[0057] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0058] I. AIoT, also known as Ambient Power-enabled Internet of Things (Ambient Power-enabled IoT).

[0059] AIoT is a type of IoT business where IoT devices are powered through energy harvesting. These devices either do not have batteries or have limited energy storage capacity (e.g., using a capacitor). Energy sources for harvesting include radio waves, light, motion, heat, or other suitable energy sources.

[0060] Low-power IoT devices are a type of IoT device characterized by low overall power consumption, including low-power signal reception and low-power signal transmission. Due to their low overall power consumption, the energy for communication can be derived from the environment, such as wind power, kinetic energy, heat energy, or radio frequency (RF) signals. They can also be referred to as Ambient IoT or Passive IoT devices, or response devices.

[0061] Ambient IoT devices can be categorized based on their energy source, energy storage capability, and whether they are passive or active transmitters. This includes various device types.

[0062] Passive devices do not generate or amplify signals independently; they transmit signals via backscatter.

[0063] Semi-passive devices, which also belong to the category of passive devices, have energy storage but no independent signal generation, i.e., backscatter transmission. The use of stored energy can include amplification of reflected signals.

[0064] An active device is an active radio frequency component that has energy storage and independent signal generation for transmission.

[0065] II. Backscatter Communication (BSC).

[0066] Backscatter communication refers to the use of radio frequency signals from other devices or the environment to modulate signals and transmit information. As a passive or low-power technology, backscatter technology is characterized by its ability to transmit its own signals by altering the characteristics of the received environmental radio frequency signals, such as phase or amplitude information, thus achieving extremely low-power or zero-power information transmission.

[0067] One implementation of a backscatter transmission method based on on-off keying (OOK) is as follows: when the tag needs to send '1', the tag reflects the incident carrier signal; when the tag needs to send '0', it does not reflect the signal.

[0068] Backscatter communication devices control the reflection coefficient Γ of the circuit by adjusting its internal impedance, thereby changing the amplitude, frequency, and phase of the incident signal to achieve signal modulation. The signal reflection coefficient can be characterized as: Γ=(Z_1-Z_0) / (Z_1+Z_0)=|Γ|e^(jθ_T);

[0069] Where Z_0 is the characteristic impedance of the antenna, and Z_1 is the load impedance. Assuming the incident signal is S_in(t), the output signal is S_out(t) = S_in(t)|Γ|e^(jθ_T). Therefore, by reasonably controlling the reflection coefficient, the corresponding amplitude modulation, frequency modulation, or phase modulation can be achieved.

[0070] Backscatter communication devices typically employ low-power reception, generally using low-power radio frequency, intermediate frequency, or baseband envelope detection for signal reception. The transmitted signal waveform usually utilizes simple modulation methods, such as OOK, Amplitude Shift Keying (ASK), and Frequency Shift Keying (FSK).

[0071] The device that communicates with this type of low-power device is called a read / write device. It can be a terminal, a base station, or a device with read / write capabilities, such as a reader. The specific type is not limited here.

[0072] III. Information transmission between readers and tags in RFID.

[0073] RFID is a traditional backscatter communication system whose main design goal is to identify and read data from BSC devices (i.e., tags) within the reader's coverage area. Since RFID was initially used for automated inventory management of large quantities of goods, the process of identifying tags and reading data is also known as inventory management.

[0074] Taking the EPC C1G2 RFID system defined by ISO 18000-6c as an example, after the reader sends a query command, the tag responds. Taking RN16 as an example, the tag generates a 16-bit random number and sends it to the reader. Then, the reader sends this sequence to the tag via an ACK command. After the tag successfully verifies RN16 in the ACK, it sends subsequent data (such as Packet Core (PC), Evolved Packet Core (EPC), etc.) to the reader.

[0075] The instructions for Reader operations are shown in Table 1.

[0076] Table 1:

[0077] The status of the Tag is shown in Table 2.

[0078] Table 2:

[0079] IV. RFID Inventory Process.

[0080] The inventory process is shown in Figure 2, including:

[0081] 1. The reader first powers on and resets, and then sends a Select command to indicate the corresponding matching conditions to select this tag; the tag immediately switches to the Ready state.

[0082] 2. The reader sends a query command, and the tag determines whether to respond based on the inventory mark and SL mark.

[0083] The Query command initiates an inventory cycle and includes the Q value. The tag is located in (0, 2). Q -1) generates a random number as the initial value for the slot counter.

[0084] If the matching condition is met and the slot counter value is not 0, the system immediately enters the Arbitrate state.

[0085] Then, a Query_Rep command is sent to decrement the value of the time slot counter by 1.

[0086] The QueryAdjust command can change the Q value, causing the label to generate a new random number (0, 2). Q -1) is used as the value of the time slot counter.

[0087] If the matching condition is met and the slot counter is 0, respond to RN16 and immediately switch to the Reply state;

[0088] 3. The reader sends an ACK (RN16) command. The tag responds with the PC, ECP, and Cyclic Redundancy Check (CRC)-16 parameters and enters the Acknowledged state.

[0089] If the reader receives responses from multiple tags at the same time, it may not support processing responses from multiple tags at once, thus assuming a collision has occurred. The reader may not send an ACK. When a tag does not receive an ACK, its counter is randomly incremented by 0 or 1.

[0090] 4. In the Acknowledged state, after receiving the REQ_RN (RN16) instruction, the tag responds with RN16 and transitions to the Open or Secured state, allowing the reader to perform read and write operations on the tag.

[0091] As shown in Figure 3, in particular...

[0092] The colored box indicates a slot (e.g., Slot #3) with one and only one tag response;

[0093] The white box indicates an empty slot (e.g., Slot #1) that has no tag response;

[0094] The gray box indicates a conflicting slot (e.g., Slot #2) that has more than one tag response.

[0095] It should be noted that in this application, "slot" refers to a time unit with a non-fixed duration, also known as a time slot.

[0096] V. Q-algorithm of RFID protocol.

[0097] Step 0: The algorithm maintains a floating-point parameter Q, with an initial value of 4;

[0098] Step 1: At the beginning of the frame, the Reader broadcasts the Query command, and broadcasts 2... Q -1 frame length;

[0099] Step 2: After receiving the identification command, all Tag(s) respond starting from slot 0.

[0100] Step 3: After each slot, the Reader checks the result of that slot: if exactly one tag responds, there is no conflict, and the Q value remains unchanged; if it's an empty slot, subtract C from the Q value (C is a pre-defined constant ranging from 0.1 to 0.5, similar to a learning rate; after subtraction, Q must be less than 0); if it's a conflicting slot, add C to the Q value, and this Q value cannot exceed 15. After the slot ends, a rounding operation is performed to round the Q value to the nearest integer, and then the decision is made based on the Q value to either end the current frame or continue the current frame.

[0101] The environmental IoT AIoT operation processing method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0102] Referring to Figure 4, an embodiment of this application provides an environmental IoT AIoT operation processing method, as shown in Figure 4, which includes:

[0103] Step 401: The first device receives a first message from the second device. The first message includes time-domain configuration information, which is used to indicate the resource location where the second message is sent.

[0104] Step 402: The first device determines the location of the target resource based on the time-domain configuration information;

[0105] Step 403: The first device sends a second message to the second device at the target resource location, the second message including the random access identifier of the AIoT device;

[0106] Step 404: The first device receives a third message from the second device, the third message including response information corresponding to the random access identifier of at least one AIoT device;

[0107] The first device is an AIoT device.

[0108] In this embodiment, the aforementioned first message can be understood as an initial broadcast message, also known as Msg0, used to trigger the execution of AIoT operations. AIoT operations can also be understood or replaced with one of the following: AIoT task, AIoT process, AIoT command, or AIoT service. For example, it may include at least one of the following: inventorying one or more AIoT devices, reading from one or more AIoT devices, writing to one or more AIoT devices, enabling one or more AIoT devices, or disabling one or more AIoT devices.

[0109] Optionally, the AIoT device may include at least one of a BSC device and a tag device.

[0110] Optionally, the above time-domain configuration information can be understood as or replaced with time slot(s) configuration information. The above resource location can be understood as or replaced with time-domain resource location.

[0111] Optionally, in some embodiments, the aforementioned time-domain configuration information is used to indicate one or more resource locations. The first device can select a target resource location from one or more resource locations and send a second message from the target resource location. It should be noted that the method by which the first device selects the target resource location can be set according to actual needs. For example, in some embodiments, the first device can randomly select one resource location from the indicated multiple resource locations as the target resource location, or it can select the corresponding resource location as the target resource location based on the mapping relationship between resource locations and AIoT devices.

[0112] Optionally, the random identifier can be a 16-bit random number, abbreviated as RN16.

[0113] It should be understood that if a four-step access procedure is supported (e.g., Msg1, Msg2, Msg3, Msg4 of 4-step RACH), it can correspond to the second, third, fourth, and fifth messages of this application.

[0114] It can also be understood that if a two-step access process is supported (e.g., MsgA, MsgB of 2-step RACH), it can correspond only to the second and third messages of this application.

[0115] Optionally, the content of the second and third messages may differ in the four-step access process and the two-step access process. For example, the content of the second and fourth messages in the four-step access process may be merged into one message (i.e., equivalent to the content of the second message in the two-step access process), and the content of the third and fifth messages in the four-step access process may be merged into one message (i.e., equivalent to the content of the third message in the two-step access process).

[0116] Optionally, in some embodiments, the above-mentioned response information can be used to indicate the access result, such as access success or access failure. In some embodiments, this can be indicated by positive acknowledgment (ACK) and negative acknowledgment (NACK).

[0117] It should be understood that in the embodiments of this application, receiving refers to performing the receiving action, and does not represent the result of receiving. For example, receiving a third message means performing the receiving action of receiving a third message, which may result in two outcomes: not receiving the third message and receiving the third message.

[0118] This application embodiment involves a first device receiving a first message from a second device. The first message includes time-domain configuration information, which indicates the resource location from which the second message is sent. The first device determines a target resource location based on the time-domain configuration information. The first device then sends a second message to the second device at the target resource location. The second message includes a random access identifier for the AIoT device. The first device receives a third message from the second device. The third message includes response information corresponding to at least one random access identifier of an AIoT device. Here, the first device is an AIoT device. Thus, this application embodiment clarifies the access interaction process for AIoT devices, thereby realizing the access process of AIoT devices in AIoT operations.

[0119] Optionally, in some embodiments, the time-domain configuration information includes any of the following:

[0120] At least one time slot allocation, wherein a resource location is one time slot or multiple consecutive time slots in the at least one time slot allocation;

[0121] At least one random access occasion, and a resource location is one of the at least one random access occasions or a series of random access occasions.

[0122] In this embodiment, a resource location is represented by one slot as an example. It is assumed that the time-domain configuration information includes L slots, where L is an integer greater than 1. The method for determining the target resource location may include any of the following:

[0123] Method 1: Generate a random number between [0, L-1] based on the total number of slots L, and use the value of the random number as your access slot (i.e., target resource location). For example, if the random number is 2, then the second slot among the configured slots (counting from the 0th slot) will be used as the access slot.

[0124] Method 2: The slot configured in the time domain configuration information can have a mapping relationship with a type of AIoT device information (such as device identifier or session identifier). The specific time domain configuration information can configure this mapping relationship, and the AIoT device can determine its access slot based on the AIoT device information and the mapping relationship.

[0125] In this embodiment of the application, when at least two resource locations are indicated by time-domain configuration information, the AIoT device can select different resource locations from the indicated resource locations to send a third message, thereby realizing AIoT operation in a time-division multiplexing manner, thus reducing the latency of AIoT operation.

[0126] Optionally, in some embodiments, the first message further includes at least one of the following:

[0127] The transport block size (TBS) or grant size (GS) carrying the second message, or the upper limit of the transport block size or grant size carrying the second message;

[0128] First indication information, the first indication information is used to indicate whether the second message is allowed to carry the first transmission container, or whether the second message carries the first transmission container;

[0129] The first transmission container is a transmission container from the AIoT device to the second device.

[0130] In this application embodiment, the first transmission container described above can be understood or replaced as a device-to-reader (D2R) container.

[0131] Optionally, in some embodiments, the first transmission container is used to transmit at least one of the following: high-level identification information of the AIoT device; high-level messages of the AIoT device; service data of the AIoT device; session identifier of the AIoT device; and identification information of the second device.

[0132] Optionally, the aforementioned business data may include at least one of at least a portion of the EPC code and at least a portion of the authentication code corresponding to the EPC code. The aforementioned high-level messages may include registration accept messages and control plane service accept messages, etc.

[0133] Optionally, in some embodiments, the second message further includes at least one of the following:

[0134] First transmission container;

[0136] The identification information of the second device.

[0137] In this embodiment, the content of the second message can be selected by the first device itself, or it can be determined by the configuration of the second device. Optionally, whether the second message carries the first transmission container can be determined based on the content carried in the first message, for example, based on at least one of the first indication information and the transmission block size carrying the second message or its upper limit value.

[0138] Optionally, in some embodiments, the above-mentioned capability information includes at least one of the following:

[0141] The maximum number of segments supported by the first transmission;

[0142] Does it support the segmentation function of the second transmission, which is the transmission from the second device to the AIoT device?

[0143] The second transmission supports a maximum number of segments.

[0144] Optionally, in some embodiments, the identification information of the second device includes at least one of the following: reader identity, Public Land Mobile Network (PLMN) identifier, cell identity, Tracking Area Code, RAN-based Notification Area Code, carrier ID, and Physical Cell Identifier (PCI).

[0146] The target identifier is a temporary identifier assigned by the second device to the AIoT device;

[0147] First physical layer parameter information, which is used by the AIoT device to send a fourth message to the second device;

[0148] The second transmission container is a transmission container from the second device to the AIoT device.

[0149] In this embodiment of the application, the aforementioned second transmission container can be understood or replaced as a Reader-to-Device (R2D) container. Specifically, the second transmission container can be a transmission container received by the second device from the core network.

[0150] Optionally, the target identifier mentioned above can be an Access Network Temporary Identifier (RAN Temp ID). From the perspective of the second device, different AIOT devices are distinguished based on at least one of the random identifiers generated by different AIOT devices and the Msg1 resource locations sent by different AIOT devices, and a RAN Temp ID is assigned to replace the random identifier. This temporary identifier is used to establish an association between the communication objects at the transport layer and the operation objects of higher-layer instructions (e.g., Read, Write, Kill) processes. From the perspective of the AIOT device, the RAN Temp ID is used to correspond to the AIOT device's reception process on the physical layer channel (e.g., PRDCH).

[0151] Optionally, in some embodiments, the first physical layer parameter information mentioned above includes at least one of resource location, modulation parameters, and coding parameters.

[0152] Optionally, in some embodiments, when the first device receives the third message, the method further includes at least one of the following:

[0153] If the response information includes positive information, and the random access identifier associated with the positive information includes the random access identifier contained in the second message, the first device determines that the access is successful.

[0154] If the response information includes positive information, and the random access identifier associated with the positive information does not include the random access identifier contained in the second message, the first device determines that the access has failed.

[0155] If the response information includes negative information, and the random access identifier associated with the negative information includes the random access identifier contained in the second message, the first device determines that the access has failed.

[0156] If the response information only includes negative information, and the random access identifier associated with the negative information does not include the random access identifier contained in the second message, the first device determines that the access is successful.

[0157] In this embodiment of the application, the above response information can be understood as the ACK information field or the NAK information field.

[0158] The first device considers its access process successful if one of the following conditions is met:

[0159] Condition 1: The third message contains an ACK information field and a NAK information field, and the random identifier in the second message sent by the first device itself is included in the relevant field of the ACK information (explicitly indicated);

[0160] Condition 2: The third message contains only the ACK information field, and the random identifier in the second message 1 sent by the first device itself is included in the relevant field of the ACK information (explicitly indicated);

[0161] Condition 3: The third message contains only the NAK information field, and the random identifier in the second message sent by the first device itself is not included in the relevant field of the NAK information (default indication).

[0162] Optionally, assuming the access process is successful, if the third message contains other content, then the content is further activated or applied according to the content indication field. If the content indication field indicates that it belongs to physical layer parameter information, it is submitted to the physical layer for further activation or application; if it belongs to MAC layer content, it is activated or applied directly; if it belongs to upper layer (above AS layer, such as AIoT layer or NAS layer) content, it is submitted to the upper layer for further activation or application.

[0163] The first device considers its access process to have failed if one of the following conditions is met:

[0164] Condition 4: The third message contains an ACK information field and a NAK information field, and the random identifier in the second message sent by the first device itself is included in the relevant field of the NAK information (explicitly indicated);

[0165] Condition 5: The third message contains only the NAK information field, and the random identifier in the second message sent by the first device itself is included in the relevant field of the NAK information (explicitly indicated);

[0166] Condition 6: The third message contains only the ACK information field, and the random identifier in the second message sent by the first device itself is not included in the relevant field of the ACK information (default indication).

[0167] Optionally, if the access process fails and the third message contains other content, it can be ignored or discarded.

[0168] Optionally, in some embodiments, after the first device determines that the access is successful, the method further includes:

[0169] The first device sends a fourth message to the second device, the fourth message including at least one of the following:

[0170] First transmission container;

[0171] Capability information of AIoT devices.

[0172] It should be noted that, in the various embodiments of this application, the AIOT device-related information included in the messages sent by the AIOT device to the second device refers to its own related information. For example, the AIOT device capability information included in the fourth message can be understood as the first device's capability information, and the AIOT device's random access identifier included in the second message can be understood as the first device's random access identifier.

[0173] Optionally, in some embodiments, after the first device sends a fourth message to the second device, the method further includes:

[0174] The first device receives a fifth message from the second device, the fifth message including at least one of the following:

[0175] Second transmission container;

[0176] The target identifier is a temporary identifier assigned by the second device to the AIoT device;

[0177] The second physical layer parameter information is used by the AIoT device to send a sixth message to the second device.

[0178] In this embodiment of the application, the aforementioned second physical layer parameter information includes at least one of resource location, modulation parameters, and coding parameters.

[0179] Optionally, in some embodiments, the resource location of the fourth message is determined based on any of the following:

[0180] The third message carries the first physical layer parameter information;

[0181] The location of the target resource;

[0182] The resource location of the third message;

[0183] The preamble associated with the fourth message.

[0184] Optionally, if the resource location of the fourth message is determined based on the first physical layer parameter information, the resource location in the first physical layer parameter information can be determined as the resource location of the fourth message.

[0185] Optionally, if the resource location of the fourth message is determined based on the target resource location, the resource location of the fourth message can be determined jointly based on the target resource location and a time offset. This time offset can be set according to actual needs.

[0186] Optionally, if the resource location of the fourth message is determined based on the resource location of the third message, the resource location of the fourth message can be determined jointly based on the resource location of the third message and a time offset. This time offset can be set according to actual needs.

[0187] Optionally, if the resource location of the fourth message is determined based on the preamble associated with the fourth message, the location of the fourth message can be determined based on the resource location indicated by the preamble associated with the fourth message. For example, the preamble associated with the fourth message can be understood as a preamble sent before the sending location of the fourth message. Optionally, the aforementioned fourth message can be understood or replaced as Msg3, and a D2R preamble is sent before the sending location of Msg3, and the preamble associated with the fourth message can be understood as this D2R preamble.

[0188] Optionally, in some embodiments, the method further includes:

[0189] The first device receives a seventh message from the second device;

[0190] The first device performs the target action based on the seventh message;

[0191] Wherein, the seventh message is a duplicate of the first message, and the time-domain configuration information contained in the seventh message is different from the time-domain configuration information contained in the first message, and the target behavior includes any of the following:

[0192] The second message is resent based on the seventh message;

[0193] Ignore the seventh message.

[0194] In this embodiment of the application, when an AIoT device sends the content of the second message at its selected target resource location, at least two AIoT devices may have selected the same target resource location, resulting in an access conflict. When the second device determines that there are at least two AIoT devices with access conflicts, it can re-enter the access process by sending a seventh message.

[0195] Optionally, an AIoT device that is deemed to have failed to connect can resend the second message based on the seventh message, and after the second message has been resent, it will continue to receive the third message.

[0196] Optionally, AIoT devices that are considered to have successfully connected can directly ignore the seventh message.

[0197] It should be noted that, in some embodiments, to ensure that the repeatedly sent seventh message only applies to all AIoT devices experiencing access conflicts, the seventh message can be sent after the third message has been sent to AIoT devices that have not experienced access conflicts. That is, in some embodiments, the resource location of the seventh message is located after the resource location of the target message, and the target message is the third message corresponding to the AIoT device that has not experienced an access conflict.

[0198] In some embodiments, the resource location of the seventh message is free from conflict and can be located before or after the third message of any AIoT device. The AIoT device can determine whether it has experienced an access conflict by combining the content of the seventh message. For example, in some embodiments, the seventh message may include at least one of the following:

[0199] The second indication information is used to indicate the AIoT device that has experienced an access conflict;

[0200] The third indication information is used to indicate AIoT devices that have not experienced access conflicts.

[0201] Optionally, in some embodiments, the second and third indication information may include the random access identifier of the AIoT device. Of course, in other embodiments, other identification information may be used to indicate the AIoT device, which is not further limited here.

[0202] Optionally, in the embodiments of this application, the target behavior satisfies at least one of the following:

[0203] If the target conditions are met, the second message will be resent based on the seventh message;

[0204] If the target conditions are not met, the seventh message is ignored;

[0205] The target conditions include at least one of the following:

[0206] The seventh message includes second indication information, and the second indication information indicates that the first device is among the AIoT devices that have experienced access conflicts.

[0207] The seventh message includes a third indication, which indicates that the first device is not among the AIoT devices that have not experienced an access conflict.

[0208] In this embodiment of the application, the second indication information indicates that the AIoT device in which the access conflict occurs includes the first device, which can be understood or replaced by the random access identifier of the second indication information including the random access identifier of the first device.

[0209] Optionally, in some embodiments, the time-domain configuration information included in the seventh message is used to indicate any of the following:

[0210] At least one time slot allocation, and a resource location is one time slot or multiple consecutive time slots in the at least one time slot allocation;

[0211] At least one random access opportunity, and a resource location is one of the at least one random access opportunity or a series of random access opportunities;

[0212] The number of resource locations indicated by the time-domain configuration information is related to the access conflict of AIoT devices.

[0213] In this embodiment, the second device can further adjust the time-domain configuration information in the seventh message based on at least one of the results of AIoT devices experiencing access conflicts and those that do not. For example, after considering factors such as the number of conflicting AIoT devices, the number of conflicting resource locations, the proportion of conflicting AIoT devices, and the proportion of conflicting resource locations, if the number of conflicting AIoT devices is too large or the proportion of conflicting resource locations is too high, the resource location quantity configuration can be increased. This can reduce the probability of subsequent AIoT device access conflicts.

[0214] To better understand this application, the following examples will be used to illustrate it in detail.

[0215] Referring to Figure 5a, and taking the resource location indicated by the time-domain configuration information as a slot, and the AIoT operation as an inventory operation as an example, the following process is included:

[0216] Step 501: The Reader sends an initial broadcast message Msg0 to trigger an inventory of at least one AIoT device. Msg0 can be understood as an inventory request.

[0217] The Msg0 includes at least one of the following pieces of information:

[0218] The time-domain configuration information for the next D2R transmission (i.e., Msg1);

[0219] The transport block resource grant size carrying Msg1, or the upper limit of the resource grant transport block size carrying Msg1;

[0220] Whether to allow, support, or instruct Msg1 to carry the first transmission container;

[0221] Reader identification information.

[0222] Step 502: The AIoT device receives Msg0 and, on the premise of responding to the inventory request of the first device, determines the location of the resource sent by Msg1 and the content it carries.

[0223] Optionally, regarding the resource location sent by Msg1, one of the slots can be selected as the slot for Msg1 to be sent, based on the time-domain configuration information included in Msg0.

[0224] The content carried by Msg1 includes at least one of the following:

[0225] A random access identifier;

[0226] A first transmission container;

[0227] Reader identification information.

[0228] Step 503, the AIOT device sends Msg1, for example, the AIOT device sends its own Msg1 content on a slot it selects or based on its configuration.

[0229] For example, an AIoT device sends Msg1 on slot_M1, and another AIoT device sends Msg1 on slot_N1 (no time domain conflict occurs).

[0230] Step 504: The Reader receives Msg1 from at least one AIOT device and determines the resource location and content sent by Msg2. Here, Msg2 is a response message to one of the at least one AIOT devices' Msg1.

[0231] Alternatively, the location of the resource sent by Msg2 can be determined based on any of the following methods.

[0232] Method 1: The Msg2 transmission position is related to the position of the R2D preamble accompanying the Msg2 transmission. For example, the R2D preamble is transmitted before the Msg2 transmission position, and the detected R2D preamble indicates the Msg2 transmission position. See Figure 5b.

[0233] Method 2: The transmission position of Msg2 is related to the transmission position of Msg0, for example, it is determined by combining the slot position transmitted by Msg0 and a time offset. For instance, the transmission position of Msg2 is equal to the slot position transmitted by Msg0 plus a first time offset, as shown in Figure 5c.

[0234] Method 3: The transmission position of Msg2 is related to the transmission position of Msg1, for example, it is determined by combining the slot position transmitted by Msg1 and a time offset. For instance, the transmission position of Msg2 is equal to the slot position transmitted by Msg1 plus a second time offset, as shown in Figure 5d.

[0235] The content carried by Msg2 includes at least one of the following:

[0236] The random identifier in Msg1 corresponds to the ACK or NAK information;

[0237] A RAN Temp ID;

[0238] The physical layer parameter information for the next D2R transmission (i.e., Msg3).

[0239] Specifically, the ACK or NAK information here needs to be combined with the random identifier in Msg1 to determine which AIoT device corresponds to the ACK or NAK. For example, an explicit indication method is used: if the random identifier in the Msg1 of an AIoT device is included in the relevant field of the ACK information, it indicates an ACK for that AIoT device; or, if the random identifier in the Msg1 of an AIoT device is included in the relevant field of the NAK information, it indicates a NAK for that AIoT device. Another example is an implicit indication method using a default: if the random identifier in the Msg1 of an AIoT device is not included in the relevant field of the ACK information, it indicates a NAK for that AIoT device; or, if the random identifier in the Msg1 of an AIoT device is not included in the relevant field of the NAK information, it indicates an ACK for that AIoT device.

[0240] Step 505, Reade sends Msg2. For example, Reade sends Msg2 messages to each of the at least one AIoT device according to the resource location and content of the determined Msg2 message.

[0241] Step 506: The AIoT device determines whether the access was successful or failed. For example, the AIoT device receives Msg2 and determines whether the access process was successful or failed based on the content carried by Msg2.

[0242] Your access process is considered successful if one of the following conditions is met.

[0243] Condition 1: Msg2 contains an ACK information field and a NAK information field, and the random identifier in its own Msg1 is included in the relevant field of the ACK information (explicitly indicated);

[0244] Condition 2: Msg2 contains only the ACK information field, and the random identifier in its own Msg1 is included in the relevant field of the ACK information (explicitly indicated);

[0245] Condition 3: Msg2 contains only the NAK information field, and the random identifier in its own Msg1 is not included in the relevant field of the NAK information (default indication).

[0246] Optionally, assuming the access process is successful, if Msg2 contains other content, then further activation or application of other content will be determined according to the content indication field. If the content indication field indicates that it belongs to physical layer parameter information, it will be submitted to the physical layer for further activation / application; if it belongs to MAC layer content, it will be activated or applied directly; if it belongs to upper layer (above AS layer, such as AIoT layer or NAS layer) content, it will be submitted to the upper layer for further activation or application.

[0247] Your access process is considered to have failed if any of the following conditions are met.

[0248] Condition 4: Msg2 contains an ACK information field and a NAK information field, and the random identifier in its own Msg1 is included in the relevant field of the NAK information (explicitly indicated);

[0249] Condition 5: Msg2 contains only the NAK information field, and the random identifier in its own Msg1 is included in the relevant field of the NAK information (explicitly indicated);

[0250] Condition 6: Msg2 contains only the ACK information field, and the random identifier in its own Msg1 is not included in the relevant field of the ACK information (default indication).

[0251] Optionally, if Msg2 contains other content and the access process fails, it can be ignored or discarded.

[0252] Step 507: The AIoT device sends Msg3. For successfully connected AIoT devices, the AIoT device sends Msg3 to the Reader.

[0253] The content carried by Msg3 includes at least one of the following:

[0254] First transmission container;

[0255] Capability information of AIoT devices.

[0256] The location of the resource sent by Msg3 can be determined using any of the following methods.

[0257] In Method 1, the Msg3 transmission location is determined based on the physical layer parameter information of the next D2R transmission (i.e., Msg3) indicated by the content carried by Msg2.

[0258] Method 2: The transmission position of Msg3 is related to the transmission position of Msg1. For example, it is determined jointly based on the slot position transmitted by Msg1 and a time offset. For instance, the transmission position of Msg3 is equal to the slot position transmitted by Msg1 plus a third time offset, as shown in Figure 5e.

[0259] Method 3: The transmission position of Msg3 is related to the transmission position of Msg2. For example, it is determined jointly based on the slot position transmitted by Msg2 and a time offset. For instance, the transmission position of Msg3 is equal to the slot position transmitted by Msg2 plus a fourth time offset, as shown in Figure 5f.

[0260] Method 4: The Msg3 transmission position is related to the position of the D2R preamble accompanying the Msg3 transmission. For example, the D2R preamble is transmitted before the Msg3 transmission position, and the detected preamble indicates the Msg3 transmission position. See Figure 5g.

[0261] Step 508: The Reader sends the first transmission container to the core network device. For example, upon receiving Msg3 from the AIoT device, the Reader forwards the first transmission container in Msg3 to the core network device.

[0262] Step 509: The Reader sends Msg4. For example, if the Reader receives a second transport container from the core network device for a certain AIoT device, the Reader puts it into Msg4 and sends it to the corresponding AIoT device.

[0263] Msg4 carries at least one of the following:

[0264] A second transport container;

[0265] A RAN Temp ID;

[0266] The physical layer parameter information for the next D2R transmission (i.e., Msg5).

[0267] Optionally, the AIoT device checks whether the ACK information or RAN temp ID in the aforementioned Msg2 has been sent to it as Msg4. If so, it further parses and processes Msg4. Specifically, this includes distinguishing whether to further activate or apply other content based on the content indication field.

[0268] It should be noted that Msg2 in the above embodiments is a one-to-one response; in some embodiments, it can also be a one-to-many response. In this case, the resource position sent by Msg2 can be determined based on the content of Msg0. For example, it can be determined jointly based on the preset slot position and the fifth time offset in the time-domain configuration information included in Msg0. The preset slot position can be agreed to be the starting slot position (slot#0), the middle slot position (slot#3 or slot#4), or the last slot position (slot#7) in the time-domain configuration information as a reference slot; for example, the sending position of Msg2 is equal to the preset slot position plus the fifth time offset, as shown in Figure 5h.

[0269] The content carried by Msg2 includes at least one of the following:

[0270] At least one ACK or NAK message corresponding to the random identifier in Msg1;

[0271] At least one RAN Temp ID;

[0272] At least one physical layer parameter information for the next D2R transmission (i.e., Msg3).

[0273] It should be noted that in some embodiments, if a two-step access process is adopted, the flowchart of the two-step access process corresponding to Figure 5a is shown in Figure 5i.

[0274] Optionally, in some embodiments, conflicts may occur during the AIoT device access process. As shown in Figure 6, the process includes the following steps:

[0275] Steps 601 to 603 are the same as steps 501 to 503, except that at least two AIoT devices send Msg1 on the same slot (e.g., slot_N1), which leads to an access conflict.

[0276] In step 604, if the Reader determines that at least two AIoT devices have access conflicts, it will resend Msg0. The resent Msg0 will be at least partially different from the previously sent Msg0, for example, the time domain configuration information will be different.

[0277] Optionally, if the AIoT device receives a Msg0 that is repeatedly sent by the Reader before receiving Msg2, the AIoT device shall perform at least one of the following actions: stop the ongoing access process; consider the access process to have failed; or, based on the repeatedly sent Msg0, jump to the step of determining the resource location and content carried by Msg0 and re-access the device.

[0278] Optionally, the AIoT device performs at least one of the following actions based on the content of the repeatedly sent Msg0: stops the ongoing access process; considers the access process to have failed; or, based on the repeatedly sent Msg0, jumps to the step of determining the resource location and content carried by the Msg0, and re-attempts access. For example, the repeatedly sent Msg0 may carry the aforementioned second and third indication information, and the AIoT device may determine whether the access process has failed based on at least one of the second and third indication information.

[0279] Referring to Figure 7, this application embodiment also provides an AIOT operation processing method, as shown in Figure 7, the AIOT operation processing method includes:

[0280] Step 701: The second device sends a first message to the AIOT device. The first message includes time-domain configuration information, which is used to indicate the resource location where the second message is sent.

[0281] Step 702: The second device receives a second message from the AIOT device at the target resource location. The second message includes a random access identifier of the AIOT device, and the target resource location is determined based on the time-domain configuration information.
