[0002] Currently, in traditional Radio Frequency Identification (RFID) Backscatter Communication (BSC) systems, multiple BSC devices (i.e., electronic tags) can obtain the opportunity to send data through a contentious access process, such as random time access based on Q value and temporary identifier verification based on 16-bit random numbers.

[0003] However, in the above method, the BSC device needs to continuously send a 16-bit temporary identifier during the contention process so that the temporary identifier can be correctly and uniquely identified by the reader. Since the currently used temporary identifier length consumes a large amount of communication and storage resources, and the fixed temporary identifier length also makes the access mechanism inflexible, and if the temporary identifier length is insufficient, multiple BSC devices may easily generate the same temporary identifier, resulting in a high probability of collision and thus reducing the communication success rate. Therefore, how to configure temporary identifiers for BSC devices is an urgent problem to be solved. Summary of the Invention

[0035] The following explanations and descriptions will cover some concepts and / or terms involved in the information indication methods, apparatuses, target devices, and storage media provided in the embodiments of this application.

[0036] Backscatter communication refers to the use of radio frequency signals from other devices or the environment by backscatter communication devices (hereinafter referred to as BSC devices) to modulate signals and transmit information. BSC devices can be tags in traditional RFID or passive Internet of Things (IoT) user equipment (UE).

[0037] BSC devices control the reflection coefficient Γ of the circuit by adjusting their internal impedance, thereby changing the amplitude, frequency, and phase of the incident signal to achieve signal modulation.

[0038] It should be noted that the reflection coefficient of a signal can be characterized as:

[0039] Where Z0 is the characteristic impedance of the antenna, and Z1 is the load impedance. If we assume the incident signal is S... in (t), then the output signal is Therefore, by properly controlling the reflection coefficient, corresponding amplitude modulation, frequency modulation, or phase modulation can be achieved.

[0040] Currently, typical backscatter communication architectures can be divided into monostatic and bistatic systems.

[0041] Monobase system

[0042] Figure 2 A schematic diagram of a monostatic backscatter communication system is shown, a typical example of which is the traditional RFID system, such as... Figure 1 As shown, an RFID system includes a Base Station Controller (BSC) device (e.g., a Tag) and a reader / writer. The reader / writer contains an RF source and a BSC receiver. The RF source generates an RF signal to power the BSC device. The BSC device sends the backscattered RF signal to the BSC receiver in the reader / writer. The BSC receiver receives the RF signal and demodulates it. Since the RF source and the BSC receiver are in the same device, such as the reader / writer described above, this system is called a monostatic backscatter communication system.

[0043] In monostatic backscatter communication systems, the RF radio frequency signal transmitted from the BSC device experiences a double near-far effect due to signal attenuation during the round trip, resulting in significant signal energy attenuation. Therefore, monostatic systems are generally used for short-range backscatter communication, such as traditional RFID systems.

[0044] Bibase system

[0045] Figure 3 A schematic diagram of a bistatic backscatter communication system is shown, such as... Figure 3 As shown, the RF source and BSC receiver in a bistatic system are separate. Therefore, the bistatic system avoids the problem of large round-trip signal attenuation. Furthermore, by strategically placing the RF source, the performance of the backscatter communication system can be further improved.

[0046] Information transmission between RFID readers and tags

[0047] Figure 4 A schematic diagram of a reader / writer and tag status is shown, such as... Figure 4 As shown, in the current ISO 18000-6c defined EPC C1G2 RFID system, a series of reader control commands and tag statuses are defined, such as... Figure 4 As shown in Tables 1 and 2, in actual use, the reader sends control commands to the tag, the tag receives the control commands, thereby changing the tag's state. At the same time, the tag can reply with corresponding data to the reader based on the control commands and its current state.

[0052] Table 2: Tag Status

[0053] Single-tag (contention-free) send / receive flowchart

[0054] Figure 5 This diagram illustrates the process of receiving and sending data for a single tag (i.e., in a contention-free scenario), as shown below. Figure 5 As shown, in inventory mode, after the reader sends a query command (Query), the tag responds (Reply). Taking Reply as RN16 as an example, the tag generates a 16-bit random number and sends it to the reader. Then, the reader sends the sequence to the tag via an ACK command. After the tag successfully verifies RN16 in the ACK, it can send subsequent data to the reader.

[0055] Multi-Tag Competitive Access Process

[0056] Figure 6A schematic diagram of a multi-tag contention access process is shown, such as... Figure 6 As shown, in inventory mode, the multi-tag contention access process includes the following steps 1 to 13.

[0057] Step 1: The reader sends a Select command to select the tag that needs to be inventoried.

[0058] Step 2: The reader sends a Query command to initiate an inventory count. The Query command specifies a Q value.

[0059] Step 3: Generate a random integer for each tag as the initial value for the counter.

[0060] The random integer takes values ​​in the range [0, 2]. Q -1]

[0061] Step 4: Check if the Tag counter is 0.

[0062] Step 5a: If the counters of at least two tags are 0, the tag with a counter of 0 sends a Reply containing a randomly generated 16-bit random number, denoted as RN16.

[0063] Step 5b: When the counter for untagged items is 0, the reader sends a QueryRep command.

[0064] Step 6a: If the reader successfully decodes RN16, the reader sends an ACK command, which includes RN16 and a 2-bit command field.

[0065] Step 6b: If the reader fails to decode RN16, the reader sends a NAK command.

[0066] Step 7: Tag receives the ACK and checks whether the RN16 contained in the ACK is the RN16 sent previously.

[0067] Step 8a: If RN16 is correct, the Tag that verifies RN16 sends the data that needs to be reported to the reader, such as PC, XPC, EPC or other data, to indicate that the inventory of the Tag is complete.

[0068] Step 8b: In the case of an RN16 error, the Tag that checks for the RN16 error sets its own counter to the maximum value.

[0069] Step 9: If the tag that received the NAK command sent a Reply in the previous adjacent time sequence, then the tag sets its own counter to the maximum value.

[0070] Step 10: The tag that receives the QueryRep command decrements its own counter by 1.

[0071] Step 11: The reader can send a QueryAdjust command to reconfigure a Q value.

[0072] Step 12: For tags that have received the QueryAdjust command and have not completed the inventory count, randomly select an integer as the counter.

[0073] The integer in question ranges from [0, 2]. Q -1].

[0074] Step 13: Repeat steps 4-12 until all tags are inventoried.

[0075] It should be noted that if there are exactly more than one tag with a counter of 0, and they happen to use the same RN16, then these tags will all successfully check for ACK in step 7 and send data simultaneously in the future, causing the reader / writer to fail to decode. This situation is called contention access and temporary identifier conflict.

[0076] As can be seen from the above, the multi-tag competitive access of RFID consists of two parts: one is random time access based on Q value, and the other is temporary identification verification based on RN16. In the process of competing for access opportunities, the tag needs to repeatedly send RN16 until the RN16 is correctly and uniquely identified by the reader.

[0077] Therefore, using a fixed-length temporary identifier makes the entire access mechanism inflexible. On the one hand, when the number of BSC devices is small or the communication reliability requirements are not high, using an excessively long temporary identifier requires a large amount of communication and storage resources, which is particularly serious for BSC systems with weak storage capacity and low data rates. On the other hand, when the number of BSC devices is large or the communication reliability requirements are high, insufficient temporary identifier length can easily lead to multiple BSC devices generating the same temporary identifier, resulting in a high probability of collisions and subsequent communication failures.

[0078] To address the contention-based access process in backscatter communication, this application proposes a method for indicating the length of a temporary identifier for a BSC device. This application defines various methods for indicating the length of temporary identifiers, as well as reference parameters and methods for determining the length of temporary identifiers. Through flexible configuration of the temporary identifier length, the efficiency of BSC device access and the flexibility to meet communication needs in different scenarios are improved.

[0079] It should be noted that the information indication method provided in this application embodiment can be implemented in the existing inventory process defined by the ISO 18000-6c RFID system, and is also applicable to inventory processes or data reading processes defined by other systems. The information indication method provided in this application embodiment is illustrated using the existing inventory process defined by the ISO 18000-6c RFID system as an example; inventory processes or data reading processes defined by other systems are also within the scope of protection of this application embodiment. The information indication method provided in this application embodiment can be applied to all backscatter communication systems, including RFID, LTE, NB-IoT, NR, IEEE 802.11 evolution systems, etc.

[0080] The information indication method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0081] Example 1

[0082] This application provides an information indication method. Figure 7 A flowchart illustrating an information indication method provided in an embodiment of this application is shown. Figure 7 As shown, the information indication method provided in this application embodiment may include the following step 201.

[0083] Step 201: The target device sends the first information to the backscatter communication BSC device.

[0084] In this embodiment of the application, the first information is used to indicate the length of the temporary identifier of the BSC device; wherein, the temporary identifier is used to characterize the temporary identity identifier of the BSC device for communication or session.

[0085] In this embodiment, the temporary identifier is used to characterize the BSC device when competing for access to the channel.

[0086] Optionally, in the embodiments of this application, the target device may be an access network device (e.g., a base station), a UE, or a dedicated reader / writer.

[0087] It should be noted that the embodiments of this application are illustrated using a reader / writer as an example. Other types of devices are also within the scope of protection of the embodiments of this application.

[0088] Optionally, in this embodiment of the application, the BSC device can be a traditional RFID tag, a passive / semi-passive / active IoT device, etc.

[0089] It should be noted that the embodiments in this application are illustrated using a traditional RFID tag as an example. Other types of BSC devices are also within the scope of protection of the embodiments in this application.

[0090] Optionally, in the embodiments of this application, the form of the temporary identifier includes, but is not limited to, a random number (RN), a wireless network temporary identifier (RNTI), a device ID, a tag ID, a product ID, a session ID, an application ID, a user ID, a physical layer address, a data link layer address, a network layer address, an IP address, and a MAC address.

[0091] Optionally, in this embodiment of the application, the first information is included in the first target information and carried in a first manner.

[0092] Optionally, in the embodiments of this application, the first target information is at least one of the following: dedicated control command, RRC signaling, DCI, SCI, physical frame preamble sequence; the first mode includes at least one of the following: dedicated radio signal waveform, PDSCH, PDCCH, PSCCH, PSSCH, MAC CE, physical frame.

[0093] Optionally, in this embodiment, the dedicated control command can be a Select command and a Query command, or a new command formed by combining the Select command and the Query command. This command can be used to select the tag that needs to be inventoried and start a round of inventory counting.

[0094] Optionally, in this embodiment of the application, the target device can indicate the Q value of contention access and the length of the temporary identifier used (e.g., denoted as x, in bits) through the command in the first target information.

[0095] Optionally, in the embodiments of this application, the first information can directly indicate x, for example, using 5 bits to represent the length range 1-32; or, the first information can indicate some optional values ​​of x, for example, using 2 bits to represent 4, 8, 16, 32 (e.g., "00"→4; "01"→8; "10"→16; "11"→32); or, the first information can jointly encode the Q value and x, for example:

[0096] 00 Q1 x1 01 Q2 x2 10 Q3 x3 11 Q4 x4

[0097] Optionally, in this embodiment of the application, the target device may indicate the length of the temporary identifier of the BSC device by means of explicit indication or implicit indication; wherein, explicit indication may refer to step 201a below, and implicit indication may refer to step 201b below.

[0098] Optionally, in the embodiments of this application, step 201 can be implemented by step 201a or step 201b as described below.

[0099] Step 201a: The target device carries the temporary identifier length information of the BSC device or the bit information corresponding to the temporary identifier length information of the BSC device in the first information and sends the first information to the BSC device.

[0100] Step 201b: The target device carries the temporary identifier length information of the BSC device in the first information and sends the first information to the BSC device. The temporary identifier length information of the BSC device is used to indicate the optional value of the temporary identifier length of the BSC device.

[0101] Optionally, in this embodiment of the application, the preset rule is the rule agreed upon by the BSC device.

[0102] This application provides an information indication method in which a target device sends first information to a backscatter communication BSC device. The first information indicates the length of the temporary identifier of the BSC device. The temporary identifier is used to characterize the temporary identity of the BSC device for communication or session. Since the target device can define various indication methods for the length of the temporary identifier and define reference parameters for the length of the temporary identifier, the target device can improve the access efficiency of the BSC device by flexibly configuring the length of the temporary identifier.

[0103] Optionally, in this embodiment of the application, before step 201 above, the information indication method provided in this embodiment of the application further includes step 301 as follows.

[0104] Step 301: The target device determines the first information based on the second information.

[0105] In this embodiment of the application, the second information includes at least one of the following: communication reliability requirement information, temporary identifier length information supported by the BSC device, temporary identifier length information required by the BSC device, effective communication rate requirement information, and number of BSC devices.

[0106] Optionally, in this embodiment of the application, the target device can determine the length of the temporary identifier of the BSC device using six methods based on the second information.

[0107] Optionally, in the embodiments of this application, Method 1: The target device determines the length of the temporary identifier of the BSC device based on the length of the temporary identifier of the pre-agreed tag; Method 2: The target device determines the length of the temporary identifier of the BSC device based on the length of the temporary identifier supported by all tags; Method 3: The target device uses the length of the temporary representation expected to be used by the tag as the length of the temporary identifier of the BSC device; Method 4: The target device uses the length of the temporary identifier that meets the communication reliability requirements as the length of the temporary identifier of the BSC device; Method 5: The target device uses the length of the temporary identifier that meets the effective communication rate requirements as the length of the temporary identifier of the BSC device; Method 6: The target device combines Method 2 to Method 5, selects a temporary identifier length that meets some or all of the requirements, and determines the length of the temporary identifier of the BSC device.

[0108] Optionally, in the embodiments of this application, the above-mentioned communication reliability requirement is the probability of temporary identifier conflict or the probability of contention for access and the probability of temporary identifier conflict, etc.

[0109] Optionally, in this embodiment, the aforementioned temporary identifier conflict probability refers to the probability that at least two BSC devices generate the same temporary identifier. The aforementioned contention for access and temporary identifier conflict probability refers to the probability that at least two BSC devices simultaneously access the radio channel and generate the same temporary identifier.

[0110] It should be noted that if the tag generates x 0 / 1 bits randomly as a temporary identifier; or generates X (where X≥x) 0 / 1 bits and then truncates x bits as the temporary identifier, then the probability that at least two tags generate the same temporary identifier (i.e., the probability of temporary identifier collision) is:

[0111]

[0112] Where n represents the number of tags, and x represents the length of the temporary identifier. If n is known, and the maximum temporary identifier collision probability is given... At that time, we can obtain the following based on equation (1): The feasible temporary identifier length is determined, and one of them is selected.

[0113] It should be noted that, when the tag uses x randomly generated 0 / 1 bits as a temporary identifier; or, when generating X (where X≥x) 0 / 1 bits and then truncating x bits as a temporary identifier, the probability that at least two tag counters are simultaneously 0 (i.e., simultaneously accessing the wireless channel) and using the same temporary identifier (i.e., the probability of contention for access and temporary identifier collision) is as follows:

[0114]

[0115] Where Q is the Q value defined in RFID 18000-6c. If n is known, and given the maximum contention for access and the probability of temporary identifier collision... At that time, we can obtain the following based on equation (2): The feasible temporary identifier length is determined, and one of them is selected.

[0116] It should be noted that, considering only the effective communication rate when the Tag successfully accesses the channel, and assuming the transmission rate from the Tag to the reader is R bps, and the data length to be reported to the reader is D bits, the effective communication rate of the Tag can be expressed as follows:

[0117]

[0118] The ACK contains a temporary identifier and a 2-bit command field. This is given if R and D are known, and a minimum effective communication rate is specified. At that time, we can obtain the following based on equation (3): The feasible temporary identifier length is determined, and one of them is selected.

[0119] Optionally, the information indication method provided in this application embodiment further includes the following step 202.

[0120] Step 202: The target device sends third information to the BSC device.

[0121] In this embodiment of the application, the third information is used to instruct the BSC device on the time of data transmission and reception.

[0122] Optionally, in the embodiments of this application, step 202 can be implemented by step 202a or step 202b as described below.

[0123] Step 202a: The target device carries the time information of data transmission and reception of the BSC device in the third information and sends the third information to the BSC device.

[0124] Step 202b: The target device, according to preset rules, carries the data transmission and reception information of the BSC device in the third information and sends the third information to the BSC device.

[0125] In this embodiment of the application, the data transmission and reception information of the BSC device is used to indicate the correspondence between the data transmission and reception time information of the BSC device and the length of the temporary identifier of the BSC device.

[0126] Optionally, in this embodiment of the application, the target device may use implicit or explicit indication to instruct the BSC device to provide time information for data reception.

[0127] Implicit indication refers to the target device matching the temporary identifier length information of the BSC device with the time information according to the agreed rules; explicit indication refers to the target device sending third information to the BSC device, which is used to instruct the BSC device on the time information for data transmission and reception.

[0128] Optionally, in this embodiment, since the time and energy required for the Tag to send a temporary identifier and receive an ACK may vary depending on the length of the temporary identifier used by the system, a set of matching timelines is simultaneously indicated to the Tag when the reader configures the length of the temporary identifier, and this set of timelines is used for data transmission and reception in subsequent communication processes.

[0129] Optionally, in this embodiment of the application, the third information is included in the first target information and carried in a first manner.

[0130] Optionally, in the embodiments of this application, the first target information is at least one of the following: dedicated control command, RRC signaling, DCI, SCI, physical frame preamble sequence; the first mode is at least one of the following: dedicated radio signal waveform, PDSCH, PDCCH, PSCCH, PSSCH, MAC CE, physical frame.

[0131] Optionally, the information indication method provided in this application embodiment further includes the following step 401.

[0132] Step 401: The target device receives the fourth message sent by the BSC device.

[0133] In this embodiment of the application, the fourth information is used to indicate the length of the temporary identifier that the BSC device supports and / or requires.

[0134] Optionally, in this embodiment, the fourth information carries temporary identifier length information of the BSC device or bit information corresponding to the temporary identifier length information supported and / or required by the BSC device; or, the fourth information indicates an optional value for the temporary identifier length of the BSC device.

[0179] Example 3

[0180] This application provides a configuration interaction method, which may include the following steps 11 to 20, 21 to 24, and 31 to 35.

[0181] Step 11: The target device (hereinafter referred to as a reader / writer) sends a first command to at least one BSC device (hereinafter referred to as a Tag).

[0182] The first command is any one of the following: the Select command, the Query command, or a new command generated based on the Select command and the Query command. The first command is used to select the tag that needs to be inventoried in at least one tag and start an inventory count.

[0183] If the reader has already obtained the length of the temporary identifier that the Tag can support, then execute steps 12 to 20 below. If the reader has not obtained the length of the temporary identifier that the Tag can support, then execute steps 21 to 24 and steps 12 to 20 below. If the length of the temporary identifier configured by the reader for the Tag is a length that the Tag cannot support, then execute steps 31 to 35 and steps 12 to 20 below.

[0184] Step 12: The reader indicates the Q value for contention access and the length of the temporary identifier to be used via the second command.

[0185] The second command is any one of the following: a new command generated in step 11, a Select command, a Query command, or a new command formed by merging Select and Query, and the length of the temporary identifier can be denoted as x, in bits.

[0186] Step 13: Generate the first random number for the first tag.

[0187] The first tag is based on the tag selected in step 11, and the first random number is [0, 2]. Q A random integer within the range of -1, which can be denoted as a counter.

[0188] Each tag has a counter.

[0189] Step 14: The reader sends the third command to the first tag.

[0190] The third command is the QueryRep command, which is used to decrement the counter of the first tag by 1.

[0191] Step 15: Repeat step 14, and if the counter of at least one tag in the first tag is 0, the second tag responds to the reader with a reply.

[0192] The Reply contains a temporary identifier of length x, which can be denoted as RNx, and the second tag is the tag in the first tag whose counter is 0.

[0193] Step 15a: The second Tag randomly generates x 0 / 1 bits as a temporary identifier; or, the Tag generates X 0 / 1 bits, and then truncates x bits as a temporary identifier.

[0194] Where X ≥ x.

[0195] Step 15b: The second tag selects a sequence (e.g., a set of low-correlation sequences) from a sequence set of length x as a temporary identifier; or, the tag selects a sequence from a sequence set of length X and then truncates x bits as a temporary identifier.

[0196] Step 16: The reader receives the reply sent by the second tag and decodes the reply.

[0197] Reply contains RNx.

[0198] Step 16a: If the reader successfully decodes RNx, the reader sends an ACK command to the second tag.

[0199] The ACK command includes RNx.

[0200] Step 16b: If the reader fails to decode RNx, the reader sends a NAK command to the second tag.

[0201] Step 17: The second tag receives the ACK command or NAK command sent by the reader / writer.

[0202] Step 17a: If the RNx contained in the ACK received by the second tag is the RNx sent by the tag, then a Reply is sent to the reader.

[0203] The Reply contains the inventory data uploaded to the reader and the RNx, and is used to indicate that the inventory of the Tag is complete.

[0204] Step 17b: If the RNx included in the ACK received by the second tag is not the previously sent RNx; or if the second tag receives a NAK, the second tag sets the counter to the maximum value.

[0205] Step 18: Repeat steps 14 to 17 until the reader finishes counting the first tag.

[0206] Step 19: The reader sends a QueryAdjust command to the first tag.

[0207] The execution order of step 19 can be any step after step 12. The QueryAdjust command is used to re-select at least one of the Q value and the temporary length identifier, where the Q value is denoted as Q' and the temporary identifier length is denoted as x'.

[0208] Step 20: The first tag performs the second operation.

[0209] The second operation is at least one of the following: regenerate a [0,2] array.Q A random integer in the range of '-1' is used as a counter. The temporary identifier of length x' used later can be regenerated according to steps 15a or 15b, or it can be truncated or padded based on the original identifier.

[0210] Optionally, the length of the temporary identifier that the Tag intends to use may be indicated in the Reply of step 15 or step 17a, as may be indicated in step 12a or 12b, which will not be elaborated here.

[0211] Step 21: The reader sends a first command to at least one tag.

[0212] The first command is used to select the tag that needs to be inventoried from at least one tag and start a round of inventory counting, and the first command is used to indicate a Q value.

[0213] Step 22: The third tag generates a second random number.

[0214] The third tag is based on the tag selected in step 21, and the second random number is generated based on the tag selected in step 21. The second random number is [0, 2]. Q A random integer within the range of -1, denoted as y.

[0215] Each tag has a counter.

[0216] Step 23: The third tag reports the length of the temporary identifier supported by the third tag in the subsequent y-th time slot.

[0217] Step 23a: The third tag directly indicates the minimum and maximum lengths of the supported temporary tags.

[0218] The maximum and minimum lengths of the temporary identifier supported by the third tag mentioned above can each be represented by 5 bits.

[0219] Step 23b: The third tag indicates the combination of temporary tag lengths supported.

[0220] Among them, the temporary identifier length combination supported by the above third tag can be represented by 2 bits [4-8], [8-16], [16-32], [32-64] (e.g. "00"→[4-8]; "01"→[8-16]; "10"→[16-32]; "11"→[32-64]).

[0221] Step 23a: The third tag indicates information related to the length of the temporary tag.

[0222] Among them, the information related to the length of the temporary identifier in the third tag mentioned above can be the tag model or version number.

[0223] Optionally, if the third tag carries the length of the temporary identifier expected to be used by the third tag in step 23, steps 12a or 12b above can be referred to, which will not be repeated here.

[0224] Step 24: The reader can repeat steps 21 to 23 until the length of the temporary identifier that can be supported for all tags is obtained, or perform only a limited number of loops.

[0225] It should be noted that when the reader performs a limited number of loops, the information obtained by the reader may be incomplete, which may cause the length of the temporary identifier obtained by some tags to be a length of the temporary identifier that is not supported by the configuration. In the above case, that is, when the length of the temporary identifier configured by the reader for the tag is a length that the tag does not support, the following steps 31 to 35 are executed.

[0226] Step 31: The reader sends a fourth command to at least one tag.

[0227] The fourth command can be a Query / QueryAdjust command, etc. The fourth command is used to select the tag that needs to be inventoried in at least one tag and start a round of inventory counting, and indicate a Q value and a temporary identifier length (denoted as x), and at least one tag does not support the use of a temporary identifier of length x.

[0228] Step 32a: The fourth tag generates the third random number.

[0229] The fourth tag is based on the tag selected in step 31, and the third random number is [0, 2]. Q A random integer within the range of -1, denoted as y.

[0230] Each tag has a counter.

[0231] Step 33: The fourth tag reports an error code or its supported temporary identifier length in the subsequent y-th time slot.

[0232] Step 33a: The fourth tag uses agreed-upon bit information to indicate and report error codes.

[0233] Step 33b and the fourth tag can be performed in the manner of steps 23a to 23c, indicating the supported temporary tag length.

[0234] Step 32b: The fourth tag enters rollback mode and selects one from all the agreed-upon optional temporary tags as a temporary tag.

[0235] Step 34: When the reader finds that the length of the temporary identifier of the fourth tag is different from its indication value, the reader uses the agreed-upon backoff mode temporary identifier length to decode the temporary identifier sent by the fourth tag later.

[0236] Step 32c: The fourth tag enters rollback mode and uses the original temporary tag length.

[0237] Step 35: When the reader finds that the length of the temporary identifier of the fourth tag is different from its indication value, the reader uses the original temporary identifier length of the fourth tag to decode the temporary identifier sent by the tag later.
