[0046] In some embodiments of the first aspect, the first command is further used for counting down of a random number of the second device; and the method further comprises: the first device has not initiated the access, and the first command is ignored.

[0047] Based on the above scheme, if the first device has not initiated the access, the first command can be directly ignored, so as to maintain the discreteness of the multiple devices in determining to send the access based on their own random values, reduce the rush access, and reduce the access congestion.

[0048] In some embodiments of the first aspect, the first device has initiated at least one access, and determining whether to re-initiate the access according to the first command comprises at least one of: the first device has initiated at least one access, and the first command is received to determine to re-initiate the access; the first device has initiated at least one access, and the first command does not carry first information, and it is determined to re-initiate the access; the first information is used to indicate a device to re-initiate the access; the first device has not initiated at least one access, the first command carries first information, and the first information is directed to the first device, and it is determined to re-initiate the access; the first device has not initiated at least one access, the first command carries first information, and the first information is not directed to the first device, and it is determined not to re-initiate the access.

[0049] Based on the above scheme, the case of initiating access according to the specific first access condition is limited to the above examples.

[0050] In some embodiments of the first aspect, the method further comprises: determining an access mode of re-initiating the access; the access mode comprises a contention-based access mode and / or a non-contention-based access mode.

[0051] Based on the above scheme, when re-initiating the access, the access mode may need to be re-determined, and at this time, the access mode of re-initiating the access can be the same as or different from the access mode of the initial access or the previous access. In this way, a suitable access mode can be selected according to needs to complete the access, and different access requirements can be met.

[0052] In some embodiments of the first aspect, the determination of the access mode of re-initiating the access comprises at least one of: determining the access mode of re-initiating the access according to a second access condition of the access initiated by the first device;

The CU-DU structure can split the protocol layers of the access network device, and some of the protocol layers can be controlled by the CU, while the rest or all of the protocol layers can be distributed in the DU and controlled by the CU, but is not limited thereto.

The network element can be virtual or physical. The core network may, for example, include at least one of an evolved packet core (EPC), a 5G core network (5GCN), and a next generation core (NGC).

Further, a plurality of systems can be combined (for example, LTE and NR can be combined).

[0136] The terminal 101 as illustrated in FIG. 1A can be any device that performs wireless communication for a backscattering transmission mechanism.

[0137] As shown in FIG. IB, the backscatter transmission mechanism can be a wireless communication mechanism using the principle of backscatter of radio frequency signals with modulation and transmission technology of extremely low power consumption. The card reader sends a physical layer signal to the ambient IoT device. The physical layer signal can be various alternating current signals such as pulse signals. In some embodiments, the physical layer signal is used to provide energy for the ambient IoT device to transmit signals. Therefore, the physical layer signal can be referred to as an excitation signal or a trigger signal. Exemplarily, when the excitation signal reaches the ambient IoT device, part of it will be reflected, and the ambient IoT device can adjust the matching between the receiving antenna and the impedance according to the information to be sent, enhance the reflection of the incident excitation signal, and modulate the perception data obtained by itself onto the reflected signal to complete the transmission of data. This process is similar to a mirror. Compared with other communication technologies, backscatter transmission does not require complex radio frequency structures, reduces the use of power amplifiers, high-precision crystal oscillators, duplexers, high-precision filters, and other devices, and does not require complex baseband processing. Therefore, the design of the ambient IoT device can be simplified, and the cost of the ambient IoT device node can be greatly reduced. The ambient IoT device is an IoT device that can work in an environment. The environmental energy can include the signal energy of the aforementioned wireless signal, and can also include other environmental capabilities such as geothermal energy and / or light energy.

[0138] Backscatter communication has been widely used in radio frequency identification (RFID) systems, forming many commercial cases. The working principle is that the receiver (generally an RFID reader) sends a radio frequency excitation signal to activate a passive node (generally an RFID electronic tag), and the electronic tag modulates its own information onto the radio frequency signal using backscatter communication. The reader receives the reflected signal of the passive electronic tag and demodulates it to achieve information transmission.

[0139] Currently, FRID technology also has many shortcomings, such as small coverage distance (wireless signals in the communication process will experience double-path fading, so the path loss is large and the effective communication distance is short), single-channel transmission, the need for strict alignment of the tag, no power control, etc. There is a lot of room for improvement in the communication of RFID technology. It is necessary to integrate the third generation partnership project (3 rd Generation Partnership Project, 3GPP) communication technology to improve the wireless communication performance of RFID technology in the field of passive IoT.

[0140] The new type of IoT device targeted by us has the characteristics of low memory, low processing power, low power, small data transmission, and mass deployment. Ambient IoT devices can be maintenance-free and have a long service life (e.g., more than 10 years).

[0141] The new type of IoT device needs to collect radio waves sent by network nodes to obtain energy to drive itself to work. Therefore, before obtaining energy, the IoT device is usually in a "shutdown" state, i.e., a state of being offline. Therefore, the communication system needs to support a data communication mode with shorter transmission time, lower memory consumption, and more convenient terminal management to complete the data communication process as soon as possible.

[0142] The network topology architecture of backscatter transmission can include one of the following:

[0143] Topology architecture 1: As shown in FIG. 1C, ambient IoT devices and access network devices directly perform uplink (UL) and downlink (DL) data transmission;

[0144] Topology architecture 2: As shown in FIG. 1D, ambient IoT devices and access network devices indirectly perform DL and UL data transmission; intermediate nodes (or auxiliary nodes) exist for forwarding, for example, the intermediate node can be a relay, integrated access backhaul (IAB), user equipment (UE), repeater (RP).

[0145] Topology architecture 3: As shown in FIG. 1E, ambient IoT devices and access network devices directly perform DL or UL data reception or transmission; then there are auxiliary nodes on the UL or DL, which are responsible for receiving or transmitting UL or receiving DL data. For example, the auxiliary node can be a relay, an integrated access backhaul (IAB) node, a terminal, a network-controlled repeater (NCR).

[0146] Topology architecture 4: As shown in FIG. 1F, ambient IoT devices and UEs directly perform DL and UL data reception and transmission; the UE is responsible for collecting data and forwarding the collected data to the network side.

[0147] Ambient IOT communication (i.e. communication between ambient IOT devices and base stations (topology architecture 1 as shown in FIG. 1C) and UEs (topology architecture 2 as shown in FIG. 1D) can use spectrum resources in three forms: in-band, guard-band or stand alone.

[0148] In-band is to use the uplink and / or downlink spectrum resources of normal New Radio (NR) communication.

[0149] Guard-band is to use the spectrum resources of the guard band of the DL and / or UL spectrum of normal NR communication.

[0150] Stand alone is to use spectrum resources independent of normal NR communication.

[0151] As shown in FIG. 1G, devices using backscatter transmission mechanism for wireless communication can be divided into three types:

[0152] Device A: no energy storage, cannot independently generate signals and / or amplify signals, can only perform backscatter transmission.

[0153] Device B: has energy storage, cannot independently generate signals, can only perform backscatter transmission. The use of stored energy can include amplification of backscatter signals.

[0154] Device C: has energy storage, can independently generate signals, i.e. has active Radio Frequency (RF) components for transmission.

[0155] It should be noted that each device in FIG. 1G has two grids, where the first grid indicates whether the device has the ability to independently generate signals; the second grid indicates whether the device has the ability to store energy. When the grid of the device is a grid without filling, it means that the device does not have the corresponding ability of the grid; when the grid of the device is a grid with filling, it means that the device has the corresponding ability of the grid.

[0156] In some embodiments, the following constraints are made for ambient IoT devices:

[0157] The first type of device has a peak power consumption of about 1 μW, has energy storage, and an initial Sampling Frequency Offset (SFO) of up to 10X ppm; neither downlink amplification nor uplink amplification is available in the device. The uplink transmission of the device is backscattered on an externally provided carrier;

[0158] The second type of device, with peak power consumption less than or equal to a few hundred μW, has energy storage, and an initial SFO up to 10X ppm; the device has a downlink amplification function and / or an uplink amplification function. The uplink transmission of the device can be generated internally by the device, or backscattered on an externally provided carrier. Wherein, X is determined by the working group.

[0159] In order to support the data transmission of ambient IoT devices, the following functions need to be supported in the network. One device in the network can support one or more functions.

[0160] The function of energy source (ES) is only used for device B and device C.

[0161] The function of downlink transmission (DT) sends indication information to ambient IoT devices, so as to trigger the uplink transmission of ambient IoT devices.

[0162] The function of continuous wave (CW) is only used for device A and device B. Ambient IoT devices realize uplink transmission by backscattering CW. CW is actually also an ES, and ambient IoT devices can receive CW and store energy.

[0163] The function of uplink receiver (UR) receives the uplink information backscattered by ambient IoT devices, or receives the uplink information actively transmitted by ambient IoT devices.

[0164] The device performing the above ES, DT, CW or UR function can be a UE, a repeater or a base station, etc. One device can only support one of the above functions. Alternatively, one device can also support multiple functions at the same time. Alternatively, one device can also support all the above functions at the same time.

[0165] The ambient IoT device can also be called a tag, and the device reading information from the ambient IoT device can also be called a card reader or a card reader, etc.

[0166] In different scenarios, ambient IoT devices can transmit information based on different commands of other devices. Fig. 1H shows the interaction between ambient IoT devices and other devices in the inventory scenario, which can specifically include:

[0167] The card reader selects the tag, specifically by issuing a command to select the tag. For example, the type of the tag is carried in the issued command;

[0168] The reader sends a command, which can include a query command, a query adjust command, or a query repeat command. The command can carry Q. Illustratively, Q can be any positive integer between 0 and 16. Alternatively, Q can be any positive integer between 0 and 32.

[0169] The reader generates a random value based on Q, and stores the generated random value as RN16. A time slot counter counts down according to RN16.

[0170] The reader sends a query repeat-like command.

[0171] The time slot counter decrements by 1.

[0172] The reader sends a query repeat-like command.

[0173] The time slot counter counts down according to RN16.

[0174] The handle transmission and the execution of the access control flow.

[0175] Illustratively, the reader uses the handle as a parameter to access the tag. Step 8: The tag verifies the handle.

[0176] Of course, the above is merely an example of how an IoT device can communicate with other devices, and the specific implementation is not limited to the above example.

[0177] A standard Radio Frequency Identification (RFID) system operates in the frequency band of 860-960 MHz, and is mainly committed to providing a unified method to read data from an RFID tag, write data into the tag, and communicate with the tag.

[0178] In general, the transmission between devices is a half-duplex protocol. That is, only one reader is allowed to send signals or only one tag is allowed to send signals in one transmission.

[0179] Therefore, the reader and the tag do not send signals at the same time.

[0180] Based on the Query command, the reader (reader) configures a Q value for the tag (tag), and based on the Q value, the tag (tag) randomly selects a value in (0, 2 Q-1) random number and save. The tag (tag selected zero immediately reply, select non-zero value then wait for query adjustment (QueryAdjust) command t or query repeat (QueryRep) command. When receiving QueryRep command, the random value is reduced by 1, and so on, until the random value is 0. In the case of random value equal to 0, the tag can feedback data report.

[0181] The current mode, if the tag cannot receive QueryRep, will miss the decrement of the random number. At the same time, the network side cannot repeatedly request data report for the tag.

[0182] As shown in FIG. 2, the embodiment of the present disclosure provides a command processing method, which is executed by the communication system shown in FIG. 1A. The method can include:

[0183] S2101: The second device sends a first command to the first device.

[0184] In some embodiments, the first device can be the environmental Internet of Things device in FIG. 1B. Alternatively, the first device can be the device shown in FIG. 1G, for example, the first device can be the device A, device B or device C in FIG. 1G.

[0185] In some embodiments, the second device can be the card reader in FIG. 1B. Alternatively, the second device can be the access network device or the secondary node in FIG. 1C to FIG. 1F.

[0186] In some embodiments, the first command can be any message sent by the second device to the first device.

[0187] In some embodiments, the first command can be a broadcast message or a groupcast message.

[0188] In some embodiments, the first command includes second information, and the first command is used to instruct the first device to re-initiate access; or the first command does not include second information, and the first command is used to instruct the first device not to re-initiate access. At this time, the first command can carry the second information, or can not carry the second information. That is, the second information is optional content of the first command. That is, in the embodiment of the present disclosure, according to the state of whether the first command carries the second information, it is indicated to the first device whether to need to re-initiate access.

[0189] In some embodiments, the second information includes one of the following:

[0190] A first indication, the first indication is used to instruct the first device to re-initiate access;

[0191] A second indication, the second indication is used to instruct the first device to initiate access.

[0192] In some embodiments, the first indication can be a re-access indication (or referred to as a repeat indication or a retransmit indication), which can specifically indicate to re-initiate an access. In this case, the second indication is not carried by the second command. The second command can be a command that causes the first device to initially access. For example, the second command can be a paging message or an initial trigger message. In some embodiments, the second indication can be carried in the second command to indicate the initial access of the first device. The second device sends the second command to the first device; the second command includes the second indication.

[0193] In some embodiments, the second indication can be a new trigger indication, which can be used to indicate to initiate a new access.

[0194] In some embodiments, the second indication is different from the first indication. If the first indication needs to be carried in the second command, the value of the first indication is a specified value. For example, the first indication is a Boolean variable, the value of the second indication in the second command is false, then the first device will ignore the first indication in the second command. The value of the first indication in the first command is true, then the first device will consider that the second device indicates to re-initiate an access.

[0195] In some embodiments, the first command includes third information; the third information is used to indicate whether the first device re-initiates an access.

[0196] In some embodiments, the third information is a mandatory content of the first command, and the information content of the third information is used to explicitly indicate whether the first device re-initiates an access.

[0197] In some embodiments, the third information includes one of the following;

[0198] a third indication, the first indication is used to indicate whether the first device re-initiates an access;

[0199] a fourth indication, the second indication is used to indicate whether the first device initiates an access; the second indication in the first command is used to indicate whether the first device re-initiates an access; the second indication is different from the first indication;

[0200] a flip indication;

[0201] A fifth indication is used to indicate a number of times of triggering; the first command carries the fifth indication with a value equal to a value of a previous fifth indication received by the first device, and the first command is used to instruct to re-initiate the access; the first command carries the fifth indication with a value not equal to the value of the previous fifth indication received by the first device, and the first command is used to instruct not to re-initiate the access.

[0202] In some embodiments, the third indication can be a re-access indication. Different values of the third indication can be used to indicate whether re-access is needed or not. In some embodiments, the third indication is not carried in the second command, or the third indication is carried in the second command with a specific value, in which case the first device ignores the third indication carried in the second command.

[0203] In some embodiments, the fourth indication can be a new trigger indication. Different values of the fourth indication can be used to indicate whether the first device initiates the access or not. If the fourth indication is carried in the second command, it can be used to instruct the first device to initiate the initial access. If the fourth indication is carried in the first command, it can be used to instruct the first device to re-initiate the access.

[0204] In some embodiments, the flipping indication can also be referred to as the sixth indication. If the value of the sixth indication carried in the current first command is different from the value of the sixth indication carried in the previous first command, the current first command is used to instruct the first device to re-initiate the access. If the value of the sixth indication carried in the current first command is the same as the value of the sixth indication carried in the previous first command, the current first command is used to instruct the first device not to re-initiate the access.

[0205] In some embodiments, the fifth indication can be a trigger indication. For example, the indication indicates the number of times of triggering the access.

[0206] In some embodiments, the first indication, the second indication, the third indication and / or the fourth indication can each include one indication bit, and different values of the indication bit represent different meanings.

[0207] In some embodiments, the fifth indication and the sixth indication can include one or more bits, and the bits can be used to indicate the number of times of the access. For example, the number of bits included in the fifth indication and / or the sixth indication depends on the maximum number of times of the access allowed for the first device in one round of access.

[0208] S2102: Determine whether to re-initiate the access.

[0209] In some embodiments, the first device determines whether to re-initiate the access according to a first access condition of the first device.

[0210] In some embodiments, the first access condition can be a condition indicating whether the first device has initiated the access or not.

[0211] In some embodiments, the first device has initiated at least one access, and determining whether to re-initiate access according to the first command. Illustratively, the first device has initiated at least one access in the current round of interaction (access). In some embodiments, a second command can correspond to a round of access. The second command can be a command that triggers the first device to initiate an access. Illustratively, the second command can be a paging command or an initial trigger message.

[0212] In some embodiments, the first device has not initiated an access, and determining not to re-initiate access.

[0213] The first device has initiated at least one access, and determining whether to re-initiate access according to the first command comprises at least one of:

[0214] The first device has initiated at least one access, and receiving the first command determines to re-initiate access.

[0215] The first device has initiated at least one access, and the first command does not carry first information, and determining to re-initiate access. The first information is used to indicate a device that re-initiates an access.

[0216] The first device has not initiated at least one access, the first command carries first information, and the first information is directed to the first device, and determining to re-initiate access.

[0217] The first device has not initiated at least one access, the first command carries first information, and the first information is not directed to the first device, and determining not to re-initiate access.

[0218] In some embodiments, the first information can be any information that can identify a device. For example, the first information can be a random number generated by a device in a round of interaction, etc. The random number can be originally used by a corresponding device to determine a time slot to initiate an initial access, etc. For another example, the first information can also be any device identification. Illustratively, the first information can be an Electronic Product Code (EPC) or a part of the EPC.

[0219] In some embodiments, the first command does not carry the first information indicating which device to access. In this case, the first device reinitiates the access if the first command is received when the first device has initiated the access at least once. In this case, the first device reinitiates the access if the first command is received when the first device has initiated the access at least once in the current round and all the access attempts have failed. In yet another case, the first device reinitiates the access if the first command is received when the first device has initiated the access at least once in the current round and the data transmission after the access has not been completed.

[0220] In some embodiments, the first command carries the first information. In this case, the first device determines whether to reinitiate the access according to the first information. For example, the first information is directed to the first device, and the first device determines to reinitiate the access. For another example, the first information is not directed to the first device, and the first device determines not to reinitiate the access. For example, the first information can be used to indicate one or more devices that need to reinitiate the access. For example, the first information can be a group identifier of a device group or a device identifier of a single device.

[0221] S2103: determining an access mode for reinitiating the access.

[0222] In some embodiments, the access mode includes a contention-based access mode and / or a non-contention-based access mode.

[0223] In some embodiments, the S2103 is an optional step. For example, the protocol or the device setting of the first device can be configured to always use the contention-based access mode, and thus the step can be skipped.

[0224] In some embodiments, the first device determines to reinitiate the access and determines the access mode for reinitiating the access.

[0225] In some embodiments, the first device can use a 2-step or 4-step random access procedure to access the second device. In the 4-step random access procedure, the access messages can include a first message, a second message, a third message, and a fourth message. For example, the first message can be sent by the device initiating the access, and the second message can be sent by the accessed device in response to the first message. The third message can be sent by the device initiating the access. The fourth message can be sent by the accessed device in response to the third message. In some embodiments, the fourth message can be sent by the accessed device in response to the third message.

[0226] In some embodiments, the first message can comprise a random number for the access. Illustratively, the random number can be used to point to the device that initiates the access. The third message can comprise a device identity of the device that initiates the access. Illustratively, the device identity can comprise an EPC or a MAC address of the device, or an international mobile equipment identity, etc. In this way, if the access initiated by the first device fails, the second device can receive part of the information of the first device, and the second device can indicate, by carrying the first information in the first command, that the first device can facilitate the current second device to have received the message in the random access procedure according to the information type of the first information in the first command.

[0227] In some embodiments, the access mode is determined according to a second access condition of the access initiated by the first device. In some embodiments, the second access condition can be used to indicate an abort phase, an access progress, or a failure cause of the historical access initiated.

[0228] Illustratively, the second access condition can indicate at least one of the following:

[0229] whether the Msgl sent by the first device is successfully received by the second device;

[0230] whether the first device has received the Msg2;

[0231] whether the first device has sent the Msg3;

[0232] whether the second device has received the Msg3;

[0233] whether the first device has received the Msg4 sent by the second device.

[0234] In some embodiments, the first device has sent the message Msgl to the second device and has not received the Msg2 sent by the second device, and the access mode is determined as the contention-based access.

[0235] In some other embodiments, the first device has sent the Msgl to the second device and has received the Msg2 sent by the second device, and the access mode is determined as the contention-based access or the non-contention-based access.

[0236] In some embodiments, the access mode is determined according to the information type of the first information carried in the first command.

[0237] In some embodiments, the access mode is determined according to a type of the first information carried by the first command in a case that the first command carries the first information. For example, the first information is a random number directed to the first device, and the access mode is determined to be a contention-based access mode or a contention-free access mode. For another example, the first information is a device identifier of the first device, and the access mode is determined to be a contention-free access mode. If the first information is the device identifier of the first device, it indicates that the second device has successfully received the first message and the third message initiated by the first device to access, but the first device has not successfully accessed due to temporary lack of resource allocation or the like, or the first device has successfully accessed but the data transmission is not completed before the access is disconnected. In order to achieve timely data transmission or improve the access success rate of the first device, the contention-free access mode is determined to be used to complete the re-access indicated by the first indication.

[0238] In some embodiments, the access mode is determined according to a type of the first command.

[0239] In some embodiments, the first device sends commands of multiple types. Different types of first commands can be used to perform different functions.

[0240] In some embodiments, the first command is of a first type, and the access mode is determined to be a contention-based access mode. For example, the first type of first command is a command that causes the device to perform countdown of a random number. For example, the first type of message can be a query repetition command. For example, the first type of message can be a query repetition (QueryReplike) command. That is, the first type of message can be similar to but not exactly the same as the query repetition command, or the first type of message can be similar to but not exactly the same as the message format and / or transmission manner of the query repetition command.

[0241] The first command is of a second type, and the access mode is determined to be a contention-free access mode. For example, the first command of the second type is a command that causes the device to initiate initial access. For example, the second type of message can be a paging message or an initial trigger message. For example, the second type of message can be a message carrying a parameter for the first device to generate a random number. For example, the second type of message can be a message carrying a time slot index. The random number is generated based on the time slot index. For another example, the second type of message can be a message carrying a Q value. The random number can be any value from 0 to 2 Q -1.

[0242] S2104: The first device re-initiates access.

[0243] In some embodiments, the first device determines to re-initiate the access, and re-initiates the access.

[0244] In some other embodiments, the first device determines to re-initiate the access, and re-initiates the access according to the determined access mode.

[0245] S2105: The first device ignores the first command.

[0246] In some embodiments, the first device receives the first command in a case that the first device has not initiated the access, and ignores the first command.

[0247] In some embodiments, the first device receives the first command in a case that the first device has initiated the access at least once, and the first information carried by the first command does not point to the first device, and ignores the first command.

[0248] In some embodiments, the first command has multiple functions, for example, the first command indicates whether to re-initiate the access, and also indicates the first device to perform a countdown of a random number, and the purpose of ignoring the first command is not to perform the countdown of the random number. Here, ignoring the first command can be understood as not performing other operations or processes triggered by the first command.

[0249] As shown in FIG. 3, the embodiment of the present disclosure provides a command processing method, which is performed by a first device. The method can include:

[0250] S3101: Receiving a first command.

[0251] In some embodiments, the first device receives the first command from a second device.

[0258] In some embodiments, the manner of determining whether to re-initiate the access can refer to S2104 of the corresponding embodiment of FIG. 2.

[0259] S3105: ignore the first command.

[0260] In some embodiments, the way of determining whether to re-initiate the access can refer to S2105 of the corresponding embodiment of FIG. 2.

[0261] It is worth noting that in the case where the first device performs S3105, S3103 and S3104 will not be performed. In some cases, S3103 is an optional step, for example, when the contention-based access mode or the non-contention-based access mode is adopted by default, even if it is determined to re-initiate the access, S3103 does not need to be performed specifically.

[0262] As shown in FIG. 4, the embodiment of the present disclosure provides a command processing method, which is performed by a second device. The method can include:

[0263] S4101: send a first command.

[0264] In some embodiments, the related description of the first command can refer to the related description of the corresponding embodiment of FIG. 2, which will not be repeated here.

[0265] In some embodiments, the optional implementation of the second device sending the first command can refer to S2101 of the corresponding embodiment of FIG. 2.

[0266] The embodiment of the present disclosure provides a method, which allows the network side to trigger the device to initiate the access process again when the device does not receive the random access trigger command or in the case of random access failure.

[0267] Scheme 1:

[0268] First, the network side issues an initial message or a paging message to trigger at least one device to respond to the network, and the device randomly selects a time slot index based on the network side configuration. The network side issues a command, such as a QueryRep like command, to trigger the device to decrease the time slot index (i.e., the count value of the time slot counter) by one. If the count value of the time slot counter decreases to 0, the access process is triggered. In order to repeatedly trigger the access process for the devices in the same time slot, the network side can repeatedly issue the QueryRep like message. If the QueryRep is repeatedly sent, an indication information is carried in the QueryRep message, which can be one of the following:

[0269] Option 1: repeated sending indication; for example, 1 bit, if it is the first sending for a time slot, the indication is not sent or set to false, if it is repeated sending for the same time slot, the indication is set to true.

[0270] Option 2: minus 1 indication or new trigger indication (NTI), for example, 1 bit, if it is the first transmission for a time slot, the indication is set to true; if it is a repeated transmission for the same time slot, the indication is not sent or set to false.

[0271] Option 3: flip indication, for example, 1 bit, if the value of the indication is different from the previous one, it is a new trigger, then perform the minus 1 operation of the time slot counter, otherwise do not perform the minus 1 operation.

[0272] Option 4: indicate the number of new triggers, if the value of the indication received by the tag is the same as the previous one, it means retransmission, otherwise it means new trigger, perform the minus 1 operation.

[0273] Example 1: for a device that has not triggered (Contention Based access, CB) access, if a QueryRep command is received, then:

[0274] Option 1: repeated transmission indication; for example, 1 bit, if it is the first transmission for a time slot, the indication is not sent or set to false, if it is a repeated transmission for the same time slot, the indication is set to true.

[0275] Option 2: minus 1 indication or new trigger indication (NTI). For example, the NTI is 1 bit, if it is the first transmission for a time slot, the indication is set to true; if it is a repeated transmission for the same time slot, the indication is not sent or set to false.

[0276] Option 3: flip indication. For example, the flip indication can be 1 bit, if the value of the indication is different from the previous one, it is a new trigger, then perform the minus 1 operation of the time slot counter, otherwise do not perform the minus 1 operation.

[0277] Option 4: number of times indication bit, the number of times indication bit is used to indicate the number of new triggers, if the value of the indication received by the tag is the same as the previous one, it means retransmission, otherwise it means new trigger, perform the minus 1 operation.

[0278] For the above four options, if it is a repeated trigger access, the time slot counter is not minus 1, otherwise minus 1.

[0279] Example 2:

[0280] For the device which triggers CB access, the message 1 (Msg1) is sent, the Msg1 can include RN, but the Msg2 is not received, at this time, from the perspective of the network side, the Msg3 containing the device ID is not received, the network side issues a query repetition (QueryRep) command. The query repetition (QueryRep) command contains the following indications, or; for the device which triggers CB access, the Msg1 is sent. The Msg1 can include the device ID, but the Msg2 is not received, at this time, from the perspective of the network side, the Msg1 containing the device ID is not received, the network side issues a query repetition (QueryRep) command. The query repetition (QueryRep) command contains the indication of one of the following options:

[0281] Option 1: Repeat transmission indication, set to true. The device reinitiates the random access (Radio Access Channel, RACH), if the device just triggers the CB access process. If false, do not access the network side, wait for the network side new trigger command.

[0282] Option 2: Reduce 1 indication or new trigger indication (NTI), for example, 1 bit, set to true, then do not access the network side, wait for the network side new trigger command. If false, the device reinitiates the random access (Radio Access Channel, RACH), if the device just triggers the CB access process.

[0283] Option 3: Flip indication, for example, 1 bit, if the value of the indication is different from the previous one, it is a new trigger, then do not access the network side, wait for the network side new trigger command. If the value of the indication is the same as the previous one, it means retransmission, then the device reinitiates the RACH, if the device just triggers the CB access process.

[0284] Option 4: Indicate the number of new triggers, if the value of the indication received by the tag is the same as the previous one, it means retransmission, then the device reinitiates the RACH, if the device just triggers the CB access process.

[0285] Otherwise, it means new trigger, then do not access the network side, wait for the network side new trigger command.

[0286] For the above scheme, the network side can carry data book (Ramdom Number, RN) in the query repetition (QueryRep), and the carrying only means retransmission, which means that the device corresponding to the specified RN triggers reaccess.

[0287] Example 3: For the device which triggers CB access, sends Msg1: RN, receives Msg2, and sends Msg3 containing the device ID, if the network side does not receive Msg3, the network side issues a QueryRep command, the QueryRep command contains the following indication, and the following operation or option can be included at least one of:

[0288] Option 1: Repeat the indication and set it to true. Then the device reinitiates RACH if the device just triggered the CB access process. If false, do not access the network side again, and wait for the new trigger command of the network side.

[0289] Option 2: Reduce 1 indication or new trigger indication, NTI, for example, 1 bit, set it to true, then do not access the network side again, and wait for the new trigger command of the network side. If false, the device reinitiates RACH if the device just triggered the CB access process.

[0290] Option 3: Flip the indication, for example, 1 bit, if the value of the indication is different from the previous one, it is a new trigger, then do not access the network side again, and wait for the new trigger command of the network side. If the value of the indication is the same as the previous one, it means retransmission, then the device reinitiates RACH if the device just triggered the CB access process.

[0291] Option 4: Indicate the number of new triggers, if the value of the indication received by the tag is the same as the previous one, it means retransmission, then the device reinitiates RACH if the device just triggered the CB access process.

[0292] Otherwise, it means new trigger, then do not access the network side again, and wait for the new trigger command of the network side.

[0293] For the above scheme, the network side can carry the device ID in the QueryRep command, and only indicate retransmission, which means triggering the device corresponding to the specified RN to re-access.

[0294] 1. The network side re-triggers the target device to access, for example, triggers CB access in the current access occasion.

[0295] 2. The network side re-triggers the target device to access, for example, triggers CF access nested in the current access occasion.

[0296] 3. An indication in the R2D command indicating whether it is a new trigger or a retransmission trigger.

[0297] As shown in FIG. 5A, the command processing method can include:

[0298] The reader sends a ping message:

[0299] Randomly select a time slot index, the tag selects a random number for time slot counting;

[0300] The reader sends a query repeat similar command;

[0301] The tag counts down according to the received query repeat similar command, for example, the time slot counter decreases by 1 for each received query repeat similar command;

[0302] If the countdown reaches 0, the tag sends a random number (RN) to the reader to initiate access.

[0303] The tag CB access fails.

[0304] The tag receives a query repeat similar command from the reader.

[0305] The reader sends a query repeat command to the tag, which indicates repeated access, for example, if the query repeat similar command includes a first indication, the tag ignores the query repeat similar command. If the tag reinitiates access, the tag sends an RN to the reader, and receives an ACK sent by the reader to the tag. After receiving the ACK sent by the reader, the tag sends an EPC and an RN to the reader. After completing the access, data transmission is performed.

[0306] If the query repeat similar command does not include the first indication, the tag counts down by 1.

[0307] As shown in FIG. 5B, the command processing method can include:

[0312] If the countdown of the time slot counter reaches 0, the tag sends an RN to the reader;

[0313] The reader sends an ACK to the tag;

[0314] The tag sends an EPC and an RN to the reader. The EPC is a device identification of the tag.

[0315] The reader receives the EPC and the RN fails.

[0316] Tag CB access failure.

[0317] Tag receives a query repeat similar command from the reader. The query repeat similar command indicates a repeat access, for example, if the query repeat similar command includes a first indication, the tag ignores the query repeat similar command. If the tag reinitiates access, the tag sends an RN to the reader, and the reader sends an ACK to the tag. After receiving the ACK from the reader, the tag sends an EPC and RN to the reader. Data transmission occurs after the access is completed.

[0318] If the query repeat similar command does not include the first indication, the tag decrements a count down by 1.

[0319] The tag sends an RN to the reader. The reader sends an ACK of the RN to the tag.

[0320] The tag sends an EPC and RN to the reader.

[0321] Data transmission between the tag and the reader.

[0322] As shown in FIG. 5C, the command processing method can include:

[0323] The reader sends a ping message:

[0324] Randomly selects a time slot index, for example, the tag selects a random number for time slot counting.

[0325] The reader sends a query repeat command.

[0326] The tag decrements a count down based on receiving the query repeat command; if it is a generic query repeat similar command, the time slot counter is decremented by 1.

[0327] If the time slot counter decrements to 0, the tag sends an RN to the reader.

[0328] Tag CB access failure.

[0329] Tag receives a query repeat similar command from the reader.

[0330] If the query repeat similar command indicates a repeat access, the tag sends an RN to the reader; the repeat initiation of access is achieved by the initiation of the RN.

[0331] The reader sends an ACK of the RN to the tag; the tag sends an EPC and RN to the reader.

[0332] Reader EPC reception failure, sends a query repeat similar command to the tag, indicating a repeat access.

[0333] The tag sends RN to the reader. The reader sends ACK of RN to the tag.

[0334] The tag sends EPC and RN to the reader.

[0335] Data transmission between the tag and the reader.
