Background

Currently, in a conventional radio frequency identification (Radio Frequency Identification, RFID) backscatter communication (Backscatter Communication, BSC) system, a plurality of BSC devices (i.e., electronic Tag tags) can acquire opportunities to transmit data through a contention type access procedure, such as a random time access based on Q value and a temporary identification check based on 16-bit random numbers.

However, in the above method, the BSC apparatus needs to constantly transmit a 16-bit temporary identity during the contention process so that the temporary identity is correctly and uniquely identified by the reader/writer. Because the length of the temporary identifier adopted at present needs to occupy a large amount of communication resources and storage resources, the fixed temporary identifier length also causes the access mechanism to lack flexibility, and if the temporary identifier length is insufficient, a plurality of BSC devices are easy to generate the same temporary identifier, so that a larger collision probability is caused, and the communication success rate is reduced, so how to configure the temporary identifier for the BSC devices is a problem to be solved urgently.

Some concepts and/or terms related to the information indication method, the information indication device, the target device and the storage medium provided by the embodiments of the present application are explained below.

Backscatter communication refers to a backscatter communication device (hereinafter referred to as BSC device) that uses radio frequency signals in other devices or environments to perform signal modulation to transmit information. The BSC device may be a Tag in a conventional RFID, or a Passive internet of things (Internet of Things, ioT) User Equipment (User Equipment) UE.

The BSC apparatus controls the reflection coefficient Γ of the circuit by adjusting its internal impedance, thereby changing the amplitude, frequency, phase, etc. of the incident signal to achieve modulation of the signal.

It should be noted that the reflection coefficient of the signal can be characterized as:

wherein Z is ₀ For the characteristic impedance of the antenna, Z ₁ Is the load impedance. If the incident signal is assumed to be S _in (t) the output signal isThus, by reasonably controlling the reflection coefficientCorresponding amplitude modulation, frequency modulation or phase modulation.

Currently, the architecture of typical backscatter communications can be divided into single-base systems and dual-base systems.

Single base system

FIG. 2 shows a schematic diagram of a monostatic backscatter communication system, typically represented by a conventional RFID system, as shown in FIG. 1, comprising a BSC device (e.g., tag) and a reader, the reader comprising an RF source and a BSC receiver; wherein the RF radio frequency source is configured to generate an RF radio frequency signal to power the BSC apparatus. The BSC apparatus transmits the RF radio frequency signal modulated by the backscatter to the BSC receiving end in the reader-writer, and the BSC receiving end in the reader-writer receives the RF radio frequency signal and then demodulates the signal, and because the RF radio frequency source and the BSC receiving end are in the same apparatus, for example, the reader-writer, the system is called a single-base backscatter communication system.

In the single-base backscatter communication system, since the RF radio frequency signal transmitted from the BSC apparatus experiences a double near-far effect caused by signal attenuation of the round trip signal, the energy attenuation of the signal is large, so that the single-base system is generally used for short-range backscatter communication, such as a conventional RFID system.

Dual base system

Fig. 3 shows a schematic diagram of a bistatic backscatter communication system, where the RF source and BSC receiver are separated, as shown in fig. 3. Thus, the bistatic system avoids the problem of large round trip signal attenuation, and further improves the performance of the backscatter communication system by reasonably locating the RF source.

Information transmission between reader-writer and Tag in RFID

Fig. 4 shows a schematic diagram of states of a reader-writer and a Tag, as shown in fig. 4, in an EPC C1G2 RFID system defined in the current ISO 18000-6C, a series of control commands of the reader-writer and states of the Tag are defined, as shown in fig. 4, table 1 and table 2, in actual use, the reader-writer sends a control command to the Tag, and the Tag receives the control command, so that the states of the Tag are changed, and meanwhile, the Tag can reply corresponding data to the reader-writer according to the control command and the states where the control command is located.

Table 1: control command for reader/writer

Table 2: state of Tag

Single Tag (contention free) transmit-receive flow chart

Fig. 5 shows a flow chart of receiving and transmitting data by a single Tag (i.e. in a contention-free scenario), as shown in fig. 5, in the inventory mode, after a reader transmits a Query command (Query), the Tag responds with a response (Reply), taking the Reply as RN16 as an example, the Tag generates a 16-bit random number and transmits the random number to the reader, and then the reader transmits the sequence to the Tag through an ACK command, so that after the Tag successfully verifies the RN16 in the ACK, the subsequent data can be transmitted to the reader.

Multi-Tag contention access procedure

Fig. 6 shows a schematic diagram of a multi-Tag contention access procedure, and as shown in fig. 6, the multi-Tag contention access procedure includes the following steps 1 to 13 in the inventory mode.

Step 1, a reader sends a Select command to Select a Tag to be checked

Step 2, the reader sends a Query command to start a round of inventory, and the Query indicates a Q value

Step 3, generating a random integer by all tags as an initial value of the counter

Wherein the value range of the random integer is [0,2 ] ^Q -1]

Step 4, checking whether the counter is 0

In step 5a, when the counter of at least two tags is 0, the Tag with the counter of 0 sends a Reply, which includes a randomly generated 16-bit random number, and is denoted as RN16.

And step 5b, when the Tag-free counter is 0, the reader transmits a QueryRep command.

In step 6a, if the reader/writer successfully decodes the RN16, the reader/writer sends an ACK command, which includes the RN16 and the command field of 2 bits.

Step 6b, in case the reader/writer fails to decode RN16, the reader/writer sends a NAK command.

Step 7, the Tag receives the ACK and checks whether the RN16 included in the ACK is the RN16 transmitted before.

In step 8a, when the RN16 is correct, the correct Tag of the RN16 is checked to send data to be reported, such as PC, XPC, EPC or other data, to the reader to indicate that the Tag checking is completed.

In step 8b, in case of an RN16 error, the Tag that verifies the RN16 error sets its own counter to a maximum value.

And 9, if the Tag receiving the NAK command sends a Reply at the last adjacent time sequence, the Tag sets the self counter to be the maximum value.

Step 10, the Tag receiving the QueryRep command counts itself to be-1.

Step 11, the reader/writer may send a query adjust command to reconfigure a Q value.

Step 12, receiving a QueryAdjust command and randomly selecting an integer as a counter again by the Tag of the incomplete inventory.

Wherein the value range of the integer is in the range of [0,2 ] ^Q -1]。

And step 13, repeating the steps 4-12 until all the Tag counting is completed.

It should be noted that, if there is a counter of 0 that is just greater than 1 Tag and the same RN16 is just used, then the tags will check that the ACK is successful in step 7 and send data at the same time subsequently, so that the reader-writer fails to decode, which is called contention access and temporary identifier collision.

As can be seen from the above, the multi-Tag contention access of the RFID is composed of two parts, namely, the random time access based on the Q value and the temporary identification check based on the RN16, and in the contention access opportunity process, the Tag needs to repeatedly send the RN16 until the RN16 is correctly and uniquely identified by the reader/writer.

Thus, the use of fixed length temporary identifications makes the overall access mechanism inflexible. On the one hand, when the number of BSC devices is not large or the communication reliability requirement is not high, using the temporary identity that is too long requires occupying a large amount of communication resources and storage resources, especially for BSC systems with weak storage capacity and low rate. On the other hand, when the number of BSC devices is large or the communication reliability requirement is high, the insufficient length of the temporary identifier easily causes a plurality of BSC devices to generate the same temporary identifier, and a large collision probability is caused, so that subsequent communication failure is caused.

Aiming at the competition access process of the back scattering communication, the embodiment of the application provides a length information indication method of the BSC equipment temporary identifier.

It should be noted that, the information indication method provided by the embodiment of the application can be implemented in the existing checking flow defined by the ISO 18000-6c RFID system, and is also applicable to the checking flow or the data reading flow defined by other systems, and the information indication method provided by the embodiment of the application is illustrated by taking the existing checking flow defined by the ISO 18000-6c RFID system as an example, and the checking flow or the data reading flow defined by other systems is also within the scope of the protection of the embodiment of the application. The information indication method provided by the embodiment of the application can be applied to all back scattering communication systems, including RFID, LTE, NB-IoT, NR, IEEE 802.11 evolution systems and the like.

The information indication method provided by the embodiment of the application is described in detail below through some embodiments and application scenes thereof with reference to the accompanying drawings.
