[0057] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0058] 1. AIoT, also known as the Ambient power-enabled Internet of Things (Ambient power-enabled IoT).

[0059] AIoT is an IoT service where IoT devices are powered by energy harvesting. IoT devices do not have batteries or have limited energy storage capabilities (for example, using a capacitor). Energy sources for energy harvesting include radio waves, light, motion, heat, or other suitable energy sources.

[0060] Low-power IoT devices are IoT devices with low overall power consumption, including low-power signal reception and low-power signal transmission. Due to their low overall power consumption, communication energy can come from environmental sources such as wind, kinetic energy, thermal energy, and RF signals. They are also called ambient IoT, passive IoT, and transponder devices.

[0061] Ambient IoT devices can be classified based on energy source, energy storage capability, passive or active emission, etc. There are many types of devices:

[0062] Passive devices (Passive Devices) have no independent signal generation or amplification, that is, backscatter transmission;

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

[0064] Active devices have energy storage and independent signal generation, that is, active RF components used for transmission.

[0065] 2. Backscatter Communication (BSC)

[0066] Backscatter communication involves a device using radio frequency signals from other devices or the environment to modulate its signal and transmit its own information. Backscatter, a passive or low-energy technology, is characterized by its ability to transmit its own signal by modifying the characteristics of the received ambient radio frequency signal, such as its phase or amplitude, achieving extremely low or zero power consumption.

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

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

[0069] Where Z_0 is the antenna characteristic impedance, 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 properly controlling the reflection coefficient, corresponding amplitude modulation, frequency modulation, or phase modulation can be achieved.

[0070] Backscatter communication equipment typically uses low-power reception, typically using low-power RF, IF, or baseband envelope detection. The transmitted signal waveform typically uses simple modulation schemes 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, which can be, for example, a terminal, a base station, or a device with read-write functions, such as a reader / writer, and the specific details are not limited here.

[0072] 3. Information transmission between reader and tag devices in RFID.

[0073] RFID is a traditional backscatter communication system designed to identify and read data from BSC devices (i.e., tags) within the reader's coverage area. Because RFID was initially used for automated inventory counting of large quantities of goods, the process of tag identification and data reading is also known as inventory taking.

[0074] Take the EPC C1G2 RFID system defined in ISO 18000-6c as an example. After the reader sends a query command (Query), the tag responds (Reply). For example, if the Reply is RN16, the tag generates a 16-bit random number and sends it to the reader. The reader then sends this sequence to the tag using the ACK command. After successfully verifying the RN16 in the ACK, the tag sends subsequent data (such as Packet Core (PC) and Evolved Packet Core (EPC)) to the reader.

[0075] Reader operation instructions are shown in Table 1.

[0076] Table 1:

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

[0078] Table 2:

[0079] 4. RFID inventory process.

[0080] The inventory process is shown in Figure 2 and includes:

[0081] 1. The reader is first powered on and reset, and 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 starts an inventory cycle. The Query command contains the Q value. The tag is in (0, 2 Q -1) generates a random number as the initial value of the slot counter.

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

[0085] Then send the Query_Rep command to reduce the value of the time slot counter by 1;

[0086] The QueryAdjust command can change the Q value and let the tag regenerate a new random number (0, 2 Q -1) as the value of the time slot counter.

[0087] If the matching condition is met and the time 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 be able to process multiple tags at once, and a collision occurs. The reader may not send an ACK. If the tag does not receive an ACK, the counters of these tags will be randomly incremented by 0 or 1.

[0090] 4. In the Acknowledged state, after receiving the REQ_RN (RN16) command, the tag responds with RN16 and switches to the Open or Secured state. The reader can read and write to this tag.

[0091] As shown in Figure 3,

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

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

[0094] Gray boxes indicate conflicting slots (e.g., Slot#2) that are responded to by more than one tag.

[0095] It should be noted that in this application, slot refers to a time unit of non-fixed duration, which can also be called a time slot.

[0096] 5. 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: Reader broadcasts Query command at the beginning of the frame and broadcasts 2 Q -1 frame length;

[0099] Step 2: After receiving the identification command, the 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 is an empty slot, C is subtracted from the Q value (C is a pre-set constant ranging from 0.1 to 0.5, similar to a learning rate; after subtraction, Q is less than 0). If it is a conflicting slot, C is added to the Q value, and the Q value cannot exceed 15. After the slot ends, the Q value is rounded up, and the Q value is used to decide whether to end the current frame or continue.

[0101] The following, in conjunction with the accompanying drawings, describes in detail the environmental Internet of Things (AIOT) operation processing method provided by the embodiment of the present application through some embodiments and their application scenarios.

[0102] 4 , an embodiment of the present application provides an environmental Internet of Things (AIOT) operation processing method. As shown in FIG4 , the environmental Internet of Things (AIOT) operation processing method includes:

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

[0104] Step 402: The first device determines a target resource location according to the time domain configuration information;

[0105] Step 403: The first device sends a second message to the second device at the target resource location, where the second message includes a random access identifier of the AIOT device.

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

[0107] Among them, the first device is an AIOT device.

[0108] In the embodiment of the present application, the above-mentioned first message can be understood as an initial broadcast message, which can also be referred to as Msg0, which is used to trigger the execution of AIOT operations. AIoT operations can also be understood or replaced by one of the following: AIoT tasks, AIoT processes, AIoT commands, AIoT services. For example, it includes at least one of the following: inventorying one or more AIoT devices, reading one or more AIoT devices, writing one or more AIoT devices, enabling one or more AIoT devices, disabling one or more AIoT devices, etc.

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

[0110] Optionally, the time domain configuration information may be understood or replaced by time slot(s) configuration information. The resource location may be understood or replaced by time domain resource location.

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

[0112] Optionally, the random access identifier (random identifier) ​​may be a 16-bit random number, referred to as RN16.

[0113] It should be understood that if a four-step access process is supported (for example, Msg1, Msg2, Msg3, Msg4 of 4-step RACH), it can correspond to the second message, third message, fourth message, and fifth message of the present application.

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

[0115] Optionally, the content of the second message and the third message sent in the four-step access process and the two-step access process is different. For example, the content of the second message and the content of the fourth message in the four-step access process can be combined into one message and sent (i.e., equivalent to the content of the second message in the two-step access process), and the content of the third message and the content of the fifth message in the four-step access process can be combined into one message and sent (i.e., equivalent to the content of the third message in the two-step access process).

[0116] Optionally, in some embodiments, the response information may be used to indicate an access result, such as access success or access failure. In some embodiments, the response information may be indicated by a positive acknowledgement (ACK) or a negative acknowledgement (NACK).

[0117] It should be understood that in the embodiments of the present application, receiving refers to the execution of the receiving behavior, and does not indicate the result of receiving. For example, receiving the third message refers to the execution of the receiving behavior of receiving the third message, and there may be two results: not receiving the third message or receiving the third message.

[0118] In an embodiment of the present application, a first device receives a first message from a second device, the first message including time domain configuration information, the time domain configuration information being used to indicate the resource location to which the second message is to be sent; the first device determines the target resource location based on the time domain configuration information; the first device sends a second message to the second device at the target resource location, the second message including a random access identifier of an AIOT device; 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; wherein the first device is an AIOT device. In this way, the embodiment of the present application clarifies the access interaction process of 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 one of the following:

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

[0121] At least one random access occasion, wherein one resource location is one random access occasion or a plurality of consecutive random access occasions in the at least one random access occasion.

[0122] In the embodiment of the present application, a resource location is taken as a slot for example, and it is assumed that the time domain configuration information includes L slots, where L is an integer greater than 1. The above-mentioned 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 its own access slot (i.e., the target resource location). For example, if the random number is 2, the second slot (counting from the 0th slot) among the configured multiple slots is used as the access slot.

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

[0125] In an embodiment of the present application, when at least two resource locations are indicated by time domain configuration information, the AIOT device can select a different resource location from the indicated resource locations to send a third message, thereby realizing time division multiplexing to perform AIOT operations, thereby reducing the latency of AIOT operations.

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

[0149] In the embodiment of the present application, the second transmission container can be understood or replaced by a reader-to-device (R2D) container, wherein the second transmission container can be a transmission container received by the second device from the core network.

[0150] Optionally, the above-mentioned target identifier can be an access network temporary identifier (RAN Temp ID). From the perspective of the second device, different AIOT devices are distinguished according to the random identifier generated by different AIOT devices and at least one of the Msg1 resource locations sent by different AIOT devices, and a RAN Temp ID temporary identifier is assigned to replace the random identifier, which is used to establish an association between the communication object at the transmission layer and the operation object of the high-level instruction (such as Read, write, kill) process; from the perspective of the AIOT device, the RAN Temp ID is used to correspond to the AIOT device in the physical layer channel (for example, PRDCH) receiving process.

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

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

[0153] In a case where the response information includes affirmative information, and the random access identifier associated with the affirmative information includes the random access identifier included in the second message, the first device determines that the access is successful;

[0154] In a case where the response information includes affirmative information, and the random access identifier associated with the affirmative information does not include the random access identifier included in the second message, the first device determines that the access fails;

[0155] In a case where the response information includes negative information, and the random access identifier associated with the negative information includes the random access identifier included in the second message, the first device determines that the access fails;

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

[0157] In the embodiment of the present application, the above-mentioned response information can be understood as an ACK information field or a NAK information field.

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

[0161] Condition 3: The third message only includes 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, if the access process is successful, if the third message also contains other content, the other content is further validated 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 validation or application; if it is content belonging to the MAC layer, it is directly validated or applied; if it is content belonging to an upper layer (above the AS layer, such as the AIOT layer or NAS layer), it is submitted to the upper layer for further validation or application.

[0163] If any of the following conditions is met, the first device considers its access process failed:

[0164] Condition 4: The third message includes 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 (explicit indication);

[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 (explicit indication);

[0166] Condition 6: The third message only includes an 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, under the premise that the access process fails, if the third message also contains other content, it is directly 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, where the fourth message includes at least one of the following:

[0170] a first transport container;

[0171] Capability information of AIOT devices.

[0172] It should be noted that in each embodiment of the present application, the information about the AIOT device included in the message sent by the AIOT device to the second device refers to the information about the AIOT device itself. For example, the capability information of the AIOT device included in the fourth message can be understood as the capability information of the first device, and the random access identifier of the AIOT device included in the second message can be understood as the random access identifier of the first device.

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

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

[0175] a second transport container;

[0176] A target identifier, where the target identifier is a temporary identifier allocated by the second device to the AIOT device;

[0177] Second physical layer parameter information, where the second physical layer parameter information is used by the AIOT device to send a sixth message to the second device.

[0178] In an embodiment of the present application, the above-mentioned second physical layer parameter information includes at least one of a resource location, a modulation parameter and a coding parameter.

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

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

[0181] the target resource location;

[0182] The resource location of the third message;

[0183] The preamble code associated with the fourth message.

[0184] Optionally, in a case where 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 may be determined as the resource location of the fourth message.

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

[0186] Optionally, when 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 may be determined jointly based on the resource location of the third message and a time offset. The time offset may be set according to actual needs.

[0187] Optionally, when 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 fourth message can be understood or replaced by Msg3, and a D2R preamble is sent before the sending location of Msg3. The preamble associated with the fourth message can be understood as the D2R preamble.

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

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

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

[0191] The seventh message is a repeated message of the first message, and the time domain configuration information included in the seventh message is different from the time domain configuration information included in the first message. The target behavior includes any one of the following:

[0192] resending the second message based on the seventh message;

[0193] The seventh message is ignored.

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

[0195] Optionally, the AIOT device that considers that the access has failed may resend the second message based on the seventh message, and will continue to receive the third message after resending the second message.

[0196] Optionally, the AIOT device that considers the access successful can directly ignore the seventh message.

[0197] It should be noted that, in some embodiments, to ensure that the repeatedly sent seventh message is effective only for all AIOT devices experiencing access conflicts, the seventh message may 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 devices that have not experienced access conflicts.

[0198] In some embodiments, the resource location of the seventh message does not conflict and can be located before or after the third message of any AIOT device. The AIOT device can determine whether it has an access conflict based on the content of the seventh message. For example, in some embodiments, the seventh message may include at least one of the following:

[0199] Second indication information, where the second indication information is used to indicate the AIOT device that has an access conflict;

[0200] The third indication information is used to indicate an AIOT device for which no access conflict occurs.

[0201] Optionally, in some embodiments, the second indication information and the third indication information may include a random access identifier of the AIOT device. Of course, in other embodiments, the AIOT device may also be indicated by other identification information, which is not further limited here.

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

[0203] resending the second message based on the seventh message when the target condition is met;

[0204] If the target condition is not met, ignoring the seventh message;

[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 AIOT devices where the access conflict occurs include the first device;

[0207] The seventh message includes third indication information, and the third indication information indicates that the first device is not included in the AIOT devices in which no access conflict occurs.

[0208] In an embodiment of the present application, the second indication information indicates that the AIOT device where 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 one of the following:

[0210] at least one time slot allocation, a resource location being one time slot or a plurality of consecutive time slots in the at least one time slot allocation;

[0211] At least one random access opportunity, a resource location being one random access opportunity or a plurality of consecutive random access opportunities of the at least one random access opportunity;

[0212] The number of resource locations indicated by the time domain configuration information is related to the access conflict situation of the AIOT device.

[0213] In an embodiment of the present application, the second device may further adjust the time domain configuration information in the seventh message based on at least one of the results of the AIOT device that experienced access conflicts and the results of the AIOT device that did not experience access conflicts. For example, after considering the number of AIOT devices that experienced conflicts, the number of resource locations that experienced conflicts, the ratio of AIOT devices that experienced conflicts, and the ratio of resource locations that experienced conflicts, if the number of AIOT devices that experienced conflicts is too large or the ratio of resource locations that experienced conflicts is too high, the number of resource locations may be increased. This can reduce the probability of subsequent AIOT device access conflicts.

[0214] In order to better understand the present application, some examples are given below for detailed description.

[0215] Referring to Figure 5a, the resource location indicated by the time domain configuration information is a slot, and the AIOT operation is an inventory operation. As shown in Figure 5a, the following process is included:

[0216] In step 501, the Reader sends an initial broadcast message Msg0 to trigger an inventory of at least one AIoT device. That is, Msg0 can be understood as an inventory request.

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

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

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

[0220] Whether to allow, support or indicate whether Msg1 carries the first transmission container;

[0221] Reader identification information.

[0222] In step 502, the AIoT device receives Msg0 and, on the premise of responding to the inventory request of the first device, determines the resource location and carried content sent by Msg1.

[0223] Optionally, regarding the resource location for sending Msg1, one of the slots may be selected as the slot for sending Msg1 according to the time domain configuration information included in Msg0.

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

[0225] A random access identifier;

[0226] a first transport container;

[0227] Reader identification information.

[0228] In step 503 , the AIOT device sends Msg1 . For example, the AIOT device sends its own Msg1 content in a slot selected by itself or determined based on configuration.

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

[0230] In step 504, the Reader receives Msg1 from at least one AIOT device and determines the resource location and content sent by Msg2, where Msg2 is a response message to one of the at least one AIOT device in response to Msg1.

[0231] Optionally, the resource location for sending Msg2 may be determined based on any of the following methods.

[0232] In method 1, the Msg2 sending location is related to the R2D preamble location that accompanies Msg2. For example, the R2D preamble is sent before the Msg2 sending location, and the Msg2 sending location is indicated based on the detected R2D preamble, as shown in Figure 5b.

[0233] In mode 2, the sending position of Msg2 is related to the sending position of Msg0, for example, determined based on the slot position sent by Msg0 and a time offset. For example, the sending position of Msg2 is equal to the slot position sent by Msg0 plus the first time offset, as shown in Figure 5c.

[0234] In mode 3, the sending position of Msg2 is related to the sending position of Msg1, for example, determined jointly by the slot position sent by Msg1 and a time offset. For example, the sending position of Msg2 is equal to the slot position sent by Msg1 plus the second time offset, as shown in Figure 5d.

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

[0236] The ACK message or NAK message corresponding to the random identifier in Msg1;

[0237] A RAN Temp ID;

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

[0239] Specifically, the ACK information or NAK information here needs to be combined with the random identifier in Msg1 to clarify which AIOT device corresponds to the ACK or NAK. For example, a method of explicit indication: the random identifier in Msg1 of a certain AIOT device is included in the relevant field of the ACK information and sent, which indicates an ACK for the AIOT device; or, the random identifier in Msg1 of a certain AIOT device is included in the relevant field of the NAK information and sent, which indicates a NAK for the AIOT device. For another example, a method of implicit indication by default: the random identifier in Msg1 of a certain AIOT device is not included in the relevant field of the ACK information and sent, which indicates a NAK for the AIOT device; or, the random identifier in Msg1 of a certain AIOT device is not included in the relevant field of the NAK information and sent, which indicates an ACK for the AIOT device.

[0240] In step 505 , Reade sends Msg2. For example, Reade sends Msg2 to each of the at least one AIOT device according to the determined resource location and carried content of Msg2.

[0241] In step 506, the AIOT device determines whether the access is successful or failed. For example, the AIOT device receives Msg2 and determines whether the access process is successful or failed based on the content of Msg2.

[0242] If one of the following conditions is met, the access process is considered successful.

[0243] Condition 1: Msg2 contains the ACK information field and the NAK information field, and the random identifier in Msg1 is included in the relevant fields of the ACK information (explicit indication);

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

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

[0246] Optionally, if the access process is successful, if Msg2 also contains other content, the other content is further validated 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 validation / application; if it belongs to the MAC layer, it is directly validated or applied; if it belongs to an upper layer (above the AS layer, such as the AIOT layer or NAS layer), it is submitted to the upper layer for further validation or application.

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

[0248] Condition 4: Msg2 contains the ACK information field and the NAK information field, and the random identifier in Msg1 is included in the relevant field of the NAK information (explicit indication);

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

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

[0251] Optionally, under the premise that the access process fails, if Msg2 also contains other content, it is directly ignored or discarded.

[0252] Step 507: The AIOT device sends Msg3. For the AIOT device that has successfully connected, the AIOT device sends Msg3 to the Reader.

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

[0254] a first transport container;

[0255] Capability information of AIOT devices.

[0256] The resource location for sending Msg3 can be determined according to any of the following methods.

[0257] Mode 1: The sending position of Msg3 is determined according to the physical layer parameter information of the next D2R transmission (ie, Msg3) indicated by the content carried by Msg2.

[0258] In mode 2, the sending position of Msg3 is related to the sending position of Msg1. For example, it is determined based on the slot position sent by Msg1 and a time offset. For example, the sending position of Msg3 is equal to the slot position sent by Msg1 plus the third time offset, as shown in Figure 5e.

[0259] In mode 3, the sending position of Msg3 is related to the sending position of Msg2. For example, it is determined based on the slot position sent by Msg2 and a time offset. For example, the sending position of Msg3 is equal to the slot position sent by Msg2 plus the fourth time offset, as shown in Figure 5f.

[0260] In mode 4, the Msg3 sending location is related to the D2R preamble location sent along with Msg3. For example, the D2R preamble is sent before the Msg3 sending location, and the Msg3 sending location is determined based on the detected preamble, as shown in Figure 5g.

[0261] In step 508, the Reader sends the first transmission container to the core network device. For example, upon receiving Msg3 sent by the AIOT device, the Reader forwards the first transmission container in Msg3 to the core network device.

[0262] In step 509 , the Reader sends Msg4 . For example, when the Reader receives the second transmission container for a certain AIOT device from the core network 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] Physical layer parameter information for the next D2R transmission (i.e., Msg5).

[0267] Optionally, the AIOT device detects whether there is a Msg4 sent to it based on the ACK information or RAN temp ID in the Msg2. If so, it further parses and processes the Msg4, specifically including: distinguishing further validation or application of other content according to the content indication field.

[0268] It should be noted that Msg2 in the above embodiment is a one-to-one response. In some embodiments, it can also be a one-to-many response. In this case, the resource location of Msg2 can be determined based on the content of Msg0. For example, it can be determined 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) or 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 reference; 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 of Msg2 includes at least one of the following information:

[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 of the next D2R transmission (ie, Msg3).

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

[0274] Optionally, in some embodiments, conflicts may occur during the AIOT device access process. As shown in FIG6 , the process includes the following steps:

[0275] Steps 601 to 603 are the same as steps 501 to 503 , and differ from the above embodiment in that at least two AIOT devices send Msg1 in the same slot (eg, slot_N1 ), resulting in an access conflict.

[0276] In step 604, when the Reader determines that an access conflict occurs between at least two AIOT devices, Msg0 is repeatedly sent. The repeatedly sent Msg0 is different from the previously sent Msg0 in at least part of its content, such as different time domain configuration information.

[0277] Optionally, if the AIOT device receives Msg0 repeatedly sent by the Reader before receiving Msg2, the AIOT device performs at least one of the following actions: stops the ongoing access process; considers the access process failed; jumps to the step of determining the resource location and content sent by Msg0 based on the repeatedly sent Msg0, and re-accesses.

[0278] Optionally, the AIOT device performs at least one of the following actions based on the content of the repeatedly sent Msg0: terminating the ongoing access process; deeming the access process failed; and retrying access based on the repeatedly sent Msg0 by proceeding to the step of determining the resource location and content of the Msg0. For example, the repeatedly sent Msg0 may carry the 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] 7 , an embodiment of the present application further provides an AIOT operation processing method. As shown in FIG7 , the AIOT operation processing method includes:
