information of the second message may indicate at least one of the following: the start position of the second message, the end position of the second message, and the length of the second message.

[0203] In some embodiments, the starting position of the second message can be the starting position of the second message in the storage space of the first node 101. For example, the starting position of the second message can be the starting address of the storage space occupied by the second message. In some embodiments, the location information stored in the first node 101 can include the starting address of the storage space occupied by the second message.

[0204] In some embodiments, the end position of the second message can be the end position of the second message in the storage space of the first node 101. For example, the end position of the second message can be the end address of the storage space occupied by the second message. In some embodiments, the location information stored by the first node 101 can include the end address of the storage space occupied by the second message.

[0205] In some embodiments, the length of the second message can be the number of bits of the second message in the storage space of the first node 101. For example, the length of the second message can be the length between the start address and the end address of the storage space occupied by the second message.

[0206] It is understandable that the storage space occupied by the second message can cover the storage space occupied by the first message. In other words, the storage space where the first message is located can be a part of the storage space where the second message is located. As the first segment of the second message, the starting position of the first message can be the same as the starting position of the second message.

[0207] In some embodiments, the location information of the first message and the location information of the second message can be stored in volatile memory. Of course, the location information of the first message and the location information of the second message can be stored in non-volatile memory or other types of memory, and this disclosure does not specifically limit this.

[0208] In step S305, the first node 101 sends a first message to the second node 102.

[0209] In some embodiments, the first node 101 may send a first message. In some embodiments, the first message may be sent by the first node 101, but is not limited to this, and may also be sent by other entities.

[0210] In some embodiments, the second node 102 may receive the first message. In some embodiments, the first message may be received by the second node 102, but is not limited thereto, and may also be received by other entities.

[0211] In some embodiments, the first message may be sent by the first node 101 to the second node 102 as a response message to the first command message.

[0212] In some embodiments, the length of the first message may be less than or equal to the size of the first resource. In some embodiments, the first node 101 may send the first message to the second node 102 through the first resource.

[0213] In some embodiments, the length of the first message may be an integer multiple of two bytes, and the size of the first resource may not be an integer multiple of two bytes. In this case, the length of the first message may be less than the size of the first resource. The first node 101 may carry the first message in the first resource and pad the resources in the first resource that do not carry the first message.

[0214] In some embodiments, the length of the first message may be an integer multiple of bytes, and the size of the first resource may not be an integer multiple of bytes. In this case, the length of the first message may be less than the size of the first resource. The first node 101 may carry the first message in the first resource and fill in any resources in the first resource that do not carry the first message.

[0215] In some embodiments, the padding method may include: zero padding, random padding, and specific value padding. In one example, with zero padding, the first node 101 may add a bit with a value of 0 to the end of the data block of the first resource. In one example, with random padding, the first node 101 may add a randomly generated bit to the end of the data block of the first resource. In one example, with specific value padding, the first node 101 may add a specific value, such as a bit with a value of 1, to the end of the data block of the first resource.

[0216] In some embodiments, step S305 may include: the first node 101 sending second information to the second node 102.

[0217] In some embodiments, the second information may be used to indicate whether the second message has been fully sent. In some embodiments, the second information may be used to indicate whether the first node 101 has completed sending the second message. In some embodiments, the second information may be used by the second node 102 to determine whether the complete second message has been received.

[0218] In some embodiments, the second information may include at least one of the following: first indication information and remaining quantity information.

[0219] In some embodiments, the first indication information can be used to indicate whether the first message is the last segment in the second message. In some embodiments, the first indication information can indicate that the first message is the last segment by a first value, and can indicate that the first message is not the last segment by a second value. In one example, the first indication information may include a bit. When the value of the bit is 1, the first indication information can indicate that the first message is the last segment; when the value of the bit is 0, the first indication information can indicate that the first message is not the last segment. In one example, when the value of the bit is 0, the first indication information can indicate that the first message is the last segment; when the value of the bit is 1, the first indication information can indicate that the first message is not the last segment. In some embodiments, the first indication information may only have the first value. For example, when the second information includes the first indication information, the first indication information with the first value can indicate that the first message is the last segment; when the second information does not include the first indication information, the first message may be implicitly indicated as not being the last segment. In some embodiments, the first indication information may only have the second value. For example, when the second information includes the first indication information, the first indication information with a second value can indicate that the first message is not the last segment; when the second information does not include the first indication information, the first message can be implicitly indicated as the last segment.

[0220] In some embodiments, the remaining quantity information can be used to indicate the amount of data not sent in the second message. In some embodiments, the remaining quantity information can indicate the length of the remaining content in the second message after the first message has been sent. In some embodiments, the remaining quantity information can indicate the number of bits of data not sent in the second message. In some embodiments, the remaining quantity information can indicate the number of bytes of data not sent in the second message. For example, the remaining quantity information can indicate an integer N3, indicating that the amount of data not sent in the second message is N3 bytes. In some embodiments, the remaining quantity information can indicate the number of double bytes of data not sent in the second message. For example, the remaining quantity information can indicate an integer N4, indicating that the amount of data not sent in the second message is N4 double bytes.

[0221] In some embodiments, the first message sent in step S305 is not the last segment of the second message. In one example, the second information may only include the first indication information. For example, the first indication information in the second information may have a second value to indicate that the first message is not the last segment of the second message. In one example, the second information may include the first indication information and remaining amount information. The first indication information may have a second value to indicate that the first message is not the last segment of the second message. The remaining amount information may indicate the amount of data not sent. In one example, the second information may only include the remaining amount information. When the amount of unsent data indicated by the remaining amount information in the second information is greater than 0, the first node 101 can implicitly indicate through the remaining amount information that the first message is not the last segment of the second message.

[0222] In some embodiments, the second information may be sent to the second node 102 along with the first message. In some embodiments, the second information may be sent to the second node 102 after or before the first message.

[0223] In step S306, the second node 102 sends the first information to the first node 101.

[0224] In some embodiments, the second node 102 may send the first information. In some embodiments, the first information may be sent by the second node 102, but is not limited thereto, and may also be sent by other entities.

[0225] In some embodiments, the first node 101 may receive the first information. In some embodiments, the first information may be received by the first node 101, but is not limited thereto, and may also be received by other entities.

[0226] In some embodiments, the second node 102 may determine that the transmission of the second message is incomplete. If the complete second message is not received, the second node 102 may send the first message to the first node 101.

[0227] In some embodiments, the second node 102 can determine that the received first message is not the last segment in the second message based on the previously received second information. For example, the second node 102 can determine that the received first message is not the last segment based on the first indication information and / or the remaining amount information.

[0228] In some embodiments, the second node 102 may determine that reception of the first message has failed. For example, the second node 102 may not have received the first message before a timer expires. This timer may, for example, be set when the second node 102 sends the first command message.

[0229] In some embodiments, the first information can be used to instruct the first node 101 to retransmit or retransmit the message. In some embodiments, if the second node 102 determines that receiving the first message failed, the second node 102 can send the first information to instruct the first node 101 to retransmit the first message. In some embodiments, if the second node 102 determines that the received first message is not the last segment of the second message, the second node 102 can send the first information to instruct the first node 101 to retransmit the first message, i.e., to send a new first message.

[0230] In some embodiments, the first information may include at least one of the following: transmission type information and second resource information.

[0231] In some embodiments, transmission type information can be used to indicate new transmission or retransmission. In some embodiments, transmission type information can indicate new transmission by a first value and retransmission by a second value. In one example, transmission type information may include a single bit. For example, when the value of this bit is 1, the transmission type information can indicate retransmission; when the value of this bit is 0, the transmission type information can indicate new transmission.

[0232] In some embodiments, the second resource information may be used to indicate a second resource for the first node 101 to send a second message. In some embodiments, the second resource information may be used to indicate a second resource that can be used by the first node 101 to send a second message. In some embodiments, the second resource may be determined by the second node 102, in which case the second node 102 may indicate the second resource to the first node 101 through the second resource information.

[0233] In some embodiments, the second resource indicated by the second resource information can be used to implement new transmission or retransmission. In some embodiments, in the case of new transmission, the second resource indicated by the second resource information may be the same as or different from the first resource. For example, the size of the second resource may be the same as or different from the size of the first resource. In some embodiments, in the case of retransmission, the second resource indicated by the second resource information may be the same as or different from the first resource. For example, the size of the second resource may be greater than or equal to the size of the first resource.

[0234] In step S307, the first node 101 determines the first message.

[0235] In some embodiments, the first node 101 may determine the first message based on the first information.

[0236] In some embodiments, the first information may indicate a retransmission. In this case, the first node 101 may determine to retransmit the previously sent first message. For example, the first node 101 may determine to retransmit the first message sent in step S305.

[0237] In some embodiments, the first node 101 can determine the first message based on at least one of the following: the location information of the second message and the location information of the first message. In some embodiments, the first node 101 can obtain the location information of the second message and / or the location information of the first message locally, and determine the first message based on the location information of the second message and / or the location information of the first message. In one example, the first node 101 can determine the first message based on the start and end positions of the first message. In one example, the first node 101 can determine the first message based on the start position and length of the first message. In one example, the first node 101 can determine the first message based on the length and end position of the first message. In one example, the first node 101 can determine the first message based on the start position of the second message and the length and / or end position of the first message. For example, the retransmitted first message may be the first segment in the second message. In one example, the first node 101 can determine the first message based on the end position of the second message and the length and / or start position of the first message. For example, the retransmitted first message may be the last segment in the second message.

[0238] In some embodiments, the first information may indicate a new transmission. In this case, the first node 101 may determine to send a new first message. The new first message may be the next segment of the segment containing the previously sent first message. For example, the next segment of the segment corresponding to the first message sent in step S305 corresponds to the new first message.

[0239] In some embodiments, in the case of new transmission, the new first message may also be referred to as the third message.

[0240] In some embodiments, the first node 101 may determine the third message based on at least one of the following: the location information of the second message, the location information of the first message, the second resource information, and the power status of the first node 101.

[0241] In some embodiments, the first node 101 may determine the third message based on the second resource and / or the power status of the first node 101. In some embodiments, the first node 101 may determine the length of the third message based on the second resource and / or the power status of the first node 101.

[0242] In some embodiments, the first node 101 can determine the third message based on the second resource. In one example, the first node 101 can determine the length of the third message based on the second resource indicated by the second resource information. Then, the first node 101 can determine the third message with that length from the second message.

[0243] In some embodiments, the first node 101 can determine the third message based on its battery status. In one example, the first node 101 can determine the length of the third message based on its battery status. Then, the first node 101 can determine the third message of that length from the second message.

[0244] In some embodiments, the first node 101 can determine the third message based on the second resource and the power status of the first node 101. In one example, the first node 101 can determine the length of the third message based on the second resource and the power status of the first node 101. Then, the first node 101 can determine the third message with that length from the second message.

[0245] In some embodiments, the first node 101 can determine the third message based on the location information of the second message and the location information of the first message. In some embodiments, the first node 101 can determine the starting position of the next segment in the second message corresponding to the segment of the first message based on the location information of the second message and the location information of the first message. The starting position of this next segment is the starting position of the third message. The length of the third message can be determined by the first node 101 based on the second resource and / or the power status of the first node 101. It is understood that the ending position of the third message can be determined by the starting position and the length of the third message, and this ending position does not exceed the ending position of the second message. In other words, the length of the third message does not exceed the length of the remaining data in the second message.

[0246] In some embodiments, the first node 101 may determine the third message, that is, the new first message to be transmitted.

[0247] In some embodiments, the length of the third message can be an integer multiple of bytes, an integer multiple of two bytes, or any number of bits.

[0248] In some embodiments, the length of the third message does not exceed the size of the second resource. In some embodiments, the number of bits in the third message may be less than or equal to the size of the second resource. In one example, the number of bits in the third message may be less than or equal to the transport block size of the second resource. In some embodiments, the transport block size of the second resource may not be an integer multiple of bytes. In this case, the number of bits in the third message whose length is an integer multiple of bytes may be less than the transport block size of the second resource.

[0249] In step S308, the first node 101 stores location information.

[0250] The optional implementation of step S308 can be found in the optional implementation of step S304 in Figure 3, as well as other related parts in the embodiments involved in Figure 3, which will not be repeated here.

[0251] In some embodiments, when the first node 101 transmits a new message, the first node 101 may store the location information of the third message (i.e., the new first message). In one example, the first node 101 may replace the location information of the original first message with the location information of the third message. In other words, the first node 101 may update the location information of the first message.

[0252] In some embodiments, if the first node 101 performs a retransmission, the first node 101 may not perform step S308.

[0253] In step S309, the first node 101 and the second node 102 send a first message.

[0254] The optional implementation of step S309 can be found in the optional implementation of step S305 in Figure 3, as well as other related parts in the embodiments involved in Figure 3, which will not be repeated here.

[0255] In some embodiments, step S309 may include: the first node 101 sending second information to the second node 102.

[0256] In some embodiments, the second information may be used to indicate whether the second message has been fully sent. In some embodiments, the second information may be used to indicate whether the first node 101 has completed sending the second message. In some embodiments, the second information may be used by the second node 102 to determine whether the complete second message has been received.

[0257] In some embodiments, the second information may include at least one of the following: first indication information and remaining quantity information.

[0258] In some embodiments, the first indication information can be used to indicate whether the first message is the last segment in the second message. In some embodiments, the first indication information can indicate that the first message is the last segment by a first value, and can indicate that the first message is not the last segment by a second value. In one example, the first indication information may include a bit. When the value of the bit is 1, the first indication information can indicate that the first message is the last segment; when the value of the bit is 0, the first indication information can indicate that the first message is not the last segment. When the value of the bit is 0, the first indication information can indicate that the first message is the last segment; when the value of the bit is 1, the first indication information can indicate that the first message is not the last segment. In some embodiments, the first indication information may only have the first value. For example, when the second information includes the first indication information, the first indication information with the first value can indicate that the first message is the last segment; when the second information does not include the first indication information, the first message may be implicitly indicated as not being the last segment. In some embodiments, the first indication information may only have the second value. For example, when the second information includes the first indication information, the first indication information with a second value can indicate that the first message is not the last segment; when the second information does not include the first indication information, the first message can be implicitly indicated as the last segment.

[0259] In some embodiments, the remaining quantity information can be used to indicate the amount of data not sent in the second message. In some embodiments, the remaining quantity information can indicate the length of the remaining content in the second message after the first message has been sent. In some embodiments, the remaining quantity information can indicate the number of bits of data not sent in the second message. In some embodiments, the remaining quantity information can indicate the number of bytes of data not sent in the second message. For example, the remaining quantity information can indicate an integer N3, indicating that the amount of data not sent in the second message is N3 bytes. In some embodiments, the remaining quantity information can indicate the number of double bytes of data not sent in the second message. For example, the remaining quantity information can indicate an integer N4, indicating that the amount of data not sent in the second message is N4 double bytes.

[0260] In some embodiments, the first message sent in step S309 is not the last segment of the second message. In one example, the second information may only include the first indication information. For example, the first indication information in the second information may have a second value to indicate that the first message is not the last segment of the second message. In one example, the second information may include the first indication information and remaining amount information. The first indication information may have a second value to indicate that the first message is not the last segment of the second message. The remaining amount information may indicate the amount of data not sent. In one example, the second information may only include the remaining amount information. When the amount of unsent data indicated by the remaining amount information in the second information is greater than 0, the first node 101 can implicitly indicate through the remaining amount information that the first message is not the last segment of the second message.

[0261] In some embodiments, the first message sent in step S309 is the last segment of the second message. In one example, the second information may only include first indication information. For example, the first indication information in the second information may have a first value to indicate that the first message is the last segment of the second message.

[0262] In some embodiments, the second information may be sent to the second node 102 along with the first message. In some embodiments, the second information may be sent to the second node 102 after or before the first message.

[0263] In some embodiments, the first node 101 may not send the second information. The omission of the second information can be used to implicitly indicate that the first message is the last segment.

[0264] In some embodiments, the second message may be divided into two or more segments. In some embodiments, steps S306 to S309 may be repeated until the last segment of the second message is sent to the second node 102.

[0265] In step S310, the second node 102 sends a fourth message to the first node 101.

[0266] In some embodiments, the first node 101 may send a fourth message. In some embodiments, the fourth message may be sent by the first node 101, but is not limited thereto, and may also be sent by other entities.

[0267] In some embodiments, the second node 102 may receive a fourth message. In some embodiments, the fourth message may be received by the second node 102, but is not limited thereto, and may also be received by other entities.

[0268] In some embodiments, the second node 102 can determine that the transmission of the second message is complete. Upon receiving the complete second message, the second node 102 can send a fourth message to the first node 101. In some embodiments, the second node 102 can determine that the transmission of the second message is complete upon successfully receiving the first message corresponding to the last segment of the second message.

[0269] In some embodiments, the second node 102 can determine that the received first message is the last segment of the second message based on the previously received second information. In some embodiments, the second node 102 may not have received the second information while receiving the first message, in which case the second node 102 can determine that the received first message is the last segment of the second message.

[0270] In some embodiments, if it is determined that the complete second node 102 has been received, the second node 102 may send a fourth message.

[0271] In some embodiments, the fourth message may be a response message.

[0272] In some embodiments, the fourth message may be sent by the second node 102 in response to the second message. In some embodiments, the second node 102 may send the fourth message to the first node 101 after receiving the second message. In some embodiments, a response message may be used to indicate that the second node 102 has received the second message.

[0273] In some embodiments, the fourth message may be an acknowledgment message (ACK).

[0274] In some embodiments, the fourth message may be a second command message.

[0275] In some embodiments, the second node 102 may send a second command message to the first node 101 to instruct the first node 101 to perform another operation. The second command in the second command message may be different from the first command in the first command message. For example, the second command message may be used to instruct the first node 101 to perform operations such as disk storage, write, or invalidate.

[0276] In some embodiments, the fourth message may be a paging message.

[0277] In some embodiments, a paging message may include at least one of the following: a device identifier, a paging repeat identifier, and a session identifier.

[0278] In some embodiments, the device identifier carried in the paging message can be used to indicate the paged device. In some embodiments, the paging message may include one or more device identifiers or group identifiers. In some embodiments, the paging message may not carry a device identifier. For example, the paging message may be for all devices within the coverage area of ​​the second node 102.

[0279] In step S311, the first node 101 performs the first operation.

[0280] In some embodiments, the first node 101 may determine that the second message has been sent and perform the first operation.

[0281] In some embodiments, the first node 101 may determine that the second message has been sent successfully if a first condition is met. In some embodiments, the first condition may be used to determine whether the sending of the second message has been completed.

[0282] In some embodiments, the first condition may include at least one of the following: the first node 101 receives a response message from the second node 102; the first node 101 does not receive first information from the second node 102 indicating retransmission within a first time period; the first node 101 receives a paging message from the second node 102; or the first node 101 receives a second command message from the second node 102.

[0283] In some embodiments, the first node 101 may receive a fourth message from the second node 102 and determine that the second message has been sent based on the fourth message.

[0284] In some embodiments, the first node 101 may receive a response message from the second node 102, indicating that the second node 102 has received the last segment of the second message. In this case, the first node 101 can determine that the second message has been sent.

[0285] In some embodiments, if the first node 101 receives a second command message from the second node 102, the first node 101 can determine that the second message has been sent.

[0286] In some embodiments, the first node 101 may receive a paging message from the second node 102. In some embodiments, the first node 101 may determine that the second message has been sent if both the first and second conditions are met.

[0287] In some embodiments, the second condition may include at least one of the following: the first node 101 has not received the paging repeat identifier and / or session identifier carried in the paging message; the first node 101 is different from the device to which the paging message is addressed.

[0288] In some embodiments, the first node 101 may receive a paging message carrying a paging duplicate identifier and / or a session identifier. In some embodiments, if the paging duplicate identifier and / or session identifier in the paging message are not stored by the first node 101, the first node 101 may determine that the second message has been sent successfully. In one example, the paging message may carry a paging duplicate identifier, and the first node 101 may not store the paging duplicate identifier, in which case the first node 101 may determine that the second message has been sent successfully. In one example, the paging duplicate identifier stored in the first node 101 may be different from the paging duplicate identifier carried in the paging message, in which case the first node 101 may determine that the second message has been sent successfully. In one example, the session identifier stored in the first node 101 may be different from the session identifier carried in the paging message, in which case the first node 101 may determine that the second message has been sent successfully.

[0289] In some embodiments, the first node 101 may receive a paging message carrying a device identifier. The device identifier in the paging message may not indicate the first node 101. For example, the group identifier in the paging message may indicate a device group that does not include the first node 101. Alternatively, the device identifiers in the paging message may indicate devices that are all different from the first node 101. In this case, the first node 101 can determine that the second message has been sent.

[0290] In some embodiments, the first node 101 may determine that the second message has been sent successfully if it does not receive a first message indicating retransmission within a first time period after sending the last segment of the second message, i.e., the last first message. In some embodiments, if the first message indicating retransmission is not received after sending the last first message, the first node 101 may determine that the second node 102 has successfully received the last segment and determine that the second message has been sent successfully.

[0391] In the following, the technical solutions of the embodiments of this disclosure will be described by way of specific implementation.

[0392] This disclosure proposes segmentation processing. In some embodiments, it clarifies the information that needs to be cached in the temporary cache when the IoT device determines that segmentation is necessary, how to use this information for segmented new transmission or segmented retransmission, and how to update this information.

[0393] In some embodiments, the first device records the starting position of the first message and / or the length of the first message.

[0394] In some embodiments, for example, the first device is an IoT device, such as an A-IoT device or other IoT device. For example, the first message is a D2R message. For example, the first message is one segment of a second message. For example, the first message is the first segment of a second message. For example, the second message is a response message to a first command associated with the first device. For example, the first command can be a read command or other commands.

[0395] In some embodiments, the first device records the start and / or end position of the first message.

[0396] In some embodiments, the first device records the start and / or end position of the second message. The first device also records the start position and / or length of the second message. For example, the second message may be a portion of data in the memory of the first device, such as a stored file, address, or a portion of data in a device identifier.

[0397] In some embodiments, a first device receives a first command. For example, the first device receives a first command sent by a second device, which is a reader / writer, such as a base station (BS) reader / writer or an intermediate node. The first device determines a response to the first command (e.g., the device identifier indicated in the first command is the same as the first device identifier, which can be a temporary identifier (e.g., an access stratum (AS) ID) or a device identifier such as an EPC or a device identifier assigned by the core network / third party). The first device determines a second message based on the first command, for example, determining the start and / or end position of the second message. The first device determines that the second message needs to be segmented, for example, based on remaining battery power and / or a first resource, and for example, determining the length of the first message based on remaining battery power and / or the first resource. For example, the first message is the first segment of the second message. For example, the first resource can be the resource indicated in the first command. The first device records the start and / or end position of the second message and / or the start and / or length of the first message.

[0398] In some embodiments, the length of the first message is an integer multiple of bytes (8 bits). For example, the length of the first message is an integer multiple of two bytes (16 bits). For example, if the TBS of the first resource is not an integer multiple of bytes or two bytes, the first device can use padding to supplement it; that is, the length of the segment sent by the first device must be an integer multiple of bytes or two bytes. For example, the first device can store this integer multiple as the length of the first message.

[0399] In some embodiments, the length of the first message does not need to be an integer multiple of bytes (8 bits). For example, the first device may store the number of bits of the first message as the length of the first message.

[0400] In some embodiments, there are no restrictions on how the first device stores the start position of the first message and / or the length of the first message and / or the start position of the second message and / or the end position of the second message, nor on the amount of memory occupied by storing this information.

[0401] In some embodiments, the first device updates the start position and / or length of the first message according to the new / retransmission instruction of the second device.

[0402] In some embodiments, the second device indicates new transmission or retransmission and / or a second resource through first information, such as through 1 bit of indication information. The second resource is a new transmission resource or a retransmission resource. For example, new transmission refers to transmitting the next segment of the first message, and retransmission refers to retransmitting the first message. The indication information is set to a first value to indicate new transmission, and the indication information is set to a second value to indicate retransmission. For example, the first value is 1 and the second value is 0, or the first value is 0 and the second value is 1. The first device determines to retransmit the first message. The first device determines the retransmission of the first message based on the start position and / or end position of the stored / recorded second message and / or the start position and / or length of the first message. The first device determines the next segment of the new transmission of the first message. The first device determines the start position and / or length of the next segment based on the remaining battery power and / or the second resource and / or the start position and / or length of the first message. The first device sends the next segment as the first message and updates the start position and / or length of the first message.

[0403] In some embodiments, the first device determines that the second message has been sent and clears the stored start position of the first message and / or the length of the first message and / or the start position of the second message and / or the end position of the second message.

[0404] In some embodiments, the first device determines that the last segment / last first message of the second message was successfully transmitted, for example, by receiving a positive acknowledgment from the second device, or by not receiving a retransmission instruction from the second device after a preset time has elapsed since sending the last first message, or by receiving a paging message from the second device, or by receiving a second command from the second device, wherein the second command is a command different from the first command. After determining that the last first message was successfully transmitted, the first device clears the stored start position and / or length of the first message and / or start position and / or end position of the second message.

[0405] In some embodiments, when the first device determines that the second message has been sent, the first device clears the stored temporary identifier.

[0406] In some embodiments, the first device determines that the last segment / last first message of the second message was successfully transmitted, for example, by receiving a positive acknowledgment from the second device, or by not receiving a retransmission instruction from the second device after a preset time has elapsed since sending the last first message, or by receiving a second command sent by the second device, wherein the second command is a command different from the first command. Once the first device determines that the last first message was successfully transmitted, the first device clears the stored temporary identifier or considers the temporary identifier invalid.
